为了提高吹砂作业自动化程度和工作效率,减轻工人劳动强度,改善通风除尘效能和工人劳动条件,我厂曾本着大胆尝试的态度,改变了以往吹吵除尘的一般设计方法,把气力输送原理运用到吹吵设备和通风除尘系统上来,设计试制出一种气力输送自动回砂除尘装置(图1),取的了较好的效果。 In order to improve the degree of automation and working efficiency of blowing sand, reduce the labor intensity of workers and improve the ventilation and dust removal efficiency and working conditions of workers, our factory has in a bold attempt to change the general design method of blowing noise in the past, the principle of pneumatic conveying Used to blew the equipment and ventilation dust removal system, the trial design and manufacture of a pneumatic conveying automatic dust removal device (Figure 1), and took a better effect.
