Abstract
The utility model belongs to a noise-reduction device of large equipment. According to the technical scheme, the noise-reduction device of the large equipment is composed of a steel bar net, a rock wool board, a perforated board, a steel carrying plate and an expansion screw, and is characterized in that the expansion screw is fixed on a wall surface, the steel bar net is fixed through the steel carrying plate, the perforated board is hung at the inner side of the steel bar net, and the rock wool board is arranged between the wall and the perforated board in an attaching mode. The noise-reduction device of the large equipment is simple in structure, is convenient to machine, saves a large amount of money, is small in occupied space, is convenient to maintain, is good in noise reduction effect, largely improves efficiency, and is ideal.
Description
Technical field
The utility model belongs to a kind of device of reduction noise of main equipment.
Background technology
Main equipment noise was very large in the past, traditional mode directly adopts noise damper noise-reducing, because coal mine ground induced draft fan noise is large, as adopt muffler assembly, not only claimed apparatus is many, and it is larger to take up space, and has the problem that increases flowing resistance, and price is expensive again, as adopt two complete equipment costs of use high.
Utility model content
The utility model, in order to solve the problem of above-mentioned prior art existence, provides the noise reduction device of the main equipment that a kind of maintenance cost is low.
The technical solution of the utility model is: a kind of noise reduction device of main equipment, the noise reduction device of this main equipment is by steel mesh reinforcement, rock cotton board, perforated plate, shell feed plate, setscrew composition, it is characterized in that, setscrew is fixed on metope, with the fixing steel mesh reinforcement of shell feed plate, perforated plate is mounted on steel mesh reinforcement inner side, and rock cotton board is mounted between wall and perforated plate.
The utility model is simple in structure, easy to process, and saves a large amount of funds, and floor space is little, easy to maintenance, and noise-reducing is effective.Having improved greatly efficiency, is the device of the reduction noise of more satisfactory main equipment.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is material arrangements schematic diagram of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
Detailed description of the invention
Shown in accompanying drawing 1-2, wherein: 1 setscrew, 2 shell feed plates, 3 steel mesh reinforcements, 4 perforated plates, 5 rock cotton board, 6 walls.
The noise reduction device of a kind of main equipment of the present utility model, the noise reduction device of this main equipment is by steel mesh reinforcement, rock cotton board, perforated plate, shell feed plate, setscrew composition, setscrew 1 is fixed on 6, wall, with the fixing steel mesh reinforcement 3 of shell feed plate 2, perforated plate 4 is mounted on steel mesh reinforcement inner side, and rock cotton board 5 is mounted between wall 6 and perforated plate 4.
In the time using the noise reduction device of main equipment, perforated plate absorbs a large amount of noises, passes to rock cotton board, and rock cotton board is due to softness, and the noise that perforated plate is absorbed is eliminated in the thick rock cotton board of 10cm, has so just played the effect of reduction noise.
