[0025] Specifically, Figure 2As shown, the exhaust pipe 5 is connected with a pressure sensor 8 for detecting the negative pressure value in the exhaust pipe 5, and the pressure sensor 8 is connected to a controller 9. The suction pipe 3 is connected with a backflush pipe connected to an air source 10, and one end of the backflush pipe 13 is connected with a control valve 11, and the control valve 11 is connected to the controller 9. The other end of the backflush pipe extends into the suction pipe 3, and one end of the backflush pipe located in the suction pipe 3 is connected with a nozzle 12. Those skilled in the art can set the number and position of the nozzles according to the area of ​​the filter screen and the spray range of the nozzles. Figure 2 The number of nozzles shown is for example only. After the filter assembly 4 is clogged, the exhaust fan 6 is still running, and the pressure value in the exhaust pipe 5 is gradually reduced. When the pressure in the exhaust pipe 5 is reduced to a set value, the controller 9 opens the control valve 11, and the gas for back-blowing the filter screen 402 flows out from the gas source 10 and blows toward the filter assembly 4 through the back-blowing pipe and the nozzle 12, thereby cleaning the filter screen 402.

[0026] Specifically, the filter assembly 4 includes a mounting ring 401 for connecting to the suction pipe 3 and a filter screen 402 installed at the bottom of the mounting ring 401. A through hole matching the inner diameter of the suction pipe 3 is opened in the middle of the mounting ring 401. The filter screen 402 includes a filter portion 4021 made of non-woven fabric and a fixing portion 4022 woven from polyester fibers. The shape of the filter portion 4021 matches the through hole. The fixing portion 4022 is connected to the outside of the filter portion 4021. A plurality of fixing holes are provided on 22, and a protective cover 4023 is provided in each of the fixing holes. The material of the protective cover 4023 is plastic or stainless steel. The protective cover 4023 can prevent the fixing hole from being torn after being subjected to force. A plurality of pins 404 are provided at the bottom of the mounting ring 401, and the pins 404 correspond to the fixing holes one by one. The protective cover 4023 is installed on the outside of the pins 404 to open the filter screen 402; a connecting component 403 connected to the suction pipe 3 is also provided on the top of the mounting ring 401.

[0027] Specifically, the pin 404 is divided into a fixed pin 4041 and a movable pin 4042. The fixed pin 4041 is fixed to the bottom of the mounting ring 401. The mounting ring 401 is provided with an adjustment groove 4011. The adjustment groove 4011 and the fixed pin 4041 are arranged alternately at equal intervals. The movable pin 4042 is slidably connected in the adjustment groove 4011. The side wall of the movable pin 4042 is provided with an extension ring 40421. The extension ring 40421 contacts the inner top wall of the adjustment groove 4011. Figure 4As shown, the diameter of the extension ring is larger than the diameter of the movable pin, and the upper end of the movable pin 4042 passes through the adjustment slot 4011 and is connected with a locking nut 405. The fixed pin 4041 is used to position the filter screen 402, and the slidable movable pin 4042 is used to tighten the filter screen 402. When installing a new filter screen 402, the filter screen 402 is first sleeved on the movable pin 4042 and the fixed pin 4041, and then the movable pin 4042 is pulled to move so that the filter screen 402 between two adjacent fixed pins 4041 is tightened. After the filter screen 402 is tightened, the locking nut 405 is tightened to fix the movable pin 4042.

[0028] Specifically, the material of the mounting ring 401 is a magnetic material, and the filter assembly 4 further includes a magnet 406, which fixes the filter screen 402 to the bottom of the mounting ring 401. The magnet 406 can be an annular magnet 406 that matches the fixing portion 4022. After the annular magnet 406 is adsorbed on the bottom of the mounting ring 401, the fixing portion 4022 is tightly fitted to the bottom of the mounting ring 401, so that there is no gap between the filter screen 402 and the mounting ring 401.

[0029] Specifically, the connecting assembly 403 includes a connecting seat 4031 arranged at the top of the mounting ring 401, the connecting seat 4031 is connected to a rotating shaft 4032, the rotating shaft 4032 is rotatably connected to a locking arm 4033, the rotating shaft 4032 is connected to a torsion spring 4034, one end of the torsion spring 4034 is connected to the connecting seat 4031, and the other end of the torsion spring 4034 is connected to the locking arm 4033, the outer wall of the suction tube 3 is provided with a locking protrusion 301, the locking arm 4033 is provided with a locking groove 40331, the locking groove 40331 is an arc-shaped groove, and the locking protrusion 301 is an arc-shaped protrusion, when the mounting ring 401 is fixed to the lower end of the suction tube 3, the locking protrusion 301 is fitted with the locking groove 40331. The upper end of the locking arm 4033 has a guide portion 40332. When the filter 402 is installed, the guide portion 40332 first contacts the locking protrusion 301. As the mounting ring 401 moves upward, the locking arm 4033 gradually opens. When the locking protrusion 301 is contained by the locking groove 40331, the locking arm 4033 is reset under the drive of the torsion spring 4034.

[0030] A specific application of this device is:

[0031] During the feeding process, the exhaust fan 6 is kept in the started state. The trace amount of floating powder generated during the feeding process is filtered by the filter assembly 4 arranged at the lower end of the suction pipe 3, and then discharged into the air through the exhaust pipe 5 and the exhaust pipe 7.

[0032] After the filter 402 is clogged, since the exhaust fan 6 is still running, the pressure value in the exhaust pipe 5 gradually decreases. When the pressure in the exhaust pipe 5 decreases to a set value, the controller 9 opens the control valve 11, and the gas used to back-blow the filter 402 flows out from the gas source 10 and blows toward the filter assembly 4 through the back-blow pipe and the nozzle 12, thereby cleaning the filter 402. After the filter 402 is unblocked, the air in the feeding bin 2 is sucked into the exhaust pipe 5. At this time, the pressure in the exhaust pipe 5 gradually increases. After the pressure increases to another set value, the controller 9 closes the control valve 11.

[0033] When the filter 402 is damaged, the mounting ring 401 is pulled downward. After the mounting ring 401 is stressed, the engaging protrusion 301 and the engaging groove 40331 slide relative to each other, so that the engaging arm 4033 gradually opens, so that the entire filter 402 is removed from the suction pipe 3. Then, the magnet 406 used to fix the filter 402 is removed, and the locking nut 405 is loosened to move the movable pin 4042 to the side close to the center, so that the filter 402 is restored to a relaxed state, so that the filter 402 can be removed from the mounting ring 401.

[0034] When installing a new filter screen 402, firstly, the filter screen 402 is sleeved on the movable pin 4042 and the fixed pin 4041, and then, the movable pin 4042 is pulled to move so as to tighten the filter screen 402 between two adjacent fixed pins 4041. After the filter screen 402 is tightened, the locking nut 405 is screwed to fix the movable pin 4042.

[0035] The utility model can prevent powder from scattering by providing the suction pipe 3 and the exhaust fan 6, thereby improving the operating environment and avoiding affecting the health of the operator. By providing the filter assembly 4 at the bottom of the suction pipe 3, the loss of materials can be reduced and the pollution to the environment can be reduced.
