Description

Technical Field

[0001] The invention relates to the technical field of mud cleaning, in particular to a mud cleaning device for a horizontal flow tank. Background Art

[0002] In many fields such as sewage treatment and water supply treatment, advection tanks are widely used as an important water treatment structure. Advection tanks mainly rely on the principle of gravity sedimentation to slowly settle suspended particles in the water in the tank, thereby achieving the separation of water and impurities; however, as time goes by, a large amount of sludge will gradually accumulate at the bottom of the advection tank.

[0003] Existing mud cleaning equipment usually uses hydraulic equipment to drive the scraper to scrape the mud when cleaning the sludge. However, the hydraulic system has high requirements on the cleanliness of the oil and needs to be filtered and changed regularly. Otherwise, impurities can easily cause component failures. In addition, when oil leakage occurs, it is troublesome to find the leakage point and repair it. In addition, the equipment cost is high, which is not easy to promote.

[0004] In view of this, further optimization is made for the above problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a mud clearing device for a horizontal flow tank, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mud cleaning device for an advection tank, comprising an advection tank, a plurality of mud scrapers arranged at the bottom of the advection tank for mud cleaning, an auxiliary pipe for connecting the mud scrapers, and a driving assembly arranged on the side wall of the advection tank along a first direction and driving the mud scrapers to move through the auxiliary pipe; The driving assembly includes a protection box arranged on the side wall along the first direction, a gear plate arranged inside the protection box, a protrusion arranged at the right edge of the gear plate, and a power rod sleeved on the surface of the protrusion, the bottom end of the power rod passes through a slideway provided at the bottom of the protection box and is rotatably connected to one end of the auxiliary pipe along the first direction, a driving block is arranged on the top of the protection box, the output end of the driving block is fixedly connected to a coupling, and the left end of the coupling is connected to the left end of the gear plate through a sprocket assembly; A positioning rod is inserted into one end of the auxiliary pipe along the first direction, and the other end of the positioning rod is fixedly connected to the side of the advection tank. A sludge groove is opened at one end along the second direction and is used in conjunction with a scraper plate to collect sludge. Vertical plates are detachably connected between multiple scrapers.

[0007] The present invention has the following beneficial effects: The mud cleaning device for the advection tank abandons the traditional hydraulic equipment and adopts a driving assembly composed of a gear plate in a protective box, a bump, a power rod and a driving block connected by a sprocket assembly. This mechanical driving method does not require a complex hydraulic oil system, avoids component failure caused by oil cleanliness problems, does not require regular filtering and oil change, and greatly reduces maintenance costs and maintenance difficulties. Compared with the hydraulic system, the structure of the mechanical drive assembly of the advection tank cleaning device is relatively simple, the cost of parts is low, and the maintenance cost caused by oil leakage is reduced, so that the equipment cost of the entire mud cleaning device is greatly reduced, and it is more convenient to promote and apply; The mud cleaning device for a horizontal flow tank has a mud scraper connected to an auxiliary pipe through an auxiliary block, and a limit plate and a positioning screw are provided on the auxiliary block. This connection method is convenient for installation and disassembly of the mud scraper, and is convenient for replacement when the mud scraper is worn or damaged, and can ensure the connection stability between the mud scraper and the auxiliary pipe during operation, so as to ensure the normal operation of the mud scraping work. A plurality of mud scrapers are connected through vertical plates, so as to maintain the stability of the mud scraping. The mud scraper is designed in a triangular prism shape, which can effectively reduce the resistance in the mud scraping process. When it moves forward, it can push the mud, and when it moves backward, it can shovel the mud, so as to facilitate and quickly clean the mud. The mud cleaning device for a horizontal flow tank has an N-shaped rod arranged in a U-shaped frame, and the bottom end of the internal rotating rod has a cutting blade, and the rotating rod is meshed with the toothed layer on the bottom side of the U-shaped frame. When the N-shaped rod moves with the chain 2, the rotating rod drives the cutting blade to rotate, and can cut larger lumps of mud or debris that may be encountered during the mud scraping process, further improving the mud cleaning effect and avoiding blockage. The mud cleaning device for a horizontal flow tank has a gear plate in a protective box meshed with an auxiliary plate, and a gear cylinder on the auxiliary plate is connected to a second chain through a rack. When the driving block drives the gear plate to rotate, a series of linkage structures can be used to make the second chain drive an N-shaped rod to slide on a U-shaped frame, thereby realizing the coordinated operation of the mud scraping plate and the cutting blade, thereby improving the overall working efficiency of the mud cleaning device. The electric telescopic rod arranged on the top of the protective box can control the push cover at its output end, thereby adjusting the meshing state of the gear plate and the auxiliary plate, thereby realizing automatic control of different working modes of the mud cleaning device, and meeting the mud cleaning needs under different working conditions. The mud cleaning device for a horizontal flow tank comprises a U-shaped frame fixed on the sides of the front and rear ends of the horizontal flow tank and an N-shaped rod slidably mounted on the surface of the frame, which provides good guidance and support for the movement of the mud scraper, ensures that the mud scraper can run smoothly during the mud cleaning process, prevents the mud scraper from deflecting or shaking, and improves the stability of the mud cleaning effect.

[0011] See also Figures 1 to 9 The present invention provides a mud cleaning device for an advection tank; comprising an advection tank 1, a plurality of mud scrapers 2 arranged at the bottom of the advection tank 1 for mud cleaning, an auxiliary pipe 3 for connecting the mud scrapers 2, and a driving component arranged on the side wall of the advection tank 1 along a first direction and driving the mud scrapers 2 to move through the auxiliary pipe 3; like Figure 1-2As shown, a plurality of drainage pipes are provided at the side wall of the advection tank 1 along the second direction, so as to facilitate the discharge of sewage into the interior of the advection tank 1. A sludge tank 11 is provided at the bottom of the advection tank 1, close to the drainage pipe, so that impurities in the sewage can flow into the sludge tank 11 in advance, thereby reducing the accumulation on the bottom wall of the advection tank 1. In order to reduce the resistance of the scraper 2 when scraping mud, an auxiliary strip (stainless steel material) is fixedly connected to the inner bottom wall of the advection tank 1 and fits with the lower surface of the scraper 2. When the scraper 2 moves forward and backward, the resistance of the scraper can be reduced; Through the scraper blade 2 and the auxiliary pipe 3, with the cooperation of the driving component, the scraper blade 2 can be made to reciprocate back and forth. When the scraper blade 2 moves forward, the sludge at the bottom of the advection tank 1 can be pushed to be discharged into the sludge tank 11. When the scraper blade 2 moves backward, the sludge at the rear can be shoveled up and accumulated on the inclined surface of the scraper blade 2. When the scraper blade 2 moves backward again, the sludge accumulated on the inclined surface of the scraper blade 2 can be moved to the front of the scraper blade 2, so as to push the sludge to continue to be discharged into the sludge tank 11.

[0012] The driving assembly includes a protective box 4 arranged on the side wall along the first direction, a gear plate 5 arranged inside the protective box 4, a protrusion 6 arranged at the right edge of the gear plate 5, and a power rod 7 sleeved on the surface of the protrusion 6. The bottom end of the power rod 7 passes through a slideway opened at the bottom of the protective box 4 and is rotatably connected to one end of the auxiliary tube 3 along the first direction by a pin connection. A driving block 8 is provided on the top of the protective box 4. A coupling 9 is fixedly connected to the output end of the driving block 8. The left end of the coupling 9 is connected to the left end of the gear plate 5 through a sprocket assembly; the sprocket assembly includes a gear rod 16 fixedly connected to the left end of the coupling 9, a gear rod 2 17 fixedly connected to the center of the left side of the gear plate 5, and a chain 18 is provided on the surfaces of the gear rod 16 and the gear rod 2 17.

[0013] like Figure 1-4 As shown, a protective shell (shown in the figure, not numbered) is provided on the top of the protective box 4, and a driving block 8 (driven by an electric motor or a motor as a power source) is fixedly connected to the inside of the protective shell. A coupling 9 is provided at the output end of the driving block 8, which can effectively buffer and reduce shock, and protect the driving block 8 from overload; Among them, the top end of the chain 18 is located inside the protective shell and is meshed with the gear rod 16, the bottom end passes through the inner bottom wall of the protective shell and extends to the inside of the protective box 4, meshed with the gear rod 2 17, and the left end of the gear rod 16 is rotatably connected to the inner wall of the protective shell. When the driving block 8 is started, the gear plate 5 is driven to rotate with the cooperation of the gear rod 16, the chain 18 and the gear rod 2 17. Since the power rod 7 is mounted on the protrusion 6 on the side of the gear plate 5, the power rod 7 reciprocates back and forth. With the cooperation of the power rod 7 and the auxiliary pipe 3, the scraper plate 2 is synchronously driven to move back and forth, thereby scraping off the sludge at the bottom of the advection tank 1.

[0014] like Figure 3-4 As shown, the power rod 7 also includes a bracket arranged on the left side of the gear plate 5, a power rod 1 arranged on the right side of the gear plate 5 and connected to the protrusion 6, and a power rod 2 connected to the other end of the power rod 1 through a pin, and the other end of the power rod 2 is connected to the auxiliary pipe 3 through a pin; the top end of the bracket extends to the interior of the protective box 4, and the bottom end passes through the slideway opened at the bottom of the protective box 4. A limiting cylinder is provided on the surface of the bottom end of the bracket, and the power rod 2 is provided inside the limiting cylinder. The purpose of this arrangement is to maintain the stability of the power rod 2 when it moves back and forth.

[0015] A positioning rod 10 is inserted at one end of the auxiliary pipe 3 along the first direction, and the other end of the positioning rod 10 is fixedly connected to the side of the advection tank 1. A sludge groove 11 is opened at one end along the second direction and is used in conjunction with a scraper plate 2 to collect sludge. Vertical plates 12 are detachably connected between multiple scraper plates 2.

[0016] The positioning rod 10 also includes an auxiliary rod fixedly connected to its surface, which can maintain the stability of the positioning rod 10. Through the positioning rod 10, when the auxiliary tube 3 moves forward and backward, the auxiliary tube 3 can be stably kept moving forward and backward; In order to facilitate the cleaning of the sludge inside the sludge tank 11, a sludge extraction device (not shown in the figure) can be provided inside the sludge tank 11. When the sludge inside the sludge tank 11 reaches a certain amount, the sludge can be extracted from the sludge tank 11 for reuse. The existing scraper blades 2 are fixed by welding when being connected. Since the top of the scraper blade 2 is prismatic, the surface of the vertical plate 12 is provided with a groove adapted thereto. The scraper blade 2 is connected by a screw provided on the upper surface of the vertical plate 12. The purpose of such a setting is that when one of the scraper blades 2 is damaged, it can be easily disassembled and replaced later.

[0017] The scraper blade 2 is in the shape of a triangular prism and there are several of them, among which four scraper blades 2 are provided with an auxiliary block 13 in the middle part, and the auxiliary block 13 is fixed to the scraper blade 2 by welding, and the auxiliary tube 3 is clamped in the groove opened on the surface of the auxiliary block 13, and a limiting plate 14 is inserted on the upper surface of the auxiliary block 13, and a positioning screw 15 is threadedly connected on the upper surface of the limiting plate 14, and its bottom end passes through the limiting plate 14 and extends to the inside of the auxiliary tube 3, and the auxiliary tube 3 can be quickly fixed by the limiting plate 14 and the positioning screw 15, and it is convenient for later disassembly and replacement.

[0018] A U-shaped frame 19 is fixedly connected to the sides of the interior and front and rear ends of the advection pool 1, and an N-shaped rod 20 that can slide forward and backward is sleeved on the surface of the U-shaped frame 19. The two ends of the opening of the N-shaped rod 20 are buckled on the surface of the vertical plate 12. When the scraper 2 moves forward and backward, the stability of the scraper can be maintained. A toothed layer 21 is provided on the side of the bottom of the U-shaped frame 19, and a rotating rod 22 meshing with the toothed layer 21 is provided inside the N-shaped rod 20. A cutting piece 23 is provided on the surface of the bottom end of the rotating rod 22. A chain 24 is provided inside the U-shaped frame 19, and a slider 25 is fixedly connected to the surface of the chain 24. The bottom end of the slider 25 is fixedly connected to the N-shaped rod 20, and the top end extends to the slideway opened on the lower surface of the U-shaped frame 19. The stability of the movement of the chain 24 inside the slideway can be ensured by the slider 25.

[0019] In order to reduce the accumulation of sludge on the surface of the U-shaped frame 19, the top of the U-shaped frame 19 is set in a triangular shape, so that the sludge can automatically slide to the bottom of the advection tank 1. The top of the N-shaped rod 20 is provided with a sliding frame adapted to the U-shaped frame 19. When the sliding frame drives the N-shaped rod 20 to move, the sludge on the surface of the U-shaped frame 19 can be further cleaned.

[0020] like Figure 1 , 2 As shown in Figure 5, the two ends of the U-shaped frame 19 along the first direction and the second direction are respectively fixed to the side wall of the advection tank 1 by bolts. There are two U-shaped frames 19, one of which is arranged at one end of the U-shaped frame 19 along the first direction, and the other is arranged at one end of the U-shaped frame 19 along the second direction. When the N-shaped rod 20 moves back and forth, since the top of the rotating rod 22 is engaged with the toothed layer 21, the cutting blade 23 at its bottom end is synchronously driven to rotate, which can cut larger pieces of sludge and impurities in the sludge, thereby improving the mud cleaning effect, reducing blockage, and reducing the resistance of the scraper 2 when scraping mud.

[0021] An auxiliary plate 26 meshing with the gear plate 5 is provided inside the protective box 4, a gear cylinder 27 is inserted at the center of the upper surface of the auxiliary plate 26, a rack 28 is provided on the outer wall at the top of the gear cylinder 27, both ends of the chain 24 pass through the U-shaped frame 19 and extend to the inside of the protective box 4, one end of the chain 24 is wrapped around the outer wall of the gear cylinder 27, forming a closed shape with the other end, and meshing with the rack 28.

[0022] An electric telescopic rod 29 is provided on the top of the protective box 4. The output end of the electric telescopic rod 29 extends to the interior of the protective box 4, passes through the gear cylinder 27, and is fixedly connected with a push cover 30. The top of the push cover 30 is clamped on the lower surface of the auxiliary plate 26 and is sleeved on the surface of the gear cylinder 27. A sprocket 31 connected to the chain 24 is provided at the turning point inside the U-shaped frame 19. The sprocket 31 can reduce the resistance of the chain 24 during movement, reduce the wear on the chain 24, and increase its service life.

[0023] like Figure 3 , 5 As shown in FIGS. 6 and 9, when the auxiliary disk 26 is meshed with the gear disk 5, the auxiliary disk 26 is synchronously driven to rotate. Since the gear barrel 27 is inserted in the center of the auxiliary disk 26, it is synchronously driven to rotate. The rack 28 provided on the outer wall of the gear barrel 27 is meshed with the chain 24, so that the chain 24 rotates around the gear barrel 27. When the chain 24 moves around the gear cylinder 27, since the chain 24 is arranged inside the U-shaped frame 19 and is fixedly connected to the N-shaped rod 20 through the slider 25, the chain 24 synchronously drives the N-shaped rod 20 to slide on the surface of the U-shaped frame 19. When the N-shaped rod 20 moves forward and backward, the cutting blade 23 is synchronously driven to rotate, further improving the overall efficiency of the mud cleaning device. In order to meet the mud cleaning requirements under different working conditions, a pressure sensor (not shown in the figure) can be set on the surface of the scraper blade 2, and a control module (not shown in the figure) can be set on the top of the protective box 4. When the force applied to the scraper blade 2 during mud scraping is greater than the pressure value set by the pressure sensor, the pressure sensor sends an electrical signal to the control module, and the control module controls the movement of the electric telescopic rod 29, drives the auxiliary plate 26 and the gear plate 5 to be in meshing state through the push cover 30, and synchronously drives the N-shaped rod 20 to move, and uses the cutting blade 23 at the bottom thereof to cut the impurities in the sludge, so as to improve the efficiency of mud cleaning; When the force applied to the scraper blade 2 during scraping is less than the pressure value set by the pressure sensor, the electric telescopic rod 29 drives the auxiliary plate 26 and the gear plate 5 to be out of meshing state, thereby meeting the mud clearing requirements under different working conditions.

[0024] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0025] In the present invention, the working steps of the device are as follows: 1. When in use, the device is in the state of installation completion, such as Figure 1-2As shown, when the sludge at the bottom of the advection tank 1 needs to be cleaned, the driving block 8 is started, and the scraper blade 2 is driven to move forward and backward under the cooperation of the sprocket assembly, the gear plate 5, the power rod 7 and the auxiliary pipe 3, so as to scrape the sludge and make it fall into the sludge tank 11 for collection; 2. When there is a lot of sludge at the bottom of the advection tank 1, the electric telescopic rod 29 is started, so that the auxiliary plate 26 and the gear plate 5 are in a meshing connection state. When the auxiliary plate 26 rotates, the gear cylinder 27 is synchronously driven to rotate, so that the chain 24 rotates around the gear cylinder 27. When the chain 24 moves, it synchronously drives the N-shaped rod 20 to move forward and backward, and the cutting blade 23 at the bottom thereof is used to cut the larger block sludge or debris that may be encountered during the scraping process, so as to improve the sludge cleaning efficiency; 3. After the mud cleaning work is completed, close the driving block 8 and the electric telescopic rod 29.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
