Description

Technical Field

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

[0002] In tobacco wastewater treatment, MBBR (Moving Bed Biofilm Reactor) and A2O (Anaerobic-Anoxic-Aerobic) technologies each have their own advantages. MBBR utilizes suspended carriers to increase the biofilm attachment area, enhancing microbial degradation, resulting in high treatment efficiency and strong resistance to shock loads, making it suitable for the high concentration and recalcitrant nature of tobacco wastewater. The A2O process, on the other hand, effectively removes nitrogen and phosphorus through three stages of anaerobic, anoxic, and aerobic treatment, making it suitable for treatment scenarios requiring nitrogen and phosphorus removal. Combining the two technologies allows for complementary advantages, improving the overall treatment effect of tobacco wastewater.

[0003] For example, Chinese utility model patent (CN217230479U) discloses an A2 / O-MBBR integrated wastewater treatment device, which solves the following problem: In traditional wastewater treatment processes, the residence time of wastewater in the treatment tank is insufficient to ensure that the treated water meets the standards. Therefore, it is necessary to slow down the time when wastewater enters the treatment tank to allow the pollutants in the wastewater to react fully, thereby facilitating subsequent water treatment processes.

[0004] The device includes a treatment tank, which is a cavity with an inlet pipe at the top and an outlet pipe at the bottom. The cavity is divided into three zones: a first anoxic reaction zone, a first aerobic reaction zone, a second anoxic reaction zone, a second aerobic reaction zone, a third anoxic reaction zone, a third aerobic reaction zone, and a secondary sedimentation tank. These zones are sequentially connected. Each of the first, second, and third aerobic reaction zones contains packing material, which is polypropylene suspended packing. The inlet pipe is located at the top of each of the three anoxic reaction zones, and the outlet pipe is located at the bottom of the secondary sedimentation tank.

[0005] When using the above technology, the following technical problems were found in the existing technology: the bottom sludge of the device cannot be cleaned. If the bottom sludge is not cleaned for a long time, the sludge will continue to accumulate at the bottom of the device, occupying the space of the rectangular pool and reducing the effective treatment volume.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] As described in the background art, the sludge at the bottom of the device cannot be cleaned. If the sludge is not cleaned for a long time, it will cause the sludge to accumulate at the bottom of the device, occupying the space of the rectangular pool and reducing the effective treatment volume.

[0028] To solve this technical problem, this utility model provides a tobacco wastewater treatment device.

[0029] For details, please refer to Figures 1-8 A tobacco wastewater treatment device specifically includes: a base 1, with support blocks 2 fixed at both ends of one side of the top of the base 1, support plates 4 fixed at both ends of the other side of the top of the base 1, a water tank 5 fixed at the other side of the top of the base 1, a water inlet structure at one end of one side of the top of the base 1, a rotating filter structure at the other end of one side of the top of the base 1, a switch structure at one side of the rotating filter structure, and third connecting blocks 13 fixed at both ends of the rotating filter structure. A frame 14 is fixed to the top of the two third connecting blocks 13. A connecting groove is provided on the upper surface of the frame 14. A slider 17 is provided in the groove on each side of the frame. The lower part of the slider has the same cross-section as the groove. Normally, the cross-section of the groove is convex. One of the four sides of the frame is detachable. After the slider is installed in the groove, the other side of the frame is fixedly connected to the other sides with bolts.

[0030] The rotating filter structure includes a hydraulic cylinder 3 and a treatment tank 6. The hydraulic cylinder 3 is rotatably connected to one side of the top of the base 1, and the treatment tank 6 is rotatably connected to one side of the two support plates 4 that are close to each other. The output end of the hydraulic cylinder 3 is rotatably connected to the treatment tank 6, and the top of the two support blocks 2 is attached to one side of the bottom of the treatment tank 6, so that the rotating filter structure can filter impurities.

[0031] The switch structure includes a first connecting block 7, a first motor 8, a first bevel gear 9, a second bevel gear 10, a rotating rod 11, a cam 12, a second connecting block 15, and a spring 16. The second connecting block 15 is slidably connected to the inner side of one end of the treatment tank 6. Multiple springs 16 are fixed on both sides of the top of the second connecting block 15. The tops of the multiple springs 16 are fixed to the inner side of the treatment tank 6. The first connecting block 7 is fixed to one end of the treatment tank 6. The first motor 8 is fixed to the top of the first connecting block 7. The first bevel gear 9 is fixed to the output end of the first motor 8. The rotating rod 11 is rotatably connected to the inner side of the treatment tank 6. The cam 12 is fixed to the outer side of the rotating rod 11. The second bevel gear 10 is fixed to one side of the rotating rod 11. The second bevel gear 10 and the first bevel gear 9 are meshed and connected. The cam 12 and the second connecting block 15 are fitted together, so that the switch structure can restrict the outflow of sewage.

[0032] This application also includes a second motor 19, which is installed in the middle of the frame 14 via two bidirectional screws 18. The two bidirectional screws 18 pass through the second motor 19 in a cross shape and are respectively connected to the slider 17 that is slidably set in the slide groove of the frame 14. The second motor 19 is fixedly connected to the worm 20, which extends into the processing pool 6, and the lower end of the worm 20 is connected to a worm wheel 21.

[0033] The user energizes the hydraulic cylinder 3, causing the treatment tank 6 to rotate. Then, the user energizes the first motor 8, causing it to rotate. The output of the first motor 8 drives the first bevel gear 9 to rotate. Since the first bevel gear 9 is meshed with the second bevel gear 10 on one side, the rotation of the first bevel gear 9 drives the second bevel gear 10 to rotate, which in turn drives the rotating rod 11 and the cam 12 to rotate. Under the elastic force of multiple springs 16, the second connecting block 15 slides on one side of the treatment tank 6, allowing the sewage to flow out from one side of the treatment tank 6 and enter the water tank 5. Large impurities are screened out by the treatment tank 6.
