Grinding miller internal spiral roller

Abstract

The invention discloses a grinding miller internal spiral roller. A center hole is formed in the center of the roll shaft in the axial direction; a spiral groove is formed in the out ring of the roll shaft; a rotating joint is arranged at one end of the roll shaft; a distributive pipe is arranged on one side, close to the rotating joint, inside the center hole of the roll shaft; the clearance between the outer wall of the distributive pipe and the inner wall of the center hole is a backwater passageway; one end of the distributive pipe is communicated with the water inlet of the spiral groove, and a seal structure is arranged between the outer wall of the other end of the distributive pipe and the inner wall of the center hole; a water outlet communicated with one end of the spiral groove is arranged at the center hole, the other end of the spiral groove is communicated with the backwater passageway through a backwater hole, and the tail end of the backwater passageway is communicated with the backwater outlet of the rotating joint. The grinding miller internal spiral roller is reasonable in structure and has the good working performance.

Description

technical field [0001] The invention relates to an inner spiral roller of a grinder. Background technique [0002] The oblique vertical three-roll mill is mainly used for grinding soap granules. The three rolls are arranged obliquely, and the line connecting the center of the section is placed at an angle of 135°. The soap particles on the upper roll squeeze and shear each other on the surface of the roll to achieve grinding. A large amount of heat is generated during the grinding process, and cooling water is required to take away the generated heat. The quality of the cooling effect determines the quality of the soap. [0003] In order to improve the cooling effect, compared with the traditional parallel three-roll mill, the oblique vertical three-roll mill improves the arrangement of the rolls and greatly increases the cooling area. There is little room for increasing the cooling area, and the effect is not good. obvious. [0004] The main body of the traditional roll...

AI Technical Summary

Problems solved by technology

Its main disadvantages: water accumulates under the roller, cold water and hot water are mixed, the heat cannot be exchanged in time, and the cooling effect is reduced; the roller uses more water, and the amount of water stored in the roller is 0.12m3, which requires high water chillers; roller rotation The speed is fast, and the water sloshes inside the roller, resulting in additional resistance when the roller rotates, increasing power consumption; and causing twisting between the roller and the shaft, resulting in premature damage to the roller

On the other hand, there is an increase in the requirements for the roller casting process, which increases the cost

After the outer ring of the roller has been worn for a long time, because the center distance of the matching gear has a small range of change, the roller cannot be used anymore
