Its quality and type have an important impact on the quality and performance of the final paper. Pulp is an important raw material in the papermaking industry and is widely used in the production of various types of paper, cardboard, packaging materials and other products.

[0003] Referring to a pre-treatment process for pulp papermaking with Chinese patent publication number CN114263061B, a pulping barrel group is set up, and a pulping barrel is used to hold a waste paper mixture. A pulping device and a cleaning device are set up on the outside of the pulping barrel and are alternately placed in the pulping barrel to stir the waste paper mixture into pulp and remove filaments to purify the pulp. A filter cover is set on the outside of the pulping barrel to control the switching of the inside of the pulping barrel between a sealed state and a pulping state. The reduction motor under the bottom of the pulping barrel is then used to drive the pulping barrel to rotate and centrifugally discharge the pulp, thereby avoiding multiple transfers and dumping of the pulp. Its structure is compact and does not occupy space.

[0019] The present invention also provides a method for processing pulp using an impeller, using a high-concentration centrifugal pulp processing device, and the specific method includes the following steps:

[0020] Step 1: Start the second servo motor to drive the third gear, the fourth gear, the toothed belt and the threaded rod to rotate, thereby moving the connecting block, the sliding sleeve, the top plate and the sealing cover upward, and start the hydraulic rod to push the cylindrical plug upward to penetrate the bottom of the inner cylinder to seal the bottom of the inner cylinder. At the same time, each insertion rod penetrates into the corresponding insertion hole so that the first through holes and the second through holes do not overlap, and the cylinder cover and the protrusion are in a separated state. Then, high-concentration pulp is added into the inner cylinder assembly. After the addition is completed, start the second servo motor again to move the sealing cover downward to seal the top of the processing cylinder mechanism;

[0021] Step 2: Then start the first servo motor to drive the first gear and the impeller mechanism to rotate.

After mixing, start the second servo motor again to pull the impeller mechanism out of the processing drum mechanism, and then adjust the angle between adjacent blades on the blade assembly. During the process, first tighten the bolt to release the lock between the limit ring and the adjustment ring, and then rotate the adjustment ring. The four blade covers and the four blades rotate accordingly, and the blade covers slide along the outside of the blades. After rotating to the required angle, tighten the bolt again to lock the adjustment ring and the limit ring to complete the adjustment of the angle between adjacent blades. After adjustment, start the second servo motor again to move the vertical rod and the blade assembly down into the inner drum assembly and return to their original position.

[0022] Step three, then start the hydraulic rod again, and continue to push the cylindrical plug and the cylinder sleeve upward until the cylinder cover is sleeved on the outside of the protrusion, and at the same time, the first through holes and the second through holes are overlapped one by one, then start the first servo motor to drive the impeller mechanism to rotate. During the process, the second convex plate pushes the first convex plate, causing the inner cylinder assembly to rotate accordingly. Under the action of centrifugal force, the slurry is thrown into the outer cylinder through the first through hole and the second through hole, and finally discharged through the slurry discharge end. Large particles are filtered and intercepted in the inner cylinder assembly. Finally, start the hydraulic rod, remove the sealing plug, pull the cylindrical plug down to complete the separation from the inner cylinder, so that the large particles are discharged through the through groove and finally discharged to the outside of the outer cylinder, completing the separation of slurry and large particles in the pulp.

[0023] Preferably, the adjustment ring is rotatably sleeved on the outside of the vertical rod, and the limiting ring is fixedly sleeved on the outside of the vertical rod.

[0024] Beneficial effects

[0025] The present invention provides a high-concentration centrifugal pulp processing device and a method for processing pulp using an impeller. Compared with the prior art, it has the following advantages:

[0026] 1. A high-concentration centrifugal pulp processing equipment and a method for processing pulp using an impeller. Through the mutual cooperation between the protrusion, the first protrusion plate, the cylinder cover and the second protrusion plate, the hydraulic rod is started to control the horizontal position of the cylinder sleeve and the first protrusion plate, which can realize rapid switching between different processing states of the pulp in the processing cylinder mechanism, realize efficient pulp stirring, separation and discharge of large particles, and improve production efficiency. When it is necessary to separate the slurry and large particles in the pulp, it is only necessary to start the hydraulic rod to push the cylinder sleeve and the first protrusion plate upward, so that the first through holes and the second through holes overlap one by one, and the first protrusion plate and the second protrusion plate are at the same horizontal height. Then, the first servo motor is started to drive the impeller mechanism and the inner cylinder assembly to rotate together, and quickly switch to the state of separating the pulp.

[0027] 2. A high-concentration centrifugal pulp processing device and a method for processing pulp using an impeller. By setting up two blade assemblies at different levels, the opportunity for pulp to contact the blade assemblies is increased, and the pulp is fully processed in different areas of the inner barrel assembly. This not only accelerates the stirring and centrifugal separation processes, but also ensures the uniformity of the pulp during the stirring and centrifugal separation processes, avoiding product quality problems caused by uneven treatment.

[0028] 3. A high-concentration centrifugal pulp processing equipment and a method for processing pulp using an impeller. Through the mutual cooperation between the vertical rod assembly, blades, blade covers and adjustment rings, the angle between adjacent blades can be flexibly and conveniently adjusted according to the type and concentration of the pulp. At the same time, the total length of the blades and blade covers can be adjusted, thereby changing the flow path and speed of the pulp in the equipment, more effectively separating the slurry and large particles in the pulp, improving the separation effect, and accelerating the processing speed of the pulp.

[0029] 4. A high-concentration centrifugal pulp processing equipment and a method for processing pulp using an impeller. Through the mutual cooperation between the second side hole, the inner rod, the first side hole and the circular tube, when the blade assembly needs to be cleaned, it is only necessary to adjust the angle between adjacent blades in advance so that the total length of the blade and the blade cover reaches the maximum value, and keep the blade and the blade cover connected so that they do not separate. Then, the screw is screwed to move the connecting plate, the circular tube and the inner rod downward. During the process, the scale groove is observed until the inner rod is moved down to the required value. At this time, the first side holes and the second side holes coincide with each other. Then, the hose is connected to the external water source, the external pump body is started, and the external water is sucked into the inner rod through the hose and finally sprayed out through each second side hole. At the same time, the first servo motor works to drive the blade assembly to rotate, and the second side hole sprays high-pressure water flow, first flushing the surface of the adjacent blade cover and blades, which can quickly rinse away the adhered dirt, thereby achieving efficient and sufficient cleaning of the blades and blade cover. Afterwards, the water flow can also flush the inner wall of the processing cylinder mechanism to avoid water waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Step 1: Start the second servo motor 11 to drive the third gear 12, the fourth gear 15, the toothed belt 16 and the threaded rod 14 to rotate, thereby moving the connecting block 18, the sliding sleeve 20, the top plate 6 and the sealing cover 4 upward, start the hydraulic rod 2, push the cylindrical plug 3211 upward to penetrate the bottom of the inner cylinder 321, and seal the bottom of the inner cylinder 321. At the same time, each insertion rod 324 penetrates into the corresponding insertion hole 329, so that the first through holes 322 and the second through holes 327 do not overlap, and the cylinder cover 715 and the protrusion 3212 are in a separated state. Then, high-concentration pulp is added into the inner cylinder assembly 32. After the addition is completed, start the second servo motor 11 again to move the sealing cover 4 downward to seal the top of the processing cylinder mechanism 3;

[0058] 726, and the second servo motor 11 is started again after the mixing is completed, so that the impeller mechanism 7 is pulled out from the processing drum mechanism 3, and then the angle between the adjacent blades 723 on the blade assembly 72 is adjusted. During the process, the bolt 729 is first screwed to release the lock between the limit ring 728 and the adjustment ring 726, and then the adjustment ring 726 is rotated, and the four blade covers 724 and the four blades 723 rotate accordingly. At the same time, the blade cover 724 slides along the outside of the blade 723. After rotating to the required angle, the bolt 729 is screwed again to lock the adjustment ring 726 and the limit ring 728, completing the adjustment of the angle between the adjacent blades 723. After the adjustment is completed, the second servo motor 11 is started again to move the vertical rod 711 and the blade assembly 72 downward into the inner drum assembly 32 and return to its original position.

[0059] 3. Then start the hydraulic rod 2 again, and continue to push the cylindrical plug 3211 and the cylinder sleeve 326 upward until the cylinder cover 715 is sleeved on the outside of the protrusion 3212, and at the same time, the first through holes 322 and the second through holes 327 are overlapped one by one, then start the first servo motor 8 to drive the impeller mechanism 7 to rotate. During the process, the second convex plate 716 pushes the first convex plate 3213, causing the inner cylinder assembly 32 to rotate accordingly. Under the action of centrifugal force, the slurry is thrown into the outer cylinder 31 through the first through hole 322 and the second through hole 327, and finally discharged through the pulp discharge end 33. Large particles are filtered and intercepted in the inner cylinder assembly 32. Finally, start the hydraulic rod 2, remove the sealing plug 34, pull the cylindrical plug 3211 down to complete the separation from the inner cylinder 321, and discharge the large particles through the through groove 328, and finally discharge to the outside of the outer cylinder 31, completing the separation of slurry and large particles in the pulp.

At the same time, each insertion rod penetrates into the corresponding insertion hole so that the first through holes and the second through holes do not overlap, and the cylinder cover and the protrusion are in a separated state. Then, high-concentration pulp is added into the inner cylinder assembly. After the addition is completed, start the second servo motor again to move the sealing cover downward to seal the top of the processing cylinder mechanism; Step 2: Then start the first servo motor to drive the first gear and the impeller mechanism to rotate. The impeller mechanism stirs the pulp during the rotation and mixes the fibers and other components in the pulp evenly. After mixing, start the second servo motor again to pull the impeller mechanism out of the processing drum mechanism, and then adjust the angle between adjacent blades on the blade assembly. During the process, first tighten the bolt to release the lock between the limit ring and the adjustment ring, and then rotate the adjustment ring. The four blade covers and the four blades rotate accordingly, and the blade covers slide along the outside of the blades. After rotating to the required angle, tighten the bolt again to lock the adjustment ring and the limit ring to complete the adjustment of the angle between adjacent blades. After adjustment, start the second servo motor again to move the vertical rod and the blade assembly down into the inner drum assembly and return to their original position. Step three, then start the hydraulic rod again, and continue to push the cylindrical plug and the cylinder sleeve upward until the cylinder cover is sleeved on the outside of the protrusion, and at the same time, the first through holes and the second through holes are overlapped one by one, then start the first servo motor to drive the impeller mechanism to rotate. During the process, the second convex plate pushes the first convex plate, causing the inner cylinder assembly to rotate accordingly.

Large particles are filtered and intercepted in the inner cylinder assembly. Finally, start the hydraulic rod, remove the sealing plug, pull the cylindrical plug down to complete the separation from the inner cylinder, so that the large particles are discharged through the through groove and finally discharged to the outside of the outer cylinder, completing the separation of slurry and large particles in the pulp.
