[0040] Example:
[0041] See also Figure 1-4 A cold air silencer with a filter comprises a sand suction machine body 1, the tail gas end flange of the sand suction machine body 1 is connected with a connecting pipe 2, the top flange of the connecting pipe 2 is connected with a purification box 3, the top flange of the purification box 3 is connected with an exhaust port 15, the internal chamber of the purification box 3 is sealed and connected with a filter box 4, a plurality of exhaust channels 5 are connected through the filter box 4, a plurality of baffles 6 are arranged on the outer periphery of the exhaust channel 5, filter cotton 7 is filled between the inner wall of the filter box 4 and the exhaust channel 5, a filter box 2 8 is fixedly connected to the top of the filter box 4, a multi-layer activated carbon filter plate 9 is arranged inside the filter box 2 8, a return chamber 10 is arranged in the box wall of the filter box 2 8, the return chamber 10 is communicated with the filter box 4, the inner cavity of the filter box 2 8 is communicated with the top of the exhaust channel 5, and a noise reduction mechanism 11 is arranged inside the exhaust port 15.
[0042] See also Figure 3 The bottom end of the exhaust channel 5 is connected with the lower chamber of the purification box 3. An air inlet is opened at the bottom of the exhaust channel 5, and the air inlet is connected with the inside of the filter box 4. When in use, the air inlet can be set to divert and slow down the incoming gas, thereby consuming part of its kinetic energy and achieving the effect of noise reduction.
[0043] See also Figure 3 A plurality of air outlet holes 12 and 13 are provided on the top of the filter box 8 , and the air outlet holes 13 are communicated with the return cavity 10 .
[0044] See also Figure 4 The noise reduction mechanism 11 includes a wind cover 111 fixed on the inner wall of the exhaust port 15, a light rod 112 fixedly connected to the inside of the wind cover 111 by two brackets 115, and a noise reduction baffle 113 is provided on the outer peripheral sliding sleeve of the light rod 112. The top and bottom of the noise reduction baffle 113 are provided with buffer springs 114. When in use, the buffer spring 114 cooperates with the noise reduction baffle 113 and utilizes the elastic force generated by the deformation of the buffer spring 114 to decelerate the airflow and consume the excess kinetic energy again, so that the noise reduction effect is further improved.
[0045] See also Figure 4The buffer spring 114 is sleeved on the outer periphery of the light rod 112, and the two ends are fixedly connected to the noise reduction baffle 113 and the corresponding bracket 115 respectively.
[0046] See also Figure 4 An inner groove is provided at the bottom of the noise reduction partition 113.
[0047] See also Figure 2 A mounting hole is provided on one side of the purification box 3, and a side cover 14 is installed on the outer opening of the mounting hole.

At the same time, during the flow of the gas, the diversion of the exhaust channel 5 and the action of multiple baffles 6 can slow down the airflow during the circulation process, and then consume the excess kinetic energy, so as to achieve the purpose of silencing. When the gas passes through the exhaust port 15, the gas impacts the noise reduction baffle 113. Under the action of the deformation of the buffer spring 114, the airflow can be slowed down and the excess kinetic energy is consumed again, so that the noise reduction effect is further improved. The overall structure cooperates with each other to effectively avoid the impact on the surrounding environment.
