The burning heating apparatus also is provided with a control system, coal gas flow and burning strength of the coal gas in the bunter are controlled correctly through a control cabinet, causing the obtained aggregate to satisfying national standard. The utility model is convenient in transportation, wide in applying zones, particularly suitable in construction sites far away from the city e.g. building of freeway, low in manufacturing cost and high in coal utilance.
Description
Technical field
The utility model relates to a kind of heating plant, is meant the combustion heat supplying device in a kind of asphalt mixing plant aggregate drying system specifically.
Background technology
Heating plant in the asphalt mixing plant aggregate drying system mainly contains oil burner, coal-fired combusting device etc.Early stage oil burner mainly is to provide heat to make aggregate drying in the drying drum by burning diesel oil, but this method is because diesel oil is too expensive, and cost is too high and seldom use; At present many heavy oil burners of using instead, but cost is still very high.Coal-fired combusting device, is directly lighted with igniter by coal is ground into fine breeze in low-grade highway some use of constructing, and this method cost is economized than fuel oil, but aggregate temperature is wayward, and coal dust pollutes surrounding environment easily.Can act as a fuel with coal gas in addition, directly from the piped gas in city, extract the energy, but the region that this method is used restriction is more intense, can't implement in the region that does not have town gas, particularly when highway was constructed, the job site was subjected to very big restriction away from the city.
Summary of the invention
The utility model provides a kind of application region extensive, use cost is saved, the combustion heat supplying device that simply is used for asphalt mixing plant aggregate drying system is installed, and this combustion heat supplying device mainly is by the dry aggregate of the burning of the coal gas of gas generator generation.
A kind of combustion heat supplying device that is used for asphalt mixing plant aggregate drying system comprises:
One burner: be made up of burner, igniter, blower fan, blower and pipeline is connected with burner with the required air of supply burning, and burner is used for dry aggregate by the burning of coal gas;
One gas generator: be connected with burner by a gas piping, for burner provides coal gas;
One control system: the gas supply amount and the burner gas-fired intensity that are used for controlling gas generator.
Control system comprises:
One control valve for coal gas: be located at and control gas flow on the gas piping;
One temperature meter: measure dried aggregate temperature;
One flame detector: be located at burner flame place, be used to survey burner and whether burn.Give the alarm if burner fire goes out, and report to switch board, switch board is closed control valve for coal gas immediately.
One switch board: be connected by circuit with control valve for coal gas, blower fan, temperature meter and flame detector, receive the signal that temperature meter and flame detector measure, regulate control control valve for coal gas and blower fan.
The combustion heat supplying device that is used for asphalt mixing plant aggregate drying system that the utility model provides by the coal-fired coal gas that produces of gas generator, is lighted by burner again, and drying drum is given in heat supply, makes the asphalt aggregate drying in the drying drum.
The utility model combustion heat supplying device also is provided with control system, can control the combustion intensity of coal gas in gas flow and the burner thereof exactly by switch board, makes the aggregate that obtains meet national standard.
The utility model device convenient transportation, application region is extensive, is specially adapted to the job site away from the city such as expressway construction, low cost of manufacture, the utilization rate height of coal.
Description of drawings
Fig. 1 is the structural representation of the utility model heating plant.
The specific embodiment
As shown in Figure 1, the heating plant in a kind of asphalt mixing plant aggregate drying system comprises:
A kind of combustion heat supplying device that is used for asphalt mixing plant aggregate drying system comprises:
One burner 2: be made up of burner 5, igniter 6, blower fan 7, blower fan 7 is connected with burner 3 with the required air of supply burning by pipeline, and burner is used for dry aggregate by the burning of coal gas;
One gas generator 1 (Zhejiang Chidaozhu Track Maintenance Machinery Co., Ltd., model is: CMQL3.0, CMQL3.2): be connected with burner 2 by a gas piping 3, for burner 2 provides coal gas;
Gas coal gas producer 1 also can adopt the gas generator of the various models of other company's production, as the unistage type gas generator, and multisection type gas generator or the like.
One control system: the gas supply amount and the burner 2 gas-fired intensity that are used for controlling gas generator 1.
Control system comprises:
One control valve for coal gas 4: be located on the gas piping 3 and control gas flow;
One temperature meter 8: measure dried aggregate temperature, generally select thermocouple for use;
One flame detector 11 (Honeywell Inc., C7027A type): be located at burner 5 flame places, be used to survey burner and whether burn.
One switch board 9: with control valve for coal gas 4, blower fan 7, temperature meter 8,, flame detector 11 is connected by circuit, receives the signal that temperature meter 8 and flame detector 11 measure, and regulates control control valve for coal gas 4 and blower fan 7.
Workflow of the present utility model is as follows: the coal gas that gas generator 1 produces enters combustion pipe 3, pass through control valve for coal gas 4, burner 5 successively, while is input air under 7 effects of the blower fan below the burner 5, mix with air with igniter 7 junction coal gas at burner 5, light mist by igniter 7, light back work, be used for the aggregate in the dry drying drum.
Aggregate is dried the back when discharging opening comes out, measure its temperature and be transferred to switch board that (temperature of aggregate is pressed construction requirement and set by thermal detector 8, error should meet country mark Huaihe River), when aggregate actual temperature and design temperature are not inconsistent, switch board just sends instruction and gives control valve for coal gas 4 and blower fan 7, allow it suitably increase or reduce the influx of coal gas and air, regulate gas-fired intensity, make aggregate temperature meet construction requirement all the time.
Whether can also burn with flame detector 11 real-time detection burners, if burner does not have flame, then give the alarm, and report to switch board 9, switch board 9, guarantee that coal gas does not leak if sending instruction and closing control valve for coal gas 4.
