A pressure plate 4 is arranged on one side of the bracket 3, and a fixing component 5 is arranged between the pressure plate 4 and the inner wall of the box body 1. The upper and lower ends between the box body 1 and the movable door 2 are both provided with hinge components 14. When in use, due to the setting of the fixing component 5 and the hinge component 14, the movable door 2 is opened and closed by The hinge assembly 14 is fixed to the main body of the box body 1, and the movable door 2 is fastened and sealed with the filter box body by fastening bolts. The filter 19 is placed on the bracket 3, and the tie rod bracket 11 is welded to the filter 19 box body. The tie rod 12 fixes the filter 19 through the tightening force between the tie rod bracket 11 and the pressure plate 4. When replacing the filter 19, first use a wrench to remove all the fastening bolts on the movable door 2, open the movable door 2, place the filter 19 on the bracket 3, connect all the tie rods 12 to the tie rod bracket 11 and the pressure plate 4, and then tighten all the tie rods 12. The rib rod 12 is fitted on the 4 sides of the entire pressure plate to play the role of overall sealing. After the filter 19 is installed, all the fasteners of the movable door 2 are tightened again. Compared with the traditional filter 19 box 1, the movable door 2 of this box 1 adopts a hinge method, which can be disassembled by one person with less effort. There is no need to directly disassemble the inspection door. The installation of the filter 19 is simple. It can be directly placed on the bracket 3 and connected to the rib rod 12 through the fixing bolt 13. This solves the problem that the filter 19 in the prior art is not sealed tightly inside the box 1 during use, and the filter box is not tightly sealed. 1 The door panel is non-movable, and the removal and tightening of the bolts are time-consuming and laborious. In the later stage, it is impossible to replace the filter element with a different specification and thickness, resulting in the need for a different filter 19 box 1, which increases the replacement cost. In addition, through the combination of the fixing component 5 and the pressure plate 4, the sealing surface is tight, and the tension rod 12 and the pressure plate 4 work together to achieve a tight overall sealing surface of the filter 19, so that the filtered airflow can be filtered through the filter 19. At the same time, a sealing plate 18 is arranged on the movable door 2 to make it tightly connected with the inside of the box 1 to ensure the sealing of its filtration.

The filter 19 is placed on the bracket 3, and the tie rod bracket 11 is welded to the filter 19 box body. The tie rod rod 12 fixes the filter 19 through the tightening force between the tie rod bracket 11 and the pressure plate 4. When replacing the filter 19, first use a wrench to remove all the fastening bolts on the movable door 2, open the movable door 2, place the filter 19 on the bracket 3, connect all the tie rods 12 to the tie rod bracket 11 and the pressure plate 4, and then tighten all the tie rods 12. Through the four surfaces of the entire pressure plate, the overall sealing effect is achieved. After the filter 19 is installed, all the fasteners of the movable door 2 are tightened again. Compared with the traditional filter 19 box 1, the movable door 2 of this box 1 adopts The hinged method can save effort for one person to disassemble the movable door 2, and there is no need to directly disassemble the inspection door. The installation of the filter 19 is simple and can be directly placed on the bracket 3 and connected to the tie rod 12 through the fixing bolts 13. This solves the problem that the filter 19 in the prior art has a loose seal inside the box body 1 during use. The door panel of the filter box body 1 is non-movable, and it is time-consuming and laborious to disassemble and tighten the bolts. Later, the filter element with different specifications and thicknesses cannot be replaced, resulting in the need for different filter 19 boxes 1, which increases the replacement cost.
