Description
Technical field
The utility model relates to a kind of mine drying unit, particularly a kind of device with the microwave drying raw iron ores.
Background technology
Microwave is a kind of electromagnetic wave of very high frequency, and the common radiowave of this electromagnetic energy Ratios is much bigger, and at a touch metal just reflects, and metal can not absorb at all or conduct it; And contain moisture material, microwave not only can see through, its energy can be absorbed on the contrary, is widely used in heating, drying and the drying of food, medicinal material, pesticide pair soil bit product, timber, cardboard, chemical engineering industry product etc.
Existing microwave dryer, comprise frame, travelling belt, rejector, microwave drying oven, microwave source and control system thereof, wherein travelling belt passes the inner chamber of front end rejector, microwave drying oven, rear end rejector successively, and microwave source is positioned at the microwave drying box top.The maximum characteristics of microwave drying be heat on the spot, inside and outside together heating, firing rate is fast, material is inner to be produced heat being heated, so inside and outside together heating, not only temperature is very even, and can not bring half-cooked phenomenon; Simultaneously, because the surface is easier to heat radiation, internal temperature is higher than the outside often, the direction of thermograde direction and the gradation of moisture is identical, conducts heat consistent with the mass transfer direction, impels internal moisture to evaporate rapidly, form the internal pressure gradient, make moisture be diffused into very soon the surface and vapor away.
Because the quick release of moisture, in the microwave drying oven cavity, just there is a large amount of water vapor, can affect equipment work and dry materials effect, therefore, existing microwave dryer sets out the air port at microwave drying oven along a side of travelling belt width direction usually, and the setting dehumidification tube and the air exhauster that are communicated with air outlet.Under the air exhauster effect, air-flow is entered, is discharged by dehumidification tube by two ends rejector opening, thereby the steam in the microwave drying oven is taken out of; Simultaneously, because the rejector air inlet is not smooth, can form local negative pressure at air outlet position, negative pressure is conducive to the moisture evaporation of material, but it is larger that air-flow enters under microwave drying box cavity and the condition of negative pressure flow velocity along the travelling belt direction of transfer, material for fritter, light weight, such as tealeaves, can under airflow function, fly away and intersperse among in the cavity, and then be drawn out of or be attached to microwave drying oven chamber wall and cause peculiar smell even catch fire, if and moisture discharge, dry inadequate problem easily appear again in reduction exhausting air quantity.
During the mine produced, the mode that stoving process in the sample preparation technological process all adopts the electric hot plate heating was got in traditional detection, and this kind mode need to consume a large amount of energy and with heat radiation.Especially there is drawback especially in the oven dry of raw ore, because the raw ore water cut is large and contain a large amount of mud compositions, harden so that in dry run, very easily cause, need operating personnel's sample ore that constantly overturns, increased workman's labour intensity, if carry out the related process such as automatic sampling, auto-drying, automatic pulverizing, automatic division, the ore that hardens will certainly cause the blocking of subsequent technique.
The utility model content
For addressing the above problem, the utility model discloses a kind of device with the microwave drying raw iron ores, simple in structure, easy to use, drying efficiency is high, raw ore dry products steady quality.
The disclosed device with the microwave drying raw iron ores of the utility model, comprise frame, pay-off with travelling belt, be provided with the sampler of sampling wheel and sampling cup, blanking device, feed pipe, be provided with microwave drier and the jaw crusher of dryness storehouse and microwave generating apparatus, described microwave generating apparatus is arranged on the dryness storehouse, described frame has bilevel double-decker, described pay-off and sampler are arranged on the upper strata of frame, described microwave drier and jaw crusher are arranged on frame lower floor, described blanking device is provided with hopper, the inflow point of described hopper is connected to the exit of travelling belt, described sampling cup be arranged on the edge of sampling wheel and the opening direction of sampling cup identical with the sense of rotation of sampling wheel, the discharge end of described hopper is connected to the charging aperture of microwave drier, and the discharging opening of described microwave drier is connected to the charging aperture of jaw crusher by feed pipe.The disclosed device with the microwave drying raw iron ores of the utility model, simple in structure, easy to use, drying efficiency is high, raw ore dry products steady quality, energy consumption is low, has effectively reduced production cost.
The disclosed a kind of improvement of using the device of microwave drying raw iron ores of the utility model, microwave drier also is provided with circulating water cooling device and exhaust tube, the downward exhaust tube of described outlet is communicated to dryness storehouse, and described circulating water cooling device comprises the cooling tube in the exit that is arranged on exhaust tube.Circulating water cooling device and the exhaust tube of this improvement by arranging, outside the timely device for transferring of water vapor that oven dry produces in the device, thereby effectively avoided steam in dryness storehouse, to condense, thereby drying effect and the drying efficiency of equipment have effectively been improved, improve the production efficiency of enterprise, reduced production cost.
The disclosed device with the microwave drying raw iron ores of the utility model, simple in structure, easy to use, drying efficiency is high, raw ore dry products steady quality, ore is difficult for hardening, and energy consumption is low, has effectively reduced production cost, and sampling is convenient, and sample quality is stable, and sampling efficiency is high.
