Description

TECHNICAL FIELD

[0001] The utility model relates to a crucible technical field, concretely is an anti-impact ceramic crucible. BACKGROUND

[0002] The ceramic crucible is mainly used for melting, heating, evaporating, drying and high-temperature processing in other chemical experiments in the laboratory. They can maintain stability at high temperature, do not react with materials, and are resistant to the erosion of acid, alkali, salt and other chemical substances. In the traditional ceramic crucible, the anti-impact performance is usually poor, and is easy to break or damage in the case of rapid temperature change or external impact. Due to frequent operation, high-temperature molten material, external mechanical impact and other factors, the ceramic crucible has poor anti-impact performance, and there are hidden dangers in safety and reliability. The crucible constantly bears the stress of thermal expansion and cold contraction during heating and cooling, and is easy to break during experimental use, causing danger. SUMMARY

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide an anti-impact ceramic crucible with excellent high-temperature resistance, which can work stably at extremely high temperature and can withstand severe temperature changes and the impact of substances.

[0004] The technical problem to be solved by the utility model is solved by the following technical scheme. An anti-impact ceramic crucible comprises an inner crucible body and an outer crucible body which are coaxially sleeved, an equidistant buffer cavity is formed between the inner crucible body and the outer crucible body, a plurality of anti-impact rib plates are uniformly arranged along the circumference of the crucible body in the equidistant buffer cavity, a plurality of reinforcing ribs are arranged on the outer wall of the outer crucible body, an upper cover is arranged at the upper opening of the outer crucible body, a lifting motor is arranged above the upper cover, the shaft of the lifting motor is vertically downward, and the end of the shaft of the lifting motor is fixedly arranged with the center of the upper cover. The equidistant buffer cavity formed between the inner and outer crucible bodies disperses external impact force, provides uniform support, realizes effective buffering effect, avoids direct transmission to the inner crucible body, enhances the structural strength of the crucible, reduces the risk of breakage of the crucible due to excessive impact force, and improves the overall anti-impact performance of the crucible.

[0005] The anti-impact rib plates disperse the external impact force to different areas, reduce the excessive pressure on a single part, and avoid the situation that the traditional single-layer crucible structure is easy to crack. The outer wall of the outer crucible body is provided with a plurality of reinforcing ribs, which improves the overall strength of the outer crucible body and makes it not easy to deform under external impact. It is more stable when bearing temperature changes or external impact, and will not appear cracks or damage, which improves the durability of the crucible. In a high-temperature or dangerous environment, the lifting motor reduces the difficulty of manual operation, is safe and fast.

[0006] As a further embodiment of this invention, both the inner and outer crucibles are U-shaped. Each crucible includes an elliptical bottom and a cylindrical body connected to the bottom. The cylindrical bodies of the inner and outer crucibles have the same height, and their upper surfaces are flush. The elliptical bottom improves the heat conduction performance of both the inner and outer crucibles, resulting in a more uniform heat distribution during heating. This reduces heat concentration in a localized area, preventing damage to the crucible due to overheating or uneven heating of the material during the experiment.

[0007] As a further embodiment of this invention, a pipe flange is provided at the upper opening of the outer crucible body. The pipe flange mates with the upper cover, and bolt holes are provided on both the pipe flange and the upper cover. The pipe flange and the upper cover are connected by bolts. This effectively prevents leakage of high-temperature gases, steam, or substances during heating and melting, and ensures the sealing and safety of the experimental process in high-temperature or chemical reaction environments.

[0008] As a further improvement of this invention, a boss is provided on the sealing surface of the upper cover, and the outer diameter of the boss is larger than the outer diameter of the upper opening of the outer crucible. The upper cover is in close contact with the outer crucible, effectively preventing material or gas leakage and improving sealing performance.

[0009] As a further embodiment of this invention, the impact-resistant rib is an arc-shaped plate. The inner arc of the arc-shaped plate matches the shape of the outer wall of the inner crucible, and is fixedly installed thereon. The outer arc of the arc-shaped plate matches the shape of the inner wall of the outer crucible, and is also fixedly installed thereon. The close fit between the arc-shaped plate and the crucible body avoids localized stress concentration, and the fit between the arc-shaped plate and the inner and outer crucible bodies ensures uniform stress distribution.

[0010] As a further embodiment of this invention, a support is provided at the lower part of the outer crucible body. The support includes a support ring plate, and three support legs are provided below the support ring plate, with the three support legs evenly distributed around the circumference of the support ring plate. The support evenly distributes the weight of the outer crucible body and the external load, stably supporting the outer crucible body. A heating source is provided below the outer crucible body to facilitate the movement of the heating source.

[0011] As a further embodiment of this invention, the lifting motor is mounted on a horizontal mounting plate, with vertical support plates on both sides of the horizontal mounting plate. The horizontal mounting plate has positioning holes, in which the lifting motor is installed, and the motor shaft passes through the positioning holes. The lifting motor is stably fixed and automatically opens and closes the upper cover during operation.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This ceramic crucible comprises an inner crucible body and an outer crucible body coaxially nested in two layers. An equidistant buffer cavity is formed between the inner and outer crucible bodies. Several impact-resistant ribs are evenly distributed around the circumference of the crucible body within the equidistant buffer cavity. This disperses external impact forces, provides uniform support, and achieves effective buffering, preventing direct transmission to the inner crucible body. Furthermore, it enhances the structural strength of the crucible, reduces the risk of breakage due to excessive impact force, and improves the overall impact resistance of the crucible. The equidistant buffer cavity and impact-resistant ribs between the inner and outer crucible bodies disperse external impact forces to different areas, reducing excessive pressure on a single part and avoiding the tendency for traditional single-layer crucible structures to crack.

[0013] The outer crucible has several reinforcing ribs on its outer wall, improving its overall strength and making it less prone to deformation under impact. It is more stable under temperature changes or external impacts, preventing cracks or damage and enhancing the crucible's durability. An upper cover is located at the top of the outer crucible, with a lifting motor directly above it. The motor shaft is vertically downwards and fixed to the center of the upper cover. The reinforcing ribs on the outer wall reduce the difficulty of manual operation in high-temperature or hazardous environments, ensuring safety and speed. Both the inner and outer crucibles are U-shaped, including an elliptical bottom. This elliptical bottom improves heat conduction, resulting in more even heat distribution during heating.

[0024] Example 1

[0025] As attached Figure 1 - Appendix Figure 3As shown, an impact-resistant ceramic crucible includes a double-layered, coaxially fitted inner crucible body 10 and an outer crucible body 8. A support 1 is provided at the lower part of the outer crucible body. The support includes a support ring plate 102, and three legs 101 are provided below the support ring plate, evenly distributed circumferentially along the support ring plate. The outer crucible body is vertically mounted on the support ring plate, providing stable support. At the start of the experiment, a heating source is placed below the support ring plate according to the heating requirements. After heating is completed, the heating source is removed as needed.

[0026] Both the inner and outer crucibles 10 and 8 are U-shaped. Both include an elliptical bottom, which is fixed to the support ring plate and exposed for heating. When the heating source is activated, it heats the bottom of the crucible. Through heat transfer, the outer crucible is heated while the inner crucible is heated, and the heat is ultimately transferred to the inner crucible 10, heating the material inside to the specified temperature.

[0027] An equidistant buffer cavity 11 is formed between the inner and outer crucible bodies. Twenty impact-resistant ribs 9 are evenly distributed around the circumference of the crucible body within this buffer cavity. These impact-resistant ribs are arc-shaped plates, with the inner arc conforming to the shape of the outer wall of the inner crucible and fixed to it. The outer arc conforms to the shape of the inner wall of the outer crucible and is fixed to it. The entire ceramic crucible is integrally molded during manufacturing, resulting in uniform stress distribution among its components. The impact-resistant ribs provide support and, during thermal expansion and contraction or impact, effectively buffer the received impact force. The inner and outer crucible bodies will not shatter due to sudden impacts. Furthermore, during thermal expansion and contraction, the inner crucible body is pulled by the impact-resistant ribs, preventing deformation.

[0028] In the experiment, when the reaction temperature was set after being heated, heating was stopped when heat preservation was required. The hot air in the equidistant buffer zone could effectively prevent heat loss and maintain the reaction temperature for a longer period of time.

[0029] The outer wall of the outer crucible is provided with three reinforcing ribs 7, which are perpendicular to the impact-resistant rib plate 9. This strengthens the outer crucible body in both the longitudinal and circumferential directions. The internal support force of the impact-resistant rib plate and the external support force of the reinforcing rib cancel each other out to a certain extent, ensuring the crucible is stable under stress while minimizing the weight of the crucible by using a reinforced structure instead of a thicker crucible wall.

[0030] The inner and outer crucibles have an elliptical bottom and a connected cylindrical body. The inner and outer crucibles are the same height, and their upper surfaces are flush. An upper cover 4 is provided at the upper opening of the outer crucible, and a boss is provided on the sealing surface of the upper cover. The outer diameter of the boss is larger than the outer diameter of the upper opening of the outer crucible.

[0031] The outer crucible body is provided with a pipe flange 6 at the upper opening. The pipe flange 6 is fitted with the upper cover 4. The pipe flange 6 and the upper cover 4 are provided with bolt holes. The pipe flange 6 and the upper cover 4 are connected by bolts 5.

[0032] Before use, add the materials to the inner crucible according to the specified ratio, align the upper cover 4 with the nozzle flange 6, and tighten with bolts to form a sealed reaction space. After the reaction is complete, remove the bolts, remove the upper cover, and then transfer the reactants generated from the reaction.

[0033] When the material does not require a sealed reaction, the upper cover 4 does not need to be fitted with the pipe flange 6, and the pipe flange is in an open state, allowing the crucible to be heated.

[0034] Example 2

[0035] Manual handling and assembly of the top cover is time-consuming and labor-intensive. Unlike the manual assembly mentioned above, it can be automatically assembled using a lifting motor.

[0036] A lifting motor 3 is provided directly above the upper cover. The lifting motor shaft is set vertically downward. The lifting motor 3 is installed on a horizontal mounting plate 201. Vertical support plates 2 are provided on both sides of the horizontal mounting plate. Positioning holes are provided on the horizontal mounting plate. The lifting motor is installed in the positioning holes. The lifting motor shaft passes through the positioning holes. The end of the lifting motor shaft is fixedly set to the center of the upper cover.

[0037] When the lifting motor shaft is in the retracted state, it drives the upper cover to a position away from the pipe flange. When the material is added to the inner crucible in proportion, the lifting motor 3 is started. The motor shaft extends downward, driving the upper cover to move downward until it contacts and engages with the pipe flange. The bolt holes are automatically aligned and then fixed and sealed by bolt connection.

[0038] In the description of this specification, the terms "connection," "installation," "fixing," and "setting," etc., are interpreted broadly. For example, "connection" can mean a fixed connection or an indirect connection via an intermediate component without affecting the relationship between components and the technical effect; it can also mean an integral connection or a partial connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
