[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides an ignition and combustion-supporting device, the working principle of which is to combine a mixing tube, an air regulating valve, an air intake pipe, a nozzle and a burner into a complete ignition and combustion-supporting device, and to adjust the relative position between the nozzle and the air regulating valve to meet the requirements of different gases with different pressures, so as to achieve the purpose of nozzle position adjustment under different gases with different pressures and cost saving.

[0023] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, an ignition and combustion-supporting device comprises a mixing tube, an air damper 2 arranged at the inlet end of the mixing tube, an air intake pipe 3 arranged on the air damper, a nozzle 4 arranged at the head end of the air intake pipe, and a burner 5 arranged at the rear end of the mixing tube;

[0025] The mixing tube includes a truncated cone portion 11, a first columnar portion 12, an inverted truncated cone portion 13 and a second columnar portion 14 which are arranged in sequence from the head end to the tail end, wherein the bottom end of the truncated cone portion is connected to the air damper, the top of the first truncated cone portion is connected to the first columnar portion, and the top diameter of the first truncated cone is consistent with the diameter of the first columnar portion; the bottom end diameter of the inverted truncated cone portion is smaller than the top end diameter of the inverted truncated cone portion, and the bottom end diameter of the inverted truncated cone portion is consistent with the diameter of the first columnar portion, and the top end diameter of the inverted truncated cone portion is consistent with the diameter of the second columnar portion; the burner is arranged at the other end of the second columnar portion.

[0026] The air intake pipe comprises a pipe body 31, a head fixing end 32 arranged at the head end of the pipe body, a tail fixing end 33 arranged at the tail end of the pipe body, and a hollow movable column 34 sleeved on the pipe body and arranged between the head fixing end and the tail fixing end. The movable column can rotate by itself, and the pipe body will not be driven to rotate during the rotation of the movable column.

[0027] The air regulating door is provided with a through hole (not shown) for the air intake pipe to pass through, and the through hole is threadedly matched with the movable column. By rotating the movable column, the air intake pipe can be moved forward and backward, and the position of the nozzle at the end of the air intake pipe in the air regulating door can be adjusted. During the adjustment process, due to the limitation of the movable column by the head fixed end 32 and the tail fixed end, the movable column moves the tube body forward and backward along the straight line where the tube body is located during the self-rotation process, and the self-rotation of the movable column will drive the tube body to rotate, and will not drive the nozzle at the head end of the tube body and the rotation of the external air intake pipe at the tail end, thereby ensuring the normal production. In addition, in order to facilitate the adjustment of the movable part, no external thread is provided on the outer wall of the movable part close to the tail fixed end, and only its surface is roughened, so that the staff can hold this place to realize the rotation of the movable column.

[0028] The specific use steps of the utility model are as follows: Figure 1 and Figure 2 As shown in the figure, in the early stage of commissioning, after the nozzle and the air damper are adjusted and fixed according to the composition and pressure of the incoming gas, there is no need to adjust them again. At this time, the movable part cooperates with the through-hole thread to fix the air intake pipe. The airflow ejected from the gas nozzle guides the air in the atmosphere into the mixing tube, fully mixes with the combustible gas, reaches the burner and then burns stably.

[0029] When the incoming gas is different or a different pressure is required, it can be adjusted again. The air volume can be automatically adjusted to complete the air volume required for combustion. The entire equipment eliminates the use of a pressure regulating valve, which also saves costs.

[0030] Through the above method, the utility model provides an ignition and combustion-supporting device, which integrates a mixing tube, an air damper, an air intake pipe, a nozzle and a burner into a complete ignition and combustion-supporting device, and adjusts the relative position between the nozzle and the air damper to meet the requirements of different gases with different pressures, thereby achieving the purpose of nozzle position adjustment under different gases with different pressures and saving costs.

[0031] The above is only a preferred embodiment of the ignition and combustion-supporting device disclosed in the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all belong to the protection scope of the utility model.
