Description

Integral horizontal heating furnace for heat-conducting oil

The utility model belongs to firing equipment, particularly can be with the equipment of gas or liquid, suspended solid fuel heating conduction oil.

The current road surface of building, super highway, asphalt concrete pavement and cement concrete pavement are arranged, again based on asphalt concrete pavement, so-called bituminous concrete is exactly to add pitch in the mineral aggregates such as rubble, sand and stone flour to carry out the compound that even mix is made, pitch is a kind of requisite raw material in the compound, and pitch needs when using to be heated to liquid state and to be warming up to more than 160 ℃ from solid-state, and domestic traditional heating means are to use naked light directly to heat, its efficient is low, and is seriously polluted.Another method is a Steam Heating, needs to use large coal-fired boiler, build fixing boiler room, can not change the pitch heating station with the job location.The equipment that adopts conduction oil to conduct heat to heat pitch is abroad arranged, and its heat transfer oil heater is the whole automation equipments by computer control, the cost height, and technical sophistication was domesticly used as yet.

The purpose of this utility model provides a kind of heat transfer oil heater, and it can be a fuel with natural gas, crude oil or coal dust, need not set up the boiler room, be convenient to move, and also simple in structure, implement easily.

Task of the present utility model is achieved in that hot oil furnace is by oven body part, injection assembly, head tank, electric control box is formed, oven body part is made up of outer shroud and interior ring, forms the folder chamber between two rings, falling heat-transfer oil in the folder chamber, heat-insulation layer is posted in the outer shroud outside, the inner tubular burner hearth that forms of interior ring, there is the cover plate of band heat-insulation layer the body of heater front portion, and central authorities are fixed with burner at cover plate.Folder rear, chamber also has oil pipe and hot oil pump import to join, and filter is housed, and below, folder chamber has total return duct to feed.The U-shaped comb also is housed in the burner hearth, and oil pipe joins behind its inlet and the hot oil pump, and outlet feeds the folder thorax.Injection assembly is positioned at body of heater the place ahead, can move forward and backward, and matches with burner during work.Head tank is positioned at the body of heater top, and two parts before and after being divided into communicate with the folder chamber respectively, and forward part communicates with atmosphere, and rear section and atmospheric isolation also are equipped with liquid level indicator, join with non-return valve between two ones.

Voltmeter, power meter, deep fat Pressure gauge are housed in the electric control box.

Operation principle of the present utility model is: natural gas or other fuel are sent into burner combustion through nozzle, flame sprays into burner hearth, the heat energy that burning produces heats up the conduction oil in the folder chamber by radiation, conduction, and gas and moisture content drained into atmosphere by head tank, conduction oil after the dehydration is warming up to temperature required continuously, start the hot oil pump at body of heater rear portion, make conduction oil be drawn to warm oil tank, remove to add heated bitumen by the heat conduction.The conduction oil that has reduced temperature after the heat transfer is back in the body of heater folder chamber through total oil return pipe again, recycles.Sub-fraction in the deep fat that pumps from the folder thorax, from the laggard U-shaped comb to burner hearth of hot oil pump, the raising temperature of being heated once more joins in the conduction oil of folder chamber again, improves the oil temperature to accelerate programming rate.

The utility model is rational in infrastructure, thermal efficiency height; Technology is reliable, and is easy to implement, and the fuel source abundance of using, and can be natural gas, crude oil, heavy oil, diesel oil and coal dust, and used nozzle is to go up the marine products universal product.Improved according to different fuel,, be difficult for causing danger because this stove is an atmospheric pressure kiln, safe and reliable.Burner hearth of the present utility model and heating surface are arranged suitably, are heated evenly, and it is fast to conduct heat, and little to the damage of conduction oil performance, labor strength is low, and what conduction oil was used is YD type oil, and water is more not suitable to the water-deficient area.

Details of the present utility model is described further by following examples and accompanying drawing thereof:

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

With reference to the accompanying drawings, the utility model partly is made up of oven body part, injection assembly part, head tank part, electric appliance control box.Body of heater becomes tubular, comprises body of heater outer shroud 41, interior ring 42, is folder chamber 40 between two-layer that falling heat-transfer oil in the folder chamber 40 is surrounded by heat-insulation layer 21 around the outer shroud 41, and the tubular prosopyle has folder heat-insulation layer 18 between front shroud 17,19, two plates.In the burner hearths that interior ring 42 constitutes U-shaped

comb

4 and 5 are arranged, it is fixed on fixed bar 3 and the support 6, and upper furnace has dividing plate 43, constitutes flue 38, leads to chimney 1.On the cover plate 17,19 of furnace front burner 20 is housed.The rear of body of heater has hot oil pump oil inlet pipe 34 and folder chamber to link, conduction oil filter 23 is arranged on the oil pipe 34, the hot oil pump 25 of two parallel connections, gate valve 27, conduction oil delivery outlet 26,28, behind pump 25, there is oil pipe 24 to enter burner hearth U-shaped comb towards pipe 7, heating once more, enter folder chamber 40 through managing 10 again, the conduction oil after the heat transfer loops back heating furnace folder chamber 40 through total oil return pipe 22.The body of heater seat is on support 12, but integral hoisting.8 is thermal insulation layer among the figure, and 9 is conduction oil, and 11 is the body of heater bearing, and 16 is oil pipe, and 44 is Pressure gauge.
