At this time, the fan blade may not be provided, and the fan blade may be provided.

When the materials are filled in the rotary bin, air flow is formed under the suction of the air extractor, so that waste materials and dust generated by the friction of the materials in cleaning can be separated in an accelerating manner, and the waste materials and the dust are discharged from the sewage outlet to promote the cleaning effect.

In this embodiment, as shown in fig. 12, a material inlet and outlet channel 500 is further disposed at the material window 205 and used for feeding and discharging the material cleaning device, the material inlet and outlet channel 500 is disposed on the material window 205, and under the action of the air extractor 400, the material inlet and outlet channel 500 is also in a negative pressure state, and at this time, the material inlet and outlet device sucks the material into the material cleaning device through the generated negative pressure. When the air exhaust device stops working, the feeding and discharging device is in a non-negative pressure state, and the material cleaning device can discharge materials outwards in the non-negative pressure state.

More specifically, as shown in fig. 13, the feeding and discharging channel includes a feeding channel 501 and a discharging channel 502, the material discharged from the material window 205 under non-negative pressure is discharged along the discharging channel 502 by gravity, and the material under negative pressure is fed along the feeding channel 501 to the material window 205 by negative pressure.

The feeding and discharging channel of this embodiment can overcome gravity to feed materials into the material cleaning device, and meanwhile, in cooperation with the feature that the rotating bin described in embodiment 1 can feed and discharge materials through the same material port, the possibility that the feeding channel and the discharging channel are integrally arranged is realized, and when the material port discharges materials, the materials fall under the action of gravity, so, as shown in fig. 11, the discharging channel 502 should be arranged downwards or obliquely downwards, the discharging channel arranged downwards or obliquely downwards can be connected with the feeding channel, the feeding channel 501 can be arranged in any direction because the material is added by using negative pressure, and it is not necessary to arrange the feeding channel 501 upwards to make the materials enter the rotating bin by using gravity, the feeding channel 501 and the discharging channel 502 can be communicated with each other, no partition plate is required to be arranged between the feeding channel 501 and the discharging channel 502, and during feeding, because the feeding channel 501 and the discharging channel 502 are inevitably communicated with the material window 205, therefore, when air exhaust device during operation, all be in negative pressure state in discharging channel 501 and the feedstock channel 502, external air will flow along discharging channel and feedstock channel, and the inhaled material from feedstock channel can not fall into discharging channel when discharging channel this moment, because discharging channel has the air current by outside material window, has prevented the whereabouts of material, so the material can only enter into in the material window.

When air exhaust device was out of work, in going into the inlet and outlet passageway from material window exhaust material, in order to prevent that the material from entering into inlet and outlet passageway, consequently, inlet and outlet passageway's height will be higher than discharging channel for inlet and outlet passageway and discharging channel form a step in the direction of height, fall into inlet and outlet passageway back, because be in non-negative pressure state among the discharging channel, do not have pressure differential with the external world, the material will slide out along discharging channel under the effect of gravity.

According to the embodiment, the turning vanes can control the material to be discharged from the material port when the rotary bin rotates in the second rotation direction, and can control the material to be far away from the material port and to be continuously turned in the cleaning cavity when the rotary bin rotates in the first rotation direction. Because the air extractor is arranged, when the air extractor works, the dust storage bin and the rotating bin have pressure difference with the outside, and therefore outside air is continuously poured into the dust storage bin and the rotating bin from the material port, even if the rotating bin rotates in the second rotating direction, the poured air flow can prevent materials from being discharged from the material port and the material window.

The rotary bin in the embodiment can discharge materials only by switching the rotating direction, when the rotary bin rotates at a high speed, the moving inertia under reverse rotation needs to be overcome, the moving inertia is overcome, the time is consumed in a high-speed state, and meanwhile, the motor is also adversely affected.

More specifically, as shown in fig. 12, the air-extracting device includes an air pump 401, a filter 403, and a housing 402. The air pump 401 is fitted into the filter mesh 403, and both are fixed in the housing 402.
