At present, the commonly used equipment for sludge dewatering includes belt filter press, centrifugal dewatering machine and plate and frame filter press. The moisture content of sludge after dewatering by belt filter press and centrifugal dewatering machine is 80%, which cannot meet the subsequent sludge landfill or incineration requirements. After dewatering by plate and frame filter press, the moisture content of sludge can reach below 60%, which can meet the requirements of sludge landfill or incineration. This also makes the use of plate and frame filter press more and more common. After dewatering by plate and frame machine, the sludge with a moisture content of less than 60% sticks to the filter plate and is not easy to fall off. Although the plate and frame filter press has its own automatic mud unloading system, it needs to be unloaded by vibration, which is not ideal and requires manual assistance for mud unloading.
[0003] The pushers currently used by workers generally have wooden handles, which are very easy to loosen during use. In addition, wooden handles are prone to cracking, moisture, and mold, and have a very short service life. Frequent reinforcement and maintenance are required, which wastes time and reduces the work efficiency of workers. Utility Model Content
[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a mud pushing plate for a plate-type filter press.

[0007] Furthermore, it also includes a spring, which is arranged between the transverse push plate and the side push plate to help the mud cake fall off.
[0008] Furthermore, the handle and the shovel head are detachably connected to facilitate replacement and installation of the shovel head.
[0009] Furthermore, shovel heads are provided at both ends of the handle. When two plate filter presses are running at the same time, a worker can stand between the two filter presses and operate them without turning the handles, which saves time and facilitates the workers to unload mud.
[0010] Furthermore, it also includes a sliding sleeve, which is slidably arranged on the outside of the handle, and a cavity for accommodating the transverse push plate and the side push plate is provided in the sliding sleeve for easy storage.
[0011] Furthermore, a cap is provided at the intersection of the transverse push plate and the side push plate to protect the filter cloth on the plate filter press from being damaged.
[0012] Furthermore, the handle includes two sections, namely handle one and handle two, and the two sections are connected by a hinge to facilitate folding of the handle for easy storage.
[0013] Furthermore, the transverse thrust plate and the side thrust plate are integrally formed, and when there is no spring, elastic steel is used, which can make the structure simpler and achieve the same function.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The mud pusher plate of the plate filter press of the utility model is detachable and has a long service life. It does not need to be frequently reinforced and maintained, which reduces the labor intensity of workers and improves work efficiency. The utility model has good connection firmness, and the head design can protect the filter cloth on the plate filter press from being damaged, saving equipment maintenance costs. It has a simple structure. When the worker operates to discharge the mud cake from the pressure filter press, he only needs to stick the horizontal push plate to the filter cloth side of the plate and frame filter press and push it inward. As it is pushed inward, the force on the side push plate continues to increase, the spring is continuously compressed, and the reaction force causes the mud cake to fall off the filter cloth, reducing the labor intensity of workers and further improving work efficiency.
