Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment technology, specifically to a shock-resistant pressure gauge and an electric heat tracing device to prevent freezing in winter. Background Technology

[0002] In dry quenching coke production systems, on-site pressure gauges are key equipment for measuring process parameters. Among them, boiler drum pressure gauges are particularly important, as they are used to accurately measure boiler drum pressure, which is one of the core parameters for ensuring the stable and safe operation of the dry quenching coke system.

[0003] However, most existing boiler drum pressure gauges are shock-resistant gauges, with shock-resistant fluid injected into the gauge head to enhance their shock resistance. These gauges are largely installed outdoors, exposed to the natural environment for extended periods, and significantly affected by temperature fluctuations. Especially in winter, when temperatures drop drastically, the shock-resistant fluid is prone to freezing. Once the fluid freezes, the gauge pointer will malfunction, the spring will deform irregularly, and ultimately, the gauge will be damaged. Due to the unique operating conditions of boiler drums, which measure high-temperature, high-pressure saturated steam (approximately 10 MPa) and temperatures reaching 800°C, maintenance personnel face extremely high safety risks when replacing damaged pressure gauges under these conditions. Therefore, the reliability and safety of existing pressure gauges in winter urgently need improvement, and a device that can effectively prevent pressure gauges from freezing in winter is urgently required. Utility Model Content

By installing a heating cable with a vortex-shaped section within the device's base, uniform and efficient heat is provided to the anti-vibration fluid at the gauge head, effectively preventing the fluid from freezing in winter. This avoids problems such as pointer malfunction and irregular spring deformation caused by frozen anti-vibration fluid, thereby significantly extending the pressure gauge's service life, reducing the frequency of pressure gauge replacement, lowering equipment maintenance costs, and improving device safety.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a shock-resistant pressure gauge anti-freezing electric heat tracing device, comprising a device base, electric heating cables, and a fixing unit;

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This application provides a shock-resistant pressure gauge anti-freezing electric heat tracing device, which solves the problem that most existing boiler drum pressure gauges are shock-resistant, with anti-vibration fluid injected into the gauge head to enhance their shock resistance. However, these pressure gauges are mostly installed outdoors and exposed to the natural environment for a long time, making them significantly affected by temperature changes. In winter, when the temperature drops sharply, the anti-vibration fluid is prone to freezing.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Example 1: This utility model embodiment discloses a shock-resistant pressure gauge anti-freezing electric heat tracing device, according to the attached... Figure 1-5 As shown, it includes a device base 1, electric heating cables 2, and a fixing unit 3;

[0031] The device base 1 is movably attached to the outside of the pressure gauge body 5, which is mounted on the pipeline system; the device base 1 provides the installation foundation for the entire electric heat tracing device.

[0032] The heating cable 2 is installed inside the device base 1, and the heating cable 2 has a vortex 21. When the heating cable 2 is energized, it can generate heat to provide heat tracing for the anti-vibration fluid at the pressure gauge head, preventing it from freezing in winter. The design of the vortex 21 increases the contact area between the heating cable 2 and the anti-vibration fluid, allowing heat to be transferred to the anti-vibration fluid more evenly and quickly, thus improving the heat tracing efficiency.

[0033] The fixing unit 3 is mounted on the device base 1 and is used to secure the pressure gauge body 5. The fixing unit 3 includes:

[0034] The support plate 31 is mounted on the device base 1;

[0035] Clamping arms 32 are slidably connected inside the device base 1, and the pressure gauge body 5 is clamped between the two sets of clamping arms 32.

[0036] The lead screw 33 is threadedly connected to the bearing plate 31 and rotatably connected to the clamping arm 32.

[0037] By rotating the lead screw 33, the clamping arm 32 can slide within the device base 1, thereby clamping and releasing the pressure gauge body 5. The lead screw 33 is equipped with a rotating handle 331, making it convenient for operators to rotate the lead screw 33 and improving operational ease. The sliding of the clamping arm 32 facilitates the clamping and positioning of the pressure gauge body 5, while also providing good versatility.

[0038] A rubber pad 323 is fixedly connected to the clamping arm 32. The rubber pad 323 can increase the friction between the clamping arm 32 and the pressure gauge body 5, and at the same time play a buffering role to avoid damage to the pressure gauge body 5 during the clamping process.

[0039] A lateral support rod 321 is fixedly connected to the clamping arm 32, and a lateral support tube 322 is fixedly connected to the bearing plate 31. The lateral support rod 321 is slidably connected inside the lateral support tube 322. The design of the lateral support rod 321 and the lateral support tube 322 ensures the stability of the clamping arm 32 during the sliding process, making the clamping more reliable.

[0040] A panel 4 is movably attached to the front of the device base 1, and an acrylic plate 42 is provided on the panel 4. The panel 4 serves to protect the internal heating cables 2 and the pressure gauge body 5, while not affecting the operator's observation of the value displayed on the dial of the pressure gauge body 5.

[0041] Acrylic sheet 42 has advantages such as high transparency and good weather resistance, and can clearly display the pressure gauge reading.

[0042] An arc-shaped locking block 41 is fixedly connected to the panel 4. The arc-shaped locking block 41 is clamped between the pressure gauge body 5 and the clamping arm 32. This fixing method makes it easy to assemble and disassemble the panel 4.

[0043] The operation steps of this shock-resistant pressure gauge anti-freezing electric heating device are as follows: First, the device base 1 is movably attached to the outside of the pressure gauge body 5; then, by rotating the rotating handle 331 on the lead screw 33, the lead screw 33 drives the clamping arm 32 to slide, clamping the pressure gauge body 5 between the two sets of clamping arms 32 to ensure a firm fixation; next, the panel 4 is movably attached to the front of the device base 1, so that the arc-shaped locking block 41 is clamped between the pressure gauge body 5 and the clamping arm 32; finally, in low-temperature conditions, the electric heating cable 2 is energized, and the heat generated by the electric heating cable 2 is transferred to the anti-vibration fluid at the pressure gauge head through the vortex part 21 to achieve the heating function and prevent the anti-vibration fluid from freezing.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
