Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler used for a dust removal fan of a sintering furnace. Background Art

[0002] A muffler is a device that allows air to pass through and can reduce the noise of the air flow to a certain extent. It uses methods such as installing sound-absorbing materials in the exhaust pipe or suddenly expanding the cross-sectional area of ​​the device to quickly dissipate or reflect noise energy to limit noise propagation.

[0003] In the prior art, since the dust removal fan of the sintering furnace is accompanied by a lot of noise during operation, forming noise pollution and affecting people's lives, it is necessary to install a muffler at the air inlet or outlet of the fan to reduce the noise of the fan. However, when the natural wind or air flow in the workshop is introduced by the fan, the gas often contains a large amount of dust. After entering the muffler, it will enter the muffler hole, and then accumulate and block the muffler cotton, which greatly reduces the muffler effect. The existing technical solution is mainly to install a filter at the air inlet of the muffler to intercept the dust in the air flow so that the dust cannot enter the muffler.

[0004] However, due to the large air intake and high wind pressure of the fan, dust is easily adsorbed on the filter and is difficult to fall naturally. Therefore, the fan needs to be shut down every short period of time, and workers need to disassemble the filter for cleaning. Disassembly and installation of the filter is rather troublesome and greatly affects working hours and production progress. Utility Model Content
