Description

Sealed dry-type cooling device of calcination crucible

Technical Field

The utility model belongs to laboratory crucible roasting test field, concretely relates to sealed dry-type cooling device of calcination crucible.

Background

The laboratory often uses crucibles to perform roasting tests on particular substances in high temperature furnaces. After the completion of the calcination, in order to prevent the high-temperature substances in the crucible from being oxidized in the air, the calcined substances and the crucible are usually placed in cold water for rapid cooling. For substances which can not contact with water, a layer of coal powder or coke powder is added on the surface layer of the high-temperature substance on the upper part of the crucible after the substances are discharged, and then the crucible is covered or covered. The coal powder or the coke powder is used for generating carbon monoxide by anoxic combustion to form weak reducing atmosphere for cooling.

The water cooling has the advantages of quick cooling, simple operation and more problems. Firstly, a high-temperature crucible discharged from a furnace is instantly thrown into a basin or a cooling container with mineral substances, so that splashing and scalding accidents are easily caused; secondly, when the high-temperature crucible is filled with water, the high-temperature gas can cause the powdery test sample to splash, so that the representativeness and the accuracy of the test sample are reduced; thirdly, the crucible is easy to crack, the test cost is increased, and small particle substances are mixed into a test sample after cracking, so that the test accuracy is influenced. In addition, sample treatment is carried out again in sample filtration, the stoving behind the water-cooling for test cycle is longer, and prior art can't solve above-mentioned technical problem.

A layer of coal powder or coke powder is added on the surface layer of the crucible for protective dry cooling, and carbon monoxide is generated in the test environment, which is not beneficial to health; in addition, impurities such as coal ash are mixed in the test sample, which affects the accuracy of the test.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sealed dry-type cooling device of calcination crucible, aim at solve the problem that exists in the experimental cooling of current crucible calcination.

Therefore, the utility model adopts the following technical scheme:

a sealed dry cooling device for a roasting crucible comprises a support, wherein a sealing platform for placing the crucible is arranged at the top of the support, a raised crucible placing table is arranged at the center of the sealing platform, a combustion table is arranged on one side of the crucible placing table, a temperature measuring tube which vertically extends downwards is connected at the center of the bottom of the crucible placing table, the temperature measuring tube penetrates through the sealing platform, and a thermometer for measuring the temperature of the crucible placing table is arranged in the temperature measuring tube; the upper surface of the sealing platform is provided with an annular sealing water tank along the edge, the sealing platform is buckled with a sealing cover, and the edge of the sealing cover is clamped in the sealing water tank.

Further, the inner edge of the sealed water tank is at least 10mm higher than the outer edge.

Further, the crucible placing table has a thickness of at least 5mm.

Furthermore, the sealing cover is made of glass, acrylic or stainless steel metal materials.

Further, a handle is arranged at the top of the sealing cover.

Further, the height of the bracket is similar to the height of the furnace door of the roasting furnace.

The beneficial effects of the utility model reside in that: taking the crucible out of the furnace after high-temperature roasting, placing the crucible into a specified crucible placing table nearby, igniting inflammable matters (paper or candles) on the burning table, and covering the crucible and the inflammable matters through a sealing cover; because the bottom of the sealing cover is provided with the water seal, air is prevented from entering the sealing cover, and meanwhile, oxygen in the cover is consumed by the comburent; therefore, the high-temperature test sample is prevented from being oxidized, the test sample is cooled in a dry manner in a closed environment, and can be taken out for subsequent tests after proper temperature detection. The device ensures the safety and accuracy of the test; the cooling mode that the traditional high-temperature crucible is filled with cooling liquid or the surface of the crucible is paved with coal powder and coke powder is changed, and the safe, accurate, environment-friendly and green test target is realized.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, a sealed dry cooling device for a roasting crucible comprises a support 1, wherein a sealing platform 8 for placing a crucible 6 is arranged at the top of the support 1, a raised crucible placing table 4 is arranged at the center of the sealing platform 8, a combustion table 7 is arranged at one side of the crucible placing table 4, a temperature measuring tube 9 which extends vertically and downwards is connected at the center of the bottom of the crucible placing table 4, the temperature measuring tube 9 penetrates through the sealing platform 8, and a thermometer for measuring the temperature of the crucible placing table 4 is arranged in the temperature measuring tube 9; the upper surface of the sealing platform 8 is provided with an annular sealing water tank 2 along the edge, the sealing platform 8 is provided with a sealing cover 3 in a buckling manner, and the edge of the sealing cover 3 is clamped in the sealing water tank 2.

The water seal can prevent the external air from entering after the sealing cover 3 is added; a combustion table 7 is arranged inside; before the cover is added, the cover is ignited to consume oxygen in the cover so as to prevent the mineral powder from being oxidized. The inner edge of the sealed water tank 2 is higher than the outer edge by at least 10mm, so that the pressure reduction after oxygen combustion in the cover is prevented, and the sealed water enters the periphery of the crucible placing table 4 along the inner edge.
