Abstract

The invention relates to a rotary kiln production method and equipment for a bleaching powder product. The production method is characterized by comprising the following steps: pouring slaked lime into a rotary kiln with inclination during a chlorination process of slaked lime and chlorine, continuously winnowing and spreading slaked lime through a plurality of winnowing plates arranged in the rotary kiln and capable of rotating along with the rotary kiln so that the slaked lime and refluent chlorine are fully contacted and chlorinated, wherein the adopted rotary kiln is a cylinder with two closed ends and can axially rotate, a feed inlet is formed in one end of the rotary kiln, a discharge outlet and a chlorine inflation inlet are formed in the other end of the rotary kiln, the cylinder has a gradient as a whole, and a plurality of L-shaped winnowing plates which are axially arranged and have bends are evenly arranged on the inner wall of the cylinder. The defects and deficiencies of the traditional central screw chlorination technology can be fundamentally overcome, the technological process and the adopted equipment are simpler, the chlorination effect is better, the products have higher quality and are energy-saving and environment-friendly, and the rejection rate of products and the production, installation, and maintenance costs of equipment can be greatly lowered.

Description

technical field

[0001] The invention relates to the production of bleaching powder, in particular to a production method of bleaching powder products, that is, a rotary kiln production method and the equipment used therein. Background technique

[0002] At present, the production method of known bleaching powder product is: slaked lime (calcium hydroxide) is sent in the bleaching powder machine by conveyor, becomes bleaching powder finished product after contacting chlorination with chlorine countercurrent in the bleaching powder machine. The chlorination process of this method adopts central spiral stirring chlorination: the powder bleaching machine is composed of four or five mixing drums 1 fixedly arranged and connected in order from top to bottom, and the central shaft 2 of each mixing drum is equipped with multiple pieces Stirring screw blade 3 (as attached figure 1 As shown), the motor drives the central shaft and rotates the spiral blades to stir the slaked lime to c...
