Description

Technical Field

[0001] This utility model relates to the field of heater technology, and more specifically to a heater temperature monitoring and protection device. Background Technology

[0002] Temperature monitoring and protection are crucial in the operation of heaters. Through the precise cooperation of temperature controllers and thermocouples, the heater temperature is monitored in real time to ensure safe operation and provide reliable temperature protection for the heater, thus guaranteeing production efficiency and product quality.

[0003] The existing thermocouple probes used for temperature monitoring and protection are prone to tilting and leaking after being inserted into the temperature sensing hole of the heater due to the difference between the hole diameter and the probe diameter. This results in poor sealing, allowing external air to enter the heater and affecting the accuracy of temperature monitoring. Therefore, a heater temperature monitoring and protection device is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a heater temperature monitoring and protection device, which provides a temperature detection and protection device with high stability for the heater. It can ensure that after the thermocouple probe is inserted into the temperature detection hole of the heater, the thermocouple probe and the temperature detection hole of the heater can be stably fixed and will not be skewed or leak. Especially for heaters with a certain pressure inside, it can prevent the entry of external air and the resulting impact on the accuracy of temperature monitoring.

[0005] The technical solution adopted by this utility model to solve its technical problem is a heater temperature monitoring and protection device, including a temperature controller and a thermocouple. The output end of the thermocouple and the input end of the temperature controller are electrically connected by a wire. A movable flange is fitted on the probe of the thermocouple. A first rubber ring for increasing the friction between the movable flange and the probe of the thermocouple is connected to the top of the movable flange. An increasing component is connected to one side of the top of the movable flange.

[0006] By adopting the above technical solution, a temperature detection and protection device with high stability is provided for the heater through a mechanism composed of a temperature controller, thermocouple, and additional components. This device ensures that after the thermocouple probe is inserted into the temperature detection hole of the heater, the probe is stably fixed to the temperature detection hole of the heater without tilting or leaking. Especially for heaters with a certain pressure inside, this device can prevent external air from entering and affecting the accuracy of temperature monitoring.

[0007] Specifically, a lower guide sleeve is provided at the bottom center of the movable flange, and a second rubber ring with a hollow air cavity is fitted around the outer periphery of the lower guide sleeve. At least one set of the second rubber ring is provided, and the inner periphery of the second rubber ring is adhered and fixed to the outer periphery of the lower guide sleeve.

[0008] By adopting the above technical solution and setting the second rubber ring, the sealing performance between the movable flange and the thermocouple probe can be improved.

[0009] Specifically, the added components include a piston sleeve, a piston head, an internal threaded sleeve, and a threaded rod. The bottom of the piston sleeve is fixedly connected to the movable flange. The bottom of the piston sleeve is connected to the first rubber ring and the second rubber ring through a pipe and communicates with the hollow inflation chambers of the first rubber ring and the second rubber ring.

[0010] The installation of a second rubber ring improves the sealing between the movable flange and the temperature monitoring port of the heater.

[0011] Specifically, the internal threaded sleeve is fixedly connected to the top of the piston sleeve, the piston head is located inside the piston sleeve, the threaded rod is threadedly inserted into the internal threaded sleeve, and the bottom of the threaded rod is fixedly connected to the center of the top of the piston head.

[0012] Specifically, a knob is connected to the top of the threaded rod.

[0013] By adopting the above technical solution, through the setting of the piston head and knob, after the operator rotates the knob, the threaded rod at the bottom of the knob, based on the threaded connection with the inner threaded sleeve, will drive the piston head to rise or fall in the piston sleeve, so that the air in the piston sleeve can be pushed out into the first rubber ring and the second rubber ring, causing the first rubber ring and the second rubber ring to expand, thereby further improving the sealing effect between the movable flange and the thermocouple probe and the temperature monitoring hole of the heater used in conjunction, and preventing the exchange of air inside and outside the heater.

[0014] The beneficial effects of this utility model are as follows: Through a mechanism composed of a temperature controller, thermocouple, and additional components, a highly stable temperature detection and protection device is provided for the heater. This ensures that after the thermocouple probe is inserted into the heater's temperature detection hole, it is stably fixed and will not skew or leak. Especially for heaters with internal pressure, this prevents external air from entering and affecting the accuracy of temperature monitoring, thus ensuring the reliability of the heater's temperature monitoring and protection. This solves the problem that in existing temperature monitoring and protection devices, the thermocouple probe, due to a difference in diameter between the hole and the probe, is easily skewed and leaks after insertion, resulting in poor sealing and allowing external air to enter the heater, affecting the accuracy of temperature monitoring.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6 As shown, the heater temperature monitoring and protection device of this utility model includes a temperature controller 1 and a thermocouple 2. The output end of the thermocouple 2 is electrically connected to the input end of the temperature controller 1 through a wire. A movable flange 21 is fitted on the probe of the thermocouple 2. A first rubber ring 211 is connected to the top of the movable flange 21 to increase the friction between the movable flange 21 and the probe of the thermocouple 2. An increasing component 22 is connected to one side of the top of the movable flange 21.

[0025] The present invention also includes a lower guide sleeve 23 disposed at the bottom center of the movable flange 21, and a second rubber ring 24 having a hollow air cavity inside is sleeved on the outer periphery of the lower guide sleeve 23. At least one set of the second rubber ring 24 is provided, and the inner periphery of the second rubber ring 24 is adhered and fixed to the outer periphery of the lower guide sleeve 23.

[0026] When in use, the second rubber ring 24 improves the sealing between the movable flange 21 and the probe of the thermocouple 2.

[0027] The present invention also includes that the additional component 22 includes a piston sleeve 221, a piston head 224, an internal threaded sleeve 222 and a threaded rod 223. The bottom of the piston sleeve 221 is fixedly connected to the movable flange 21. The bottom of the piston sleeve 221 is connected to the first rubber ring 211 and the second rubber ring 24 through a pipe and communicates with the hollow air-filled cavities of the first rubber ring 211 and the second rubber ring 24.

[0028] The installation of the second rubber ring 24 improves the sealing between the movable flange 21 and the temperature monitoring hole of the heater.

[0029] The present invention further includes that the internal threaded sleeve 222 is fixedly connected to the top of the piston sleeve 221, the piston head 224 is located inside the piston sleeve 221, and the threaded rod 223 is threadedly inserted into the internal threaded sleeve 222, and the bottom of the threaded rod 223 is fixedly connected to the center of the top of the piston head 224.

[0030] This utility model also includes a knob 225 connected to the top of the threaded rod 223.

[0031] In use, by utilizing the piston head 224 and the knob 225, after the operator rotates the knob 225, the threaded rod 223 at the bottom of the knob 225, based on its threaded connection with the inner threaded sleeve 222, will drive the piston head 224 to rise or fall in the piston sleeve 221. This allows the air in the piston sleeve 221 to be pushed out into the first rubber ring 211 and the second rubber ring 24, causing the first rubber ring 211 and the second rubber ring 24 to expand. This further improves the sealing effect between the movable flange 21 and the probe of the thermocouple 2 and the temperature monitoring hole of the heater used in conjunction with it, thus preventing the exchange of air inside and outside the heater.

[0032] Furthermore, the first rubber ring 211 and the second rubber ring 24 are identical in structure except for their diameters, and the diameter of the first rubber ring 211 is smaller than the diameter of the second rubber ring 24.

[0033] In use, the thermostat 1 is connected to the leakage protection device and AC contactor on the heater via wires. The probe of the thermocouple 2 is then inserted into the temperature detection hole of the heater. Rotating the knob 225 causes the threaded rod 223 at the bottom of the knob 225 to move the piston head 224 up or down within the piston sleeve 221, based on its threaded connection to the inner threaded sleeve 222. This pushes air out of the piston sleeve 221 into the first rubber ring 211 and the second rubber ring 24, causing them to expand. This compresses the probe of the thermocouple 2, allowing it to contact the temperature detection hole of the heater. Maintaining a certain verticality between the measuring holes effectively prevents the thermocouple 2 from tilting, improves the sealing effect between the movable flange 21, the probe of the thermocouple 2, and the temperature monitoring hole of the heater used in conjunction with it, avoids air exchange between the inside and outside of the heater, ensures the accuracy of temperature detection and the stability of the heater's internal operation, and transmits the detected temperature signal from the thermocouple 2 to the temperature controller 1. The temperature controller 1 compares the received temperature signal with the temperature set by the user and outputs a corresponding control signal. The AC contactor controls the power supply to the heater according to the control signal of the temperature controller, realizing the temperature monitoring and protection of the heater.
