Abstract
The invention discloses a kind of energy-conservation self-boiling point feeding device, including Pneumatic reversal valve (1), cylinder (2) and pilot sleeve (4), the top of pilot sleeve (4) is provided with cylinder exhaust pipe joint (3), having injection hole (6) on the guide cylinder (4) of piston (7), the present invention utilizes inblock cylinder to go out gas, the upper and lower space pressure of dummy piston, excessive gas utilizes the hole winding-up material being located on sleeve, makes material reach fluidization.
Description
Technical field
The invention belongs to aluminum oxide in aluminum electrolytic bath feeding device field, be specifically related to a kind of energy-conservation self-boiling point feeding device.
Background technology
Tradition prebaked cell for aluminum-reduction point feeding device is affected by material flow performance and self structure, and quantitative accuracy is poor；For increasing the mobile performance of material, in hopper, generally increase compressed air spraying, to reach the purpose of boiling material.On the one hand point feeding device cylinder needs consumption of compressed air, and the material that is used for seething with excitement is also required to consumption of compressed air, say, that energy consumption is bigger.On the other hand, there is gas volume change between conventional port blanking device piston top air chamber at the volley and material room, bottom, thus cause air chamber internal gas pressure change, formation gas swabbing effect: piston coordinate with cylinder anchor ring because of negative pressure inspiration material and wear and tear；Cylinder charge port area material leakage in blanking stroke；In charge stroke, because of gas barrier, charge is discontented with.
Content of the invention
The technical problem to be solved in the present invention: overcome the deficiency that prior art exists, the present invention utilizes inblock cylinder to go out gas, the upper and lower space pressure of dummy piston, and excessive gas utilizes the hole winding-up material being located on sleeve, makes material reach fluidization.
The technical solution used in the present invention: a kind of energy-conservation self-boiling point feeding device, including cylinder and pilot sleeve, the top of pilot sleeve is provided with cylinder exhaust pipe joint, is having injection hole on the guide cylinder of piston.
Described one energy-conservation self-boiling point feeding device, is provided with Pneumatic reversal valve in cylinder head.
Described one energy-conservation self-boiling point feeding device, is connected with cylinder exhaust pipe joint between cylinder and pilot sleeve.
Described one energy-conservation self-boiling point feeding device, injection hole is provided with more than one.
The beneficial effect that the present invention reaches: cylinder is provided with Pneumatic reversal valve, shortens air tubing length as far as possible, and cylinder can be made to be swift in motion；Cylinder exhaust is accessed pilot sleeve, keeps air chamber to be pressure-fired at blanking stroke, at charge stroke, a large amount of rich gases are used for fluidization of material winding-up；Multiple injection hole is opened on guide cylinder near piston, in the cylinder Suo Pai volume expansion rear gas chamber accessing, pressure is substantially increased, the rich gas that will have 90 ~ 95% discharges winding-up material from injection hole, makes the fluidization of material near injection hole, forms the exchange of gas material space.
Patented technology of the present invention utilizes inblock cylinder to go out gas, the upper and lower space pressure of dummy piston, and excessive gas utilizes the hole winding-up material being located on sleeve, makes material reach fluidization.Reuse the gas that cylinder is sent, the purpose of the material that both reached to seethe with excitement, also can the pressure of the upper and lower chamber of dummy piston, reduce leakage, increase quantitative accuracy, also reduce compressed-air actuated consumption simultaneously, reach energy-conservation effect.
Brief description
Fig. 1 is the schematic diagram of the energy-conservation self-boiling point feeding device of the present invention.
Specific embodiment
Energy-conservation self-boiling point feeding device, including Pneumatic reversal valve the 1st, cylinder the 2nd, pilot sleeve the 4th, valve rod the 5th, piston 7 and piston spiracle 8, the top of pilot sleeve 4 is provided with cylinder exhaust pipe joint 3, at the injection hole 6 opening more than 1 on the guide cylinder 4 of piston 7, Pneumatic reversal valve 1 is against cylinder 2, cylinder 2 is accessed pilot sleeve 4 by cylinder exhaust pipe joint 3, by Pneumatic reversal valve with cylinder against configuration, shorten the length of pipeline as far as possible, the action that can make cylinder reaches quick, so can avoid the dynamic material leakage of baiting valve；About 0.45MPa compressed air in cylinder 2 is entered in the air chamber that guide cylinder 4 and piston 7 are isolated by pipe joint 3: in blanking stroke, piston 7 moves down, piston 7 upper chamber volumetric spaces becomes big, after the arranged volume expansion of cylinder 2 accessing, 85 ~ 90% are used for balance space pressure reduction, remaining 10 ~ 15% throttles outer row through the spiracle 8 on piston 7, now piston 7 upper chamber keeps pressure-fired, so can avoid injection hole 6 material leakage, and the annular space between piston 7 and guide cylinder 4 does not feeds because of pressure-fired；The gas of spiracle 8 is discharged from piston 7 10 ~ 15% makes piston 7 lower area of short duration for pressure-fired, material can be greatly decreased and leak from charge mouth.In charge stroke, piston 7 moves up, piston 7 upper chamber volumetric spaces diminishes, in the cylinder 2 Suo Pai volume expansion rear gas chamber accessing, pressure is substantially increased, the rich gas that will have 90 ~ 95% discharges winding-up material from injection hole 6, make the fluidization of material near injection hole 6, form the exchange of gas material space；Other 5 ~ 10% rich piston spiracles 8 from piston 7 for the gas are discharged, and accelerate the gas material space exchange between charge mouth and injection hole 6, and the air making the material under piston 7 indoor is exchanged by gas material space and makes material room filling rate be guaranteed and improve quantitative accuracy.
