Description

Technical Field

[0001] The invention relates to the technical field of vacuum pumps, in particular to air-water separation equipment for vacuum pumps. Background Art

[0002] The existing liquid ring vacuum pump uses an impeller that is eccentric to the pump housing. A certain amount of water is filled in the pump housing. The impeller rotates to form a water ring. When adjacent blades rotate, the space (air chamber) formed with the water ring becomes larger, that is, air is taken in. The space (air chamber) gradually becomes smaller, that is, the air is compressed. Multiple groups of adjacent blades, that is, multiple groups of reciprocating compression. During the operation of the liquid ring vacuum pump, due to the continuous rotation of the impeller, a large amount of heat will be generated, and long-term operation is easy to cause damage to the pump body.

[0003] The existing heat dissipation method is to add a gas-liquid separation device after the vacuum pump, but some companies' separation devices use sedimentation separation, which uses the density difference between gas and liquid. The gas rises and the liquid sinks. In the gravity field, the gas with lower density will float above the liquid and be separated by the separator. A large amount of water will be separated from the gas in the gas-liquid separator, but at the pipe end of the exhaust pipe there will still be a part of the remaining water vapor carried by the gas, which cannot be separated cleanly and enters the air, causing environmental pollution and waste of resources.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] 1. In the present invention, the entire discharge pipe is covered by a water-absorbing sponge, which can effectively absorb the moisture passing through the gas, preventing excess gaps from causing the gas to carry moisture and directly overflow, causing the gas-water separation to fail and affecting the external environment, thereby ensuring the overall gas-water separation efficiency of the equipment.

[0017] 2. In the present invention, the guide leaf can be driven to rotate when the airflow circulates, so that the pressing roller rotates from the upper and lower sides to press out the liquid inside the water-absorbing sponge, thereby ensuring the overall dryness of the water-absorbing sponge, so that it always has efficient water absorption performance, and as the rotation speed of the guide leaf becomes faster, the guide leaf will move upward as a whole due to the lift, and cooperate with the telescopic component to drive the pressing roller at the bottom to move upward, while the height of the pressing roller above remains unchanged, thereby increasing the pressing force of the two on the water-absorbing sponge, improving its water pressing efficiency, and achieving the function of adaptive water removal.

[0018] 3. In the present invention, a sealing ring is used to limit the rotation of the water storage pressure roller, and the double-sided bevel gear ring can be used to ensure that the upper and lower water storage pressure rollers always maintain the same rotation position, so that the positions of the water inlet grooves correspond to each other to complete the removal of water from the water-absorbing sponge at the squeezing point, and prevent the water inside the water storage pressure roller from overflowing and falling back into the water-absorbing sponge when rolling. In addition, the centrifugal force of rotation is used to drive the water inside the water storage pressure roller to flow into the liquid guide groove and finally out of the connecting pipe, thereby achieving the purpose of gas-liquid separation.

[0019] 4. The gas is discharged to the steam-water separator through the exhaust pipe by the vacuum pump. Due to the action of the steam-water separator, the gas is discharged and the liquid will flow back to the circulating water tank at the same time, and dissipate the heat of the vacuum pump liquid. When the liquid level in the system is too low or the temperature is too high, the liquid level meter, thermometer and electronic control system will automatically control the system to continuously add cooling water to cool the circulating water. When the liquid level is too high, the drain port will automatically open to discharge the hot water in the circulating water tank, so as to continuously maintain the temperature and water level of the circulating water in the circulating water tank at the appropriate working conditions, avoid the vacuum degree drop caused by lack of water and temperature increase of the vacuum pump, and improve the working efficiency of the overall equipment.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] In the prior art, during the operation of the water ring vacuum pump 1, a large amount of heat is generated due to the continuous rotation of the impeller, and long-term operation is likely to cause damage to the pump body. The gas-liquid separator used is often unable to effectively remove the water in the gas, resulting in a decrease in the working efficiency of the separator. It also affects the heat dissipation and water circulation of the vacuum pump, reducing the working efficiency of the overall equipment.

[0034] The purpose of the present invention is at least to effectively solve the problem of heat accumulation inside the water ring vacuum pump 1 through the gas-liquid separator, and to further improve the gas-liquid separation effect by adding a water removal device at the outlet end of the gas-water separator 3, thereby ensuring the volatilization of heat and the recycling of water, and greatly improving the working efficiency of the overall equipment.

[0035] Embodiment, according to Figure 1 - Fig. 9 ,like Figure 1 As shown, the vacuum pump gas-water separation equipment comprises a water ring vacuum pump 1, one end of the water ring vacuum pump 1 is fixedly connected with an air suction pipeline 8 and an exhaust pipeline 9, the other end of the exhaust pipeline 9 is fixedly connected with a steam-water separator 3, a circulating water tank 2 is arranged at the bottom end of the steam-water separator 3, an automatic water replenishment valve 4 is arranged on one side of the top of the circulating water tank 2 and located on the right side of the steam-water separator 3, a liquid level gauge 5 is arranged inside the circulating water tank 2, a thermometer 6 is fixedly installed below the liquid level gauge 5 and located on the right side of the circulating water tank 2, a sewage outlet 7 is fixedly installed at the bottom end of the right side of the circulating water tank 2, a discharge box 10 is fixedly installed at the top of the steam-water separator 3, a discharge pipe 11 is fixedly connected to the top of the discharge box 10, a double-sided bevel gear ring 12 is fixedly installed at the bottom end of the inside of the discharge pipe 11, and the double-sided bevel gear ring 12 is fixedly installed inside the double-sided bevel gear ring 12. A water-absorbing sponge 13 is fixedly installed on the side, and the steam-water separator 3 is located on the top of the circulating water tank 2. The gas is discharged to the steam-water separator 3 through the exhaust pipe 9 through the water ring vacuum pump 1. Because of the action of the steam-water separator 3, the gas is discharged at the same time, and the liquid will flow back into the circulating water tank 2 and dissipate the heat of the liquid in the water ring vacuum pump 1. When the liquid level in the system is too low or the temperature is too high, the liquid level meter 5, the thermometer 6 and the automatic control of the electronic control system will continuously replenish cooling water into the system to cool the circulating water. When the liquid level is too high, the drain port 7 will automatically open to discharge the hot water in the circulating water tank 2, so as to continuously maintain the temperature and water level of the circulating water in the circulating water tank 2 at a suitable working condition, and avoid the vacuum degree of the vacuum pump from decreasing due to lack of water and increased temperature.

[0036] like Figure 2In the embodiment, an S-shaped channel 101 is provided inside the discharge box 10, and the bottom end of the S-shaped channel 101 is connected to the top outlet of the gas-water separator 3, and a liquid guide groove 102 is provided inside the discharge box 10, and a liquid guide ring 103 is fixedly connected to the top of the liquid guide groove 102, and a liquid guide pipe 104 is fixedly connected to the top of the liquid guide ring 103, and the liquid guide pipe 104 and the liquid guide ring 103 are used to divert and guide the liquid in the gas-liquid separation, thereby improving the liquid discharge speed in the gas-liquid separation.

[0037] like Figure 2 In the embodiment, the bottom end of the liquid guide groove 102 is fixedly connected with a connecting pipe 105, and the bottom end of the connecting pipe 105 is directly connected with the circulating water tank 2. The liquid inside the connecting pipe 105 is collected and enters the circulating water tank 2 to complete the liquid collection, thereby improving the overall environmental protection performance of the device;

[0038] like Figure 4 and Figure 5 In the embodiment, a connecting rod 14 is fixedly installed in the middle of the water-absorbing sponge 13, a connecting platform 15 is fixedly installed on the top of the connecting rod 14, and a guide leaf 16 is fixedly installed on the side of the connecting platform 15. The guide leaf 16 is driven to rotate in coordination with the flow of air, and kinetic energy is provided by the air flow itself, thereby improving the overall environmental protection of the device, and the height can be changed according to the flow rate of the air flow to form different pressing effects, thereby further improving the applicability of the device;

[0039] like Figure 3 In the embodiment, a drainage groove 1101 is provided inside the discharge pipe 11, and the bottom end of the drainage groove 1101 and the top end of the liquid guiding tube 104 are connected to each other. A mounting groove 1102 is provided inside the discharge pipe 11, and the mounting groove 1102 can provide a function of fixing and installing the double-sided bevel gear ring 12, and can also provide installation positions for the upper and lower pressing rollers, especially the upper pressing roller has a limiting function, so that its height position cannot be moved, thereby improving the overall pressing effect;

[0040] like Figure 5 In the embodiment, a telescopic assembly 18 is fixedly mounted on the outer side of the bottom end of the connecting rod 14, and a pressing assembly 17 is movably sleeved on the bottom end of the guide leaf 16;

[0041] like Figure 6 In the embodiment, the pressing assembly 17 includes a sealing ring 1701, a top of the sealing ring 1701 is fixedly installed with an oblique guide rod 1702, the oblique guide rod 1702 and the guide leaf 16 are movably connected to each other, a water storage pressure roller 1703 is rotatably installed inside the sealing ring 1701, the outer end of the water storage pressure roller 1703 is fixedly connected with a bevel gear 1704, the outer end of the bevel gear 1704 is fixedly connected with a limited position convex pipe 1705, and a water inlet groove 1706 is provided on the surface of the water storage pressure roller 1703. The oblique guide rod 1702 can effectively ensure that the sealing ring 1701 and the guide leaf 16 are linked as a whole, so that they can achieve the purpose of synchronous movement;

[0042] like Figure 7 and Fig. 9 In the embodiment, the surface of the bevel gear 1704 and the surface of the double-sided bevel gear ring 12 are meshed with each other, the limiting convex tube 1705 is slidably installed inside the discharge pipe 11, and its port is communicated with the drainage groove 1101. The bevel gear 1704 is meshed with the inner wall of the double-sided bevel gear ring 12, so that the position of the water inlet groove 1706 inside the upper and lower pressing rollers can always remain corresponding when it moves, so that it can be pressed to the position of the water-absorbing sponge 13. At that time, the liquid at this position of the water-absorbing sponge 13 enters the water storage roller 1703 from the water inlet groove 1706 to complete the water storage operation, and then the water body is made to flow out from the port of the limiting convex tube 1705 and enter the drainage groove 1101 to complete the final collection by rotating centrifugation;

[0043] like Figure 8 In the embodiment, the telescopic assembly 18 includes a fixed rod 1801, a spring 1802 is fixedly connected inside the fixed rod 1801, a synchronization rod 1803 is fixedly connected to the outer end of the spring 1802, and the synchronization rod 1803 is movably sleeved inside the fixed rod 1801. The synchronization rod 1803 can be telescoped so that the bevel gear 1704 outside the lamination roller connected thereto can always fit on the inner side of the double-sided bevel gear ring 12 to complete the meshing, and as the position of the bevel gear 1704 rises, it can automatically retract inward to prevent the height from changing and the bevel fitting size from changing, resulting in a failure to mesh, thereby ensuring the synchronous rotation of the upper and lower lamination rollers and improving the water removal efficiency;

[0044] like Figure 6 Neutralization Figure 7 The sealing ring 1701, the water storage pressure roller 1703 and the bevel gear 1704 together constitute a pressing roller, which is distributed on the upper and lower sides of the water-absorbing sponge 13, and the sealing ring 1701 inside the pressing roller on the lower side of the water-absorbing sponge 13 is fixedly connected to the outer end of the synchronization rod 1803, and the two pressing rollers are symmetrically distributed up and down. Through the symmetrically distributed pressing rollers, when the water-absorbing sponge 13 is squeezed out of the water, the water body is directly splashed from the inside of the water inlet groove 1706 into the inside of the water storage pressure roller 1703, and the external protection of the sealing ring 1701 prevents the water body from overflowing to the outside while the water storage pressure roller 1703 rotates, so that it can only enter the inside of the limiting convex pipe 1705 through the centrifugal force of the revolution and finally be discharged into the inside of the drainage groove 1101.

[0045] In this embodiment, the water ring vacuum pump 1 is located outside the circulating water tank 2, and the impeller is eccentric to the pump housing. A certain amount of water is filled in the pump housing, and the impeller rotates to form a water ring. When the adjacent blades rotate, the space (air chamber) formed with the water ring becomes larger, that is, air is taken in, and the space (air chamber) gradually becomes smaller, that is, the air is compressed by multiple groups of adjacent blades, that is, multiple groups of reciprocating compression, and the vacuuming process is continuously performed on the vacuum equipment through the suction pipeline 8, and then the system gas is discharged through the exhaust pipeline 9. After a certain working time, a vacuum state is gradually formed.The circulating water tank 2 is located outside the water ring vacuum pump 1 and is used to store the liquid water required by the water ring vacuum pump 1. The steam-water separator 3 is located on the top of the circulating water tank 2. The gas is discharged to the steam-water separator 3 through the exhaust pipe 9 through the water ring vacuum pump 1. Because of the action of the steam-water separator 3, the liquid will flow back into the circulating water tank 2 while the gas is discharged, and the heat of the liquid in the water ring vacuum pump 1 will be dissipated. When the liquid level in the system is too low or the temperature is too high, the liquid level meter 5, the thermometer 6 and the automatic control of the electronic control system will continuously add cooling water into the system to cool the circulating water. When the liquid level is too high, the sewage outlet 7 will be automatically opened to cool the circulating water. The hot water in the water tank 2 is discharged to continuously maintain the temperature and water level of the circulating water in the circulating water tank 2 at a suitable working condition, so as to avoid the vacuum degree of the vacuum pump decreasing due to water shortage and temperature rise. The gas-water separator 3 separates the gas and liquid. After the separation, there is still less liquid left in the gas, which enters the inside of the S-shaped channel 101 and then enters the inside of the discharge pipe 11. When passing through the water-absorbing sponge 13, the gas and liquid are further separated. The gas passes through the diversion flow from the inside of the guide leaf 16, driving the guide leaf 16 to rotate. The guide leaf 16 drives the connecting platform 15 as a whole, so that the telescopic component 18 drives the pressing roller at the bottom to rotate. The guide leaf 16 is driven by The oblique guide rod 1702 drives the sealing ring 1701 to rotate as a whole. During the rotation, each time the bottom curved surface of the water storage pressure roller 1703 passes through the surface of the water-absorbing sponge 13, when the water inlet grooves 1706 on the upper and lower sides correspond to the upper position, the water inside the water-absorbing sponge 13 is squeezed into the water storage pressure roller 1703. Since the water storage pressure roller 1703 itself rotates horizontally with the rotation of the guide leaf 16, centrifugal force is generated. The centrifugal force drives the water flow inside the water storage pressure roller 1703 to flow out from the limiting convex pipe 1705, enter the interior of the drainage groove 1101, and gather from the liquid guide pipe 104, and finally enter the circulation through the connecting pipe 105. Inside the water tank 2, when the internal gas flow rate becomes larger, the rotation speed of the guide leaf 16 increases, and the guide leaf 16 itself moves upward due to the lift force. The water storage pressure roller 1703 located above is limited by the limiting convex tube 1705 as a whole, and its height remains unchanged. The water storage pressure roller 1703 at the bottom moves upward due to its relatively fixed connection with the connecting rod 14, and is affected by the meshing of the double-sided bevel gear ring 12. The synchronization rod 1803 automatically contracts inwardly. At the same time, the position of the water storage pressure roller 1703 at the bottom of the water-absorbing sponge 13 moves upward, forming a pressurization effect with the stationary water storage pressure roller 1703 at the upper end, thereby increasing the surface pressure on the water-absorbing sponge 13 and improving the water removal effect.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
