Portable conveying device for fragile granular material

Abstract

The invention discloses a portable conveying device for a fragile granular material and belongs to the technical field of conveying equipment. The portable conveying device comprises a flexible support part, a conveying hose and a plurality of electromagnetic components distributed at intervals, wherein the flexible support part can be horizontally bent and is resistant to vertical bending; the conveying hose is fixedly hung below the flexible support part through a plurality of flexible hanging parts that are distributed at intervals; the electromagnetic components are arranged between the adjacent flexible hanging parts; and each electromagnetic component comprises an electromagnet fixedly arranged at the bottom of the flexible support part and a soft magnet fixedly arranged at the bottom of the conveying hose. The portable conveying device not only realizes automatic mechanical conveying of the fragile granular material, but also causes almost no damage to the material, avoids raising dust, and is particularly suitable for a complicated environment with a narrow operation space; and the conveying device can be wholly taken up and coiled conveniently for convenient remote transport, and can be applied to and serve for different enterprises, so that the utilization ratio of the portable conveying device is improved.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment, in particular to a portable 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 gradual increas...

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
