Description

Technical Field

[0001] This application relates to the field of glass processing, and in particular to a circulating water cooling processing apparatus for glass polishing sheets. Background Technology

[0002] Glass polishing pads are tools or consumables used for polishing glass surfaces. Their main function is to finely process the glass surface through friction and grinding to remove scratches, burrs, and defects, making the glass surface smooth, flat, and transparent, thus meeting the quality requirements of high-precision glass products (such as optical glass, display screen glass, and precision instrument glass). During the polishing process, water or polishing fluid is usually used in conjunction with the polishing pads to cool, lubricate, and assist in the grinding process.

[0003] The existing publication number CN214199354U discloses a glass processing cooling device, but it still has the following shortcomings in practical use:

[0004] During the cooling process, the heat needs to be conducted from the glass processing module to the heat sink first, and then carried away by the silicone oil in the serpentine heat pipe. This is an indirect heat dissipation method with a long heat conduction path and a cooling delay. When the glass processing module generates a large amount of heat in a short period of time, it cannot be cooled down in time, causing local overheating of the glass and resulting in cracks or deformation, which in turn affects the glass processing quality. Utility Model Content

[0005] To address the problem of localized overheating caused by the inability to cool down the glass in a timely manner due to the large amount of heat generated during glass processing, this application provides a circulating water cooling processing device for glass polishing sheets.

[0006] The glass polishing sheet circulating water cooling processing device provided in this application adopts the following technical solution:

[0007] A glass polishing sheet circulating water cooling processing device includes a water tank and a processing base. A water collection hole is provided on the side of the processing base away from the water tank. A circulating water cooling pipeline is provided between the water tank and the processing base for guiding the water used in glass processing back into the water tank.

[0008] The circulating water cooling pipeline includes a thermosiphon conduit and a connecting pipe disposed on one side of the water tank surface. The surface of the thermosiphon conduit is fitted with heat dissipation fins for increasing the heat dissipation area. The heat dissipation fins are spiral in shape. A sealed cavity for filling the phase change working fluid is opened inside the thermosiphon conduit. A filter assembly for filtering water is disposed inside the connecting pipe.

[0009] By adopting the above technical solution, water is cooled without power by utilizing the phase change circulation of the phase change working medium inside the thermosiphon duct. The heat dissipation area is expanded by the heat dissipation fins to enhance heat release. The water is filtered by the filter assembly before cooling to prevent impurities from interfering with the cooling process and to ensure the stability of the entire cooling process.

[0010] Preferably, the circulating water cooling pipeline further includes a water collection seat fixed on the side of the processing seat away from the water tank surface. The water collection seat has a water collection cavity communicating with the water collection hole inside. The bottom wall of the water collection cavity is an inclined surface. A water guide pipe is fixed on the side wall of the water collection cavity. A positioning ring with a threaded connection to the end of the connecting pipe near the processing seat is fixed on the end of the water guide pipe away from the processing seat.

[0011] By adopting the above technical solution, the water used in the glass processing is introduced into the water collection cavity through the water collection hole, and then into the water guide pipe through the inclined surface of the bottom wall of the water collection cavity. The water is then introduced into the connecting pipe from the inside of the water guide pipe, realizing the water return.

[0012] Preferably, a drain pipe is inserted at the end of the connecting pipe away from the processing seat, a return water pipe is fixed at the end of the drain pipe away from the connecting pipe and fixed to the end of the thermosiphon conduit near the connecting pipe, and an inlet pipe is fixed at the end of the thermosiphon conduit away from the return water pipe and fixed to one side of the water tank surface.

[0013] By adopting the above technical solution, water in the connecting pipe is introduced into the drainage pipe, water is introduced from the drainage pipe into the return pipe, water is introduced from the return pipe into the thermosiphon conduit, water is introduced from the thermosiphon conduit into the inlet pipe, and water is then guided back into the water tank from the inlet pipe, thereby realizing the circulation of water used in glass processing and saving water resources.

[0014] Preferably, the surface of the drainage tube is fixedly provided with an abutting plate that abuts against the end of the connecting tube away from the processing seat, and the end of the drainage tube near the connecting tube is fixedly provided with an insert ring inserted into the connecting tube, and the surface of the insert ring is fixedly provided with a sealing ring for sealing the insert ring and the connecting tube.

[0015] By adopting the above technical solution, by inserting the insertion ring into the connecting pipe and locking the sealing ring inside the connecting pipe, the connection between the drainage pipe and the connecting pipe is detachably connected while sealing the connecting pipe and the drainage pipe. This ensures the stability of water flowing into the return pipe through the drainage pipe and facilitates the maintenance and replacement of the connecting pipe and the filter assembly.

[0016] Preferably, a driving block is provided on one side of the surface of the connecting pipe, and a limiting plate that is slidably disposed on the surface of the connecting pipe is fixed on the side of the driving block near the surface of the connecting pipe. The limiting plate is used to limit the position of the insertion ring.

[0017] By adopting the above technical solution, the limiting plate limits the insertion ring, so that the drainage pipe is limited by the limiting plate during the water flow process, preventing the drainage pipe from detaching from the end of the connecting pipe and away from the water guide pipe.

[0018] Preferably, the limiting plate has a limiting block fixedly disposed on both sides of the surface of the limiting plate and a limiting block slidably disposed on one side of the surface of the connecting pipe, and a spring fixedly disposed inside the connecting pipe is fixedly disposed on one side of the surface of the limiting block.

[0019] By adopting the above technical solution, the limiting plate is limited by the limiting block to prevent the limiting plate from detaching from the surface of the connecting pipe, and the spring force is used to keep the limiting plate always limiting the insertion ring without being subjected to upward pulling force.

[0020] Preferably, the filtration assembly includes a coarse filter screen threaded inside the connecting pipe, the coarse filter screen being used for primary filtration of water, a plurality of connecting posts arranged in a ring fixed at the end of the coarse filter screen away from the processing seat, a fine filter screen being fixed at the end of the connecting posts away from the coarse filter screen for secondary filtration of water, and an activated carbon plate being fixed at the end of the fine filter screen away from the connecting posts for tertiary filtration of water.

[0021] By adopting the above technical solution, the water flows through a coarse filter, a fine filter, and an activated carbon plate in sequence during the process of water flow inside the connecting pipe, and is purified to remove impurities in the water. The water is cooled after being filtered through the coarse filter, fine filter, and activated carbon plate, which ensures the cooling effect of the thermosiphon duct and heat dissipation fins on the water.

[0022] Preferably, the pore size of the fine filter screen is smaller than that of the coarse filter screen.

[0023] By adopting the above technical solution, the pore size of the fine filter screen is set to be smaller than that of the coarse filter screen, so that the coarse filter screen can filter out large particulate impurities, preventing large particulate impurities from contacting the fine filter screen and preventing large particulate impurities from clogging the fine filter screen.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The water used in glass processing is recycled through a circulating water cooling pipeline, which greatly saves water resources. At the same time, the phase change working fluid in the thermosiphon duct is cooled without power by the "evaporation-flow-condensation-reflux" cycle. The spiral heat dissipation fins expand the heat dissipation area, ensuring stable cooling effect and avoiding the impact of high temperature on processing accuracy.

[0026] 2. The filter assembly employs a three-stage filtration system consisting of a coarse filter, a fine filter (with a smaller pore size than the coarse filter), and an activated carbon plate. This sequentially removes large particles, fine particles, and odor impurities, preventing pipe blockage and reduced cooling efficiency. Furthermore, the components are detachable via threaded connections and ring seals, facilitating regular disassembly, maintenance, and replacement of filter elements to ensure long-term stable operation.

[0044] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0045] This application discloses a circulating water cooling processing device for glass polishing sheets.

[0046] Reference Figure 1 A circulating water cooling processing device for glass polishing sheets includes a glass polishing machine body 1. The glass polishing machine body 1 is existing technology, and its principle will not be detailed here. A water tank 2 and a processing seat 3 are installed on the surface of the glass polishing machine body 1. A sealing plug is inserted into the surface of the water tank 2. When polishing agent needs to be added, the user only needs to remove the sealing plug from the surface of the water tank 2 and inject the polishing agent into the interior of the water tank 2 through the connection between the sealing plug and the surface of the water tank 2. After injection, the sealing plug is reinserted into the connection between the water tank 2 and the sealing plug. A water collection hole 31 is opened on the side of the processing seat 3 away from the surface of the water tank 2. The glass polishing machine body 1 includes:

[0047] I. Rack and Base

[0048] Function: To support all components of the equipment, ensure overall stability, and reduce vibration during the polishing process (vibration can affect polishing accuracy).

[0049] Features: Usually made of cast iron or steel welded together, it has high rigidity and resistance to deformation. Some high-precision models will undergo aging treatment to eliminate internal stress.

[0050] II. Glass fixing mechanism (workbench)

[0051] Function: To fix the glass to be polished, ensuring its stable position during the polishing process and preventing displacement that could lead to uneven polishing.

[0052] The glass polishing machine body 1 adopts a vacuum suction cup worktable: negative pressure is generated by a vacuum pump to adsorb glass (suitable for flat glass, especially large-size glass).

[0053] III. Polishing Head Assembly (Core Working Component)

[0054] Function: To mount polishing tools (polishing discs) and provide polishing pressure, speed and motion trajectory, directly contacting the glass surface to complete polishing.

[0055] Main components:

[0056] Polishing wheel / polishing pad: The material is selected according to the process (such as wool wheel, sponge pad, diamond grinding disc, etc.), used to transfer polishing agent and grinding force.

[0057] Drive unit: Consists of a motor (such as a servo motor or frequency converter) and a reducer, which controls the rotation speed of the polishing head (usually adjustable to adapt to different polishing stages).

[0058] Pressure adjustment mechanism: The pressure of the polishing head on the glass is adjusted by a cylinder, hydraulic cylinder or precision lead screw (the uniformity of pressure directly affects the polishing effect).

[0059] IV. Transmission and Feed System

[0060] Function: To control the movement trajectory of the worktable or polishing head (such as linear, rotary, or combined motion) to achieve automated polishing.

[0061] Core components:

[0062] Guide rails and sliders: ensure the straightness and accuracy of the motion (high-precision linear guide rails are commonly used).

[0063] Ball screw / rack gear: converts the rotational motion of the motor into linear motion and controls the feed accuracy (the higher the accuracy of the screw, the better the polishing uniformity).

[0064] Servo control system: The motor is controlled by a PLC or numerical control system (CNC) to achieve precise adjustment of speed and position (suitable for highly automated models).

[0065] V. Polishing compound supply system

[0066] Function: It continuously provides polishing agents (such as polishing fluid, polishing paste, water, etc.) to the polishing area, thereby lubricating, cooling, and enhancing the polishing effect.

[0067] composition:

[0068] Water tank 2: Stores polishing agent.

[0069] Delivery device: The polishing agent is precisely sprayed onto the polishing contact point through pumps (such as gear pumps or peristaltic pumps), pipes, and nozzles.

[0070] VI. Control System

[0071] Function: To control the operating parameters of the equipment (such as polishing time, speed, pressure, motion trajectory, etc.) to achieve manual or automated operation.

[0072] Main components:

[0073] Operation panel: Parameters can be set via buttons and touch screen, and the device operating status can be displayed.

[0074] PLC or numerical control system: The core control unit receives sensor signals and drives actuators (such as motors and cylinders).

[0075] Sensors such as pressure sensors (monitoring polishing pressure), displacement sensors (controlling feed rate), and level sensors (monitoring polishing compound level) improve control accuracy.

[0076] VII. Auxiliary Systems

[0077] Cooling system: Reduces the temperature of the polishing head and glass through water or air cooling to prevent glass deformation or damage to polishing tools due to high temperatures.

[0078] Reference Figures 1-7 A circulating water cooling pipe 4 is provided between the water tank 2 and the processing base 3 to guide the water used during glass processing back into the water tank 2. The circulating water cooling pipe 4 includes a water collection base 41 fixed on the side of the processing base 3 away from the surface of the water tank 2. The water collection base 41 has a water collection cavity 411 inside that communicates with the water collection hole 31. The bottom wall of the water collection cavity 411 is an inclined surface with an inclination angle of 3-6°. A water guide pipe 42 is fixed on the side wall of the water collection cavity 411. The water guide pipe 42 is located at the bottom end of the inclined surface of the bottom wall of the water collection cavity 411. The water collection cavity 411 is connected to the water guide pipe 42. A positioning ring 421 is fixed at the end of the water pipe 42 away from the processing seat 3. The surface of the positioning ring 421 is provided with an external thread. A connecting pipe 43 is provided at the end of the water pipe 42 away from the water collecting seat 41. The water pipe 42 and the connecting pipe 43 are connected. A positioning groove 434 is opened at the end of the connecting pipe 43 near the water pipe 42. The inner wall of the positioning groove 434 is provided with an internal thread that meshes with the external thread. The positioning ring 421 can detachably fix the end of the connecting pipe 43 near the water pipe 42 by meshing the external thread and the internal thread, thereby completing the connection between the water pipe 42 and the connecting pipe 43.

[0079] By manually rotating the connecting pipe 43, the connecting pipe 43 and the positioning ring 421 are fixed together by the engagement of the internal and external threads, thereby connecting the connecting pipe 43 and the water guide pipe 42, allowing the water inside the water collection chamber 411 to be introduced into the water guide pipe 42, and the water inside the water guide pipe 42 to be introduced into the connecting pipe 43, thus realizing the export of water from the water collection chamber 411.

[0080] Reference Figures 1-7 A drain pipe 45 is inserted at the end of the connecting pipe 43 away from the processing seat 3. A return water pipe 46 is fixed at the end of the drain pipe 45 away from the connecting pipe 43. A thermosiphon conduit 47 is fixed at the end of the return water pipe 46 away from the drain pipe 45. A heat dissipation fin 471 for expanding the heat dissipation area is sleeved on the surface of the thermosiphon conduit 47. The heat dissipation fin 471 is spiral. The gap between the thermosiphon conduit 47 and the heat dissipation fin 471 is filled with thermally conductive silicone grease. The fluidity of the silicone grease adaptively fills the irregular gap between the spiral surface and the thermosiphon conduit 47, ensuring that each section of the heat dissipation fin 471 can uniformly receive the heat transferred by the thermosiphon conduit 47, avoiding heat dissipation dead corners due to poor local contact, and ensuring the stability of the overall heat dissipation effect. A sealed cavity 472 is opened inside the thermosiphon conduit 47 for filling phase change working fluid (such as ethanol, Freon and other low boiling point media).

[0081] An inlet pipe 48 is fixedly provided at the end of the thermosiphon conduit 47 away from the return water pipe 46. The end of the inlet pipe 48 away from the thermosiphon conduit 47 passes through one side of the surface of the water tank 2. The surface of the end of the inlet pipe 48 away from the thermosiphon conduit 47 is sealed to one side of the surface of the water tank 2 by a sealing ring. A support plate 481 is fixedly provided on the surface of the inlet pipe 48. The end of the support plate 481 away from the inlet pipe 48 is fixedly provided on the base surface of the glass polishing machine body 1. A micro booster pump is installed inside the water tank 2, and the inlet of the micro booster pump is connected to the end of the inlet pipe 48 away from the thermosiphon conduit 47.

[0082] It should be noted that the pretreatment of the thermosiphon tube 47 involves first connecting the thermosiphon tube 47 to a vacuum device and then using a vacuum pump to evacuate the sealed cavity 472 inside the cavity. The purpose of this is to remove the original air and other non-condensable gases from the cavity, as the presence of these gases will occupy space, affect the evaporation and condensation process of the phase change working fluid, reduce heat transfer efficiency, and may also cause adverse phenomena such as oxidation, thus shortening the service life of the device. Only when the vacuum level reaches the predetermined requirements, such as 0.1 Pa or even lower (the specific value depends on the characteristics of the selected phase change working fluid and the design standards of the thermosiphon tube 47), can the next step be carried out.

[0083] Based on the designed injection rate of the thermosiphon conduit 47, the selected phase change working fluid is injected into the sealed cavity 472 through a specialized injection device. The common injection rate is generally between 50% and 70%. During the filling process, the injection volume needs to be precisely controlled. The volume or mass of the injected phase change working fluid can be monitored in real time through metering devices on the injection device, such as high-precision flow meters or weighing sensors, to ensure that the design requirements are met.

[0084] After filling, the thermosiphon conduit 47 should be sealed immediately using reliable sealing methods such as welding and sealant to ensure the airtightness of the sealing cavity 472 and prevent leakage of the phase change working fluid. When welding, welding materials that match the material of the thermosiphon conduit 47 should be selected, and professional welding processes, such as argon arc welding, should be used to ensure that the weld is uniform, strong, and free of defects such as pores and cracks. After sealing, the thermosiphon conduit 47 should be tested for airtightness using methods such as pressure testing and helium mass spectrometry leak detection to ensure that the thermosiphon conduit 47 will not leak during subsequent use.

[0085] The inner diameter of the thermosiphon duct 47 is 10-20mm, and the spacing of the heat dissipation fins 471 is 5-10mm.

[0086] Water inside the connecting pipe 43 is introduced into the drain pipe 45, and from the drain pipe 45 into the return pipe 46. From the return pipe 46 into the thermosiphon conduit 47, the water flows through the thermosiphon conduit 47. During the flow of the water, it absorbs heat through the phase change working fluid in the sealed cavity 472 and rapidly evaporates into a gaseous state. Due to the rapid expansion of volume during evaporation, the gaseous working fluid forms a pressure difference in the sealed cavity 472, pushing it to flow towards the other end with a lower temperature (i.e., the area near the heat dissipation fins 471). After reaching the low-temperature area, the gaseous working fluid releases heat to the external environment through the heat dissipation fins 471 and re-condenses into a liquid state. The liquid working fluid flows back to the high-temperature end (i.e., the area away from the heat dissipation fins 471) under the action of gravity, forming a cycle of "evaporation-flow-condensation-return". This continuously removes the heat from the water in the polishing wheel during glass processing, thus achieving the cooling of the water required for glass processing.

[0087] After being cooled inside the thermosiphon conduit 47, the water enters the inlet pipe 48. From inside the inlet pipe 48, the water returns to the water tank 2 through a micro booster pump, thus realizing the circulation of water required for glass processing and saving water resources.

[0088] Reference Figures 1-7 A receiving plate 451 is fixed on the surface of the drain pipe 45. The side of the receiving plate 451 away from the return pipe 46 abuts against the end of the connecting pipe 43 away from the guide pipe 42. A plug ring 452 is fixed on the end of the drain pipe 45 near the connecting pipe 43. A slot 437 adapted to the plug ring 452 is opened on the end of the connecting pipe 43 near the drain pipe 45. A sealing ring 453 for sealing the plug ring 452 and the connecting pipe 43 is fixed on the surface of the plug ring 452. A sealing groove 433 adapted to the sealing ring 453 is opened inside the slot 437.

[0089] It should be noted that when the side of the contact plate 451 away from the return water pipe 46 abuts against the end of the connecting pipe 43 away from the guide water pipe 42, the surface of the insert ring 452 abuts against the inner wall of the slot 437, and the surface of the sealing ring 453 abuts against the inner wall of the sealing groove 433.

[0090] By inserting the insert ring 452 into the slot 437, the insert ring 452 drives the sealing ring 453 into the slot 437. The sealing ring 453 is squeezed by the inner wall of the slot 437, causing the sealing ring 453 to deform. When the sealing ring 453 moves to be directly opposite the sealing groove 433, the sealing ring 453 loses the squeezing force of the inner wall of the slot 437, and the sealing ring 453 gradually recovers its deformation, gradually filling the sealing groove 433. When the surface of the sealing ring 453 is completely in contact with the inside of the sealing groove 433, the insert ring 452 and the slot 437 are sealed, thereby achieving the sealing of the connecting pipe 43 and the drainage pipe 45. This allows for the detachable installation of the connecting pipe 43 and the drainage pipe 45, facilitating the maintenance and replacement of the connecting pipe 43 and the filter assembly 5.

[0091] Reference Figures 1-7 A driving block 44 is provided on one side of the surface of the connecting pipe 43. One side of the surface of the driving block 44 is U-shaped. A limiting plate 441 is fixed on the side of the driving block 44 near the surface of the connecting pipe 43. A driving space 431 adapted to the limiting plate 441 is opened on the side of the connecting pipe 43 near the surface of the driving block 44. The surface of the limiting plate 441 abuts against the inner wall of the driving space 431, so that the limiting plate 441 can slide stably inside the driving space 431. The limiting plate 441 is used for... The insertion ring 452 is limited, and the limiting block 442 is fixed on both sides of the surface of the limiting plate 441. The inner wall of the driving space 431 is provided with limiting grooves 432 that are adapted to the limiting block 442. The surface of the limiting block 442 abuts against the inner wall of the limiting groove 432, so that the limiting block 442 can slide stably inside the limiting groove 432. A spring 443 is fixed on one side of the surface of the limiting block 442, and the end of the spring 443 away from the limiting block 442 is fixed on the top wall of the limiting groove 432.

[0092] It should be noted that the calculation formula for the limiting block 442 is: F = kx, where F is the external force on the limiting block 442, in N, k is the spring constant of the limiting block 442, in N / m, and x is the deformation of the limiting block 442, in m. The elastic force of the limiting block 442 is then calculated so that it can be used in this application.

[0093] The limiting block 442 limits the limiting plate 441 to prevent the limiting plate 441 from detaching from the surface of the connecting pipe 43, and with the help of the elastic force of the spring 443, the limiting plate 441 is always limited to the insertion ring 452 without being subjected to an upward pulling force.

[0094] When it is necessary to release the restriction of the limiting plate 441 on the insertion ring 452, the user only needs to pull the driving block 44 upward to move the driving block 44 upward. The driving block 44 drives the limiting plate 441 upward, so that the end of the limiting plate 441 away from the driving block 44 gradually enters the driving space 431. When the end of the limiting plate 441 away from the driving block 44 enters the driving space 431, the end of the limiting plate 441 away from the driving block 44 is no longer on the same horizontal line as the surface of the insertion ring 452, thereby releasing the restriction of the limiting plate 441 on the insertion ring 452, so that the drainage pipe 45 can be pulled out from the end of the connecting pipe 43 away from the water guide pipe 42, which is convenient for maintenance or replacement of the connecting pipe 43.

[0095] Reference Figures 1-7 The connecting pipe 43 is equipped with a filter assembly 5 for filtering water. The filter assembly 5 includes a coarse filter screen 51 that is threaded inside the connecting pipe 43. The surface of the coarse filter screen 51 is provided with external threads. The inner wall of the connecting pipe 43 is provided with a threaded groove 435 that engages with the external threads, so that the coarse filter screen 51 is fixed inside the connecting pipe 43 by engaging with the threaded groove 435 through the external threads. The coarse filter screen 51 is used for primary filtration of water. A plurality of connecting posts 511 arranged in a ring are fixed at the end of the coarse filter screen 51 away from the processing seat 3.

[0096] A fine filter screen 52 for secondary filtration of water is fixed at the end of the connecting column 511 away from the coarse filter screen 51. The surface of the fine filter screen 52 is provided with external threads. The inner wall of the connecting pipe 43 is provided with a threaded groove 436 that engages with the external threads, so that the fine filter screen 52 is fixed inside the connecting pipe 43 by engaging with the threaded groove 436 through the external threads. An activated carbon plate 53 for tertiary filtration of water is fixed at the end of the fine filter screen 52 away from the connecting column 511. The pore size of the fine filter screen 52 is smaller than that of the coarse filter screen 51.

[0097] It should be noted that the coarse filter 51 has a pore size of 200-500 microns, which filters larger particles.

[0098] Fine filter screen 52: pore size: approximately 50-100 micrometers, removes fine particles.

[0099] Activated carbon plate 53: Coconut shell activated carbon (common particle diameter is 2-4mm), which can effectively adsorb organic matter in water.

[0100] Replacement cycle: Replace the filter components every 6 months or depending on water quality.

[0101] As water flows inside the connecting pipe 43, it is purified sequentially through a coarse filter 51, a fine filter 52, and an activated carbon plate 53, removing impurities from the water. The water is cooled after being filtered through the coarse filter 51, the fine filter 52, and the activated carbon plate 53, ensuring the cooling effect of the thermosiphon duct 47 and the heat dissipation fins 471. Furthermore, the coarse filter 51 and the fine filter 52 are connected by threads, making it easy to remove the coarse filter 51, the fine filter 52, and the activated carbon plate 53 from inside the connecting pipe 43, preventing the filter assembly 5 from reducing the water circulation flow rate due to long-term use.

[0102] It should be noted that: the water collection base 41, water guide pipe 42, connecting pipe 43, diversion pipe 45, return water pipe 46, and inlet pipe 48 are all made of PVC-U (rigid polyvinyl chloride); the thermosiphon conduit 47 is made of copper; the heat dissipation fins 471 are made of aluminum alloy; the coarse filter 51 and fine filter 52 are made of 304 stainless steel; and the activated carbon plate 53 uses coconut shell activated carbon as the core material, with PP plastic mesh plate as the carrier.

[0103] The polishing agent used in this application is water. The micro booster pump inside the water tank 2 is activated during the glass polishing process. Therefore, when polishing the glass, the micro booster pump inside the water tank 2 is activated by connecting the power supply to the micro booster pump.

[0104] The implementation principle of the circulating water cooling processing device for glass polishing sheets in this application embodiment is as follows: Before polishing the glass, the glass is first fixed on the vacuum suction cup worktable of the glass polishing machine body 1. Then, the pressure adjustment mechanism of the glass polishing machine body 1 is activated to adjust the pressure of the polishing wheel on the glass surface. After adjustment, the drive device is activated so that the drive device of the glass polishing machine body 1 controls the rotation of the polishing wheel to polish the glass. At the same time, the polishing agent supply system is activated so that the water in the water tank 2 is accurately sprayed to the polishing contact point through the pump (such as a gear pump or peristaltic pump), pipes and nozzles to improve the polishing effect of the polishing wheel on the glass.

[0105] Water generated during glass processing is introduced into the water collection chamber 411 through the water collection hole 31. The water is then guided into the water guide pipe 42 through the inclined surface of the bottom wall of the water collection chamber 411. The water in the water guide pipe 42 is then guided into the connecting pipe 43. During the flow of water in the connecting pipe 43, it is purified by passing through the coarse filter screen 51, the fine filter screen 52, and the activated carbon plate 53 in sequence, removing impurities from the water. The coarse filter screen 51 first filters out large particles of impurities in the water, such as larger glass fragments, forming a primary filtration. Then, the fine filter screen 52 further filters out fine particles, such as fine glass powder. Finally, the activated carbon plate 53 adsorbs odors and organic impurities in the water, such as organic components in polishing agent residue, ensuring the cooling effect of the thermosiphon conduit 47 and the heat dissipation fins 471 on the water.

[0106] Water inside the connecting pipe 43 is introduced into the drain pipe 45, and from the drain pipe 45 into the return pipe 46. From the return pipe 46 into the thermosiphon conduit 47, the water flows through the thermosiphon conduit 47. During the flow of the water, it absorbs heat through the phase change working fluid in the sealed cavity 472 and rapidly evaporates into a gaseous state. Due to the rapid expansion of volume during evaporation, the gaseous working fluid forms a pressure difference in the sealed cavity 472, pushing it to flow towards the other end with a lower temperature (i.e., the area near the heat dissipation fins 471). After reaching the low-temperature area, the gaseous working fluid releases heat to the external environment through the heat dissipation fins 471 and re-condenses into a liquid state. The liquid working fluid flows back to the high-temperature end (i.e., the area away from the heat dissipation fins 471) under the action of gravity, forming a cycle of "evaporation-flow-condensation-return". This continuously removes the heat from the water in the polishing wheel during glass processing, thus achieving the cooling of the water required for glass processing.

[0107] After being cooled inside the thermosiphon duct 47, the water enters the inlet pipe 48. From inside the inlet pipe 48, the water returns to the water tank 2 through a micro booster pump, improving the recycling rate and reflux speed of the cooling water, thereby realizing the circulation of water required for glass processing and saving water resources.

[0108] When it is necessary to release the restriction of the limiting plate 441 on the insertion ring 452, the user only needs to pull the driving block 44 upward to move the driving block 44 upward. The driving block 44 drives the limiting plate 441 upward, so that the end of the limiting plate 441 away from the driving block 44 gradually enters the driving space 431. When the end of the limiting plate 441 away from the driving block 44 enters the driving space 431, the end of the limiting plate 441 away from the driving block 44 is no longer on the same horizontal line as the surface of the insertion ring 452, thereby releasing the restriction of the limiting plate 441 on the insertion ring 452, so that the drainage pipe 45 can be pulled out from the end of the connecting pipe 43 away from the water guide pipe 42.

[0109] After the drain pipe 45 is pulled out from the end of the connecting pipe 43 away from the water guide pipe 42, the connecting pipe 43 is rotated counterclockwise so that the connecting pipe 43 gradually moves away from the water guide pipe 42 through the engagement of the positioning groove 434 with the external thread on the surface of the positioning ring 421. When the end of the connecting pipe 43 near the water guide pipe 42 is completely detached from the surface of the positioning ring 421, the connecting pipe 43 has been removed from the positioning ring 421, allowing the user to further process the coarse filter screen 51, fine filter screen 52, and activated carbon plate 53. This facilitates the maintenance or replacement of the connecting pipe 43 and prevents the coarse filter screen 51, fine filter screen 52, and activated carbon plate 53 from becoming clogged due to long-term lack of processing.

[0110] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
