A first filter screen 13 and a second filter screen 14 are fixedly installed on opposite sides of the two insert plates 19, respectively. A connecting groove 27 is opened on the outer wall of both the first filter screen 13 and the second filter screen 14. A limiting groove 28 is opened on the inner wall of the housing 1. An electromagnet 29 is fixedly installed on the inner wall of the limiting groove 28. A spring 30 is fixedly installed on the outer wall of the electromagnet 29. A connecting block 31 is fixedly installed at one end of the spring 30.

[0024] The overall effect of Embodiment 1 is as follows: when impurities clog the first filter screen 13, the operator activates the electromagnet 29, and the iron connecting block 31 is attracted away from the connecting groove 27 and enters the limiting groove 28. The spring 30 is compressed, and then the operator pushes the second filter screen 14 into the housing 1. When the connecting groove 27 of the second filter screen 14 moves to the side of the limiting groove 28, the operator closes the electromagnet 29. The elastic force of the spring 30 pushes the connecting block 31 into the connecting groove 27, fixing the second filter screen 14. At this time, the first filter screen 13 leaves the housing 1 from the opening 9. The operator rotates the handle 26, and the threaded rod 24 rotates. The threaded rod 24 moves along the threaded hole 22, thereby driving the locking block 25 to leave the locking groove 20. At this time, the operator can pull out the insert plate 19 to clean the first filter screen 13. In this way, cleaning can be carried out without stopping the machine, which improves the filtration efficiency.

[0025] Example 2, as Figures 1-4As shown, further, the top of the box 1 is provided with a top cover 3, both ends of the top cover 3 are fixedly installed with a moving plate 6, both sides of the box 1 are fixedly installed with a fixed plate 4, the top of the fixed plate 4 is fixedly installed with an electric telescopic rod 5, and the telescopic end of the electric telescopic rod 5 is fixedly connected with the bottom of the moving plate 6.

[0026] Further, the bottom of the top cover 3 is fixedly installed with a sealing ring 11, and the top of the box 1 is provided with a sealing groove 10.

[0027] Further, the inner wall of the box 1 is fixedly installed with a funnel 16, and the bottom of the funnel 16 is provided with a chromatographic column 17.

[0028] Further, the top of the top cover 3 is fixedly installed with a feeding pipe 7, and the top of the feeding pipe 7 is provided with a pipe cover 8.

[0029] Further, the bottom of the box 1 is fixedly installed with a support frame 2, and the inner wall of the box 1 is fixedly installed with two placing plates 15, which are used to support the first filter screen 13 and the second filter screen 14.

[0030] Further, the outer walls of the connecting plate 12, the first filter screen 13 and the second filter screen 14 are in close contact with the inner wall of the opening 9, so as to prevent the epoxy resin from leaving the box 1 from the opening 9 during filtration.

[0031] The effect achieved by the whole embodiment 2 is that when the top cover 3 is closed, the staff starts the electric telescopic rod 5, the telescopic end of the electric telescopic rod 5 is retracted, driving the top cover 3 to descend, when the bottom of the top cover 3 is in close contact with the top of the box 1, the sealing ring 11 enters the sealing groove 10, improving the sealing property and preventing the dust from the outside into the box 1.

[0032] Working principle: when using, the staff opens the pipe cover 8, and the epoxy resin is poured into the box body 1, the epoxy resin contacts the first filter screen 13, the impurities in the interior are left on the top of the first filter screen 13, and the filtered epoxy resin enters the chromatographic column 17 from the hopper 16 and is filtered. When the impurities block the first filter screen 13, the staff starts the electromagnet 29, the iron connecting block 31 is attracted to leave the connecting slot 27 and enter the limiting slot 28, the spring 30 is compressed, then the staff pushes the second filter screen 14, and the second filter screen 14 enters the box body 1, when the connecting slot 27 of the second filter screen 14 moves beside the limiting slot 28, the staff closes the electromagnet 29, the elastic force of the spring 30 pushes the connecting block 31 into the connecting slot 27, and the second filter screen 14 is fixed, at this time the first filter screen 13 leaves the box body 1 from the opening 9, the staff rotates the handle 26, the threaded rod 24 rotates, the threaded rod 24 moves along the threaded hole 22, and then drives the clamping block 25 to leave the clamping slot 20, at this time the staff can pull out the plug-in board 19, and the first filter screen 13 is cleaned, so that the cleaning can be carried out without stopping the machine, and the filtering efficiency is improved. When cleaning the box body 1, the staff starts the electric telescopic rod 5, the telescopic end of the electric telescopic rod 5 is stretched, and the top cover 3 is pushed up, at this time the cleaning can be started, when the top cover 3 is closed, the staff starts the electric telescopic rod 5, the telescopic end of the electric telescopic rod 5 is retracted, and the top cover 3 is driven to descend, when the bottom of the top cover 3 is attached to the top of the box body 1, the sealing ring 11 enters the sealing groove 10, the sealing property is improved, and the dust outside is prevented from entering the box body 1.
