Description

Impeller for wet-process superfine grinding machine

Technical Field

The utility model relates to a grind the machine technical field, especially relate to a wet process is impeller for superfine grinding machine.

Background

The grinder can make the powder material reach nanometer fineness by a physical mechanical grinding method. Namely dry grinding and wet grinding. The dry grinding refers to grinding with water content not higher than 4%, while the wet grinding is carried out by suspending the raw material in carrier liquid flow for grinding and adding proper auxiliaries such as dispersant to assist grinding. When the water content of the materials exceeds 50 percent in a wet grinding machine, the problem of flying dust can be solved. In food processing, the ground material is often used as a preliminary to leaching, making the ingredients readily available for dissolution, and is therefore well suited to wet grinding. However, wet operation generally consumes more energy than dry operation, and the wear of the equipment is also severe.

In the production design of the wet-process ultrafine grinding machine, a steel impeller is usually adopted, and in the wet-process grinding process, the steel impeller is easy to wear, the shutdown maintenance interval is frequent, and the durability is poor. How to improve and design the impeller to make it possess good wearability becomes the key point of design.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to overcome the deficiency of the prior art, the utility model provides a structural design is reasonable, can effectively improve the impeller wearability, reduces the wearing and tearing to the impeller in the grinding process, effectively reduces the super fine grinding machine impeller of wet process of downtime maintenance time and maintenance cost.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an impeller for wet process superfine grinding machine, sets up in the grinder, and the grinder has the drive shaft, includes the skeleton, the skeleton be disc structure, disc structure center through-hole that has and drive shaft cooperation transmission is connected, disc structure both ends side all the protrusion have protruding muscle, the skeleton except that the surface of through-hole inner wall all covers and has wear-resisting rubber layer.

In the scheme, the wear-resistant rubber layer is arranged on the outer surface of the framework, so that the framework is not in direct contact with materials during wet grinding, and is not easy to wear in the grinding process. The material contacts with the wear-resisting rubber layer when grinding, because the wear-resisting rubber layer has good wear-resisting effect, can effectively reduce the shut down maintenance time, maintain simultaneously only need correspond change wear-resisting rubber layer can, the maintenance cost is lower relatively.

Furthermore, the wear-resistant rubber layer is of a layer structure which is formed on the surface outside the inner wall of the through hole at the framework in an injection molding mode.

Furthermore, for the convenience of cooperation installation, the skeleton both sides terminal surface that corresponds the through-hole position all the protrusion have a boss, it has two at least mounting holes to open on the boss of one of them side end face.

Preferably, the wear-resistant rubber layer is a rubber sleeve coated on the outer surface of the framework, and the rubber sleeve is fixed with the framework through a mounting hole.

Preferably, the end face of each side of the disc-shaped structure is provided with a plurality of convex ribs, the convex ribs are connected between the peripheral surface of the boss and the outer circular surface of the disc-shaped structure, and the convex ribs on the end face of each side of the disc-shaped structure take the center of the disc-shaped structure as the center and are in a spiral structure which is outward spirally.

The beneficial effects of the utility model are that, the utility model provides a super fine grinding machine impeller of wet process, structural design is reasonable, and through designing the wear-resistant rubber layer on the skeleton of impeller, the wear-resistant rubber layer wear resistance is good, can effectively wrap up the skeleton, improves the wear resistance of impeller, is favorable to reducing the shut down maintenance, guarantees production efficiency.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the invention only in a schematic way, and thus show only the components that are relevant to the invention, and the directions and references (e.g., upper, lower, left, right, etc.) may be used only to help describe the features in the drawings. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the claimed subject matter is defined only by the appended claims and equivalents thereof.

The impeller for the wet process ultrafine grinding machine shown in fig. 1 to 3 is a first embodiment of the present invention. The impeller is arranged in a grinding machine, the grinding machine is provided with a driving shaft, and the impeller comprises a framework 1 and a wear-resistant rubber layer sleeved on the outer surface of the framework 1.

The framework 1 is a disc-shaped structure, and a through hole 2 matched with the driving shaft for transmission connection is formed in the center of the disc-shaped structure. The both sides terminal surface that skeleton 1 corresponds through-hole 2 position all protrudes and has boss 3, and it has two mounting holes 4 to open on the boss 3 of one of them side terminal surface. Six convex ribs 5 are arranged on the end face of each side of the disc-shaped structure, the convex ribs 5 are connected between the peripheral face of the boss 3 and the outer circular face of the disc-shaped structure, and the convex ribs 5 on the end face of each side of the disc-shaped structure take the center of the disc-shaped structure as the center and are in a spiral outward spiral structure. The surfaces of the framework 1 except the inner wall of the through hole 2 are all covered with wear-resistant rubber layers. The wear-resistant rubber layer is a rubber sleeve coated on the outer surface of the framework 1, and the rubber sleeve is fastened and fixed with the framework 1 through mounting holes 4 and mounting screws.

The impeller for the wet-process superfine grinding machine is reasonable in structural design, and by designing the wear-resistant rubber layer on the framework 1 of the impeller, the wear-resistant rubber layer is good in wear resistance, the framework 1 can be effectively wrapped, and when the impeller is ground by a wet process, the framework 1 is not in direct contact with materials, so that the impeller is not easy to wear in the grinding process. The material contacts with the wear-resisting rubber layer when grinding, because the wear-resisting rubber layer has good wear-resisting effect, can effectively reduce the maintenance time of shutting down, guarantees production efficiency. During maintenance, only the wear-resistant rubber layer needs to be correspondingly replaced, and the maintenance cost is relatively low.

The utility model discloses newly still have embodiment two. The impeller for the wet-process superfine grinding machine comprises a framework 1 and a wear-resistant rubber layer sleeved on the outer surface of the framework 1. In the second embodiment, the wear-resistant rubber layer is a layer structure which is formed on the surface of the framework 1 outside the inner wall of the through hole 2, so that the framework 1 is prevented from directly contacting with materials, and the abrasion of the framework 1 is effectively avoided.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
