Efficient lime slaking and deslagging device

Abstract

The invention discloses an efficient lime slaking and deslagging device. The efficient lime slaking and deslagging device comprises a tank body, wherein the tank body is fixedly mounted on a support;the top of the tank body is provided with a stirring device, a lime feeding hole and an exhaust hole; the stirring device is positioned at the center of the tank body; the exhaust port is positioned in one side far away from the lime feeding hole; a water cooling wall is arranged on the side wall of the tank body; a water inlet connected with an external water source is formed in the lower part ofthe water cooling wall; a water outlet communicated with the interior of the tank body is formed in the upper portion of the water cooling wall; a slurry overflowing opening is formed in the upper portion of the side wall, away from the lime feeding hole, of the tank body; the water outlet is higher than the slurry overflowing opening; a filter screen is arranged on the slurry feeding side of theslurry overflowing opening and provided with a vibration motor; and a slag discharging opening is formed in the bottom of the tank body. The efficient lime slaking and deslagging device can prevent impurities and lime which does not react completely from caking and overflowing out of the tank body, guarantees discharging quality, realizes cooling in the tank body while providing water for a limeslaking reaction, and promotes forward progression of the lime slaking reaction.
