Description

Technical Field

[0001] The utility model relates to the technical field of mixed flow pumps, and particularly relates to a new type of mixed flow pump with adjustable flow rate. Background Technique

[0002] A mixed flow pump is a type of pump 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 and lower than that of an axial flow pump. Its head is higher than that of an axial flow pump, but its flow rate is smaller than that of an axial flow pump and larger than that of a centrifugal pump. According to different installation sites, mixed flow pumps are divided into various types, including those with adjustable flow rates.

[0003] Most of the existing flow adjustable mixed flow pumps do not have the function of filtering the water source during pumping. Inevitably, there are garbage such as sludge, fibers, paper, and rags in the water during pumping. If there are more impurities, it is easy to block the flow channel and entangle the impeller, resulting in poor cleaning effect. More seriously, it may cause the motor to burn out, posing a hazard to the staff and reducing the service life of the water pump.

[0004] A mixed flow pump for farmland water conservancy irrigation disclosed in the utility model patent application publication specification CN201721543355.0 of China includes a volute pump body. A support base is installed at the bottom of the volute pump body. An outlet pipe interface is provided at the top of the volute pump body, and an inlet pipe interface is provided on the left side of the volute pump body. Although this mixed flow pump for farmland water conservancy irrigation is convenient for initially filtering larger impurities and effectively improves the filtering efficiency, it has the disadvantage that it is inconvenient to quickly collect the impurities filtered by the device and clean and maintain the filtering mechanism inside the mixed flow pump after filtering the impurities. Content of the Utility Model

A rotating rod is arranged inside the suction pipe, and the rotating rod is fixedly connected to an impeller inside the pump body. A support plate is fixedly connected inside the suction pipe, a filter plate is arranged on the side of the support plate, a through hole adapted to the rotating rod is opened inside the filter plate, a fixed shell is fixedly connected to the side of the filter plate, and a fixing plate is fixedly connected to the side of the fixed shell away from the filter plate.

[0007] Optionally, a motor is fixedly connected to the side of the pump body, and an output shaft of the motor penetrates through the pump body and is fixedly connected to a transmission shaft of the pump body.

[0008] Optionally, a plurality of positioning holes are formed inside the filter plate, and positioning columns adapted to the positioning holes are fixedly connected to the side surface of the support plate.

[0009] Optionally, a screen is fixedly connected inside the fixing plate, and threaded holes are formed inside both the fixing shell and the fixing plate and are threadedly connected with first bolts.

[0010] Optionally, a first turntable is slidably connected to the outer side of the rotating rod, and a plurality of scraping plates are fixedly connected to the outer side of the first turntable.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Embodiment

[0025] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a new type of mixed-flow pump with adjustable flow rate, which includes a pump body 1. A water outlet pipe 3 is connected to the outside of the pump body 1, and a water suction pipe 4 is connected to the outside of the pump body 1. A motor 2 is fixedly connected to the side of the pump body 1. The output shaft of the motor 2 penetrates the pump body 1 and is fixedly connected to the transmission shaft of the pump body 1. A rotating rod 5 is arranged inside the water suction pipe 4. The rotating rod 5 is fixedly connected to the impeller inside the pump body 1. A filter plate 7 is arranged on the side of the support plate 6. A through hole adapted to the rotating rod 5 is opened inside the filter plate 7. A first turntable 13 is slidably connected to the outside of the rotating rod 5. A plurality of scraping plates 14 are fixedly connected to the outside of the first turntable 13. A plurality of support columns 15 are fixedly connected to the side of the first turntable 13. A plurality of first blades 16 are fixedly connected to the outside of the support columns 15. A plurality of cleaning brushes 19 are fixedly connected to the outside of the second turntable 17. A plurality of second blades 20 are fixedly connected to the outside of the second turntable 17. Through the settings of the filter plate 7, the sieve mesh 11, the rotating rod 5, the first scraping plate 14, the first blade 16, the second blade 20, the first turntable 13, the second turntable 17 and the cleaning plate, the device has the effect of filtering and crushing impurities in the water during pumping, effectively solving the problems that there are inevitably sludge, fibers, paper, rags and other garbage in the water when the mixed-flow pump pumps water. If there are more impurities, it is easy to block the flow channel, entangle the impeller, cause the motor 2 to burn out, pose a hazard to the staff and reduce the service life of the water pump.

[0026] During use, connect the water suction pipe 4 to the water source, and then start the motor 2 to make the pump body 1 extract the water source. After the pump body 1 starts, the impeller starts to rotate, so that the rotating rod 5 rotates. After the rotating rod 5 rotates, the first turntable 13 rotates, so that the support columns 15 rotate. After the support columns 15 rotate, the second turntable 17 rotates. At this time, the water source enters the inside of the water suction pipe 4 and enters the inside of the water outlet pipe 3 through the pump body 1. After the water source enters the inside of the water suction pipe 4, the larger impurities in the water source are intercepted by the sieve mesh 11. At this time, the cleaning brush 19 rotates with the second turntable 17 to clean the impurities inside the sieve mesh 11, and the second blade 20 breaks the larger impurities to prevent the larger impurities from closing the sieve mesh 11. Then the first blade 16 breaks the smaller impurities, and the scraping plate 14 completes the cleaning of the filter plate 7. The filter plate 7 thus filters the smaller impurities, effectively solving the problems that there are inevitably sludge, fibers, paper, rags and other garbage in the water when the mixed-flow pump pumps water. If there are more impurities, it is easy to block the flow channel, entangle the impeller, cause the motor to burn out, pose a hazard to the staff and reduce the service life of the water pump. Embodiment

A fixing plate 10 is fixedly connected to the side of the fixed shell 9 away from the filter plate 7. A plurality of positioning holes 8 are formed inside the filter plate 7. A positioning post adapted to the positioning holes 8 is fixedly connected to the side of the support plate 6. A screen 11 is fixedly connected inside the fixing plate 10. Threaded holes are formed inside both the fixed shell 9 and the fixing plate 10 and are threadedly connected with first bolts 12. A second turntable 17 is rotatably connected inside the screen 11. A groove adapted to the support column 15 is formed on the side of the second turntable 17. Threaded holes are formed inside both the second turntable 17 and the rotating rod 5 and are threadedly connected with second bolts 18. Through the settings of the fixed shell 9, the fixing plate 10, the first bolts 12, the second bolts 18, the support plate 6, the positioning holes 8, the second turntable 17 and the rotating rod 5, the device has the effect of quickly disassembling the internal filtering mechanism, and when disassembling, the impurities filtered out by the device can be removed outside the device, effectively solving the problem that it is inconvenient to quickly collect the impurities filtered out by the mixed-flow pump and clean and maintain the internal filtering mechanism of the mixed-flow pump after filtering the impurities.

[0028] During use, rotate the first bolt 12 to make the first bolt 12 disengage from the fixed shell 9 and the fixing plate 10, then rotate the second bolt 18 to make the second bolt 18 disengage from the rotating rod 5 and the second turntable 17, then pull the second turntable 17 to make the second turntable 17 disengage from the rotating rod 5 and the support column 15, then disassemble the fixing plate 10 and the screen 11, then pull the fixed shell 9 to disassemble the filter plate 7, and then the impurities inside the fixed shell 9 can be cleaned, effectively solving the problem that it is inconvenient to quickly collect the impurities filtered out by the mixed-flow pump and clean and maintain the internal filtering mechanism of the mixed-flow pump after filtering the impurities.
