Abstract

The invention discloses a novel intelligent wind locking device for a vertical mill. The novel intelligent wind locking device comprises a wind locking body, an electric control mechanism and a hopper arranged at the upper part of the wind locking body, wherein stirring rollers are arranged in the wind locking body and driven by a variable frequency motor; the variable frequency motor is controlled by the electric control mechanism; a high-order level gage, a low-order level gage and a level gage receiver are arranged on the outer wall of the hopper; the level gage receiver acquires information from both the high-order level gage and the low-order level gage through corresponding settings; the electric control mechanism receives the information of the level gage receiver; and the discharging speed is changed through changing the speed of the variable frequency motor, so that the level in the hopper is always kept at a certain height, and wind blockage is formed during feeding through a feed opening. Compared with the prior art, the novel intelligent wind locking device is simple in structure and reasonable in design, can realize automatic control through the electric control mechanism, reduces air intake as much as possible while guaranteeing the normal feeding quantity of the vertical mill, and achieves wind locking and blocking functions.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a novel vertical mill intelligent air lock device. Background technique [0002] The vertical mill air lock system is an important project for energy saving and consumption reduction of the entire vertical mill equipment, and it is also a key link in the assessment of energy consumption per ton output. In the building material industry, especially in the cement production industry, the cement vertical mill air lock mechanism is widely used. Among them, three air lock valves are particularly common. As the discharge structure of air-swept mill, the vertical mill needs to work under negative pressure. Therefore, the three air lock valves must ensure the normal feeding volume of the vertical mill and at the same time reduce the system air leakage as much as possible to realize the air lock function. However, due to the harsh working environment of the feed port of the v...
