Lime milk conveying method and device

Abstract

The invention provides a lime milk conveying method and device, and the method comprises the steps: installing a conveying main pipeline according to the position of each user point, enabling the conveying main pipeline to pass through all user points, enabling each user point to be connected with the conveying main pipeline through a using point pipeline, and installing an automatic switch valve on each using point pipeline; the feeding end and the discharging end of a conveying main pipeline are connected with a lime milk outlet and a lime milk inlet of a preset lime milk storage tank respectively, so that the lime milk is circularly conveyed between the conveying main pipeline and the preset lime milk storage tank, and a lime milk circulating conveying device is obtained; a conveying branch pipeline is arranged between a lime milk outlet of the lime milk circulating conveying device and a conveying main pipeline, and a variable-frequency conveying pump is arranged on the conveying branch pipeline to adjust the flow of lime milk in the conveying main pipeline. The problems that in the long-distance lime milk conveying process in the prior art, lime milk is prone to curing, washing and overhauling are needed, labor intensity is high, the working procedure is complex, and efficiency is low can be solved.

Description

technical field [0001] The invention relates to the technical field of milk of lime transportation, and more specifically, to a method and device for milk of lime transportation. Background technique [0002] As a cheap industrial alkali, milk of lime is widely used in the neutralization process of various smelters. Lime milk preparation is usually set up in an independent workshop, and lime milk use points are usually distributed in various workshops in the factory area. Under normal circumstances, milk of lime needs to be transported to various user points through the comprehensive pipeline network in the plant area, so the transportation of milk of lime often has the characteristics of long pipeline transportation distance and complicated pipelines. In addition, milk of lime slurry is often relatively viscous and easy to solidify. In addition, there are many points of use in the factory area, which are often used intermittently, and the flow rate changes greatly, which b...
