Description

The hot air grass drying box device

Technical field

The utility model relates to the bake oven device technical field.

Background technology

In industrial production, often to use baking oven or similar bake oven device dries by the fire product, make the moisture of product be subjected to thermal evaporation, final, make people obtain a kind of product of drying, the convenient use is so baking oven is widely used on processing industries such as food, shoes, Lin's grass.Traditional baking oven is a kind of to be to adopt fuel combustion to produce heat to dry product, it as the patent No. 96237016.9 Chinese patent " fuel-firing gas-firing formula far infrared food drying tunnel ", it is made up of at least one baker, above in the baker burner hearth, transmitting chain belt the combustion chamber is housed, its top is heat exchanger plate, the air of heating hot-air channel, the bottom is the far infrared radiation plate, the food upper surface is carried out the heat radiation baking, force hot blast circulation to send to force hot blast that the food lower surface is toasted in the burner hearth by the air-supply plate on warm-air pipe top, be located at the fuel oil type of burner hearth lateral wall or combustion type burner to the burning indoor heating, the method of this indirect, the heat radiation heat is big, capacity usage ratio is low, causes energy consumption cost to rise, if baking oven is excessive, oven temperature does not reach needed 70 degrees centigrade of heating-up temperatures, influences people and normally uses.For this reason, also the someone designs the hot air grass drying box of direct-heating type, it includes the energy heat-insulation and heat-preservation, end face is taken the supplies room of gas port out of, the underrun airflow-distribution board of supplies room is communicated with the hot blast chamber, the hot blast chamber is communicated with the combustion chamber of bake oven device, the top of combustion chamber setting is connected with the fan house that is used to press wind, and slurry oil or coal are normally burnt as the heating thermal source in the combustion chamber, and their defectives are to be easy to generate black smoke, particularly regulate under the improper operational circumstances, this black smoke is more serious, burning slurry oil cost height, deficiency in economic performance, coal combustion also has dust easily, the temperature control performance is poor, has influence on the quality of baking grass, so require further improvement.

Another kind is to adopt Electric heating to come baked goods, as the patent No. is the Chinese patent " combined baking channel " of 02134812.X, it comprises deflector roll, air compartment, it is characterized in that the front portion is the far infrared preheating oven that is provided with many group far infrared electro-thermal tubes, and the rear portion level is associated with at least 2 sections Circulating Air Dry Ovens.In each section Circulating Air Dry Oven, the bottom of the top of film band and baking oven air compartment is provided with the V-type tuyere that the clearance type air outlet is arranged at the V-type bottom, the top of baking oven air compartment, be provided with air heat exchanger, baking oven loam cake middle part is provided with and exports the hot air circulation backflow airduct that is connected on the air intake machine air inlet.Also be provided with and control in far infrared preheating oven and each section Circulating Air Dry Oven programmable controller PLC, the proportion differential temperature controller PID of temperature in the deflector roll transmission speed and baking oven respectively.They no doubt have its progressive one side, but also there is common shortcoming, very nervous as present national energy, a lot of zones exist and lack coal, the situation of short of electricity, on the contrary, there is a large amount of refuses to need to utilize in some industry or zone, as produce mat, the straw-made articles industry of tatami, it needs baking oven to dry Lin's grass on the one hand, as use the baking oven of above-mentioned gas fuel or the baking oven of electricity consumption, and certainly will to expend a large amount of non-renewable the fuel oil energy and electric energy, make the energy of country nervous more, and the manufacturing cost of product is constantly risen, and a large amount of junks that self industry produces such as Lin's grass leftover bits and pieces can't digest, and are thrown away to handle or burn down on the farm, have both caused to waste, contaminated environment also needs us to go to overcome again.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of hot air grass drying box device at existing background technology, and it is simple and reasonable, and processing Lin grass in enormous quantities easily improves crudy, reduces energy expenditure greatly.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of hot air grass drying box device, the supplies room that it includes can heat-insulation and heat-preservation, end face is taken gas port out of, the underrun airflow-distribution board of supplies room is communicated with the hot blast chamber, the hot blast chamber is communicated with the combustion chamber of bake oven device, it is characterized in that being provided with between combustion chamber and the hot blast chamber and be connected with fan house, and, the combustion chamber also is connected with arm on the gas transmission main by control valve and pipeline, and an end of gas transmission main connects gas producer through deduster.

As improvement, be provided with blower fan in the described fan house, the blast of blower fan is at 550 handkerchiefs～650 handkerchiefs, and air quantity is at 20000 meters ³/ hour～25000 meters ³/ hour, adopt the low pressure centrifugal blower, be beneficial to big air quantity air feed, increase the drying room area, reduce the overall baking oven quantity of factory.

As improvement, also be provided with water seal gate valves on the described pipeline, be convenient to sealing, seal the supply of combustion gas, improve security performance.

Improve, described supplies room end face adopts open type again, and unlimited position becomes the gas outlet, reduces gas-flow resistance, is convenient to hot blast and passes through, and is beneficial to the baking grass.

Further improve, described deduster adopts the cyclone separating deduster of band washing again, improves the quality of combustion gas, can avoid the influence to Lin's grass of dust and black smoke basically.

Very important improvement, described gas producer is gas generator or utilizes firewood or the gas producer of forage or fiber or various wooden waste generation fuel gas, particularly adopt firewood or forage or fiber or various wooden waste, turn waste into wealth, can adopt straw-made articles leftover bits and pieces or Lin's grass or timber useless in a large number, wood chip, useless fiber, waste plastics, or all cheap fuel that can burn such as coal cinder, avoid using present the country relatively electric energy and the fuel oil energy of anxiety, reduce energy expenditure greatly, also solved simultaneously straw-made articles waste from a factory problem of outlet, avoid environmental pollution, kill two birds with one stone.

Compared with prior art, advantage of the present utility model is: simple and reasonable, drive a plurality of baking oven work by a gas producer, be more prone in enormous quantities Lin's grass be processed, being fit to factory uses, simultaneously because smokelessly dustless basically, improve crudy, also improve the utilization rate of fuel heat greatly, reduce energy expenditure greatly, good in economic efficiency, good operating stability, the automaticity height is ensured the quality of products easily, and the manufacturing expense of device is low, more preferably, can turn waste into wealth, can adopt straw-made articles leftover bits and pieces or Lin's grass or timber useless in a large number, wood chip, useless fiber, waste plastics, or all cheap fuel that can burn such as coal cinder, avoid the electric energy and the fuel oil energy that use present country relatively more nervous, reduce energy expenditure greatly, simultaneously also solve straw-made articles waste from a factory problem of outlet, killed two birds with one stone, be adapted at the straw-made articles industry, shoes industry or similar other industry.
