[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-5 As shown: This utility model provides a technical solution for a gas-liquid mixing and enhancing pulp filtration device, including a body 1. A filter screen 2 is connected to the upper end of the body 1. A cover plate 3 is rotatably connected to the upper end of the filter screen 2. A mounting frame 5 is fixedly connected to the upper end of the cover plate 3. A motor 4 is fixedly connected to the upper end of the mounting frame 5. A rotating rod 6 is fixedly connected to the output end of the motor 4. The rotating rod 6 extends into the cover plate 3, and an air slip ring 7 is fixedly connected to its end. An air outlet 8 is opened at the lower end of the air slip ring 7. An air pipe is built into the air slip ring 7 and connected to an external air tank. A stirring mechanism is fixedly connected to the side wall of the rotating rod 6 inside the cover plate 3. The vibration of the body 1 causes the pulp in the filter screen 2 to vibrate, thereby separating the pulp and pulp water. Compared with traditional methods... The screening machine is designed with a mounting frame 5 fixed on the upper end of the cover plate 3. A motor 4 is fixedly connected to the upper end of the mounting frame 5. When the motor 4 is powered on, it drives the rotating rod 6 to rotate. An air slip ring 7 is fixedly connected to the lower end of the rotating rod 6. The air slip ring 7 is existing technology and will not be described in detail here. The air slip ring 7 rotates with the rotating rod 6. An air outlet 8 is opened at the lower end of the air slip ring 7. The air outlet 8 supplies air to the internal pulp through an external air tank. When rotating, air is supplied, which in turn generates air bubbles inside the pulp. When the rotating rod 6 rotates, it drives the stirring mechanism to rotate. The stirring mechanism cuts the air bubbles, and the air bubbles squeeze each other, which allows the pulp to be fully separated and squeezed, thus achieving a better pulp filtration effect.

[0023] like Figure 3 and Figure 4 As shown: The mixing mechanism includes: a mixing plate 11, which is folded and has mixing holes 12, and is fixedly connected to the side wall of the rotating rod 6; and a mixing rod 9, which is also folded and has its lower end abutting against the inner end face of the filter screen 2. When the rotating rod 6 rotates, it drives the mixing plate 11 to rotate. The mixing holes 12 can cut air bubbles and generate more air bubbles, thereby achieving a better filtration effect. Similarly, the mixing rod 9 rotates with the rotating rod 6, and its lower end abuts against the upper end face of the filter screen 2, scraping the pulp at the bottom upwards, fully enhancing the mixing of the pulp, and promoting pulp separation and filtration.

[0024] like Figure 3 and Figure 5As shown: A threaded post 13 is fixedly connected to the lower end of the cover plate 3. A partition 14 is inserted into the opposite side of the threaded post 13. Connecting blocks 15 are fixedly connected to both sides of the connecting end of the partition 14. The two connecting blocks 15 are fixedly connected by fixing screws. A fixing button 16 is threadedly connected to the threaded post 13. The threaded post 13 is fixed at the center of the lower end of the cover plate 3 and is located outside the rotating rod 6. The partition 14 is snapped to both ends of the outer side of the threaded post 13. The partition 14 is made of aluminum alloy plate, which is lightweight and has high hardness. It prevents the pulp from splashing onto the cover plate 3 when the pulp is mixed. After the two partitions 14 are aligned, they are fixed by fixing screws passing through the connecting blocks 15. Then, the fixing button 16 is rotated to make the partitions 14 abut against each other on the threaded post 13. After long-term use, the partitions 14 can be removed for cleaning at any time, which is convenient for use and maintenance without disassembling the motor 4 and the rotating rod 6.

[0025] like Figure 4 As shown: A baffle 10 is fixedly connected to the outside of the inclined end of the stirring rod 9. The baffle 10 is staggered vertically, and the end of the baffle 10 is flush with the end of the stirring rod 9. The baffle 10 can push the pulp inside forward as the stirring rod 9 rotates, and the staggered vertical arrangement of the baffle 10 can push the pulp in the filter screen 2 in the opposite direction, promoting the separation and filtration of the pulp.

[0026] like Figure 3 As shown: The stirring plate 11 is inclined and fixed to the side wall of the rotating rod 6. The inclined stirring plate 11 can increase the contact area with the pulp when rotating, and the stirring efficiency can be improved by the inclined stirring plate 11.

[0027] like Figure 5 As shown: the air outlet 8 is located at the lower end of the air slip ring 7, and there are multiple outlets. After the air slip ring 7 releases air from the lower end, it can float and push the pulp upward with the air release. The multiple air outlets 8 can effectively increase the amount of air bubbles inside.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
