Description

Technical Field

[0001] The utility model relates to the field of filter pressing devices, in particular to a filter pressing device for environmental protection engineering. Background Art

[0002] Environmental protection engineering filter press is a solid-liquid separation equipment used in the field of environmental protection. It mainly separates the solid particles suspended in wastewater or waste liquid by filter pressing, thereby purifying the liquid and reducing the volume of solid waste.

[0003] Application number: CN202420214380.8, discloses a plate pulling device for a filter press and a filter press, which completes the plate pulling process through the coordinated arrangement of structures such as a transmission chain, a plate puller, and a pressure wheel. Specifically, during the rotation of the transmission chain, the plate pulling hook is driven to smoothly pass under the filter plate that has not been pulled apart in the first state, and when it reaches the filter plate that has not been pulled apart at the front, the plate pulling hook switches to the second state and hooks the filter plate to move toward the direction of the pressing plate; when the filter plate is pulled to the position of the pulled apart filter plate or the pressure wheel position, the plate pulling hook switches to the first state and smoothly passes under the pulled apart filter plate or the pressure wheel, thus completing a plate pulling process. In the process of pulling apart each filter plate, each plate puller can move with the transmission chain. Compared with the traditional plate puller that needs to turn back and forth every time a filter plate is pulled apart, the plate pulling device provided by the utility model significantly improves the filter plate pulling speed, thereby improving production efficiency;

[0004] However, when the filter press device for environmental protection engineering is in use, a certain amount of solid-liquid mixture residue will adhere to the filter plate and the filter screen. Compared with the filter press in the patent, it is difficult to fully and timely clean the residue attached to the filter plate and the filter screen, which may cause the filter screen to be blocked, affecting subsequent use. For this reason, we propose an environmental protection engineering filter press device. Utility Model Content
