Precise temperature control system of low-temperature chain grate machine for copper tailings and control method of precise temperature control system

Abstract

The invention discloses a precise temperature control system of a low-temperature chain grate machine for copper tailings and a control method of the precise temperature control system. The control system comprises a chain grate machine body, a main fan, a first circulating fan, a second circulating fan, a first main circuit and a second main circuit; the chain grate machine body is divided into 24 segments in the length direction, the first segment of the chain grate machine body is provided with a fuel gas inlet, and the 24 segment of the chain grate machine body is provided with a fuelgas outlet; the main fan is connected with the fuel gas inlet of the first segment of the chain grate machine body through a pipeline; the left side and the right side of each segment of the chain grate machine body are provided with branch circuits respectively, and each branch circuit is provided with an electric control valve; all the branch circuits on the left side of the chain grate machinebody are converged to the first main circuit, and all the branch circuits on the right side of the chain grate machine body are converged to the second main circuit; and the first circulating fan is located on the first main circuit, and the second circulating fan is located on the second main circuit. According to the precise temperature control system of the low-temperature chain grate machine for the copper tailings and the control method of the precise temperature control system, the temperature of the low-temperature chain grate machine for the copper tailings can be precisely and automatically controlled, operation is easy, convenient, reasonable, humanized, automatic and precise, the site production requirements can be completely met, manpower resources are saved, and unmanned production can be achieved.

Description

technical field [0001] The invention relates to a precise temperature control system of a low-temperature chain grate for copper tailings and a control method thereof, belonging to the field of temperature control of the chain grate. Background technique [0002] Copper tailings are nickel-copper smelting slag. With the continuous development of modern industrial technology, there are more and more copper tailings in the non-ferrous industry. Copper tailings treatment has become an important factor in the production process of enterprises. Proper treatment of copper tailings can not only reduce slag The land occupation and environmental protection problems caused by stockpiling can also turn waste into treasure. The low-temperature chain grate is an important link in the process of copper tailings treatment. After the copper tailings are processed as raw materials, they form pellets and enter the low-temperature chain grate for screening and heating. Among them, the control ...
