Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a backwashing device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. Filtration is a common method in wastewater treatment, and backwashing aims to remove impurities trapped in the filter screen or filter plate. Over time, filter screens or plates in treatment devices may become clogged, necessitating frequent disassembly and washing. Some existing backwashing devices can only wash the filter plates in a static state, cannot change the washing angle, easily create dead zones, and cause water to splash everywhere during washing, making cleaning difficult for workers.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN214861843U discloses a backwashing device for a wastewater treatment apparatus. This device can rinse the filter plate during rotation and reduce rinsing dead zones. It also prevents the cleaning water from splashing everywhere and can collect the wastewater after cleaning, thus facilitating the cleaning work for workers.

[0004] However, when using this device, the filter plate (cylindrical) cannot be quickly fixed on the turntable. In addition, one filter plate must be cleaned before the other filter plate can be fixed, which reduces the rinsing efficiency. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-6 A backwashing device for wastewater treatment includes: a washing platform 1, on which a washing frame 11 is installed; a moving mechanism 2, installed on the washing platform 1, for moving a filter cartridge; a pair of rotating mechanisms 3, installed on the moving mechanism 2, for rotating the filter cartridge; a fixing mechanism 4, installed on the rotating mechanism 3, for quickly fixing the filter cartridge; a lifting mechanism 5, installed on the washing frame 11, for adjusting the height of the washing mechanism 6; and a washing mechanism 6, installed at the lower end of the lifting mechanism 5, for washing the filter cartridge.

[0025] The working principle of this utility model is as follows: In specific use, the filter cylinder is fixed on the rotating mechanism 3 by the fixing mechanism 4. Then, the filter cylinder is moved by the moving mechanism 2 to the lower end of the rinsing mechanism 6. Next, the lifting mechanism 5 moves the rinsing mechanism 6 down, so that the rinsing mechanism 6 is sleeved on the outside of the rotating mechanism 3. Then, the rotating mechanism 3 is started, and the filter cylinder is rotated by the rotating mechanism 3. The rinsing mechanism 6 can backwash the filter cylinder. At the same time, the filter cylinder to be rinsed can be fixed on another rotating mechanism 3 by the fixing mechanism 4, which facilitates the subsequent rinsing work and can effectively improve the rinsing efficiency.

[0026] As a further embodiment, the moving mechanism 2 includes a movable slide block 23 slidably mounted on the rinsing platform 1. A pair of mounting seats 21 are also mounted on the lower end of the rinsing platform 1. A movable lead screw 24 is rotatably mounted between the pair of mounting seats 21. A movable slider 22 at the lower end of the movable slide block 23 is threaded onto the movable lead screw 24. A movable motor 26 is also mounted on the end of each mounting seat 21. The output end of the movable motor 26 is driven by the shaft end of the movable lead screw 24. A pair of corrugated telescopic sleeves 25 are fitted around the outside of the movable lead screw 24. The pair of corrugated telescopic sleeves 25 are distributed on both sides of the movable slider 22, and both ends of the corrugated telescopic sleeves 25 are fixedly connected to the corresponding side of the movable slider 22 and the mounting seat 21, respectively. By providing the corrugated telescopic sleeves 25, the movable lead screw 24 can be protected.

[0027] The working principle of the moving mechanism 2 is as follows: When moving, the moving motor 26 is started, which drives the moving screw 24 to rotate, thereby causing the moving slider 22, which is threaded on the moving screw 24, to move the moving slide block 23, thus realizing the movement of the filter cartridge and facilitating the rinsing of the filter cartridge.

[0028] As a further embodiment, the rotating mechanism 3 includes a rotating platform 31 mounted on a movable slide 23, a turntable 32 rotatably mounted on the rotating platform 31, and a rotating motor 33 mounted at the lower end of the rotating platform 31. The output end of the rotating motor 33 is drivenly connected to the shaft end of the turntable 32.

[0029] The working principle of the rotating mechanism 3 is as follows: when rotating, the rotating motor 33 is started, and the rotating motor 33 drives the turntable 32 to rotate, which realizes the rotation of the filter cartridge, thus facilitating the rinsing of different positions of the filter cartridge.

[0030] As a further embodiment, the fixing mechanism 4 includes a fixing seat 41 mounted on the turntable 32. The fixing seat 41 has fixing grooves 44 on all four sides. A fixing slider 42 is slidably installed in each fixing groove 44. A fixing liner 43 is installed at the end of the fixing slider 42. A fixing telescopic rod 45 is also installed in the fixing groove 44. The other end of the fixing telescopic rod 45 is fixed to the fixing slider 42. A fixing spring 46 is also fitted on the fixing telescopic rod 45. The two ends of the fixing spring 46 abut against the fixing slider 42 and the fixing groove 44, respectively. The outer side of the fixing liner 43 is arc-shaped.

[0031] The working principle of the fixing mechanism 4 is as follows: When fixing, push the fixing liner 43 to move, so that the fixing slider 42 is put into the fixing groove 44. At this time, the fixing spring 46 is compressed. Then, put the filter cylinder on the outside of the fixing liner 43, and then loosen the fixing liner 43. At this time, the fixing spring 46 returns to its original position and pushes the fixing liner 43 to move, so that the filter cylinder can be fixed. The operation is simple and convenient for disassembly and assembly.

[0032] As a further embodiment, the lifting mechanism 5 includes a lifting electric cylinder 51 mounted on the rinsing frame 11. The telescopic end of the lifting electric cylinder 51 extends through the rinsing frame 11 and is fixed with a lifting seat 53. A lifting guide rod 52 is also slidably inserted on the rinsing frame 11, and the lower end of the lifting guide rod 52 is fixed to the upper end of the lifting seat 53.

[0033] The working principle of the lifting mechanism 5 is as follows: by extending and retracting the lifting electric cylinder 51, the lifting seat 53 can be raised and lowered, so that the rinsing mechanism 6 can be placed over the outside of the filter cylinder, making it convenient to rinse the filter cylinder.

[0034] As a further embodiment, the rinsing mechanism 6 includes a rinsing sleeve 64 installed at the lower end of the lifting seat 53. Multiple sets of rinsing seats 65 are distributed and installed on the inner wall of the rinsing sleeve 64. Each rinsing seat 65 is equipped with a rinsing nozzle, and the rinsing seats 65 are connected to each other via a water supply seat 66. A water tank 61 is also installed on the rinsing frame 11, and the water tank 61 and the water supply seat 66 are connected via a rinsing pipe 63. A rinsing pump 62 is also installed on the rinsing pipe 63. In this embodiment, the rinsing pipe 63 is a flexible hose.

[0035] The working principle of the rinsing mechanism 6 is as follows: During rinsing, the rinsing sleeve 64 is first placed over the outside of the rotating table 31. Then, the rinsing pump 62 is started, and the cleaning liquid in the water tank 61 is transported to the water supply seat 66 through the rinsing pump 62. Then, the cleaning liquid is sprayed out through the rinsing nozzle on the rinsing seat 65 to rinse the filter cartridge.
