Influence of dust removal effect of road shot blasting machine
The dust collector is the supporting equipment of the road shot blasting machine. It is connected to the shot blasting equipment through the connecting pipe to provide a certain amount of negative pressure to separate the shot and impurities. It can be said that the impact of the dust removal device on the entire cycle process of the road shot blasting machine is very important. Its performance directly affects the throwing effect of the road shot blasting machine and the recovery effect of the projectile. The dust collector is mainly composed of: fan, vacuum chamber, back blowing system, dust collection system, etc. Let us briefly talk about the functions of each component: the fan provides negative pressure; the vacuum chamber is equipped with a certain number of filter elements to separate impurities in the air ; The back blowing system provides compressed air to automatically clean the filter element at a certain frequency; the dust collection system collects the impurities filtered by the filter element for later processing. All parts of the dust collector work together to achieve the best effect of dust removal.
According to theoretical analysis and long-term experiments, Chengdu Shugong Machinery Co., Ltd. believes that the main factors affecting the dust removal of road shot blasting machines are as follows:
1. Fan: The fan is a part of the dust collector, it provides negative pressure, and the air volume provided by the fan is the first element to ensure the dust removal of the dust collector, which adsorbs the dust to the surface of the filter element.
2. The sealing of the whole device: the quality of the sealing performance directly affects the size of the negative pressure. The biggest impact on sealing is the gap between the dust collector's dust chamber and the dust collection system. Installing soft rubber between the two can have a good sealing effect.
3. Backflushing device: The automatic backflushing device is mainly composed of a timing controller and a pulse valve. The pulse valve is controlled by the sequence controller, and then the rotation and cleaning of the filter element and the operating frequency of the compressor are controlled.
4. The length and arrangement of the dust removal pipe: The dust removal pipe plays the role of connecting the shot blasting machine and the dust collector. The dust enters the dust collector from the shot blasting machine through the dust removal pipe. If the dust removal pipe is too long, it will increase the loss of air volume, resulting in insufficient negative pressure in the dust removal pipe, which will affect the dust removal effect. The dust removal pipe cannot be placed at will during work. It is found through experiments that the dust removal effect is best when the dust removal pipe is arranged in an arcuate shape.
Referring to the above analysis, we know that the working performance of the dust collector is affected by many factors, and the working effect of the road shot blasting machine is not only related to the working effect of the dust removal device, but also affected by many other factors. In actual work, we need to combine many factors, consider all aspects, and make appropriate adjustments to individual factors, so that the entire cycle process of the road shot blasting machine can be smoothly realized and the desired effect can be achieved. The factors summarized by our company have certain guiding significance for theoretical research and experiment of dust removal device, and also have certain reference value for studying the blasting effect and blasting efficiency of shot blasting machine. While improving the dust removal device, it is also helpful to improve the service life of the road shot blasting machine.
