[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, a wastewater treatment device for environmental engineering includes a wastewater treatment shell 1, which comprises an equipment frame 11 and a main shell 12. The main shell 12 is installed in the middle of the equipment frame 11 and is fixedly connected to the equipment frame 11. An inner shell 2 is placed inside the main shell 12, and a tower-type filter assembly 3 is installed in the inner shell 2. The tower-type filter assembly 3 is detachably connected to the inner shell 2. A tilting bracket 4 for limiting the tower-type filter assembly 3 is also installed on the upper surface of the inner shell 2. One end of the tilting bracket 4 is rotatably connected to the inner shell 2, and the other end is fixedly connected to the inner shell 2. The main body of the device includes the wastewater treatment shell 1, the equipment frame 11, the main shell 12, the inner shell 2, the tower-type filter assembly 3, and the tilting bracket 4. During use, the tower-type filter assembly 3 is detachably connected to the inner shell 2, which facilitates the replacement and maintenance of the filter assembly, improving the service life and maintenance efficiency of the wastewater treatment device. The tilting baffle 4 can effectively limit the tower filter screen group 3, preventing it from shaking or shifting during sewage treatment, thus ensuring the stability of the filtration effect.

[0028] Reference Figure 2 As shown, the equipment frame 11 includes a top frame 111, longitudinal corner bars 112, and a water platform 113. The longitudinal corner bars 112 are evenly installed at the four corners of the lower end face of the top frame 111. The water platform 113 is located directly below the top frame 111, and its corners are fixedly connected to the longitudinal corner bars 112. By designing the equipment frame 11 as a structure in which the top frame 111, longitudinal corner bars 112, and water platform 113 cooperate, a stable support frame is provided for the entire wastewater treatment device during use, ensuring that the device will not shake or tilt during operation. The longitudinal corner bars 112 are evenly distributed at the four corners of the top frame 111, which can evenly bear the weight of the device, improving the load-bearing capacity of the equipment frame 11. The water platform 113 provides a platform for the installation and support of components such as the drain bend 123, making the structure of the device more reasonable.

[0029] Reference Figure 2As shown, the main housing 12 includes a square shell portion 121, a conical shell portion 122, and a drain bend 123. The square shell portion 121 is fixedly installed in the top frame 111. The conical shell portion 122 is integrally formed on the lower end face of the square shell portion 121. The drain bend 123 is fixedly installed on the lower end face of the conical shell portion 122 and is fixedly connected to the water platform 113. By designing the main housing 12 into a structure where the square shell portion 121, the conical shell portion 122, and the drain bend 123 cooperate, the square shell portion 121 can be fixedly installed in the top frame 111 during use, ensuring the connection stability between the main housing 12 and the equipment frame 11. The conical shell portion 122 is integrally formed on the lower end face of the square shell portion 121, which facilitates the flow of sewage to the drain bend 123 under gravity, improving drainage efficiency. The drain bend 123 can change the discharge direction of sewage, facilitating connection with subsequent sewage treatment pipelines and making the entire sewage treatment system smoother.

[0030] Reference Figure 3 and Figure 4 As shown, the inner shell 2 of the equipment includes a frame shell 21 and a bottom support ring 22 supporting the tower filter assembly 3. The bottom support ring 22 is installed on the lower end face of the frame shell 21 and is integrally formed with the frame shell 21. By setting the inner shell 2 of the equipment into a structure in which the frame shell 21 and the bottom support ring 22 cooperate, and by making the bottom support ring 22 integrally formed with the frame shell 21, stable support is provided for the tower filter assembly 3. This structural design allows the tower filter assembly 3 to be firmly installed in the inner shell 2 of the equipment, preventing it from shifting during the filtration process and ensuring the reliability of the filtration effect.

[0031] Reference Figure 6 As shown, the tower filter assembly 3 includes a central tower block 31, inclined filter plates 32, and a bottom ring seat 33.

The bottom ring seat 33 is fixedly installed on the upper surface of the inclined filter plates 32. By designing the tower filter assembly 3 with a structure in which the central tower block 31, inclined filter plates 32, and bottom ring seat 33 cooperate, the inclined filter plates 32 are evenly inclined and arranged on the outer surface of the central tower block 31 during use, which effectively increases the filtration area of ​​the filter and improves the filtration efficiency. The bottom ring seat 33 further fixes the inclined filter plates 32, preventing them from deforming or loosening during the filtration process and ensuring the filtration effect of the filter.

[0032] Reference Figure 4 and Figure 5As shown, the tilting baffle 4 includes a central block 41, a first bent rod 42, and a second bent rod 43. The first bent rod 42 and the second bent rod 43 are fixedly installed on both sides of the central block 41, and the two ends of the first bent rod 42 are rotatably installed on the upper end face of the frame shell 21. The two ends of the second bent rod 43 are fixedly installed with outer ear plates 431 connected to the frame shell 21. Several clamping bolts 411 are vertically installed on the central block 41, and the clamping bolts 411 are threadedly connected to the central block 41. By setting the tilting baffle 4 into a structure in which the central block 41, the first bent rod 42, and the second bent rod 43 cooperate, it is ensured that the two ends of the first bent rod 42 are rotatably installed on the upper end face of the frame shell 21 during use, so that the tilting baffle 4 can be flexibly tilted, facilitating the installation and disassembly of the tower filter assembly 3. The outer ear plates 431 at both ends of the second bent rod 43 are fixedly connected to the frame shell 21, ensuring the stability of the tilting baffle 4 when limiting the tower filter assembly 3. The clamping bolts 411 on the center block 41 can further tighten the tower filter assembly 3 to prevent it from shaking during operation and improve the stability of the filtration effect.

[0033] In this embodiment, during actual processing, the wastewater to be treated is introduced into the inner shell 2 of the equipment. The wastewater is filtered by the tower filter group 3, and impurities are intercepted on the inclined filter plate 32. The filtered water is discharged through the drain bend 123, while the impurities can flow along the inclined filter plate 32 into the inner shell 2 below for collection. When cleaning is required, the inner shell 2 and the tower filter group 3 can be extracted. Then, the clamping bolt 411 is loosened, and the rotating baffle 4 is rotated to remove the tower filter group 3 from the inner shell 2. The impurities in the inner shell 2 can also be quickly cleaned.

[0034] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
