Abstract
The utility model discloses a noise reducing reforming device for a fan in a spinning workshop and relates to a noise reducing device for the fan. A tank body is cuboid and is of a double-layer structure; a tank body casing is formed by welding steel plates; a cellular foam board is arranged on an inner layer; noise-absorbing holes with different sizes are formed in the cellular foam board; damping legs are arranged at the bottom end of the tank body; the fan is arranged in the tank body and is connected with a dust absorbing pipeline; and a plurality of horn-shaped dust absorbing ports are formed in the dust absorbing pipeline. After the noise reducing reforming device is subjected to trial, a more ideal noise reducing effect is obtained, noises can be reduced by about 10-20 decibels and the labor protecting standard for staff specified by 'Environmental Protection Law of the PRC' can be met. The noise reducing reforming device disclosed by the utility model has the advantages of simple structure, convenience in mounting and use and low manufacturing cost; and in addition, the noise of the fan can be effectively reduced while dust is eliminated and the effects of absorbing noise and reducing noise are achieved.
Description
Technical field
The utility model relates to the blower fan noise-reducing device for modifying of a kind of denoising device of blower fan, particularly a kind of spinning workshop.
Background technique
Since China reform and opening-up, national economy obtains rapid growth, has become the main flow of the present industrial development of China with " scientific and technical innovation, autonomous innovation ", and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Blower fan is the ventilation device that is widely used in the occasions such as factory, mine, boats and ships, building.Blower fan is when high speed operation, and air-flow causes the pollution of environment through producing larger noise in the process of blower fan, also has a strong impact on the healthy of worker and surrounding population.According to China the Law on Environmental Protection of the People's Republic of China regulation, industrial enterprise's noise standard must not be above 90 decibels.And the fan noise of spinning workshop is usually up to the 100-120 decibel, even larger.Blower fan in the existing ventilation equipment generally suppresses the blower fan rotational noise by the optimal design to blower fan pattern and blade shape, but the optimal design that relies on merely blower fan self still is difficult to the usage requirement that reaches desirable.In order to address this problem, R﹠D institution and science and technology in enterprise personnel are in constantly research, exploration, utilize modern science and technology, blower fan to existing spinning workshop carries out the noise-reducing transformation, although obtained technically some progress, in practice, still existed the technical barrier that not yet overcomes.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of blower fan noise-reducing device for modifying of spinning workshop is provided, and increases the noise reduction casing by the outside at blower fan again, thereby has further reduced noise pollution.This apparatus structure is simple, and is easy to install, and fabricating cost is low, and can effectively reduce fan noise, realizes the sqouynd absorption lowering noise effect.
The technological scheme that its technical problem that solves the utility model adopts is: contain casing, honeycomb foam plate, dust-sucking hole, dust sucting pipeline, vibration damping pin, blower fan, it is rectangular-shaped that casing is, and be double layer construction, cabinet shell adopts Plate Welding to form, internal layer is provided with the honeycomb foam plate, be provided with the uneven sound-absorption hole of size at the honeycomb foam plate, the casing bottom is provided with the vibration damping pin, in casing, be provided with blower fan, blower fan is connected with dust sucting pipeline, dust sucting pipeline is provided with a plurality of trumpet-shaped dust-sucking holes, has formed a kind of blower fan noise-reducing device for modifying of spinning workshop.
The know-why that the utility model adopts is: blower fan is when work, the intake grill of blower fan is connected with the dust sucting pipeline in spinning mill workshop, dust sucting pipeline is provided with a plurality of dust-sucking holes, is suspended in the little suede of airborne cotton yarn and dust in the Spinning process and sucks collection through dust-sucking hole.Blower fan is fixed in the casing, and cabinet wall is provided with the honeycomb foam plate, and the honeycomb foam plate is provided with the uneven sound-absorption hole of size, and blower fan is when work, and air-flow is absorbed by sound-absorption hole by the noise that produces in the blower fan process is very most of.Also be provided with the vibration damping pin in the casing lower end, prevented that blower fan from because of the secondary noise that Vibration propagation produces, further reaching the noise reduction of blower fan.
The utility model beneficial effect is: this device is through on probation, and noise reduction is more satisfactory, can make about noise decline 10-20 decibel, can satisfy the Law on Environmental Protection of the People's Republic of China's regulation to worker's labour protectig standard.This model utility is simple in structure, and is easy to install, and fabricating cost is low, and when eliminating dust, can effectively reduce fan noise, realizes the sqouynd absorption lowering noise effect.

The below further describes the utility model in conjunction with the accompanying drawings and embodiments:
It is a kind of blower fan noise-reducing device for modifying structural representation of spinning workshop among the figure.
In the drawings: 1. casing, 2. honeycomb foam plate, 3. dust-sucking hole, 4. dust sucting pipeline, 5. vibration damping pin, 6. blower fan.
Embodiment
In the drawings, casing 1 is rectangular-shaped, and be double layer construction, the shell of casing 1 adopts Plate Welding to form, and internal layer is provided with honeycomb foam plate 2, and honeycomb foam plate 2 is provided with the uneven sound-absorption hole of size, be provided with vibration damping pin 5 in the bottom of casing 1, be provided with blower fan 6 in the casing 1, blower fan 6 is connected with dust sucting pipeline 4, and dust sucting pipeline 4 is provided with a plurality of trumpet-shaped dust-sucking holes 3.
Blower fan 6 is when work, and the intake grill of blower fan 6 is connected with the dust sucting pipeline 4 in spinning mill workshop, and dust sucting pipeline 4 is provided with a plurality of dust-sucking holes 3, in Spinning process, is suspended in the little suede of airborne cotton yarn and dust and sucks collection through dust-sucking hole 3.Blower fan 6 is fixed in the casing 1, and casing 1 inwall is provided with honeycomb foam plate 2, the uneven sound-absorption hole of tool size on the honeycomb foam plate 2, and blower fan 6 is when work, and air-flow is absorbed by sound-absorption hole by the noise that produces in blower fan 6 processes is very most of.Also be provided with vibration damping pin 5 in casing 1 lower end, prevented that blower fan 6 from because of the secondary noise that Vibration propagation produces, further reaching the noise reduction of blower fan 6.The utility model is through on probation, and noise reduction is more satisfactory, can make about noise decline 10-20 decibel.
