Vertical Preheater

  • Introduction of Vertical Preheater

    Vertical preheater is one of the main equipments of active limestone. The main function is to send limestone materials sent by the upper part to the preheater body, while using the emitted high temperature gas (1150 ) after calcination, preheat the materials to about 900 evenly. During the preheat process, 30% CaCO3 is decomposed in the preheater, then by the hydraulic pressure stick putting into the rotary kiln to calcinate. This kind of technology not only shortens the calcined time in the kiln, but also can obtain higher degree of activity of the lime. 

     

    Structure of Vertical Preheater

    Vertical preheater system mainly consists of six main parts.

    1, the upper feeding system: includes the upper hopper, the next material possession, the next feeding method and structure can guarantee to the pre-heater of the body feeding to achieve security when closed, so that the cold air from outside can not enter into the preheater , and feeding can make use of valve rod to achieve continuous or intermittent feeding.

    2,preheater body: it is to ensure that material preheated to 900 degrees Celsius of the most important part, it is by the warm room, hanging devices and brick lining (which does not belong to the scope of design and manufacturing equipment) and other parts. That part of the structure of most of metal structures, part of the material according to the need to use a heat-resistant steel, heat-resistant steel to 1100 degrees celsius in 1000 to work under high temperatures. In addition, the refractory bricks lining structure, novel design, sealing is good, can guarantee the material in pre-heater evenly and achieve pre-heating temperature preheating.

    3, pusher devices: mainly Tuitou, framework, and connecting rods and other parts of Tuitou using heat-resistant steel casting or welded together, can withstand high temperatures, using electronic control and hydraulic systems can be by putting the various hydraulic automatic control program to achieve sequential pusher.

    4, the hydraulic system: includes tanks, pumps, motors, solenoid valves, hydraulic tubing, etc., his main role is to control the pusher device to push the completion of material movement.

    5, bottom feeding room: The main include slide tube, feeding the main room, feeding slip mouth and so on, its main role is to import the materials after preheating rotary kiln calcination.

    6, Framework: It includes columns and ring beam and so on, the main role is to carry The upper part of the structure.

     

    Features of Vertical Preheater

    It is to ensure that material preheated to 900 degrees Celsius of the most important part, it is by the warm room, hanging devices and brick lining (which does not belong to the scope of design and manufacturing equipment) and other parts. That part of the structure of most of metal structures, part of the material according to the need to use a heat-resistant steel, heat-resistant steel to 1100 degrees celsius in 1000 to work under high temperatures. In addition, the refractory bricks lining structure, novel design, sealing is good, can guarantee the material in pre-heater evenly and achieve pre-heating temperature preheating.
