Description

Technical Field

[0001] This utility model relates to the field of pulp residue treatment technology. Specifically, it relates to a pulp residue filtration device. Background Technology

[0002] Pulp is a fibrous material made from plant fibers through different processing methods. It can be classified according to the processing method into mechanical pulp, chemical pulp, and chemimechanical pulp. It can also be classified according to the fiber raw materials used into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. Furthermore, it can be classified according to different purity into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc.

[0003] Filtering impurities from the pulp can easily clog the filter screen, making it impossible to clean the surface of the filter screen in a timely manner and collect the residue. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a pulp residue filtration device. The lifting frame can be raised and lowered to squeeze the water inside the residue upward, while the filter screen can rotate downward. The rotation of the filter screen can contact one end of the translation plate, so that the translation plate scrapes off the residue above the filter screen.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] The device includes a housing, with a lifting mechanism at the bottom. The lifting mechanism includes a lifting frame and a lifting rod. The lifting rod is located inside the housing, and the lifting frame is mounted on the upper surface of the lifting rod. A filter screen is rotatably mounted above the lifting frame, and a water receiving tray is mounted below the filter screen. A sealing mechanism is located inside the housing, including a sliding plate and a supply plate. The sliding plate is slidably mounted on one side of the housing, and the supply plate is slidably mounted in the middle of the housing. A pressing mechanism is located on one side of the sliding plate, including a rotating plate, a pressing plate, and a accumulating plate. The pressing plate is slidably mounted on one side of the sliding plate.

[0007] The technical solution of this utility model has achieved the following beneficial technical effects:

[0008] The lifting frame's adjustable height allows for upward squeezing of moisture from the residue, while simultaneously rotating the filter screen downwards. This rotation brings the filter screen into contact with one end of a sliding plate, which then scrapes off the residue from the top of the filter screen. The lifting frame's upward movement also rotates the discharge cover, facilitating the collection of residue at the bottom. The movable sliding plate allows the lower pressure plate to release downwards, contacting the filter screen surface and quickly removing residue accumulated at the edges of the filter screen.

[0014] This implementation example is attached to the instruction manual. Figure 1-4 As shown, the cross-section of the housing 1 is a square. A lifting frame 2 is installed at the bottom of the housing 1, and the bottom of the lifting frame 2 is inserted into the water outlet pipe. Lifting rods 3 are installed on both sides of the lifting frame 2. The lifting rods 3 are a type of electric push rod, which allows the lifting frame 2 to move upwards. A water inlet pipe 22 is installed above the housing 1. A supply plate 7 is slidably installed on the lower surface of the water inlet pipe 22. A supply channel 20 is opened inside the supply plate 7. A supply valve 21 is rotatably installed at the bottom of the supply channel 20. The supply valve 21 is circular in shape (one end of the supply valve 21 requires a motor to control the rotation angle), and its lower part is cut into a flat surface, as shown in the attached instruction manual. Figure 1 At this time, the inlet pipe 22 is connected to the supply channel 20, and the supply valve 21 blocks the supply channel 20. As the supply valve 21 rotates 90 degrees, the pulp waste reaches the filter screen 4. The filter screen 4 has uniform small holes, so the liquid can reach the water receiving tray 5. The liquid in the water receiving tray 5 automatically flows to the lifting frame 2, and finally reaches the outlet pipe. At this time, as per the instruction manual... Figure 1As shown, the lifting rod 3 drives the lifting frame 2 to move upward, thus squeezing the residue above and compacting it while squeezing out the liquid. The liquid is transported along the water receiving tray 5 and the lifting plate. A sliding plate 6 is slidably installed above the box 1, with springs supporting its edges. The supply plate 7 is also supported by springs. The supply plate 7 and the sliding plate 6 form a complete plane. As the lifting frame 2 contacts the bottom of the supply plate 7 and continues to move upward, the filter screen 4 will rotate. A torsion spring is installed on the edge of the rotation center of the filter screen 4. Under the action of the torsion spring, the filter screen 4 rotates. As the filter screen 4 becomes horizontal, the lifting frame 2 moves upward. The narrower top of the lifting frame 2 can press against the bottom of the supply plate 7, forcing the filter screen 4 to rotate. This causes the sharp end of the translation plate 6 to slide along the surface of the filter screen 4. As the lifting frame 2 continues to move upward, the residue on the surface of the filter screen 4 is pushed along both sides. Since the rotation angle of the filter screen 4 on the lifting frame 2 is limited, as the lifting frame 2 continues to rise, the translation plate 6 has to move laterally to both sides, causing one sharp side of the translation plate 6 to scrape off the residue on the filter screen 4.

[0015] As per the instruction manual Figure 2 As shown, to facilitate the falling of residue, this design includes a slidable striking rod 14 on the side of the lifting frame 2. A striking spring 15 is installed between the striking rod 14 and the lifting frame 2. As the lifting frame 2 moves upward, a horizontal block 16 is rotatably installed at the bottom of the housing 1. A side spring 17 is installed on the side of the center of rotation of the horizontal block 16. The side spring 17 is a torsion spring with a large elastic force. Therefore, as the lifting frame 2 moves upward, the striking rod 14 is positioned under the horizontal block 16, causing the striking rod 14 to remain stationary and continuously stretch the striking spring 15. The distance the striking rod 14 slides on the lifting frame 2... Due to the limited distance, the final striking rod 14 has to move upwards, causing the horizontal block 16 to rotate and release the striking rod 14. Because the striking spring 15 is compressed at this moment, the striking rod 14 moves rapidly upwards upon release, striking the water tray 5, making it easier for the residue scraped off the filter screen 4 to fall off. As the lifting frame 2 resets downwards, it compresses the horizontal block 16, causing it to rotate downwards (because the horizontal block 16 is located at the bottom of the housing 1, it has no sliding space; as the striking rod 14 moves downwards, it compresses the horizontal block 16, causing it to rotate downwards; as the horizontal block 16 rotates and resets, as shown in the instruction manual). Figure 3 (As shown).

[0016] To allow the residue to fall off automatically, a discharge cover 18 is rotatably mounted on the top of the housing 1. A torsion spring is also installed on the edge of the discharge cover 18. Under normal circumstances, the discharge cover 18 is horizontal. An inclined bar 19 is integrally installed on the edge of the discharge cover 18, while a circular block is integrally installed at the bottom of the lifting frame 2. As the circular block moves upward, it controls the offset of the inclined bar 19, causing the discharge cover 18 to rotate downward. Correspondingly, the bottom of the housing 1 opens, allowing a conveyor belt for collecting filter residue to be installed on the lower side of the housing 1, enabling complete collection of the filter residue. (See attached instruction manual) Figure 4 As shown, because residue easily accumulates on the edges of the filter screen 4, the translation plate 6 moves to both sides during the process described above. During this movement, the storage spring 11 is activated. The storage spring 11 is positioned between the lower pressure plate 9 and the storage plate 10. The storage spring 11 has a relatively large elastic force. Cylindrical posts are located on both sides of the storage plate 10 (on the inner side of the housing 1). A first strip 12 and a second strip 13 are also located at these posts. The first strip 12 and the second strip 13 are fixed to the inner side wall of the housing 1, as shown in the instruction manual. Figure 4 As described above, there is a cylinder on one side of the energy storage plate 10, and also a cylinder on the edge of the lower pressure plate 9. As the translation plate 6 of this scheme moves to the left, it will also drive the lower pressure plate 9 to move to the left. At this time, because the energy storage plate 10 and the lower pressure plate 9 have cylinders on their edges, and the first strip 12 is an oblique strip, the energy storage plate 10 will move downward. However, because the cylinder of the lower pressure plate 9 overlaps with the horizontal second strip 13, the lower pressure plate 9 cannot move downward. Therefore, the storage spring 11 is compressed. Since the second strip 13 is slightly shorter, moving it to the left side of the second strip 13 will release the lower pressure plate 9. Under the action of the storage spring 11, the lower pressure plate 9 moves rapidly downward, squeezing and removing the residue from the edge of the filter screen 4. To facilitate fitting against the edge of the filter screen 4, a rotating plate 8 is rotatably provided below the lower pressure plate 9. The rotating plate 8 can fit against the edge of the filter screen 4 for squeezing. As the translation plate 6 returns to its original position, the lower pressure plate 9 and the storage plate 10 will move as shown in the instruction manual. Figure 4 The lower pressure plate 9 is reset because it also has a spring at its edge. This spring has a smaller elastic force than the storage spring 11. The function of this spring is to enable the lower pressure plate 9 to reset.
