Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning the electrode magnetic ring of a polysilicon reduction furnace. BACKGROUND

[0002] In the production of polysilicon, a polysilicon reduction furnace synthesizes trichlorosilane from silicon tetrachloride, hydrogen and silicon powder at a certain temperature, and deposits polysilicon on a silicon core under the action of electricity and high temperature. In this process, the electrode magnetic ring will deposit a large amount of silicon powder attached to the magnetic ring, thereby reducing the insulation effect of the electrode and the base plate, causing the grounding to stop the furnace prematurely, affecting the service life of the equipment, and further causing the grounding to stop the furnace and affecting the production capacity, and increasing the cost of later equipment maintenance.

[0024] Example 1

[0025] This invention provides a cleaning system for electrode magnetic rings in a reduction furnace, such as... Figure 1 As shown, it includes: a barrel body 1, with a pneumatic wrench air box 2 welded to the top of the barrel body 1; a cleaning assembly is connected inside the barrel body 1; and the pneumatic wrench air box 2 is used to connect a pneumatic wrench. The pneumatic wrench is an existing pneumatic wrench; other brakes are insufficient.

[0026] Preferably, the cleaning component includes: a first brush 3, a second brush 4, and a third brush 5 arranged sequentially from top to bottom. The first brush 3 is used to clean the gap at the connection between the electrode and the magnetic ring, the second brush 4 extends into the groove of the magnetic ring, and the third brush 5 cleans the gap at the connection between the chassis and the magnetic ring.

[0027] Preferably, the barrel body 1 is a cylindrical steel barrel with a height of 150 mm and an internal diameter of 160 mm.

[0028] Preferably, brush 1 (3) has a width of 30mm and a height of 5mm; brush 2 (4) has a width of 35mm and a height of 5mm; and brush 3 (5) has a width of 30mm and a height of 5mm.

[0029] Preferably, brush 3 5 is installed at the bottom of the barrel 1, the height difference between brush 1 3 and brush 2 4 is 6mm, and the height difference between brush 2 4 and brush 3 5 is 8mm.

[0030] This invention changes the traditional method of manually brushing magnetic rings, improves work efficiency, reduces dust, improves product quality, reduces the impact of feeding on the electrodes of the reduction furnace, and increases the production efficiency of the reduction furnace.

[0031] The beneficial effects of the above technical solution are as follows: In this invention, three brushes are welded inside the barrel 1, from the inside out. Brush 1 (3) is welded 25mm inward from the bottom of the steel barrel to clean the gap between the electrode and the magnetic ring. Brush 2 (4) is 35mm wide, extending into the groove of the magnetic ring for better cleaning of deposited silicon. The height difference between brush 1 (3) and brush 2 (4) is 6mm. Brush 3 (5) is welded to the bottom of the steel barrel, parallel to the outer wall, to clean the gap between the base and the magnetic ring, thus increasing the creepage distance of the magnetic ring. The height difference between brush 2 (4) and brush 3 (5) is... 8mm; This invention changes the traditional method of manually brushing magnetic rings, improving work efficiency, reducing dust and improving product quality, reducing the impact of feeding on the electrodes of the reduction furnace, and improving the production efficiency of the reduction furnace; it reduces manual workload, increases speed, improves electrode operation stability, avoids grounding, increases creepage distance, protects the silver plating layer of the electrode, and reduces dust generated during the cleaning process; this invention can be operated by one person, shortening the cleaning time of four people by 1 / 4, the cleanliness of the magnetic ring can reach 70% of that of a new magnetic ring, abnormal grounding is reduced by 80%, and the dust generated is almost zero.

[0032] The present invention solves the problem mentioned in the background art: In the prior art, the cleaning of the electrode magnetic ring of the reduction furnace is usually done manually with a wire brush. The wire material of the traditional brush currently used is relatively soft, which leads to high manual labor intensity and relatively poor cleaning efficiency and effect.

[0033] Example 2

[0034] Based on Example 1, such as Figures 2-4 As shown, a multi-functional collection device 6 is also provided on the upper inner wall of the barrel 1. The multi-functional collection device 6 includes:

[0035] A fixed box 61 is fixedly installed on the upper wall inside the barrel 1. A dust collection box 65 is fixedly installed inside the fixed box 61. The lower end of the fixed box 61 is connected to a suction head 620. The upper part of the dust collection box 65 is connected to a suction pipe 62, which is connected to a negative pressure suction device. The upper part of the suction pipe 62 penetrates the upper wall of the barrel 1. A filter plate 64 is installed at the air inlet 63 at the lower end of the suction pipe 62. The dust collection box 65 is divided into a drive chamber and a filter chamber by a vertical plate 621. A collection trough 619 is installed at the lower end of the dust collection box 65, directly below the filter plate 64. A collection container is placed in the collection trough.

[0036] An electric telescopic rod 66 is fixed inside the drive cavity. The electric telescopic rod 66 is arranged in the left-right direction. The telescopic part of the electric telescopic rod 66 slides through the vertical plate 621 and is fixedly connected to the fixing block 69. A brush is provided at the upper end of the fixing block 69. A conical block 68 is fixed at the lower end of the telescopic part of the electric telescopic rod 66. The first conical surface at the lower end of the conical block 68 is lower on the left and higher on the right. An air blowing component is provided at the lower end of the conical block 68.

[0037] Preferably, the air blowing assembly includes:

[0038] A vertical moving rod 614 slides through the lower wall of the dust collector 65. The upper end of the vertical moving rod 614 contacts the first conical surface at the lower end of the conical block 68. A limiting block 615 is installed in the middle of the vertical moving rod 614. A second spring 617 is connected between the limiting block 615 and the inner wall of the dust collector 65. The lower end of the vertical moving rod 614 is located inside the air blowing box 616 and is fixedly connected to a piston plate 618. The piston plate 618 slides up and down inside the air blowing box 616. The air blowing box 616 is fixed to the lower wall of the dust collector 65. An air outlet nozzle is connected to the lower end of the air blowing box 616. A compressed gas storage box 622 is connected inside the fixed box 61. The air outlet of the compressed gas storage box 622 is connected to the air inlet of the piston plate 618 on the side wall of the air blowing box 616 through a pipe.

[0039] Preferably, a trapezoidal block 67 is fixed to the upper end of the telescopic portion of the electric telescopic rod 66. The upper end of the trapezoidal block 67 is provided with a second conical surface that is higher on the left and lower on the right. The trapezoidal block 67 is used to drive the striking assembly, which includes:

[0040] A fixing frame 610 is fixed to the lower end of the suction pipe 62. The fixing frame 610 is rotatably connected to a connecting rod 611 (the middle part of the connecting rod 611 is rotatably connected to the fixing frame 610 through a pivot in the front-back direction). The left end of the connecting rod 611 contacts the first conical surface of the trapezoidal block 67. The right end of the connecting rod 611 passes through the wall of the suction pipe 62 and is fitted with a hitting ball 612. A first spring 613 is provided in the middle of the connecting rod 611. The first spring 613 is installed between the middle of the connecting rod 611 and the lower end of the suction pipe 62.

[0041] The beneficial effects of the above technical solution are as follows:

[0042] (1) During operation, since the suction pipe 62 is connected to the negative pressure suction device, the dust-laden gas enters the filter chamber from the suction head 620, and then the air filtered by the filter plate 64 enters the suction pipe 62 and is discharged. During this period, large dust particles filtered by the filter plate 64 will fall into the collection container in the collection tank 619, which is convenient for staff to clean and recycle.

[0043] (2) During the filtration process of filter plate 64, the electric telescopic rod 66 is driven. Since the telescopic part of the electric telescopic rod 66 slides through the vertical plate 621 and is connected to the fixed block 69, and the fixed block 69 is equipped with a brush, the telescopic part of the electric telescopic rod 66 will clean the dust on the filter plate 64 when it is working, so as to prevent too much dust from clogging the filter plate 64.

[0044] (3) When the electric telescopic rod 66 is in operation, since a trapezoidal block 67 is fixed to the upper end of the telescopic part of the electric telescopic rod 66, and the upper end of the trapezoidal block 67 is provided with a second conical surface that is higher on the left and lower on the right, the electric telescopic rod 66 will drive the connecting rod 611 (e.g.) when it moves. Figure 3 As shown, it is an inverted V-shaped structure, so that the striking ball 612 connected to the connecting rod 611 strikes the filter plate 64, which will knock the impurities in the filter plate 64 into the collection groove 619, effectively preventing the filter plate 64 from clogging.

[0045] (4) When the electric telescopic rod 66 is working, since the lower end of the telescopic part of the electric telescopic rod 66 is fixed with a conical block 68, and the first conical surface of the lower end of the conical block 68 is lower on the left and higher on the right, the electric telescopic rod 66 will drive the moving rod 614 when it moves. The moving rod 614 moves up and down, causing the piston plate 618 to move up and down in the air blowing box 616. Since the lower end of the air blowing box 616 is connected to the air outlet nozzle, and the fixed box 61 is connected to the compressed gas storage box 622, the air outlet of the compressed gas storage box 622 is connected to the air inlet of the piston plate 618 on the side wall of the air blowing box 616 through a pipe, the dust in the barrel 1 will be blown up, which facilitates the dust suction head 620 to suction the dust. The multi-functional collection device 6 removes dust more cleanly and improves work efficiency. Moreover, when the present invention removes dust, the dust is automatically discharged after being collected in the barrel 1, avoiding splashing.

[0046] This invention reduces manual labor and thus improves efficiency, reduces dust generated during the cleaning process, and greatly improves cleaning efficiency.

[0047] Example 3

[0048] Based on Examples 1 and 2, brush one 3, brush two 4, and brush three 5 all include a brush rod, and a detachable bristle sleeve is provided on the outside of the brush rod. The reduction furnace electrode magnetic ring cleaning system also includes:

[0049] A pneumatic wrench mounting plate is provided, which is perpendicular to the pneumatic wrench sleeve 2. The pneumatic wrench is mounted on the pneumatic wrench mounting plate via a telescopic rod coaxial with the pneumatic wrench sleeve 2. Several distance sensors are provided at intervals on the outer periphery of the barrel 1. The distance sensors are used to detect the actual vertical distance between the barrel 1 and the pneumatic wrench mounting plate.

[0050] An angle detection device is used to detect the actual angle between the pneumatic wrench mounting plate and the horizontal plane;

[0051] The force measuring group consists of brush 1 (3), brush 2 (4), and brush 3 (5), each corresponding to a force measuring group. The force measuring group includes several force sensors, which are set at key force detection points on the brush handle. These key force detection points include key force points that ensure cleaning power and key force points that monitor damage to the electrode magnetic ring.

[0052] The memory stores the standard detection angle value of the angle detection device, the standard range of the detection value of the force sensor, and the first standard extension distance of the telescopic rod when cleaning the electrode magnetic rings of different types of reduction furnaces.

[0053] The control device is electrically connected to the distance sensor, angle detection device, memory, force measuring group, first alarm device, second alarm device, and pneumatic wrench. The control device controls the pneumatic wrench and the first and second alarm devices based on the distance sensor, angle detection device, memory, and force measuring group.

[0054] Preferably, the control device controls the pneumatic wrench and the first and second alarm devices based on a distance sensor, an angle detection device, a memory, and a force measuring group, including:

[0055] Step S1: Install the pneumatic wrench mounting plate inside the reduction furnace, then connect the pneumatic wrench to the pneumatic wrench sleeve. The control device controls the telescopic rod to extend the first standard telescopic distance, and then controls the distance sensor to detect. Based on the distance sensor and the angle detection device, the first position deviation is calculated. When the first position deviation is greater than or equal to the corresponding deviation threshold, the first alarm device alarms, reminding the user to adjust the position of the corresponding component in the cleaning system until the adjusted first position deviation is less than the corresponding deviation threshold.

[0056]

[0057] W represents the first position deviation, θ1 represents the actual detection value of the angle detection device, θ2 represents the standard detection angle value of the angle detection device, θ0 represents the first reference difference corresponding to θ1-θ2, and σ1 represents the evaluation weight corresponding to the first reference difference (with a value greater than 0 and less than 1); H i Let H0 be the value detected by the i-th distance sensor, where max represents the maximum value, min represents the minimum value, and H0 is the maximum value (H... i)-min(H i The maximum allowable second benchmark difference is σ2, which is the corresponding evaluation weight (with a value greater than 0 and less than 1).

[0058] Step S2: When the first position deviation is less than the corresponding deviation threshold, the control device controls the pneumatic wrench to drive the pneumatic wrench sleeve to rotate one revolution at the first speed to perform a rotation detection, and controls the force sensor to work in real time. When the force sensor detection value at the key force point is not within the standard range of the corresponding force sensor detection value (corresponding to the first speed), the control device controls the second alarm device to sound an alarm, reminding the user to adjust the position of the corresponding brush sleeve and replace the brush sleeve, until the force sensor detection value at the key force point is within the standard range of the corresponding force sensor detection value.

[0059] Step S3: Calculate the contact assessment value and cleaning force assessment value when the force sensor detection value at the key force points is qualified;

[0060]

[0061]

[0062] Q1 is the contact assessment value, Q2 is the cleaning power assessment value, M is the total number of critical stress points for damage monitoring of the electrode magnetic ring; N is the total number of critical stress points to ensure cleaning power; F j1 Fj is the actual detected value of the j-th critical stress point for damage monitoring of the electrode magnetic ring; F0 is the preset maximum allowable contact force; f ... k f0 represents the actual measured value of the k-th key force point that ensures cleaning effectiveness; f0 represents the preset target cleaning effectiveness; max represents the maximum value.

[0063] Step S4: Based on the contact evaluation value and cleaning force evaluation value when the force sensor detection value at the force point is qualified, calculate the target speed of the pneumatic wrench barrel. The control device controls the pneumatic wrench to work so that the actual speed of the pneumatic wrench barrel is the target speed of the pneumatic wrench barrel.

[0064]

[0065] n is the target rotational speed of the pneumatic wrench sleeve; n0 is the first rotational speed; F is the ideal cleaning force of the brush (a preset value that ensures cleaning effect while reducing damage to the electrode magnetic ring); ln is the natural logarithm; e is the natural constant; and K1 is the adjustment coefficient (with a value greater than 0 and less than 1).

[0066] The beneficial effects of the above technical solution are as follows:

[0067] 1. Install the pneumatic wrench mounting plate inside the reduction furnace, and then connect the pneumatic wrench to the pneumatic wrench sleeve. A mounting surface for the pneumatic wrench mounting plate can be provided within the reduction furnace, and the mounting surface can be detachably connected to the pneumatic wrench mounting plate (using a suction cup or snap-fit). By providing the pneumatic wrench mounting plate, the internal cleaning of the reduction furnace can be prevented from being easily damaged due to hand misalignment when holding the pneumatic wrench.

[0068] 2. Calculate the first position deviation based on the distance sensor and angle detection device; that is, before the pneumatic wrench is started, the installation position of the pneumatic wrench mounting plate and the position of the barrel are detected to ensure that the position of the pneumatic wrench mounting plate and the barrel is accurate, so as to ensure the cleaning effect and reduce damage to the internal components of the reduction furnace.

[0069] 3. The installation position of the pneumatic wrench mounting plate and the position of the barrel are accurately detected. At the beginning, a cleaning test is carried out at a low initial speed to determine the cleaning force during the cleaning test. This avoids damage caused by starting at high speed. Then, based on the force distribution at key stress points during the low-speed test, preliminary adjustments are made to ensure that the cleaning force is qualified at key stress points before high-speed testing. This ensures the cleaning force is qualified and the force at key stress points for monitoring the damage of the electrode magnetic ring is qualified to avoid damage to the device at high speed.

[0070] Then, based on the contact assessment value and cleaning force assessment value when the force distribution at the key stress points is qualified, as well as the actual first position deviation, a suitable cleaning speed is determined to ensure the cleaning effect while reducing damage to the internal components of the reduction furnace.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

Based on the distance sensor and the angle detection device, the first position deviation is calculated. When the first position deviation is greater than or equal to the corresponding deviation threshold, the first alarm device alarms, reminding the user to adjust the position of the corresponding component in the cleaning system until the adjusted first position deviation is less than the corresponding deviation threshold. Step S2: When the first position deviation is less than the corresponding deviation threshold, the control device controls the pneumatic wrench to drive the pneumatic wrench sleeve to rotate one revolution at the first speed to perform a rotation detection, and controls the force sensor to work in real time. When the force sensor detection value at the key force point is not within the standard range of the corresponding force sensor detection value, the control device controls the second alarm device to sound an alarm, reminding the user to adjust the position of the corresponding brush sleeve and replace the brush sleeve until the force sensor detection value at the key force point is within the standard range of the corresponding force sensor detection value. Step S3: Calculate the contact assessment value and cleaning force assessment value when the force sensor detection value at the key force points is qualified; Q1=[max(F j )+∑ M j=1 F j / M] / 2MF0 Q2=[max(f k )+∑ N k=1 f k / N] / 2Nf0; Q1 is the contact assessment value, Q2 is the cleaning power assessment value, M is the total number of critical stress points for damage monitoring of the electrode magnetic ring; N is the total number of critical stress points to ensure cleaning power; F j Fj is the actual detected value of the j-th critical stress point for damage monitoring of the electrode magnetic ring; F0 is the preset maximum allowable contact force; f ... k f0 represents the actual measured value of the k-th key force point that ensures cleaning effectiveness; f0 represents the preset target cleaning effectiveness; max represents the maximum value. Step S4: Based on the contact evaluation value and cleaning force evaluation value when the force sensor detection value at the key force point is qualified, calculate the target rotation speed of the pneumatic wrench barrel. The control device controls the pneumatic wrench to work so that the actual rotation speed of the pneumatic wrench barrel is the target rotation speed of the pneumatic wrench barrel.
