Description

Continuous mixer's shedding mechanism

Technical Field

The utility model belongs to the technical field of mine filling equipment, and particularly relates to a discharging mechanism of a continuous stirrer.

Background

The continuous mixer blanking in the existing filling industry mainly adopts a mode of perforating the bottom of a tank body and controlling an electric pinch valve, and has the following main problems: the blanking pipe section is overlong, and is easy to accumulate and even block the blanking pipe. The response speed of the electric pinch valve is too slow, the time required for full opening or full closing is too long (basically more than 1 minute is required, the larger the valve size is, the longer the time is required), and the unstable upstream feed is extremely easy to cause the top of the tank body of the stirrer to be overflowed; too slow a response speed cannot meet the requirements of electric automation control.

In addition, the continuous mixer material level detection of the existing filling industry mainly detects through visual observation or radar material level gauge, and the radar material level gauge is mainly installed at a cover plate above a tank body, so that the following problems exist: the visual observation needs to be controlled manually, and the labor intensity is high. The stirring blades which rotate continuously are fully distributed in the tank body, the normal working liquid level surface of the stirrer is arranged at the stirring central shaft, and the radar level gauge above the tank body cannot detect the real working liquid level surface at all, so that the stirrer cannot participate in control. If a real working liquid level surface is detected, a part of stirring blades are needed to be removed, and the stirring effect is influenced; the other mode is to stretch the tank body, a section of gap without stirring blades is reserved at the end part of the tank body, and the radar level gauge is arranged at the position, but the slurry is gradually hardened and solidified at the position due to no stirring effect at the position, so that the cleaning is difficult.
