Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a pool bottom cleaning device for wastewater treatment. Background Technology

[0002] Electroplating wastewater refers to all types of wastewater generated during the electroplating process. It typically contains high concentrations of heavy metal ions (such as chromium, nickel, copper, and zinc), acids and alkalis, cyanides, organic additives, and other chemical substances. This wastewater is characterized by high toxicity, complex composition, dark color, and extreme pH values. Direct discharge without treatment will cause serious harm to the environment and human health. Therefore, electroplating wastewater must undergo strict treatment to meet environmental emission standards before it can be discharged or utilized for resource recovery.

[0003] In current traditional electroplating wastewater treatment practices, the cleaning of the bottom of the wastewater tank usually relies on manual rinsing and other methods. This method not only requires operators to invest a lot of time and labor, but also poses a high safety risk during operation because it requires direct contact with harmful substances and potentially toxic gases. Utility Model Content

[0004] One objective of this invention is to provide a wastewater treatment tank bottom cleaning device. This invention addresses the problem mentioned in the background that in current traditional electroplating wastewater treatment practices, the cleaning of wastewater tank bottoms usually relies on manual rinsing and other methods. This method not only requires operators to invest a lot of time and labor, but also poses a high safety risk during operation due to direct contact with harmful substances and potentially toxic gases.

[0005] A wastewater treatment pool bottom cleaning device according to an embodiment of the present utility model includes a moving mechanism installed on the upper part of a wastewater pool for driving a flushing mechanism and a cleaning mechanism to move, and a cleaning mechanism installed in the lower part of the wastewater pool for cleaning the pool bottom. The moving mechanism includes a first slider, which is slidably connected to the upper part of the wastewater pool. The cleaning mechanism includes a connecting block, a bucket, and rollers. The bucket is movably connected to the lower part of the wastewater pool through the connecting block. The rear side of the bucket is movably connected to the rollers through a fixing block. A connecting rod is fixedly connected to the upper surface of the bucket. A clamp is rotatably connected to the inner side of the connecting rod through a rotating shaft. A swing rod is fixedly connected to the side surface of the rotating shaft. The surface of the rollers is movably connected to one end of a first transmission rod. The other end of the first transmission rod is movably connected to the surface of the swing rod through a second transmission rod.

[0006] Preferably, a connecting plate is fixedly connected to the side surface of the connecting rod, and a spring for realizing the return of the swing rod is installed between the upper surface of the connecting plate and the side surface of the swing rod.

[0007] Preferably, the bucket is fixedly connected to the lower part of the first slider by a connecting block, and the connecting block is in close contact with the inner wall surface of the wastewater tank.

[0008] Preferably, a drive motor is fixedly connected to one side surface of the wastewater pool, a sliding groove is provided on the upper surface of the wastewater pool, and a screw is driven to the output end of the drive motor.

[0009] Preferably, the rinsing mechanism includes a water tank and a high-pressure nozzle. A second slider is fixedly connected to the lower surface of the water tank, and the high-pressure nozzle is fixedly connected to the inside of the clamp. The high-pressure nozzle and the water tank are interconnected by a water supply pipe.

[0010] Preferably, both the first slider and the second slider are threadedly connected to the surface of the screw, and the rotation of the screw drives the first slider and the second slider to slide synchronously in the same direction.

[0011] Preferably, the wastewater pool has an inlet and an outlet on its side surface.

[0012] The beneficial effects of this utility model are:

[0013] This utility model, through its cleaning mechanism, allows for automatic cleaning of the bottom of the wastewater tank when cleaning is required. The bucket slides along the bottom of the tank, simultaneously driving rollers to roll. A first and second transmission rod on the roller surface pulls a swing arm that swings up and down above the bucket. This causes a high-pressure nozzle, fixed to the rotating shaft by clamps, to swing up and down, performing high-pressure rinsing on different areas of the wastewater tank bottom. Impurities adhering to the bottom of the wastewater tank are collected by the bucket. Simultaneously, the movement of the bucket causes a connecting block to clean the inner wall of the wastewater tank. This achieves automatic cleaning of the bottom and inner wall of the wastewater tank, improving cleaning efficiency while ensuring the hygiene and ease of maintenance of the wastewater tank.

[0014] This utility model features a flushing mechanism and a moving mechanism. A drive motor rotates a screw, causing the first slider to slide on the upper surface of the wastewater tank. This, in turn, moves the cleaning mechanism below. Simultaneously, the screw causes the second slider and the first slider to slide synchronously, ensuring that the water tank remains above the cleaning mechanism. This provides a water source for the high-pressure nozzles, avoiding the inconvenience of manual cleaning. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-4A wastewater treatment tank bottom cleaning device includes a moving mechanism 4 installed on the upper part of a wastewater tank 1 for moving a flushing mechanism 5 and a cleaning mechanism 6, and a cleaning mechanism 6 installed in the lower part of the wastewater tank 1 for cleaning the tank bottom. The moving mechanism 4 includes a first slider 404 slidably connected to the upper part of the wastewater tank 1. The cleaning mechanism 6 includes a connecting block 602, a bucket 601, and rollers 604. The bucket 601 is movably connected to the lower part of the wastewater tank 1 via the connecting block 602. The rollers 604 are movably connected to the rear side of the bucket 601 via a fixing block 603. A connecting rod 607 is fixedly connected to the upper surface of the bucket 601. A clamp 609 is rotatably connected to the inner side of the connecting rod 607 via a rotating shaft 608. A swing rod 610 is fixedly connected to the side surface of the rotating shaft 608. The surface of the rollers 604 is movably connected to one end of a first transmission rod 605. The other end of 05 is movably connected to the surface of the swing rod 610 via the second transmission rod 606. When the bottom of the wastewater pool 1 needs to be cleaned, the bucket 601 slides on the bottom of the pool. While the bucket 601 is sliding, it drives the roller 604 to roll on the bottom of the pool. The first transmission rod 605 and the second transmission rod 606 on the surface of the roller 604 pull the swing rod 610 to swing up and down on the upper part of the bucket 601. This causes the high-pressure nozzle 504, which is fixed to the surface of the rotating shaft 608 by the clamp 609, to swing up and down, performing high-pressure rinsing on different positions of the bottom of the wastewater pool 1. Impurities adhering to the bottom of the wastewater pool 1 are collected by the bucket 601. At the same time, the movement of the bucket 601 causes the connecting block 602 to clean the inner wall of the wastewater pool 1. This realizes automatic cleaning of the bottom and inner wall of the wastewater pool 1, improves cleaning efficiency, and ensures the hygiene and ease of maintenance of the wastewater pool 1.

[0023] Example 1: A connecting plate 611 is fixedly connected to the side surface of the connecting rod 607. A spring 612 for resetting the swing rod 610 is installed between the upper surface of the connecting plate 611 and the side surface of the swing rod 610. The bucket 601 is fixedly connected to the lower part of the first slider 404 through the connecting block 602. The connecting block 602 is in close contact with the inner wall surface of the wastewater tank 1. A drive motor 401 is fixedly connected to one side surface of the wastewater tank 1. A sliding groove 402 is opened on the upper surface of the wastewater tank 1. The output end of the drive motor 401 is connected to a screw 403. The drive motor 401 drives the screw 403 to rotate, causing the first slider 404 to slide on the upper surface of the wastewater tank 1, thereby driving the cleaning mechanism 6 below to move. At the same time, the screw 403 causes the second slider 502 and the first slider 404 to slide synchronously, so that the water tank 501 is always above the cleaning mechanism 6, providing a water source for the high-pressure nozzle 504 and avoiding the inconvenience of manual cleaning.

[0024] Example 2: The flushing mechanism 5 includes a water storage tank 501 and a high-pressure nozzle 504. A second slider 502 is fixedly connected to the lower surface of the water storage tank 501. The high-pressure nozzle 504 is fixedly connected to the inner side of the clamp 609. The high-pressure nozzle 504 and the water storage tank 501 are connected to each other through a water supply pipe 503. The clamp 609 is swung by the first transmission rod 605, the second transmission rod 606 and the swing rod 610, thereby driving the high-pressure nozzle 504 to swing up and down to flush and clean different positions on the bottom of the wastewater pool 1. The first slider 404 and the second slider 502 are both threadedly connected to the surface of the screw 403. The rotation of the screw 403 drives the first slider 404 and the second slider 502 to slide synchronously and in the same direction. The side surface of the wastewater pool 1 is provided with a water inlet 2 and a drain outlet 3.

[0025] In use, the drive motor 401 starts, and the screw 403, which is connected to the output end, rotates in the slide groove 402, thereby driving the first slider 404 to slide on the upper surface of the wastewater tank 1. At the same time, the second slider 502 is also threadedly connected to the screw 403 and slides synchronously and in the same direction as the first slider 404, ensuring that the water tank 501 is always above the cleaning mechanism 6, providing a continuous water source for the high-pressure nozzle 504. The bucket 601 is fixedly connected to the lower part of the first slider 404 by the connecting block 602 and is in close contact with the inner wall surface of the wastewater tank 1. As the first slider 404 moves, the connecting block 602 cleans the impurities adhering to the inner wall of the wastewater tank 1. The bucket 601 is at the bottom of the tank. The sliding motion simultaneously drives the roller 604 to roll. The first transmission rod 605 and the second transmission rod 606 on the surface of the roller 604 pull the swing rod 610 as the roller 604 rolls. This causes the clamp 609, which is rotatably connected to the inner side of the connecting rod 607 via the rotating shaft 608, to drive the high-pressure nozzle 504 to swing up and down on the upper part of the bucket 601, performing high-pressure rinsing on the bottom of the wastewater pool 1. The spring 612 ensures that the swing rod 610 can return to its original position during the rinsing process. During the cleaning process, the bucket 601 collects impurities from the bottom of the pool. The water inlet 2 and the drain outlet 3 on the side of the wastewater pool 1 are used for water intake and drainage of the cleaned wastewater, respectively. The entire process achieves automatic and efficient cleaning of the bottom and inner wall of the wastewater pool 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
