Description

Technical Field

[0001] This invention relates to the field of rotary jet pump technology, and in particular to a rotary jet pump with a function of rapid air removal from the rotor chamber. Background Technology

[0002] In a rotary jet pump, the rotor is a shell that encloses the water body. The water body rotates together with the rotor, reducing the contact area between the water body and the stationary surface. The working area is only the dynamic and static contact surface between the water body and the collecting pipe. Therefore, the disc friction loss is much smaller than that of a conventional centrifugal pump, and the efficiency is significantly higher than that of a centrifugal pump under the same operating conditions in low specific speed applications.

[0003] Currently, in existing vertical rotary jet pumps, air is often trapped inside the drum before startup, making it difficult to expel quickly. This causes the drum to vibrate frequently during operation due to the presence of this air. Furthermore, when the rotary jet pump needs to be shut down and restarted for a short period, it must be stopped immediately. Frequent starting and stopping of the rotary jet pump causes changes in the internal water and air environment, which can easily damage the pump. In addition, while the rotary jet pump uses filters to reduce the entry of impurities during water intake, these filters are easily clogged after prolonged use, affecting the pump's water intake capacity. Since the filters are generally located inside the equipment, they are not easy to clean quickly.

[0004] To address the aforementioned problems, this invention proposes a rotary jet pump with a function for rapid air removal from the rotor chamber. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of common vertical rotary jet pumps in the prior art, such as difficulty in quickly venting air before starting, the need to shut down the pump directly when it needs to be turned off and restarted for a short time, frequent start-stop of the rotary jet pump causing changes in the internal water and air environment which can easily damage the pump, and difficulty in quickly cleaning the inlet filter.

[0016] Preferably, one end of the rope passes through the fixing block and is fixedly connected to the slide rail. A ball bearing is fixedly connected to one side of the slide rail. The ball bearing slides in a straight groove. The slide rail is slidably connected to the guide rail. The guide rail is fixedly connected to the tank body. The top end of the guide rail is fixedly connected to the fixing block. A first spring is fixedly connected between the fixing block and the slide rail.

[0017] Preferably, the rotary cleaning assembly includes two fixed seats, which are fixedly connected to the bottom wall of the tank. A circular cavity is fixedly connected above the two fixed seats. Two bearing components are fixedly installed inside the circular cavity. A water conveying cavity is rotatably installed on the inner ring of the two bearing components. Multiple water outlets are opened on the water conveying cavity. A cam is fixedly installed on the water conveying cavity.

One end of the torsion spring is fixedly connected to one of the bearing components.

[0022] Compared with the prior art, the present invention provides a rotary jet pump with a rapid air purging function for the rotor cavity, which has the following beneficial effects:

[0023] 1. This rotary spray pump with a rotor chamber air rapid purging function works by reducing the liquid level inside the tank, causing the sealing plug to move downwards under negative pressure. This loosens the rope, and the torque of the torsion spring drives the water delivery chamber to rotate. This, in turn, causes the brush and spray pipe to rotate, increasing the cleaning area of ​​the filter screen. The water delivery chamber also causes the cam to press the roller downwards, causing the connecting rod to deform the second spring via the piston. When the cam's convex surface moves away from the roller, the piston returns to its original position, allowing the cam and second spring to reciprocate the piston's up-and-down movement, guiding the liquid through a double-pass one-way pipe. The liquid is then guided through the water delivery chamber to the spray pipe for further cleaning of the filter screen. Furthermore, the downward movement of the sealing plug via the rope drives the slide rail and ball bearings, causing the ball bearings to rotate through the arc groove, which in turn drives the rotating roller. This, in turn, allows the gear and gear valve to open the water inlet pipe, connecting it to a water source for automatic water supply.

[0024] 2. This rotary jet pump with a rotor chamber air purging function uses the decrease in liquid level in the tank to move the liquid level control component. The liquid level control component also drives the rotary drive component and the gear valve to open the water inlet pipe. After the water inlet pipe is opened, the upper interface is closed through the three-way valve. At this time, the pump body can deliver the liquid back to the tank through the water delivery pipe and the three-way valve. Water is added through the water inlet pipe, so that the pump body achieves the purpose of water circulation. This avoids the need to stop the operation during the water filling process and prevents the pump body from being easily damaged by frequent start and stop.

[0025] 3. This rotary jet pump with a rotor chamber air rapid purging function allows water to be supplied through the inlet pipe. At this time, the three-way valve remains connected to the water delivery chamber, and the water delivery assembly can deliver water into the tank and then extract it through the tank, thus achieving water circulation. During the water circulation process, the water is discharged through the water delivery chamber, allowing the liquid to pass through the spiral blades. The liquid is injected under high pressure, causing the water pressure to control the rotation of the spiral blades. The spiral blades drive the rotation of the water delivery chamber, which in turn drives the torsion spring to twist. The water delivery chamber also drives the brush and spray pipe to rotate, and the liquid is sprayed out under high pressure through the nozzles of the spray pipe. Thus, the high-pressure spray force of the water circulation can improve the cleaning effect of the filter screen and increase the water intake capacity of the outlet chamber.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Example 1: Refer to Figure 1-12 A rotary jet pump with a rotor cavity air rapid exhaust function includes a water delivery mechanism 100, in which a drainage and cleaning mechanism 200 is installed.

[0042] The water conveying mechanism 100 includes a base plate 102. A water storage component 104 and a water conveying component 101 are disposed above the base plate 102. The water conveying component 101 is connected to the water storage component 104. The water storage component 104 includes a tank 1041, which is fixedly mounted on the base plate 102. One end of a three-way valve 1013 passes through the tank 1041. The tank 1041 serves to store water for easy water supply. A water outlet chamber 1042 is installed through the upper part of the tank 1041. A filter screen 1043 is installed inside the water outlet chamber 1042. The water outlet chamber 1042 can connect the pump body 1011 and the tank 1041, allowing the pump body 1011 to smoothly convey water through the water outlet chamber 1042. Furthermore, the filter screen 1043 on the water outlet chamber 1042 can perform filtration. The function of the water outlet chamber 1042 is as follows: one end of the water outlet chamber 1042 is connected to the pump body 1011. A liquid level control component 106 is installed in the water storage assembly 104. The liquid level control component 106 includes a sealing plug 1061, which is located in the tank body 1041 and maintains a seal with the inner wall of the tank body 1041. When the liquid level drops, negative pressure can pull the sealing plug 1061 downwards, thereby enabling the sealing plug 1061 to pull the rope 1062. A rope 1062 is fixedly connected above the sealing plug 1061. The rope 1062 passes through two pulleys 1064, which are rotatably mounted on a support frame 1063. The support frame 1063 supports and fixes the pulleys 1064, allowing the pulleys 1064 to move the rope. The cable 1062 guides the pulley 1064, allowing it to rotate. The pulley 1064 is also rotatable, reducing frictional resistance during the cable's movement and ensuring smooth sliding. The support frame 1063 is fixedly connected to the tank 1041. One end of the cable 1062 passes through the fixing block 1035 and is fixedly connected to the slide rail 1067. A ball bearing 1068 is fixedly connected to one side of the slide rail 1067. The ball bearing 1068 slides in the linear groove 1034, which maintains its vertical movement and reduces friction, improving smooth movement. The slide rail 1067 is slidably connected to the guide rail 1065. The guide rail 1065 guides the slide rail 1067, allowing the slide rail 1067 to move smoothly up and down along the guide rail 1065. Both the guide rail 1065 and the slide rail 1067 are dovetail-shaped to prevent the slide rail 1067 from disengaging from the guide rail 1065, thus allowing the ball bearing 1068 to move smoothly up and down. The guide rail 1065 is fixedly connected to the tank body 1041, and its top end is fixedly connected to the fixing block 1035. A first spring 1066 is fixedly connected between the fixing block 1035 and the slide rail 1067. The first spring 1066 drives the slide rail 1067 to smoothly complete its downward reset action. The liquid level control component 106 also extends into a water storage component 104 located on one side. A rotary drive component 103 is connected to one side of the liquid level control component 106.The rotary drive assembly 103 includes a fixed block 1035 and a rotating roller 1031. The fixed block 1035 is fixedly connected to the tank body 1041. The rotating roller 1031 is rotatably mounted on the fixed block 1035 via bearings. The rotating roller 1031 can maintain stable rotation through the bearings, allowing the gear 1032 to stably transmit power with the gear valve 1052. The bottom end of the rotating roller 1031 is fixedly connected to the gear 1032, which meshes with the gear valve 1052. Through the meshing transmission between the gear 1032 and the gear valve 1052, the gear valve 1052 can control the opening and closing of the water inlet pipe 1051, thereby facilitating automatic water filling through the water inlet pipe 1051. The rotating roller 1031 has two arc-shaped grooves 1033 and two straight grooves 1034. 34. The upper and lower ends of the two straight grooves 1034 are respectively connected to the two arc-shaped grooves 1033. When the ball bearing 1068 enters the arc-shaped groove 1033, the ball bearing 1068 can control the rotation of the roller 1031 through the arc surface of the arc-shaped groove 1033, so that the roller 1031 can drive the gear 1032 to rotate. The bottom of the rotation drive assembly 103 is equipped with a water inlet assembly 105. The water inlet assembly 105 includes a water inlet pipe 1051, which can be connected to a water source. Water can then be injected into the tank 1041 through the water inlet pipe 1051. The water inlet pipe 1051 is connected to the bottom of the tank 1041, and a toothed valve 1052 is fixedly installed on the water inlet pipe 1051. The water inlet assembly 105 is connected to the water storage assembly 104.

[0043] The drainage cleaning mechanism 200 includes a water pressure assembly 201, which includes a sealing shell 2016. The sealing shell 2016 is fixedly installed on the bottom wall of the tank 1041. One-way valves 2014 are fixedly installed on both the upper and lower sides of one side of the sealing shell 2016. The one-way valves 2014 maintain unidirectional liquid inflow. When the piston 2011 moves downward, the upper one-way valve 2014 allows unidirectional liquid inflow, while the lower one-way valve 2014 opens, thus enabling the switching of water intake. The other side of the sealing shell 2016 is connected to a double-pass one-way pipe 2017. The two ends of the double-pass one-way pipe 2017 are respectively connected to the upper and lower sides of the other side of the sealing shell 2016, thereby allowing the piston 2011 to move up and down... The movement can be switched between the two ends of the double-pass one-way pipe 2017, which is connected to the water inlet pipe 2018. The water inlet pipe 2018 can be connected to the circular cavity 2024, thus facilitating water conveyance. The water inlet pipe 2018 is connected to the circular cavity 2024. A piston 2011 is installed inside the sealing shell 2016. A second spring 2013 is fixedly connected between the top of the piston 2011 and the top wall of the sealing shell 2016. The restoring force of the second spring 2013 can drive the piston 2011 to return to its original position. Meanwhile, the cam 2021, through the roller 2015 and the connecting rod 2012, squeezes the piston 2011 downward, so that the cam 2021 can cooperate with the second spring 2013 to realize the reciprocating motion of the piston 2011, thereby achieving... To achieve reciprocating drainage, a connecting rod 2012 is fixedly connected above the piston 2011. The connecting rod 2012 passes through the sealing shell 2016 and is fixedly connected to the roller 2015. The roller 2015 reduces the resistance between itself and the cam 2021, thus maintaining smooth operation. The roller 2015 is positioned below the cam 2021. A rotary cleaning assembly 202 is connected above the water pressure assembly 201. The rotary cleaning assembly 202 includes two fixed seats 2023, which are fixedly connected to the bottom wall of the tank 1041. A circular cavity 2024 is fixedly connected above the two fixed seats 2023. Two bearing components 2027 are fixedly installed inside the circular cavity 2024. The inner rings of the two bearing components 2027 are rotatably mounted with conveying devices. The water chamber 2025, assisted by bearing 2027, allows for smooth rotation. Multiple outlets 2026 are provided on the water chamber 2025 to guide liquid smoothly into it. A cam 2021 is fixedly installed on the water chamber 2025. Multiple spiral blades 2022 are fixedly connected inside the water chamber 2025. After high-pressure water is input into the water chamber 2025 by the three-way valve 1013, the high-pressure water impacts the spiral blades 2022, thereby driving the water chamber 2025 to rotate. A spray pipe 2028 is connected to one side of the water chamber 2025, and a nozzle is provided on the spray pipe 2028 to spray liquid, thereby cleaning the filter screen 1043.The spray pipe 2028 corresponds to the filter screen 1043. A brush 2029 is fixedly connected to the lower part of the spray pipe 2028. The brush 2029 rests on the filter screen 1043 and can clean the filter screen 1043. The other side of the water supply chamber 2025 is rotatably mounted on one end of the three-way valve 1013 via a bearing, and the water supply chamber 2025 is connected to one end of the three-way valve 1013. One end of the rotating cleaning component 202 is connected to the end of the water supply component 101 that extends to the water storage component 104. A rotating control component 203 is provided on the rotating cleaning component 202. The rotating control component 203 includes a rope disc 2031, which is fixedly connected to the water supply chamber 2025. A rope belt 20 is wound around the rope disc 2031. 33. The rope 2033 can move upwards with the sealing plug 1061 and is stretchable, allowing the rope reel 2031 to rotate and release the rope 2033. The rotation of the rope reel 2031 also drives the torsion spring 2032 to store elastic potential energy. The upper end of the rope 2033 is fixedly connected to the sealing plug 1061, and the torsion spring 2032 is fixedly connected to one side of the rope reel 2031. When the sealing plug 1061 moves downwards, the torque of the torsion spring 2032 is released, causing the rope reel 2031 to rotate and rewind the rope 2033. Simultaneously, it drives the water delivery chamber 2025 to rotate. The torsion spring 2032 is sleeved on the water delivery chamber 2025, and one end of the torsion spring 2032 is fixedly connected to one of the bearing components 2027. The top of the rotation control component 203 is connected to the liquid level control component 106.

[0044] In this embodiment: as the liquid inside the tank 1041 decreases, the sealing plug 1061 moves downward with the liquid level due to negative pressure. This loosens the rope 2033, allowing the torsion spring 2032 to rotate the water delivery chamber 2025. The water delivery chamber 2025 then rotates the brush 2029 and the spray pipe 2028, increasing the cleaning area of ​​the brush 2029 on the filter screen 1043. Furthermore, the water delivery chamber 2025 causes the cam 2021 to press the roller 2015 downwards, causing the connecting rod 2012 to deform via the piston 2011, which in turn deforms the second spring 2013. When the convex surface of the cam 2021 moves away from the roller 2015, the piston 2011 returns to its original position, causing the convex surface to... Wheel 2021, in conjunction with second spring 2013, enables piston 2011 to move up and down for reciprocating flow, and discharges liquid through double-pass one-way pipe 2017. The liquid is then guided through water delivery chamber 2025 to spray out through spray pipe 2028, thereby further cleaning filter screen 1043. Next, sealing plug 1061 moves downward through rope 1062 to drive slide rail 1067 and ball bearing 1068 to move. Ball bearing 1068 drives roller 1031 to rotate through arc groove 1033. This allows gear 1032 to drive gear valve 1052 to open water inlet pipe 1051, thus connecting water inlet pipe 1051 to water source for automatic water supply.

[0045] Example 2: Refer to Figure 2-6A rotary jet pump with a rotor chamber air rapid purging function includes a water delivery assembly 101, which includes a pump body 1011. The pump body 1011 is fixedly installed on a base plate 102. One end of the pump body 1011 is connected to a water delivery pipe 1012. The pump body 1011 can deliver water through the water delivery pipe 1012 and can smoothly achieve water supply through the upper interface of a three-way valve 1013. When the other end of the three-way valve 1013 is opened to connect with the water delivery chamber 2025, water can be delivered to the tank 1041 to achieve water circulation. The end of the water delivery pipe 1012 away from the pump body 1011 is connected to the three-way valve 1013. The pump body 1011 is provided with a rotor chamber 1015 and a guide pipe 1014. When the pump body 1011 is running, the rotor chamber 1015 rotates, which can quickly discharge air from the guide pipe 1014, and at the same time facilitate the rapid purging of air. The guide pipe extends out from the rotor chamber 1015.

[0046] The water intake assembly 105 includes an inlet pipe 1051, which is connected to the bottom of the tank 1041, and a toothed valve 1052 is fixedly installed on the inlet pipe 1051.

[0047] The water storage assembly 104 includes a tank 1041, which is fixedly installed on the base plate 102. One end of the three-way valve 1013 passes through the tank 1041. A water outlet chamber 1042 is installed through the upper part of the tank 1041. A filter screen 1043 is installed in the inner cavity of the water outlet chamber 1042. One end of the water outlet chamber 1042 is connected to the pump body 1011.

[0048] In this embodiment: as the liquid level in tank 1041 decreases, the liquid level control component 106 moves with the liquid level. The liquid level control component 106 also drives the rotary drive component 103 to drive the gear valve 1052, thereby opening the water inlet pipe 1051. After the water inlet pipe 1051 is opened, the upper interface is closed by the three-way valve 1013. At this time, the pump body 1011 can transport the liquid back into tank 1041 through the water delivery pipe 1012 and the three-way valve 1013. As water is added through the water inlet pipe 1051, the pump body 1011 achieves the purpose of water circulation, avoiding the need to stop the machine during the water filling process and preventing the pump body 1011 from being easily damaged by frequent start-stop.

[0049] Example 3: Reference Figure 2 , Figure 4 and Figure 12A rotary jet pump with a rotor chamber air rapid purging function includes a water intake assembly 105, which includes an inlet pipe 1051 connected to the lower part of a tank 1041. A toothed valve 1052 is fixedly installed on the inlet pipe 1051. The water delivery assembly 101 includes a pump body 1011 fixedly installed on a base plate 102. One end of the pump body 1011 is connected to a water delivery pipe 1012, and the end of the water delivery pipe 1012 away from the pump body 1011 is connected to a three-way valve 1013.

[0050] The rotary cleaning assembly 202 includes two fixed seats 2023, which are fixedly connected to the bottom wall of the tank 1041. A circular cavity 2024 is fixedly connected above the two fixed seats 2023. Two bearing components 2027 are fixedly installed inside the circular cavity 2024. A water delivery chamber 2025 is rotatably mounted on the inner ring of the two bearing components 2027. Multiple water outlets 2026 are provided on the water delivery chamber 2025. A cam 2021 is fixedly installed on the water delivery chamber 2025. Multiple spiral blades 2022 are fixedly connected inside the water supply chamber 2025. A spray pipe 2028 is connected to one side of the water supply chamber 2025. A nozzle is provided on the spray pipe 2028, and the spray pipe 2028 corresponds to the filter screen 1043. A brush 2029 is fixedly connected to the bottom of the spray pipe 2028. The brush 2029 is placed on the filter screen 1043. The other side of the water supply chamber 2025 is rotatably mounted on one end of the three-way valve 1013 through a bearing, and the water supply chamber 2025 is connected to one end of the three-way valve 1013.

[0051] In this embodiment: water supply is initiated by opening the inlet pipe 1051. At this time, the three-way valve 1013 remains connected to the water delivery chamber 2025, and the water delivery assembly 101 can deliver water into the tank 1041 and extract it through the tank 1041, thereby realizing water circulation. During the water circulation process, the water is discharged through the water delivery chamber 2025, allowing the liquid to pass through the spiral blade 2022. The liquid is injected under high pressure, causing the water pressure to control the rotation of the spiral blade 2022. The spiral blade 2022 drives the water delivery chamber 2025 to rotate, which in turn drives the torsion spring 2032 to twist. The water delivery chamber 2025 also drives the brush 2029 and the spray pipe 2028 to rotate, and the liquid is sprayed out under high pressure through the nozzle of the spray pipe 2028. Thus, the high-pressure spray force of the water circulation can improve the cleaning effect of the filter screen 1043 and improve the water intake capacity of the outlet chamber 1042.

[0052] Working principle: During water transfer, the pump body 1011 is operated, and the pump body 1011 pumps water through the outlet chamber 1042, allowing the liquid to be transported through the water pipe 1012 and outward through the upper interface of the three-way valve 1013. As the water level inside the tank 1041 decreases, the sealing plug 1061 moves downward with the liquid level. The sealing plug 1061 also pulls the rope 1062 to move, and the rope 1062 pulls the slide rail 1067 upward. The slide rail 1067 causes the first spring 1066 to deform, causing the slide rail 1067 to drive the ball bearing 10... 68 slides upward in the straight groove 1034. When the ball 1068 slides to the top of the straight groove 1034 and enters the arc groove 1033, the ball 1068 controls the rotation of the roller 1031 through the arc surface of the arc groove 1033, so that the ball 1068 enters another straight groove 1034. During the rotation of the roller 1031, the roller 1031 drives the gear 1032 to rotate. The gear 1032 drives the gear valve 1052. The gear valve 1052 opens the water inlet pipe 1051. At this time, water can be injected through the water source through the water inlet pipe 1051.

[0053] During the downward movement of piston 2011, the rope 2033 loosens. At this time, torsion spring 2032 releases torque, driving water delivery chamber 2025 to rotate. Water delivery chamber 2025 drives spray pipe 2028 and brush 2029 to rotate. Brush 2029 rotates to clean filter screen 1043. The rotation of water delivery chamber 2025 also drives cam 2021 to rotate. The convex surface of cam 2021 presses roller 2015 to move. Roller 2015 drives connecting rod 2012 and piston 2011 to move downward, causing piston 2011 to deform second spring 2013. When cam 2021... The convex surface moves away from the roller 2015, causing the second spring 2013 to drive the piston 2011 to return upward until the cam 2021 presses the roller 2015 again, so that the second spring 2013 can cooperate with the cam 2021 to realize the up and down movement of the piston 2011. The up and down movement of the piston 2011 can be used to draw water through the one-way valve 2014, and the piston 2011 can also be discharged through the double-pass one-way pipe 2017, and discharged into the water supply chamber 2025 through the water inlet pipe 2018 and the water outlet 2026, and sprayed out through the nozzle of the spray pipe 2028 to clean the filter screen 1043.

[0054] After the inlet pipe 1051 is opened, the upper interface is closed by the three-way valve 1013. At this time, the pump body 1011 continues to draw liquid from the tank 1041 and inputs it into the water delivery chamber 2025 through the three-way valve 1013. The liquid is sprayed out through the nozzle of the spray pipe 2028 to clean the filter screen 1043. Moreover, the high-pressure water flushing pressure can drive the spiral blade 2022 to rotate. The spiral blade 2022 drives the water delivery chamber 2025 to rotate. The water delivery chamber 2025 drives the spray pipe 2028 and the brush 2029 to rotate to further clean the filter screen 1043.

[0055] When the liquid level inside the tank 1041 rises, the sealing plug 1061 moves upward, pulling the rope 2033. The rope 2033, through the rope disc 2031, drives the torsion spring 2032 to store elastic potential energy. At this time, the rope 1062 loosens, and the first spring 1066 drives the slide rail 1067 to return to its original position. The slide rail 1067 drives the ball bearing 1068 to move downward along the straight groove 1034. When the ball bearing 1068 enters the lower arc groove 1033, the roller 1031 rotates and drives the gear 1032 to drive the gear valve 1052, closing the water inlet pipe 1051. At the same time, the three-way valve 1013 closes its connection with the water delivery chamber 2025, opening the upper interface of the three-way valve 1013, thus restarting the water delivery operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
