[0004] The purpose of the present invention is to provide a kind of waterproof ventilation pipeline filter device, to solve the above-mentioned background technology, when the original filter device replaces the filter screen, most of the filter devices are first unloaded from the inside of the ventilation pipeline, and then removed from the ventilation pipeline. Pull out the filter screen from the side, which increases the operating procedures of the staff and reduces the convenience of the filter device. The new problem is that the filter screen is bound to be corroded by the water vapor in the air during use, which will lead to the aging of the filter screen and eventually cause the filter screen to be damaged. Reduced service life or poor filter performance

Embodiment 1
[0026] see Figure 1-3 , the present invention provides a technical solution: a waterproof and ventilation pipeline filter device, including a dust removal box 11, an electric box 12, a filter screen 13, a handle 14, a buckle 15, an outer frame 16, a first rubber pad 17, a Page 18 and the second rubber pad 19, the top of the dust removal box 11 is provided with a power box 12, the power box 12 is welded with the dust removal box 11, and the middle position of the right end of the dust removal box 11 is provided with a handle 14, and the handle 14 is connected with the dust removal box 11 Fixedly connected, the inside of the dust removal box 11 is provided with a filter screen 13, the filter screen 13 is fixedly connected with the dust removal box 11, the front surface inner wall of the dust removal box 11 is provided with a second rubber pad 19, and the second rubber pad 19 is fixed to the dust removal box 11 connection, the left side of the second rubber pad 19 is provided wi...
Embodiment 2
[0042] The difference from Example 1 is that the filter screen 13 is coated with a waterproof layer, and the preparation method of the waterproof layer is:
[0043] Take the following raw materials by weight for each component: 19 parts of acrylate, 7 parts of epoxy resin, 5 parts of triethylhexyl phosphoric acid, 1 part of dimethyl sulfoxide, 10 parts of silicon acrylic emulsion, 1 part of o-phenylphenol , 3 parts of propylene glycol methyl ether acetate, 1 part of urea, and 20 parts of deionized water.
[0045] S2. Preparation of waterproof material: add o-phenylphenol, propylene glycol methyl ether acetate, urea, and dimethyl sulfoxide to the organic solvent in S1 in sequence, stir evenly, heat the temperature to 72° C., and keep it warm for 1 hour;
[0046] S3, cleaning: c...

Abstract
The invention discloses a waterproof ventilation pipeline filter device comprising a dust removal box, an electric power box, a filter screen, a grip, a clamp buckle, an outer frame, a first rubber pad, a hinge and a second rubber pad. The top of the dust removal box is provided with the electric power box; the electric power box is welded with the dust removal box; the grip is arranged at the middle position of the right end of the dust removal box and is fixedly connected with the dust removal box; a filter screen is arranged inside the dust removal box and is fixedly connected with the dustremoval box. When the filter screen is necessary to replace, the filter screen is divorced from a clamp slot by the clamp buckle, and the outer frame rotates to the outside to draw out a waste filterscreen, a new filter screen is placed on the surface of the second rubber pad of the dust removal box, and then the outer frame rotates in the direction of the dust removal box with the cooperation of the hinge, so that the first rubber pad makes close contact with the second rubber pad, and finally the clamp buckle is inserted into the clamp slot to fix the filter screen; therefore, operation steps of the staff can be reduced, and the functionality of the filter device is increased; the filter screen is coated with a waterproof layer, and the filter screen can be prevented from being corroded by water vapor.
Description
technical field [0001] The invention belongs to the technical field of ventilation pipelines, and in particular relates to a waterproof ventilation pipeline filtering device. Background technique [0002] The filter device has multiple functions such as dust removal, mildew prevention, and cleaning. It can control air pollution in indoor ventilation ducts, effectively purify indoor air, and protect the indoor environment. [0003] When replacing the filter screen of the original filter device, most of the filter device is first unloaded from the inside of the ventilation pipeline, and then the filter screen is pulled out from the side, which increases the operating procedures of the staff and reduces the convenience of the filter device. The filter screen is bound to be corroded by the water vapor in the air during use, which will lead to aging and defect of the filter screen, which will eventually lead to a shortened service life of the filter screen or poor filtering effec...
