The problem that the dust removal effect of concrete mixer is weakened has gradually become one of the important problems of concrete mixer enterprises. Also become the concrete mixer R & D departments focus on research and waist to solve the problem.

混凝土搅拌机是专注于搅拌站生产基地，就其搅拌站的除尘效果减弱的问题 ，剖析混凝土搅拌机除尘效果越来微弱原因：

The concrete mixer is focused on the production base of mixing station. In view of the problem that the dust removal effect of the mixing station is weakened, the reasons why the dust removal effect of the concrete mixer is becoming weaker and weaker are analyzed

许多用户为了方便和节省成本，直接将搅拌主机的引风管接在除尘器集尘料斗的下方。

For convenience and cost saving, many users directly connect the induced draft pipe of the mixing machine to the bottom of the dust collecting hopper of the dust collector.

由于风机的吸力，脉冲吹落的灰尘无法沉降到底部并流向主机，使滤芯始终处于灰尘的包围之中，灰尘没有沉降的过程，大大降低了除尘器的工作效率。的方法是在集尘料斗底部安装一个蝶阀，除尘器工作时关闭，所有的引风管都接在集尘料斗侧面法兰上，为脉冲吹落的灰尘提供沉降的空间，避免滤芯的二次污染。

Due to the suction of the fan, the dust from the pulse can not settle to the bottom and flow to the host, so that the filter element is always surrounded by dust, and the dust does not settle, which greatly reduces the working efficiency of the dust collector. The solution is to install a butterfly valve at the bottom of the dust hopper, close the dust collector when it is working, and all the induced air pipes are connected to the flange on the side of the dust hopper to provide settling space for the dust blown down by pulse and avoid the secondary pollution of the filter element.

根据实际情况，每班或4～5个小时定期打开蝶阀清理出收集来的粉尘。也可以安装一个由混凝土站软件操作系统自动控制的气动蝶阀，定期打开，将粉尘排放到搅拌主机中，减轻劳动强度。

According to the actual situation, open the butterfly valve regularly every shift or 4-5 hours to clean up the collected dust. A pneumatic butterfly valve automatically controlled by the software operating system of the concrete station can also be installed, which can be opened regularly to discharge the dust into the mixing host to reduce the labor intensity.

综合上述，正确设计和合理选用除尘设备，不仅可以避免粉尘对大气的污染，同时也提高了混凝土搅拌机的整体性能。

Based on the above, the correct design and reasonable selection of dust removal equipment can not only avoid the air pollution caused by dust, but also improve the overall performance of concrete mixer.
