Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixed material drying technology, and in particular to an energy-saving hydrothermal device. Background Technology
[0002] The production process of titanium carbide cemented carbide involves three important steps: first, the raw materials are mixed and mixed with adhesive; second, the mixed materials are pressed into shape; and finally, they are sintered in a vacuum. After being removed from the furnace, they are selected and cleaned to produce qualified titanium carbide cemented carbide products.
[0003] To prevent oxygen from entering the raw material mixing process, the mixture is usually mixed in an alcohol solution. After mixing, the alcohol is distilled out through a drying pot. Then, the dried mixed raw materials are mixed with glue in a certain proportion. Finally, the mixed material with glue is spread on the workbench and dried with an industrial fan. After drying, the powder of the same particle size is sieved out and enters the pressing stage.
[0004] In the process of distilling alcohol, water is usually heated electrically and then transferred to a drying pot. However, alcohol evaporation requires a temperature above 70°C. To prevent the drying pot from burning dry, water is continuously flowing, resulting in a significant waste of hot water. Secondly, the process of using a fan to dry the mixture generates a lot of powder, causing substantial dust pollution in the workshop, affecting environmental hygiene, and in severe cases, impacting the mixture's proportions and thus the quality of the alloy. Utility Model Content
[0005] This utility model provides an energy-saving hydrothermal device to solve the problems of energy waste during alcohol evaporation from mixed materials and the impact on the environment and quality during drying.
[0006] This utility model provides an energy-saving hydrothermal device, including: a water tank, a drying pot, and a drying platform. The water tank is connected to the bottom of the drying pot through a pipe. The bottom of the drying pot is provided with a heating chamber. The drying pot is provided with a jacket that communicates with the heating chamber. A heating device is provided in the heating chamber. The hot water in the jacket flows through a pipe to the lower end of the drying platform and then flows back to the water tank through a return water pipe. The drying platform dries the mixture by absorbing heat from the hot water.
[0007] Preferably, a U-shaped pipe is laid under the drying table, the upper end of the jacket is connected to the U-shaped pipe through a pipe, and the U-shaped pipe is connected to the water tank through a return water pipe.
[0008] Preferably, a hot water chamber is provided below the drying table, the upper end of the jacket is connected to the hot water chamber through a pipe, and the hot water chamber is connected to the water tank through a return water pipe.
[0009] Preferably, the water tank is provided with a water inlet pipe, and the water tank is provided with a float valve connected to the water inlet pipe.
[0010] Preferably, the heating device is an electric heater.
[0011] Preferably, the water tank is provided with an overflow outlet, and the horizontal position of the overflow outlet is higher than the horizontal position of the outlet of the return water pipe.
[0012] Preferably, the pipe is wrapped with an insulation layer.

[0015] Preferably, both the drying pot and the drying table are provided with supports at their lower ends.
[0016] Compared with existing technologies, in this invention, the heating device heats the water from the water tank, and then the hot water flows into the jacket, and then from the jacket to the bottom of the drying table. The hot water raises the temperature of the drying table, thereby slowly drying the mixture spread on the drying table. The hot water then flows back into the water tank through the return pipe, raising the water temperature in the tank and reducing the energy consumption of the heating device. In this structural design, the hot water discharged from the drying pot is used to slowly dry the mixture, eliminating the need for an industrial fan to blow on the mixture, saving energy, avoiding air pollution from the wind, and not affecting the environmental hygiene of the workshop. This ensures the proportion of the mixture and guarantees the production quality of the alloy. Secondly, the water discharged from the drying pot returns to the water tank through the return pipe, and then returns from the water tank back to the drying pot, reusing the hot water and saving costs. Thirdly, by heating the water to flow to the bottom of the drying table and then back into the water tank, no water pump equipment is needed in this process, reducing investment costs and energy consumption.

[0024] See attached document Figure 1 and attached Figure 3 This embodiment provides an energy-saving hydrothermal device, including: a water tank 1, a drying pot 2, and a drying platform 3. The water tank 1 is connected to the bottom of the drying pot 2 via a pipe. The bottom of the drying pot 2 is provided with a heating chamber 4. The drying pot 2 contains a mixture mixed with alcohol. The drying pot 2 is provided with a jacket 5 connected to the heating chamber 4. A heating device is provided in the heating chamber 4. Hot water from the jacket 5 flows through a pipe to the lower end of the drying platform 3 and then flows back to the water tank 1 through a return water pipe 6. The drying platform 3 dries the mixture by absorbing heat from the hot water. In this invention, water from the water tank 1 flows into the heating chamber 4 by gravity. The heating device heats the water, and then the hot water flows into the jacket 5 and then from the jacket 5 to the bottom of the drying platform 3. The hot water raises the temperature of the drying platform 3, thereby slowly drying the mixture spread on the drying platform 3. The hot water then flows into the water tank 1 along the return water pipe 6, raising the water temperature in the water tank 1 and reducing the energy consumption of the heating device. In this structural design, the hot water discharged from the drying pot 2 is used to slowly dry the mixture, eliminating the need for industrial fans to blow on it. This saves on fan electricity costs, avoids air pollution from the airflow, and maintains the cleanliness of the workshop, ensuring the correct proportions of the mixture and guaranteeing the quality of the alloy production. Secondly, the water discharged from the drying pot 2 returns to the water tank 1 via the return pipe 6, and then returns from the water tank 1 back to the drying pot 2, reusing the hot water and saving costs. Thirdly, by heating the water, it flows to the bottom of the drying table 3 and then back into the water tank 1. This process eliminates the need for water pumps, reducing cost and energy consumption.

The drying table 3 is rectangular in shape, and the U-shaped pipe 7 is located in the cavity of the drying table 3.

A float valve 9 connected to the water inlet pipe 8 is provided inside the water tank 1. When the water in the water tank 1 drops to a predetermined water level due to evaporation, the float valve 9 opens the water inlet pipe 8, and tap water replenishes the water tank 1.
[0028] As another embodiment of this utility model: the pipe is wrapped with an insulation layer, and this structural design can effectively reduce heat loss during the flow of hot water.
[0029] As another embodiment of this utility model: the outer side of the water tank 1 is provided with a heat insulation layer, and this structural design can effectively reduce the heat loss of the water tank 1.

[0031] As another embodiment of this utility model: the water tank 1 is provided with an overflow outlet, the horizontal position of which is higher than the horizontal position of the outlet of the return water pipe 6. When the water in the water tank 1 expands due to temperature rise, causing the water level to rise, the excess water will be discharged from the overflow outlet.
