[0028] 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.

[0029] Reference Figure 1-10A wastewater treatment device for easy replacement of primary filter screen includes a wastewater treatment tank 1, a filter screen mounting frame 2 horizontally inserted into the wastewater treatment tank 1, a filter screen 4 placed on the filter screen mounting frame 2, a pressure ring 5 rotatably mounted on the filter screen mounting frame 2, the pressure ring 5 pressing the filter screen 4 tightly, two limiting grooves 52 are opened on one side of the pressure ring 5, two limiting components 9 are movably arranged in one end of the filter screen mounting frame 2, two limiting block hidden grooves 24 are opened at one end of the filter screen mounting frame 2, a cylindrical groove 25 is opened on one side of the limiting block hidden groove 24, a limiting card groove 27 and an unlocking card groove 26 are respectively opened on one side of the limiting block hidden groove 24 and the cylindrical groove 25, and two movable grooves 23 are opened at the top of one end of the filter screen mounting frame 2, the movable grooves 23 are connected to the limiting block hidden grooves 24 and the cylindrical grooves 25;

[0030] The limiting component 9 includes a limiting block 91, a connecting rod 92 rotatably mounted at one end of the limiting block 91, a locking plate 922 mounted at one end of the connecting rod 92, a pull rod 923 mounted on one side of the locking plate 922, the limiting block 91 is movably located in the limiting block hidden groove 24, one end of the limiting block 91 is pressed into the limiting groove 52, the connecting rod 92 is movably located in the cylindrical groove 25, and the locking plate 922 is locked into the limiting locking groove 27.

[0031] Meanwhile, slot 13 is provided on both sides of the inner wall of sewage treatment tank 1, slot 2 14 is provided on the other side of the inner wall of sewage treatment tank 1, and through groove 12 is provided on the other side of sewage treatment tank 1. Two threaded holes 11 are provided at both ends of through groove 12, and sealing grooves 121 are provided on the top and bottom sides of through groove 12.

[0032] Furthermore, insert strip 6 is provided on both sides of the filter mounting bracket 2, insert strip 7 is provided on the other side of the filter mounting bracket 2, and two mounting blocks 22 are provided on both sides of one end of the filter mounting bracket 2. Insert strip 6 is slidably inserted into slot 13, and insert strip 7 is inserted into slot 24. Bolt 3 passes through the mounting block 22 and is threaded into the threaded hole 11 to limit the filter mounting bracket 2.

[0033] Meanwhile, rotating holes 21 are opened on both sides of one end of the filter mounting bracket 2. Two limiting posts 8 are fixedly installed on the three ends of the filter mounting bracket 2. The limiting posts 8 are inserted into the filter holes of the filter 4, and the limiting posts 8 initially limit the position of the filter 4.

[0034] Furthermore, rotating posts 51 are provided on both sides of one end of the pressure ring 5. The rotating posts 51 are located in the rotating hole 21, and the pressure ring 5 can rotate around the rotating hole 21 as the axis.

[0035] Meanwhile, the bottom of the limiting block 91 is arc-shaped, which makes it easy for the limiting block 91 to squeeze into the limiting groove 52, thereby making the pressure ring 5 press the filter screen 4 tightly. One end of the limiting block 91 has a rotating groove 911, and a rotating column 921 is provided on one side of the connecting rod 92. The rotating column 921 rotates within the rotating groove 911. When the connecting rod 92 rotates, the limiting block 91 will not rotate.

[0036] Furthermore, sealing strips 10 are provided on both the top and bottom sides of one end of the filter mounting bracket 2. The sealing strips 10 are inserted into the sealing groove 121 to prevent sewage from flowing out.

[0037] In this embodiment, the bolt 3 is removed from the threaded hole 11 by tightening the bolt 3. Then, the filter screen mounting bracket 2 is pulled to remove the filter screen mounting bracket 2 from the sewage treatment tank 1. The pull rod 923 is pulled to move the locking plate 922 away from the limiting slot 27. Then, the locking plate 922 is pushed to move in the movable slot 23, causing the limiting block 91 to leave the limiting slot 52 of the pressure ring 5 and enter the limiting block hidden slot 24. When the position of the locking plate 922 is aligned with the unlocking slot 26, the pull rod 923 is pushed to make the locking plate 922 lock into the unlocking slot 26. The operation of the other limiting component 9 is the same as the above operation, so that the two limiting blocks 91 leave the limiting slots 52 of the two pressure rings 5 ​​respectively. At this time, the pressure ring 5 is pulled to make the pressure ring 5 rotate around the rotating column 51 as the axis. Then, the filter screen 4 can be taken out.

[0038] Replace the filter screen 4 and place it on the filter screen mounting bracket 2. Insert the limiting post 8 into the filter holes of the filter screen 4. At this time, rotate the pressure ring 5 to press the filter screen 4 tightly. Then, pull the lever 923 to drive the locking plate 922 away from the unlocking slot 26 and push the locking plate 922 to move in the movable slot 23. When the locking plate 922 is aligned with the limiting slot 27, the limiting block 91 is squeezed into the limiting slot 52 of the pressure ring 5. Push the lever 923 to drive the locking plate 922 to lock into the limiting slot 27. When both limiting blocks 91 are squeezed into the two limiting slots 52 of the pressure ring 5, the pressure ring 5 firmly presses the filter screen 4.

[0039] Next, the filter mounting bracket 2 enters the sewage treatment tank 1 through the through groove 12, the insert 6 slides into the slot 1 13, the insert 7 is inserted into the slot 2 14, and the bolt 3 is threaded through the mounting block 22 and then inserted into the threaded hole 11.

[0040] In this utility model, by removing the filter screen mounting bracket 2 from the sewage treatment tank 1, and removing the card plate 922 from the limiting card groove 27 and inserting it into the unlocking card groove 26, the limiting block 91 leaves the limiting groove 52. After rotating the pressure ring 5, the filter screen 4 can be removed for replacement, making it convenient to replace the filter screen 4.

[0041] 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.
