A construction method for cleaning the clogged screen hole of vibrating screen

Abstract

The invention discloses a construction method for clearing the blockage of the vibrating screen hole, which comprises the following steps: Step 1: the control system coordinates the regular operation of each component of the driving device, the hammer head hits the screen mesh of the vibrating screen, and the pressure regulator pulls out the spring The medium inside the helical tube and telescopic rod is depressurized, the damping coefficient of the spring helical tube decreases and becomes softer, the thrust of the spring on the support plate and the nut C is reduced, and the vibration efficiency is improved, and the rapid preliminary vibration cleaning is completed for the serious blockage of the screen holes; step 2 : Control the pressure regulator to fill the spring spiral tube and the telescopic rod with medium, boost the pressure, the bolt bounces up under the vibration, the telescopic rod is stretched, and the telescopic rod pumps the medium inside the spring spiral tube to the inside of itself through the connecting pipe, The damping coefficient of the spring spiral tube is reduced, the spring becomes softer and the thrust of the support plate and the nut C is reduced, and the resonance effect of the bolt bouncing upward due to vibration is achieved, which solves the problem of poor resonance effect of the existing spring with a fixed damping coefficient .

Description

Technical field [0001] The present invention relates to a clean-up construction method of a vibrating screen sieve, belonging to the technical field of artificial gravel production. Background technique [0002] In the gravel processing system, the vibrating screen is used, and the vibrating screen mainly grases the material, and the water-containing (fog) in the material of the material is dust-saving, and the water content is water and the needle during the screening process. The sheet material will gradually block the screen, especially when using ≤ 5mm screen sieving fine material; [0003] If the screen is closed, if it is not treated in time, the screening efficiency will be reduced, and the product quality will affect the quality of the product. For the above screen blockage, there are more processing methods in the industry to use more manual cleaning methods, which is sand. After the processing system is idling or downtown, the worker enters the vibrating screen to use t...

Problems solved by technology

[0003] If the screen is not processed in time after the hole is blocked, the screening efficiency will be reduced, and in severe cases, the product quality will be affected. In view of the above-mentioned screen blockage problem, at present, most of the treatment methods in the industry are manual removal, that is, sand and gravel After the processing system is idling or shut down and the vibrating screen is shut down, workers enter the vibrating screen and use a rubber hammer to beat the screen and clean it with a wire brush. If it is a double-layer or multi-layer screen, the distance between each layer of screens is small, and the screen The inclined surface of 15-20o has a lot of dust, the working environment is poor, and the work efficiency is low. Each vibrating screen needs 2 people to clean it for 0.5-2 hours. The labor intensity is high and the efficiency is low; at the same time, when cleaning the screen manually, if Poor communication is very prone to safety accidents, and there are safety hazards;

[0004] Chinese Patent Application No. 2016107521051 discloses a vibrating screen hole blockage cleaning system. Although it solves the above-mentioned problems of manual cleaning, the spring 45 is a spring with a fixed damping force. Long, when the bolt 42 moves up, the spring 45 that fixes the damping force will push it down through the nut C47, and the resonance effect is poor
