Description

Technical Field

[0001] This utility model relates to the technical field of refractory material testing equipment, and in particular to a refractoriness tester for refractory materials. Background Technology

[0002] In the field of refractory material refractoriness testing, traditional refractoriness testing machines have significant technical bottlenecks. The observation window of existing equipment is usually fixed on one side or top of the test chamber, resulting in a single observation angle and blind spots in monitoring.

[0003] When the sample is misaligned during heating or when molten material or dust adheres to the glass surface, operators may find it difficult to adjust their viewing angle to obtain a clear observation image. This limited field of view may lead to errors in the determination of refractoriness, affecting the accuracy and reliability of the test. In addition, the test chambers of traditional testing machines are mostly of a single unit structure. If maintenance or replacement of internal components (such as the sample holder and heating element) is required, the entire equipment must be disassembled, which is a cumbersome and time-consuming process, reducing the efficiency of equipment use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a refractoriness testing machine for refractory materials, which solves the problem that the observation window of existing equipment is usually fixed on one side or top of the test chamber, resulting in a single observation angle and blind spots in monitoring.

[0006] (II) Technical Solution

[0008] Preferably, the connecting mechanism includes an upper fixed frame and a lower fixed frame fixedly mounted on a two-section test chamber, and the lower fixed frame is provided with a connecting groove corresponding to the upper fixed frame.

[0009] Preferably, the rotating mechanism includes a gear fixedly mounted on the output shaft of the drive motor, and a gear ring that meshes with the gear is fixedly mounted on the mounting ring.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are:

[0015] 1. The rotation mechanism, consisting of a drive motor, gears, and a gear ring, enables the rotation of the observation port and observation glass on the mounting ring, breaking through the limitations of the traditional fixed observation window and ensuring comprehensive and blind-spot-free monitoring of the sample.

[0016] 2.

Detailed Implementation

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] Reference Figure 1-3 A refractoriness testing machine for refractory materials includes a test chamber 1. The test chamber 1 is also equipped with components such as a sample rack. The above components are basic components. Since this solution does not improve the above components, it is only a simple illustration. For specific components, please refer to the existing technology.

[0024] The test chamber 1 is designed in two sections, which are connected by a connecting mechanism. An installation ring 2 is provided between the two sections of the test chamber 1. The vertical cross-section of the installation ring 2 is H-shaped. The installation ring 2 and the two sections of the test chamber 1 are sealed sliding connections. The sealed sliding connection is existing technology. For details on how to achieve the sealed sliding connection, please refer to the existing technology disclosure. This solution will not elaborate on the details.

[0025] The mounting ring 2 is provided with an observation port 3, and an observation glass 4 is provided inside the observation port 3. The observation glass 4 is made of high-temperature resistant glass, and the internal conditions can be observed through the observation glass 4. A support frame 8 is fixedly provided on the upper test chamber 1, and a drive motor 9 is fixedly provided on the support frame 8. The drive motor 9 is connected to the mounting ring 2 through a rotation mechanism.

[0026] The connecting mechanism includes an upper fixed frame 5 and a lower fixed frame 6 fixedly mounted on the two-section test chamber 1. The lower fixed frame 6 has a connecting groove 12 corresponding to the upper fixed frame 5. The upper fixed frame 5 has a pressing groove 13, and a positioning block 14 is provided in the pressing groove 13 via a spring 15. The lower fixed frame 6 has a positioning hole 7, which corresponds to the positioning block 14 and communicates with the connecting groove 12. When the two-section test chamber 1 and the mounting ring 2 are connected together, the vertical part of the upper fixed frame 5 is located in the connecting groove 12 on the lower fixed frame 6. The positioning block 14 enters the positioning hole 7 under the compression of the spring 15, thereby achieving a stable connection of multiple components. The positioning block 14 can be pressed to compress the spring 15 and disengage from the positioning hole 7, thereby releasing the connection between the upper fixed frame 5 and the lower fixed frame 6, and facilitating the disassembly and separation of the two-section test chamber 1.

[0027] The rotating mechanism includes a gear 10 fixedly mounted on the output shaft of the drive motor 9, and a gear ring 11 fixedly mounted on the mounting ring 2 that meshes with the gear 10. Since the gear ring 11 is fixedly mounted and the two-section test chamber 1 does not rotate, the mounting ring 2 can rotate relative to the two-section test chamber 1 when the drive motor 9 is started, thereby realizing the rotational adjustment of the observation port 3 and the observation glass 4.

[0028] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0029] In practical use, the working principle of this utility model is as follows:

[0030] The refractory material sample is placed on the sample holder (existing technology component) inside the test chamber 1, and the test program is started. When it is necessary to observe the morphological changes of the sample during the heating process, the drive motor 9 (located on the support frame 8) is started, and the gear 10 on its output shaft meshes with the gear ring 11 on the mounting ring 2. Since the gear ring 11 is fixed and the two-section test chamber 1 is stably connected by a connecting mechanism (the positioning block 14 of the upper fixed frame 5 is engaged with the positioning hole 7 of the lower fixed frame 6), the mounting ring 2 can rotate relative to the test chamber 1. The observation port 3 and the observation glass 4 on the mounting ring 2 rotate accordingly. The operator can adjust the observation port 3 to a suitable angle as needed and observe the softening, melting, and other states of the sample inside the test chamber 1 through the high-temperature resistant observation glass 4 to obtain refractory test data. If it is necessary to disassemble the test chamber 1 for maintenance or replacement of parts, press the positioning block 14 to compress the spring 15 in the extrusion groove 13, disengaging it from the positioning hole 7, thereby releasing the connection between the upper fixed frame 5 and the lower fixed frame 6 and separating the two-section test chamber 1.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
