Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically to a sewage treatment machine with an adjustable filter cloth working angle. Background Technology

[0002] In wastewater filtration, the use of inclined filter conveyor belts to filter and transport impurities in water is widely applied. This technology separates wastewater from impurities by intercepting impurities in the wastewater and sending them out of the treatment area.

[0003] However, in practical applications, it has been found that the lifting and conveying performance of the filter conveyor belt significantly decreases when round or oval impurities are present in the wastewater. These types of impurities are difficult to transport effectively by the filter, tending to roll or slide on the filter surface, preventing them from being smoothly lifted and conveyed by the conveyor belt. Their accumulation and continuous friction with the filter conveyor belt not only reduce filtration efficiency and affect equipment operation, but also accelerate the wear of the filter conveyor belt, significantly shortening its service life and increasing equipment maintenance costs and replacement frequency.

[0004] Therefore, it is necessary to propose a wastewater treatment machine with an adjustable filter cloth working angle to solve the above problems. Utility Model Content

A movable frame driven by a screw is slidably connected to the filter tank. A connecting rod is provided between the movable frame and the rotating support.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-3 As shown, a wastewater treatment machine with an adjustable filter cloth working angle includes a filter tank 2. A filter cloth conveyor belt 5 is inclinedly arranged inside the filter tank 2. A drive roller 15 and a driven roller 16 are respectively provided on the inner sides of both ends of the filter cloth conveyor belt 5. The drive roller 15 is rotatably connected to the filter tank 2, and the driven roller 16 is driven to rise and fall by an adjusting mechanism 1 to adjust the inclination angle of the filter cloth conveyor belt 5. The adjusting mechanism 1 includes a rotating bracket 12 arranged along the filter cloth conveyor belt 5. One end of the rotating bracket 12 near the drive roller 15 is rotatably connected to the filter tank 2, and the driven roller 16 is rotatably connected to the other end of the rotating bracket 12. A movable frame 8, driven by a screw 10, is slidably connected to the filter tank 2. A connecting rod 9 is provided between the movable frame 8 and the rotating bracket 12, and both ends of the connecting rod 9 are rotatably connected to the movable frame 8 and the rotating bracket 12, respectively. Specifically, the movable frame 8 is slidably connected to the frame of the filter tank 2 via a grooved wheel, the screw 10 is rotatably connected to the filter tank 2, and the screw 10 is threadedly connected to the movable frame 8. The drive roller 15 is driven by a motor 4.

[0026] When the tilt angle of the filter cloth conveyor belt 5 needs to be adjusted, the movable frame 8 is driven to slide along the edge of the filter tank 2 by rotating the screw 10. During the movement, the movable frame 8 drives the free end of the rotating support 12 to rotate through the connecting rod 9, thereby driving the rotating support 12 to rise and fall, thus adjusting the tilt angle of the filter cloth conveyor belt 5. This adjusts the climbing ability of the filter cloth conveyor belt 5 to carry filter residue, solving the problem of filter residue accumulation; at the same time, it can adjust the effective filtration area of ​​the filter cloth conveyor belt 5. The larger its tilt angle and the longer its length immersed below the liquid surface, the larger the effective filtration area.

[0027] To facilitate the collection and discharge of filter residue, a screw conveyor 19 is installed below the top of the filter cloth conveyor belt 5. A scraper 18 is fixedly connected to one side of the screw conveyor 19, and a slag discharge pipe 20 is connected to the discharge end of the screw conveyor 19. When the filter cloth conveyor belt 5 moves to the scraper 18, the filter residue is scraped off into the screw conveyor 19 under the action of the scraper 18, and then sent out through the slag discharge pipe 20 via the screw conveyor 19.

[0028] To prevent the adjustment of the tilt angle of the filter cloth conveyor belt 5 from affecting its tensioning effect, a reversing roller 14 is provided at the rotatable connection between the rotating bracket 12 and the filter tank 2 to support the filter cloth conveyor belt 5. The reversing roller 14 is rotatably connected to the filter tank 2. Under the limiting support of the reversing roller 14, the filter cloth conveyor belt 5 is prevented from becoming loose due to the lifting adjustment of the driven roller 16. Preferably, the scraper 18 is located between the reversing roller 14 and the driving roller 15 to prevent the adjustment of the tilt angle of the filter cloth conveyor belt 5 from changing the gap between the scraper 18 and the surface of the filter cloth conveyor belt 5, thus affecting the filter residue scraping effect.

[0029] To prevent the filter cloth conveyor belt 5 from sagging, several rollers 13 for supporting the filter tank 2 are fixedly connected to the rotating bracket 12.

[0030] Specifically, the filter cloth conveyor belt 5 divides the filter tank 2 into two chambers. The chamber above the filter cloth conveyor belt 5 is connected to the water inlet 7, and the chamber below the filter cloth conveyor belt 5 is provided with a drain trough 21, one end of which is connected to a drain outlet 6.

[0031] During wastewater treatment, wastewater is introduced into the filter tank 2 through the inlet 7. Under the action of the filter cloth conveyor belt 5, impurities in the wastewater are filtered out. After filtration, the wastewater flows into the drain tank 21 and is discharged from the drain outlet 6.

[0032] To ensure filtration effectiveness, a sealing assembly 3 is fixedly connected to the rotating support 12. The sealing assembly 3 includes an upper clamping plate 22, an elastic sealing plate 23, and a lower clamping plate 24. The lower clamping plate 24 is fixedly connected to the rotating support 12. The elastic sealing plate 23 is clamped and fixed by the upper clamping plate 22 and the lower clamping plate 24. The two sides of the elastic sealing plate 23 are respectively attached to the inner wall of the filter tank 2 and the surface of the filter cloth conveyor belt 5 to seal the gap between the filter tank 2 and the filter cloth conveyor belt 5. Specifically, the liquid level in the filter tank 2 should be within the height range of the effective sealing area of ​​the sealing assembly 3. By sealing the gap between the filter tank 2 and the filter cloth conveyor belt 5 with the elastic sealing plate 23, the filtration failure problem caused by sewage bypass can be effectively solved. At the same time, the elastic sealing plate 23 prevents filter residue from falling into the chamber below the filter cloth conveyor belt 5.

[0033] Because the elastic sealing plate 23 is clamped and fixed to the rotating bracket 12 by the cooperation of the upper clamping plate 22 and the lower clamping plate 24, it can move with the filter cloth conveyor belt 5 when the inclination is adjusted, so as to meet the sealing requirements of different inclination angles. Preferably, the inner wall of the filter tank 2 corresponding to the free end of the rotating bracket 12 is inclined, so as to effectively reduce the range of change of the distance between the inner wall of the filter tank 2 and the rotating bracket 12 during the adjustment of the filter cloth conveyor belt 5.

[0034] To facilitate the cleaning of sediments accumulated at the bottom of filter tank 2, a drain pipe 17 is connected to one side of the bottom of filter tank 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
