[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] An industrial parallel-inlet three-stage disc filter includes a filter housing body 1 and a filter element 6. The filter housing body 1 has a filter chamber 5 inside. The top of the filter element 6 is provided with a handle 7. The bottom of the filter element 6 is provided with a fixing post 9. The bottom surface of the fixing post 9 is provided with a telescopic post 14. The bottom side wall of the telescopic post 14 is symmetrically provided with spring plungers 16. The bottom surface of the filter chamber 5 has a groove 8. The inner wall of the groove 8 is rotatably connected to the end of the spring plunger 16. The inner side wall of the groove 8 has symmetrical grooves 17. The inner wall of the grooves 17 is engaged with the spring plunger 16.

[0028] The inner wall of the groove 17 is also slidably equipped with an ejector component.

[0029] The filter element 6 is secured by a telescopic column 14 located inside the bottom surface of the fixing column 9. Symmetrical spring plungers 16 at the bottom of the telescopic column 14 engage with symmetrically formed grooves 17 inside the slot 8. This allows workers to press the telescopic column 14 inside the fixing column 9 at the bottom of the filter element 6 into the slot 8, and then rotate the filter element 6 to eject the spring plungers 16 from the grooves 17, thus securing the filter element 6. Conversely, the spring plungers 16 can be pushed out of the grooves 17 by the ejector assembly, allowing for disassembly and cleaning of the filter element 6.

[0030] The ejection assembly includes a stop post 23. The outer arc surface of the stop post 23 is slidably connected to the inner wall of the groove 17. The end of the stop post 23 abuts against the end of the spring plunger 16. By setting the bottom end of the stop post 23 to abut against the end of the spring plunger 16 and the outer arc surface of the stop post 23 to slidably connect to the inner wall of the groove 17, the spring plunger 16 can pop out from inside the groove 17 to squeeze the stop post 23, which facilitates the spring plunger 16 to be snapped into place and the filter element 6 to be fixed.

[0031] A circular hole 19 is symmetrically provided on the outer side of the groove 17 inside the filter housing body 1. A mounting groove 18 is symmetrically provided above and below the circular hole 19. The inner walls of the mounting groove 18 and the circular hole 19 are slidably connected to the limiting piece 22. The side wall of the limiting piece 22 is fixedly installed to the side wall of one end of the top rod 20. The other side wall of the limiting piece 22 is fixedly installed to the abutment 23. The inner wall of the circular hole 19 is slidably connected to the top rod 20.

[0032] A circular hole 19 is provided on both sides of the groove 17 inside the filter housing body 1. A mounting groove 18 is symmetrically provided above and below the circular hole 19. The inner walls of the mounting groove 18 and the circular hole 19 are slidably connected to the limiting piece 22. The side wall of the limiting piece 22 is fixedly installed to one end of the top rod 20 so that the spring plunger 16 can press the abutment 23, so that the limiting piece 22 can press the first spring 21, so that the end of the top rod 20 can pop out from the circular hole 19. This makes it easy for the worker to press the top rod 20 to squeeze the spring plunger 16 inside the groove 17 out of the groove 17 and disassemble the filter element 6.

[0033] The end of the mounting groove 18 near the outside of the filter housing body 1 is located inside the round hole 19. By setting the end of the mounting groove 18 near the outside of the filter housing body 1 to be located inside the round hole 19, the first spring 21 can be used to fix the top rod 20.

[0034] The limiting plate 22 is provided with a first spring 21 on the side wall above and below the top rod 20, and the other end of the first spring 21 is fixedly installed on the inner wall of the mounting groove 18 near the round hole 19.

[0035] The top surface of the telescopic column 14 is fixedly installed with the bottom end of the second spring 12. The side wall of the second spring 12 is symmetrically provided with insert blocks 13. The top end of the second spring 12 is fixedly installed with the inner top surface of the movable groove 10 opened inside the fixed column 9. The inner wall of the movable groove 10 is symmetrically provided with limit grooves 11. The inner wall of the limit groove 11 is slidably connected with the insert block 13.

[0036] By fixing the top surface of the telescopic column 14 to the second spring 12, and fixing the top of the second spring 12 to the inner top surface of the movable groove 10 opened inside the fixed column 9, and symmetrically opening the limit groove 11 on the inner wall of the movable groove 10, and slidingly connecting the inner wall of the limit groove 11 to the insert block 13 on both sides of the second spring 12, the filter element 6 can be installed by pressing the telescopic column 14, which extends and retracts inside the fixed column 9 at the bottom of the filter element 6, to the inner bottom surface of the slot 8, and then rotating the filter element 6 to make the spring plunger 16 pop out from the groove 17, thereby snapping and fixing the filter element 6.

[0037] The bottom end of the insert block 13 is not connected to the bottom end of the fixing post 9. The bottom end of the fixing post 9 is symmetrically provided with a slot 24 directly below the limiting groove 11. The slot 24 is inserted into the card block 15. The card block 15 is symmetrically arranged on the outer arc surface of the telescopic post 14 and is located directly below the insert block 13.

[0038] By providing a slot 24 on the bottom surface of the fixed column 9 and symmetrically providing a locking block 15 on the outer arc surface of the telescopic column 14, the locking block 15 engages with the slot 24 to fix the telescopic column 14, thus preventing the telescopic column 14 from rotating inside the fixed column 9 when the worker rotates the filter element 6, thus preventing the spring plunger 16 on the side wall of the telescopic column 14 from rotating.

[0039] Two sets of locking blocks 15 and two sets of spring plungers 16 are arranged in a cross shape on the side wall of the telescopic column 14. By setting two sets of locking blocks 15 and two sets of spring plungers 16 in a cross shape on the side wall of the telescopic column 14, the locking blocks 15 can engage with the inner wall of the slot 24 when the spring plunger 16 rotates inside the slot 8, so as to drive the spring plunger 16 to rotate.

[0040] The top of the filter housing body 1 is provided with a top cover 2 which is rotatably mounted on a hinge, and the filter housing body 1 has an inlet pipe 3 and an outlet pipe 4 on both sides respectively.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
