Description

Technical Field

[0001] The utility model belongs to the field of boiler equipment and relates to an air shock wave sootblower device, in particular to a 360-degree rotating nozzle device using aerodynamics. Background Art

[0002] In the prior art, air shock wave sootblowing is one of the commonly used sootblowing equipment for boiler sootblowing. It mainly uses high-pressure compressed air to release a huge shock wave under the action of a piston to clean the accumulated dust in the economizer, superheater, and air preheater of the boiler. At present, the prior art has a single sootblowing structure for air shock wave sootblower, a small sootblowing area, a large number of installations, high equipment cost, and low working efficiency of the sootblower. The main reason is that the nozzle of the equipment is fixed and cannot be freely selected and rotated, resulting in a small sootblowing area, and there are dead corners on the heating surface of the boiler that cannot be cleaned. At the same time, the equipment has a limited working distance, and a relatively large number of units need to be installed.

[0003] Based on the above technical problems, it is urgent to design a 360-degree rotating nozzle device using aerodynamics. Utility Model Content

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a 360-degree rotating nozzle device using aerodynamics to achieve a compact structure, stable and reliable, and improved cleaning efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A 360-degree rotating nozzle device using aerodynamics comprises a main pipe and a nozzle, wherein one end of the main pipe is provided with a connecting flange, and the other end is provided with an upper rotator; the bottom end of the upper rotator is sealed and rotatably connected to a lower rotator, the bottom of the lower rotator is provided with a nozzle, and a plurality of blowing ports are provided on the nozzle;

[0007] As a limitation of the present utility model, a plurality of rotating beads are sandwiched between the upper rotator and the lower rotator;

[0008] As a further limitation of the present invention, a bead groove is provided at the bottom of the upper rotator corresponding to the bead, and the depth of the bead groove is greater than the radius of the bead and less than the diameter of the bead;

[0009] As a further limitation of the present invention, a rotation groove is provided at the top of the lower rotator corresponding to the rotating ball, and the depth of the rotation groove does not exceed the radius of the rotating ball;

[0010] The upper rotator is provided with a rotating bead groove for accommodating the rotating bead to fix the position of the rotating bead; the lower rotator is provided with a rotating groove to facilitate the rotation of the rotating bead and also to make the upper rotator and the lower rotator contact more closely;

[0011] As another limitation of the present utility model, an oil delivery hole is provided on the upper rotator;

[0012] The oil delivery hole is set to facilitate the addition of lubricating oil between the upper and lower rotators, which is convenient for the maintenance of the upper and lower rotators and reduces the difficulty of maintenance of the upper and lower rotators.

[0013] As a third limitation of the present invention, the nozzle is provided with at least three blowing ports, namely a first blowing port, a second blowing port and a third blowing port;

[0014] As a further limitation of the present invention, the angle between the first blowing port and the horizontal direction is 45°;

[0015] As a further limitation of the present invention, the second blowing port is perpendicular to the horizontal direction;

[0016] As a further limitation of the present invention, the angle between the third blowing port and the horizontal direction is 75°.

[0017] By having multiple nozzles with different angles to the horizontal direction, high-pressure gas can be blown from the nozzles while providing rotational power to the nozzle, allowing the nozzle to rotate 360°.

[0018] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0019] The utility model relates to a 360-degree rotating nozzle device using aerodynamics, which has a simple structure and a large blowing range, thereby improving the efficiency of the soot blower. Meanwhile, the utility model has a compact structure, is stable and reliable, and is easy to promote and use.
