Some devices use soundproofing materials with poor sound insulation properties, or are susceptible to environmental corrosion over long-term use, affecting the stability of their soundproofing effect. Furthermore, existing soundproofing devices are complex in structure, cumbersome to install and maintain, and difficult to quickly locate and secure, impacting the normal operation and maintenance efficiency of the equipment. To address these issues, this device was invented. Utility Model Content

[0025] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] See attached document Figures 1-4 The sound insulation device for a photovoltaic silica sand production ball mill according to this embodiment includes a support frame 1 and a sound insulation cover 2.
[0027] See attached document Figures 1-3 The support frame 1 is a detachable structure, including multiple support columns 101 and connecting plates 102. The connecting plates 102 are made of polyester fiber sound-absorbing panels, which have good sound absorption performance and can initially absorb the noise generated by the ball mill. Specifically, there are four support columns 101, which are located at the four corners of the top of the ball mill base. There are four connecting plates 102. Insertion slots 103 are opened on the facing surfaces of two adjacent support columns 101. The four connecting plates 102 are respectively inserted between two adjacent support columns 101. The support columns 101 and the connecting plates 102 are fixed by bolts. The support columns 101 are connected to the base of the ball mill by bolts.
[0028] As an alternative, the number of support columns 101 and connecting plates 102 can also be five, six, etc., to accommodate ball mills of different shapes.
[0029] See attached document Figure 4The bottom of the soundproof cover 2 is open, and it includes an outer steel plate 201, a middle sound insulation layer 202, and an inner sound insulation layer 203, forming multiple sound barriers to effectively reduce noise transmission. The outer steel plate 201 is made of 2mm thick cold-rolled steel plate to protect the internal sound insulation material, prevent external environment from corroding the sound insulation layer, and provide structural strength. The middle sound insulation layer 202 is made of ultra-fine glass wool, which has excellent sound absorption and sound insulation performance and can effectively absorb and reflect sound waves. The inner sound insulation layer 203 is made of polyester fiber sound-absorbing cotton, which has high density, low water absorption and good sound insulation effect, further absorbs sound waves, prevents noise from being reflected back into the ball mill, and enhances the sound insulation effect.
[0030] See attached document Figure 3 A guide rod 4 is fixedly installed on the inner wall of the connecting plate 102. The soundproof cover 2 has guide grooves 5 on all four sides that are compatible with the guide rod 4. The soundproof cover 2 is connected to the support frame 1 through the guide rod 4 and the guide grooves 5. The design of the guide rod 4 and the guide grooves 5 makes the installation of the soundproof cover 2 more convenient, and can be quickly positioned and fixed, ensuring that the soundproof cover 2 will not be displaced or shaken during operation, thus improving the stability of the sound insulation effect.
[0031] Lifting rings 3 are fixedly installed at the four corners of the top of the soundproof cover 2, providing lifting points to facilitate lifting with cranes or other lifting equipment, reducing the difficulty and risk of manual handling.
[0032] A first observation window is provided on the connecting plate 102, and a second observation window is provided on each of the four sides of the soundproof cover 2. The first and second observation windows correspond to each other, which facilitates the observation of the operating status of the ball mill. Both the first and second observation windows are made of transparent soundproof glass. The transparent soundproof glass ensures the clarity of observation without affecting the sound insulation effect.
[0033] A ventilation opening is provided in the middle of the top of the soundproof cover 2, and a cooling fan (not shown in the figure) is installed in the ventilation opening to ensure that the heat generated during the operation of the ball mill can be discharged in time, so as to avoid the normal operation of the equipment due to excessive temperature.
[0034] This technical solution effectively isolates and absorbs the noise generated during the operation of the ball mill through a detachable support frame 1 and a multi-layered soundproof cover 2. The detachable design of the support frame 1 and the use of polyester fiber sound-absorbing panels ensure both ease of installation and maintenance and initial noise absorption. The combination of the outer steel plate 201, the middle sound insulation layer 202, and the inner sound insulation layer 203 of the soundproof cover 2 provides a strong sound insulation effect. The design of the guide rod 4 and the guide groove 5 ensures the stability and ease of installation of the soundproof cover 2. The installation of the lifting ring 3, the observation window, and the ventilation opening further enhances the practicality of the equipment, ensuring the normal operation of the ball mill and the convenience of the operators.
