Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and in particular to an ethylene glycol heat-conducting medium storage tank with a warning function. Background Technology
[0002] Ethylene glycol, a thermally conductive medium, is widely used in chemical, pharmaceutical, food processing, and precision manufacturing industries due to its excellent low-temperature fluidity, high boiling point, and stable thermal conductivity. As a core medium for heat transfer, its storage status directly affects the operational efficiency and safety of the entire production system. In practical applications, ethylene glycol is typically stored in dedicated storage tanks. Temperature control of these tanks is crucial for ensuring medium performance and avoiding safety risks. Temperature sensors and alarm devices are core components of tank temperature control, and their long-term stable operation directly determines the effectiveness of monitoring and early warning functions. However, traditional storage tanks lack convenient self-inspection and maintenance mechanisms for their core components. Verifying whether sensors are functioning correctly or alarm devices are effectively triggered often requires disassembling the equipment, interrupting normal tank operation, and performing a thorough check using external testing equipment. This process is not only complex and time-consuming but can also cause secondary damage to components due to improper disassembly and installation, increasing maintenance costs. Utility Model Content
[0003] This utility model relates to an ethylene glycol heat transfer medium storage tank with a warning function, which solves the problem that traditional storage tanks lack convenient self-inspection and maintenance mechanisms for core components such as temperature sensors and alarm devices.
[0004] This utility model provides an ethylene glycol heat-conducting medium storage tank with a warning function, specifically including: a storage tank, a monitoring shell provided below the storage tank, the top surface of the monitoring shell being fixedly connected to the bottom surface of the storage tank by a connecting column; a pressure chamber is provided inside the monitoring shell, the pressure chamber having a cylindrical cavity structure, and a sliding insertion hole penetrating the top surface of the monitoring shell is provided at the axial part of the top surface of the pressure chamber, the sliding insertion hole being a circular hole; a monitoring column of the same diameter is inserted into the sliding insertion hole, and a temperature sensor is embedded in the axial part of the top surface of the monitoring column, the temperature sensor being electrically connected to a control cabinet; an annular stop is installed on the outer circumference of the monitoring column, the annular stop being slidably inserted into the pressure chamber, and the bottom surface of the annular stop being fixedly connected to the bottom surface of the pressure chamber by a return spring; in the natural state of the return spring, the temperature sensor is in contact with the bottom surface of the storage tank.
[0005] Furthermore, a set of warning lights is fixedly installed on both the front and rear faces of the monitoring housing, and the warning lights are electrically connected to the control cabinet; when the temperature sensor detects that the temperature exceeds the specified threshold, the temperature sensor sends a feedback signal to the control cabinet, and the control cabinet controls the warning lights to start.
[0006] Furthermore, a heating on / off switch is fixedly installed on the bottom surface of the inner end of the pressure chamber. The heating on / off switch is electrically connected to the control cabinet and is a tactile switch. An electric heating element is embedded in the top surface of the monitoring column and is electrically connected to the control cabinet. When the heating on / off switch is in the pressed start state, the heating on / off switch sends a feedback signal to the control cabinet, and the control cabinet controls the electric heating element to start.
[0007] Furthermore, a rubber pressing block is fixedly installed on the bottom end face of the monitoring column; in the natural state of the reset spring, the bottom end face of the rubber pressing block is higher than the button end of the heating on / off switch.
[0008] Furthermore, a pressure groove is provided on the right side of the top surface of the monitoring housing, and the left end of the pressure groove is connected to the top right end of the pressure chamber; an electric cylinder is fixedly installed on the right side of the inner end of the pressure groove, and the electric cylinder is electrically connected to the control cabinet; a pressure ball is fixedly installed on the push rod end of the electric cylinder.
[0009] Furthermore, when the push rod end of the electric cylinder is in the unextended state, the pressure ball does not contact the top surface of the annular stop block; when the push rod end of the electric cylinder is in the extended state, the pressure ball contacts the top surface of the annular stop block, the return spring is in a compressed state, and at this time the bottom surface of the rubber pressure block contacts the button end of the heating start-stop switch, and the heating start-stop switch is in the pressed start state.
[0010] This utility model provides an ethylene glycol heat-conducting medium storage tank with a warning function, which has the following beneficial effects:
[0011] This invention utilizes the elastic force of a return spring to ensure that the temperature sensor at the top of the monitoring column remains in close contact with the bottom surface of the storage tank, directly receiving the temperature signal of the ethylene glycol heat-conducting medium transmitted through the tank wall. This avoids errors caused by environmental interference in traditional non-contact monitoring, ensuring the real-time and accurate acquisition of temperature data and providing reliable data support for the temperature control of the storage medium. Even in scenarios where the storage tank experiences slight vibration or minor installation deviations, the elastic extension and contraction characteristics of the return spring can maintain stable contact between the temperature sensor and the bottom of the tank, unaffected by fluctuations in equipment operating status, thus continuously ensuring monitoring effectiveness. When the temperature sensor detects that the tank temperature exceeds the preset safety threshold, the warning lights at the front and rear ends of the monitoring housing can be immediately triggered through the control cabinet to quickly transmit abnormal temperature information through visual light signals.
[0012] This invention utilizes the synergistic action of an electric cylinder, a pressure ball, and a heating on / off switch to periodically simulate "temperature over-limit" scenarios for self-testing of the equipment's core functions. It verifies the signal acquisition and transmission capabilities of the temperature sensor, the alarm triggering function of the warning light, and the command response logic of the control cabinet without disassembling the equipment. During the self-test, if the warning light activates normally, it indicates that the core components such as the temperature sensor, warning light, and control cabinet are all in normal working order. If the warning light is not triggered, the faulty component (such as a failed temperature sensor, a damaged warning light, or a circuit fault) can be quickly identified, reducing maintenance and troubleshooting time, lowering manual repair costs, and ensuring long-term stable operation of the equipment.

[0025] Example: Please refer to Figures 1 to 6 :
[0026] This utility model discloses an ethylene glycol heat transfer medium storage tank with a warning function, comprising: a storage tank 1, a monitoring shell 102 located below the storage tank 1, the top surface of the monitoring shell 102 being fixedly connected to the bottom surface of the storage tank 1 via a connecting column 101; a pressure chamber 104 is provided inside the monitoring shell 102, the pressure chamber 104 having a cylindrical cavity structure, and a sliding insertion hole 107 penetrating the top surface of the monitoring shell 102 is provided at the axial position of the top surface of the pressure chamber 104, the sliding insertion hole 107 being a circular hole; a monitoring column 3 of the same diameter is inserted into the sliding insertion hole 107, and a temperature sensor 304 is embedded in the axial position of the top surface of the monitoring column 3. 304 is electrically connected to the control cabinet; an annular stop 301 is installed on the outer circumference of the monitoring column 3, and the annular stop 301 is slidably inserted into the pressure chamber 104. The bottom end of the annular stop 301 is fixedly connected to the bottom end of the pressure chamber 104 by a return spring 302; in the natural state of the return spring 302, the temperature sensor 304 is in contact with the bottom end of the storage tank 1; a set of warning lights 103 are fixedly installed on the front and rear ends of the monitoring housing 102, and the warning lights 103 are electrically connected to the control cabinet; when the temperature sensor 304 senses a temperature exceeding the specified threshold, the temperature sensor 304 sends a feedback signal to the control cabinet, and the control cabinet controls the warning lights 103 to start.
[0027] A heating switch 105 is fixedly installed on the bottom surface of the inner end of the pressure chamber 104. The heating switch 105 is electrically connected to the control cabinet and is a tactile switch. An electric heating element 305 is embedded in the top surface of the monitoring column 3 and is electrically connected to the control cabinet. When the heating switch 105 is in the pressed-on state, it sends a feedback signal to the control cabinet, which then controls the electric heating element 305 to start. A rubber pressure block 303 is fixedly installed on the bottom surface of the monitoring column 3. In the natural state of the return spring 302, the bottom surface of the rubber pressure block 303 is higher than the button end of the heating switch 105. A pressure block is provided on the right side of the top surface of the monitoring housing 102. The left end of the groove 106 is connected to the top right end of the pressure chamber 104; an electric cylinder 2 is fixedly installed on the right side of the inner end of the pressure groove 106, and the electric cylinder 2 is electrically connected to the control cabinet; a pressure ball 201 is fixedly installed on the push rod end of the electric cylinder 2; when the push rod end of the electric cylinder 2 is in the non-extended state, the pressure ball 201 does not contact the top surface of the annular stop block 301; when the push rod end of the electric cylinder 2 is in the extended state, the pressure ball 201 contacts the top surface of the annular stop block 301, the return spring 302 is in the compressed state, and at this time the bottom surface of the rubber pressure block 303 contacts the button end of the heating start-stop switch 105, and the heating start-stop switch 105 is in the pressed start state.
[0028] The working principle of this embodiment:
[0029] In daily use, when the return spring 302 is in its naturally extended state, its upward elastic force is transmitted to the monitoring column 3 through the annular stop 301, so that the temperature sensor 304 embedded in the top of the monitoring column 3 is in close contact with the bottom surface of the storage tank 1. Since the temperature of the ethylene glycol heat-conducting medium will be conducted to the bottom of the tank through the wall of the storage tank 1, the temperature sensor 304 can directly and in real time collect the actual temperature data of the storage tank 1 and transmit the data synchronously to the control cabinet.
[0030] The control cabinet has a preset safe temperature threshold for ethylene glycol as the heat-conducting medium. When the temperature data collected by the temperature sensor 304 exceeds this threshold, the temperature sensor 304 immediately sends an over-limit signal to the control cabinet. After receiving the signal, the control cabinet automatically triggers the warning lights 103 on the front and rear ends of the monitoring housing 102 to activate, providing a visual warning by flashing or remaining constantly lit, reminding staff to promptly investigate the cause of the abnormal temperature and avoid equipment damage or safety risks caused by abnormal temperatures.
[0031] To ensure that core components such as temperature sensor 304 and warning light 103 are in normal working condition for a long time, regular maintenance and self-inspection are required. The operator sends an extension command to electric cylinder 2 through the control cabinet. The push rod end of electric cylinder 2 extends outward, pushing the pressure ball 201 at its end to move to the left. After the pressure ball 201 contacts the top surface of the annular stop block 301, it continuously applies downward pressure, forcing the annular stop block 301 to compress the return spring 302 and drive the monitoring column 3 to move downward along the sliding insertion hole 107 until the temperature sensor 304 at the top of the monitoring column 3 is completely separated from the bottom surface of the storage tank 1, cutting off the temperature sensor 304's acquisition of the actual temperature of the storage tank 1. As the monitoring column 3 moves downward, the rubber pressure block 303 at its bottom moves downward synchronously, eventually contacting and pressing the button end of the heating on / off switch 105 at the bottom of the pressure chamber 104. After the heating on / off switch 105 is pressed and activated, it immediately sends a trigger signal back to the control cabinet; the control cabinet receives... Upon receiving the signal, the electric heating element 305 embedded in the top of the automatic control monitoring column 3 is activated. The electric heating element 305 heats up and simulates the high temperature state of the storage tank 1, causing the ambient temperature around the temperature sensor 304 to rise rapidly to the preset over-limit threshold. If the temperature sensor 304 is working normally, it will collect the "high temperature signal" simulated by the electric heating element 305 in real time and transmit it to the control cabinet. After the control cabinet receives the "high temperature signal", if it can trigger the warning light 103 to start normally, it means that the signal acquisition and transmission function of the temperature sensor 304 and the alarm function of the warning light 103 are both in normal condition. If the warning light 103 is not triggered, it can be determined that the temperature sensor 304 or the warning light 103 is faulty and needs further inspection and maintenance. After the self-test is completed, the control cabinet controls the electric cylinder 2 push rod end to retract, the reset spring 302 returns to its natural state, the monitoring column 3 moves up so that the temperature sensor 304 re-attaches to the bottom surface of the storage tank 1, and the equipment returns to the daily monitoring state.
