In the production process of shaft furnace production, the metallurgical lime shaft furnace body is generally divided into three parts: the pre-tropical roasting zone cooling zone from top to bottom. The mixed limestone and fuel are sent to the top of the shaft furnace by the loading trolley, and enter the pre-tropical zone of the furnace body through the cloth system. Gradually move downwards as the production progresses, and then pass through the calcining belt and the cooling belt, and the ash is discharged. The system is discharged outside the furnace as finished lime. The combustion air is sent from the bottom of the furnace to the furnace body by the blower and gradually moves upwards, and then passes through the furnace cooling belt roasting belt and the pre-tropical zone, and is discharged from the top of the furnace in the form of exhaust gas. In the pre-tropical zone, the cold material of the human furnace exchanges heat with the rising hot gas, the material is heated, the gas is cooled in the calcination zone, and the gradually heated fuel reacts with the rising hot air to release a large amount of heat, and the limestone absorbs The heat is decomposed and reacted to form lime in the cooling zone, and the finished lime with a certain heat is moved downward to exchange heat with the cold air. The lime is cooled until it is discharged from the furnace body, and the cold air is heated and continues to move up. The entire production process is automated by computer control. The two-stage computer control system two-stage computer control system is the refinement and improvement of the original automatic control system of the Anyang Steel Lime Shaft Furnace, so that every link of the production process can be carried out in an orderly manner according to the preset scheme, and the signal transmission is further systematic. It reduces or even eliminates the mis-delivery of the signal. Its design and configuration features are as follows: System hardware configuration The upper computer system uses the Advantech one industrial computer, the machine adopts the bus structure, interpolates two data acquisition boards, and the temperature The conversion module and the pressure flow conversion module are inserted on a carrier board outside the host, and the carrier board is connected to the data acquisition board through a communication cable to transmit the live analog signal to the upper computer. The number of system switching points is 16 analog, the switch input template receives the main control room console and the field switch signal, the switch output template is controlled by the relay control device, and the analog output template is controlled by controlling the inverter. The shifting device is running. The system configuration is programmed in Siemens language and modularized. The lower machine control system can be divided into three parts: the partial furnace part and the ash part. (Finish)
T Series Pallet Wrapping Machine
Turntable wrappers are mainly used for the packaging of big cargo or pallet that needs to be transport or stored. The pallet load/cargo is loaded onto the rotating turntable, which carries the pallet/cargo rotates so as to wrap the goods around. It is widely used in glass products, hardware, electronic appliances, paper-making, ceramics, chemicals, food & beverages, building materials and so on. This type of packaging is high in packaging efficiency, anti-dust, anti-moisture and reduce the labor cost & material cost. Customized machines available.
