Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to an efficient discharging device for a filter press. Background Art

[0002] The basic working principle of a filter press is to use an external pressure to make the mixed liquid pass through the filter plate. Solid particles are intercepted on the filter plate to form a filter cake, while the liquid passes through the filter plate and is collected as filtrate. After the filtration process is completed, the filter press needs to be cleaned to remove the filter cake on the filter plate.

[0003] For example, a discharging device for a filter press disclosed in Chinese Patent Publication No. CN219922182U includes a supporting clamping plate for limiting. A servo motor for driving is arranged at a position close to the bottom of the side end face of the supporting clamping plate. A connecting turntable is fixedly installed at the center of the front end face of the servo motor, and a guiding clamping shaft is arranged at a position close to the outside of the front end face of the connecting turntable.

[0004] When the existing efficient discharging device of a filter press is discharging, the filter cake is usually directly cleaned from the filter plate. The cleaned filter cake will become filter residue blocks of different sizes, which cannot be directly recycled. It needs to be further crushed into filter residue strips with smaller volume and more uniform shape before it can be recycled by the recycling equipment. Therefore, a new cutting device needs to be set up to recycle the filter residue, which increases the cost of the factory for treating waste residue. Summary of the Invention

[0005] The purpose of the utility model is to solve the problem that when the existing efficient discharging device of a filter press is discharging, the filter cake is usually directly cleaned from the filter plate, and the cleaned filter cake will become filter residue blocks of different sizes, which cannot be directly recycled in the prior art, and to propose an efficient discharging device for a filter press.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: An efficient discharging device for a filter press includes a mounting plate, a limiting rod, a roller, a pressing plate, a filter plate and a driving component. A filtering groove is formed on one side of the filter plate, and a plurality of dividing components are movably clamped inside the filtering groove. Each dividing component includes a movable rod, one end of the movable rod is fixedly connected with a dividing blade, the other end of the movable rod is fixedly connected with a pressing plate, and an extrusion object placing groove is formed on one side of the pressing plate. The dividing blade is arranged between the pressing plate and the filter plate.

[0007] Preferably, the driving assembly includes a driving plate, one side of the driving plate is fixedly connected to a pressing plate, one side of the driving plate is symmetrically and rotatably clamped with a first transmission rod, the other ends of the two first transmission rods are rotatably clamped with a driving groove, a driving shaft is threadedly connected inside the driving groove, one end of the driving shaft is drivingly connected to a driving motor, and the other end of the driving groove is rotatably clamped with a second transmission rod.

[0008] Preferably, mounting shafts are respectively fixedly connected to the four corners of the pressing plate, and the rollers are rotatably clamped outside the mounting shafts.

[0009] Preferably, the two limiting rods are arranged at both ends of the roller.

[0010] Preferably, a rolling groove is formed on the outer side of the roller.

[0011] Preferably, one end of the movable rod is movably sleeved with a spring, and the spring is arranged between the pressing plate and the filter plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, the material is cut into smaller filter residue strips by using a splitting blade. When the driving motor rotates in reverse, the extrusion of the material by the pressing plate is released, and the extruded and cut material strips fall into the inner part of the material groove under the action of gravity, completing the automatic blanking operation. Thus, there is no need to set up a new cutting device to cut and recycle the filter residue, reducing the cost of the factory for treating waste residue.

[0014] 2. In the present utility model, when the driving motor rotates in reverse to release the extrusion of the material by the pressing plate, the spring converts the elastic potential energy stored in it into a thrust force, pushing the pressing plate to move outward. The pressing plate pushes the filter residue strips down from one side of the filter plate, completing the automatic blanking. By using the spring to push the pressing plate to move outward, the blanking efficiency of the high-efficiency blanking device of this filter press can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically describe the specific settings and functions of this embodiment below. Place the material to be extruded between the inside of the extrusion material placement groove 41 and the filter plate 5 respectively. The driving motor 65 drives the driving shaft 64 to rotate, and the two driving grooves 63 move towards each other, causing the first transmission rod 62 and the second transmission rod 66 to rotate and push the driving plate 61 towards the filter plate 5. The driving plate 61 drives the pressing plate 4 to extrude the material. At this time, the dividing blade 522 cuts the material into smaller filter residue strips.

[0026] As Figures 1-6 shown, it includes a mounting plate 1, a limiting rod 2, a roller 3, a pressing plate 4, a filter plate 5 and a driving component 6. A pressure filtration groove 51 is formed on one side of the filter plate 5, and a plurality of dividing components 52 are movably clamped inside the pressure filtration groove 51. The dividing component 52 includes a movable rod 521.

When the driving motor 65 rotates in reverse, the extrusion of the materials by the pressing plate 4 is released, and the extruded and cut material strips fall into the interior of the material groove under the action of gravity, completing the automatic feeding operation.
