DETAILED DESCRIPTION

[0019] See also Figure 1-4 A sludge discharge device for a sewage treatment sedimentation tank comprises a sludge pump 1 and a conduit 4, wherein the sludge pump 1 is fixedly connected to a displacement mechanism 2 through the conduit 4, a cleaning mechanism 3 is fixedly installed on one side of the displacement mechanism 2, the cleaning mechanism 3 comprises a cleaning tank 301, a plurality of filter plates 302 are fixedly installed inside the cleaning tank 301, a first mounting frame 303 is rotatably installed inside the cleaning tank 301, a second mounting frame 304 is rotatably installed inside the first mounting frame 303, a plurality of cleaning teeth 305 are fixedly installed on the surface of the second mounting frame 304, the cleaning teeth 305 are staggeredly installed on one side of the filter plate 302, and a collecting box 306 is fixedly installed on the top of the cleaning tank 301;

[0020] During use, the cleaning mechanism 3 is driven to move inside the sedimentation tank by the displacement mechanism 2, and the first mounting frame 303 drives the second mounting frame 304 to rotate and stir the sludge on one side of the sludge. At the same time, the sludge pump 1 generates negative pressure inside the cleaning tank 301 through the conduit 4, sucks in the stirred and dispersed sludge, and discharges it through the sewage outlet of the sludge pump 1. During this process, a number of filter plates 302 block large impurities to prevent blockage. At the same time, the rotating first mounting frame 303 drives a number of cleaning teeth 305 through the second mounting frame 304 to clean the surfaces of a number of filter plates 302. While preventing the filter plates 302 from being blocked, the impurities on the surface of the first mounting frame 303 are thrown into the collection box 306 for collection. In summary, the present device has the advantage of collecting large impurities and preventing blockage during the sludge discharge process, thereby solving the problem that a large number of large impurities are more likely to exist in large sedimentation tanks, blocking the sludge discharge device and interrupting the sludge discharge operation.

[0021] Furthermore, a plurality of mounting plates 308 are fixedly installed inside the first mounting frame 303, a buffer rod 309 is fixedly installed on one side of the mounting plate 308, and one end of the buffer rod 309 away from the mounting plate 308 is rotatably installed on one side of the second mounting frame 304;

[0022] During use, after the cleaning teeth 305 and the second mounting frame 304 come into contact with hard objects, they will rotate on one side of the first mounting frame 303 under the action of stress. During this process, the buffer rod 309 is deformed between the mounting plate 308 and the second mounting frame 304, buffering the second mounting frame 304 and preventing the cleaning teeth 305 and the second mounting frame 304 from being damaged by hard contact with impurities.

[0023] Further, the displacement mechanism 2 includes a displacement chassis 201, a first connection port 202 is provided on the top of the displacement chassis 201, a second connection port 203 is opened on the displacement chassis 201, the second connection port 203 is fixedly connected to one side of the cleaning tank 301 through the conduit 4, and the first connection port 202 is fixedly connected to one side of the sludge pump 1 through the conduit 4;

[0024] During use, the displacement chassis 201, the sludge pump 1, and the cleaning tank 301 are interconnected through the first connection port 202, the second connection port 203, and the conduit 4, and at the same time, the conduit 4 plays a certain fixing role to prevent the sludge pump 1 from being directly connected to the cleaning tank 301 through the conduit 4. The conduit 4 has too high a degree of freedom and is entangled on the surface of the displacement mechanism 2 during displacement.

[0025] Furthermore, a plurality of counterweight blocks 204 are movably installed on the top of the displacement chassis 201, a connecting rope 206 is fixedly connected to the top of the displacement chassis 201, and a floating ball 207 is fixedly connected to the top of the connecting rope 206;

[0026] During use, a certain number of counterweights 204 are installed to increase the overall weight of the displacement mechanism 2, so that the displacement chassis 201 and the cleaning mechanism 3 can be displaced close to the hard surface in the sedimentation tank to ensure mud discharge efficiency. During underwater operations, the connecting rope 206 is used to ensure that the float 207 vertically displaces the top of the chassis 201 and floats on the water surface, so that the staff can understand the position of the displacement chassis 201 on the bottom of the water through the water surface, which is convenient for operations.

[0027] Furthermore, a protective plate 205 is fixedly installed at the bottom of the displacement chassis 201;

[0028] During use, the protective plate 205 is used to prevent hard objects at the bottom from scratching the bottom of the displacement bottom plate 201 .

[0029] Furthermore, the displacement chassis 201 is specifically a wire-controlled crawler chassis;

[0030] During use, the staff controls the displacement of the displacement chassis 201 inside the sedimentation tank through the connecting line, and the use of the crawler chassis can ensure the displacement capability of the displacement chassis 201 on a complex plane.

[0031] Furthermore, the sludge pump 1 is specifically a screw sludge pump, and a motor 307 is fixedly installed on one side of the cleaning tank 301;

[0032] During use, the second mounting frame 304 is driven to rotate by the motor 307, and the sludge pump 1, which is specifically a screw sludge pump, has the advantage of being insensitive to the incoming gas and dirt, ensuring that it can still work stably when the sludge has a high gas content or contains solid particles, and will not cause a significant drop in work efficiency due to sudden changes in gas or particles.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
