Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to an explosion-proof heater with automatic temperature regulation function. Background Technology

[0002] An explosion-proof heater is a device used for safe heating in hazardous environments containing flammable and explosive gases, dust, etc. Through special design and manufacturing, it ensures that no sparks, high temperatures, or other dangerous factors that could cause an explosion are generated during the heating process.

[0003] An explosion-proof heater consists of a heating element, a housing, a junction box, a temperature control system, insulation materials, seals, and an overload protection device. Temperatures vary in different locations within the explosion-proof heater, and a single monitoring device cannot effectively control the overall temperature of the heater, which can easily lead to unstable temperature control and an inability to quickly and accurately maintain the heater temperature within a safe range in hazardous environments.

[0004] To address these issues, those skilled in the art have proposed an explosion-proof heater with automatic temperature regulation to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problem that the temperature of different parts of the explosion-proof heater varies in the above or existing technologies, and that a single monitoring device cannot effectively control the temperature of the entire explosion-proof heater, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an explosion-proof heater with automatic temperature regulation function.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an explosion-proof heater with automatic temperature regulation function, including a base, on which an outer shell is disposed, the base and the outer shell serving as the supporting foundation for the entire explosion-proof heater;

[0009] A heat exchange mechanism is provided on the outer casing;

[0010] A heating mechanism is disposed above the base;

[0011] A temperature warning mechanism is connected to the heating mechanism to monitor the temperature of the heating mechanism in real time, and disconnects the switch of the explosion-proof heater when the temperature is abnormal.

[0012] A heat transfer mechanism is mounted on the heat exchange mechanism, with one end extending into the interior of the heat exchange mechanism;

[0013] A temperature monitoring mechanism installed on the outer casing is connected to the heat transfer mechanism and is used to monitor the heat transfer mechanism in real time and display the temperature data.

[0014] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the heating mechanism includes a base plate, on which multiple electric heaters are vertically installed in a ring-shaped arrangement.

[0015] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the heat transfer mechanism includes a pump body, which is installed on the bottom inner wall of the heat exchange mechanism. Multiple pipes are installed in a ring on the outer wall of the pump body. The pipes are located outside the electric heater, and one end of the pipes leads to the interior of the heat exchange mechanism.

[0016] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the temperature warning mechanism is multiple, and the temperature warning mechanism includes a thermally conductive silicone grease sleeve and a copper shell. The copper shell is installed on the surface of the base plate, and the copper shell and the corresponding electric heater are sleeved on the inner wall of the same thermally conductive silicone grease sleeve.

[0017] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, wherein: a piston is slidably arranged in the middle of the inside of the copper shell, the cavity formed by the bottom of the piston and the copper shell is filled with hydraulic oil, a fixing rod is installed on the surface of the piston, and a start / stop button is provided on the top inner wall of the copper shell.

[0018] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the heat exchange mechanism includes a heat exchanger, which is installed on the surface of the outer shell, and one end of the pipeline leads to the interior of the heat exchanger.

[0019] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, a temperature sensor is installed on the outer wall of the heat exchanger, a fixing base is provided on the outer wall of the heat exchanger, and a temperature display is installed on the surface of the fixing base.

[0020] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the temperature monitoring mechanism includes a mounting base and two temperature sensors. One end of each of the two temperature sensors is connected to the interior of the corresponding pipeline. The main body of the temperature sensor is located on the outside of the outer shell. The mounting base is installed on the outer wall of the outer shell. Temperature display instrument one and temperature display instrument two are mounted on the surface of the mounting base.

[0021] As a preferred embodiment of the explosion-proof heater with automatic temperature regulation function of this utility model, the mounting base is equipped with a controller, and both ends of the electric heater are provided with thyristors. The controller controls the power of the electric heater through the thyristors according to the temperatures of the temperature display instrument 1 and the temperature display instrument 2.

[0022] The beneficial effects of this explosion-proof heater with automatic temperature regulation function are as follows: Since heat will be lost during the transfer process, this device monitors the temperature at three locations: the electric heater, the pipeline, and the heat exchanger. This makes it easier to know the temperature at each location inside the explosion-proof heater, thus facilitating the control of the explosion-proof heater.

[0023] Temperature sensors, temperature display unit 1, and temperature display unit 2 are used to monitor the temperature of two pipelines. This avoids errors in the detection results and monitors the initial temperature of the medium inside the pipeline after it is heated. If the temperature is too high, the controller uses a thyristor to control the power of the electric heater. In an AC circuit, by controlling the conduction angle of the thyristor, the proportion of time it conducts within one cycle can be controlled. When the conduction angle of the thyristor increases, the time for the electric heater to receive voltage within one cycle becomes longer, the average voltage increases, and the power also increases, resulting in more heat generated by the electric heater. Conversely, when the conduction angle decreases, the average voltage across the electric heater decreases, the power decreases, and the heat generated decreases. This allows for the regulation of the electric heater's power, thereby controlling the heating temperature.

[0024] The temperature warning mechanism monitors the initial maximum temperature of the heating mechanism after heating. If the temperature is too high and exceeds the warning value, the device will stop when the start / stop button is touched by the fixed rod. Attached Figure Description

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an explosion-proof heater with automatic temperature adjustment function, which can realize the effect of detecting the temperature of multiple points inside the explosion-proof heater. It includes a base 100, and an outer shell 101 is provided on the base 100. The base 100 and the outer shell 101 serve as the supporting foundation for the entire explosion-proof heater.

[0036] Heat exchange mechanism 200 is provided on the outer casing 101;

[0037] Heating mechanism 300 is located above base 100;

[0038] Temperature warning mechanism 400 is connected to heating mechanism 300 to monitor the temperature of heating mechanism 300 in real time. When the temperature is abnormal, the switch of explosion-proof heater is disconnected.

[0039] A heat transfer mechanism 500 is installed on a heat exchange mechanism 200, with one end extending into the interior of the heat exchange mechanism 200;

[0040] The temperature monitoring mechanism 600, which is installed on the outer casing 101, is connected to the heat transfer mechanism 500 and is used to monitor the heat transfer mechanism 500 in real time and display the temperature data.

[0041] In use, the heating mechanism 300 is activated to heat the device. The heating mechanism 300 and the heat transfer mechanism 500 are isolated by air to prevent the pipe temperature from rising too quickly and to avoid damage to the heating element due to local overheating. After the heat transfer mechanism 500 heats up, the medium is introduced into the heat exchange mechanism 200. The object to be heated is placed on the surface of the heat exchange mechanism 200 and thus heated. The temperature warning mechanism 400 monitors the temperature of the heating mechanism 300 in real time, and the temperature monitoring mechanism 600 monitors the temperature of the heat transfer mechanism 500 in real time. Adjustments are made as needed according to the corresponding temperatures to ensure that the explosion-proof heater is at a suitable heating temperature.

[0042] Example 2

[0043] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the heating mechanism 300 includes a base plate 301, and multiple electric heaters 302 are vertically mounted in a ring on the surface of the base plate 301.

[0044] Specifically, the heat transfer mechanism 500 includes a pump body 501, which is installed on the bottom inner wall of the heat exchange mechanism 200. Multiple pipes 502 are installed in a ring on the outer wall of the pump body 501. The pipes 502 are located outside the electric heater 302, and one end of the pipes 502 leads to the interior of the heat exchange mechanism 200.

[0045] Furthermore, there are multiple temperature warning mechanisms 400. Each temperature warning mechanism 400 includes a thermal grease sleeve 401 and a copper shell 402. The copper shell 402 is installed on the surface of the base plate 301. The copper shell 402 and the corresponding electric heater 302 are sleeved on the inner wall of the same thermal grease sleeve 401.

[0046] A piston 403 is slidably disposed in the middle of the inner part of the copper shell 402. The cavity formed by the bottom of the piston 403 and the copper shell 402 is filled with hydraulic oil. A fixing rod 404 is installed on the surface of the piston 403. A start / stop button 405 is provided on the top inner wall of the copper shell 402.

[0047] During operation, the temperature warning mechanism 400 monitors the initial maximum temperature of the heating mechanism 300 after heating. If the temperature is too high, exceeding the warning value, the start / stop button 405 is activated via the fixed rod 404 to stop the device. When the entire system starts, the heating mechanism 300 begins to work, heating the hydraulic oil in the internal copper shell 402 cavity. At this time, the hydraulic oil temperature is low and the volume is relatively stable. The piston 403 is in its initial position, and the fixed rod 404 connected to the piston 403 also remains in its initial state. The start / stop button 405 of the heating element is in the open state, heating at maximum power to rapidly raise the hydraulic oil temperature. As heating continues, the temperature of the hydraulic oil gradually increases. Due to the thermal expansion and contraction characteristics of hydraulic oil, it begins to expand, and its volume gradually increases. The hydraulic chamber is a sealed space. The pressure generated by the expansion of the hydraulic oil pushes the piston 403 connected to it to move. According to the thermal expansion coefficient, initial volume, and temperature rise of the hydraulic oil, the expansion of the hydraulic oil will push against the piston 403, causing the piston 403 to drive the fixed rod 404 to move upward. When the critical temperature is reached, the fixed rod 404 touches the start / stop button 405, thereby turning off the power of the device and stopping the heating to avoid overheating and affecting the normal use of the device.

[0048] Example 3

[0049] Reference Figures 1 to 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the heat exchange mechanism 200 includes a heat exchanger 201, which is installed on the surface of the outer casing 101, and one end of the pipe 502 leads to the interior of the heat exchanger 201.

[0050] Specifically, a temperature sensor 202 is installed on the outer wall of the heat exchanger 201, a mounting base 203 is provided on the outer wall of the heat exchanger 201, and a temperature display 204 is installed on the surface of the mounting base 203.

[0051] Furthermore, the temperature monitoring mechanism 600 includes a mounting base 601 and two temperature sensors 602. One end of each temperature sensor 602 is connected to the interior of a corresponding pipe 502. The main body of the temperature sensor 602 is located on the outside of the housing 101. The mounting base 601 is mounted on the outer wall of the housing 101. A temperature display 603 and a temperature display 604 are mounted on the surface of the mounting base 601.

[0052] The mounting base 601 contains a controller, and both ends of the electric heater 302 are equipped with thyristors. The controller controls the power of the electric heater 302 through the thyristors based on the temperatures of the temperature display instrument 603 and the temperature display instrument 604.

[0053] During use, the temperature of the two pipes 502 is monitored by temperature sensor 602, temperature display 603, and temperature display 604. This avoids errors in the detection results and monitors the initial temperature of the medium inside the pipe 502 after it is heated. If the temperature is too high or too low, the controller controls the power of the electric heater 302 through the thyristor, thereby automatically adjusting the temperature through the electric heater 302.

[0054] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
