[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figures 1-5 As shown, this utility model provides a convenient connection structure for a split-type vacuum filter, including a filter base 7. Openings 14 are provided through both sides of the filter base 7. Two placement frames 15 are slidably installed inside the filter base 7. A liquid outlet 16 is provided through the bottom surface of the placement frame 15. A filter element 17 is provided inside the placement frame 15. Protective frames 8 are fixedly installed on both sides of the filter base 7. A threaded hole 20 is provided through the inner side wall of the protective frame 8. A threaded rod 21 is threadedly connected inside the threaded hole 20. A handle 22 is fixedly installed at one end of the threaded rod 21. A push block 23 is fixedly installed at the end of the threaded rod 21 away from the handle 22. A protective door 19 is hinged to the top of the protective frame 8.

[0028] The overall effect of Embodiment 1 is that when the filter element 17 needs to be replaced, the operator rotates the two handles 22 respectively. The handles 22 drive the threaded rod 21 to rotate, thereby causing the threaded rod 21 to move along the threaded hole 20, which in turn drives the push block 23 to move. At this time, one push block 23 pushes the placement frame 15 to move, while the other push block 23 moves as follows: Figure 3 As shown, when the pusher 23 pushes another protective frame 8 into the filter seat 7, the filter element 17 inside the protective frame 8 can continue to filter. At this time, the staff can pull the protective door 19 to open the protective frame 8 and pull out the filter element 17 for replacement, which improves the filtration efficiency.

[0029] Example 2, as Figures 1-5 As shown, a connecting plate 9 is fixedly installed on the outer wall of the filter base 7. The top and bottom of the connecting plate 9 are provided with slots 28. The inner side wall of the slot 28 is provided with a limiting groove 29. A spring 30 is fixedly installed on the inner wall of the limiting groove 29. A locking block 31 is fixedly installed on one end of the spring 30. A connecting rod 32 is fixedly installed on one end of the locking block 31. One end of each of the two connecting rods 32 passes through the two limiting grooves 29 and is fixedly installed with a pull plate 33.

[0030] Furthermore, a plug plate 24 is slidably installed inside the slot 28, and a slot 25 is opened on the outer wall of the plug plate 24. A control plate 26 is fixedly installed at one end of the plug plate 24.

[0031] Furthermore, a sealing ring 27 is fixedly installed on the outer wall of the control panel 26, and sealing grooves 18 are provided at the top and bottom of the filter seat 7. During installation, the sealing ring 27 enters the inner wall of the sealing groove 18, which improves the sealing performance and prevents water leakage.

[0032] Furthermore, the inner walls of the two control panels 26 are respectively fixedly installed with the raw liquid tank 10 and the filter body 3, and the outer wall of the filter body 3 is connected and fixedly installed with a vacuum pipe 4.

[0033] Furthermore, a liquid outlet pipe 5 is fixedly installed at the bottom of the filter body 3, and a valve 6 is provided on the outer wall of the liquid outlet pipe 5. The operator connects the vacuum pump's suction pipe to the vacuum pipeline 4, and the filtered solution flows into the collection device from the liquid outlet pipe 5 through the valve 6.

[0034] Furthermore, a base 1 is provided on the outer wall of the filter body 3, and three evenly distributed support frames 2 are fixedly installed at the bottom of the base 1 to provide support for the entire device.

[0035] Furthermore, a vertical plate 12 is fixedly installed on the top of the base 1. A fixing groove 34 is opened on the top of the vertical plate 12. A magnet 35 is fixedly installed on the inner wall of the fixing groove 34. An iron block 36 enters the fixing groove 34 and is attracted to the surface of the magnet 35. The vertical plate 12 can then provide support for the original liquid tank 10.

[0036] Furthermore, a fixing ring 11 is fixedly installed on the outer wall of the raw liquid tank 10, a placement plate 13 is fixedly installed on the outer wall of the fixing ring 11, and an iron block 36 is fixedly installed at the bottom of the placement plate 13.

[0037] Furthermore, the outer wall of the insert plate 24 fits against the inner wall of the slot 28, and the inner wall of the slot 25 fits against the outer wall of the block 31. When the block 31 enters the slot 25, the insert plate 24 can be fixed in place to prevent shaking and affect the sealing performance.

[0038] The effect achieved by the entire embodiment 2 is that, during connection, the operator can conveniently place the original liquid tank 10 and the filter body 3 on the top and bottom of the filter base 7, insert the two insert plates 24 into the slot 28, and the insert plates 24 contact the inclined surface of the locking block 31. The locking block 31 is squeezed into the limiting groove 29 and the spring 30 is compressed. When the slot 25 moves to the side of the locking block 31, the locking block 31 enters the slot 25 under the elastic force of the spring 30. In this way, the installation can be completed, which improves the connection efficiency.

[0039] Working principle: During connection, the operator places the raw liquid tank 10 and the filter body 3 conveniently on the top and bottom of the filter base 7. Two insert plates 24 are inserted into the slots 28, and the insert plates 24 contact the inclined surfaces of the locking blocks 31. The locking blocks 31 are squeezed into the limiting groove 29, and the spring 30 is compressed. When the locking groove 25 moves next to the locking blocks 31, the locking blocks 31 enter the locking groove 25 under the elastic force of the spring 30, thus completing the installation and improving the connection efficiency. At the same time, the iron block 36 enters the fixing groove 34 and is attracted to the surface of the magnet 35. The upright plate 12 can then provide support for the raw liquid tank 10. At this time, the solution inside the raw liquid tank 10 enters the filter base 7 and contacts the filter element 17. After being filtered by the filter element 17, it enters the filter body 3. The vacuum pump's suction pipe is connected to the vacuum pipe 4. The filtered solution flows into the collection device from the outlet pipe 5 through the valve 6. When filter element 17 needs to be replaced, the operator rotates the two handles 22 respectively. The handles 22 drive the threaded rod 21 to rotate, which in turn causes the threaded rod 21 to move along the threaded hole 20, thereby causing the push block 23 to move. At this time, one push block 23 pushes the placement frame 15 to move, while the other push block 23 moves as if... Figure 3 As shown, when the pusher 23 pushes another protective frame 8 into the filter seat 7, the filter element 17 inside the protective frame 8 can continue to filter. At this time, the staff can pull the protective door 19 to open the protective frame 8 and pull out the filter element 17 for replacement, which improves the filtration efficiency.

[0040] 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.
