[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1-5As shown, this embodiment proposes a dust recovery device for a flour production workshop, including an inlet and outlet cleaning component 1 and an expansion reversing mechanism 3.

The bolt inner beam 301 is bolted to the upper inner side of the inlet and outlet air cleaning assembly 1. The sleeve pipe 302 is provided on the inner side of the bolt inner beam 301, and the lifting frame 303 is provided below the sleeve pipe 302. The nozzle 304 is provided on the outer side of the lifting frame 303, and the air distribution pipe 305 is provided above the nozzle 304. The through connecting pipe 306 is provided above the sleeve pipe 302, and the air pump 307 is provided at one end of the through connecting pipe 306. The filter screen 308 is provided at the input end of the air pump 307.

[0023] The nozzle 304 and the air distribution pipe 305 are distributed at equal angles around the central axis of the hoisting frame 303.

[0024] In this embodiment, when the adhesion and interception are carried out for a long time, the intake valve block 107 and the exhaust valve block 1010 are closed. After closing, the air pump 307 outputs power to drive the output end to run, so that the filter screen 308 inputs sufficient air into the through pipe 306 and finally outputs it through the nozzle 304 on the hoisting frame 303 and then expands through the non-woven bag 205.

[0025] The air intake and exhaust cleaning assembly 1 includes a pad 101, a square frame 102, a dust collection chamber 103, a sound insulation panel 104, a bolt top plate 105, a bottom hopper 1012, a sleeve box 1013, and a cleaning box 1014. The dust collection chamber 103, which houses the sound insulation panel 104, is bolted to the top of the pad 101 via the square frame 102. The top of the dust collection chamber 103 is equipped with a bolt top plate 105.

The cleaning box 1014 is located inside the sleeve box 1013.

[0026] In this embodiment, after the dust falls, it is struck by the rotating bar 406 and the rubber strip head 407 in the dust collection chamber 103, causing the dust to be input through the bottom hopper 1012 into the cleaning box 1014 inside the casing 1013 for storage, so as to facilitate collection and cleaning.

[0027] The air intake and exhaust cleaning assembly 1 also includes an air intake 106, an air intake valve block 107, an air intake fan 108, an exhaust port 109, an exhaust valve block 1010, and an exhaust fan 1011. An air intake 106 with an air intake valve block 107 is provided on the lower side of the dust collection chamber 103, and an air intake fan 108 with bolts is provided on the outer side of the air intake 106. An exhaust port 109 with an exhaust valve block 1010 is provided on the upper side of the dust collection chamber 103, and an exhaust fan 1011 with bolts is provided on the outer side of the exhaust port 109.

[0028] In this embodiment, during use, by opening the intake valve block 107 and the exhaust valve block 1010, the intake port 106 and the exhaust port 109 are opened. After opening, the intake fan 108 and the exhaust fan 1011 are used to output power to drive the output end to run, so as to achieve the effect of opening the air extraction.

[0029] The interception and attachment assembly 2 includes a bolt inner plate 201, a circular plate 202, a sleeve 203, a binding wire 204, and a non-woven bag 205. The bolt inner plate 201 is bolted to the inner side of the middle of the dust collection chamber 103. The inner side of the bolt inner plate 201 is provided with a bolt-assembled circular plate 202. The inner side of the circular plate 202 is provided with a sleeve 203 for sleeve installation. The non-woven bag 205 is bound to the bottom of the sleeve 203 by the binding wire 204.

[0030] In this embodiment, when air is drawn out by the intake fan 108 and the exhaust fan 1011, the non-woven bag 205, which is bound to the binding wire 204 below the sleeve 203, assists in blocking a large amount of dust.

[0031] The striking mechanism 4 includes a cylinder base 401, a hydraulic cylinder 402, a push rod 403, a lifting base 404, a drive motor 405, a rotating bar 406, and a rubber strip head 407. The cylinder base 401 is sleeved and connected to the inner sides of both ends of the bolt inner beam 301. The hydraulic cylinder 402 is arranged above the cylinder base 401. The output end of the hydraulic cylinder 402 is provided with a push rod 403, and the lifting base 404 is arranged below the push rod 403. The inner side of the lifting base 404 is provided with a drive motor 405, and the output end of the drive motor 405 is provided with a rotating bar 406. The outer side of the rotating bar 406 is provided with a rubber strip head 407.

[0032] In this embodiment, when the non-woven bag 205 expands, the hydraulic cylinder 402 on the cylinder base 401 outputs power to drive the output end to run, causing the push rod 403 to move up and down. During the lifting operation, the drive motor 405 on the lifting base 404 outputs power to drive the output end to run, so that the rotating bar 406 and the rubber strip head 407 rotate at high speed and strike the non-woven bag 205, causing the dust to fall.

[0033] The working principle of the dust recovery device in the flour production workshop is as follows: During operation, the inlet valve block 107 and the exhaust valve block 1010 are opened, causing the inlet port 106 and the exhaust port 109 to open. After opening, the inlet fan 108 and the exhaust fan 1011 output power to drive the output end, achieving the effect of air extraction. When the air is extracted and discharged by the inlet fan 108 and the exhaust fan 1011, the non-woven bag 205, connected by the binding wire 204 below the sleeve 203, assists in intercepting a large amount of dust. After prolonged dust accumulation and interception, the inlet valve block 107 and the exhaust valve block 1010 close. After closing, the air pump 307 outputs power to drive the output end, causing the filter sieve 308 to input sufficient air into the through-pipe 3. 06 Finally, after being output through the nozzle 304 on the hoisting frame 303, it expands through the non-woven bag 205. After the non-woven bag 205 expands, the hydraulic cylinder 402 on the cylinder base 401 outputs power to drive the output end, causing the push rod 403 to move up and down. During the lifting operation, the drive motor 405 on the lifting base 404 outputs power to drive the output end, so that the rotating bar 406 and the rubber strip head 407 rotate at high speed and strike the non-woven bag 205. After the strike, the dust falls. After the dust falls, it is struck by the rotating bar 406 and the rubber strip head 407 in the dust collection chamber 103, so that the dust is input through the bottom hopper 1012 into the cleaning box 1014 inside the casing 1013 for storage, so as to facilitate collection and cleaning.
