Description
Technical field
The utility model relates to railway bulk cement tanker, refers to particularly a kind of without interlayer railway bulk cement tank vehicle tank.
Background technology
Railway bulk cement tanker is for loading and transporting cement and realizing a kind of special purpose railway vehicle of long-distance transportation, automated handling by the supporting handling facilities in ground.Tank body is the key components of the accumulating of railway bulk cement tanker, handling material.Railway bulk cement tanker is different from general liquid tank car, because loaded materials and cement is a kind of powdered granule thing, the bulk density of different labels cement is larger, how at 1.0～1.6 tons/cubic meter, static angle of repose is 40～45 °, cause its flowing power relatively poor, must rely on certain technological means to be drawn off.What conventionally adopt is fluidization technology, therefore the tank structure of bulk cement tanker and technical parameter is had relatively high expectations.
The general bulk cement tanker that adopts fluidization technology, in its tank body, be provided with fluid bed, cement fully mixes with pressurized air on fluid bed, and its flowing power is strengthened greatly, form a kind of gas-solid mixture that is similar to fluid, under the drive of certain wind speed, flow out discharge port.After cement fluidity strengthens, the inclination angle of required fluid bed reduces greatly than aforesaid static angle of repose, when being not less than 8 °, can flow preferably, and this structurally is more conducive to reduce Iinvalid volume, improves the internal dimensions of the loading space of tank body.
Railway bulk cement tanker is after having experienced improvement for many years, its tank body is changed into single cylindrical horizontal tank body by three vertical structures arranged side by side the earliest, the reason of its change structure is as follows: the one, because horizontal tank body itself can transmit longitudinal force, thereby the simplification that can bring Undercarriage structure, alleviates deadweight; The 2nd, horizontal tank body length is easy to adjust, and can change as required stowage.But because the bottom of cylindrical horizontal tank body is vertical equity shape, solid, powdery material cannot draw off by gravity flow, so in tank body, need to arrange the fluidized-bed structure with certain inclination angle.As shown in Figure 1, the tank interior of existing railway bulk cement tanker has adopted a large amount of support D and landslide plate A in discharge port B, fluid bed C both sides, these are positioned at the landslide plate A of tank both sides and at tank, form twin-bucket structure with the fluid bed C that is longitudinally inverted V-shaped layout.Sideslip ramp A and horizontal plane angle are not less than 40～45 ° of the static angle of reposies of material conventionally, and fluid bed C and horizontal surface angle are generally 10～15 °.In discharge process, material slides to middle fluid bed C top along landslide, both sides plate A, after being positioned at material on fluid bed C and being fluidized under airflow function from bottom to top, flow in discharge port B place to lower part, at discharge port B place, enter discharge cone bucket, after fluidization, enter again Pneumatic conveying pipeline, by Pneumatic conveying pipeline, deliver to ground fabric tower.
Thisly will in tank body, be separated into top available space and bottom idle space and be the structure of so-called interlayer, although solved discharging problem, but a lot of defects have been brought: first it is evident that the degree of utilization that has reduced tank body volume thereupon, by the analysis of several existing railway bulk cement tanker capacity utilizations is found, its capacity utilization is all less than 82%; The center of gravity of next vehicle that raise, has reduced vehicle operating quality, and existing railway bulk cement tanker height of gravitational center is generally at 2100～2300mm; Moreover labyrinth has strengthened tank body difficulty of processing in tank body, complicated supporting construction need to complete assembly welding in tank, has also brought hidden danger to safety in production, has also greatly increased tank body deadweight.Practice shows, tank body because local collapse or weld cracking in various degree also may appear in many-sided reason, causes discharging performance to reduce after transportation a period of time.Cement leakage, below interlayer, can not draw off also not easy to clean simultaneously, and long-term accumulated causes dead weight of vehicle constantly to increase, and makes user's missing-ton.
