[0002] With the continuous development of papermaking industry, the use and popularity of high-concentration slag removal equipment has reached a very high level. High-concentration slag remover uses the different centrifugal force principles of different media under the same acceleration to quickly separate heavy impurities, thereby improving the cleanliness of the required pulp and reducing the wear on subsequent equipment.

[0003] The centrifugal force generated by the high-speed rotation of the high-concentration slag remover during operation concentrates the heavy impurities contained in the raw materials on the inner wall of the slag removal cone. During the long-term slag removal process, the heavy impurities are easy to adhere to the inner wall of the slag removal cone. Failure to clean them in time will not only affect the discharge effect of the heavy impurities sliding downward, but also cause serious adhesion of impurities on the inner wall of the slag removal cone, thereby destroying the slag removal effect of the slag removal cone.

To this end, the utility model proposes an improved high-concentration slag removal system, which solves the problem that heavy impurities are easily adhered to the inner wall of the slag removal cone of the existing high-concentration slag remover, thereby affecting the slag removal effect.

In this embodiment, the specific number of the high-concentration slag removers 2 is four. The bottom of the annular shell 1 is connected to a slag collecting shell 15 with a conical structure, which is convenient for collecting the separated slag. The bottom of the slag collecting shell 15 is installed with a plurality of supporting legs 16, and the bottom end of the slag collecting shell 15 is installed with a slag discharge port, which is convenient for slag discharge. The high-concentration slag remover 2 includes a cylinder 201 and a slag removal cone 202.

[0021] An upper ring body 5 with a hollow structure is provided above the high-concentration cleaner 2, and a plurality of cylinders 201 are connected to a lower ring body 8 with a hollow structure through a bracket. A slurry guide pipe 9 is connected between the lower ring body 8 and the cylinder 201, and the slurry guide pipe 9 is tangent to the inner wall of the cylinder 201, so that the slurry enters the high-concentration cleaner 2 along the tangent line and forms a vortex, thereby utilizing the rotating centrifugal force to separate the slurry in the high-concentration cleaner 2. One end of the lower ring body 8 is connected to a slurry inlet pipe 10, a good slurry pipe 6 is connected between the bottom of the upper ring body 5 and the top of the high-concentration cleaner 2, and a slurry discharge pipe 7 is connected to one side of the upper ring body 5.

[0022] A rotating tube 3 is rotatably installed at the bottom of the slag removal cone 202, which is convenient for discharging heavy impurities sliding along the inner wall of the slag removal cone 202 through the rotating tube 3. The rotating tube 3 is rotatably connected to the bottom of the slag removal cone 202 through a sealed bearing to ensure the sealing of the rotating connection. A scraper 4 that fits the inner wall of the slag removal cone 202 is installed on the edge of the top of the rotating tube 3, which is convenient for driving the scraper 4 to clean the heavy impurities adhered to the inner wall of the slag removal cone 202 when the rotating tube 3 rotates. A through hole for the rotating tube 3 to pass through is opened on the top of the annular shell 1, and a driving mechanism for driving the rotating tube 3 to rotate is installed in the annular shell 1.

[0023] The driving mechanism includes a gear 11 fixedly mounted on the outer tube wall of the rotating tube 3, an outer gear ring 12 meshing with the gear 11 is provided at the center of the annular housing 1, a horizontal column 13 having the same diameter as the gear ring 12 is installed inside the outer gear ring 12, and a motor 14 connected to the horizontal column 13 is installed on the top of the annular housing 1, so that the motor 14 can be started to drive the horizontal column 13 and the outer gear ring 12 to rotate, thereby making the multiple rotating tubes 3 equipped with the gears 11 rotate synchronously;

[0024] In this embodiment, the rotation direction of the rotating tube 3 is consistent with the centrifugal rotation direction of the slurry in the high-concentration cleaner 2. A partition 17 is provided below the cross column 13. The partition 17 is installed in the annular shell 1. A bearing seat is installed at the center of the upper surface of the partition 17, and a rotating pin connected to the cross column 13 is rotatably installed on the bearing seat to facilitate supporting the cross column 13 and improve the rotation stability of the outer gear ring 12. A rotating hole corresponding to the rotating tube 3 is opened through the partition 17. The rotating tube 3 is arranged through the rotating hole, and a sealing ring is installed between the rotating tube 3 and the rotating hole to ensure sealing.

[0025] The working principle of the utility model is as follows: the high-concentration slurry to be deslagging is introduced into the lower ring body 8 through the slurry inlet pipe 10, and the slurry enters the high-concentration deslagging device 2 along the tangent through multiple slurry guide pipes 9 and forms a vortex shape, so that the slurry is separated in the high-concentration deslagging device 2 by the rotating centrifugal force, so that the good slurry containing light fibers rises along the cylinder 201, and then flows into the upper ring body 5 through the good slurry pipe 6, and is finally discharged from the slurry discharge pipe 7, while the heavy impurities are concentrated in the deslagging cone 202 and slide downward along its inner wall, and are finally discharged through the rotating pipe 3. The starting motor 14 drives the cross column 13 and the outer gear ring 12 to rotate, so that the multiple rotating pipes 3 equipped with gears 11 can rotate synchronously, and the rotating pipe 3 drives the scraper 4 to clean the heavy impurities adhering to the inner wall of the deslagging cone 202, and finally the heavy impurities are discharged into the slag collecting shell 15 through the rotating pipe 3, and the slag discharge port is opened regularly to discharge the slag.

[0026] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
