[0002] The flotation tank is a tank that mainly uses a large number of microbubbles to capture and adsorb small particles of adhesives to make them float, achieving the effect of solid-liquid separation.

[0003] The cited Chinese patent number is CN219950567U, which discloses a weight mechanism for a flotation tank scraper, which relates to the technical field of flotation tanks, including a cylindrical weight body, a dumbbell-shaped long hole is formed through the center of the weight body along the axial direction, a long axis is arranged in the long hole, the long hole includes a long axis hole in the middle, a bearing hole connecting the two ends of the long axis hole, a bearing is arranged in the bearing hole, the bearing is sleeved on the long axis, the length of the long axis is greater than the length of the weight body, one end of the long axis is fixedly connected to a support rod, the support rod is arranged perpendicular to the long axis, and the support rod is fixedly connected to the scraper;

[0004] During the operation of the scraper of the flotation tank, the heavy hammers at both ends of the scraper flip up and down, driving the scraper to automatically scrape away the tar residue and foam on the surface of the flotation tank. However, due to the excessive friction of the heavy hammers at both ends of the scraper during operation, the scraper cannot flip normally, causing the scraper to deform and get stuck, shortening the service life of the scraper, and increasing the maintenance workload and repair cost of the scraper. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a weight mechanism for a flotation tank scraper to solve the problems raised in the above background technology.

One side of the fan blade leaks out, and the other side of the fan blade will be impacted by the water flow. The fan blade is driven to rotate under the impact of the water flow. The fan blade will drive the rotation of the impact rod during the rotation process. When the rotation hits the inner wall of the flotation tank, the weight device will be squeezed away from the inner wall of the flotation tank, thereby reducing the friction between the weight device and the inner wall of the flotation tank, thereby extending the service life of the weight device.

[0018] The present invention provides a weight hammer mechanism for a flotation tank scraper. It has the following beneficial effects:

[0019] 1. The weight mechanism of the flotation tank scraper is arranged in front of the weight device through an inclined plate. When the weight device moves toward the inclined plate, the water flow in the flotation tank impacts the inclined plate, and the inclined direction of the inclined plate is squeezed by the water, and then the weight device is moved toward the direction of the toggle plate, thereby preventing the weight device from rubbing against the inner wall of the flotation tank. The friction between the weight device and the inner wall of the flotation tank is avoided by utilizing the squeezing of the water flow. Under the water flow squeezed by the first pressing plate and the second pressing plate, the water flow will also impact toward the inclined plate, thereby reducing the contact between the weight device and the inner wall of the flotation tank and extending the service life of the weight device.

[0020] 2. The flotation tank scraper uses a heavy hammer mechanism, which utilizes water flowing into the installation hole. The water flows on both sides of the elastic cloth. The guide plate can be installed by setting the elastic cloth. The guide plate partially intercepts the water. The heavy hammer device is pulled by the elastic cloth under the impact of the water flow, and then the heavy hammer device is kept away from the inner wall of the flotation tank, thereby protecting the heavy hammer device.

[0021] 3. The flotation tank scraper uses a weight mechanism, which utilizes the kinetic energy generated by the movement of the weight device in the water of the flotation tank to drive the follow-up movement of the fan blades. The fan blades are arranged on the outer wall of the weight device through the second bearing. One side of the fan blades leaks out, and the other side of the fan blades will be impacted by the water flow. The impact of the water flow drives the fan blades to rotate. The fan blades will drive the rotation of the impact rod during the rotation process. When the rotation hits the inner wall of the flotation tank, the weight device will be squeezed away from the inner wall of the flotation tank, thereby reducing the friction between the weight device and the inner wall of the flotation tank, thereby extending the service life of the weight device.

[0022] 4. The weight mechanism of the flotation pool scraper is sealed on the inner wall of the telescopic rod and the placement hole by the waterproof layer to prevent the water in the flotation pool from leaking out. The elastic material of the waterproof layer ensures that the waterproof layer can flexibly squeeze the water. The squeezing of the first pressure plate and the second pressure plate causes the water flow in the flotation pool to move toward the direction of the weight device. The water flow impacts the weight device and the inclined plate, so that the weight device is away from the position of the inner wall of the flotation pool, which plays a protective effect on the weight device. The width of the limit block makes the weight device have a certain buffer distance when the weight device moves toward the placement hole, thereby avoiding the friction between the weight device and the inner wall of the flotation pool, which plays a protective effect on the weight device.

[0038] A connecting frame 72, the connecting frame 72 is fixedly connected to the outer wall of the weight device 9;

[0039] The inclined plate 73 is fixedly connected to the outer wall of the connecting frame 72 .

[0040] An elastic cloth 75 is fixedly connected to the outer wall of the inclined plate 73 , and the elastic cloth 75 passes through the mounting hole 71 .

[0041] The outer wall of the elastic cloth 75 is fixedly connected with a guide plate 76 , and the outer wall of the weight device 9 is fixedly connected with a second bearing 74 .

[0042] The inner wall of the second bearing 74 is rotatably connected with a fan blade 77 , and the top of the fan blade 77 is fixedly connected with a striker rod 78 , which is in active contact with the inner wall of the air flotation tank 1 .

[0043] The outer wall of the air flotation tank 1 is fixedly connected with a second bracket 12 , the outer wall of the second bracket 12 is fixedly connected with a motor 13 , and the motor 13 is fixedly connected with the gear 4 via a rotating shaft.

[0044] When in use, the motor 13 is powered on and started to drive the gear 4 to rotate. The gear 4 is set on the first bearing 3, and the four first bearings 3 are then installed on the four gears 4. When the gear 4 rotates, it drives the conveyor chain 5 to rotate. During the rotation process, the conveyor chain 5 drives the toggle plate 6 to rotate. When the toggle plate 6 is located on the flotation tank 1 and moves, the floating foam on the flotation tank 1 is scraped off. Then, after the floating foam moves to the position of the guide groove 2, it guides the flow through the guide groove 2. The inclined plate 73 is set in the front position of the weight device 9. Then, when the weight device 9 moves in the direction of the inclined plate 73, the inclined plate 73 is obliquely set in the direction of the flotation tank 1. Then, when the water flow in the flotation tank 1 hits the inclined plate 73, the oblique direction of the inclined plate 73 will be squeezed by the water, and then the weight device 9 is moved in the direction of the toggle plate 6, thereby preventing the weight device 9 from contacting the flotation tank 1. The inner wall of the air flotation pool 1 rubs against the weight device 9. When the weight device 9 moves, the water in the air flotation pool 1 will flow into the mounting hole 71, and then the water will flow on both sides of the elastic cloth 75.

When it rotates and impacts the inner wall of the air flotation pool 1, it will squeeze the weight device 9 away from the inner wall of the air flotation pool 1.

[0047] The outer wall of the air flotation tank 1 is fixedly connected to a first bracket 11 , and the outer wall of the first bracket 11 is fixedly connected to a telescopic machine 10 .

[0048] The outer wall of the air flotation tank 1 is fixedly connected with a squeezing mechanism 8 , which includes a placement hole 88 . The placement hole 88 is opened on the outer wall of the air flotation tank 1 , and the inner wall of the placement hole 88 is fixedly connected with a limiting block 86 .

[0049] The outer wall of the telescopic machine 10 is movably connected with a telescopic rod 83, the outer wall of the telescopic rod 83 is fixedly connected with a first pressure plate 82, the outer wall of the telescopic rod 83 is fixedly connected with a waterproof layer 81, the waterproof layer 81 is fixedly connected to the inner wall of the placement hole 88, a sleeve rod 85 is sleeved on the right side of the telescopic rod 83, a spring 84 is fixedly connected between the sleeve rod 85 and the telescopic rod 83, and a second pressure plate 87 is fixedly connected to the right side of the sleeve rod 85, and the second pressure plate 87 is inserted into the placement hole 88.

[0050] When in use, the telescopic machine 10 is powered on to start the telescopic rod 83 to extend and retract, and the waterproof layer 81 is sealed on the inner wall of the telescopic rod 83 and the placement hole 88 to prevent the water in the flotation pool 1 from leaking out. The limit block 86 is limited to the inner wall of the placement hole 88, thereby preventing the second pressure plate 87 from moving into the flotation pool 1. When the telescopic rod 83 drives the first pressure plate 82 and the second pressure plate 87 to move toward the flotation pool 1, the squeezing of the first pressure plate 82 and the second pressure plate 87 causes the water flow in the flotation pool 1 to move toward the direction of the heavy hammer device 9, and the impact of the water flow The weight device 9 is struck away from the inner wall of the flotation tank 1. The width of the limit block 86 causes the weight device 9 to move toward the placement hole 88. The width of the limit block 86 causes the weight device 9 to have a certain buffer distance, thereby avoiding the friction between the weight device 9 and the inner wall of the flotation tank 1. The spring 84 is arranged between the sleeve rod 85 and the telescopic rod 83. The spring 84 is made of elastic material. The buffering of the spring 84 causes the second pressure plate 87 to squeeze the second pressure plate 87 to move even when it collides with the weight device 9.

The four first bearings 3 then install the four gears 4. When the gear 4 rotates, it drives the conveyor chain 5 to rotate. During the rotation process, the conveyor chain 5 drives the rotation of the toggle plate 6. When the toggle plate 6 is located on the flotation tank 1 and moves, the floating foam on the flotation tank 1 is scraped off. Then, after the floating foam moves to the position of the guide groove 2, it guides the flow through the guide groove 2. The inclined plate 73 is set in front of the heavy hammer device 9. Then, when the heavy hammer device 9 moves in the direction of the inclined plate 73, the inclined plate 73 is set obliquely in the direction of the flotation tank 1. Then, the water flow in the flotation tank 1 impacts When the weight device 9 reaches the inclined plate 73, the inclined direction of the inclined plate 73 will be squeezed by the water, and then the weight device 9 will move toward the direction of the toggle plate 6, thereby preventing the weight device 9 from rubbing against the inner wall of the flotation tank 1. During the movement of the weight device 9, the water in the flotation tank 1 will flow into the mounting hole 71, and then the water flow will flow on both sides of the elastic cloth 75, and then the guide plate 76 will partially intercept the water. Therefore, when the elastic cloth 75 is pulled by the guide plate 76, the weight device 9 is pulled by the elastic cloth 75, and then the weight device 9 is away from the inner wall of the flotation tank 1. When the weight device 9 is located in the water of the flotation tank 1 and moves, the fan blade 77 is arranged on the outer wall of the weight device 9 through the second bearing 74. One side of the fan blade 77 leaks out, and the other side of the fan blade 77 will be impacted by the water flow. The impact of the water flow drives the fan blade 77 to rotate. During the rotation process, the fan blade 77 drives the rotation of the impact rod 78. The impact rod 78 is made of elastic material. When it rotates and hits the inner wall of the flotation tank 1, it squeezes the heavy hammer device 9 away from the inner wall of the flotation tank 1. The telescopic machine 10 is powered on to drive the telescopic rod 83 to extend and retract. The waterproof layer 81 is sealed on the inner wall of the telescopic rod 83 and the placement hole 88 to prevent water in the flotation tank 1 from leaking out. The limit block 86 is limited to the inner wall of the placement hole 88, thereby preventing the second pressure plate 87 from moving into the flotation tank 1. The telescopic rod 83 drives the first pressure plate 82 and the second pressure plate 87 toward When moving in the flotation pool 1, the squeezing of the first pressure plate 82 and the second pressure plate 87 causes the water flow in the flotation pool 1 to move toward the direction of the heavy hammer device 9. Under the impact of the water flow, the heavy hammer device 9 is moved away from the inner wall of the flotation pool 1. The width of the limit block 86 causes the heavy hammer device 9 to move toward the placement hole 88. The width of the limit block 86 further allows the heavy hammer device 9 to have a certain buffer distance, thereby avoiding the friction between the heavy hammer device 9 and the inner wall of the flotation pool 1. The spring 84 is arranged between the sleeve rod 85 and the telescopic rod 83. The spring 84 is made of elastic material. Under the buffering of the spring 84, even when the second pressure plate 87 collides with the heavy hammer device 9, it will squeeze the second pressure plate 87 to move.
