Meanwhile, the material is spirally cut into the rotating bin, so that friction is generated between the material and between the material and the shell, and impurities such as dust, harmful substances and the like on the surface of the material are stripped from the surface of the material, so that the cleanliness of the material is improved, and the cleaning effect is improved.

In this embodiment, the main portion of the feed channel extends downward, but in some embodiments, the feed channel may face in other directions, keeping the feed direction tangential.

The feeding and discharging channel 500 further comprises a feeding and discharging joint 503, the feeding and discharging joint 503 is detachably connected with the material window 205, and the feeding channel 501 and the discharging channel 502 are respectively connected with the feeding and discharging joint 503; the feeding and discharging connector is arranged, and the feeding and discharging connector realizes the function of detachably connecting the feeding and discharging channel to the material window so as to clean the feeding and discharging channel; in some embodiments, the feeding and discharging channel can be integrally formed with the shell, so that the cost is saved.

In order to enable the material to rotate tangentially in the feeding and discharging channel and to cut into the material window smoothly and spirally, the feeding and discharging joint 503 comprises an arc-shaped inner wall 506, an inner wall 507 at one side of the feeding channel 501 is tangent to the arc-shaped inner wall 506, and when the material reaches the feeding and discharging joint along the feeding channel, the material will rotate tangentially in time under the action of the arc-shaped inner wall to cut into the rotary bin spirally. The arc inner wall can be arc surface shape or other arc shape.

The feed channel 501 forms a feed inlet 504 at an inner arcuate wall 506 and the discharge channel 502 forms a discharge outlet 505 at the inner arcuate wall 506. In order to ensure that the material discharged from the material window can smoothly enter the discharge channel from the discharge port and be discharged along with the main body part of the discharge channel, the material is prevented from falling into the feed channel in the discharging process, and the height of the feed port 504 is higher than that of the discharge port 505. The discharged material will not reach the feed opening, thereby avoiding that the discharged material falls into the feed channel.

In this embodiment, because the main part of feedstock channel extends the setting to the downside, consequently still need set up air exhaust device, from the above-mentioned content to rotatory storehouse, the casing has made detailed description, it can be seen that the supply and the emission of the material of this embodiment are all gone on through a window, on this basis, if air exhaust device during inoperative or when not setting up air exhaust device, the casing is inside can not form the negative pressure, can not produce the air current in material mouth or material window, at this moment, when needs material loading, rotatory storehouse should keep first direction of rotation, and when needs the unloading, rotatory storehouse should switch to the second direction of rotation, just can discharge the material in the rotatory storehouse.

The feeding and discharging mode enables the feeding and discharging to be carried out only through gravity, so that materials in the storage bin lower than the material window or the material port cannot be conveyed into the rotary bin; in order to solve the problem and improve the feeding efficiency, the air extractor is arranged at the sewage discharge port of the shell, so that the gravity can be overcome to convey materials;

specifically, the method comprises the following steps:

in this embodiment, as shown in fig. 2, under the action of the air exhaust device 400, the material inlet/outlet channel 500 will be in a negative pressure state, and the material inlet/outlet device sucks the material into the high-efficiency material conveying 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 high-efficiency material conveying device can discharge materials outwards in the non-negative pressure state.

More specifically, as shown in fig. 3, the feeding and discharging channel includes a feeding channel 501 and a discharging channel 502, a main portion of the feeding channel extends downward, a main portion of the discharging channel extends downward, the material under negative pressure is fed into the material window 205 through the feeding channel 501 by means of negative pressure, and the material discharged from the material window 205 under non-negative pressure is discharged along the discharging channel 502 by means of gravity.

The main part of charge-in passage extends to the downside and sets up, the material relies on the negative pressure to follow charge-in passage past the material window feeding, the main part of charge-in passage that can make like this also can not produce the not thorough problem of material transport, because, extend the setting to the downside with the main part, make the material need overcome the effect of gravity and just can reach the material window, when negative pressure state relieved, the material of retention in the charge-in passage main part will fall back to storage component under the effect of gravity, therefore can not form in charge-in passage main part and remain, make charge-in passage's main part can keep clean health, thereby good transport effect and conveying efficiency have been guaranteed.

In addition, discharging channel's ejection of compact direction is the tangential direction of material window (like the arrow point that fig. 3 discharging channel shows), consequently under air exhaust device's work, outside air can get into along discharging channel under the negative pressure to be tangential direction and inhale the material window, the air current that tangential direction cut into will form the heliciform vortex, the material that gets into from the feedstock channel tangential, under the effect of heliciform vortex, will be more difficult for stopping between material window and material mouth, and get into in the rotatory storehouse more easily, the conveying efficiency of material has been improved. Meanwhile, the formed spiral vortex can impact the material, further increase friction and improve the cleaning effect.

As shown in fig. 3, in order to prevent the material cut from the feeding channel from falling into the discharging channel when passing through the discharging channel, the discharging channel and the feeding channel are tangent to the arc-shaped inner wall along the same rotation direction, and when the material passes through the discharging hole in the arc-shaped inner wall, the rotation direction of the material deviates from the discharging direction of the discharging channel, so that the material which keeps rotating in the feeding and discharging joint can be prevented from falling into the discharging channel.

The feeding and discharging channel of this embodiment can overcome gravity to feed materials into the high-efficiency material conveying device, and meanwhile, in cooperation with the feature that the rotary 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 that, as shown in fig. 3, 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 materials are added by using negative pressure, and the feeding channel 501 does not need to be arranged upwards to enable the materials to enter the rotary bin by using gravity, the feeding channel 501 and the discharging channel 502 can be communicated with each other, no partition plate is needed to be arranged between the feeding channel 501 and the discharging channel 502, and when feeding, 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.

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 shell and the rotating bin have pressure difference with the outside, and therefore outside air is continuously poured into the shell 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. 2, the air extracting device includes an air pump 401, a filter 403, and a dust box 402. The air pump 401 is fitted into the filter mesh 403, and both are fixed in the dust box 402.
