Description
Technical field
the present invention relates to a kind of equipment of Aluminum Electrolysis Production, particularly relate to a kind of pressure shell device of self-adaptation type, belong to nonferrous metallurgical equipment design and manufaction technical field, be suitable for using at electrolytic aluminium factory.
Background technology
electrolytic aluminium factory produces former aluminium electrolyzer, groove upper surface forms comparatively hard coat in process of production, constantly consuming in raw materials for production situation and constantly must supplement new raw material, device must be had to open shell face for this reason, new raw material is supplemented to be entered in groove, carry out chemical reaction, current China electrolytic aluminium factory all uses crust breaker in production operation, tolerance consumption is large, energy consumption is serious, and pressure can not regulate, noise is serious, liner is not had in tup motion, make tup bumpy motion, double swerve, component very easily damage, maintenance service is heavy, have a strong impact on the production of groove, in the urgent need to retrofit.This self-adaptation pressure shell device does not also find to use in aluminium manufacturer of China, belongs to domestic initiation.
Summary of the invention
the object of the invention is to the problems referred to above solving prior art existence, provide a kind of groove self-adaptation pressure shell device of new texture, use this groove self-adaptation pressure shell device can reduce air consumption in a large number, save energy consumption, have operate steadily, long service life, be not easy to damage, maintenance is little and alleviate the feature of labor strength.
the technical solution adopted in the present invention is: this groove self-adaptation pressure shell device includes cylinder and tup, be characterized in that described cylinder bottom is provided with the combination valve block be combined into one by valve member used for speed and pressure-regulating, source of the gas enters in cylinder chamber by the valve member used of the variable voltage control in combination valve block, promote piston up-downgoing campaign, also include the lower guide ensureing that pressure shell tup operates steadily in groove self-adaptation pressure shell device, this lower guide be made up of sliding sleeve and guide cylinder is arranged on below cylinder.
object to better implement the present invention, is also provided with sensor and time controller in the combination valve block of pressure-adjustable speed governing.
namely object to better implement the present invention, adopt 4 place's seals in this groove self-adaptation pressure shell device: 1) cylinder permanent seat be provided with bearing between pot superstructure together with insulate, cylinder and upper part of the electrolytic cell mechanism are insulated; 2) be provided with between cylinder body with device bottom orienting sleeve together with insulate, insulate between cylinder and orienting sleeve; 3) be provided with between orienting sleeve with electrolyzer lower channel upper cover plate together with insulate, orienting sleeve and electrolyzer bottom are insulated; 4) be provided with between cylinder piston rod with movable hammer stem together with insulate, cylinder piston rod and movable hammer stem are insulated.
object to better implement the present invention, the pneumatic system of this groove self-adaptation pressure shell device is by preparing pressure shell pneumatic circuit, start pressure shell pneumatic circuit and the pressure shell pneumatic circuit that is hampered to form, wherein prepare pressure shell pneumatic circuit by source of the gas, reducing valve 3, two-position three way list gas control live reversing valve 4, two-position five-way list Pneumatic reversal valve 5, the cavity of resorption composition of one-way throttle valve 9 and cylinder 10, start pressure shell pneumatic circuit by source of the gas, two-position three way list electric control reversing valve 1, two-position five-way list Pneumatic reversal valve 5, the epicoele composition of one-way throttle valve 8 and cylinder 10, pressure shell is hampered pneumatic circuit by two-position three way list electric control reversing valve 2, two-position three way list Pneumatic reversal valve 4 and switch valve with two-position and five-pass 5, the epicoele composition of two-position three way list Pneumatic reversal valve 6 or two-position three way list electric control reversing valve 7 and cylinder 10.
after gas enters combination valve block, reached pressure and the speed of setting by speed and pressure-regulating, enter upper chamber of air cylinder, promote piston rod and run.If piston rod moves downward, when centre meets obstructions and moves stopping, in combination valve block, gas can not enter in upper chamber of air cylinder by straight channel by speed and pressure-regulating valve member, and the gas of high pressure high flow capacity makes piston rod sharp downward movement, impacts duricrust face.
in piston motion, piston rod slides and can only move up and down in slip cap, can not swing, and easy motion, without impacting, without swinging, in extension fixture work-ing life greatly, saves a large amount of maintenance workload.
automatically stop and commutating after putting in place, gas enters cavity of resorption, promotes piston rod and moves upward.Stop after putting in place, complete a circulation.If cylinder piston rod run downwards centre transport to resistance exercise stop time, in combination valve block, gas can not enter in upper chamber of air cylinder by straight channel by speed and pressure-regulating valve member, and the gas of high pressure high flow capacity makes piston rod sharp downward movement, impact duricrust face.
the present invention compared with prior art, its beneficial effect is: 1. when keeping original external conditions constant, this device that the present invention provides can under less tolerance air pressure, slow pressure shell is become by impact crust breaking, decrease device action frequency and energy transfer pressure and flow automatically, air capacity 30% can be saved than original crust breaker.For the aluminium manufacturer adopting 350KA electrolyzer to produce primary aluminum 100,000 tons of aluminium output, need crust breaker 636 to overlap, each crust breaker of pressure shell action every day comes and goes totally 2880 times, the annual total action frequency of 636 covering devices 668,5,600,000 times, air consumption about 6,680,000 m
3
, this device as adopted the present invention to provide can save 30% air capacity, about 2,000,000 m
3
, energy-conservation very remarkable with economic benefit that is that obtain.
without impact, nothing swing in this device busy that the present invention provides, equipment attrition reduces greatly, improves device lifetime, saves spare parts consumption and decreases maintenance amount, obvious minimizing while of spare part expense and maintenance cost.
meet environmental requirement, former crust breaker impulsive noise is very large, hundreds of covering device frequent movement, and noise is serious, and after making pressure shell device into, without impact, noiselessness, Working environment improves greatly.
