Description
technical field
The present invention relates to asphalt mixer, be specifically related to the fuel oil heat-conducting oil furnace in asphalt mixer.
background technology
The asphalt mixer adopted at present is moral machine DG3000 type asphalt mixer.The fuel oil heat-conducting oil furnace is heated pitch, residual oil in the asphalt mixer manufacturing process, meets the firing equipment of asphalt mixer need of production.The fuel that heat-conducting oil furnace adopts at present is 0# diesel oil, is light oil, and price is more expensive, causes cost of production higher.In order to adapt to the needs of market economy, according to actual service condition and the own characteristic of mixer, suitable is transformed heat-conducting oil furnace, adopts a kind of cheap fuel, can save production cost.
summary of the invention
The technical problem to be solved in the present invention is to provide the fuel oil heat-conducting oil furnace in a kind of asphalt mixer, and it can adopt the fuel that price is comparatively cheap.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
Fuel oil heat-conducting oil furnace in a kind of asphalt mixer, comprise the oil storage tank that stores heavy bavin, burner, heavy bavin in oil storage tank is offered to the oil supply system of burner and unnecessary heavy bavin is transported to oil storage tank by burner oil return pipe, burner comprises the atomizer of heavy bavin atomization, valve with cutoff function is set on oil return pipe, oil supply system comprises fuel feed pump and is arranged in turn the valve with cutoff function on fuel feed pump, filter the strainer of impurity in heavy bavin, gear oil pump, pressure regulator valve and pressure meter, the oil-in of pressure regulator valve is connected with fuel feed pump with oil-out, the oil return opening of bypass oil return pipe one termination pressure regulator valve, the other end is connected on the fuel feed pump between strainer and gear oil pump, valve with cutoff function is set on the bypass oil return pipe.
Fuel oil heat-conducting oil furnace in above-mentioned asphalt mixer, the injection diameter of the existing atomizer of the injection diameter of atomizer enlarges 1/3.
After the relatively cheap heavy bavin of price filters out impurity via strainer, by the gear oil pump supercharging, the charge oil pressure of pressure meter indication burner, operating personnel adjust pressure regulator valve according to manometric reading charge oil pressure are adjusted into to the required pressure of burner.Occur wearing and tearing in the gear oil pump use procedure, boost performance descends, and just need to adjust charge oil pressure by pressure regulator valve, constant to maintain the burner charge oil pressure.
the accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is principle schematic of the present invention.
In figure: 1 valve, 2 strainers, 3 gear oil pumps, 4 pressure regulator valves, 5 pressure meters, 6 burners, 7 valves, 8 valves, A-B oil supply system, C-D oil return pipe.
The specific embodiment
As shown in Figure 1, fuel oil heat-conducting oil furnace in a kind of asphalt mixer, comprise the oil storage tank, the burner 6 that store heavy bavin, the heavy bavin in oil storage tank offered to the oil supply system A-B of burner and unnecessary heavy bavin is transported to oil storage tank by burner oil return pipe C-D.Burner comprises the atomizer of heavy bavin atomization.Valve 7 with cutoff function is set on oil return pipe.Oil supply system comprises fuel feed pump and is arranged in turn the valve with cutoff function 1 on fuel feed pump, the strainer 2 that filters impurity in heavy bavin, gear oil pump 3, pressure regulator valve 4 and pressure meter 5, and the oil-in of pressure regulator valve is connected with fuel feed pump with oil-out.The oil return opening of bypass oil return pipe one termination pressure regulator valve, the other end is connected on the fuel feed pump between strainer and gear oil pump, and the valve 8 with cutoff function is set on the bypass oil return pipe.
The injection diameter of the existing atomizer of the injection diameter of atomizer enlarges 1/3, to meet the sufficient requirement of heavy bavin atomization.
Pressure regulator valve guarantees that the burner charge oil pressure is constant, makes heavy bavin abundant, stable in the heat-conducting oil furnace internal combustion.For fuel oil can more fully be burnt, require fuel oil impure few as much as possible, strainer can be removed the impurity in fuel oil.
The present invention is easy to use, and failure rate is low is easy to maintenance, and can save greatly cost of production, one ton of bituminous mixture of every production is cost-saved: 3 * (7000-4500)/1000=7.5 unit, and wherein the 0# diesel-fuel price is by 7000 yuan of calculations per ton, and heavy bavin price is by 4500 yuan of calculations per ton.
