In addition, traditional stirring equipment is pure mechanical stirring, and the materials are prone to layering and sedimentation. The conductive ions cannot be fully replaced and separated in the materials, resulting in unclean washing or the need for too many washing times, wasting a large amount of pure water resources. Content of the Utility Model

[0054] Each component in the mixing and stirring device of the present utility model constitutes a stirring and mixing system, a slurry negative pressure concentration system and a drainage system. The working processes and principles of each system are as follows:
[0055] 1. Stirring and mixing system
[0056] In the mixing and stirring device of the present utility model, the stirring paddle, the feed inlet, the purified water inlet, the motor, the speed reducer and the stirring shaft air inlet chamber jointly constitute the stirring and mixing system. The specific working mode is as follows: The raw material slurry produced is transported to the inner slurry kettle through a diaphragm pump or the powder is added into the kettle through the feed inlet. After reaching the appropriate weight, the feed inlet is closed. The water control valve on the purified water inlet is opened, and an appropriate amount of purified water is injected. The motor is started, and the stirring paddle connected through the coupling rotates, driving the material slurry and the purified water to be stirred together or multiple materials to be mixed.
[0057] During the stirring process, the nozzle on the stirring shaft air inlet chamber is communicated with compressed air. The compressed air reaches the air inlet chamber through the nozzle, then reaches the paddle blades of the stirring paddle through the hollow air pipe of the stirring shaft, and is discharged through the air outlet holes. At this time, under the action of the rotation of the stirring paddle, the compressed air forms dispersed small bubbles for aeration. By using the disordered mixing and friction cleaning of the bubbles plus the traditional mechanical stirring system, the material powder raw materials and pure water are fully replaced and cleaned through aeration in the inner slurry kettle. The small bubbles coming out of the air outlet of the paddle blade continuously combine into large bubbles during the process of rotating and rising. This process fully decomposes the agglomerated material particles and the conductive ions entrained in the agglomerated particles and dissolves them in the pure water liquid to form a mixed solution.
[0058] Numerous diffusely rising small bubbles simultaneously apply an upward force to the material in the liquid, effectively preventing the drawback of rapid sedimentation of the material in the case of separate mechanical stirring. The material can be in a suspended state in the liquid, mixed more evenly, stirred more fully, effectively avoiding the stratification of materials with different particle sizes, and obtaining better stirring and mixing quality.
[0059] The conductive ions pass through the pores of the solid-liquid separation cloth sleeve and the filtrate inner tank in the mixed liquid through Brownian motion, making the slurry outside the filtrate inner tank gradually tend to the equilibrium of the conductive ion concentration (the conductive ions and water molecules are very small and can pass through the micro-gaps of the filter cloth, while the material particles are very large and cannot pass through). This process of transporting the concentration difference is a relaxation process tending to the thermal equilibrium state and conforms to the entropy-driven process.
[0060] 2. Slurry negative pressure concentration system
[0061] In the mixing and stirring device of the present utility model, the slurry inner kettle, the solid-liquid separation cloth sleeve, the filtrate inner tank, the waste water outer kettle, the discharge butterfly valve, the switch valve and the vacuum pump form a slurry negative pressure concentration system. The solid-liquid separation cloth sleeve is embedded in the filtrate inner tank to form the slurry inner kettle. For the slurry mixture after mixing and stirring, the conductive ions, water molecules and ultra-fine material particles in it pass through the solid-liquid separation cloth sleeve and are separated by the cloth sleeve into two spaces, namely the slurry inner kettle and the waste water outer kettle. At this time, the switch valve at the lower part of the waste water outer kettle is opened, and at the same time the vacuum pump is started. The waste liquid containing conductive ions quickly enters the waste water tank under the action of gravity and the suction force of the vacuum pump. At this time, the liquid level of the slurry inner kettle continuously drops, and at the same time the solid content concentration of the slurry continuously increases. The stirring paddle slowly rotates, and the air outlet on the paddle continuously discharges air to prevent blockage of the holes. Until the slurry concentration reaches the appropriate set value, the discharge valve is opened, and the concentrated slurry is transported to the next process for drying treatment through the discharge valve and the conveying pump at the rear end.
[0062] After the discharging is completed, the material adhered to the isolation cloth bag will be straightened and shaken along with the bag pulling mechanism arranged at the upper end of the top cover. At the same time, the flushing mechanism flushes the cloth bag to achieve cleaning, thus completing a stage of stirring, washing and concentration process.
[0063] 3. Drainage system
[0064] In the mixing and stirring device of the present utility model, the conductive waste water pipe, the waste water tank, the vacuum pump, the liquid level gauge and the control valves on each connecting pipeline jointly form the drainage system of the device.
[0065] The concentrated slurry that is basically in the equilibrium state of the conductive ion concentration discharges the waste liquid containing conductive ions through the drainage system under the action of the negative pressure concentration system, and then purified water is re-injected. After repeated washing, finally qualified powder materials are obtained.
