DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The utility model provides a technical solution: a filtering device for formaldehyde production, including a filter cartridge 1, a liquid inlet pipe 2, an electric telescopic rod 3, a push plate 4, a stabilizing plate 5, a fixed cartridge 6, a sealing gasket 7, a filter screen 8, a mounting mechanism 9, a fixed column 10, a movable column 11, a fixed rod 12, a fixed block 13, a connecting plate 14, a connecting bolt 15, a mounting column 16, a mounting plate 17 and a positioning plate 18.

[0032] When using the formaldehyde production filter, Figure 1 , Figure 2 and Figure 4 As shown, the right end of the filter cartridge 1 is fixedly connected with a liquid inlet pipe 2, and the liquid inlet pipe 2 is connected to an external loading cylinder. The formaldehyde scavenger liquid raw material of the loading cylinder enters the filter cartridge 1 through the liquid inlet pipe 2, and is filtered by the filter screen 8 placed in the middle of the fixed cylinder 6. The filtered liquid raw material flows out downward and is collected in an external container for further processing. When filtering the liquid raw material, the electric telescopic rod 3 installed at the upper end of the filter cartridge 1 is started, and the electric telescopic rod 3 drives the push plate 4 to move up and down slowly inside the filter cartridge 1. The push plate 4 is closely arranged on the inner side of the filter cartridge 1. By moving the push plate 4 downward, the pressure inside the filter cartridge 1 can be increased, so that the liquid raw material can be filtered through the filter screen 8 more quickly, which greatly improves the actual filtering efficiency. At the same time, the push plate 4 drives the stabilizing plate 5 to slide between the filter cartridge 1 during the movement, so that the push plate 4 is more stable during the movement.

[0033] When the filtration process is completed, Figure 3 , Figure 5 and Figure 6As shown, turn off the power supply, the connecting plate 14, the connecting bolt 15, the mounting column 16 and the mounting plate 17 are all arranged at equal angles at the edge of the fixed cylinder 6, and the connecting bolt 15 threadedly connected to the connecting plate 14 is rotated, so that the connecting bolt 15 and the mounting column 16 are rotated, thereby driving the mounting column 16 and the connecting plate 14 to slide, and at this time, the mounting column 16 drives the mounting plate 17 to disengage from the positioning plate 18, and at the same time, the mounting plate 17 is disengaged from the fixed cylinder 6, thereby releasing the limit between the fixed cylinder 6 and the filter cylinder 1, and then the fixed cylinder 6 is pulled downward to remove the fixed cylinder 6 from the lower end of the filter cylinder 1, so as to facilitate the full cleaning of the inner side of the filter cylinder 1 to prevent residue;

[0034] In addition, in combination with the setting of the mounting mechanism 9, the mounting mechanism 9 includes fixed columns 10 fixedly connected to the left and right ends of the filter screen 8, a movable column 11 rotatably connected to the middle of the fixed column 10, a fixed rod 12 fixedly connected to the side of the lower end of the movable column 11, and a fixed block 13 for limiting. By rotating the movable column 11, the movable column 11 and the fixed column 10 rotate. At this time, the torsion spring at the connection between the movable column 11 and the fixed column 10 is elastically deformed, and the movable column 11 drives the fixed rod 12 to move, so that the fixed rod 12 is disengaged from the fixed block 13, thereby releasing the limit between the filter screen 8 and the fixed cylinder 6. At the same time, the diameter of the filter screen 8 is smaller than the spacing between the fixed blocks 13 on the left and right sides. Then, the filter screen 8 is pulled upward, and the filter screen 8 does not interfere with the fixed block 13. The filter screen 8 can be removed from the fixed cylinder 6, which is convenient for cleaning the filter screen 8 and cleaning impurities at the filtration site to prevent the filter screen 8 from being blocked.
