[0002] The pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as a power source. It can pump out all kinds of corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids. However, the existing pneumatic diaphragm pumps produce a lot of noise during operation. If there is no silencer structure, long-term exposure to noise will affect the hearing of the staff, or even cause deafness. However, the existing muffler has a poor noise reduction effect, is inconvenient to install, and has poor corrosion resistance. When the air contains moisture, the moisture is liquefied under high pressure, which can easily cause moisture to spray out of the muffler, causing the pneumatic diaphragm pump to work abnormally.

[0003] During the use of the pneumatic diaphragm pump, a noise reduction and anti-condensation muffler for the pneumatic diaphragm pump is needed. After searching, the Chinese patent CN208950845U in the prior art discloses a noise reduction and anti-condensation muffler for a mining pneumatic diaphragm pump, including a muffler body, an inclined muffler cavity fixedly connected to the other side of the mounting base, a muffler structure cavity fixedly connected to the other side of the inclined muffler cavity, and a first muffler structure channel fixedly opened at the top and bottom of the muffler structure cavity. The utility model utilizes the inclined muffler cavity and the muffler structure cavity, the muffler cotton in the inclined muffler cavity and the muffler structure cavity, and the first muffler structure channel to effectively reduce noise.

[0004] However, the utility model noise reduction and anti-condensation muffler for mining pneumatic diaphragm pump uses self-locking screws to thread the threaded holes on the mounting base and the air outlet on the pneumatic diaphragm pump. When replacing the muffler according to different needs, the disassembly and assembly steps are cumbersome and cannot meet the use requirements. Therefore, a noise reduction and anti-condensation muffler for mining pneumatic diaphragm pump is proposed to solve the above-mentioned problems. Utility Model Content
