Description

Technical Field

[0001] This utility model relates to the field of mixed flow pump technology, specifically a mixed flow pump with a multi-stage filtration structure. Background Technology

[0002] A mixed-flow pump is a type of pump that falls between a centrifugal pump and an axial-flow pump. The specific speed of a mixed-flow pump is higher than that of a centrifugal pump but lower than that of an axial-flow pump. Its head is higher than that of an axial-flow pump, but its flow rate is lower than that of an axial-flow pump but higher than that of a centrifugal pump. When the prime mover drives the impeller to rotate, the liquid is subjected to both centrifugal force and axial thrust. It is a combination of centrifugal pump and axial-flow pump. The liquid flows out of the impeller at an angle.

[0003] Existing mixed-flow pumps typically use filter screens for filtration. However, after a period of use, the filter screens need to be cleaned, which requires disassembly and cleaning. This is time-consuming, labor-intensive, and reduces cleaning efficiency. To address this, we propose a mixed-flow pump with a multi-stage filtration structure. Utility Model Content

[0004] The purpose of this invention is to provide a mixed-flow pump with a multi-stage filtration structure to solve the problem mentioned in the background art that the filter screen needs to be cleaned after the mixed-flow pump has been used for a period of time, which requires disassembling and cleaning the filter screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixed-flow pump with a multi-stage filtration structure, comprising a base and a connecting pipe, wherein the connecting pipe is located on the right side of the base, a rotating ring is rotatably connected to the left and right sides of the outer sidewall of the connecting pipe, a sealing pipe is fixedly connected between the inner sidewalls of the rotating ring, and the sealing pipe is sleeved on the outside of the connecting pipe, a sealing ring is embedded in the left and right sides of the inner cavity wall of the sealing pipe, through holes are evenly distributed around the left and right sides of the outer sidewall of the sealing pipe, a drain port is evenly distributed around the left and right sides of the outer sidewall of the connecting pipe, a first filter screen is fixedly connected to the inner cavity wall of the connecting pipe, a second filter screen is fixedly connected to the inner cavity wall of the connecting pipe and located to the right of the first filter screen, and a limit ring is fixedly connected to the outer sidewall of the connecting pipe and located outside the rotating ring.

[0006] Preferably, a pump body is fixedly connected to the top right side of the base, an inlet pipe is provided on the right side of the pump body, the inlet pipe is connected to the connecting pipe through a flange, and an outlet pipe is provided on the rear side of the pump body.

[0007] Preferably, an installation shaft is rotatably connected between the left and right sides of the inner cavity of the pump body, and an impeller is fixedly connected to the outer wall of the installation shaft, and the impellers are evenly distributed.

[0008] Preferably, a motor is fixedly connected to the top left side of the base, and a coupling is fixedly connected to the power output shaft end of the motor through a flange. The mounting shaft is connected to the coupling through the flange.

[0009] Preferably, the through holes and the drain outlets are staggered, and the inner diameters of the through holes and the drain outlets are equal.

[0010] Preferably, a guide head is fixedly connected to the right side of the first filter screen, the guide head extends into the interior of the second filter screen, and the first filter screen and the second filter screen are funnel-shaped.

[0011] Preferably, the first filter screen is located to the left of the left drain outlet, and the second filter screen is located to the left of the right drain outlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This mixed-flow pump with a multi-stage filtration structure has a connecting pipe installed on the inlet pipe of the pump body, and a drain port is provided on the outside of the connecting pipe. The drain port is sealed by a sealing pipe and a sealing ring. The sealing pipe has a through hole of the same size as the drain port. The filter is filtered once by a funnel-shaped second filter screen, and then filtered a second time by a first filter screen. The filtered impurities accumulate at the intersection of the outside of the filter screen and the inside of the connecting pipe. Rotating the sealing pipe makes the through hole overlap with the drain port. When the pump is running, the filtered impurities are discharged by the water flow. This allows for effective filtration by the filter screen and makes it easier to clean the impurities, saving time and effort while improving cleaning efficiency. Attached Figure Description

At the same time, the installation shaft 113 drives the impeller 114 to rotate.

[0024] Please refer to it again. Figure 1-5 A rotating ring 210 is rotatably connected to the left and right sides of the outer wall of the connecting pipe 200. A sealing pipe 211 is fixedly connected between the inner walls of the rotating ring 210, and the sealing pipe 211 is sleeved on the outside of the connecting pipe 200. A sealing ring 212 is embedded in the left and right sides of the inner wall of the sealing pipe 211. Through holes 213 are evenly distributed around the left and right sides of the outer wall of the sealing pipe 211. Drainage ports 220 are evenly distributed around the left and right sides of the outer wall of the connecting pipe 200. A first filter screen 230 is fixedly connected to the inner wall of the connecting pipe 200, and the inner wall of the connecting pipe 200 is located to the right of the first filter screen 230. A second filter screen 240 is fixedly connected to the side. A limit ring 250 is fixedly connected to the outer wall of the connecting pipe 200 and to the outside of the rotating ring 210. The through hole 213 and the drain port 220 are intersected. The inner diameters of the through hole 213 and the drain port 220 are equal. A guide head 231 is fixedly connected to the right side of the first filter screen 230. The guide head 231 extends into the interior of the second filter screen 240.

The motor 120 is started, and at the same time the motor 120 starts, it drives the mounting shaft 113 to rotate through the coupling 121. At the same time, the mounting shaft 113 drives the impeller 114 to rotate, and the pump body 110 runs to deliver water. During the water delivery process, the funnel-shaped second filter screen 240 performs primary filtration, and under the action of the guide head 231, the first filter screen 230 performs secondary filtration. The filtered impurities accumulate at the intersection of the outer side of the second filter screen 240, the outer side of the first filter screen 230, and the inside of the connecting pipe 200. The sealing pipe 211 is rotated by the rotating ring 210, and under the limit of the limiting ring 250, the through hole 213 overlaps with the drain port 220. When the pump body 110 is running, the water flow removes the filtered impurities and cleans the first filter screen 230 and the second filter screen 240.
