Description

Technical Field

[0001] This utility model relates to the field of pulp production equipment technology, specifically a pulp filtration device. Background Technology

[0002] Pulp filtration is crucial in the paper production process. As the basic raw material for papermaking, the purity of pulp directly determines the quality of the paper. If impurities are present in the pulp, the resulting paper will have defects such as spots and holes, severely affecting its appearance and physical properties, reducing its strength, smoothness, and uniformity, and failing to meet the production requirements of high-quality paper products.

[0003] Currently, metal impurities are often mixed into pulp, which may originate from raw materials, wear and tear of production equipment, etc. For example, utility model patent with announcement number CN215164140U discloses a pulp filtration device, which drives a rotating shaft to rotate through a drive mechanism, thereby driving a crossbar and a magnet to rotate, causing metal impurities to be adsorbed onto the magnet, thus removing metal impurities from the pulp.

[0004] However, after the magnet of this utility model adsorbs metal impurities, the metal impurities on the magnet are difficult to clean, the operation is cumbersome and time-consuming, and it affects production efficiency. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a pulp filtration device. By covering multiple stirring rods with a plastic cover, when the magnetic strips on each stirring rod adsorb metal impurities, the metal impurities are adsorbed onto the outer wall of the plastic cover. During cleaning, only the plastic cover needs to be removed. This makes it convenient for personnel to clean the metal debris on the magnetic strips, shortens the cleaning time, and improves production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulp filtration device, comprising a workbench, on which a filter screen is detachably mounted; a plurality of telescopic cylinders are mounted on the upper surface of the workbench; a top plate is mounted on the top of the plurality of telescopic cylinders; a motor is mounted on the top of the top plate; the output shaft of the motor passes through the top plate and is connected to a rotating plate at its end; a plurality of stirring rods are mounted on the bottom of the rotating plate; a plurality of magnetic strips are embedded in each stirring rod; and a plastic cover is detachably mounted on the bottom of the rotating plate, which is fitted over the plurality of stirring rods.

[0007] Preferably, the workbench is provided with an annular groove and a through groove, the top outer side of the filter screen is provided with a ring body, the ring body is fixed in the annular groove by bolts, and the filter screen is disposed in the through groove.

[0008] Preferably, a flow guide is provided at the bottom of the workbench and below the filter screen.

[0009] Preferably, multiple limiting cylinders are provided through the worktable, and multiple limiting rods are provided at the bottom of the top plate, with the multiple limiting rods vertically sliding in the multiple limiting cylinders.

[0010] Preferably, an inlet pipe is provided through the top plate.

[0011] This utility model provides a pulp filtration device, which has the following beneficial effects:

[0012] 1. This utility model uses a plastic cover to cover multiple stirring rods. When the magnetic strip on each stirring rod attracts metal impurities, the metal impurities are attracted to the outer wall of the plastic cover. During cleaning, the plastic cover can be removed. This makes it convenient for personnel to clean the metal debris on the magnetic strips, shortens the cleaning time, and improves production efficiency.

[0013] 2. The flow guide hood of this utility model has a conical structure and an outlet at the bottom. After the pulp liquid is filtered by the filter screen, it flows out from the outlet at the bottom into the collection device under the guidance of the flow guide hood. When multiple telescopic cylinders drive the top plate to move vertically, the top plate drives multiple limiting rods to move vertically in multiple limiting cylinders. The limiting cylinders can limit the limiting rods, so that the multiple limiting rods always remain in a vertical state, thereby keeping the top plate in a horizontal state.

The top outer side of the filter screen 3 is provided with a ring body 2, which is fixed in the annular groove 1-1 by bolts. The filter screen 3 is provided in the through groove 1-2.

[0022] In this embodiment, when the filter screen 3 needs to be cleaned after a period of use, the telescopic ends of multiple telescopic cylinders 4 extend, causing the top plate 5 to move vertically upward. The top plate 5 drives the motor 6 to move vertically upward, the motor 6 drives the rotating plate 7 to move vertically upward, and the rotating plate 7 drives multiple stirring rods 8 and plastic cover 10 to move vertically upward.

[0030] The working principle and usage process of this utility model: When filtering pulp liquor, the telescopic ends of multiple telescopic cylinders 4 are in a retracted state (please refer to...). Figure 1 By feeding pulp into filter screen 3, the output shaft of motor 6 drives rotating plate 7 to rotate. Rotating plate 7 drives multiple stirring rods 8 and plastic cover 10 to rotate, causing multiple magnetic strips 9 on each stirring rod 8 to adsorb metal impurities in the pulp. The attraction of multiple magnetic strips 9 can adsorb metal impurities in the pulp and on filter screen 3 onto the outer wall of plastic cover 10. After the pulp is filtered, the rotation of motor 6 is stopped, and the telescopic ends of multiple telescopic cylinders 4 extend (please refer to...). Figure 2The top plate 5 moves vertically upward, which in turn moves the rotating plate 7, multiple stirring rods 8, and plastic cover 10 vertically upward. The personnel first remove the filter screen 3 for cleaning, and then remove the plastic cover 10 from the rotating plate 7. Since the metal impurities are adsorbed on the outer wall of the plastic cover 10, the metal shavings can also be cleaned when the plastic cover 10 is removed, thus saving the time of cleaning metal shavings from the magnetic strip 9. The operation is simple and improves production efficiency.
