Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a pulse-type spraying structure used for boiler pipelines. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. After searching, a Chinese patent document discloses a boiler pulse soot blower [Application No.: 201922071900.6; Publication No.: CN211204084U]. During the use of this pulse soot blower, a strong recoil force will be generated at the moment when the air pump uses the blowpipe to blow soot into the boiler, and there is no connection structure between it and the boiler. The strong recoil force will cause it to topple over; therefore, it is necessary to design a pulse spray structure for boiler pipes. Summary of the invention

[0005] A guide seat is also installed on the frame, and the guide seat is arranged between the two rear wheels. An auxiliary leg is connected to the guide seat in an inclined and sliding manner. A supporting pad is fixed to the end of the auxiliary leg. A locking screw is also threadedly connected to the guide seat.

[0006] The locking screw is a hand-tightened part.

[0007] The material of the limiting block is rubber.

[0008] A handle and an electric control box are installed on the frame, and the air pump is electrically connected to the electric control box through a line.

[0009] The front wheels and the rear wheels are all self-locking universal wheels.

[0010] Compared with the prior art, the pulse injection structure for boiler pipes has the following advantages:

[0011] In the utility model, the air pump is movably connected to the frame, and the rear part of the frame is auxiliary supported by auxiliary legs, so that when the air pump pulses soot through the blowing pipe, the air pump is prevented from tipping over due to a strong recoil force, thereby enhancing the stability of the air pump during operation.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 As shown, the pulse injection structure for boiler pipes includes a frame 1, two front wheels 21 and two rear wheels 20 are installed at the bottom of the frame 1, specifically: the front wheels 21 and the rear wheels 20 are self-locking universal wheels; a vertical plate 11, a bracket 2 and a fixing member 3 are installed on the top of the frame 1 in sequence, the fixing member 3 is rotatably connected to one end of a spring shock absorber 4, and the other end of the spring shock absorber 4 is connected to an air pump 9 through a movable member 5, and a support roller 22 for supporting the air pump 9 is also installed on the bracket 2, and a blowing pipe 8 is fixedly installed on the air pump 9, and the blowing pipe 8 is connected to the air pump 9 through a flange 7 is connected to the connecting pipe 6, and the connecting pipe 6 can be interconnected with the boiler. With this structure, the spring shock absorber 4 can play a certain damping role to reduce the impact of the strong recoil of the air pump 9; a screw rod 13 is also horizontally provided on the vertical plate 11, and a limiting block 10 is installed at the end of the screw rod 13. Specifically, the material of the limiting block 10 is rubber; two locking nuts 12 are threadedly connected to the screw rod 13, and the locking nuts 12 are arranged on both sides of the vertical plate 11.
