Detailed implementation manners

[0023] In order to enable the personnel in the art to better understand the solution of this application, the technical solutions in the specific implementation manners of this application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of this application.

[0024] As Figure 1 shown, a single crystal furnace cleaning device 100 is provided. The single crystal furnace cleaning device 100 is used to clean the carbon-carbon heat preservation barrel 200. Specifically, compounds adhere to the inner wall of the carbon-carbon heat preservation barrel 200. Therefore, this application uses the single crystal furnace cleaning device 100 to clean and polish the compounds adhering to the inner wall of the carbon-carbon heat preservation barrel 200, thereby improving the processing speed of the carbon-carbon heat preservation barrel 200 and further improving the working efficiency of the single crystal furnace cleaning device 100. To clearly illustrate the technical solution of the application, the front, rear, left, right, up, and down as Figure 1 shown are also defined. In this application, the length direction of the single crystal furnace cleaning device 100 refers to the above-mentioned front-rear direction, the width direction of the single crystal furnace cleaning device 100 refers to the above-mentioned left-right direction, and the vertical direction refers to the above-mentioned up-down direction.

[0025] As Figure 1 and Figure 2As shown, as an implementation, the single crystal furnace cleaning device 100 includes a housing 11, a plurality of positioning components 12, and a cleaning component 13. The housing 11 serves as the basic framework of the single crystal furnace cleaning device 100 and is used to support the plurality of positioning components 12 and the cleaning component 13. Among them, an accommodation cavity 101 is formed around the housing 11, and the carbon-carbon heat preservation barrel 200 is located above the housing 11 and is carried by the housing 11 to improve the stability of the carbon-carbon heat preservation barrel 200. Further, the plurality of positioning components 12 are located above the housing 11 and are connected to the housing 11. A limiting space 102 for accommodating the carbon-carbon heat preservation barrel 200 is formed around the plurality of positioning components 12. When the carbon-carbon heat preservation barrel 200 is installed in the limiting space 102, the plurality of positioning components 12 surround and abut against the outer wall of the carbon-carbon heat preservation barrel 200 to prevent the carbon-carbon heat preservation barrel 200 from sliding relative to the housing 11, thereby realizing the limitation of the carbon-carbon heat preservation barrel 200. Specifically, at least a part of the cleaning component 13 is located in the limiting space 102 and is supported by the housing 11. The cleaning component 13 includes a cleaning member 131 located in the limiting space 102. The cleaning member 131 has a rotational degree of freedom so that the cleaning member 131 can clean the carbon-carbon heat preservation barrel 200. More specifically, the cleaning member 131 can rotate in the limiting space 102. When the carbon-carbon heat preservation barrel 200 is installed in the limiting space 102, at least a part of the cleaning member 131 abuts against the inner wall of the carbon-carbon heat preservation barrel 200 and rotates relative to the carbon-carbon heat preservation barrel 200, so that the cleaning component 13 can clean and polish the compounds attached to the inner wall of the carbon-carbon heat preservation barrel 200. Through the above settings, the components of the single crystal furnace cleaning device 100 cooperate with each other and have a fast response speed. The cleaning ability of the cleaning member 131 is relatively high and the cleaning speed is relatively fast, which is beneficial to improving the cleaning speed of the carbon-carbon heat preservation barrel 200, and further beneficial to improving the cleaning efficiency of the single crystal furnace cleaning device 100.

[0026] As Figure 2 and Figure 3As shown, in this embodiment, the cleaning assembly 13 further includes a driving mechanism 132. The driving mechanism 132 is at least partially located inside the housing 11 and supported by the housing 11. The driving end of the driving mechanism 132 has a rotational degree of freedom, and the driving end of the driving mechanism 132 can drive the cleaning member 131 to rotate. Specifically, the driving mechanism 132 has a rotational function. The driving mechanism 132 is located inside the accommodation cavity 101, and the cleaning member 131 is located above the driving mechanism 132 and connected to the driving mechanism 132. When the carbon-carbon heat preservation barrel 200 is installed in the limiting space 102, the cleaning member 131 is located inside the carbon-carbon heat preservation barrel 200 and at least partially abuts against the inner wall of the carbon-carbon heat preservation barrel 200, and the driving mechanism 132 drives the cleaning member 131 to rotate. More specifically, when the carbon-carbon heat preservation barrel 200 is sleeved on the cleaning member 131, the plurality of positioning components 12 move together in the direction close to the carbon-carbon heat preservation barrel 200 to fix the carbon-carbon heat preservation barrel 200 on the housing 11. Then, the cleaning member 131 moves in the direction close to the inner wall of the carbon-carbon heat preservation barrel 200 and abuts against the inner wall of the carbon-carbon heat preservation barrel 200. The driving mechanism 132 starts to rotate and drives the cleaning member 131 to rotate, so as to clean and polish the compounds attached to the inner wall of the carbon-carbon heat preservation barrel 200. Through the above settings, the cleaning speed of the carbon-carbon heat preservation barrel 200 can be improved, which is beneficial to improving the working efficiency of the single crystal furnace cleaning device 100.

[0027] As Figure 3 shown, as an implementation manner, the cleaning assembly 13 further includes a fixed base 133 and a sliding bracket 134. The fixed base 133 is fixedly connected to the driving end of the driving mechanism 132, so that the driving mechanism 132 can drive the fixed base 133 to rotate. The sliding bracket 134 is slidably connected to the fixed base 133, and the cleaning member 131 is rotatably connected to the sliding bracket 134. Specifically, the fixed base 133 is located above the driving mechanism 132 and fixedly connected to the driving mechanism 132. The sliding bracket 134 is located above the fixed base 133 and slidably connected to the fixed base 133. The cleaning member 131 extends substantially in the vertical direction. When the carbon-carbon heat preservation barrel 200 is installed in the limiting space 102, the cleaning member 131 can abut against the inner wall of the carbon-carbon heat preservation barrel 200. Through the above settings, the sliding bracket 134 can adjust the position of the cleaning member 131 to make the cleaning member 131 adapt to carbon-carbon heat preservation barrels 200 of different specifications, and the cleaning member 131 can rotate with the driving mechanism 132 and polish the inner wall of the carbon-carbon heat preservation barrel 200, which is beneficial to improving the compatibility of the cleaning assembly 13 and further beneficial to improving the cleaning efficiency of the cleaning assembly 13.

[0028] In this embodiment, the cleaning assembly 13 further includes a bracket driving member 135 and a cleaning driving member 136. The bracket driving member 135 is fixedly connected to the fixed base 133. The bracket driving member 135 is in transmission connection with the sliding bracket 134. The bracket driving member 135 can drive the sliding bracket 134 to slide relative to the fixed base 133. Specifically, the fixed base 133 is used to support the bracket driving member 135, the sliding bracket 134 and the cleaning member 131. The bracket driving member 135 has a telescopic function. The bracket driving member 135 is connected to both the fixed base 133 and the sliding bracket 134 at the same time. The bracket driving member 135 drives the sliding bracket 134 to move, so that the sliding bracket 134 drives the cleaning member 131 to move. Through the above settings, when the carbon-carbon heat preservation barrel 200 is installed in the limiting space 102, the bracket driving member 135 can quickly drive the cleaning member 131 to move, so that the cleaning member 131 can quickly contact the inner wall of the carbon-carbon heat preservation barrel 200, which is beneficial to improving the cleaning speed of the cleaning assembly 13. At the same time, when the carbon-carbon heat preservation barrel 200 is cleaned, the bracket driving member 135 drives the cleaning member 131 to separate from the inner wall of the carbon-carbon heat preservation barrel 200, facilitating the replacement of the carbon-carbon heat preservation barrel 200, and further being beneficial to improving the assembly efficiency of the carbon-carbon heat preservation barrel 200.

[0029] More specifically, the cleaning driving member 136 is fixedly connected to the sliding bracket 134. The cleaning driving member 136 is in transmission connection with the cleaning member 131. The cleaning driving member 136 can drive the cleaning member 131 to rotate relative to the sliding bracket 134. Specifically, the cleaning driving member 136 can be located above or below the sliding bracket 134. The cleaning driving member 136 has a rotating function, so that the cleaning member 131 can rotate synchronously with the cleaning driving member 136. Through the above settings, the cleaning driving member 136 can increase the rotating speed of the cleaning member 131, so that the cleaning member 131 can quickly process the compound, which is beneficial to improving the working speed of the cleaning assembly 13, and further improving the working efficiency of the cleaning assembly 13.

[0030] In this embodiment, the cleaning assembly 13 further includes a fixing bracket 137 and a rotating roller 138. The fixing bracket 137 is connected to the sliding bracket 134, and the rotating roller 138 extends substantially in the vertical direction and is rotatably connected to the fixing bracket 137. Specifically, the rotating roller 138 has a rotating function. The rotating roller 138 is disposed close to the cleaning member 131. When the sliding bracket 134 moves toward the inner wall of the carbon-carbon heat preservation barrel 200, the rotating roller 138 abuts against the inner wall of the carbon-carbon heat preservation barrel 200. At this time, the bracket driving member 135 stops working, and the driving mechanism 132 starts to rotate so that the rotating roller 138 rotates around the inner wall of the carbon-carbon heat preservation barrel 200. Through the above arrangement, the rotating roller 138 can prevent the feeding amount of the cleaning member 131 from being too large, resulting in interference between the cleaning member 131 and the inner wall of the carbon-carbon heat preservation barrel 200, so as to prevent damage to the cleaning member 131 and / or the carbon-carbon heat preservation barrel 200, thereby being beneficial to improving the service life of the cleaning assembly 13 and / or the carbon-carbon heat preservation barrel 200. It should be noted that the cleaning member 131 and the rotating roller 138 can be made of polyurethane material, nylon material, etc., which is also beneficial to protecting the carbon-carbon heat preservation barrel 200.

[0031] Exemplarily, two rotating rollers 138 are provided, and the two rotating rollers 138 are respectively located on both sides of the cleaning member 131. Specifically, a plurality of cleaning members 131 can be provided, and each cleaning member 131 is at least equipped with two rotating rollers 138. In this application, the rotating rollers 138 are distributed on both sides of the sliding bracket 134 and the cleaning member 131, so that the forces on both sides of the sliding bracket 134 and the cleaning member 131 are balanced, avoiding offset of the cleaning member 131 or the sliding bracket 134 due to unbalanced force, and preventing interference between the cleaning member 131 and the carbon-carbon heat preservation barrel 200. Through the above arrangement, the stability of the cleaning member 131 during operation can be improved, which is further beneficial to improving the service life of the cleaning member 131 and / or the carbon-carbon heat preservation barrel 200.

[0032] As an implementation, the sliding bracket 134 includes an upper connecting plate 1341, a bracket plate 1342, and a lower connecting plate 1343. The lower connecting plate 1343 is slidably connected to the fixed base 133. The upper connecting plate 1341 and the lower connecting plate 1343 are distributed in the vertical direction and connected by the bracket plate 1342. Both ends of the cleaning member 131 are rotatably connected to the upper connecting plate 1341 and the lower connecting plate 1343 respectively. The fixed bracket 137 is connected to the upper connecting plate 1341. Both ends of the rotating roller 138 are rotatably connected to the fixed bracket 137 and the lower connecting plate 1343 respectively. Specifically, the lower connecting plate 1343 is formed by splicing multiple plates. The cleaning driving member 136 is located above the upper connecting plate 1341, and the cleaning member 131 is located between the upper connecting plate 1341 and the lower connecting plate 1343. More specifically, the upper connecting plate 1341 includes an upper rotating portion 1341a, the lower connecting plate 1343 includes a lower rotating portion 1343a and a lower limiting portion 1343b, and the fixed bracket 137 includes a bracket rotating portion 1371. The upper side of the cleaning member 131 is rotatably connected to the upper rotating portion 1341a, the lower side of the cleaning member 131 is connected to the lower rotating portion 1343a, the upper side of the rotating roller 138 is rotatably connected to the bracket rotating portion 1371, the lower side of the rotating roller 138 is connected to the lower limiting portion 1343b, and the cleaning driving member 136 is connected to the upper side of the upper rotating portion 1341a. Through the above settings, the assembly stability of the cleaning member 131 and the rotating roller 138 can be improved, and the structures of the cleaning member 131 and the rotating roller 138 are more compact, which is further beneficial to improving the structural compactness of the cleaning assembly 13.

[0033] In this embodiment, the lower connecting plate 1343 extends at least partially in the vertical direction to form a first connecting portion 1344, the fixed base 133 extends at least partially in the vertical direction to form a second connecting portion 1345 and a third connecting portion 1346, the bracket driving member 135 includes a propulsion base 1351 and a propulsion shaft 1352 slidably connected to the propulsion base 1351. The propulsion base 1351 is connected to the second connecting portion 1345 and the third connecting portion 1346, and one end of the propulsion shaft 1352 away from the propulsion base 1351 is connected to the first connecting portion 1344. Specifically, the propulsion shaft 1352 can slide within the propulsion base 1351. One end of the propulsion base 1351 is connected to the second connecting portion 1345, and the other end of the propulsion base 1351 is connected to the third connecting portion 1346. When the propulsion shaft 1352 moves relative to the propulsion base 1351, the propulsion shaft 1352 can drive the first connecting portion 1344 to move, so that the lower connecting plate 1343 drives the rotating roller 138 and the cleaning member 131 to move. Through the above arrangement, the connection strength between the propulsion base 1351 and the fixed base 133 can be improved, and the volumes of the first connecting portion 1344, the second connecting portion 1345 and the third connecting portion 1346 are relatively small, thus avoiding the first connecting portion 1344, the second connecting portion 1345 and the third connecting portion 1346 occupying a large space, and further being beneficial to improving the space utilization rate of the single crystal furnace cleaning device 100.

[0034] Exemplarily, the cleaning assembly 13 includes a slideway 139 and a slider 140 slidably connected to the slideway 139. The slideway 139 is fixedly connected to the fixed base 133, and the slider 140 is fixedly connected to the sliding bracket 134. Specifically, the slideway 139 is located on the upper side of the fixed base 133, the slider 140 is basically located on the lower side of the sliding bracket 134, and the sliding direction of the slider 140 is the same as the movement direction of the propulsion shaft 1352. Through the above arrangement, the connection strength between the slider 140 and the slideway 139 is relatively high, which is beneficial to improving the structural stability of the cleaning assembly 13. At the same time, the bracket driving member 135 is arranged close to the slider 140 and the slideway 139, so that the structure among the three is more compact, and further is beneficial to improving the structural compactness of the cleaning assembly 13.

[0035] Such as Figure 4As shown, as an implementation, the positioning component 12 includes a positioning base 121, a positioning driving member 122, and a positioning sliding plate 123.

The positioning driving member 122 is fixedly connected to the positioning base 121, and the positioning driving member 122 and the positioning sliding plate 123 are in transmission connection. The positioning driving member 122 can drive the positioning sliding plate 123 to slide relative to the positioning base 121. Specifically, both ends of the positioning driving member 122 are respectively connected to the positioning base 121 and the positioning sliding plate 123, and the positioning sliding plate 123 abuts against or separates from the carbon-carbon heat-insulating barrel 200. The positioning driving member 122 is fixedly connected to the positioning base 121, the positioning driving member 122 has a telescopic function, and the telescopic part of the positioning driving member 122 is connected to the positioning sliding plate 123. When the positioning driving member 122 starts to work, the positioning driving member 122 can push the positioning sliding plate 123 to slide on the positioning base 121 so that the positioning sliding plate 123 can abut against the outer wall of the carbon-carbon heat-insulating barrel 200. Through the above settings, the positioning component 12 can clamp carbon-carbon heat-insulating barrels 200 of different specifications, which is beneficial to improving the compatibility of the positioning component 12. In addition, at least two groups of positioning components 12 are provided. When two groups of positioning components 12 are provided, the two groups of positioning components 12 are arranged oppositely. When more than three groups of positioning components 12 are provided, the positioning components 12 are evenly arranged around the circumference of the carbon-carbon heat-insulating barrel 200, so that the force on the carbon-carbon heat-insulating barrel 200 is balanced to prevent the carbon-carbon heat-insulating barrel 200 from being damaged, and it is also beneficial to improve the service life of the carbon-carbon heat-insulating barrel 200.

[0036] In this embodiment, the positioning component 12 further includes a positioning boss seat 124 connected to the positioning sliding plate 123. The positioning boss seat 124 is located on the side of the positioning sliding plate 123 close to the limiting space 102. The end face of the positioning boss seat 124 close to the limiting space 102 is an arc surface, and the arc surface is used to fit with the outer wall of the carbon-carbon heat-insulating barrel 200. Specifically, since the outer wall of the carbon-carbon heat-insulating barrel 200 is an arc surface, the contact surface between the positioning boss seat 124 and the carbon-carbon heat-insulating barrel 200 in this application is set as an arc surface, which is beneficial to improving the fit degree between the positioning boss seat 124 and the carbon-carbon heat-insulating barrel 200 to avoid the carbon-carbon heat-insulating barrel 200 from sliding, and it is also beneficial to improve the working stability of the positioning component 12.

[0037] As Figure 2 and Figure 5As shown, as an implementation, the driving mechanism 132 includes a rotating disk 1321 and a rotating member 1322 for driving the rotation of the rotating disk 1321. The housing 11 includes a rotating disk limiting hole 111. A plurality of cleaning members 131 are circumferentially distributed around the rotating disk 1321 and are connected to the rotating disk 1321. The rotating disk 1321 is located within the rotating disk limiting hole 111 and rotates relative to the rotating disk limiting hole 111. Specifically, the rotating disk 1321 is used to carry the cleaning members 131 and drive the cleaning members 131 to rotate. The limiting space 102 communicates with the accommodating cavity 101 through the rotating disk limiting hole 111, and the upper end surface of the rotating disk 1321 is substantially on the same horizontal plane as the upper end surface of the housing 11, so that the rotating disk 1321 is substantially located within the rotating disk limiting hole 111. Through the above settings, the working stability of the cleaning assembly 13 can be improved, and interference between the rotating disk 1321 and the housing 11 can be avoided, which is beneficial to improving the working stability of the driving mechanism 132. At the same time, the rotating disk 1321 occupies a small space, which is also beneficial to improving the space utilization rate of the single crystal furnace cleaning device 100.

[0038] It should be noted that the positioning driving member 122, the rotating member 1322, the bracket driving member 135, and the cleaning driving member 136 can all be set as power devices such as pneumatic motors or hydraulic motors to achieve the normal operation of the single crystal furnace cleaning device 100. Among them, in this application, a pneumatic motor is taken as an example for illustration. Since the pneumatic motor is driven by air pressure, the internal parts of the pneumatic motor can avoid reacting with compounds, which is beneficial to extending the service life of the single crystal furnace cleaning device 100.
