Description

Technical Field

[0001] The invention relates to the technical field of high-temperature calcining equipment of a crucible furnace, in particular to a high-temperature calcining equipment and a use method thereof. Background Art

[0002] Crucible furnace high temperature calcination equipment is a kind of equipment that can carry out experiments and industrial production under high temperature environment. It can provide stable high temperature heating conditions to meet the needs of material heat treatment, experimental research and production processing. Crucible furnace is mainly used in materials science, chemical industry, metal processing and other fields, and plays a key role in laboratories and industrial production. The equipment heats the material at high temperature to reach the required temperature range to achieve sintering, melting, annealing and other heat treatment processes of the material. Crucible furnace is usually composed of crucible, heating element, insulation material and control system, and has high heating rate and temperature control accuracy.

[0003] According to the announcement number CN113865345A, an energy-saving and environmentally friendly high-temperature calcination device for electrode paste raw materials and a method of using the same are disclosed, including a calcination furnace main body, the outer surface of which is provided with a heat preservation frame, by providing the heat preservation frame, the heat preservation frame adopts a heat preservation material, the internal heat loss during operation of the calcination furnace main body can be reduced, and at the same time, it is convenient for the liquid to carry heat and flow in the heat preservation frame, the front side of the heat preservation frame is fixedly connected to the back side of the fixed plate, the upper surface of the fixed plate is fixedly connected to the lower surface of the connecting pump, the upper surface of the connecting pump is connected to the bottom end of the liquid inlet pipe, and the back side of the liquid inlet pipe is respectively connected to the first connecting pipe and the first connecting pipe. One end of the front side of the two connecting pipes is connected, and the first connecting pipe and the second connecting pipe are both clamped on the front side of the insulation frame. By setting a connecting pump, a liquid outlet pipe, a liquid inlet pipe and a spiral guide plate, the connecting pump applies pressure to the liquid in the storage box and continuously moves downward along the spiral guide plate, so that the heat emitted by the combustion in the combustion chamber can be carried downward, and one end of the back side of the second connecting pipe is connected to the middle hole, and the middle hole is opened on the front side of the connecting block. By setting the connecting block, the high-temperature liquid heated by the combustion chamber flows through the middle hole to realize the heating of the connecting block, and the heating of the preheating zone inside the calcining furnace body can be realized. The inner wall of the connecting block is provided with a placement cavity.

[0004] By adopting the above technical scheme, while the calcining furnace main body calcines the raw materials, the volatile impurities in the raw materials in the high-temperature calcining zone flow directly upward into the combustion chamber through the gas pipe, and the combustion chamber ignites the gas. At the same time, a large amount of heat generated by the combustion is driven downward by the liquid driven by the connected pump to the raw materials at the corners below the calcining furnace main body. The raw materials at the corners can be heated by the heat carried by the liquid, thereby reducing the temperature difference between the corners of the calcining furnace main body and the raw materials near the upper plate and the lower plate, and at the same time reducing the probability of volatile impurities and gases in the high-temperature calcining zone contacting the raw materials in the preheating zone upward, reducing the probability of impurities adhering to the low-temperature raw materials, making the overall calcination degree of the raw material calcination process more uniform, and reducing the probability of overburning or insufficient calcination. However, in the above technical scheme, during the process of high-temperature calcination using the high-temperature calcination equipment, the high-temperature calcination equipment usually radiates heat to the outside, which leads to the loss of heat energy during use. Heat loss means waste of energy, which will lead to a decrease in the energy efficiency of the calcination equipment, thereby increasing production costs. At the same time, heat loss may lead to insufficient calcination temperature, affecting product quality and production efficiency. Summary of the invention

[0047] Embodiment 3

[0048] See also Figure 1-6The specific implementation method of this embodiment is as follows: first, the staff transports the device to a suitable use position, then turns on the power of the air pump 304 and the water pump 9 to enable them to be stably powered on, then the staff places the material to be calcined into the inside of the calcining furnace body 1, and then injects a proper amount of water into the water storage tank 7 through the water injection pipe 8, then the staff installs the support plate 401 and the air extraction device on the support plate 401 to the top of the calcining furnace body 1 through the limit column 402, and then after the support plate 401 is installed, the staff squeezes the support plate 401 through the squeezing ring 403, The staff then manually rotates the threaded pin 405 on the fixing ring 404, and the threaded pin 405 can move to the outside of the fixing ring 404 when rotating.

When the calcining furnace body 1 is calcining the internal material, the heat will be in a state of rising. This is because the heat generated during the calcining process will cause the air temperature inside the equipment to rise, making the hot air less dense than the surrounding cold air, so the hot air will rise, and then the vacuum pump 304 is turned on. After the vacuum pump 304 is turned on, suction can be generated. The vacuum pump 304 can extract a part of the heat that rises to the top of the calcining furnace body 1. The extracted heat can be transmitted through the multi-way pipe 305.
