Description

Technical Field

[0001] The invention relates to the technical field of taphole opening machines, and in particular to a high-pressure atomizer for taphole opening machines. Background Art

[0002] The taphole opener is a key piece of equipment in front of a blast furnace. Its function is to open the taphole at a certain angle, allowing molten iron to flow smoothly out of the channel. Blast furnace tapholes tend to be deeper and harder, and the taphole opener operates at high temperatures and generates large amounts of dust, causing environmental pollution. The taphole opener's related working components need to be cooled and dust-free. Currently, when this problem arises, a high-pressure purge mist generated by atomizing a mixture of water and gas is typically used. However, the atomization effect is often poor, and the water mist purge coverage is incomplete, making it difficult to achieve the desired effect. Summary of the Invention

[0003] The object of the present invention is to provide a high-pressure atomizer for a taphole opening machine to solve the problems encountered in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-pressure atomizer for a tapping machine, comprising a shell and a high-pressure air pipe, a high-pressure water inlet pipe being arranged on the shell, the high-pressure air pipe being rotatably arranged in the shell, one end of the high-pressure air pipe extending out of the shell and provided with a nozzle, a plurality of push plates being arranged on the circumference of the outer wall of the high-pressure air pipe corresponding to the high-pressure water inlet pipe, a plurality of through holes being arranged on the wall of the high-pressure air pipe between the push plates, and the high-pressure water inlet pipe being inclined toward the push plates.

[0005] As a preferred embodiment of the present technical solution, the housing and the high-pressure gas pipe are coaxially arranged.

[0006] As a preferred embodiment of the present technical solution, an annular limiting groove is provided on the inner wall of the shell, an annular convex strip matching the annular limiting groove is provided on the outer wall of the high-pressure air pipe, a steel ball is provided at the bottom of the annular limiting groove, and the annular convex strip is limited in the annular limiting groove by the rolling of the steel ball.

[0007] As a preferred embodiment of the present technical solution, the nozzle is in a cone shape with a larger inner portion and a smaller outer portion, and nozzle holes are provided on the side wall and the outer end portion of the nozzle.

[0008] As a preferred embodiment of the present technical solution, the inclination angle of the high-pressure water inlet pipe is 30-50 degrees.

[0009] Compared with the prior art, the present invention delivers high-pressure water into the shell through a high-pressure water inlet pipe. The high-pressure water drives the high-pressure air pipe to rotate and enters the high-pressure air pipe through the through hole to be mixed and atomized with the high-pressure air pipe, and then is sprayed out through the nozzle. The high-pressure water and high-pressure gas are evenly mixed, the atomization effect is improved, and the atomization range is uniform and comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-3 The present invention provides a high-pressure atomizer for an iron mouth opening machine, comprising a shell 1 and a high-pressure air pipe 2. The shell 1 and the high-pressure air pipe 2 are both hollow cylindrical. A high-pressure water inlet pipe 3 is arranged on the side wall of the shell 1. The high-pressure air pipe 2 is rotatably arranged in the shell 1. The shell 1 and the high-pressure air pipe 2 are coaxially arranged. One end of the high-pressure air pipe 2 extends out of the shell 1 and is provided with a nozzle 4. The shell 1 is closed at this end. A sealing ring is provided at the closed end of the high-pressure air pipe 2 and the shell 1. A plurality of push plates 5 are provided on the circumference of the outer wall of the high-pressure air pipe 2 corresponding to the high-pressure water inlet pipe 3. The push plates 5 extend along the axis of the high-pressure air pipe 2. A plurality of through holes 2.1 are provided on the wall of the high-pressure air pipe 2 between the push plates 5. The high-pressure water inlet pipe 3 is inclined toward the push plate 5 but does not contact the push plate 5 to avoid interference with the rotation of the high-pressure air pipe 2.

[0016] In a specific embodiment of the present invention, an annular retaining groove 6 is provided on the inner wall of the housing 1. The annular retaining groove 6 is formed by two parallel annular plates. The annular plates are provided on the inner wall of the housing 1. An annular ridge 7 is provided on the outer wall of the high-pressure air pipe 2 to match the annular retaining groove 6. A steel ball 8 is provided at the bottom of the annular retaining groove 6. The annular ridge 7 is retained in the annular retaining groove 6 by the rolling motion of the steel ball 8. A plurality of annular retaining grooves 6 are provided according to the length of the housing 1, and the plurality of annular retaining grooves 6 are arranged in parallel. The nozzle 4 is tapered, with a larger inner portion and a smaller outer portion. The sidewall and outer end of the nozzle 4 are both provided with a spray hole 4.1. The nozzle 4 is located at one end of the housing 1 and is located at the other end. The nozzle 4 can be detachably connected to the high-pressure air pipe 2. The aperture of the through hole 2.1 is larger than the aperture of the spray hole 4.1. The high-pressure water inlet pipe 3 is inclined at an angle of 30-50 degrees. The water inlet of the high-pressure water inlet pipe 3 can accurately impact the push plate 5, driving the high-pressure water inlet pipe 3 to rotate.

[0017] When the present invention is working, high-pressure water enters the shell from the high-pressure water inlet pipe and impacts the push plate, pushing the high-pressure water inlet pipe to rotate. At the same time, high-pressure water enters the high-pressure air pipe through the through hole, and high-pressure gas is introduced into the end of the high-pressure air pipe away from the nozzle. The high-pressure gas and high-pressure water are mixed and atomized in the high-pressure air pipe and sprayed out through the nozzle hole of the nozzle.

[0018] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them.
