Abstract
The utility model discloses a hot-blast stove with variable-frequency speed control and a controllable air supply amount according to the temperature inside the stove. The hot-blast stove is provided with a stove body. A grate is arranged at the lower portion inside the stove body. A stove door is arranged at the portion, above the grate, of the stove body. An ash discharge door is arranged at the portion, below the grate, of the stove body. A stove chamber is formed above the grate and inside the stove body. A smoke discharge port is formed in the upper end of the stove chamber. A heat exchanger is arranged inside the stove chamber. The heat exchanger is provided with an air inlet and an air outlet. The smoke discharge port is connected with an induced draft fan. The air inlet is connected with an air feeder. A clamping cover communicated with an inner cavity of the heater exchanger is arranged outside the stove body. A temperature transmitter is installed inside the stove body. A variable-frequency speed controller is connected between the temperature transmitter and the air feeder. When the hot-blast stove is used and a coal combustion condition inside the stove chamber is good, the temperature inside the stove chamber is higher, the variable-frequency speed controller can enable a motor of the air feeder to work at a higher rotating speed, and a larger amount of hot-blast air is supplied. When the coal combustion condition inside the stove chamber is poor, the temperature inside the stove chamber is reduced, the variable-frequency speed controller can enable the motor of the air feeder to work at a lower rotating speed, a smaller amount of hot-blast air is supplied, and the air supply amount can be automatically controlled according to the temperature inside the stove.
Description
Technical field
The utility model relates to a kind of coal-fired hot-blast stove, particularly a kind of control device of coal-fired hot-blast stove air output.
Background technology
Coal-fired hot-blast stove is the coal furnace that hot blast can be provided.The hot blast that coal-fired hot-blast stove provides can be used for heating and providing hot blast to be used for dry products to drying equipment to indoor hot blasts that provides such as workshop, factory building, livestock and poultry houses.
Coal-fired hot-blast stove has body of heater, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ashpit is arranged, the fire grate top in the body of heater is burner hearth, there is exhaust opening the upper end of burner hearth, heat exchanger is arranged in the burner hearth, and heat exchanger has air inlet and air outlet, and exhaust opening is connected with air-introduced machine, air inlet is connected with pressure fan, and some body of heater has the chuck that communicates with the inner chamber of heat exchanger outward.
During use, open pressure fan and send into normal temperature air from air inlet, normal temperature air is discharged from air outlet behind heat exchanger cavity and chuck, add coal-fired in from fire door to burner hearth, open id-motor, allow air enter burner hearth through ashpit, make fire coal burning under the condition of fully oxygen supply of fire grate top produce a large amount of heat, fire box temperature raises, heating heat exchanger and chuck, make the hot blast that is heated to form higher temperature through the normal temperature air of heat exchanger cavity and chuck, the hot blast of higher temperature is discharged from air outlet, send to be discharged to workshop, factory building, livestock and poultry houses etc. are indoor, are used for workshop, factory building, indoor heating such as livestock and poultry house, improve workshop, factory building, indoor temperature such as livestock and poultry house, or send in the drying equipment for dry products.
When providing hot blast with above-mentioned coal-fired hot-blast stove, when the coal normal combustion in the burner hearth, the normal air output of blower-use is sent hot blast; When the coal combustion situation in the burner hearth was bad, the temperature in the burner hearth reduced, and needed subnormal air output.In the prior art, the normal air output of pressure fan is changeless, when the temperature of this coal-fired hot-blast stove in burner hearth reduces, can not reduce air output, the electric energy of waste pressure fan.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly can control the frequency control of air output automatically by the hot-blast stove of temperature control air output in the stove according to temperature in the stove.
The utility model is realized with the following method.
Frequency control has body of heater by the hot-blast stove of temperature control air output in the stove, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ashpit is arranged, fire grate top in the body of heater is burner hearth, there is exhaust opening the upper end of burner hearth, heat exchanger is arranged in the burner hearth, heat exchanger has air inlet and air outlet, exhaust opening is connected with air-introduced machine, and air inlet is connected with pressure fan, and body of heater has the chuck that communicates with the inner chamber of heat exchanger outward, temperature transmitter is installed in the stove, is connected with variable-frequency governor between the motor of temperature transmitter and pressure fan.
In the utility model stove temperature transmitter is installed, is connected with variable-frequency governor between the motor of temperature transmitter and pressure fan.The standard electric signal that temperature transmitter can output temperature changes.During use, when the coal combustion situation in the burner hearth is good, temperature in the burner hearth is higher, variable-frequency governor can allow the motor of pressure fan work under high rotational speed, send the hot blast of big air quantity, when the coal combustion situation in the burner hearth was bad, the temperature in the burner hearth reduced, variable-frequency governor can allow the motor of pressure fan work under lower rotating speed, sends the hot blast of less air quantity.
The utility model has continuous temperature transmitter and variable-frequency governor, can control air output automatically according to temperature in the stove.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 cuts open schematic diagram according to the master office of looking of the hot-blast stove of a kind of automatic control indoor temperature of invention scheme proposition of the present utility model.
