Abstract
The utility model relates to a fixing device for temperature detection, and particularly to a thermocouple fixing device. The thermocouple fixing device comprises the thermocouple and a thermocouple sleeve. The utility model is characterized in that: a positioning barrel is sleeved on the thermocouple; a thermocouple fixing base is fixed at the top of the positioning barrel; and the positioning barrel is connected with the thermocouple sleeve through screw thread. The fixing device for temperature detection has the advantages of simple structure and convenient use. The thermocouple fixing device is suitable for measuring and fixing the constant temperature interval when reactivity and after-reaction strength test are performed for coke. The thermocouple fixing device can check the stability of temperature range at any time in the test process. Furthermore the in-time correction is facilitated for ensuring the correctness of test result.
Description
Technical field
The utility model relates to the stationary installation that a kind of temperature detection is used, specifically a kind of thermocouple fixing device.
Technical background
Commonly used to middle hot test stove in tests such as the quality testing of Inorganic Non-metallic Materials and new-product development, experiment usually requires sample to remain in a certain stationary temperature interval.Whether sample is in the temperature range of regulation, is to cause the significant effects factor of closing to the test findings accuracy.Regulation among the GB/T4000 " coke reactivity and post-reaction strength test method " for example: the length of 1100 ± 5 ℃ of temperature ranges of testing furnace is not less than 150mm, 200 ± 0.5g coke specimen under 1100 ± 5 ℃ of conditions with carbon dioxide reaction 2 hours.Carrying out in the reactivity test process in STRENGTH ON COKE, at first is to make an appointment with the particle of half to put into reactor the 200g coke specimen, inserts thermocouple sheath then, reinstall second half coke, cover chamber lid, insert thermopair, open the temperature switch board and can test.Above operation steps is: the thermocouple sheath bottom is in bed of material center, and behind the insertion thermopair, temperature controlling point is seen Fig. 1 in bed of material center.Practical situations is: testing furnace is along with the prolongation of service time, heating element can wear out, 1100 ± 5 ℃ of humidity provinces can change in the burner hearth, and causing coke specimen is not to react with carbon dioxide under 1100 ± 5 ℃ temperature range condition, influences accuracy of experimental results.General requirement can check at any time that whether coke specimen reacts with carbon dioxide, and can in time proofread and correct warranty test result's accuracy under 1100 ± 5 ℃ of temperature conditions in process of the test now.Therefore be necessary to invent a kind of thermocouple fixing device.
The utility model content
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of thermocouple fixing device is provided.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: it comprises thermopair and thermocouple sheath, it is characterized in that: be with positioning tube on the thermopair, the top of positioning tube is fixed with the thermopair holder, and positioning tube is connected with thermocouple sheath by screw thread.
The utlity model has advantage simple in structure, easy to use.It is applicable to when STRENGTH ON COKE is carried out reactivity and post-reaction strength test the mensuration between the reactor flat-temperature zone and fixing.Can check the stability of temperature range at any time in process of the test with this device, and help timely correction, warranty test result's accuracy.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 2, the utility model comprises thermopair 5 and thermocouple sheath 4, is with positioning tube 7 on the thermopair 5, and the top of positioning tube 7 is fixed with thermopair holder 6, and positioning tube 7 is connected with thermocouple sheath 4 by screw thread.
Coke carries out in the reactivity test, and coke 3 samples are put into the about 100mm of height of reactor 1, and the length of making the thermopair positioning tube can be 55mm.In the process of the test, at first reactor is all put into equably with the 200g coke specimen again in corundum ball 2 surfaces that thermocouple sheath 4 is inserted in the reactor, covers chamber lid; Then that 55mm is long positioning tube is enclosed within on the thermopair, inserts in the thermocouple sheath 4.The top of positioning tube withstands on the holder of thermopair.Opening the temperature switch board can test.From Fig. 2 as seen: thermocouple sheath bottom is in coke bed of material bottom position, load onto the long positioning tube of 55mm after, thermopair control (survey) warm spot still remains on coke bed of material center.What, can the length or the scope of temperature range be regulated, to satisfy the test demand by pack into corundum ball in the reactor of adjusting.
