[0027] The device introduces water and boron carbide powder into the mixing box 1 through the water inlet 2 and the feed port 3 respectively, and uses the stirring rod 4 to stir the slurry to ensure that the water and boron carbide powder are fully mixed and the water washing effect is improved.

[0029] A gas flow meter is provided between the gas storage tank 7 and the exhaust pipe 5 for accurately measuring and controlling the gas flow entering the mixing box 1 to meet the requirements under different process conditions.

At the same time, the top of the mixing box 1 is also provided with an observation window to facilitate the operator to observe the state of the slurry during the mixing process.

[0031] This application includes the following steps during use

[0032] Preparation stage: Check whether all parts of the device are intact, ensure that the water inlet 2, feed inlet 3, exhaust pipe 5, etc. are tightly connected, adjust the water temperature of the water inlet 2 and the steam volume of the steam boiler 8 according to the process requirements, and set the flow value of the gas flow meter.

[0033] Feeding stage: Add an appropriate amount of water into the mixing box 1 through the water inlet 2, and at the same time add boron carbide powder into the mixing box 1 through the feed inlet 3. Pay attention to controlling the feeding speed to avoid the slurry being too thick or too thin.

[0034] Stirring stage: Start the driving device to make the stirring rod 4 start to rotate and fully stir the slurry. At the same time, open the air outlet of the steam furnace 8 and the air outlet of the vacuum pump 9, inject steam into the slurry and extract excess gas. During the stirring process, observe the slurry state through the observation window and adjust the stirring speed and gas flow as needed.

[0035] Monitoring and adjustment stage: During the stirring process, the temperature and pH of the slurry are monitored in real time, and the water temperature of the water inlet 2 and the steam volume of the steam furnace 8 are adjusted according to the data fed back by the sensor to ensure the uniformity of the slurry mixing and the precise control of the reaction conditions.

[0036] Discharging stage: When the slurry reaches the predetermined washing effect, turn off the steam furnace 8 and the vacuum pump 9, stop stirring, open the discharge port at the bottom of the mixing box 1, and discharge the slurry out of the device for subsequent processing.

[0037] Cleaning and maintenance stage: After each use, clean and maintain the device to ensure that all parts are clean and intact. Regularly check the wear of easily worn parts such as the stirring rod 4 and the exhaust pipe 5, and replace severely worn parts in time.

[0038] The present application can more effectively promote the mixing of water and boron carbide powder by optimizing the design and stirring process of the stirring rod 4, ensuring that each powder can fully contact the water, thereby improving the efficiency of water washing. After the feeding and water addition are completed, the hot steam is controlled by the high-temperature steam valve 10 to achieve the heating of the slurry mixture to achieve the optimal water washing temperature. A vacuum pump 9 is provided on one side of the stirring box 1 to extract the steam in the device in time, and compressed air is introduced into the stirring rod 4. The two-way opening design at the end fully increases the gas-liquid contact surface and improves the water washing effect.

[0039] The temperature sensor and pH sensor inside the device can monitor the temperature and pH of the slurry in real time, allowing the operator to adjust the water temperature of the water inlet 2 and the steam volume of the steam furnace 8 in time according to process requirements to ensure that the slurry is mixed and reacted under optimal conditions. This precise control not only improves the water washing effect, but also helps to reduce powder loss or impurity residue caused by improper conditions.

[0040] The insulation layer design of the outer wall of the mixing box 1 effectively reduces the heat loss during the mixing process, maintains the stability of the slurry temperature, and thus reduces energy consumption. By optimizing the water washing process and improving the water washing efficiency, this device reduces the number of repeated water washings, saves water resources and time costs, and improves the overall economic benefits.

[0041] The observation window on the top of the device allows the operator to observe the state of the slurry during the mixing process at any time and adjust the operating parameters in time, which improves the convenience of operation. At the same time, the overall design of the device takes into account the safety of operation, such as ensuring that all components are tightly connected and avoiding leakage, providing a safer working environment for the operator.

[0042] This device can be adjusted according to different process requirements. For example, the gas flow rate entering the mixing box 1 can be controlled by adjusting the flow value of the gas flow meter to meet the water washing requirements under different conditions. This flexibility and adaptability enable this device to be widely used in the water washing process of various boron carbide powders, providing customized solutions for users in different fields.

[0043] By improving water washing efficiency and reducing the number of repeated water washings, this device helps reduce water waste and pollutant emissions, meeting the requirements of environmental protection and sustainable development. At the same time, the optimized water washing process also helps to improve the purity and quality of boron carbide powder, providing higher-quality raw materials for the production and application of downstream products.
