Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a mud cake discharging device for a plate and frame filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filtering medium to apply a certain pressure to an object to allow liquid to dialyze out. It is a commonly used solid-liquid separation device. It has been applied to chemical production since the early 18th century and is still widely used in industries such as chemical engineering, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection.

[0003] In the prior art, after the plate and frame filter press completes the solid-liquid separation work, the filter plate surface will remain with the filtered mud cake.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0016] 1. In the present utility model, in order to facilitate the separation of the filter plate body and the discharging of the filter cake after the filter separates solid and liquid, mounting frames are fixedly connected to both sides of the filter plate body. Movable grooves are formed on both sides of the mounting frame. Four mounting grooves are formed inside the movable groove. Springs and telescopic rod 1 are installed inside the mounting grooves. The ends of the spring and telescopic rod 1 are connected to a top plate. When the filter works, the hydraulic telescopic rod is started. The hydraulic telescopic rod drives the push plate to push and squeeze the filter plate body. At the same time, the baffle pushes and squeezes the top plate. When multiple filter plate bodies come into contact, the adjacent top plates will squeeze each other, which can play a certain buffering role in the extrusion of the filter plate body. After the work is completed and the hydraulic telescopic rod drives the push plate to reset, the adjacent two filter plate bodies push the top plate under the action of the spring, separating the two filter plate bodies, so that the filter cake can fall, facilitating the operation of workers.

[0017] 2. When cleaning the adhered mud cake in the present utility model, an external controller is used to start the blower. After the blower starts, strong wind is generated. The wind force is sent into the air supply trough through the connecting hose and blown out from the two side air outlets. The worker pulls the conical platform through the handle, and then drags the sliding table to slide through the second telescopic rod. After the conical platform is located above the middle of the two filter plate bodies, the conical platform is pulled downward so that the bottom end of the conical platform is inserted into the middle of the two filter plate bodies. The wind blown out from the two side air outlets will blow off the mud cake adhered to the surface of the filter plate body and make it fall. Moreover, the air outlets are inclined downward, which is convenient for blowing off the mud cake on the surface of the filter plate body. By this way, the unloading of the mud cake is completed, and the working efficiency of the worker can be improved. Description of the Drawings

The worker pulls the conical platform 601 through the handle 602, and then drags the sliding table 501 to slide through the second telescopic rod 504. After the conical platform 601 is located above the middle of the two filter plate bodies 301, the conical platform 601 is pulled downward, so that the bottom end of the conical platform 601 is inserted into the middle of the two filter plate bodies 301. The wind blown out from the two air outlets 604 will blow off the filter cake adhered to the surface of the filter plate body 301 and make it fall. Moreover, the air outlets 604 are inclined downward, which is convenient for blowing off the filter cake on the surface of the filter plate body 301. By this way, the discharging of the filter cake is completed, which can improve the working efficiency of workers.
