Ventilated and sound-absorbing suction chamber

Abstract

The invention discloses a ventilated and sound-absorbing suction chamber, which comprises a wall (1) with a cavity, an air inlet (2) is opened on the outer wall of the wall, and an air inlet (2) is opened on the inner wall of the wall. The air outlet (3), the first annular sound insulation board (4) and the second annular sound insulation board (5) distributed horizontally are arranged at intervals in the cavity from top to bottom, and the first annular sound insulation board is provided with The first through hole (6), the bottom of the first through hole is connected with a tapered cylinder (7) whose diameter gradually expands downward, the second annular sound insulation board passes through the conical cylinder, and the second annular The sound insulation board is a hollow structure, and there are several springs (8) fixedly connected to the inner side of the wall around the center of the second ring-shaped sound insulation board, and the ends of the springs are connected with sliders (9). The invention has the beneficial effects of simple structure, low production cost and good effects of ventilation and sound insulation.

Description

technical field [0001] The invention relates to the field of building curtain walls, in particular to an air suction chamber for industrial workshops. Background technique [0002] Ventilation and sound insulation of buildings have always been two mutually restrictive requirements. How to reduce noise under the premise of ensuring ventilation has always been the goal pursued by people. At present, the common industrial plant computer room, air compressor room and other rooms that need to be ventilated mostly use the combination of suction chamber + mechanical ventilation. It is composed of an outdoor air cover with vents and a through-wall air duct; specifically, the through-wall air duct runs through the wall, and a ventilator is installed on the mouth of the indoor end, and the outdoor end of the air duct extends into the outdoor air duct. The inside of the hood; in the process of working, after the fan is turned on, the outdoor air enters the room through the vent and th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing suction chamber has the defect that both ventilation and sound insulation cannot be achieved at the same time. Therefore, a ventilation and sound-absorbing suction chamber with excellent sound insulation effect is provided without affecting the ventilation as much as possible.
