[0002] In the biochemical treatment system of a sewage treatment plant, fillers containing microorganisms are generally used to treat sewage. However, when sewage is injected into the sewage treatment pool or when the sewage treatment pool is drained, the fillers are easily discharged from the sewage treatment pool with the water. After the fillers flow out, the subsequent sewage cannot be thoroughly treated, which affects the sewage treatment effect. Moreover, if the fillers are not handled in time after flowing out, they will cause blockage and damage to the subsequent treatment structures. Therefore, the water inlet and outlet in the sewage treatment pool are usually covered with filters to block the fillers.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1The utility model provides a technical solution for the intercepting screen structure of the sewage pool: the intercepting screen structure of the sewage pool includes a sewage pipe 1, a filter cabin 5 is fixedly connected to the middle part of the sewage pipe 1, and the water flow of the sewage pipe 1 is divided by the filter cabin 5, and the middle part of the top of the filter cabin 5 is fixedly connected to the component shell 3. The filter cabin 5 and the component shell 3 are penetrated and connected with three switch gate components 2 in a sliding manner up and down. The cabin can be closed by the switch gate component 2, and the opening state of the cabin can be adjusted according to needs. A removal groove is provided at the top of the filter cabin 5 in a position parallel to the front of the switch gate component 2, and a filter screen component 4 is slidably connected in the removal groove. The filter screen component 4 can intercept and filter the sewage flowing through to prevent the purification material in the sewage tank from flowing out together.

[0024] See also Figure 2 The filtration cabin 5 includes a cabin body 51, the front and rear ends of the cabin body 51 are fixedly connected to the inside of the sewage pipe 1, and two partition columns 52 are evenly fixedly connected to the middle of the bottom end of the inner side of the cabin body 51. The partition columns 52 divide the interior of the cabin body 51 into three cabins. The rear end of the partition column 52 is fixedly connected to a guide rib 53, which can guide the sewage into the cabin. The left and right sides of the partition column 52 are slidably connected to the opposite sides of the two adjacent switch gate components 2, and the opening of the cabin can be controlled by sliding the switch gate component 2 up and down.

[0025] See also Figure 3 The switch gate component 2 includes a blocking gate 24, which is slidably connected to the opposite sides of the two adjacent partition columns 52 and the opposite sides of the partition columns 52 and the cabin body 51. The blocking gate 24 is slidably connected to the inside of the component shell 3. The front side of the blocking gate 24 is fixedly connected to the lifting rack 23, and the front side of the lifting rack 23 is meshed with the lifting gear 21. The right end of the lifting gear 21 is rotatably connected to the driving column 22, and the bottom end of the driving column 22 is fixedly connected to the top of the cabin body 51. The driving column 22 and the lifting gear 21 are both located inside the component shell 3.

[0026] The driving column 22 can drive the lifting gear 21 to rotate, so that the lifting gear 21 drives the blocking gate 24 to move up and down. The upward movement opens the cabin to allow sewage to pass through. Different numbers of blocking gates 24 can be opened as needed to control the sewage discharge efficiency, and the sewage discharge rate can be adjusted through the blocking gates 24 to meet different needs.

[0027] See also Figure 4The filter screen component 4 includes a screen outer frame 42, and an intercepting screen 43 is fixedly connected to the inner side of the screen outer frame 42. The screen outer frame 42 provides support for the intercepting screen 43 to move. The intercepting screen 43 intercepts and filters the passing sewage flow and can be replaced according to different needs. A pulling component 41 is fixedly connected to the top of the screen outer frame 42. The pulling component 41 can help the screen outer frame 42 to be taken out faster. A snap groove is provided on the upper side of the front end of the screen outer frame 42.

[0028] See also Figure 4 The left and right ends of the partition column 52 are provided with sliding grooves on the front side, and the upper side of the front end of the sliding groove is fixedly connected with a fixed rib, which can enter the buckle groove. The distance between the rear side of the sliding groove and the rear end of the fixed rib can be passed through the screen outer frame 42. When the screen outer frame 42 is inserted into the sliding groove, it reaches the bottom and contacts the bottom end of the cabin body 51. The fixed rib is connected and fixed to the buckle groove to ensure the position of the screen outer frame 42 when the water flow impacts from the rear side of the screen outer frame 42. At the same time, the fixed rib can prevent the screen outer frame 42 from moving up. When it needs to be taken out, pull the lifting assembly 41 forward to disengage the buckle groove from the fixed groove and lift it out.

[0029] See also Figure 5 The lifting assembly 41 includes a lifting handle 411, and a lifting rope 412 is fixedly connected to the left and right sides of the lifting handle 411.

The two support blocks 414 are rotatably connected to the opposite sides with a lifting roller 413, and the lifting rope 412 can slide on the outer surface of the lifting roller 413.

[0030] When the lifting handle 411 drives the screen outer frame 42, 512 can cause a protrusion to appear on the outer surface of the lifting roller 413 between the lifting rope 412 and the screen outer frame 42, causing the bottom end of the screen outer frame 42 to move forward, making it easier for the screen outer frame 42 to separate from the fixed edge, making it more convenient to remove the entire filter screen component 4.

[0031] Working principle:

[0032] First, the three inner compartments of the compartment body 51 are closed by controlling the lifting of the blocking gate 24 through the lifting gear 21, and then the filter screen component 4 is placed through the sliding groove. The blocking gate 24 of the corresponding compartment is opened as needed to allow the water to be discharged and filtered through the filter screen component 4. When the filter screen component 4 needs to be cleaned, the corresponding compartment is closed and other compartments are opened to continue working. By pulling the lifting handle 411, the screen outer frame 42 moves out of the fixed edge and then pulls it out of the sliding groove for cleaning.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
