[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] Example 1

[0027] like Figure 1 - Figure 8As shown, this utility model provides a technical solution: a semiconductor cleaning liquid filtration device, including: a filtration mechanism 1, a fixing mechanism 2 is provided inside the filtration mechanism 1, a pressing mechanism 3 is provided on one side of the fixing mechanism 2, the pressing mechanism 3 includes an extension plate 31, four slots 32 are provided in a ring shape on the outer side of the extension plate 31, two fixing posts 33 are symmetrically arranged below the extension plate 31, a sliding block 34 is provided inside one side of each of the two fixing posts 33, a threaded rod 35 is provided at the top of each of the two fixing posts 33, a sliding groove 36 is provided at the bottom of each of the two threaded rods 35, a sliding groove 36 is provided on one side of each of the two fixing posts 33, and a threaded groove 37 is provided at the top of each of the two fixing posts 33.

[0028] In this embodiment, the bottom of the extension plate 31 is fixedly connected to the top of the liquid inlet plate 15. A filter screen 17 is snapped into the bottom of the liquid inlet plate 15, and two filter plates 18 are snapped into the bottom of the filter screen 17. The bottom of each of the two filter plates 18 is snapped into the filter screen 17. Pressing the extension plate 31 will make the components at the bottom snap into each other more tightly, and make the seal between the components tighter. Four slots 32 are provided in a ring shape on the outer side of the extension plate 31. The bottom of the two fixing posts 33 is rotatably connected to the top of the connecting plate 14 through a rotating part, so that the fixing posts 33 can rotate 90 degrees. The top outer side of the two fixing posts 33 is snapped into the inside of the two slots 32. A sliding groove 36 is provided on the top of the fixing posts 33. A sliding block 34 is slidably connected inside the sliding groove 36. The middle part of the sliding block 34 slides up and down inside the sliding groove 36. The two sides of the sliding block 34 are inside the sliding groove 36. The width of the section can restrict the sliding block 34 from sliding out from the left and right, so that the sliding block 34 can only move up and down. The two sides of the sliding block 34 will also contact the top of the extension plate 31. The downward movement of the sliding block 34 will push the extension plate 31 downward. The top of the fixing column 33 has a threaded groove 37, and the threaded groove 37 is connected to the threaded rod 35. The threaded groove 37 communicates with the sliding groove 36. When the threaded rod 35 rotates downward, the threaded rod 35 will contact the top of the sliding block 34, so that the sliding block 34 moves downward. The downward movement of the sliding block 34 will push the position of the extension plate 31 to move down, thereby making the connection between the bottom locking components of the extension plate 31 tighter and enhancing the sealing between the components. Rotating the threaded rod 35 at the top in the opposite direction can release the pressure of the bottom of the sliding block 34 on the top of the extension plate 31, thereby relieving the pressure of the extension plate 31 on the bottom component.

[0029] Example 2

[0030] like Figure 1 - Figure 8As shown, the fixing mechanism 2 includes two fixing columns 21. A fixing block 22 is fixedly connected to one side of the top of each fixing column 21. A rotating column 23 is provided on both sides of each fixing block 22. A connecting piece 24 is rotatably connected to one end of each rotating column 23. A fixing plate 25 is fixedly connected to the end of each rotating column 23 away from the connecting piece 24. A fixing hole 26 is provided at the bottom of each fixing plate 25. A sliding rod 28 is provided on one side of the fixing block 22. Two springs 27 are fixedly connected to one side of the sliding rod 28.

[0031] In this embodiment, the bottoms of the two fixed posts 21 are rotatably connected to the top sides of the connecting plate 14 via rotating parts, allowing the fixed posts 21 to rotate freely. The outer tops of the two fixed posts 21 are engaged with the inside of the two slots 32. A fixed block 22 is fixedly connected to the top of the fixed posts 21. Connecting pieces 24 are provided on both sides of the top of the fixed posts 21. The bottoms of the two connecting pieces 24 are rotatably connected to the top of the extension plate 31. One end of the rotating post 23 is rotatably connected to the connecting piece 24. A fixed plate 25 is fixedly connected to the end of the rotating post 23 away from the connecting piece 24. The bottom of the fixed plate 25 is slidably engaged with the inside of the fixed block 22. One side of the bottom of the fixed plate 25 is inclined. A spring 27 is fixedly connected to one side of the sliding rod 28. When the fixed plate 25 slides into the fixed block 22, the inclined surface of the fixed plate 25 contacts one side of the sliding rod 28, making... When the spring 27 is compressed, the sliding rod 28 moves outward. A fixing hole 26 is provided on one side of the fixing plate 25. As the fixing plate 25 goes deeper, until the outer side of the fixing hole 26 contacts the outer side of the sliding rod 28, the spring 27 releases its elasticity, pushing the sliding rod 28 into the fixing hole 26, thereby restricting the position of the fixing plate 25 and preventing it from moving. The inability of the fixing plate 25 to move restricts the bottom assembly of the extension plate 31 from moving up and down, preventing the bottom assembly of the extension plate 31 from falling out and affecting the filtration effect. The two sets of settings also make the mechanism more stable. When it is necessary to release the limit, simply pull the sliding rod 28 outward, causing the spring 27 on one side of the sliding rod 28 to contract, thereby causing one side of the sliding rod 28 to disengage from the fixing hole 26. Then pull the fixing plate 25 upward to easily release the limit.

[0032] Working principle: First, the inlet plate 15, filter screen 17, and filter plate 18 are stacked. For every two layers of filter plates 18 stacked, the inlet plate 15 is placed on top, and a layer of filter screen 17 is placed in the middle of each layer. The stacking uses an embedded connection, and the embedded parts are equipped with annular rubber rings to increase sealing. The center of each layer forms a sealed infusion pipe through stacking. Multi-layer filtration ensures filtration accuracy. Then, the two side fixing columns 21 are rotated to contact the inside of the two slots 32. Next, the rotating column 23 is rotated so that the bottom of the fixing plate 25 engages with the inside of the fixing block 22. This engagement prevents the rotating column 23 and the connecting piece 24 from moving. The top of the extension plate 31 is fixedly connected to the bottom component of the extension plate 31, preventing it from detaching. Then, the two fixing posts 33 on both sides are rotated to contact the inside of the two slots 32. Next, the threaded rod 35 at the top of the fixing post 33 is rotated, causing it to move downwards. This movement pushes the sliding block 34 downwards, bringing it into contact with the top of the extension plate 31 on both sides. As the threaded rod 35 rotates continuously, the sliding blocks 34 on both sides continuously press downwards against the extension plate 31, causing the extension plate 31 to press downwards against the bottom component, making the connection of the bottom component of the extension plate 31 tighter and increasing the seal. At this point, the outer casing 11 is fixedly connected to the support plate 13 using fasteners. Then, the cleaning fluid to be filtered is injected through the inlet pipe 12. The cleaning solution is injected into the housing 11 and immediately comes into contact with the top inlet plate 15. The inlet plate 15 has inlet holes 16 on its side. The cleaning solution enters through the inlet holes 16 on the top and side of the inlet plate 15, flows downwards through the inlet plate 15, passes through the filter screen 17 for the first filtration, then through the filter plate 18 for the second filtration, and then through the filter screen 17 at the bottom of the filter plate 18 for the third filtration. The bottom of the filter screen 17 also has a filter plate 18. The filtered cleaning solution flows out through the outlet holes 19 on the inner side of the filter plate 18. The flowing cleaning solution enters the bottom outlet pipe 101 through the infusion pipe in the center of each layer, and is then discharged for use. The four support pillars 10 at the bottom of the support plate 13... 2. The overall structure is supported, making the filtration process smoother. When the filter plate 18 needs to be cleaned, simply open the outer shell 11 and gently pull the sliding rods 28 on both sides outwards by hand, so that one side of the sliding rod 28 disengages from the inside of the fixing hole 26. Then, push the fixing plate 25 upwards by hand, so that the limiting of the fixing plate 25 and the fixing block 22 is released first. Finally, rotate the fixing column 1 21 ninety degrees, and then rotate the threaded rod 35 at the top of the fixing column 2 33 in the opposite direction by hand, so that the sliding block 34 no longer presses the extension plate 31 downwards. Then rotate the fixing column 2 33 ninety degrees, so that the two sides of the sliding block 34 no longer touch the top of the extension plate 31. At this time, the bottom component of the extension plate 31 can be easily separated, making it convenient to clean.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
