DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0041] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0042] Reference Figure 1-Figure 13 As shown, a separation device for sewage treatment, the separation device comprises: a feed box 100, a filter box 200 connected to the feed box 100 through a feed pipe 101 for filtering water and sludge in the sewage, and a flocculation box 300 connected to the filter box 200 for flocculating and filtering the filtered sewage; wherein the feed box 100 is provided with a crushing piece for crushing impurities in the sewage, the filter box 200 is fixedly provided with an inclined first filter plate 201 and a cleaning mechanism 600 for cleaning the first filter plate 201 to prevent clogging, and the side of the filter box 200 is also fixedly connected with a recovery cylinder 400 for collecting the filtered sludge and a deodorizing box 500 for removing odor in the sewage during filtration.

[0043] In the feed box 100, the sewage is pre-treated by a crushing element, which effectively breaks up large impurities and solid particles in the sewage, reducing obstacles to the subsequent filtration process. The pre-treated sewage flows into the filter box 200 through the feed pipe 101. In the filter box 200, the sewage first contacts the inclined first filter plate 201. Due to the effect of gravity and the tilt angle, most of the suspended matter, particulate matter and sludge in the sewage are trapped on the first filter plate 201, while the relatively clear water flows into the space below through the first filter plate 201. In order to prevent the first filter plate 201 from being blocked, the cleaning mechanism 600 will clean the first filter plate 201 when the equipment is running. At the same time, the sludge generated during the filtration process slides down along the tilted first filter plate 201 and finally falls into the recovery barrel 400 fixedly connected to the side of the filter box 200, so as to realize the centralized recovery and treatment of the sludge. While the sewage is being filtered, the deodorizing box 500 starts to work, removes the odor emitted from the sewage by adsorption, improves the working environment and reduces environmental pollution. The sewage after preliminary filtration then flows into the flocculation box 300 connected to the filter box 200 through a pipeline. In the flocculation box 300, an appropriate amount of flocculant is added to the sewage to aggregate the residual tiny suspended matter and colloidal particles into larger flocs, which is convenient for the subsequent solid-liquid separation. After flocculation and filtration, the clarity and water quality of the sewage are significantly improved.

[0044] Reference Figure 7 As shown, the cleaning mechanism 600 includes: a movable rod 602, a cleaning plate 604, a scraper 605 and a first driving member; wherein, the inner wall of the filter box 200 is provided with a limiting groove 601 parallel to the first filter plate 201 for the movable rod 602 to slide, an elastic shaft 603 is fixedly provided on the movable rod 602, and a cleaning plate 604 in contact with the surface of the first filter plate 201 is fixedly provided on the bottom surface of the elastic shaft 603, the inner wall of the filter box 200 is fixedly provided with a scraper 605 for cleaning the surface of the cleaning plate 604, and the outer wall of the filter box 200 is fixedly provided with a first driving member for driving the movable rod 602 to move so that the cleaning plate 604 cleans the surface of the first filter plate 201.

[0045] When in use, the first driving member drives the movable rod 602 to slide in the limiting groove 601, driving the elastic shaft 603 and the cleaning plate 604 to move along the surface of the first filter plate 201. During the movement of the cleaning plate 604, its edge or bottom scrapes the surface of the first filter plate 201 to scrape off the attached sludge and particulate matter. During the movement of the cleaning plate 604, the scraper 605 fixed on the inner wall contacts the surface of the cleaning plate 604 to further scrape off the sludge and impurities accumulated on the cleaning plate 604, ensuring that the cleaning plate 604 will not bring the sludge back to the surface of the first filter plate 201 again when returning to the initial position. The cleaning mechanism 600 realizes automatic cleaning of the first filter plate 201, reduces manual intervention, and improves work efficiency and equipment reliability.

[0046] Reference Figure 7 As shown, the first driving member includes: an electric telescopic rod 606, a rack 607, a gear 608 and a rotation limit rod 609; wherein, the electric telescopic rod 606 is fixedly arranged on the outer wall of the filter box 200 and the output end is horizontally fixedly connected with the rack 607, the inner wall of the filter box 200 is rotatably provided with a rotation limit rod 609, the movable rod 602 is slidably sleeved in the rotation limit rod 609, the rotation axis of the rotation limit rod 609 is fixedly connected to the gear 608, and the rack 607 is meshed with the gear 608.

[0047] In the above scheme, when the first filter plate 201 needs to be cleaned, the electric telescopic rod 606 starts to work and gradually extends its output end. As the output end of the electric telescopic rod 606 extends, the rack 607 moves accordingly and meshes with the gear 608. The rotating shaft of the gear 608 is fixedly connected to the rotation limit rod 609, so the rotation of the gear 608 will drive the rotation limit rod 609 to rotate together. Since the movable rod 602 is slidably sleeved in the rotation limit rod 609 and is limited by the limit groove 601, when the rotation limit rod 609 rotates, the movable rod 602 will slide along the direction of the limit groove 601, thereby driving the elastic shaft 603 and the cleaning plate 604 to move together, so that the cleaning plate 604 contacts and scrapes the surface of the first filter plate 201. During the movement, the cleaning plate 604 scrapes off the sludge and impurities on the surface of the first filter plate 201. When the electric telescopic rod 606 reaches the preset extended position, it begins to gradually retract, and through the meshing transmission of the rack 607 and the gear 608, the rotation limit rod 609 is driven to rotate in the opposite direction, so that the movable rod 602 and the cleaning plate 604 return to the initial position.

[0048] Reference Figure 8-Figure 9As shown, the recovery drum 400 is connected to the filter box 200 through a feed port 407 and a discharge port 406 for discharging mud is fixedly connected to the side wall. A first rotating shaft 401 rotates through the top surface of the recovery drum 400. A section of the first rotating shaft 401 located inside the recovery drum 400 is fixedly provided with a spiral blade 405. The first rotating shaft 401 is provided with a second driving member for driving the first rotating shaft 401 to rotate.

[0049] When in use, the sludge filtered by the first filter plate 201 will slide down along the inclined filter plate, and finally enter the recovery barrel 400 through the feed port 407. The second driving member starts to work, driving the first rotating shaft 401 to rotate in the top surface of the recovery barrel 400. As the first rotating shaft 401 rotates, the spiral blade 405 fixed thereon also starts to rotate. The rotation of the spiral blade 405 transports the sludge at the bottom of the recovery barrel 400 upward, and gradually moves toward the discharge port 406 along the path of the spiral blade 405. Under the push of the spiral blade 405, the sludge is finally transported to the discharge port 406 and discharged from the recovery barrel 400 from the port, realizing the automatic collection and transportation of the sludge, reducing manual intervention, and improving work efficiency.

[0050] Reference Fig. 9 As shown, the second driving member includes: a driven bevel gear 402 and a driving bevel gear 403; the driven bevel gear 402 is fixedly arranged at the top end of the first rotating shaft 401, and the side wall of the feed box 100 is rotatably provided with a driving bevel gear 403, the driving bevel gear 403 is meshed with the driven bevel gear 402, and the driving bevel gear 403 is connected to the output shaft of the driving motor 103 in the crushing member through the first transmission belt 404.

[0051] When the sewage treatment separation device starts to work, the driving motor 103 located in the feed box 100 is first started. The output shaft of the driving motor 103 starts to rotate, and the output shaft of the driving motor 103 is connected to the driving bevel gear 403 through the first transmission belt 404. As the driving motor 103 rotates, the first transmission belt 404 starts to drive, driving the driving bevel gear 403 to rotate on the side wall of the feed box 100, and the driving bevel gear 403 is meshed with the driven bevel gear 402 located at the top of the recovery tube 400. When the driving bevel gear 403 rotates, the driven bevel gear 402 and the first rotating shaft 401 fixedly connected thereto are driven to rotate in the recovery tube 400 through the meshing transmission of the bevel gears. As the first rotating shaft 401 rotates, the spiral blade 405 fixed thereon also starts to rotate. Through the transmission connection between the first transmission belt 404 and the bevel gear, the driving motor 103 drives the spiral blade 405, and there is no need to provide an additional power source for sludge transportation, thereby improving energy utilization efficiency.

[0052] Reference Fig.11- and 13, the flocculation box 300 is provided with a centrifugal part for quickly separating the filtered sewage from mud and water again and a flocculation mechanism 800 located below the centrifugal part for flocculating the separated water; wherein the centrifugal part comprises: a second rotating shaft 301 and a filter cartridge 302, the filter cartridge 302 is coaxially slidably sleeved in the flocculation box 300, the side wall of the flocculation box 300 is connected with a discharge pipe 304 for discharging the water after flocculation, the top of the flocculation box 300 is rotated through by the second rotating shaft 301, the filter cartridge 302 is fixedly sleeved on the second rotating shaft 301, the second rotating shaft 301 is connected to the first rotating shaft 401 through a second transmission belt 303, and the inner wall of the flocculation box 300 is also fixedly provided with a vibration mechanism 700 for driving the filter cartridge 302 to vibrate up and down along the second rotating shaft 301.

[0053] In the above scheme, the sewage entering the flocculation box 300 first encounters the centrifugal member, that is, the filter cartridge 302 coaxially slidably sleeved in the flocculation box 300. At this time, since the second rotating shaft 301 and the first rotating shaft 401 are connected by the second transmission belt 303, and the first rotating shaft 401 is driven to rotate by the second driving member, the second rotating shaft 301 and the filter cartridge 302 fixedly sleeved thereon will also rotate synchronously, and the centrifugal force generated by the rotation causes the tiny particles and suspended matter in the sewage to gather on the wall surface of the filter cartridge 302, thereby achieving mud and water separation. At the same time, the vibration mechanism 700 starts to work, driving the filter cartridge 302 to vibrate up and down along the second rotating shaft 301. This vibration helps to further promote the sedimentation and separation of particles in the sewage, improve the effect of centrifugal separation, and prevent the filter cartridge 302 from being blocked; the water after centrifugal separation enters the flocculation mechanism 800. In the flocculation mechanism 800 , by adding flocculants and stirring, tiny suspended particles in the water are aggregated into larger flocs, which are convenient for subsequent sedimentation or filtration treatment. The water after flocculation is discharged through the discharge pipe 304 connected to the side wall of the flocculation box 300 .

[0054] Reference Fig.12 As shown, the vibration mechanism 700 includes: a fixing ring 701, a lower protrusion 702 and a spring 705; wherein the fixing ring 701 is coaxially fixed to the inner wall of the flocculation box 300, the upper surface of the fixing ring 701 is provided with a plurality of lower protrusions 702 at intervals along its circumferential direction, the bottom surface of the filter cartridge 302 is fixed with upper protrusions 703 used in conjunction with the lower protrusions 702 at intervals, the surface of the second rotating shaft 301 is provided with a plurality of slide grooves 704 at intervals, the filter cartridge 302 is slidably arranged in the slide groove 704 through a slider 706, a spring 705 is fixed in the slide groove 704, and the top end of the spring 705 is arranged in contact with the bottom surface of the slider 706.

[0055] When the second rotating shaft 301 is driven to rotate by the transmission system, the filter cartridge 302 fixedly mounted thereon also rotates accordingly. At this time, due to the action of centrifugal force, the muddy water in the sewage begins to separate. During the centrifugal separation process, due to factors such as the imbalance of rotation and water flow power, the filter cartridge 302 will generate a certain vibration. At the same time, the spring 705 acts as an elastic element, and its existence enables the filter cartridge 302 to perform a slight up and down vibration in the vertical direction while rotating along the second rotating shaft 301. This up and down vibration is further enhanced by the intermittent contact between the upper protrusion 703 and the lower protrusion 702. When the bottom surface of the filter cartridge 302 vibrates to contact with the lower protrusion 702, a short impact force is generated, which helps to promote the sedimentation and separation of particles in the sewage. With the continuous centrifugal separation and vibration, the muddy water in the sewage is effectively separated, and the clear water enters the flocculation mechanism 800 for subsequent treatment.

[0056] Reference Fig.13 As shown, the flocculation mechanism 800 includes: a bidirectional screw 801, a stirring rod 802 and a second filter plate 804; wherein, the bottom surface of the second rotating shaft 301 is fixedly connected with the bidirectional screw 801, the stirring rod 802 is fixedly provided on the bidirectional screw 801 near the filter cylinder 302, and the second rotating shaft 301 is also threadedly sleeved with a second filter plate 804, the bottom surface of the flocculation box 300 is fixedly provided with a limit rod 803, and the second filter plate 804 is slidably sleeved on the limit rod 803.

[0057] In the above scheme, after the preliminary mud and water separation by the filter cartridge 302, relatively clear water still containing tiny suspended particles enters the bottom area of ​​the flocculation box 300. As the second rotating shaft 301 continues to rotate, the bidirectional screw 801 fixedly connected to its bottom surface also starts to rotate. When the bidirectional screw 801 rotates, the stirring rod 802 thereon rotates accordingly to stir the water at the bottom of the flocculation box 300. The rotation of the second rotating shaft 301 also drives the second filter plate 804 to slide on the limit rod 803 through the threaded connection. As the second filter plate 804 moves up and down, it can preliminarily intercept and filter the large particle flocs formed during the flocculation process.

[0058] Reference Figure 4-Figure 5 As shown, the crushing part includes: a driving motor 103 and crushing blades 104; a plurality of groups of crushing blades 104 are rotatably arranged in parallel in the feed box 100, and a driving motor 103 is fixedly arranged on the side wall of the feed box 100. The output shaft of the driving motor 103 is horizontally arranged and the end is fixedly connected to one group of crushing blades 104 through a shaft coupling, and every two groups of crushing blades 104 are connected through a third transmission belt 102.

[0059] When the sewage treatment separation device starts to work, the drive motor 103 located on the side wall of the feed box 100 is started first. The output shaft of the drive motor 103 starts to rotate, and transmits the rotational power to a group of crushing blades 104 fixedly connected thereto through the shaft coupling. Since every two groups of crushing blades 104 are connected by the third transmission belt 102, when the first group of crushing blades 104 starts to rotate, the rotational power will be transmitted to the subsequent crushing blade groups in sequence through the transmission belt, so that all crushing blades 104 can rotate synchronously. With the rotation of the crushing blades 104, the large impurities and solid particles in the sewage entering the feed box 100 are effectively crushed into smaller particles. This crushing action helps the separation and filtration of mud and water in the subsequent treatment steps, realizes the rapid crushing of large impurities and solid particles in the sewage, provides better conditions for the subsequent treatment steps, and thus improves the overall treatment efficiency.

[0060] Reference Figure 6 As shown, the deodorizing box 500 is connected to the filter box 200 via a connecting pipe 501, and an air outlet 503 is provided on its side wall for discharging air. A fan 502 is fixedly provided in the middle section of the connecting pipe 501, and a plurality of groups of detachable activated carbon plates 504 are fixedly provided at intervals inside the deodorizing box 500.

[0061] During the sewage treatment process, the sewage that has been initially filtered enters the filter box 200 for further filtering. At the same time, as the sewage flows and is treated, certain odors and harmful gases will be generated. In order to treat these odors and harmful gases, the deodorizing box 500 is connected to the filter box 200 through the connecting pipe 501. When the fan 502 is started, the suction force generated by it introduces the odors and harmful gases generated in the filter box 200 into the deodorizing box 500 through the connecting pipe 501. The gas entering the deodorizing box 500 first contacts with multiple groups of detachable activated carbon plates 504. The activated carbon plates 504 have a strong adsorption capacity and can effectively adsorb and remove odor molecules and harmful substances in the gas, thereby achieving gas purification. The purified gas treated by the activated carbon plates 504 is discharged from the outside of the device through the air outlet 503 of the deodorizing box 500, reducing pollution to the surrounding environment.

[0062] In summary, the present invention provides a separation device for sewage treatment. When in use, the pre-treated sewage flows into the filter box 200 through the feed pipe 101. In the filter box 200, the sewage first contacts the inclined first filter plate 201. Due to the effects of gravity and the inclination angle, most of the suspended matter, particulate matter and sludge in the sewage are retained on the first filter plate 201, while the relatively clear water flows into the space below through the first filter plate 201. When the first filter plate 201 needs to be cleaned, the electric telescopic rod 606 starts to work, and the rack 607 moves accordingly. The rotating shaft of the gear 608 is fixedly connected to the rotating limit rod 609, so that the rotation of the gear 608 will drive the rotating limit rod 609 to rotate together, and the movable rod 602 will slide along the direction of the limit groove 601, thereby driving the elastic shaft 603 and the cleaning plate 604 to move together. , so that the cleaning plate 604 contacts and scrapes the surface of the first filter plate 201. The cleaning plate 604 scrapes off the sludge and impurities on the surface of the first filter plate 201 during the movement. The sludge generated during the filtration process slides down along the inclined first filter plate 201, and finally falls into the recovery barrel 400 fixedly connected to the side of the filter box 200, so as to realize the centralized recovery and treatment of the sludge. While the sewage is being filtered, the deodorizing box 500 starts to work, removes the odor emitted from the sewage by adsorption, improves the working environment and reduces environmental pollution, and the sewage after preliminary filtration then flows into the flocculation box 300 connected to the filter box 200 through a pipeline.
