A solenoid valve is provided on the discharge pipe 6. A bracket 9 is fixed to the top of the right side of the filter tank 2. A first curved plate 8 is fixed on the butt joint pipe 7. Both ends of the first curved plate 8 are fixed on the bracket 9, which improves the stability of the first curved plate 8 and the bracket 9 and prevents them from falling. Two groups of funnels 14 used in conjunction with the butt joint pipe 7 are sequentially provided on the first curved plate 8 along the front and rear directions. A filter plate 16 is embedded in each group of funnels 14, and a filter paper 15 is placed on the filter plate 16.

[0024] Reference Figure 2 and Figure 3, an automatic conversion component is provided on the bracket 9, the first curved plate 8 and the filter tank 2, and the automatic conversion component includes a motor 10 embedded in the bracket 9, the output shaft of the motor 10 is fixed to the flip frame 11, both ends of the flip frame 11 are inserted with a docking seat 12 and the funnel 14 is embedded in the docking seat 12 away from the end of the flip frame 11, and multiple groups of arc-shaped rubber strips 13 are symmetrically provided on the top and bottom of both ends of the flip frame 11, and a strip groove for use with the arc-shaped rubber strip 13 is opened in the docking seat 12. By setting the arc-shaped rubber The rubber strip 13 and the strip groove improve the stability of the docking seat 12 and the flip frame 11 when plugging together to avoid separation. One group of funnels 14 is located directly below the discharge pipe 6, and the bottom end of one group of funnels 14 is attached to the docking pipe 7. The left side of the first curved plate 8 is fixed with a second curved plate 17 and the right side of the second curved plate 17 is attached to one end of the docking seat 12. The top of the right side of the second curved plate 17 is fixed with an arc-shaped beading 18 and the bottom of the arc-shaped beading 18 is attached to the top of the docking seat 12. The second curved plate 17 and The lengths of the curved beading 18 are the same, and the length of the first curved plate 8 is greater than the length of the second curved plate 17 and the curved beading 18. The different length designs make it easier for the user to separate the docking seat 12 from the flip frame 11. A docking shaft 19 is rotatably installed on the top of the inner cavity of the filter tank 2. A plurality of strip fan blades 20 used in conjunction with the docking tube 7 are evenly fixed on the docking shaft 19. An angle encoder 21 is provided at one end of the docking shaft 19, and the angle encoder 21 is fixed to the filter tank 2 through a support rod. By setting an automatic conversion component and adopting an automatic detection method, when the funnel 14 is blocked, the user can promptly know and replace another set of funnels 14 for filtering in time.

[0025] In the present invention, the user turns on the air pump 3 and the solenoid valve through the controller. At this time, the air pump 3 extracts the gas in the filter tank 2 and keeps the interior thereof in a negative pressure state. At this time, the preparation liquid for preparing methyl ethyl ketone oxide in the storage barrel 5 can fall onto the filter paper 15 in the funnel 14 through the discharge pipe 6. At this time, the filter tank 2 can pull the liquid so that the preparation liquid can quickly enter the filter tank 2 through the filter plate 16 and impact the strip fan blades 20, thereby driving the docking shaft 19 to rotate. At this time, the angle encoder 21 monitors the rotation speed in real time. If the funnel 14 is blocked, the strip fan blades 20 and the docking shaft 19 rotate slowly or do not rotate. At this time, the angle encoder 21 can detect it in time and send the information to the controller. The controller promptly knows that the funnel 14 is clogged. At this time, the controller can quickly control the solenoid valve to close, and synchronously turn on the motor 10 and the alarm. The alarm buzzes to remind the user that the funnel 14 is clogged, and the motor 10 can drive the flip frame 11 to rotate, thereby quickly rotating the other set of funnels 14 onto the docking tube 7, and synchronously moving the clogged funnel 14 to the outside. At this time, the user only needs to pull the docking seat 12 away from the flip frame 11 to clean the clogged funnel 14. By adopting the automatic detection method, the user can promptly know when the funnel 14 is clogged and promptly replace another set of funnels 14 for filtering. The alternating use method avoids the user having to stop the machine for a long time to clean the funnel 14, which greatly improves the overall filtration efficiency of the device.
