Calcium hydroxide powder feeding device

Abstract

The invention discloses a calcium hydroxide powder feeding device. The calcium hydroxide powder feeding device comprises a first conveying part, a second conveying part and a buffering bin. The two ends of the buffering bin are connected with the first conveying part and the second conveying part correspondingly. One end of the first conveying particularly is connected with a feed bin. One end ofthe second conveying particularly is connected with a neutralization tank. The first conveying particularly comprises a first shell arranged horizontally and a first auger arranged in the first shell.The second conveying particularly comprises a second shell arranged obliquely and a second auger arranged in the second shell. The first shell and the second shell each comprise a hard shell layer and a soft shell layer, and the soft shell layer is arranged on the inner side of the hard shell layer in a sleeved mode. Each soft shell layer is provided with heat dissipation channels. The two ends of each heat dissipation channel are provided with an air inlet and an air outlet correspondingly. The air inlets are connected with an air charging device. The calcium hydroxide powder feeding deviceprovided by the invention effectively prevents materials from being hardened on the wall of a pipeline and is good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of calcium propionate production equipment, in particular to a calcium hydroxide powder feeding device. Background technique [0002] In the production process of calcium propionate, it is necessary to add calcium hydroxide in bags to the neutralization tank for chemical reaction. In the prior art, calcium hydroxide powder is mainly added to the neutralization tank manually or by feeding equipment, but the following problems generally exist: First of all, the calcium hydroxide powder in the raw material tank is transferred to the neutralization tank through the inclined auger. When there is a power failure, a large amount of material on the auger is likely to gather at the low place where the raw material tank and the auger meet to cause blockage; Secondly, the auger generates a lot of heat in the process of conveying materials. On the one hand, the superheated calcium hydroxide powder is put into the neutra...

[0002] In the production process of calcium propionate, it is necessary to add calcium hydroxide in bags to the neutralization tank for chemical reaction. In the prior art, calcium hydroxide powder is mainly added to the neutralization tank manually or by feeding equipment, but the following problems generally exist: First of all, the calcium hydroxide powder in the raw material tank is transferred to the neutralization tank through the inclined auger. When there is a power failure, a large amount of material on the auger is likely to gather at the low place where the raw material tank and the auger meet to cause blockage; Secondly, the auger generates a lot of heat in the process of conveying materials. On the one hand, the superheated calcium hydroxide powder is put into the neutralization tank for chemical reaction, which will easily affect the reaction effect. On the other hand, the calcium hydroxide powder is easy to Compaction on the shell of the wrapping conveyor belt, which affects the transmission of calcium hydroxide powder
