[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 The anti-precipitation nano-suspension grinding device in this embodiment includes a grinding tank 1, a feeding hopper 2 fixedly connected to the top of the grinding tank 1, a locking block 3 fixedly connected to the outside of the grinding tank 1, a movable filter plate 301 disposed inside the locking block 3, a first motor 8 fixedly connected to the bottom wall of the grinding tank 1, a stirring paddle 9 fixedly connected to the output shaft of the first motor 8, a support block 6 fixedly connected to the inside of the grinding tank 1, an isolation plate 10 fixedly connected to the inside of the grinding tank 1, and a filter structure 11 disposed inside the grinding tank 1.

[0021] The filter structure 11 includes a second motor 1101, which is fixedly connected to the top of the support block 6. The output shaft of the second motor 1101 is fixedly connected to a cam 1102. The cam 1102 is hinged to a connecting rod 1103. An impact block 1105 is hinged to the top of the connecting rod 1103. A support rod 1104 is fixedly connected inside the grinding tank 1. A vibrating filter plate 1107 is hinged to the support rod 1104. A limit block 1106 is fixedly connected to the bottom of the vibrating filter plate 1107.

[0022] The limiting block 1106 has a limiting groove inside, and the impact block 1105 is snapped into the limiting groove. The limiting groove and the impact block 1105 are adapted to each other. The limiting groove of the limiting block 1106 and the impact block 1105 are adapted to snapped into each other, which can limit the movement trajectory of the impact block 1105 and ensure that the impact block 1105 can accurately act on the limiting block 1106 when it moves with the connecting rod 1103, thereby stably driving the vibrating filter plate 1107 to vibrate, avoiding the impact block 1105 from deviating and causing the filter structure 11 to operate unstablely, thus ensuring the filtration effect.

[0023] The output shaft of the first motor 8 passes through the isolation plate 10 and is fixedly connected to the stirring paddle 9. A shaft seal 801 is provided at the connection between the first motor 8 and the isolation plate 10. The shaft seal 801 is fixedly connected to the isolation plate 10. The output shaft of the first motor 8 passes through the isolation plate 10 and connects to the stirring paddle 9 to achieve the stirring and anti-sedimentation function. The shaft seal 801 is fixed to the isolation plate 10 and can seal the connection between the motor output shaft and the isolation plate 10 to prevent the nano-suspended agent in the grinding tank 1 from leaking from the gap. At the same time, it does not affect the normal rotation of the output shaft, ensuring the dual effect of stirring and sealing.

[0024] A valve 7 is fixedly connected inside the grinding tank 1. The valve 7 is located on the right side of the movable filter plate 301. A square hole is opened inside the locking block 3, which is adapted to the movable filter plate 301. A magnet 302 is fixedly connected inside the locking block 3. The magnet 302 is located below the movable filter plate 301 and is magnetically connected to the movable filter plate 301. The valve 7 is located on the right side of the movable filter plate 301 and can control the material flow on the right side of the movable filter plate 301. The square hole of the locking block 3 is adapted to the movable filter plate 301, which facilitates the quick installation and removal of the movable filter plate 301. The magnet 302 magnetically fixes the movable filter plate 301 to prevent it from loosening during operation, and at the same time facilitates the removal and cleaning of impurities on the filter plate, improving maintenance convenience.

[0025] A coolant inlet pipe 5 is fixedly connected to the right side of the outside of the grinding tank 1, and a cooling pipe 101 is fixedly connected inside the grinding tank 1. The cooling pipe 101 is connected to the coolant inlet pipe 5, and the coolant inlet pipe 5 supplies coolant to the cooling pipe 101. The cooling pipe 101 is distributed inside the grinding tank 1 and can absorb the heat generated during the grinding process to cool down the nano-suspension in the tank, so as to avoid the temperature from being too high and affecting the stability and performance of the suspension.

[0026] The bottom of the grinding jar 1 is fixedly connected with four self-locking casters 4, which are evenly distributed on the bottom of the grinding jar 1. The four evenly distributed self-locking casters 4 can flexibly move the grinding jar 1 to adapt to different working position requirements; its self-locking function can fix the position when the device is working, prevent slippage, and take into account both the flexibility of movement and the stability of operation.

[0027] During implementation, several silicon carbide beads are placed inside the grinding tank 1. Through high-frequency collision and shearing between the silicon carbide beads and the solid particles in the raw material, the raw material particles are broken from the micron level to the nano level.

[0028] In practice, the movable filter plate 301 is used to block silicon carbide beads.

[0029] During implementation, the coolant inlet pipe 5 is connected to an external coolant source, and coolant is supplied to the inside of the coolant inlet pipe 5.

[0030] When implementing this procedure, please follow these steps:

[0031] 1) First, pour the raw material to be ground, such as a mixture of solid particles and liquid medium, into the grinding tank 1 through the feed hopper 2. Start the second motor 1101 to drive the cam 1102 to rotate. Through the connecting rod 1103, the impact block 1105 repeatedly impacts the limiting block 1106, forcing the vibrating filter plate 1107 to vibrate and intercept large particle impurities.

[0032] 2) Then connect the coolant inlet pipe 5 to the external coolant source so that the coolant flows into the cooling pipe 101 to cool the grinding tank 1 in advance;

[0033] 3) Restart the first motor 8 to drive the stirring paddle 9 to rotate. Through the shear force and turbulence of the stirring paddle 9, the particles are initially dispersed and sedimentation is prevented.

[0034] 4) After the final grinding is completed, first turn off the first motor 8 and the second motor 1101 to stop stirring and filtering, and then open the valve 7 to collect the finished nano suspension in the container.

[0035] In summary, this anti-sedimentation nano-suspension grinding device uses a second motor 1101 in the filter structure 11 to drive a cam 1102 and a connecting rod 1103, causing the impact block 1105 to repeatedly strike the limiting block 1106, forcing the vibrating filter plate 1107 to vibrate at high frequency, thus filtering large particles in the raw material and preventing filter pore blockage. A first motor 8 drives the stirring paddle 9 to rotate continuously, generating strong shear force and turbulence, breaking the agglomeration tendency of nanoparticles and preventing particles from settling due to gravity. A coolant inlet pipe 5 delivers coolant to the cooling pipe 101 inside the grinding tank 1. The cooling pipe 101 adheres to the tank wall and quickly absorbs the heat generated during grinding and stirring, preventing the problem of nanoparticle agglomeration and decreased suspension stability caused by temperature rise.
