Description

Technical Field

[0001] The utility model relates to the technical field of slag mill dust collection and mill stop prevention, in particular to a slag mill dust collection device. Background Art

[0002] When producing cement, the most harmful and serious thing is cement dust, so the dust removal process is an important part of the cement production process. When some parts in the dust removal process are damaged, it often needs to stop production for maintenance and replacement due to the impact on dust removal efficiency, which seriously affects production efficiency.

[0003] The dust collecting device mainly includes solenoid valve, pulse valve, pulse controller, controller, air supply pipe, filter bag, ash hopper, filter bag frame, blowing pipe, etc. A cleaning device is usually designed inside the dust collecting device to clean the dust in the gas entering the box and collect the dust. When it is working, the blowing pipe sprays the gas in the air bag, thereby cleaning the dust filter bag. In order to reduce the impact force between the gas in the blowing pipe and the gas in the air inlet, a buffer pad is designed at the connection with the ground to protect the safety of the equipment, thereby reducing the impact force generated by the operation of the equipment. The opening and closing of the solenoid valve and the pulse valve can be precisely controlled by the controller and the pulse controller, and regular jetting is performed to ensure the cleaning effect of the equipment without causing waste caused by dust accumulation or short jetting intervals.

[0004] However, the pulse valve is the most important part of the dust collecting device and also the part with the largest loss during operation. Its quality and performance directly affect the working effect and service life of the dust removal equipment. Therefore, a suitable pulse valve is selected according to the specifications and parameters of the dust collector to ensure that the working pressure, flow rate and injection cycle of the pulse valve match the working conditions of the dust removal equipment. At the same time, the valve body and valve core are designed to adopt materials with good wear resistance, sealing and corrosion resistance to ensure the pressure and stability of the gas source. However, when the pulse valve fails, the mill needs to be stopped for maintenance, which makes it difficult for the dust removal equipment to operate normally. Therefore, a slag mill dust collection device is needed to solve the above problems. Utility Model Content
