Description

Technical Field

[0001] This invention relates to the field of toilet paper production technology, specifically to an environmentally friendly sludge treatment device for toilet paper production. Background Technology

[0002] The production of toilet paper generates a large amount of industrial wastewater containing fibers, fillers, and chemicals (such as flocculants and bleaching agents). If this wastewater is discharged directly without effective treatment, it will not only cause environmental pollution but also waste water resources. Currently, commonly used sludge treatment methods in the industry mainly include sedimentation, filtration, and centrifugation; however, these technologies still have many problems in practical applications.

[0003] Traditional mixing equipment typically uses a single stirring method, resulting in insufficient reaction between wastewater and flocculant, affecting subsequent solid-liquid separation. Ordinary centrifugal separators, after prolonged operation, are prone to clogging filter pores with sludge, reducing separation efficiency and requiring frequent shutdowns for cleaning, impacting production efficiency. Cleaning of existing equipment usually relies on manual labor or simple rinsing, which is insufficient to thoroughly remove residual sludge, and long-term accumulation can affect equipment lifespan. Traditional sludge treatment equipment relies on manual operation, has low automation, and high energy consumption, failing to meet modern environmental protection and energy-saving production requirements.

[0004] With increasingly stringent environmental regulations, the paper industry has an urgent need for efficient, energy-saving, and intelligent sludge treatment equipment. Summary of the Invention

[0005] To address the problems of low reaction efficiency and poor reaction sufficiency between wastewater and flocculant solution in existing technologies, poor separation efficiency and effect of wastewater after reaction, and lack of a cleaning mechanism for the wastewater separation components after reaction, the present invention aims to provide an environmentally friendly sludge treatment device for toilet paper production.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: an environmentally friendly sludge treatment device for toilet paper production, including a supporting base frame, a mixing mechanism and a separation mechanism.

The auxiliary mechanism ensures the normal operation of the separation mechanism, the flushing mechanism and the cleaning aid mechanism. In addition, the separation mechanism can use centrifugal force to throw the water in the wastewater after the reaction into the intercepting outer cylinder and intercept sludge and other substances in the separation orifice.

The sealing top ring is rotatably connected to the top end of the separation orifice cylinder, and a V-shaped scraper rod for use with the separation orifice cylinder is fixedly mounted on the inner side of the sealing top ring, so that the V-shaped scraper rod fits against the inner wall of the separation orifice cylinder and forms a scraping motion on the inner wall of the separation orifice cylinder.

[0011] The auxiliary mechanism includes a sealing top plate and an mounting horizontal plate.

[0032] Example: Figures 1-9 As shown, this invention provides an environmentally friendly sludge treatment device for toilet paper production, including a support frame 1, a mixing mechanism 2, and a separation mechanism 3.

The mixing mechanism 2 includes a first mixing plate 211 and a second mixing plate 217. The separation mechanism 3 includes an intercepting outer cylinder 32 and a separation orifice cylinder 35, and the separation orifice cylinder 35 is sleeved inside the intercepting outer cylinder 32 (see details). Figure 6 (as shown)

[0033] The mixing mechanism 2 can guide the sewage from the bottom to the top and simultaneously mix it in two spaces of different sizes through the first mixing plate 211 and the second mixing plate 217 while it is circulating. The auxiliary mechanism 4 ensures the normal operation of the separation mechanism 3, the flushing mechanism 5 and the cleaning aid mechanism 6. In conjunction with the separation mechanism 3, it can use centrifugal force to throw the water in the reacted sewage into the intercepting outer cylinder 32 and intercept sludge and other substances in the separation orifice cylinder 35. The flushing mechanism 5 and the cleaning aid mechanism 6 can flush the rotating separation orifice cylinder 35 from the outside to the inside and can also suck and clean the rotating separation orifice cylinder 35 from the outside to the inside.

[0034] The mixing mechanism 2 also includes a mixing cylinder 21, which is fixedly mounted on the support base 1. The top of the mixing cylinder 21 is connected to a feed conduit 22 and a return conduit 23 for use. The end of the return conduit 23 is fixedly connected to a mixing aid cylinder 24, and the upper end of the mixing aid cylinder 24 is connected to a discharge conduit 25 for use. The ends of the return conduit 23 and the discharge conduit 25 that are close to each other are respectively provided with a first solenoid valve and a second solenoid valve for use. The bottom end of the mixing aid cylinder 24 is connected to a cleaning aid conduit 26 for use. The cleaning aid conduit 26 is provided with a third solenoid valve for use. The bottom end of the mixing cylinder 21 is fixedly mounted with a first pump body 27, and the lower end of the first pump body 27 is fixedly connected to a L-shaped connecting pipe 28 and a transverse connecting pipe 29 for use. The end of the L-shaped connecting pipe 28 is connected to the bottom end of the mixing cylinder 21, and the end of the transverse connecting pipe 29 is connected to the lower end of the mixing aid cylinder 24. The upper end of the L-shaped connecting pipe 28 is provided with a fourth solenoid valve for use.

[0035] A first rotating rod 210 is rotatably inserted into the mixing cylinder 21, and a first bevel gear 212 and a first synchronous pulley 213 are fixedly sleeved on the first rotating rod 210 for cooperation. A first mixing plate 211 is fixedly sleeved on the first rotating rod 210. A first servo motor 214 is fixedly installed at the top of the mixing cylinder 21, and a second bevel gear 215 is fixedly connected to the output end of the first servo motor 214, so that the second bevel gear 215 and the first rotating rod 210 are coaxially fixed. The second bevel gear 215 meshes with the first bevel gear 212, and the rotation of the first servo motor 214 synchronously drives the second bevel gear 212. The first rotating rod 210 connected to 215 rotates, and a support base 220 is fixedly installed at the top of the mixing cylinder 21. The first servo motor 214 is fixedly installed on the support base 220. The use of the support base 220 provides a guarantee for the stable installation of the first servo motor 214. A second rotating rod 216 is rotatably inserted into the mixing cylinder 24, and a second synchronous wheel 218 is fixedly sleeved on the second rotating rod 216 for cooperation. The second mixing plate 217 is fixedly sleeved on the second rotating rod 216. The second synchronous wheel 218 and the outer side of the first synchronous wheel 213 are meshed with a transmission synchronous belt 219.

[0036] By adopting the above technical solution, during use, an appropriate amount of wastewater and flocculant solution generated during toilet paper production is introduced into the mixing cylinder 21 through the feed conduit 22. Then, the second and third solenoid valves are closed and the first and fourth solenoid valves, the first servo motor 214, and the first pump body 27 are started. At this time, the first servo motor 214 will drive the second bevel gear 215 to rotate, which in turn drives the first rotating rod 210 to rotate through the first bevel gear 212, which in turn drives the first mixing plate 211 and the first synchronous pulley 213 to rotate. Furthermore, the transmission synchronous belt 219 drives the second synchronous pulley 218 to rotate, which in turn drives the second mixing plate 217 to rotate through the second rotating rod 216. At the same time, the first pump body 27 can introduce the wastewater at the bottom of the mixing cylinder 21 into the mixing aid cylinder 24 through the L-shaped connecting pipe 28 and the transverse connecting pipe 29, and then into the top of the mixing cylinder 21 through the mixing aid cylinder 24 and the return conduit 23.

[0037] The separation mechanism 3 also includes a water storage tank 31, an intercepting outer cylinder 32 fixedly mounted on a support base 1, and a connecting vertical pipe 33 connecting the intercepting outer cylinder 32 and the water storage tank 31. A discharge conduit 34 is rotatably inserted into the bottom end of the intercepting outer cylinder 32, and a separation orifice cylinder 35 is fixedly mounted on the top end of the discharge conduit 34. A fifth solenoid valve is provided on the discharge conduit 34, and a driven gear ring 36 is fixedly sleeved on the bottom end of the discharge conduit 34. A second servo motor 37 is fixedly mounted on the lower end of the intercepting outer cylinder 32, and a drive gear 38 is fixedly sleeved on the end of the output end of the second servo motor 37. A mounting bracket 312 is fixedly mounted on the lower end of the intercepting outer cylinder 32, and the fifth solenoid valve 35 is fixedly mounted on the top end of the support base 1. The second servo motor 37 is fixedly inserted into the mounting bracket 312. The mounting bracket 312 ensures the stable installation of the second servo motor 37. The drive gear 38 meshes with the driven gear ring 36 to achieve transmission. A side crossbar 39 is fixedly installed on the top of the inner cavity of the intercepting outer cylinder 32, and a sealing top ring 310 is fixedly connected to the end of the side crossbar 39. The sealing top ring 310 is rotatably connected to the top of the separation cylinder 35, and a V-shaped scraper 311 that cooperates with the separation cylinder 35 is fixedly installed on the inner side of the sealing top ring 310. The V-shaped scraper 311 fits against the inner wall of the separation cylinder 35 and scrapes the inner wall of the separation cylinder 35 (see details). Figure 6 (As shown).

[0038] For details, please refer to Table 1 for a comparison of solid-liquid separation effects:

[0041] This solution adopts an optimized centrifugal structure and V-shaped scraper design to reduce the sludge moisture content, improve processing capacity, and significantly reduce filter clogging.

[0042] The auxiliary mechanism 4 includes a sealing top plate 41 and a mounting horizontal plate 42. The sealing top plate 41 is rotatably sleeved on the bottom end of the discharge conduit 25, and the sealing top plate 41 slides and fits against the top of the intercepting outer cylinder 32 and the sealing top ring 310. A first gear 43 is fixedly sleeved on the sealing top plate 41. The mounting horizontal plate 42 is fixedly sleeved on the lower end of the discharge conduit 25, and a third servo motor 44 is fixedly installed on one side of the top end of the mounting horizontal plate 42. The output end of the third servo motor 44 rotates through the mounting horizontal plate 42 and a second gear 45 is fixedly sleeved at its end, and the second gear 45 meshes with the first gear 43.

[0043] By adopting the above technical solution, during use, after the wastewater to be treated has fully reacted with the flocculant solution, the first servo motor 214 and the first solenoid valve are closed, and the second solenoid valve is opened. At this time, the fully reacted wastewater will be introduced into the separation orifice 35 through the discharge conduit 25. When an appropriate amount of fully reacted wastewater is introduced into the separation orifice 35, the first pump body 27 is paused, and then the second servo motor 37 is started, which can drive the drive gear 38 to rotate, and then drive the discharge conduit 34 to rotate through the driven gear ring 36, which in turn can drive the separation orifice 35 to rotate. This allows the centrifugal force to throw the water from the wastewater after the reaction into the outer interceptor cylinder 32 and to intercept the sludge and other substances in the separation orifice cylinder 35. At the same time, the thrown-out water will be introduced into the water storage tank 31 through the connecting vertical pipe 33, and the V-shaped scraper bar 311 can simultaneously scrape off the sludge and other substances on the inner wall of the separation orifice cylinder 35. After the wastewater separation operation in the separation orifice cylinder 35 is completed, the fifth solenoid valve is opened and the intercepted sludge and other substances are discharged through the discharge pipe 34. Then, the wastewater treatment operation generated during the subsequent toilet paper production is carried out according to the above steps.

[0044] When the separation tube 35 becomes blocked, the third servo motor 44 is activated, which drives the second gear 45 to rotate, which in turn drives the first gear 43 to rotate, and further drives the sealing top plate 41 to rotate. The third servo motor 44 is paused when the plate rotates 90 degrees.

[0045] Please refer to Table 2 below for details:

[0048] This invention employs a two-stage mixing (main mixing + auxiliary mixing) + circulation reflux design, which significantly improves mixing uniformity, shortens flocculation time, and reduces energy consumption.

[0049] The flushing mechanism 5 includes a mounting base 51 and a second pump body 52. ​​The mounting base 51 is fixedly installed on the top of the water storage tank 31, and a multi-stage electric push rod 53 is fixedly inserted into the mounting base 51. A lifting bracket 54 is fixedly sleeved at the output end of the multi-stage electric push rod 53, and the lifting bracket 54 is slidably connected to the mounting base 51. An L-shaped flushing pipe 55 is fixedly inserted into the lifting bracket 54, and one end of the L-shaped flushing pipe 55 is fixedly connected to a flushing vertical pipe 56. The flushing vertical pipe 56 can be inserted between the intercepting outer cylinder 32 and the separation hole cylinder 35, and a flushing through groove 57 for matching use is opened on the flushing vertical pipe 56. The other end of the L-shaped flushing pipe 55 is fixedly connected to a connecting hose 58.

[0050] The second pump body 52 is fixedly installed at the bottom of the inner cavity of the water storage tank 31, and the bottom end of the second pump body 52 is provided with an L-shaped inlet pipe 59 and an L-shaped outlet pipe 510 for use. The L-shaped outlet pipe 510 is fixedly inserted into the water storage tank 31, and the top end of the L-shaped outlet pipe 510 is fixedly connected to the connecting hose 58.

[0051] The cleaning aid mechanism 6 includes an L-shaped cleaning aid cylinder 61, which is fixedly installed on the lifting bracket 54. An L-shaped cleaning aid tube 62 is fixedly connected to the lower end of the L-shaped cleaning aid cylinder 61. The L-shaped cleaning aid tube 62 is fixedly inserted into the lifting bracket 54, and a V-shaped cleaning aid tube 63 is fixedly connected to the bottom end of the L-shaped cleaning aid tube 62. The V-shaped cleaning aid tube 63 can be inserted into the separation hole cylinder 35, and a matching cleaning aid through groove 64 is opened through the V-shaped cleaning aid tube 63. An inner grid plate 65 is fixedly connected to the inner side of the upper end of the L-shaped cleaning aid cylinder 61, and a cleaning aid fan 66 is fixedly inserted into the middle of the inner grid plate 65. A matching separator filter 67 is fixedly installed at the top of the L-shaped cleaning aid cylinder 61. A matching interception inclined plate 68 is integrally formed in the inner cavity of the L-shaped cleaning aid cylinder 61. The interception inclined plate 68 can effectively prevent the sucked-in impurities from being guided to the upper end of the L-shaped cleaning aid tube 62.

[0052] By adopting the above technical solution, when in use, the multi-stage electric push rod 53 is activated, which drives the lifting bracket 54 to move down, thereby driving the flushing vertical pipe 56 and the V-shaped cleaning aid pipe 63 to move down. When the flushing vertical pipe 56 and the V-shaped cleaning aid pipe 63 move down to the lowest point, the multi-stage electric push rod 53 is turned off and the second servo motor 37, the second pump body 52 and the cleaning aid fan 66 are activated. At this time, the separated water source will be introduced into the connecting hose 58 through the L-shaped liquid inlet pipe 59 and the L-shaped liquid outlet pipe 510. Then the separated water source will be introduced into the flushing vertical pipe 56 through the L-shaped flushing pipe 55 and discharged through the flushing channel 57, thereby flushing the rotating separation cylinder 35 from the outside to the inside.

[0053] Meanwhile, the cleaning fan 66 can continuously discharge air from the L-shaped cleaning cylinder 61, thereby continuously discharging air from the V-shaped cleaning pipe 63 through the L-shaped cleaning pipe 62. This allows the rotating separation cylinder 35 to be cleaned from the outside in through the cleaning groove 64. Some of the water stains and sludge sucked out will be temporarily stored in the L-shaped cleaning cylinder 61. After the separation cylinder 35 is cleaned, the water stains and sludge in the L-shaped cleaning cylinder 61 will flow into the separation cylinder 35 and be discharged. In addition, the flushing vertical pipe 56 and the V-shaped cleaning pipe 63 will move upward and reset.

[0054] Working principle: During use, an appropriate amount of wastewater and flocculant solution generated during toilet paper production is introduced into the mixing cylinder 21 through the feed pipe 22. Then, the second and third solenoid valves are closed and the first and fourth solenoid valves, the first servo motor 214, and the first pump body 27 are started. At this time, the first servo motor 214 will drive the second bevel gear 215 to rotate, which in turn drives the first rotating rod 210 to rotate through the first bevel gear 212, which in turn drives the first mixing plate 211 and the first synchronous pulley 213 to rotate. Furthermore, the transmission synchronous belt 219 drives the second synchronous pulley 218 to rotate, which in turn drives the second mixing plate 217 to rotate through the second rotating rod 216. At the same time, the first pump body 27 can introduce the wastewater at the bottom of the mixing cylinder 21 into the mixing aid cylinder 24 through the L-shaped connecting pipe 28 and the horizontal connecting pipe 29, and then into the top of the mixing cylinder 21 through the mixing aid cylinder 24 and the return pipe 23.

[0055] After the wastewater to be treated reacts fully with the flocculant solution, the first servo motor 214 and the first solenoid valve are closed and the second solenoid valve is opened. At this time, the fully reacted wastewater will be introduced into the separation tube 35 through the discharge pipe 25. When an appropriate amount of fully reacted wastewater is introduced into the separation tube 35, the first pump body 27 is paused, and then the second servo motor 37 is started, which can drive the drive gear 38 to rotate, and then drive the discharge pipe 34 to rotate through the driven gear ring 36, which can further drive the separation tube 35 to rotate. Thus, the water in the reacted wastewater can be thrown out into the intercepting outer cylinder 32 by the action of centrifugal force, and the sludge and other substances can be intercepted in the separation tube 35. At the same time, the thrown water will be introduced into the water storage tank 31 through the connecting vertical pipe 33, and the V-shaped scraper bar 311 can simultaneously scrape off the sludge and other substances on the inner wall of the separation tube 35. After the wastewater separation operation in the separation tube 35 is completed, the fifth solenoid valve is opened and the intercepted sludge and other substances are discharged through the discharge pipe 34. Then, the wastewater treatment operation generated during the subsequent toilet paper production is carried out according to the above steps.

[0056] When the separation tube 35 becomes blocked, the third servo motor 44 is activated, which drives the second gear 45 to rotate, which in turn drives the first gear 43 to rotate, and further drives the sealing top plate 41 to rotate. The third servo motor 44 is paused when the plate rotates ninety degrees.

[0057] Then, the multi-stage electric push rod 53 is activated, which drives the lifting bracket 54 to move down, thereby driving the flushing vertical pipe 56 and the V-shaped cleaning aid pipe 63 to move down. When the flushing vertical pipe 56 and the V-shaped cleaning aid pipe 63 move down to the lowest point, the multi-stage electric push rod 53 is closed and the second servo motor 37, the second pump body 52 and the cleaning aid fan 66 are activated. At this time, the separated water source will be introduced into the connecting hose 58 through the L-shaped liquid inlet pipe 59 and the L-shaped liquid outlet pipe 510. Then, the separated water source will be introduced into the flushing vertical pipe 56 through the L-shaped flushing pipe 55 and discharged through the flushing channel 57, thereby flushing the rotating separation cylinder 35 from the outside to the inside.

[0058] Meanwhile, the cleaning fan 66 can continuously discharge air from the L-shaped cleaning cylinder 61, thereby continuously discharging air from the V-shaped cleaning pipe 63 through the L-shaped cleaning pipe 62. This allows the rotating separation cylinder 35 to be cleaned from the outside in through the cleaning groove 64. Some of the water stains and sludge sucked out will be temporarily stored in the L-shaped cleaning cylinder 61. After the separation cylinder 35 is cleaned, the water stains and sludge in the L-shaped cleaning cylinder 61 will flow into the separation cylinder 35 and be discharged. In addition, the flushing vertical pipe 56 and the V-shaped cleaning pipe 63 will move upward and reset.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
