The dust collecting assembly 3 is arranged at the bottom of the mounting frame 1, and the dust collecting assembly 3 is connected to the inside of the mounting frame 1. The driving member 22 drives the scraper 21 to move on the dust-proof net 11, and the dust on the air inlet surface of the dust-proof net 11 is directly scraped off and collected in the dust collecting assembly 3. This facilitates the cleaning of the dust-proof net 11 during the operation of the equipment, thereby achieving the effect of improving the working efficiency of the drying equipment.

[0044] The installation frame 1 in this embodiment is rectangular, and the driving member 22 includes a threaded rod 221, a mounting plate 222, and a driving motor 223. The threaded rod 221 passes through both ends of the installation frame 1 along the central axis of the length direction of the installation frame 1 and is rotatably connected to the installation frame 1. The middle part of the mounting plate 222 is threadedly connected to the threaded rod 221. Both ends of the mounting plate 222 are respectively provided with guide members 4, which limit the movement of the mounting plate 222 along the length direction of the threaded rod 221.

[0045] Start the drive motor 223, which drives the threaded rod 221 to rotate. The rotation of the threaded rod 221 drives the mounting plate 222 to move along the length direction of the threaded rod 221 under the guidance of the guide member 4. The movement of the mounting plate 222 drives the scraper 21 to move, thereby driving the scraper 21 to move on the dustproof net 11, thereby achieving the effect of scraping off the dust on the dustproof net 11.

[0046] The guide member 4 in this embodiment is a guide rod 41 , and the guide member 4 in other embodiments may be a combination of a guide block and a guide groove.

[0047] The guide rod 41 is fixedly connected to the mounting frame 1 , and the guide rod 41 is arranged parallel to the guide rod 41 , and the mounting plate 222 is passed through the guide rod 41 . In this embodiment, two guide rods 41 are arranged, and the two guide rods 41 are symmetrically arranged about the threaded rod 221 .

[0048] By limiting the position of the guide rod 41 , the mounting plate 222 can only move along the length direction of the threaded rod 221 . Meanwhile, the two guide rods 41 symmetrically arranged with respect to the threaded rod 221 make the guiding of the guide rod 41 more stable.

[0049] Reference Figure 2 and Figure 3 The scraper 21 includes a fixed end 211, an abutting end 212 and a spring 213. The fixed end 211 is fixedly connected to the side of the mounting plate 222 close to the dustproof net 11, the abutting end 212 is sleeved on the fixed end 211, the spring 213 is installed between the abutting end 212 and the fixed end 211, and the spring 213 drives the abutting end 212 away from the fixed end 211. In this embodiment, a limiting block is fixedly connected to the fixed end 211, and the inner side of the abutting end 212 abuts on the limiting block to prevent the abutting end 212 from detaching from the fixed end 211.

[0050] The spring 213 abuts the abutting end 212 so that the abutting end 212 can be stably attached to the dustproof net 11. At the same time, the abutting end 212 also has a certain amount of contraction to prevent the abutting end 212 from directly damaging the dustproof net 11 when the dustproof net 11 is impacted.

The dust collecting member 31 is connected with the collecting member 32. The dust scraped by the scraper 21 is sucked by the dust collecting member 31 and then collected in the collecting member 32 to prevent the dust scraped by the scraper 21 from floating randomly.

[0052] The dust suction member 31 in this embodiment includes a fan 311 and a drainage pipe 312. The fan 311 is fixedly connected to the bottom of the installation frame 1, and the drainage pipe 312 is attached to the outside of the installation frame 1. The air inlet of the fan 311 is connected to the drainage pipe 312, and the air outlet of the fan 311 faces the collecting member 32. The installation frame 1 is provided with a dust suction hole 14, which is located on the air inlet side of the dustproof net 11. The dust suction hole 14 is connected to the drainage pipe 312, so that the dust scraped from the dustproof net 11 can be sucked into the drainage pipe 312 through the dust suction hole 14.

[0057] The collecting filter bag 322 is installed between the limiting ring 321 and the clamping ring 324. The baffle 325 and the compression spring 326 are used to drive the clamping ring 324 to move along the installation rod 323 toward the limiting ring 321, so that the collecting filter bag 322 is compressed, thereby avoiding the possibility of the collecting filter bag 322 detaching from the limiting ring 321.

[0058] The implementation principle of a vertical dust screen 11 provided with a back-blowing device in an embodiment of the present application is as follows: when the detection probe 13 of the pressure difference meter 12 detects that the pressure difference on both sides of the dust screen 11 is large, the drive motor 223 is started, and the drive motor 223 drives the threaded rod 221 to rotate. The rotation of the threaded rod 221 drives the mounting plate 222 to move along the length direction of the threaded rod 221 under the guidance of the guide rod 41. The movement of the mounting plate 222 drives the scraper 21 to move, thereby scraping off the dust blocked on the air inlet side of the dust screen 11.

[0059] At the same time, the fan 311 is started, and the air inlet of the fan 311 sucks the dust through the drainage pipe 312 and the dust suction hole 14, and then discharges it into the collection filter bag 322, completing the collection of the hanging dust. It is convenient to start the drive motor 223 and the fan 311 to clean the dustproof net 11 during the operation of the equipment, avoiding the equipment shutdown caused by the cleaning of the dustproof net 11, thereby achieving the effect of improving the working efficiency of the equipment.
