Abstract
The utility model relates to a ceramic inner lining cladding steel tube scratch-free fixed sleeve for a centrifugal machine, which is characterized in that a section tube of the centrifugal machine is provided with a long slot in the axial direction, and a sliding spiral sleeve is sleeved outside the section tube, and the sliding spiral sleeve is provided with a bolt, and the other end of the bolt passes through the sliding spiral sleeve to extend into the long slot of the section tube. For the other end of the bolt passes through the sliding spiral sleeve to extend into the long slot of the section tube, the bolt moves along with the thermal inflation of the steel tube and can be free to move towards both ends of the steel tube, so that the bolt is free from producing scratch on the outer wall of the ceramic inner lining cladding steel tube.
Description
Technical field
The utility model relates to the fixed cover that a kind of centrifugal process prepares processed steel pipe in the ceramic-lined composite steel tube centrifuge type pipe.
Background technology
When centrifugal process prepares ceramic-lined composite steel tube, because the temperature of steel pipe is very high in the course of reaction, reach more than 1000 ℃, 10 meters long steel pipes can extend 110mm.Do not move if the set bolt on the type pipe does not rise with the heat of steel pipe, will on steel pipe, mark one zanjon, influence the quality of ceramic-lined composite steel tube.
The utility model content
Technical problem to be solved in the utility model provides a kind of centrifuge of avoiding the ceramic-lined composite steel tube outer wall to scratch ceramic-lined composite steel tube no marking fixed cover.
For solving the problems of the technologies described above, the utility model provides a kind of centrifuge ceramic-lined composite steel tube no marking fixed cover, it is characterized in that: axially have penetrating elongated slot on the type pipe of centrifuge, the type pipe is with the slippage swivel nut outward, be fixed with bolt on the slippage swivel nut, the bolt other end passes the slippage swivel nut and stretches in the elongated slot on the type pipe.
The utility model is because the bolt other end passes the slippage swivel nut stretches in the elongated slot on the type pipe, so bolt rises with the heat of steel pipe and move, can be unobstructed with steel pipe to the two ends slippage, thereby bolt does not produce cut at the outer wall of ceramic-lined composite steel tube.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, on the type pipe 2 of centrifuge, leave penetrating elongated slot on the one hand, the width of groove is than bolt 3 slightly larger in diameter, and the length of groove adds that by half of the machined steel tubular axis thermotropism amount of rising 20mm calculates; On the other hand, do slippage swivel nut 1, the internal diameter of slippage swivel nut is slightly larger than the type external diameter of pipe, can slide on the type pipe, and the thickness of slippage swivel nut and width are by the size decision of bolt.
During use, the steel pipe that installs thermite is put into centrifuge, each slippage swivel nut is shifted to the middle part of the elongated slot of type pipe, fix each bolt then respectively.After lighting thermite, steel pipe is red heat gradually, expands to two ends.Because the bolt other end passes the slippage swivel nut and stretches in the elongated slot on the type pipe, can be unobstructed with steel pipe to the two ends slippage, thereby bolt does not produce cut at the outer wall of ceramic-lined composite steel tube.
Claims (1)
1, a kind of centrifuge ceramic-lined composite steel tube no marking fixed cover, it is characterized in that: axially have penetrating elongated slot on the type pipe of centrifuge, the type pipe is with the slippage swivel nut outward, is fixed with bolt on the slippage swivel nut, and the bolt other end passes the slippage swivel nut and stretches in the elongated slot on the type pipe.
