Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, and in particular to a bidirectional stirring mechanism for sewage treatment. Background Technology

[0002] The bidirectional mixing mechanism of a wastewater tank is a highly efficient wastewater treatment device designed to improve the efficiency and quality of wastewater treatment through bidirectional mixing. It is a specialized component designed for wastewater treatment processes; its core function is to generate complex fluid movements within the wastewater tank through a bidirectional rotating agitator, promoting the uniform mixing and reaction of suspended solids, dissolved substances, and microorganisms in the wastewater.

[0003] Currently, the main shaft and mixing plate of traditional mixing mechanisms on the market are often integrated. When the mixing plate is worn or damaged, the entire main shaft needs to be replaced, which increases the complexity and economic cost of maintenance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bidirectional stirring mechanism for sewage tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bidirectional stirring mechanism for a sewage tank includes a sewage tank. A first support plate is fixedly installed on the top of the sewage tank. A motor is fixedly installed on the top of the first support plate. The output shaft of the motor passes vertically downward through the first support plate and is connected to the main shaft for transmission. Multiple fixed seats are fixedly installed on the main shaft. The fixed seats are arranged in upper and lower layers. Each layer is provided with two opposing fixed seats. Each fixed seat has two assembly cavities. Adaptive stirring plates are provided on both sides of the main shaft corresponding to the assembly cavities.

[0007] In addition, a preferred structure is that a second support plate is fixedly installed in each of the lower assembly cavities, and a support cavity is adapted to be opened at the bottom of the stirring plate corresponding to the second support plate.

[0008] In addition, a preferred structure is that the sides of the fixing base are provided with multiple sub-limiting cavities, and the fixing base is provided with limiting posts that are adapted to fit the sub-limiting cavities.

[0009] In addition, a preferred structure is that one end of each limiting post is provided with a thread, and the corresponding thread on each sub-limiting cavity is adapted to have a threaded cavity.

[0010] Furthermore, in a preferred configuration, the stirring plate is provided with a female limiting cavity, and each female limiting cavity is adapted to a limiting post.

[0011] Furthermore, in a preferred configuration, when the stirring plate is inserted into the assembly cavity, the female limiting cavity and the female limiting cavity are adapted and aligned.

[0012] The beneficial effects of this utility model are as follows: by interlocking the limiting post with the sub-limiting cavity and the mother limiting cavity, the stirring plate can be fixedly installed in the fixed seat. In this way, when the stirring plate needs to be replaced due to wear or damage, the user only needs to replace the stirring plate, without having to replace the entire spindle, which reduces the complexity and economic cost of maintenance.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-7A bidirectional stirring mechanism for a sewage tank includes a sewage tank 1. A first support plate 11 is fixedly mounted on the top of the sewage tank 1. A motor 2 is fixedly mounted on the top of the first support plate 11. The output shaft of the motor 2 passes vertically downward through the first support plate 11 and is connected to a main shaft 3 for transmission. Multiple fixing seats 31 are fixedly mounted on the main shaft 3. The fixing seats 31 are arranged in upper and lower layers, with two opposing fixing seats in each layer. Each fixing seat 31 has two assembly cavities 32, and matching stirring plates 4 are arranged on both sides of the main shaft 3 corresponding to the assembly cavities 32.

[0023] The sewage tank is built on the bottom surface, and the motor 2 on the first support plate 11 is a bidirectional motor, whose output shaft can rotate in both directions, thereby driving the main shaft 3 to rotate in both directions. This is existing technology, so it will not be described in detail.

[0024] Each of the lower assembly cavities 32 is fixedly equipped with a second support plate 33, and the bottom of the stirring plate 4 is fitted with a support cavity 42 corresponding to the second support plate 33. Through the fitting arrangement between the second support plate 33 and the support cavity 42, the bottom of the stirring plate 4 can be supported.

[0025] The fixing base 31 has multiple inwardly extending sub-limiting cavities 35 on its side, and each sub-limiting cavity 35 has a corresponding limiting post 5 inserted into it. One end of each limiting post 5 is provided with a thread 51, and each sub-limiting cavity 35 has a corresponding threaded cavity 34. The limiting post 5 is fixed by the fitting between the thread 51 and the threaded cavity 34.

[0026] The stirring plate 4 has a female limiting cavity 41, which is adapted to the limiting post 5. When the stirring plate 4 is inserted into the assembly cavity 32, the female limiting cavity 41 is adapted and aligned with the female limiting cavity 35. A knob is fixedly provided at one end of the limiting post 5, and the user can rotate the knob with a wrench to control the synchronous rotation of the fixed post 5 and the thread 51.

[0027] In this embodiment, the motor 2 drives the main shaft 3 to rotate in both directions, thereby causing the fixed base 31 and the stirring plate 4 to rotate synchronously. This allows the wastewater to be stirred by the stirring plate 4. This is existing technology and will not be described in detail.

[0028] Furthermore, when the stirring plate 4 needs to be replaced due to wear or damage, the user only needs to rotate the limiting post 5 inside the fixing base 31 by turning the knob. This will cause the thread 51 on the fixing post 5 to rotate within the threaded cavity 34, thereby releasing the jamming between the thread 51 and the threaded cavity 34, allowing the fixing post 5 to be pulled out. Then, the user only needs to move the stirring plate 4 upwards to remove it.

[0029] Furthermore, when installing a new mixing plate 4, the user simply inserts the mixing plate 4 downwards from the top of the assembly cavity 32 within the upper fixing base 31. At this time, the mixing plate 4 passes through the upper assembly cavity 32 and enters the lower assembly cavity 32. The second support plate 33 within the lower assembly cavity 32 is fitted and engaged within the support cavity 42 at the bottom of the mixing plate 4, thus supporting the bottom of the mixing plate 4. Simultaneously, the female limiting cavity 41 within the mixing plate 4 is aligned and engaged with the female limiting cavity 35 on the fixing base 31. The user then simply inserts the limiting post 5 into the fixing base 31, allowing the limiting post 5 to simultaneously engage within both the female and female limiting cavities, thereby securing the mixing plate 4. Finally, the user simply rotates the limiting post 5 until the thread 51 on the limiting post 5 engages with the threaded cavity 34.

[0030] In this utility model, the stirring plate 4 can be fixedly installed in the fixed seat 31 by the mutual locking between the limiting post 5, the sub-limiting cavity 35, and the female limiting cavity 41. In this way, when the stirring plate 4 needs to be replaced due to wear or damage, the user only needs to replace the stirring plate 4, without having to replace the entire spindle, which reduces the complexity and economic cost of maintenance.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
