Description

Technical Field

[0001] The utility model relates to the technical field of crucibles, in particular to a titanium-zirconium composite crucible device. Background Technique

[0002] A crucible is a cup-shaped vessel used in laboratories for high-temperature heating of solids. The production raw materials of crucibles can be generally summarized into three types. One is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin-based framework clinker. In the prior art, crucibles are also made of titanium-zirconium alloy.

[0003] However, in the existing technology, the outer surface of the titanium-zirconium composite crucible is directly in contact with the outside air, which results in a lower temperature on the outer surface of the crucible compared to the inner surface. This temperature difference may cause the temperature inside the crucible to be affected by the outside and become lower, thereby resulting in a poor overall heating effect of the crucible. Therefore, it does not meet the existing requirements, and for this reason, we propose a titanium-zirconium composite crucible device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a titanium-zirconium composite crucible device to solve the problems mentioned in the above background technique, that is, the outer surface of the existing composite crucible is directly in contact with the outside air, which results in a lower temperature on the outer surface of the crucible compared to the inner surface. This temperature difference may cause the temperature inside the crucible to be affected by the outside and become lower, thereby resulting in a poor overall heating effect of the crucible.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A titanium-zirconium composite crucible device, including a titanium-zirconium alloy crucible layer. At the middle of the four sides of the titanium-zirconium alloy crucible layer, a connecting plate is fixedly connected. The four sides of the connecting plate are fixedly connected with an outer thermal insulation layer. A sealing cover is placed on the upper ends of the outer thermal insulation layer and the titanium-zirconium alloy crucible layer. An air cavity is provided inside the sealing cover. Through holes are provided at the bottom ends on both sides of the air cavity. A main air outlet is provided through the middle of the upper end of the air cavity. An air inlet is provided through the middle of the lower end of the air cavity. The upper end of the main air outlet is connected with a hot air outflow mechanism.

[0006] Preferably, ventilation holes are provided through both sides of the connecting plate.

[0007] Preferably, a gap cavity is provided between the outer thermal insulation layer and the titanium-zirconium alloy crucible layer, and the bottom end of the gap cavity is communicated with the outside.

[0008] Preferably, the hot gas outflow mechanism includes a circulation column fixedly connected to the upper end of the sealing cover. An air outlet cavity is provided inside the circulation column. A hot gas outlet is provided through the middle of the upper end of the air outlet cavity. An outer cavity air port is provided through the lower end of the air outlet cavity. A blocking ball is plugged on the upper side of the outer cavity air port. A pulling column is fixedly connected to the middle of the upper end of the blocking ball. Springs are connected around the upper end of the blocking ball. The upper ends of the springs are connected to the upper end inside the air outlet cavity.

[0009] Preferably, elastic sheets are fixedly connected to both sides of the middle of the pulling column. Clamping blocks are fixedly connected to both sides of the bottom end of the hot gas outlet.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. In the process of hot gas flowing in the gap cavity and the air cavity, the outer surface of the titanium-zirconium alloy crucible layer and the inner surface of the outer thermal insulation layer are continuously heated. At the same time, after the hot gas enters the air cavity, the hot gas heats the overall sealing cover. In summary, the settings of the gap cavity and the air cavity enable the hot gas to continuously increase the temperature of the components around the titanium-zirconium alloy crucible layer, so that the temperatures of the components around the titanium-zirconium alloy crucible layer and the titanium-zirconium alloy crucible layer itself are kept consistent, thereby realizing the heat preservation effect on the titanium-zirconium alloy crucible layer and avoiding the problem of poor heating effect caused by inconsistent temperatures on the inner and outer surfaces of the crucible.

[0012] 2. In the present utility model, the gas directly runs out from the air inlet in the middle of the bottom end of the sealing cover, so that the gas will push the blocking ball on the outer cavity air port upward from the main air outlet. At this time, the blocking ball moves upward to squeeze the stretching elastic force of the upper spring, and the excess hot gas will enter the air outlet cavity from the outer cavity air port upward and finally flow out from the hot gas outlet at the upper end of the air outlet cavity, avoiding the crucible from being cracked or damaged due to excessive air pressure and temperature.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please refer to Figures 1 to 3 , an embodiment provided by the present invention: A titanium-zirconium composite crucible device includes a titanium-zirconium alloy crucible layer 9. A connecting plate 4 is fixedly connected to the middle of the periphery of the titanium-zirconium alloy crucible layer 9. An outer thermal insulation layer 2 is fixedly connected to the periphery of the connecting plate 4. A sealing cover 1 is placed on the upper ends of the outer thermal insulation layer 2 and the titanium-zirconium alloy crucible layer 9. An air cavity 8 is provided inside the sealing cover 1;

[0019] Through a circulation hole 7 penetrating through the bottom ends on both sides of the air cavity 8, a main air outlet 11 penetrating through the middle of the upper end of the air cavity 8, and an air inlet 10 penetrating through the middle of the lower end of the air cavity 8, and a hot gas outflow mechanism 3 is connected to the upper end of the main air outlet 11. This setting enables the gases inside the gap cavity 6 on the inner side of the outer thermal insulation layer 2 and the air cavity 8 inside the sealing cover 1 to communicate and cooperate.

[0020] Through ventilation holes 5 penetrating through both sides of the connecting plate 4, a gap cavity 6 is provided between the outer thermal insulation layer 2 and the titanium-zirconium alloy crucible layer 9. The bottom end of the gap cavity 6 is communicated with the outside. This setting enables the gap cavity 6 to communicate with the outside, and at the same time enables hot gas to continuously enter the gap cavity 6;

[0021] When the overall crucible device is placed on a furnace for heating, the gas generated by the furnace will penetrate through the bottom end between the outer thermal insulation layer 2 and the titanium-zirconium alloy crucible layer 9 and enter the gap cavity 6. Then, the gas inside the gap cavity 6 flows upward through the ventilation holes 5 on the connecting plate 4, and the hot gas continuously enters the air cavity 8 from the circulation holes 7 at the lower ends on both sides of the sealing cover 1. Then, the gas inside the air cavity 8 will continuously enter the titanium-zirconium alloy crucible layer 9 from the air inlet 10 at the lower end. This setting enables the hot gas to continuously enter the inside of the titanium-zirconium alloy crucible layer 9, making the temperature inside the titanium-zirconium alloy crucible layer 9 not easy to decrease;

[0022] During the flow of hot gas in the gap chamber 6 and the air chamber 8, the outer surface of the titanium-zirconium alloy crucible layer 9 and the inner surface of the outer thermal insulation layer 2 are continuously heated. At the same time, after the hot gas enters the air chamber 8, the hot gas heats the overall sealing cover 1. In summary, the settings of the gap chamber 6 and the air chamber 8 enable the hot gas to continuously increase the temperature of the components around the titanium-zirconium alloy crucible layer 9, so that the temperatures of the components around the titanium-zirconium alloy crucible layer 9 and the titanium-zirconium alloy crucible layer 9 itself are kept consistent, thereby realizing the heat preservation effect on the titanium-zirconium alloy crucible layer 9.

[0023] The hot gas outflow mechanism 3 includes a circulation column 301 fixedly connected to the upper end of the sealing cover 1. An air outlet chamber 304 is provided inside the circulation column 301. A hot gas outlet 302 penetrates through the middle of the upper end of the air outlet chamber 304. An outer chamber air port 305 penetrates through the lower end of the air outlet chamber 304. A blocking ball 306 is plugged on the upper side of the outer chamber air port 305. A pulling column 303 is fixedly connected to the middle of the upper end of the blocking ball 306. Springs 307 are connected around the upper end of the blocking ball 306. The upper ends of the springs 307 are connected to the upper end inside the air outlet chamber 304. The stretching elastic force of the springs 307 presses the blocking ball 306 downward, so that the lower end of the blocking ball 306 blocks the outer chamber air port 305. This setting makes the air outlet chamber 304 inside the circulation column 301 in a non-ventilated state under normal conditions;

[0024] When the gas inside the titanium-zirconium alloy crucible layer 9 gradually increases, the internal air pressure continuously increases. Then the gas will directly run out from the air inlet 10 in the middle of the bottom end of the sealing cover 1. As a result, the gas will push the blocking ball 306 on the outer chamber air port 305 upward from the main air outlet 11. At this time, the upward movement of the blocking ball 306 squeezes the stretching elastic force of the upper spring 307. The excess hot gas will enter the air outlet chamber 304 from the outer chamber air port 305 upward and finally flow out from the hot gas outlet 302 at the upper end of the air outlet chamber 304;

[0025] Elastic pieces 308 are fixedly connected to both sides of the middle of the pulling column 303. Clamping blocks are fixedly connected to both sides of the bottom end of the hot air outlet 302. When the overall hot air outflow mechanism 3 is in use, the user manually pulls the pulling column 303 at the upper end of the blocking ball 306, so that the pulling column 303 drives the blocking ball 306 at the lower end to move upward. The elastic pieces 308 on both sides of the pulling column 303 also move upward. Then the elastic pieces 308 gradually move upward to the upper end of the clamping block at the bottom end of the hot air outlet 302, and the elastic pieces 308 are clamped at the upper end of the clamping block. This enables the overall pulling column 303 and the blocking ball 306 to be displaced and positioned at the upper end of the air outlet cavity 304. Furthermore, the blocking ball 306 no longer blocks the outer cavity air port 305, so that gas continuously escapes from the main air outlet 11 and the air inlet 10 at the lower end of the outer cavity air port 305. This setting prevents gas from accumulating inside the titanium-zirconium alloy crucible layer 9, and thus avoids the crucible from cracking or being damaged due to excessive air pressure and temperature.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
