Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for crushers, and in particular to a noise reduction device for a crusher for refractory materials. Background Technology

[0002] In the production of refractory materials, the crusher, as a key piece of equipment, undertakes the important task of crushing various blocky refractory raw materials into suitable particle sizes. Existing technology discloses a noise-reducing crushing device (application number 202022047229.4), including a frame. Several sound-insulating plates are welded to the upper end of the inner wall of the frame, and a crushing mechanism is located at the lower end of the sound-insulating plates. The crushing mechanism includes a first servo motor, a first crushing roller, a first rotating shaft, and a first hydraulic telescopic rod. The first servo motor is bolted to the outer wall of the frame, and the output shaft of the first servo motor extends through the frame into the interior, where the first crushing roller is fixed. In this invention, by opening the first and second hydraulic telescopic rods, the second servo motor moves, which in turn moves the second crushing roller, thereby changing the distance between the first and second crushing rollers to control the size of the crushed material, enhancing the applicability and practicality of the device. However, the existing technology still suffers from problems such as a single noise-reducing structure, limited sound insulation effect, and insufficient equipment adaptability. Therefore, we propose a noise-reducing device for a refractory material crusher to solve the above problems. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a noise reduction device for a refractory material crusher. This device enhances sound insulation through a multi-layer composite noise reduction structure, improves structural stability through reinforced support design, and features flexible adjustment and mobility to meet the noise reduction needs of various crusher models.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] A noise reduction device for a refractory material crusher includes a frame and a noise reduction cover. A crossbeam is fixedly connected to the top of the frame, and a telescopic push rod is fixedly installed in the middle of the lower end face of the crossbeam. The output end of the telescopic push rod is fixedly connected to the middle of the top of the noise reduction cover. The noise reduction cover is composed of an inner shell, a first connecting layer, a damping layer, a noise reduction and sound insulation layer, and an outer shell in sequence from the inside to the outside. Casters are fixedly installed at the four corners of the lower end face of the frame.

[0006] Furthermore, reinforcing support partitions are evenly distributed between the inner shell and the outer shell.

[0007] Furthermore, the reinforced support partition is arranged in a grid pattern, dividing the damping layer and the noise reduction and sound insulation layer into multiple independent cavities, and the reinforced support partition is made of lightweight alloy material with a thickness of 1-1.2mm.

[0008] Furthermore, the inner shell is made of perforated steel plate with a thickness of 2-2.5mm, and the inner wall of the inner shell is uniformly provided with sound-absorbing holes with a diameter of 4-6mm, the opening rate is 25%-30%, and the inner surface of the inner shell is sprayed with a high-temperature resistant and wear-resistant coating.

[0009] Furthermore, the first connecting layer is a modified acrylic adhesive.

[0010] Furthermore, the noise reduction and sound insulation layer is composed of alternating layers of ultrafine glass wool and polyurethane foam.

[0011] Furthermore, the outer shell is made of cold-rolled steel plate with a thickness of 3-3.5mm, and the outer wall is treated with electrostatic spraying to form an anti-corrosion layer.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Multi-layer composite noise reduction with significant sound insulation effect: The perforated structure of the inner shell, combined with the vibration energy loss of the damping layer and the multi-material acoustic impedance gradient change of the noise reduction and sound insulation layer, forms a synergistic effect of "absorption-blocking-insulation", which far exceeds the noise reduction effect of traditional single-layer sound insulation board.

[0014] 2. Stable and durable structure with strong adaptability: The grid-like reinforced support plate prevents the sound insulation material from being compacted due to vibration, thus extending its service life; the telescopic push rod can flexibly adjust the height of the outer cover, and the movable casters facilitate the relocation of the device, making it compatible with different models and installation positions of crushers, thus solving the problem of poor versatility of traditional devices.

[0015] 3. Convenient operation and comprehensive protection: The inspection port design takes into account both maintenance convenience and sound insulation and sealing; the high temperature and wear-resistant coating, anti-corrosion layer and shock-absorbing pads enable the device to adapt to the high temperature, dust and vibration environment when the crusher is working, improving long-term operational reliability.

[0016] In summary, the noise reduction device for this type of refractory material crusher has wide applicability, addressing the problems mentioned in the background art, such as the existing technology having a single noise reduction structure, limited sound insulation effect, and insufficient equipment adaptability.

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0022] like Figure 1 and Figure 2 As shown, the embodiment of this utility model includes a frame 1 and a noise reduction cover 4. A crossbeam 2 is fixedly connected to the top of the frame 1. A telescopic push rod 3 is fixedly installed in the middle of the lower end face of the crossbeam 2. The output end of the telescopic push rod 3 is fixedly connected to the middle of the top of the noise reduction cover 4. Movable casters 5 are fixedly installed at the four corners of the lower end face of the frame 1.

[0023] The noise reduction outer cover 4 is composed of an inner shell 401, a first connecting layer 402, a damping layer 403, a noise reduction and sound insulation layer 405, and an outer shell 406, which are sequentially combined from the inside to the outside. Reinforcing support partitions 404 are evenly distributed between the inner shell 401 and the outer shell 406.

[0024] The reinforcing support partition 404 is arranged in a grid pattern, which separates the damping layer 403 and the noise reduction and sound insulation layer 405 into multiple independent cavities. The reinforcing support partition 404 is made of lightweight alloy material with a thickness of 1-1.2mm.

[0025] The inner shell 401 is made of perforated steel plate with a thickness of 2-2.5mm. The inner wall of the inner shell 401 is uniformly provided with sound-absorbing holes with a diameter of 4-6mm, and the opening rate is 25%-30%. The inner surface of the inner shell 401 is coated with a high-temperature resistant and wear-resistant coating.

[0026] The first connecting layer 402 is a modified acrylic adhesive.

[0027] The noise reduction and sound insulation layer 405 is made of alternating layers of ultra-fine glass wool and polyurethane foam.

[0028] The outer casing 406 is made of cold-rolled steel plate with a thickness of 3-3.5mm, and the outer wall is treated with electrostatic spraying to form an anti-corrosion layer.

[0029] This device boasts several significant advantages. In terms of noise reduction, the multi-layered composite structure works synergistically. The sound-absorbing holes in the inner shell efficiently absorb noise generated during the crusher's operation, while the damping layer effectively suppresses noise from vibration. The alternating layers of ultra-fine glass wool and polyurethane foam in the noise-reducing and sound-insulating layer further enhance the sound insulation effect. The grid-like reinforced support partitions separate the damping and noise-reducing and sound-insulating layers into multiple independent cavities, reducing sound propagation and resonance, and significantly lowering noise pollution.

[0030] In terms of structural stability and durability, the reinforced support partition is made of lightweight alloy material, which ensures the support strength while reducing the overall weight; the high temperature and wear-resistant coating of the inner shell enables it to adapt to the high temperature and abrasion environment during the crushing of refractory materials; the cold-rolled steel plate material of the outer shell and the anti-corrosion layer formed by electrostatic spraying enhance the corrosion resistance of the device and extend its service life.

[0031] In terms of ease of operation, the casters at the bottom of the stand allow for flexible movement of the device and can be adjusted according to the position of the crusher; the telescopic push rod can easily control the raising and lowering of the noise reduction cover, making it convenient for the crusher to be inspected and maintained, and greatly improving the convenience of use.

[0032] All electrical components mentioned in the text are electrically connected to an external controller and power supply, and the controller can be a conventional known device such as a computer that provides control.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
