High-efficiency drying device for chlorinated paraffin production

Abstract

The invention discloses an effective drying device for chlorinated paraffin production. The effective drying device for the chlorinated paraffin production comprises a drying barrel, a spiral stirrer is vertically arranged in the drying barrel, and a spiral conveyor is transversely arranged at the bottom; a bracket is firmly arranged at the top of the drying barrel, the bracket is downward and firmly connected with at least one vertical reciprocating drive mechanism, and the lower end of the vertical reciprocating drive mechanism is firmly connected with a material scraper; at least one air current inlet is formed in each of the top end and lateral surface of the drying barrel, and the upper end of the spiral conveyor in the drying barrel is transversely provided with a drawable material baffle plate. The effective drying device for the chlorinated paraffin production is complete in drying, high in efficiency and convenient to discharge and scrape material, does not have material bonding phenomenon and eliminates chlorinated paraffin waste, and there is no agglomerated or clumpy shape in competitive products.

Description

technical field [0001] The invention relates to the technical field of chlorinated paraffin production equipment, in particular to a high-efficiency drying device for chlorinated paraffin production. Background technique [0002] Chlorinated paraffin is a chlorinated derivative of paraffin. It has the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It can be used as a flame retardant and an auxiliary plasticizer for polyvinyl chloride. Widely used in the production of cable materials, floor materials, hoses, artificial leather, rubber and other products. And additives used in coatings, lubricating oils, etc. [0003] After the crude chlorinated paraffin is produced and formed, it needs to go through steps such as alkali washing, crushing, filtering and air drying to obtain the fine chlorinated paraffin, and the problem in the drying step is: the chlorinated paraffin after centrifugal filtration is in pieces Or in the shape of aggl...

Problems solved by technology

[0003] After the crude chlorinated paraffin is produced and formed, it needs to go through steps such as alkali washing, crushing, filtering and air drying to obtain the fine chlorinated paraffin, and the problem in the drying step is: the chlorinated paraffin after centrifugal filtration is in pieces Or in the shape of agglomerates, during the drying process, due to the large amount of water in the chlorinated paraffins that are formed into blocks or agglomerates, the drying is not thorough, and the chlorinated paraffins that have not been thoroughly dried are mixed in the fine products, and mold will appear after a long time , metamorphism, which is not conducive to the long-term storage of chlorinated paraffin fine products; secondly, in the existing drying device, due to the presence of moisture in the crude chlorinated paraffin in the drying process, some chlorinated paraffin will be bonded to the oven. On the inner wall of the drying device, if it is not removed in time, it will not only make the inner wall of the drying device thicker and thicker, but also cause more waste of chlorinated paraffin
