Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a condensing device for a chiller. Background Art

[0002] A chiller is a device that provides cooling water at a constant temperature, flow, and pressure, and is widely used in various industrial and commercial fields. Chillers circulate refrigerant to absorb heat and dissipate it, achieving cooling, temperature control, and constant flow. Chillers are primarily categorized into two types: air-cooled and water-cooled.

[0003] The condenser is a key component in a refrigeration system. Its primary function is to convert high-temperature, high-pressure refrigerant into a liquid or gas-liquid mixture through cooling. In a refrigeration system, the condenser transfers heat from the refrigerant in the tubes to a cooling medium (usually water, due to its excellent cooling properties and low cost), thereby lowering the refrigerant's temperature.

[0004] When the cooling medium in the condenser is water, as the condenser is used for a long time, thick scale will form on the outer wall of the condenser tube. The scale will affect the heat transfer effect, thereby causing the subsequent condensation effect of the condenser to deteriorate, which is a shortcoming. Summary of the Invention

[0005] In order to improve the problem that scale formed on the outer wall of the condenser tube affects the condensation effect of the condenser, the present application provides a condensing device for a chiller.

[0006] The present application provides a condensing device for a chiller using the following technical solution: The cooling water tank is provided with a cooling water inlet and a cooling water outlet, and the cooling water inlet and the cooling water outlet are connected with the cooling water inlet and the cooling water outlet to form a cooling water tank.

[0007] By adopting the above technical solution, workers introduce cooling water into the water inlet pipe, and the cooling water is injected into the condensing tank body and flows out from the water outlet pipe. At the same time, the refrigerant in the chiller flows into the inlet chamber through the hot mass pipe, and then flows into the other end cover through the condenser pipe connected to the inlet chamber, and then flows back to the outlet chamber through the condenser pipe connected to the outlet chamber, and then flows back to the chiller through the cold mass pipe, thereby achieving cooling of the refrigerant. At the same time, the driving component drives the scraper plate to slide, and the scale formed on the condenser pipe is dropped to the inner bottom wall of the condensing tank body. Finally, the scale scraped off is discharged from the condenser tank body by the scale discharge component, thereby solving the cooling effect of the scale formed on the condenser pipe on the refrigerant.

[0008] Optionally, the condensation tank body is placed horizontally, and the drive assembly includes a liquid inlet square tube and a liquid outlet pipe arranged at both ends of the condensation tank body, the liquid outlet pipe is located above the liquid inlet square tube, the distance between the liquid inlet square tube and the end of the condensation tank body is smaller than the distance between the liquid outlet pipe and the end of the condensation tank body, the distance between the liquid inlet square tube and the liquid outlet pipe in the axial direction of the condensation tank body is greater than the width of the scraper plate, a cooling pipe is connected between the water inlet pipe and the two liquid inlet square tubes, a first solenoid valve electrically connected to the control system is arranged on the cooling pipe, a heat exhaust pipe is connected between the water outlet pipe and the two liquid outlet pipes, a second solenoid valve electrically connected to the control system is arranged on the heat exhaust pipe, and a block is provided on the condensation tank body between the liquid inlet square tube and the liquid outlet pipe, and the block is used to abut the scraper plate.

[0009] By adopting the above technical solution, the worker starts the first solenoid valve at one end of the condensation tank body and closes the second solenoid valve through the control system, and at the same time starts the second solenoid valve at the other end of the condensation tank body and closes the first solenoid valve. The cooling water flowing in from the water inlet pipe flows into the end of the condensation tank body along the cooling pipe, the first solenoid valve and the liquid inlet square pipe that open the first solenoid valve in sequence. The cooling water flowing into the condensation tank body pushes the scraper plate to slide. In the process of the scraper plate sliding along the axial direction of the condensation tank body, the scale formed on the condensation tube is scraped off. The cooling water facing the side of the second solenoid valve that opens flows out along the liquid outlet pipe, the heat exhaust pipe, the second solenoid valve and the water outlet pipe that open the second solenoid valve in sequence until the scraper plate abuts the block. At this time, the cooling water flowing in from the water inlet pipe flows out from the liquid outlet pipe on the side of the scraper plate facing away from the block, thereby completing the removal of scale formed on the condensation tube.

[0010] Optionally, a one-way valve is provided between the heat exhaust pipe between the condensation tank body and the second solenoid valve and the condensation tank body, and the connection point between the one-way valve and the condensation tank body is located between the block and the cover shell, and the medium between the end of the condensation tank body and the block flows from the one-way valve to the heat exhaust pipe.

[0011] By adopting the above technical solution, when the scraper plate passes over the liquid outlet pipe and approaches the block, the scraper plate continuously squeezes the cooling water between the end of the condensation tank body and the block. The squeezed cooling water flows through the one-way valve to the heat exhaust pipe, thereby relieving the liquid pressure between the end of the condensation tank body and the block.

[0012] Optionally, the descaling component includes a gate valve provided on the liquid inlet square tube and electrically connected to a control system, the cooling pipe is located between the gate valve and the condensation tank, and the gate valve is used to seal the liquid inlet square tube.

[0013] By adopting the above technical solution, when the scraper plate slides and finally abuts the block, the scraper plate gradually pushes the scraped scale into the liquid inlet square tube. When the scraped scale needs to be discharged, the control system starts the gate valve, and the gate valve opens the bottom of the liquid inlet square tube. The cooling water between the scraper plate abutting the block and the end of the condensation tank body discharges the scale accumulated in the liquid inlet square tube, thereby achieving the cleaning of the scraped scale.

[0014] Optionally, a plurality of wear-resistant sleeves are provided on the scraper plate, the wear-resistant sleeves correspond to the condenser tubes one-to-one, the wear-resistant sleeves are coaxially sleeved on the condenser tubes, and the circumferential inner wall of the wear-resistant sleeves is in close contact with the circumferential outer wall of the condenser tubes.

[0015] By adopting the above technical solution, the wear-resistant sleeve reduces the wear of the scraper plate by scale, which is beneficial to increasing the service life of the scraper plate and at the same time improves the sealing performance of the cooling water between the scraper plate and the condenser tube.

[0016] Optionally, the wear-resistant sleeve is rotatably arranged on the scraper plate, a spiral groove is provided on the outer wall of the condenser along its axial direction, a protrusion is provided on the wear-resistant sleeve, and the protrusion slides in cooperation with the spiral groove, and scraper tubes are coaxially provided at both ends of the wear-resistant sleeve, and a plurality of scrapers are evenly arranged on the scraper tube along its axial circumference, and the scrapers are attached to the outer wall of the condenser.

[0017] By adopting the above technical solution, under the restrictive action of the spiral groove and the protrusion, the wear-resistant sleeve will rotate during the sliding process of the scraper plate. The rotating wear-resistant sleeve drives the scraper on the scraper tube to continuously scrape off the scale accumulated on the condenser tube, which is beneficial to improve the scale cleaning effect and maintain the smooth sliding of the scraper plate.

[0018] Optionally, the scraper is arranged circumferentially and tilted along the axis of the scraper tube, and the scrapers at both ends of the wear-resistant sleeve are tilted in opposite directions.

[0019] By adopting the above technical solution, when the scraper plate slides in the reverse direction, the scraper can still scrape off the scale on the condenser tube.

[0020] Optionally, the cross-section of the liquid inlet square tube is much larger than the cross-section of the cooling supply tube.

[0021] By adopting the above technical solution, the scale scraped off can be accumulated in the liquid inlet square tube as much as possible.

[0022] Optionally, when the scraper plate abuts against the block, the scraper plate is close to the liquid inlet square tube.

[0023] By adopting the above technical solution, the amount of scale scraped off and remaining on the bottom wall of the condensation tank is reduced.

[0024] Optionally, a sealing rubber ring is provided between the cover shell and the condensation tank body.

[0025] By adopting the above technical solution, the sealing between the cover shell and the condensation tank body is improved.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Workers introduce cooling water into the water inlet pipe, which is then injected into the condenser tank and flows out from the water outlet pipe. At the same time, the refrigerant in the chiller flows into the inlet chamber through the hot mass pipe, then flows into the other end housing through the condenser pipe connected to the inlet chamber, and then flows back to the outlet chamber through the condenser pipe connected to the outlet chamber, and then flows back to the chiller through the cold mass pipe, thereby cooling the refrigerant. At the same time, the drive assembly drives the scraper to slide, and the scale formed on the condenser pipe falls to the inner bottom wall of the condenser tank. Finally, the scale removed is discharged from the condenser tank by the scale removal component, thereby solving the cooling effect of the scale formed on the condenser pipe on the refrigerant. 2. The worker starts the first solenoid valve at one end of the condensing tank and closes the second solenoid valve through the control system. At the same time, he starts the second solenoid valve at the other end of the condensing tank and closes the first solenoid valve. The cooling water flowing in from the water inlet pipe flows into the end of the condensing tank along the cooling pipe, the first solenoid valve and the liquid inlet square pipe of the opened first solenoid valve in this order. The cooling water flowing into the condensing tank pushes the scraper plate to slide. The scraper plate scrapes off the scale on the condensing tube in the process of sliding along the axis of the condensing tank. The cooling water on the side where the scraper plate opens the second solenoid valve flows out along the liquid outlet pipe, the heat exhaust pipe, the second solenoid valve and the water outlet pipe of the opened second solenoid valve in this order until the scraper plate abuts the block. At this time, the cooling water flowing in from the water inlet pipe flows out from the liquid outlet pipe on the side where the scraper plate faces away from the block, thereby completing the removal of the scale on the condensing tube. 3. When the scraper plate passes over the liquid outlet pipe and approaches the block, the scraper plate continuously squeezes the cooling water between the end of the condenser tank and the block. The squeezed cooling water flows through the one-way valve to the heat exhaust pipe, thereby relieving the liquid pressure between the end of the condenser tank and the block.

[0032] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0033] The embodiment of the present application discloses a condensing device for a chiller.

[0034] Reference Figure 1 A condensing device for a chiller includes a chiller 1 and a condensing tank body 2. The condensing tank body 2 is placed horizontally, two support plates 22 are welded to the bottom of the condensing tank body 2, and a water inlet pipe 3 and a water outlet pipe 4 are arranged on the condensing tank body 2.

[0035] Reference Figure 2 Several condensing tubes 5 are arranged in the condensing tank body 2. The axis of the condensing tube 5 is parallel to the axis of the condensing tank body 2. The two ends of the condensing tube 5 pass through the two ends of the condensing tank body 2 respectively. Both ends of the condensing tank body 2 are coaxially bolted with a cover shell 6. A sealing rubber ring 21 is arranged between the cover shell 6 and the condensing tank body 2. The sealing rubber ring 21 can be made of rubber material. The ends of the condensing tubes 5 on the same end of the condensing tank body 2 are both in the cover shell 6.

[0036] Reference Figure 2A partition 7 is welded between one of the cover shells 6 and the end of the condensation tank body 2. The partition 7 abuts against the end of the condensation tank body 2. The partition 7 divides the space inside the cover shell 6 into a mass inlet chamber 8 and a mass outlet chamber 9. A hot mass pipe 10 is connected between the mass inlet chamber 8 of the cover shell 6 and the chiller 1, and a cold mass pipe 11 is connected between the mass outlet chamber 9 of the cover shell 6 and the chiller 1.

[0037] The heat-absorbing refrigerant in the chiller 1 flows into the inlet chamber 8 through the hot mass pipe 10, then flows into the cover 6 at the other end through the condenser pipe 5 connected to the inlet chamber 8, and then flows back to the outlet chamber 9 through the condenser pipe 5 connected to the outlet chamber 9, and finally flows back to the chiller 1 through the cold mass pipe 11. During this process, cooling water flows in from the water inlet pipe 3 at the bottom of the condensation tank body 2, and then flows out from the water inlet pipe 3 at the top of the condensation tank body 2, thereby cooling the refrigerant flowing through the condenser pipe 5.

[0038] Reference Figure 2 、 Figure 3 and Figure 4 A scraper plate 12 is coaxially slidably arranged in the condensation tank body 2. The scraper plate 12 is slidably sleeved on the condensation tube 5. The circumferential outer wall of the scraper plate 12 is in close contact with the circumferential inner wall of the condensation tank body 2. A driving component 13 and a scale discharge component 14 are arranged on the condensation tank body 2. The driving component 13 is used to drive the scraper plate 12 to slide, and the scale discharge component 14 is used to discharge the scale scraped off from the condensation tank body 2.

[0039] Reference Figure 1 and Figure 2 The driving assembly 13 includes a liquid inlet square tube 131 and a liquid outlet pipe 132 welded to both ends of the condensation tank body 2. The cross-section of the liquid inlet square tube 131 is much larger than the cross-section of the cooling pipe 133. The liquid outlet pipe 132 is located above the liquid inlet square tube 131. The liquid inlet square tube 131 and the liquid outlet pipe 132 on the same end of the condensation tank body 2, the distance between the liquid inlet square tube 131 and the end of the condensation tank body 2 is smaller than the distance between the liquid outlet pipe 132 and the end of the condensation tank body 2.

[0040] Reference Figure 1 and Figure 2 The distance between the liquid inlet square tube 131 and the liquid outlet tube 132 in the axial direction of the condensing tank body 2 is greater than the width of the scraper plate 12. A cooling pipe 133 is connected between the water inlet pipe 3 and the two liquid inlet square tubes 131 at both ends of the condensing tank body 2. The two cooling pipes 133 are bolted with a first solenoid valve 134 electrically connected to the control system. A heat exhaust pipe 135 is connected between the water outlet pipe 4 and the two liquid outlet tubes 132 at both ends of the condensing tank body 2.

[0041] Reference Figure 1 and Figure 2, a second solenoid valve 136 electrically connected to the control system is bolted to each of the two heat exhaust pipes 135 , and a plurality of blocks 137 are welded on the inner wall of the condensing tank body 2 between the liquid inlet square tube 131 and the liquid outlet pipe 132 on the same end of the condensing tank body 2 . The plurality of blocks 137 are evenly distributed circumferentially on the inner wall of the condensing tank body 2 , and the blocks 137 are used to abut the scraping plate 12 . When the scraping plate 12 abuts the blocks 137 , the scraping plate 12 is close to the liquid inlet square tube 131 .

[0042] Reference Figure 1 and Figure 2 A one-way valve 15 is connected between the heat exhaust pipe 135 between the condensation tank body 2 and the second solenoid valve 136 and the condensation tank body 2. The connection point between the one-way valve 15 and the condensation tank body 2 is located between the block 137 and the cover 6. The medium between the end of the condensation tank body 2 and the block 137 flows from the one-way valve 15 to the heat exhaust pipe 135.

[0043] Reference Figure 1 and Figure 2 The descaling component 14 includes a gate valve 141 welded to the bottom of the liquid inlet square tube 131 and electrically connected to the control system. The cooling pipe 133 is located between the gate valve 141 and the condensation tank body 2. The gate valve 141 is used to seal the bottom of the liquid inlet square tube 131.

[0044] When the scraper plate 12 in the condensation tank body 2 abuts against the block 137 at the end away from the partition 7, and the scale solidified on the condenser tube 5 needs to be cleaned, the control system starts the first solenoid valve 134 on the side close to the scraper plate 12 and closes the first solenoid valve 134 on the side away from the scraper plate 12, and at the same time closes the second solenoid valve 136 on the side close to the scraper plate 12 and starts the second solenoid valve 136 on the side away from the scraper plate 12.

[0045] The cooling water flowing in from the water inlet pipe 3 flows into the end of the condensation tank body 2 along the cooling pipe 133 with the first solenoid valve 134 opened, the first solenoid valve 134 and the liquid inlet square pipe 131 in this order. The hydraulic pressure between the scraper plate 12 and the end of the condensation tank body 2 increases, and then pushes the scraper plate 12 in the condensation tank body 2 to slide toward the end close to the partition 7, and the scraper plate 12 scrapes off the scale formed on the condensation tube 5.

[0046] The cooling water directed by the scraper plate 12 toward the side of the partition 7 flows out of the condensation tank body 2 along the liquid outlet pipe 132 on the side of the open second solenoid valve 136, the heat exhaust pipe 135, the second solenoid valve 136 and the water outlet pipe 4 in this order until the scraper plate 12 abuts against the block 137 close to the side of the partition 7. At the same time, the scraper plate 12 pushes the scraped scale into the liquid inlet square pipe 131 connected to the closed first solenoid valve 134.

[0047] When the scraper plate 12 passes over the liquid outlet pipe 132 and approaches the block 137, the scraper plate 12 continuously squeezes the cooling water between the end of the condensation tank body 2 and the block 137. The squeezed cooling water flows through the one-way valve 15 to the heat exhaust pipe 135. At the same time, the scraper plate 12 gradually pushes the scraped scale into the liquid inlet square pipe 131. At this time, the cooling water injected into the condensation tank body 2 is discharged from the liquid outlet pipe 132 on the side of the scraper plate 12 facing away from the block 137.

[0048] When the scraped scale needs to be discharged, the control system starts the gate valve 141 on the liquid inlet square tube 131 where the scale is accumulated. The gate valve 141 opens the bottom of the liquid inlet square tube 131, and the cooling water between the scraper plate 12 abutting the block 137 and the end of the condensation tank body 2 discharges the scale accumulated in the liquid inlet square tube 131.

[0049] Reference Figure 2 、 Figure 3 and Figure 4 The scraper plate 12 is assembled by welding multiple plates. A number of wear-resistant sleeves 16 are rotatably arranged on the scraper plate 12. The wear-resistant sleeves 16 correspond to the condenser tubes 5 one by one. The wear-resistant sleeves 16 are coaxially sleeved on the condenser tube 5. The circumferential inner wall of the wear-resistant sleeve 16 is tightly attached to the circumferential outer wall of the condenser tube 5. A spiral groove 17 is opened on the outer wall of the condenser tube 5 along its axial direction.

[0050] Reference Figure 2 、 Figure 3 and Figure 4 A protrusion 18 is welded on the wear-resistant sleeve 16, and the protrusion 18 slides with the spiral groove 17. A scraper tube 19 is coaxially welded at both ends of the wear-resistant sleeve 16. A plurality of scrapers 20 are evenly welded on the scraper tube 19 along its axis. The scrapers 20 are attached to the outer wall of the condenser tube 5. The scrapers 20 are arranged obliquely along the axis of the scraper tube 19. The scrapers 20 at both ends of the wear-resistant sleeve 16 are inclined in opposite directions.

[0051] During the sliding process of the scraper plate 12, under the restriction of the spiral groove 17 and the protrusion 18, the wear-resistant sleeve 16 will rotate. The rotating wear-resistant sleeve 16 drives the scraper 20 on the scraper tube 19 to continuously scrape off the scale accumulated on the condenser tube 5, thereby improving the scale cleaning effect.

[0052] The implementation principle of a condensing device for a chiller in an embodiment of the present application is as follows: the heat-absorbing refrigerant in the chiller 1 flows into the inlet chamber 8 through the hot mass pipe 10, then flows into the cover 6 at the other end through the condenser pipe 5 connected to the inlet chamber 8, and then flows back to the outlet chamber 9 through the condenser pipe 5 connected to the outlet chamber 9, and finally flows back to the chiller 1 through the cold mass pipe 11. During this process, cooling water flows in through the water inlet pipe 3 at the bottom of the condensation tank body 2, and then flows out through the water inlet pipe 3 at the top of the condensation tank body 2, thereby cooling the refrigerant flowing through the condenser pipe 5.

[0053] When the scraper plate 12 in the condensation tank body 2 abuts against the block 137 at the end away from the partition 7, and the scale solidified on the condenser tube 5 needs to be cleaned, the control system starts the first solenoid valve 134 on the side close to the scraper plate 12 and closes the first solenoid valve 134 on the side away from the scraper plate 12, and at the same time closes the second solenoid valve 136 on the side close to the scraper plate 12 and starts the second solenoid valve 136 on the side away from the scraper plate 12.

[0054] The cooling water flowing in from the water inlet pipe 3 flows into the end of the condensation tank body 2 along the cooling pipe 133 with the first solenoid valve 134 opened, the first solenoid valve 134 and the liquid inlet square pipe 131 in this order. The hydraulic pressure between the scraper plate 12 and the end of the condensation tank body 2 increases, and then pushes the scraper plate 12 in the condensation tank body 2 to slide toward the end close to the partition 7, and the scraper plate 12 scrapes off the scale formed on the condensation tube 5.

[0055] The cooling water directed by the scraper plate 12 toward the side of the partition 7 flows out of the condensation tank body 2 along the liquid outlet pipe 132 on the side of the open second solenoid valve 136, the heat exhaust pipe 135, the second solenoid valve 136 and the water outlet pipe 4 in this order until the scraper plate 12 abuts against the block 137 close to the side of the partition 7. At the same time, the scraper plate 12 pushes the scraped scale into the liquid inlet square pipe 131 connected to the closed first solenoid valve 134.

[0056] When the scraper plate 12 passes over the liquid outlet pipe 132 and approaches the block 137, the scraper plate 12 continuously squeezes the cooling water between the end of the condensation tank body 2 and the block 137. The squeezed cooling water flows through the one-way valve 15 to the heat exhaust pipe 135. At the same time, the scraper plate 12 gradually pushes the scraped scale into the liquid inlet square pipe 131. At this time, the cooling water injected into the condensation tank body 2 is discharged from the liquid outlet pipe 132 on the side of the scraper plate 12 facing away from the block 137.

[0057] When the scraped scale needs to be discharged, the control system starts the gate valve 141 on the liquid inlet square tube 131 where the scale is accumulated. The gate valve 141 opens the bottom of the liquid inlet square tube 131, and the cooling water between the scraper plate 12 abutting the block 137 and the end of the condensation tank body 2 discharges the scale accumulated in the liquid inlet square tube 131.

[0058] During the sliding process of the scraper plate 12, under the restriction of the spiral groove 17 and the protrusion 18, the wear-resistant sleeve 16 will rotate. The rotating wear-resistant sleeve 16 drives the scraper 20 on the scraper tube 19 to continuously scrape off the scale accumulated on the condenser tube 5, thereby improving the scale cleaning effect.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
