Abstract
The utility model discloses an air adjusting device, in particular to a grate air pipe air adjusting device used for the boiler burning device, which comprises an air adjusting plate[2] in an air pipe[1], the air adjusting plate[2] is fixedly connected with an axle[6] with an end extending out of the air pipe[1] and orderly connected with a crank[4] and a positioning pin[3]; wherein, the positioning pin[3] matches positioning holes[7] on a positioning plate[5] fixed at the outer side of the air pipe[1]. The utility model is characterized in that the positioning plate[5] is provided with 11 positioning holes[7] in an arched distribution, and the first 7 positioning holes take angles of 5 DEGs with the neighboring one, and the four positioning holes 7, 8, 9 and 10 take angles of 10 DEGs with the neighboring one, and the positioning holes 10, 11 have an angle of 30 DEGs with each other. The utility model is able to realize a smooth and continuous air adjusting, promising no discontinuity phenomenon, thereby ensuring the complete burning of the fuel.
Description
Technical field:
The utility model relates to a kind of louver, particularly a kind of fire grate airduct louver that is applied in the boiler combustion device.
Background technology:
Burner is an indispensable mechanism in the boiler, can burn fully in order to guarantee fuel, must carry a certain amount of wind by air blast in it, promptly is the passage of air-supply as employed fire grate airduct in the boiler.In use, to regulate air quantity as required, existing louver structure is: (referring to Fig. 1,2) is equipped with turnover air regulating board in the fire grate airduct, air regulating board is fixedly connected with axle, the airduct outside is stretched out in the termination of axle, and connects crank 4 and alignment pin 3, and alignment pin 3 matches with the locating hole 7 that is fixed on the positioning disk 5 of the airduct outside, locating hole 7 is 90 ° of arcs and evenly distributes, and the angle between the adjacent positioned hole 7 is identical to be (15 °).The louver of this structure has the uneven shortcoming of the wind of accent, though locating hole is equally distributed, angle that locating hole rotated of the every setting of crank, alignment pin and air regulating board is identical, but the variation of inner intake is different, it is nonlinear change, inhomogeneous, discontinuous, influence the normal combustion of fuel.
Summary of the invention:
The purpose of this utility model be for a kind of evenly continuously regulate air quantity, be applied to the fire grate airduct louver in the boiler combustion device.
Technical solution of the present utility model is: a kind of fire grate airduct louver, it comprises the air regulating board 2 that is contained in the airduct 1, air regulating board 2 is fixedly connected with axle 6, the airduct 1 outer crank 4 that also connects is successively stretched out in the termination of axle 6, alignment pin 3, alignment pin 3 matches with locating hole 7 on the positioning disk 5 that is fixed on airduct 1 outside, it is characterized in that: 11 locating holes 7 are arranged on the positioning disk 5, curved controlling, being angle between preceding 7 locating hole adjacent holes is 5 °, the 7th, 8,9, being angle between 10 4 locating hole adjacent holes is 10 °, between the 10th and the 11st locating hole institute to be angle be 30 °.
Described airduct [1] is provided with transfers weathercock board 8.
Wind compared with prior art can be realized evenly, be transferred continuously to the utility model, and no out of stock, non-continuous event appearance guarantees the abundant burning of fuel.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is that C shown in Figure 1 is to (prior art) schematic diagram;
Fig. 3 is that C shown in Figure 1 is to (the utility model) schematic diagram.
The specific embodiment: as shown in the figure: 1 is airduct, and the section of airduct 1 is square.Axle 6 is housed on airduct 1, air regulating board 2 is housed in the airduct 16 fixedlys connected, when the axis weight of air regulating board 2 and airduct is straight, airduct is closed, stoped the circulation of air quantity with axle.When parallel with the airduct axis, can open airduct and make the air quantity circulation, the angle difference of its unlatching, air quantity changes to some extent.The airduct outside is stretched out in the termination of axle 6, and crank 4 is housed, alignment pin 3 is equipped with in the termination of crank 4, and be provided with termination that spring makes alignment pin 3 and press in the locating hole 7 on the positioning disk 5 that is fixed on airduct 1 outside, make axle 6 rotate an angle when extracting alignment pin 3 and rotating crank 4, alignment pin 3 is inserted in another locating hole, the air regulating board 2 in the airduct 1 is rotational angle thereupon, the flow of convertible wind again.Described locating hole 7 is not equally distributed.As shown in Figure 3: have 11 locating holes, arc is controlled, and the angle between preceding 7 holes is 5 °, and being angle between the 7th, 8,9,10 4 the locating hole adjacent holes is 10 °, between the 10th and the 11st locating hole institute to be angle be 30 °.When alignment pin 3 is positioned at the 1st locating hole, the air regulating board 2 in the airduct 1 just with the axis normal of airduct 1, be in closed condition.When being positioned at the 11st locating hole, air regulating board 2 is parallel with the axis of airduct 1, is in full-gear.Like this, outside locating hole 7 is not evenly to control, locating hole of every setting, and it is consistent to guarantee that air quantity changes after inner air regulating board 2 rotates, and reaches the linear change of air quantity.The deficiencies in the prior art have been overcome.
On the outside of airduct 1 positioning disk outside, be fixed with an accent label 8, can be carved with number on it, with the front and back order of expression positioning hole corresponding, the convenient wind of transferring.
Claims (2)
1, a kind of fire grate airduct louver, it comprises the air regulating board [2] that is contained in the airduct [1], air regulating board [2] is fixedly connected with axle [6], the outer crank [4] that also connects successively of airduct [1] is stretched out in the termination of axle [6], alignment pin [3], alignment pin [3] matches with locating hole [7] on the positioning disk [5] that is fixed on airduct [1] outside, it is characterized in that: 11 locating holes [7] are arranged on the positioning disk [5], curved controlling, being angle between preceding 7 locating hole adjacent holes is 5 °, the 7th, 8,9, being angle between 10 4 locating hole adjacent holes is 10 °, between the 10th and the 11st locating hole institute to be angle be 30 °.
