Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, specifically to a sound insulation board for noise reduction in industrial equipment. Background Technology

[0002] Ball mills and other crushing equipment generate significant noise during operation. According to the "Design Code for Noise Control in Industrial Enterprises," noise levels in production workshops and work areas of industrial enterprises should be controlled below 85 decibels. Prolonged work in noisy environments can cause hearing damage and nervous stress among workers. Currently, finished sound insulation panels are generally categorized into single-layer bent and perforated metal sound insulation panels, asbestos boards and polyester boards used in construction projects, and on-site fabricated sound insulation panels with a keel and sound insulation cotton. These are generally suitable for highways, office areas, and similar locations. However, sound insulation panels suitable for harsh industrial environments that are moisture-resistant, dust-resistant, and have a long lifespan are relatively rare. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a sound insulation board for noise reduction in industrial equipment.

[0004] This utility model is achieved through the following technical solution: providing a sound insulation board for noise reduction of industrial equipment, comprising a galvanized flat plate, a damping sound insulation felt, a glass fiber sound-absorbing board, a non-woven fabric, and a perforated aluminum plate that are sequentially bonded together.

[0005] As an optimization, the system also includes a channel steel, in which the galvanized flat plate, damping sound insulation felt, glass fiber sound-absorbing board, non-woven fabric and perforated aluminum plate are all inserted into the slot of the channel steel.

[0006] As an optimization, the thickness of the damping sound insulation felt is 2.5 mm, and the thickness of the glass fiber sound-absorbing board is 50 mm.

[0007] As an optimization, the damping sound insulation felt is fixed to the galvanized plate by grease adhesive.

[0008] As an optimization, the perforated aluminum plate is provided with multiple round holes.

[0009] The beneficial effects of this utility model are as follows: This utility model provides a sound insulation board for noise reduction in industrial equipment. A layer of non-woven fabric is placed inside a perforated aluminum plate, effectively isolating external dust and preventing blockage of the glass fiber sound-absorbing fibers, thus reducing the sound insulation effect. It also provides primary noise separation and vibration damping. Using a 50mm thick glass fiber sound insulation board, the pore separation effect of the glass fiber and its relatively soft material effectively reduce noise vibration and provide a damping effect. Simultaneously, noise is fully dispersed and reduced. A special grease adhesive is used to tightly bond the damping sound insulation felt to the galvanized plate, providing a third layer of sound absorption and isolation. Ultimately, this greatly improves the harsh noise environment, effectively protecting the working environment and physical and mental health of workers, aligning with the current people-oriented and sustainable development philosophy. The surfaces in contact with the external environment are made of galvanized steel and aluminum plates, which have significant advantages in resisting moisture and corrosion in humid environments, greatly increasing the service life of the sound insulation board. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model;

[0011] As shown in the figure:

[0012] 1. Channel steel, 2. Galvanized flat plate, 3. Damping sound insulation felt, 4. Fiberglass sound-absorbing board, 5. Non-woven fabric, 6. Perforated aluminum plate. Detailed Implementation

[0013] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0014] like Figure 1 As shown, the present invention provides a sound insulation board for noise reduction of industrial equipment, comprising a galvanized flat plate 2, a damping sound insulation felt 3, a glass fiber sound-absorbing board 4, a non-woven fabric 5, and a perforated aluminum plate 6, which are sequentially bonded together.

[0015] The galvanized flat plate 2 and the perforated aluminum plate 6 are located on the two surfaces of the entire sound insulation panel that are in contact with the outside world.

[0016] The use of galvanized and aluminum materials greatly increases the sound insulation panel's resistance to moisture and corrosion, and its service life can reach more than 10 years in non-harsh environments. Among them, the perforated aluminum plate 6 faces the noise side.

[0017] The glass fiber sound-absorbing panel 4 has a thickness of 50mm. Utilizing the pore separation effect of glass fiber and its relatively soft material, it effectively achieves secondary separation and vibration damping / sound absorption.

[0018] The damping sound insulation felt 3 is 2.5mm thick and is fixed to the galvanized plate 2 with grease adhesive. This ensures the damping sound insulation felt 3 is tightly bonded to the galvanized plate 2, providing a third-level sound absorption and isolation effect.

[0019] The perforated aluminum plate 6 has multiple round holes. The dense arrangement of round holes serves to absorb sound. The non-woven fabric effectively blocks external dust, preventing the sound-absorbing fibers on the glass fiber sound-absorbing panel 4 from becoming clogged and reducing the sound insulation effect. It also plays a role in noise separation and vibration damping.

[0020] It also includes channel steel 1, of which two channels are provided, located on the two parallel sides of the structure formed by galvanized flat plate 2, damping sound insulation felt 3, fiberglass sound absorbing board 4, non-woven fabric 5, and perforated aluminum plate 6.

[0021] The galvanized flat plate 2, damping sound insulation felt 3, glass fiber sound absorption board 4, non-woven fabric 5 and perforated aluminum plate 6 are all inserted into the slot of the channel steel 1, thereby achieving end wrapping.

[0022] Most of the equipment noise is absorbed through the round holes of the perforated aluminum plate 6, then through the pores of the non-woven fabric 5 for secondary isolation and absorption, then through the glass fiber sound-absorbing plate 4 for most of the noise damping and noise reduction, then through the damping sound insulation felt 3 for sound insulation and noise reduction, and finally through the galvanized plate 2 for final noise isolation to achieve the final noise reduction effect.

[0023] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
