Low-noise Environmentally Friendly Shot Blasting Machine

In recent years, with the continuous improvement of global environmental protection awareness and the increasingly strict environmental protection laws and regulations, the manufacturing industry has put forward higher requirements for the environmental performance of equipment. The shot blasting machine, as a common surface treatment equipment, usually generates large noise and dust during the working process, which has a great impact on the environment and the health of operators. The Low-noise Environmentally Friendly Shot Blasting Machine is a new type of shot blasting equipment developed to solve these problems. It adopts a series of noise reduction and environmental protection technologies, which can effectively reduce the noise generated during the working process and control the dust emission within the national environmental protection standards. This article will deeply discuss the Low-noise Environmentally Friendly Shot Blasting Machine from the aspects of noise reduction principle, environmental protection technology, structural composition, core advantages, application scenarios, performance testing, and daily maintenance, to show its important role in promoting the green development of the manufacturing industry.

The noise generated by the traditional shot blasting machine during the working process mainly comes from the following aspects: the high-speed rotation of the impeller head, the impact of the shot material on the workpiece and the inner wall of the shot blasting chamber, the operation of the fan and the motor, and the vibration of the equipment. The noise not only affects the working environment of the workshop but also causes great harm to the hearing of the operators. The Low-noise Environmentally Friendly Shot Blasting Machine adopts a variety of noise reduction technologies to reduce the noise from the source and the transmission process. First, in terms of the impeller head, the machine adopts an optimized impeller structure design. The shape and size of the impeller and blade are redesigned to reduce the air resistance during the rotation of the impeller and the noise generated by the high-speed airflow. At the same time, the impeller and blade are made of high-quality wear-resistant materials with good dynamic balance performance, which can reduce the vibration and noise generated by the unbalanced rotation of the impeller. Second, in the shot blasting chamber, the inner wall of the chamber is lined with high-performance sound-absorbing and noise-reducing materials, such as sound-absorbing cotton, rubber plates, etc. These materials can absorb the noise generated by the impact of the shot material on the inner wall of the chamber and reduce the reflection and transmission of the noise. Third, the machine adopts a fully enclosed structure design. The shot blasting chamber, impeller head, fan, and other components are all enclosed in the machine body, which can effectively block the transmission of noise to the outside. Fourth, in terms of the fan and motor, the machine adopts low-noise fan and motor. The fan is equipped with a silencer, which can reduce the noise generated by the airflow of the fan. The motor is installed with a shock absorber, which can reduce the vibration and noise generated by the operation of the motor. Fifth, the machine is equipped with a vibration isolation device. The whole machine is installed on the vibration isolation pad, which can reduce the vibration of the machine and the noise transmitted through the foundation.

The environmental protection performance of the Low-noise Environmentally Friendly Shot Blasting Machine is mainly reflected in the effective control of dust emission. The dust generated during the shot blasting process is the main source of pollution of the shot blasting machine. The machine adopts a high-efficiency dust removal system to control the dust emission. The dust removal system usually includes a dust collector, air duct, fan, and other components. The dust collector adopted by the machine is usually a high-efficiency dust collector, such as a cartridge dust collector, bag dust collector, etc. These dust collectors have high dust removal efficiency and can remove more than 99.9% of the dust in the gas. At the same time, the dust removal system adopts a negative pressure design. The dust-laden gas generated during the shot blasting process is sucked into the dust collector through the air duct under the action of the fan, and the purified gas is discharged into the atmosphere. The negative pressure design can prevent the dust from leaking from the shot blasting chamber and other parts, ensuring the cleanliness of the working environment. In addition, the machine also adopts measures such as oil mist collection and treatment for the oil mist generated during the working process, to avoid oil mist pollution to the environment.

The structural composition of the Low-noise Environmentally Friendly Shot Blasting Machine is mainly composed of shot blasting chamber, impeller head (low-noise design), high-efficiency dust removal system, noise reduction system, electrical control system, and other components. The shot blasting chamber is of fully enclosed structure, and the inner wall is lined with sound-absorbing and wear-resistant materials. The impeller head adopts an optimized structure design and is equipped with a noise reduction cover. The high-efficiency dust removal system is composed of a cartridge dust collector, air duct, fan, and silencer. The noise reduction system includes sound-absorbing materials, silencers, shock absorbers, and vibration isolation pads. The electrical control system adopts PLC control, which can realize the automatic control of the machine and monitor the operation status of the equipment in real time. The machine is also equipped with safety protection devices, such as safety doors, emergency stop buttons, etc., to ensure the safety of operators.

The Low-noise Environmentally Friendly Shot Blasting Machine has many core advantages compared with traditional shot blasting machines. First of all, it has excellent noise reduction performance. The noise generated during the working process of the machine is usually below 85 decibels, which meets the national noise emission standards and greatly improves the working environment of the workshop. Second, it has high-efficiency environmental protection performance. The high-efficiency dust removal system can effectively control the dust emission, and the emission concentration of dust is far lower than the national environmental protection standards. At the same time, the machine also takes measures to control oil mist and other pollutants, which is conducive to protecting the ecological environment. Third, it has stable and reliable operation performance. The machine adopts high-quality components and advanced manufacturing processes, which have good wear resistance and corrosion resistance. The noise reduction and dust removal systems are designed reasonably, ensuring the stable operation of the machine for a long time. Fourth, it has strong adaptability.
