Description
The utility model relates to drying equipment, and especially a kind of is medium with the hot blast, the equipment that water-containing materials is carried out force drying.
Make the water-containing materials drying mainly contain air dry and two kinds of methods of artificial drying.Among the artificial drying method, be example with the prior art to the drying of wood, method commonly used has boiler super-heated steam drying method; Furnace-heated methods etc., the former investment are big, production cost is high, heat utilization efficiency is low; Though and the latter is simple in structure, the investment is less, owing to lack spray steaming equipment, can not control the temperature and the humidity of dry materials environment in process of production flexibly, the dry mass of product is relatively poor, and initiation fire very easily.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cheap, heat utilization efficiency is high, dry mass is good, safe heated-air drying equipment simple to operate.
The purpose of this utility model can be achieved through the following technical solutions:
The utility model comprises hot-air drying stove and bakery two parts, and hot-air drying stove is made up of upper furnace body, lower furnace body, chimney, water tank, mistake fan housing, blower fan and grate, and the horn mouth of chimney bottom places upper furnace body inside, and chimney passes from water tank; Be provided with the multilayer heating tube in the lower furnace body, form by many heating tubes for every layer, be in series by crossing fan housing between each layer heating tube, be welded with the fixedly maintenance circle of refractory brick and fire clay between each heating tube in lower furnace body, heating tube links to each other by steam spray pipe with water tank bottom; The superiors' heating tube group communicates with upper furnace body and blower fan outlet through ventilation duct.Bakery is because dry chamber, blast pipe, muffler and control valve composition, blast pipe places in the hothouse, and the hothouse top is provided with muffler, and blast pipe links to each other with bottom heating tube in the hot-air drying stove, one end of backwind tube links to each other with fans entrance, before the inlet of blower fan control valve is housed.
Below in conjunction with accompanying drawing and embodiment shown in the drawings, the technical solution of the utility model is described in further detail, but content of the present utility model is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the B-B cutaway view among Fig. 1;
Fig. 4 is the C-C cutaway view among Fig. 3.
The utility model comprises hot-air drying stove and baking room, and hot-air drying stove is made up of upper furnace body 10, lower furnace body 9, chimney 12, water tank 11, mistake fan housing 7, blower fan 13 and grate 4.Be provided with multilayer heating tube 6 in the lower furnace body 9, be made up of many heating tubes 6 for every layer, be in series by crossing fan housing 7 between each layer heating tube, heating tube 6 links to each other by steam spray pipe 8 with the bottom of water tank 11; The superiors' heating tube communicates through the outlet of ventilation duct 16 with upper furnace body 10 and blower fan 13, and the orlop heating tube is connected with air outlet 3.Bakery is made up of hothouse 1, blast pipe 2, muffler 15 and control valve 14.Blast pipe 2 places in the hothouse 1, and muffler 15 is positioned at the top of hothouse 1, and blast pipe 2 links to each other with air outlet 3, and an end of backwind tube 15 links to each other with the inlet of blower fan 13, and control valve 14 is housed before the inlet of blower fan 13.
Above-mentioned blast pipe is 2 wing formula demountable structures; Be welded with the fixedly maintenance circle 5 of refractory brick and fire clay between each heating tube in lower furnace body 9; The horn mouth of described chimney 12 bottoms places upper furnace body 10 inside, and chimney 12 passes from water tank 11.
During the work of this equipment, fuel burn on grate 4, the flue gas of burning generation and be heated after air, heated the air that blasts by blower fan 13 and the cold water in the water tank 11 in the uphill process indirect.The cold air that blower fan 13 blasts after the preheating, enters in the heating tube 6 of lower furnace body 9 in upper furnace body 10, circuitous from top to bottom flowing, and temperature raises gradually, becomes behind the hot blast from air outlet 3 in exhaust duct 2 is diffused into hothouse 1.Hot blast rises to the top of hothouse 1 in the process of dried material, suck through backwind tube 15, blower fan 13 and repeat in the hot-air drying stove to recycle after the heating, and can pass through control valve 14 this moment, realizes the interior outer circulation of hot blast; In addition can be according to the situation in the hothouse 1, open the valve on the steam spray pipe 8, hot water in the water tank 11 just flows into and forms the vaporific globule in the heating tube 6, after heating, become steam and enter in the hothouse 1 after being mixed into damp and hot wind, thereby can control and regulate hothouse 1 interior temperature and humidity with hot blast in the heating tube 6.
The utility model compared with prior art has following outstanding advantage:
1, be provided with the heat exchanger components that is made up of many heating tubes of multilayer in the lower furnace body, the cold air that blower fan blasts exists Circuitous flowing in upper furnace body and the heating tube, long flow path, heat exchange area is bigger, and capable of circulation reusing; Upper stove Body is provided with water tank, but the amount of residual heat will of effective recycling flue gas, and the thermal efficiency and heat utilization efficiency height are baked into This is low.
2, be provided with control valve at backwind tube, both can effectively utilize return air residual heat by adjusting control valve, again can Realize the inside and outside circulation of hot blast, satisfy the requirement of the temperature and humidity in the dry run.
3, be provided with the unit of steam jet that is formed by the water tank that utilizes fume afterheat and steam spray pipe, can control to adjust flexibly Temperature and humidity in the hothouse, and what carry out between hot blast and naked light is indirect heat exchange, thus it is hidden to eliminate fire Suffer from, realize safety work.
4, in lower furnace body, be welded with the maintenance circle, be used for fixing refractory brick and fire clay between the heating tube in the body of heater, be convenient to when changing heating tube, can not damage furnace lining.
5, be provided with fan housing, and when finding the heating tube scaling loss or breaking, only need open fan housing and just can change fast.
6, because blast pipe is a wing formula structure, and dry indoor temperature is even, having a narrow range of temperature between each point can effectively guarantee the baking quality of material.
7, this device structure is simple, reasonable, and usage range is wide, and cost is low.
