Description

Technical Field

[0001] The present application relates to the technical field of chemical instruments and equipment, and in particular to a high-strength silicon carbide crucible. Background Art

[0002] Crucible is an important component of chemical instruments. It is a container for melting and refining metal liquids and for heating and reacting solids and liquids. It is the basis for ensuring the smooth progress of chemical reactions.

[0003] Chinese patent publication number CN218097184U discloses a corrosion-resistant silicon carbide crucible. A connecting ring is fixedly provided on the outer side of the crucible body, and the lower end face of the connecting ring is connected to a support column and a bottom ring. A first clamping ring and a second clamping ring are provided on the outer side of the crucible body. A top cover is movably provided on the upper end of the crucible body, and a temperature measuring hole is opened on one side of the upper end face of the top cover.

[0004] Regarding the above-mentioned related technologies, when melting metal, the metal will turn into molten metal and other gases. Under the action of high temperature, the temperature of the crucible body and the top cover will be relatively high. If the operator directly touches the top cover at this time, there is a risk of being burned, which is insufficient. Utility Model Content

[0005] In order to prevent the operator from being burned by direct contact with the crucible body, the present application provides a high-strength silicon carbide crucible.

[0006] The present application provides a high-strength silicon carbide crucible using the following technical solutions:

[0007] A high-strength silicon carbide crucible comprises a crucible body, a support frame is provided on the outer side of the crucible body, the support frame comprises a positioning ring directly in contact with the crucible body, a plurality of support rods are fixedly connected below the positioning ring, a bottom ring is commonly connected below the plurality of support rods, a top cover is provided on the crucible body, the top cover is rotatably connected to the crucible body, an ejector rod for controlling the opening and closing of the top cover is provided on the crucible body, and an adjusting member for controlling the lifting and lowering of the ejector rod is provided on the crucible body.

[0008] By adopting this technical solution, the support frame prevents the crucible from tipping over, while the top cover prevents molten metal from splashing out and potentially injuring workers. The provision of an ejector rod and adjustment member allows workers to open and close the top cover without directly touching it, and to control its degree of opening and closing, reducing the risk of burns from high temperatures.

[0009] Optionally, the adjusting member includes two adjusting rods, the middle parts of the two adjusting rods are cross-arranged and rotatably connected, a section of the two adjusting rods relative to the intersection is arc-shaped, and they are jointly sleeved on the outside of the crucible body, and the two adjusting rods are in contact with each other near the end of the crucible body and are located at the bottom of the ejection rod.

[0010] By adopting the above technical solution, a worker grips the other end of the adjustment rod relative to the arc segment, and the end of the arc segment of the adjustment rod contacts the adjustment rod. The worker lifts the adjustment rod. The adjustment rod supports the ejection rod. As the ejection rod at one end of the top cover rises and lifts the top cover, the top cover can be opened without the worker directly touching the top cover, reducing the possibility of burns to the worker.

[0011] Optionally, a clamping ring is provided on the outer wall of the crucible body, a blocking ring is provided in the vertical direction on the side of the clamping ring away from the crucible body, and the arc sections of the two adjusting rods are provided on the clamping ring.

[0012] By adopting this technical solution, the adjustment member can be placed on the retaining ring. When in use, the adjustment member can be directly lifted upward, thereby raising the ejector rod, thereby achieving the effect of opening and closing the top cover. In addition, the two staggered adjustment rods can be used as handles. When the adjustment rods are lifted upward, the curved sections of the adjustment rods engage the outer side of the crucible body, and the operator can lift it up to remove the crucible body. The retaining ring prevents the adjustment member from sliding.

[0013] Optionally, both ends of the ejector rod are provided with a protrusion with a diameter larger than the cross-section of the ejector rod, and one end of the crucible body is provided with a connecting frame, the ejector rod is passed through the connecting frame, and the lower surface of the protrusion close to the top cover contacts the upper surface of the connecting frame.

[0014] By adopting this technical solution, the ejector rod can be placed on the connecting frame. The provision of the protrusion increases the contact area between the ejector rod and the adjusting member, making it easier to achieve contact and lifting of the adjusting rod. At the same time, the connecting frame provides a stable running track for the adjusting rod, keeping it stable during movement.

[0015] Optionally, ends of the two adjusting rods away from the crucible body are both provided with heat-proof pads.

[0016] By adopting the above technical solution, the temperature of the crucible body is relatively high, the adjusting member itself has a certain thermal conductivity, and the design of the heat-proof pad can reduce the heat transferred by the adjusting member, further reducing the possibility of burns to the user.

[0017] Optionally, a spring is connected to the other end of the two adjusting rods relative to the intersection of the adjusting rods, and both ends of the spring are fixedly connected to the two adjusting rods respectively.

[0018] By adopting the above technical solution, under normal circumstances, the spring applies thrust to both sides, and it is actually measured that the arc sections of the two adjusting rods are pressed against each other, preventing the adjusting member from loosening and failing to effectively contact the ejection rod.

[0019] Optionally, a pull rope is fixedly provided on the outer edge of the top cover and close to the side rotatably connected to the crucible body, and the pull rope is suspended in the air.

[0020] By adopting the above technical solution, after the adjusting member pushes up the ejection rod, the top cover is lifted up. If the operator wants to fully open the top cover, he can pull the pull rope downward to make the top cover continue to flip over, thereby achieving full opening of the top cover.

[0021] Optionally, the top cover is provided with ventilation holes for ventilation.

[0022] By adopting the above technical solution, the gas generated by smelting the metal can flow out from the vent hole, preventing the accumulation of gas inside the crucible body and causing the molten metal to splash after the lid is opened, thereby improving the safety of the crucible.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The support frame design provides a stable support for the crucible body, preventing the crucible from tipping over during use. The top cover, ejector rod, and adjustment piece design make the top cover easy and quick to open and close, greatly improving the convenience of experimental operation, while preventing the operator from directly contacting the top cover, reducing the risk of burns.

[0025] 2. The clamping ring, blocking ring, and connecting frame provide a stable running track for the adjustment rod, keeping it stable during movement without deflection or slippage. This ensures operational accuracy, while the connecting frame supports the ejector rod and improves stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application discloses a high-strength silicon carbide crucible. Figure 1 A high-strength silicon carbide crucible includes a crucible body 1, which is shaped like a truncated cone, wide at the bottom and narrow at the top. A support frame 2 is provided on the outside of the crucible body 1. The support frame 2 includes a positioning ring 3 that directly contacts the crucible body 1. Because the crucible body 1 is a truncated cone, the positioning ring 3 can support the crucible body 1 and prevent it from falling off. Two support rods 4 are fixedly connected below the positioning ring 3. The lower ends of the two support rods 4 are connected to a bottom ring 5. The two support rods 4 are evenly arranged along the circumference of the bottom ring 5.

[0031] Reference Figure 1 and Figure 2 A clamping ring 6 is provided on the outer wall of the crucible body 1 and above the positioning ring 3. The clamping ring 6 is arranged in the circumferential direction of the crucible body 1. A blocking ring 7 is provided on the side of the clamping ring 6 away from the crucible body 1, and the blocking ring 7 is arranged in the vertical direction. An adjusting member for controlling the lifting and lowering of the ejector rod 14 is provided above the clamping ring 6. The adjusting member includes two adjusting rods 8. The middle parts of the two adjusting rods 8 are cross-arranged and rotatably connected. The two adjusting rods 8 are both arc-shaped relative to one side of the intersection, and are jointly sleeved on the outer side of the crucible body 1 and contact the upper surface of the clamping ring 6. The two adjusting rods 8 are straight rods relative to the other side of the intersection and are arranged away from the crucible body 1. The ends of the straight rod sections of the two adjusting rods 8 are sleeved with heat-proof pads 9. The straight rod sections of the two adjusting rods 8 and the side close to the intersection are connected with springs 10, and the two ends of the spring 10 are fixedly connected to the two adjusting rods 8 respectively.

[0032] Reference Figure 1 A top cover 11 is provided on the top of the crucible body 1, and a vent hole 12 for air permeability is provided on the top cover 11. A connecting frame 13 is provided at one end of the top of the crucible body 1. The connecting frame 13 is U-shaped, and a through hole (not shown in the figure) is provided at the bottom of the connecting frame 13. An ejector rod 14 for controlling the opening, closing, and lifting of the top cover 11 is passed through the through hole (not shown in the figure). The two adjusting rods 8 are in contact with each other near the end of the crucible body 1 and are located at the bottom of the ejector rod 14. Both ends of the ejector rod 14 are fixedly connected with a protrusion 15. The two protrusions 15 are cylindrical, and the diameter of the cross section is larger than the diameter of the cross section of the ejector rod 14. The lower surface of the protrusion 15 near the top cover 11 contacts the upper surface of the connecting frame 13.

[0033] Reference Figure 1One end of the top cover 11 is provided with a plug-in block (not shown) for mating with the connecting frame 13. The top cover 11 is rotatably connected to the connecting frame 13 via the plug-in block (not shown). A protrusion 15 above the ejector rod 14 supports the lower surface of the plug-in block. A pull rope 16 is fixed to the outer edge of the plug-in block away from the crucible body 1, and the other end of the pull rope 16 is suspended in the air.

[0034] The implementation principle of a high-strength silicon carbide crucible in an embodiment of the present application is as follows: when in use, the operator clamps the heat-proof pad 9 of the adjusting rod 8 and lifts the adjusting rod 8 upward. The end of the adjusting rod 8 supports the ejection rod 14 to lift up. Since the top cover 11 is rotated and connected, the top cover 11 is opened. If the operator wants to increase the opening degree of the top cover 11, he only needs to pull the pull rope 16 downward to fully open the top cover 11.

[0035] In addition, the two adjusting rods 8 can serve as handles of the crucible body 1. Due to the function of the support frame 2, the crucible body 1 is fixed. When the crucible body 1 is to be picked up, the operator needs to forcefully expand the two adjusting rods 8 outward. Since the two adjusting rods 8 are staggered, the arc sections of the two adjusting rods 8 can be pressed against each other and stuck on the outside of the crucible body 1. Then the operator can lift the crucible body 1 up to take it down.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
