This invention relates to an improvement in a device for extracting pressurized water from the diaphragm in a filter press that uses a diaphragm to compress and dewater.

流下のみをさせるものもある。"Prior Art" Examples of pressurized water extraction devices for this type of filter press include Utility Model Publication No. 55-42803 and Utility Model Publication No. 54-45578. In these methods, to remove pressure from the diaphragm after squeezing, an outlet is opened to allow the liquid to flow down naturally, and then a vacuum pump is used to remove the remaining liquid. There are also those that allow only natural flow.

作も複雑となる問題がある。``Problems to be Solved by the Invention'' The filter press is a batch-type filter, and therefore, the shorter the time for opening and closing of the plates that do not involve excessive pressure and the time for drawing out the pressure water in the diaphragm, the better the filtering efficiency will be. For this reason, as mentioned above, it takes time to extract the pressure water from the diaphragm under gravity flow, so a vacuum pump is used to extract it. However, conventional extraction by gravity takes time, and it is difficult to retract the diaphragm and restore the overchamber after extraction. In addition, when extracting pressure water using a vacuum pump, not only is the vacuum pump expensive, but a tank is required to separate air and water, making the equipment expensive and complicated to operate. There is a problem.

の排水路にエジエクタを設けたものである。"Means for Solving the Problems" This invention solves the above-mentioned problems at once by using the suction force of an ejector in place of the conventional vacuum pump. The gist is that a large number of plates are lined up in parallel on a pair of guide rails so that they can be opened and closed, and when these plates are closed, liquid such as sludge is poured into the chamber formed between each plate. After press-fitting, further
In a filter press in which pressurized water is injected into a diaphragm provided in each of the overchambers to squeeze out the overcake, an ejector is provided in a drainage path for the pressure water from the overchambers.

In order to discharge the pressure water in the diaphragm after squeezing, first open the valve 3 to release the pressure in the diaphragm, and then Close this after the time has passed. At this time, a small amount of water will drain out.
Next, when the pump 10 is started to supply fresh water from the wash water tank 9 to the ejector 7, the water in the diaphragm is sucked by the ejector 7, passes through the automatic valve 5 and the ejector 7, and is discharged to the wash water tank 9. be done. Note that the automatic valves 5 and 8 are automatically opened after the valve 3 is closed.

る。``Effects'' As explained above, this device uses the negative pressure of the ejector to forcibly remove the water inside the diaphragm, and can remove the water in a much shorter time compared to natural flow. In addition, compared to using a vacuum pump, since an ejector is used, there is no need for an air supply device or water separation device, and the machine can be manufactured at a low cost. It has a simple structure, has no failures, and has superior effects compared to conventional devices.
