AI Technical Summary

Problems solved by technology

[0004] Mixed-flow pumps usually transmit chemical substances, and when the pump blade casing inside the mixed-flow pump rotates, impurities and dirt are easily attached to the surface, resulting in a large amount of impurities attached to the surface of the pump blade casing after a long period of use, which can easily cause the pump blades to The rotation speed of the casing is reduced, so that the internal pump blade casing of this kind of mixed flow pump cannot automatically clean the impurities on the surface of the pump blade casing during the rotation process

Embodiment 1

[0028] Embodiment 1: A mixed-flow pump structure and its pump blades, including a mixed-flow pump 1, a pump blade housing 101 rotates inside the mixed-flow pump 1, and an impeller 102 rotates on one side of the pump blade housing 101;

[0029] The pump vane housing 101, the impeller 102 and the mixed flow pump 1 are integrally combined into a mixed flow pump structure. The mixed flow pump can act on the liquid with both centrifugal force and axial thrust, and grooves are embedded on both sides of the pump vane housing 101;

[0030] The inner side of the pump blade housing 101 is provided with a transmission mechanism that can be cleaned automatically. The transmission mechanism includes a rotating disk 2, an axis 201, a bracket 202, a first slider 3, a connecting rod 301, a second slider 302 and a bracket 303, and the bracket 202 Installed inside the grooves on both sides of the pump vane casing 101, the shaft center 201 rotates on one side of the bracket 202, the rotating disk...

Embodiment 2

[0037] Embodiment 2: with reference to instruction manual Figure 5 , 6 and 7, the difference between embodiment 2 and embodiment 1 is that the transmission mechanism includes disc 4, protruding bar 401, gear 5, gear plate 501, rotating shaft 502 and cleaning frame 503, and disc 4 rotates on one end of bracket 202, and the protruding The bar 401 is inlaid on both sides of one end of the disc 4, the tooth piece 501 is rotated and fitted on one end of the convex strip 401, the gear 5 is rotated on the inner side of the tooth piece 501, and the rotating shaft 502 is rotated on the side of the gear 5 away from the tooth piece 501, cleaning The frame 503 slides on the outside of the rotating shaft 502;

[0038] One end of the bracket 202 is separated from the center of the disk 4 by 2-5cm, and each two convex strips 401 form a group. The disk 4, convex strips 401 and tooth pieces 501 are arranged vertically and correspondingly, and the tooth pieces 501 are arranged in a semicircul...

Embodiment 3

[0045] First, centrifugal force is generated when the pump vane housing 101 rotates, so that the first slider 3 slides horizontally inside the pump vane housing 101, and the first slider 3 drives the second slider 302 to slide horizontally through the connecting rod 301, and the second slider 3 slides horizontally inside the pump vane housing 101. 302 slides horizontally on the inside of the rotating disk 2. When the second slider 302 slides to the edge of the inner groove of the rotating disk 2, the rotating disk 2 rotates 360° centering on the axis 201 as a whole. When the rotating disk 2 rotates, it can push One side of the connecting rod 301, the connecting rod 301 can drive the first slider 3 to reciprocate and slide horizontally inside the pump blade housing 101, the rotation of the bracket 202 drives the overall rotation of the disc 4, and the disc 4 rotates with the tooth piece 5 through the convex strip 401 Fitting, and then the gear 501 as a whole swings at an angle, ...

Abstract

The mixed-flow pump structure comprises a mixed-flow pump, a pump blade shell is arranged in the mixed-flow pump in a rotating mode, an impeller is arranged on one side of the pump blade shell in a rotating mode, a transmission mechanism capable of being automatically cleaned is arranged on the inner side of the pump blade shell, and the transmission mechanism comprises a rotating disc, an axis, a support, a first sliding block, a connecting rod, a second sliding block and a support. The support is installed in grooves in the two sides of the pump blade shell, the axis rotates on one side of the support, the rotating disc rotates on the outer side of the axis, the first sliding block slides on the inner side of the pump blade shell, the first sliding block horizontally slides on the inner side of the pump blade shell, and the first sliding block drives the second sliding block to horizontally slide through the connecting rod. The second sliding block horizontally slides on the inner side of the rotating disc, and when the second sliding block slides to the edge of the groove in the inner side of the rotating disc, due to the fact that the rotating disc is arranged in an oval shape, the whole rotating disc rotates by 360 degrees with the axis as the center, the lengths of the rotating discs on the two sides of the axis are different, and therefore one side of the connecting rod can be pushed when the rotating disc rotates.

Description

technical field [0001] The invention relates to the technical field of mixing pumps, in particular to a mixed flow pump structure and pump blades thereof. Background technique [0002] The mixing pump is driven by the internal prime mover to rotate the impeller, which has both centrifugal force and axial thrust on the liquid. It is a combination of centrifugal pump and axial flow pump, and the liquid flows out of the impeller obliquely; [0003] In view of the above-mentioned technical problems in the pump blade casing, it was found through searching that there is a patent number CN202010986971.3, a mixed flow pump with a flow guide device and a height-adjustable base, which has a flow guide device The mixed-flow pump with height-adjustable base can achieve the effect of adjusting the height of the main body of the mixed-flow pump by turning the threaded adjustment rod. the problem of turning together; [0004] Mixed-flow pumps usually transmit chemical substances, and whe...
