Description
The utility model relates to a kind of reactor jar mechanically-sealing apparatus under high temperature, high pressure, middling speed, the deep-etching condition, and it is applicable to the sealing of industry reactor jars such as chemical industry, light industry, medicine, metallurgy, food.
The all mechanically-sealing apparatus of existing reactor jar, kind is more, and structure is different, but is used for the few in number of HTHP middling speed deep-etching condition.Also there is weak point fully, this practical example of Chinese patent 942425413 vesselseals devices, though adopt the dismountable type bearing to connect, dismantle more convenient, but still need dismounting hang out the former moving reductor in top, motor, still show time-consuming, and still have fit clearance during the dismountable type bearing operation, still serious at high speed running middle (center) bearing and sealing part abrasion, it is frequent that part is changed in maintenance.
The utility model, be based on dismantling more convenient, more reasonable structure, sealing effectiveness is better, longer service life and designing has overcome the deficiencies in the prior art.
By the reactor jar mechanically-sealing apparatus of this purpose design, comprise stationary ring, rotating ring, O shape rubber ring, spring, axle sleeve, coupling assembly, seal receptacle, seal box, bearing block, gap bridge axle and lubricating and cooling system up and down.Be characterized between speed reducer output shaft and the shaft that be provided with the interior step of seal receptacle and place restrictions on the axle downslide of passing a bridge, the span of opening that supplies dismounting is left in its upper end, is provided with the coupling assembly of self-regulated axis transmission whereby.Be that the first line of a couplet cooperates with output shaft, the second line of a couplet is slidingly matched with the axle of passing a bridge, and the centre is equipped with middle, claw aligning device, rubbing property of composition transition self-regulated journal offset shaft coupling assembly.Axle sleeve and sealing function spare are equipped with in a gap bridge axle stage casing, reach the purpose of sealing.
The utility model and same device technology are according to following advantage is arranged:
1. coupling assembly, come loose caging bolt and first line of a couplet bolt, middle can radially shifting out forms neutral gear (axle of passing a bridge this moment place restrictions in seal receptacle on the step).Following related components is dismounting one by one all.
2. the axle of passing a bridge has drawn back spacing with output shaft, and joins among the coupling assembly, the transition each other of claw aligning device, rubbing property, self-regulated axis drive mechanism, and easy for installation, saving of work and time, maintenance cost is low.
3. in seal receptacle is designed to stretch still jar neck, give reasonable assembly space of bearer ring, it and upper bearing constitute the steady running bridge location, and the heavy curtain of having controlled the seal section axle is moving, and its sealing mechanism, performance further improve, and seal life prolongs, and produces continual and steady.
4. the axle of passing a bridge can dock in the seal receptacle, overcome shaft whereabouts accident and careless because of installing, accidents such as the broken frangible silicon ceramic ring of the improper sled of the application of force, having overcome auxiliary maintenance, to change part labour intensity big, auxilliary worker is many, delay time at stop is long, needs lifting not hang out time-consuming troubles such as heavy machinery fully, drawbacks such as influence production.
Accompanying drawing is reactor jar mechanically-sealing apparatus example structure master cutaway view.Its axle of passing a bridge upward connects with speed reducer output shaft by coupling assembly; Tighten with shaft nose cone face screw thread down and be connected.Seal receptacle flange and still jar neck fastening connection of flange bolt, TA type frame (not shown) carrying reductor and motor promptly are this structure accompanying drawing in the empty frame under the frame.
Now embodiment describes in detail in conjunction with the accompanying drawings.
