Embodiment 1

[0033] A production process for reducing cross-contamination of bagged mortar, the process flow and process layout are shown in figure 1 , figure 2 shown, including the following steps:

[0034] Lifting and storage of raw materials: Various materials such as cementitious materials, aggregates, fillers, admixtures, etc. are mechanically lifted or pneumatically lifted into the raw material storage warehouse at the top of the production line, and stored for use.

[0035] Metering and conveying: Various materials in the raw material storage bin enter their own weighing scales successively through the supporting measuring screw, and measure to the formula setting value. The admixture scale should not directly enter the mixer, so as to enter the large scale of the gelling material and filler, It is advisable to enter the mixer together, so as to ensure the metering accuracy of the admixture.

[0036] Mixing and homogenization: various materials in the weighing scale enter the mix...

Abstract

The invention discloses a production process for reducing cross contamination of bagged mortar. The production process comprises the following steps of (1) a lifting and storing procedure; (2) a metering and conveying procedure; (3) a mixing procedure; (4) a material separation procedure; (6) a control system; and (7) a dust removal system. According to the production process, the problem of quality fluctuation caused by cross contamination when different varieties of bagged materials are produced on the same line can be solved; the problems that during collinear production of different varieties of products, material waste is caused by replacement of product flushing equipment, and the workload of waste digestion treatment is increased are solved; and the problems that when the products of different varieties are subjected to collinear production, the production efficiency is reduced due to replacement of the product flushing equipment, and accordingly productivity exertion is affected are solved.

Description

technical field [0001] The invention relates to the technical field of dry powder mortar production, in particular to a production process for reducing cross contamination of bagged mortar. Background technique [0002] Dry powder mortar is a dry granular material. When different types of mortar products are produced in the same production line, if they are not cleaned, cross-contamination will be formed in the secondary lifting bucket elevator, mixer, and packaging warehouse, which will affect product quality. For example, cross-contamination of lightweight aggregates caused by products with lightweight aggregates to other products, cross-contamination between products with flow properties and products without flow properties, cross-contamination between products of different colors, etc., to control product quality bring difficulty. [0003] At present, the common ways to solve cross-contamination are as follows: When replacing the production product, first use a selected...
