Description

Technical Field

[0001] This invention relates to the field of scum removal devices, and particularly to a recycling and regeneration device for paper product waste. Background Technology

[0002] In the recycling and regeneration process of waste paper and paper products, the first step is to put the waste paper into a pulping tank and stir it at high speed to disperse the paper fibers into a pulp. Then, the stirring is stopped to allow the pulp to settle and separate into layers. Hydrophobic and lightweight impurities such as ink, plastic film fragments, and adhesives float to the surface because their density is lower than that of water, forming a layer of floating impurities. These impurities need to be separated from the lower layer of good pulp before they can enter the subsequent recycling process.

[0003] Currently, automated cleaning of floating debris generally employs a wastewater settling tank intelligent retrieval device disclosed in CN222358015U. This device includes lateral moving structures installed at both ends of the settling tank for moving supports, and a longitudinal moving structure installed between the two supports. The lateral moving structure and the longitudinal moving structure are arranged perpendicularly, and the longitudinal moving structure is used to move the hanger. The hanger is equipped with a lifting plate via a lifting structure, and the hanging plate is equipped with a retrieval frame via a rotating structure.

[0004] When the above-mentioned salvage device salvages the floating debris layer of the present invention, when the salvage frame is controlled to move horizontally in one direction during operation, as the salvage frame is pushed on the water surface, the front of the frame squeezes the surface water to form a surface shear flow. The floating debris on both sides of the opening is pushed away by the surface flow to the periphery and rear of the frame. When the salvage frame moves to the next station, the surface flow field of the cleared area loses the obstruction of the frame and swings back. The pushed-away floating debris is then backfilled into the position that was just cleared, resulting in the problem that the desired salvage effect cannot be achieved in a single operation. Summary of the Invention

[0005] This invention provides a recycling and regeneration device for paper product waste, which can solve the problem that a single retrieval action in the prior art cannot complete the required retrieval effect.

[0008] Furthermore, the lifting device includes a pair of parallel vertical plates, the inner wall of the vertical plates is provided with a rectangular groove, and the side of the rectangular groove away from the second linear moving structure is provided with a rectangular slot; the outer wall of the retrieval box is provided with a protrusion, and the protrusion slides into the rectangular groove along one end of the rectangular groove and then gets stuck in the rectangular slot.

[0009] Furthermore, at least one end of the isolation rod and the inner wall of the pulping tank form a channel for the retrieval box to pass through, and the isolation rod is connected to the bottom side of the pulping tank by a vertical rod.

[0010] Furthermore, the retrieval box includes a box body, with a protrusion installed on each of the two opposite outer side walls of the box body; a rectangular feed inlet is provided on one side of the box body, and a guide plate is provided at each end of the feed inlet, with the two guide plates arranged in a figure-eight shape; a filter element is supported in the box body below the feed inlet, and a pump is provided in the box body below the filter element, the pump being used to discharge the liquid collected in the box body from the box body.

[0011] Furthermore, the inner wall of the housing is provided with a convex ring for supporting the filter element. The filter element includes a filter frame, and the top of the filter frame is provided with a flange that rests on the convex ring. A pair of operating rods are fixed on the flange. A drain pipe is provided on the bottom side of the housing, and a drain valve or plug is installed on the drain pipe.

[0012] Furthermore, a rectangular opening is provided on the side wall of the box located directly below the feed inlet, and a sleeve is fixed at the rectangular opening; at least one of the pulping tanks at one end of the strip-shaped retrieval area is provided with an insert plate that is inserted into the sleeve; a drive structure is also provided to drive the insert plate to move in the horizontal and vertical directions.

[0013] Furthermore, the side wall of the pulping tank is provided with an installation cavity for installing a drive structure. The drive structure includes a linear module installed on the top side of the installation cavity. A telescopic cylinder that extends and retracts in the vertical direction is connected to the slider of the linear module. The output end of the telescopic cylinder is connected to the insert plate.

[0014] Furthermore, the end of the insert sleeve is provided with multiple insert tubes that are connected to the pump, and the end face of the insert plate is formed with multiple insert cavities that mate with the insert tubes one by one.

[0016] This invention divides the interior of the slurry tank into multiple independent strip-shaped dredging zones by setting up multiple parallel isolation rods. The dredging box moves within each zone, with some isolation rods submerged in the water and others protruding, effectively blocking the surface water flow generated when the dredging box moves forward. This ensures that the dispersed floating impurities only flow within their designated strip-shaped area and cannot spread to adjacent areas, thus preventing impurities from backfilling and causing cross-zone pollution. At the same time, it breaks down the large-area dredging task into multiple localized tasks in narrow areas. Each area has a smaller volume of water and impurities, allowing the dredging box to complete a thorough cleaning in a single pass, reducing the number of repetitive operations and improving work efficiency. Furthermore, due to the improved effectiveness and reliability of each operation, multiple repeated dredging operations are unnecessary, thereby reducing the operating load and energy consumption of the moving mechanism and extending the service life of the equipment.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1 In the pulping process of waste paper recycling, the layer of floating impurities formed in pulping tank 1 needs to be efficiently and cleanly removed. Existing retrieval devices move the retrieval frame indiscriminately across the entire tank surface without any zoned isolation. The disturbance generated during retrieval affects the entire tank surface, causing floating impurities to migrate and mix over a wide area. Due to the lack of effective isolation measures, the disturbance generated when the retrieval frame pushes the water surface pushes the floating impurities to the surrounding areas. Furthermore, after the retrieval frame leaves the retrieval station, the floating impurities on the periphery of the original retrieval station quickly flow back to the retrieval station. This results in incomplete cleaning or poor cleaning effect when controlling the retrieval frame to sweep the entire pulping tank 1 horizontally. Additionally, because the impurities are dispersed and then backfilled, a single sweep cannot achieve the desired cleaning effect. Multiple repetitive operations are often required, reducing work efficiency and increasing energy consumption and equipment wear.

[0021] To solve the above problems, such as Figure 1-2 As shown in the figure, an embodiment of the present invention provides a recycling device for paper product waste, including a pulping tank 1 and a retrieval mechanism disposed in the pulping tank 1. The retrieval mechanism mainly includes a retrieval box 2.

[0022] Multiple parallel isolation rods 11 are fixedly installed inside the slurry tank 1. These isolation rods 11 are arranged along the length of the slurry tank, dividing the internal space of the slurry tank 1 into several independent and narrow strip-shaped retrieval areas. The lower part of each isolation rod 11 is fixed to the bottom surface of the slurry tank 1 by a vertical rod 12, and its upper part is submerged below the water surface, while the upper part protrudes above the water surface. Driven by the moving component, the retrieval box 2 moves from one end to the other within the strip-shaped retrieval area during a single operation. In actual operation, a liquid level indicator rod needs to be installed in the slurry tank 1. The observer can observe the liquid level in the slurry tank 1 through the liquid level indicator rod, thereby facilitating timely control of the liquid level height in the slurry tank 1.

[0023] It should be emphasized that the core improvement of this embodiment is that the slurry tank 1 is divided into multiple independent strip-shaped dredging areas by the isolation rods 11. When the dredging box 2 is performing dredging operations in a strip-shaped dredging area, the surface water flow generated by its forward movement is effectively blocked by the isolation rods 11 on both sides, so that the dispersed floating impurities can only flow in this narrow area and cannot cross the isolation rods 11 to spread to the adjacent strip-shaped dredging areas. When the dredging box 2 leaves the area, even if some impurities flow back, it is limited to this strip-shaped dredging area. Floating impurities floating on the surface of other adjacent strip-shaped dredging areas cannot cross the isolation rods 11 to enter this strip-shaped dredging area. That is, floating impurities floating on the surface of adjacent strip-shaped dredging areas will not pollute the already cleaned strip-shaped dredging area.

[0024] This invention breaks down the large-area retrieval task of the entire pool surface into local retrieval tasks in multiple independent, narrow strip areas. The amount of water and impurities in each area is relatively small, and the retrieval box 2 can complete the thorough cleaning of the area in one pass, which significantly improves the effectiveness and reliability of a single operation.

[0025] As can be seen, in one specific embodiment, both ends of the isolation rod 11 and the inner wall of the pulping tank 1 form a channel for the retrieval box 2 to pass through, and the isolation rod 11 is connected to the inner bottom side of the pulping tank 1 by the vertical rod 12.

[0026] At this time, the retrieval box 2 is positioned inside the pulping tank 1 as follows: Figure 2 As shown in the S-shaped path, it can be seen that the direction of movement of the salvage box 2 changes during this S-shaped path movement. Therefore, in actual operation, it is also necessary to control the rotation of the salvage box 2 to adjust its orientation.

[0027] Meanwhile, in order to achieve the following: the retrieval box 2 moves along the inside of the pulping tank 1... Figure 2The S-shaped path shown is used to complete the salvage and cleaning operation of the entire water surface. The salvage mechanism also includes a moving component, which includes a pair of parallel first linear moving structures 10. A second linear moving structure 20 is mounted on the moving part of the two first linear moving structures 10. A rotating part is installed on the moving part of the second linear moving structure 20. A lifting device is installed at the output end of the rotating part. The salvage box 2 is detachably installed on the lifting device. The running directions of the first linear moving structure 10 and the second linear moving structure 20 are perpendicular to each other, thereby realizing movement in the XY plane. The first linear moving structure 10 and the second linear moving structure 20 are selected from ball screw modules.

[0028] Example 2 It is understandable that in Embodiment 1, the retrieval box 2 needs to move frequently in different areas, and the amount of material carried inside the retrieval box 2 is limited. Therefore, in actual operation, it is necessary to frequently remove the retrieval box 2 and empty the impurities collected inside the retrieval box 2.

[0029] Based on this, this embodiment needs to solve the problem of quick assembly and disassembly of the salvage box 2 and the lifting device. The lifting device provided in this embodiment includes a pair of parallel vertical plates 201, and a horizontal plate is installed on the top of the two vertical plates 201. The horizontal plate is fixed to the output end of the rotating component, and the rotating component is a geared motor.

[0030] Meanwhile, an L-shaped slide is machined on the inner wall of the vertical plate 201. The slide consists of a horizontal rectangular groove 202 and a rectangular slot 203 located at the end of the rectangular groove 202. Correspondingly, a protrusion 211 is fixedly installed on each of the two opposite outer walls of the body 21 of the retrieval box 2. During installation, the protrusion 211 on the retrieval box 2 is aligned with the entrance of the rectangular groove 202 on the vertical plate 201 and then pushed horizontally until the protrusion 211 slides into the rectangular slot 203 at the end, thus completing the locking. During disassembly, the retrieval box 2 is simply lifted slightly to disengage the protrusion 211 from the rectangular slot 203 and then pulled out in the opposite direction.

[0031] The embodiments of the present invention adopt a quick-assembly and disassembly structure composed of protrusions and slots, replacing the traditional bolt connection or complex snap-fit ​​structure; the operator can complete the installation and disassembly of the retrieval box 2 in a few seconds without the aid of tools, which greatly facilitates the maintenance of the equipment and the cleaning of impurities.

[0032] To further improve salvage efficiency, such as Figure 3-5 As shown, at both ends of the feed inlet 22 of the box 21, there are also guide plates 221 that open outward in a figure-eight shape; these two guide plates 221 can form a gradually narrowing collection port on the water surface, guiding a larger range of floating impurities into the feed inlet 22.

[0033] It is known that, in order to prevent the salvage box 2 from accidentally falling off during movement, a locking pin controlled by an electromagnet is added inside the rectangular slot 203; when the protrusion 211 slides into the slot 203, the control system automatically triggers the electromagnet, the locking pin pops out and locks into the recess on the protrusion 211, realizing automatic locking; when disassembly is required, the control system is powered off, the locking pin is reset, and it can be easily removed.

[0034] Meanwhile, the guide plate 221 is connected to the box 21 via a hinge and is driven by a micro servo motor. The control system can adjust the opening and closing angle of the guide plate 221 in real time according to the traveling speed of the retrieval box 2, the water surface velocity, and the distribution density of floating debris, so as to optimize the water flow guidance effect while ensuring the collection width.

[0035] Example 3 Understandably, after collecting a large amount of water-containing floating impurities, the retrieval box 2 will accumulate a large amount of liquid inside. If it is not drained in time, it will not only increase the weight of the retrieval box and affect the load on the moving mechanism, but also make it difficult to separate solids and liquids during subsequent processing.

[0036] To address the aforementioned liquid discharge problem, this embodiment provides an automated liquid discharge docking structure; such as... Figure 5-7 On the side wall of the retrieval box 21, directly below the feed inlet 22, a sleeve 25 is fixed. On the side wall of the pulping tank 1, corresponding to the end of a certain strip-shaped retrieval area, a movable insert plate 3 is provided. A drive structure is also provided to drive the insert plate 3 to move in the horizontal and vertical directions. The drive structure includes a linear module 31 and a telescopic cylinder 32 installed in the mounting cavity 13 on the side wall of the pulping tank 1. The linear module 31 can drive the insert plate 3 to move horizontally, and the telescopic cylinder 32 can drive the insert plate 3 to move vertically. The cylinder body of the telescopic cylinder 32 is fixed on the slider of the linear module 31.

[0037] During operation, when the retrieval box 2 moves to the end of the strip-shaped retrieval area, the control system first controls the linear module 31 and the telescopic cylinder 32 to adjust the insert plate 3 to a position aligned with the insert sleeve 25. Then, the telescopic cylinder 32 extends and inserts the insert plate 3 horizontally into the insert sleeve 25.

[0038] The insert 25 has multiple tubes 26 inside that connect to the pump inside the housing 21; the end face of the insert plate 3 has insert cavities 30 that correspond one-to-one with the tubes 26; when the insert plate 3 is inserted into place, the tubes 26 are inserted into the insert cavities 30, thereby connecting the drain pipe inside the housing 21 with the drain pipes 33 on the insert plate 3. The drain pipes 33 eventually converge into a main pipe, discharging the liquid into the collection tank.

[0039] It should be emphasized that the core improvement of this embodiment is that the automatic and rapid docking between the retrieval box 2 and the insert plate 3 is achieved through the cooperation of the insert plate 3 and the insert sleeve 25. After the retrieval box 2 is in place, the system can automatically complete the connection of the drainage pipe and discharge the liquid in the box without the need for manual connection. The whole process is highly automated, which greatly reduces the labor intensity of workers and improves the continuous operation capability of the equipment.

[0040] To prevent water from entering the insertion cavity 30 in the unconnected state of the retrieval pool 1, a sealing and conduction mechanism is provided inside the insertion cavity 30. This sealing and conduction mechanism includes a fixing part 301, on which a T-shaped limiting rod 302 and a spring 303 are connected. The spring 303 is connected to a movable plate 304. In the natural state, the movable plate 304 is pressed and sealed by the head of the T-shaped limiting rod 302, thus sealing the insertion cavity 30. A top rod 305 is also fixed on the fixing part 301. It passes through a through hole on the movable plate 304, and sealing fins are provided on the inner wall of the through hole.

[0041] The end face of the insertion tube 26 is provided with an insertion hole facing the position of the push rod 305. The bottom side of the insertion hole is connected to the pressure sensor 262 through the elastic telescopic member 261. When the insertion tube 26 is inserted into the insertion cavity 30, the push rod 305 is inserted into the insertion hole.

[0042] When the insertion tube 26 is inserted into the insertion cavity 30, the sealing layer 263 on its end face first contacts and presses against the movable plate 304 to seal it. As the insertion tube 26 continues to penetrate deeper, the insertion hole on the end face of the insertion tube 26 will fit the push rod 305, and the push rod 305 will then push open the movable plate 304, opening the internal passage of the insertion cavity 30. At the same time, the pressure sensor 262 inside the insertion tube 26 will sense the pressure of the push rod 305, thereby sending a signal to the control system to confirm successful docking. Then, the pump will be started to pump liquid into the insertion tube 26. This design ensures that the drain pipe is normally closed when not docked, preventing liquid leakage. When docked, it can reliably conduct and provide feedback signals of docking status.

[0043] It is known that floating impurities include not only ink, but also plastic film fragments, adhesives, etc. If the pump is used to directly pump mixtures including ink, plastic film fragments, adhesives, water, etc., the film will wrap around the impeller and the adhesives will clog the flow channel, which can easily cause the pump to burn out.

[0044] To solve the above problems, the present invention requires preliminary solid-liquid separation of the mixture collected in the retrieval box 2 to intercept large-sized impurities such as plastic film fragments and adhesives, and to prevent them from being sucked into the pump and causing blockage. Therefore, a filter element 24 is supported in the box body 21, located directly below the feed inlet 22. The pump is installed in the box body 21 below the filter element 24, with its inlet located below the filter element 24. The pump body can be fixed to the outer wall or bottom of the box body 21.

[0045] Specifically, such as Figure 2 , Figure 3 As shown, the inner wall of the housing 21 is integrally formed or welded with a convex ring 23 for supporting the filter element 24; the filter element 24 includes a filter frame, the top of which extends outward to form a flange, which rests on the convex ring 23 to support the filter element; a pair of vertically upward operating rods are fixed on the flange, the upper end of which extends to the vicinity of the top opening of the housing 21, and the operator can lift the filter element 24 as a whole by holding the operating rods for cleaning or replacing the filter screen.

[0046] The filter mesh size of the filter element 24 is preferably 3 to 8 mm, which can effectively trap plastic film debris and adhesive clumps without causing frequent clogging due to excessively small pore size. To further adapt to working conditions with highly viscous adhesives, the filter mesh material can be stainless steel woven mesh or perforated plate, with a polytetrafluoroethylene coating sprayed on the surface to reduce adhesion.

[0047] A drain pipe 27 is provided on the bottom side of the housing 21, and a drain valve or plug is installed on the drain pipe 27. During normal operation, the drain valve is closed and the pump is started to discharge the filtered clear liquid through the sleeve 25, the plate 3 and other pipelines. When it is necessary to clean the heavy impurities deposited at the bottom of the tank, the pump is turned off and the drain valve is opened. The sludge is discharged from the drain pipe 27 by gravity or external flushing water.

[0048] Example 4 To allow operators to manually or automatically adjust the spacing between adjacent isolation bars 11 according to the width of the pulping tank 1 and the characteristics of the floating impurities, so as to adapt to the retrieval needs under different working conditions and optimize the retrieval efficiency, the bottom end of the vertical bar 12 is installed on a sliding seat, the sliding seat is installed on a slide rail, the slide rail is fixed to the bottom of the pulping tank 1, and the slide rail and the length direction of the isolation bar 11 are perpendicular.

[0049] To ensure that the isolation rod 11 always floats on the water surface, the isolation rod 11 is a hollow rod, and the outside of the isolation rod 11 is wrapped with a foam layer. The surface of the foam layer is wrapped with a smooth polytetrafluoroethylene sleeve made of a low coefficient of friction material, and a conical guide cap is set at the top of the rod to prevent plastic film or long fiber impurities from getting tangled on the rod, ensuring the long-term stable operation of the isolation rod; the vertical rod 12 includes a sleeve rod and a rod sleeve that are interlocked. The rod sleeve is fixed on the slide, and the sleeve rod is fixed on the outside of the isolation rod 11.

[0050] Example 5 An infrared photoelectric sensor array is installed inside the feed inlet 22 of the retrieval box 2 to detect the instantaneous flow rate of floating impurities entering the box. The controller adjusts the movement speed of the first linear moving structure 10 and the second linear moving structure 20 in real time according to the flow rate signal. When the impurity flow rate is large, such as exceeding 80% of the rated flow rate, the moving speed is automatically reduced, for example from 0.5 m / s to 0.3 m / s, to ensure sufficient collection; conversely, when the flow rate is small, the speed is appropriately increased to improve operating efficiency.

[0051] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
