[0022] When the application is used, first, superfine material enters high-speed pulverizer for crushing and preliminary mixing;The material after crushing enters air flow grading system through the injection channel 7 at the top, i.e. directly delivered to the centrifugal component 10 at the top, and separated into two different particle size grades of powder by power component 5;Each particle size grade of powder enters the inside of quantitative channel 15, and quantitative channel 15 passes through transmission mechanism 14, according to the preset ratio requirement, control the size of groove 32 on plugging column 31 and the transmission ratio of transmission mechanism 14, and then realize accurate proportioning of each powder;The proportioned powder enters the bottom stirring tank 1 and is fully mixed and uniform, and finally the product meeting the requirements is obtained.

The surface of the top butt joint sleeve 12 is welded with the driven gear 20, the driving gear 19 and the driven gear 20 are engaged, the top butt joint sleeve 12 is inserted with the injection channel 7 above, the injection channel 7 is used for conveying the crushed raw materials of photovoltaic glass powder to the inside of the centrifugal assembly 10, the inner wall top end of the centrifugal bin 11 is provided with a diffusion pipeline 13, and the middle of the diffusion pipeline 13 is connected with the inside of the top butt joint sleeve 12. The raw materials are directly conveyed to the middle area of the centrifugal assembly 10 and subjected to the bidirectional influence of centrifugal force and air flow extraction at the middle position, so that the separation purpose can be achieved immediately after being put into the inside, the efficiency of classification is improved, and the automatic quantitative feeding and uniform mixing effect of large particle powder can also be automatically realized by cooperating with the transmission mechanism 14 at the bottom.

[0024] Specifically, after the motor 17 at the top is started, the driving shaft 18 is driven to rotate by the motor 17, the driving shaft 18 drives the driving gear 19 and the driven gear 20 at the tail end to rotate, the driven gear 20 drives the top butt joint sleeve 12 to rotate, that is, the whole centrifugal bin 11 is controlled to rotate, so that the crushed materials put into the inside can diffuse towards the two ends under the centrifugal force, and the air blower 35 at the bottom is started to blow the air flow from the inside towards the bottom. In this process, the centrifugal force on the large / heavy particles is much larger than the air flow suction force. They are mainly disturbed by the centrifugal force and are thrown to the periphery of the centrifugal bin 11 and fall or slide along the inner wall at the tail end. Finally, they pass through the centrifugal bin 11 from the outside into the inside of the classification tank 6; small / light particles: the air flow suction force on them is greater than the centrifugal force. They are mainly affected by the suction force and are sucked into the bottom butt joint sleeve 34 and finally conveyed towards the stirring tank 1 at the bottom through the transmission mechanism 14.

[0025] The grading tank 6 comprises a supporting plate 23, a fitting plate 24 and grading bins 26.

The centrifugal assembly 10 is pressed on the supporting plate 23 through the bottom ball 22, and the end of the centrifugal bin 11 is used to press on the surface of the fitting plate 24. The top and middle region of the bottom of the grading tank 6 are in an open state. The grading tank 6 is fixed as a whole with the lower stirring tank 1 through the quantitative channel 15. The grading bins 26 are arranged on both sides of the grading tank 6 in a symmetrical manner. The gap is arranged between the top of the two ends of the centrifugal bin 11 and the inner wall top end of the grading tank 6. The grading tank 6 is arranged on the top. The centrifugal assembly 10 is directly driven to rotate by the power assembly 5. The air flow grading process of the feeding raw material can be realized by cooperating with the bottom air blower 35. During the rotation process, the large and small size particles after grading are automatically transported towards the bottom, so as to realize the continuous and uninterrupted feeding and discharging and uniform stirring process, and the material preparation process is simplified.

[0026] Specifically, during the high-speed rotation of the centrifugal bin 11, the movable butt joint hole 21 at the end of the bottom is rotated along the surface of the fitting plate 24 until the movable butt joint hole 21 is aligned with the fixed butt joint hole 25, so that the large particle powder in the centrifugal bin 11 enters the inside of the grading bin 26 through the two holes in sequence, and finally enters the inside of the quantitative channel 15 from the bottom of the grading bin 26 for subsequent quantitative process. The intermediate small particle powder is affected by the air flow at the moment when it is sprayed from the diffusion pipe 13 towards the bottom, so that it can be directly sucked towards the middle region, so as to achieve the grading purpose.

[0027] The transmission mechanism 14 comprises a driven shaft 27, a blocking column 31, a first bevel gear 36 and a second bevel gear 29, the surface of the bottom butt joint sleeve 34 is keyed with the first bevel gear 36, the top end of the stirring tank 1 is screwed with a supporting sleeve 28, the inside of the supporting sleeve 28 is inserted with the driven shaft 27, one end of the driven shaft 27 is connected with the blocking column 31, the end of the blocking column 31 is attached with a matching pad 30. The surface of the blocking column 31 is provided with a groove 32, and the number of the groove 32 on each blocking column 31 is two, the side of the blocking column 31 and the surface of the matching pad 30 are matched with the inner wall of the quantitative channel 15, the other end of the driven shaft 27 is provided with the second bevel gear 29. The first bevel gear 36 and the second bevel gear 29 are engaged, the inside top end of the stirring tank 1 is installed with a conveying pipeline 37, the top end of the conveying pipeline 37 is installed with a blower 35, the top end of the blower 35 is aligned with the end of the bottom butt joint sleeve 34, and the side of the first bevel gear 36 is engaged with the two second bevel gears 29 at the same time. Through the single power assembly 5 at the top, the effects of centrifugal classification and quantitative conveying can be directly realized, the efficiency of mixing processing is improved, the degree of automation is high, and the equipment cost and occupied space are reduced.

[0028] Specifically, when the power assembly 5 at the top is started to drive the whole centrifugal assembly 10 to operate, the first bevel gear 36 is also driven to rotate through the bottom butt joint sleeve 34, the two second bevel gears 29 on the sides are driven to rotate by the first bevel gear 36, and the end blocking column 31 is driven to rotate through the rotation of the driven shaft 27. Since the blocking column 31 is inserted into the inside of the quantitative channel 15 through the guide sleeve 33, when one of the grooves 32 on the surface is rotated vertically upward during the rotation of the blocking column 31, the larger particle powder can fall into the inside of the groove 32. With the continuous rotation of the driven shaft 27, the groove 32 is rotated vertically downward, at this time, the powder in the groove 32 after quantitative can be put into the inside of the stirring tank 1 at the bottom, and the purpose of quantitative conveying is achieved. The bottom butt joint sleeve 34 is also directly aligned with the blower 35 at the bottom, so that the small particles in the centrifugal bin 11 can be directly extracted through the blower 35 and conveyed into the conveying pipeline 37 below, and then diffused into the inside of the stirring tank 1 through the diffusion port 16 at the bottom end of the conveying pipeline 37. The top end of the stirring shaft 8 is supported below the diffusion port 16 through the bearing, for providing stable support.
