A pulverizer sieve with double-sided grooves and holes in the steel plate

Abstract

The invention provides a crusher screen with a double-sided slotted steel plate. The crusher screen is characterized in that one surface of a steel plate with a certain thickness is slotted, the othersurface of the steel plate is also slotted, and the sum of the fractional values of the slotting depth of each surface is 1, thereby realizing hole formation. When the slotted hole is a square hole,the slot in one surface of the steel plate vertically intersects with the slot in the other surface of the steel plate so as to realize hole formation, and edges of two sides are thinned by milling, so that the crusher screen has multiple functions of hole increasing, burbling and crushing.

Description

technical field [0001] The invention relates to the field of pulverizers, in particular to a sieve used in the pulverizer. Background technique [0002] In the field of pulverizer processing, pulverizers have a wide range of applications, and are widely used in industry, agriculture and other fields. Smash etc. The pulverizer accounts for a very large proportion of energy consumption in the production work, because the control of the target particle size of the material is mainly the sieve used by the pulverizer, which is the main reason for the high energy consumption of the pulverizer. For example, in the feed processing industry, the power consumption of the pulverizer accounts for 30-50% of the total energy consumption in the production operation chain. [0003] The improvement of the production performance of the pulverizer has been striving for improvement. In production practice, there are many factors that affect the working efficiency of the pulverizer. In the fi...

Problems solved by technology

[0006] At present, the sieve used in the pulverizer is a round hole sieve punched by a flat plate, which generally has the disadvantage of low opening rate. Because the center of the sieve hole of the round hole sieve is located on the apex of an equilateral triangle, the connection between the three holes The area is larger than the connection area between the two holes, so that it takes up more effective screening area and reduces the opening rate. This is also the inherent feature and disadvantage of the round hole sieve. The connection area is reduced, and the strength of the sieve is weakened at this time, resulting in easy damage and loss of practical value

Because of the smooth surface of the flat plate punching round hole sieve, the friction force generated by the sharp edge on one side during use produces a certain resistance to the moving material, which has a certain enhancement effect on the material's sieve, but the sharp edge wears quickly. , the efficiency of the pulverizer decreases very quickly, which is why the efficiency is high when using a new sieve and then decreases shortly after

It can be seen that the flat punched round hole screen has a low opening rate, does not have the effect of interfering with the circulation layer inside the pulverizer, and does not have the function of crushing the material
