Belt circular shape primary forming roller set for annular air cushion circular pipe belt conveyor

Abstract

The invention discloses a belt circular shape primary forming roller set for an annular air cushion circular pipe belt conveyor. The belt circular shape primary forming roller set is composed of six outer concave surface rollers arranged in a hexagonal shape. The outer concave surface rollers are composed of a plurality of polyurethane bearing-inlaid covering wheels with different outer diameters.Due to the adoption of the technical means of combining the six rollers, ensuring that the outer concave surfaces of the rollers make contact with a conveying belt, arranging the plurality of different-outer-diameter polyurethane bearing-inlaid covering wheels, adopting shaft clamp springs for limiting, applying blocking piece type quick fixing, etc., the belt is rounded to enter an inlaying typeair box effectively and is stably isolated from the air box, the technical problems that the belt is poor in roundness, and therefore the wall of a metal pipe scrapes and operation is unstable, etc.are scientifically solved, and the belt is protected to the maximum extent. Due to the arrangement of the outer concave surface rollers and the plurality of different-outer-diameter polyurethane bearing-inlaid covering wheels, the non-synchronization, caused by the difference between the diameters of the outer circles of the rollers, between angular velocity and linear velocity can be avoided, thecontact and friction between the belt and the rollers are reduced, and the service life of the belt is greatly prolonged. A clamping plate type quick installation mode can be adopted to installationand maintenance conveniently.

Description

technical field [0001] The present invention relates to a kind of material conveying equipment, more precisely relates to a kind of ring-shaped air-cushion round tube belt conveyor with primary round roller set. Background technique [0002] Belt conveyor is the most important conveying equipment for bulk materials in contemporary times, mainly used for large-scale and continuous transportation in departments such as coal, mining, metallurgy, chemical industry, construction and transportation. The transported materials are lumpy, granular, powdery, pasty and finished items. [0003] At present, there are the following types of belt conveyors that are used and are being promoted at home and abroad. [0004] (1) Universal belt conveyor: Its main feature is that the rollers are installed on a fixed frame, and the frame is floor-standing; the belt is flat and smooth, and the groove angle of the rollers is 35°. Usually, it is not easy to transport upwards More than 18°, the dow...

AI Technical Summary

Problems solved by technology

The disadvantage is that the conveyor belt runs on the air box in a groove shape, and the material is transported in the open air, which is easy to cause pollution. A single conveyor cannot realize the complex terrain environment, the equipment occupies a large area, there are many leakage points in the air box, and the air energy is seriously wasted.

[0008] To sum up, the existing belt conveyors, especially corrugated sidewall conveyors, tubular belt conveyors and air-cushion belt conveyors have their own advantages and disadvantages, and cannot simultaneously achieve environmental protection, energy saving, high efficiency, and low maintenance. Cost, high adaptability and other requirements

Based on the reality, the inventor designed a ring-shaped air-cushion circular tube belt conveyor for photovoltaic fans, while the belt of ordinary tubular belt conveyors is formed into a round roller group, all of which are arranged in a hexagonal shape with six rollers, squeezed by the middle of the rollers. The pressure belt achieves the effect of forced rounding, but the roundness is not good, which cannot satisfy the rapid cooperation with the inlaid air box formed by the annular air cushion in the early rounding stage to form a stable transportation state
