Abstract
The invention discloses an energy-saving self-boiling point type discharging device comprising a reversing valve (1), an air cylinder (2) and a guide sleeve (4), wherein an air cylinder exhaust fitting (3) is arranged at the upper part of the guide sleeve (4); and blowing holes (6) are formed in the guide cylinder (4) in a position near a piston (7). According to the utility model, the air cylinder is utilized to exhaust gas, so as to balance the pressures of the spaces above and below the piston; and excess gas is utilized to blow materials through the blowing holes in the guide sleeve, so that the materials are fluidized.
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 from seething with excitement the point feeding device.
Background technology
The tradition prebaked cell for aluminum-reduction is subjected to the influence of raw material flowing property and self structure with the point feeding device, and quantitative accuracy is relatively poor; For increasing the flowing property of material, in hopper, increase compressed air spraying usually, to reach the purpose of boiling material.Point feeding device cylinder needs consumption of compressed air on the one hand, and the material that is used to seethe with excitement also needs consumption of compressed air, that is to say that energy consumption is bigger.On the other hand, conventional port blanking device piston exists gas volume to change between top air chamber and the bottom material chamber at the volley, thereby causes the air chamber internal gas pressure to change, and form the gas pumping effect: piston cooperates anchor ring to wear and tear because of negative pressure inspiration material with cylindrical shell; Cylindrical shell fills the material port area and leak material in the blanking stroke; In filling the material stroke,, gas-barrier is discontented with because of filling material.
Summary 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, and equalizing piston is space pressure up and down, and unnecessary gas utilization is located at the hole winding-up material on the sleeve, makes material reach fluidization.
The technical solution used in the present invention: a kind of energy-conservation point feeding device that seethes with excitement certainly, comprise cylinder and pilot sleeve, the top of pilot sleeve is provided with the cylinder exhaust pipe joint, is having injection hole near on the guide cylinder of piston.
Described a kind of energy-conservation from seething with excitement the point feeding device, be provided with Pneumatic reversal valve in cylinder head.
Described a kind of energy-conservation from seething with excitement the point feeding device, between cylinder and pilot sleeve, be connected with the cylinder exhaust pipe joint.
Described a kind of energy-conservation from seething with excitement the point feeding device, injection hole is provided with more than one.
The beneficial effect that the present invention reaches: be provided with Pneumatic reversal valve near cylinder, shorten tracheae length as far as possible, cylinder is swift in motion; The cylinder exhaust is inserted pilot sleeve, and keeping air chamber is pressure-fired at the blanking stroke, will a large amount of rich gases be used for fluidization of material and jets filling the material stroke; On near the guide cylinder the piston, open a plurality of injection holes, exhaust body volumetric expansion rear gas chamber of the cylinder institute internal pressure that inserts significantly rises, to there be 90 ~ 95% rich gas to discharge the winding-up material, make near the fluidization of material the injection hole, form the exchange of gas material space from injection hole.
Patented technology of the present invention utilizes inblock cylinder to go out gas, and equalizing piston is space pressure up and down, and unnecessary gas utilization is located at the hole winding-up material on the sleeve, makes material reach fluidization.The gas that utilizes cylinder to send had once more both reached the purpose of boiling material, but the equalizing piston pressure of chamber up and down also reduce and leak, increase quantitative accuracy, also reduce compressed-air actuated consumption simultaneously, reach energy-conservation effect.
Description of drawings
Fig. 1 is energy-conservation synoptic diagram from the point feeding device that seethes with excitement of the present invention.
Specific embodiment
Energy-conservation from seething with excitement the point feeding device, comprise Pneumatic reversal valve 1, cylinder 2, pilot sleeve 4, valve rod 5, piston 7 and piston ventilation breather 8, the top of pilot sleeve 4 is provided with cylinder exhaust pipe joint 3, on the close guide cylinder 4 of piston 7, open the injection hole 6 more than 1, Pneumatic reversal valve 1 is near cylinder 2, cylinder 2 is inserted pilot sleeve 4 by cylinder exhaust pipe joint 3, with Pneumatic reversal valve and cylinder near configuration, shorten the length of pipeline as far as possible, the action of cylinder is reached fast, can avoid baiting valve dynamically to leak material like this; About 0.45MPa pressurized air in the cylinder 2 is entered in guide cylinder 4 and the piston 7 isolated air chambers by tube stub 3: in the blanking stroke, piston 7 moves down, it is big that piston 7 upper chamber volumetric spaces become, 85 ~ 90% are used for balance space pressure reduction after 2 exhaust bodies of the cylinder volumetric expansion that inserts, all the other 10 ~ 15% ventilation breather 8 throttlings on piston 7 efflux, this moment, piston 7 upper chambers kept pressure-fired, can avoid injection hole 6 to leak material like this, and the annular space between piston 7 and the guide cylinder 4 is because of not charging of pressure-fired; Ventilation breather 8 is discharged from the piston 7 10 ~ 15% gas makes piston 7 lower regions are of short duration to be pressure-fired, can significantly reduce material and mouthful leak from filling material.In filling the material stroke, piston 7 moves up, piston 7 upper chamber volumetric spaces diminish, 2 exhaust bodies of the cylinder volumetric expansion rear gas chamber internal pressure that inserts significantly rises, to there be 90 ~ 95% rich gas to discharge the winding-up materials from injection hole 6, make near the fluidization of material the injection hole 6, form the exchange of gas material space; The piston ventilation breather 8 of other 5 ~ 10% rich gases from the piston 7 discharged, and quickens to fill the gas material space exchange between material mouthful and the injection hole 6, the indoor air of material under the piston 7 made by the exchange of gas material space expect that the chamber filling ratio is guaranteed and improve quantitative accuracy.
