A kind of automatic cleaning and anti-blocking machine for coal foaming chute in coal preparation plant

Abstract

The invention discloses an automatic cleaning and anti-blocking machine for a coal-sprayed chute in a coal preparation plant. , the flexible shaft auger is bent and installed in the inner cavity of the chute, the motor and the upper surface of the chute are movably interspersed and connected, and one end of the flexible shaft auger is connected with the output shaft of the motor, and the coal accumulation sensing device includes a blocking door, a sealing The upper surface of the blocking door and the chute is movably interspersed and connected, the upper surface of the blocking door is fixedly connected with a moving contact, the top of the blocking door is provided with a travel switch, and the upper surface of the travel switch is fixedly connected with a concave holder. The present invention utilizes the setting of the coal deposit cleaning device composed of the coal deposit induction device and the motor and the flexible shaft auger to automatically control the rotation of the flexible shaft auger to clean the blocked coal deposit according to the coal deposit blockage of the chute, so as to ensure the safety of coal in the chute The utility model has the advantages of simple structure, good cleaning effect and low operating cost.

Description

technical field [0001] The invention relates to the field of coal chute transportation, in particular to an automatic cleaning and anti-blocking machine for coal-sprayed chute in a coal preparation plant. Background technique [0002] Coal accumulation in the coal chute of the coal preparation plant is blocked due to high coal moisture or increased friction of the chute, which affects the normal process of washing production. Generally, vibration chute is used to prevent it, but in actual use, The small vibration amplitude of the chute cannot effectively clean the coal deposits attached to the chute, and generally vibrate for 5 seconds every 20 seconds, the electricity cost is high, and the effect is poor. Most of the chutes in the coal preparation plant rely on their own friction to prevent blocking effect even worse Yes, blockage accidents often occur. Contents of the invention [0003] The object of the present invention is to provide an automatic cleaning and anti-clo...
