Screen capable of preventing materials from blocking during material processing and self-cleaning method thereof

Abstract

The invention discloses a screen capable of preventing materials from blocking during material processing and a self-cleaning method thereof. The screen comprises rotary shafts, screen sheets which are arranged on the rotary shafts and a motor which drives the rotary shaft to rotate; the screen sheets on the adjacent two rotary shafts are alternately arranged in an interpenetrating mode; gaps between the screen sheets form into channels which are for materials to pass. The self-cleaning method comprises that the materials fall on the channels of the screen, on one hand, cleaning through a hand rubbing mode which is generated by relative movement of the adjacent screen sheets which form into the channels is generated, on the other hand, large materials automatically rotate and turn over in the channels along rotation of the rotary shafts, and accordingly sticky materials on the screen sheets are brought away and a cleaning effect is achieved. According to the screen capable of preventing the materials from blocking during the material processing, self-cleaning is achieved due to the fact that particles in the materials can automatically rotate in the screen, and large particles can stay for a short time and rotate when stay, the above process is similar to a process of hand washing, fine sand is added between palms, the palms are ceaselessly twisted, the sand is added between the palms without stop, and accordingly mud on hands is taken away through the screen.

Description

technical field [0001] The invention relates to a kind of equipment used in the process of material processing, especially a sieve body which can effectively prevent material jamming and realize material self-cleaning, and is specifically applied in material storage, transportation, feeding, sieving In the process of dividing and breaking. Background technique [0002] In the production of industrial materials such as material storage, transportation, feeding, screening, and crushing, there will inevitably be critical particles, moisture, and viscous materials that will adversely affect various links in the process system, typically due to viscosity. The material channel (including sieve holes) of the process system is blocked due to large and large water, which reduces the efficiency of equipment and systems, increases the failure rate, and even stops operation. It requires a lot of manual cleaning and maintenance work, which is different from large-scale The requirements ...

AI Technical Summary

Problems solved by technology

Among these methods, water washing is not suitable for the working conditions where the material needs to reduce moisture, such as coal for kiln; high-pressure gas consumes a lot of energy, and the effect is not ideal; vibration is ineffective for muddy materials with small mass; and scraping and inserting holes The method of medium cleaning will be limited by the size of the hole. If the hole is small, the stiffness and strength of the cleaning element will be too small, the life will be short, and there will be many failures. Moreover, the cleaning element itself will be full of mud, and the cleaning effect will be reduced or even ineffective.
