Description

Technical Field

[0001] This utility model relates to the field of micro-flocculation filtration, specifically a micro-flocculation filtration device. Background Technology

[0002] In the field of water treatment, microflocculation filtration devices are widely used in drinking water purification, industrial circulating water purification, and other scenarios due to their high efficiency and energy saving. During the microflocculation filtration process, the effective treatment of flocs and the improvement of filtration efficiency directly affect the overall operation of the device and the quality of the effluent.

[0003] Currently, traditional micro-flocculation filtration devices suffer from numerous problems during operation. On the one hand, after the filter plate intercepts flocs, a large amount of flocs adhere to the top of the filter plate. As the operating time increases, these flocs gradually accumulate, not only clogging the filter holes and affecting the filtration effect, but also lacking convenient and efficient floc scraping and discharge structures. Often, manual disassembly of the filter plate is required for cleaning, which is cumbersome, time-consuming, and labor-intensive, severely impacting the continuous operating efficiency of the device. On the other hand, most existing micro-flocculation filtration devices rely on natural pressure for filtration, resulting in slow filtration speeds that cannot meet the filtration efficiency requirements of large-scale water treatment. Therefore, it is necessary to design a micro-flocculation filtration device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a micro-flocculation filtration device to solve the problems mentioned in the background art.

The bottom end of the rotating rod passes through the filter frame and extends into the interior of the filter frame. A turntable is fixedly mounted on the bottom end of the rotating rod. A sliding rod is fixedly mounted on the bottom of the turntable. A scraper is provided on the top of the filter plate. The bottom end of the sliding rod passes through the scraper and extends into the interior of the scraper. A movable groove is provided on the top of the scraper to cooperate with the sliding rod.

[0007] Preferably, an airbag is fixedly installed on the left side of the filter frame, an air inlet pipe is connected to the rear of the left side of the airbag, a first one-way valve is provided on the surface of the air inlet pipe, an air delivery pipe is connected to the front of the left side of the airbag, a second one-way valve is provided on the surface of the air delivery pipe, and one end of the second one-way valve is connected to the left side of the filter frame.

[0008] Preferably, an L-shaped plate is fixedly installed on the left side of the airbag, and a rotating rod that cooperates with the L-shaped plate is fixedly installed at the rear of the rotating rod.

[0009] Preferably, the front and rear parts of the L-shaped plate are both fixedly mounted with sleeves by brackets, and a spring is welded to the left side of the inner cavity of the sleeve.

[0010] Preferably, a support rod is welded to the right end of the spring.

[0011] Preferably, the right end of the support rod is fixedly connected to the left side of the filter frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This micro-flocculation filtration device delivers wastewater mixed with flocculant into the filter frame through the feed pipe. After entering the filter frame, the water can be filtered by the filter plate. During the filtration process, the motor can be started, which drives the rotating rod to rotate. The rotating rod drives the turntable to rotate, and the turntable drives the sliding rod to rotate. The rotation of the sliding rod drives the scraper to move back and forth through the movable groove, thereby achieving the effect of scraping off the flocs on the top of the filter plate. When it is necessary to discharge the flocs, the first solenoid valve on the surface of the drain pipe can be opened to allow the flocs to be discharged through the drain pipe.

[0014] 2. This micro-flocculation filtration device uses a motor to rotate a rotating rod, which in turn rotates a keystone. This keystone contacts an L-shaped plate, stretching the air bladder. Air enters the air bladder through the air inlet pipe. When the keystone is not in contact with the L-shaped plate, a spring pulls the L-shaped plate to the right, allowing air from the air bladder to be delivered to the filter frame through the air supply pipe. This pressurizes the filter frame, increasing its filtration efficiency for wastewater. Attached Figure Description

A turntable 8 is fixedly mounted on the bottom end of the rotating rod 7, and a sliding rod 9 is fixedly mounted on the bottom of the turntable 8. A scraper 10 is provided on the top of the filter plate 3. The bottom end of the sliding rod 9 passes through the scraper 10 and extends into its interior. A movable groove 11, which cooperates with the sliding rod 9, is provided on the top of the scraper 10. The motor 6... The wastewater mixed with flocculant is transported from the feed pipe 12 to the filter frame 2. After entering the filter frame 2, the water can be filtered by the filter plate 3. During the filtration process, the motor 6 can be started. The motor 6 starts and drives the rotating rod 7 to rotate. The rotating rod 7 drives the turntable 8 to rotate. The turntable 8 drives the sliding rod 9 to rotate. The rotation of the sliding rod 9 drives the scraper 10 to move back and forth through the movable groove 11, thereby achieving the effect of scraping off the flocs on the top of the filter plate 3. When it is necessary to discharge the flocs, the first solenoid valve 5 on the surface of the drain pipe 4 can be opened to allow the flocs to be discharged through the drain pipe 4.

[0024] Specifically, an airbag 16 is fixedly installed on the left side of the filter frame 2. An air inlet pipe 18 is connected to the rear of the left side of the airbag 16. A first one-way valve 19 is provided on the surface of the air inlet pipe 18. An air delivery pipe 20 is connected to the front of the left side of the airbag 16. A second one-way valve 21 is provided on the surface of the air delivery pipe 20. One end of the second one-way valve 21 is connected to the left side of the filter frame 2.

By starting the motor 6, the motor 6 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the rotating rod 22 to rotate. The rotating rod 22 rotates and contacts the L-shaped plate 17, causing the airbag 16 to be stretched. At this time, air enters the airbag 16 through the air inlet pipe 18. When the rotating rod 22 is not in contact with the L-shaped plate 17, the spring 24 can pull the L-shaped plate 17 to the right through its elastic force. At this time, the air in the airbag 16 can be transported to the filter frame 2 through the air supply pipe 20, achieving the effect of pressurizing the filter frame 2. The increased pressure in the filter frame 2 can improve the filtration efficiency of sewage.

[0025] Working Principle: This utility model is a micro-flocculation filtration device. Wastewater mixed with flocculant is transported from the feed pipe 12 into the filter frame 2. After entering the filter frame 2, the water is filtered by the filter plate 3. During the filtration process, the motor 6 can be started, driving the rotating rod 7 to rotate. The rotating rod 7 drives the turntable 8 to rotate, which in turn drives the sliding rod 9 to rotate. The rotation of the sliding rod 9 drives the scraper 10 to move back and forth through the movable groove 11, thereby achieving the effect of scraping away the flocs on the top of the filter plate 3. When it is necessary to discharge the flocs, the surface of the drain pipe 4 can be opened. The first solenoid valve 5 allows the flocs to be discharged through the sewage pipe 4. At the same time, the rotating rod 7 rotates, driving the rotating rod 22 to rotate. The rotating rod 22 rotates and contacts the L-shaped plate 17, stretching the airbag 16. At this time, air enters the airbag 16 through the air inlet pipe 18. When the rotating rod 22 is not in contact with the L-shaped plate 17, the spring 24 can pull the L-shaped plate 17 to the right through its elastic force. At this time, the air in the airbag 16 can be transported to the filter frame 2 through the air supply pipe 20, achieving the effect of pressurizing the filter frame 2. The increased pressure in the filter frame 2 can improve the filtration efficiency of sewage.
