Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge treatment filtering and impurity removal device. Background Art

[0002] Sludge treatment is the process of reducing, stabilizing and harmless treatment of sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must have sludge treatment facilities.

[0003] Announcement No. (CN218281968U) discloses a filtering and impurity removal mechanism for sludge treatment, which starts a driving motor and a second electric push rod, wherein the driving motor drives the mounting shaft and the crushing rod to rotate, and the second electric push rod drives the cross plate and the crushing assembly to move back and forth as a whole, so that the crushing rod can cooperate with the up and down reciprocating movement during the rotation process to crush the sludge, and then decompose the sludge into smaller particles, thereby facilitating the sludge filtering and reducing the occurrence of blockage. The above-mentioned device uses a filter plate to filter impurities in the sludge, but the flow rate of the sludge is relatively slow in the natural state, which causes the sludge to pass through the filter plate at a relatively slow speed, which affects the filtering efficiency and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a sludge treatment, filtering and impurity removal device in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A sludge treatment filtering and impurity removal device comprises a support mechanism and a filtering mechanism for filtering and impurity removal of sludge, wherein the filtering mechanism is installed above the support mechanism;

[0007] The filtering mechanism includes a bearing plate, a fixed box installed above the bearing plate, a filter cartridge arranged inside the fixed box, a limit ring fixed above the filter cartridge, a handle fixed above the limit ring, a positioning block installed above the fixed box, a discharge pipe installed on the inner side of the bearing plate, an extrusion assembly arranged at the rear of the fixed box, the extrusion assembly includes a guide plate, a vertical plate fixed at the rear of the guide plate, a cylinder fixed at the rear of the vertical plate, a drive box fixed at the telescopic end of the cylinder, a slider fixed below the drive box, a motor fixed above the drive box, a threaded rod installed at the output end of the motor, a threaded block installed outside the threaded rod, a connecting rod installed in front of the threaded block, and an extrusion plate fixed at the end of the connecting rod away from the threaded block.

[0008] Preferably, the supporting mechanism comprises a supporting frame, and the diagonal rod is fixed on the supporting frame.

[0009] Preferably, a reinforcement mechanism is installed inside the filtering mechanism, and the reinforcement mechanism includes a central block, a reinforcement plate is fixed on the outside of the central block, and a vertical rod is fixed below the reinforcement plate.

[0010] Preferably, the oblique rod is welded to the support frame, and the angle between the oblique rod and the support frame is forty-five degrees.

[0011] Preferably, the thickness of the slider is half of the thickness of the guide plate, and the motor is connected to the drive box by bolts.

[0012] Preferably, the reinforcement plates are welded to the central block, and the number of the reinforcement plates is four.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] By setting up a filtering mechanism, when using the device, the sludge to be treated is added to the inside of the filter cartridge, and the motor is started. The operation of the motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the threaded block to descend. The threaded block drives the extrusion plate to descend through the connecting rod. The extrusion plate descends to squeeze the sludge in the filter cartridge. The sludge flows rapidly under the action of pressure, and the fast-flowing sludge passes through the sieve holes on the filter cartridge. Impurities in the sludge are trapped inside the filter cartridge, and the filtered sludge is discharged through the discharge pipe. The above method can increase the flow rate of the sludge, thereby effectively improving the filtering efficiency of the sludge. BRIEF DESCRIPTION OF THE DRAWINGS
