Portable cam-type conveying device for breakable granular materials

Abstract

The invention discloses a portable cam-type conveying device for breakable granular materials, and belongs to the technical field of conveying devices. The portable cam-type conveying device comprisesa flexible supporting piece, a conveying hose and a plurality of rotating cam mechanisms distributed at intervals. The flexible supporting piece can be bent horizontally and resists vertical bending,and the conveying hose is fixedly arranged under the flexible supporting piece in a hanging mode through a plurality of flexible hanging pieces distributed at intervals. The rotating cam mechanisms are arranged between the adjacent flexible hanging pieces, rotating cams are fixedly arranged at the bottom of the flexible supporting piece, the upper end of a cam driving belt is slidably arranged onthe periphery of rotating cams in a sleeving mode, and the lower end of the cam driving belt is fixedly connected with the conveying hose. The portable cam-type conveying device not only realizes theautomatic mechanical conveying of the breakable granular materials, but also has almost no damage to the materials and no dust, is especially suitable for the environment with small and complex working space, can be conveniently contracted and hoisted, facilitates the long-distance transportation of the conveying device, can realize the purpose of applying the same device to serve different enterprises, and improves the utilization rate.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment, in particular to a portable cam-type conveying device for easily broken granular materials. Background technique [0002] The chemical industry often uses fragile granular materials as raw materials or catalysts. For example, in the production of sulfuric acid by the contact method, the catalyst for the oxidation reaction of sulfur dioxide is the key to production. Widely used in sulfuric acid production industry. At present, the vanadium catalysts used in industry are based on V 2 o 5 As the active ingredient, alkali metal sulfate (K 2 SO 4 or Na 2 SO 4 ) is a co-catalyst and a multi-component catalyst with diatomaceous earth as a carrier. [0003] The vanadium catalyst is long granular and is fragile. In the converter, after a certain period of operation, it is full of water and SO 2 The impact of the gas gradually reduces its strength and even fragments, leading to a gradua...

Problems solved by technology

Although the positive pressure wind conveying solves the problem of reducing the labor intensity of the work and reducing the time for a single backfill operation, it brings about more other problems: (1) The speed of wind conveying is too fast, and the vanadium catalyst is fragile. During the process, the damage rate of the vanadium catalyst is as high as 20%, which greatly reduces the service life of the vanadium catalyst; (2) the dust in the workshop and the converter is extremely serious, the working environment is extremely harsh, and there are serious dust explosion safety hazards; (3) due to the conversion The operating space inside the converter is narrow and there are many straight pillars in the middle. It is impossible to distribute the vanadium catalyst evenly in the converter by mechanical means, and it can only be manually distributed in the converter. Catalyst dust is too heavy, making it impossible for workers to enter the converter for distributing work; (4) Large power consumption
