Background technology
The biomass thermal wind furnace be a kind of be the equipment of the outside heat supply of fuel with the biomass energy.Biomass fuel is to belong to renewable resource, and its, aboundresources cheap with respect to other fuel price; Thereby the biomass hot water stove is by wide popularization and application.
At present, the biomass thermal wind furnace on the market comprises burner, Heat Room and blower fan.Fuel is in the burner internal combustion.Fuel feeds Heat Room at the hot gas that fuel produces, blower fan is positioned at the side of heat exchanger, this blower fan is as a kind of air inducing equipment, it introduces the hot gas heat exchange that makes in itself and the hot cell with cold air from an end of Heat Room, cold air and hot gas lay respectively in two passages that are not connected, and cold air forms hot gas and drawn by blower fan from the other end of Heat Room after heat exchange.The biomass thermal wind furnace of this structure is all by artificial interpolation fuel, and it operates inconvenience, and automaticity is low.
Summary of the invention
The purpose of this utility model provides a kind of burner for the biomass thermal wind furnace, and it can add biomass fuel automatically.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of burner for the biomass thermal wind furnace, comprise body, grate plate with burner hearth, grate plate is installed in the burner hearth, be provided with air inlet at body, be provided with the air intake dividing plate at air inlet, be provided with deflector below grate plate, the air intake dividing plate matches with deflector and makes gas rush at grate plate; Also comprise for the automatic feeding that fuel is delivered on the grate plate, described automatic feeding comprises spiral follower arm, feed pipe, motor and is used for the controller that the control motor rotates, feed pipe is connected with burner hearth, the spiral follower arm is installed in the feed pipe by bearing, be provided with charging hole in the position between bearing and body on the feed pipe, feed pipe is used for by this charging hole and hopper is connected, the output of spiral follower arm and motor is in transmission connection, and motor and controller are electrically connected.
On the basis of such scheme and as the preferred version of such scheme: described air inlet is connected with feed pipe by air-inducing passage and makes the gas that enters feed pipe rush at burner hearth along the hand of spiral of spiral follower arm.
On the basis of such scheme and as the preferred version of such scheme: the discharging opening position near automatic feeding on body is provided with the fireguard that is inclined to set.
The utility model outstanding and beneficial technical effects compared to existing technology is:
1, the burner for the biomass thermal wind furnace of the present utility model has adopted the structure of automatic feeding, and it makes the biomass fuel in hopper automatically be sent in the burner hearth by automatic feeding, has realized full-automatic feeding.
2, the burner for the biomass thermal wind furnace of the present utility model has adopted the structure of air-inducing passage, makes to break away from fast in automatic feeding by the biomass fuel that is positioned at the discharging opening position, to avoid biomass fuel in the automatic feeding internal combustion.
3, the burner for the biomass thermal wind furnace of the present utility model has adopted the structure of fireguard, and its flame that has intercepted effectively in the burner hearth is scurried in the feed pipe, avoids the biomass fuel in the feed pipe to be ignited.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1;
Burner for the biomass thermal wind furnace of the present utility model acts as a fuel with a kind of new forms of energy and is different from traditional structure, and it has characteristics energy-conservation, that reduce discharging, is the new and high technology that state key is supported.
The burner that is used for the biomass thermal wind furnace that present embodiment provides provides a kind of new fuel supply mode.It comprises body 1, the grate plate 2 with burner hearth 11, and grate plate 2 is installed in the burner hearth 11, is provided with air inlet 12 at body 1, is provided with air intake dividing plate 3 at air inlet 12, is provided with deflector 4 below grate plate 2.The air intake dividing plate matches with deflector and makes gas rush at grate plate, thinks that biomass fuel combustion provides sufficient oxygen, because grate plate has the hole, so oxygen can pass grate plate.Also comprise for the automatic feeding that fuel is delivered on the grate plate, described automatic feeding comprises spiral follower arm 51, feed pipe 52, motor 53 and is used for the controller 54 that the control motor rotates, feed pipe 52 is connected with burner hearth 11, and spiral follower arm 51 is installed in the feed pipe 52 by bearing 55.Helical groove on the spiral follower arm 51 matches with the inner surface of feed pipe 52, and when the spiral follower arm rotated, the biomass fuel that will be positioned at helical groove advanced to the burner hearth direction.Be provided with charging hole 56 in the position between bearing 55 and body 1 on the feed pipe 52, feed pipe 52 is used for by this charging hole 56 and hopper is connected, hopper is used for depositing biomass fuel, because the gravity effect, biomass fuel enters in the feed pipe by charging hole.Spiral follower arm 51 is in transmission connection with the output of motor 53, and namely motor is used for driving the rotation of spiral follower arm.Motor 53 and controller 54 are electrically connected.Controller is used for the time of the rotation time worker starter motor of control motor, makes automatic feeding automatically, supply with biomass fuel to burner hearth quantitatively.
For the biomass fuel of realizing being positioned at the discharging opening position breaks away from purpose in automatic feeding fast, this burner also should be provided with the structure of air-inducing passage, and air inlet 12 is connected with feed pipe 52 by air-inducing passage 6 and makes the gas that enters feed pipe rush at burner hearth along the hand of spiral of spiral follower arm.By this strand air-flow, make that the biomass fuel in the discharging opening position breaks away from this automatic feeding fast.This air-inducing passage can be formed by pipeline independently, also can be combined into by wind isolation board and body.
For avoiding the biomass fuel in the feed pipe to be ignited, this burner also should be provided with the fireguard 7 that is inclined to set, and this fireguard 7 is arranged on the discharging opening position that is positioned on the body 1 near automatic feeding.Be inclined to set, that is to say, the position of this flame-isolating board one end is higher, and the position of an end is lower.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
