DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figure 1 , an embodiment of the present invention provides a crystalline silicon material cleaning and recovery device, the crystalline silicon material cleaning and recovery device comprising:

[0024] A bottom plate 1 and a side plate 2, the side plate 2 is provided with a guide groove, and the end of the side plate 2 away from the bottom plate 1 is fixedly connected to the top plate 3; an entry and exit mechanism 4, which is installed on the top plate 3, and the power output end of the entry and exit mechanism 4 is fixedly connected to the trough body 5, and a stabilizing groove is provided on the inner wall of the trough body 5. The entry and exit mechanism 4 is used to drive the trough body 5 to rise or fall, and guide wheels 6 slidingly arranged in the guide groove are installed at both ends of the trough body 5; a conversion mechanism 7, which is installed in the trough body 5, and the power output end of the conversion mechanism 7 is fixedly connected to the clamping mechanism 8, and there are two clamping mechanisms 8. The conversion mechanism 7 is used to drive the two clamping mechanisms 8 to rotate, and the clamping mechanism 8 is used to clamp and fix the crystalline silicon material; a cleaning mechanism 9, which is installed on the bottom plate 1, and the entry and exit mechanism 4 is used to drive the crystalline silicon material fixed by the clamping mechanism 8 into the cleaning mechanism 9 for cleaning and recycling.

[0025] When using the crystalline silicon material cleaning and recovery device, first put the crystalline silicon material to be cleaned on the clamping mechanism 8 for fixing. After fixing, open the in-and-out mechanism 4, and the in-and-out mechanism 4 can drive the trough body 5 and the guide wheel 6 to move downward steadily along the guide groove. The trough body 5 moves downward and the clamping mechanism 8 can be driven downward by the conversion mechanism 7, so that the crystalline silicon material can be put into the cleaning mechanism 9 for cleaning. Open the cleaning mechanism 9, and the cleaning mechanism 9 can stir the cleaning agent. The cleaning mechanism 9 can also drive the clamping mechanism 8 to flip the crystalline silicon material, thereby speeding up the cleaning of the crystalline silicon. After the crystalline silicon material is cleaned, the in-and-out mechanism 4 is opened in reverse, so that the clamping mechanism 8 drives the crystalline silicon material to move out of the cleaning mechanism 9, and then the conversion mechanism 7 is opened. The conversion mechanism 7 drives the two clamping mechanisms 8 to rotate, and the other clamping mechanism 8 that fixes the crystalline silicon material is moved to the left side of the cleaning mechanism 9, and the crystalline silicon material that has been cleaned is moved to the right side of the cleaning mechanism 9. The in-and-out mechanism 4 is opened again, and the crystalline silicon material that needs to be cleaned is moved into the cleaning mechanism 9 for cleaning. The cleaned crystalline silicon material can be removed from the clamping mechanism 8 and placed on the right side of the cleaning mechanism 9 for recycling during this process.

[0026] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the entry and exit mechanism 4 includes: an electric telescopic rod 41, which is fixedly mounted on the top plate 3, and the trough body 5 and the power output end of the electric telescopic rod 41 are fixedly connected; a guide column 42, which is fixedly mounted on the top plate 3, and the guide column 42 is provided with a guide sleeve 43 fixedly connected to the trough body 5.

[0027] When cleaning the crystalline silicon material, the electric telescopic rod 41 is turned on, and the electric telescopic rod 41 drives the trough body 5 and the guide sleeve 43 to move downward along the guide column 42. The downward movement of the trough body 5 can enable the clamping mechanism 8 to bring the crystalline silicon material into the cleaning mechanism 9 for cleaning.

[0028] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the conversion mechanism 7 includes: a first power member 71, which is fixedly mounted on the inner wall of the trough body 5, the output shaft of the first power member 71 is fixedly connected to the first gear 72, and the first power member 71 is used to drive the first gear 72 to rotate; a central shaft 73, one end of which is rotatably connected to the middle of the trough body 5, and a second gear 74 engaged with the first gear 72 is fixed on the central shaft 73, and the other end of the central shaft 73 is fixedly connected to a turntable 75, and a stabilizing wheel 76 slidably arranged in a stabilizing groove is installed on the periphery of the turntable 75; a suspension rod 77, one end of which is fixedly connected to the turntable 75 and is provided with two, and the clamping mechanism 8 is fixedly connected to the other end of the suspension rod 77.

[0029] When the positions of the two clamping mechanisms 8 are switched, the first power member 71 is turned on. The first power member 71 is specifically a motor. The output shaft of the first power member 71 drives the first gear 72 to rotate, and the first gear 72 drives the second gear 74 and the center shaft 73 to rotate. The rotation of the center shaft 73 can drive the turntable 75 and the stabilizing wheel 76 to rotate stably in the stabilizing groove. The rotation of the turntable 75 can drive the two clamping mechanisms 8 to rotate through the suspension rod 77, and the two clamping mechanisms 8 can switch positions.

[0030] like Figure 2 and Figure 5 As shown, as a preferred embodiment of the present invention, the clamping mechanism 8 includes: a cover 81, which is fixedly connected to the conversion mechanism 7 and has a groove, a handle 82 is rotatably mounted on the cover 81, and the handle 82 is fixed with a first bevel gear 83 arranged in the groove; a fixed plate 84, which is fixedly mounted on the inner wall of the groove opened by the cover 81 and is provided with two, and a screw rod 85 is rotatably provided on the two fixed plates 84, and the two screw rods 85 have opposite thread rotation directions and are fixedly connected to the ends close to each other with a shaft rod 86, and the shaft rod 86 is fixed with a second bevel gear meshing with the first bevel gear 83 Wheel 87; a sliding rod 88, both ends of which are fixedly connected to the inner wall of the groove formed by the cover 81, and the two sliding rods 88 are provided with a pulling assembly 89 fixed to the inner wall of the top end of the groove, and the pulling assembly 89 is threadedly connected to the screw rod 85 and is provided with two; a support ring 810, which is fixedly connected to the pulling assembly 89, and a clamping block 811 is rotatably provided on the support ring 810, and a supporting plate 812 for placing crystalline silicon material is fixedly provided on the clamping block 811; a counterweight block 813, which is fixed on the clamping block 811, and a driven gear 814 is fixedly provided on one of the counterweight blocks 813.

[0031] When the crystalline silicon material is clamped and fixed, under the action of the counterweight block 813, the carrier plate 812 is always under the support ring 810. At this time, the crystalline silicon material can be placed on the two carrier plates 812, and the handle 82 is turned. The handle 82 drives the first bevel gear 83 to rotate. The rotation of the first bevel gear 83 can drive the second bevel gear 87, the shaft 86 and the screw 85 to rotate on the fixed plate 84. The rotation of the screw 85 can make the pulling assembly 89 drive the two support rings 810 to approach each other. When the two support rings 810 approach each other, the two clamping blocks 811 can be driven to approach each other. The two clamping blocks 811 can clamp the crystalline silicon material, thereby ensuring the stability of the crystalline silicon material during cleaning.

[0032] like Figure 2 and Figure 5As shown, as a preferred embodiment of the present invention, the pulling assembly 89 includes: a linkage column 891, which is fixedly mounted on the inner wall of the groove opened by the cover 81, and a linkage block 892 is sleeved on the linkage column 891, and a linkage rod 893 is hinged on the linkage block 892; a sleeve block 894, which is sleeved on the slide rod 88 and hinged to the linkage rod 893, and a threaded plate 895 threadedly connected to the screw rod 85 is fixed on the sleeve block 894; a connecting rod 896, one end of which is fixedly connected to the sleeve block 894, and the other end of the support ring 810 is fixedly connected to the connecting rod 896.

[0033] The rotation of the screw rod 85 can make the threaded plate 895 push the sleeve block 894 on one side to slide on the slide rod 88. The movement of the sleeve block 894 on one side makes the linkage rod 893 on one side push the linkage block 892 to slide along the linkage column 891. The linkage block 892 can make the linkage rod 893 on the other side pull the sleeve block 894 on the other side to slide along the slide rod 88. The sleeve blocks 894 on both sides can drive the support rings 810 on both sides to approach each other through the connecting rod 896, thereby driving the clamping block 811 to press and fix the crystalline silicon material for easy cleaning.

[0034] like Figure 1 As shown, as a preferred embodiment of the present invention, the cleaning mechanism 9 includes: a cleaning tank 91, which is fixedly mounted on the base plate 1, and a recovery tank 92 fixed on the base plate 1 is provided on one side of the cleaning tank 91, and a drain plate 93 is fixedly provided in the recovery tank 92, and the drain plate 93 is provided with a through hole; a water adding bucket 94, which is fixedly mounted on the upper side of the cleaning tank 91, and water can be added to the cleaning tank 91 from the water adding bucket 94, and a stirring mechanism 95 for stirring the water is installed in the cleaning tank 91, and the driven gear 814 can engage with the stirring mechanism 95; a drainage pipe 96, both ends of which are respectively connected to the lower sides of the cleaning tank 91 and the recovery tank 92, and an outlet pipe 97 is fixedly provided on the drainage pipe 96, and valves 98 installed on the drainage pipe 96 are provided on both sides of the outlet pipe 97.

[0035] During cleaning, after the clamping mechanism 8 brings the crystalline silicon material into the cleaning tank 91, the stirring mechanism 95 engages with the driven gear 814, and the stirring mechanism 95 is turned on. The stirring mechanism 95 can stir the cleaning agent, and at the same time, the stirring mechanism 95 drives the driven gear 814 to rotate, thereby driving the clamping block 811 to rotate stably on the support ring 810, so that the crystalline silicon material can be turned over, and then the cleaning of the crystalline silicon material can be accelerated. The cleaned crystalline silicon material can be clamped by the mechanism 8 and placed on the drain plate 93 of the recovery tank 92 for draining. The cleaning agent can be added from the water adding bucket 94 to the cleaning tank 91 for storage. If the cleaning agent needs to be discharged and replaced, the valve 98 can be opened, and the cleaning agent can be discharged through the drainage pipe 96 and the outlet pipe 97.

[0036] like Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the stirring mechanism 95 includes: a protective box 951, which is fixedly installed in the cleaning tank 91, and a second power member 952 is fixedly installed in the protective box 951, and the output shaft of the second power member 952 is fixedly connected to the third bevel gear 953; a rotating rod 954, which is rotatably set on the protective box 951 and has both ends rotatably connected to the inner wall of the cleaning tank 91, and a fourth bevel gear 955 engaged with the third bevel gear 953 is fixed on the rotating rod 954; a stirring plate 956, which is fixedly installed on the rotating rod 954 and distributed on both sides of the protective box 951, and a driving gear 957 fixed on the rotating rod 954 is provided on both sides of the stirring plate 956, and the driven gear 814 can engage with the driving gear 957.

[0037] When stirring the cleaning agent, the second power member 952 is turned on, and the output shaft of the second power member 952 drives the third bevel gear 953 to rotate, and the third bevel gear 953 drives the fourth bevel gear 955 and the rotating rod 954 to rotate. The rotation of the rotating rod 954 can drive the stirring plate 956 to stir the cleaning agent, thereby driving the driving gear 957 to rotate. The rotation of the driving gear 957 can drive the driven gear 814 to rotate, thereby driving the clamping block 811 to rotate stably on the support ring 810, so that the crystalline silicon material can be turned over, thereby improving the cleaning rate of the crystalline silicon material.
