Background technology
The domestic industry process is quickened to advance, and the materials processing development is rapid, and the application of various wood fibres, string, plastic grain, plastics powder, mineral powder, biomaterial, metal-powder more and more widely.
Above material mostly because deposit and the moisture absorption, needs dry processing to use when using before the use, dry general air dry and the special-purpose drying equipment drying of dividing.Air dry big (must be fine) affected by environment and with the weather temperature, humidity, the place is relevant, be subjected to very big restriction, because the influence of air humidity has determined the moisture content of the material of air dry to be difficult to reach below 8%, and the water content requirement of the normal material that uses could used below 2% substantially, some occasion even require moisture content just can use below 0.1%, this just requires material just can reach instructions for use through special-purpose drying equipment, based on above situation and from energy-conservation and angle environmental protection, material adopts earlier through air dry and makes the moisture content of material be lower than 10% and then handle through the method that the drying equipment drying combines and to reach instructions for use mostly.
Existing drying machine divides atmospheric dryer and vacuum drier two big classes.
Atmospheric dryer comprises: throughcirculation dryer, fluidized bed drying machine, pneumatic drier, spray dryer, roller drier, foam-drying agent are worn in box drier, conveyer belt drying machine, canal drier, stirring slot type drying machine, rotary dryer, revolution; Vacuum drier comprises: vacuum box drying machine, the agent of vacuum rotary drying, vacuum are changeed same drier, stirring type dryer, vacuum freeze drier.
Throughcirculation dryer is worn in the main pneumatic drier of drying equipment, stirring slot type drying machine, conveyer belt drying machine, canal drier, rotary dryer, the revolution that are applicable to wood fibre, string, plastic grain, plastics powder, mineral powder, biomaterial, metal-powder industrialization continuous drying at present.These several drying machines are used very wide, shortcoming is that the dry heat mode flame heat that has is that cylindrical shell or air carry out drying to material by medium, safeguard procedures must be very tight, otherwise can be because flame contacts with material and causes danger, and energy waste simultaneously is huge; Have plenty of solid accumulation and dry together and make drying very inhomogeneous, time-consuming take a lot of work expense can, flammable materials can be caught fire because of local heating;
Summary of the invention
The utility model has solved deficiency and the problem that exists in the above-mentioned present technology, and a kind of screw rod drying equipment is provided, and can be widely used in the drying of opaque and cellulosic or bulk material.This equipment utilization screw conveyer material, conveying capacity is stable, and materials overturning is heated evenly; Directly material and screw barrel are heated outward from interior with electromagnetic heater, material is kept fire away; The heated time of adjusting material by screw speed by the moisture content of material carries out drying.Technology is controlled easily, product stable, and energy-saving effect is remarkable, the yield rate height.
The utility model is achieved through the following technical solutions:
Screw rod drying equipment of the present utility model, include transmitting device, the feed system that is connected with transmitting device, transmission system, heat drying system, wherein said transmitting device is the screw transmitting device, form by the screw rod in machine barrel and the machine barrel, the heater of heating system is fixed on the machine barrel inner close fitting at machine tube inner wall, material advances between machine barrel and screw rod uniformly, and by being close to machine tube inner wall heater on every side simultaneously to the material heating, reaches dry purpose.
Screw rod drying equipment of the present utility model, its further technical scheme are that described machine barrel one end top upward opening connects feed system, and the machine barrel other end is used as discharging opening under shed.
Screw rod drying equipment of the present utility model, its further technical scheme can also be that described heating system includes radio-frequency generator and corresponding with it electromagnetic heater, per 2～8 groups of electromagnetic heaters are corresponding exhaust outlet above machine barrel, be provided with pin or short spiral shell rib simultaneously in the screw channel of screw rod, before pin or short spiral shell rib are positioned at each exhaust outlet, exhaust outlet is as discharging steam, pin or short spiral shell rib are arranged as the upset material in the screw channel of screw rod, material is heated evenly, and the steam that upset the time is beneficial in the material is discharged; Further technical scheme is that described screw diameter D is 100～800mm again, and screw rod total slenderness ratio L/D is 16～54; Further technical scheme can also be the wide 0.15D～0.6D of being of described exhaust outlet size again, and length is 0.2D～0.8D, and wherein D is a screw diameter.
The utlity model has following beneficial effect:
Screw rod drying equipment of the present utility model can be widely used in dry opaque and cellulosic or bulk material, owing to adopt screw conveyer, make the highest electromagnetism mode of heating of thermal transition efficient applied to dry industry this with traditional manufacture field, energy consumption reduces by 30～70% during drying material, the energy-saving effect highly significant; Owing to adopt screw conveyer, material and burning things which may cause a fire disaster are isolated fully, reduce the danger of process greatly, better to the combustible material effect.Since adopt screw conveyer, the easier enforcement of insulation measure, and heat loss is littler.Owing to adopt screw conveyer, evenly transmitting material by screw rod, to make material pass through time of the electromagnetism thermal treatment zone constant, homogeneous heating effect stability, the industrial continuous slitless connection of easier realization, the waste in the minimizing personnel and the energy, place.
