Description

Technical Field

[0001] The invention relates to the technical field of compressors, in particular to a two-stage water ring compressor with low moisture output. Background Art

[0002] Two-stage water ring compressor is a common positive displacement compressor, mainly used for gas compression, air extraction and vacuum generation. Two-stage water ring compressor consists of two main compression stages: the first stage and the second stage. Each compression stage has a rotor, a stator and a water ring. The water ring is usually composed of water. A closed annular space is formed inside the compressor by the rotating rotor. During the compression process, the gas contacts the water ring and is compressed through volume changes. Through the step-by-step compression of the two compression stages, a higher final pressure can be achieved.

[0003] A Chinese patent with announcement number CN106150980B discloses an air compressor including a base and a main engine and a cooler system arranged on the base. The invention uses water cooling to cool the cylinder, ensuring that the oil-free ring works at an almost constant temperature. The closed balance chamber structure of the compressor is simpler and more compact.

[0004] A Chinese patent with announcement number CN112177950B discloses a circulating centrifugal gas compressor, including a gas compressor housing, a waterproof fixed base and a hollow telescopic housing. The invention is provided with a vacuum chamber, which is used in conjunction with a vacuum pump to evacuate the gas before use to ensure the purity of the compressed gas. The multi-chamber filter box and the lifting top plate can filter different gases during compression to meet more usage requirements.

[0005] In the above and similar prior arts, the compressed air discharged from the two-stage water ring compressor will contain a certain amount of moisture, especially when the cooling effect is poor or the humidity of the gas itself is high, which greatly increases the water content in the compressed gas. The moisture in the compressed gas will accumulate in pipelines, valves, control equipment, air tools and other downstream equipment, causing corrosion of metal parts. In some precise processes or production processes, it will affect the quality of the product or cause precision errors in the equipment, resulting in unqualified production or damage to the product. At the same time, the water in the water ring will affect the stability of the water ring itself as the gas is discharged. Excessive water discharge will cause the water ring system to be frequently drained and replenished, thereby increasing the maintenance workload and may have an adverse effect on the operating efficiency of the compressor.

[0006] Therefore, the present invention provides a two-stage water ring compressor with low water output, which can reduce the water content in the discharged compressed gas and condense the water to supplement the water ring itself. Summary of the invention

[0019] (3) The two-stage water ring compressor with low moisture output described in the present invention adopts a reflux design of the connecting pipe, so that condensed water can enter the water ring for reuse. At the same time, due to the low temperature of the condensed water, after being integrated into the water ring, it can reduce the working temperature of the machine body and the temperature of the water ring.

[0030] In this embodiment, a reduction mechanism 13 is provided inside the large gear box 6. The reduction mechanism 13 is configured to realize a first-stage speed reduction transmission through the meshing of a worm wheel 136 and a worm sleeve 14, and realize a second-stage speed reduction transmission through a pinion 135. The reduction mechanism 13 is connected to the spiral mechanism 12 in a transmission manner to realize the rotation of the spiral mechanism 12 in the cooling pipe 11. The reduction mechanism 13 includes a transmission rod 134. A worm wheel 136 is fixedly installed on the outer side of the transmission rod 134. A pinion 135 is fixedly installed on the outer side of the transmission rod 134, and the pinion 135 is located at the top of the worm wheel 136. A worm sleeve 14 is fixedly installed on the outer side of the rotating shaft 2, and the worm sleeve 14 meshes with the worm wheel 136. The reduction mechanism 13 It also includes a short shaft 131, which is rotatably installed inside the partition 9 through a bearing, one end of the short shaft 131 is installed on the inner side of the top wall of the quarter box 8 through a bearing, a large bevel gear 132 is fixedly installed on the outer side of the short shaft 131, and the large bevel gear 132 is located at the top of the partition 9, and the large bevel gear 132 is respectively meshed with multiple small bevel gears 122, and a large gear 133 is fixedly installed on the other end of the short shaft 131, and the large gear 133 is located at the bottom of the partition 9, a transmission rod 134 is installed inside the bearing cover 3 near the water inlet 4 through a bearing, and one end of the transmission rod 134 is installed through a bearing through the bottom of the small gear box 7, and the small gear 135 is located on the inner side of the small gear box 7 and meshes with the large gear 133.

[0031] Specifically, the bearing cover 3 and the small gear box 7 can provide rotation support for the transmission rod 134 through the bearing, the transmission rod 134 can provide rotation support for the small gear 135 and the worm wheel 136, the rotating shaft 2 can provide a stable support for the grip sleeve, and the worm sleeve 14 can provide meshing for the worm wheel 136. When the rotating shaft 2 drives the worm sleeve 14 to rotate, the worm sleeve 14 drives the worm wheel 136 to rotate by meshing with the worm wheel 136, and the worm wheel 136 drives the small gear 135 to rotate through the transmission rod 134. The partition plate 9 can provide rotation support for the short shaft 131, and the short shaft 131 can provide rotation support for the large bevel gear 132 and the large gear 133.

Since the rotating shaft 2 rotates too fast when working, and the required rotation speed of the spiral plate 124 is relatively small, the spiral plate 124 can reach the required rotation speed through the first-stage speed reduction transmission of the worm wheel 136 and the worm sleeve 14 and the second-stage speed reduction transmission of the small gear 135 and the large gear 133.

[0032] In this embodiment, air outlet ducts 18 are respectively installed through the tops of the plurality of cooling tubes 11, and a centralizing box 19 is fixedly installed at one end of the air outlet duct 18 away from the cooling tube 11. The centralizing box 19 is located at the top of the refrigerator 15, and an exhaust valve 20 is installed through the top of the centralizing box 19, and the centralizing box 19 is communicated with the air outlet duct 18.

[0033] Specifically, the cooling pipe 11 can provide a stable support for the air outlet pipe 18, the air outlet pipe 18 can provide a transportation channel for the condensed compressed air, and the concentration box 19 can provide a storage space for the compressed air, so that the compressed gas divided into four equal parts can be gathered again on the inner side of the concentration box 19, and then discharged through the exhaust valve 20.

[0034] In this embodiment, a leakage pipe 21 is installed through the bottom of the air outlet pipe 18, the bottom of the leakage pipe 21 is connected to a central pipe 22, the bottom of the central pipe 22 is connected to a water outlet pipe 23, one end of a connecting pipe 24 is fixedly installed on the outer side of the water outlet pipe 23, a one-way valve 25 is fixedly installed on the other end of the connecting pipe 24, and the one-way valve 25 is connected to the channel of the water inlet 4.

[0035] Specifically, the leaking pipe 21 can provide an outflow channel for the condensed water in the cooling pipe 11, so that the condensed water in the four cooling pipes 11 enters the collecting pipe 22 through the leaking pipe 21 respectively, and is transported back to the inner side of the body 1 through the outlet pipe 23 and the connecting pipe 24. The one-way valve 25 can withstand a higher pressure difference, such as a high-pressure spring-type one-way valve 25 or an automatic sealing one-way valve 25. These valves are designed to withstand a large pressure from the water inlet 4, while still ensuring that the condensed water flows in only one direction, so that the condensed water flows back to the inner side of the body 1 and enters the water ring again for utilization. Due to the low temperature of the condensed water, after being integrated into the water ring, the operating temperature of the body 1 can be reduced, and the temperature of the water ring can be reduced at the same time. The reduction in the temperature of the water ring can reduce the evaporation of water into the compressed air, thereby reducing the moisture in the gas discharged through the air outlet valve, thereby achieving a virtuous cycle of reducing the moisture in the compressed gas.

[0036] Working principle: the staff first energizes the refrigerator 15 to make the refrigerator 15 work and lower the temperature of the cooling jacket 17 through the connecting rod 16, and then uses an external driving device to drive the rotating shaft 2 to rotate, so that the body 1 works to compress the gas, and the compressed gas is discharged into the inner side of the quarter box 8 through the air outlet valve and the connecting valve 5, so that the gas inside the quarter box 8 passes through the ventilation hole 10 and enters the inner side of the cooling pipe 11. The quarter box 8 divides the compressed gas into four equal parts, so that the equally divided gas enters the four cooling pipes 11 respectively for separate cooling, and the compressed gas entering the cooling pipe 11 flows along the gap between the hollow pipe 123 and the cooling pipe 11, and spirals away under the guidance of the spiral plate 124. Move away from the quarter box 8, the temperature of the cooling tube 11 is reduced under the cooling effect of the cooling jacket 17, and the cooled cooling tube 11 cools the gas, thereby condensing small water droplets, reducing the moisture in the compressed gas, and because the hollow tube 123 reduces the width of the gap between the cooling tube 11 and the hollow tube 123, the gas can be close to the inner wall of the cooling tube 11 when passing through the gap, thereby increasing the contact frequency between the compressed gas and the cooling tube 11, and the spiral plate 124 increases the condensation time of the compressed gas, improves the condensation effect, and makes the compressed gas fully dry, and the dried compressed gas enters the central box 19 through the outlet pipe 18, so that the compressed gas in the four cooling tubes 11 is combined with the concentrated box 19 and discharged together through the exhaust valve 20; When the rotating shaft 2 rotates, the outer worm sleeve 14 is driven to rotate, so that the worm sleeve 14 drives the worm wheel 136 to rotate by meshing with the worm wheel 136, and the worm wheel 136 drives the small gear 135 to rotate through the transmission rod 134, so that the small gear 135 drives the short shaft 131 to rotate by meshing with the large gear 133, and the short shaft 131 drives the large bevel gear 132 to rotate, so that the large bevel gear 132 drives the small bevel gear 122 to rotate by meshing with the four small bevel gears 122, and then drives the rotating rod 121 to rotate, so that the rotating rod 121 drives the hollow tube 123 and the spiral plate 1 24 rotation, because the meshing transmission between the worm wheel 136 and the worm sleeve 14 is a speed reduction transmission, the meshing transmission between the worm wheel 136 and the worm sleeve 14 can make the rotating shaft 2 transmit a lower rotation speed to the transmission rod 134, and at the same time, the transmission between the small gear 135 and the large gear 133 is also a speed reduction transmission, which can make the transmission rod 134 transmit a lower rotation speed to the short shaft 131 again. Under the secondary speed reduction effect, the short shaft 131 drives the large bevel gear 132 to rotate at a low speed, so that the meshing transmission between the large bevel gear 132 and the small bevel gear 122 drives the rotating rod 121 to rotate at a low speed; When the rotating rod 121 rotates at a low speed, it can drive the hollow tube 123 and the spiral plate 124 to rotate at a low speed, and the spiral plate 124 drives the sealing strip 125 to rotate in contact with the inner wall of the cooling tube 11, so that the sealing strip 125 scrapes off the condensed water on the inner wall of the cooling tube 11, so that the condensed water gathers on the inner side of the bottom wall of the cooling tube 11 under the action of gravity, and moves away from the quarter box 8 under the action of rotation, preventing the condensed water from adhering to the inner wall of the cooling tube 11 to block the direct contact between the compressed air and the inner wall of the cooling tube 11, thereby preventing the condensed water from reducing the condensation effect of the cooling tube 11 on the compressed air, and indirectly improving the condensation effect of the cooling tube 11 on the compressed air; Under the action of the spiral plate 124, the condensed water moves to the position of the leakage pipe 21, and flows through the leakage pipe 21 to the inner side of the central pipe 22. The condensed water in the four cooling rods gathers in the central pipe 22, and returns to the inner side of the machine body 1 along the outlet pipe 23 and the connecting pipe 24, so that the condensed water enters the water ring for reuse. At the same time, due to the low temperature of the condensed water, after being integrated into the water ring, it can reduce the working temperature of the machine body 1 and the temperature of the water ring. The reduction in the temperature of the water ring can reduce the evaporation of water and dissolve into the compressed air, thereby reducing the moisture in the gas discharged through the air outlet valve, thereby realizing a virtuous cycle of reducing the moisture in the compressed gas.
