[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-3 The utility model provides a high-temperature crucible placement device after carbon and sulfur detection, comprising:

[0024] The placing rack is provided with several groups in the vertical direction, and the adjacent placing racks are detachably connected by fixing components. There are four groups of fixing components, and the four groups of fixing components are respectively arranged at the four corners of the placing rack. The fixing components include a fixing rod 1 and a threaded rod 2 arranged vertically. A slide groove 3 is provided at the bottom of the fixing rod 1, and the threaded rod 2 is inserted into the slide groove 3. An adjusting nut 4 is rotatably connected to the bottom of the fixing rod 1, and the adjusting nut 4 is threadedly matched with the threaded rod 2;

[0025] Positioning mechanism, the positioning mechanism is provided with several groups, the placement frame is provided with several placement stations in an array with equal spacing, the placement stations, the placement stations are provided with crucibles, several groups of positioning mechanisms are respectively provided on several placement stations, and the positioning mechanisms are limitedly matched with the crucibles;

[0026] Among them, the fixed rod 1 is fixedly connected to the bottom of the placement rack, the threaded rod 2 is fixedly connected to the top of the placement rack, and the fixed rod 1 and threaded rod 2 on adjacent placement racks are correspondingly arranged.

[0027] When the utility model is used, the crucible is placed on the placing station of the placing rack and is positioned by the positioning mechanism on the placing station. When the placing rack is full, the crucible is placed on the stacked placing rack. The fixing rod 1 and the threaded rod 2 cooperate to install two adjacent placing racks. The distance between the two adjacent placing racks is adjusted by setting the adjusting nut 4. The space occupancy rate of the device is reduced while the heat dissipation effect of the device is ensured. The bottom of the placing rack at the bottom is installed with a bottom plate to ensure the stability of the device.

[0028] The utility model uses a placement rack to place the crucible when it is cooled, and a positioning mechanism is provided to prevent the crucible from falling. Multiple placement racks are stacked in layers to ensure the heat dissipation effect of the device while reducing the space occupancy rate of the device.

[0029] According to a further optimized solution, the placement frame includes a frame 5 and a perforated plate 6 fixedly connected to the frame 5, and a plurality of placement stations are arranged in an evenly spaced array on the perforated plate 6, and the fixed rod 1 and the threaded rod 2 are both fixedly connected to the frame 5. The arrangement of the perforated plate 6 can improve the heat dissipation effect of the device and reduce the weight of the device.

[0030] Further optimization scheme, a positioning groove 7 is provided at the bottom of the chute 3, the cross-sectional shape of the positioning groove 7 is rectangular, and a positioning rod 8 is fixedly connected to the end of the threaded rod 2, the positioning rod 8 is adapted to the positioning groove 7, and the length of the diagonal of the positioning groove 7 is less than the diameter of the threaded rod 2, and the diameter of the threaded rod 2 is less than the diameter of the chute 3. The setting of the positioning groove 7 and the positioning rod 8 can quickly position the placement rack when the placement racks are stacked. When in use, the four positioning rods 8 first cooperate with the positioning grooves 7 on the four fixed rods 1 of the upper placement rack, and then the adjusting nut 4 is rotated to adjust the distance between the two placement racks, thereby reducing the space occupancy rate while ensuring the ventilation effect. The length of the positioning rod 8 is greater than the length of the chute 3, and less than the sum of the length of the chute 3 and the length of the positioning groove 7.

[0031] According to a further optimized solution, the positioning mechanism includes a support ring 18 and a positioning assembly symmetrically arranged on the support ring 18. The support ring 18 is fixedly connected to the placement station, the support ring 18 is sleeved on the outer wall of the crucible, and the positioning assembly and the crucible are limitedly matched.

[0032] To further optimize the solution, the positioning assembly includes a support plate 9 fixedly connected to the side wall of the support ring 18, a pad 10 is slidably connected to the support plate 9, a slide rod 11 is vertically fixedly connected to the bottom of the pad 10, a slide hole is opened on the top surface of the support ring 18, the bottom of the slide rod 11 is slidably connected to the slide hole, a support spring 12 is fixedly connected between the pad 10 and the top surface of the support ring 18, and the support spring 12 is sleeved on the slide rod 11; a first clamping block 13 is fixedly connected to the top surface of the pad 10, a connecting rod 14 is horizontally slidably connected to the top of the support plate 9, a positioning block 15 is fixedly connected to one end of the connecting rod 14, a second clamping block 16 is fixedly connected to the bottom of the positioning block 15, a side of the first clamping block 13 away from the top edge of the crucible is limitedly matched with the second clamping block 16, the positioning block 15 is limitedly matched with the top of the crucible, a compression spring 17 is fixedly connected between the positioning block 15 and the support plate 9, and the compression spring 17 is sleeved on the connecting rod 14.

[0033] In this embodiment, the top edge of the crucible contacts with the pad 10, exerting a downward pressure on the pad 10, thereby causing the first clamping block 13 to move downward, and the first clamping block 13 moves downward and separates from the second clamping block 16, and the compression spring 17 exerts an elastic force on the positioning block 15, thereby causing the positioning block 15 to pop out and form a limiting effect between the top of the crucible. It should be noted that in this embodiment, the first clamping block 13 and the second clamping block 16 are staggered, and the staggered distance between the two is smaller than the distance between the pad 10 and the top surface of the support ring 18, thereby ensuring that the two can be separated. At the same time, in some cases, the crucible adopts a cylindrical shape, and the bottom diameter is smaller than the top diameter, and the top edge portion does not extend. At this time, the length of the pad 10 can be controlled, so that the end of the pad 10 contacts the side of the crucible, thereby driving the pad 10 to move downward. For a crucible with equal upper and lower diameters, a support frame (not shown in the accompanying drawings) needs to be installed at the bottom of the support ring 18 to support the crucible.

[0034] In a further optimized solution, pull rings are respectively installed on two opposite sides of the frame 5. The setting of the pull ring can facilitate the installation and movement of the placement rack, and avoid accidentally touching the crucible on the placement rack to cause burns.

[0036] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
