Embodiment 1

[0025] An embodiment provided by the present invention: an automatic control system for a stacker and reclaimer. The stacker performs automatic control according to the type of incoming raw materials, the status of each stockpile in the stockyard with or without material, and the stockpile area where it is located. Pile adjustment and automatic material distribution, the automatic control of the stacker switching from one stacking area to another stacking area after completing the stacking operation in one stacking area, the slow speed of the stacking belt conveyor support frame during the stacking operation of the stacker And fast lifting adjustment, start and stop of the stacking belt conveyor, left and right walking of the cart, and encountering the working limit and side radar reflection signals in the working pile area and delaying for a period of time, it becomes reverse walking, It goes round and round until it receives the stop command issued by the DCS system, and the ...

Embodiment 2

[0028] An embodiment provided by the present invention: an automatic control system for a stacker and reclaimer, the raw coal reclaimer automatically stops when the grinding head bin is full and automatically starts to reclaim when the bin is empty, and the raw coal reclaimer completes reclaiming in a stacking area The automatic control of switching from one stacking area to another stacking area after operation, the start and stop of scraper machine, the start of material rake and the slow walking of the cart in the direction of material reclaiming during the reclaiming operation of the raw coal reclaimer Start and stop, follow the start and stop of the power cable reel.

[0029] Replace the slot switch with a very high failure rate in the three areas of the raw coal storage yard (including the stacking area) with a travel switch with a very low failure rate, and combine the corresponding program compiled in the PLC to realize the raw coal The program division of the stacking...

Embodiment 3

[0031] An embodiment provided by the present invention: an automatic control system for a stacker-reclaimer. The auxiliary material reclaimer automatically starts and stops the conveying belt conveyor, automatically adjusts the pile, and automatically Reclaiming, the auxiliary material reclaimer is automatically controlled from one stacking area to another stacking area after the auxiliary material reclaimer completes the reclaiming operation, and the auxiliary material reclaimer is in the process of retrieving materials. The slow and fast lifting adjustment of the scraper hoist determined by the size, the start of the scraper triggered by the radar reflection signal vertically irradiating the material surface and the stop issued by the DCS system, the left and right slow travel of the cart And after encountering the working limit and side radar reflection signals in the working pile area, after a delay for a period of time, it becomes reverse walking, and it goes round and rou...

Abstract

The invention discloses an automatic control system of a stacker- taking machine, the stacker-taking machine is composed of a stacker, a raw coal taking machine and an auxiliary material taking machine, wherein the stacker, the raw coal taking machine and the auxiliary material taking machine are provided with a PLC (programmable logic controller) in a field control cabinet; piling areas of raw coal and auxiliary material storage yards are divided, and partition signal devices are mounted, so that the partition signal devices can accurately track the piling areas where the stacker, the raw coal taking machine and the auxiliary material taking machine are located in real time and accurately send piling area signals to a DCS; a PLC (programmable logic controller) in the field control cabinet is provided with a protection program, an interlocking function in a DCS (distributed control system) and a DCS protection function; and anti-collision radar detectors are arranged on the stacker, the raw coal taking machine and the auxiliary material taking machine. The full-automatic control system has the advantages that on-site manual operation of the stacker, the raw coal taking machine and the auxiliary material taking machine is changed into full-automatic control, the labor cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to an automatic control system for a stacker-reclaimer. Background technique [0002] Cement is a powdery water-hardening inorganic gelling material. It becomes a slurry after being stirred with water. It can be hardened in air or in water, and can firmly bind sand, stone and other materials together. In the early years the mixture of lime and volcanic ash is very similar to lime pozzolanic cement, use it to glue concrete which made of crushed stone. After hardening, the cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0003] General-purpose cement: cement commonly used in general civil construction projects. General-purpose cement mainly refers to: the six types of cement sp...
