[0002] The crushing mode of finished silicon plate of industrial silicon includes jaw crusher crushing mode and finishing crushing mode. The traditional jaw crusher crushing mode generally uses the jaw crusher arranged on the ground to complete the extrusion crushing of the complete silicon plate through the extrusion action of the jaw plate. The finishing crushing mode completes the crushing of the complete silicon plate by using the finishing crusher arranged on the ground. In the process of crushing the silicon material by the above two modes, dust (industrial silicon powder) is generated. However, since the above two modes do not perform closed dust collection treatment on the related crushing device, a large amount of dust will overflow from the dust outlet of the crushing device to the workshop, polluting the working environment of the workshop.

[0052] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0053] Embodiment 1

[0054] The utility model embodiment provides a kind of silicon material totally enclosed crushing system, please refer to Figures 1-3It comprises a closed assembly and a crushing assembly, wherein the closed assembly has a sealing cover and a hopper 5; the crushing assembly has a vibrating screen 61 and a crusher 62.

[0055] Specifically,

[0056] The closed assembly comprises the sealing cover and the hopper 5. The hopper 5 is installed at the bottom end of the sealing cover and communicates with the sealing cover.

[0057] The sealing cover is installed on the ground and comprises a cover body 3 and a sliding door assembly. The cover body 3 is internally provided with a dust removal passage 40, and the dust removal passage 40 is externally connected with a negative pressure dust remover 41. The cover body 3 is provided with a containing space 31 from the bottom to the top, and the containing space 31 communicates with the dust removal passage 40. A feeding through hole 30 is formed in the side wall of the cover body, so that the containing space 31 in the cover body communicates with the outside, so that the pushing machine 1 can push the silicon material into the containing space 31 through the feeding through hole 30. The sliding door assembly is installed on the inner side wall of the cover body 3 and is used for opening or blocking the feeding through hole 30, and comprises a mounting seat 35, a guide rod 33, a door body 32 and a driving device 34.

[0058] The mounting seat 35 is arranged on the front and rear sides of the feeding through hole 30. One end of each mounting seat 35 is bolted to the ground, and the other end penetrates the side wall of the cover body and is arranged in the cover body 3.

[0059] The guide rod 33 is arranged in the vertical direction in the inner wall area of the cover body outside the feeding through hole 30 and is rotationally connected to the mounting seat 35. Preferably, the guide rod 33 is provided with two guide rods 33 arranged on the front and rear sides of the feeding through hole 30.

[0060] The door body 32 can be arranged at the feeding through hole 30 in the initial position of the cover body 3 to achieve complete blocking or partial blocking of the feeding through hole 30, or can be arranged above the feeding through hole 30 to make the feeding through hole 30 in a completely open state. The door body 32 comprises a shielding plate 320 and a convex plate 321. The shielding plate 320 is arranged to match the feeding through hole 30, that is, the size of the shielding plate 320 is equal to or slightly larger than the feeding through hole 30, so that the shielding plate 320 can completely block the feeding through hole 30. Two convex plates 321 are arranged on the front and rear sides of the shielding plate 320 respectively. The convex plate 321 is arranged above the mounting seat 35 and is penetrated by the guide rod 33, and the convex plate 321 is threadedly connected with the guide rod 33.

[0061] The driving device 34 is matched with the guide rod 33, that is, the number of the driving device 34 is same as that of the guide rod 33. Each driving device 34 comprises a driven wheel 342, a driving wheel 344, a transmission belt 343 and a motor 341. The driven wheel 342 is rotationally connected to the top end of the guide rod 33, the motor 341 is installed on the inner wall of the cover body 3 through a connecting seat 340, and the driving wheel 344 is installed on the active end of the motor 341. A clamping groove matched with the transmission belt is formed on the outer wall of the driving wheel 344 and the driven wheel 342, so that the transmission belt 343 can be sleeved on the outer wall of the driving wheel 344 and the driven wheel 342 at the same time. When the motor 341 is started, the driving of the motor 341 drives the driving wheel 344 to rotate, and the transmission belt 343 is driven to rotate the driven wheel 342, so that the guide rod 33 also rotates in the same direction, and further drives the lug 321 to move along the extension direction of the guide rod 33. All the motors 341 of the driving device 34 drive the corresponding driving wheels 344 to rotate synchronously, so as to ensure that the lug 321 can move synchronously along the extension direction of the guide rod 33.

[0062] According to the different positions of the aforementioned door body 32 in the cover body 3 in the initial state, the corresponding driving device 34 cooperates with the operation mode of the door body 32 as follows:

[0063] If the initial state of the feeding hole 30 is completely blocked or partially blocked, first start the motor 341, drive the driving wheel 344 to rotate by the motor 341, drive the driven wheel 342 to rotate through the transmission belt 343, so that the guide rod 33 rotates, and further drives the door body 32 to move upward along the extension direction of the guide rod, until the feeding hole 30 is completely opened. At this time, the pusher 1 can push the silicon material into the cover body 3 through the feeding hole 30. When subsequent blocking of the feeding hole 30 is needed, the guide rod 33 can be driven to rotate in the opposite direction by the motor 341, so as to drive the door body 32 to move downward along the extension direction of the guide rod.

[0064] If the initial state of the feeding hole 30 is completely opened, the silicon material can be directly pushed into the cover body 3 through the feeding hole 30 by the pusher 1. When subsequent blocking of the feeding hole 30 is needed, the guide rod 33 can be driven to rotate by starting the motor 341, so as to drive the door body 32 to move downward along the extension direction of the guide rod.

[0065] The hopper 5 is movably installed at the bottom end of the cover body, and is communicated with the cover body 3. When the cover body 3 is installed on the ground, a crushing channel 60 is formed on the ground area surrounded by the cover body 3, so that the hopper 5 movably installed at the bottom end of the cover body can be arranged below the ground. The hopper 5 can receive the silicon material entering the cover body and transport it to the crushing channel 60.

[0066] The crushing assembly arranged in the crushing channel 60 includes a vibrating screen 61 and a crusher 62. The connecting line direction from the vibrating screen inlet to the vibrating screen outlet is obliquely downward. The outlet of the hopper 5 is connected with the inlet of the vibrating screen. The outlet of the vibrating screen leads to the crusher 62. The crusher 62 can be a jaw crusher.

[0067] The silicon material transmitted from the hopper 5 to the crushing channel 60 is buffered by the vibrating screen 61 and then obliquely transmitted to the crusher 62 along the vibration direction of the vibrating screen 61. When the crusher 62 is ready to crush the silicon material, the material pushing machine 1 can be temporarily stopped to push the silicon material into the cover 3, and the working state of the motor 341 is controlled to control the rotating direction of the guide rod 33, so that the door body 32 moves downward along the extension direction of the guide rod to completely block the feeding hole 30, thereby avoiding the overflow of a large amount of dust generated in the crushing process of the silicon material.

[0068] A transmission channel 63 is arranged below the crushing channel 60, and a transmission device 64 is arranged in the transmission channel 63. A plurality of discharge holes 600 are arranged through the bottom surface of the crushing channel downward, and are used for communication between the crushing channel 60 and the transmission channel 63. The discharge holes 600 are arranged in the bottom surface region of the crushing channel where the crusher 62 is arranged, and the outlet of the discharge hole leads to the input end of the transmission device. The silicon material crushed in the crusher 62 falls to the bottom surface of the crushing channel and is transmitted to the input end of the transmission device through the discharge hole 600, and is then transmitted outward through the transmission device 63.

[0069] Based on the above embodiment, the working mode of the present application is as follows (taking the example that the position of the door body 32 in the initial state completely opens the feeding hole 30):

[0070] After the material pushing machine 1 pushes the silicon material into the cover 3 through the feeding hole 30, the silicon material falls to the vibrating screen 61 from the hopper 5 and is transmitted to the crusher 62 along the vibration direction of the vibrating screen 61 until the crusher 62 is filled with the silicon material. When the crusher 62 is ready to crush the silicon material, the material pushing machine 1 can be temporarily stopped to push the silicon material into the cover 3, the motor 341 is started, and the working state of the motor 341 is controlled to move the door body 32 downward to the fully closed state of the cover 3. Then, the crusher 62 is started to crush the silicon material in the crusher 62. After the crushing is completed, the crusher 62 is closed, and the working state of the motor 341 is controlled to move the door body 32 upward to completely open the feeding hole 30, so as to facilitate the feeding of the subsequent silicon material to be crushed in the cover.

[0071] Based on the above embodiment, the advantages of the present application are as follows:

[0072] Through the cooperation of the driving device 34 and the door body 32, the silicon material can enter the cover body through the feeding through hole 30 and be transmitted to the crusher 62, and the door body 32 is lowered in advance to completely block the feeding through hole 30 when the crusher 62 is ready to crush the material, thereby avoiding the dust overflow during the crushing of the silicon material, greatly reducing the dust content in the workshop and ensuring the working environment of the personnel. A transmission channel 63 is arranged below the crushing channel 60, and a transmission device 64 is arranged in the transmission channel 63. The crushing channel 60 and the transmission channel 63 are communicated through the discharge hole 600, which is beneficial to further dust reduction.

[0073] Embodiment 2

[0074] In order to further improve the automation and convenience of the crushing dust reduction during the operation of the fully-closed silicon material crushing system, the crusher of the present application is also provided with a material level control device, please refer to Figures 1-4 The material level control device comprises a material level sensor 70 and a control processor 71.

[0075] The material level sensor 70 is installed in the crusher 62 for sensing the material level of the silicon material in the crusher 62. The control processor 71 is installed on the outer wall of the crusher 62, the output end of the material level sensor is electrically connected with the input end of the control processor, and the output end of the control processor is electrically connected with the input end of the motor and the input end of the crusher.

[0076] If the initial state of the feeding through hole 30 is completely blocked or partially blocked, the working principle of the material level control device is as follows:

[0077] The empty position signal received by the material level sensor 70 is transmitted to the control processor 71, and the control processor 71 controls the start of the motor 341 to drive the rotation of the guide rod 33 to move the door body 32 upward to completely open the feeding through hole 30. At this time, the pusher 1 pushes the silicon material into the cover body 3 through the feeding through hole 30, and then falls to the vibrating screen 61 through the funnel 5, and then enters the crusher under the vibration of the vibrating screen 61. When the silicon material in the crusher is full, the full position signal received by the material level sensor 70 is transmitted to the control processor 71 for processing, and then the control processor 71 controls the working state of the motor 341, and then drives the guide rod 33 to rotate in the opposite direction, so that the door body 32 moves downward to completely block the feeding through hole 30, and then controls the start of the crusher 62, so that the silicon material can be crushed in the crusher in a fully-closed environment. In the above process, the pusher operator sees that the door body 32 moves downward and will not continue to push the material into the cover body 3.

[0078] When the silicon material in the crusher is crushed, the empty position signal received by the material level sensor 70 is transmitted to the control processor 71, which controls the crusher 62 to be closed and the running state of the motor 341 to drive the rotation of the guide rod 33, so that the door body 32 moves upward to the feeding hole 30 to be completely open, so as to facilitate the feeding of the subsequent silicon material to be crushed in the cover body.

[0079] If the initial state of the feeding hole 30 is completely open, the working principle of the material level control device is:

[0080] After the pusher 1 pushes the silicon material into the cover body 3 through the feeding hole 30, it falls to the vibrating screen 61 through the funnel 5, and then enters the crusher under the vibration of the vibrating screen 61. When the silicon material in the crusher is full, the full position signal received by the material level sensor 70 is transmitted to the control processor 71 for processing, and then the control processor 71 controls the working state of the motor 341, and then drives the rotation of the guide rod 33, so that the door body 32 moves downward to completely block the feeding hole 30, and then controls the crusher 62 to start, so that the silicon material can be crushed in the crusher in a fully closed environment. In the above process, the pusher operator can see that the door body moves downward, so he will not continue to push the material into the cover body.

[0081] When the silicon material in the crusher is crushed, the empty position signal received by the material level sensor 70 is transmitted to the control processor 71, which controls the crusher 62 to be closed and the running state of the motor 341 to drive the rotation of the guide rod 33, so that the door body 32 moves upward to the feeding hole 30 to be completely open, so as to facilitate the feeding of the subsequent silicon material to be crushed in the cover body.
