Description

Combined grinding rotor

Technical Field

The utility model relates to a grinding rotor of sand mill.

Background

With the development of industrialization, the grinding quality of the sand mill is higher and higher. The sand mill is updated continuously and is made to appear like a hundred flowers at the same time, and various types are appeared. Such as a vertical sand mill, a horizontal sand mill, a straight cylinder sand mill or a conical cylinder sand mill, etc. Conventional sand mills are typically fed by mechanical seals, and after high speed agitation grinding of the rotor and grinding media, a separator filters the grinding media and slurry. In general, after the rotor of the sand mill is vertically installed for use, grinding media and slurry are easy to accumulate at the rotor attachment, and the more the grinding media and the slurry accumulate at the position closer to the axis of the main shaft, the grinding media are continuously worn on the main shaft for a long time, and the loss of the rotor shaft is also continuously increased. And because traditional rotor is rotatory at a high speed to send the collision with grinding medium and material, it is not only high that it consumes energy, and it is easy to generate heat moreover, can reduce life.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a can reduce energy consumption, increase of service life's combination formula grinding rotor.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a modular grinding rotor, includes and drives pivoted rotating body by the main shaft, and this rotating body central axis has seted up the installation the shaft hole of main shaft, the shaping has annular cavity in the rotating body top is provided with the top cap of sealed this annular cavity.

Preferably, the upper part of the rotating body is provided with the annular cavity, and the lower end face of the rotating body is provided with a groove.

Preferably, a passage is axially provided between the shaft bore and the annular cavity, the passage communicating with the recess.

Preferably, a stepped hole is formed in the top cover, the main shaft penetrates through an inner hole of the stepped hole and extends into the shaft hole, and an outer hole of the stepped hole is communicated with the passage.

Preferably, the rotating body axial outer wall and the groove inner wall are both provided with a plurality of bar pins.

Preferably, the bottom of the groove is provided with a bottom cover which can be connected with the spindle bolt.

Preferably, the rotating body is conical.

According to the technical scheme, the annular cavity type rotor rotating main body is adopted, so that the weight is light, and the energy consumption can be reduced; meanwhile, the annular cavity is not only favorable for heat dissipation, but also can be used for conveniently arranging cooling equipment, so that the heat generated by the rotating main body is rapidly dissipated, and the service life of the rotor is prolonged.

Detailed Description

The present invention will be described in detail with reference to fig. 1, wherein the exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The utility model provides a combined grinding rotor, which comprises a rotating main body 41 driven by a main shaft to rotate, wherein the rotating main body can be in a conical shape, such as a conical shape with a large upper end and a small end, the conical rotating main body is favorable for forming a conical grinding cavity, and materials are conveniently ground; the center of the rotating main body is axially provided with a shaft hole 42 for mounting the main shaft, and an annular cavity 43 is formed in the rotating main body, so that the rotating main body is light in weight and can reduce energy consumption; meanwhile, the annular cavity is not only favorable for heat dissipation, but also convenient for arrangement of cooling equipment, and ensures that heat generated by the rotating main body is quickly dissipated so as to prolong the service life of the rotor; a top cover 44 is provided at the top end of the rotating body to seal the annular cavity, thereby forming a combined grinding rotor of the rotating body and the top cover, which not only facilitates processing of the rotating body, but also facilitates installation, maintenance and disassembly.

Preferably, the upper part of the rotating body is provided with the annular cavity, and the lower end face of the rotating body is provided with a groove 45, and the groove is designed to further reduce the mass of the rotor and facilitate feeding from the groove at the bottom. And a channel 46 is axially arranged between the shaft hole and the annular cavity and is communicated with the groove, and grinding media flow back through the channel and are recycled, so that the grinding media are prevented from being accumulated near the main shaft for a long time, and the abrasion to the main shaft is reduced. In practice, the passage may be provided directly on the rotating body or on a sleeve on which the spindle is mounted.

In the implementation process, a step hole 47 is formed in the top cover, the main shaft penetrates through an inner hole of the step hole and extends into the shaft hole, and an outer hole of the step hole is communicated with the passage. The material after grinding and grinding medium are at this grinding rotor upside separation back, and grinding medium flows back under the action of gravity extremely outer hole, because the aperture of outer hole is great, can hold more grinding medium, make things convenient for its quick access channel, improve grinding medium's backward flow efficiency. Preferably, the axially outer wall of the rotating body and the inner wall of the groove are provided with a plurality of pins 48 to improve the grinding effect; the bottom of the groove is provided with a bottom cover 49 which can be connected with the spindle bolt, so that the mounting, fastening, maintenance, disassembly and other operations are convenient.

The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
