AI Technical Summary
The existing silicon powder push pipelines are prone to wear and leakage during transportation, especially under high temperature and high pressure conditions, which are difficult to deal with after leakage, which has safety problems. At the same time, the existing leak detection methods have reduced detection accuracy due to the existence of inner lining ceramics, making it difficult to detect and prevent leakage in a timely manner.
A push pipe structure is designed, including a push pipe, a first clamp, a second clamp and a detection assembly. The first clamping member and the second clamping clip are arranged on the pushing tube to form a clamping cavity, and the pushing tube is located in the clamping cavity. The detection component is slidably arranged on the first clamping member, and by detecting the pressure of the first clamping member, the pressure of the pushing pipe is determined, and whether a leakage occurs.
With this structure, the leakage of the push pipe can be facilitated and the reliability of the push pipe can be improved. Even if the material pushing pipe leaks, the substances in the material pushing pipe will not leak directly into the environment, thus achieving a certain leakage prevention effect.

Abstract

[0003] During the existing transportation of silicon powder, the pipeline will inevitably be worn, which is likely to cause leakage. Especially in the pusher pipeline from the silicon powder feeding tank to the reactor, the temperature and pressure are relatively high, and it is not easy to handle after leakage, resulting in safety problems. The wear condition of the pipeline is directly detected by a thickness gauge. In order to reduce wear, a ceramic lining is added inside the silicon powder pusher pipeline to enhance the pipeline strength and delay pipeline wear.

Since the ceramic lining is relatively thick and the material is different from the inner wall of the pipeline, the detection accuracy is reduced, making it difficult to detect and prevent leakage in a timely manner.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or can communicate with each other; it may be a direct connection, or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0044] Polysilicon is a form of elemental silicon. In the production process of polysilicon, it is necessary to use a dedicated silicon powder pusher pipeline feeder to push silicon powder into the processing equipment, and the silicon powder reacts in the processing equipment to obtain polysilicon.
[0045] During the existing transportation of silicon powder, the particle size and hardness of the silicon powder have a direct impact on the wear of the pipeline. Generally speaking, the finer the particle size and the higher the hardness, the more serious the wear on the inner wall of the pipeline, and it is easy to cause pipeline leakage. Especially in the silicon powder feeding tank and the silicon powder pusher pipeline entering the reactor section, the temperature and pressure are relatively high, and it is not easy to handle after leakage. And a large amount of leaked silicon powder accumulates in the external environment, which may cause an explosion and pose a safety problem.
[0046] Since pipelines are often made of metal materials, in order to prevent leakage, a thickness gauge is used to directly detect the wear of the pipeline to check for leakage and determine whether the pipeline can be used. The thickness gauge determines the thickness of the material to be measured by detecting the propagation time of the detection medium in the same material. The thickness gauge can be an ultrasonic thickness gauge or an electromagnetic thickness gauge.
[0047] In the prior art, in order to reduce wear, a ceramic lining is added inside the silicon powder pusher pipeline to enhance the pipeline strength and delay pipeline wear.
[0048] Since the thickness gauge determines the thickness of the material to be measured by detecting the propagation time of the detection medium in the same material, and the ceramic lining is relatively thick and the material is different from the inner wall of the pipeline, the accuracy of the detection is reduced, making it difficult to detect and prevent leakage in a timely manner.
[0049] In view of this, an embodiment of the present application provides a pusher tube structure, including: a pusher tube, a first clamping member, a second clamping member, and a detection assembly; the first clamping member and the second clamping member are clamped on the pusher tube, the first clamping member and the second clamping member enclose a clamping cavity, and the pusher tube is located in the clamping cavity; the detection assembly is slidably disposed on the first clamping member, driving the detection assembly to move relative to the surface of the first clamping member, and detecting the pressure of the first clamping member to detect the pressure of the pusher tube. The detection assembly moves relative to the surface of the first clamping member, detecting the pressure of the first clamping member to detect the pressure of the pusher tube, determining whether the pusher tube has leaked, thereby facilitating the pre-inspection of the leakage of the pusher tube, improving the reliability of the pusher tube, and moreover, by clamping the first clamping member and the second clamping member outside the pusher tube, even if the pusher tube leaks, substances inside the pusher tube, such as silicon powder, will not directly leak into the environment, thus playing a certain anti-leakage effect.
[0050] The following combines Figures 1 to 3 and specific embodiments to elaborate on the present application in detail. Figure 1 is a schematic structural diagram of the pusher tube structure provided by the embodiment of the present application; Figure 2 is Figure 1 the side view of the pusher tube structure in Figure 3 is Figure 1 the partial enlarged view of part A in
[0051] An embodiment of the present application provides a pusher tube structure, including: a pusher tube 100, a first clamping member 200, a second clamping member 300, and a detection assembly 400; the first clamping member 200 and the second clamping member 300 are clamped on the pusher tube 100, and the first clamping member 200 and the second clamping member 300 enclose a clamping cavity, and the pusher tube 100 is located in the clamping cavity; the detection assembly 400 is slidably arranged on the first clamping member 200, driving the detection assembly 400 to move relative to the surface of the first clamping member 200, and detecting the pressure of the pusher tube 100 by detecting the pressure of the first clamping member 200.
[0052] Specifically, the pusher tube 100 is used to push silicon powder into the processing equipment. It should be noted that when the pusher tube 100 leaks, the pressure at the leakage point will drop, resulting in uneven pressure around the point, and it is judged whether the pusher tube 100 leaks through the uneven pressure. For example, when the pusher tube 100 does not leak, the pressure of the pusher tube 100 is 0, and when it leaks, the pressure at the leakage point on the pusher tube 100 becomes 50 MPa.
[0053] The first clamping member 200 and the second clamping member 300 are clamped on the pusher tube 100 and are oppositely arranged. Exemplarily, the cross-section of the pusher tube 100 is circular, the first clamping member 200 is located above the second clamping member 300, and the cross-sections of the first clamping member 200 and the second clamping member 300 are both semi-circular, so that the cross-section of the clamping cavity jointly formed by the first clamping member 200 and the second clamping member 300 is circular and is adapted to the pusher tube 100.
[0054] It can be understood that when the pressure inside the pusher tube 100 changes, such as leakage, the pressure on the surface of the pusher tube 100 changes. Since the first clamping member 200 is in close contact with the pusher tube 100, the pressure change on the pusher tube 100 will be transmitted to the outer wall of the first clamping member 200. By detecting the pressure of the first clamping member 200, the pressure of the pusher tube 100 can be obtained.
[0055] The lower surface of the detection assembly 400 is attached to the upper surface of the first clamping member 200, so that the pressure of the pusher tube 100 can be obtained by detecting the pressure of the first clamping member 200. The detection assembly 400 is slidably arranged on the first clamping member 200 and slides along the extending direction of the first clamping member 200. The detection assembly 400 moves relative to the surface of the first clamping member 200, and performs pressure detection on the surfaces of the pusher tube 100 and the first clamping member 200, that is, moves along the length direction of the pusher tube 100, performs multi-point pressure detection on the pusher tube 100, so as to comprehensively detect whether the pusher tube 100 leaks, facilitate pre-checking the leakage situation, and thus improve the reliability of the pusher tube 100.
[0056] It should be noted that the first clamping member 200 and the second clamping member 300 are clamped outside the pusher tube 100. Even if the pusher tube 100 leaks, substances inside the pusher tube 100, such as silicon powder, will not directly leak into the environment, thus achieving a certain anti-leakage effect.
[0057] In the pusher tube structure of the embodiment of the present application, the first clamping member 200 and the second clamping member 300 are clamped outside the pusher tube 100. Even if the pusher tube 100 leaks, substances inside the pusher tube 100, such as silicon powder, will not directly leak into the environment, thus achieving a certain anti-leakage effect. The detection component 400 moves relative to the surface of the first clamping member 200 to detect the pressure on the surfaces of the pusher tube 100 and the first clamping member 200, facilitating pre-checking of leakage situations and improving the reliability of the pusher tube 100.
[0058] In some embodiments, for the pusher tube structure provided by the embodiment of the present application, the first clamping member 200 includes a first clamping tube 210 and two first side plates 220, and the two first side plates 220 are arranged on both sides of the first clamping tube 210; the second clamping member 300 includes a second clamping tube 310 and two second side plates 320, and the two second side plates 320 are arranged on both sides of the second clamping tube 310. The second clamping tube 310 is arranged opposite to the first clamping tube 210, the second clamping tube 310 and the first clamping tube 210 clamp the pusher tube 100, and the first side plates 220 are correspondingly connected to the second side plates 320.
[0059] Specifically, when implemented, two first side plates 220 are arranged on both sides of the first clamping tube 210, and the two first side plates 220 are arranged opposite to each other. Exemplarily, the first clamping tube 210 is semicircular, and the two first side plates 220 are arranged in parallel on both sides of the first clamping tube 210.
[0060] The second clamping tube 310 is arranged opposite to the first clamping tube 210, and the second clamping tube 310 and the first clamping tube 210 form a clamping cavity, and the pusher tube 100 is located in the clamping cavity. Exemplarily, the cross-section of the pusher tube 100 is circular, and the cross-sections of the second clamping tube 310 and the first clamping tube 210 are both semicircular, so that the cross-section of the clamping cavity formed by the second clamping tube 310 and the first clamping tube 210 together is circular and is adapted to the pusher tube 100. The second clamping tube 310 and the first clamping tube 210 provide a uniform clamping force for the pusher tube 100.
[0061] It should be noted that in the pusher tube structure of the embodiment of the present application, the first side plates 220 and the second side plates 320 facilitate the connection or disconnection of the second clamping tube 310 and the first clamping tube 210.
[0062] The embodiments of the present application do not limit the connection manner between the first side plate 220 and the second side plate 320. Exemplarily, threaded holes are provided on both the first side plate 220 and the second side plate 320, and bolts are connected to the threaded holes to threadedly connect the first side plate 220 and the second side plate 320. Alternatively, magnetic components are provided on the opposite sides of the first side plate 220 and the second side plate 320, and the first side plate 220 and the second side plate 320 are magnetically connected.
[0063] In addition, the first side plate 220 and the second side plate 320 can also be connected by a buckle. For example, on the side of the first side plate 220 facing the second side plate 320, a clamping plate 321 is provided. The clamping plate 321 is arranged along the extending direction of the first side plate 220. The length of the clamping plate 321 can be flush with the length of the first side plate 220, can be less than the length of the first side plate 220, or can be greater than the length of the first side plate 220. On the side of the second side plate 320 facing the first side plate 220, a clamping groove 221 adapted to the clamping plate 321 is provided. The clamping plate 321 is clamped with the clamping groove 221, so that the first side plate 220 and the second side plate 320 are closely attached, and the second clamping pipe 310 and the first clamping pipe 210 clamp the pushing pipe 100. The embodiments of the present application do not limit the specific structures and materials of the clamping plate 321 and the clamping groove 221. Exemplarily, the clamping plate 321 is in an inverted hook shape, and the material of the clamping plate can be plastic.
[0064] During use, by placing the semi-circular first clamping pipe 210 on the upper side of the pushing pipe 100, aligning the second clamping pipe 310 upward with both sides of the first clamping pipe 210, clamping the first side plate 220 on the lower side of the pushing pipe 100, aligning the clamping plate 321 with the clamping groove 221, and pressing and inserting forcefully, the inverted hook-shaped clamping plate 321 is deformed and clamped in the clamping groove 221, so that the first clamping pipe 210 and the second clamping pipe 310 can be clamped outside the pushing pipe 100. Even if the pipeline leaks, the material will not directly leak into the environment, achieving an efficient anti-leakage effect.
[0065] In some other embodiments, for the pushing pipe structure provided by the embodiments of the present application, the first clamping member 200 and the second clamping member 300 are detachably connected.
[0066] Specifically, the first clamping member 200 and the second clamping member 300 are oppositely arranged, and the clamping cavity formed by the first clamping member 200 and the second clamping member 300 is circular or quasi-circular. At least one end of the first clamping member 200 and the second clamping member 300 is detachably connected.
[0067] During use, the first clamping member 200 and the second clamping member 300 move relatively away from each other to open the clamping cavity, and the pushing tube 100 is placed into the clamping cavity. After the pushing tube 100 is placed into the clamping cavity, the first clamping member 200 and the second clamping member 300 move relatively closer to each other to close the clamping cavity and seal the pushing tube 100 within the clamping cavity. Since the first clamping member 200 and the second clamping member 300 are clamped outside the pushing tube 100, even if the pushing tube 100 leaks, substances within the pushing tube 100, such as silicon powder, will be temporarily stored within the clamping cavity, preventing direct leakage into the environment and causing safety issues.
[0068] It should be noted that the first clamping member 200 and the second clamping member 300 can be connected by threads or by snap connections. This application places no restrictions thereon.
[0069] In some possible implementation manners, for the pushing tube structure provided in the embodiments of the present application, a clamping groove 221 is provided on one of the first side plate 220 and the second side plate 320, and a clamping plate 321 is provided on the other of the first side plate 220 and the second side plate 320, and the clamping plate 321 is inserted into the clamping groove 221.
[0070] Specifically, a clamping groove 221 is provided on one of the first side plate 220 and the second side plate 320, and a clamping plate 321 is provided on the other of the first side plate 220 and the second side plate 320. The clamping groove 221 and the clamping plate 321 are adapted to each other.
[0071] Exemplarily, a clamping plate 321 is provided on the first side plate 220, and a clamping plate is provided on the second side plate 320. The clamping plate 321 is inserted into the clamping groove 221, thereby clamping the first side plate 220 and the second side plate 320.
[0072] In some optional implementation manners, for the pushing tube structure provided in the embodiments of the present application, the detection assembly 400 includes a moving member 410, a connecting member 420, and a detecting member 430. The moving member 410 is slidably disposed on the first clamping member 200. The detecting member 430 is connected to the moving member 410 through the connecting member 420, and the side of the detecting member 430 facing away from the connecting member 420 is adapted to the first clamping tube 210.
[0073] The moving member 410 is slidably disposed on the first clamping member 200. The connecting member 420 is connected to the moving member 410, and the moving member 410 drives the connecting member 420 to slide synchronously. The connecting member 420 is connected to the detecting member 430, and the detecting member 430 is in contact with the first clamping tube 210.
[0074] In some embodiments, the detecting member 430 is a pressure detector. Exemplarily, when the moving member 410 drives the detecting member 430 to move along the extending direction of the first clamping tube 210 to the front end portion of the first clamping tube 210, the pressure value displayed by the detecting member 430 is 0; when moving to the middle portion of the first clamping tube 210, the pressure value displayed by the detecting member 430 is 50 MPa; when moving to the rear end portion of the first clamping tube 210, the pressure value displayed by the detecting member 430 is 0. This indicates that there is a leakage in the middle portion of the first clamping tube 210, that is, there is a leakage in the pusher tube 100.
[0075] In some possible implementation manners, for the pusher tube structure provided in the embodiments of the present application, the moving member 410 includes a limiting groove 411, a screw 412, and a slider 413. The limiting groove 411 is provided on the first clamping member 200. The screw 412 is partially disposed in the limiting groove 411. The slider 413 is sleeved on the screw 412 and is slidably connected to the screw 412. The connecting member 420 is connected to the slider 413.
[0076] Specifically, the limiting groove 411 is provided on the first clamping member 200. The limiting groove 411 is arranged along the extending direction of the first clamping member 200, providing a moving range for the relative movement of the screw 412 and the slider 413.
[0077] A part of the screw 412 is in the limiting groove 411. The screw 412 is a rod-shaped part with a spiral. The slider 413 is sleeved on the screw 412. Since a thread groove or a threaded hole that matches the thread of the screw 412 is provided inside the slider 413, when the screw 412 rotates, due to the interaction between the thread and the thread groove or the threaded hole inside the slider 413, the rotational motion is converted into a linear motion, so that the slider 413 moves along the axial direction of the screw 412. In some embodiments, in order to improve the transmission efficiency and reduce friction, the contact surface between the slider 413 and the screw 412 can be provided with a special geometric shape, such as a spiral raceway and a ball.
[0078] In some embodiments, lubricating oil can also be added between the slider 413 and the screw 412 to reduce friction.
[0079] Among them, for the pusher tube structure provided in the embodiments of the present application, the moving member 410 further includes a knob 414. The knob 414 is arranged outside the first clamping member 200. One end of the screw 412 passes through the limiting groove 411 and is connected to the knob 414.
[0080] Specifically, in order to facilitate the adjustment of the movement of the moving member 410, the pusher tube structure in the embodiments of the present application further includes a knob 414. The knob 414 is connected to the screw 412. Exemplarily, the knob 414 is arranged outside the first clamping member 200. One end of the screw 412 passes through the limiting groove 411 and is connected to the knob 414.
[0081] Rotating the knob 414, the screw rod 412 and the slider 413 are similar to a lead screw drive, converting rotational motion into linear motion.
[0082] In some embodiments, the knob 414 can be manually driven to rotate, so that the slider 413 moves relative to the screw rod 412. The knob 414 is located outside the first clamping member 200, facilitating direct manual adjustment by the operator. The knob 414 can also be driven to rotate by a motor, so that the slider 413 moves relative to the screw rod 412.
[0083] In some embodiments, the knob 414 can also be provided with a rotation scale, so that the operator can intuitively adjust the position or distance.
[0084] In addition, for the pusher tube structure provided in the embodiments of the present application, the connecting member 420 includes an insertion plate 421 and a top ring 422. The top ring 422 is provided on the insertion plate 421. The top ring 422 is connected to the detection member 430, and the insertion plate 421 is inserted into the moving member 410.
[0085] Specifically, the connecting member 420 includes an insertion plate 421 and a top ring 422, and the top ring 422 is provided on the insertion plate 421. Exemplarily, the top ring 422 is integrally formed with the insertion plate 421 or the top ring 422 is welded to the insertion plate 421.
[0086] A detection member 430 is provided on the side of the top ring 422 facing the first clamping tube 210. The top ring 422 is used to make the detection member 430 disposed opposite to the first clamping tube 210, and the detection member 430 is used to measure the pressure of the first clamping tube 210.
[0087] The present application does not limit the specific shape of the top ring 422. Exemplarily, the top ring 422 can be arc-shaped.
