[0030] like Figures 1-3 As shown, this specific embodiment adopts the following technical solution: It includes a conveying pipe 1, a filter press cylinder 2, and a centrifuge 3. The filter press cylinder 2 is fixedly installed at the right end of the conveying pipe 1. The centrifuge 3 is connected to the bottom of the filter press cylinder 2 through a connecting pipe.

The upper part of the protective plate 18 is fixedly connected to the filter press cylinder 2. Through the cooperation of the guide plate 17 and the protective plate 18, the solid waste residue discharged from the filter press cylinder 2 can be guided to avoid the solid waste residue from falling randomly and affecting the working environment.

[0031] It also includes:

[0032] Motor 4 is fixedly installed on the upper left side of the filter press cylinder 2. A feed cylinder 5 is fixedly installed at the upper end of the feed pipe 1. A screw conveyor shaft 6 is rotatably installed inside the feed cylinder 5 through a bearing. The output shaft of Motor 4 is connected to the screw conveyor shaft 6. A pre-crushing mechanism 7 connected to the screw conveyor shaft 6 is installed inside the feed cylinder 5.

[0033] Baffle 8 is fixedly installed at the right end of filter cylinder 2. Filter cylinder 2 is provided with a spiral extrusion rod 9. The two ends of the spiral extrusion rod 9 pass through filter cylinder 2 and are rotatably connected to the feed pipe 1 and baffle 8 respectively through bearings.

[0034] Fixed cylinder 10, there are two fixed cylinders 10, which are respectively fixedly installed on the left and right sides inside the filter cylinder 2. The filter screen cylinder 11 is movably sleeved on the spiral extrusion rod 9. The edge of the spiral blade of the spiral extrusion rod 9 is fixedly provided with a first brush strip 12 that movably abuts against the inner wall of the filter screen cylinder 11.

[0035] Two brush strips 13 are fixedly installed on the front and rear sides of the inner wall of the filter cylinder 2, respectively. The brush strips 13 are movable and abut against the outer ring wall of the filter screen cylinder 11. The filter cylinder 2 is provided with a synchronous drive mechanism 14 connected to the filter screen cylinder 11 and the spiral extrusion rod 9. The filter plate 15 is provided in the connecting pipe and is inclined. After the filter screen cylinder 11 and the spiral extrusion rod 9 are used for filtration, the filter plate 15 can perform secondary filtration on the liquid transported in the connecting pipe to prevent solid residue from entering the centrifuge 3. A sealing plate 16 is provided at the side wall opening of the connecting pipe through a hinge. The sealing plate 16 is located above the filter plate 15. The sealing plate 16 can be flipped to open the connecting pipe to facilitate the disassembly and cleaning of the filter plate 15.

[0036] The pre-crushing mechanism 7 includes:

[0037] A partition 7-1 is fixedly installed inside the conveying cylinder 5. A rotating cylinder 7-2 is rotatably installed inside the partition 7-1 via a bearing. The rotating cylinder 7-2 is rotatably mounted on the screw conveying shaft 6 via a bearing. A first gear 7-3 is fixedly mounted on the screw conveying shaft 6 at the right side of the rotating cylinder 7-2. A crushing cutter head 7-10 is fixedly mounted on the left end of the rotating cylinder 7-2.

[0038] Linkage shaft 7-4, there are two linkage shafts 7-4, which are respectively rotatably mounted on the right inner wall of the conveying cylinder 5 and the right side wall of the partition 7-1 via bearings. A first bevel gear 7-5 is fixedly sleeved on the linkage shaft 7-4. A fixing rod 7-6 is fixedly mounted on the top inner wall of the conveying cylinder 5. A second bevel gear 7-7 that meshes with the two first bevel gears 7-5 is rotatably sleeved on the fixing rod 7-6 via bearings.

[0039] Gear 7-8 (number two) is fixedly mounted on the right-side linkage shaft 7-4 and meshes with gear 7-3 (number one). Gear 7-9 (number three) is fixedly mounted on both the rotating cylinder 7-2 and the left-side linkage shaft 7-4, meshing with each other. Gear 7-3 (number one) has more teeth than gear 7-9 (number three), and gear 7-9 (number three) has more teeth than gear 7-8. This ensures that when gear 7-3 drives gear 7-8 to rotate, gear 7-9... Wheel 7-8 will have a higher rotational speed than gear 7-3. By utilizing the transmission cooperation of gear 7-3, gear 7-8, gear 7-9, bevel gear 7-5 and bevel gear 7-7, the screw conveyor shaft 6 can synchronously achieve the reverse high-speed rotation of the crushing cutter head 7-10 during rotation. This is to facilitate the crushing pretreatment of the material before it enters the filter cylinder 2, and to prevent long fiber clumps in the material from directly entering the filter cylinder 2 and increasing the risk of clogging of the filter screen cylinder 11.

[0040] The synchronous drive mechanism 14 includes:

[0041] Gear ring 14-1 is fixedly sleeved on filter screen cylinder 11. A second motor 14-2 is fixedly installed on the upper part of filter cylinder 2. A fourth gear 14-3 is fixedly installed on the output shaft of the second motor 14-2. The fourth gear 14-3 meshes with gear ring 14-1.

[0042] Two sprockets 14-4 are fixedly mounted on the right end of the output shaft of the second motor 14-2 and the right end of the spiral extrusion rod 9, respectively. The two sprockets 14-4 are connected by chain drive. The synchronous drive mechanism 14 can realize the synchronous reverse rotation of the filter cylinder 11 during the rotation of the spiral extrusion rod 9. This not only improves the cleaning effect of the first brush strip 12 on the inside of the filter cylinder 11, but also enables the second brush strip 13 to clean the outside of the filter cylinder 11, thus significantly reducing the risk of filter hole clogging in the filter cylinder 11.

[0043] When using this invention, the material is fed into the conveying cylinder 5, and the first motor 4 is started. The first motor 4 drives the screw conveyor shaft 6 to rotate, causing the screw conveyor shaft 6 to move the material in the conveying cylinder 5 to the right. During this process, the screw conveyor shaft 6 drives the first gear 7-3 to rotate. The first gear 7-3, through meshing with the second gear 7-8, drives the right-side linkage shaft 7-4 to rotate at high speed. By utilizing the meshing of the first bevel gear 7-5 and the second bevel gear 7-7, the synchronous reverse rotation of the two linkage shafts 7-4 can be achieved. At this time, through the meshing of the two third gears 7-9, the rotating cylinder 7-2 and the crushing head 7-10 can be driven to rotate at high speed. The screw conveyor shaft 6 and the crushing head 7-10 rotate in opposite directions, so that the crushing head 7-10 can provide pre-crushing for the material before it enters the filter cylinder 2. Subsequently, the material will enter the filter screen cylinder 11 through the conveying pipe 1. Start motor 14-2. By using the transmission of sprocket 14-4 and chain, the spiral extrusion rod 9 can be rotated. The spiral extrusion rod 9 drives the material in the filter cylinder 11 to move to the right and achieve filtration. During this process, the first brush strip 12 can rotate with the spiral extrusion rod 9 to clean the inside of the filter cylinder 11. By using the meshing of gear 14-3 and gear ring 14-1, the filter cylinder 11 can be driven to rotate, realizing the synchronous reverse rotation of the filter cylinder 11 and the spiral extrusion rod 9. As the filter cylinder 11 rotates, the second brush strip 13 in the fixed state can clean the outside of the filter cylinder 11. Through the synchronous cleaning of the inside and outside of the filter cylinder 11 by the first brush strip 12 and the second brush strip 13, the clogging of the filter holes in the filter cylinder 11 can be avoided. The filtered liquid will enter the centrifuge 3 through the connecting pipe for separation. Then the solid waste will be discharged from the right end of the filter cylinder 2.

[0044] Compared with the prior art, the beneficial effects of this utility model are:

[0045] The synchronous drive mechanism 14 enables the filter cylinder 11 and the spiral extrusion rod 9 to rotate synchronously in opposite directions. With the help of the first brush strip 12 and the second brush strip 13, the inner and outer walls of the filter cylinder 11 can be cleaned synchronously, realizing dynamic self-cleaning during the filter pressing process. This effectively prevents paulownia fiber and gum components from clogging the filter holes, significantly improves the filtration efficiency, and avoids the problem of production interruption required by traditional backwashing technology, ensuring continuous operation.

[0046] With the cooperation of the pre-crushing mechanism 7, the long fiber clumps can be fully crushed and pre-treated before the material enters the filter press cylinder 2, which greatly reduces the risk of clogging of the subsequent filter screen cylinder 11, and at the same time improves the uniformity and thoroughness of solid-liquid separation.

[0047] After pressure filtration is achieved using the filter cylinder 11 and the screw extrusion rod 9, the filter plate 15 can effectively intercept residual solid particles, preventing them from entering the centrifuge 3 and ensuring the purity and separation accuracy of the final product.

[0048] The combination of the guide plate 17 and the protective plate 18 can provide discharge guidance for the solid waste residue discharged from the filter press cylinder 2, preventing the solid waste residue from scattering randomly and affecting the working environment.

[0049] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
