The present invention relates to a filter plate equipped with a filter cloth cleaning device and a filter cake batch discharge type filter press provided with a plurality of filter plates. More specifically, the filter cake enclosed in the filter cloth when dismantling the filter plate of the filter press, which is a compression filtration dehydrator, The present invention relates to a filter cloth cleaning technique and a batch dispensing technique of filter cakes, in which the discharge is simultaneously and simultaneously, and the filter cloth clogging phenomenon in the subsequent process can be eliminated.

Used in many industries such as food, chemical, civil engineering, construction, and environment, the filter press is a device in which the suspension supplied into the device is compressed and removed by sludge in the form of water and solids by the solid and liquid separation action of the filter cloth. In general, the filter cake produced during the compression / filtration / dehydration process of the filter press is somewhat viscous, even if the filter plate is disintegrated, there is a problem that all of the filter cake sandwiched between the filter cloth is not completely removed by gravity free fall method.

For this reason, the filter cloth is scraped by manual or automated equipment to remove the residue that has not been completely removed from the filter cloth. However, the filter cloth is not easily removed by the scraper. This blockage had the disadvantage of making the filtration of the next process very difficult.

In order to solve this problem, washing the filter cloth with high pressure water or vibration technology is applied, but in the case of microbial digested sludge, the viscosity is 3,000cp, the situation is not getting a satisfactory effect.

The present invention has been researched and developed in order to solve the above-mentioned conventional problems, and the main object thereof is to discharge the sticky filter cake (sludge) sandwiched between the filter cloths at the same time, and cleanly remove the residue of the filter cake from each filter cloth. The present invention provides a filter plate equipped with a new type of filter cloth cleaning device capable of discharging, and additionally, filter cloth clogging phenomenon in the next process, and a filter cake batch discharge type filter press equipped with the filter plate.

In addition, the present invention by spraying the compressed air of high pressure to the filter cloth with sludge adhered to give a strong throttle vibration with a momentary impact on the filter cloth, the compressed air is moved from the rear side of the filter cloth to the front clogging phenomenon of the filter cloth In addition, there is another purpose to solve the problems such as filter cloth damage and pull caused by using the high pressure water in the prior art at once.
