Description

Technical Field

[0001] This utility model relates to the field of temperature control instrument technology, and in particular to a temperature control instrument for a thermocouple calibration furnace. Background Technology

[0002] Thermocouple calibration furnace temperature controller is a device used for precise control and regulation of the temperature inside a thermocouple calibration furnace. It monitors the furnace temperature in real time using a temperature sensor and, combined with an advanced fuzzy PID control algorithm, rapidly adjusts the power of the heating elements to ensure the furnace temperature remains stable at the set value. This controller features temperature profile setting, automatic calibration, and touchscreen operation. It is suitable for thermocouple calibration, verification, and testing. Its high precision and rapid response characteristics make it widely used in industrial temperature measurement, laboratory research, and metrological verification, ensuring the accuracy and reliability of thermocouple measurements.

[0003] A search revealed a thermocouple calibration furnace temperature controller circuit (authorization announcement number: CN 203276054 U). The circuit comprises a 24V DC power supply, a relay, a temperature controller TC, and a solid-state relay (SSR). Based on temperature control principles, it utilizes a digital temperature display, a 24V DC power supply, and advanced high-precision digital temperature control instruments. PID automatic adjustment of the temperature rise curve ensures smooth temperature increase without overheating. Furthermore, the use of an SSR solid-state relay as the control element enhances the safety of the experimental equipment.

[0004] Based on the aforementioned technologies, the applicant believes that existing thermocouple calibration furnace temperature controllers are mostly directly fixed on the thermocouple calibration furnace, and the remote control cannot be removed, making remote operation impossible. This has certain shortcomings in actual use. However, in response to the above problems, we have introduced a thermocouple calibration furnace temperature controller. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] The thermocouple calibration furnace temperature controller disclosed in this utility model is mainly used in temperature controller scenarios.

[0032] Reference Figure 1 - Figure 7A temperature controller for a thermocouple calibration furnace includes a calibration furnace body 1. A mounting slot 5 is provided on the top of the calibration furnace body 1. A temperature controller 6 is installed inside the mounting slot 5. The temperature controller 6 has a built-in infrared remote control module, which can remotely control the calibration furnace body 1. An installation mechanism is provided on the top of the calibration furnace body 1. The installation mechanism includes a first fixing component and a second fixing component, which cooperate with each other. The first fixing component includes a buckle 71, which is fixedly connected to the inner wall of the mounting slot 5. On one side, the interior of the main body 1 of the calibration furnace has an elastic groove 72. A slide rod 73 is slidably connected inside the elastic groove 72. A spring 74 is sleeved on the outside of the slide rod 73. A limiting plate 75 is fixedly connected to the outside of the slide rod 73. One end of the slide rod 73 extends into the interior of the placement slot 5 and is fixedly connected to a fixing ball 76. One end of the temperature controller 6 has an annular groove 710. The annular groove 710 and the fixing ball 76 cooperate with each other. The other end of the temperature controller 6 has a locking groove 711. The locking groove 711 and the buckle 71 cooperate with each other. The second fixing component includes a support strip 77. The support strip 77 is fixedly connected at equal intervals to the bottom of the inner wall of the placement slot 5. L-shaped locking grooves 78 are opened on both sides of the inner wall of the placement slot 5. Limiting rods 79 are symmetrically fixedly connected to the outside of the temperature controller 6. The size of the limiting rods 79 matches the size of the L-shaped locking grooves 78. The limiting rods 79 and the L-shaped locking grooves 78 cooperate with each other.

[0033] In this embodiment: In actual use, the operator first powers on the main body 1 of the calibration furnace, and the main body 1 of the calibration furnace starts to work. When it is necessary to remove the temperature controller 6 for remote adjustment, the operator pulls the temperature controller 6 by hand, so that the temperature controller 6 slides inside the mounting slot 5 until the buckle 71 is completely disengaged from the slot 711. At this time, the limiting rod 79 slides inside the L-shaped slot 78 towards the elastic groove 72, and the sliding rod 73 slides, driving the limiting plate 75 to compress the spring 74. When the temperature controller 6 can no longer be pushed, the operator rotates the temperature controller 6 upwards, and the temperature controller 6 can be removed from the inside of the mounting slot 5. Through the set installation mechanism, the temperature controller 6 can be quickly disassembled and assembled. The temperature controller 6 can remotely adjust the temperature of the main body 1 of the calibration furnace, which greatly improves the operator's operating efficiency. The structure is simple and the practicality is strong.

[0034] In the above technical solution, considering that the existing temperature controllers for thermocouple calibration furnaces are mostly directly fixed on the thermocouple calibration furnace, and the remote control cannot be removed and cannot be remotely operated, there are still some shortcomings in actual use. In order to solve these problems, the specific operation is as follows:

[0035] Reference Figure 1 - Figure 7In a preferred embodiment, a stabilizing frame 8 is fixedly connected to the back of the testing furnace body 1. A protective silicone pad 9 for cushioning is fixedly connected to the bottom of the testing furnace body 1 and the stabilizing frame 8. A touch screen 2 is provided on the front of the testing furnace body 1, and a control area 3 is provided on the front of the testing furnace body 1 and below the touch screen 2. A connection port 4 is provided on the back of the testing furnace body 1. Heat dissipation grooves 10 are equidistantly provided on both sides of the testing furnace body 1 for heat dissipation.

[0036] In this embodiment, the addition of a stabilizing frame 8 and protective silicone pads 9 enhances the overall stability of the equipment, reduces vibration and noise, and extends its service life. The heat dissipation groove 10 effectively improves the equipment's heat dissipation performance, ensuring stable operation in high-temperature environments. The rear connection port 4 facilitates functional expansion, making it suitable for industrial and laboratory scenarios requiring high-precision temperature control. The overall design balances efficiency, stability, and ease of maintenance, meeting the high-precision temperature control requirements of the calibration furnace body 1.

[0037] Working principle: In actual use, the operator first powers on the main body 1 of the calibration furnace, and the main body 1 of the calibration furnace starts to work. When it is necessary to remove the temperature controller 6 for remote adjustment, the operator pulls the temperature controller 6 by hand, so that the temperature controller 6 slides inside the mounting slot 5 until the buckle 71 is completely disengaged from the slot 711. At this time, the limit rod 79 slides inside the L-shaped slot 78 towards the elastic groove 72, and the slide rod 73 slides, which drives the limit plate 75 to compress the spring 74. When the temperature controller 6 can no longer be pushed, the operator rotates the temperature controller 6 upwards, and the temperature controller 6 can be removed from the inside of the mounting slot 5. Then the temperature of the main body 1 of the calibration furnace can be remotely adjusted.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
