Description

Technical Field

[0001] This utility model relates to the technical field of eddy current sensor protective sleeves, specifically a high-temperature resistant protective sleeve for eddy current sensors. Background Technology

[0002] The metallurgical industry is one of the core application areas of eddy current sensors. The connection between the two mainly stems from the strong demand for "non-contact measurement in high temperature and harsh environment" in the entire metallurgical production process. This perfectly matches the monitoring needs of key parameters such as metal liquid level, size, defects, and equipment status in the metallurgical process, and runs through multiple core links from raw material smelting to finished product processing.

[0003] An existing patent (publication number: CN217877526U) discloses an eddy current sensor. This eddy current sensor allows for convenient rotational adjustment between the inner and outer shells, facilitating the adjustment of the sensing probe angle and improving the sensing effect. The sensor uses locking bolts to fix the inner and outer shells, and spring washers to prevent the flange nuts from loosening, ensuring stable operation even in environments with significant equipment vibration, thus guaranteeing the stability of the eddy current sensor. Furthermore, the sensor uses a positioning groove to fix the outer shell, preventing changes in the sensing probe angle due to changes in the outer shell angle after adjustment, ensuring the sensing accuracy of the probe. This invention features a compact and rationally designed structure, effectively ensuring the stable operation of the eddy current sensor under vibration conditions, effectively guaranteeing the sensing accuracy of the probe, facilitating the adjustment of the probe angle, and ensuring the angle remains fixed after adjustment, thereby improving the overall performance of the eddy current sensor.

[0004] To address the aforementioned issues, while existing patents have proposed solutions that can improve the performance of eddy current sensors through the coordination of components such as the housing, in practice, the eddy current sensors are used in high-temperature environments due to their placement on metal casting equipment. Furthermore, in continuous casting production lines, molten metal splashes may damage the eddy current sensors. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] 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.

[0021] 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 embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figure 1 - Figure 4 This is the first embodiment of the present utility model. This embodiment provides a high-temperature resistant protective sleeve for an eddy current sensor, including: an equipment duct 1, a connecting cover 2, a limiting shell 3, a through hole 4, and a connecting ring 5; the connecting cover 2 is sleeved on the outside of the equipment duct 1, the limiting shell 3 is fixedly installed on the top of the connecting cover 2, the through hole 4 is opened on the inner wall of the limiting shell 3, and the connecting ring 5 is fixedly installed inside the connecting cover 2, and also includes: The protective mechanism 6 and the sealing mechanism 7 are provided; the protective mechanism 6 is located below the connecting cover 2, and the sealing mechanism 7 is located inside the limiting shell 3.

[0023] Specifically, the protective mechanism 6 includes: a bakelite shell 601, an insulating layer 602, an aerogel filling layer 603, a heat dissipation layer 604, a wear-resistant layer 605, a sliding plate 606, a fixing block 607, a slot 608, a locking block 609, and a mounting plate 610; the bakelite shell 601 is sleeved on the outside of the connecting ring 5, the insulating layer 602 is embedded on the side of the bakelite shell 601 facing the connecting ring 5, and the aerogel filling layer 603 is embedded on the inner wall of the bakelite shell 601.

[0024] Furthermore, the insulating layer 602 is a polyimide film, which provides high temperature resistance and insulation, and together with the aerogel filler layer 603, it can effectively reduce the operating temperature of the sensor inside the protective sleeve.

[0025] Specifically, a heat dissipation layer 604 is fixedly installed on the outer wall of the bakelite shell 601, and a wear-resistant layer 605 is fixedly installed on the outer wall of the heat dissipation layer 604.

[0026] Furthermore, the heat dissipation layer 604 is a high emissivity ceramic coating, which enhances heat dissipation through radiation, and the wear-resistant layer 605 is a silicon carbide coating, which provides wear resistance while reducing the temperature of the sensor's operating environment.

[0027] Specifically, a sliding plate 606 is slidably connected inside the connecting cover 2, and a fixing block 607 is fixedly installed at the front end of the sliding plate 606.

[0028] Furthermore, the sliding plate 606 is easily adjustable as a set by being threaded to the connecting cover 2, and the fixing block 607 allows the operator to easily hold and adjust it.

[0029] Specifically, the fixed block 607 has a slot 608 inside, and a locking block 609 is rotatably connected inside the slot 608. An mounting plate 610 is fixedly installed on one side of the locking block 609.

[0030] Furthermore, the mounting plate 610 is fixed to the sensor with bolts, which can keep the mounting plate 610 and the sensor stable when the fixing block 607 is adjusted, and avoid the cable from getting tangled due to rotation.

[0031] Specifically, the connecting cover 2 is threadedly connected to the bakelite shell 601 via the connecting ring 5, and the bakelite shell 601 and the connecting cover 2 form a detachable structure.

[0032] Furthermore, the connecting cover 2 and the connecting ring 5 facilitate the connection and disassembly of the bakelite shell 601 via threaded connection, so as to facilitate the disassembly and assembly of the protective cover and the maintenance or adjustment of the internal sensor. The connecting cover 2 is also made of bakelite shell 601, with an aerogel filling layer 603 inside, and coated with a heat dissipation layer 604 and a wear-resistant layer 605.

[0033] In use, the sensor is first fixed with the mounting plate 610 and bolts. Then, the position of the sliding plate 606 is adjusted by holding the fixing block 607 and sliding along the connecting ring 5. This allows the sensor to be inserted into the bakelite shell 601 for storage and protection. With the help of the slot 608 and the locking block 609, the mounting plate 610 is kept from rotating when adjusting the sliding plate 606 to avoid tangling of the connecting cable and pipe. The sensor can be stably connected to the equipment duct 1 after passing through the through hole 4. It can be easily and quickly assembled with the bakelite shell 601 through the connecting cover 2 and the connecting ring 5, which makes it easy to disassemble and maintain the protective cover. With the help of the insulating layer 602, the aerogel filling layer 603, the heat dissipation layer 604 and the wear-resistant layer 605, it can not only provide insulation, wear resistance and protection, but also avoid excessive heat transfer, reduce the working environment of the sensor and avoid the impact of long-term use.

[0034] In summary, the connecting ring 5 facilitates the assembly of the connecting cover 2 and the bakelite shell 601, enabling the sensor to be disassembled and maintained. It also works with the mounting plate 610 and bolts to secure the sensor, and with the slot 608 and locking block 609 to prevent the cable from rotating and becoming tangled, thus ensuring a stable connection with the equipment duct 1. Furthermore, the bakelite shell 601, insulation layer 602, aerogel filling layer 603, heat dissipation layer 604, and wear-resistant layer 605 provide both protection and insulation for the sensor, preventing external temperatures from excessively affecting the sensor's operating environment and thus its performance.

[0035] Example 2: Please see Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0036] Specifically, the sealing mechanism 7 includes: a connection hole 701, a vent pipe 702, an air supply bladder 703, a sealing bladder 704, a thickening layer 705, and a mounting hole 706; the connection hole 701 is opened on one side of the through hole 4 at the top of the connecting cover 2, and the vent pipe 702 extends out of the inside of the connection hole 701.

[0037] Furthermore, by opening the through hole 4, a through space is reserved, allowing the vent pipe 702 to penetrate into the interior of the limiting shell 3.

[0038] Specifically, the connecting ring 5 has an air supply bladder 703 embedded inside, and the limiting shell 3 has a sealing bladder 704 embedded inside.

[0039] Furthermore, the air supply bladder 703 and the sealing bladder 704 are connected by a vent pipe 702. When the sliding plate 606 drives the sensor to adjust, the air supply bladder 703 can be pressed to allow gas to enter the sealing bladder 704, thereby sealing the equipment air duct 1 within the limiting shell 3 and preventing the entry of dust and oil.

[0040] Specifically, the top and bottom of the sealing airbag 704 are fitted with thickened layers 705, and the sealing airbag 704 and the air supply airbag 703 are provided with mounting holes 706.

[0041] Furthermore, the thickened 705 layer is made of the same material as the airbag, both of which are made of high-temperature resistant nylon fabric and incorporate glass fiber to improve overall practicality.

[0042] Specifically, the sealing airbag 704 is tightly fitted to the limiting shell 3, and the sealing airbag 704 is stitched together with the thickened layer 705.

[0043] Furthermore, after the gas enters the sealing airbag 704, it fills and adheres to the inside of the limiting shell 3, thereby pressing and adhering to the equipment air duct 1 and the pipeline cables connected to the sensor, achieving a sealing effect.

[0044] In use, when the sliding plate 606 is adjusted and slid along the connecting cover 2, the air supply bag 703 is squeezed, and the gas is delivered to the sealing bag 704 through the ventilation pipe 702, thereby filling the inside of the limiting shell 3 and fitting the connection between the equipment air duct 1 and the sensor, so as to achieve a sealing effect. In addition, the thickened layer 705 improves the wear resistance of the sealing bag 704.

[0045] In summary, the gas is pushed from the air supply bladder 703 to the sealing bladder 704 by the sliding plate 606, thereby achieving a sealing effect inside the limiting shell 3, preventing dust, dirt and oil from the surrounding working environment from entering, and improving the sealing effect of the entire protective cover.
