Description

Technical Field

[0001] This invention relates to the field of papermaking equipment technology, specifically to a pulping and slag removal device with a self-cleaning function. Background Technology

[0002] Recycled papermaking waste can be divided into two main categories: coarse waste and fine waste. Coarse waste mainly comes from the pulping and slag removal stages, and is mostly composed of twisted ropes; while fine waste mainly comes from the washing and screening stages, and can be further divided into light waste and heavy waste. When the heavy waste from papermaking pulping is discharged, it contains a small amount of fiber, resulting in significant waste.

[0003] The existing design involves installing a lower cone-shaped slag remover, which uses the difference in specific gravity between fibers and impurities to separate them. However, these heavy slags contain plastics, metals, and other mixtures, which tend to stick to the wall of the cone-shaped slag remover during the separation process. Over time, this accumulation can affect the slag removal efficiency of the slag remover. Therefore, a self-cleaning slag removal device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a pulping and slag removal device with a self-cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pulping and slag removal device with self-cleaning function, comprising a conical shell, a paper fiber outlet at the top of the conical shell, a heavy slag inlet on the side wall of the conical shell, a waste outlet at the bottom of the conical shell, a lifting cleaning mechanism at the top of the conical shell, and a groove along the shell wall of the conical shell, wherein a movable dustproof mechanism is embedded in the groove, and the dustproof mechanism is located below the cleaning mechanism.

[0006] Preferably, the cleaning mechanism includes an annular pipe with connectors on both sides, each connector being connected to the piston rod of a cylinder, and the cylinder being located on the top outer side of the conical housing;

[0007] The annular pipe is equipped with multiple dual-nozzle rotating nozzles;

[0008] The annular pipe is also equipped with a connection port.

[0009] Preferably, the interface is connected to the conveying pipe, the conveying pipe passes through the conical shell and is connected to an external water pump, and the conveying pipe is also provided with a sealing gasket, which is in contact with the inner wall of the conical shell.

[0010] Preferably, the dustproof mechanism includes a gear ring, with the upper and lower sliding rings of the gear ring respectively embedded in the upper and lower ends of the slot. The outer teeth of the gear ring are located on the outside of the conical shell. The inner ring of the gear ring extends inward in the lower direction to form a mounting platform. The mounting platform is provided with multiple small gears, and the multiple small gears mesh with the inner teeth of the inner wall of the gear ring. Each small gear is also provided with an arc-shaped blade, and the multiple blades overlap to form an iris mechanism.

[0011] Preferably, the conical shell is further provided with a mounting plate, the mounting plate is provided with a rotary motor, the rotating shaft of the rotary motor is connected to a drive gear, the drive gear meshes with the outer teeth of the gear ring, when the rotary motor rotates, the drive gear drives the gear ring to rotate, thereby driving the inner small gear to rotate, so that the engagement and disengagement of the overlapping blades changes the size of the central circular hole.

[0012] After the aperture becomes smaller, it fits into the paper fiber outlet, and at this time, the multiple blades form a baffle to block impurities;

[0013] The enlarged aperture creates a through-hole, facilitating the lifting and lowering of the cleaning mechanism for cleaning.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure and a novel design. The specially designed lifting cleaning mechanism moves up and down to spray, thereby rinsing the inner wall of the conical shell. By regularly removing the impurities accumulated on the inner wall, the subsequent slag removal effect can be effectively improved.

[0015] In addition, after the cleaning mechanism finishes its work, a specially designed movable dustproof mechanism can be closed to block the cleaning mechanism and prevent impurities from entering the cleaning mechanism and clogging the nozzles during the slag removal process.

[0025] Please see Figure 1-6 The present invention provides a technical solution: a pulping and deslagging device with self-cleaning function, comprising a conical shell 1. Heavy slag enters the deslagging device through a heavy slag inlet 12 provided on the side wall of the conical shell 1 and rotates at high speed inside the conical shell 1. Due to the difference in centrifugal force between heavy impurities and fibers, heavy impurities are thrown towards the shell wall and, under the action of gravity, gradually move towards the waste outlet 13 provided at the bottom of the conical shell 1. Fibers, due to their smaller centrifugal force, gradually move towards the central low-pressure area, and after reaching the bottom, spiral upwards, and are finally discharged through the paper fiber outlet 11 provided at the top of the conical shell 1.

[0026] To facilitate regular self-cleaning of the slag removal equipment, a lifting cleaning mechanism 2 is provided at the top of the conical shell 1, and a groove 14 is formed along the shell wall of the conical shell 1, in which a movable dustproof mechanism 3 is embedded.

[0027] Since the dustproof mechanism 3 is located below the cleaning mechanism 2, when it is necessary to clean the inside of the slag removal equipment, the dustproof mechanism 3 is opened and the heavy slag inlet 12 is closed. Then the cleaning mechanism 2 can be started to move up and down and spray, thereby rinsing the inner wall of the conical shell. The cleaned waste material moves down the cone and is discharged from the waste outlet 13.

[0028] In this embodiment, the cleaning mechanism 2 includes an annular pipe 21, with connectors 22 on both sides of the annular pipe 21, a plurality of dual-nozzle rotating nozzles 24 on the annular pipe 21, and a docking port 211 on the annular pipe 21.

[0029] Both cylinders 23 (which can be multi-section telescopic cylinders) are mounted on the outer top of the conical housing 1, with the piston rod ends of the cylinders extending into the conical housing 1 and connecting to the corresponding connecting parts 22.

[0030] Then connect the interface 211 to the conveying pipe 25, which passes through the conical shell 1 and is connected to an external water pump. When the cleaning mechanism 2 is at the top of the conical shell 1, the sealing gasket 251 on the conveying pipe 25 is in contact with the inner wall of the conical shell 1.

[0031] When the water pump is started, the delivery pipe 25 sends water into the annular pipe 21, and the double-nozzle rotating nozzle 24 sprays water while rotating. Then, the cylinder extends and retracts to drive the annular pipe 21 to move up and down inside the conical shell 1, so that the inner wall of the conical shell can be rinsed back and forth.

[0032] In this embodiment, the dustproof mechanism 3 includes a gear ring 31, with the upper and lower sliding rings 311 of the gear ring 31 respectively embedded in the upper and lower ends of the slot 14, and the outer teeth 312 of the gear ring 31 positioned on the outside of the conical shell 1.

[0033] The inner ring of the gear ring 31 extends inward from the lower direction to a mounting platform 313, on which multiple pinions 32 are connected, ensuring that all pinions 32 mesh with the internal teeth 314 on the inner wall of the gear ring 31.

[0034] Then, an arc-shaped blade 33 is set on each pinion 32, and multiple blades 33 overlap to form an iris mechanism;

[0035] A mounting plate 15 is provided on the conical housing 1, the rotary motor 4 is mounted on the mounting plate 15, and then a drive gear 41 is connected to the rotating shaft of the rotary motor 4, ensuring that the drive gear 41 meshes with the external teeth 312 of the gear ring 31.

[0036] When the rotary motor 41 rotates, the drive gear 41 drives the gear ring 31 to rotate, which in turn drives the inner pinion 32 to rotate, causing the overlapping blades 33 to engage and disengage, thereby changing the size of the central circular aperture.

[0037] When the aperture becomes smaller, it comes into contact with the paper fiber outlet 11. At this time, the multiple blades 33 form a baffle to block impurities.

[0038] With the aperture enlarged, a through hole is formed, facilitating the lifting and lowering of the cleaning mechanism 2 for cleaning.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
