Embodiment Construction

[0056] Belt conveyor is a typical material conveyor, which is commonly used in various production processes. For example, the sintering process of iron and steel enterprises. The sintering process of iron and steel enterprises involves batching, mixing, ignition, sintering and cooling. The raw materials used include iron-containing materials, fluxes and solid fuels. Usually, solid fuel coke powder for batching needs to be produced through the following process: Coarse coke trough—roller crushing—relay trough—four roll crushing—powder coke trough—batching, and the materials in the trough are generally transported to the next stage by a belt conveyor. One process, for example, uses a belt conveyor to transport the coke powder in the powder coke tank to the batching process.

[0057] For a long time, it has been generally accepted that the most suitable sintered fuel particle size is 0.5 mm to 3 mm. If the particle size is too large, the combustion speed will be slow, the combu...

Abstract

The application discloses a belt conveyor transport material length control sampling device, sampling control method and system, wherein the length control sampling device includes a rotating drive mechanism, a sampling body, a sampling device, a frame and a transmission assembly; the rotating drive mechanism makes the sampling body Rotate from the high position to the low position, contact with the material transported by the belt conveyor, and scrape the material into the sampling device to realize sampling. The transmission components and gears can adjust the length of the sampling body to control the sampling volume. The sampling control method of this application controls the length and rotational speed of the sampling body of the sampling device according to the current operating speed of the belt conveyor, the material transportation flow and the pre-generated control model, thereby controlling the sampling volume and avoiding empty samples. At the same time, the sampling is timely, accurate, and efficient. The sample is representative.

Description

technical field [0001] The present application relates to the field of belt conveyor material transportation, in particular to a belt conveyor material length control sampling device, sampling control method and system. Background technique [0002] The sintering production process of iron and steel enterprises includes batching, mixing, ignition, sintering and cooling. The raw materials used include iron-containing materials, fluxes and solid fuels. In actual production, the particle size composition and moisture content of the solid fuel used for batching are important factors affecting the sintering behavior. [0003] For a long time, it has been generally accepted that the most suitable particle size of sintered fuel is 0.5mm-3mm. If the particle size is too large, the combustion speed will be slow, the combustion zone will become wider, the maximum sintering temperature will decrease, the gas permeability will become poor during the sintering process, and the vertical ...
