Problems solved by technology

[0006] In view of the large error between the data obtained by quantitative feeding equipment and the real data in the current mixing process, which easily leads to the problem of low quality or even scrapping of the produced mixture, the present invention utilizes the principle of measurement traceability, and establishes reference values ​​and error statistics and The recursive compensation method continuously ensures that the execution process is close to the planning process, so as to achieve the purpose of improving the accuracy of the entire mixing system

Embodiment 1

[0033] A kind of mixing production process control method of the present embodiment, its steps are:

[0034] Step 1. Obtain the amount of slotting a, the amount of material in the initial bin m, the amount of material at the end of the cycle n, the amount of batching c, the batching rate r, and the theoretical batching rate r within an adjustment period t during the mixing process 0 :

[0035] Among them, the amount of slotting a is measured by the slotting scale at the feed inlet of the storage bin; the initial amount of material in the bin m and the amount of material at the end of the cycle n are measured by the hopper scale; the amount of ingredients c is measured by the quantitative feeding equipment ; Batching rate r=batching amount c / period t; The theoretical batching rate r 0 It is the planned total amount / planned batching time.

[0036] Step 2. Determine the relative error of the dosing equipment and the hopper scale, and calculate the absolute error within the mixi...

Abstract

The invention discloses a method for controlling a mixing production process, which belongs to the technical field of ore blending. The method of the present invention comprises the following steps: step 1, obtaining the slotting amount a, the initial material volume m in the warehouse, the cycle-ending material volume n, the batching amount c, the batching rate r and the theoretical Batching rate r 0 Step 2, determine the relative error of the quantitative feeding equipment and the hopper scale, and calculate the absolute error in the mixing cycle; Step 3, introduce the measurement data of the slotting scale, and compensate and correct the error of the quantitative feeding equipment; Step 4, Obtain correction data to adjust the feeding process of the dosing equipment every cycle. The invention introduces the metering data of the slotting scale to correct the error of the data collected by the quantitative feeding equipment, so that the obtained feeding amount is closer to the real value, and the batching accuracy of the mixing system is improved.

Description

technical field [0001] The invention relates to the technical field of ore blending, and more specifically, relates to a method for controlling a mixing production process. Background technique [0002] The mixing production process is generally equipped with three parts: feeding and adding tank system, intermediate storage bin, and batching system. Each part is equipped with corresponding metering equipment. At the same time, a static hopper scale is installed at the position of the intermediate storage bin, which is used to weigh the material balance in the intermediate storage bin. The batching system is equipped with quantitative feeding equipment, and a quantitative feeding scale is set on it to measure the amount of material distributed to the mixing tank. [0003] During the mixing process, it is necessary to control the proportion of the produced mixture by controlling the amount of material delivered to the mixing tank. Usually, when calculating the ratio, the spe...
