Lifting type material transportation tank car in Environmental protection all-closed formula building material production equipment provided by the invention is base In particulate material Bulk Transport and the vehicle of special transport mortar raw material developed, which is hydraulic lifting gas suspension Centrum feed bin unloading type structure, has the characteristics that energy conservation and environmental protection is high-efficient.
The intracorporal mortar raw material of tank is lifted to design angle by tank body first, and gravity is recycled to flow to the discharging of rear end centrum Mouthful, tank interior is inflated at this time, and after pressure inside the tank reaches 0.2Mpa, opening valve can discharging.
The discharging principle of lifting type material transportation tank car of the present invention
Tank body is lifted using hydraulic hoist cylinder when discharging principle is discharging, makes material concentrate on tank body centrum discharge port to be in Landslide situation, at this time gas suspension by mortar raw material fluidize in centrum discharge port subrange, compressed gas to material by Layer peels off, and last mortar raw material is quickly drawn off through centrum discharge port, avoids the isolation that mortar raw material is generated by long agitation.
Air-flotation type discharging principle is in tank body subrange, by being blown into compressed air in the equally distributed gas of tank body Stream forms air cushion, the material after making floatingization through pipeline uniformly, steady, quickly discharging material, avoid generating the particle between material itself Phase mutual friction avoids large area, prolonged agitation from generating isolation, and the compressed gas that air compressor machine generates enters tank body by pipeline Tail cone discharge port forms " air knife ", tail portion material is successively discharged, does not influence material structure, and form rerolling.This Structure air consumption is small, residual rate is close to zero.Isolation problem in above feature effective solution mortar raw material discharge process. The transport of damp sand in mortar raw material can be easily accomplished.Simultaneously because having installed discharging cleaning plant additional, realize more than quickly cleaning Material, effective solution transport clout cannot remove and caused by mixing problem, ensure that the quality of mortar raw material.
The advantage of lifting type material transportation tank car of the present invention
1, lifting type material transportation tank car uses totally-enclosed transport, and entire logistics progress cleans, is environmentally friendly, is energy saving, efficiently.
2, discharge rate is fast, 1.2 tons per minute, shortens the discharge time, improves conevying efficiency;Extremely low surplus ratio is ten thousand / bis-, it is close to zero, saves material.
3, in order to meet the domestic requirement to dry-mixed mortar technical quality management regulation, lifting type material transportation tank car is configured Dedicated sampler, to ensure that the quality for monitoring and detecting mortar raw material in real time provides guarantee.
4, using hydraulic lifting tank, tilt angle is 45 degree.
5, the lower half of tank body has bonded silica gel plate, reduces frictional resistance, and damp sand is enable smoothly to slide into exit.
6, the tail portion of tank body is changed, and damp sand is enable to slide into the minimum position of tank bottom.
7, the tail portion lowest point of tank increases a T shape discharge port, ensure that the satisfaction of discharging.
In summary it states, lifting type material transportation tank car meets the traffic condition that damp sand enters tank.
Environment-friendly type mixing plant in Environmental protection all-closed formula building material production equipment of the invention is mixed suitable for microlith The preparation of solidifying soil and cement mortar:
Raw material needed for the environment-friendly type mixing plant produces can derive from following material:
1. urban building waste secondary use waste material, many kinds of when because of garbage reclamation, water content disunity causes to screen Raw material out cannot supply premixing mortar factory and directly use, which can be straight with raw material of the water content between 1-5% It accesses tank to use, in addition to fine sand and middle sand can produce good mortar, also produces microlith coagulation using 0.5-1 millimeters of aggregate Soil.
2. also directly entering tank production mortar and thin in the sand of 1-5% using water content in the case where dead meal shortage Stone concrete.
