Sound insulation and noise reduction wall body of sound elimination and noise reduction movable operation room for machining

Abstract

The invention provides a sound insulation and noise reduction wall body of a sound elimination and noise reduction movable operation room for machining. The sound insulation and noise reduction wall body comprises dust isolation screen doors, sound absorption groove plates and sound absorption water tanks. A dust isolation screen door fixing frame is fixed to the upper side of a bottom face structure; the dust isolation screen doors are fixedly mounted on the dust isolation screen door fixing frame by rotary hinges; sound absorption cotton is fixedly pasted on one lateral wall face of a soundabsorption cotton wall body; the sound absorption groove plates are fixedly mounted on the sound absorption cotton wall body pasted with the sound absorption cotton; the sound absorption groove platesare arranged on the inner sides of the dust isolation screen doors; and the sound absorption water tanks are arranged on the rear sides of the sound absorption cotton wall body. According to the sound insulation and noise reduction wall body of the sound elimination and noise reduction movable operation room for machining, the sound absorption groove plates are arranged on the sound absorption cotton wall body at equal intervals, a layer of sound absorption cotton cloth structure is pastes on the sound absorption groove plates, so that noise absorption areas of the sound absorption groove plates are increased by array arrangement of the sound absorption groove plates, and therefore noise absorption effect can be improved and rapid spread of noise is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical sound insulation and noise reduction equipment, in particular to a sound insulation and noise reduction wall of a noise reduction and noise reduction mobile operation room for mechanical processing. Background technique [0002] The harm of noise to the human body is systemic, which can not only cause changes in the auditory system, but also affect the non-auditory system. The early stages of these effects are mainly physiological changes, and long-term exposure to relatively strong noise can cause pathological changes. In addition, the noise in the workplace can also interfere with language communication, affect work efficiency, and even cause accidents. [0003] Especially in the process of mechanical production, the noise is very loud. For example, the noise of mechanical equipment such as punch presses is more severe, and the harm to the human body is more serious. Therefore, it is necessa...

Problems solved by technology

[0008] The object of the present invention is to provide a sound-insulating and noise-reducing wall of a noise-reduction and noise-reduction mobile operation room for mechanical processing, so as to solve the problem that the conventional noise-reduction and noise-reduction wall proposed in the above-mentioned background technology has a simple structure, a single method of sound insulation and noise reduction, and absorbs noise. The effect is poor, and the noise cannot be absorbed multiple times; moreover, the existing wall structure does not have the settings to slow down the speed of noise transmission, so that the absorption time of the sound-absorbing device cannot be increased, and the noise caused by it is transmitted, thus forming invisible noise pollution The problem
