Technical Field

[0001] The utility model belongs to the technical field of concrete sewage tanks, in particular to a leakage-proof prefabricated assembled concrete sewage tank. Background Art

[0002] A prefabricated concrete sewage tank is a sewage storage and treatment facility in which concrete components are prefabricated in a factory and then transported to the construction site for assembly and installation. In the factory, concrete components of various shapes and sizes, such as pool wall panels, pool bottom panels, and top covers, are manufactured using molds and high-quality concrete materials according to design requirements and standards. The quality of these components can be better controlled during the production process to ensure that the strength, impermeability and other properties of the concrete meet the design requirements. Prefabricated concrete sewage tanks have many advantages. First, factory production can improve the accuracy and quality consistency of components and reduce quality fluctuations during on-site construction. Second, the prefabricated construction method greatly shortens the on-site construction time and improves the construction efficiency of the project. Third, since most of the work is completed in the factory, wet operations on the construction site are reduced, reducing the impact on the environment.

[0003] The Chinese patent with the announcement number "CN208615050U" discloses a motor stirring device for a concrete sewage tank, which solves the technical problem that the position of the stirrer is fixed at one position in the sewage tank, resulting in poor stirring effect. The key points of its technical solution are as follows: it includes a sewage tank, a motor, the lower end of the motor is connected to a support frame, the bottom end of the support frame is fixedly connected to a base, the pool mouth of the sewage tank is provided with a protective net covering the pool mouth, the lower end of the protective net is fixedly connected to a plurality of support rods, the upper end of the protective net is provided with a support plate extending from the pool walls on both sides of the sewage tank, the support plate and the protective net are jointly provided with a slide groove for the base to slide; the support plate is connected to a driving member that enables the base to slide in the slide groove; the technical effect is that the motor stirring device for the concrete sewage tank can move in the sewage tank while stirring the sewage tank, thereby improving the stirring effect;

[0004] However, during the application of the above-mentioned device, the stirring mechanism inside the pool body has obvious limitations. It can only perform lateral linear displacement adjustment. During the stirring process, it can only stir the positions on the linear displacement path. However, during the specific application, the other two sides of the pool body lack corresponding stirring structures, which makes it impossible to flexibly adapt to the stirring and mixing needs inside the pool body and achieve all-round and dead-angle stirring effects. At the same time, the existing concrete prefabricated sewage pool body lacks high-strength anti-leakage function as a whole. After long-term use, it is prone to leakage. It can be seen that the existing technology as a whole still has certain defects and shortcomings, which needs to be further improved and perfected. Utility Model Content

The adjustment mechanism 4 shows many significant advantages. The solid connection between the bottom and the top of the concave seat 41 ensures the stability of the overall structure. The chute 42 opened on the top is slidably connected with the slide 43 with a convex cross-section. This unique shape design makes the slide 43 slide more stably and accurately in the chute 42, and is not prone to offset or dislocation. The stirring mechanism 5 is fixedly installed at the bottom of the slide 43, providing a solid support for the stirring work. The driving force on one side of the concave seat 41 The component 44 is exquisitely designed. The circular plates 441 at both ends provide reliable rotation support for the screw rod 442.

This unique shape design not only increases the stability of the structure, but also can generate stirring forces in different directions during stirring, further improving the comprehensiveness and uniformity of stirring. In addition, the stirring rod 54, the stirring guide plate 55 and the rotating shaft 52 are all made of stainless steel, which has excellent corrosion resistance and wear resistance. Stainless steel can maintain good performance in harsh environments with long-term contact with sewage and is not easy to rust and damage, thereby extending the service life of the entire stirring device and reducing maintenance and replacement costs.

[0031] Principle and advantages of use: The concrete base 21 provides a solid structural foundation. It has high strength and bearing capacity, and can withstand loads such as water pressure inside the sewage pool and external soil pressure, ensuring that the sewage pool will not deform or collapse during use. Secondly, the polyurethane waterproof layer 22 plays a key waterproof role. Polyurethane has excellent waterproof performance and can effectively prevent water penetration. Its good flexibility can adapt to the fine cracks and deformations that may occur in the concrete base 21, ensuring the integrity and effectiveness of the waterproof layer. For example, in areas with high groundwater levels, the polyurethane waterproof layer 22 can effectively block the infiltration of groundwater and prevent sewage in the sewage pool from leaking into the surrounding soil and causing environmental pollution. Furthermore, the waterproof mortar layer 23 further enhances the waterproof effect. The waterproof mortar has good anti-seepage performance and can fill the tiny pores and defects on the surface of the concrete base 21 to form a dense protective layer. For example, in sewage The waterproof mortar layer 23 can play a role in strengthening waterproofing in the corners and edges of the pool where leakage is likely to occur. In addition, this combination of multi-layer structures also improves the durability of the sewage pool. The strength of the concrete base 21 plus the protection of the waterproof layer and the waterproof mortar layer 23 reduce the erosion of sewage on the concrete and extend the service life of the sewage pool. Moreover, the prefabricated assembly method makes construction more convenient and efficient. The various components are prefabricated in the factory and then assembled on site, which greatly shortens the construction period and reduces construction costs. Compared with the traditional on-site casting construction method, prefabricated assembly can reduce on-site wet operations and reduce the impact on the construction environment. It can be seen that the concrete prefabricated sewage pool composed of the concrete base 21, the polyurethane waterproof layer 22 and the waterproof mortar layer 23 has significant advantages in structural strength, waterproof performance, durability, construction efficiency, etc., and can provide reliable, stable and long-term effective facility guarantees for sewage treatment.

[0032] By arranging the cooperation of the stirring mechanism 5 and the adjusting mechanism 4, the present device can be operated by starting the third motor 51 during use, and the third motor 51 drives the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 can drive the auger 53 and the stirring rod 54 to rotate. The rotation of the auger 53 can assist in transmitting sewage from bottom to top, so that the sewage can be efficiently stirred and mixed, which can improve the reaction efficiency of sewage and reagents during sewage treatment. Moreover, as the rotating shaft 52 drives the stirring rod 54 and the stirring guide plate 55 to rotate, it can assist in further stirring and mixing the tumbling sewage, so that the sewage can be mixed and stirred more efficiently. During the stirring period, by starting the second motor 443 to run, the second motor 443 can drive the screw rod 442 to drive the slide plate 43 to linearly move on the inner side of the slide groove 42. At this time, the stirring mechanism 5 can be driven to slide in a linear displacement, thereby achieving a better stirring and mixing effect on the sewage and increasing its stirring area.

[0033] By setting up the driving mechanism 3, during use of the device, on the basis of the linear displacement of the adjusting mechanism 4, the gear 35 can be driven to rotate by starting the first motor 34, and the gear 35 and the gear ring 31 are meshed and connected. At this time, the rotation of the gear 35 can drive the slide 32 to rotate in the opposite direction. By adjusting the rotation of the slide 32, the entire concave seat 41 and the slide 42 can be driven to rotate. The rotation of the concave seat 41 can change the direction of the slide 42 and the inner slide 43 thereof, thereby causing the linear displacement direction of the slide 43 to be adjusted, so that the stirring mechanism 5 can rotate along the pool body 1 during the linear period. Through the linear displacement combined with the rotation adjustment, the stirring mechanism 5 of the device can be arbitrarily adapted for stirring within the circular range with the pool body 1 as the diameter. The overall further adjustable design can maximize the trial mixing inside the pool body 1, thereby improving the overall stirring capacity of the device, avoiding the occurrence of dead corners in stirring and mixing, and improving its overall stirring quality.
