[0002] At present, the devices and equipment used for vibration in China are mainly divided into two categories, the first is electric vibration and the second is pneumatic vibration. Electric vibration refers to the vibration that consumes electric energy and drives the corresponding equipment to rotate through the rotation of the motor; pneumatic vibration refers to the vibration of the equipment through the reciprocating motion of the corresponding piston and other structures by consuming compressed air. Both have their own advantages and disadvantages, and are widely used in various industries.

The temperature in this working environment is greater than 300°C, the space volume is at least 100m³, and there is a large amount of dust in the space. In this environment, the device is arranged in a large space. The electric vibration motor is resistant to temperature differences, the pneumatic vibration piston is easily stuck due to dust, and the air hose used in pneumatic vibration is not heat-resistant enough. The vibration equipment is arranged outside the large space to vibrate the equipment in the space.

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] according to Figure 1 , Figure 2 and Figure 3 As shown, a pneumatic rapping device suitable for use in a high-temperature, dusty, large space environment comprises an air delivery component and an impact wheel 3, wherein the impact wheel 3 is rotatably arranged on a wheel axle support 8, a plurality of moving blades 5 are equidistantly arranged circumferentially on the impact wheel 3, and a rapping piece 1 for rapping the equipment is rotatably arranged on the impact wheel 3, the rapping piece 1 is rotatably arranged so that the rapping piece 1 can bypass the equipment after hitting it, thereby achieving continuous rapping, the compressed air output by the air delivery component is directly facing the moving blades 5, thereby blowing the moving blades 5 to drive the impact wheel 3 to rotate, and the rapping piece 1 is thrown out under the action of centrifugal force, thereby continuously rapping the equipment.

[0024] By arranging the present design inside a large space, close to the equipment to be vibrated, the present design drives the impact wheel 3 to rotate by blowing the moving blades 5 with compressed air to make the vibrating piece 1 vibrate. This design can be used for a long time under harsh conditions such as high temperature and dust.

[0025] A rotating shaft 4 is radially arranged at the center of the impact wheel 3 , and the rotating shaft 4 is rotatably arranged on a wheel shaft support 8 .

[0026] The radial cross section of the moving blade 5 is preferably V-shaped, semicircular or U-shaped. This structure is beneficial for the moving blade 5 to absorb the compressed air output by the air delivery component, thereby driving the impact wheel 3 to rotate through the moving blade 5.

[0027] One end of the rapping piece 1 is rotatably connected to the impact wheel 3 via a pin shaft. When the impact wheel 3 rotates, the free end of the rapping piece 1 is thrown outward under the action of centrifugal force to vibrate the equipment. After hitting the equipment, the rapping piece 1 rotates around the pin shaft to bypass the equipment, thereby achieving continuous vibration.

[0028] In order to increase the frequency and effect of rapping the equipment, a plurality of rapping pieces 1 may be provided.

[0029] The air delivery component includes an air distributor 7, a main pipe 9 and a branch pipe 6. The air distributor 7 is connected to an air supply mechanism through the main pipe 9. The air supply mechanism is located outside a large, high-temperature, dusty space. The outlet end of the branch pipe 6 connected to the air distributor 7 is aligned with the moving blades 5 so as to blow the moving blades 5 so as to drive the impact wheel 3 to rotate through the output compressed air. In a further implementation method, a plurality of branch pipes 6 may be used, and the outlet ends of the branch pipes 6 are all aligned with the moving blades 5 so as to blow the moving blades 5 so as to drive the impact wheel 3 to rotate through the output compressed air. In a further embodiment, a valve 11 is connected in series on the main pipe 9 so as to achieve automatic control.

[0030] according to Figure 4 As shown, the outlet end of the branch pipe 6 is connected to the air collecting hood 2, and the side of the air collecting hood 2 is provided with an open end 10 for the moving blades 5 to enter and exit in a rotating state. The moving blades 5 enter through the open end 10 on one side and fly out from the open end 10 on the other side. The compressed air blown out of the branch pipe 6 can completely act on the moving blades 5. The air collecting hood 2 can improve the utilization rate of the compressed air. The air collecting hood 2 can prevent the ejected compressed air from spreading rapidly to the surroundings, so that the blown compressed air can act on the moving blades 5 as much as possible, which greatly improves the work efficiency. During the rotation process, the minimum distance between the moving blades 5 and the inner wall of the air collecting hood 2 in all directions is controlled to be about 1 mm.

[0031] The vibration devices are all made of high temperature resistant materials, and the high temperature resistant materials are preferably stainless steel or alloy steel to ensure that the devices can work normally under high temperatures.

[0032] Working principle: the compressed air generated by the air supply mechanism enters the air distributor 7 through the main pipe 9, the compressed air entering the air distributor 7 is diverted into the branch pipe 6, and the compressed air is ejected from the outlet end of the branch pipe 6 to blow toward the moving blades 5. Under the action of the compressed air, the impact wheel 3 is driven to rotate. During the rotation, the rapping piece 1 is thrown outward under the action of centrifugal motion, and the rapping piece 1 vibrates the vibrated equipment.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
