Acrylic fiber yarn production noise reduction device

Abstract

The invention discloses a noise reduction device for acrylic yarn production, which comprises a base, shock absorbing rods are fixed at the four corners of the bottom outer wall of the base by screws, and a mounting plate is fixed on the bottom outer wall of the shock absorbing rod by screws. The top outer wall of the base is fixed with a shock-absorbing plate by screws, and one side of the top outer wall of the shock-absorbing plate is fixed with an equipment box by screws, and the top inner wall of the equipment box is fixed with a cooling fan by screws, and the equipment box is close to the cooling fan. A second temperature sensor is fixed on the top inner wall of the side by screws, a cooling plate is fixed on the inner wall of one side of the equipment box by screws, and a circulation pipe is fixed on the outer wall of the cooling plate by screws. The invention can play a good damping effect, reduce the noise generated by the vibration when the motor is working, avoid the pollution of the surrounding environment caused by the noise, create a good workshop environment, avoid the occurrence of equipment burnout, and significantly improve the the service life of the equipment.

Description

technical field [0001] The invention relates to the technical field of noise reduction devices, in particular to a noise reduction device for acrylic yarn production. Background technique [0002] Acrylic fiber is the trade name of polyacrylonitrile fiber in my country. Acrylic fiber has excellent performance. Because its properties are close to wool, it is called "synthetic wool". Since its industrial production in 1950, it has been greatly developed. The total output is 2.52 million tons, and my country's output is 297,000 tons. In the future, my country will vigorously develop acrylic fiber production. Although acrylic fiber is usually called polyacrylonitrile fiber, acrylonitrile (customarily called the first monomer) only accounts for 90% to 94%. %, the second monomer accounts for 5% to 8%, and the third monomer is 0.3% to 2.0%. This is because the fiber made of a single acrylonitrile polymer lacks flexibility, is brittle, and is very difficult to dye. In order to overcom...

Problems solved by technology

[0003] In the acrylic yarn production workshop, most of the production machines are driven by motors. When the motors work, they will generate a lot of noise, so noise reduction treatment is required. The existing noise reduction devices have a simple design structure and a single function. The noise effect is poor, and the noise reduction problem cannot be solved fundamentally, and it is obviously unable to meet people's needs
