The high pressure Dense Phase Pneumatic Conveying is widely used in coal gasification and relevant chemical field, and lock bucket system has been adopted in the processing of most of powder material and conveying.In the transformation delivery system of powder material, powder is uprised pressure, accomplished feed by low pressure is that process through transformation storehouse pressurization successively, blowing, pressure release, charging, the such repeat of pressurization realizes.But because complicated operation, fault rate is higher, and locks the phenomenons such as in the blanking process, being easy to generate knot arch, bridge formation that struggles against, and causes the instability of whole feedway.The desultory charging of the periodicity of material in the high-pressure delivery in addition is very easy to cause the fugitiveness of goods fluid and conveying, thereby influences the safe and stable operation of whole delivery system.
Summary of the invention
Goal of the invention: to the problem and shortage of above-mentioned existing existence, the purpose of the utility model has provided a kind of powder high pressure continuous conveying device, and he can provide successively and the pulsation-free powder is carried.
Technical scheme: for realizing the foregoing invention purpose; The utility model adopts following technical scheme: a kind of powder high pressure continuous conveying device; Comprise that first carries cylinder, second to carry cylinder, disjunctor hydraulic ram, driver train and high pressure feed bin, wherein, said disjunctor hydraulic ram comprises first hydraulic actuating cylinder and second hydraulic actuating cylinder that is respectively equipped with piston; Empty chamber, the same side of these two hydraulic cylinder pistons is communicated with through pipeline, and is filled with hydraulic oil; Said first carries cylinder and second to carry cylinder to be provided with piston, and is connected with the piston of first hydraulic actuating cylinder with second hydraulic actuating cylinder respectively through connecting rod, and said first carries cylinder and second to carry cylinder to be equipped with the feed pipe of conical discharge port and band valve; Said first carries cylinder and second to carry the discharging opening of cylinder to be connected with the high pressure feed bin, and said driver train is connected with two pistons of disjunctor hydraulic ram.
During work; Thereby the piston that under the effect of driver train, promotes first hydraulic actuating cylinder promotes the piston-advance of the first conveying cylinder; Thereby the powder of its front end is pushed into the discharging opening position; Under the effect of conical discharge port, make powder be compacted into piece, and be transported to the high pressure feed bin, thereby avoid the gas of high pressure feed bin to enter into the first conveying cylinder through discharging opening; Meanwhile the piston of first hydraulic actuating cylinder is clamp-oned the hydraulic oil of its empty chamber, left side the empty chamber, left side of second hydraulic actuating cylinder through pipeline; Make the piston reversing sense of second hydraulic actuating cylinder move; And then the piston that drives the second conveying cylinder is also done reverse moving; The valve open of opening feed pipe this moment drops into material, when next cycle, repeat above-mentioned first carry cylinder material conveying process, finally realize the conveying of the stable and continuous of powder.
As preferably; Said first carries cylinder and second to carry the front end of cylinder to be equipped with the buffering air chamber, and this buffering air chamber is connected with carrying cylinder separately through ventilative porous plate, thereby makes conveying cylinder air on the left of during feeding under the piston promotion can enter into surge chamber; Stop powder to get into surge chamber simultaneously in this; Avoid empty chamber, left side air pressure too high thereby reach, thus the compelled power that improves driver train, final energy savings.
As preferably, said first carries cylinder and second to carry the discharging opening of cylinder to be equipped with valve, thereby the high pressure gas of high pressure feed bin is poured in down a chimney to carrying in the cylinder when avoiding starting shooting at first.
Beneficial effect: compared with prior art; The utlity model has following advantage: under the control of hydraulic efficiency pressure system, utilize two reciprocating piston powder conveying cylinders to carry powder, realize the cycle alternation feed of twin-tub; Thereby the realization continuously and stably feeding, the stability of feed in the assurance stove.
