Analysis and summary of dust problems of vibrating screen

At present, the dust status of many screening workshops is not optimistic For example, Weifang disinfectant customers need to operate with gas masks, Lianyungang customers need to operate with masks What's more, Shandong Yucheng sorbitol screening workshop has built a screening room specially, and the dust flies in disorder At present, most of Liaoning metal powder customer workshop walls are black by dust, etc most of them think that the vibrating screening equipment is easy to vibrate and raise dust, but through comprehensive analysis, the causes of raise dust can be divided into the following two kinds: feeding raise dust and receiving raise dust Problem of feeding dust: it has a direct impact on the feeding tools on site The dust generated by manual feeding and the connection of equipment feeding equipment has no sealed soft link, which directly produces dust Dust problem of material receiving: it is also caused by dust flying caused by manual material receiving without protection and poor sealing connection with material receiving equipment It can be avoided by some sealing methods if the sealing of the system is not strict, and it is better to add a little negative pressure
However, it is quite difficult to avoid the dust of manual feeding and receiving, and the manual feeding process is not conducive to screening The screening equipment is required to continuously and quantitatively feed materials Generally, manual feeding is to add a lot of materials to the equipment for screening, and screening is almost re feeding Such screening operation not only causes a lot of dust flying, but also causes screening The output and efficiency of the equipment are reduced (the output of metal powder is reduced by more than 60%) The amount of dust produced by manual material receiving is larger than that produced by manual material feeding The vibration dust generated by materials coming out of the vibration screening equipment is very small However, the amount of dust raised by the secondary flying of materials falling into the pocket and the open barrel is quite large, which is difficult to control and does great harm Overview: the dust on the equipment site is not only a problem that pollutes the environment and endangers human beings, but also a problem that we spend more cost to control More data we don't have statistics on the amount of products we lose every year due to dust? And because environmental protection is not up to standard, we have to stop production for rectification and reduce production in response to national inspection In order to have a better tomorrow, we must stop pollution from production The problem of dust in screening operation is caused by the vibrating screen itself Adding negative pressure to the vibrating screen is a mistake to solve the problem of dust Through the analysis of the vibration equipment itself, the dust produced by vibration is actually very limited Only adding negative pressure to the vibration screening equipment can not solve the dust problem in the screening workshop It needs to analyze and control from the aspects of feeding, receiving and transportation The direction of development: most of the dedusting equipment in the market is large-scale dedusting equipment, and it is comprehensive dedusting for large space, such as screening system This kind of dedusting equipment has no targeted equipment temporarily However, the dedusting of small system has far-reaching significance for improving the working environment and health of workers, and it is also the development direction of screening system in the future The research and development direction combines some achievements of our company's clean screen and intelligent screen to optimize and improve from the following three aspects: the design and promotion of dust-free artificial feeding equipment Design and popularization of dust-free manual feeder The design and promotion of clean and dust-free screening system Xinxiang Gaofu Screening Machinery Co., Ltd sets up the screen department to respect the customer: if you are lucky to see this article, and you are troubled by the dust pollution on site, please let us Our technical team will tailor the production process to meet the needs of the site according to the situation of your site.
