Abstract
The utility model provides a roller kiln fire distributor, in which the excircle surface plane of a combustion plate for fixing a screw cap is converted into an excircle surface skewed slot. The flow direction of combustion air passing through a cooling air duct is changed; flame in a combustion chamber is driven to pass through a flame guiding hole in a rotary manner to meet the technical requirement of uniform temperature distribution in a kiln body; and the temperature reduction function of the cooling air duct and the combustion plate fixing function are maintained.
Description
Affiliated technical field:
The utility model relates to a kind of fiery device of branch of roller kilns pre-mixing gas combustion burner, especially can change flow direction by the combustion air in cooling air channel, promote flame combustion chamber in rotary manner by leading the flame hole, allow flame evenly distribute, reach the effect of uniformity of temperature profile in the kiln body at the hole wall of leading the flame hole.
Background technology:
At present, the premixed gas burner that uses at roller kilns by premixer, burner plate, burner plate hold-doun nut, combustion chamber, lead the flame hole, the burner plate hold-doun nut leaves the gap and forms the air channel that lowers the temperature with leading between the flame hole.Especially the passage of burner plate is an axial design, the burner plate hold-doun nut is the periphery planar design, the mist that causes combustion gas and combustion air is an axial flow during by burner plate, combustion air is axial flow by cooling during the air channel, the flame of combustion chamber also must be axial flow when leading the flame hole, and the flame of combustion chamber can't enter in the kiln body after hole, flame hole wall evenly distributes leading again.Direct result is: flame can't effectively transmit temperature to the kiln wall by leading hole, flame hole wall, and Yao Qiang limit and kiln central authorities can form the temperature difference, and the product of the product on Yao Qiang limit and kiln central authorities just has aberration, the defect rate height.
Summary of the invention:
For overcome the mixing gas burner of pre existing can not fine solution kiln body in the equally distributed deficiency of temperature, the utility model provides a kind of roller kilns distributor.This roller kilns distributor can not only change the flow direction of combustion air through the cooling air channel, reaches the equally distributed specification requirement of temperature in the kiln body, but also keeps the cooling function in former cooling air channel and to the fixed function of burner plate.
Technical scheme:
The scheme that its technical problem that solves the utility model adopts is: the roller kilns distributor is made of cap body, connection thread, fixed head, cylindrical skewed slot, relate to hold-doun nut, fixed head, cooling air channel skewed slot three parts, cap body left end diameter of bore is the fixed head of burner plate less than cap intracoelomic cavity diameter; The external disc of cap is the cylindrical skewed slot, is the cooling air channel; Cap intracoelomic cavity right-hand member is connected and fixed with the premixer for connecting thread.The burner plate hold-doun nut is made of cap body, connection thread, fixed head, periphery plane.Change outer disk into the cylindrical skewed slot, the fluted shaft line of cylindrical skewed slot and combustion chamber axis angle at 45, the specification of groove is that 5mm * 5mm is a surname, keeps and connects thread, fixed head, promptly keeps former " burner plate hold-doun nut " fixed function to burner plate.
When combustion air enters the combustion chamber by the cooling air channel, the flow direction of combustion air is guided by the cylindrical skewed slot, become axial flow and be 45 ° obliquely flow, the flame that promotes the combustion chamber rotates in leading the flame hole, the flame of rotation just can form the flame of saturation state in leading the flame hole, flame enters in the kiln body after leading the even distribution of hole, flame hole wall again, and flame effectively transmits temperature by leading flame hole inwall to the kiln wall, has reached the equally distributed specification requirement of temperature in the kiln body.
The beneficial effects of the utility model are: under the prerequisite that does not change former fixing and cooling function, allow the combustion air by the cooling air channel change flow direction, promote flame and rotate, reach the equally distributed specification requirement of temperature.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is that the section of burner plate hold-doun nut periphery planar design and combustion air, flame flow are to schematic diagram.
Fig. 2 is that section of the present utility model and combustion air, flame flow are to schematic diagram.
Among the figure 1., the premixer, 2., burner plate, 3., outer disk, 4., the combustion chamber, 5., lead the flame hole, 6., the cooling air channel, 7., the cylindrical skewed slot, 8., fixed head, 9., connect thread, 10., the cap body; A, combustion air illustrate that by the flow direction in cooling air channel B, combustion gas and Air mixing gas are by the flow direction signal of burner plate passage, and C, flame combustion chamber are by leading the flow direction signal in flame hole.
The specific embodiment:
In the embodiment in figure 1, combustion gas and combustion-supporting empty wind enter (B) combustion chamber through burner plate passage 2. and 4. burn after 1. the premixer is mixed into mist.At this moment because also have combustion air 6. to enter the combustion chamber 1. by the cooling air channel, and former burner plate hold-doun nut 3. be the periphery plane design, combustion air along outer disk 3., be parallel to the premixer 1. the direction of axis enter (A) combustion chamber 4..This strand combustion air is after the cooling protection function of 6. finishing through the cooling air channel the burner high temperature resistance; combustion gas is carried out secondary combustion-supporting the time; also combustion chamber flame is 4. formed one and be parallel to the 1. thrust of axis of premixer, 5. flame just enter in the kiln body by leading the flame hole in the mode (C) of axial flow.
In the embodiment of Fig. 2, combustion gas and combustion-supporting empty wind enter (B) combustion chamber through burner plate passage 2. and 4. burn after 1. the premixer is mixed into mist.At this moment, also have combustion air 6. to enter the combustion chamber 1. by the cooling air channel, because 7. 3. the utility model change the periphery plane of former burner plate hold-doun nut into the cylindrical skewed slot, the guiding combustion air along the cylindrical skewed slot 7., with the premixer 1. the direction shape angle at 45 of axis enter (A) combustion chamber 4..This strand combustion air 6. finish cooling protection function through the cooling air channel to the burner high temperature resistance, combustion gas is being carried out secondary combustion-supporting in; also promote combustion chamber flame rotation (C) 4.; make flame lead the flame hole 5. inwall evenly distribute, form and lead the flame hole and enter again in the kiln body after the flame saturation state in 5.; and then by lead the flame hole 5. wall effectively transmit temperature to the kiln wall, satisfied Yao Qiang limit and kiln central authorities temperature equalization specification requirement.
Claims (1)
1. roller kilns distributor, constitute by cap body, connection thread, fixed head, cylindrical skewed slot, it is characterized in that: this product self relates to hold-doun nut, fixed head, cooling air channel skewed slot three parts, and cap body left end diameter of bore is the fixed head of burner plate less than cap intracoelomic cavity diameter; The external disc of cap is the cylindrical skewed slot, is the cooling air channel; Cap intracoelomic cavity right-hand member is connected and fixed with the premixer for connecting thread.
