Description

Technical Field

[0001] This utility model relates to the technical field of silencing devices, specifically a silencing device for a flotation machine lifting cone valve cylinder. Background Technology

[0002] Flotation machines are widely used in mining and mineral processing, and their lifting cone valve cylinders generate significant noise during operation. This noise not only damages the hearing of operators and affects the comfort of the working environment, but it can also interfere with the monitoring of equipment operation status, hindering safe and efficient production. Currently available noise reduction devices are not specifically designed to eliminate noise from the lifting cone valve cylinders of flotation machines, resulting in poor noise reduction effects and failing to meet actual production needs.

[0003] Therefore, those skilled in the art have provided a silencer for the cylinder of the lifting cone valve of a flotation machine to solve the problem mentioned above. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a silencer for the cylinder of the lifting cone valve in a flotation machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A silencer device for the lifting cone valve cylinder of a flotation machine includes:

[0007] The inner tube is open at the top and bottom, with the bottom fixedly installed at the center of the noise-generating area of ​​the flotation machine.

[0008] Multiple central bars are provided and combined to form a cylindrical shape, located at the bottom of the inner tube;

[0009] Side strips, multiple of which are combined to form a ring, surround the periphery of the multiple central strips and are located between the inner walls of the inner tube;

[0010] A circular plate is located above the center strip and the side strip, and the center of the circular plate bulges downward, with the bulging position corresponding to the top of the center strip;

[0011] A spring is located above the circular plate;

[0012] The pressure cap, connected to the top of the inner tube by threads, presses down on the spring and the circular plate, which in turn presses down on the center bar.

[0013] Preferably, the center strip and the side strips are arranged vertically and evenly, and the center strip and the side strips are provided with vertical reinforcing strips.

[0014] Preferably, there are four center strips and four side strips, with the center strips being quarter-cylindrical and the side strips being quarter-ring-shaped.

[0015] Preferably, an outer tube is sleeved around the inner tube, and the outer tube has evenly distributed round holes on its side, with a gap between the outer tube and the outer side wall of the inner tube.

[0016] Preferably, the top of the outer tube is fitted with a top cover, and the top cover is positioned higher than the circular hole on the side of the outer tube.

[0017] In summary, this utility model has the following beneficial technical effects:

[0018] 1. The top of the pressure cap and the inner tube are connected by threads, which press down on the spring and the circular plate. The protruding part in the middle of the circular plate corresponds to the top of the center bar, which better transmits the pressure of the spring to the center bar, ensuring that the center bar is in full contact with the center of the noise source, improving the noise reduction efficiency and improving the on-site environment.

[0019] 2. By adjusting the threaded connection between the gland and the inner tube, the compression of the spring can be easily adjusted, thereby adjusting the compression state of the center bar and the side bar to meet the noise reduction requirements under different working conditions.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] A silencer for the cylinder of the lifting cone valve of a flotation machine, as described in the reference. Figure 1-3 ,include:

[0027] The inner tube 1 has an open top and bottom. The bottom is fixedly installed at the center of the noise generation point of the flotation machine, serving as the basic support structure for the entire silencing device and providing installation space for other components.

[0028] The center bar 2, which consists of multiple bars arranged to form a cylindrical shape, is located at the bottom of the inner tube 1 and comes into contact with the noise source. It plays a crucial role in noise absorption and buffering during the noise reduction process.

[0029] Side strips 3, which are provided in multiples and combined to form a ring, surround multiple center strips 2 and are located between the inner walls of the inner tube 1. They work together with the center strips 2 to further enhance the blocking and absorption of noise.

[0030] The circular plate 5 is located above the center strip 2 and the side strip 3, and the center of the circular plate 5 protrudes downward, with the protrusion corresponding to the top of the center strip 2. Through its special shape design, the pressure of the spring 6 is better transmitted to the center strip 2, ensuring that the center strip 2 is in full contact with the center of the noise source, improving the noise reduction efficiency and improving the on-site environment.

[0031] Spring 6, located above circular plate 5, uses its own elastic deformation to provide continuous pressure to circular plate 5, ensuring the structural stability of the silencing device and the continuity of the silencing effect.

[0032] The pressure cap 7 is connected to the top of the inner tube 1 by a thread, which presses down on the spring 6 and the circular plate 5. The circular plate 5 presses down on the center bar 2. By adjusting the degree of thread connection between the pressure cap 7 and the inner tube 1, the compression amount of the spring 6 can be easily adjusted, thereby adjusting the compression state of the center bar 2 and the side bar 3 to adapt to the noise reduction requirements under different working conditions.

[0033] Both the center strip 2 and the side strips 3 are arranged vertically and evenly, and each strip has a vertical reinforcing strip 4 inside. This ensures that the entire silencing device is subjected to more even force in the vertical direction, preventing deformation or damage to components due to uneven force. The reinforcing strip 4 further enhances the strength and rigidity of the center strip 2 and the side strips 3, allowing them to maintain good shape and structural integrity when subjected to the pressure of the spring 6 and noise impact, extending the service life of the device and ensuring the continuous and stable operation of the silencing function.

[0034] There are four center bars 2 and four side bars 3, with the center bars 2 being a quarter-cylinder shape and the side bars 3 being a quarter-ring shape. The entire silencing device has a high degree of symmetry in the circumferential direction. This symmetrical structure allows the device to be subjected to noise impact and spring 6 pressure evenly, effectively avoiding deformation or damage caused by uneven stress, and improving the structural stability and durability of the device. At the same time, the regular shape and number facilitate precise matching and installation between components, reducing potential problems caused by installation errors.

[0035] An outer tube 8 is fitted around the inner tube 1, with a gap between the outer tube 8 and the outer wall of the inner tube 1. This gap forms a resonant cavity. When noise propagates through the inner tube 1 into the gap, the sound waves are reflected and interfered with within this space, resulting in the dissipation of some energy. The outer tube 8 has evenly spaced circular holes on its side. These holes allow some noise to escape to the outside of the outer tube 8. During this escape, the circular holes disperse the airflow, reducing local airflow velocity and further decreasing airflow noise. The friction between the sound waves and the edges of the circular holes further dissipates the sound energy. This multi-stage noise reduction structure significantly improves the overall noise absorption capacity of the device.

[0036] The top of the outer tube 8 is fitted with a top cover 9. The top cover 9 is positioned higher than the round hole on the side of the outer tube 8. The design of the top cover 9 forms a closed structure at the top of the outer tube 8, which can prevent dust, debris and other objects from falling into the interior from the top, and also facilitates the maintenance and replacement of the internal structure of the outer tube 8 by the staff.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
