Abstract
The invention relates to a positive pressure type direct combustion hot-air furnace for a baking finish house. The furnace provided by the invention comprises an air supply pipe 13, a furnace body 1, a circulating fan 8, an air return tube 12 and a combustion engine 4, wherein the combustion engine 4 is directly arranged in the combustion cavity of the furnace body 1; the circulating fan 8 is a positive pressure type circulating fan, and the air outlet of the circulating fan 8 is connected with the air inlet 6 of the furnace body 1; the air supply pipe 13 is connected with the air outlet 3 of the furnace body 1; and a high-pressure oxygen supplying fan 5 is arranged at the lower side of the furnace body 1. The positive pressure type direct combustion hot-air furnace has the advantages that the flame in the combustion engine is directly burnt in circulating air, the generated heat energy is directly used for heating the circulating air without indirect heat exchange; a furnace liner dose not need to be used in the furnace body, thus the heat efficiency is high, heating is fast, and the energy-saving effect is good; and the structure of the furnace body is simple, and the cost is low. By using the furnace provided by the invention, the defect that a high temperature resistant air feeder needs to be adopted when negative pressure type air supply is carried out is overcome, and a room-temperature circulating fan can be adopted. Thus, the furnace provided by the invention is economical and practical.
Description
Technical field
The present invention relates to the drying plant in the paint line, particularly a kind of combined padding and drying system positive-pressure type direct combustion hot-blast stove, the heat energy that it can produce burning directly exchanges with circulating air, has quick heating, characteristic that the thermal efficiency is high.
Background technology
The machining product of industries such as common engineering machinery, engine, vehicle bridge, its product surface all need carry out baking finish and carry out anticorrosion and decoration, product is in the baking finish process, and operation such as its cleaning, anticorrosion, Puttying, spraying all needs hot-blast stove to dry.Oven dry is the equipment of highly energy-consuming, and the traditional hot wind furnace mostly is suction type indirect thermal wind furnace greatly, complex structure, and the manufacturing cost height, intensification is slow, efficient is low.And must select high temperature resistant blower fan for use, thermal waste is serious.
Summary of the invention
Technical barrier solved by the invention is, overcomes the deficiency that above-mentioned intensification is slow, efficient is low, thermal waste is serious, and a kind of simple in structure, easy to use, energy-conserving and environment-protective, positive-pressure type direct combustion hot-blast stove with low cost are provided.
Technical solution of the present invention is, comprises ajutage 13, body of heater 1, circulating fan 8, backwind tube 12 and combustor 4, and it is characterized in that: combustor 4 directly is arranged in the combustion chamber of body of heater 1; Circulating fan 8 is the positive-pressure type circulating fan, and the air outlet of its circulating fan 8 is connected with the air inlet 6 of body of heater 1; Ajutage 13 is connected with the air outlet 3 of body of heater 1.
The downside of body of heater 1 is provided with high pressure oxygenating blower fan 5.
Be respectively equipped with volume damper 2,14 on ajutage 13 and the backwind tube 12.
Combustor is provided with the control valve group of adjustable fuel gas gas pushing quantity, can regulate the flow of combustion gas more accurately, reaches the temperature in the accurate control drying room.
The filling rock wool was made in the middle of body of heater 1 adopted double-layer plate, and inner panel is a corrosion resistant plate, and outside plate is a cold drawing.
The advantage that the present invention is compared with prior art possessed is:
1. the combustor burned flame directly burns in circulating air, the heat energy that is produced, and directly the heat cycles air need not carry out indirect heat exchange, and body of heater does not need flue, therefore, and thermal efficiency height, quick heating, good energy-conserving effect, and furnace binding is simple, and cost is low.
2. adopt positive-pressure type air-supply design, need adopt the defective of high temperature resistant pressure fan when having overcome the suction type air-supply, can adopt the normal temperature circulating fan, economic and practical.
3. combustor is provided with the control valve group, can regulate the flow of supplying gas of combustion gas more accurately, reaches the temperature of more accurate control drying room;
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
Number in the figure: 1-body of heater, 2-volume damper, 3-air outlet, 4-combustor, 5-high pressure oxygenating blower fan, the 6-air inlet, the 7-damping is flexible coupling, 8-circulating fan, 9-oxygenating air port, 10-peep hole, the 11-access door, 12-backwind tube, 13-ajutage, 14-volume damper, 15-natural gas pipe.
The specific embodiment
The present invention mainly is made up of body of heater 1, circulating fan 8, ajutage 13, backwind tube 12, combustor 4 and high pressure oxygenating blower fan 5.
The filling rock wool was made in the middle of body of heater 1 adopted double-layer plate, and body of heater 1 is provided with oxygenating air port 9, peep hole 10 and access door 11.Peep hole 10 can be torn the formula bolt connecting mode open outside access door 11 adopts for observing flame combustion state, is convenient to maintaining combustor 4 burners and cleaning body of heater 1.Oxygenating air port 9 links with high pressure oxygenating blower fan 5.
Circulating fan 8 is the positive-pressure type circulating fan, and its outlet and the air inlet 6 of body of heater 1 are flexible coupling by damping and 7 are connected, and the air outlet 3 of body of heater 1 is connected with ajutage 13.Be respectively equipped with volume damper 2,14 on ajutage 13 and the backwind tube 12, to guarantee the wind speed in the body of heater 1, in the scope of burner operate as normal.
During work, air enters in the combustion chamber of body of heater 1 from the air inlet 6 of body of heater 1 under the effect of circulating fan 8, after combustor 4 carries out the direct heat exchange, hot-air after the heating behind the air outlet 3 by body of heater 1, the ajutage 14, is sent in the combined padding and drying system again, finishes the baking vanish of workpiece and handles.
The oxygenating pressure of high pressure oxygenating blower fan 5 is greater than the circulating pressure of circulating fan 8, thereby do not produce the phenomenon that flame flows backwards, and guarantees that the natural gas in the body of heater 1 fully mixes with fresh air, and it is more abundant that combustor 4 is burnt.
Owing to adopt positive-pressure type air-supply design, so circulating fan 8 can adopt common circulating fan, and do not need to adopt the high temperature circulation blower fan.
