Highly effective electromagnetical spiral drying apparatus

Abstract

The invention relates to a high efficient electromagnetic spiral drying device, which is characterized in that: a driving and stirring device comprises a hollow tube distributed from top to bottom; the hollow tube is provided with a spiral blade shaft which is fixed along a tube shaft of the hollow tube; the right end of the spiral blade shaft is respectively connected with bearings of a rear bearing seat (24); the left end of the spiral blade shaft is respectively connected with driving gears; the driving gears are engaged with one another; a discharge port of the hollow tube is communicatedwith a feed port of the hollow tube; an outer layer of the hollow tube is provided with an electromagnetic heating unit formed by wound spiral hollow tubes; a control device controls the driving gearsto rotate in a reverse direction, so as to drive spiral blades to rotate; adhesive wet materials are put into the hollow tube from the feed port of the hollow tube by a feed transmission device; theadhesive wet materials are continuously turned over, stirred, revolved and delivered, is continuously heated at various heating sections for evaporating moisture of the materials; and the heated and dried materials are continuously discharged out of the spiral tubes. The high efficient electromagnetic spiral drying device has the advantages of high heat energy utilization rate, short material drying time, low energy consumption and environment pollution reduction.

Description

technical field [0001] The invention relates to drying and drying equipment for various metal concentrate powders in a washing plant of the non-ferrous metal mining industry, in particular to a high-efficiency electromagnetic spiral drying equipment. Background technique [0002] At present, the drying of various non-ferrous metal concentrates in China generally adopts the original flat iron plate straight kang method, and only a few large enterprises use spiral conveying steam for drying. The existing drying method, the equipment is aging and the energy consumption is high, manual operation is the main method, and the working environment is labor-intensive, especially the drying method of the flat iron plate, because the drying time of the material needs to be shortened at the work site, and the material needs to be kept Mixing will cause dust to fly in the working environment, which not only wastes increasingly scarce resources, but also seriously affects the health of ope...

Problems solved by technology

The existing drying method, the equipment is aging and the energy consumption is high, manual operation is the main method, and the working environment is labor-intensive, especially the drying method of the flat iron plate, because the drying time of the material needs to be shortened at the work site, and the material needs to be kept Mixing, the working environment is full of dust, which not only wastes increasingly scarce resources, but also seriously affects the health of operating staff

The quality of the dried product is unstable, and the moisture content of the material is difficult to control

Whether it is the way of flat iron plate straight kang or the heating source of spiral conveying steam drying, it is coal-fired to transfer heat directly or indirectly, and the utilization rate of heat energy is low. The equipment has long drying time for materials, large energy consumption, and low heat conduction efficiency. The phenomenon of high consumption and low output such as long heating auxiliary time

The soot emitted by the combustion brings serious pollution to the surrounding environment
