If you own a business that requires the filling of drums, totes, and other large containers, you know that the success of your company is heavily dependent on the quality and features of your drum filling machine . If you are in the market for new water filling machines , here are some things to look for when doing your research.
What Should Come Standard?
First of all, find a manufacturer that produces drum filling machines that come with many of the features you are looking for standard:
-- Swivel arms: Being able to fill barrels with your product effectively is the name of the game. The swivel arms of your machine should come with a wide variety of functions that will suit just about any application you may need them for. Such features include: nozzle height adjustment capabilities, nozzle park/unpark options, nozzle dive, and many others.
-- Scale: One of the best quality assurance tools is the scale that measures the amount of product being loaded per unit. Look for one that is made from easy-care stainless steel with a digital readout and that is easily integrated with all of the other essential operating controls.
-- Ease of Load/Unload: An easy system for getting the barrels on and off the loading platform should also come standard. The best one features an operator actuated powered roller conveyor for maximum control and efficiency and fewer problems.
What Else Should I Look For?
Look for a manufacturer that can customize your machine with added systems that are a step beyond what comes standard. All products should come with a 30-day performance guarantee as well as a limited warranty for parts and service.
At first glance, water filling machines application involving the transportation of a liquid product into a solid vessel may seem simple. However what few people realise is the high accuracy and feed rates required for such high-precision and high-speed applications. The complex requirements of transporting the vessels, usually in the form of bottles, inserting the filling nozzle and controlling the flow rate of the liquid product, requires a highly capable function controller to handle the speed of the process. Finding the right automation solution to meet these requirements is a challenge for most engineers that CBI solves by providing a Mitsubishi solution that is simple and cost effective.Advanced control using electronic cammingEnsuring that the control of the filling nozzle is synchronised with the rotational conveyor and flow controller is the challenge for most bottle filling machine . applications.
The controller has to ensure that the liquid is fed accurately into the bottle filling machine. opening. The flow rate and the nozzle height also have to be precisely controlled so as to eliminate the risk of frothing and overflow of the liquid. By using Mitsubishi Electric’s motion controller CPU (based on the Q series automation platform), cam profile can be controlled intelligently with a software camming system that replaces hardware-based methods. The system is very flexible; when the bottle filling machines . type has to be changed, the cam profile software can be simply exchanged eliminating the need for a system overhaul.Linking high-speed networksIn addition to the motion controller, the actual transfer and conveyor aspect of the application can be controlled using Mitsubishi Electric’s intelligent and energy saving inverters FR-A700 via the open device level network CC-Link, centralised on the Q series controller.
The fast rate bottle feed into the machine can be controlled by the Q series together with CC-Link network offering high-speed transmission of 10ﾠMbps with program execution in milliseconds. The Q series also enable connectivity to higher level systems via its Ethernet option module allowing real-time production data to be fed into ERP and MES systems. This continuous monitoring allows factory managers to report on actual bottling performance in real time without having to rely on statistical data. The high-speed servo drives are controlled directly by the motion controller on the Q series platform via high-speed SSCNET III, fibre-optic network. The network achieves speeds of up to 50ﾠMbps ensuring high speed and high accuracy. The cam profiles can be easily switched using the GOT1000 human machine interface touch screen, providing a user friendly interface to the bottle filling machine .
Boilers can be classified into the following configurations:
"Pot boiler" or "Haycock boiler": a primitive "kettle" where a fire heats a partially-filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere. These could burn wood or most often, coal. Efficiency was very low.
Fire tube boiler . Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space). This is the type of boiler used in nearly all steam locomotives. The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface just below boiling point. The furnace can be situated at one end of a fire-tube which lengthens the path of the hot gases, thus augmenting the heating surface which can be further increased by making the gases reverse direction through a second parallel tube or a bundle of multiple tubes (two-pass or return flue boiler); alternatively the gases may be taken along the sides and then beneath the boiler through flues (3-pass boiler). In the case of a locomotive-type boiler, a boiler barrel extends from the firebox and the hot gases pass through a bundle of fire tubes inside the barrel which greatly increase the heating surface compared to a single tube and further improve heat transfer. Fire-tube boilers usually have a comparatively low rate of steam production, but high steam storage capacity. Fire-tube boilers mostly burn solid fuels, but are readily adaptable to those of the liquid or gas variety.
Water tube boiler . In this type,the water tubes are arranged inside a furnace in a number of possible configurations: often the water tubes connect large drums, the lower ones containing water and the upper ones, steam and water; in other cases, such as a monotube boiler, water is circulated by a pump through a succession of coils. This type generally gives high steam production rates, but less storage capacity than the above. Water tube boilers can be designed to exploit any heat source and are generally preferred in high pressure applications since the high pressure water/steam is contained within small diameter pipes which can withstand the pressure with a thinner wall.
Fire-tube boiler with Water-tube firebox. Sometimes the two above types have been combined in the following manner: the firebox contains an assembly of water tubes, called thermic syphons. The gases then pass through a conventional firetube boiler. Water-tube fireboxes were installed in many Hungarian locomotives, but have met with little success in other countries.
Sectional boiler. In a cast iron sectional boiler, sometimes called a "pork chop boiler" the water is contained inside cast iron sections. These sections are assembled on site to create the finished Industrial Boiler .
The object underlying the invention is achieved by a water-cooled firing grate , which consists of a plurality of blocks of grate bars extending over the width of the grate, each block consisting of multiple grate bars, wherein each grate bar has a meander-shaped channel in addition to several cut-in grate slots inside. The grate bars are furthermore connected with each other by screwable connecting pieces such that a grate slot is formed between two grate bars. In the interior of the connecting pieces a connecting passage extends, which connects the meander-shaped channels of two grate bars. The grate bars positioned on the boundaries of the grate have screwable inlet and outlet pieces, through which the liquid coolant water is supplied and discharged.
In accordance with the invention the travelling grate bars lie on the connecting, inlet and outlet pieces and screwed to the connecting, inlet and outlet pieces by means of vertically extending screws. The large contact area and the screw connection lead to a good fixation of all workpieces and a safe sealing of the cooling system.
In some cases it turned out to be expedient when a horizontal, air-cooled firing grate known per se is provided downstream of the inventive firing grate. In this way, a high burn-out of the fuel is advantageously achieved, although the thermal load-bearing capacity of the air-cooled firing grate is only 0.5 to 0.8 MW/m 2 grate area. Alternatively, a second inventive, horizontal, water-cooled firing grate can be provided downstream of the inventive firing grate, so that a high fuel burn-out is achieved with a high load-bearing capacity of the grate.
The postcombustion can be improved in accordance with the invention in that at the upstream side of the second air-cooled or water-cooled firing chain grate nozzles are provided, through which pulsed combustion air is introduced into the combustion space, where the pulsed air may also be preheated.In accordance with the invention the horizontal, air-cooled firing grate provided subsequent of the inventive firing grate has connecting and end pieces, which have no connecting passages, but are otherwise designed corresponding to the connecting, inlet and outlet pieces.
