Description

TECHNICAL FIELD

[0001] The utility model discloses secondary battery production utensil technical field, specifically point to a kind of double planetary stirring container of convenient cleaning residual material. BACKGROUND

[0002] Currently, double planetary mixers are generally used in polymer battery slurrying. The double planetary mixer is a kind of high-efficiency mixing equipment, which is mainly used for stirring high-viscosity and high-density slurry.

[0003] The working principle of the double planetary mixer is that the stirring paddle performs a combination of revolution and self-rotation. When stirring the slurry, the low-speed stirring part adopts planetary gear transmission, and the stirring paddle rotates while revolving, so that the material moves up and down and around, thereby achieving an ideal mixing effect in a short time. The high-speed dispersion part revolves with the planetary carrier and rotates at high speed, producing strong shearing and dispersion mixing effect, so that the particles are quickly dispersed and uniformly dispersed.

[0004] The outstanding advantage of the double planetary mixer is that it can conveniently adjust process parameters such as feeding sequence, rotation speed and time to adapt to different material properties, and can easily rework when the slurry properties do not meet the requirements, so it has strong adaptability and flexibility.

[0005] However, when cleaning the residual material, due to the complex structure of the transmission shaft and the sharp sawtooth of the dispersing disc, it is difficult to clean all around before feeding after changing the formula, which increases the cleaning time and reduces the production efficiency, and the sharp sawtooth of the dispersing disc increases the risk of manual scratching.

[0006] Specifically, during the cleaning process of the double planetary mixer, especially the cleaning of the positive electrode mixer, it is difficult to clean comprehensively due to many factors. For example: 1. The NMP solvent in the positive electrode oil-based slurry is corrosive, and the body needs to avoid contact with the corrosive solvent during comprehensive cleaning, increasing the risk of injury. 2. PVDF in the positive electrode oil-based slurry has the characteristics of large molecular weight and strong adhesion, and after mixing with the positive electrode main material, it is difficult to clean comprehensively on the transmission shaft and the dispersing disc. 3. The sawtooth of the dispersing disc is uneven, which is the key area of slurry cleaning. If not cleaned thoroughly, there is a risk of mixing during the next batch of uniform slurry, and the hard and sharp sawtooth of the dispersing disc increases the risk of manual scratching during thorough cleaning. Invention content

[0007] The utility model aims at providing a double planetary stirring container for conveniently cleaning residual material, which has the characteristics of high cleaning efficiency, low safety risk and convenient operation.

[0008] The utility model can be realized by the following technical solutions:

[0009] The utility model discloses a convenient to clean residual material's double planetary stirring container for the movable insertion stirring head, and the stirring container is the barrel structure, including the cylindrical container wall portion and the container closed bottom portion that closes liquid in the container wall bottom, the container wall portion and container closed bottom portion are all the inner empty interlayer structure, the interlayer structure of container wall portion evenly has a plurality of first ultrasonic vibration elements, and the container closed bottom portion is built -in oscillator, and the oscillator is electrically connected with first ultrasonic vibration element and produces high -frequency resonance to ultrasonic cleaning to the container inner wall when cleaning.

[0010] In the utility model information, the ultrasonic cleaning mode is the mode that utilizes ultrasonic vibration to clean the surface of object, and the utility model mainly comprises following two core parts:

[0011] Vibration element (transducer): the vibration element is piezoelectric transducer or magnetostrictive transducer, and it can convert electrical signal into mechanical vibration. These vibrations are transmitted in the form of ultrasonic waves into the cleaning liquid, generating tiny bubbles, which rapidly grow and collapse near the surface of the object, generating shock waves that help remove dirt and other impurities from the surface of the object.

[0012] Oscillator (generator): the oscillator is an electronic device used to generate high-frequency electrical signals. This high-frequency signal is transmitted to the vibration element through a cable, driving it to produce ultrasonic waves. The oscillator can adjust the frequency and power of the output signal to adapt to different cleaning needs and material types.

[0013] The working principle of ultrasonic cleaning is that the ultrasonic waves generated by the vibration element propagate in the liquid, forming acoustic pressure waves. These acoustic pressure waves form tiny bubbles (cavitation phenomenon) in the liquid, which rapidly grow and suddenly collapse under the action of the acoustic waves. The collapse of the bubbles produces extremely high local pressure and temperature, effectively removing dirt and grease adhering to the surface of the object.

[0014] Further, the container closed bottom portion further comprises a second ultrasonic vibration element, and the oscillator is electrically connected with the second ultrasonic vibration element to produce high-frequency resonance for ultrasonic cleaning of the inner wall of the container during cleaning.

[0015] Further, the vibration frequency of the first ultrasonic vibration element and the second ultrasonic vibration element during cleaning is the same.

[0016] Further, the oscillator is electrically connected with the commercial power supply through a power cord.

[0017] Further, the oscillator is a single-frequency oscillator, a multi-frequency oscillator and a continuously adjustable oscillator. Different types can meet different needs, such as a single-frequency oscillator that can only work at a fixed frequency; a multi-frequency oscillator that can switch between several preset frequencies, increasing the flexibility and applicability of the device; and a continuously adjustable frequency oscillator that can continuously adjust within a wide frequency range, suitable for experiments and fine adjustments in special cases.

[0018] Further, the frequency range of the oscillator is 28-40 kHz and / or 68-130 kHz. Taking 28-40 kHz as an example, it is the most common frequency range, suitable for most cleaning tasks, and can better balance cleaning efficiency and item protection; taking 68-130 kHz as an example, a high-frequency oscillator suitable for cleaning very small particles.

[0019] Further, the first ultrasonic vibration element column is uniformly distributed along the circumference, and the second ultrasonic vibration element is uniformly distributed in a concentric ring shape.

[0020] Further, the inner wall and the outer wall of the stirring container are metal walls, and the inner wall and the outer wall are a detachable structure.

[0021] Further, the columnar first ultrasonic vibration element is attached to the back of the inner wall of the container wall.

[0022] The utility model discloses a double planetary stirring container convenient for cleaning residual materials, which has the following beneficial effects:

[0023] First, the cleaning efficiency is high. When the ultrasonic wave acts on the liquid, the breaking of each bubble in the liquid produces a shock wave with great energy. The shock wave produced by the breaking of the bubbles in the liquid can quickly and efficiently clean and flush the residual materials on the inner and outer surfaces of the kettle.

[0024] Second, the safety risk is low. When the staff prepares the next batch of materials, they need to clean the inside of the kettle body of the current batch of slurry. The slurry adhered to the dispersion disc is much and the disc body is sharp and sharp, and the staff is easy to be scratched when cleaning. The container of the utility model can clean the dispersion disc by ultrasonic wave, effectively avoiding the risk of scratching during cleaning.

[0025] Third, the operation is convenient. When cleaning is needed, the power of the oscillator is turned on to drive the vibration element to start the high-frequency cleaning process after the safety inspection work is ready, effectively simplifying the cleaning operation process.
