Influence of dust removal effect of road shot blasting machine
The dust collector is a supporting equipment of the road shot blasting machine. It is connected to the shot blasting equipment through a connecting pipe to provide a sufficient certain amount of negative pressure to separate the shot material and impurities. It can be said that the impact of the dust removal device on the entire cycle of the road shot blasting machine is very important, and its performance directly affects the polishing effect of the road shot blasting machine and the recovery effect of the projectile. The dust collector is mainly composed of: fan, dust collection room, blowback system, dust collection system, etc. Let's briefly talk about the functions of each component: the fan provides negative pressure; the dust collection room 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.
Based on theoretical analysis and long-term testing, 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, and it absorbs the dust to the surface of the filter element.
2. The sealing of the entire device: the sealing performance directly affects the magnitude of the negative pressure. The biggest impact on the seal is the gap between the dust collector's vacuum chamber and the dust collection system. Installing soft rubber between the two can achieve a good sealing effect.
3. Back-blowing device: The automatic back-blowing device is mainly composed of a timing controller and a pulse valve. The pulse valve is controlled by the timing controller, which in turn controls the rotation cleaning of the filter element and the working frequency of the compressor.
4. The length and arrangement of the dust removal pipe: The dust removal pipe serves to connect the shot blasting machine and the dust collector. Dust enters the dust collector from the shot blasting machine through the dust collector. Too long dust removal pipe will increase the loss of air volume, resulting in insufficient negative pressure in the dust removal pipe and affecting the dust removal effect. The dust removal tube cannot be placed randomly during work. It is found through experiments that the dust removal effect is best when the dust removal tube is arranged in a bow shape.
With reference 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 collector, it is also affected by many other factors. In actual work, we need to combine many factors, consider all aspects, and appropriately adjust individual factors, so that the entire cycle of the road shot blasting machine can be realized smoothly and achieve the desired effect. The factors summarized by our company have certain guiding significance for the theoretical research and experiment of the dust removal device, and also have a certain reference value for the research on the polishing effect and polishing efficiency of the shot blasting machine. In addition to the improved dust removal device, it is also helpful to increase the service life of the road shot blasting machine.
