[0003] Traditional slag removal methods, such as manual screening and sedimentation tank settling, suffer from problems such as low efficiency, high labor intensity, large footprint, and easy clogging, making it difficult to meet the needs of large-scale, continuous production. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] (1) By setting up a modification tank, a modification mechanism and a slag discharge mechanism, when in use, the short fibers are first sent into the modification tank, water and modifier are injected into the modification tank, and then the short fibers are modified by the modification mechanism. Then the solid residue is discharged through the slag discharge mechanism. The modification mechanism includes a first motor, a stirring rod, an air pump, an air outlet, an air inlet and a protrusion. After the stirring rod is driven to rotate by the first motor, the tiny particles adhering to the ends of the fibers are increased in flexibility through the interaction of the modifier and the airflow, which changes the basic characteristics of the slag balls and fibers. At the same time, the stirring rod pushes the water to move, and the solution hits the protrusions on the inner wall of the modification tank to form slag balls. Separating from the fibers, the slag balls sink to the bottom of the pool, while the fibers continue to move with the water flow. At the same time, the modifier in the pool softens and modifies the fibers, causing a change in their quality. Simultaneously, through the combined action of the air inlet, air pump, and air outlet, pressurized gas is introduced into the air outlet on the stirring rod, keeping the fibers in a suspended state. The first motor bearing has air holes; after air is introduced from above, pressure is applied to the motor, and the gas is released from the hole in the middle of the bearing and exits through the air outlet on the stirring rod. The simultaneous stirring and air release further suspends the fibers in the water. The bearing is made of seamless steel pipe with a hole in the middle, allowing pressurized gas to be introduced, which can effectively remove the slag balls attached to the ends of the fibers.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

The first motor 201 is located at the upper end of the modification tank 1. The stirring rod 202 is fixedly connected to the rotating shaft of the first motor 201. The air pump 203 is located on the stirring rod 202. The air outlet 204 is located on the stirring rod 202. The number of air outlets 204 is several and evenly distributed. The air inlet 205 is located on the air pump 203. The protrusions 206 are located on the side wall of the modification tank 1. The number of protrusions 206 is several and evenly distributed.

Then, the solid residue is discharged through the slag discharge mechanism 3. The modification mechanism 2 includes a first motor 201, a stirring rod 202, an air pump 203, an air outlet 204, an air inlet 205, and protrusions 206. After the first motor 201 drives the stirring rod 202 to rotate, the tiny particles adhering to the fiber ends are increased in flexibility through the interaction of the modifier and the airflow, changing the basic characteristics of the slag balls and fibers. At the same time, the stirring rod 202 promotes the movement of water, and the solution impacts the protrusions on the inner wall of the modification tank 1. Point 206 separates the slag balls from the fibers. The slag balls sink to the bottom of the pool, while the fibers continue to move with the water flow. At the same time, the modifier in the pool softens and modifies the fibers, resulting in a change in their quality. Simultaneously, through the combined action of the air inlet 205, the air pump 203, and the air outlet 204, pressurized gas is introduced into the air outlet 204 on the stirring rod 202, keeping the fibers in a suspended state. This effectively removes the slag balls attached to the ends of the fibers. The bearing of the first motor 201 has air holes. After air is introduced from above, pressure is applied to the first motor 201, and the gas is released from the hole in the middle of the bearing and exits through the air outlet 204 on the stirring rod 202. The simultaneous stirring and air release further suspends the fibers in the water. The bearing is made of seamless steel pipe with a hole in the middle for the introduction of pressurized gas.

[0034] The working principle of this utility model:

[0035] In use, short fibers are first fed into modification tank 1, where water and a modifier are added. Then, the stirring rod 202 is rotated by the first motor 201. The tiny particles adhering to the fiber ends are softened by the interaction of the modifier and airflow, altering the basic characteristics of the slag balls and fibers. Simultaneously, the stirring rod 202 propels the water, and the solution impacts the protrusions 206 on the inner wall of modification tank 1, separating the slag balls from the fibers. The slag balls sink to the bottom of the tank, while the fibers continue to move with the water flow. Meanwhile, the modifier in the tank softens and modifies the fibers, resulting in a change in their quality. Simultaneously, pressurized gas is introduced into the air outlet 204 on the stirring rod 202 through the combined action of the air inlet 205, the air pump 203, and the air outlet 204, keeping the fibers in suspension. The first spiral auger 301 is effectively removed from the fiber ends. Then, the second motor 303 drives the first spiral auger 301 to rotate, and the third motor 304 drives the second spiral auger 302 to rotate. The second spiral auger 302 can transport the solid residue at the bottom of the modification tank 1 into the second spiral auger 302 through the slag lifting port 305. Then, the solid residue is discharged through the slag outlet 306 on the second spiral auger 302. Then, the fixing frame 4 can fix the first spiral auger 301 and the return water tank 5. When the solid residue enters the return water tank 5, it can be dewatered by the dewatering mesh belt 6. The dewatering mesh belt 6 can filter the water in the solid residue, so that the water enters the return water tank 5. At this time, the water can flow back to the modification tank 1 through the return water port 8, reducing the waste of water resources.
