Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a papermaking pulp deslagging device. Background Technology

[0002] According to the patent document with publication number CN222861953U, a servo motor drives a rotating shaft and a connecting rod to disperse the raw materials with a dispersing fan blade. At the same time, when the rotating rod rotates, the fixed rod drives the connecting ring to rotate. Through the power transmission of the transmission gear, the second fixed ring drives the dispersing fan blade of the separation cylinder to rotate in opposite directions when the connecting ring rotates. Then, the centrifugal force of the rotating separation cylinder discharges the residue through the slag discharge hole.

[0003] The patent document states that when the dispersing fan blades and the separation cylinder rotate in opposite directions, the rotation of the dispersing fan blades inside the separation cylinder will create multiple turbulent flows, resulting in a more chaotic liquid flow direction inside the separation cylinder. Consequently, the centrifugal force on the residue is less pronounced, and more pulp may be coated on the outside of the residue. Therefore, the overall slag removal and separation effect will not be significant. At the same time, the entire structure will place a relatively large load on the rotating shaft during use, accelerating the aging of the equipment and increasing the probability of failure.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a paper pulp deslagging device includes a deslagging mechanism 1, a settling mechanism 2, and a filtering mechanism 3. The settling mechanism 2 is located below the deslagging mechanism 1, and the filtering mechanism 3 is located inside the settling mechanism 2.

[0030] In this embodiment: the slag removal mechanism 1 includes a slurry inlet pipe 11, with multiple conical cylinders 13 fixed on both sides of the slurry inlet pipe 11. A slag outlet bend 14 is fixed at the lower end of the conical cylinder 13, and a slurry outlet pipe 15 is fixed at the center of the top of the conical cylinder 13, with the lower end of the slurry outlet pipe 15 extending into the interior of the conical cylinder 13. Each conical cylinder 13 is connected to the slurry inlet pipe 11 through a guide pipe 12. The end of the guide pipe 12 away from the slurry inlet pipe 11 is fixedly connected to the tangential position at the upper end of the conical cylinder 13. The slurry containing slag in the slurry inlet pipe 11 is fed into the corresponding conical cylinder 13 by the multiple guide pipes 12. At this time, the slurry entering the conical cylinder 13 will spiral downward along the side wall of the conical cylinder 13. During this process, the debris in the slurry will be subjected to increased centrifugal force and adhere to the side wall of the conical cylinder 13. At the same time, under the action of gravity, the debris will spiral downward along the side wall of the conical cylinder 13 and fall into the slag discharge bend 14. At this time, the debris in the slag discharge bend 14 will enter the settling mechanism 2, while the slurry at the center of the conical cylinder 13 will flow upward in the opposite direction to the slurry discharge pipe 15. Then the slurry can be sent out from the top of the slurry discharge pipe 15, thus completing the entire slag removal process.

[0031] In this embodiment: the settling mechanism 2 includes a settling cylinder 21, with multiple electric ball valves 22 fixed on both sides of the settling cylinder 21, a settling discharge valve 23 fixed at the discharge end of the settling cylinder 21, and multiple slag collection troughs 24 fixed on the lower side of the settling cylinder 21. Each slag collection trough 24 has a plate 25 inserted into its lower end, and the lower end of each slag discharge bend 14 is fixedly connected to the corresponding electric ball valve 22. By opening the electric ball valve 22, the slag aggregated in the conical cylinder 13 due to centrifugal force passes through the discharge bend. The slag bend 14 is introduced into the settling cylinder 21. At the same time, the slag entering the settling cylinder 21 will gather and settle at the bottom of the settling cylinder 21 due to gravity. Then, when the settling discharge valve 23 is opened, the slurry in the settling cylinder 21 will flow out from the settling discharge valve 23. At the same time, the slag gathered at the bottom of the settling cylinder 21 will flow with the slurry and fall into the slag collection trough 24. At this time, the slag entering the slag collection trough 24 will gather at the top of the insert plate 25.

[0032] In this embodiment: the filter mechanism 3 includes a rotating shaft 35, one end of which is rotatably connected to the settling cylinder 21, and the other end of which is fixed with a blade 6. Multiple filter plates 31 are sleeved on the outside of the rotating shaft 35. A toothed ring 32 is fixed to one side of each filter plate 31, and a push ring 33 is provided on one side of the toothed ring 32. Multiple push seats 34 are fixed to the side of the push ring 33 closest to the toothed ring 32, and the multiple push seats 34 are arranged in a ring around the rotating shaft 35. A moving ring 4 is fixed to the other side of the filter plate 31, and a stationary ring 5 is provided on the side of the moving ring 4 away from the filter plate 31. A fixed ring 36 is provided on the side away from the moving ring 4. The fixed ring 36 is fixedly connected to the other end of the rotating shaft 35. Both the moving ring 4 and the stationary ring 5 are sleeved on the outside of the rotating shaft 35. A toothed ring 32 has a toothed opening on one side and is sleeved on the outside of the rotating shaft 35. The fixed ring 36 is fixedly connected to the rotating shaft 35. Each push ring 33 is fixedly connected to the rotating shaft 35. Four guide bars are fixed on the inner wall of the settling cylinder 21, and the four guide bars are arranged in a ring around the rotating shaft 35. The outer side of the filter plate 31 has a notch for sliding on the four guide bars. Each filter plate 31 All are located on the other side of their corresponding slag collection trough 24. The bottom of the slag collection trough 24 is an open structure, and the lower side of the slag collection trough 24 has an insertion port for inserting the insert plate 25. The slurry flowing out of the settling cylinder 21 drives the blade 6 to rotate. At the same time, the blade 6 drives the rotating shaft 35 to rotate synchronously inside the settling cylinder 21. During the rotation of the rotating shaft 35, the rotating shaft 35 drives the push ring 33 and the push seat 34 to rotate synchronously. Because the notch of the filter plate 31 cooperates with the guide strip of the settling cylinder 21, the rotating shaft 35 rotates... When the push ring 33 is in motion, it will drive the push seat 34 to push the toothed ring 32. At this time, the toothed ring 32 will drive the filter plate 31 to slide away from the push ring 33 along the rotation axis 35. During this process, the filter plate 31 will simultaneously drive the moving ring 4 to squeeze the stationary ring 5. When the push seat 34 rotates past the toothed ring 32, the stationary ring 5 pushes the moving ring 4 and the filter plate 31 to slide quickly back to the push ring 33 along the rotation axis 35. By repeating the above steps, the debris blocking the filter plate 31 can be shaken off, and the shaken debris will fall into the slag collection trough 24.

[0033] Working principle: In operation, the required slurry is first fed into the slurry inlet pipe 11. Multiple guide pipes 12 then guide the slurry containing debris from the inlet pipe 11 into the corresponding conical cylinder 13. The slurry entering the conical cylinder 13 spirals downwards along its side wall. During this process, the debris in the slurry is subjected to increased centrifugal force and adheres to the side wall of the conical cylinder 13. Simultaneously, under the influence of gravity, the debris spirals downwards along the side wall of the conical cylinder 13 and falls into the slag outlet bend 14. Meanwhile, the slurry at the center of the conical cylinder 13 flows upwards in the opposite direction into the slurry outlet pipe 15. The slurry can then be discharged from the top of the slurry outlet pipe 15. Additionally, opening the electric ball valve 22 allows the debris collected in the conical cylinder 13 due to centrifugal force to be introduced into the settling cylinder 21 through the slag outlet bend 14. Simultaneously, the debris entering the settling cylinder 21 will gather and settle at the bottom due to gravity. Then, when the settling discharge valve 23 is opened, the slurry in the settling cylinder 21 will flow out through the valve, and the debris collected at the bottom of the settling cylinder 21 will flow with the slurry. At this time, the filter plate 31 will filter the debris in the slurry. During this process, the slurry flows from the settling cylinder 21 to... The outflowing power drives the blades 6 to rotate, and the blades 6 simultaneously drive the rotating shaft 35 to rotate synchronously inside the settling cylinder 21. During this rotation, the rotating shaft 35 drives the push ring 33 and the push seat 34 to rotate synchronously. Because the notch of the filter plate 31 cooperates with the guide strip of the settling cylinder 21, when the rotating shaft 35 rotates, the push ring 33 will drive the push seat 34 to push the toothed ring 32. At this time, the toothed ring 32 will drive the filter plate 31 to slide away from the push ring 33 along the rotating shaft 35. During this process, the filter plate 31 will synchronously drive the moving ring 4 to squeeze the stationary ring 5. When the pusher seat 34 rotates past the teeth of the toothed ring 32, the stationary ring 5 pushes the moving ring 4 and the filter plate 31 to slide quickly back to their original positions along the rotating shaft 35 towards the pusher ring 33. Repeating the above steps will shake off the debris clogging the filter plate 31. The shaken debris will fall into the slag collection trough 24. At this time, the debris entering the slag collection trough 24 will gather at the top of the insert plate 25, thus completing the entire slag removal process. The remaining slurry after slag removal can then be filtered and separated again, thereby reducing the amount of slurry remaining in the debris. In addition, after the slag removal is completed, the debris can be cleaned by pulling out the insert plate 25 on the slag collection trough 24.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
