Description

Technical Field

[0001] This utility model belongs to the field of sagger sampling technology, and in particular relates to a sintering material sampling device that uses a sagger as a sintering carrier. Background Technology

[0002] Sintered materials refer to bulk materials with specific strength, porosity and microstructure formed by heating powdered or granular raw materials at a temperature below their melting point through high-temperature solid-state reaction or physical metallurgical process, causing the particles to bond and densify. The key process is the diffusion, fusion and recrystallization between particles, rather than complete melting (unlike smelting). Essentially, it achieves mechanical bonding or chemical bonding between particles through thermal activation, forming porous or dense solids.

[0003] During the sintering process, due to different furnace conditions, the materials discharged from each furnace are somewhat different. In the sintering process, the discharge compaction is a key technical indicator that is controlled. It not only has considerable guiding significance for the adjustment of parameters in the subsequent crushing process, but also plays a certain role in monitoring the process of the kiln equipment. However, due to errors in sampling personnel or sampling methods, the sampling points of the discharged materials differ greatly, which greatly reduces the reliability of the test. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a sintering material sampling device using a sintering crucible as the sintering carrier, which can more accurately solve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a sintering material sampling device using a sintering crucible as a sintering carrier, including a cover plate. The lower surface of the cover plate is provided with a fastening component. The cover plate is provided with three circular through slots, and a sampling component is placed in each of the circular through slots. The sampling component includes an outer cylinder, which cooperates with the circular through slots. An inner cylinder is sleeved inside the outer cylinder. Both the outer cylinder and the inner cylinder are provided with the same sampling hole.

[0007] Preferably, the fastening assembly includes four sliders, the inner side of the cover plate is provided with four square grooves, the four sliders are located in the square grooves, the sliders are slidably connected to the cover plate, the lower surface of each slider is fixedly connected to an extrusion block, the side wall of the square groove is fixedly connected to a support rod, the support rod passes through the slider and is slidably connected to the slider, and a first spring is fixedly connected between the slider and the square groove.

[0008] Preferably, all of the extrusion blocks have a bevel on one side.

[0009] Preferably, two mounting plates are fixedly connected to the upper surface of the cover plate, and a handle is fixedly connected to the upper surface of the mounting plates.

[0010] Preferably, the upper surface of the cover plate is fixedly connected to the three circular through slots with fixing rings, and each fixing ring is provided with two slots. The outer cylinder sidewall is fixedly connected to two blocks, which cooperate with the slots.

[0011] Preferably, a support plate is fixedly connected to the outer side of the inner cylinder, a sliding rod is slidably connected to the support plate, the sliding rod passes through the support plate, a limiting block is fixedly connected to the upper end of the sliding rod, a second spring is fixedly connected between the limiting block and the support plate, and slots are provided on the upper surfaces of the two locking blocks, the slots cooperating with the sliding rods.

[0012] Preferably, one side of one of the support plates on all the outer cylinders is provided with a marking groove, and the marking groove is opposite to the sampling hole on the side wall of the outer cylinder.

[0013] The sintering material sampling device using a sintering crucible as a sintering carrier proposed in this utility model can bring the following beneficial effects:

[0014] 1. By setting a cover plate, which is fixed to the sagger by fastening components, the position of the cover plate and the sagger is relatively fixed. The cover plate has three circular through slots, which can take three points of sintered material. The sampling position is fixed each time, which greatly improves the reliability of material compaction after exiting the furnace and can reduce abnormal test results caused by different sampling points.

[0015] 2. By setting the inner and outer cylinders, when the sampling component is placed, the sampling holes of the inner and outer cylinders are misaligned. The sliding rod on the inner cylinder is inserted into the slot on a card block to keep the sampling holes of the inner and outer cylinders misaligned. This prevents the inner cylinder from rotating due to shaking when the outer cylinder is inserted into the material, thus aligning the sampling holes and allowing the material to enter.

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, an embodiment of this utility model proposes a sintering material sampling device using a sintering crucible as a sintering carrier. It includes a cover plate 1, a fastening assembly 2 on the lower surface of the cover plate 1, and three circular through slots on the cover plate 1. Sampling components 3 are placed in each of the circular through slots. Each sampling component 3 includes an outer cylinder 31 that mates with the circular through slots. An inner cylinder 32 is fitted inside the outer cylinder 31. Both the outer cylinder 31 and the inner cylinder 32 have identical sampling holes. The sampling components 3 and the cover plate 1 are made of high-temperature resistant and wear-resistant ceramic material. In use, the cover plate 1 is placed above the sintering crucible, and the fastening assembly 2 secures the cover plate 1 to the sintering crucible. The sampling components 3 are then inserted into the three circular through slots on the cover plate 1. When the sampling component 3 is inserted into the through slot, the sampling holes on the outer cylinder 31 and the inner cylinder 32 are misaligned, making sampling impossible. After the sampling component 3 is inserted, the inner cylinder 32 is rotated to align the sampling holes on the inner cylinder 32 with those on the outer cylinder 31. The material enters the inner cylinder 32 through the sampling holes on the inner cylinder 32 and the outer cylinder 31, completing the sampling. By setting a circular through slot on the cover plate 1 to place the sampling component 3 and fixing the sampling point, the sampling position is fixed each time, which greatly improves the reliability of the material's extrusion compaction. Moreover, three points of sintered material can be sampled at one time. Before the sampling component 3 is placed, the sampling holes on the inner cylinder 32 and the outer cylinder 31 are misaligned to prevent the material from entering the inner cylinder 32 in advance.

[0025] like Figure 2 and Figure 3 As shown, the fastening assembly 2 includes four sliders 21. The inner side of the cover plate 1 is provided with four square grooves, and the four sliders 21 are located in the square grooves. The sliders 21 are slidably connected to the cover plate 1. The lower surface of each slider 21 is fixedly connected to a pressing block 22. The side wall of the square groove is fixedly connected to a support rod 23. The support rod 23 passes through the slider 21 and is slidably connected to the slider 21. A first spring 24 is fixedly connected between the slider 21 and the square groove. One side of each pressing block 22 is provided with an inclined surface. When in use, the inclined surface of the pressing block 22 is first pressed against the inner side of the sagger, and the cover plate 1 is pressed down. Under the action of the inclined surface, the pressing block 22 slides inward. As it descends, when the vertical side of the pressing block 22 contacts the inner wall of the sagger, the pressing block 22 is pushed by the first spring 24 to press against the four corners of the inner side of the sagger. The cover plate 1 is fixed on the sagger, which facilitates the fixing of the sampling point.

[0026] like Figure 1 As shown, two mounting plates 4 are fixedly connected to the upper surface of the cover plate 1, and a handle 5 is fixedly connected to the upper surface of the mounting plate 4. After sampling is completed, the handle 5 can be lifted directly to pull the cover plate 1 out of the sagger, which is convenient to use.

[0027] like Figure 1 and Figure 3 As shown, the upper surface of the cover plate 1 is fixedly connected to the three circular through slots with fixing rings 6. Each fixing ring 6 is provided with two slots. The side wall of the outer cylinder 31 is fixedly connected to two blocks 7. The blocks 7 cooperate with the slots. When the sampling component 3 is placed, the blocks 7 on the outer cylinder 31 are aligned with the slots, and the inner cylinder 32 is pressed down so that the blocks 7 are inserted into the slots, so that the outer cylinder 31 in the three circular through slots is inserted into the material at the same depth.

[0028] like Figure 3 and Figure 4 As shown, a support plate 8 is fixedly connected to the outer side of the inner cylinder 32, and a sliding rod 9 is slidably connected to the support plate 8. The sliding rod 9 passes through the support plate 8, and a limiting block is fixedly connected to the upper end of the sliding rod 9. A second spring 10 is fixedly connected between the limiting block and the support plate 8. The upper surfaces of the two locking blocks 7 are provided with slots, which cooperate with the sliding rod 9. When the sampling component 3 is placed, the sampling holes of the inner cylinder 32 and the outer cylinder 31 are misaligned. The sliding rod 9 on the inner cylinder 32 is inserted into the slot on one of the locking blocks 7 to keep the sampling holes of the inner cylinder 32 and the outer cylinder 31 misaligned. This prevents the inner cylinder 32 from rotating when the outer cylinder 31 is inserted into the material, so that the sampling holes are aligned and the material enters.

[0029] like Figure 3 and Figure 4 As shown, one side of each support plate 8 on all outer cylinders 31 is provided with a marking groove. The marking groove is opposite to the sampling hole on the side wall of the outer cylinder 31. When the sliding rod 9 on the inner cylinder 32 is inserted into the slot on the support plate 8 with the marking groove, it means that the sampling holes of the inner cylinder 32 and the outer cylinder 31 are opposite and sampling can be performed. Since the sampling hole is located inside the material after the outer cylinder 31 is inserted, it cannot be viewed. By setting the marking groove, it is convenient to control the sampling holes of the inner cylinder 32 and the outer cylinder 31.

[0030] Working principle: In use, first, the inclined surface of the extrusion block 22 is pressed against the inner side of the sagger, and the cover plate 1 is pressed down. Under the action of the inclined surface, the extrusion block 22 slides inward. As it descends, when the vertical side of the extrusion block 22 contacts the inner wall of the sagger, the first spring 24 pushes the extrusion block 22 against the inner side of the sagger, and the cover plate 1 is fixed on the sagger. The sliding rod 9 on the inner cylinder 32 is inserted into the slot on a locking block 7. The outer cylinder 31 is inserted into the three circular through slots on the cover plate 1 and extended into the material until the locking block 7 on the outer cylinder 31 enters the slot. Then, the sliding rod 9 is pulled away from the slot, and the inner cylinder 32 is rotated so that the sliding rod 9 is aligned with the locking block 7 with the marking slot. At this time, the sampling holes on the inner cylinder 32 and the outer cylinder 31 are aligned, and the material enters the inner cylinder 32 to start sampling.
