Embodiment Construction

[0017] The present invention will now be described in further detail.

[0018] Such as figure 1 The shown automatic water addition control device for pelletizing pellets includes a raw pellet belt, a video particle size analysis system, a drip tube, and an atomizing tube. The drip tube is provided with a drip tube regulating valve and a drip tube flowmeter. The atomizing tube is provided with an atomizing tube regulating valve and an atomizing tube flowmeter. The video particle size analysis system adopts STV7800 of Tianjin Sante. The video particle size analysis system includes a camera and an industrial control computer (also known as an industrial computer). The camera is installed above the raw ball belt, the camera is connected with the industrial control computer through the data transmission device, and the image signal is transmitted to the industrial control computer, and the industrial control computer is connected with the input end of the PLC, and the input end of ...

Abstract

The present invention relates to an automatic watering control device and method for pelletizing pellets, including a raw pellet belt, a video particle size analysis system, a drip pipe, and an atomizing tube. The video particle size analysis system includes a video camera and an industrial control computer. The video camera is installed on Above the raw ball belt, the camera is connected with the industrial control computer through the data transmission device, and the image signal is transmitted to the industrial control computer, and the industrial control computer is connected with the input end of the PLC. The present invention controls the whole process from the incoming iron powder, the ratio of additives to the granularity of green balls, not only can realize the automatic setting and adjustment of the total amount of water added; The water distribution is adjusted and controlled, which greatly improves the production rate of green pellets and reduces the energy consumption in the pellet roasting process.

Description

technical field [0001] The invention relates to the field of ironmaking production, in particular to a device and a method for controlling the dust concentration of a pellet belt conveyor transport and transfer system. Background technique [0002] At present, the water content of the raw pellets is detected through a contact detection device. Due to the large fluctuations in the real-time value of the detection, at the same time, only the total amount of water added can be detected, and the separate control of dripping water and atomized water cannot be realized. Only The total amount of water can be adjusted. Contents of the invention [0003] In order to overcome the above shortcomings, the present invention provides a pelletizing automatic water addition control device and method, which can realize the automatic setting and adjustment of the total amount of water added, and realize the adjustment and control of the distribution of water addition to dripping water and a...
