In the process of shot blasting, the generation of dust is an inevitable problem. A large amount of dust not only pollutes the working environment, endangers the health of operators but also affects the cleaning effect of the workpiece and the normal operation of the equipment. Therefore, the dust removal system is an important part of the shot blasting machine, and its performance directly determines the environmental protection, safety, and reliability of the equipment. The shot blasting machine with 3500m³/h high air volume dust removal has become a new favorite in the market due to its powerful dust removal capacity. This article will comprehensively introduce this type of shot blasting machine, including the working principle of the high air volume dust removal system, the structural characteristics of the equipment, the advantages of high air volume dust removal, application scenarios, and its role in promoting green production.

First, it is necessary to understand the working principle of the 3500m³/h high air volume dust removal system. The core of the dust removal system of the shot blasting machine is to collect and filter the dust generated during the shot blasting process. The 3500m³/h high air volume dust removal system mainly consists of a dust hood, a dust collection pipeline, a high-pressure fan, a filter device, and an ash discharge device. During the operation of the shot blasting machine, the dust hood installed at the shot blasting chamber and other key positions will quickly capture the generated dust. Under the action of the high-pressure fan, the dust is sucked into the dust collection pipeline and transported to the filter device. The filter device adopts high-efficiency filter materials, such as bag filters or cartridge filters, which can effectively filter the dust particles in the air. The filtered clean air is discharged into the atmosphere through the fan, and the collected dust is discharged through the ash discharge device for centralized treatment. The 3500m³/h air volume means that the dust removal system can process 3500 cubic meters of dusty air per hour, which is much higher than that of ordinary shot blasting machines, ensuring that the dust generated during the shot blasting process can be quickly and thoroughly removed.

The shot blasting machine with 3500m³/h high air volume dust removal has unique structural characteristics to match the high air volume dust removal system. First, the shot blasting chamber is designed with a sealed structure. The sealing performance of the shot blasting chamber directly affects the dust removal effect. If the sealing is not tight, the dust will leak from the gaps, polluting the working environment. Therefore, this type of shot blasting machine adopts high-quality sealing materials and a reasonable sealing structure for the shot blasting chamber, such as rubber seals, felt seals, etc., to ensure that the shot blasting chamber is in a sealed state during operation, preventing dust leakage. Second, the dust hood is designed in a multi-point and multi-angle manner. According to the distribution of dust generation points in the shot blasting process, multiple dust hoods are installed at key positions such as the shot blasting wheel outlet, the workpiece inlet and outlet, and the shot recycling system. Each dust hood has a reasonable size and angle to ensure that all dust generation points are covered, and the dust can be captured to the maximum extent. Third, the dust collection pipeline adopts a large-diameter design. The large-diameter pipeline can reduce the resistance of air flow, ensure that the dust-laden air can be transported smoothly, and avoid the blockage of the pipeline caused by the accumulation of dust. At the same time, the pipeline is equipped with a cleaning device, which can regularly clean the pipeline to ensure the smoothness of the pipeline.

The high-pressure fan is the power source of the 3500m³/h high air volume dust removal system, and its performance directly determines the air volume and wind pressure of the dust removal system. This type of shot blasting machine is usually equipped with a high-power, high-efficiency centrifugal fan. The centrifugal fan has the advantages of large air volume, high wind pressure, and stable operation, which can provide sufficient power for the dust removal system to ensure that the dust-laden air is quickly sucked and transported. The fan is equipped with a frequency conversion control device, which can adjust the speed of the fan according to the amount of dust generated during the shot blasting process, thereby adjusting the air volume. When the amount of dust is large, the fan speed is increased to increase the air volume; when the amount of dust is small, the fan speed is reduced to save energy. This not only ensures the dust removal effect but also realizes energy saving and emission reduction.

The filter device of the 3500m³/h high air volume dust removal system is an important part to ensure the dust removal efficiency. At present, the commonly used filter devices include bag filters and cartridge filters. The bag filter uses filter bags made of high-temperature resistant, corrosion-resistant, and high-efficiency filter materials. The dust-laden air passes through the filter bags, and the dust particles are trapped on the surface of the filter bags, and the clean air passes through the filter bags and is discharged. The bag filter has the advantages of high dust removal efficiency, large dust holding capacity, and strong adaptability to dust, which can effectively filter fine dust particles. The cartridge filter uses filter cartridges made of folded filter paper or non-woven fabric. It has the advantages of small volume, high filtration precision, and easy replacement. The 3500m³/h high air volume dust removal system can choose the appropriate filter device according to the characteristics of the dust generated by the shot blasting machine and the requirements of environmental protection. At the same time, the filter device is equipped with an automatic ash cleaning device, such as a pulse jet ash cleaning device. The pulse jet ash cleaning device can regularly spray high-pressure air into the filter bags or filter cartridges to remove the dust accumulated on the surface, ensuring the stable operation of the filter device and the continuity of the dust removal effect.

The shot blasting machine with 3500m³/h high air volume dust removal has many advantages compared with ordinary shot blasting machines. First, it has excellent dust removal effect. The 3500m³/h high air volume can quickly and thoroughly collect the dust generated during the shot blasting process, ensuring that the concentration of dust in the working environment is far lower than the national standard limit, protecting the health of operators. According to the national occupational health standard, the allowable concentration of total dust in the air of the workplace is not more than 8mg/m³. The 3500m³/h high air volume dust removal system can control the dust concentration below 2mg/m³, which is much higher than the national standard. Second, it can avoid secondary pollution of the workpiece. The dust generated during the shot blasting process will not adhere to the surface of the workpiece again due to the rapid collection of the high air volume dust removal system, ensuring the cleaning effect of the workpiece and improving the quality of the workpiece. Third, it can protect the equipment. The dust generated during the shot blasting process contains a lot of hard particles, which will cause wear and damage to the moving parts of the equipment, such as the shot blasting wheel, bearing, and reducer, if they are not removed in time. The high air volume dust removal system can reduce the wear of the equipment by removing the dust, extending the service life of the equipment. Fourth, it is conducive to environmental protection. The filtered clean air meets the national emission standards, and the collected dust can be centralized treated, reducing the impact on the environment. It complies with the requirements of the national environmental protection policy and avoids the risk of environmental pollution caused by enterprises.

This type of shot blasting machine has a wide range of application scenarios, especially in industries with high requirements for environmental protection and large dust generation during the shot blasting process.
