Description

Technical Field

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

[0002] This method utilizes the metabolic activity of microorganisms to remove organic pollutants from wastewater. It is also known as wastewater biochemical treatment or simply wastewater biochemical treatment. There are two types: aerobic biological treatment and anaerobic biological treatment. Aerobic biological treatment uses aerobic microorganisms to decompose complex organic matter in wastewater under aerobic conditions. Typical organic matter in domestic sewage includes carbohydrates, synthetic detergents, fats, proteins, and their decomposition products such as urea, glycine, and fatty acids.

[0003] For example, patent document CN 207581588 U discloses a wastewater biochemical treatment device, including a tank body. The tank body has an internal partition that can slide left and right. A wastewater inlet pipe is located near the top on the left side of the tank body, and an outlet pipe for outputting purified water is located near the middle on the right side of the tank body. A sludge scraper is located at the bottom left side of the partition, with its left end fitting against the inner bottom of the tank body. The tank body is divided into a sedimentation tank and an anaerobic tank by the partition, with the sedimentation tank located on the left side. A sludge guide plate is located near the bottom left side of the tank body, and a sludge discharge pipe is located on the left side of the tank body. This device can achieve automatic sludge cleaning, shortening cleaning time.

[0004] However, in actual use, staff can only perform simple internal wall scraping and cleaning. But because the large amount of substances produced by wastewater biochemical treatment are highly adhesive, they stick to the internal wall, resulting in poor actual cleaning effect. At the same time, the equipment cannot perform more stable internal operations for wastewater biochemical treatment and cannot meet daily usage needs. Therefore, it is urgent to design a wastewater biochemical treatment device to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a wastewater biochemical treatment device to solve the problem mentioned in the background art. In actual use, the existing structure can only be cleaned by simple scraping of the inner wall. However, due to the large amount of substances produced by wastewater biochemical treatment, which have great stickiness, they stick to the inner wall, resulting in poor actual cleaning effect of the equipment. At the same time, the equipment cannot carry out more stable operation inside the wastewater biochemical treatment process, and cannot meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater biochemical treatment device, comprising an outer treatment tank, an upper mounting frame movably connected to the top of the outer treatment tank, a lower mounting frame movably connected to the bottom of the outer treatment tank, and an inner treatment liner provided inside the outer treatment tank;

[0007] The side lifting frame and the lifting ring shaft seat are fixedly connected to the side of the outer tank. The lifting ring shaft seat is movably connected inside the upper mounting frame. The top of the side lifting frame is equipped with a first drive motor.

[0008] Preferably, a lifting screw is fixedly connected to the bottom end of the first drive motor, and a lifting sleeve is fitted on the outer surface of the lifting screw.

[0009] Preferably, a second drive motor is provided on the side of the lifting ring shaft seat, and a drive gear is provided at the bottom end of the second drive motor.

[0010] Preferably, a drive gear ring is provided at the bottom end of the lifting ring shaft seat, a drive ring cutter is fixedly connected to the bottom end of the drive gear ring, and a damping rubber ring is provided between the drive gear ring and the lifting ring shaft seat.

[0011] Preferably, the inner wall of the outer processing tank is provided with a processing groove, and the inner wall of the inner processing liner is provided with a protective coating.

[0012] Preferably, the inner wall of the outer processing tank is fixedly connected with limiting grooves on all four sides, and the inner processing tank has limiting strips on all four sides of its side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This wastewater biochemical treatment device, through its outer treatment tank, side lifting frame, lifting ring shaft seat, first drive motor, lifting screw, lifting sleeve, second drive motor, drive gear, drive gear ring, drive ring cutter, and damping rubber ring, enables more efficient internal wall cleaning and maintenance operations for wastewater biochemical treatment. In actual use, workers first perform biochemical treatment on the wastewater inside the outer treatment tank. After a certain period of treatment, all the wastewater material inside the outer treatment tank can be discharged. Then, the first drive motor at the top of the side lifting frame is started, which drives the lifting screw to... The internal rotation adjustment of the side lifting frame causes the lifting sleeve to rotate around the side lifting frame, driving the entire lifting ring shaft seat. During the lifting and adjustment operation inside the outer tank, the second drive motor fixed to the inner wall of the lifting ring shaft seat is activated, which drives the drive gear at the bottom to rotate. The drive gear then drives the drive gear ring and drive ring cutter at the bottom of the lifting ring shaft seat to rotate. The drive ring cutter performs a high-speed circular contact and rotation cleaning operation on the inner wall of the outer tank, effectively removing the sticky substances inside the outer tank and ensuring the stability of subsequent biological treatment of sewage in the outer tank, demonstrating the practicality of the equipment design.

[0015] This wastewater biochemical treatment device, through its outer treatment tank, upper mounting frame, lower mounting frame, inner treatment tank, treatment trough, protective coating, limiting grooves, and limiting strips, further enhances the overall performance of the equipment. During daily use, operators can quickly insert and remove the upper mounting frames at both ends of the outer treatment tank to clean and maintain the side lifting frames. Simultaneously, the inner treatment tank inside the treatment trough can be easily removed for quick replacement. Furthermore, the inner treatment tank can be positioned and connected with the limiting grooves on the four sides of the outer treatment tank via the limiting strips on all four sides, ensuring continuous wastewater biochemical treatment and demonstrating the comprehensiveness of the equipment design.
