Abstract
The utility model discloses a silicon nitride ceramic lining elbow which comprises an elbow main body and a silicon nitride ceramic lining arranged in the elbow main body, wherein the silicon nitride ceramic lining comprises a plurality of mutually connected silicon nitride ceramic lining rings which are same in internal diameters, and the thickness of the silicon nitride ceramic lining rings on the outer diameter of the elbow main body is more than that of the silicon nitride ceramic lining rings on the inner diameter of the elbow main body. According to the silicon nitride ceramic lining elbow disclosed by the utility model, by adopting the silicon nitride ceramic lining, the impact abrasion of the elbow main body can be reduced greatly; and because the impact abrasion of the outer diameter of the silicon nitride ceramic lining is more than that of the inner diameter of the silicon nitride ceramic lining, the thickness of the silicon nitride ceramic lining on the outer diameter of the elbow main body is more than that of the silicon nitride ceramic lining on the inner diameter of the elbow main body, and the service life of the elbow main body can be further prolonged.
Description
Technical field
The utility model relates to the pipeline field, refers to especially a kind of silicon nitride ceramics liner elbow.
Background technique
The concrete mixer pipeline will be subject to the erosion effect of concrete mix in long-term using process, especially pipeline connecting bend place is because of the concrete mix moving direction generation centrifugal action that changes, the impact abrasion that bear in elbow external diameter place is the most serious, even worn out, the elbow wear rate is higher than the straight pipe portion figure place doubly.Employing that existing concrete mixer elbow of pipeline has increases the pipeline inner wall metal thickness, the employing wear resistant alloy material that has, and increasing the service life, but cost is high, and effect is ideal not to the utmost.Adopt the paster silicon nitride ceramics can solve wear-resisting problem, but paster comes off easily, in case near the silicon nitride ceramics sheet that comes off can causing and then comes off, affect the working life of elbow, pipeline.
The model utility content
The utility model proposes a kind of silicon nitride ceramics liner elbow, solved the serious problem of elbow impact abrasion in the prior art.
The technical solution of the utility model is achieved in that
A kind of silicon nitride ceramics liner elbow comprises:
The elbow main body;
The silicon nitride ceramics liner, be arranged in the described elbow main body, comprise some interconnective silicon nitride ceramics inner bushing rings, described silicon nitride ceramics inner bushing ring internal diameter is identical, described silicon nitride ceramics inner bushing ring at the thickness of described elbow main body outer radius greater than its thickness at described elbow inner major diameter place.
Further, this silicon nitride ceramics liner elbow also comprises:
Circular groove is arranged at two ends in the described elbow main body.
Further, this silicon nitride ceramics liner elbow also comprises:
The high temperature resistance and high strength inorganic binder, be arranged between the described silicon nitride ceramics inner bushing ring and described silicon nitride ceramics inner bushing ring and described elbow main body inner wall between.
The beneficial effects of the utility model are:
1, adopts the silicon nitride ceramics liner, can greatly reduce the impact abrasion of elbow main body, and abrasion is large than silicon nitride ceramics liner inner radius impact grinding degree of corrosion because silicon nitride ceramics liner outer radius is hit, make thickness that the silicon nitride ceramics liner is positioned at elbow main body outer radius greater than its thickness that is positioned at elbow inner major diameter place, can further improve the working life of elbow main body.
2, two ends are provided with circular groove in the elbow main body, in the circular groove back-up ring can be set, and stop and compress the silicon nitride ceramics inner bushing ring, make structure more solid and reliable.
3, the high temperature resistance and high strength inorganic binder can make between the silicon nitride ceramics inner bushing ring and silicon nitride ceramics inner bushing ring and elbow main body inner wall between be connected closelyr, make structure more solid and reliable.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of silicon nitride ceramics liner of the utility model elbow;
Fig. 2 is the radial cross-section of a kind of silicon nitride ceramics liner of the utility model elbow.
Among the figure:
1, elbow main body; 2, silicon nitride ceramics inner bushing ring; 3, circular groove.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1-2, a kind of silicon nitride ceramics liner elbow described in the utility model comprises:
Elbow main body 1;
The silicon nitride ceramics liner, be arranged in the elbow main body 1, comprise some interconnective silicon nitride ceramics inner bushing rings 2, silicon nitride ceramics inner bushing ring 2 internal diameters are identical, silicon nitride ceramics inner bushing ring 2 at the thickness of elbow main body 1 outer radius greater than its thickness in elbow main body 1 inner radius.
Wherein, adopt the silicon nitride ceramics liner, can greatly reduce the impact abrasion of elbow main body, and abrasion is large than silicon nitride ceramics liner inner radius impact grinding degree of corrosion because silicon nitride ceramics liner outer radius is hit, make thickness that the silicon nitride ceramics liner is positioned at elbow main body 1 outer radius greater than its thickness that is positioned at elbow main body 1 inner radius, can further improve the working life of elbow main body 1.
Silicon nitride ceramics liner elbow described in the utility model also comprises:
Circular groove 3 is arranged at elbow main body 1 interior two ends.
Wherein, elbow main body 1 interior two ends are provided with circular groove 3, in the circular groove 3 back-up ring can be set, and stop and compress silicon nitride ceramics inner bushing ring 2, make structure more solid and reliable.
Silicon nitride ceramics liner elbow described in the utility model also comprises:
The high temperature resistance and high strength inorganic binder, be arranged between the silicon nitride ceramics inner bushing ring 2 and silicon nitride ceramics inner bushing ring 1 and elbow main body 1 inwall between.
Wherein, the high temperature resistance and high strength inorganic binder can make between the silicon nitride ceramics inner bushing ring 2 and silicon nitride ceramics inner bushing ring 2 and elbow main body 1 inwall between be connected closelyr, make structure more solid and reliable.
Silicon nitride ceramics liner elbow described in the utility model can be carried 10-15 ten thousand side's concrete, and the plain carbon steel elbow only can be carried 3-5 ten thousand side's concrete, therefore, silicon nitride ceramics liner elbow described in the utility model is more than 3 times of like product working life.
The above only is 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 modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
