Description

Technical Field

[0001] This utility model relates to the field of thermocouple processing technology, specifically a stable heating device for processing platinum-rhodium thermocouples. Background Technology

[0002] Currently, in the annealing process of platinum-rhodium thermocouple processing, researchers in related fields have developed targeted heating devices to ensure the stability of loading and unloading platinum-rhodium thermocouple workpieces. For example, patent application number 202020661198.9 discloses "a stable heating device for platinum-rhodium thermocouple processing, including an insulated box and multiple pads installed at the lower end of the insulated box. An insulated partition is vertically installed in the inner cavity of the insulated box, and the insulated partition divides the inner cavity of the insulated box into a control cavity and a heating cavity. A control component is embedded on the front wall of the insulated box corresponding to the position of the control cavity." The box body has a door on the front wall corresponding to the heating chamber, and a looped heating tube is installed on the inner wall of the heating chamber. A carrier is installed in the inner cavity of the heating chamber. After implementation, "through the combination structure of the heating tube and the carrier, the platinum-rhodium thermocouple is vertically inserted into the thermocouple slot for positioning. The sliding plate slides back and forth in the carrier slide rail. With the push and pull of the extension end of the push cylinder, the smooth output and smooth entry of the sliding plate are achieved, ensuring that the fragile platinum-rhodium thermocouple will not be damaged by the vibration caused by the movement. Combined with the looped heating tube, it can effectively ensure uniform and efficient heating of the heating chamber."

[0003] However, in actual processing, the heating temperature inside the heating device can reach thousands or hundreds of degrees Celsius. Using electric components to move and transmit the workpiece and carrier in such a high-temperature environment is too theoretical. Secondly, the existing technology mentioned above only considers the stability of entering or moving the workpiece inside the heating device during the workpiece processing, and does not consider the subsequent material transfer and rapid material change. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a stable heating device for processing platinum-rhodium thermocouples, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a stable heating device for processing platinum-rhodium thermocouples, including a heating device body, with heat-insulating and sealed cabinet doors hinged to the front and rear ends of the top of the heating device body, a heating space provided on the inner side of the top of the heating device body, a control component installed at the bottom of the heating device body, and a heating platform installed inside the heating space of the heating device body.

[0006] The front and rear ends of the bottom of the heating device body are provided with support slide rails. The top of each of the two support slide rails is movably mounted with a guide rail. Both guide rails are aligned with the heating platform, and the top of the two guide rails is provided with a guide groove. The bottom of the heating platform can be engaged in the corresponding guide groove.

[0007] Preferably, the top of the heating device body is fitted with a heating mechanism and a temperature measuring component, and there are no fewer than two heating mechanisms arranged around the heating space. The bottom inner wall of the heating space has two symmetrical combined sliding grooves.

[0008] The selected design features electromagnets mounted at both the front and rear ends of one side of each of the two supporting slide rails. The magnetic surfaces of these electromagnets can magnetically connect with the bottom surface of the guide rail. A second metal ball is mounted on the bottom of each of the two guide rails to facilitate overall movement of the guide rail.

[0009] Preferably, the heating platform includes a platform plate and two supporting slide plates. The tops of the two supporting slide plates are respectively fixedly connected to the two sides of the bottom of the platform plate, and the bottoms of the two supporting slide plates are respectively engaged in the interior of two combined sliding grooves. The top of the platform plate is provided with a clearance groove, and the bottoms of the two supporting slide plates are each fitted with a first metal ball to facilitate the overall movement of the heating platform.

[0010] Preferably, the guide grooves are set to four, and are respectively opened on both sides of the top of the two guide rails in pairs. All four guide grooves are in a through state. The four guide grooves are respectively aligned with the two combined slides in pairs to ensure the stability of the reciprocating movement of the heating platform.

[0011] The two supporting slide rails are designed with open ends away from the heating device body, providing space for the subsequent separation of the guide rail and the supporting slide rail. The ends of the two supporting slide rails near the heating device body are fixed to the front and rear ends of the bottom of the heating device body with screws, making installation and disassembly convenient.

[0012] Selectedly, both of the top sides of the guide rails are provided with threaded holes, and the threaded holes are connected to the corresponding guide grooves and threaded with long screws. The long screws can be used to press and limit the heating platform that moves onto the guide rails, thereby making the guide rails and heating platforms used as a single unit, providing convenient conditions for subsequent material conveying.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through the setting of two supporting slide rails, guide rails and electromagnet combined heating auxiliary structure, and then combined with the heating device body, heat-insulated and sealed box door, control components and heating platform, can meet the stable moving output of the entire feeding and discharging process, and solve the problems existing in the prior art.

[0015] 2. When the long screw provided in this utility model is further combined with the above-mentioned heat-assisted structure, the heating platform that has been moved to the guide rail can be re-adjusted, thereby enabling the guide rail to assist in the transport of the heating platform and expanding the overall effect of the device.

[0031] Working principle:

[0032] Example 1

[0033] During loading, the platinum-rhodium thermocouples to be processed are placed in a high-temperature resistant container. Then, the container is placed in the clearance groove on the top of the heating platform 4 until all clearance grooves are used. Next, from the front or rear of the heating device body 1, the two support slide plates 42 at the bottom of the heating platform 4 are engaged with the two guide grooves on the top of the corresponding guide rail frame 6. The heating platform 4 is pushed into the heating space inside the heating device body 1. The electromagnets 7 on the two support slide rail frames 5 are turned off. The two guide rail frames 6 are pushed away from the heating device body 1. The two heat-insulating and sealing box doors 2 are closed. The heating mechanism inside the heating device body 1 is turned on through the control component 3 to heat the platinum-rhodium thermocouples to be processed.

[0034] After heating is complete, open the two insulated and sealed boxes 2 for self-cooling. After a certain period of time, push the two guide rails 6 to reset and align with the heating device body 1. Then, activate the electromagnets 7 in the two supporting slide rails 5 to limit the displacement and reset of the guide rails 6. Next, push the heating platform 4 and select any one of the guide rails 6 for snap-fit ​​assembly until the heating platform 4 and the platinum-rhodium thermocouple treated on top of the heating platform 4 leave the heating space and detach from the corresponding guide rail 6. After the heating platform 4 detaches from the heating space, the unused guide rail 6 can be used for material loading. Repeat the above steps for subsequent operations.

[0035] Example 2

[0036] During loading, the platinum-rhodium thermocouples to be processed are placed in a high-temperature resistant container. Then, the container is placed in the clearance groove on the top of the heating platform 4 until all clearance grooves are used. Next, from the front or rear of the heating device body 1, the two support slide plates 42 at the bottom of the heating platform 4 are engaged with the two guide grooves on the top of the corresponding guide rail frame 6. The heating platform 4 is pushed into the heating space inside the heating device body 1. The electromagnets 7 on the two support slide rail frames 5 are turned off. The two guide rail frames 6 are pushed away from the heating device body 1. The two heat-insulating and sealing box doors 2 are closed. The heating mechanism inside the heating device body 1 is turned on through the control component 3 to heat the platinum-rhodium thermocouples to be processed.

[0037] After heating is complete, open the two insulated and sealed boxes 2 for self-cooling. After a certain period of time, push the two guide rails 6 to reset and connect with the heating device body 1. Then, activate the electromagnets 7 in the two support slide rails 5 to limit the displacement and reset of the guide rails 6. Next, push the heating platform 4 and select any one of the guide rails 6 for snap-fit ​​assembly. After the heating platform 4 moves to the designated position, turn the long screw 8 on the top of the guide rail 6 to squeeze and limit the heating platform 4. Then, move the guide rail 6 to detach from the support slide rails 5, and the platinum-rhodium thermocouple can be transferred. When using it again, the unused guide rail 6 can be used for loading operations at the same time as the movement begins. Then, add a new unused guide rail 6 to the corresponding support slide rail 5.
