Body and ejecting device, mainly include hopper, hopper, reductor and rotor block assembly on rotor-type concrete sprayer body,
Upper and lower excessive gas port is typically offered on mixed mud spraying machine body, concrete material is easily discharged to air from upper and lower excessive gas port
In；Its circumference can spill many whitewashing raw materials after the friction plate abrasion of rotor block, and can be caused after friction plate abrasion anti-to hopper
Wind, the whitewashing raw material impacted in hopper, whitewashing is set to form dust discharge；Need to add water in shower nozzle during dry spray, due to current spray
Water and cement and sand material undercompounding in mouth structure, also cause to produce a large amount of dust from nozzle exit during injection, and greatly
The compound resilience of amount, it is medium to air to easily cause great waste of material.It is big that the above factor results in cement dust
It is discharged into air to amount, seriously pollutes working environment, not only endanger the health of field operation worker, can also further release
It is put into air, aggravates the pollution of air, and harm of the cement dust to people is bigger, and suction for a long time can cause serious silicon
The serious occupational disease such as tuberculosis, can not be effected a radical cure.Therefore, for dry pressure spray process and equipment feature, serious analysis dust emission source,
Improvement is made to existing dry spraying equipment, it is necessary to a kind of concrete sprayer that can effectively reduce spraying machine dust emission.
