A damping, muffling and air compensation device for an orifice plate comprises an adjustment valve for adjusting air compensation capacity, a micropore muffler and an orifice-plate damper. The micropore muffler comprises a muffling tube and a housing sleeved outside the muffler, two ends of the housing are open, and the left end of the housing is connected with the adjustment valve. Two ends of the muffling tube are open and fixedly connected with the housing, a first chamber is formed between the housing and the muffling tube, and the left and right ends of the first chamber are closed. The orifice-plate damper is arranged in the muffling tube, and comprises a plurality of orifice plates arranged in parallel at intervals, and a second chamber is formed between the adjacent two orifice plates; the wall of the muffling tube is provided with a first air hole allowing the airflow on the right side of the orifice-plate damper to enter the first chamber, and a second air hole allowing the airflow in the first chamber to enter in the second chamber. The damping, muffling and air compensation device has the effective function of damping and air compensation, can make sure pressure of the manifold / branch pipe constant. The damping, muffling and air compensation device integrates the air compensation and the noise reduction function, reduces the external dimension of the product and saves the installation space.
Description
technical field [0001] The invention relates to an air replenishing device with the functions of replenishing air and noise reduction, which is used for replenishing air for the main / branch pipes of wind power wire feeding and cigarette centralized process wind dust removal systems. Background technique [0002] In the current cigarette industry, wind wire feeding and centralized process wind dust removal systems are widely used because of their significant advantages such as noise reduction, convenient maintenance, environmental protection and energy saving. A system usually includes 4-6 cigarette making machines. The process wind branch pipe of each cigarette machine is connected to the process wind main pipe in parallel. The process wind related parameters are designed according to the number of cigarette machines incorporated, and all cigarette machines in the system work at the same time. Determine the air volume of the system fan and select the model and specification ...
