Referring to fig. 1-8, the present invention provides a dust-proof cleaning apparatus for a pulper, comprising a dust hood mechanism mounted directly above the pulper. In the working process of the pulper, when waste paper enters the pulper, a large amount of dust and paper scraps can be scattered through stirring of the pulper, and at the moment, the large amount of dust and paper scraps can be sucked away by a dust hood mechanism arranged above the pulper, so that the scattered large amount of dust and paper scraps can be prevented from escaping from a feeding port of the pulper, and the dust and paper scraps can be prevented from flying around to pollute the working environment.
Because the dust hood mechanism is arranged right above the pulper, when the pulper runs, because the liquid is arranged in the pulper, the pulper can volatilize more water mist in the high-speed running process, and the water mist and the flying dust can be bonded on the inner wall of the dust hood mechanism after being combined, so that the weight of the dust hood mechanism is increased, the dust collection efficiency is influenced, and the dust on the dust hood mechanism is required to be treated manually and regularly.
Therefore, the dust adhering to the inner wall of the dust hood mechanism can be cleaned in real time during the operation of the dust hood mechanism by the cooperation of the inner hood assembly 100, the outer hood assembly 200 and the cleaning assembly 300, so that the dust adhering to the inner wall of the dust hood mechanism is avoided, and the manual periodic treatment is not needed, so that the manual labor intensity is reduced.

As shown in fig. 8, when working, a worker can pump air into the air inlet channel 221 of the housing assembly 200, the air can drive the fan 320 at the input end of the gearbox 310 to rotate at a high speed when entering the air inlet channel 221, and then the input end of the gearbox 310 rotates, at this time, the gear set in the gearbox 310 can make the output end of the gearbox 310 rotate at a low speed, and the output end of the gearbox 310 is connected with the scraper assembly 330, and the scraper assembly 330 can do circular motion in the flaring section 111 and the throat section 112 to scrape dust adhered to the inner walls of the flaring section 111 and the throat section 112; the gearbox 310 is a prior art, and the internal structure and principles of the gearbox 310 are not described herein.
Meanwhile, when the air enters the pressure cavity 211 through the air inlet channel 221, the air pressure of the pressure cavity 211 is increased (the apertures of the first air outlet 251 and the second air outlet 261 are smaller), a part of the air in the pressure cavity 211 is uniformly provided with the first air outlet 251 along the circumferential direction and is ejected into the first air outlet channel 231 at a high speed, and according to the bernoulli principle, at this time, the air flow rate of the first air outlet channel 231 is increased, so that the air in the dust exhaust section 113 flows towards the first air outlet channel 231, and therefore, the outside air sequentially enters the first air outlet channel 231 through the flaring section 111, the throat section 112 and the dust exhaust section 113, so that the dust escaping from the material inlet of the pulper is absorbed.
The other part of the air in the pressure cavity 211 is uniformly provided with the second exhaust holes 261 in the circumferential direction and is ejected into the second exhaust channel 241 at a high speed, and the air entering the second exhaust channel 241 flows along the guiding section 241a of the second exhaust channel 241 and is discharged from the ejecting section 241b, so that the inner wall of the flared end of the flared section 111 forms an upward annular air flow, which can prevent dust from adhering to the flared section 111 on one hand and can blow the dust of the scraper assembly 330 into the dust exhaust pipe on the other hand, thereby enabling the dust to enter the first exhaust channel 231 along with the air flow.
It should be noted that, the first exhaust hole 251 is disposed along the circumferential direction and is close to the inner wall of the first exhaust channel 231, and the gas exhausted from the first exhaust hole 251 can avoid the dust entering the first exhaust channel 231 from settling and adhering to the inner wall of the first exhaust channel 231.
