Abstract
The utility model provides a novel thermocouple which can measure the temperature of kilns, and can especially measure the temperature of rotary kilns. The utility model is composed of a protective tube, thermocouple wires, a heat transferring member, filling thermal insulation material, a binding post, a protective cover, etc. Compared with the common thermocouple, the utility model is characterized in that the heat transferring member additionally welded at the front end of the thermocouple wires can postpone the damage time of a temperature measuring head under the action of the impact and the friction of material. Thereby, the service life can be extended. The timely accurate long-term continuous on-line measurement of the temperature of the kilns provides technical guarantee value.
Description
The present invention relates to a kind of device of measuring kiln temperature, especially can be used for a kind of New-type thermocouple that kiln temperature is measured preferably.
In measuring the kiln temperature technology, kiln temperature is measured and is adopted ordinary hot galvanic couple prior art to carry out, and the ordinary hot galvanic couple is inserted detect kiln temperature in the body of heater.Since the rotary kiln body constantly rotate and kiln in material carrying out as spiral, can make the ordinary hot galvanic couple that inserts in the body of heater be subjected to the collision friction of material, thereby cause the temperature measuring head damage of thermopair and lose the thermometric effect, this brings very big difficulty with automatic control for on-the-spot data acquisition and temperature online forecast.
At the problem that above-mentioned common thermocouple measurement kiln temperature prior art exists, the invention provides a kind of measurement kiln temperature and measure, particularly the New-type thermocouple of kiln temperature measurement.It can improve serviceable life, guarantees promptly and accurately to detect kiln temperature, has created condition for realizing long-term temperature measurement on-line, thereby solves common thermocouple measurement kiln temperature the deficiencies in the prior art.
The present invention realizes by the structure that changes the thermocouple temperature measurement head.With ordinary hot galvanic couple difference; the galvanic couple silk front end that is New-type thermocouple of the present invention welds a heat transfer piece, to delay the damage time of temperature measuring head under material collision friction effect, in addition; thermocouple wire and heat transfer piece are added with a protection tube outward, fill up insulation material in the pipe.Also be added with a protective cover at a end, whole device is protected, prevent to damage, to increase the service life by the thermopair binding post.
Below in conjunction with accompanying drawing and manufacture and require that the present invention will be further described.Fig. 1 is the structural drawing of New-type thermocouple of the present invention.As shown in Figure 1, part 1 is a protection tube, and part 2 is a thermocouple wire, and part 3 is a heat transfer piece, and part 4 is the filling insulation material, and part 5 is a binding post, and part 6 is a protective cover, and whole New-type thermocouple is made of these 6 parts.Wherein part 1 protection tube is guard member 2 thermocouple wires and part 3 heat transfer pieces, and its length is according to thermometric and installation requirement design, but diameter can not be too little, in order to avoid influence measuring accuracy; Part 2 thermocouple wires are selected suitable material according to temperature needs to be measured, and available nickel chromium triangle or nickel alumin(i)um alloy etc. are made; Part 3 heat transfer pieces, one end and thermocouple wire front end weld, the other end can contact with tested atmosphere, its transversal section is circular or square and other shapes, and its length, sectional area and manufacture material and take all factors into consideration definite according to temperature to be measured and the requirements such as sensitivity and precision estimated, the general little material of heat conduction good specific heat of selecting, length can not be long, in order to avoid desensitization; Part 4 filling insulation materials are packed in the protection pipe fitting 1 uniformly also to be decided according to temperature to be measured, to select fibrous material the best.
New-type thermocouple of the present invention is when implementing the kiln temperature detection, one end of heat transfer piece 3 contacts with tested atmosphere, and the other end is passed to thermocouple wire with temperature signal, and then the temperature signal that thermocouple wire is drawn is mended taste processing, guarantee the stability of signal with this, improve the precision of measuring.Still to utilize the temperature effect of galvanic couple silk to carry out the principle of temperature detection identical with the ordinary hot galvanic couple for its measuring principle.
Compare with existing common thermocouple, the significant advantage of New-type thermocouple of the present invention is that the thermocouple wire front end newly adds The heat transfer piece 3 of weldering can prolong its service life, for promptly and accurately and long-term continuous on-line detection kiln temperature provide Technical guarantee is a kind of New-type thermocouple with practical value.
Claims (3)
1, a kind of New-type thermocouple; constitute by 6 parts such as protection tube, thermocouple wire, heat transfer piece, filling insulation material, binding post and protective covers; it is characterized in that having one one end and the heat transfer piece that the welding of thermocouple wire front end, the other end can contact with tested atmosphere, the insulation material of even filling is arranged in protection tube.
2, by the described New-type thermocouple of claim 1, the transversal section that it is characterized in that heat transfer piece also can be square or other shape for circular, manufactures material and adopts the little material of heat conduction good specific heat.
