Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser cutting cooling technology, in particular, to a fiber laser double-path cooling water machine with filtering function. BACKGROUND

[0002] The fiber laser double-path cooling water machine is a refrigeration equipment specially used for cooling fiber laser equipment, which can provide cooling for laser and laser head at the same time, improve cooling efficiency, ensure stable operation of the equipment, and generally consists of a compressor, a condenser, a throttling device (expansion valve or capillary tube), an evaporator and a water pump, etc. The working principle is that the refrigeration system of the cooling water machine cools the water, and the water pump sends the low-temperature cooling water into the equipment that needs to be cooled. The cooling water rises in temperature after taking away the heat and flows back to the cooling water machine for cooling again and then is delivered back to the equipment.

[0003] Since the entire cooling system is a circulating loop, impurities in the water storage structure inside the cooling water machine and the external pipeline will flow into and through the cooling structure inside the laser and laser head along with the circulation of the cooling liquid. The precise cooling structure inside the laser head and the laser is the most vulnerable and most easily affected part of the entire system. In order to reduce the impact of impurities on the laser and the laser head, a filter device is generally added to the loop. However, since the filter device is usually embedded in the dense pipeline and surrounded by pumps, valves, sensors, etc., when the filter device is disassembled, multiple sections of pipeline need to be disassembled, and the surrounding components such as pumps and valves also need to be disassembled, which is time-consuming and labor-intensive, making it inconvenient to clean the filter device, thereby causing a decrease or interruption in flow after long-term use, resulting in a significant reduction in cooling effect, reducing heat transfer efficiency, increasing thermal resistance, and causing the working temperature of the laser and the laser head to rise, thereby affecting the cooling efficiency.

Two groups of pipe joints are arranged on the cold water machine body 2, each group of pipe joints is provided with two pipe joints, one group of pipe joints comprises a high-temperature water inlet joint 3 and a high-temperature water outlet joint 4, and the other group of pipe joints comprises a low-temperature water inlet joint 5 and a low-temperature water outlet joint 6. The mounting rack 7 is fixedly installed on the device shell 1, and the output ends of the high-temperature water outlet joint 4 and the low-temperature water outlet joint 6 are both provided with the water outlet filtering assembly for treating the discharged water. The water outlet filtering assembly comprises a water outlet storage tank 8, a first partition plate 9, a water outlet pipe 10 and a water filtering part. The output ends of the high-temperature water outlet joint 4 and the low-temperature water outlet joint 6 are both communicated with the water outlet storage tank 8, and the two water outlet storage tanks 8 are both fixedly installed on the mounting rack 7. Among them, the bottoms of the two water outlet storage tanks 8 are both provided with inclined surfaces, so that when part of impurities are deposited at the bottoms of the water outlet storage tanks 8, the impurities can be deposited at a lower position under the action of the inclined surfaces, and then the impurities are discharged through the setting of the first valve 14. The bottoms of the two water outlet storage tanks 8 are both communicated with the first valve 14, the first partition plate 9 is fixedly installed inside the water outlet storage tank 8, and there is a gap between the bottom of the first partition plate 9 and the inner bottom wall of the water outlet storage tank 8. The bottoms of the two water outlet storage tanks 8 are both fixedly installed with the water outlet pipe 10, and the input end of the water outlet pipe 10 is inside the water outlet storage tank 8 and is higher than the bottom surface of the first partition plate 9. The interiors of the two water outlet storage tanks 8 are both installed with the water filtering part for filtering the output water.

[0054] It should be noted that the cold water machine body 2 is composed of a compressor, a condenser, a throttling device (an expansion valve or a capillary tube), an evaporator and a water pump, and its working principle is that the refrigeration system of the cold water machine body 2 cools the water, and the water pump sends the low-temperature cooled water into the low-temperature water outlet joint 6 and into the equipment that needs to be cooled. The cooling water is heated after taking away the heat and is returned to the cold water machine through the low-temperature water inlet joint 5, and is transported back to the equipment after being cooled again.

[0055] When the water pump needs to transport cooling water with a certain temperature, the water pump will first send it into the matching heater, and after being heated to the target temperature, the cooling water is discharged from the high-temperature water outlet joint 4 and enters the equipment that needs to be cooled. The cooling water after use is transported back to the equipment through the high-temperature water inlet joint 3.

[0056] Among them, the cooling medium allowed to be used by the cold water machine body 2 is soft water such as pure water, distilled water and high-purity water. It is prohibited to use oily liquid, liquid containing solid particles, liquid with corrosive property and the like. The water outlet filtering assembly and the water inlet filtering assembly and the cooling water are cleaned and replaced regularly (recommended about three months) to ensure the normal operation of the cold water machine body 2.

[0057] The refrigeration system of the water chiller, the refrigerant in the evaporator coil is vaporized into steam by absorbing the heat of the backflow water, the compressor continuously extracts the generated steam from the evaporator and compresses it, the high-temperature and high-pressure steam after compression is sent to the condenser to release heat (heat is removed by the fan) and condenses into high-pressure liquid, which enters the evaporator after being reduced in pressure by the throttling device, vaporizes again, absorbs the heat of the water, and circulates in this way, and the user can set or observe the water temperature working state through the temperature controller.

[0058] It should be noted that when the temperature of the laser head shell or internal optical elements is lower than the dew point temperature of the ambient air, the water vapor in the air will condense into liquid water (that is, dewing), and the dew attached to the optical surfaces such as the laser output window, the mirror, the focusing mirror, etc. causes the laser to be scattered or absorbed, resulting in power reduction and beam quality degradation, in addition, the penetration of dew into the internal circuit or precision mechanical structure will also cause internal short circuit, corrosion and pollution.

[0059] To solve this problem, the cooling water return water temperature is generally increased (that is, the water temperature entering the laser head), to ensure that the surface temperature of the laser head shell and internal key components is always higher than the ambient dew point temperature (usually required to be higher than 5℃).

[0060] It should be noted that before use, the cooling water is poured into the water tank in the water chiller body 2, and when the laser and the laser head cooling structure are connected, the water outlet pipe 10 at the bottom of the water outlet tank 8 communicated with the low-temperature water outlet joint 6 is communicated with the input end of the laser cooling structure, and the water outlet pipe 10 at the bottom of the water outlet tank 8 communicated with the high-temperature water outlet joint 4 is communicated with the input end of the laser head cooling structure; Then the water inlet pipe 17 at the bottom of the water inlet tank 15 communicated with the low-temperature water inlet joint 5 is communicated with the output end of the laser cooling structure, and the water inlet pipe 17 at the bottom of the water inlet tank 15 communicated with the high-temperature water inlet joint 3 is communicated with the output end of the laser head cooling structure, that is, the communication of the pipeline is completed.

[0061] Specifically, when the laser is cooled, the water pump in the water chiller body 2 is turned on, so that the cooling water is discharged into the corresponding water outlet tank 8 through the low-temperature water outlet joint 6, the cooling water in the water outlet tank 8 is filtered by the water filtering part, the filtered cooling water flows into the bottom of the water outlet tank 8, and as the water level rises, the cooling water fills the entire water outlet tank 8, and then the cooling water enters the laser cooling structure through the corresponding water outlet pipe 10. The setting, the laser is cooled, and then the cooling water after absorbing heat is transported back to the equipment through the low-temperature water inlet joint 5 through the setting of the water inlet filtering assembly.

[0062] When the laser head is cooled, the water pump first sends the cooling water into the matching heater. When the water temperature reaches the required temperature, it flows into the corresponding water outlet tank 8 through the high-temperature water outlet joint 4. Repeat the above steps, so that the cooling water enters the corresponding water outlet pipe 10, and then enters the inside of the laser head cooling structure to dissipate heat. Then the cooling water is transported back to the equipment through the high-temperature water inlet joint 3 through the setting of the water inlet filter assembly.

[0063] As shown in the above, Figure 4 , Figure 5 The water filtering part includes a mounting groove 11, a filter frame 12 and a filter core 13. The inside of each water outlet tank 8 is provided with a mounting groove 11. The inside of each mounting groove 11 is sealed and detachably mounted with a filter frame 12. The tail of the filter frame 12 is sealed and abuts against the first partition plate 9. The inside of each filter frame 12 is detachably mounted with a filter core 13.

[0064] Specifically, when the cooling water passes through the filter core 13, the cooling water is filtered, thereby improving the safety during cooling. When it is necessary to clean or replace the filter core 13, the filter frame 12 is pulled out of the mounting groove 11, and the filter core 13 can be cleaned and replaced.

[0065] As shown in the above, Figures 6 to 9 The output ends of the high-temperature water inlet joint 3 and the low-temperature water inlet joint 5 are both mounted with a water inlet filter assembly for processing the water entering the cold water machine body 2. The water outlet filter assembly and the water inlet filter assembly are both mounted on the mounting rack 7. The water inlet filter assembly includes a water inlet tank 15, a second partition plate 16, a water inlet pipe 17, a filtering part and a cleaning part. The input ends of the high-temperature water inlet joint 3 and the low-temperature water inlet joint 5 are both communicated with the water inlet tank 15. The two water inlet tanks 15 are both fixedly installed on the mounting rack 7. The second partition plate 16 is fixedly installed in the water inlet tank 15. The second partition plate 16 divides the water inlet tank 15 into a filtering area and a drainage area. The bottoms of the two water inlet tanks 15 and the bottom of the second partition plate 16 are both provided with inclined surfaces, so that when some impurities are deposited on the bottom of the water inlet tank 15 or the bottom of the second partition plate 16, the impurities are deposited in a lower position under the action of the inclined surface, and then the impurities are discharged through the setting of the second valve 18. The water inlet tank 15 is provided with two second valves 18. One second valve 18 is communicated with the bottom of the water inlet tank 15. The other second valve 18 is communicated with the upper part of the bottom of the second partition plate 16. The bottoms of the two water inlet tanks 15 are both fixedly installed with the water inlet pipe 17. The output end of the water inlet pipe 17 is located in the filtering area. The two water inlet tanks 15 are both installed with the filtering part for filtering the water entering the high-temperature water inlet joint 3 and the low-temperature water inlet joint 5. The cleaning part is installed in the filtering part for cleaning the impurities on the filtering part.

[0066] Specifically, when the cooling water in the laser and the laser head is transported back to the corresponding water inlet pipe 17, the cooling water first enters the filter area in the water inlet tank 15, and then is filtered through the filter part. After filtering, the cooling water returns to the inside of the water cooler body 2 through the corresponding high-temperature water inlet joint 3 and the low-temperature water inlet joint 5. After a period of time, the filter part may be blocked. At this time, through the setting of the cleaning part, the impurities outside the filter part can be scraped off, so as to restore the normal work of the filter part and continue to filter the impurities entering the water inlet tank 15, thereby reducing the maintenance frequency of the filter part.

[0067] As shown in the above, Figures 6 to 9 The filter part includes a mounting cylinder 19, a positioning cylinder 20, and a water filtering member. The two water inlet tanks 15 are fixedly installed with a plurality of mounting cylinders 19 at equal distances. A plurality of groups of positioning cylinders 20 are fixedly installed between the inner side wall of the water inlet tank 15 and the second partition plate 16. Each group of positioning cylinders 20 is symmetrically provided with two positioning cylinders 20. The plurality of mounting cylinders 19 and the plurality of groups of positioning cylinders 20 are coaxially arranged one by one. The water filtering member is installed in each mounting cylinder 19 for filtering water.

[0068] Specifically, the water filtering member needs to be installed in the mounting cylinder 19 during use. The position of the water filtering member in contact with the positioning cylinder 20 slides and sealingly abuts the inner side of the positioning cylinder 20. When the cooling water enters the water inlet tank 15, the cooling water enters the drainage area through the design of the water filtering member and the setting of the water filtering assembly. Then the water in the drainage area can be drained through the corresponding high-temperature water inlet joint 3 or low-temperature water inlet joint 5.

[0069] As shown in the above, Figures 6 to 9 The water filtering member includes a mounting bracket 21, a drainage groove 23, and a filter cylinder 24. The mounting bracket 21 is detachably installed in each mounting cylinder 19. The mounting bracket 21 abuts the inner wall of the positioning cylinder 20. The mounting bracket 21 is fixedly installed with a sealing ring 22 at the position in contact with the second partition plate 16. The sealing ring 22 sealingly abuts the second partition plate 16. The plurality of mounting brackets 21 are located in the drainage area. The drainage groove 23 is formed in each mounting bracket 21. The drainage groove 23 is arranged at equal angles in a circumferential shape with the mounting bracket 21 as the center. The drainage groove 23 is located between the corresponding two positioning cylinders 20. The filter cylinder 24 is rotatably installed at the tail end of each mounting bracket 21. The filter cylinder 24 is located in the filtering area.

[0070] Specifically, when installing the corresponding mounting frame 21, the mounting frame 21 is installed inside the corresponding mounting cylinder 19, and the installation mode between the two is preferably a threaded installation mode. After the mounting frame 21 is installed inside the mounting cylinder 19, the outer wall of the mounting frame 21 is in sealing abutment with the inner wall of the positioning cylinder 20, and the sealing ring 22 at the tail of the mounting frame 21 is in sealing abutment with the position where the second partition plate 16 is in contact. At this time, the filter cylinder 24 is located in the filtering area. The cooling water in the filtering area enters the inside of the mounting frame 21 after being filtered by the filter cylinder 24, and then enters the inside of the drainage area through the drainage groove 23.

[0071] As shown above, Figure 9 The cleaning part includes a transmission rod 25 and a scraping strip 26. The transmission rod 25 is coaxially and rotatably installed inside each mounting frame 21. The tail end of the transmission rod 25 is fixedly connected with the filter cylinder 24. A knob 27 is fixedly installed at the other end of the filter cylinder 24. A plurality of scraping strips 26 are fixedly installed on each second partition plate 16. The plurality of scraping strips 26 correspond to the plurality of filter cylinders 24 one by one. The inner wall of the scraping strip 26 is in sliding contact with the outer wall of the filter cylinder 24.

[0072] Specifically, when it is necessary to clean the filter cylinder 24, the knob 27 is held and the transmission rod 25 is driven to rotate through the knob 27, so as to drive the corresponding filter cylinder 24 to rotate. Through the arrangement of the corresponding scraping strip 26, the impurities attached to the filter cylinder 24 can be scraped off. The scraped impurities will fall into the bottom of the water inlet tank 15, and the corresponding second valve 18 can be regularly treated.

[0073] The working principle or use process of the present application is as follows:

[0074] When the laser and the laser head are cooled, the water pump in the cold water machine body 2 is turned on, so that the cooling water is discharged into the corresponding water outlet tank 8 through the low-temperature water outlet joint 6 or the high-temperature water outlet joint 4. The cooling water in the high-temperature water outlet joint 4 needs to be heated to the target temperature before entering the corresponding water outlet tank 8. The cooling water in the water outlet tank 8 is filtered by the filter core 13, so as to improve the safety during cooling. When it is necessary to clean or replace the filter core 13, the filter frame 12 is pulled out of the installation groove 11, and the filter core 13 is cleaned and replaced. The filtered cooling water flows into the bottom of the water outlet tank 8, and as the water level rises, the cooling water fills the entire water outlet tank 8. Then, the cooling water enters the laser cooling structure through the corresponding water outlet pipe 10, and cools the laser.

[0075] When the cooling water in the laser and the laser head is transported back to the corresponding water inlet pipe 17, the cooling water first enters the filter area in the water inlet tank 15. Before the cooling water enters the water inlet tank 15, the mounting frame 21 is mounted in the corresponding mounting cylinder 19. The mounting mode between the two is preferably a threaded mounting mode. After the mounting frame 21 is mounted in the mounting cylinder 19, the outer wall of the mounting frame 21 is in sealing abutment with the inner wall of the positioning cylinder 20, and the sealing ring 22 at the tail of the mounting frame 21 is in sealing abutment with the position where the second partition plate 16 is in contact. At this time, the filter cylinder 24 is located in the filter area.

[0076] The cooling water entering the filter area passes through the filter cylinder 24 and enters the mounting frame 21, and then passes through the drain groove 23 and enters the drain area. The water in the drain area can then be discharged into the cold water machine body 2 through the corresponding high-temperature water inlet joint 3 or low-temperature water inlet joint 5. After a period of time, the filter cylinder 24 may be clogged. When it is necessary to clean the filter cylinder 24, hold the knob 27 and rotate the transmission rod 25 through the knob 27 to drive the corresponding filter cylinder 24 to rotate. Through the arrangement of the corresponding scraping strip 26, the impurities attached to the filter cylinder 24 can be scraped off, thereby restoring the normal operation of the filter cylinder 24. The scraped impurities will fall to the bottom of the water inlet tank 15, and through the arrangement of the corresponding second valve 18, it can be treated regularly.

[0077] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
