Description
Technical Field
The utility model relates to an environmental protection engineering technical field specifically is a dust absorption fan noise insulation.
Background
Dust exhausting fan equipment is more common in industrial production, and power is big moreover, and the noise value that produces is also relatively great. The noise value generated by the fan equipment during operation is over 100 decibels, and the noise value seriously exceeds the environmental noise emission standard of industrial plants. In order to ensure physical and psychological health of workers, the fan needs to be subjected to sound insulation and noise reduction treatment so as to ensure that the requirement of environmental protection is met.
For small-scale and low-profit industrial enterprises, a simple partition is usually used to separate blower equipment from personnel, or workers can directly wear earplugs. But the practical effect is very limited, and meanwhile, the normal work communication in a workshop is also influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve prior art's problem, provide a dust absorption fan noise insulation, have apparent syllable-dividing noise reduction effect (can effectively reduce 30 decibels), have simultaneously drop into low, easy to get one's hand, take effect fast advantage.
The utility model discloses a cavity structures by base, four baffles and upper cover constitution, be provided with the shock pad on the base, it has the through-hole to open on the baffle, and dust absorption fan is placed on the shock pad, and the dust absorption mouth is towards the through-hole. The upper cover is provided with a vertical downward L-shaped edge all around, the top of the partition board is provided with an inverted U-shaped structure, the outer edge of the inverted U-shaped structure is attached to the L-shaped edge of the upper cover, and the top edge of the inverted U-shaped structure is fixed to the upper cover through a connecting bolt.
Further improved, a sealing strip is arranged between the top edge of the inverted U-shaped structure and the upper cover.
Further improved, sound-absorbing cotton is paved on the inner surfaces of the base, the four partition plates and the upper cover.
The utility model has the advantages that:
1. sound insulation and absorption treatment: establishing a sound insulation screen for the fan, and arranging a sound absorption material to enable the periphery of the fan to be in a closed space and seal noise;
2. damping treatment: a damping pad and a rubber sealing strip are additionally arranged on the base of the fan and used between the closed partition plates.
3. The partition plate adopts a peripheral U-shaped structure, so that the strength of the partition plate is enhanced, vibration is reduced, a noise propagation channel is bent, and the sound insulation and noise reduction efficiency is further improved.
