Description

Automatic coal-fired dryer

Technical field:

The utility model relates to a kind of equipment that material is dried.

Background technology:

At present more to the device category of dry materials, it comprises microwave, the heat transfer of infrared steam, flue gas direct baking, heated-air drying, electrothermal drying, low-pressure low-temperature drying etc., yet its most drying plant is to be divided into fuel oil and two kinds of fire coals substantially.The oil of the primary raw material of its intermediate fuel oil dryer is so operating cost is higher.Though and coal-fired dryer expense is relatively low, must adopt a plurality of oven dry storehouse, very bothersome during the oven dry material, if adopt an oven dry storehouse to discharge problem with the moisture that can't solve in the oven dry storehouse.

Technology contents:

For above-mentioned shortcoming, the utility model provides a kind of automatic coal-fired dryer that adopts an oven dry storehouse can carry out comprehensive drying work.

The utility model is made up of motor, air blast etc., and it mainly is made up of Machine Room and drying chamber two parts, and the Machine Room communicates with air intake vent, surge chamber by air outlet with drying chamber.Coal stove, combustion chamber, heat exchanger, blower fan, baffle plate, coal ash case are arranged in the Machine Room.In the outside, Machine Room coal bin is arranged, the mechanism that delivers coal, motor, air blast, observation panel, humidistat, air inlet.Chimney communicates with the combustion chamber by the heat exchanger inner chamber.Between drying chamber and the surge chamber porous plate is arranged.In the drying chamber outside exhaust outlet and observation window are installed.On dryer, controller can be installed.

The utility model has the advantages that:

1, adopted novel burning coal method, sufficient combustion does not have black smoke, therefore saves coal, and safety reduces labor intensity widely, saves manpower, reduces operating cost.

2, rack and drying chamber have adopted the good colored steel of heat-proof quality, so good heat insulating, preserve moisture temperature humidity requirement in the drying course of assurance different cultivars.

3, heat exchanger is vertically arranged, so coal ash blocking heat-exchanger not, must regularly not remove, and is easy to use.

4, simple to operate, the temperature-controlled precision height is particularly suitable for the demanding occasions of drying technology such as flue-cured tobacco, improves dries quantity greatly.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model A portion partial sectional view.

The specific embodiment:

The utility model is made up of motor 20, air blast 19 etc., and it mainly is made up of Machine Room and drying chamber 7 two parts, and the Machine Room communicates with air intake vent 14, surge chamber 10 by air outlet 4 with drying chamber 7.Coal stove 18, combustion chamber 17, heat exchanger 16, blower fan 3, baffle plate 12, coal ash case 15 are arranged in the Machine Room.The Machine Room is the core of this equipment, under the commander of controller, and each parts co-ordination, finish automatically and deliver coal, air is blown over heat exchanger by blower fan and is heated, and hot-air is sent into drying chamber via the cabinet bottom, enter cabinet top by drying chamber top again, according to this circulation.During damping, open the air inlet baffle plate, extraneous air carries out in the cabinet, discharges moisture from exhaust outlet, reaches the purpose of regulating and controlling humidity.In the outside, Machine Room coal bin 21 is arranged, the mechanism that delivers coal, motor 20, air blast 19, observation panel 13, humidistat 5, air inlet 1.Chimney 2 communicates with combustion chamber 17 by heat exchanger 16 inner chambers.Between drying chamber 7 and the surge chamber 10 porous plate 9 is arranged.In drying chamber 7 outsides exhaust outlet 6 and observation window 8 are installed.On dryer, controller 11 can be installed.

Its course of work is: at first by controller the coal in the coal bin is sent into coal stove by the mechanism that delivers coal, heat energy that produces in the coal stove combustion process and hot cigarette enter the heat exchanger that communicates with the combustion chamber, discharge through chimney again.The air heat that blower fan is blown into through the heat energy and the hot cigarette of over-heat-exchanger, hot-air enters surge chamber by air intake vent, and the hot blast of surge chamber enters by the hole on the porous plate and dries material in the drying chamber, and then gets back in the Machine Room by air outlet, circulate according to this, reach the purpose of oven dry.When the humidity of drying chamber is higher, open baffle plate by humidistat, natural wind just enters in the Machine Room by air inlet, because suction function, the moisture in the drying chamber just can not enter in the Machine Room by air outlet, and is discharged in the atmosphere by exhaust outlet, air inlet openings of sizes can control what of air inlet, advance how many air, discharge identical moisture just accordingly, reduce humidity in the drying chamber with this.Observation panel is to be used for observing the duty of Machine Room and to establish, and observation window is to be used to observe the duty in the drying chamber and to establish.
