DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0026] In the prior art, the cleaning effect of the silicon material cleaning system is poor, which causes the silicon material to contain impurities, so that the products produced later cannot meet the original standards. The embodiment of the present invention provides the following solution:

[0027] like Figures 1 to 6As shown, an embodiment of the present invention provides a silicon material cleaning system, including a surface pretreatment mechanism 1, a cleaning mechanism 2, a liquid supply mechanism and a drying mechanism 3, and the surface pretreatment mechanism 1, the cleaning mechanism 2 and the drying mechanism 3 are connected in sequence. The liquid supply mechanism includes a degreasing agent circulation tank, an acid liquid circulation tank and a high-purity water circulation tank, the cleaning mechanism 2 includes a degreasing tank body 21, an ultrasonic rinsing tank body 22, at least one rinsing tank body 23 and at least one pickling tank body 24, and the cleaning mechanism 2 and the drying mechanism 3 are both provided with at least one material conveying mechanism 5 for driving the material basket 4 to move and lift. The liquid output end of the degreasing agent circulation tank is connected to the liquid input end of the degreasing tank body 21, the liquid output end of the acid liquid circulation tank is connected to the liquid input end of the pickling tank body 24, and the liquid output end of the high-purity water circulation tank is respectively connected to the liquid input ends of the ultrasonic rinsing tank body 22 and the rinse tank body 23.

[0028] It should be noted that the silicon material first enters the surface pretreatment mechanism 1, which is used to remove the oxidized part, burr part and visible dirt on the surface of the silicon material. Then the silicon material enters the cleaning mechanism 2, and the material basket 4 containing the silicon material is moved to the degreasing tank 21, the ultrasonic rinsing tank 22, the flushing tank 23 and the pickling tank 24 for cleaning through the material conveying mechanism 5. The degreasing tank 21 is injected with degreasing agent through the degreasing agent circulation tank to degrease and clean the silicon material. After the ultrasonic rinsing tank 22 is injected with pure water through the high-purity water circulation tank, the silicon material is ultrasonically cleaned. The ultrasonic transducer in the ultrasonic rinsing tank 22 converts the acoustic energy into mechanical energy, and a cavitation effect is generated in the liquid. When the cavitation bubble suddenly closes, the shock wave emitted can generate a huge force around it, directly and repeatedly impacting the contamination layer, on the one hand destroying the adsorption of dirt and the surface of the cleaning part, and on the other hand destroying the contamination layer and separating from the surface of the cleaning part to achieve the cleaning effect. The rinse tank 23 is injected with pure water through a high-purity water circulation tank to clean the silicon material. The pickling tank 24 is injected with pickling liquid through an acid liquid circulation tank to pickle the silicon material. Finally, the cleaned silicon material is sent to the drying mechanism 3 for drying. The cleaning effect of the silicon material is improved through the overall surface pretreatment and cleaning.

[0029] In some embodiments, the surface pretreatment mechanism 1 includes a sandblasting device 11 , a water spraying device 12 , and a nitrogen spraying device 13 , and the sandblasting device 11 , the water spraying device 12 , and the nitrogen spraying device 13 are all connected to a cartridge dust collector 14 .

[0030] It should be noted that a sandblasting gun is provided in the sandblasting device 11. When the silicon material is transported to the sandblasting device 11, the sandblasting gun sandblasts the silicon material to remove surface impurities, and the generated dust is sent to the filter cartridge dust collector 14 for filtration to prevent the environment from being polluted by wind and dust. A water spraying gun is provided in the water spraying device 12. When the silicon material is transported to the water spraying device 12, the water spraying gun sprays water on the silicon material to remove surface impurities and clean it, and the generated dust is sent to the filter cartridge dust collector 14 for filtration to prevent the environment from being polluted by wind and dust. A nitrogen spraying gun is provided in the nitrogen spraying device 13. The nitrogen spraying gun sprays nitrogen gas on the silicon material to remove moisture and other impurities on the surface of the silicon material to prevent the silicon material from being oxidized or otherwise polluted.

[0032] It should be noted that the horizontal filter cartridge installation structure is adopted so that the airflow inside the filter cartridge dust collector 14 flows from top to bottom, which is consistent with the dust settling direction, thereby improving the dust filtering performance. The high-pressure backflush pipe 145 is connected to the high-pressure gas output device, and the high-pressure gas is ejected through the air blowing head 1451 to backflush the horizontal filter cartridge 142, thereby cleaning the horizontal filter cartridge 142.

[0033] In some embodiments, the input end and the output end of the cleaning mechanism 2 are both provided with a roller conveyor 6, and the input end and the output end of the drying mechanism 3 are respectively provided with a roller conveyor 6 and a material conveying vehicle 7.

[0035] In some embodiments, the material conveying mechanism 5 includes a slide rail 51 and a movable lifting device 52 installed on the slide rail 51 , and a lifting end of the movable lifting device 52 is detachably connected to the material basket 4 .

[0036] It should be noted that the mobile lifting device 52 moves laterally via the slide rail 51 , so as to deliver the material basket 4 into a suitable cleaning tank or drying tank. After being delivered into the suitable tank, the material basket 4 is separated from the mobile lifting device 52 .

[0037] In some embodiments, the mobile lifting device 52 includes a top connecting plate 521, a middle connecting plate 522, a bottom connecting plate 523, a first lateral plate 524, a second lateral plate 525 and a rotating hanging plate 526. The bottom ends of the first lateral plate 524 are connected to sliders 527, and the bottom ends of the second lateral plate 525 are connected to sliders 527. The sliders 527 are connected to the slide rails 51. The middle connecting plate 522 is provided with a plurality of linear bearings 5221, and the linear bearings 5221 are provided with linear shafts 5222. One end of the linear shaft 5222 is connected to the top connecting plate 521, and the other end of the linear shaft 5222 is connected to the bottom connecting plate 523. The bottom ends of the first lateral plate 524 are connected to the bottom connecting plate 523 through first connecting columns 528, and the bottom ends of the second lateral plate 525 are connected to the bottom connecting plate 523 through first connecting columns 528. Through holes are respectively provided on both sides of the bottom connecting plate 523, and second connecting columns 5223 are respectively connected on both sides of the middle connecting plate 522, and one end of the second connecting column 5223 passes through the through hole and is connected to the rotary hanging plate 526. The middle connecting plate 522 is installed with a driving motor 5224 and a screw seat 5225, and the motor shaft of the driving motor 5224 is connected to a first synchronous pulley 5226; a screw 5227 is matched and connected in the screw seat 5225, and one end of the screw is connected to a second synchronous pulley 5228, and the other end of the screw 5227 is rotatably connected to the bottom connecting plate 523, and the first synchronous pulley 5226 is connected to the second synchronous pulley 5228 through a synchronous belt. Hooks 5261 are provided on both sides of the rotary hanging plate 526, and hooks 41 adapted to the hooks are provided on both sides of the material basket 4.

[0038] It should be noted that the entire mobile lifting device 52 can move horizontally on the slide rail 51 by cooperating with the slider 527 and the slide rail 51. When the driving motor 5224 rotates, it drives the first synchronous pulley 5226 to rotate, and then drives the second synchronous pulley 5228 to rotate through the synchronous belt, thereby driving the screw rod 5227 to rotate in the screw rod seat 5225, so that the middle connecting plate 522 is lifted and moved, thereby driving the rotating hanging plate 526 to be lifted and moved, so that the material basket 4 is lifted and moved. After the material basket 4 is placed in an appropriate slot, the rotating hanging plate 526 is moved horizontally, so that the hook 5261 is separated from the hook 41. When the material basket 4 needs to be pulled up, the rotating hanging plate 526 is moved so that the hook 5261 is in the matching position of the hook 41, so as to be connected with the hook 41 of the material basket 4, so as to facilitate the lifting of the material basket 4.

[0039] In some embodiments, the cleaning mechanism 2 includes an integral bracket 25, and a vertical plate 26 corresponding to the degreasing tank 21, the ultrasonic rinsing tank 22, the flushing tank 23, and the pickling tank 24 is provided at the bottom of the integral bracket 25.

[0043] In some embodiments, the degreasing agent circulation tank is provided with corresponding pump valve group, liquid level control system and the device used for degreasing agent configuration to ensure the continuous operation of the degreasing process of the cleaning machine. A waste liquid collection tank and corresponding pump valve group and liquid level control system are provided to centrally collect the waste liquid sent out.
