Abstract
Description
Technical Field
[0001] This utility model relates to the field of activated sludge filtration and treatment technology, specifically an activated sludge dewatering and filtration device. Background Technology
[0002] The activated sludge process is an aerobic treatment method that uses suspended microbial flocs to treat organic wastewater. However, when treating waste activated sludge, since it contains a certain amount of water and impurities, a filtration device is needed to dewater and filter the activated sludge.
[0003] However, in some existing dewatering and filtration devices, the filter screen is often placed inside the filtration device, which makes it inconvenient to remove the filter screen after use and makes it difficult to clean, thus reducing the practicality of the filtration device. Therefore, an activated sludge dewatering and filtration device is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An activated sludge dewatering and filtration device of this utility model includes a base, a drain bucket fixedly connected to the outer side of the base, a first motor fixedly connected to the outer side of the base, a water-spinning bucket fixedly connected to the output end of the first motor, a filter groove formed on the surface of the water-spinning bucket, a hydraulic cylinder fixedly connected to the outer side of the base, a cover plate fixedly connected to the output end of the hydraulic cylinder, a rotating plate rotatably connected to the inner side of the cover plate, a locking block fixedly connected to the outer side of the rotating plate, a locking plate slidably connected to the outer side of the locking block, and a filter screen fixedly connected to the outer side of the locking plate; this step involves setting up a water-spinning bucket, a cover plate, and a rotating plate. The system consists of a locking block, a locking plate, and a filter screen. During operation, a hydraulic cylinder lowers the cover and rotating plate, sealing the opening of the water-spinning tank. The rotating plate then lowers the locking block, locking plate, and filter screen, inserting the filter screen into the filter tank. Activated sludge is poured into the water-spinning tank through the opening of the rotating plate. The first motor drives the water-spinning tank and filter screen to rotate, allowing the water contained in the activated sludge to be filtered through the filter screen and ejected into the drain tank. Wastewater is then discharged through the drain tank's pipe. After filtration, the rotating plate is raised, causing the filter screen to rise. Pulling the locking plate separates the locking block, facilitating filter screen removal and cleaning, thus improving the ease of cleaning the device.
[0006] Preferably, a lifting rod is rotatably connected to the outer side of the rotating plate, and a lifting plate is rotatably connected to the outer side of the lifting rod. A limiting strip is fixedly connected to the outer side of the sling-off bucket, and the limiting strip and the lifting plate work together. This step, by setting up the lifting rod, the lifting plate, and the limiting strip, ensures that when the activated sludge is placed inside the sling-off bucket, the lifting plate supports the activated sludge. When the sling-off bucket rotates, it drives the lifting plate to rotate, which in turn drives the activated sludge to be spun around. After use, the rotating plate drives the lifting rod and the lifting plate to rise, allowing the lifting plate to lift the activated sludge from inside the sling-off bucket for easy removal of the dewatered sludge, thus improving the ease of use of the device.
[0007] Preferably, an inclined ring is fixedly connected to the upper side of the base, and the inclined ring is used in conjunction with the drain bucket. This step, by setting the inclined ring, allows the wastewater to be guided by the inclined surface of the inclined ring after it is thrown out of the drain bucket, so that it can be quickly discharged from the pipe of the drain bucket, thereby improving the convenience of using the device.
[0008] Preferably, a second motor is fixedly connected to the outer side of the cover plate, and the output end of the second motor is fixedly connected to the lifting rod. A stirring blade is fixedly connected to the outer side of the lifting rod. This step, by setting the second motor and the stirring blade, allows the lifting rod to rotate when the slinging bucket drives the activated sludge to dewater. The lifting rod then drives the stirring blade to rotate, and the stirring blade agitates the activated sludge, making it easier to move the activated sludge in different positions closer to the filter screen for filtration, thus improving the convenience of dewatering the device.
[0009] Preferably, a blocking block is rotatably connected to the inner side of the rotating plate, and a magnetic ring is fixedly connected to the outer side of the blocking block. The magnetic ring and the rotating plate are fixedly connected. This step, by setting the blocking block and the magnetic ring, allows the blocking block to be fixed by inserting it into the opening on the surface of the rotating plate after the activated sludge is poured into the inside of the sling-off bucket. The magnetic ring then adheres the blocking block to the outer side of the rotating plate, thereby further sealing the rotating plate and improving the sealing performance of the device.
[0010] Preferably, a mounting plate is fixedly connected to the outer side of the base, and the surface of the mounting plate is provided with a mounting groove. By setting the mounting plate and the mounting groove, the device can be installed and fixed by screwing screws into the mounting groove and the mounting location before use, which makes the device more stable in position during use and improves the stability of the device during use.
[0011] The advantages of this utility model are:
[0012] 1. This utility model, by setting up a water-spinning bucket, a cover plate, a rotating plate, a locking block, a locking plate, and a filter screen, in use, the cover plate and the rotating plate are driven to move down by a hydraulic cylinder, so that the cover plate and the rotating plate block the opening of the water-spinning bucket. The rotating plate drives the locking block, the locking plate, and the filter screen to move down, so that the filter screen is inserted into the filter tank. Activated sludge is poured into the water-spinning bucket through the opening of the rotating plate and rotated. The first motor drives the water-spinning bucket and the filter screen to rotate, so that the water contained in the activated sludge is filtered through the filter screen and thrown out into the drain bucket. The sewage is discharged through the pipe of the drain bucket. After filtration, the rotating plate is raised, so that the rotating plate drives the filter screen to rise. By pulling the locking plate and the locking block, the filter screen can be easily removed and cleaned, which improves the convenience of cleaning the device.
[0013] 2. This utility model, by setting up a lifting rod, a lifting plate, and a limiting strip, allows the activated sludge to be supported by the lifting plate when placed inside the slinging bucket. When the slinging bucket rotates, it drives the lifting plate to rotate, which in turn drives the activated sludge to be swung. After use, the rotating plate drives the lifting rod and lifting plate to rise, allowing the lifting plate to lift the activated sludge from inside the slinging bucket for easy removal of the dewatered sludge, thus improving the convenience of using the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Specific implementation examples are given below.
[0023] Please see Figures 1 to 5 As shown, an activated sludge dewatering and filtration device includes a base 1, a drain tank 2 fixedly connected to the outside of the base 1, a first motor 3 fixedly connected to the outside of the base 1, a water-spinning tank 4 fixedly connected to the output end of the first motor 3, a filter groove 5 formed on the surface of the water-spinning tank 4, a hydraulic cylinder 6 fixedly connected to the outside of the base 1, a cover plate 7 fixedly connected to the output end of the hydraulic cylinder 6, a rotating plate 8 rotatably connected to the inside of the cover plate 7, a locking block 9 fixedly connected to the outside of the rotating plate 8, a locking plate 10 slidably connected to the outside of the locking block 9, and a filter screen 11 fixedly connected to the outside of the locking plate 10. This step, by setting up the water-spinning tank 4, cover plate 7, rotating plate 8, locking block 9, locking plate 10, and filter screen 11, allows for efficient operation. The hydraulic cylinder 6 drives the cover plate 7 and the rotating plate 8 to move down, so that the cover plate 7 and the rotating plate 8 block and seal the opening of the water-spinning tank 4. The rotating plate 8 drives the locking block 9, the locking plate 10 and the filter screen 11 to move down, so that the filter screen 11 is inserted into the inside of the filter tank 5. The activated sludge is poured into the water-spinning tank 4 through the opening of the rotating plate 8 and rotated. The first motor 3 drives the water-spinning tank 4 and the filter screen 11 to rotate, so that the water contained in the activated sludge is filtered through the filter screen 11 and thrown out into the inside of the drain tank 2. The sewage is discharged through the pipe of the drain tank 2. After filtration, the rotating plate 8 is raised, so that the rotating plate 8 drives the filter screen 11 to rise. By pulling the locking plate 10 and the locking block 9, the filter screen 11 can be easily removed and cleaned, which improves the convenience of cleaning the device.
[0024] Furthermore, such as Figure 1As shown, a lifting rod 12 is rotatably connected to the outside of the rotating plate 8, and a lifting plate 13 is rotatably connected to the outside of the lifting rod 12. A limiting strip 14 is fixedly connected to the outside of the water-spinning bucket 4. The limiting strip 14 and the lifting plate 13 work together. This step, by setting up the lifting rod 12, the lifting plate 13, and the limiting strip 14, ensures that when the activated sludge is placed inside the water-spinning bucket 4, the lifting plate 13 supports the activated sludge. When the water-spinning bucket 4 rotates, it drives the lifting plate 13 to rotate, which in turn drives the activated sludge to be spun around. After use, the rotating plate 8 drives the lifting rod 12 and the lifting plate 13 to rise, allowing the lifting plate 13 to lift the activated sludge from inside the water-spinning bucket 4, facilitating the removal of the dewatered sludge and improving the ease of use of the device.
[0025] Furthermore, such as Figure 1 As shown, a slanted ring 15 is fixedly connected to the upper side of the base 1. The slanted ring 15 is used in conjunction with the drain bucket 2. By setting the slanted ring 15, the sewage is guided by the slanted surface of the slanted ring 15 after being thrown out of the water-throwing bucket 4, so that it can be quickly discharged from the pipe of the drain bucket 2, which improves the convenience of using the device.
[0026] Furthermore, such as Figure 1 As shown, a second motor 16 is fixedly connected to the outer side of the cover plate 7. The output end of the second motor 16 is fixedly connected to the lifting rod 12. An agitator 21 is fixedly connected to the outer side of the lifting rod 12. In this step, by setting the second motor 16 and the agitator 21, when the water-spinning tank 4 drives the activated sludge to spin for dewatering, the second motor 16 can drive the lifting rod 12 to rotate, and the lifting rod 12 can drive the agitator 21 to rotate. The agitator 21 can stir the activated sludge, so as to adjust the activated sludge in different positions to move closer to the filter screen 11 for filtration, thereby improving the convenience of dewatering of the device.
[0027] Furthermore, such as Figure 1 and Figure 2 As shown, a blocking block 17 is rotatably connected to the inner side of the rotating plate 8, and a magnetic ring 18 is fixedly connected to the outer side of the blocking block 17. The magnetic ring 18 and the rotating plate 8 are fixedly connected. In this step, by setting the blocking block 17 and the magnetic ring 18, after the activated sludge is poured into the inside of the sling-off tank 4, the blocking block 17 is inserted into the opening on the surface of the rotating plate 8 and is attracted to the outer side of the rotating plate 8 by the magnetic ring 18, thereby fixing the blocking block 17 and further sealing the rotating plate 8, thus improving the sealing performance of the device.
[0028] Furthermore, such as Figure 2As shown, a mounting plate 19 is fixedly connected to the outer side of the base 1, and a mounting groove 20 is provided on the surface of the mounting plate 19. By setting the mounting plate 19 and the mounting groove 20, the device can be installed and fixed by screwing screws into the mounting groove 20 and the mounting position before use, which makes the device more stable in position during use and improves the stability of the device.
[0029] Working principle: During use, the hydraulic cylinder 6 drives the cover plate 7 and the rotating plate 8 to move down, so that the cover plate 7 and the rotating plate 8 block and seal the opening of the water-spinning tank 4. The rotating plate 8 drives the locking block 9, the locking plate 10 and the filter screen 11 to move down, so that the filter screen 11 is inserted into the inside of the filter tank 5. The activated sludge is poured into the water-spinning tank 4 through the opening of the rotating plate 8 and rotated. The first motor 3 drives the water-spinning tank 4 and the filter screen 11 to rotate, so that the water contained in the activated sludge is filtered through the filter screen 11 and thrown out into the inside of the drain tank 2. The sewage is discharged through the pipe of the drain tank 2. After filtration is completed, the rotating plate 8 is raised, so that the rotating plate 8 drives the filter screen 11 to rise. By pulling the locking plate 10 and the locking block 9, the filter screen 11 can be easily removed and cleaned.
