Referring to fig. 1 and 2, the dust-removing winnowing machine according to the embodiment of the utility model comprises a separating chamber 110, a diffusion chamber 120, a discharge conveying device 220, a plurality of first suction boxes 310, second suction boxes 320 and a fan 500, wherein the diffusion chamber 120 is communicated with the separating chamber 110, and a discharge port 121 is arranged at one end of the diffusion chamber 120 far away from the separating chamber 110; the discharging and conveying device 220 is arranged in the diffusion chamber 120, and one end of the discharging and conveying device 220 is arranged through the discharging hole 121; the first suction box 310 is arranged at the top of the diffusion chamber 120, and the suction port of the first suction box 310 is communicated with the inside of the diffusion chamber 120; the second suction box 320 is located outside the diffusion chamber 120 and is disposed at the discharge port 121, and the suction port of the second suction box 320 is opposite to the discharge conveying device 220; the air inlets of the blower 500 are communicated with all the first air suction boxes 310 and the second air suction boxes 320, and the air outlets of the blower 500 are communicated with the air inlets of the separation chamber 110, wherein a first dust removing device 600 is arranged between the air outlets of the blower 500 and the separation chamber 110, and/or a second dust removing device 700 is arranged between the air inlets of the blower 500 and the first air suction boxes 310.

According to the winnowing machine provided by the utility model, the second suction box 320 communicated with the suction port of the fan 500 is arranged at the discharge port 121 of the diffusion chamber 120, so that in the working process, the winnowing machine can utilize the second suction box 320 to absorb dust discharged from the discharge port 121, and then the recovered dust is removed through the first dust removing device 600 or the second dust removing device 700 arranged on the winnowing machine.

Referring to fig. 1 and 2, the flow direction of the air flow in the air separator is shown by arrows in fig. 1 and 2, wherein most of the air flow in the diffusion chamber 120 is recovered by the first suction box 310, a small part of the air flow can be discharged from the discharge port 121 of the diffusion chamber 120, the discharge of the light component 920 caused by the reverse flow of the air flow at the discharge port 121 of the diffusion chamber 120 is avoided, the second suction box 320 can recover the air flow discharged from the discharge port 121, and the second suction box 320 can also absorb the new air in the external environment. Therefore, most of the air intake required by the blower 500 is provided by the air flow in the first suction box 310 recovered diffusion chamber 120, and the other part of the air intake can be complemented by the air flow sucked by the second suction box 320, so that the air intake of the blower 500 is sufficient by the air supplementing effect of the second suction box 320, and the normal operation of the winnowing machine is ensured.

In addition, the second suction box 320 is located outside the diffusion chamber 120, which is convenient for installation and maintenance. In a specific implementation process, when the first suction box 310 fails to work normally due to a problem, if the air separator is needed to finish the sorting work of the mixed materials, the second suction box 320 can be used for emergency temporarily, and the air separator can work without stopping.

In a specific implementation process, the air separator may be provided with the first dust removing device 600 and the second dust removing device 700 at the same time, or may be provided with only the first dust removing device 600 or the second dust removing device 700.

Referring to fig. 1 and 2, in the embodiment, the air separator further includes a feeding conveyor 210, the feeding conveyor 210 is located at one side of the separation chamber 110, the feeding conveyor 210 is used for feeding the mixed material into the separation chamber 110, the separation drum 130 is disposed in the separation chamber 110, during the operation of the air separator, the air flow provided by the fan 500 is blown obliquely upwards between the separation drum 130 and the feeding conveyor 210, so that the heavy component 910 in the mixed material falls before the separation drum 130, and the light component 920 is conveyed from above the separation drum 130 to the diffusion chamber 120 along with the air flow.

Referring to fig. 1 and 2, it is conceivable that in some embodiments, the air outlet of the blower 500 is connected with a diverter valve 800, a first port of the diverter valve 800 is connected with the separation chamber 110, and a second port of the diverter valve 800 is connected with the first dust removing device 600. In the working process of the winnowing machine, a part of air flow sent by the fan 500 is discharged into the external environment after being dedusted by the first dedusting device 600, so that the concentration of dust in the winnowing machine can be continuously reduced, and the normal working of the winnowing machine is ensured; another portion of the air flow from the fan 500 may enter the separation chamber 110 without blocking to ensure that the wind force is sufficient for the sorting operation. In addition, during the operation of the air separator, the second suction box 320 can suck in new air from the external environment, and the first dust removing device 600 discharges a part of old air flow, so that the air separator can continuously supplement the new air flow and discharge the old air flow, thereby ensuring the freshness of the air flow in the circulation.

In an implementation, the first dust extraction device 600 may be a filter with replaceable cartridges, a water-washed filtration device, or other filters.

It should be noted that, in the implementation process, the first dust removing device 600 may be connected in series between the fan 500 and the separation chamber 110, that is, the air outlet of the fan 500, the first dust removing device 600, and the separation chamber 110 are sequentially connected.

Referring to fig. 2, it is conceivable that in some embodiments, the second dust removing device 700 includes a cyclone 710, an air inlet of the cyclone 710 communicates with the first suction box 310, and an air outlet of the cyclone 710 communicates with an air inlet of the blower 500. Thus, by providing the cyclone 710 between the suction port of the blower 500 and the first suction box 310, most of the dust, plastic film, and other impurities harmful to the operation of the blower 500 can be removed before the air flow enters the blower 500, thereby reducing the maintenance frequency of the apparatus, stabilizing the smooth operation of the apparatus, and prolonging the service life of the apparatus.

Referring to fig. 2, a hopper 720 is provided at a lower end of the cyclone 710, and after a certain amount of dust is collected in the hopper 720, the hopper 720 may be opened to discharge the dust.

It should be noted that, in the implementation process, the second dust-removing device 700 may also be configured in other manners, for example, the second dust-removing device 700 may be configured as a filter with a replaceable filter element.

Referring to fig. 1 and 2, it is conceivable that in some embodiments, the air suction port of the blower 500 is connected to the air return duct 400, the air return duct 400 is connected to all the first suction boxes 310, and one end of the air return duct 400 away from the blower 500 is connected to the second suction box 320, so that when both the first suction box 310 and the second suction box 320 work normally, the first suction box 310 sucks air flow earlier than the second suction box 320, and the negative pressure at the second suction box 320 is smaller, so that the suction force generated by the second suction box 320 is smaller, and the second suction box 320 can suck dust discharged from the discharge port 121, and meanwhile, the light component 920 conveyed by the discharge device is prevented from being sucked by the second suction box 320.

Referring to fig. 1 and fig. 2, it is conceivable that, in a specific implementation process, the first suction box 310 and the second suction box 320 may be configured with air pressure adjusting valves, and negative pressure distribution between the first suction box 310 and the second suction box 320 is achieved through a plurality of air pressure adjusting valves, so that the problem that the light component 920 is sucked due to excessive suction force of the second suction box 320 caused by excessive negative pressure of the second suction box 320 or dust discharged from the discharge port 121 cannot be effectively recovered due to excessive negative pressure of the second suction box 320 is avoided.

Referring to fig. 1 and 2, it is envisioned that in some embodiments, the diffusion chamber 120 and the outfeed conveyor 220 are both disposed at an incline, wherein the end of the diffusion chamber 120 near the separation chamber 110 is lower than the end of the diffusion chamber 120 remote from the separation chamber 110. Therefore, in the process that the light component 920 is thrown into the discharging and conveying device 220 in the diffusion chamber 120 in a curved track, because the discharging and conveying device 220 and the diffusion chamber 120 are obliquely arranged, the horizontal displacement of the light component 920 is smaller, so that the light component 920 can be thrown onto the discharging and conveying device 220 more quickly, and meanwhile, the lengths of the discharging and conveying device 220 and the diffusion chamber 120 can be shorter, so that the cost is reduced.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The present embodiment has been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiment, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit.
