Analysis and summary of vibrating screen dust problem

At present, the dust status of many screening workshops is quite unoptimistic. For example, Weifang disinfectant customers need to operate with gas masks, Lianyungang customers wear masks, and even more, Shandong Yucheng sorbitol screening workshop specializes in screening. The house is also dusty inside. The surface of Liaoning metal powder customer workshop is blackened by dust, etc. At present, most of the vibration screening equipments are easy to vibrate and dust, but the reasons for the dust are comprehensively analyzed into the following two types: feeding dust and receiving dust.

The problem of feeding dust: It has a direct impact on the feeding tools on site. The dust generated by manual feeding, the equipment feeding equipment is connected with the soft link without sealing, and the dust generated directly.

The dust problem of the receiving material: the same is that the manual material is not protected, and the receiving equipment does not have a good sealing connection and so on.

If the system is not tightly sealed, it can be avoided by some sealing methods, and it is better to add a little negative pressure.

However, the avoidance of manual feeding and receiving dust is quite difficult to handle. The manual feeding process is also not conducive to screening. The screening equipment is required to continue uninterrupted quantitative feeding. Generally, the artificial feeding is to add a lot of materials to the equipment. Screening and sieving are almost re-feeding. This sifting operation not only causes a large amount of dust to fly, but also causes a decrease in the output and efficiency of the screening equipment (metal powder production drops by more than 60%).

The amount of dust generated by manual feeding is larger than that of manual feeding. The vibration of the material from the vibrating screening equipment is very small, but the amount of dust falling from the material falling into the pocket and the open barrel is quite large, difficult to control, and the damage is very high. Big.

Summary: The dust on the equipment site is not only a matter of polluting the environment, but we also spend the cost to manage it. More data we don't have statistics, every year because of the amount of products we lost? Because the environmental protection is not up to standard, we have to stop production and rectify and reduce production in order to cope with the national inspection. In order to make our future better, the governance environment is not a cure, we must eliminate pollution from production.

The problem of dust in the screening operation is caused by the vibrating screen itself. Adding negative pressure on the vibrating screen is a misunderstanding of the dust. The dust generated by analyzing the vibration of the vibration equipment itself is very limited. Only the negative pressure is applied to the vibration screening equipment, which cannot solve the dust problem in the screening workshop. It is necessary to analyze and control from the combination of feeding, receiving and transportation to complete.

Development direction The dust removal in the market is mostly large dust removal equipment, and it is a comprehensive dust removal for large spaces, such as screening systems. Such dust removal equipment has no targeted equipment for the time being. However, the dust removal of small systems improves the working environment and health of workers. This far-reaching significance is also the development direction of the screening system in the future.

The R&D direction combines some of the results of our company's net screen and smart screen to optimize and improve from the following three aspects:

Design and promotion of dust-free manual feeding equipment.

Design and promotion of dust-free manual feeders.

Design and promotion of dust-free clean screening systems.
