Description

Technical Field

[0001] This invention relates to the field of fiber processing technology, and in particular to a filtration system based on walnut shell fiber balls and its method of use. Background Technology

[0002] Fiber ball filter media is a spherical filter medium made of bundled fibers. Compared with traditional rigid filter media, it has advantages such as good elasticity, does not float on the water surface, has large pores, long working cycle, and low head loss. During the filtration process, the pore size of the filter layer gradually decreases along the water flow direction, which is more in line with the ideal filter media porosity distribution of larger pores at the top and smaller pores at the bottom. This results in advantages such as fast filtration speed, large dirt-holding capacity, good filtration effect, regeneration and repeated use without the need for complete replacement, saving time and labor.

[0003] A fiber ball filter, with publication number CN214019380U, relates to the field of filter technology. The filter includes a filter body and an inlet and outlet. A rotating drive unit on the top of the filter body drives a rotating shaft to rotate in either the forward or reverse direction. This causes a movable disc threadedly connected to the rotating shaft to move in the same or opposite direction relative to a fixed disc, increasing or decreasing the distance between the fixed and movable discs. This results in the fiber ball filter media, filled between the fixed and movable discs, being squeezed or filled with water. The process of repeatedly squeezing, filling, and squeezing the fiber balls cleans the filter media. The cleaning process is simple and convenient, eliminating the need for frequent machine shutdowns and manual removal of the filter media. It offers high cleaning efficiency and good cleaning effect. Furthermore, the squeezing method avoids the fiber ball breakage problem caused by mechanical stirring in existing technologies, resulting in a longer service life for the fiber ball filter media.

[0004] The aforementioned patent has several shortcomings in its application. First, in the filtration process of walnut shell fiber balls, wastewater adheres to the inner wall of the filter tank and is difficult to remove, resulting in poor filtration efficiency. Second, in the walnut shell fiber filtration process, the walnut shell fiber balls are unevenly distributed within the filter cylinder, leading to inconsistent filtration effects and uneven filtration. Third, in the preliminary filtration, excessive wastewater entering the preliminary filter screen can cause it to become clogged. Summary of the Invention

[0015] A method of using a filtration system based on walnut shell fiber balls includes the following steps:

[0016] Step 1: Before the operation begins, wastewater is injected into the filter tank body through the inlet pipe and inlet. The upper filter plate first performs preliminary filtration of the wastewater. The speed reduction gearbox slows down the rotation speed of the stirring device. Then, the speed reduction gearbox drives the scraper to rotate at the bottom of the upper filter plate, scraping the debris attached to the bottom of the upper filter plate into the inside of the anti-clogging filter screen. As the scraper rotates, the scraper and the anti-clogging filter screen move to the contact point. Then, the anti-clogging filter screen contacts the contact point. The contact point pushes the anti-clogging filter screen to squeeze the anti-clogging spring and tilt, pouring out the wastewater liquid inside the anti-clogging filter screen. Then, the anti-clogging filter screen no longer contacts the contact point. Under the action of the anti-clogging spring, the anti-clogging filter screen quickly resets and vibrates, promoting the separation of debris and liquid inside the anti-clogging filter screen.

[0017] Step 2: Subsequently, the wastewater moves through the upper filter plate to the walnut shell filter media. When the wastewater enters the filter tank, the helical gear reducer drives the agitator to rotate, which in turn rotates on the lower bearing seat to agitate the walnut shell filter media. The vent is used to discharge the medium to the outside of the filter tank. The vent valve and vent pipe work together. When the upper filter plate is blocked, the wastewater will be discharged from the overflow pipe to prevent damage to the inside of the filter tank due to excessive pressure and to protect the inside of the filter tank from overpressure.

[0018] Step 3: The transmission gear rotates with the stirring device, which in turn drives the transmission gear ring to rotate. The transmission gear ring then drives the first gear to rotate. With the connection of the scraping connecting rod, the first gear drives the second gear to rotate at the same speed. The second gear drives the scraping gear to rotate, which in turn drives the scraping sleeve and scraping frame to rotate, scraping away the debris and fibers on the inner wall of the filter tank. Since the number of teeth on the scraping gear is greater than that on the second gear, the speeds of the scraping gear and the second gear will be different. The number of teeth on the transmission gear is greater than that on the first gear, which will also cause the speeds of the transmission gear and the first gear to be different. This will result in the transmission gear and the scraping sleeve rotating at different speeds and in opposite directions.

[0019] Step 4: The speed of the mixing device is then reduced by the loosening reducer, which drives the loosening frame to rotate. The loosening motor can then be driven to rotate the loosening threaded rod, causing the loosening slide plate to slide on the loosening frame. As the loosening slide plate slides, it causes several loosening teeth to slide on the loosening track. The loosening grooves on the loosening slide plate, which are arranged in a downward-converging shape, adjust the spacing between the loosening teeth, thereby adjusting the loosening degree of the loosening mechanism on the walnut shell filter material.

[0020] Step 5: The filtered wastewater is then discharged through the lower filter plate. During the backwashing process of the filter tank body, water enters the filter tank body from the backwash inlet, and then passes through the lower filter plate, walnut shell filter media and upper filter plate in sequence before being discharged from the backwash outlet, cleaning the filter tank body.

[0021] Step 6: Workers can repair and inspect the filter tank body through the manhole, and can also install, disassemble, clean and repair the internal devices of the equipment through the handhole.

[0022] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0023] Firstly, before operation begins, wastewater is injected into the filter tank. The upper filter plate then performs preliminary filtration, while the anti-clogging mechanism continuously scrapes the bottom of the upper filter plate, removing filter residue stuck on it. The filtered wastewater then enters the filter tank itself, where an auxiliary mechanism continuously agitates the wastewater, promoting filtration within the tank. The scraping mechanism rotates with the auxiliary mechanism, continuously scraping the inner wall of the filter tank to remove debris and fiber residue, preventing obstruction of filtration. Simultaneously, a loosening mechanism continuously agitates the walnut shell filter media, ensuring even distribution and preventing poor filtration due to uneven distribution. Finally, the filtered wastewater is discharged through the lower filter plate.

[0024] Secondly, before operation begins, wastewater is injected into the filter tank body through the inlet pipe and inlet. The wastewater then passes through the upper filter plate, walnut shell filter media, and lower filter plate before being discharged from the outlet. During the backwashing process, water enters the filter tank body through the backwash inlet, then passes through the lower filter plate, walnut shell filter media, and upper filter plate before being discharged from the backwash outlet, thus cleaning the filter tank body. The manhole facilitates the maintenance and inspection of the filter tank body, while the handhole is for installing, disassembling, cleaning, and repairing the internal devices of the equipment. When the upper filter plate becomes clogged, wastewater will be discharged through the overflow pipe to prevent damage to the filter tank body due to excessive pressure.

[0025] Thirdly, the anti-clogging mechanism involves a gearbox that slows down the rotation speed of the agitator. The gearbox then drives a scraper to rotate at the bottom of the upper filter plate, scraping the debris attached to the bottom of the upper filter plate into the interior of the anti-clogging filter screen. As the scraper rotates, it moves to the contact point with the anti-clogging filter screen. The contact point then pushes the anti-clogging filter screen to compress the anti-clogging spring and tilt, pouring out the wastewater inside the anti-clogging filter screen. Afterward, the anti-clogging filter screen no longer contacts the contact point and, under the action of the anti-clogging spring, quickly resets, generating vibration to promote the separation of debris and liquid inside the anti-clogging filter screen, thus emptying the wastewater.

[0026] Fourth, the scraping mechanism consists of a transmission gear that rotates with the stirring device, which in turn drives a transmission gear ring. The transmission gear ring then drives the first gear, which, connected by the scraping connecting rod, drives the second gear to rotate at the same speed. The second gear then drives the scraping gear, which in turn drives the scraping sleeve and scraping frame to rotate, scraping away debris and fibers from the inner wall of the filter tank. Since the scraping gear has more teeth than the second gear, their rotational speeds differ. Similarly, the transmission gear has more teeth than the first gear, resulting in different rotational speeds between them. Consequently, the transmission gear and the scraping sleeve rotate at different rates and in opposite directions, improving the cleaning effect on the inner wall of the filter tank.

[0027] Fifth, the loosening mechanism reduces the rotation speed of the mixing device by a loosening reducer, which then drives the loosening frame to rotate. Subsequently, the loosening motor can be driven to rotate the loosening threaded rod, causing the loosening slide plate to slide on the loosening frame. As the loosening slide plate slides, it will cause several loosening teeth to slide on the loosening track. Several loosening grooves on the loosening slide plate, which are arranged in a downward-converging shape, will adjust the spacing between the loosening teeth, thereby adjusting the loosening degree of the loosening mechanism on the walnut shell filter material.

Walnut shell filter media 12 is provided inside the filter tank body 1, and the walnut shell filter media 12 is located between the upper filter plate 2 and the lower filter plate 11. Before operation, wastewater is injected... Inside the filter tank body 1, the upper filter plate 2 first performs preliminary filtration of the sewage. The anti-clogging mechanism 4 continuously scrapes the bottom of the upper filter plate 2, removing the filter residue stuck on the upper filter plate 2 into the anti-clogging mechanism 4. The filtered sewage then enters the filter tank body 1. Subsequently, the auxiliary mechanism 3 continuously agitates the sewage, promoting filtration of the sewage by the filter tank body 1. The scraping mechanism 5 rotates with the auxiliary mechanism 3, continuously scraping the inner wall of the filter tank body 1 to remove debris and fiber residue from the inner wall of the filter tank body 1, preventing obstruction of sewage filtration. At the same time, the loosening mechanism 6 continuously moves the walnut shell filter media 12 to ensure even distribution of the walnut shell filter media 12, preventing poor filtration due to uneven distribution of the walnut shell filter media 12. The filtered sewage is then discharged through the lower filter plate 11.

The filter tank body 1 is also provided with a manhole 23 and a handhole 24, a sight glass 27, an inlet pipe 25, and an overflow pipe 26. Before operation, wastewater is injected into the filter tank body 1 through the inlet pipe 25 and the inlet 21, and then flows sequentially through the upper filter plate. 2. Walnut shell filter media 12 and lower filter plate 11 are discharged from outlet 22. During the backwashing process of filter tank body 1, water enters the interior of filter tank body 1 from backwash inlet, and then passes through lower filter plate 11, walnut shell filter media 12 and upper filter plate 2 in sequence before being discharged from backwash outlet, cleaning filter tank body 1. Manhole 23 facilitates maintenance and inspection of filter tank body 1, while handhole 24 is for installing, disassembling, cleaning and repairing internal devices. When upper filter plate 2 is blocked, sewage will be discharged from overflow pipe 26 to prevent damage to the interior of filter tank body 1 due to excessive pressure.

[0043] Preferably, the filter tank body 1 is further provided with a vent 35 and a vent pipe 36. The auxiliary mechanism 3 includes a helical worm gear reducer 31, a stirring device 32, a lower bearing seat 33, and a vent valve 34. The helical worm gear reducer 31 is rotatably mounted on the top of the filter tank body 1. The lower bearing seat 33 is mounted on the lower filter plate 11. One end of the stirring device 32 is rotatably mounted on the filter tank body 1, and the other end is rotatably connected to the lower bearing seat 33. The vent valve 34 is disposed in the vent pipe 36. The stirring device 32 includes a stirring rotating shaft, an upper stirring paddle, and a lower stirring paddle. The stirring rotating shaft is rotatably mounted inside the filter tank body 1, and one end is connected to the main shaft of the helical worm gear reducer 31. The upper stirring paddle is mounted on the stirring rotating shaft, and the lower stirring paddle is mounted on the stirring rotating shaft and located below the upper stirring paddle. The stirring device 32 includes a stirring rotating shaft, an upper stirring paddle, and a lower stirring paddle. The stirring rotating shaft is used to transmit the rotation speed of the helical worm gear reducer 31 and transmit the driving force. The upper and lower stirring paddles are used to stir the inside of the filter tank body 1. When sewage enters the filter tank body 1, the helical worm gear reducer 31 will drive the stirring device 32 to rotate, which will drive the stirring device 32 to rotate on the lower bearing seat 33, stirring the walnut shell filter material 12. The vent 35 is used to discharge the medium to the outside of the filter tank body 1. The vent valve 34 and the vent pipe 36 cooperate to protect the inside of the filter tank body 1 from overpressure.

[0044] Preferably, the anti-clogging mechanism 4 includes a reduction gearbox 41, a scraper 42, an anti-clogging hinge rod 43, an anti-clogging filter 44, a contact protrusion 45, and two anti-clogging springs 46. The reduction gearbox 41 is connected to the stirring device 32, the scraper 42 is connected to the reduction gearbox 41, one end of the anti-clogging hinge rod 43 is hinged to the bottom of the scraper 42, and the anti-clogging filter 44 is installed at the other end of the anti-clogging hinge rod 43. The anti-clogging filter 44 can filter the scraped debris. The two ends of the two anti-clogging springs 46 are respectively installed and connected to the anti-clogging filter 44 and the scraper 42. The contact protrusion 45 is installed at the bottom of the upper filter plate 2. The anti-clogging mechanism 4 is controlled by the reduction gearbox 41 to control the stirring. The rotational speed of device 32 decreases, and then the reduction gearbox 41 drives the scraper 42 to rotate at the bottom of the upper filter plate 2, scraping the debris attached to the bottom of the upper filter plate 2 into the interior of the anti-clogging filter screen 44. As the scraper 42 rotates, the scraper 42 and the anti-clogging filter screen 44 move to the contact point 45. Then the anti-clogging filter screen 44 contacts the contact point 45, and the contact point 45 pushes the anti-clogging filter screen 44 to squeeze the anti-clogging spring 46 and tilt it, pouring out the sewage liquid inside the anti-clogging filter screen 44. Then the anti-clogging filter screen 44 no longer contacts the contact point 45. Under the action of the anti-clogging spring 46, the anti-clogging filter screen 44 quickly resets, generating vibration, promoting the separation of debris and liquid inside the anti-clogging filter screen 44, and pouring out the sewage.

[0045] Preferably, the scraping mechanism 5 includes a transmission gear 51, a transmission gear ring 52, a first gear 53, a scraping connecting rod 54, a second gear 55, a scraping gear 56, a scraping sleeve 57, and a scraping frame 58. The transmission gear 51 is fixedly sleeved on the stirring device 32. The transmission gear ring 52 is rotatably mounted on the upper filter plate 2 and meshes with the transmission gear 51. The first gear 53 is rotatably mounted on the upper filter plate 2 and meshes with the transmission gear ring 52. One end of the scraping connecting rod 54 is mounted on the first gear 53, and the second gear 55 is mounted on the other end of the scraping connecting rod 54. The scraping gear 56 is rotatably sleeved on the stirring device 32 and meshes with the second gear 55.

The scraping mechanism 5 is mounted on the inner wall of the filter tank body 1 and the scraping frame 58 is connected to the scraping sleeve 57. The scraping mechanism 5 is formed by the rotation of the transmission gear 51 with the stirring device 32, which in turn drives the transmission gear ring 52 to rotate. The transmission gear ring 52 drives the first gear 53 to rotate. Under the connection of the scraping connecting rod 54, the first gear 53 drives the second gear 55 to rotate at the same speed. The second gear 55 drives the scraping gear 56 to rotate, thereby driving the scraping sleeve 57 and the scraping frame 58 to rotate, scraping away the debris and fibers on the inner wall of the filter tank body 1. The number of teeth of the scraping gear 56 is greater than that of the second gear 55, which will cause the scraping gear 56 and the second gear 55 to rotate at different speeds. The number of teeth of the transmission gear 51 is greater than that of the first gear 53, which will cause the transmission gear 51 and the first gear 53 to rotate at different speeds. This will result in the transmission gear 51 and the scraping sleeve 57 rotating at different speeds and in opposite directions, which will improve the cleaning effect on the inner wall of the filter tank body 1.

[0046] Preferably, the loosening mechanism 6 includes a loosening reducer 61, a loosening frame 62, a loosening track 63, a loosening motor 64, a loosening threaded rod 65, a loosening slide plate 66, and a plurality of loosening teeth 67.

The loosening slide plate 66 and the loosening threaded rod 65 are threadedly engaged. The loosening slide plate 66 is provided with several loosening grooves that converge from top to bottom. Several loosening teeth 67 are slidably installed on the loosening track 63 and are respectively slidably locked in the loosening grooves. The loosening mechanism 6 reduces the rotation speed of the stirring device 32 by the loosening reducer 61, and then drives the loosening frame 62 to rotate. Then, the loosening motor 64 drives the loosening threaded rod 65 to rotate, which drives the loosening slide plate 66 to slide on the loosening frame 62. The sliding of the loosening slide plate 66 will drive the several loosening teeth 67 to slide on the loosening track 63. The several loosening grooves that converge from top to bottom on the loosening slide plate 66 will adjust the spacing between the loosening teeth 67, thereby adjusting the loosening degree of the loosening mechanism 6 on the walnut shell filter material 12.

[0047] A method of using a filtration system based on walnut shell fiber balls includes the following steps:

[0048] Step 1: Before the operation begins, wastewater is injected into the filter tank body 1 through the inlet pipe 25 and the inlet 21. The upper filter plate 2 first performs preliminary filtration of the wastewater. The speed reduction gearbox 41 slows down the rotation speed of the stirring device 32. Then, the speed reduction gearbox 41 drives the scraper 42 to rotate at the bottom of the upper filter plate 2, scraping the debris attached to the bottom of the upper filter plate 2 into the inside of the anti-clogging filter screen 44. As the scraper 42 rotates, the scraper 42 and the anti-clogging filter screen 44 move to the contact point 45. Then, the anti-clogging filter screen 44 contacts the contact point 45. The contact point 45 pushes the anti-clogging filter screen 44 to squeeze the anti-clogging spring 46 and tilt it, pouring out the wastewater liquid in the anti-clogging filter screen 44. Then, the anti-clogging filter screen 44 no longer contacts the contact point 45. Under the action of the anti-clogging spring 46, the anti-clogging filter screen 44 quickly resets and vibrates, promoting the separation of debris and liquid in the anti-clogging filter screen 44.

[0049] Step 2: Subsequently, the sewage moves through the upper filter plate 2 to the walnut shell filter media 12. When the sewage enters the filter tank body 1, the helical worm gear reducer 31 drives the stirring device 32 to rotate, which in turn drives the stirring device 32 to rotate on the lower bearing seat 33, stirring the walnut shell filter media 12. The vent 35 is used to discharge the medium to the outside of the filter tank body 1. The vent valve 34 and the vent pipe 36 cooperate. When the upper filter plate 2 is blocked, the sewage will be discharged from the overflow pipe 26 to prevent the filter tank body 1 from being damaged due to excessive pressure and to protect the filter tank body 1 from overpressure.

[0050] Step 3: The transmission gear 51 rotates with the stirring device 32, which in turn drives the transmission gear ring 52 to rotate. The transmission gear ring 52 drives the first gear 53 to rotate. Under the connection of the scraping connecting rod 54, the first gear 53 drives the second gear 55 to rotate at the same speed. The second gear 55 drives the scraping gear 56 to rotate, thereby driving the scraping sleeve 57 and the scraping frame 58 to rotate, scraping away the debris and fibers on the inner wall of the filter tank body 1. Since the number of teeth of the scraping gear 56 is greater than that of the second gear 55, the rotation speeds of the scraping gear 56 and the second gear 55 will be different. The number of teeth of the transmission gear 51 is greater than that of the first gear 53, which will also cause the rotation speeds of the transmission gear 51 and the first gear 53 to be different. This will result in the transmission gear 51 and the scraping sleeve 57 rotating at different speeds and in opposite directions.

[0051] Step 4: The speed of the mixing device 32 is then reduced by the loosening reducer 61, which in turn drives the loosening frame 62 to rotate. Then, the loosening motor 64 drives the loosening threaded rod 65 to rotate, which in turn drives the loosening slide plate 66 to slide on the loosening frame 62. As the loosening slide plate 66 slides, it will drive several loosening teeth 67 to slide on the loosening track 63. Several loosening grooves on the loosening slide plate 66 that are gathered from top to bottom will adjust the spacing between the loosening teeth 67, thereby adjusting the loosening degree of the loosening mechanism 6 on the walnut shell filter material 12.
