Abstract
The utility model provides a heat conductive oil bushing, which consists of an insulating layer, a bushing, and a liner tube from exterior to interior; the insulating layer is coated on the outer surface of the bushing; and a heat conductive oil runner is arranged between the bushing and the liner tube. The liner tube and the bushing of the heat conductive oil bushing are manufactured by excellent seamless steel tubes; the heat conductive oil bushing can be welded and connected with other equipment through flanges; the heat conductive oil runner is arranged between the bushing and the liner tube; the insulating layer which is a fiberglass cotton layer is coated on the edge of the bushing to protect the heat of the heat conductive oil from missing and realize long-distance transportation of wax liquid. Through field testing, the temperature difference between the front end and the back end of the heat conductive oil bushing is less than plus or minus1DEG C; and the implementation effect is very ideal.
Description
Technical field
The utility model relates to a kind of conduction oil sleeve pipe.
Background technique
Existing precision casting machinery or all kinds of production lines mostly are the separate unit serial connection and are provided with, with wax material processing technology line is example, relevant device has the wax of melting equipment, system cream equipment, pressure injection equipment, dewaxing equipment etc., old type equipment and most user generally adopt each unit independently to be provided with, particularly under big place, remote distributional condition, in view of factors such as the insulation of wax material, monitoring, controls, the contact of equipment room can only be taked pipeline to connect to add the method that manual delivery combines on the production line.
Wax material is from being dissolved to forming process, and its state is that the solid-state form of paste is carried out the technology circulation, during temperature generally be controlled at press temperature 56-60 ℃ ± 5 ℃ in.Therefore, the temperature control of wax material circulation process is very important.Prior art is carried for remote circulation: the general pipeline outer wall resistive method that adopts of control, to be wound in pipeline or tank body outside by variety of way from the temperature control electric-heating belt, and then laying thermal insulating material, link to each other with temp controller with the operation of accurate control from temperature control electric-heating belt one end from the temperature control electric-heating belt, when temperature transducer detects pipe temperature and is lower than the temperature that sets, temp controller is promptly connected power supply, bring into operation from the temperature control electric-heating belt, when temperature transducer detects pipe temperature and is higher than the temperature that sets, temp controller is a deenergization, makes from the temperature control electric-heating belt to move under most economical rational state and satisfy the medium temperature requirement.
This circulation is carried and is had following defective:
When 1, breaking down as a certain link, the maintenance of must stopping transport of whole piece pipeline need be treated after the fault restoration could recover after the wax material that has cured in the pipeline melts again to carry, and its rate of fault is higher, and energy consumption is big, and operating cost is higher.
2, the method that adopts man-handling of materials to carry: the forfeiture of wax material temperature is big, and wax material need pass through secondary heating; Wax material transhipment course of conveying becomes easily infected by dust and other impurity, influences the wax pattern quality; Manufacturing efficiency is lower.
The model utility content
In order to overcome above-mentioned technical problem, the utility model provides a kind of conduction oil sleeve pipe, comprises thermal insulation layer, sleeve pipe, the interior bile duct of ecto-entad, and thermal insulation layer is coated on bushing outer surface, is provided with the conduction oil runner between sleeve pipe and interior bile duct.
Preferably, described interior bile duct is the interior bile duct that seamless steel pipe is made.
Preferably, described sleeve pipe is the sleeve pipe that seamless steel pipe is made.
Preferably, described thermal insulation layer is the cotton layer of glass.
Conduction oil sleeve pipe of the present utility model; interior bile duct and sleeve pipe adopt the high-quality seamless steel pipe to make; the conduction oil sleeve pipe can be welded to connect by flange and other equipment; be provided with the conduction oil runner between sleeve pipe and interior bile duct; the sleeve pipe outer rim is coated with the thermal insulation layer of the cotton layer of glass; the heat dissipation of protection conduction oil has realized that the long distance of wax liquid is carried.Through detecting on the spot, the conduction oil sleeve pipe front end and back end temperature difference is less than ± 1 ℃, and implementation result is very good.
Description of drawings:
Fig. 1 is the cross section structure figure of the utility model specific embodiment;
Among the figure: the cotton layer of 1-glass, 2-sleeve pipe, bile duct in the 3-conduction oil runner, 4-, 5-wax liquid runner.
Embodiment:
In conjunction with the accompanying drawings, below the utility model is further described.
A kind of conduction oil sleeve pipe comprises thermal insulation layer, sleeve pipe 2, the interior bile duct 4 of ecto-entad, and thermal insulation layer is coated on sleeve pipe 2 outer surfaces, and 4 in sleeve pipe 2 and interior bile duct are provided with conduction oil runner 3.The interior bile duct 4 that bile duct 4 is made for seamless steel pipe in described.The sleeve pipe 2 that described sleeve pipe 2 is made for seamless steel pipe.Described thermal insulation layer is the cotton layer 1 of glass.In the interior bile duct 4 is wax liquid runner 5, circulation wax liquid.
Conduction oil sleeve pipe of the present utility model; interior bile duct 4 and sleeve pipe 2 adopt the high-quality seamless steel pipe to make; the conduction oil sleeve pipe can be welded to connect by flange and other equipment; be provided with conduction oil runner 3 in 4 in sleeve pipe 2 and the interior bile duct; sleeve pipe 2 outer rims are coated with the thermal insulation layer of the cotton layer 1 of glass; the heat dissipation of protection conduction oil has realized that the long distance of wax liquid is carried.Through detecting on the spot, the conduction oil sleeve pipe front end and back end temperature difference is less than ± 1 ℃, and implementation result is very good.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
