Description

Technical Field

[0001] This invention belongs to the field of delivery pump technology, specifically a piston-type high-pressure, high-flow gas-liquid delivery pump and a mixed delivery system. Background Technology

[0002] Piston-type high-pressure, high-flow gas-liquid transfer pumps rely on the positive displacement reciprocating working principle. Through the reciprocating motion of the piston and the coordination of a one-way valve group, gas pressurization and high-pressure liquid transfer can be completed in the same pump body. It takes into account both high-pressure output and high-flow capacity, and can adapt to pure gas, pure liquid and gas-liquid mixed media. It greatly simplifies the transfer system, improves the compatibility of working conditions, and provides a more efficient solution for high-pressure continuous transfer of complex media.

[0003] In actual working conditions, the gas-liquid mixture to be transported often contains various solid impurities, particles, and dirt. After these foreign objects enter the gas-liquid transfer pump with the medium, they can easily cause damage and failure of key components: small particles can easily get stuck and block the one-way valve, leading to failure of opening and closing and backflow of the medium; hard impurities can directly scratch the cylinder and piston working surface during the reciprocating motion of the piston, destroying the fit accuracy; at the same time, impurities can also aggravate the wear of the seals and cut the sealing surface, causing sealing failure and increased leakage, which seriously affects the stability and service life of the pump, and may even cause the equipment to shut down.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 4As shown in the embodiment of the present invention, a piston-type high-pressure, high-flow gas-liquid transfer pump includes a pump body 1 and a mixing system. The mixing system is used for gas-liquid mixing. One end of the pump body 1 is connected to a filter tank 2. A connecting pipe 3 is provided on the filter pipe, and the connecting pipe 3 is connected to the mixing system. A pair of fixing rings 4 are fixedly connected to the inner wall of the filter tank 2, and a filter screen 5 is fixedly connected to the inner wall of the fixing rings 4. A circular shaft 8 is rotatably connected to the center of the filter screen 5. A first connecting plate 6 is fixedly connected to the outer wall of the circular shaft 8, and a set of brush bristles for cleaning the filter screen 5 is fixedly connected to the inner wall of the first connecting plate 6. A slag discharge assembly is provided inside the filter tank 2, and a drive assembly for driving the circular shaft 8 to rotate is provided inside the filter tank 2. The pump body 1 in this application is a piston-type high-pressure, high-flow gas-liquid transfer pump. After the high-pressure, high-flow gas and liquid are mixed through the mixing system, they are transported to the filter tank 2. At this time, impurities in the mixed gas and liquid are filtered by the double-layer filter screen 5. The impurities are filtered on the filter screen 5 and then enter the pump body 1. By filtering the impurities, unnecessary wear of the components inside the pump body 1 can be avoided. During gas-liquid transfer, the filter screen 5 may become clogged after long-term use, affecting the gas-liquid transfer. At this time, the drive component can be used to control the rotation of the round shaft 8, so that the round shaft 8 drives the first connecting plate 6 to rotate, allowing the bristles to brush off the impurities on the filter screen 5. Then the impurities are discharged from the slag discharge component.

[0022] The drive assembly includes a connecting rod 9, with both ends of the connecting rod 9 fixedly connected to the round shaft 8, and a drive blade 10 fixedly connected to the surface of the connecting rod 9. When the filter screen 5 needs to be cleaned, only gas can be delivered into the filter tank 2. At this time, the gas will drive the drive blade 10 to rotate, thereby causing the drive blade 10 to drive the connecting rod 9 to rotate, so that the round shaft 8 and the first connecting plate 6 can rotate synchronously.

[0023] A second connecting plate 11 is fixedly connected to the outer wall of the circular shaft 8. The second connecting plate 11 has a hollow structure inside. A set of through holes 12 are opened on the side of the second connecting plate 11 near the first connecting plate 6. A water injection component for injecting water into the second connecting plate 11 is provided in the filter tank 2. When cleaning the filter screen 5, the cleaning liquid can be injected into the second connecting plate 11 with the help of the water injection component. When the circular shaft 8 rotates, the first connecting plate 6 and the second connecting plate 11 will rotate synchronously. At this time, the cleaning liquid will be sprayed on the position where the brush bristles clean the filter screen 5, thereby improving the cleaning effect of the filter screen 5. At the same time, the cleaning liquid is in the state of backwashing the filter screen 5, which can wash off the impurities on the filter screen 5 and then flow out with the cleaning liquid.

[0024] The water injection assembly includes a connecting ring 14 that is rotatably and sealingly connected to the outer wall of the connecting rod 9. The connecting ring 14 has a hollow structure inside. A water inlet pipe 15 is fixedly connected to the filter tank 2. The outlet end of the water inlet pipe 15 communicates with the inside of the connecting ring 14. The round shaft 8 and the connecting rod 9 both have hollow structures inside. The round shaft 8 has a first connecting groove 13 that communicates with the inside of the second connecting plate 11. The inner side wall of the connecting ring 14 has a second connecting groove 16. The outer side wall of the connecting rod 9 has a pair of third connecting grooves 17 that correspond to the second connecting grooves 16. When the filter screen 5 needs to be cleaned and unclogged, the cleaning fluid can be injected into the connecting ring 14 from the water inlet pipe 15. Then the cleaning fluid will pass through the connecting rod 9, the round shaft 8 and the second connecting plate 11, and finally be sprayed onto the filter screen 5 from the through hole 12. During the rotation of the connecting rod 9, the second connecting groove 16 will always have a communication part with the third connecting groove 17, so that the cleaning fluid can be continuously sprayed out from the through hole 12.

[0025] The slag discharge assembly includes a pair of slag discharge channels 30 formed on the filter tank 2. The filter tank 2 has a sliding groove 18 that communicates with the slag discharge channels 30. A pair of sealing plates 19 are slidably connected in the sliding groove 18. The sealing plates 19 are used to seal the slag discharge channels 30. In this application, the slag discharge channel 30 is located on one side of the filter surface of the filter screen 5. When cleaning and unblocking the filter screen 5, the sealing plates 19 are moved so that the sealing plates 19 no longer seal the slag discharge channels 30. Subsequently, the impurities that are cleaned off will be discharged from the slag discharge channels 30 along with the cleaning liquid. After cleaning is completed, the sealing plates 19 are moved to seal the slag discharge channels 30.

[0026] An electromagnet 20 is fixedly connected to the inner wall of the chute 18 and magnetically attracted to the sealing plate 19. A spring is fixedly connected between the electromagnet 20 and the sealing plate 19. When it is necessary to control the sealing plate 19 to stop sealing the slag discharge trough 30, the electromagnet 20 can be activated to attract the sealing plate 19, so that the sealing plate 19 stops sealing the slag discharge trough 30. When the electromagnet 20 is closed, the spring will push the plate, so that the sealing plate 19 seals the slag discharge trough 30. The closure of the slag discharge trough 30 can be automatically controlled through the above mechanism.

[0027] A pair of conduits 21 are connected between the slide groove 18 and the connecting ring 14. A control valve is provided on the conduit 21, and a one-way valve is provided in the water inlet pipe 15. After cleaning the filter screen 5, this application can change the magnetic force of the electromagnet 20. When the magnetic force increases, it will attract the sealing plate 19 to move closer to the electromagnet 20. When the magnetic force decreases, the spring will push the sealing plate 19 to move away from the electromagnet 20. When the sealing plate 19 moves closer to the electromagnet 20, the sealing plate 19 will push the gas in the slide groove 18 from the conduit 21 into the connecting ring 14. This gas will finally be blown out from the through hole 12 and then blown onto the bristles to dry the bristles. It can also blow away impurities on the bristles and improve the service life of the bristles.

[0028] Example 2: Figure 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a set of first magnetic sheets 22 are fixedly connected to the side of the second connecting plate 11 near the filter screen 5, and a set of second magnetic sheets 23 corresponding to the first magnetic sheets 22 are fixedly connected to the side of the filter screen 5 near the second connecting plate 11. The second magnetic sheets 23 and the first magnetic sheets 22 are magnetically attracted to each other. In this application, when the second connecting plate 11 rotates, the first magnetic sheets 22 will pass through the second magnetic sheets 23. At this time, the first magnetic sheets 22 will attract the second magnetic sheets 23, thereby causing the second magnetic sheets 23 to attract the filter screen 5 to shake, so as to further assist the impurities on the filter screen 5 to fall off.

[0029] like Figure 6 As shown, a mixing system for a piston-type high-pressure, high-flow gas-liquid transfer pump is described. This system is applicable to the aforementioned piston-type high-pressure, high-flow gas-liquid transfer pump. The mixing system includes a flow-stabilizing buffer tank 24 connected to a connecting pipe 3. One end of the flow-stabilizing buffer tank 24 away from the filter tank 2 is connected to an air inlet pipe 25. An air inlet pipe 26 is connected to the air inlet pipe 25. A round rod 27 is rotatably connected inside the flow-stabilizing buffer tank 24. A mixing blade 28 is fixedly connected to the surface of the round rod 27. In this application, the gas in the gas-liquid mixture can be injected into the flow-stabilizing buffer tank 24 through the air inlet pipe 25, and the liquid can be injected into the flow-stabilizing buffer tank 24 through the liquid inlet pipe 26. The gas and liquid will pass through the flow-stabilizing buffer tank 24. When the gas and liquid pass through the flow-stabilizing buffer tank 24, they will drive the mixing blades 28 to rotate. At this time, the gas and liquid will be stirred and mixed by the mixing blades 28. During the stirring process, large air bubbles can be broken up to prevent large air bubbles from directly rushing into the pump body 1.

[0030] A pair of baffles 29 are fixedly connected to the side of the flow stabilizing buffer tank 24 away from the air inlet pipe 25. Multiple sets of dispersing holes are opened on the baffles 29. In this application, when the gas and liquid pass through the flow stabilizing buffer tank 24, the gas and liquid will pass through the dispersing holes of the baffles 29, so that the air bubbles in the gas and liquid are further dispersed, thereby further improving the stability of the gas and liquid.

[0031] Working principle: The gas and liquid are mixed by a mixing system and then transported to the filter tank 2. Impurities in the mixed gas and liquid are filtered by the double-layer filter screen 5. The impurities are filtered onto the filter screen 5 and then enter the pump body 1. By filtering the impurities, unnecessary wear of the components inside the pump body 1 can be avoided. During gas-liquid transport, the filter screen 5 may become clogged after prolonged use, affecting the transport of gas and liquid. At this time, the drive component can be used to control the rotation of the circular shaft 8, which drives the first connecting plate 6 to rotate, allowing the bristles to brush off the impurities on the filter screen 5. The impurities are then discharged from the slag discharge component. When it is necessary to clean the filter screen 5, only gas can be transported into the filter tank 2. The gas will drive the drive blade 10 to rotate, which in turn drives the connecting rod 9 to rotate, so that the circular shaft 8 and the first connecting plate 6 rotate synchronously. When cleaning the filter screen 5, the cleaning fluid can be injected into the second connecting plate 11 using the water injection component. When the round shaft 8 rotates, the first connecting plate 6 and the second connecting plate 11 will rotate synchronously. At this time, the cleaning fluid will be sprayed onto the position where the brush bristles clean the filter screen 5, thereby improving the cleaning effect of the filter screen 5. At the same time, the cleaning fluid is in a backwashing state for the filter screen 5, which can wash off the impurities on the filter screen 5 and then flow out with the cleaning fluid. When the filter screen 5 needs to be cleaned and unblocked, the cleaning fluid can be injected into the connecting ring 14 from the water inlet pipe 15. Then the cleaning fluid will pass through the connecting rod 9, the round shaft 8 and the second connecting plate 11, and finally spray onto the filter screen 5 from the through hole 12. During the rotation of the connecting rod 9, the second connecting groove 16 will always have a communication part with the third connecting groove 17, so that the cleaning fluid can be continuously sprayed out from the through hole 12. In this application, the slag discharge trough 30 is located on one side of the filter surface of the filter screen 5. When cleaning and unblocking the filter screen 5, the sealing plate 19 is moved so that the sealing plate 19 no longer seals the slag discharge trough 30. Subsequently, the cleaned-off impurities will be discharged from the slag discharge trough 30 along with the cleaning liquid. After cleaning is completed, the sealing plate 19 is moved to seal the slag discharge trough 30. When it is necessary to control the sealing plate 19 to no longer seal the slag discharge trough 30, the electromagnet 20 can be activated to attract the sealing plate 19 so that the sealing plate 19 no longer seals the slag discharge trough 30. When the electromagnet 20 is closed, the spring will push the plate so that the sealing plate 19 seals the slag discharge trough 30. The closure of the slag discharge trough 30 can be automatically controlled through the above mechanism. After cleaning the filter screen 5, this application can change the magnetic force of the electromagnet 20. When the magnetic force increases, it will attract the sealing plate 19 to move closer to the electromagnet 20. When the magnetic force decreases, the spring will push the sealing plate 19 to move away from the electromagnet 20. When the sealing plate 19 moves closer to the electromagnet 20, the sealing plate 19 will push the gas in the slide groove 18 from the conduit 21 into the connecting ring 14. This gas will finally be blown out from the through hole 12 and then blown onto the bristles to dry them. It can also blow away impurities on the bristles and improve the service life of the bristles.
