Automatic supporting-floating correcting system for deviation of air cushion belt type conveyor

Abstract

An automatic supporting-floating correcting system for deviation of an air cushion belt type conveyor comprises a supporting-floating air chamber and a conveying belt located above the supporting-floating air chamber. Left deviation correcting air chambers, left deviation correcting pipe banks, right deviation correcting air chambers and right deviation correcting pipe banks are arranged at the portions, located below the conveying belt, inside the supporting-floating air chamber, air inlets of the left deviation correcting air chambers and air inlets of the right deviation correcting air chambers are connected with air inlet hoses extending out of the supporting-floating air chamber respectively, air flow electric adjustment devices are arranged on the air inlet hoses, and air outlets of the left deviation correcting air chambers and air outlets of the right deviation correcting air chambers are connected with air inlets of the left deviation correction pipe banks and air inlets of the right deviation correction pipe banks respectively. Displacement sensors are arranged at the top of the supporting-floating air chamber and used for monitoring left and right deviation of the conveying belt. The automatic supporting-floating correcting system is novel in design, simple in structure, capable of being additionally installed on existing equipment, good in deviation correction effect, high in automation degree, high in practicability and easy to apply and popularize, and the service life of the conveying belt is sufficiently prolonged.

Description

technical field [0001] The invention belongs to the technical field of solid particle material transportation, and in particular relates to an automatic support and buoy correction system for deviation of an air cushion belt conveyor. Background technique [0002] The air-cushion belt conveyor is a widely used short-distance continuous conveying equipment developed at home and abroad in recent years. It is developed on the basis of the roller conveyor. The air is sent into the air chamber, and the air with a certain pressure is sprayed out through the air vent arranged on the air chamber, acting on the lower surface of the conveyor belt, generating buoyancy to the conveyor belt, lifting the conveyor belt up, and the conveyor belt and A stable air film layer is formed between the air chambers to support the conveyor belt and the materials above it, so that the conveyor belt always maintains a certain distance from the air chamber under the action of the air film during the wo...

Problems solved by technology

[0003] In the actual operation of the air cushion belt conveyor, due to various non-human control factors, there is a phenomenon of deviation of the conveyor belt, which causes serious wear on one side of the belt, affects the life of the conveyor belt, increases the operating power, and this phenomenon of deviation is difficult to eliminate

[0004] At present, the commonly used anti-deviation devices for air cushion belt conveyors are mainly a set of vertical clamping rollers installed at both ends of the head and tail of the equipment. The deviation of the belt has a certain strong correction effect, which cannot play any role on the closed conveyor belt, and is limited by the structure of the air-cushion belt conveyor. It is fundamental to add clamping rollers to the middle part to correct the deviation. It's not possible, it's not realistic
