Problems solved by technology

For workshops that require large-scale equipment to enter and exit, the door opening is relatively large (more than ten meters in length and width), and the traditional hinge sealing structure has the following disadvantages: ① Huge airtight doors are heavy after being filled with sound-absorbing and sound-insulating materials , just relying on the hinges to bear the weight of the entire door is a potential safety hazard; ② Due to the large size of the door opening and no special pressing device, there will be a gap between the door and the wall, and high-decibel noise is transmitted through the gap Finally, it will produce howling, which will greatly affect the sealing effect of the entire soundproof room

Abstract

The invention discloses a large soundproof sealing device for a door opening and belongs to the technical field of sound-proof sealing treatment for a roof door opening. The large soundproof sealing device comprises a circular seal strip and a door plate movably disposed on the circular seal strip. The circular seal strip is of a square structure and disposed around the door opening. The circular seal strip comprises a frame and elastomer disposed on the frame. The door plate comprises a left door and a right door and further comprises a left travelling mechanism and a right travelling mechanism; the left travelling mechanism allows the left door to move vertically and transversely; the right travelling mechanism allows the right door to move vertically and transversely. The left and right doors and the door opening are compressively sealed by means of butt-fastening seal strips. Combination of the two sealing manners enable the whole door opening to be seamlessly sealed; the large soundproof sealing device is simple in structure and good in soundproof and denoising effect; special sealing equipment formed of the large soundproof sealing device has a high market value.

Description

technical field [0001] The invention belongs to the technical field of sound insulation and sealing treatment for roof door openings, and in particular relates to a sound insulation sealing device for large door openings. Background technique [0002] Now many factory workshops have some large equipment (large engines, gearboxes, etc.), these equipment will produce strong noise due to reasons such as high power and low precision of the transmission system, and sometimes the sound pressure can reach more than 130 dB(A) (according to national standards , Occupational exposure for 8 hours, the allowable standard for workplace noise is 85dB(A)). Noise seriously endangers human health. Long-lasting excessive noise will have adverse effects on the central nervous system, such as emotional depression, decreased attention, slow response, etc. Excessive noise will cause damage to auditory organs, resulting in tinnitus, deafness, etc. symptom. In recent years, the state and society ...
