Description
Technical field
The utility model relates to the thermometric frock in aluminum alloy melt casting process, is specifically related to a kind of portable thermal couple.
Background technology
In aluminum alloy melt casting is produced, measurement and the control of temperature can reduce scaling loss, ensure product quality.In aluminum alloy melt casting process, usually use portable thermal couple as shown in Figure 1 to carry out thermometric; this portable thermal couple is very elongated, inconvenient to thermopair brushing protective coating, and during thermometric, thermopair contact aluminium liquid is easily corroded; serviceable life is shorter, adds production cost.General about the 6-10mm of portable thermoelectric dual diameter simultaneously, easily bending, kinking after being heated, the alumite on thermopair is difficult to cleaning.Use and be inconvenient to deposit and easily affect measuring accuracy afterwards.
Summary of the invention
The purpose of this utility model proposes a kind of portable thermal couple, can quick temperature measurement, and safeguard, easy maintenance, long service life.
A kind of portable thermal couple described in the utility model, comprises handle, and one end of described handle is connected with temperature indicator, and its other end is fixed with thermopair, and the outer of described thermopair is arranged with sleeve pipe; The rear end of sleeve pipe is connected with described handle, and the front end of sleeve pipe is provided with through hole close-fitting with described thermopair, and described through hole is passed as contact site in the front end of described thermopair; The internal diameter of described sleeve pipe is greater than the external diameter of described thermopair, and the front portion of described sleeve pipe and the front portion of described thermopair are bent to form bending part simultaneously, and the front end of described sleeve pipe has been provided with flame retardant coating to the inner chamber between described bending part.
Adopt such scheme, in use convenient in carrying, strong adaptability, deposit conveniently.Sleeve pipe is arranged with at the outer of thermopair; prevent aluminium liquid in thermometric process from corroding the thermopair in sleeve pipe; the effect that sleeve pipe plays protection to thermopair and strengthens, avoids other parts of thermopair to contact with aluminium liquid, protects thermopair in use not produce the phenomenons such as bending, bending.During thermometric, thermopair only needs very short part (contact site) to contact with aluminium liquid, facilitates brushing protective coating before measurement, the alumite after measuring on easy cleaning thermopair, and deposits conveniently.
Further, the outer wall of described sleeve pipe is coated with the protective seam be made up of boron nitride or talcum powder.
Further, the diameter of described sleeve pipe is 3 to 5 times of the diameter of described thermopair, and the cavity of inside pipe casing is comparatively large, for thermopair provides better protective effect.
Further, described flame retardant coating is made up of asbestos or fire clay, when the front portion of sleeve pipe contacts with aluminium liquid, plays heat insulation effect, protection thermopair.
Further, described sleeve pipe is iron pipe or steel pipe, and this sleeve pipe cost is low.
Further, the length of described contact site is 80mm, ensures that thermopair fully contacts with aluminium liquid, has higher temperature measurement accuracy.
The utility model is arranged with sleeve pipe at the outer of thermopair, and the outer wall of sleeve pipe is coated with the protective seam be made up of boron nitride or talcum powder, and protection thermopair, not by aluminium corrosion, also can prevent thermopair Yin Gaowen in use procedure and bend.And casing diameter is comparatively large, convenient by holding, make to be coated with protective coating at contact site very convenient, contribute to the alumite clearing up contact site after a procedure simultaneously.Extend the serviceable life more than 4 times of thermopair.
Accompanying drawing explanation
Fig. 1 is the structural representation of former portable thermal couple;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of portable thermal couple as shown in Figure 2, comprise handle 7, one end of handle 7 is connected with temperature indicator 1, its other end is fixed with thermopair 3, the outer of thermopair 3 is arranged with the sleeve pipe 4 be made up of iron pipe or steel pipe, the outer wall of sleeve pipe 4 is coated with the protective seam be made up of boron nitride or talcum powder, and the internal diameter of sleeve pipe 4 is greater than the external diameter of thermopair 3, and the diameter of concrete sleeve pipe 4 is 3 to 5 times of the diameter of thermopair 3; The rear end of sleeve pipe 4 is connected with handle 7, and the front end of sleeve pipe 4 is provided with through hole close-fitting with thermopair 3, and through hole is passed as contact site 6 in the front end of thermopair 3, and makes encapsulation process in through hole, and the length of contact site 6 is 80mm; The front portion of sleeve pipe 4 and the front portion of thermopair 3 are bent to form bending part 8 simultaneously, and the front end of sleeve pipe 4 has been provided with flame retardant coating 5 to the inner chamber between bending part 8, and flame retardant coating 5 is made up of asbestos or fire clay.
Portable thermal couple described in the utility model in use, is first coated protective coating at the outer wall of contact site 6, is then stretched in aluminium liquid 2 down by contact site 6, carry out reading after 6-10mm by temperature indicator 1.The utility model convenient in carrying, long service life.
