[0027] refer to Figure 1 to Figure 3 , the impeller fastener in this embodiment includes a fastening body 10, based on the edge of the fastening body 10 extending a number of lugs 20, the fastening body 10 is used to fix the impeller 100, the fastening body 10 can be fixed to the impeller At the end face of the impeller 100 , the fastening body 10 and the impeller 100 are relatively fixed, and the fastening body 10 can rotate synchronously with the rotation of the impeller 100 . When the impeller 100 rotates, it can drive the fluid around it to move along the direction of rotation of the impeller 100. Because the extension direction of the lug 20 and the fastening direction of the fastening body 10 to the impeller 100 are opposite to the direction of rotation of the impeller 100, the fluid moves in the same direction as the impeller 100. The lugs 20 contact and apply a force to the lugs 20 opposite to the rotation direction of the impeller 100, so that the rotation trend of t...

[0037] refer to Figure 4 The difference between this embodiment and the first embodiment is that the lug 20 in this embodiment is configured as a piece, and the piece extends outward based on the side of the fastening body 10 , which further simplifies the structure of the lug 20 . In this embodiment, there are three lugs 20 , which are evenly distributed along the edge of the fastening body 10 , extend based on the side of the fastening body 10 , and are flush with the side of the fastening body 10 . Of course, the number of lugs 20 can be appropriately increased. For example, each side of the fastening body 10 is connected with lugs 20; A certain angle, such as being perpendicular to the side of the fastening body 10 , increases the strength of the force applied by the fluid to the lug 20 .

[0038] The sheet body is set as a rigid structure to ensure the effectiveness of motion transmission between the fastening body 10 and the lug 20, so that the resistance exerted by th...

[0041] refer to Figure 6The difference between this embodiment and the first embodiment is that the section of the fastening body 10 is set as a circle, and the lugs 20 are evenly distributed and extend outward based on the edge of the fastening body 10, so as to ensure that the lugs 20 can receive the applied fluid. force. And because the fastening body 10 is circular, the processing is more convenient, and the production efficiency of the impeller fastening device is improved.

[0042] The present invention also provides a conveying device, which includes the above-mentioned impeller fastener, and also includes an impeller 100 and a rotating shaft for driving the impeller 100 to rotate, the impeller fastener is fixed on the end of the impeller 100, and the rotating shaft drives the impeller 100 rotates, so that the impeller fasteners rotate synchronously with the impeller 100. The impeller 100 realizes the delivery of fluid during the rotation process, and the fluid exerts...

Abstract

The invention relates to an impeller fastener, a conveying device and a supercharging device. The impeller fastener comprises a fastening body, wherein a plurality of lugs on the basis of the edge ofthe fastening body are extended out; the fastening body and an impeller are relatively fixed and the fastening body can synchronously rotate along with the impeller; the extending direction of the lugs and the fastening direction of the fastening body to the impeller are opposite to the rotating direction of the impeller; and the conveying device and the supercharging device each comprise the impeller fastener. When the impeller rotates, fluid around the impeller can be driven to flow in the rotating direction of the impeller, and due to the fact that the extending direction of the lugs and the fastening direction of the fastening body to the impeller are opposite to the rotating direction of the impeller, acting force opposite to the rotating direction of the impeller is applied to the lugs when the fluid flows, the movement tendency of the fastening body is opposite to the rotating direction of the impeller, the fastening body rotates in the direction closer to the impeller, the fastening strength of the fastening body to the impeller is increased, loosening of the impeller fastener is avoided, and the normal use of the impeller and the fluid conveying efficiency are prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of fluid conveying or supercharging machinery, in particular to an impeller fastener, a conveying device and a supercharging device. Background technique [0002] As an indispensable transportation method in industrial production, fluid transportation has been widely used in chemical industry, petrochemical industry, textile industry, coating industry and other fields. The impeller is an important part of fluid transportation. The high-speed rotating impeller exerts pressure on the fluid to make the fluid flow and realize fluid transportation. [0003] Usually, the impeller is fixed by locking the impeller on the shaft through the nut, and the rotation of the shaft drives the impeller to rotate at a high speed. In the actual use process, the nut often becomes loose and falls, which affects the stable operation of the conveying machinery, and There will be situations where the impeller is loose and hits the ...
