Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The special high-speed dispersion device for wood lacquer production shown in fig. 1 comprises a cylinder body 1, wherein a dispersion cavity 2 is formed inside the cylinder body, a stainless steel filter screen 3 is arranged in the dispersion cavity, a backflow cavity 4 is formed inside the filter screen, a rotating roller 5 is arranged inside the backflow cavity, a plurality of jet holes 6 are formed in the surface of the rotating roller; the upper end of the roller is provided with a feeding pipe 7 communicated with the inside of the roller.

During the dispersion treatment, the paint is injected into the roll through a feed pipe.

The feed pipe extends upwards through the filter screen and the cylinder wall, and a bearing 8 is arranged between the feed pipe and the filter screen; the upper end of the feeding pipe is connected with a feeding hole 10 through a rotary joint 9.

The pipe body of the feeding pipe is fixedly connected with a driving gear 11, the driving gear is meshed with a transmission gear 12, and the transmission gear is fixedly connected with an output shaft of a motor 13.

Under the transmission action of the transmission gear and the driving gear, the torque of the motor is transmitted to the feeding pipe, so that the feeding pipe rotates at a high speed. The feed pipe is fixedly connected with the rotary roller, so that the rotary roller rotates at a high speed. The roller rotating at high speed generates centrifugal force to paint inside, so that the paint is sprayed into the return cavity from the spray hole under the action of the centrifugal force and is hit on the filter screen.

Such beating action breaks up large droplets or agglomerates in the paint, allowing them to disperse. After the small liquid drops which can pass through the filter screen are dispersed, the small liquid drops can pass through the filter screen into the dispersion cavity and flow down from the inner wall of the cylinder. A discharge pipe 14 communicated with the outside of the barrel body is arranged at the bottom of the dispersion cavity and is only communicated with the dispersion cavity; the small liquid drops after being hit can leave the cylinder body from the discharge pipe.

Paint that is not broken up cannot pass through the screen into the dispersion chamber and is trapped in the recirculation chamber. The bottom of the reflux cavity is provided with a reflux port 15, the wall of the barrel body positioned at the bottom end of the barrel body is provided with a reflux pipe 16, one end of the reflux pipe is communicated with the reflux port, and the other end of the reflux pipe extends to the upper end of the barrel body and is communicated with the feed inlet through a tee joint; the return port is only communicated with the return cavity. The paint flows through the return opening into a return pipe, on which a pump 20 is mounted, under the action of which the paint re-enters the feed pipe and undergoes the breaking process again until it passes through the screen.

The rotating roller is in a long cylindrical shape, and can be beneficial to generating centrifugal force by high-speed rotation of the rotating roller. The lower end of the roller is connected to a post 18 via a turntable 17, the roller rotating relative to the post. The pillar can play the effect of support and restriction to the change roller, guarantees to change the roller and can not rock lower end when high-speed rotating, and is more stable.

The support is positioned in the backflow port, and the diameter of the support is smaller than the caliber of the backflow port. So that the prop does not block the backflow port.

The rotary joint is arranged in the cylinder wall, and the rotary joint enables the rotary feed pipe not to be limited by the cylinder wall.

The return pipe is communicated with the return port through a communicating pipe 19, the communicating pipe and the return port are equal in diameter, the communicating pipe vertically extends, and the return cavity is isolated from the dispersion cavity. The communicating pipe is used for isolating the backflow cavity and the dispersion cavity, so that liquid drops scattered by the filter screen cannot be mixed with liquid drops which are not scattered.

The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
