Description
Technical field
The utility model belongs to the stove and accessory technical field, particularly a kind of stalk gasification stove that rotates fire grate that has.
Background technology
At present, China rural area is extensive use of the straw gasification burner with environmental protection, characteristics of energy saving, but structurally also exist defective, as under the situation of waste material high humidities such as straw, the inadequate straw ash that burns is piled up at the body of heater center, influence the abundant burning of waste materials such as straw, cause the fuel gas productive rate to reduce.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, the fuel gas productive rate is high has the stalk gasification stove that rotates fire grate.
The purpose of this utility model realizes by following technical proposals.
A kind of stalk gasification stove that rotates fire grate that has of the present utility model, comprise body of heater, bell, air blast, exhaust opening, filter and gas outlet, the top that it is characterized in that described body of heater air outlet is provided with a fire grate mouth, have at this fire grate mouth place one with the described body of heater attaching nut that fixes, one end has externally threaded fire grate bar and is rotatably connected by this nut and body of heater, the top of body of heater is provided with an air guide port, wireway fixes with body of heater by this air guide port and is connected, the other end of wireway fixes with middle purifier and is connected, and purifier fixes with body of heater by carriage and is connected in the middle of this.
Described fire grate is double fire grate, and the external screw thread on the fire grate bar is done tight the connection with the internal thread of described nut, can play the effect of sealing.
Purifier is made up of air guide port, the blowing mouth of middle air guide port below and the staving and taper (or circular arc) bung of bottom discharge mouth in the middle of being provided with in the middle of described, described blowing mouth is connected with filter by appendix, the outer wall on described staving top is welded with the L shaped steel plate of a circle, and the base of taper (or circular arc) bung is connected with the upper bottom surface of L shaped steel plate.
The gas outlet of described wireway is near the top of taper (or circular arc) bung.
The operation principle that has the straw gasification burner that rotates fire grate of the present utility model is:
Under the state of fuel such as straw in anoxic, when in gasification burner, burning, rotate the rotation fire grate and make straw ash all fall into furnace bottom, prevent that straw ash is deposited in the center of gasification burner, influences the abundant burning of fuel such as straw.Because the high humidity of fuel, the water vapour that the heating back produces gas greatly can be by purifier in the middle of the wireway inflow, gas outlet by wireway is ejected on taper (or circular arc) bung of middle purifier, flow in the groove of the L shaped steel plate on the bucket outer wall along taper (or circular arc) bung inwall, the gas of remainder is discharged by discharge outlet because of at the bottom of the gravity effect directly falls into barrel.The pure fuel gas that produces through double purification is input in the filter by appendix.
The utility model has the advantages that: have the straw gasification burner that rotates fire grate and adopted double purification, water vapour is all got rid of, improved the efficiency of combustion of stalk in the body of heater, also improved the productive rate of fuel gas simultaneously; Above body of heater and gas outlet, be provided with smoke exhaust fan, the flue gas that produces can be siphoned away, reduce the flue gas content in the working environment, healthy useful to the user; Air blast and smoke exhaust fan adopt adjustable speed fan, can control the unburnt process of stalk in the body of heater more effectively, thereby further improve the productive rate of fuel gas.
Characteristics of the present utility model are: simple in structure, fuel gas productive rate height, exhaust gas volumn are few.
