Abstract
The utility model proposes a kind of swivel joint of calcining kiln, comprise Stuffing box, be located at vapour axle inside Stuffing box and stuffing box packing, the position of the corresponding stuffing box packing of outer surface of described vapour axle is provided with layers of chrome.The swivel joint of the calcining kiln in the utility model, owing to being provided with layers of chrome in the position of the corresponding stuffing box packing of the outer surface of vapour axle, thus form wear-resisting sealing surface, there is the features such as intensity is high, wear-resisting, both the outer surface damaging this vapour axle can have been avoided, good sealing effect can be reached again, prevent the potential safety hazard caused due to problems such as wearing and tearing, leakages.
Description
Technical field
The utility model relates to soda industry apparatus field, refers to a kind of swivel joint of calcining kiln especially.
Background technique
The calcining kiln of soda industry is that to utilize the heat energy of steam will weigh alkali (sodium bicarbonate) calcining be the turning round equipment of soda ash (natrium carbonicum calcinatum), and the access of its steam and the discharge of lime set realize by swivel joint.Swivel joint is that medium pressure steam is input to heat up system of calciner from static duct, gets back to again the connection seal arrangement in another static duct after condensation., thus there is potential production dangerous, threaten the life safety of producers in the problems such as the revolving joint sealing structure of current use is simple, easy to wear, easy leakage.
Model utility content
The utility model proposes a kind of swivel joint of calcining kiln, solve the problems such as easy to wear in prior art, easy leakage.
The technical solution of the utility model is achieved in that
A swivel joint for calcining kiln, comprises Stuffing box, is located at vapour axle inside Stuffing box and stuffing box packing, and the position of the corresponding stuffing box packing of outer surface of described vapour axle is provided with layers of chrome.
Preferred version is, described stuffing box packing is expanded graphite packing.
Preferred version is, the swivel joint of described calcining kiln also comprises is located at lining inside Stuffing box and the Gland corresponding with lining, is enclosed to form the inner chamber filled out and establish stuffing box packing between described lining, Gland and vapour axle.
Preferred version is, described vapour axle in a circumferential direction, two axial positions offer two rounds, is respectively steam inlet and condensate outlet.
Preferred version is, jacket pipe structure centered by described vapour axle, comprises stream passageway and lime set passage.
The beneficial effects of the utility model are:
The swivel joint of the calcining kiln in the utility model, owing to being provided with layers of chrome in the position of the corresponding stuffing box packing of the outer surface of vapour axle, thus form wear-resisting sealing surface, there is the features such as intensity is high, wear-resisting, both the outer surface damaging this vapour axle can have been avoided, good sealing effect can be reached again, prevent the potential safety hazard caused due to problems such as wearing and tearing, leakages.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cross-sectional side view of the swivel joint of the utility model calcining kiln.
In figure:
10, the swivel joint of calcining kiln; 11, Stuffing box; 12, lining; 14, vapour axle; 15, Gland; 16, bolt; 140, stream passageway; 142, lime set passage; 141, steam inlet; 143, condensate outlet; 17, expanded graphite packing; 18, layers of chrome.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the swivel joint 10 of this calcining kiln comprises Stuffing box 11, is located at the lining 12 at Stuffing box 11 inner left, center, right three place, is located at vapour axle 14 inside this lining 12 and the Gland 15 that separately arrange corresponding to each lining 12 respectively.
Each Gland 15 fixes respectively by a bolt 16 and Stuffing box 11, and respectively and be enclosed to form one between lining 12 and vapour axle 14 and fill out the inner chamber establishing expanded graphite packing 17.
Jacket pipe structure centered by described vapour axle 14, is respectively stream passageway 140 and lime set passage 142, and this vapour axle in a circumferential direction, axially different position offers two rounds, is respectively steam inlet 141 and condensate outlet 143.The each position that the outer surface of described vapour axle 14 is corresponding with expanded graphite packing 17 is respectively equipped with layers of chrome 18, this layers of chrome 18 surface obtains smooth, wear-resisting sealing surface after grinding, there is the features such as intensity is high, wear-resisting, high temperature resistant, both the outer surface damaging this vapour axle 14 can have been avoided, good sealing effect can be reached again, prevent the potential safety hazard caused due to problems such as wearing and tearing, leakages.
Structure and the principle of the miscellaneous part in described calcining kiln swivel joint 10 are identical with of the prior art, do not repeat them here.
During concrete enforcement; the structure of the swivel joint 10 of described calcining kiln is not limited to the structure of above-described embodiment; it also can be the structure of the swivel joint that can be applicable to calcining kiln in other prior aries; such as application number is the structure etc. of calcining kiln swivel joint in 89202491.7; namely layers of chrome is provided with in the position of the corresponding stuffing box packing of outer surface of vapour axle 14; as long as the outer surface in the corresponding filler position of vapour axle 14 is provided with the technology of layers of chrome, all within protection domain of the present utility model.Described stuffing box packing can be expanded graphite packing, also can be the filler that other are suitable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
