[0032] Example 1

[0033] This embodiment is a filtration device for wastewater treatment based on PP material, which, as a connection structure of a reaction tank, includes a water inlet pipe 1 and a fixed pipe 2 connected to the reaction tank, as the main structure of this embodiment. Figure 1-Figure 2As shown, this embodiment includes a sealing device and a filter box 13 installed in the sealing device. The sealing device is installed between the water inlet pipe 1 and the fixed pipe 2. Specifically, the sealing device includes a lower shell 3 and an upper shell 6. The lower shell 3 is fixedly installed between the water inlet pipe 1 and the fixed pipe 2. As a specific implementation scheme, the end of the water inlet pipe 1 facing the sealing device has a flange 11, and the end of the fixed pipe 2 facing the sealing device has a flange 11. The lower shell 3 is fixedly connected to the flange 11. The fixed connection method is a bolt connection, so that the lower shell 3 is no longer disassembled after installation. The lower shell 3 has a lower wing plate 4, which is horizontally arranged. The lower wing plate 4 has a plurality of threaded columns 5. For example, the threaded columns 5 are arranged at the center and both sides of the lower wing plate 4. The upper shell 6 is connected to the lower shell 3. The structure is basically similar, the upper shell body 6 is provided with an upper wing plate 7, the lower wing plate 4 and the upper wing plate 7 are both horizontally arranged plate-like structures, and the upper wing plate 7 is provided with a through hole. When the upper shell body 6 is matched with the lower shell body 3, the upper wing plate 7 abuts against the lower wing plate 4, and the threaded column 5 passes through the through hole and is connected with the locking nut 8 to fix the upper shell body 6 and the lower shell body 3 together. In addition, a horizontal sealing gasket is installed between the upper wing plate 7 and the lower wing plate 4, and a lateral sealing gasket 10 is installed at the connection between the fixed pipe 2, the water inlet pipe 1 and the sealing device, so that the side end surface of the upper shell body 6 is in close contact with the lateral sealing gasket 10, thereby ensuring the sealing effect of the sealing device, and the locking nut 8 can be a butterfly nut, so that the locking nut 8 can be unscrewed or tightened by hand, which is convenient for disassembly between the upper shell body 6 and the lower shell body 3.

[0034] In this embodiment, a filter box 13 is installed in the sealing device. As a specific implementation scheme, the inner diameter of the lower shell 3 is larger than the inner diameters of the fixed pipe 2 and the water inlet pipe 1, so that the lower shell 3 forms a flange 9 with the fixed pipe 2 and the water inlet pipe 1, and the side end of the filter box 13 contacts the flange 9, and the outer periphery of the filter box 13 contacts the upper shell 6 and the lower shell 3, so that the outer periphery of the filter box 13 is clamped by the upper shell 6 and the lower shell 3, and the side end surface of the filter box 13 contacts the flange 9, so that the filter box 13 is fixed inside the sealing device. In this embodiment, the filter box 13 is convenient to be taken out of the sealing device. A pull ring 14 is installed on the upper end of the filter box 13, and the pull ring 14 is fixedly installed on the filter box 13 with a threaded structure. A through groove 12 is opened on the upper shell body 6. After the upper shell body 6 is connected to the lower shell body 3, the pull ring 14 passes through the through groove 12 to avoid interference between the pull ring 14 and the upper shell body 6. From the material of the filter box 13, the material of the filter box 13 of this embodiment is PP material to replace the currently used metal material. The PP material can be made thicker, so that the filter hole on the filter box 13 is deeper and more durable, and is not affected by acidic wastewater. The PP material is also easier to clean.

[0035] As a specific structure, such as Figure 3 As shown, as a common filter box 13 structure, the filter box 13 of this embodiment includes a shell, as an improved filter box 13 structure, such as Figure 4-Figure 5 As shown, the interior of the outer shell has an inner cylinder 15, and the inner cylinder 15 is connected to the outer shell through a partition 16. The outer shell, the inner cylinder 15, and the partition 16 all have filter holes or filter nets. When the wastewater passes through the filter box 13, the solids or flocs in the wastewater are adsorbed by the filter holes or the filter nets, thereby reducing the amount of solids or flocs in the wastewater. The filter box 13 has the inner cylinder 15 and the partition 16, so that the filter box 13 is divided into multiple areas, increasing the contact area between the filter box 13 and the wastewater, so that the filtering effect of the wastewater is better. In addition, as the structure of the inner cylinder 15, the inner cylinder 15 of this embodiment can be a hollow cylinder or a hollow prism structure, such as a regular hexagonal prism.

[0036] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0037] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
