Description

Technical Field

[0001] The present invention relates to the technical field of impurity removal equipment, and more specifically to an impurity removal equipment for raw materials in silicon material production. Background Art

[0002] The raw material impurity removal equipment is one of the impurity removal devices for silicon material production. The common raw material removal equipment mainly consists of a main structure, a power and transmission system, a screening device, a rubber shock-absorbing bracket, and an auxiliary system, etc. The specific process of raw material impurity removal equipment for silicon material production is as follows: First, the feeding stage: uniform feeding: silicon powder enters the screening box through a vibrating feeder or a screw conveyor; Second, the swinging screening stage: the motor drives the eccentric mechanism to make the screening body perform an artificial swinging motion, and drives the silicon material to perform impurity removal operations through the screening device; Third, discharging and collection: classified discharging: each layer of sieve mesh corresponds to an independent discharging port, and coarse, medium, and fine silicon powders enter different collection bins respectively;

[0003] However, during the later process of silicon material production, we found that the main structure would tilt as a whole during use. During the later investigation, we found that the main reasons for this phenomenon are as follows: First, the rubber shock-absorbing bracket is deformed. The main reason for this phenomenon is that the above rubber shock-absorbing bracket operates overloaded, resulting in a bending deformation phenomenon in its middle position; Second, the bolts at the connection end of the rubber shock-absorbing bracket fall off. The main reason for this phenomenon is that the pre-tightening force is too large or the main structure is in a vibrating state for a long time, resulting in the bolts of its bolt assembly becoming loose and falling off; When the above situation occurs, it is extremely easy to cause the main structure to tilt, resulting in the invalidity of silicon material filtration, and at the same time causing the main structure to tilt and fall, causing certain harm to the on-site workers;

[0004] Therefore, now we urgently need an impurity removal equipment for raw materials in silicon material production to solve the above-mentioned technical problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an impurity removal equipment for raw materials in silicon material production to solve the problems existing in the above background art.

[0006] The present invention provides the following technical solutions: An impurity removal equipment for raw materials in silicon material production, comprising:

[0007] An electric control vibrating filter screen for filtering and removing internal impurities of silicon materials. The electric control vibrating filter screen includes a raw material output end, and a discharge pipe is installed at the raw material output end for outputting the raw materials after impurity removal. A power supply system is installed on the side of the bottom of the electric control vibrating filter screen for providing power for raw material screening;

[0008] At the four corners on the side of the electric control vibrating screen, two sets of upper and lower brackets are successively installed. On the opposite inner surfaces of the two sets of brackets, rubber supports are vertically fixed. On the outer walls of the rubber supports, micro plates are successively and vertically installed. On the side of the micro plate far from the rubber support, a protective layer is vertically installed. On the outer wall of the protective layer, a rubber partition is vertically installed. At the position of the rubber partition far from the protective layer, an induction layer is vertically installed. When the outer side of the induction layer, the outer side of the protective layer, and the inner side of the induction layer are connected to the opposite inner surfaces of the two sets of brackets, two independent sealed spaces can be formed;

[0009] A monitoring system is arranged inside the electric control vibrating screen for monitoring the bending state of the whole rubber support.

The compressed air in another group of flow spaces is input into a group of flow spaces formed by the opposite surfaces of another group of brackets through a second auxiliary micro-delivery pipe. The compressed air circulates in each group of flow spaces in turn until the compressed air in the corresponding another group of flow spaces is extracted and recycled by the second air pump, thereby driving the compressed air in each group to circulate in each group of flow spaces;

[0014] Limit support plates are installed on the opposite side surfaces at both ends of the two induction layers.

A common spring assembly is arranged between the opposite inner side surfaces of the auxiliary sliding plate and the gripping plate in a direction perpendicular to the opposite surfaces of the gripping plate and the auxiliary sliding plate. The spring assembly is fixedly installed at the corresponding positions on the inner side walls in an equidistant arrangement manner.

[0016] Preferably, a fourth air pressure sensor is installed inside the first hollow plate. The fourth air pressure sensor collects the fourth air pressure data inside the first hollow plate and transmits it to the monitoring system for judging the real-time connection state between the rubber bearing and the bracket. A first auxiliary delivery pipe is installed through the inner part of the side of the first hollow plate. One end of the first auxiliary delivery pipe away from the first hollow plate is installed in the corresponding flow space;

[0017] First fixing rings are installed on the outer side surfaces of two adjacent induction layers near the middle position. Auxiliary limit plates are installed on both sides of the first fixing ring away from the induction layer.

[0018] Preferably, a transmission rod is installed at one end of the auxiliary limit plate away from the transmission plate. The side surface of the transmission rod is installed in the middle area of the side surface of the transmission plate. A transmission rod is installed on the side surface of the transmission plate away from the first fixing ring.

The servo motor has a transmission output end, and the transmission output end is on the side surface of the transmission rod for driving the transmission rod to rotate;

[0019] On the outer side of the middle position between two adjacent groups of the induction layers, a first fixing ring is installed. On the opposite sides of the two first fixing rings, a second fixing ring is installed. On the sides of the two second fixing rings, sliders are installed. A second hollow plate is sleeved on the outer walls of the two sliders at their relative positions. The positions of the two sliders in the corresponding second hollow plate are opposite. On the opposite sides of the two sliders, a plurality of groups of first springs are vertically installed together. On the inner wall of the bottom of the second hollow plate, a first air pressure sensor is installed, which is used to collect the first air pressure data inside the second hollow plate and transmit it to the monitoring system. A second auxiliary conveying pipe is installed through the inner wall of the top of the second hollow plate. One end of the second auxiliary conveying pipe away from the second hollow plate is arranged in the corresponding flow space, which is used to convey the compressed air in the corresponding flow space into the interior of the second hollow plate;

[0020] In one group of the sealed spaces, a second input pipe is installed. One end of the second input pipe away from one group of the sealed spaces penetrates an induction plate. In the middle area of the induction plate, a partition is installed, which divides the interior of the induction plate into two independent monitoring spaces. One end of the second input pipe is arranged in one group of the monitoring spaces. On the inner side wall of the induction plate near one group of the monitoring spaces, a third air pressure sensor is installed, which is used to monitor the third air pressure data generated in one group of the monitoring spaces and transmit it to the monitoring system. In the other group of the monitoring spaces, a first input pipe is installed. One end of the first input pipe away from the induction plate is installed in the other group of the sealed spaces, and on the inner side wall of the induction plate near the other group of the monitoring spaces, a second air pressure sensor is installed. The second air pressure sensor detects the second air pressure data generated in the other group of the sealed spaces and transmits it to the monitoring system.

[0021] Preferably, the monitoring system includes a threshold unit, a temperature adjustment unit, and an early warning unit;

[0022] When the threshold unit simulates the state where the bracket and the rubber bearing are fixedly connected, the simulated fourth air pressure data generated by the fourth air pressure sensor. When the threshold unit simulates the normal non-deformed state of the rubber bearing, the simulated first air pressure data, the simulated second air pressure data, and the simulated third air pressure data generated by the first air pressure sensor, the second air pressure sensor, and the third air pressure sensor. The threshold module integrates the simulated first air pressure data, the simulated second air pressure data, the simulated third air pressure data, and the simulated fourth air pressure data to form a threshold range;

[0023] The monitoring system compares the real-time fourth air pressure data with the threshold range. When the real-time air pressure data is not within the threshold range, it is determined that there is an incomplete connection between the bracket and the rubber bearing;

[0024] The monitoring system compares the real-time first air pressure data, real-time second air pressure data, and real-time third air pressure data with the threshold range. When the real-time first air pressure data, real-time second air pressure data, and real-time third air pressure data are not within the threshold range, it is determined that the rubber bearing is in an inclined state;

[0025] The temperature adjustment unit inputs the critical heat-resistant temperature value of the rubber bearing manually. The temperature adjustment unit receives the real-time temperature data and compares the real-time temperature data with the critical heat-resistant temperature value. When the real-time temperature data is greater than the critical heat-resistant temperature value, it is determined that the temperature on the outer surface of the rubber bearing exceeds the limit.

[0026] The technical effects and advantages of the present invention:

[0027] When the monitoring system of the present invention determines that the two groups of rubber bearings are in a front-back inclined deformation state relative to the electric control vibrating screen, the servo motor inputs a stable working current, drives the transmission rod to rotate by a corresponding degree, and controls the rubber bearing in the inclined state to move away from its inclined angle direction, so as to achieve the effect of temporarily adjusting the rubber bearing in the inclined state, and avoid the overall inclination of the electric control vibrating screen caused by the inclination of some rubber bearings, which may cause certain damage to its internal components and pose certain safety hazards to on-site workers.

[0028] When the monitoring system of the present invention determines that the two groups of rubber bearings are in a left-right inclined deformation state relative to the electric control vibrating screen, the first air pump and the second air pump input corresponding stable currents, generate corresponding compressed air, and input it into the corresponding second hollow plate through the corresponding flow space and the corresponding second auxiliary conveying pipe, driving the two groups of sliders to perform corresponding position adjustments, so as to adjust the real-time positions of the two groups of rubber bearings in the inclined state, thereby achieving the effect of temporarily adjusting the rubber bearings in the inclined state, and avoiding the overall inclination of the electric control vibrating screen caused by the inclination of some rubber bearings, which may cause certain damage to its internal components and pose certain safety hazards to on-site workers.

Detailed implementation manners

[0038] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and an equipment for removing raw material impurities in the production of silicon materials according to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0039] Referring to Figures 1 to 3 shown, the present invention provides an equipment for removing raw material impurities in the production of silicon materials, including an electric control vibrating filter screen 1 for filtering and removing internal impurities of silicon materials. The electric control vibrating filter screen 1 includes a raw material output end, and a discharge pipe 101 is installed at the raw material output end for outputting the raw material after impurity removal. A power supply system 102 is installed on the side of the bottom of the electric control vibrating filter screen 1 for providing power for raw material screening;

[0040] At the four corners on the side of the electric control vibrating screen 1, two sets of brackets 103 are successively installed up and down. On the opposite inner surfaces of the two sets of brackets 103, rubber supports 107 are vertically fixed. On the outer walls of the rubber supports 107, micro plates are successively vertically installed. On the side of the micro plate far from the rubber support 107, a protective layer 105 is vertically installed. On the outer wall of the protective layer 105, a rubber partition 106 is vertically installed. At a position where the rubber partition 106 is far from the protective layer 105, an induction layer 104 is vertically installed. When the outer side surface of the induction layer 104, the outer side surface of the protective layer 105, and the inner side surface of the induction layer 104 are connected to the opposite inner surfaces of the two sets of brackets 103, two independent sealed spaces can be formed;

[0041] A monitoring system is arranged inside the electric control vibrating screen 1 to monitor the bending state of the rubber support 107 as a whole.

[0042] In the embodiment of the present application, when the inner side surface of the protective layer 105 and the outer side surface of the rubber support 107 are connected to the opposite inner surfaces of the two sets of brackets 103, an independent sealed flow space can be formed. And a temperature sensing device is installed on the inner side surface of the protective layer 105 to collect the temperature data in this flow space and transmit it to the monitoring system to judge the real-time temperature on the outer surface of the rubber support 107;

[0043] The induction layer 104 is made of a light-shielding rubber material, which is beneficial to reducing the direct irradiation of ultraviolet rays on the rubber support 107, thereby slowing down the aging and cracking speed of the rubber support 107 and increasing the overall service life of the rubber support 107 to a certain extent.

[0044] The specific working process of this application embodiment is as follows: The silicon material raw materials are conveyed into the electric control vibrating screen 1 through the raw material input end on the upper surface of the electric control vibrating screen 1. The power supply system 102 inputs a stable working current to drive the electric control vibrating screen 1 as a whole to be in a vibrating state, so as to facilitate the impurity removal operation of the silicon materials inside the electric control vibrating screen 1. The silicon materials after impurity removal are discharged through the discharge pipe 101.

[0045] Refer to Figures 1 to 3 As shown, the present invention provides a raw material impurity removal device for silicon material production. The number of rubber supports 107 vertically fixed on the opposite inner surfaces of each group of brackets 103 is two. A first air pump 2 is installed on the side surface at the bottom of the electric control vibrating screen 1. The first air pump 2 includes a gas output end, and a second conveying pipe 203 is installed at this gas output end. One end of the second conveying pipe 203 is installed inside a group of protective layers 105 close to its position to input compressed air into a group of flow spaces formed by a corresponding group of rubber supports 107 and a corresponding group of protective layers 105;

[0046] At the top of a group of the flow spaces, a first auxiliary micro-conveying pipe is installed through. One end of the first auxiliary micro-conveying pipe away from the group of flow spaces is arranged in another group of flow spaces. On the inner wall at the bottom position of the other group of flow spaces, a second auxiliary micro-conveying pipe is installed. One end of the second auxiliary micro-conveying pipe away from the other group of flow spaces is arranged in a corresponding group of flow spaces formed by the corresponding protective layer 105 and the corresponding rubber bearing 107 at the bottom of the adjacent support 103.

[0047] At the bottom of the electric control vibrating sieve 1, a second air pump 201 is installed near the first air pump 2. The second air pump 201 includes a gas input end, and a first conveying pipe 202 is installed at this gas input end. The first conveying pipe 202 away from this gas input end is installed in another adjacent group of flow spaces. Inside the first air pump 2, a temperature regulating device is provided for regulating the temperature of the compressed air output by the first air pump 2. The first air pump 2 inputs a stable working current, generates compressed air, and inputs it into a group of flow spaces through the second conveying pipe 203, and then inputs it into another group of flow spaces through the first auxiliary micro-conveying pipe. The compressed air in the other group of flow spaces is input into a group of flow spaces formed by the opposite surfaces of another group of supports 103 through the second auxiliary micro-conveying pipe. This compressed air circulates in each group of flow spaces in turn until the compressed air in the corresponding other group of flow spaces is extracted and recycled by the second air pump 201, so as to drive the compressed air in each group to circulate in each group of flow spaces.

[0048] In the embodiment of the present application, partial structures of the first auxiliary micro-conveying pipe, the second auxiliary micro-conveying pipe, the second conveying pipe 203, and the first conveying pipe 202 are all installed in the inner wall at the bottom of the electric control vibrating sieve 1.

[0049] The specific working process of this part of the embodiment of the application is as follows: When the monitoring system determines that the temperatures outside each rubber bearing 107 exceed the rated value, the first air pump 2 and the temperature regulating device input a stable working current, generate compressed air at the corresponding temperature, and input it into a group of flow spaces through the second conveying pipe 203, and then input it into another group of flow spaces through the first auxiliary micro-conveying pipe. The compressed air in the other group of flow spaces is input into a group of flow spaces formed by the opposite surfaces of another group of supports 103 through the second auxiliary micro-conveying pipe. This compressed air circulates in each group of flow spaces in turn until the compressed air in the corresponding other group of flow spaces is extracted and recycled by the second air pump 201, so as to drive the compressed air in each group to circulate in each group of flow spaces, and perform temperature regulation operations on the outer surfaces of each rubber bearing 107, avoiding the deformation and accelerated aging of each rubber bearing 107 due to the influence of the external temperature, and thus causing certain economic losses.

[0050] Refer to Figure 1 、Figure 3 and Figure 8 As shown, the present invention provides an equipment for removing raw material impurities in silicon material production. Limiting support plates 3 are installed on the opposite side surfaces at both ends of two groups of the induction layers 104. An auxiliary sliding plate 301 is movably sleeved on the inner wall of one side of the limiting support plate 3. A first torsion spring device is arranged at the connection between the auxiliary sliding plate 301 and the limiting support plate 3. One end outer wall of the auxiliary sliding plate 301 away from the limiting support plate 3 is movably sleeved with a first hollow plate 302. A gripping plate 303 is sleeved on the inner wall of one end of the first hollow plate 302 away from the auxiliary sliding plate 301. A common spring assembly is arranged between the opposite inner side surfaces of the auxiliary sliding plate 301 and the gripping plate 303 along the direction perpendicular to the opposite surfaces of the gripping plate 303 and the auxiliary sliding plate 301. The spring assembly is fixedly installed at the corresponding positions on the inner side walls of the two in an equidistant arrangement manner;

[0051] A fourth air pressure sensor is installed inside the first hollow plate 302. The fourth air pressure sensor collects the fourth air pressure data inside the first hollow plate 302 and transmits it to the monitoring system for judging the real-time connection state between the rubber bearing 107 and the support 103. One end of a first auxiliary conveying pipe 304 penetrates and is installed inside the side of the first hollow plate 302. The other end of the first auxiliary conveying pipe 304 away from the first hollow plate 302 is installed in the corresponding flow space.

[0052] In the embodiment of the present application, the specific working process of this part of the embodiment is as follows: after the rubber bearing 107 and the support 103 are installed, under the action of the first torsion spring device, the auxiliary sliding plate 301 and the first hollow plate 302 are driven to drive the gripping plate 303 to adhere to the outer surface of the support 103. When the connection between a certain group of the rubber bearing 107 and the support 103 is incomplete, after the monitoring system detects the above situation, the electromagnetic valves inside each group of the first auxiliary conveying pipes 304 are controlled to be in an open state. At the same time, the first air pump 2 and the second air pump 201 generate adsorption forces simultaneously and input them into each group of flow spaces, and pass through the inside of each group of the first hollow plates 302 to drive each group of the gripping plates 303 to apply an additional extrusion force to each group of the supports 103, so as to strengthen the connection force between each group of the supports 103 and the corresponding group of the rubber bearings 107, achieving the effect of temporarily limiting and fixing the support 103 and the rubber bearing 107 in an incompletely connected state.

[0053] Refer to Figures 1 to 7As shown in the figure, the present invention provides a raw material impurity removal device for silicon material production. On the outer sides of adjacent two groups of the induction layers 104 near their middle positions, a first fixing ring 4 is installed. On both sides of the first fixing ring 4 away from the induction layer 104, auxiliary limiting plates 408 are installed. At one end of the auxiliary limiting plate 408 away from the transmission plate 407, a transmission rod 409 is installed. The side of the transmission rod 409 is installed in the middle area of the side of the transmission plate 407. On the side of the transmission plate 407 away from the first fixing ring 4, a transmission rod 409 is installed. At one end of the transmission rod 409 away from the transmission plate 407, a clamping groove plate 411 is sleeved. On the side of the clamping groove plate 411, a servo motor 410 is installed. The servo motor 410 has a transmission output end, and this transmission output end is on the side of the transmission rod 409, and is used to drive the transmission rod 409 to perform a rotation operation;

[0054] On the outer sides of the middle positions of adjacent two groups of the induction layers 104, a first fixing ring 4 is installed. On the opposite sides of the two first fixing rings 4, a second fixing ring 401 is installed. On the sides of the two second fixing rings 401, sliding blocks 404 are installed. On the outer walls of the opposite positions of the two sliding blocks 404, a second hollow plate 402 is sleeved together. The positions of the two sliding blocks 404 arranged in the corresponding second hollow plate 402 are opposite. On the opposite sides of the two sliding blocks 404, a plurality of groups of first springs 406 are vertically installed together. On the inner wall of the bottom of the second hollow plate 402, a first air pressure sensor 405 is installed, which is used to collect the first air pressure data inside the second hollow plate 402 and transmit it to the monitoring system. Through the inner wall of the top of the second hollow plate 402, a second auxiliary conveying pipe 403 is installed. One end of the second auxiliary conveying pipe 403 away from the second hollow plate 402 is arranged in the corresponding flow space, and is used to convey the compressed air in the corresponding flow space to the inside of the second hollow plate 402.

[0055] In the embodiment of the present application, the first fixing ring 4 and the second fixing ring 401 are both made of elastic rubber materials. An electromagnetic valve is installed inside the second auxiliary conveying pipe 403, which is used to adjust the gas flow direction inside the second auxiliary conveying pipe 403.

[0056] The specific working process of this part of the embodiment of the application is as follows: When the monitoring system determines that the two rubber bearings 107 are in a front-back inclined deformation state relative to the electric control vibration filter screen 1, the servo motor 410 inputs a stable working current to drive the transmission rod 409 to rotate by a corresponding degree, and controls the rubber bearing 107 in the inclined state to move away from its inclined angle direction, so as to achieve the effect of temporarily adjusting the rubber bearing 107 in the inclined state, and avoid the overall inclination of the electric control vibration filter screen 1 caused by the inclination of some rubber bearings 107, which may cause certain damage to the internal components thereof and pose a certain safety hazard to the on-site workers;

[0057] When the monitoring system determines that the two groups of rubber bearings 107 are in a left - right inclined deformation state relative to the electric control vibrating screen 1, the first air pump 2 and the second air pump 201 input corresponding stable currents, generate corresponding compressed air, and input it into the corresponding second hollow plate 402 through the corresponding flow space and the corresponding second auxiliary conveying pipe 403, driving the two groups of sliders 404 to perform corresponding position adjustments, thereby adjusting the real - time positions of the two groups of rubber bearings 107 in an inclined state, so as to achieve the effect of temporarily adjusting the rubber bearings 107 in an inclined state, avoiding damage to the internal components of the electric control vibrating screen 1 caused by the inclination of some rubber bearings 107 and posing a certain safety hazard to on - site workers.

[0058] Refer to Figure 1 and Figures 3 to 5 As shown, a second input pipe 502 is installed in one group of the sealed spaces. One end of the second input pipe 502 away from the position of one group of sealed spaces penetrates an induction plate 5. A partition is installed in the middle area inside the induction plate 5, which divides the inside of the induction plate 5 into two independent monitoring spaces. One end of the second input pipe 502 is arranged in one group of monitoring spaces. A third air pressure sensor 504 is installed on the inner side wall of the induction plate 5 near its one group of monitoring spaces, used to monitor the third air pressure data generated in one group of monitoring spaces and transmit it to the monitoring system. The other group of monitoring spaces is installed with a first input pipe 501. One end of the first input pipe 501 away from the induction plate 5 is installed in the other group of sealed spaces, and a second air pressure sensor 503 is installed on the inner side wall of the induction plate 5 near its other group of monitoring spaces. The second air pressure sensor 503 detects the second air pressure data generated in the other group of sealed spaces and transmits it into the monitoring system.

[0059] In the embodiment of the present application, the two groups of sealed spaces are respectively located at the front and rear ends of the rubber bearing 107, so as to facilitate monitoring whether the inclination state of the rubber bearing 107 is front - rear inclination.

[0060] Refer to Figures 1 to 8 As shown, the present invention provides a raw material impurity removal device for silicon material production. The monitoring system includes a threshold unit, a temperature adjustment unit, and an early warning unit;

[0061] When the threshold unit simulates the analog fourth air pressure data generated by the fourth air pressure sensor when the simulation bracket 103 and the rubber bearing 107 are in a fixed connection state, and when the threshold unit simulates the rubber bearing 107 in a normal non-deformed state, the analog first air pressure data, the analog second air pressure data, and the analog third air pressure data generated by the first air pressure sensor 405, the second air pressure sensor 503, and the third air pressure sensor 504, the threshold module integrates the analog first air pressure data, the analog second air pressure data, the analog third air pressure data, and the analog fourth air pressure data to form a threshold range;

[0062] The monitoring system compares the real-time fourth air pressure data with the threshold range. When the real-time air pressure data is not within the threshold range, it is determined that the connection between the bracket 103 and the rubber bearing 107 is incomplete;

[0063] The monitoring system compares the real-time first air pressure data, the real-time second air pressure data, and the real-time third air pressure data with the threshold range. When the real-time first air pressure data, the real-time second air pressure data, and the real-time third air pressure data are not within the threshold range, it is determined that the rubber bearing 107 is in an inclined state;

[0064] The temperature adjustment unit inputs the critical heat-resistant temperature value of the rubber bearing 107 manually. The temperature adjustment unit receives the real-time temperature data and compares the real-time temperature data with the critical heat-resistant temperature value. When the real-time temperature data is greater than the critical heat-resistant temperature value, it is determined that the temperature on the outer surface of the rubber bearing 107 exceeds the limit.

[0065] In the embodiment of the present application, when the monitoring system determines that the real-time first air pressure data collected by the first air pressure sensor 405 is not within the threshold range, it is determined that the rubber bearing 107 is in a left-right inclined state. When the real-time first air pressure data is greater than the threshold range, it is determined that the two rubber bearings 107 are inclined towards each other. Similarly, when the first air pressure data is less than the threshold range, it is determined that the two rubber bearings 107 are inclined towards the opposite positions of each other;

[0066] The monitoring system compares the real-time second air pressure data and the real-time third air pressure data collected by the second air pressure sensor 503 and the third air pressure sensor 504 with the threshold range. When the real-time second air pressure data and the real-time third air pressure data are not within the threshold range, it is determined that the rubber bearing 107 is in a front-back inclined state. When the second air pressure data is less than the threshold range, it is determined that the rubber bearing 107 is inclined towards the position close to the electric control vibrating screen 1. When the third air pressure data is less than the threshold range, it is determined that the rubber bearing 107 is inclined towards the position away from the electric control vibrating screen 1.

[0067] The specific working process of the present application is as follows:

[0068] Impurity removal process: The silicon material raw material is conveyed to the inside of the electrically controlled vibrating sieve 1 through the raw material input end on the upper surface of the electrically controlled vibrating sieve 1. The power supply system 102 inputs a stable working current to drive the whole electrically controlled vibrating sieve 1 to be in a vibrating state, so as to facilitate the impurity removal operation of the silicon material inside the electrically controlled vibrating sieve 1. The silicon material after impurity removal is discharged through the discharge pipe 101;

[0069] Temperature adjustment process: When the monitoring system determines that the temperatures outside each group of rubber bearings 107 exceed the rated value, the first air pump 2 and the temperature adjustment device input a stable working current, and the compressed air corresponding to the temperature is input into a group of flow spaces through the second delivery pipe 203, and then input into another group of flow spaces through the first auxiliary micro-delivery pipe. The compressed air in another group of flow spaces is input into a group of flow spaces formed by the opposite surfaces of another group of brackets 103 through the second auxiliary micro-delivery pipe. The compressed air circulates in each group of flow spaces in turn until the compressed air in the corresponding another group of flow spaces is extracted and recycled by the second air pump 201, so as to drive the compressed air in each group to circulate in each group of flow spaces and perform temperature adjustment operations on the outer surfaces of each group of rubber bearings 107, avoiding the deformation and accelerated aging of each group of rubber bearings 107 due to the influence of the external temperature, and thus causing certain economic losses;

[0070] Position adjustment process: After the rubber bearing 107 and the bracket 103 are installed, under the action of the first torsion spring device, the auxiliary sliding plate 301 and the first hollow plate 302 are driven to drive the gripper plate 303 to adhere to the outer surface of the bracket 103. When there is an incomplete connection between a certain group of rubber bearings 107 and the bracket 103, after the monitoring system detects the above situation, it controls the solenoid valves inside each group of first auxiliary delivery pipes 304 to be in an open state. At the same time, the first air pump 2 and the second air pump 201 generate adsorption forces and input them into each group of flow spaces, and drive each group of gripper plates 303 to apply an additional extrusion force to each group of brackets 103 through the inside of each group of first hollow plates 302, so as to strengthen the connection force between each group of brackets 103 and the corresponding group of rubber bearings 107, achieving the effect of temporarily limiting and fixing the bracket 103 and the rubber bearing 107 in the state of incomplete connection;

[0071] When the monitoring system determines that the positions of the two groups of rubber bearings 107 relative to the electrically controlled vibrating sieve 1 are in a front-back inclined deformation state, the servo motor 410 inputs a stable working current, drives the transmission rod 409 to rotate by a corresponding degree, and controls the inclined rubber bearing 107 to move away from its inclined angle direction, so as to achieve the effect of temporarily adjusting the inclined rubber bearing 107, avoiding the overall inclination of the electrically controlled vibrating sieve 1 caused by the inclination of some rubber bearings 107, causing certain damage to its internal components and certain safety hazards to the on-site workers;

[0072] When the monitoring system determines that the two groups of rubber bearings 107 are in a left-right inclined deformation state relative to the electric control vibrating screen 1, the first air pump 2 and the second air pump 201 input corresponding stable currents to generate corresponding compressed air, which is then input into the corresponding second hollow plate 402 through the corresponding flow space and the corresponding second auxiliary conveying pipe 403 to drive the two groups of sliders 404 to adjust their corresponding positions, thereby adjusting the real-time positions of the two groups of rubber bearings 107 in an inclined state, so as to achieve the effect of temporarily adjusting the rubber bearings 107 in an inclined state, and avoid the overall inclination of the electric control vibrating screen 1 caused by the inclination of some rubber bearings 107, which may cause certain damage to its internal components and pose certain safety hazards to on-site workers.
