It is an ideal pump type that absorbs the advantages of centrifugal pumps and axial flow pumps and compensates for the disadvantages of both. The volute mixed flow pump has the characteristics of simple structure and large flow rate. It is widely used in farmland irrigation and drainage, sewage treatment and other fields.

[0003] Although the impeller in the prior art can be driven by an external motor to transport water, there are still some shortcomings. During transportation, smaller impurities will pass through the filter and contact the impeller, and these impurities will collide with the impeller to cause wear of the impeller. Therefore, the impeller needs to be replaced after one end of the impeller is used. The existing method is to heat the impeller and press it into the outer periphery of the motor output shaft, but this installation method is relatively cumbersome and it is not convenient to disassemble the impeller, which increases the labor intensity of employees and reduces the assembly and disassembly efficiency of the impeller. For this reason, a volute type mixed flow pump impeller structure is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a volute mixed flow pump impeller structure, including a frame 1, a motor 2 is fixedly connected to the top of the frame 1, a round rod 3 is fixedly connected to the output end of the motor 2, the other end of the round rod 3 is fixedly connected to a connecting rod 18, the outer side of the frame 1 is fixedly connected to a shell 4, and the round rod 3 and the connecting rod 18 are both located inside the shell 4.

[0032] Reference Figure 4-Figure 7 The outer circumference of the round rod 3 is slidably connected with an impeller 5, and the outer side of the impeller 5 is rotatably connected to two mounting plates 6, one of which is fixedly connected to a compression spring 7 inside one of the mounting plates 6, and a block 8 is fixedly connected to the other end of the compression spring 7, and the block 8 is in contact with the connecting rod 18. By inserting the impeller 5 and the mounting plate 6 into the outer circumference of the round rod 3 and the connecting rod 18, the connecting rod 18 will contact the block 8 when the mounting plate 6 moves. A slot 9 is provided in the middle of the connecting rod 18, and the block 8 and the slot 9 are plugged in and matched. An arc is provided on one side of the block 8 close to the connecting rod 18. Due to the provided arc, the connecting rod 18 can easily squeeze the block 8 and move the block 8 when the block 8 and the connecting rod 18 are in contact, and the compression spring 7 can be compressed when the block 8 moves. When the slot 9 moves to the original position of the block 8, the block 8 can be bounced into the slot 9 under the action of the compression spring 7, so that the impeller 5 can be quickly installed.

[0033] Reference Figure 4 One of the mounting plates 6 is internally slidably connected with a partition, and the partition is fixedly connected between the compression spring 7 and the block 8. The block 8 can be limited by the partition, thereby preventing the block 8 from tilting during movement. At the same time, it can avoid the compression spring 7 from being deformed and squeezed, which may cause deformation and damage to the compression spring 7, thereby increasing the service life of the compression spring 7. A disassembly component is rotatably connected to the middle part of one of the mounting plates 6.

[0034] Reference Figure 5 and Figure 6 The disassembly assembly includes a rotating rod 10, which is rotatably connected to the middle part of one of the mounting plates 6. A pull rope 11 is fixedly connected to the outer side of the rotating rod 10. The other end of the pull rope 11 is fixedly connected to the side of the card block 8 close to the compression spring 7. The pull rope 11 can be reeled in by rotating the rotating rod 10. When the pull rope 11 is reeled in, the card block 8 can be pulled out from the middle part of the card slot 9, so that the impeller 5 can be quickly removed. A roller 17 is rotatably connected to the inside of one of the mounting plates 6. The roller 17 rolls against the pull rope 11. The roller 17 can prevent the pull rope 11 from rubbing against the mounting plate 6 when it moves inside the mounting plate 6, thereby increasing the service life of the pull rope 11.

[0035] Reference Figure 5 and Figure 6A protrusion 12 is fixedly connected to the outer side of the rotating rod 10, and one end of the rotating rod 10 away from the mounting plate 6 is fixedly connected to a limiting block 13, and the other end of the limiting block 13 is fixedly connected to a second compression spring 14. A sleeve 15 is provided on one side of one mounting plate 6, and the limiting block 13 is slidably connected to the middle part of the sleeve 15. The sleeve 15 and the second compression spring 14 are in contact with one end away from the limiting block 13. A limiting groove 16 is provided on the side of the sleeve 15 close to the protrusion 12, and the protrusion 12 and the limiting groove 16 are plugged into each other. A handle is fixedly connected to the end of the sleeve 15 away from the mounting plate 6, and an anti-slip groove is provided on the outer side of the handle. The sleeve 15 can be rotated more effectively and comfortably through the handle and the anti-slip groove.

[0036] Working principle: When in use, the impeller 5 and the mounting plate 6 are inserted into the outer periphery of the round rod 3 and the connecting rod 18. At the same time, when the mounting plate 6 enters, it will squeeze the block 8 and make the block 8 compress the compression spring 7. When the card slot 9 moves to the original position of the block 8, the block 8 can be ejected into the card slot 9 under the action of the compression spring 7, and the impeller 5 can be quickly installed. By rotating the rotating rod 10 and under the action of the pull rope 11, the block 8 and the card slot 9 can be separated, and the impeller 5 can be quickly removed.

[0037] Among them, by pressing the sleeve 15 and under the action of the limit block 13, the compression spring 14 can be compressed, and the protrusion 12 can enter the limit groove 16. At this time, the sleeve 15 can be rotated, and then the sleeve 15 can drive the rotating rod 10 to rotate. By loosening the sleeve 15 and under the action of the compression spring 14, the sleeve 15 can be reset, and then the protrusion 12 can be separated from the limit groove 16. At this time, the rotating rod 10 cannot be rotated, thereby preventing the employee from making a wrong operation during installation, which may cause the mounting plate 6 and the impeller 5 to fall off.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
