Description

Technical Field

[0001] The present invention relates to the technical field of solid waste recycling and treatment, and specifically relates to a reuse system for confidential documents for economic management. Background Art

[0002] In today's information age, many office operations have been networked, but there are still a lot of confidential information recorded on paper documents for storage and viewing. When these paper documents are no longer needed, in order to reduce security risks such as information leakage, they need to be processed. The current common processing methods have deficiencies. For example, tearing the documents by hand, the size of the fragments may still allow the information to be pieced together and obtained; using a crushing device can crush the documents into smaller pieces, but it will cause the document debris to be too scattered and numerous, making subsequent recycling difficult. There are some existing processing devices, such as the patent with the publication number CN219211034U and the patent name of a highly confidential and green environmental protection document processing device. Although this patent can facilitate subsequent recycling by crushing the documents, adding water and kneading them into pulp, and then dehydrating and pressing them into blocks, the device is relatively large in size and not easy to carry. In many scenarios, such as when an economic research team goes out for investigation, a small enterprise manager goes out for business negotiation, an outdoor training or seminar activity organized by an economic management department, etc., the device needs to be convenient to carry to meet the need for timely document processing, and the existing devices cannot meet this well. Summary of the Invention

[0006] Preferably, the one-way locking component includes a triangular block and a first spring; a chute is provided on the upper end surface of the processing cylinder along the radial direction; the lower position of the triangular block is slidably connected in the chute; one side of the triangular block away from the center of the processing cylinder is connected to the chute wall by a first spring; a guiding surface is provided at one end of the triangular block close to the center of the processing cylinder and inclined upward.

[0007] Preferably, a knife groove is provided on the outer wall of the processing column; the cutter is slidably and sealingly connected in the knife groove; the cutter is connected to the bottom of the knife groove by a tension spring; the bottom of the knife groove is communicated with the upper end surface of the processing column through a knife hole.

[0008] Preferably, the spiral groove is composed of a spiral part at the upper position and a vertical part at the lower position; the lower end of the spiral part of the spiral groove is communicated with the upper end of the vertical part.

[0009] Preferably, an inner annular groove is provided on the inner wall of the activity ring; one end of the vertical block is movably connected in the inner annular groove, and the other end is slidably connected in the vertical groove; anti-slip protrusions are uniformly fixedly connected to the upper surface of the activity ring near the outer edge.

[0010] Preferably, the vertical part of the spiral groove is in a vertical corrugated shape; the processing column will rotate back and forth when the movable block moves along the vertical part.

During the process of the treatment column rotating forward and backward repeatedly, the mesh ring will be driven to rotate, and during the process of the mesh ring rotating forward and backward repeatedly, the pulp will be driven to be close to the lower surface of the movable ring, so as to realize the kneading and compaction of the pulp in the treatment cavity, and further make the pulp easier to aggregate into a mass, improving the treatment effect of solid waste.

Specific embodiments

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] As Figures 1 to 9 shown, the present invention includes the following embodiments:

[0030] Embodiment 1: A system for reusing confidential documents for economic management, comprising a processing cylinder 1 with an open upper end and a processing column 2 movably disposed inside the processing cylinder 1; a movable rod 3 is fixedly connected to the center of the inner bottom wall of the processing cylinder 1; an activity hole 21 for the movable rod 3 to insert and move is provided on the lower surface of the processing column 2; the bottom of the activity hole 21 and the upper end of the movable rod 3 are abutted by a second spring 22; a spiral groove 23 is provided on the inner wall of the activity hole 21; a movable block 31 is movably connected in the spiral groove 23; the movable block 31 is fixedly connected to the outer wall of the movable rod 3; a net ring 4 is fixedly connected to the lower position of the outer wall of the processing column 2; a movable ring 5 is movably sleeved on the outer wall of the processing column 2 in a sealing manner; the outer edge of the movable ring 5 is in movable sealing cooperation with the inner wall of the processing cylinder 1; a vertical groove 24 is provided on the outer wall of the processing column 2; a vertical block 25 is slidably and sealingly connected up and down in the vertical groove 24; the vertical block 25 is connected to the inner edge of the movable ring 5; a elastic cord 26 is connected between the upper surface of the vertical block 25 and the upper end of the vertical groove 24; a cutter 6 is provided on the outer wall of the processing column 2 and between the movable ring 5 and the net ring 4; the cutter 6 is disposed close to the upper surface of the net ring 4; a one-way locking assembly 7 for one-way locking of the movable ring 5 and the net ring 4 is provided on the upper end surface of the processing cylinder 1.

[0031] In this embodiment, a step groove 11 is recessed downward on the inner bottom wall of the processing cylinder 1; a socket 12 is provided on the inner wall of the step groove 11 along the radial direction of the processing cylinder 1; a plug rod 13 is movably and sealingly connected in the socket 12; a circular slot 27 is provided on the outer wall of the processing column 2 at a lower position; the slot 27 is located below the net ring 4; the plug rod 13 can be inserted into the slot 27.

[0032] In this embodiment, the one-way locking assembly 7 includes a triangular block 71 and a first spring 72; a chute 14 is provided on the upper end surface of the processing cylinder 1 along the radial direction; the lower position of the triangular block 71 is slidably connected in the chute 14; the side of the triangular block 71 away from the center of the processing cylinder 1 is connected to the groove wall of the chute 14 by a first spring 72; a guiding surface 73 is provided on the end of the triangular block 71 close to the center of the processing cylinder 1 and inclined upward.

[0033] During the process of carrying the processing cylinder 1, the processing column 2, the movable ring 5 and the mesh ring 4 are all located inside the processing cylinder 1 and have a small volume. If it is necessary to use the processing cylinder 1 to process confidential documents, the processing cylinder 1 will be placed on a flat tabletop. Subsequently, the insertion rod 13 is pulled out. The insertion rod 13 will move along the insertion hole 12 and be pulled out from the annular slot 27, unlocking the processing cylinder 1. The second spring 22 will drive the processing column 2 to move upward. During the upward movement of the processing column 2, the mesh ring 4 will be driven to move upward. The movable ring 5 is stuck below the triangular block 71. The upward movement of the processing column 2 will cause the vertical block 25 to slide in the vertical groove 24. Both the mesh ring 4 and the movable ring 5 will be stuck below the triangular block 71. Subsequently, the triangular block 71 is toggled away from the center of the processing cylinder 1. The lower end of the triangular block 71 will overcome the first spring 72 and slide along the chute 14. The triangular block 71 will move away from the upper surface of the movable ring 5, unlocking the movable ring 5. The elastic cord 26 will pull the vertical block 25 to move in the vertical groove 24. The vertical block 25 will drive the movable ring 5 to move upward along the outer wall of the processing column 2, causing the space between the movable ring 5 and the mesh ring 4 to increase during the upward movement of the movable ring 5. A processing cavity is formed between the movable ring 5 and the mesh ring 4; a storage cavity is formed between the lower surface of the mesh ring 4 and the inner bottom wall of the processing cylinder 1; pour water along the upper surface of the mesh ring 4, and the water will pass through the mesh ring 4 and flow into the storage cavity; then press the processing column 2 downward while putting the confidential document into the processing cavity. During the slow downward movement of the processing column 2, the cutter 6 on the outer wall will rotate synchronously with the processing column 2. The processing cavity will rotate as the processing column 2 rotates. When the position of the processing cavity changes, it can prevent the same position from continuously putting confidential documents and causing accumulation, making the confidential documents, that is, waste paper, more evenly distributed in the processing cavity. The mesh ring 4 will move downward as the processing column 2 moves downward. During the downward movement of the mesh ring 4, the water in the storage cavity will be squeezed, and the water will enter the processing cavity through the holes on the mesh ring 4, making the paper in the processing cavity wet. The wet paper is easier to shred during the rotation of the cutter 6. As the processing column 2 continues to move downward, the processing column 2 will drive the movable ring 5 into the inside of the processing cylinder 1. During the downward movement of the movable ring 5, it will contact and press the guiding surface 73, causing the triangular block 71 to be pressed and slide along the chute 14 away from the center of the processing cylinder 1 against the first spring 72. Until the movable ring 5 moves downward past the triangular block 71, the triangular block 71 will slide along the chute 14 close to the center of the processing cylinder 1 under the elastic force of the first spring 72. The triangular block 71 will move to the upper surface of the movable ring 5 and restrict the upward movement of the movable ring 5. After the movable ring 5 enters the inside of the processing cylinder 1, it will seal the upper port of the processing cylinder 1. Subsequently, intermittently press the processing column 2. When the processing column 2 is released, the second spring 22 will push the processing column 2 upward. During the upward movement of the processing column 2, the spiral groove 23 and the spiral block will move. Under the spiral guidance of the spiral groove 23, the processing column 2 will rotate. During the rotation of the processing column 2, the cutter 6 will rotate. The rotating cutter 6 will crush the solid waste in the processing cavity. The upward movement of the processing column 2 will cause the mesh ring 4 to move upward.The space in the processing chamber becomes smaller, while the space in the storage chamber becomes larger. The excess water in the processing chamber will flow through the holes on the mesh ring 4 into the storage chamber. As the space in the processing chamber becomes smaller, the solid waste becomes more concentrated, enabling crushing in a smaller space and improving the crushing efficiency. After the processing column 2 reaches its upper limit position, pressing the processing column 2 again will cause the processing column 2 to move downward, driving the cutter 6 to rotate. Since the water in the processing chamber is not full, when the processing column 2 moves downward, the water in the processing chamber will be sprayed into the processing chamber along the mesh ring 4, enabling the solid waste in the processing chamber to be crushed in a submerged state. After the processing column 2 moves up and down repeatedly, the solid waste is turned into utilizable pulp. As the processing column 2 moves upward for the last time, the processing column 2 will drive the mesh ring 4 to move upward and approach the movable ring 5. The pulp in the processing chamber will gather at the outer edge position of the mesh ring 4 under the action of centrifugal force. As the processing column 2 moves upward, the pulp on the mesh ring 4 driven by the processing column 2 will come into contact with the lower surface of the movable ring 5. Under the extrusion of the lower surface of the movable ring 5 and the upper surface of the mesh ring 4, the excess water remaining in the pulp will flow out along the holes on the mesh ring 4. To ensure the forming effect of the pulp, the processing column 2 can also be intermittently pressed a small distance repeatedly. When the processing column 2 moves downward while keeping the mesh ring 4 not in contact with the water level in the storage chamber, release the pressing of the processing column 2 after it moves downward a small distance, and then the processing column 2 moves upward again to control the pulp to be extruded by the movable ring 5 and the mesh ring 4, enabling the pulp to be extruded and formed again. Finally, move the triangular block 71 away from the center of the processing cylinder 1. The triangular block 71 will move along the chute 14 and overcome the first spring 72, and the triangular block 71 will move away from the upper surface of the movable ring 5, unlocking the movable ring 5. The elastic cord 26 will pull the vertical block 25 to slide in the vertical groove 24 and drive the movable ring 5 to move upward, exposing the processing chamber. Finally, take out the compacted pulp in the processing chamber to complete the treatment of the solid waste, turning waste into treasure. The compacted pulp is convenient for subsequent recycling. After completing the treatment of solid waste such as confidential documents, invert the processing cylinder 1. When the processing cylinder 1 has its opening facing downward, the water in the storage chamber will flow out. After the lower end of the processing column 2 enters the stepped groove 11, it will push the insertion rod 13 to insert into the slot 27 along the insertion hole 12, realizing the locking after the folding of the processing column 2, making the volume of the processing cylinder 1 and the processing column 2 smaller and more convenient to carry.

[0034] In the present invention, the processing column 2 moves up and down along the inner side of the processing cylinder 1, enabling solid waste such as confidential documents to be crushed into dehydrated and compacted pulp, thus facilitating the recycling of solid waste. Compared with the prior art, the present invention is characterized by being small and convenient to carry.

[0035] Since the present invention can be used without electricity and is light and portable, the demand for such devices is more prominent in the field of economic management. For example, when an economic research team conducts investigations in remote areas, they often face power shortages. However, the paper documents containing business secrets or sensitive data they carry need to be processed in a timely manner, and small, non-electric devices can just meet this need. When managers of small enterprises go out to negotiate business, if they need to destroy relevant documents on the way or at a temporary negotiation point (where power supply is insufficient), this device is convenient and practical. In addition, for outdoor training or seminar activities organized by economic management departments, where the venue is temporary and the power supply is unstable, this device can ensure the safe and convenient processing of documents, enabling personnel to focus on their work.

[0036] Embodiment 2: A knife groove 28 is provided on the outer wall of the processing column 2; the cutting knife 6 is slidably and sealingly connected in the knife groove 28; the cutting knife 6 is connected to the bottom of the knife groove 28 through a tension spring 61; the bottom of the knife groove 28 communicates with the upper end face of the processing column 2 through a knife hole 29.

[0037] In this embodiment, the spiral groove 23 is composed of a spiral part 231 at the upper position and a vertical part 232 at the lower position; the lower end of the spiral part 231 of the spiral groove 23 communicates with the upper end of the vertical part 232.

[0038] During the downward movement of the processing column 2 under pressure, the processing column 2 will drive the movable hole 21 and the movable rod 3 to move. The movable block 31 on the outer wall of the movable rod 3 will enter the spiral part 231 along the vertical part 232 of the spiral groove 23, so that the processing column 2 will rotate. During the rotation of the processing column 2, the cutting knife 6 will be driven to rotate. When the cutting knife 6 rotates with the processing column 2, a centrifugal force is generated, so that the cutting knife 6 overcomes the tension spring 61 under the action of the centrifugal force and moves away from the bottom of the knife groove 28. In this way, the cutting knife 6 will extend out of the knife groove 28 and enter the processing cavity. The outside gas will enter the knife groove 28 along the knife hole 29 for gas replenishment. Both edges of the cutting knife 6 have cutting surfaces, so that the cutting surface of the cutting knife 6 breaks the solid waste in the processing cavity. After the processing column 2 reaches the lower limit position, reduce the force pressing the processing column 2, and the second spring 22 will push the processing column 2 to move upward, so that the movable block 31 will move along the spiral part 231 of the spiral groove 23 again. The processing column 2 will drive the cutting knife 6 to rotate in the reverse direction to generate a centrifugal force again, so that the cutting knife 6 remains in the state of extending out of the knife groove 28. The processing column 2 will move up and down within the range where the movable block 31 moves along the spiral part 231 of the spiral groove 23. In this way, the processing column 2 will drive the cutting knife 6 to rotate to generate a centrifugal force, ensuring that the cutting knife 6 extends out of the knife groove 28. After the waste paper in the processing cavity is converted into pulp, it is necessary to compact the pulp. Specifically, it is necessary to control the net ring 4 to be close to the movable ring 5. The processing column 2 will move upward under the push of the second spring 22. During the upward movement of the processing column 2, the net ring 4 will be driven to move upward. The movable ring 5 is restricted below the triangular block 71. As the net ring 4 moves upward, the space of the processing cavity will become smaller. The movable block 31 will enter the vertical part 232 along the spiral part 231 of the spiral groove 23. During the movement of the movable block 31 along the vertical part 232, the processing column 2 will not rotate. In this way, the centrifugal force of the cutting knife 6 will drop instantly, so that the tension spring 61 pulls the cutting knife 6 back into the knife groove 28, and the waste debris on the surface of the cutting knife 6 is scraped off by the notch of the knife groove 28. After the cutting knife 6 moves out from between the movable ring 5 and the net ring 4, it avoids the cutting knife 6 affecting the mutual approach of the movable ring 5 and the net ring 4, so that the pulp in the processing cavity is pressed more tightly, and the treatment effect of the solid waste is improved.

[0039] Embodiment 3: An inner annular groove 51 is provided on the inner wall of the movable ring 5; one end of the vertical block 25 is movably connected in the inner annular groove 51, and the other end is slidably connected in the vertical groove 24; anti-slip protrusions 52 are uniformly fixed on the upper surface of the movable ring 5 near the outer edge.

[0040] In this embodiment, the vertical part 232 of the spiral groove 23 is in a vertical corrugated shape; when the movable block 31 moves along the vertical part 232, the processing column 2 will rotate back and forth.

[0041] During the process of the downward movement of the processing column 2 driving the movable ring 5 into the inner side of the processing cylinder 1, the movable ring 5 will push open the triangular block 71 in the one-way locking assembly 7. Until the movable ring 5 enters the inner side of the processing cylinder 1, the triangular block 71 in the one-way locking assembly 7 will cover the upper surface of the movable ring 5 again. The movable ring 5 is always pressed against the lower surface of the triangular block 71 under the pulling of the elastic cord 26. As the movable block 31 rotates along the spiral part 231 in the spiral groove 23, the processing column 2 will drive the net ring 4 to rotate. During the rotation of the processing column 2, the vertical block 25 will be driven to rotate. During the rotation of the vertical block 25, it will move along the inner annular groove 51. The movable ring 5 abuts against the lower surface of the triangular block 71. Since the anti-slip protrusions 52 are stuck on both sides of the triangular block 71, the movable ring 5 will not rotate with the rotation of the vertical block 25, so that the movable ring 5 and the triangular block 71 remain stationary, avoiding friction and wear caused by their movement, and improving the service life of the movable ring 5; and in the case where the pulp needs to be compacted, the movable block 31 will enter the vertical part 232 of the spiral groove 23. Since the shape of the vertical part 232 is vertically corrugated, when the movable block 31 moves along the vertical part 232, the processing column 2 will rotate forward and reverse back and forth, but with a small rotation amplitude, it is difficult for the cutting knife 6 to extend out of the knife groove 28 under the action of centrifugal force. During the process of the processing column 2 rotating forward and reverse repeatedly, it will drive the net ring 4 to rotate. During the repeated forward and reverse rotation of the net ring 4, it will drive the pulp to be close to the lower surface of the movable ring 5, so as to realize the kneading and compaction of the pulp in the processing cavity, and further make the pulp easier to aggregate into a ball, improving the treatment effect on solid waste; in order to further improve the effect of kneading the pulp into a ball, the lower surface of the movable ring 5 can be roughened; in this embodiment, the fluctuation amplitude of the corrugation of the vertical part 232 is processed according to actual needs.

[0042] Embodiment 4: The movable rod 3 is movably and hermetically connected to the movable hole 21; the upper end of the movable hole 21 is communicated with the lower surface of the processing column 2 through a one-way liquid inlet hole 211; the upper end of the movable hole 21 is communicated with the arc-shaped outer wall of the processing column 2 through a one-way liquid outlet hole 212; the liquid outlet position of the one-way liquid outlet hole 212 is close to the upper surface of the net ring 4.

[0043] During the stage of crushing the waste paper in the processing chamber and forming pulp, the lower end of the processing column 2 will enter the position below the water surface in the storage chamber. In this way, when the processing column 2 moves up again, the water in the storage chamber can enter the movable hole 21 along the one-way liquid inlet hole 211 under the action of negative pressure. After the processing column 2 moves up and leaves the water surface in the storage chamber, the one-way liquid inlet hole 211 will suck the gas in the storage chamber, so that the gas enters the movable hole 21 along the one-way liquid inlet hole 211. As the processing column 2 moves down again, the gas and water in the movable hole 21 will be ejected along the one-way liquid outlet hole 212, and the liquid ejected from the one-way liquid outlet hole 212 will be ejected. The waste paper is wetted to improve the efficiency of soaking the waste paper; and in the stage of compacting the pulp in the processing chamber, the lower end of the processing column 2 moves up and down in a state higher than the water surface in the storage chamber, so that the one-way liquid outlet 212 sprays gas, and the gas will gather the pulp toward the outer edge of the mesh ring 4, thereby improving the agglomeration effect of the pulp and preventing the pulp from being too dispersed and difficult to compact into shape. In addition, since the gas enters the processing chamber, the gas pressure in the processing chamber will increase, so that the gas in the processing chamber drives the excess liquid on the pulp to pass through the mesh ring 4 into the storage chamber faster, thereby improving the dehydration effect of the pulp and further improving the treatment effect of solid waste.

[0044] Example 5: The center of the upper surface of the processing column 2 is rotatably connected to the pressing block 8; the lower surface of the processing cylinder 1 is fixedly connected to the rubber pad 15.

[0045] Since the processing chamber is pressed by the pressing block 8, the contact friction between the upper end of the processing column 2 and the operator's hand is reduced, making the processing column 2 rotate more smoothly. In addition, the rubber pad 15 provided on the lower surface of the processing cylinder 1 makes the placement of the processing cylinder 1 more stable. The waste in the vertical groove 24 will be gathered at the lower end of the vertical groove 24 under the squeezing and pushing of the vertical block 25. Finally, the accumulated waste in the vertical groove 24 can be thrown out due to the centrifugal force generated by the rotation of the processing column 2, thereby ensuring the cleanliness of the vertical groove 24.
