Technical Field

[0001] The utility model relates to the technical field of large fans, in particular to a fan silencer with stable connection. Background Technique

[0002] Large fans usually refer to fan devices with large sizes and high output powers. They play an important role in the industrial and energy fields. During the use of large industrial fans, fan silencers are often required.

[0003] After retrieval, the patent number is CN204755411U, and the name is a silencer for a fan. It has good silencing effect, simple structure, easy installation, and low manufacturing cost. This silencer for a fan includes an air inlet, an outer cylinder, and an air outlet. The air inlet is connected to the fan. Through research and analysis, it is found that although it has the advantage of being easy to install, to a certain extent, it also has the following disadvantages.

[0004] For example, during the use of the above-mentioned fan silencer, its silencing distance usually cannot be adjusted, which may affect the connection stability of its main body to a certain extent. At the same time, the noise is filtered by the method of filtering and silencing through a silencing filter screen, resulting in poor silencing effect of its main body. To solve the above technical problems, we have designed a fan silencer with stable connection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fan silencer with stable connection, which has the advantages of stable connection and good silencing effect, and solves the problems of relatively general connection stability and poor silencing effect.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fan silencer with stable connection, including a silencer main body. A silencer expansion pipe is penetrated through the left side of the silencer main body. The silencer expansion pipe includes a sound absorption layer. A corrosion-resistant layer is arranged on the outer side of the sound absorption layer. A rigid buffer layer is arranged on the outer side of the corrosion-resistant layer. A silencing mechanism is arranged at the bottom on the left side of the silencer expansion pipe. The silencing mechanism includes a damping sliding rod. Support mechanisms are arranged on the front and rear sides of the silencer expansion pipe. The support mechanism includes a fixing plate. One side of the fixing plate close to the silencer expansion pipe is welded to the silencer expansion pipe.

[0007] Preferably, a guiding moving groove is opened at the bottom of the fixing plate. A guiding connecting block is arranged in the inner cavity of the guiding moving groove. An arc-shaped supporting plate is welded to the bottom of the guiding connecting block.

[0008] Preferably, a groove is formed in the bottom of the silencer body. The front and rear sides of the damping slide bar are welded to the inner wall of the groove. A damping sleeve is sleeved on the surface of the damping slide bar in a damping manner. A silencing filter screen is welded to the left side of the damping sleeve. A connecting seat is welded to the left side of the silencing filter screen. Placing rods are welded to the front and rear sides of the connecting seat. Sliding holes for the placing rods to cooperate with are formed in the front and rear sides of the silencer extension pipe.

[0009] Preferably, holding handles are welded to the front and rear sides of the silencer extension pipe. Anti-slip patterns are formed on the surface of the holding handles.

[0010] Preferably, the sound-absorbing layer is specifically made of asbestos fiber material, the corrosion-resistant layer is specifically made of ABS material, and the rigid buffer layer is specifically made of aluminum alloy material.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1.

Detailed implementation manner

[0019] Please refer to Figures 1 - 4 , a blower silencer with stable connection, including a silencer body 1. A silencer extension pipe 2 penetrates through the left side of the silencer body 1. The silencer extension pipe 2 includes a sound-absorbing layer 15. The outside of the sound-absorbing layer 15 is provided with a corrosion-resistant layer 16. The outside of the corrosion-resistant layer 16 is provided with a rigid buffer layer 17. A silencing mechanism 13 is arranged at the bottom of the left side of the silencer extension pipe 2. The silencing mechanism 13 includes a damping slide bar 8. Support mechanisms 14 are arranged on both the front and rear sides of the silencer extension pipe 2. The support mechanism 14 includes a fixing plate 12. One side of the fixing plate 12 close to the silencer extension pipe 2 is welded to the silencer extension pipe 2.

[0020] Please refer to Figure 2 , a guiding moving groove 11 is opened at the bottom of the fixing plate 12. By providing the guiding moving groove 11, the guiding connection block 18 can be guided during the moving process, thereby improving the moving stability of its main body. A guiding connection block 18 is arranged in the inner cavity of the guiding moving groove 11. An arc-shaped supporting plate 10 is welded to the bottom of the guiding connection block 18. By providing the arc-shaped supporting plate 10, the silencing filter 5 can be balanced and supported, facilitating the installation stability after the position adjustment of the placing rod 6.

[0021] Please refer to Figure 2 , a groove 9 is opened at the bottom of the silencer body 1. Both the front and rear sides of the damping slide bar 8 are welded to the inner wall of the groove 9. A damping sleeve 7 is sleeved on the surface of the damping slide bar 8 in a damping manner. A silencing filter 5 is welded to the left side of the damping sleeve 7. A connecting seat 4 is welded to the left side of the silencing filter 5. Placing rods 6 are welded to both the front and rear sides of the connecting seat 4. Sliding holes for the placing rods 6 to cooperate with are opened on both the front and rear sides of the silencer extension pipe 2.

[0022] Please refer to Figure 2 , holding handles 3 are welded to both the front and rear sides of the silencer extension pipe 2. Anti-slip patterns are opened on the surface of the holding handles 3. By providing the anti-slip patterns, the friction between the holding handles 3 and the user's hands can be increased, thereby facilitating the user to hold the holding handles 3.

[0023] Please refer to Figure 4 , the sound-absorbing layer 15 is specifically made of asbestos fiber material, the corrosion-resistant layer 16 is specifically made of ABS material, and the rigid buffer layer 17 is specifically made of aluminum alloy material.

[0024] When in use, when the user needs to extend the sound insulation distance of the main body, the user can manually pull the holding handle 3 to drive the silencer expansion pipe 2 to move, so as to complete the distance adjustment. By extending the sound insulation distance, the sound insulation effect of the main body can be improved. When it is necessary to filter and silence, the user can manually pull the silencer filter screen 5 to drive it to slide in the inner cavity of the sliding hole. After moving to a suitable position, manually push the arc-shaped supporting plates 10 on the front and back sides to make it move to a suitable position to balance and support the silencer filter screen 5. By filtering and silencing the blowing air, the sound insulation effect of the main body can be improved. By setting the rigid buffer layer 17, during the use process, the sound insulation effect of the silencer expansion pipe 2 can be improved through rigid shock absorption. By setting the corrosion-resistant layer 16, the erosion of corrosive gases and liquids generated during the operation of the fan can be effectively resisted, and the service life of the fan silencer can be improved. By setting the sound-absorbing layer 15, during the filtering process, the noise generated inside can be directly absorbed, thus achieving a better sound insulation effect.

[0025] In summary: The fan silencer with stable connection solves the problems of relatively general connection stability and poor sound insulation effect through the combined use of the damping sleeve 7, damping slide rod 8, groove 9, arc-shaped supporting plate 10, guiding movement groove 11 and fixing plate 12.
