Description

Technical Field

[0001] This invention relates to the field of water-reducing agent filtration technology, and more specifically, to a concrete water-reducing agent filtration device and its method of use. Background Technology

[0002] Water-reducing agents are chemical products obtained by sulfonation, condensation, neutralization, and other reactions from methylnaphthalene and sulfur trioxide. The preparation process involves chemical reactions and produces a large number of impurities. Therefore, filtration is an essential step in the production of water-reducing agents. As a core component of concrete admixtures, the performance of water-reducing agents directly affects the workability, strength, and durability of concrete. If water-reducing agents are not filtered, not only will the quality of the water-reducing agents themselves be affected, but the quality of downstream concrete will also be further affected.

[0003] Existing filtration equipment can only clean impurities after the entire batch of water-reducing agent has been filtered. The filtered impurities tend to accumulate near the filter holes, causing blockage and reducing the filtration efficiency of the water-reducing agent. In other words, the cleaning action and the filtration process are separated in time. Cleaning can only be carried out after filtration is completed, while impurities continue to accumulate during the filtration process, resulting in a decreasing filtration efficiency.

[0015] A method of using a concrete water-reducing agent filtration device, the method comprising the following steps: S1: The concrete water-reducing agent to be filtered is fed into the treatment tank through the feed pipe; S2: The water-reducing agent is guided into the conical filter after passing through the liquid guide hopper. After preliminary filtration by the conical filter, the filtrate passes through the sieve plate into the bottom of the spherical cylinder and is then discharged through the discharge pipe. S3: During the filtration process of the water-reducing agent, the drive assembly is activated to drive the liquid guide bucket to rotate. The liquid guide bucket drives the first scraper to rotate synchronously, so that the first scraper continuously scrapes off the impurities attached to the surface of the conical filter bucket. The scraped-off impurities fall into the collection cylinder for collection. S4: At the same time, the ring gear drives the rotating rod to rotate through the support plate, causing the screen plate to rotate to change the position of the filter hole, and drives the second scraper to make a circular motion along the inner wall of the spherical cylinder to scrape off the fine impurities attached to the inner wall of the spherical cylinder. S5: Start the second servo motor to drive the winding roller to rotate. Through the meshing of the main gear and the driven gear, the feeding roller is driven to rotate synchronously in the opposite direction, so that the filter cloth moves continuously and passes through the flow slots on both sides of the processing box to assist in the filtration of the water-reducing agent. At the same time, the old filter cloth is wound up and the new filter cloth is released, realizing the continuous renewal of the filter medium. S6: When the filter cloth moves to the storage box area, the water pump is started, and the filter cloth is sprayed from top to bottom in both directions through the No. 1 spray plate and the No. 2 spray plate to soften and wash away the embedded gel particles; at the same time, the electric telescopic rod periodically drives the No. 2 cleaning plate to intermittently scrape the surface of the filter cloth, and the peeled dirt is discharged through the liquid outlet pipe.

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: This solution incorporates a filtration mechanism, a flow guiding mechanism, an anti-clogging mechanism, and a drive assembly. During the filtration process of the water-reducing agent, the first scraper is simultaneously driven to continuously scrape away impurities from the surface of the conical filter bucket, while the anti-clogging mechanism assists in cleaning the inside of the spherical cylinder. This achieves simultaneous cleaning and filtration, prevents impurities from accumulating near the filter holes and causing blockages, and maintains the filtration efficiency without decreasing.

[0017] By setting up an anti-clogging mechanism, during the filtration process of the water-reducing agent, the ring gear drives the rotating rod to rotate synchronously, causing the screen plate to change the position of the filter holes and the second scraper to scrape away fine impurities by making a circular motion along the inner wall of the spherical cylinder. This effectively avoids the accumulation of impurities on the surface of the filter medium and the inner wall of the cavity, and completely solves the problems of reduced filtration efficiency and incomplete cleaning caused by the separation of cleaning and filtration time in traditional filtration equipment.

[0018] By setting up a winding mechanism, filter cloth, and recycling mechanism to drive the filter cloth to move continuously and replace automatically, backwash the filter cloth, and guide the waste liquid to the recycling box for centralized collection via a guide plate, the self-cleaning and continuous filtration of the filter cloth are achieved, the downtime for replacement due to filter cloth blockage is avoided, production efficiency is improved, and the resource recovery of filter residue is realized.

[0019] By setting up a rinsing mechanism and a cleaning mechanism, the rinsing mechanism can spray the filter cloth from both above and below to soften the gel and sticky impurities while the filter cloth is moving continuously. The cleaning mechanism's electric telescopic rod drives the No. 2 cleaning plate to intermittently scrape and forcibly peel off stubborn dirt. This achieves the synergistic effect of rinsing and scraping, significantly improving the cleaning effect and regeneration quality of the filter cloth. It effectively solves the problems of incomplete cleaning and shortened filter cloth life caused by a single rinsing method. Attached Figure Description

[0023] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0024] The following is a detailed description of a concrete water-reducing agent filtration device and its usage method provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 10As shown, this embodiment of the invention provides a concrete water-reducing agent filtration device and its usage method, including a treatment box 1. A top sealing plate 2 is fixedly connected to the top of the treatment box 1, and a feed pipe 3 is fixedly connected to the middle of the top of the top sealing plate 2. A discharge pipe 4 is fixedly connected to the bottom of the treatment box 1. A filtration mechanism 5 for filtering water-reducing agents is provided at the upper end of the inside of the treatment box 1. The filtration mechanism 5 includes a spherical cylinder 51 located inside the treatment box 1. Support rods 52 are fixedly connected to both sides of the outer circular surface of the spherical cylinder 51. Support cylinders for supporting the support rods 52 are provided on both sides of the inner wall of the treatment box 1. A sieve plate 53 is provided in the middle of the inside of the spherical cylinder 51. A conical filter hopper 54 is fixedly connected to the top opening of the spherical cylinder 51. A collection cylinder 55 fixedly connected to the spherical cylinder 51 is provided at the bottom edge of the conical filter hopper 54. The conical filter 54 is provided with a flow guiding mechanism 6 above it to guide the flow direction of the water reducing agent. The flow guiding mechanism 6 includes a liquid guiding hopper 62 located above the conical filter 54. A support plate 63 is fixedly connected to the outer circular surface of the liquid guiding hopper 62. A support bracket 61 for supporting the support plate 63 is provided at the top of the inner side of the treatment box 1. A liquid guiding groove 64 is opened at the bottom of the liquid guiding hopper 62. A first scraper 65 is fixedly connected to the bottom of the liquid guiding hopper 62 near the liquid guiding groove 64. The spherical cylinder 51 is also provided with an anti-clogging mechanism 7 and a drive assembly for driving the liquid guiding hopper 62 to rotate. When the drive assembly drives the liquid guide hopper 62 to rotate, it drives the first scraper 65 to rotate synchronously, so that the first scraper 65 continuously scrapes off the impurities attached to the surface of the conical filter hopper 54 during the water-reducing agent filtration process, realizing the simultaneous cleaning and filtration.

[0026] like Figures 1 to 10 As shown, the bottom of the spherical cylinder 51 is provided with a circular discharge port. The drive assembly includes a ring gear 66 fixedly connected to the top of the liquid guide hopper 62. A gear disk 67 is meshed with the outer surface of the ring gear 66. A first servo motor 69 is fixedly installed on the upper surface of the top sealing plate 2. A drive rod 68 for driving the gear disk 67 is fixedly connected to the output end of the first servo motor 69.

[0027] To address the problem of existing filtration equipment where the cleaning action and filtration process are separated in time (i.e., impurities can only be cleaned after the entire batch of water-reducing agent has been filtered, leading to continuous accumulation of impurities and a decreasing trend in filtration efficiency), the above-mentioned technical solution is adopted. This solution mainly consists of a filtration mechanism 5, a flow guiding mechanism 6, an anti-clogging mechanism 7, and a drive assembly. In operation, the concrete water-reducing agent to be filtered first enters the processing tank 1 through the feed pipe 3. Guided by the liquid guiding hopper 62, the water-reducing agent flows out from the liquid guiding trough 64 and falls onto the conical filter hopper 54. The water-reducing agent undergoes preliminary filtration on the surface of the conical filter hopper 54, where larger particles are trapped on the upper surface. The filtrate then flows downwards into the spherical cylinder 51 through filter holes inside the conical filter hopper 54. The filtrate flowing into the spherical cylinder 51 undergoes further secondary filtration through the sieve plate 53. The purified water-reducing agent is discharged from the discharge pipe 4 at the bottom of the treatment tank 1. During the filtration process, the first servo motor 69 is started, which drives the gear plate 67 to rotate via the drive rod 68. The gear plate 67 drives the ring gear 66 to rotate, and the ring gear 66 drives the liquid guide hopper 62 to rotate smoothly under the support of the support bracket 61 and the support plate 63. Since the first scraper 65 is fixedly connected to the bottom of the conical filter hopper 54 near the liquid guide trough 64 and rotates synchronously with the liquid guide hopper 62, the first scraper 65 continuously moves in a circular motion along the surface of the conical filter hopper 54 during the water-reducing agent filtration process, continuously scraping off the solid impurities attached to the surface of the conical filter hopper 54. The scraped impurities fall into the collection cylinder 55 under the action of gravity and are collected, thereby avoiding the accumulation of impurities near the filter holes for a long time and causing blockage. At the same time, the anti-clogging mechanism 7 can further assist in cleaning the inside of the spherical cylinder 51 to ensure the smooth flow of the entire filtration channel.

[0028] like Figures 1 to 10 As shown, the anti-clogging mechanism 7 includes a support plate 71 fixedly connected inside the ring gear 66. A rotating rod 72 is fixedly connected inside the support plate 71. The rotating rod 72 passes through the liquid guide hopper 62, the conical filter hopper 54, and the sieve plate 53 and is fixedly connected to a third scraper 75. The sieve plate 53 is fixedly connected to the rotating rod 72. The bottom of the sieve plate 53 is provided with a second scraper 74 fixedly connected to the rotating rod 72. The top of the rotating rod 72 is provided with a limiting seat 73 fixedly connected to the inner wall of the treatment tank 1.

[0029] like Figures 1 to 10 As shown, the second scraper 74 is crescent-shaped, and its cleaning end abuts against the inner wall of the spherical cylinder 51; while the first scraper 65 is rectangular, and its cleaning end abuts against the surface of the conical filter 54.

[0030] To address the issues of existing filtration equipment that only cleans impurities after the entire batch of water-reducing agent has been filtered, leading to continuous impurity accumulation and decreasing filtration efficiency, and the limitations of existing scraper structures that result in incomplete cleaning, a new design is implemented. This design utilizes a conical filter hopper 54 for initial filtration of the water-reducing agent. The filtrate then flows through filter holes into a spherical cylinder 51, undergoes secondary filtration via a sieve disc 53, and finally, the purified water-reducing agent is discharged from the outlet pipe 4. Simultaneously, as the ring gear 66 rotates, the internally fixed support plate 71 drives the rotating rod 72 to rotate synchronously. Since the sieve disc 53 is fixedly connected to the rotating rod 72, its rotation causes the filter holes on the disc to continuously change position, preventing impurities from accumulating in the same location. Furthermore, the top of the rotating rod 72 is equipped with a limiting seat 73, fixedly connected to the inner wall of the processing tank 1, ensuring smooth rotation of the rotating rod 72 without axial movement. During the rotation of the rotating rod 72, the second scraper 74, which is fixedly connected to it, rotates accordingly. Since the second scraper 74 is crescent-shaped, its cleaning end abuts against the inner wall of the spherical cylinder 51. As the rotating rod 72 rotates, the second scraper 74 moves in a circular motion along the inner wall of the spherical cylinder 51, scraping away the fine impurities attached to the inner wall of the spherical cylinder 51, preventing impurities from accumulating on the inner wall and re-mixing into the filtrate. During this filtration operation, the continuous rotation and cleaning by the first scraper 65 and the second scraper 74 during the filtration process eliminates the need for separate cleaning after stopping the machine, completely solving the problem of reduced filtration efficiency caused by the separation of cleaning and filtration time in traditional filtration equipment. Furthermore, the first scraper 65 cleans the surface of the conical filter hopper 54, while the second scraper 74 cleans the inner wall of the spherical cylinder 51, forming a full-path anti-clogging system from feeding to discharging, effectively preventing the accumulation of impurities on the surface of the filter medium and the inner wall of the cavity.

[0031] like Figures 1 to 10 As shown, the processing box 1 is provided with a recycling mechanism 8 and a storage component 9 on both sides, and a flow channel 11 is provided on both sides of the processing box 1 to cooperate with it; a filter cloth 12 for filtration is provided inside the flow channel 11; the recycling mechanism 8 includes a recycling box 81 fixedly connected to one side of the outer surface of the processing box 1, a rear sealing plate 83 is bolted to the rear side of the recycling box 81, a transparent plate 82 is fixedly connected to the top of the recycling box 81, a recycling box 85 is fixedly connected to one side of the recycling box 81, and a guide plate 84 is fixedly connected at an incline in the middle of the inside of the recycling box 81.

[0032] like Figures 1 to 10 As shown, the storage assembly 9 includes a storage box 91 fixedly connected to the other side of the outer surface of the processing box 1. The top of the storage box 91 is fixedly connected to an inlet pipe 92, and a liquid outlet 93 is opened on one side of the bottom of the storage box 91. A liquid outlet pipe 94 is fixedly connected to the corresponding position of the liquid outlet 93. The recycling box 81 and the storage box 91 are both provided with a winding mechanism 10 for supporting and winding the filter cloth 12.

[0033] like Figures 1 to 10 As shown, the winding mechanism 10 includes a second servo motor 109 fixedly connected to the front side of the recycling bin 81. The output end of the second servo motor 109 passes through the recycling bin 81 and is fixedly connected to a winding roller 101. A feeding roller 102 is rotatably connected to the bottom of the recycling bin 81. Both ends of the feeding roller 102 are provided with bracket seats fixedly connected to the recycling bin 81. A main gear 1010 is fixedly connected to the side of the winding roller 101 closest to the second servo motor 109, and the feeding roller 102 is fixedly connected to the side of the second servo motor 109. One end of the main gear 1010 is fixedly connected to a driven gear 1011, which meshes with the main gear 1010. Inside the recycling box 81, near the flow channel 11, there are fixedly connected support cylinders 103 and 108 for supporting the filter cloth 12. Inside the storage box 91, near the flow channel 11, there are fixedly connected support cylinders 104 and 107, while on the side away from the flow channel 11, there are fixedly connected support cylinders 105 and 106.

[0034] To address the problems of high filtration costs and resource waste caused by the difficulty in cleaning and frequent replacement of filter cloths and the inconvenience of recycling filter residues in existing water-reducing agent filtration devices, this new device first introduces a new design. The filter cloth 12 is first led out by the feed roller 102, then passes sequentially around the first support cylinder 103 in the recovery box 81, through the flow channel 11 on the right side of the processing box 1, then through the second support cylinder 104, the third support cylinder 105, the fourth support cylinder 106, and the fifth support cylinder 107, then through the flow channel 11 on the left side of the processing box 1, and finally through the sixth support cylinder 108, before finally being wound onto the take-up roller 101. Each time the filter cloth 12 passes through the flow channel 11, the portion inside the treatment box 1 filters the water-reducing agent. When the second servo motor 109 is started, its output drives the winding roller 101 to rotate. The winding roller 101 drives the unloading roller 102 to rotate synchronously in the opposite direction through the meshing of the main gear 1010 and the driven gear 1011, thereby realizing the continuous winding of the filter cloth 12. The old filter cloth 12 is gradually wound into the winding roller 101, while the unloading roller 102 releases the new filter cloth, so that the filter medium in the treatment box 1 is continuously renewed, avoiding the decrease in filtration efficiency due to filter cloth blockage. Furthermore, during the winding process, solid impurities and gel residues intercepted by the filter cloth 12 will adhere to the surface of the filter cloth. When the filter cloth 12 moves to the storage box 91 area, cleaning solution can be injected into the storage box 91 through the liquid inlet pipe 92 to backwash or soak the filter cloth 12. The waste liquid after cleaning is discharged through the liquid outlet 93 and the liquid outlet pipe 94. During the winding process of the winding roller 101, the fallen waste liquid is guided into the recycling box 85 for centralized collection through the inclined guide plate 84. The transparent plate 82 facilitates observation of the operation of the filter cloth and the collection of impurities inside the recycling box 81. The rear sealing plate 83 is removable, which facilitates maintenance of the inside of the recycling box 81. Through the above operations, This device drives the filter cloth 12 to move continuously through the winding mechanism 10, keeping the filter medium in the treatment box 1 clean at all times. This avoids the problem of frequent shutdowns and replacements due to filter cloth clogging, and greatly improves the continuity of filtration and production efficiency. At the same time, the feeding roller 102 is linked with the winding roller 101, which can load a long length of filter cloth at one time, realizing automatic replacement over a long period of time, reducing manual intervention and waste of filter cloth consumables. Furthermore, the impurities intercepted by the filter cloth move with the filter cloth to the recycling box 81 area, and are collected into the recycling box 85 through cleaning and guidance by the guide plate 84, which facilitates subsequent centralized treatment or resource utilization, and solves the environmental problems caused by the random discharge of waste residue.

[0035] like Figures 1 to 10As shown, the bottom of the storage box 91 is also provided with a rinsing mechanism 13 for cleaning the filter cloth 12. The rinsing mechanism 13 includes a first spray plate 131 fixedly connected to the bottom of the storage box 91. Both sides of the first spray plate 131 are fixedly connected to flow pipes 132. One end of the flow pipe 132 is fixedly connected to a second spray plate 133. A water pump 134 is fixedly connected to the bottom of the storage box 91. One output end of the water pump 134 is provided with a delivery pipe fixedly connected to the first spray plate 131, and the other output end is fixedly connected to a water pumping pipe 135. A first cleaning plate 136 for scraping off dirt is fixedly connected to the bottom of the storage box 91.

[0036] like Figures 1 to 10 As shown, a cleaning mechanism 14 for cleaning the filter cloth 12 is provided on one side of the inner wall of the storage box 91. The cleaning mechanism 14 includes a U-shaped bracket 141 fixedly connected to one side of the inner wall of the storage box 91. A second cleaning plate 142 is hinged inside the U-shaped bracket 141. A connecting plate fixedly connected to the inner wall of the storage box 91 is provided directly above the U-shaped bracket 141. A spring 143 fixedly connected to the second cleaning plate 142 is provided at the bottom of the connecting plate. A fixing plate 144 is fixedly connected to one side of the inner wall of the storage box 91. An electric telescopic rod 145 is fixedly connected to the bottom of the fixing plate 144. An abutment block 146 is fixedly connected to the bottom of the electric telescopic rod 145.

[0037] To address the problem that gel and sticky impurities adhering to the surface of the filter cloth 12 in existing water-reducing agent filtration devices are difficult to remove completely by a single rinsing method, resulting in poor filter cloth regeneration and shortened service life, the following measures are implemented: When the filter cloth 12 moves continuously under the drive of the winding mechanism 10 and passes through the storage box 91, the water pump 134 is activated to extract cleaning fluid through the water pipe 135. The cleaning fluid is then transported to the first spray plate 131 via the delivery pipe, and the first spray plate 131 sprays the cleaning fluid upwards onto the lower surface of the filter cloth 12. Surface; simultaneously, the flow pipes 132 on both sides of the first spray plate 131 divert the cleaning liquid to the second spray plate 133, which sprays the upper surface of the filter cloth 12 from above. Through bidirectional spraying, the cleaning liquid fully penetrates the fiber gaps of the filter cloth 12, softening and washing away embedded gel particles and fine impurities. During the spraying process, the first cleaning plate 136 is used to initially scrape the rinsed filter cloth 12; then the electric telescopic rod 145 extends downwards periodically to push... The contact block 146 moves downward, pressing the upper end of the second cleaning plate 142, causing the second cleaning plate 142 to rotate around the hinge point of the U-shaped bracket 141. This causes the cleaning end of the second cleaning plate 142 to press against the surface of the filter cloth 12 and generate a scraping action. When the electric telescopic rod 145 retracts, the spring 143 pulls the second cleaning plate 142 back to its original position. Through the reciprocating motion of the electric telescopic rod 145, the second cleaning plate 142 intermittently scrapes the surface of the filter cloth 12, removing the softened filter cloth. However, the gel and dirt that have not yet been detached are forcibly peeled off, and the peeled dirt falls to the bottom of the collection box 91 under the action of gravity, and is finally discharged from the liquid outlet pipe 94. During the above operation, the rinsing mechanism 13 provides bidirectional spraying to fully wet and soften the sticky impurities on the filter cloth 12. The second cleaning plate 142 driven by the electric telescopic rod 145 performs intermittent scraping to forcibly peel off the stubborn gel and dirt. The two methods work together to significantly improve the cleaning effect and regeneration quality of the filter cloth.

[0038] A method of using a concrete water-reducing agent filtration device includes the following steps: S1: The concrete water-reducing agent to be filtered is fed into the treatment box 1 through the feed pipe 3; S2: The water-reducing agent is guided into the conical filter 54 after being guided by the liquid guide 62. After preliminary filtration by the conical filter 54, the filtrate enters the bottom of the spherical cylinder 51 through the sieve plate 53 and is then discharged through the discharge pipe 4. S3: During the filtration process of the water-reducing agent, the drive assembly is started to drive the liquid guide hopper 62 to rotate. The liquid guide hopper 62 drives the first scraper 65 to rotate synchronously, so that the first scraper 65 continuously scrapes off the impurities attached to the surface of the conical filter hopper 54. The scraped-off impurities fall into the collection cylinder 55 for collection. S4: At the same time, the ring gear 66 drives the rotating rod 72 to rotate through the support plate 71, so that the screen plate 53 rotates to change the position of the filter hole, and drives the second scraper 74 to move in a circle along the inner wall of the spherical cylinder 51 to scrape off the fine impurities attached to the inner wall of the spherical cylinder 51. S5: Start the second servo motor 109 to drive the winding roller 101 to rotate. Through the meshing of the main gear 1010 and the driven gear 1011, the feeding roller 102 is driven to rotate synchronously in the opposite direction, so that the filter cloth 12 moves continuously and passes through the flow slots 11 on both sides of the processing box 1 to assist in the filtration of the water reducing agent. At the same time, the old filter cloth is wound up and the new filter cloth is released, realizing the continuous renewal of the filter medium. S6: When the filter cloth 12 moves to the storage box 91 area, the water pump 134 is started, and the filter cloth 12 is sprayed from top to bottom in both directions through the No. 1 spray plate 131 and the No. 2 spray plate 133 to soften and wash away the embedded gel particles; at the same time, the electric telescopic rod 145 periodically drives the No. 2 cleaning plate 142 to intermittently scrape the surface of the filter cloth 12, and the peeled dirt is discharged through the liquid outlet pipe 94.

[0039] In use, the concrete water-reducing agent to be filtered first enters the processing tank 1 through the feed pipe 3. Guided by the liquid guide hopper 62, the water-reducing agent flows out from the liquid guide trough 64 and falls evenly onto the conical filter hopper 54. At this time, the water-reducing agent undergoes preliminary filtration on the surface of the conical filter hopper 54, where larger particles of impurities are trapped on the upper surface of the conical filter hopper 54. The filtrate then flows downward into the spherical cylinder 51 through the filter holes inside the conical filter hopper 54. The filtrate flowing into the spherical cylinder 51 undergoes further secondary filtration through the sieve plate 53, and finally... The pure water-reducing agent is discharged from the discharge pipe 4 at the bottom of the treatment tank 1; however, during the above filtration process, the first servo motor 69 is started, which drives the gear plate 67 to rotate via the drive rod 68. The gear plate 67 drives the ring gear 66 to rotate, and the ring gear 66 drives the liquid guide hopper 62 to rotate smoothly under the support of the support bracket 61 and the support plate 63. Since the first scraper 65 is fixedly connected to the bottom of the conical filter hopper 54 near the liquid guide trough 64 and rotates synchronously with the liquid guide hopper 62, the first scraper 65 is used in the filtration of the water-reducing agent. During the process, the filter continuously moves in a circular motion along the surface of the conical filter 54, scraping away solid impurities adhering to the surface of the conical filter 54. The scraped impurities fall into the collection cylinder 55 under the action of gravity and are collected, thus avoiding the accumulation of impurities near the filter holes for a long time and causing blockage. At the same time, when the ring gear 66 rotates, it drives the rotating rod 72 to rotate synchronously through the support plate 71 fixedly connected inside it. Since the screen plate 53 is fixedly connected to the rotating rod 72, the screen plate 53 rotates accordingly, causing the filter holes on the screen plate 53 to continuously change position, avoiding impurities from being removed. The impurities continuously accumulate in the same position, and the top of the rotating rod 72 is equipped with a limiting seat 73, which is fixedly connected to the inner wall of the processing box 1 to ensure that the rotating rod 72 rotates smoothly without axial movement. Furthermore, since a second scraper 74 is fixedly connected to the rotating rod 72, and the second scraper 74 is crescent-shaped, its cleaning end abuts against the inner wall of the spherical cylinder 51. As the rotating rod 72 rotates, the second scraper 74 moves circumferentially along the inner wall of the spherical cylinder 51, scraping away the fine impurities adhering to the inner wall of the spherical cylinder 51, preventing impurities from accumulating on the inner wall and re-mixing into the filtrate. Through the continuous rotation and cleaning of the first scraper 65 and the second scraper 74 during the filtration process, separate cleaning after machine shutdown is unnecessary, achieving simultaneous cleaning and filtration.Next, the filter cloth 12 is led out by the feed roller 102, passes sequentially around the first support cylinder 103 in the recycling box 81, passes through the flow channel 11 on the right side of the processing box 1, then passes through the second support cylinder 104, the third support cylinder 105, the fourth support cylinder 106, and the fifth support cylinder 107 in the storage box 91, then passes through the flow channel 11 on the left side of the processing box 1, and then passes through the sixth support cylinder 108, finally being wound onto the take-up roller 101. Each time the filter cloth 12 passes through the flow channel 11, the portion inside the processing box 1... The water-reducing agent is used for auxiliary filtration. When the second servo motor 109 starts, its output drives the winding roller 101 to rotate. The winding roller 101 drives the unloading roller 102 to rotate synchronously in the opposite direction through the meshing of the main gear 1010 and the driven gear 1011, thereby realizing the continuous winding of the filter cloth 12. The old filter cloth 12 is gradually wound up to the winding roller 101, while the unloading roller 102 releases new filter cloth, so that the filter medium in the treatment box 1 is continuously renewed, avoiding the decrease in filtration efficiency due to filter cloth blockage. Furthermore, in order to more thoroughly... To clean the gel and sticky impurities adhering to the filter cloth 12, as the filter cloth 12 moves continuously and passes through the storage box 91, the water pump 134 is activated, and the cleaning solution is drawn through the water pipe 135 and transported to the first spray plate 131 through the delivery pipe. The first spray plate 131 sprays the cleaning solution upward onto the lower surface of the filter cloth 12. At the same time, the flow pipes 132 on both sides of the first spray plate 131 divert the cleaning solution to the second spray plate 133, which sprays the upper surface of the filter cloth 12 from above. The bidirectional spraying process allows the cleaning solution to fully penetrate the fiber gaps of the filter cloth 12, softening and washing away embedded gel particles and fine impurities. During the spraying process, the first cleaning plate 136 performs preliminary scraping on the rinsed filter cloth 12. Simultaneously, the electric telescopic rod 145 periodically extends downwards, pushing the contact block 146 downwards. The contact block 146 presses against the upper end of the second cleaning plate 142, causing the second cleaning plate 142 to rotate around the hinge point of the U-shaped bracket 141, thereby pressing its cleaning end against the surface of the filter cloth 12 and generating a scraping action. When the electric telescopic rod 145 retracts, the spring 143 pulls the second cleaning plate 142 back to its original position. Through the reciprocating motion of the electric telescopic rod 145, the second cleaning plate 142 intermittently scrapes the surface of the filter cloth 12, forcibly peeling off the gel and dirt that have been softened by the spraying but have not yet detached. The peeled-off dirt falls to the bottom of the collection box 91 under gravity and is finally discharged from the outlet pipe 94.
