Technical Field

[0001] This utility model relates to the field of horizontal silencer technology, specifically a horizontal silencer. Background Technology

[0002] The primary and secondary compressors of the air compressor are connected by a buffer. Due to the high pressure and fast flow rate of the compressed air, noise is generated in the buffer. This noise is high in decibels and sharp, exceeding the noise requirements of the workshop and affecting its use.

[0003] In the prior art, utility model patent with announcement number CN206655795U provides a buffer silencer, especially a horizontal buffer silencer, including a primary silencer, a secondary silencer, a wall-mounted silencing device, and a speed-up pipe; the primary silencer has an air inlet hole on its wall, an air inlet flange above the air inlet hole, and the air inlet flange is connected to the air inlet hole through an air inlet pipe; one end of the primary silencer has a closed cover, and the other end is coaxially welded to one end of the secondary silencer; the other end of the secondary silencer has a flat cover, an air outlet hole on the flat cover, and an air outlet flange on one side of the flat cover, which is connected to the air outlet hole through an air outlet pipe; the wall-mounted silencing device is installed on the inner walls of the primary silencer and the secondary silencer respectively.

[0021] Please see Figure 1-3 A horizontal silencer includes a silencer cylinder 1, an air inlet pipe 2, an air outlet pipe 3, and a drain pipe 4. The bottom of the drain pipe 4 is inserted into and connected to a collection cylinder 5. The collection cylinder 5 is equipped with an installation mechanism 6 for fixing the collection cylinder 5 to the bottom of the silencer cylinder 1. The installation mechanism 6 includes a threaded seat 61 for fixing the bottom of the silencer cylinder 1. The threaded seat 61 is threaded to the outer wall of the collection cylinder 5 for threading the collection cylinder 5 onto the bottom of the drain pipe 4. The bottom of the threaded seat 61 has a first ring 62, and the outer wall of the collection cylinder 5 has a second ring 63. A cable tie 64 for connecting ring 62 and ring 63 passes through the ring 62 and ring 63 respectively. The collecting cylinder 5 is below the muffler 1. The collecting cylinder 5 is equipped with a removable filter element. The collecting cylinder 5 has a cylindrical structure. The side wall of the collecting cylinder 5 near the top is provided with threads. The top of the threaded seat 61 is fixedly connected to the bottom of the muffler 1. The threaded seat 61 has a ring structure. The threads of the threaded seat 61 are provided on the inner circular surface. Both ring 62 and ring 63 are provided with at least two sets. The cable tie 64 is a stainless steel strip. The length of the cable tie 64 is greater than the circumference of the collecting cylinder 5.

[0022] The collection cylinder 5 collects the mixed liquid discharged from the drain pipe 4. Remove the cable tie 64, which separates from the ring body 62 and the ring body 63. Then rotate the collection cylinder 5, which rotates and separates from the threaded seat 61. Remove the collection cylinder 5 and replace the internal filter element. Then install the collection cylinder 5 (or replace the collection cylinder 5 directly) so that it can collect the mixed liquid discharged from the drain pipe 4 and prevent the collection cylinder 5 from falling off due to vibration.

[0023] The silencer 1 is equipped with a silencer mechanism 7, which includes a steel plate 71 on the inner wall of the silencer 1. A metal wire mesh 72 is fixed on the inner circular surface of the steel plate 71, and a steel wire ball 73 is provided on the inner circular surface of the metal wire mesh 72. The steel plate 71 is a hollow cylindrical structure and is a perforated steel plate.

[0024] In use, compressed air enters the silencer cylinder 1 of the horizontal buffer silencer through the air inlet pipe 2. Utilizing the noise reduction properties of porous materials, the sound-absorbing material is fixed on the inner wall of the airflow channel. When sound waves enter the silencer, due to the action of friction and viscous resistance, some of the sound energy is converted into other forms of energy, thus achieving the effect of noise reduction.

[0025] Working principle: The collection cylinder 5 of this utility model collects the mixed liquid discharged from the sewage pipe 4. The cable tie 64 is removed and separated from the ring body 62 and the ring body 63. Then, the collection cylinder 5 is rotated and the collection cylinder 5 is separated from the threaded seat 61. The collection cylinder 5 is removed and the internal filter element is replaced. Then the collection cylinder 5 is installed to collect the mixed liquid discharged from the sewage pipe 4 and to prevent the collection cylinder 5 from falling off due to vibration. When in use, compressed air enters the silencer cylinder 1 of the horizontal buffer silencer through the air inlet pipe 2. The sound-absorbing material is fixed on the inner wall of the airflow channel by the performance of the porous material in reducing noise. When the sound wave enters the silencer, due to the action of friction and viscous resistance, part of the sound energy is converted into other forms of energy, which plays a role in noise reduction.
