Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a material cleaning device for the discharge trough of a disc vacuum filter. Background Technology

[0002] A disc vacuum filter is a solid-liquid separation device that uses vacuum as the filtration power. Through technologies such as filter disc guide frame, variable speed stirring, back-blowing unloading, and automatic centralized lubrication, it achieves efficient and stable solid-liquid separation. The discharge trough of the disc vacuum filter needs to be cleaned with a cleaning device to remove residual materials.

[0003] For example, announcement number CN221673645U (titled "A Material Removal Device for the Discharge Tank of a Disc Vacuum Filter") includes a mounting frame slidably connected to the discharge trough, which is located within the inner cavity of the disc vacuum filter. The discharge trough has a connecting groove on its side wall. A connecting frame passing through the connecting groove is fixedly connected to the side wall of the mounting frame. A drive mechanism is fixedly mounted on the side wall of the disc vacuum filter, and the drive mechanism is kinetically connected to the connecting frame. A scraping assembly is fixedly mounted on the side wall of the mounting frame. The drive mechanism includes a first mounting plate and a second mounting plate, which are respectively fixedly mounted on the side wall of the disc vacuum filter. The first and second mounting plates rotate between each other. A drive screw is connected to the connecting frame, and the drive screw is connected to the connecting frame. A first motor is embedded in the side wall of the first mounting plate, and the output end of the first motor is fixedly connected to the end of the drive screw. The drive mechanism mounted on the side wall of the disc vacuum filter drives the connecting frame and the mounting frame to reciprocate inside the discharge trough, so that the scraper in the scraping assembly continuously removes the material in the discharge trough and moves it to the collection belt conveyor for outward transportation. This device can effectively prevent the material from sticking to the inner wall of the discharge trough, avoid the material from clogging in the discharge trough, improve the stability of the normal operation of the filter, and at the same time reduce the number of times the discharge trough needs to be maintained and cleaned manually, saving manpower.

[0004] The aforementioned cleaning device removes material from the discharge trough using a scraper assembly. However, the use of multiple scraper structures for material removal leads to excessively high costs and affects the normal operation of the disc vacuum filter. Therefore, we provide a material cleaning device for the discharge trough of a disc vacuum filter. Summary of the Invention

[0005] The purpose of this utility model is to provide a material removal device for the discharge trough of a disc vacuum filter, so as to solve the problem mentioned in the background art that the existing removal device removes the material in the discharge trough by setting up a scraping component, but sets up multiple scraper structures in order to remove the material, resulting in excessive material removal cost and affecting the normal use of the disc vacuum filter.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material removal device for a discharge trough of a disc vacuum filter, comprising a filter frame, a discharge trough being provided inside the filter frame, a guide frame being fixedly provided on one outer wall of the filter frame by screws, and a threaded screw being provided inside the guide frame.

[0007] Also includes:

[0008] The lead screw slider is movably set inside the guide frame by the threaded lead screw, and a support plate is set above the lead screw slider. A support rod is welded to the upper end of the support plate, and a crossbeam plate is welded to one side of the outer wall of the support rod. A telescopic hydraulic cylinder is set at the upper end of the crossbeam plate.

[0009] A movable seat plate is welded to one end of the piston rod of the telescopic hydraulic cylinder, and a bearing circular frame is provided below the movable seat plate, with a rotating shaft provided at the front end of the bearing circular frame.

[0010] The propeller rod is welded to the outer wall of the rotating shaft. There are three propeller rods, and the distance between two adjacent propeller rods is equal. A scraper is welded to one end of the propeller rod.

[0011] A guide rod is positioned on one side of the threaded screw. Both ends of the guide rod are welded to the inner walls of both ends of the guide frame. The threaded screw has a guide hole inside, through which the threaded screw is movably connected to the guide rod.

[0012] Preferably, a stop block is welded to the outer wall of the rear end of the support rod, and an extension rod is welded to the outer wall of one side of the movable seat plate. The movable seat plate abuts against the stop block through the extension rod.

[0013] Preferably, a connecting seat is welded to the upper end of the lead screw slider, and the two ends of the connecting seat are welded to the lead screw slider and the support plate, respectively.

[0014] Preferably, a drive motor is fixedly mounted on the rear end of the supporting circular frame by screws, and the drive motor is connected to the rotating shaft via a coupling.

[0015] Preferably, a servo motor is provided at one end of the guide frame, and the output shaft of the servo motor is connected to a threaded screw drive via a coupling.

[0016] Preferably, a connecting rod is provided at the connection position between the movable seat plate and the supporting circular frame, and the two ends of the connecting rod are welded to the movable seat plate and the supporting circular frame respectively.

[0017] Preferably, the outer wall of the scraper is provided with abrasive paper, and the abrasive paper is glued and fixed to the outer wall of the scraper.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses a servo motor to drive the threaded screw within the guide frame to rotate, which in turn drives the screw slider to move along the guide rod, simultaneously moving the support rod and crossbeam plate. During this movement, the rotating shaft reaches the position of each discharge trough. Then, a telescopic hydraulic cylinder lowers the movable seat plate until the extension rod abuts the stop block. At this point, the center point of the rotating shaft coincides with the center point of the discharge trough. The drive motor then drives the rotating shaft to rotate, causing the scraper plates at one end of the three paddle rods to perform rotating scraping of the material inside the discharge trough. One end is attached with abrasive paper, which is used to further brush away residual material. The abrasive paper is replaceable. After one discharge trough is cleaned, it moves to the next discharge trough to continue cleaning. This saves costs and does not affect the normal operation of the disc vacuum filter. It improves the efficiency of cleaning materials from the discharge trough of the disc vacuum filter. It overcomes the problem that existing cleaning devices use scraping components to clean materials in the discharge trough, but multiple scraper structures are set up to remove materials, resulting in excessive cleaning costs and affecting the normal operation of the disc vacuum filter.
