Abstract
Description
Technical Field
[0001] This utility model relates to a crystallizer detector mounting device, and more particularly to a sleeve device for a crystallizer detector. Background Technology
[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.
[0003] In the metallurgical industry, crystallizers are often used in relatively enclosed and high-temperature conditions, and the detectors for these crystallizers are placed in sleeves and fixed to the crystallizer. Even though there is a large amount of cooling water in the crystallizer, which can isolate some of the heat from inside the crystallizer, the ambient temperature around the crystallizer is still high (up to 80°C or even higher). Through heat transfer, the surface temperature of the detector rises, and when the detector temperature reaches about 65°C, it affects its normal operation, thus affecting the normal operation of the entire continuous casting equipment.
[0004] Existing sleeve designs for fixing detectors are generally simple, serving only a fixing function and unable to provide additional cooling. Therefore, they cannot prevent detector failure caused by high temperatures.
[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0006] The purpose of this invention is to provide a sleeve device for crystallizer detectors, which can cool the detector by setting a gap groove in the sleeve for ventilation, thereby helping to improve the stability of the detector in use.
[0007] To achieve the above objectives, this utility model discloses a sleeve device for a crystallizer detector, used to install the detector and cool it down. The sleeve device for the crystallizer detector includes:
[0008] A sleeve having a cavity for mounting the detector, the sleeve having a first end and a second end disposed opposite to each other, the first end of the sleeve being open and the second end of the sleeve being closed, the sleeve including a gap groove extending in a direction from the first end to the second end, the first end of the sleeve also including an air inlet, the gap groove communicating with the air inlet at the first end of the sleeve, and the gap groove communicating with the cavity at the second end of the sleeve;
[0009] A collar, used to fill the first end of the sleeve after the detector is placed in the cavity, so that the detector is pressed against the cavity.
[0010] The collar has a notch. When low-temperature gas enters the gap groove from the air inlet and absorbs heat through the cavity, it is discharged from the notch toward the first end of the sleeve.
[0011] As a further description of the above technical solution, the first end of the sleeve includes a mounting plate, which is used to install fasteners and cause the collar to be pressed against the opening at the first end of the sleeve by the fasteners.
[0012] As a further description of the above technical solution, the gap groove is provided to cover the sleeve in an annular manner.
[0013] As a further description of the above technical solution, the gap groove is provided near the second end of the sleeve at the point where it connects with the cavity.
[0014] As a further description of the above technical solution, the number of air inlets connected to the gap groove is set to multiple.
[0015] As a further description of the above technical solution, the number of air inlets is set to two, and the two air inlets are arranged symmetrically.
[0016] As a further description of the above technical solution, the collar has multiple notches, and the multiple notches are arranged around the second end of the collar facing the sleeve.
[0017] As a further description of the above technical solution, the sleeve is provided with a screw that penetrates the gap groove, and the screw is used to support the gap groove.
[0018] Based on the above technical solution, the beneficial effects of this utility model are as follows:
[0019] The sleeve device for crystallizer detectors of this invention can provide a ventilation slot in the sleeve. One end of the slot is connected to the air inlet on the open side of the sleeve, and the other end of the slot is connected to the cavity inside the sleeve. This allows the detector installed in the cavity to continuously have its heat carried away by the low-temperature airflow when air is introduced from the air inlet, thus achieving cooling and obtaining a more stable operating environment and avoiding failure.

[0030] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another.

[0031] Please see Figure 1-4 This embodiment provides a sleeve device for a crystallizer detector, used to mount the detector 100 and cool the detector 100. The sleeve device for the crystallizer detector includes:
[0032] Sleeve 1 has a cavity for mounting detector 100. Sleeve 1 has a first end and a second end disposed opposite to each other. The first end of sleeve 1 is configured as an opening and the second end of sleeve 1 is configured as a closed end. Sleeve 1 includes a gap groove 11 extending in the direction from the first end to the second end. The first end of sleeve 1 also includes an air inlet 12. The gap groove 11 communicates with the air inlet 12 at the first end of sleeve 1 and communicates with the cavity at the second end of sleeve 1.
[0033] The collar 2 is used to fill the first end of the sleeve 1 after the detector 100 is placed in the cavity, so that the detector 100 is pressed against the cavity.
[0034] The collar 2 has a notch 21. When low-temperature gas is introduced into the gap groove 11 from the air inlet 12 and absorbs heat through the cavity, it is discharged from the notch 21 toward the first end of the sleeve 1.
[0035] For the above structure, during installation, after fixing the sleeve 1 to the crystallizer, the second end of the detector 100 is inserted into the sleeve 1 with the opening of the first end facing the sleeve 1, until the second end of the detector 100 is inserted into the position of the second end of the sleeve 1 and the first end of the detector 100 is at the position of the first end of the sleeve 1, so that the sleeve 1 covers the detector 100. Then, the collar 2 is inserted into the first end of the sleeve 1, so that the detector 100 is limited in the sleeve 1 by the collar 2 and cannot be removed.
[0036] Based on the above structure, please refer to the following when using it. Figure 4 As the temperature of detector 100 rises, the operator only needs to introduce low-temperature gas (here, low-temperature gas refers to gas with a temperature lower than the current temperature of detector 100; in this embodiment, it can be room temperature gas at 25°C) through the air inlet 12. The gas enters the gap groove 11 from the air inlet 12 and flows towards the second end of sleeve 1 until it flows out from the opening of the gap groove 11 at the second end of sleeve 1. Since the second end of sleeve 1 is set as a closed side, under the pressure, the gas flows towards the first end of sleeve 1. During this process, the gas passes through the gap between the outer surface of detector 100 and the inner wall of sleeve 1, carrying away the heat from detector 100, and reaches the collar 2 at the first end of sleeve 1, from the recess 21 of collar 2. It is worth noting that the collar 2 can be used to install structures with small diameters, such as cables, as long as it does not block the gas discharge from the recess 21 of collar 2. Specifically, the gas flow direction in the above process can be seen from the dashed arrow.
[0037] In the above-described usage, simply inputting gas into the air inlet 12 is sufficient to reduce the temperature of the detector 100, while the sleeve 1 itself still effectively secures the detector 100. Furthermore, the sleeve 1 has a simple structure and low cost. Compared to existing sleeves that only secure the detector 100, the sleeve device for the crystallizer detector in this embodiment does not occupy significantly more space structurally, yet achieves a cooling effect on the detector 100.
[0038] Furthermore, the first end of the sleeve 1 includes a mounting plate 13, which is used to mount fasteners and cause the collar 2 to be pressed against the opening at the first end of the sleeve 1 by the fasteners. See details below. Figure 1 and Figure 3 The mounting plate 13 is a plate-shaped metal block protruding along the extension direction of the sleeve 1. It is provided with holes for fastener installation, which can be internal threaded holes. When the fastener passes through the hole, it can be blocked radially outside the collar 2 to limit the collar 2 and prevent the collar 2 from coming off the sleeve 1, thereby preventing the detector 100 from coming off the sleeve 1.
[0039] Furthermore, the gap groove 11 is provided along the annular covering sleeve 1. Simultaneously, the gap groove 11 is located near the second end of the sleeve 1 where it connects to the cavity. Specifically, in this embodiment, the main body of the sleeve 1 can be considered as a multi-layered plate cylindrical structure with a gap layer. The gap groove 11 can cover the entire surface of the sleeve 1. From a manufacturing perspective, it is essentially a combination of two overlapping sleeves, which is relatively easy to manufacture. From an airflow perspective, the structure of this embodiment can obtain an airflow channel with the largest cross-sectional area, which is relatively uniform and has a better heat dissipation effect.
[0040] Furthermore, the number of air inlets 12 connected to the gap groove 11 is set to multiple. Further, the number of air inlets 12 is set to two, with the two air inlets 12 symmetrically arranged. Through the above structural arrangement, airflow is simultaneously introduced into the gap groove 11 from both the upper and lower air inlets 12, making the internal airflow more balanced and avoiding a situation where only one side of the detector 100 effectively dissipates heat.
[0041] Furthermore, the collar 2 has multiple notches 21, which are arranged around the second end of the collar 2 facing the sleeve 1. That is to say, in this embodiment, one end of the collar 2 is set with a petal-shaped multi-opening layout, which can make the gas discharged from the sleeve 1 faster and more uniform.
[0042] Further, please see Figure 4 In this embodiment, the sleeve 1 has a screw 14 penetrating the gap 11 within the gap 11. The screw 14 provides support for the narrow space formed by the gap 11, preventing deformation. Specifically, there are multiple screws 14, which are arranged at equal angular intervals around the extension direction of the sleeve 1. For example, in... Figure 5 In this embodiment, four screws are used. The presence of screws 14 ensures that the gaps in the slots 11 are uniform, which helps to better cool the detector 100.
