Abstract
The utility model discloses a wear-resistant ceramic short pipe, which comprises a short pipe main body, wherein the short pipe main body is provided with wear-resistant cement; the wear-resistant cement is adhered to the outer wall of the short pipe main body to form an adhesive layer; a bushing is also sleeved outside the short pipe main body; one end of the bushing is provided with a baffle; and the adhesive layer is adhered to the short pipe main body and the inner wall of the bushing. The wear-resistant ceramic short pipe is convenient to mount, can be randomly disassembled and replaced, has the characteristics of material saving, high temperature resistance, high rigidity, high strength, scour resistance, superior thermal shock resistance, firmness and durability and the like; construction period is reduced and cost is saved; and the wear-resistant ceramic short pipe is suitable for various large-sized refineries and has high popularization and application values.
Description
[technical field]
The utility model relates to the wear-resistant ceramic short tube of the parts in a kind of petrochemical plant, particularly a kind of long service life.
[background technique]
The environment of employed catalysis device inside, petrochemical industry refinery is that the high speed that is in high-temperature flue gas and big flow catalyzer is washed away the state with high temperature oxidation and corrosion, the vitals short tube of the abominable Environmental Conditions claimed apparatus inside of this high temperature and high speed has very high abrasion resistance properties, and good stupalith is made so the short tube in the present catalysis device adopts wear resistance mostly.But the mounting structure complexity and the waste material of existing ceramic short tube, it is to be installed among the Bai Gangguan again after short tube is carried out, this just must cut Bai Gangguan to be incorporated on the short tube open by middle footpath and welding of longitudinal seam be synthesized later on again, Bai Gangguan is welded on the employed position then, owing to be to connect with Type of Welding, so can not change at any time, have a strong impact on ordinary production, so that cause repairing and increase cost.
[model utility content]
The purpose of this utility model is: overcome the deficiencies in the prior art, provide a kind of mounting structure simple wear-resistant ceramic short tube.
The purpose of this utility model is achieved in that it comprises the short tube main body, and its improvements are: the short tube main body is provided with wear-resistant daub, and wear-resistant daub is adhered on the outer wall of short tube main body and forms adhesive layer; The short tube main body is arranged with sleeve pipe outward, and an end of sleeve pipe is provided with closure plate, and adhesive layer is adhered to the inwall of short tube main body and sleeve pipe;
In the above-mentioned wear-resistant ceramic short tube, the external diameter of described sleeve pipe is identical with the external diameter of short tube main body, offer the annular mounting groove that vertically extends to short tube main body one end on the outer wall of short tube main body, the cylindrical groove wall section of the annular mounting groove of short tube main body inserts in the sleeve pipe, and adhesive layer is adhered between the inwall of the cylindricality cell wall of annular mounting groove and sleeve pipe; On sleeve pipe, be provided with closure plate in an end relative with the direction of insertion of short tube main body;
In the above-mentioned wear-resistant ceramic short tube, described short tube main body is by mullite corundum and the compression moulding of rare metal batching.
With respect to existing ceramic short tube, the beneficial effects of the utility model are: have high temperature resistant, characteristics such as hardness is big, intensity is high, antiscour, thermal shock resistance are good, sturdy and durable, it is convenient to install, can change at any time, and can save cost, saving duration, be applicable to that various large-scale refineries use, and have large-scale promotion, use value; Acid resistant adhesive mortar bonding firmly, the main body of short tube plays purpose high temperature resistant, that rub resistance prolongs its working life by mullite corundum and rare metal preparation to short tube.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the structural representation of the utility model wear-resistant ceramic short tube
Among the figure: 1, short tube main body; 2, annular mounting groove; 3, cylindricality cell wall; 4, annular end face; 5, wear-resistant daub; 6, sleeve pipe; 7, closure plate.
[embodiment]
As shown in Figure 1, wear-resistant ceramic short tube of the present utility model mainly comprises short tube main body 1 and adhesive layer, and for fixing and protection short tube main body 1, sleeve pipe 6 and closure plate 7 can be set outside short tube main body 1.Short tube main body 1 is through the compression moulding of mullite corundum and rare metal batching, through dry in the shade, the merit preface is refining forms for oven dry, roasting etc., it has increased considerably the high temperature resistant and crocking resistance of short tube.Adhesive layer on the short tube main body 1 is to be formed by the wear-resistant daub 5 that directly is adhered on short tube main body 1 outer wall, and the short tube that applies the wear-resistant daub 5 of knowing clearly can directly be in place, i.e. saving of labor's material-saving again.The adhesive property of wear-resistant daub 5 is strong, can effectively ensure the firm reliability of installation.In order to reach the protection purpose, sleeve pipe 6 is sheathed on outside the short tube main body 1, short tube main body 1 is inserted in it from an end of sleeve pipe 6, and on sleeve pipe 6 the end fixedly connected closure plate 7 relative with direction of insertion.The external diameter of sleeve pipe 6 is identical with the external diameter of short tube main body 1, on the outer wall of short tube main body 1, offer the annular mounting groove 2 that vertically extends to short tube main body 1 one ends, the internal diameter of sleeve pipe 6 matches with the external diameter of cylindricality cell wall 3 parts of annular mounting groove 2, on cylindricality cell wall 3, evenly apply one deck wear-resistant daub 5, cylindricality cell wall 3 parts of short tube main body 1 are inserted in the sleeve pipe 6, connect until the end face of sleeve pipe 6 and the annular end face 3 of annular mounting groove 2, wear-resistant daub 5 is adhered between the inwall of the cylindricality cell wall 3 of annular mounting groove 2 and sleeve pipe 6, forms firm connection.
The size of the wear-resistant ceramic short tube that this is novel can be according to the customization of user's required size, and it is convenient that its structure is installed, changed, labor and material saving, and also sturdy and durable, long service life.
Described above only is preferred embodiment of the present utility model; above-mentioned specific embodiment is not to restriction of the present utility model; the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
