Tank car.
Background technology
Bulk cement tank car be for shipping bulk cement, and by ground auxiliary facility realize long-distance transportation,
A kind of industrial railway vehicle of automated handling.At present, domestic bulk cement tank car is mainly horizontal type cement tank car, its
Design is main to employ fluidization technology, during discharging, compressed air is sent into lower chamber in tank using pneumatic conveying principle, relied on
Fluid bed makes granular cement fluidization, recycle tank body inside and outside differential pressure by cement via Pipeline transport into material storehouse.It is domestic
The fluidization system of outer horizontal bulk cement tank car mainly has fluidized bed plant structure built in tank body and tank body to be filled with fluid bed
Two kinds of integral structure is put, wherein fluidized bed plant mainly has overall two kinds of canvas structure and corrugated tube type canvas structure.
At present, China U61 series, U70 types bulk cement carrier and U80 types bulk cement carrier use sandwich-type built in tank body to fluidize
The structure of bed apparatus, the structure generally using cylindrical tube and with insertion central sill chassis, maintain tank car rigidity,
The advantages that intensity is big, and longitudinal loading transmission capacity is strong, while the connected mode of inheriting tradition tank body of tank car and chassis, structure
Reliably, packaging technology is ripe.Its shortcoming be from it is great, center of gravity is high because increase fluid bed inclination angle with improve dischargeable capacity, reduce
Contradiction can be produced between center of gravity, reduction residual volume, if increase fluid bed inclination angle increases the dischargeable capacity reduced in tank body and center of gravity
Height, if fluid bed inclination angle is too small and influences cement fluid effect, reduces rate of discharging and increases residual volume.
U80 (H) type bulk cement carrier fluidization system uses the fluid bed with vehicle tank body for integral type structure.This fluid bed
It is to be close to the laying of tank body lower part inwall by many flexible pipes to form.The structure be able to can reduce more sufficiently using space in tank
Vehicle's center of gravity, add stability during vehicle high-speed operation.Its shortcoming is to employ tilted conical tank body, and tilted conical tank body is general
Used with the pillow pulling respective outer side edges without central sill, it transmits the ability of longitudinal loading and declined, and the tank body taper of use is held more greatly
