DETAILED DESCRIPTION
[0021] 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.
[0022] See also Figures 1-5 In this embodiment: a dustproof structure includes a dust cover 1 and a dust collecting pipe 2, please refer toFigure 1 and Figure 2 The dust cover 1 includes a cover body 11 and an air suction cover 12. The cover body 11 is fixedly installed on the top of the feeding port 4, and the air suction cover 12 is fixedly installed on the top of the cover body 11. The air inlet of the air suction cover 12 is connected to the interior of the cover body 11. A rectangular feeding port is arranged on the front of the cover body 11. When raw materials are put into the feeding port 4, the raw materials can be put in from the feeding port on the front of the cover body 11. A row of door curtains 13 are installed on the top edge of the feeding port. The cover body 11 covering the feeding port 4 can block the raw material dust and prevent the raw material dust from flying around, and the door curtain 13 can cover the feeding port of the cover body 11 to avoid dust from flying out from the feeding port on the front of the cover body 11 as much as possible.
[0023] See also Figure 1 and Figure 3 The dust collecting pipe 2 includes a first Y-shaped pipe 21, a second Y-shaped pipe 22 and two first connecting pipes 23. The main pipe of the first Y-shaped pipe 21 is connected to the air outlet of the suction hood 12 through the second connecting pipe 3. The main pipe end of the second Y-shaped pipe 22 is equipped with an induced draft fan 5. One end of the two first connecting pipes 23 is respectively connected to the two branch pipes of the first Y-shaped pipe 21 through a flange, and the other end of the two first connecting pipes 23 is respectively connected to the two branch pipes of the second Y-shaped pipe 22 through a flange. The connection between the first connecting pipe 23 and the first Y-shaped pipe 21 and the connection between the first connecting pipe 23 and the second Y-shaped pipe 22 are both equipped with sealing rings. By controlling the induced draft fan 5 to continuously draw air outwards, the dust floating in the dust cover 1 can be sucked into the dust collecting pipe 2, thereby further preventing dust from flying. Valves 28 are installed on the two branch pipes of the first Y-shaped pipe 21 and the two branch pipes of the second Y-shaped pipe 22. The valve 28 adopts a butterfly valve.
[0024] See also Figure 4 and Figure 5 The two first connecting tubes 23 are both bellows, and a mesh bag 24 is arranged inside the first connecting tube 23.

When the first connecting tube 23 is installed, the bag opening of the mesh bag 24 faces the first Y-shaped tube 21. After the airflow carrying dust passes through the first connecting tube 23, the dust will be retained in the mesh bag 24 for centralized recovery. When recovering the dust, the first connecting tube 23 is disassembled and the mesh bag 24 is taken out.
[0025] Working principle and usage process of the present utility model: When this dust-proof structure is in use, turn on the induced draft fan 5. After the feed raw materials are put into the feeding port 4 from the feeding port on the front of the cover body 11, the scattered dust will be blocked by the cover body 11 and the curtain 13, thereby preventing the dust from spreading into the air. At the same time, under the action of the induced draft fan 5, the dust in the cover body 11 will be sucked into the dust collection pipe 2. After the airflow containing dust passes through the first connecting pipe 23, the dust will be left in the mesh bag 24 for centralized collection. When recovering this dust, first close the valves 28 at both ends of one of the first connecting pipes 23 to make this first connecting pipe 23 temporarily airtight, then remove this first connecting pipe 23, take out the mesh bag 24 filled with dust, then install an empty mesh bag 24 back into the first connecting pipe 23, finally install this first connecting pipe 23 back and open the valves 28 at both ends of it, and then repeat the operation to take out the mesh bag 24 in the other first connecting pipe 23. When recovering dust, the induced draft fan 5 does not need to be turned off, and the dust collection pipe of this dust-proof structure can work continuously.
