[0028] In some embodiments, the stirring mechanism includes a first driving member and a second driving member.

The feed inlet 400 is used to introduce materials of various particle sizes into the stirring tank 100, the discharge outlet is used to discharge the uniformly stirred and mixed materials, and the liquid inlet pipe 500 is used to introduce liquid into the stirring tank 100.

[0030] In some embodiments, when the stirring mechanism is in the second working state, by setting the rotation directions of the first stirring motor 210 driving the first stirring blade 260 and the second stirring motor 310 driving the second stirring blade 350 to be the same, and setting the rotation speed of the first stirring motor 210 to be greater than that of the second stirring motor 310, the first stirring blade 260 is made to scrape off the attachments adhering to the upper surface of the second stirring blade 350, and the second stirring blade 350 is made to scrape off the attachments adhering to the lower surface of the first stirring blade 260; after moving for a period of time, while keeping the rotation directions of the first stirring motor 210 driving the first stirring blade 260 and the second stirring motor 310 driving the second stirring blade 350 the same, the rotation speed of the first stirring motor 210 is set to be less than that of the second stirring motor 310, so that the first stirring blade 260 scrapes off the attachments adhering to the lower surface of the second stirring blade 350, and the second stirring blade 350 scrapes off the attachments adhering to the upper surface of the first stirring blade 260.

[0031] In some embodiments, when the stirring mechanism is in the second working state, by setting the rotation directions of the first stirring motor 210 driving the first stirring blade 260 and the second stirring motor 310 driving the second stirring blade 350 to be opposite, the first stirring blade 260 is made to scrape off the attachments adhering to the upper surface of the second stirring blade 350, and the second stirring blade 350 is made to scrape off the attachments adhering to the lower surface of the first stirring blade 260; after operating for a period of time, the rotation directions of the first stirring motor 210 driving the first stirring blade 260 and the second stirring motor 310 driving the second stirring blade 350 are made to be opposite again, so that the first stirring blade 260 scrapes off the attachments adhering to the lower surface of the second stirring blade 350, and the second stirring blade 350 scrapes off the attachments adhering to the upper surface of the first stirring blade 260.

[0034] The second stirring assembly 300 includes a second stirring motor 310, a sliding sleeve 320, a second rotating shaft 330, a second compression spring 340, second stirring blades 350, a third scraping plate 360, a fourth scraping plate 361, a second roller 370 and a second hinge block 380. The second stirring motor 310 is fixedly connected to the connecting seat 110 by bolts. One end of the second rotating shaft 330 is fixedly connected to the second stirring motor 310. The sliding sleeve 320 is sleeved on the second rotating shaft 330 in a slidable manner along the axial direction of the second rotating shaft 330, and the sliding sleeve 320 rotates synchronously with the second rotating shaft 330. The second compression spring 340 is sleeved on the second rotating shaft 330. One end of the second compression spring 340 abuts against the second rotating shaft 330, and the other end abuts against the sliding sleeve 320.

[0035] The first scraping plate 270 and the third scraping plate 360 face in the same direction, and the second scraping plate 271 and the fourth scraping plate 361 face in the same direction.

[0036] Before stirring, materials of various particle sizes are introduced into the stirring tank 100 through the feeding port 400, and liquid (if any) is introduced into the stirring tank 100 through the liquid inlet pipe 500.

[0037] Under the action of the first compression spring 230 and the second compression spring 340, the first stirring blade 260 and the second stirring blade 350 are in an overlapping state.

[0038] During the stirring stage, the first stirring motor 210 and the second stirring motor 310 are started. The first stirring motor 210 and the second stirring motor 310 have the same rotation speed: the first stirring motor 210 drives the first rotating shaft 211 to rotate clockwise, and the second stirring motor 310 drives the second rotating shaft 330 to rotate clockwise; or the first stirring motor 210 drives the first rotating shaft 211 to rotate counterclockwise, and the second stirring motor 310 drives the second rotating shaft 330 to rotate counterclockwise (since at the beginning of stirring, the materials and water in the stirring tank 100 are in a separated state and the stirring resistance is large). Through the same-direction rotation of the first stirring motor 210 and the second stirring motor 310, the first stirring blade 260 and the second stirring blade 350 stir the materials and water in the stirring tank 100 in the same direction, effectively preventing the first stirring motor 210 and the second stirring motor 310 from burning out while improving the stirring efficiency.

[0039] After stirring for a period of time, the multi-grain-size mixture in the stirring tank 100 is gradually mixed, and the mixed materials are more likely to adhere to the stirring blades and the inner wall of the stirring tank 100. After the first stirring motor 210 and the second stirring motor 310 are set to stir in the same direction for a period of time through electronic control, the first stirring motor 210 and the second stirring motor 310 are made to rotate in opposite directions.

[0040] Suppose the first stirring blade 260 rotates counterclockwise and the second stirring blade 350 rotates clockwise (at this time, the first scraping plate 270 abuts against the second stirring blade 350). The reverse rotation of the first stirring blade 260 and the second stirring blade 350 causes the first stirring blade 260 to rise along the second stirring blade 350, and then the second scraping plate 271 scrapes off the particulate matter adhering to the second stirring blade 350, and the third scraping plate 360 scrapes off the particulate matter adhering to the first stirring blade 260. When the first stirring blade 260 passes over the second stirring blade 350, under the action of the first compression spring 230, the first stirring blade 260 and the second stirring blade 350 are again at the same height. When the first stirring blade 260 and the second stirring blade 350 meet again, the reverse rotation of the first stirring blade 260 and the second stirring blade 350 causes the first stirring blade 260 to rise along the second stirring blade 350, and then the second scraping plate 271 scrapes off the particulate matter adhering to the second stirring blade 350, and the third scraping plate 360 scrapes off the particulate matter adhering to the first stirring blade 260.

[0041] After stirring for a period of time, the attachments on the downward side fan blade surface of the first stirring blade 260 are scraped clean, and the attachments on the upward side fan blade surface of the second stirring blade 350 are scraped clean. At this time, the first stirring blade 260 is rotated clockwise and the second stirring blade 350 is rotated counterclockwise through electric control. The reverse rotation of the first stirring blade 260 and the second stirring blade 350 causes the second stirring blade 350 to rise along the first stirring blade 260. Then, the particulate matter attached to the second stirring blade 350 is scraped off by the first scraper 270, and the particulate matter attached to the first stirring blade 260 is scraped off by the fourth scraper 361. When the second stirring blade 350 passes over the first stirring blade 260, under the action of the second compression spring 340, the first stirring blade 260 and the second stirring blade 350 are again at the same height. When the first stirring blade 260 and the second stirring blade 350 meet again, the reverse rotation of the first stirring blade 260 and the second stirring blade 350 causes the second stirring blade 350 to rise along the first stirring blade 260. Then, the particulate matter attached to the second stirring blade 350 is scraped off by the first scraper 270, and the particulate matter attached to the first stirring blade 260 is scraped off by the fourth scraper 361. After stirring for a period of time, the attachments on the upward side fan blade surface of the first stirring blade 260 are scraped clean, and the attachments on the downward side fan blade surface of the second stirring blade 350 are scraped clean.

[0042] By electrically controlling the first stirring motor 210 and the second stirring motor 310 to rotate in opposite directions, on the one hand, the particulate matter adhered to the first stirring blade 260 and the second stirring blade 350 can be cleaned in time, and the particulate matter adhered to the inner wall surface of the stirring tank 100 can be cleaned in time. Thus, both the service life of the blades and the motor can be extended, and the energy consumption of driving the stirring mechanism can be reduced. On the other hand, the continuous switching of the first stirring blade 260 and the second stirring blade 350 not only stirs the materials in the stirring tank 100 in the circumferential direction, but also stirs the materials in the stirring tank 100 in the axial direction. Furthermore, the materials in the stirring tank 100 are stirred in all directions, making the materials in the stirring tank 100 mixed evenly.

[0043] By electrically controlling the first stirring motor 210 and the second stirring motor 310 to have the same rotation direction while changing the relative rotational speed between the first stirring motor 210 and the second stirring motor 310, the cleaning process is the same as the cleaning process when the first stirring motor 210 and the second stirring motor 310 are set to have opposite rotation directions; on the one hand, the particulate matter adhering to the first stirring blade 260 and the second stirring blade 350 can be cleaned in time, and the particulate matter adhering to the inner wall surface of the stirring tank 100 can be cleaned in time, thereby improving the service life of the blades and the motor; on the other hand, the continuous switching of the first stirring blade 260 and the second stirring blade 350 enables the material in the stirring tank 100 to be stirred not only in the circumferential direction but also in the axial direction, and further stirs the material in the stirring tank 100 in all directions, making the material in the stirring tank 100 evenly mixed.

[0044] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0045] The above-described embodiments merely represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
