Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in fig. 1 to 3, the present invention comprises a housing 1, at least two filters 2 are installed on the radial wall of the housing 1, and the number of the filters 2 is preferably two or four, which is determined according to the capacity of the blower on site; the shell 1 is internally provided with the silencing unit 3, and the filter 2 is communicated with the silencing unit 3, so that the noise of air sucked by the blower can be greatly reduced, the running noise of the blower is reduced, and the requirement of industrial operation on the noise is met; the radial wall of the shell 1 is also provided with a rain cover 4 with an air suction inlet 41, and the rain cover 4 and the filter 2 are arranged in a one-to-one correspondence manner; the axial end of the housing 1 is provided with an air outlet duct 5. The utility model discloses a theory of operation does: air sucked by the filter is sucked from an air suction port 41 on the rain cover 4, enters the shell 1 through the filter 2 after being sucked, and is discharged into the blower through an air outlet pipeline 5 after passing through the silencing unit 3 in the shell 1.

In order to meet the requirements of filter disassembly and assembly and routine maintenance, the filter 2 is mounted on the shell 1 through the support 6, the two sides of the filter are fixed through the pressing plate 7, and the pressing plate 7 is connected and fixed with the shell 1 through the bolts, so that the filter 2 can be prevented from shaking in the filtering process, the stability of the filter can be guaranteed, and air sucked from the air suction port 41 can be smoothly filtered out of the filter 2.

In order to uniformly disperse and filter the air sucked by the air suction inlet 41 in the casing, the filters 2 are symmetrically distributed and positioned in the rain-proof cover 4, so that the sucked air can be filtered by the filters 2.

The filter 2 is a plate filter with a capacity of 6500m³The novel silencer comprises a filter plate 21, a filter plate upper baffle 22 and a filter plate lower baffle 23, wherein the filter plate 21 is installed between the filter plate upper baffle 22 and the filter plate lower baffle 23, the filter plate upper baffle 22 and the filter plate lower baffle 23 are respectively installed on a support 6, two ends of the filter plate 21 are respectively fixed through a pressing plate 7, and the filter plate 21 faces to the side wall of the silencing unit 3, so that air filtered by the filter plate 21 can smoothly enter the silencing unit 3, the noise of air sucked by an air blower can be greatly reduced, the running noise of the air blower is reduced, and the requirement of industrial operation on the noise is met.
