Description

Technical Field

[0001] The utility model belongs to the technical field of membrane filter plates, and in particular relates to a membrane filter plate used for a filter press. Background Art

[0002] A filter press is a mechanical device used for solid-liquid separation. The filter press filters the mixed liquid through several diaphragm filter plates. By squeezing several diaphragm filter plates to reduce the distance between the diaphragm filter plates, the mixed liquid can be filtered, and the filtered filter cake will be clamped on the inside by several diaphragm filter plates. When the distance between two adjacent diaphragm filter plates is pulled apart, the filter cake can fall down and separate from the diaphragm filter plates due to gravity. However, there is a certain friction between the filter cake and the filter plate, and the moisture in the filter cake is not completely filtered dry. Therefore, when the two filter plates are separated, the filter cake cannot fall automatically, and manual unloading is required, which increases manual work intensity and reduces work efficiency. Utility Model Content

[0003] The utility model provides a diaphragm filter plate for a filter press, which has the characteristic that when the distance between two diaphragm filter plate bodies is enlarged, through the connection, the movable shaft between the two diaphragm filter plate bodies can be pulled down to push the filter cake downward, which is beneficial to automatic unloading of the filter cake.

[0004] The lockhole that is formed on the two ends of the support frame is that the support hole is set at the bottom, and the position of the locking plate is set at the bottom, and the positioning plate is fixed with a button bar at the bottom, and a button bar at the bottom of the support frame is provided with a button bar at the bottom.

[0005] The positions of the first slide groove and the second slide groove correspond to each other, and one side of the fixing plate is flush with one side of the membrane filter plate body.

[0006] Wherein, connecting shafts are provided at both ends of the movable shaft, and a limit block is provided at one end of the connecting shaft away from the movable shaft.

[0007] Wherein, a through hole is opened on the connecting block, and the connecting shaft is rotatably connected to the inner side of the through hole.

[0008] Wherein, a through slot is provided inside the second fixing block, and the second fixing block is slidably connected to the inner side of the through slot.

[0009] The beneficial effect of the utility model is that when the distance between the two membrane filter plate bodies is enlarged, the movable shaft located between the two membrane filter plate bodies can be pulled down through the connection, so that the filter cake can be pushed downward, avoiding the situation that the filter cake cannot automatically fall due to the large friction between the filter cake and the membrane filter plate body, which is beneficial to the automatic unloading of the filter cake; and when the distance between the two membrane filter plate bodies is reduced, the movable shaft can be driven to slide up and reset through the spring, thereby avoiding the situation that the movable shaft interferes with the movement of the membrane filter plate body.
