Description

Technical Field

[0001] This invention relates to the field of waste paper treatment, specifically to an environmentally friendly treatment device for removing oil from oily waste paper and rendering it harmless. Background Technology

[0002] Waste paper is an important plant fiber raw material for the papermaking industry. Harmful substances in waste paper include mineral oil. To remove mineral oil from waste paper, existing technologies use chemical dewaxing agents to soak the waste paper in dewaxing water to achieve oil removal. However, this oil removal method carries the risk of creating a new environmental problem.

[0003] For example, patent application CN107119480B discloses a low-ink pulping method for waste paper recycling, including the following steps: 1) collecting waste paper and crushing it to obtain shredded paper; 2) subjecting the shredded paper to micro-fermentation treatment; 3) soaking and flotating the micro-fermented shredded paper to remove ink; 4) washing the sediment to remove impurities and then dewatering; 5) high-pressure cooking of the dewatered material to sterilization and softening; 6) squeezing, impregnation, and kneading the steam-softened material to homogenization treatment; 7) performing anti-fouling and fiber separation and re-decomposition; 8) purifying, concentrating, and storing for later use. This invention enables the use of recycled waste paper with excellent fiber quality for pulping, through two different micro-fermentation treatments before and after processing, and the synergistic effect of complementary subsequent processes, to achieve good ink removal results.

[0004] However, the existing technology of mechanically shredding waste paper is noisy, has low shredding efficiency, and often produces a lot of smoke and dust during the shredding process, resulting in a poor workshop environment. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly treatment device for the harmless treatment of oily waste paper, in order to solve the technical problems mentioned in the background art, such as high noise, smoke and dust affecting the workshop environment, and the risk of new environmental problems caused by chemical degreasing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An environmentally friendly treatment device for removing oil from waste paper includes a crushing mechanism and an oil removal tank. The crushing mechanism includes a crushing chamber with a water supply pipe connected to its side. The water supply pipe is connected to a crushing ring rotatably connected inside the crushing chamber. The inner side of the crushing ring has several water spray holes arranged in a ring array centered on the crushing ring's axis. Multiple crushing rings are arranged linearly along the crushing chamber's axis. The crushing ring is driven by a reciprocating motion mechanism. An oil suction float is installed inside the oil removal tank and is connected to an oil pump outside the tank. By using a crushing ring inside the crushing chamber with water spray holes, and simultaneously driving the crushing ring to the reciprocating motion mechanism, the water spray holes on the water spray ring can reciprocate. High-pressure water impacts the waste paper, crushing it. The crushed paper then enters the oil removal tank through the crushing chamber. The crushing process is low-noise and dust-free, purifying the workshop working environment.

[0008] Preferably, the reciprocating motion mechanism includes an arc-shaped rod fixedly connected to the crushing ring. The arc-shaped rod slides inside an arc-shaped cylinder, which is connected to a cylinder at the bottom of the crushing chamber. The reciprocating motion mechanism uses an arc-shaped rod and an arc-shaped cylinder in cooperation. The cylinder drives the arc-shaped rod to slide inside the arc-shaped cylinder. The stroke and return motion of the cylinder cause the arc-shaped rod to slide back and forth inside the arc-shaped cylinder, driving the crushing ring to rotate. This allows the water spray hole to rotate within a certain range, acting on different surfaces of the waste paper to achieve crushing.

[0009] Preferably, the sidewall of the crushing chamber is hollow, and the inner wall of the crushing chamber is provided with a through hole for connecting to the crushing ring. The arc-shaped cylinder is fixed to the inner side of the outer wall of the crushing chamber. The crushing ring includes an inner ring that fits against the inner side of the inner wall of the crushing chamber. The inner ring fits against the inner wall of the crushing chamber, and a plurality of annular array nozzles are fixed on the inner ring. The nozzles extend through the through hole in the inner wall of the crushing chamber to the hollow position of the sidewall of the crushing chamber. The part of the nozzle located in the hollow part of the crushing chamber is fixed by an outer ring. The outer ring fits against the outer side of the inner wall of the hollow part of the crushing chamber, and the arc-shaped rod is fixedly connected to the outer ring. The crushing ring is configured to connect multiple nozzles to the inner ring. The inner ring fits against the inner wall of the crushing chamber, so that the hollow part of the sidewall of the crushing chamber is relatively closed with the inside of the crushing chamber. In order to enhance the strength of the crushing ring and facilitate the connection of the arc-shaped rod, an outer ring is provided in the hollow part of the sidewall of the crushing chamber, and the outer ring fits against the outer side of the hollow inner wall of the crushing chamber. This improves the sealing performance, and the nozzles penetrate through the through hole to limit the extreme angle of rotation of the crushing ring.

[0010] Preferably, there are multiple crushing chambers arranged around the oil removal tank. The crushing chambers are connected to the oil removal tank. A baffle is provided at the connection between the crushing chamber and the oil removal tank. The side of the oil removal tank is connected to an adding cylinder, which contains an adding mechanism. The oil removal tank contains a collecting mechanism connected to a compression mechanism. The multiple crushing chambers are arranged on the circumference of the oil removal tank to achieve multi-directional crushing and feeding, thereby improving the efficiency of waste paper treatment. The oil pumping float can promptly discharge the floating oil in the oil removal tank.

[0011] Preferably, the baffle is disposed on the bottom side of the crushing chamber. The baffle includes multiple parallel, spaced, smooth guide rods. The bottom of the baffle is connected to a water source through a return water pipe. By discharging excess water used for crushing waste paper into the crushing chamber, the baffle is discharged back to the water source, thus saving water resources.

[0012] Preferably, the adding cylinder is fixed to the side of the crushing chamber and communicates with the oil removal tank through an adding pipe. A pressure plate is installed inside the adding cylinder, and the pressure plate is driven by a feeding mechanism via a pressure rod. The feeding mechanism includes a feeding wheel located on the side of the crushing chamber, and a tension spring is sleeved on the outside of the pressure rod. One end of the tension spring is fixed to the top of the adding cylinder, and the bottom end is fixed to the pressure plate. The pressure plate inside the adding cylinder is driven by the pressure rod to achieve a direct proportionality between the feeding and water addition, ensuring the water level in the oil removal tank and thus guaranteeing the oil removal efficiency. The oil pump float allows workers to remove floating oil by starting an oil pump when the liquid in the oil removal tank is still, and then turn off the oil pump after removal.

[0013] Preferably, the side section of the feeding wheel is arc-shaped, and the feeding wheel is coaxially and fixedly connected to the gear through the wheel axle. The gear meshes with the toothed plate fixed on the pressure rod. The side of the feeding wheel is provided with anti-slip texture. The feeding wheel is provided with anti-slip texture. By driving the feeding wheel to rotate, the waste paper enters the crushing chamber at a fixed quantity and speed, ensuring the degree of crushing.

[0014] Preferably, the oil pumping float is equipped with an oil pumping pipe that is softly connected to the high-pressure pipe and is connected to the oil pump. The oil pumping pipe is positioned above the solution in the oil removal tank so that the mineral oil floating above it can be pumped away.

[0015] Preferably, the collection mechanism includes a collection shaft disposed at the bottom of the oil removal tank. The collection shaft is hollow inside, and collection rods are fixedly connected to the side of the collection shaft. Several rows of collection rods are arranged in a circular array on the collection shaft with the axis of the collection shaft as the center. The collection rods are arc-shaped. A collection groove is provided on the side wall of the collection shaft between two rows of collection rods. A collection wheel is rotatably connected in the collection groove. The collection rods in the collection mechanism are arc-shaped. During the rotation of the collection rods, the collection rods come into contact with the crushed and de-oiled waste paper. The waste paper in the solution slides along the collection rods due to the resistance of the water flow, causing the waste paper to move closer to the connection between the collection rod and the collection shaft, thereby achieving centralized collection of waste paper. The waste paper that has moved closer is driven into the inside of the collection shaft by the rotating collection wheel and falls into the compression cylinder from the collection shaft.

[0016] Preferably, a compression mechanism is provided below the oil removal tank. The compression mechanism includes a compression cylinder. The bottom end of the collecting shaft passes through the oil removal tank and communicates with the compression cylinder. A compression plate is slidably connected inside the compression cylinder. A discharge port is provided at the other end of the compression cylinder. A sealing plate is rotatably connected to the discharge port. A drain hole is provided on the sealing plate. The compression plate is driven by a cylinder to slide inside the compression cylinder. After the compression plate compresses the waste paper in the compression cylinder, the compressed waste paper is discharged from the discharge port for reuse. During the compression process, wastewater is discharged from the drain hole on the sealing plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. A crushing ring is installed in the crushing chamber, and a ring array of water spray holes is installed on the crushing ring. The crushing ring is connected to a high-pressure water pump. The water sprayed from the water spray holes impacts the wastewater to achieve crushing. The process is low in noise and dust-free, improving the processing environment in the workshop.

[0019] 2. The crushing ring is connected to the reciprocating motion mechanism, which makes the water spray hole rotate back and forth continuously within a certain range. The sprayed water column impacts and enters different parts of the waste paper in the crushing chamber, achieving comprehensive crushing.

[0020] 3. Install a perforated plate inside the crushing chamber to drain excess crushing water and improve water resource utilization.

[0021] 4. The crushing chambers are set up in multiple ways and distributed around the circumference of the oil removal tank to achieve simultaneous feeding from multiple directions and the addition of water to replenish the water consumption in the oil removal tank.

[0022] 5. Waste paper is added using a feeding wheel to control the feeding rate, and the amount of water added is proportional to the amount of waste paper added to ensure the water level in the degreasing tank.

[0023] 6. The oil removal tank is equipped with an oil extraction pipe connected to the oil removal float to extract the floating mineral oil in the oil removal tank, extend the utilization cycle of the oil removal solution in the oil storage tank, reduce the amount of solution discharged, and ensure the oil removal effect without increasing new environmental risks.

[0033] Example 1

[0034] like Figure 1-4 As shown, an environmentally friendly treatment device for the degreasing and harmless treatment of oily waste paper includes a crushing mechanism 1 and an oil removal tank 2. The crushing mechanism 1 includes a crushing chamber 11, with a water supply pipe connected to the side of the crushing chamber 11. The water supply pipe is connected to a crushing ring 13 rotatably connected inside the crushing chamber 11. Several water spray holes are arranged in a ring array with the axis of the crushing ring 13 as the center on the inner side of the crushing ring 13. There are multiple crushing rings 13, and the multiple crushing rings 13 are arranged linearly with the axis of the crushing chamber 11 as the path. The crushing rings 13 are connected to a reciprocating motion mechanism 15. An oil pumping float is provided inside the oil removal tank (2), and the oil pumping float is connected to an oil pump outside the oil removal tank (2). The crushing mechanism 1 can be set as one or more as needed, and its position can be set on the top, side or other position of the oil removal tank 2.

[0035] When crushing waste paper, the waste paper is fed into the crushing chamber 11 from the top through an external conveying device. At the same time, the crushing ring 13, which is connected to the side wall of the crushing chamber 11 by the reciprocating motion mechanism 15, rotates around the axis of the crushing chamber 11. The hollow part of the side wall of the crushing chamber 11 is connected to a water source through a high-pressure water pump. The high-pressure water is sprayed into the crushing chamber 11 at high speed through the water spray hole and impacts the waste paper fed into it, causing the waste paper to be crushed. The crushed waste paper enters the oil removal tank 2 through the crushing chamber 11 for oil removal. After oil removal, it is filtered and compressed for reuse. During this process, the crushing ring 13 rotates back and forth at a certain angle in the crushing chamber 11 under the drive of the reciprocating motion mechanism 15, so that the water jet sprayed from the water spray hole can impact the waste paper from different sides, improving the degree of crushing. Since the waste paper is crushed by water flow impact, it has the advantages of low noise and no dust, and purifies the workshop environment.

[0036] Example 2

[0037] like Figure 1-4 As shown, an environmentally friendly treatment device for removing oil from waste paper includes a crushing mechanism 1 and an oil removal tank 2. The crushing mechanism 1 includes a crushing chamber 11, with a water supply pipe connected to the side of the crushing chamber 11. The water supply pipe is connected to a crushing ring 13 rotatably connected inside the crushing chamber 11. The inner side of the crushing ring 13 is provided with a plurality of water spray holes arranged in a ring array with the axis of the crushing ring 13 as the center. There are multiple crushing rings 13, and the multiple crushing rings 13 are arranged linearly with the axis of the crushing chamber 11 as the path. The crushing rings 13 are connected to a reciprocating motion mechanism 15. An oil pumping float is provided inside the oil removal tank (2), and the oil pumping float is connected to an oil pump outside the oil removal tank (2). The reciprocating motion mechanism 15 includes an arc-shaped rod 152 fixedly connected to the crushing ring 13. The arc-shaped rod 152 is connected to the arc-shaped rod 152 rotatably ... The arc-shaped cylinder 151 slides within the crushing chamber 11 and is connected to the cylinder 12 at the bottom of the crushing chamber 11. The side wall of the crushing chamber 11 is hollow, and the inner wall of the crushing chamber 11 is provided with a through hole connected to the crushing ring 13. The arc-shaped cylinder 151 is fixed to the inner side of the outer wall of the crushing chamber 11. The crushing ring 13 includes an inner ring 133 that fits against the inner side of the inner wall of the crushing chamber 11. The inner ring 133 fits against the inner wall of the crushing chamber 11. Several annular arrays of nozzles 132 are fixed on the inner ring 133. The nozzles 132 extend through the through hole in the inner wall of the crushing chamber 11 to the hollow position of the side wall of the crushing chamber 11. The part of the nozzle 132 located in the hollow part of the crushing chamber 11 is fixed by the outer ring 131. The outer ring 131 fits against the outer side of the inner wall of the hollow part of the crushing chamber 11. The arc-shaped rod 152 is fixedly connected to the outer ring 131.

[0038] The crushing ring 13 includes an inner ring 133 whose outer side is attached to the inner wall of the crushing chamber 11. Several nozzles 132 arranged in a ring around the inner ring 133 are fixedly connected to the inner ring 133, allowing the multiple nozzles 132 to act on the waste paper from various angles. Combined with the rotating crushing ring 13, this ensures that the water flow acts on the waste paper from all directions, achieving comprehensive crushing. Simultaneously, the outer ends of the multiple nozzles 132 are fixedly connected to an outer ring 131, the inner side of which is attached to the outer side of the hollow inner wall of the crushing chamber 11. That is, the inner ring 133 and the outer ring 131 are respectively attached to the two sides of the inner wall of the hollow sidewall of the crushing chamber 11, achieving closure in the middle of the crushing chamber 11. This also allows the crushing ring 13 to rotate relative to the inner ring 13. The outer ring 131 is fixedly connected to the arc-shaped rod 152, which slides inside the arc-shaped cylinder 151. The arc-shaped cylinder 151 is connected to the cylinder 12 fixed at the bottom of the crushing chamber 11. When the piston in the cylinder 12 moves, it compresses the gas in the cylinder 12 and causes it to enter the arc-shaped cylinder 151. The arc-shaped rod 152 slides outward relative to the arc-shaped cylinder 151 under pressure. When the piston in the cylinder 12 returns, the air pressure in the arc-shaped cylinder 151 decreases. Under the pressure difference, the arc-shaped rod 152 can enter the arc-shaped cylinder 151. The continuous stroke and return of the cylinder 12 can make the crushing ring 13 rotate continuously in the crushing chamber 11, thereby realizing the all-round crushing of waste paper.

[0039] Example 3

[0040] like Figure 1-4As shown, an environmentally friendly treatment device for removing oil from waste paper includes a crushing mechanism 1 and an oil removal tank 2. The crushing mechanism 1 includes a crushing chamber 11, with a water supply pipe connected to the side of the crushing chamber 11. The water supply pipe is connected to a crushing ring 13 rotatably connected inside the crushing chamber 11. The inner side of the crushing ring 13 is provided with a plurality of water spray holes arranged in a ring array with the axis of the crushing ring 13 as the center. There are multiple crushing rings 13, and the multiple crushing rings 13 are arranged linearly with the axis of the crushing chamber 11 as the path. The crushing rings 13 are connected to a reciprocating motion mechanism 15 for transmission. The oil removal tank (2) An oil pump float is installed inside the crushing chamber 11. The oil pump float is connected to an oil pump other than the oil tank (2). The reciprocating motion mechanism 15 includes an arc-shaped rod 152 fixedly connected to the crushing ring 13. The arc-shaped rod 152 slides inside the arc-shaped cylinder 151. The arc-shaped cylinder 151 is connected to the cylinder 12 at the bottom of the crushing chamber 11. The side wall of the crushing chamber 11 is hollow. The inner wall of the crushing chamber 11 is provided with a through hole connected to the crushing ring 13. The arc-shaped cylinder 151 is fixed to the inner side of the outer wall of the crushing chamber 11. The crushing ring 13 includes an inner ring 133 that fits against the inner side of the inner wall of the crushing chamber 11. The inner ring 133 is fitted to the inner wall of the crushing chamber 11. Several annular arrays of nozzles 132 are fixed to the inner ring 133. The nozzles 132 extend through through holes in the inner wall of the crushing chamber 11 to the hollow side wall of the crushing chamber 11. The hollow portion of the nozzles 132 is fixed by an outer ring 131, which is fitted to the outer side of the inner wall of the hollow portion of the crushing chamber 11. An arc-shaped rod 152 is fixedly connected to the outer ring 131. There are multiple crushing chambers 11, and these multiple crushing chambers 11 are arranged around the oil removal tank 2. The crushing chambers 11 and the oil removal tank... 2. A strainer 14 is provided at the connection between the crushing chamber 11 and the oil removal tank 2. The side of the oil removal tank 2 is connected to the adding cylinder 51. The adding cylinder 51 is provided with an adding mechanism 5. The oil removal tank 2 is provided with an oil pump float. The oil pump float is connected to an oil pump outside the oil removal tank 2. The oil removal tank 2 is provided with a collecting mechanism 4. The collecting mechanism 4 is connected to the compression mechanism 3. The strainer 14 is provided at the bottom of the crushing chamber 11. The strainer 14 includes multiple parallel and spaced smooth guide rods. The bottom of the strainer 14 is connected to the water source through a return water pipe 16.

[0041] An oil-sucking float (not shown in the figure) is placed inside the oil-sucking tank 2. The oil-sucking float has a hollow internal structure and is connected to an oil-sucking pipe, which in turn is connected to an oil pump. By connecting the oil-sucking pipe to the float, the oil-sucking float can always float above the oil-sucking solution, thus placing the end of the oil-sucking pipe above the oil-sucking solution. Based on the principle that mineral oil floats above the solution, most of the floating oil layer in the oil-sucking solution can be removed, thereby extending the service life of the oil-sucking solution, making full use of the water in the oil-sucking tank 2, and reducing the discharge of oil-sucking water. A strainer 14 is set on the bottom side of the crushing chamber 11. When the mixture of crushed waste paper and water passes through the strainer 14, the water can be filtered down on the strainer 14. Excess water flows back to the water source through the return water pipe 16 and is reused to crush waste paper, which can save water resources.

[0042] Example 4

[0043] like Figure 1-5 As shown, an environmentally friendly treatment device for removing oil from waste paper includes a crushing mechanism 1 and an oil removal tank 2. The crushing mechanism 1 includes a crushing chamber 11, with a water supply pipe connected to the side of the crushing chamber 11. The water supply pipe is connected to a crushing ring 13 rotatably connected inside the crushing chamber 11. Several water spray holes are arranged in a ring array with the axis of the crushing ring 13 as the center on the inner side of the crushing ring 13. There are multiple crushing rings 13, and the multiple crushing rings 13 are arranged linearly with the axis of the crushing chamber 11 as the path. The crushing rings 13 are connected to a reciprocating motion mechanism 15. An oil pumping float is provided inside the oil removal tank (2), and the oil pumping float is connected to an oil pump outside the oil removal tank (2). There are multiple crushing chambers 11, and the multiple crushing chambers 11 are arranged around the oil removal tank 2. The crushing chambers 11 are connected to the oil removal tank 2. A baffle plate 14 is provided at the connection between the crushing chamber 11 and the oil removal tank 2. The side of the oil removal tank 2 is connected to an adding cylinder 51. An adding cylinder 51 is provided inside the adding cylinder 51. The addition mechanism 5 includes an oil removal tank 2 with an oil pump float connected to an oil pump outside the oil removal tank 2. The oil removal tank 2 has a collection mechanism 4 connected to a compression mechanism 3. An addition cylinder 51 is fixed to the side of the crushing chamber 11 and is connected to the oil removal tank 2 via an addition pipe 56. A pressure plate 58 is installed inside the addition cylinder 51 and is connected to the feeding mechanism via a pressure rod 52. The feeding mechanism includes a feeding wheel 55 located on the side of the crushing chamber 11. A tension spring 57 is sleeved on the outside of the pressure rod 52. One end of the tension spring 57 is fixed to the top of the addition cylinder 51, and the bottom end is fixed to the pressure plate 58. The side section of the feeding wheel 55 is arc-shaped. The feeding wheel 55 is coaxially fixed to a gear 54 via a wheel axle 432. The gear 54 meshes with a toothed plate 53 fixed on the pressure rod 52. The side of the feeding wheel 55 has anti-slip texture 551.

[0044] When water is added, the feeding wheel 55 rotates under the drive of an external drive motor. Due to the anti-slip texture 551 on its surface, it can press the waste paper deep into the crushing chamber 11. At the same time, the feeding wheel 55 is fixedly connected to the gear 54, and the gear 54 meshes with the toothed plate 53. When the gear 54 rotates, it can drive the toothed plate 53 to move up and down. The magnetic plate is fixedly connected to the pressure rod 52, and the pressure rod 52 is fixedly connected to the pressure plate 58 that is slidably set in the adding cylinder 51. Therefore, the rotation of the feeding wheel 55 can cause the pressure plate 58 to move down, so that the water in the adding cylinder 51 is pressed into the oil removal tank 2 through the adding pipe 56. The rotation amount of the feeding wheel 55 is positively correlated with the feeding amount, and the rotation amount of the feeding wheel 55 is positively correlated with the downward movement of the pressure plate 58. Therefore, the feeding amount is positively correlated with the amount of water added in the adding cylinder 51, ensuring that the water level in the oil removal solution in the oil removal tank 2 is maintained within a certain range, thus playing a role in efficient oil removal.

[0045] Example 5

[0046] like Figure 1-8As shown, an environmentally friendly treatment device for removing oil from waste paper includes a crushing mechanism 1 and an oil removal tank 2. The crushing mechanism 1 includes a crushing chamber 11, with a water supply pipe connected to the side of the crushing chamber 11. The water supply pipe is connected to a crushing ring 13 rotatably connected inside the crushing chamber 11. Several water spray holes are arranged in a ring array with the axis of the crushing ring 13 as the center on the inner side of the crushing ring 13. There are multiple crushing rings 13, and the multiple crushing rings 13 are arranged linearly with the axis of the crushing chamber 11 as the path. The crushing rings 13 are connected to a reciprocating motion mechanism 15. An oil pumping float is provided inside the oil removal tank (2), and the oil pumping float is connected to an oil pump outside the oil removal tank (2). There are multiple crushing chambers 11, and the multiple crushing chambers 11 are arranged around the oil removal tank 2. The crushing chambers 11 are connected to the oil removal tank 2. A strainer 14 is provided at the connection between the crushing chamber 11 and the oil removal tank 2. The side of the oil removal tank 2 is connected to an adding cylinder 51. An adding mechanism 5 is provided inside the oil removal tank 2. An oil pumping float is provided inside the oil removal tank 2 and is connected to an oil pump outside the oil removal tank 2. A collecting mechanism 4 is provided inside the oil removal tank 2 and is connected to a compression mechanism 3. The collecting mechanism 4 includes a collecting shaft 41 located at the bottom of the oil removal tank 2. The collecting shaft 41 is hollow inside. A collecting rod 42 is fixedly connected to the side of the collecting shaft 41. The collecting rod 42 has several rows and is arranged in a ring around the axis of the collecting shaft 41. The collecting rod 42 is arc-shaped. A collecting groove is provided on the side wall of the collecting shaft 41 between two rows of collecting rods 42. A collecting wheel 43 is rotatably connected inside the collecting groove. The bottom end of the collecting shaft 41 passes through the oil removal tank 2 and is connected to the compression cylinder 31. A compression plate 32 is slidably connected inside the compression cylinder 31. A discharge port is provided at the other end of the compression cylinder 31. A sealing plate 33 is rotatably connected to the discharge port. A drain hole 331 is provided on the sealing plate 33. The compression cylinder 31 can be configured into a circular, rectangular, triangular or other shapes as required, so that the waste paper can meet the usage requirements after degreasing and compression.

[0047] An external motor (not shown in the figure) connected to the collecting rod 42 is mounted on the collecting shaft 41. Driven by the external motor, the collecting rod 42 rotates within the oil removal tank 2. Because the collecting rod 42 is arc-shaped, during its rotation, the degreased waste paper adhering to the inner side of the collecting rod 42 experiences resistance from the water flow. This resistance generates a tangential force along the collecting rod 42, allowing the waste paper to slide along the collecting rod 42 to the collecting shaft 41. The degreased waste paper accumulated on the side of the collecting shaft 41 is then collected by the collecting wheel 43, which rotates relative to the collecting shaft 41. The waste paper is carried into the space between the two wheel pieces 431 connected to the axle 432 of the collecting wheel 43, and enters the compression cylinder 31 through the hollow part inside the collecting wheel 43. After the collecting shaft 41 rotates for a certain period of time, when the waste paper accumulates in the compression cylinder 31 to a certain amount, the compression plate 32 is driven by the cylinder 12 to slide to the left relative to the compression cylinder 31, so that the waste paper is compressed. During the compression process, the water contained in the waste paper is discharged through the drain hole 331 on the sealing plate 33. After the compression is completed, the sealing plate 33 is opened, and the pulp that can be reused can be taken out for use in papermaking.
