Description

Technical Field

[0001] This invention relates to the field of separation and filtration technology, specifically to a pulp residue water separation and recovery device for the clean production of sterile toilet paper. Background Technology

[0002] In the pulping process of aseptic toilet paper, pulping, slag washing, screening, and thickening are usually carried out by chemical or mechanical methods. These processes also produce dilute and concentrated white water, which usually need to be separated and recycled. Some of this wastewater is directly mixed and reused, while some is filtered in a white water filter. The remaining dilute white water is fed into the pulp after adding a softener. However, existing methods for separating wastewater from raw pulp in aseptic toilet paper production make it difficult to clean the filter elements used in the separation device. The raw pulp itself also tends to adhere to the filter elements, which gradually reduces the subsequent filtration and separation effect, making it difficult to effectively and continuously separate and recycle wastewater. Therefore, this application proposes a raw pulp wastewater separation and recycling device for clean production of aseptic toilet paper to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a pulp residue water separation and recycling device for the clean production of sterile toilet paper, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: a pulp residue and water separation and recovery device for sterile toilet paper production, comprising a pulp residue and water holding container composed of a flat plate, a side square shell, and a flow holding shell, and a conveying platform. The side square shell and the flow holding shell are welded together, and both the side square shell and the flow holding shell are fixed to the flat plate with screws. A partition is fixedly provided on the flow holding shell, and an inner air guide column is fixedly inserted inside the partition. A main support plate is fixed on the top of the flat plate, and a rotating motor is fixed on the main support plate. The output shaft of the rotating motor is fixed to a passive rotating column through a coupling, and the passive rotating column is sleeved outside the inner air guide column. The passive rotating column is provided with several pulp adsorption discs, each... Each of the original pulp adsorption discs comprises a flow guide plate, a flow arc ring, an air guide fixing ring, and several fan-shaped pulp filters. The flow guide plate, flow arc ring, and air guide fixing ring are all sleeved on the outside of the inner air guide column. A bent guide tube is fixed on one side of the flow guide plate. The flow guide plate has several water-air universal holes, and each water-air universal hole is connected to the corresponding bent guide tube. Each fan-shaped pulp filter has inclined scrapers on both sides for scraping slag. A filter promoter is also provided on the top of the plate. An air inlet pipe is installed on one side of the inner air guide column. A fixing ring plate is connected to the outer wall of one side of the partition principle passive rotating column by screws. A water guide pipe is inserted into the bottom of the fixing ring plate.

[0005] Preferably, the fan-shaped slurry filter includes an inner cavity filter plate, a filter bag, a pluggable connecting pipe, and fixing strips. One end of the bent conduit is inserted into the passive rotating column, and the pluggable connecting pipe is connected to the bent conduit. The inner cavity filter plate is fixed to one side of the outer wall of the pluggable connecting pipe. The filter bag is sleeved on the outside of the inner cavity filter plate and fixed by the fixing strips at the top. Each pair of adjacent fixing strips can engage, so that several fan-shaped slurry filters can form a disc shape with the guide plate as the center.

[0006] Preferably, the highest point of the inclined scraper is in contact with the outer wall of the filter bag, the two inclined scrapers at the outermost edge are directly fixed to the side square shell, and the remaining inclined scrapers are fixed to the side square shell through side isolation support plates. An arc plate is welded between the two side isolation support plates on both sides of the same raw pulp adsorption plate, and the arc plate is integrally formed at the bottom of the flow-holding shell. The two side isolation support plates between two adjacent raw pulp adsorption plates are welded with fixed support plates, and the connecting space formed by the fixed support plate, the two side isolation support plates connected to it, and one side wall of the side square shell is located directly above the conveying platform, so that the scraped pulp residue can flow into the conveying platform.

[0007] Preferably, the flow-through arc ring and the air-guiding fixing ring are both fixedly sleeved on the outer peripheral wall of the inner air-guiding column. The outer peripheral of the flow-through arc ring is provided with a partial water-passing groove. The flow-through arc ring is also provided with an air passage hole and several connecting holes II. The air passage hole is located inside the connecting holes II.

[0008] Preferably, the flow guide plate is sleeved on the outer peripheral wall of the inner air guide column and can rotate around the inner air guide column. The flow guide plate is also provided with several connecting holes. When the flow guide plate rotates, the connecting holes can still be connected to the connecting holes, so that the slurry discharged from the bent guide tube can enter the fixed ring plate and be discharged from the water guide pipe. The air guide fixed ring is provided with a ventilation groove, and the outer peripheral wall of the inner air guide column is provided with several air inlets. Each ventilation groove can connect the corresponding air passage and air inlet.

[0009] Preferably, the filter includes a bidirectional rotating column, a limiting column, and several extrusion mechanisms.

[0012] This invention provides an improved pulp residue water separation and recovery device for the clean production of aseptic toilet paper, which has the following improvements and advantages compared with the prior art: Firstly, the present invention uses a pulp adsorption plate to continuously separate and recycle pulp residue from the pulp tank, allowing the pulp residue to be completely separated from the pulp and discharged separately. The pulp residue is completely separated from the pulp by compression filtration, then concentrated and guided, and the pulp residue is stably attached to the filter bag. The pulp residue is then completely scraped off by a subsequently inclined scraper, realizing the separation and recycling of pulp residue and pulp residue, which is beneficial to the clean production of sterile toilet paper. Secondly, after the raw pulp is separated into slurry and water, the compacted pulp residue and filter bags are expanded by introducing air individually. This reduces the adsorption force before the pulp residue is separated, making it easier for the pulp residue to fall off the filter bags. Combined with the scraper contacting the bulging filter bags, the pulp residue can be completely separated from the filter bags and guided into the conveying device, achieving a highly efficient and automated pulp residue separation and recycling effect.

[0013] Thirdly, the assembly of several fan-shaped filter elements with individual installation and disassembly facilitates subsequent maintenance and filter bag replacement and cleaning. The disassembly method is simple, which makes it easy for staff to carry out targeted inspection and cleaning work, eliminating the problems of traditional filtration devices being difficult to clean and install.

[0016] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides a pulp residue water separation and recovery device for sterile toilet paper production. The technical solution of this invention is as follows: Reference Figures 1-12As shown, a pulp residue and water separation and recycling device for sterile toilet paper production includes a pulp residue and water holding container consisting of a flat plate 1, a side square shell 6, and a flow holding shell 13, and a conveying platform 8. The side square shell 6 and the flow holding shell 13 are welded together and both are fixed to the flat plate 1 with screws. A partition 22 is fixedly provided on the flow holding shell 13, and an inner air guide column 12 is fixedly inserted inside the partition 22. A main support plate 9 is fixedly provided on the top of the flat plate 1, and a rotating electric motor is fixed on the main support plate 9. Machine 10, the output shaft of the rotating motor 10 is fixed to the driven rotating column 19 via a coupling, and the driven rotating column 19 is sleeved on the outside of the inner air guide column 12. The driven rotating column 19 is provided with several raw slurry adsorption discs. Each raw slurry adsorption disc consists of a flow guide plate 20, a flow arc ring 31, an air guide fixing ring 21 and several fan-shaped slurry filters. The flow guide plate 20, the flow arc ring 31 and the air guide fixing ring 21 are all sleeved on the outside of the inner air guide column 12. A bent guide tube 18 is fixed on one side of the flow guide plate 20. The guide plate 20 has several water-air universal holes 200, and each water-air universal hole 200 is connected to the corresponding bent conduit 18. Each fan-shaped filter has inclined scrapers 27 on both sides for scraping slag. The top of the plate 1 is also equipped with a filter promoter. An air inlet pipe 14 is installed on one side of the inner air column 12. The outer wall of the partition plate 22 is connected to the passive rotating column 19 by screws to a fixing ring plate 23. A water guide pipe 15 is inserted into the bottom of the fixing ring plate 23. The fan-shaped filter includes an inner cavity filter plate 1. 6. Filter bag 5, plug-in connecting pipe 17 and fixing strip 51, one end of the bent guide tube 18 is inserted into the passive rotating column 19, the plug-in connecting pipe 17 is connected to the bent guide tube 18, the inner cavity filter plate 16 is fixed to one side of the outer wall of the plug-in connecting pipe 17, the filter bag 5 is sleeved on the outside of the inner cavity filter plate 16 and fixed by the fixing strip 51 at the top, and each two adjacent fixing strips 51 can be engaged so that several fan blade filters can form a disc shape with the guide plate 20 as the center.

[0018] Regarding the pulp adhesion plate, it's important to understand that after the aseptic toilet paper pulp is added with filler and stirred, the pulp, along with water-insoluble solid impurities and particles, easily adhere to the upright filter bag 5. The PTFE filter bag used in this embodiment has high corrosion resistance and high-temperature stability. Combined with the compression of the bag by the compression mechanism, it allows the toilet paper pulp to adhere to the filter bag 5 and move with it. Furthermore, the filter bag 5 in the fan-shaped pulp filter is made of a double-opening, wider-than-narrower filter bag material. During installation, it should be installed according to… The shape of the fan blades starts from the bottom plug-in connecting tube 17 and slides onto the top of the inner cavity filter plate 16. The plug-in connecting tube 17 with the filter cloth bag 5 is inserted and fixed onto the bent guide tube 18. Finally, the removed fixing strip 51 is engaged with the adjacent fixing strip 51 to form a complete raw pulp adsorption plate. The engagement between the fixing strips 51 is only used to further strengthen and compact the bottom plug-in connecting tube 17 and the bent guide tube 18. The engagement method can be, but is not limited to, mutual plugging and unplugging.

[0019] Further clarification regarding the fan-shaped slurry filter is that a single fan-shaped slurry filter can be removed and installed via the plug-in structure between the plug-in connecting pipe 17 and the bent conduit 18, facilitating subsequent cleaning of the plug-in connecting pipe 17 and the bent conduit 18. For details on one possible movable connection method between the plug-in connecting pipe 17 and the bent conduit 18, please refer to [reference needed]. Figure 6 As shown, the plug-in connector 17 and the bent guide tube 18 are connected by a mortise and tenon structure. The plug-in connector 17 is inserted into the bent guide tube 18 and rotated to fix it, so that the entire fan-shaped pulp filter is put into the attachment work. The inner cavity type filter plate 16 is a hollow filter plate wrapped by the filter cloth bag 5. When the filter cloth bag 5 is squeezed, the water in the pulp adhering to its outer side is forced to the inner side and flows into the plug-in connector 17 through the inner hollow space of the inner cavity type filter plate 16. Furthermore, the water separated from the pulp eventually enters the water-air universal orifice 200 through the bent conduit 18. Initially, the flow arc ring 31, which does not have a local water channel 312, will close the water-air universal orifice 200. As the guide plate 20 rotates, the water-air universal orifice 200 will connect with the local water channel 312 in sequence. The water-air universal orifice 200 is in a flow state, guiding the pulp water at the top into the passive rotating column 19. Under the connection of the connecting hole 1 201 and the connecting hole 2 311, the pulp water will eventually pass through the partition 22 into the fixed ring plate 23 and finally be discharged from the water guide pipe 15.

[0020] Specifically, the highest point of the inclined scraper 27 is in contact with the outer wall of the filter bag 5. The two inclined scrapers 27 at the outermost edge are directly fixed to the side square shell 6. The remaining inclined scrapers 27 are fixed to the side square shell 6 through the side isolation support plate 33. An arc plate 29 is welded between the two side isolation support plates 33 on both sides of the same raw slurry adsorption plate. The arc plate 29 is integrally formed on the bottom of the flow-holding shell 13. The two side isolation support plates 33 between two adjacent raw slurry adsorption plates are welded with a fixed support plate 32. The connecting space formed by the fixed support plate 32, the two side isolation support plates 33 connected to it, and one side wall of the side square shell 6 is located directly above the conveying platform 8, so that the scraped slurry can flow into the conveying platform 8.

[0021] The oblique scraper 27, when applied to the pulp residue, guides the pulp residue as it falls into the connected space formed by the fixed support plate 32, the two side isolation support plates 33 connected to it, and one side wall of the side square shell 6, and then falls onto the conveying platform 8. The conveying platform 8 is a conventional electric conveying device, and in this application, it is only provided to convey sterile toilet paper pulp residue to the next production process.

[0022] Specifically, the flow-through arc ring 31 and the air-guiding fixing ring 21 are both fixedly sleeved on the outer peripheral wall of the inner air-guiding column 12. The outer periphery of the flow-through arc ring 31 is provided with a partial water-passing groove 312. The flow-through arc ring 31 is also provided with an air passage hole 310 and several connecting holes 311. The air passage hole 310 is located inside the connecting holes 311. The flow-guiding plate 20 is sleeved on the outer peripheral wall of the inner air-guiding column 12 and can rotate around the inner air-guiding column 12. The flow-guiding plate 20 is also provided with several One connecting hole 201, when the guide plate 20 rotates, the other connecting hole 311 can still maintain communication with the first connecting hole 201, so that the slurry discharged from the bent guide tube 18 can enter the fixed ring plate 23 and be discharged from the water guide tube 15. The air guide fixed ring 21 is provided with an air groove 210, and the outer peripheral wall of the inner air guide column 12 is provided with several air inlets 120. Each air groove 210 can connect the corresponding air flow hole 310 and air inlet 120.

[0023] The following explanation further clarifies the configuration and function of the air inlet pipe 14: The air inlet pipe 14 is used to continuously ventilate and maintain the high pressure state of the inner air guide column 12. After the slurry adsorption plate passes through the filter press to remove the slurry water, the slurry residue still adheres to the surface of the filter bag 5. Before rotating to the inclined scraper 27, the guide plate 20 passes through the air passage 310, and at this time, it connects to the inner air guide column 12 through the air passage 210 and the air inlet 120. At this point, the gas introduced through the air inlet pipe 14 can be guided into the connected bent conduit 18. The compacted pulp residue inside the filter bag 5 reduces the air permeability of the bag. When gas is introduced into the bag, it bulges out, making it easier for the pulp residue to be pushed off, reducing its adhesion to the filter bag 5. When the raw pulp adheres to the inclined scraper 27, the bulging filter bag 5 is more easily scraped off, allowing the pulp residue to be completely scraped to the bottom, achieving complete separation of raw pulp residue and water. The air passage 310 is designed to ensure that some of the pulp residue that falls off the expanded filter bag 5 can enter the conveying platform 8.

[0024] Specifically, the filter includes a bidirectional rotating column 28, a limiting column 34, and several extrusion mechanisms. Two support side plates 2 are fixedly installed on the plate 1. A bidirectional motor 24 is fixedly installed on one side of one of the support side plates 2. The bidirectional rotating column 28 is fixed to the output shaft of the bidirectional motor 24 through a coupling. The bidirectional rotating column 28 is rotatably connected between the two support side plates 2. The bidirectional rotating column 28 is provided with a bidirectional thread 281. The limiting column 34 is fixedly installed at the bottom of the flow-holding shell 13. The extrusion mechanisms are set on the bidirectional rotating column 28 and the limiting column 34.

[0025] Among them, the bidirectional motor 24 can control the bidirectional rotating column 28 to rotate, which in turn drives the active ring 3, which is engaged by the threaded collar 25, to move. The active ring 3 slides on the limiting column 34, so that the pressure roller 11 on the passive movable plate 4 can be close to or away from the fan-shaped filter. When close, the pressure roller 11 can squeeze the original pulp residue water attached to the outer surface of the filter bag 5, so that the pulp residue is tightly attached to the surface of the filter bag 5. The pulp water flows into the bent conduit 18 through the filter bag 5 and the inner cavity filter plate 16 and is discharged.

[0026] Specifically, the extrusion mechanism includes two symmetrically arranged active ring bars 3 and passive movable plates 4. The active ring bars 3 have limit holes 30 for inserting limit posts 34. A threaded collar 25 is also fixed on the active ring bars 3. The threaded collar 25 is threadedly connected to the bidirectional rotating column 28. Several pressure rollers 11 are rotatably connected to the outer wall of the two passive movable plates 4 that are close to each other. The original pulp adsorption plate is arranged between the two passive movable plates 4.

[0027] Specifically, the arc plate 29 has a slurry inlet 290, and a slurry inlet pipe 7 is inserted into one side of the outer wall of the side square shell 6. The slurry inlet pipe 7 passes through the side square shell 6 and is connected to the slurry inlet 290 and the inner air guide column 12 for introducing sterile finger slurry.

[0028] Based on the above implementation scheme, the working principle of this device is as follows: Initially, the sterile toilet paper production pulp, which has been stirred and doped with chemicals, is introduced into the flow container 13 through the pulp inlet pipe 7. The rotating motor 10 drives the passive rotating column 19 to rotate, causing the pulp adsorption plate to start rotating. The bidirectional motor 24 is controlled to make each pressure roller 11 closely adhere to the pulp adsorption plate, squeezing the pulp residue. The pulp residue flows from the inner cavity filter plate 16 until it enters the fixed ring plate 23 and is discharged through the water guide pipe 15 for recycling. The pulp residue on the compacted pulp adsorption plate continues to rotate. Under the inert cleaning gas entering through the bottom air passage 310, the filter bag 5 is slightly expanded, allowing some pulp residue on the outside of the filter bag 5 to fall off. Then, the bulging filter bag 5 is completely scraped off by the inclined scraper 27, achieving complete separation of pulp residue and water. Finally, it falls into the conveying platform 8 to enter the next process.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
