Lime pretreatment storage tank

Abstract

The invention discloses a lime pretreatment storage tank, and belongs to the technical field of treatment tanks. According to the technical key points, the lime pretreatment storage tank comprises a first tank body and a second tank body which are arranged up and down, the first tank body and the second tank body are connected through a first pipeline, a stirring mechanism used for scattering blocky lime is arranged on the first pipeline, and the second tank body further communicates with the first tank body through a second pipeline; and a vacuum pump capable of extracting the lime of the second tank body into the first tank body is arranged on the second pipeline, an air blowing pipeline capable of allowing inert gas to be blown thereinto is arranged on the side wall of the second tank body, and the second tank body is provided with a feeding port with an electric control valve and a discharging port. The lime pretreatment storage tank has the characteristics that the lime can be stored for a long time, the lime can be prevented from going bad, and the utilization rate of the lime can be improved.

Description

technical field [0001] The invention relates to a treatment tank, more specifically, to a lime pretreatment storage tank. Background technique [0002] At present, the lime used to make cement and concrete is mainly composed of calcium oxide, but because calcium oxide is prone to react with water, the lime will deteriorate during storage, and in the lime mixture, calcium silicate, For substances such as calcium aluminate, this chemical reaction is irreversible. Therefore, before the lime needs to be used, it is necessary to reduce the contact with the air when storing the lime. At the same time, the lime is in powder form, and it is easy to be compacted into lumps if it is piled up for a long time, which is inconvenient for transportation. Existing storage tanks can only store lime no more than two days, especially in the rainy weather in the south, more than one day. Otherwise, the lime will deteriorate and reduce the content of calcium oxide, thereby reducing the utiliza...

Problems solved by technology

[0002] At present, the lime used to make cement and concrete is mainly composed of calcium oxide, but because calcium oxide is prone to react with water, the lime will deteriorate during storage, and in the lime mixture, calcium silicate, Calcium aluminate and other substances, this chemical reaction is irreversible

Therefore, before the lime needs to be used, it is necessary to reduce the contact with the air when storing the lime. At the same time, the lime is in the form of powder, and it is easy to be compacted into a block if it is piled up for a long time, which is inconvenient for transportation.

Existing storage tanks can only store lime for no more than two days, especially in the rainy weather in the south, let alone one day

Otherwise, the lime will deteriorate and reduce the content of calcium oxide, thereby reducing the utilization rate of lime
