Description
Technical Field
The utility model relates to the field of impellers, in particular to an impeller protection structure.
Background
In the process of processing raw materials, an impeller is often used, and the raw materials contacted with the impeller are driven to rotate through the rotation of the impeller, so that the kinetic energy of movement is provided for the raw materials;
however, in the process that the impeller drives the raw materials to move, as no effective hard contact exists between the impeller and the raw materials, the friction force between the impeller and the raw materials is small, when the impeller rotates, the raw materials and the impeller are easy to generate differential speed, and at the moment, larger friction is generated between the raw materials and the impeller, so that friction damage is brought to the impeller.
Disclosure of Invention
1. Technical problem to be solved
The utility model aims to solve the problems in the prior art and provide an impeller protection structure which can realize reduction of friction damage caused by different speeds of movement between an impeller and raw materials when the impeller rotates.
2. Technical proposal
In order to solve the problems, the utility model adopts the following technical scheme.
The utility model provides an impeller protective structure, includes the impeller, be provided with detachable pushing plate on the impeller, pushing plate can prevent the wearing and tearing of impeller, in addition when pushing plate wearing and tearing are comparatively serious, can conveniently change.
Further, a plurality of groups of threaded holes are formed in the impeller, through holes are correspondingly formed in each pushing plate, the threaded holes are connected with the through holes through bolts, and the pushing plates are convenient to replace.
Further, the through hole is composed of an outer hole and an inner hole, the diameter of the outer hole is larger than that of the inner hole, the outer hole is arranged in a shape with a large diameter, and the bolt is mainly prevented from protruding out of the pushing plate after being screwed.
Further, the pushing plate is an iron-carbon alloy strip, so that the wear resistance of the pushing plate is improved, and the service life of the pushing plate is prolonged.
3. Advantageous effects
Compared with the prior art, the utility model has the advantages that:
according to the technical scheme, the plurality of pushing plates are arranged on the impeller body to push the raw materials, so that friction damage caused by different speed movement between the impeller and the raw materials can be reduced when the impeller rotates.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic structural view of a pusher plate according to the present utility model;
fig. 3 is a cut-away side view of fig. 2 of the present utility model.
The reference numerals in the figures illustrate:
1. an impeller; 2. a pushing plate; 3. a plate body.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model are within the protection scope of the present utility model.
Example 1:
referring to fig. 1, an impeller protection structure includes an impeller 1, a detachable pushing plate 2 is disposed on the impeller 1, the pushing plate 2 can prevent the abrasion of the impeller 1, and in addition, when the pushing plate 2 is severely abraded, the impeller protection structure can be replaced conveniently.
Referring to fig. 1 and 2, a plurality of groups of threaded holes are formed in the impeller 1, through holes 3 are correspondingly formed in each pushing plate 2, the threaded holes are connected with the through holes 3 through bolts, and the pushing plates 2 are convenient to replace.
Referring to fig. 2 and 3, the through hole 3 is composed of an outer hole and an inner hole, the outer hole has a larger diameter than the inner hole, and is formed in a shape with a large outer hole diameter, mainly preventing the bolt from protruding out of the stripper plate 2 after the bolt is tightened.
The pushing plate 2 is an iron-carbon alloy strip, so that the wear resistance of the pushing plate 2 is improved, and the service life is prolonged.
The working principle is that when in use, the material pushing plate 2 is fixed on the impeller 1 through bolts, and when the follow-up impeller 1 works, the material pushing plate 2 can prevent the impeller 1 from wearing.
The above description is only of the preferred embodiments of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
Claims (2)
