Abstract
Description
A water-quenched pure water tank silicon material lifting and cleaning device Technical Field
[0001] This patent relates to the field of silicon rod production technology, specifically a water-quenched pure water tank silicon material lifting and cleaning device. Background Technology
[0002] Silicon rods are rod-shaped materials made of high-purity polycrystalline or monocrystalline silicon, and they have extremely important applications in many fields such as semiconductors and photovoltaics. They are usually grown from high-purity polycrystalline silicon using processes such as the Czochralski method or the zone melting method.
[0003] Silicon rods are heated to approximately 450°C using a water quenching device. A robotic arm then transfers the silicon rods into a water-quenching pure water tank for rapid cooling. During this cooling process, stress is released, and silicon material may burst and fall out within the tank. Based on a 24-hour continuous production schedule, approximately 96 kg / day of silicon material remains in the pure water tank, affecting the robotic arm's operation and potentially causing malfunctions. Cleaning the silicon material from the water-quenching pure water tank requires draining the pure water, wasting approximately 4 m³ of pure water per cleaning. Based on production needs, this cleaning must be done daily, and the water quenching equipment must be shut down for approximately 1 hour during cleaning, impacting production efficiency. (Patent content)
[0004] The purpose of this patent is to provide a water-quenched pure water tank silicon material lifting and cleaning device to improve production efficiency and reduce maintenance costs.
[0005] To achieve the above objectives, this patent provides the following technical solution: a water-quenched pure water tank silicon material lifting and cleaning device, comprising a pure water tank, support legs uniformly fixedly installed at the bottom of the pure water tank, a controller provided on the front of the pure water tank, and lifting and cleaning components provided on the outside of the pure water tank.
[0006] Preferably, the lifting and cleaning assembly includes: a cleaning component disposed inside the pure water tank; and a driving component disposed outside the pure water tank.
[0007] Preferably, the cleaning component includes: a supporting base plate, which is fixedly installed on both sides of the outer wall of the pure water tank; and a connecting frame, which is movably disposed inside the pure water tank.
[0008] Preferably, a guide rod is symmetrically fixedly installed on the top of the support base plate, a limiting square plate is fixedly installed on the top of the guide rod, a movable plate is slidably sleeved on the outer wall of the guide rod, a connecting block is fixedly installed between the movable plates, a toothed chain is fixedly installed on the top of the connecting block, a connecting plate is fixedly installed on the other end of the toothed chain, a locking block is fixedly installed on the bottom of the connecting plate, a movable groove is symmetrically opened on one side of the locking block, and a guide rod is fixedly installed on the locking block through the movable groove.
[0009] The guide rod provides a stable and precise linear motion trajectory for the movable plate. When the drive component operates and drives the gear chain, the movable plate can move strictly up and down in a straight line along the guide rod, avoiding instability such as deviation or swaying during the movement.
[0010] Preferably, the outer wall of the guide rod is slidably fitted with a second locking block, and the outer wall of the guide rod is fitted with a spring. One end of the spring is fixedly connected to a first locking block, and the other end of the spring is fixedly connected to a second locking block. The first locking block is slidably connected to the second locking block through a movable groove. The inside of the connecting frame is provided with a grid plate, and the top of the grid plate is provided with a polyurethane screen. The top of the connecting frame is symmetrically provided with locking grooves. The connecting frame is locked to the first locking block through the locking grooves. The outer walls of the connecting frame are symmetrically provided with locking holes, which are connected to the locking grooves and are adapted to the second locking block.
[0011] Under the action of the spring, the second locking block can automatically lock and unlock with the locking hole of the connecting frame. When installing the connecting frame, the first locking block is inserted into the locking groove of the connecting frame, and the second locking block will smoothly lock into the locking hole under the push of the spring, completing the quick connection between the connecting frame and the transmission structure of the cleaning component. No additional complex fixing devices or a lot of installation operations are required, which improves the efficiency of equipment assembly.
[0012] Preferably, the driving component includes: a short shaft symmetrically and movably disposed on the front of the pure water tank; a motor fixedly mounted on the front of the pure water tank; and U-shaped fixing plates fixedly mounted on both sides of the outer wall of the pure water tank.
[0013] Preferably, the second pulley is connected to the first pulley via a belt drive. The outer wall of the short shaft is respectively fixedly fitted with a first gear and a first pulley. The first gear is located between the first pulley and the pure water tank, and the first gears are meshed together. The output end of the motor is connected to the other end of one of the short shafts. The U-shaped fixed plate has a long shaft movably installed inside. One end of the long shaft is rotatably connected to the U-shaped fixed plate via a bearing, and the other end of the long shaft movably passes through one side of the inner wall of the U-shaped fixed plate and extends to the other side of the inner wall of the U-shaped fixed plate, and is fixedly fitted with a second pulley.
[0014] The gears mesh with each other. When the motor drives one of the short shafts connected to it to rotate, the meshing of the gears causes the other short shaft to rotate synchronously in the opposite direction. This transmission method ensures precise synchronization of the rotation of the two short shafts, enabling the relevant moving parts on both sides of the device to work in a coordinated manner.
[0015] Preferably, the second pulley is connected to the first pulley via a toothed chain drive. A cross-shaped engaging groove is provided at the other end of the long shaft. A second gear is fixedly sleeved on the outer wall of the long shaft. The second gear is positioned between the inner walls of the U-shaped fixed plate. A connecting base plate is fixedly installed on the front of the U-shaped fixed plate. An electric guide rail is fixedly installed on the top of the connecting base plate. A slide block is slidably connected to the outer wall of the electric guide rail. A connecting vertical plate is fixedly installed on the top of the slide block. A cross-shaped engaging block is fixedly installed on the back of the connecting vertical plate. The cross-shaped engaging block engages with the long shaft via the cross-shaped engaging groove. The second gear meshes with the toothed chain.
[0016] The cross-shaped engagement groove on the long shaft engages with the cross-shaped engagement block on the back of the connecting vertical plate. The movement of the slide is controlled by an electric guide rail, which allows the cross-shaped engagement block and the cross-shaped engagement groove to engage and disengage.
[0017] This patent provides a device for lifting and cleaning silicon material in a water-quenched pure water tank. It has the following beneficial effects:
[0018] (1) This patent uses the rotation of gear two to drive the meshing toothed chain to move. One end of the toothed chain is fixedly connected to the connecting block, which is installed between the movable plates. When the toothed chain moves, it pulls the connecting plate to move, thereby driving the connecting frame to move upward in the pure water tank. The grid plate and polyurethane screen inside the connecting frame filter and lift the silicon material in the pure water tank, bringing the silicon material out of the water. At the same time, the connecting block fixedly installed at one end of the toothed chain moves downward due to gravity, which drives the movable plate to slide downward on the outer wall of the guide rod. This achieves the effect of directly lifting the bottom silicon material for easy cleaning, improving production efficiency, and reducing production costs.
[0019] (2) When it is necessary to replace the grating plate and polyurethane screen in the connecting frame, press the second locking block. The second locking block slides along the guide rod and compresses the spring, so that the second locking block disengages from the locking hole of the connecting frame. Then lift the first locking block upwards to disengage from the locking groove of the connecting frame. The connecting frame can then be removed for cleaning or replacement of the grating plate and polyurethane screen. After replacement, the reverse steps can be followed for installation, thus achieving the effect of convenient replacement, cleaning and maintenance of the grating plate and polyurethane screen.

Detailed Implementation
[0027] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0028] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this patent, and should not be construed as limiting this patent.
[0029] Example 1:
[0030] A preferred embodiment of the silicon material lifting and cleaning device for a water-quenched pure water tank provided by this patent is shown in Figures 1-4: The device includes a pure water tank 1, with support legs 2 uniformly fixedly installed at the bottom of the pure water tank 1, a controller 3 on the front of the pure water tank 1, and a lifting and cleaning assembly 4 on the outside of the pure water tank 1. The lifting and cleaning assembly 4 includes: a cleaning component 41, disposed inside the pure water tank 1; and a driving component 42, disposed outside the pure water tank 1. The cleaning component 41 includes: a support base plate 411, fixedly installed on both sides of the outer wall of the pure water tank 1; and a connecting frame 417, movably disposed inside the pure water tank 1. Guide rods 412 are symmetrically fixedly installed on the top of the support base plate 411, and a limiting square plate 413 is fixedly installed at the top of the guide rods 412. Movable plates 414 are slidably sleeved on the outer wall of the guide rods 412, and connecting blocks 415 are fixedly installed between the movable plates 414. A toothed chain 416 is fixedly installed on the top of the connecting blocks 415, and the other end of the toothed chain 416 is fixedly... A connecting plate 4111 is fixedly installed, and a locking block 4112 is fixedly installed on the bottom of the connecting plate 4111. A movable groove is symmetrically opened on one side of the locking block 4112. A guide rod 4113 is fixedly installed on the locking block 4112 through the movable groove. A locking block 4114 is slidably sleeved on the outer wall of the guide rod 4113. A spring 4115 is sleeved on the outer wall of the guide rod 4113. One end of the spring 4115 is fixedly connected to the locking block 4112, and the other end of the spring 4115 is connected to the locking block 4112. The second 4114 is fixedly connected, and the first 4112 is slidably connected to the second 4112 through the movable groove. The inside of the connecting frame 417 is provided with a grid plate 418, and the top of the grid plate 418 is provided with a polyurethane screen 419. The top of the connecting frame 417 is symmetrically provided with a locking groove. The connecting frame 417 is locked and connected to the first 4112 through the locking groove. The outer walls of the connecting frame 417 are symmetrically provided with locking holes on both sides. The locking holes are connected to the locking groove and are adapted to the second 4114.
[0031] Furthermore, in this embodiment, the rotation of gear 429 drives the meshing gear chain 416 to move. One end of gear chain 416 is fixedly connected to connecting block 415, which is installed between movable plates 414. When gear chain 416 moves, it pulls connecting plate 4111 to move, thereby driving connecting frame 417 to move upward in pure water tank 1. The grid plate 418 and polyurethane screen 419 inside connecting frame 417 filter and lift the silicon material in pure water tank 1, carrying the silicon material out of the water. At the same time, the connecting block 415, which is fixedly installed at one end of gear chain 416, moves downward due to gravity, while simultaneously pulling... The movable plate 414 slides downward on the outer wall of the guide rod 412. When it is necessary to replace the grid plate 418 and polyurethane screen 419 in the connecting frame 417, press the locking block 2 4114. The locking block 2 4114 slides along the guide rod 4113 and compresses the spring 4115, so that the locking block 2 4114 disengages from the locking hole of the connecting frame 417. Then lift the locking block 1 4112 upward, so that the locking block 1 4112 disengages from the locking groove of the connecting frame 417. The connecting frame 417 can then be removed for cleaning or replacement of the grid plate 418 and polyurethane screen 419. After replacement, install in reverse order.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the silicon material lifting and cleaning device for a water-quenched pure water tank provided by this patent is shown in Figures 1-4: The driving component 42 includes: a short shaft 421, symmetrically and movably arranged on the front of the pure water tank 1; a motor 422, fixedly installed on the front of the pure water tank 1; and U-shaped fixing plates 428, respectively fixedly installed on both sides of the outer wall of the pure water tank 1; one end of the short shaft 421 is rotatably connected to the pure water tank 1 through a bearing, and a gear 423 and a pulley 424 are respectively fixedly sleeved on the outer wall of the short shaft 421. The gear 423 is arranged between the pulley 424 and the pure water tank 1, and the gears 423 are meshed together. The output end of the motor 422 is connected to the other end of one of the short shafts 421. A long shaft 427 is movably arranged inside the U-shaped fixing plate 428. One end of the long shaft 427 is rotatably connected to the U-shaped fixing plate 428 through a bearing, and the other end of the long shaft 427 movably passes through the U-shaped fixing plate 428. One side of the inner wall of the fixed plate 428 extends to the other side of the inner wall of the U-shaped fixed plate 428, and a second pulley 425 is fixedly sleeved thereon. The second pulley 425 and the first pulley 424 are connected by a belt 426. The other end of the long shaft 427 has a cross-shaped engagement groove. The outer wall of the long shaft 427 is fixedly sleeved with a second gear 429. The second gear 429 is located between the inner walls of the U-shaped fixed plate 428. A connecting device is fixedly installed on the front side of the U-shaped fixed plate 428. The base plate 4211 is connected to the top of the electric guide rail 4212, and the outer wall of the electric guide rail 4212 is slidably connected to the slide block 4213. The top of the slide block 4213 is fixedly installed with the connecting vertical plate 4214, and the back of the connecting vertical plate 4214 is fixedly installed with the cross engagement block 4215. The cross engagement block 4215 is engaged with the long shaft 427 through the cross engagement groove. The gear 429 is meshed with the gear chain 416.
[0034] Furthermore, in this embodiment, by activating the electric guide rail 4212, the slide block 4213 on the electric guide rail 4212 moves, causing the cross engagement block 4215 on the back of the connecting vertical plate 4214 to separate from the cross engagement slot of the long shaft 427. Then, the motor 422 is activated, and the output end of the motor 422 drives the short shaft 421 connected to it to start rotating. Since the gear 423 fixedly sleeved on the short shaft 421 meshes with each other, when one short shaft 421 rotates, the other short shaft 421 will rotate synchronously in the opposite direction. During the rotation of the short shaft 421, the pulley 424 on its outer wall also rotates accordingly. Through the transmission of the belt 426, the pulley 425 on the long shaft 427 inside the U-shaped fixed plate 428 rotates, thereby driving the long shaft 427 to rotate. When the long shaft 427 rotates, the gear 429 on its outer wall also rotates synchronously.
[0035] When cleaning the precipitated silica material in the pure water tank, the electric guide rail 4212 is activated. The slide block 4213 on the electric guide rail 4212 moves, causing the cross-shaped locking block 4215 on the back of the connecting vertical plate 4214 to separate from the cross-shaped locking groove of the long shaft 427. Then, the motor 422 is activated, and the output end of the motor 422 drives the connected short shaft 421 to start rotating. Since the gear 423 fixedly sleeved on the short shaft 421 meshes with each other, when one short shaft 421 rotates, the other short shaft 421 will rotate synchronously in the opposite direction. During the rotation of the short shaft 421, the outer wall of its skin... The pulley 424 also rotates, and through the transmission of the belt 426, the pulley 425 on the long shaft 427 inside the U-shaped fixed plate 428 rotates, thereby driving the long shaft 427 to rotate. When the long shaft 427 rotates, the gear 429 on its outer wall also rotates synchronously. At this time, the rotation of the gear 429 will drive the meshing toothed chain 416 to move. One end of the toothed chain 416 is fixedly connected to the connecting block 415. The connecting block 415 is installed between the movable plates 414. When the toothed chain 416 moves, it will pull the connecting plate 4111 to move, thereby driving the connecting frame 417 to move in pure water. The water tank moves upward inside the box 1. The grid plate 418 and polyurethane screen 419 inside the connecting frame 417 filter and lift the silica material in the pure water tank 1, carrying the silica material out of the water. At the same time, the connecting block 415 fixedly installed at one end of the toothed chain 416 moves downward due to gravity, which drives the movable plate 414 to slide downward on the outer wall of the guide rod 412. When the top of the pure water tank 1 is moved, the slide block 4213 on the electric guide rail 4212 is moved, so that the cross engagement block 4215 on the back of the connecting vertical plate 4214 engages with the cross engagement groove of the long shaft 427, thereby fixing the long shaft 427 and the gear. As for the second component 429 and the cleaning component 41, when it is necessary to replace the grating plate 418 and polyurethane screen 419 in the connecting frame 417, press the second locking block 4114. The second locking block 4114 slides along the guide rod 4113 and compresses the spring 4115, so that the second locking block 4114 disengages from the locking hole of the connecting frame 417. Then lift the first locking block 4112 upwards, so that the first locking block 4112 disengages from the locking groove of the connecting frame 417. The connecting frame 417 can then be removed for cleaning or replacement of the grating plate 418 and polyurethane screen 419. After replacement, install in reverse order.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this patent and is not intended to limit this patent. Although this patent has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this patent should be included within the protection scope of this patent.
