Abstract
The utility model relates to a positive-pressure direct-combustion hotblast stove for a baking finish house. The hotblast stove comprises a blast tube 13, a stove body 1, a circulating blower 8, a return duct 12 and a burner 4, wherein the burner 4 is directly arranged in a combustion chamber of the stove body 1; the circulating blower 8 is in a positive pressure type, an air outlet of the circulating blower 8 is connected with an air inlet 6 of the stove body 1; the blast tube 13 is connected with an air outlet 3 of the stove body 1; and a high pressure oxygen supplement blower 5 is arranged at the lower side of the stove body 1. The hotblast stove has the advantages that the flame of the burner directly burns in the circulation air, and the generated heat can directly heat the circulation air without indirect heat exchange; the stove body does not need a stove chamber, therefore, the heat efficiency is high, the temperature rises fast, the effect of energy saving is good, the structure of the stove body is simple, and the cost is low; moreover, the hotblast stove overcomes the defect that the a high temperature resistant blower is required for realizing negative pressure air supply, and the hotblast stove can adopt the normal temperature circulating blower, so as to be economical and practical.
Description
Technical field
The utility model 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, and 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
The technical barrier that the utility model solved 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 utility model 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 utility model 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 the utility model structural representation;
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 utility model 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.
