Description
Technical field
The utility model belongs to the technical field of aluminium cell feed device or shell shredder assembly, promptly relates to a kind of novel aluminum cell crust breaker.
Background technology
In the Aluminium Electrolysis, add aluminum oxide by the point feeding device in electrolyzer in recent years, the aluminum oxide gradation that can control weight joins in one or more hole to be close to the successive mode.But because there is the harder electrolyte crust of one deck on the fused electrolyte surface above electric tank cathode, so must on the shell face, make a call to a hole as feed opening earlier with the crust breaker of electrolyzer before feeding intake.
Existing crust breaker is made up of the cylinder of air-operated drive, hammer stem, tup, bearing, sealing member etc.The crust breaker cylinder adopts the middle part hinged-support to connect, and hammer stem and tup one are established the mode of sealing in hammer stem and horizontal cover plate junction.The crust breaker of this structure, cylinder in when action because the existence of side force, unavoidably to drive hammer stem and tup beat, the sealing of hammer stem and horizontal cover plate is again a little less than the relative thin, the result of various factors comprehensive action makes the sealing effectiveness variation, cause the flue gas of electrolyzer to overflow from seal point in a large number, environment in the workshop is caused bigger pollution.In addition, after tup damages,, tup need be sliced off when changing again, then new tup be burn-on the operation complexity because hammer stem and tup are one.
The utility model content
The utility model purpose is exactly to solve the sealing problem of crust breaker and pot superstructure and the maintenance issue of tup and sleeve mechanism.
The utility model discloses a kind of electrolysis of aluminum crust breaker, it comprises parts such as cylinder, cylinder end seat, tup, orienting sleeve, be connected with the guidepost in round cross section with bearing pin at circular tup afterbody, guidepost is connected with the axis of the piston of cylinder by joint pin, there is guide pipe the outside of guidepost, guide pipe is connected with cylinder by bolt, and whole device is installed on the aluminium cell by cylinder end holder assembly and orienting sleeve assembly.Tup of the present utility model is owing to adopted guide frame, make its reliable operation, be convenient to maintenance, and flexible sealing and insulation have been designed in the bottom of guide frame, on the cylinder end seat, be provided with locking, sealing and insulation system, satisfied that modern large-scale pre-baked cell structural integrity is strong, the requirement of superstructure positiver sealing.
The crust breaker that the utility model provides comprises rear end cap fixed cylinder, end hold-down gear, hammer stem, tup, it is characterized in that:
(1) rear end cap of cylinder is provided with insulating trip and fixes and be sealed in by the top hold-down gear on the crossbeam of pot superstructure;
(2) cylinder piston connects with the hammer stem upper end by universal joint;
(3) hammer stem and tup are dismountable minute body structure, and both connect with bearing pin.
The utility model aluminium cell crust breaker, the periphery of (front end) hammer stem is equipped with orienting sleeve below cylinder.Orienting sleeve not only has guide function, or the firm support of hammer stem and complete assembly, and its top is connected with cylinder; The lower end is provided with special flexure spring and compresses cone structure and seal with hammer stem.
Bearing pin outside between hammer stem of the present utility model and the tup is equipped with protection sleeve.It can avoid the corrosion of bearing pin, can install and remove easily and keep in repair to guarantee hammer stem and tup.
The flexure spring of orienting sleeve of the present utility model lower end compresses cone structure to be made up of seal cartridge and holddown spring, and seal cartridge is made of for upper and lower two sections tapered tube and cylindrical tube, and its top is fixed on the orienting sleeve with holddown spring and retaining criminal facts.Seal cartridge leads, the intensity height, it by high temperature resistant, intensity is high, the insulating material of good toughness is made; Holddown spring is then made by high temperature resistant, antimagnetic stainless material.
Crust breaker of the present utility model is owing to all have sealing at the end cap of cylinder and the junction of orienting sleeve and horizontal cover plate, so good sealing effect; Cylinder adopts the end to fix, and the upper end cover of cylinder and certain position of pot superstructure are strengthened, and in conjunction with the firm support of orienting sleeve at horizontal cover plate place, the action of cylinder is stable, has avoided beat; The upper end cover of cylinder and superstructure adopt the crimping mode, make things convenient for the dismounting of sleeve mechanism; The star coupling of hammer stem and cylinder is connected the adaptability that has strengthened the hammer stem action, has avoided jam; The orienting sleeve that hammer stem is outer not only plays constraint and guiding to hammer stem, and also is the constraint and the guide frame of complete assembly in conjunction with cone-shaped sealed gland etc., itself also helps being provided with suitable sealed structure.In order to improve the contact strength between orienting sleeve and horizontal cover plate, improve the sealing effectiveness of sleeve mechanism, establish the conical surface seal structure of spring application in the bottom of orienting sleeve, the conical surface seal cover of sealed structure is by having sufficient intensity and the flexible insulating material is made, spring wherein can compensate installation error, and act on cone-shaped sealed gland and improve sealing effectiveness, it is long-pending and improved intensity that the seal cartridge of taper has then increased sealing contact surface.
Description of drawings
Fig. 1 is the crust breaker of utility model, among the figure: 1 cylinder, 2 upper end covers, 3 end hold-down gears, 4 star couplings, 5 hammer stems, 6 tups, coupling device between 7 hammer stems and tup, 8 orienting sleeves, 9 conical surface seal covers, 10 spring attachments, 11 pot superstructure crossbeams, 12 horizontal cover plates.
Embodiment
Below in conjunction with drawings and Examples content of the present utility model is further described and replenishes:
