Among them are the following problems:
1. the thermocouple is complicated and difficult to operate when being bound on the mesh belt. The iron wires penetrate through the mesh belt and then penetrate out, then the mesh belt is bound, and then the iron wires are screwed. Every thermocouple needs 3 iron wires to fix at least and just can guarantee to bind firmly, does not become flexible when the temperature measurement. Therefore, a minimum of 9 wires need to be tied up when the thermocouple is tied up. The whole process takes 5-20 minutes.
2. Thermocouples are difficult to position when binding. One of the thermocouple heads is required to be bound firstly, then the positions of the other two thermocouple heads are determined by comparing the bound one, one of the thermocouple heads is guaranteed to be in the middle of the net belt, the other 2 thermocouple heads are symmetrical on the left side and the right side, and meanwhile the 3 thermocouple heads are kept on the same transverse line, so that the temperature measured during temperature measurement is the temperature measured on the same cross section.
3. It is difficult to remove the thermocouple. When the thermocouple is out of the furnace tail, all iron wires binding the thermocouple are required to be twisted off, and the thermocouple can be pulled out of the furnace head.
4. The damage to the mesh belt and the thermocouple is great, and the service lives of the mesh belt and the thermocouple are reduced. When binding the mesh belt with the thermocouple, the wire must be screwed down, causing wear of the mesh belt, thermocouple, and resulting in reduced life.
Therefore, it is necessary to provide a method for measuring temperature of a mesh belt furnace by using an external thermocouple, which can solve at least one technical problem described above.

Detailed Description
In order to describe the technical content, the constructional features, the achieved objects and effects of the present invention in detail, the following description is made in connection with the embodiments and the accompanying drawings.
In the invention, the conveying direction of the mesh belt furnace is defined as 'front', namely the furnace tail is positioned at the front, and the furnace head is positioned at the rear during actual temperature measurement.
Referring to fig. 1 to 4, an embodiment of the invention discloses a method for measuring temperature by using an external thermocouple in a mesh belt furnace, which comprises the following steps:
101. a thermocouple mount 20 is provided.
102. The front end of the thermocouple 10 is placed on the thermocouple fixing frame 20 and fixed, and the thermocouple fixing frame 20 is placed on the mesh belt 30 positioned at the furnace end of the mesh belt furnace, and the thermocouple fixing frame 20 is combined with the mesh belt 30 through a quick-release structure. Specifically, the thermocouple assembly holder 20 is positioned in the middle of the mesh belt 30 without being skewed. It should be noted that, in order to facilitate fixing the front end of the thermocouple 10 to the thermocouple fixing frame 20, the front end of the thermocouple 10 is fixed to the thermocouple fixing frame 20 before the thermocouple fixing frame 20 is placed on the mesh belt 30, but this is not a limitation, and the present invention does not exclude the case that the thermocouple 10 is fixed to the thermocouple fixing frame 20 after the thermocouple fixing frame 20 is placed on the mesh belt 30, of course, there is no repeated operation of fixing the thermocouple 10 at the time of subsequent repeated use.
103. The thermocouple fixing frame 20 with the thermocouple 10 fixed thereto is brought into the mesh belt furnace by the operation of the mesh belt 30 and is output from the furnace tail of the mesh belt furnace.
104. The thermocouple fixing frame 20 to which the thermocouple 10 is fixed is turned over.
105. Thermocouple 10 is pulled at the burner to pull thermocouple 10 and thermocouple mount 20 from the burner.
The invention provides the thermocouple fixing frame 20 specially used for fixing the thermocouple 10, after the thermocouple 10 is fixed on the thermocouple fixing frame 20 for the first time in a binding mode and the like, the thermocouple 10 can be not detached from the thermocouple fixing frame 20 or bound again, the time for re-fixing the thermocouple 10 during each temperature measurement is saved, meanwhile, the damage of the thermocouple 10 caused by frequent fixing of the thermocouple 10 can be reduced, and the service life of the thermocouple 10 is prolonged. In addition, since the thermocouple 10 is fixed on the thermocouple fixing frame 20 for the first time by binding and other modes, frequent disassembly and re-fixing are not required normally, so before the temperature measurement, the thermocouple fixing frame 20 fixed with the thermocouple 10 is combined on the mesh belt 30 through the quick-disassembly structure, after the temperature measurement is completed, the thermocouple fixing frame 20 is output from the furnace tail, the thermocouple fixing frame 20 can be pulled out as long as the limitation of the quick-disassembly structure is released, excessive operations are not required by staff, the operation is quick and convenient, and the cost is reduced.
It will be appreciated that the thermocouple assembly holder 20 preferably has a width less than the width of the mesh belt 30 of the mesh belt furnace to facilitate smooth movement with the mesh belt 30 for temperature measurement.
Specifically, the front end of the thermocouple 10 is advanced beyond the thermocouple mount 20.
In some embodiments, the thermocouple fixing frame 20 includes a plurality of supporting bodies 21 extending substantially along the conveying direction of the mesh belt 30, and front ends of the plurality of thermocouples 10 are respectively supported on the corresponding supporting bodies 21. Of course, the thermocouple fixing frame 20 is not limited to a specific form, as long as the purpose of fixing the thermocouple 10 can be achieved.
Specifically, the support 21 is provided with a slot 22, and the front end of the thermocouple 10 is disposed in the slot 22 so as to fix the thermocouple 10.
In a specific example, the thermocouple fixing frame 20 is in a rectangular frame shape as a whole, and comprises two opposite side beams 23 and two opposite end beams 24, wherein a middle beam 25 parallel to the two side beams 23 is connected to the middle of the two end beams 24, and the two side beams 23 and the middle beam 25 are respectively used as supporting bodies 21 for supporting the thermocouples 10. The side beams 23 and the center beam 25 form a narrow groove 22, respectively, to facilitate the fixing of the thermocouple 10.
Specifically, the thermocouple 10 is fastened to the thermocouple fixing frame 20 by a wire to perform firm fixation. Compared with the prior art that the thermocouple 10 is required to be bound on the mesh belt 30 before each temperature measurement, the bound metal wires are required to be twisted off after each temperature measurement is completed, the thermocouple 10 is normally bound on the thermocouple fixing frame 20 only by one binding operation, and the thermocouple can be reused later without repeated binding and unbinding operations.
Specifically, the wire head formed when the wire is fastened is not upward, and thus can be smoothly pulled out when the thermocouple fixing frame 20 at the tail of the furnace is pulled out backward while turning over.
In some embodiments, the quick release structure is disposed on the thermocouple mount 20 and includes a plurality of downward protruding protrusions 26, and the plurality of protrusions 26 are respectively inserted into the mesh belt 30. By providing the convex part 26 which can be inserted into the mesh belt 30, the thermocouple fixing frame 20 can be positioned, which is beneficial to rapidly and stably assembling the thermocouple fixing frame 20 onto the mesh belt 30. In addition, compared with the prior method of binding the thermocouple 10 and the mesh belt 30 by utilizing iron wires, the clamping mode is beneficial to reducing damage to the mesh belt 30 and prolonging the service life of the mesh belt 30.
Specifically, at least a portion of the protrusions 26 are snapped into the mesh belt 30 by pressing down, thereby facilitating a secure coupling of the thermocouple-fixing frame 20 to the mesh belt 30. Of course, the projections 26 are not limited to necessarily be caught in the mesh belt, as long as the thermocouple-fixing frame 20 can be positioned on the mesh belt 30 substantially without relative displacement occurring when moving with the mesh belt 30.
Further, at least a portion of the protrusions 26 may be inclined backward from top to bottom (or may be inclined in other directions), and after the protrusions 26 are inserted into the mesh belt 30, the thermocouple fixing frame 20 may be pulled to determine whether the thermocouple fixing frame 20 is loose. Of course, the convex portion 26 is not limited to this configuration, as long as the purpose of positioning the thermocouple-fixing frame 20 substantially on the mesh belt 30 can be achieved.
Preferably, the thickness of the protrusions 26 is required to ensure that the protrusions 26 can be inserted into the mesh belt 30, and the number of the protrusions 26 is required to ensure that the protrusions 26 cannot be moved when pulling the thermocouple assembly holder 20 after all of the protrusions 26 are inserted into the mesh belt 30.
Of course, the quick-release structure is not limited to the specific form described above, and is only beneficial to quick assembly and removal of the thermocouple fixing frame 20, for example, the quick-release structure may also be an independent fastening part, and after the thermocouple fixing frame 20 is placed on the mesh belt 30, the thermocouple fixing frame 20 and the mesh belt 30 are fastened together by using the quick-release structure. In addition, the quick release structure may be integrally formed on the thermocouple assembly holder 20, or assembled on the thermocouple assembly holder 20, etc.
Specifically, if the thermocouple 10 is made of harder materials, when the thermocouple fixing frame 20 with the thermocouple 10 fixed thereon is turned over, the thermocouple 10 is turned over at the furnace end, so that the thermocouple 10 is prevented from driving the thermocouple fixing frame 20 to turn over and being clamped in the mesh belt furnace in the pulling process. For a relatively soft thermocouple 10, it is not necessary to simultaneously turn the thermocouple 10 around the burner.
It should be noted that the present invention can be applied to various types of thermocouples 10, such as thermocouples 10 of different lengths, thicknesses, and hardness; the thermocouple fixing frame 20 can be made of different materials, so that the thermocouple fixing frame is firm, not easy to deform and resistant to the high temperature of the mesh belt furnace; the number of thermocouples 10 that can be fixed by the thermocouple fixing frame 20 is not limited, and depends on the requirement; the structure, size, etc. of the thermocouple fixing frame 20 are not limited, and may be determined according to the width of the mesh belt 30 of the mesh belt furnace, the position to be measured, etc.
The foregoing description of the preferred embodiments of the present invention is not intended to limit the scope of the claims, which follow, as defined in the claims.
