Description

Technical Field

[0001] This invention relates to the field of cyclone pump technology, and more specifically, to a washing cyclone pump with a material size selection structure. Background Technology

[0002] A cyclone pump is a device named for the rotating vortex motion of the fluid inside it. The structural features of a cyclone pump are that the impeller is open or semi-open, the blades are straight and arranged radially, and there is a relatively wide axial space between the impeller and the front pump casing. This provides good conditions for solid media to pass through the pump body. Cyclone pumps are mostly used to pump complex media or fluids containing impurities, such as two-phase fluids containing garbage, short fiber materials or feces.

[0003] To clean solid particles from impurity fluids and achieve fluid washing, a cyclone pump can extract these solid particles. However, existing cyclone pumps use centrifugation to allow solid particles in the impurity fluid to gain energy under the action of axial vortex, resulting in solid particles with a diameter approximately equal to the pump outlet being discharged. The flow area at the pump outlet cannot be adjusted, making it impossible to specifically extract solid particles of different sizes from the impurity fluid. Furthermore, the circulating flow in the cyclone pump also affects its efficiency. Therefore, a washing cyclone pump with a material size selection structure is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a washing cyclone pump with a material size selection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a washing vortex pump with a material size selection structure, comprising an integrated plate and a motor, a connector, and a vortex pump disposed on the top of the integrated plate. The connector is connected to the vortex pump. The vortex pump includes a pump casing fixed to one end of the top of the integrated plate and an impeller disposed within the pump casing. The top of the pump casing is connected to an inlet pipe and an outlet pipe. The inlet pipe contains an anti-backflow fluid, and the outlet pipe contains a selector. The selector includes an adjustment structure and an adjustment plate connected to the bottom of the adjustment structure. The adjustment structure is used to adjust the deflection angle of the adjustment plate. Straight blades are radially arranged on the surface of the impeller. A transmission port is opened on the side of the pump casing near the motor. A transmission shaft is coaxially connected to the surface of the impeller near the motor. The motor passes through the transmission port and is connected to the transmission shaft. A fluid-breaking fluid is connected to the side of the impeller away from the transmission shaft.

[0006] As a further improvement to this technical solution, the adjustment structure includes a top ring that is clamped to the inner wall of the outlet pipe. A groove is formed inside the top ring, and a gear ring is rotatably connected within the groove. A lever is provided on the outer surface of the gear ring, passing through the outer surface of the top ring. Vertical grooves are symmetrically formed on the inner wall of the top ring, and a gear rod is rotatably connected within each groove. The gear rod includes a vertical rod located within the groove and a gear positioned at the top of the vertical rod. The top of the gear rod meshes with the gear inside the gear ring. A connecting plate is provided on the side of the adjustment plate near the inner wall of the top ring. Multiple side openings are symmetrically formed at the bottom of the top ring, and these side openings are rotatably connected to the connecting plate. A connecting groove is formed in the middle of the side of the connecting plate away from the adjustment plate. A screw sleeve is threaded onto the surface of the gear rod, and the screw sleeve is rotatably connected to the connecting groove.

[0007] As a further improvement to this technical solution, the adjustment plate is a quarter-sector ring structure.

[0008] As a further improvement to this technical solution, the fluid breaking includes a blade and an outer cap rotatably connected to the blade. A slot is provided on the surface of the pump casing away from the transmission port. The outer cap engages with the slot. One end of the blade is connected to the middle of the impeller surface, and the other end of the blade is located inside the outer cap.

[0009] As a further improvement to this technical solution, a movable groove is provided in the middle of the surface of the impeller away from the drive shaft, and a cross plate is provided at one end of the blade near the impeller. The cross plate is located in the movable groove and is engaged with the movable groove. A reciprocating thread is provided on the surface of the other end of the blade, and the other end of the blade is connected to the inner thread of the outer cap.

[0010] As a further improvement to this technical solution, the impeller surface away from the drive shaft is symmetrically provided with multiple arc-shaped blocks.

[0011] As a further improvement to this technical solution, the anti-reverse fluid includes an inlet cylinder that is stuck in the inner wall of the inlet pipe and a blockage located in the inlet cylinder. The blockage surface is provided with sliders symmetrically at the four corners, and the inner wall of the inlet cylinder is provided with corresponding grooves. The sliders are slidably connected to the grooves.

[0012] As a further improvement to this technical solution, the blockage is a hollow cone structure.

[0013] As a further improvement to this technical solution, a fixing body is sleeved on the surface of the transmission shaft. The fixing body is located inside the transmission port. The fixing body is a "medium" shaped cylinder, and both ends of the fixing body are engaged with the inside of the transmission port.

[0014] As a further improvement to this technical solution, the inner wall of the fixed body is provided with a liquid groove with an annular cross-section. The liquid groove is connected to an inlet pipe and an outlet pipe, which pass through the surface of the pump casing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this washing cyclone pump with a material size selection structure, an adjustment structure is provided. By moving the lever, the gear ring rotates in the ring groove, causing the gear ring to drive the gear rod meshing with the gear ring to rotate in the vertical groove. Then, through the screw sleeve threaded to the gear rod, the adjustment plate rotates in the side opening, thereby adjusting the deflection angle of the adjustment plate and adjusting the flow area in the water outlet pipe, which can selectively extract solid particles of different sizes from the impurity fluid.

[0017] 2. In this washing cyclone pump with material size selection structure, a fluid breaker is provided. When the impeller rotates, the impeller drives the blades to rotate synchronously. When the blades rotate, they drive the liquid in the pump casing to move towards the impeller surface, disturbing and destroying the circulating flow in the middle of the impeller surface, and driving the liquid to flow towards the straight blades of the impeller, thereby improving the efficiency of the cyclone pump.

[0018] 3. In this washing cyclone pump with material size selection structure, the other end of the blade moves axially when it rotates inside the outer cap through snap-fit ​​and threaded connection. That is, when the blade rotates to drive the liquid to flow to the impeller surface, the blade itself will reciprocate along the impeller axis, thereby further promoting the flow of liquid. In addition, by providing an arc-shaped block, the liquid can flow outward along the arc surface of the arc-shaped block to the straight blades of the impeller, further reducing the circulating flow in the middle of the impeller.

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.

[0039] Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Example 1

[0040] Please see Figures 1-10 As shown, the purpose of this embodiment is to provide a washing vortex pump with a material size selection structure, including an integrated plate 11 and a motor 12, a connector 13, and a vortex pump 2 disposed on the top of the integrated plate 11. The connector 13 is connected to the vortex pump 2. The vortex pump 2 includes a pump housing 21 fixed to one end of the top of the integrated plate 11 and an impeller 24 disposed inside the pump housing 21. The top of the pump housing 21 is connected to an inlet pipe and an outlet pipe. The inlet pipe is provided with an anti-backflow fluid 22 to prevent liquid in the pump housing 21 from flowing backward out of the inlet. The outlet pipe is provided with a selector 23. The selector 23 contains... The pump includes an adjustment structure and an adjustment plate 232 connected to the bottom of the adjustment structure. The adjustment structure is used to adjust the deflection angle of the adjustment plate 232. The adjustment plate 232 is used to reduce the flow area in the outlet pipe. Straight blades are arranged radially on the surface of the impeller 24. A transmission port 211 is opened on the side of the pump casing 21 near the motor 12. A transmission shaft 241 is coaxially connected to the surface of the impeller 24 near the motor 12. The motor 12 passes through the transmission port 211 and is connected to the transmission shaft 241. A fluid breaker 25 is connected to the side of the impeller 24 away from the transmission shaft 241. The fluid breaker 25 is used to break the circulating flow generated during the operation of the cyclone pump.

[0041] In this embodiment, during actual use, liquid enters the pump casing 21 through the inlet pipe. The motor 12 drives the impeller 24 to rotate within the pump casing 21 via the transmission shaft 241. When the impeller 24 rotates, the medium's energy increases due to centrifugal force. The medium entering between the blades is pushed by the blades and moves together with the impeller 24. When the impeller 24 rotates within the pump, it generates two forces on the liquid: a force that causes the liquid to move in a circular motion along the direction of rotation and a force that throws the liquid radially. As a result, the liquid at the straight blades of the impeller 24 forms an axial vortex, and the medium near the top of the impeller 24 outlet forms a through flow due to the greater centrifugal force. The medium in the middle of the impeller 24 forms a circulating flow. Solid particles in the through flow move within the cavity and are discharged through the outlet pipe. Solid particles approximately the same diameter as the outlet pipe can pass through. A lever is moved to rotate the gear ring 234 within the annular groove 233, causing the gear ring 234 to drive the gear rod 235 meshing with it. Rotating within the vertical groove reduces the flow area within the outlet pipe, thereby allowing for the selection of solid particle sizes discharged from the cyclone pump. Furthermore, when the impeller 24 rotates, it drives the blades 251 to rotate synchronously. The rotation of the blades 251 drives the liquid within the pump casing 21 towards the surface of the impeller 24, disrupting and breaking the circulating flow in the center of the impeller 24 surface, and driving the liquid towards the straight blades of the impeller 24. Since the other end of the blade 251 is connected to the outer cap 252 via a reciprocating thread, the other end of the blade 251 will move axially when rotating within the outer cap 252. That is, when the blade 251 rotates to drive the liquid towards the surface of the impeller 24, the blade 251 itself will reciprocate along the axial direction of the impeller 24, further promoting the flow of the liquid. This allows the liquid to flow outwards along the arc-shaped surface of the arc block 243 to the straight blades of the impeller 24, further reducing the circulating flow in the center of the impeller 24 and improving the efficiency of the cyclone pump.

[0042] In this embodiment, to facilitate adjustment of the deflection angle of the adjusting plate 232, the adjusting structure includes a top ring 231 that is clamped to the inner wall of the water outlet pipe. A groove 233 is formed inside the top ring 231, and a gear ring 234 is rotatably connected within the groove 233. A lever is provided on the outer surface of the gear ring 234, passing through the outer surface of the top ring 231. Vertical grooves are symmetrically formed on the inner wall of the top ring 231, and a gear rod 235 is rotatably connected within each groove. The gear rod 235 includes a vertical rod located within the groove and a gear located at the top of the vertical rod. The top of the gear rod 235 meshes with the gear inside the gear ring 234. A connecting plate is provided on the side of the adjusting plate 232 near the inner wall of the top ring 231. Multiple side openings 237 are symmetrically opened at the bottom of 231. The side openings 237 are rotatably connected to the connecting plate. A connecting groove is opened in the middle of the side of the connecting plate away from the adjusting plate 232. A screw sleeve 236 is threadedly connected to the surface of the gear rod 235. The screw sleeve 236 is rotatably connected to the connecting groove. By providing an adjustment structure, the lever is moved to drive the gear ring 234 to rotate in the ring groove 233. This causes the gear ring 234 to drive the gear rod 235, which meshes with the gear ring 234, to rotate in the vertical groove. Then, through the screw sleeve 236 threadedly connected to the gear rod 235, the adjusting plate 232 is driven to rotate in the side openings 237, thereby adjusting the deflection angle of the adjusting plate 232.

[0043] To facilitate the deflection and closure of the regulating plate 232, the regulating plate 232 is a quarter-sector ring structure. By setting the regulating plate 232 as a quarter-sector ring structure, the rotation of the regulating plate 232 will not affect the rotation of the adjacent regulating plate 232. Furthermore, when the regulating plate 232 deflects and closes, it can combine with the adjacent regulating plate 232 to form a complete ring structure, which facilitates the outflow of liquid in the pump casing 21 and is beneficial to the deflection and closure of the regulating plate 232.

[0044] Considering that the circulating flow of the cyclone pump must be reduced in order to improve the efficiency of the cyclone pump, the breaker 25 includes a blade 251 and an outer cap 252 rotatably connected to the blade 251. A slot 212 is provided on the surface of the pump casing 21 away from the drive port 211. The outer cap 252 is engaged with the slot 212. One end of the blade 251 is connected to the middle of the surface of the impeller 24, and the other end of the blade 251 is located inside the outer cap 252. By providing the breaker 25, when the impeller 24 rotates, the impeller 24 drives the blade 251 to rotate synchronously. When the blade 251 rotates, it drives the liquid in the pump casing 21 to move towards the surface of the impeller 24, disturbing and destroying the circulating flow in the middle of the surface of the impeller 24, and driving the liquid to flow towards the straight blades of the impeller 24, thereby improving the efficiency of the cyclone pump.

[0045] To enhance the effect of disrupting the circulating flow, a movable groove 242 is provided in the middle of the surface of the impeller 24 away from the drive shaft 241. The movable groove 242 is a cross groove. A cross plate 253 is provided at one end of the blade 251 near the impeller 24. The cross plate 253 is located in the movable groove 242 and is engaged with the movable groove 242. A reciprocating thread is provided on the surface of the other end of the blade 251. The other end of the blade 251 is internally threaded to the outer cap 252. When the impeller 24 drives the blade 251 to rotate through the engaged cross plate 253, the other end of the blade 251 is connected to the outer cap 252 through the reciprocating thread. This causes the other end of the blade 251 to move axially when rotating inside the outer cap 252. That is, when the blade 251 rotates to drive the liquid to flow to the surface of the impeller 24, the blade 251 itself will reciprocate along the axial direction of the impeller 24, thereby further promoting the flow of the liquid and enhancing the effect of disrupting the circulating flow.

[0046] To facilitate the flow of liquid to the straight blades of the impeller 24, a plurality of arc-shaped blocks 243 are symmetrically arranged on the surface of the impeller 24 away from the drive shaft 241. By providing the arc-shaped blocks 243, the liquid can flow outward along the arc surface of the arc-shaped blocks 243 to the straight blades of the impeller 24, further reducing the circulating flow in the middle of the impeller 24.

[0047] To prevent the backflow of liquid inside the pump casing 21, the anti-backflow fluid 22 includes an inlet cylinder 221 that is stuck in the inner wall of the inlet pipe and a plug 222 located inside the inlet cylinder 221. The plug 222 has symmetrical sliders 223 on its four corners. The inner wall of the inlet cylinder 221 has corresponding grooves. The sliders 223 are slidably connected to the grooves. With the anti-backflow fluid 22, when the liquid inside the pump casing 21 flows back, it will push the plug 222 to make the sliders 223 move along the grooves until the plug 222 blocks the inlet cylinder 221. At this time, the liquid inside the pump casing 21 cannot flow out of the inlet pipe. When the liquid inside the pump casing 21 is discharged from the outlet pipe, due to the negative pressure inside, the liquid in the inlet pipe pushes the plug 222 to move in the opposite direction and enter the pump casing 21.

[0048] To prevent the medium in the liquid from entering the inlet pipe and causing blockage when the liquid in the pump casing 21 flows back, the plug 222 is a hollow cone structure. By setting the plug 222 as a hollow cone structure, when the liquid flows back, it enters the hollow cavity of the plug 222 and pushes the plug 222 to move. That is, the medium in the liquid is trapped in the hollow cavity, thereby preventing the medium from flowing back into the inlet pipe and causing blockage.

[0049] To ensure the stability of the impeller 24 during rotation, a fixed body 244 is sleeved on the surface of the drive shaft 241. The fixed body 244 is located inside the drive port 211 and is a "medium" shaped cylinder. Both ends of the fixed body 244 are engaged with the drive port 211. By providing the fixed body 244, the drive shaft 241 is confined within the fixed body 244 when the impeller 24 rotates to avoid centrifugal rotation of the drive shaft 241, thereby ensuring the stability of the impeller 24 during rotation.

[0050] Considering that the drive shaft 241 will heat up due to friction when rotating inside the fixed body 244, the inner wall of the fixed body 244 is provided with a liquid groove 245 with an annular cross section. The liquid groove 245 is connected to the liquid inlet pipe 246 and the liquid outlet pipe 247. The liquid inlet pipe 246 and the liquid outlet pipe 247 pass through the surface of the pump housing 21. By filling the liquid groove 245 with water and performing water cooling, the heat of friction can be removed, thereby preventing the temperature from rising.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
