Abstract
The utility model relates to a coal-fired air heater which comprises a coal furnace, a flue and a draught fan. Heat gathering casings (6) are coated at the outer parts of the coal furnace (1) and the flue. The outer part of the coal furnace and the heat gathering casings form space which is used as an air channel of a blower. The air ports of the blower are arranged on the casings. The length of the flue (5) is four to ten meters. Because the heat gathering casings are used, the utility model has the advantages of full heat utilization, enhanced heat efficiency, low cost and easy manufacture and installation. The cost of the equipment is about 1/4 of an oil burning hot draught fan, and the use cost is about 1/2 of the oil burning hot draught fan.
Description
The utility model relates to a kind of hot blast heating apparatus, relates in particular to a kind of structure that is used for the coal hot-air machine that enclosure space such as booth uses.
Existing be used for the heating apparatus that enclosure space such as booth uses coal furnace arranged, but when using this device, in the canopy heat distribution in space unbalanced, the exhausting waste gas pipeline also can be taken away more heat transfer; And adopt when adding hot oil furnace the cost of equipment cost and use obviously higher.Also have the canopy inner heating device to transmit the device of heat, but its cost is still higher, takes up room again by adopting heat exchangers in series.
The purpose of this utility model is: a kind of coal hot-air machine is provided, is guaranteeing can to improve the thermal efficiency under the low-cost prerequisite of using fuel, and provide that a kind of cost is low, dress is with coal hot-air machine easily.
The purpose of this utility model is achieved in that a kind of coal hot-air machine, comprise coal stove and blower fan composition, it is characterized in that the outer wrap thermal-arrest shell at coal stove, the outside of coal stove and thermal-arrest shell form a space, this space is the air channel of air blast, and shell is provided with the air blast air port.
Operation principle of the present utility model is: because the heat of coal stove wraps up through shell, form the heat build-up space, the heat space in this space is blown out by air blast, forms hot air circulation, can make air uniformly transfer heat in the canopy rapidly, the waste gas of coal stove is discharged outside the canopy by closed conduit simultaneously.
Characteristics of the present utility model are: owing to used the thermal-arrest shell, can make full use of heat, improved the thermal efficiency, and cost be low, manufacturing and easy for installation, equipment cost is about 1/4 of fuel oil air-heater, and use cost is about the fuel oil air-heater half.Very reliable in the use, the situation of heat supply can not take place to stop because of equipment fault.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a structural representation of the present utility model:
As shown in the figure: a kind of coal hot-air machine, comprise coal stove 1 and blower fan 2 compositions, coal stove comprises burner hearth, fuel inlet 3 and air inlet 4, flue 5, at the outer wrap thermal-arrest shell 6 of coal stove and flue, shell is with the iron sheet moulding.The outside of coal stove and thermal-arrest shell form a space 7, and this space is the air channel of air blast, and shell is provided with air blast inlet and outlet 7,8.The loam cake 9 usefulness refractory plates or the metal of burner hearth made among the figure, but can also establish a stockhole at loam cake, for burning, boiling usefulness, will guarantee sealing certainly, prevents exhaust gas leakage.The length of flue 5 is 4-10 rice, and is longer in the horizontal direction, and all with the shell parcel, and then protrude upward waste discharge gas.The horizontal length of the flue of present embodiment is got 6 meters, and also in shell was wrapped to form a space 7, this space was the air channel of air blast, can fully absorb heat.The power of air blast is generally got 150-800W, and present embodiment is got 350W, can guarantee the heating of booth of hundreds of square.
Claims (3)
1, a kind of coal hot-air machine, comprise coal stove, flue and blower fan composition, it is characterized in that the outer wrap thermal-arrest shell (6) at coal stove (1), the outside of coal stove and thermal-arrest shell form a space, this space is the air channel of air blast, and shell is provided with air blast air port (7,8).
2, by the coal hot-air machine of stating of claim 1, the length that it is characterized in that flue (5) is 4-10 rice.
3, by the coal hot-air machine of stating of claim 1, it is characterized in that the burner hearth loam cake (9) of coal stove is made with refractory plate or metal, establish a stockhole at loam cake.
