At present, the random dust dispersion of bag cement loading machine has been a national technical problem puzzling the cement profession to the hygienic standard of respirable cement dust in the air of workshop. This requests the supplier according to technical conditions of cement bag occupation cement loading machine field operations, arranging skills innovation, meticulous research and development bag cement loading machine dust removal equipment, to solve the problems in the dust bag cement loading machine. This paper introduces the new concept and new skill analysis of dust collection planning for bag cement loader and the technical parameters of dust catcher.
1、除尘规划的新理念与新技能
1, the new concept and new skills of dust removal planning
袋水泥装车机的除尘设备规划应遵循以下准则：
The planning of dust removal equipment for bag cement loader shall follow the following guidelines:
(1)袋水泥装车机作业时对无序分散扬尘要操控在必定的空间层面上，可移动式吸尘罩在满意搜集扬尘，避免扬尘进一步分散到空气中的一起，还要确保扬尘的搜集只能操控在操作工人腰部以下，加强操控扬尘的空间层面，给操作工人发明一个杰出健康的作业呼吸环境空间。
(1) during the operation of bag cement loading machine to control the disorderly scattered dust in the space level must be on the removable dust cover to collect dust in the dust, to avoid further dispersed into the air together, but also to ensure that the collected dust can only operate in operation workers to strengthen the level of waist, space control dust, to workers invented a healthy working environment breathing space outstanding.
(2)水泥扬尘属冷态粉尘空气气体，而冷态空气再加上水泥粉尘的分散混合，比重密度增大，依据水泥粉尘空气的特殊性，请求吸尘罩规划时要有足够大的负压，请求吸尘罩口间隔尘源800mm之间。
(2) the cement dust is cold gas and dust in the air, the cold air plus cement dust dispersion mixing proportion, density increases, according to the particularity of cement dust in the air, dust cover request planning to have a large enough negative pressure between the suction hood mouth dust source request interval 800mm.
(3)水泥粉尘吸尘罩规划要有必定的覆盖面，要力求适用于多种装袋水泥的运输车型，并能依据车型进行自动调整。
(3) cement dust hood planning must have certain coverage, we should strive to apply to a variety of bagging cement transport models, and can be adjusted automatically according to type.
?
.
(4)袋水泥装车机的吸尘和输尘体系要能满意出产技术请求，要随出产技术前后，上下移动，最主要的还要满意安全出产的请求。
(4) the dust absorption and dust handling system of the bag cement loader should be satisfied with the technical requirements of production, and should be moved up and down with the production technology. The most important thing is to satisfy the request of safe production.
