Description
Technical Field
The utility model relates to a bottom thickening high temperature resistant protection tube structure belongs to mould technical field.
Background
During work, the heater needs to be placed into high-temperature aluminum liquid for heating, but the temperature of the high-temperature aluminum liquid can reach 710 ℃, and the heater can be damaged, so that a protection tube needs to be designed to protect the heater.
Disclosure of Invention
The utility model aims to overcome the not enough of existence among the prior art, provide a high temperature filter screen forming device, can protect the heater to prevent and give outside aluminium liquid with aluminium liquid contact and conduction heat, the bottom thickening is difficult to break.
According to the utility model provides a technical scheme: a high temperature resistant protection tube structure with a thickened bottom comprises a protection tube body, wherein a heater is inserted into the protection tube body; the protection tube body comprises a tube body part and a tube bottom part, and the connection part of the tube body part and the tube bottom part is in arc transition; the thickness of the tube bottom is larger than that of the tube body.
Further, the thickness of the bottom of the pipe is 23-25mm, and the thickness of the pipe body is 13-15 mm.
Further, an annular groove is formed in the upper portion of the protection tube body.
Further, the protection tube body is made of silicon carbide materials.
Compared with the prior art, the utility model, have following advantage:
1. the heater can be protected from contacting with the aluminum liquid and can conduct heat to the external aluminum liquid.
2. The bottom is thickened and is not easy to break.
3. Simple structure and good practicability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of a protective tube body.
Description of reference numerals: 1-protecting the tube body, 2-heater, 3-tube body, 4-tube bottom and 5-ring groove.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a high temperature resistant protective tube structure with a thickened bottom comprises a protective tube body 1, wherein a heater 2 is inserted into the protective tube body 1; the protection tube body 1 comprises a tube body part 3 and a tube bottom part 4, and the connection part of the tube body part 3 and the tube bottom part 4 is in arc transition; the bottom tube part 4 has a greater thickness than the shaft tube part 3.
The thickness of the tube bottom part 4 is 23-25mm, and the thickness of the tube body part 3 is 13-15 mm.
Two annular grooves 5 are formed in the upper portion of the protection tube body 1, and the annular grooves 5 are matched with annular metal buckles to fix the protection tube body 1.
The utility model relates to a protection tube structure of bottom thickening, the during operation inserts heater 2 into protection tube body 1 the inside, and protection tube body 1 is put in high temperature aluminium liquid the inside, and heater 2 can not contact with aluminium liquid like this, and the protection tube is that the heat conduction material is done, and the preferred adoption adopts carborundum material. When the heater 2 works, heat can be conducted to the external aluminum liquid, and the function of heating the aluminum liquid is achieved. The bottom of the protection tube body 1 is thickened and is thicker than the wall thickness of other places. The temperature of the aluminum liquid is more than 710 ℃.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
