The invention belongs to the technical field of dust control of pulp shooting machines, and relates to a micro-negative pressure dust control device and method for a pulp shooting machine. An electric control valve is opened through a controller, and an air supply pipeline provides compressed air for an air ejector to generate negative pressure so as to suck dust in a dust control cover; in the suction treatment process, a negative pressure transmitter in the dust control cover monitors the negative pressure in the dust control cover in real time; and when the negative pressure mode in a dust collecting cover changes, a control box controls the electric control valve or a pressure flow monitoring and adjusting device of the air supply pipeline to adjust the negative pressure in the dust collecting cover, and the optimal dust suction negative pressure state is guaranteed. The concentration of dust generated in the operation process of the pulp shooting machine can be effectively reduced, the optimal dust suction negative pressure state is kept in the dust control cover all the time, normal use of the pulp shooting machine is not affected, and field use is easy and convenient.
Description
technical field [0001] The invention belongs to the technical field of spraying machine dust control, and relates to a micro-negative pressure dust control device and method for a spraying machine. Background technique [0002] During the working process of the shotcrete machine, dust will be ejected from the gaps in the fuselage. In order to control the ejected dust-laden airflow, a dust control cover is designed to wrap the fuselage, and a certain negative pressure environment is conducive to the extraction of dust-laden airflow. Purification treatment, but because the airflow ejected from the fuselage gap will affect the flow field in the dust control cover, it is necessary to control and adjust the negative pressure in the dust control cover. Contents of the invention [0003] In view of this, the object of the present invention is to provide a micro-negative pressure dust control device and method for a shotcrete machine to solve the problem of serious dust diffusion ...
