SOUNDPROOFING CASING Russian patent published in 2018 - IPC E04B1/82 G10K11/16 

FIELD: soundproofing.

SUBSTANCE: invention relates to acoustic isolation of equipment with means of broadband acoustic suppression and can be used in all sectors of the national economy as a means of protection against noise. Soundproofing casing is made in the form of a rectangular parallelepiped covering technological equipment, technological equipment is installed on at least four vibration-proof supports, that are based on the bridging of the building. Between the process equipment base and the cutout in the rectangular parallelepiped lower face, a gap is made designed to prevent the vibrations transfer from the process equipment to the soundproof enclosure of the casing, and to provide the required microclimate during carrying out the process, the fan is installed inside the casing. In the soundproof enclosure, ventilation ducts are made to eliminate equipment overheating. Internal walls of the ventilation ducts are treated with a sound-absorbing material and an acoustically transparent material of the "poviden" type. Casing includes noise suppressors, installed respectively on the inlet and outlet ventilation ducts. On the inner surface of the soundproofing enclosure the sound-absorbing element in the form of the smooth and perforated surface is fixed, between which the multi-layer sound-absorbing structure is located. Each of the four vibration isolation supports of the vibration isolation system of the process equipment is made in the form of a spring-loaded vibration, comprising a body and an elastomeric elastic member cooperating with the object, the body is made in the form of a base, a lid with a collar and a spherical recess, with which the hairpin interacts with a spherical belt at the end having increased hardness, and the elastic element is made of an elastomer in the form of a package of elastic elements, located along the trajectory of axisymmetric concentric circles in an intermediate element having a central hole and slots for fixing the elastic members.

EFFECT: technical result is to increase the efficiency of noise suppression.
