Description

A water treatment device and method based on flocculant and calcium chloride Technical Field

[0001] This invention relates to the field of water treatment, and in particular to a water treatment apparatus and method based on flocculant combined with calcium chloride. Background Technology

[0002] Water treatment refers to the removal of pollutants from water through physical, chemical, and biological methods to bring the water up to specific quality standards to meet the needs of drinking, industrial, or other uses. The water treatment process can be divided into several main steps, including pretreatment, coagulation and flocculation, sedimentation, filtration, disinfection, post-treatment, and sludge treatment, among which flocculation is the most crucial step.

[0003] Currently, the existing flocculation process for water treatment generally involves adding flocculants to the wastewater. However, it is difficult to ensure that the amount of wastewater injected each time is approximately the same. Therefore, it is inconvenient to control the amount of flocculant added each time. Too much or too little will affect the wastewater treatment effect, resulting in poor applicability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a water treatment device and method based on flocculant combined with calcium chloride, overcoming the deficiencies of existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water treatment device based on flocculant combined with calcium chloride, comprising a base plate, on the upper end of which a first treatment tank and a second treatment tank are respectively installed. A water supply pipe is installed at the top of the first treatment tank. A plurality of first springs are evenly and equidistantly connected to the bottom end of the base plate. The upper ends of the plurality of first springs are connected to a movable plate, which matches the first treatment tank. A fixed pipe is connected to one side wall of the first treatment tank. A second spring is connected to the bottom of the fixed pipe. The other end of the second spring is connected to a fixed rod. One end of the fixed rod passes through the opening of the fixed pipe and extends outward and is connected to a baffle. The baffle is slidably connected to the top of the first processing box. A connecting rod is rotatably connected to one side wall of the first processing box. One end of the connecting rod is connected to a stop rod. A stop block is connected to the lower end of the baffle. The stop rod is attached to the stop block. A transmission assembly for driving the connecting rod to rotate is installed inside the first processing box. A reset assembly for resetting the baffle is installed on the moving plate. A water pump is installed on one side wall of the first processing box. A water pump pipe is installed on the side wall of the water pump. The other end of the water pump pipe passes through the side wall of the first processing box and extends inward. A drain pipe is installed at the upper end of the water pump. The other end of the drain pipe passes through the top of the second processing box and extends inward.

[0006] By adopting the above technical solution, during use, sewage is discharged into the first treatment tank through a water supply pipe. As the sewage enters the first treatment tank, the moving plate moves downwards under the force of gravity. This movement compresses the first spring, causing it to deform. The movement of the moving plate, via the transmission assembly, rotates the connecting rod, which in turn rotates the stop rod. When the stop rod disengages from the stop block, the second spring, through the fixed rod, moves the baffle plate, blocking the water supply pipe. At this point, sewage cannot be injected into the first treatment tank. Therefore, the sewage is directed to the first treatment tank... A fixed amount of flocculant is injected into the first treatment tank to treat the wastewater. After the wastewater is treated by the flocculant, the water pump is started, and the treated wastewater is discharged into the second treatment tank through the pumping pipe and the drain pipe. As the wastewater in the first treatment tank is pumped out, the first spring is reset, and the first spring drives the moving plate to move vertically upward. The movement of the moving plate will reset the baffle through the reset component. At this time, wastewater is injected into the first treatment tank again through the water supply pipe. This process is repeated. Through the above structure, a fixed amount of wastewater can be injected into the first treatment tank each time, which makes it convenient to add the corresponding amount of flocculant to the wastewater, thereby improving the wastewater treatment effect.

[0007] As a preferred embodiment of the present invention, the transmission assembly includes a rack fixedly connected to the upper end of the movable plate, and a gear is fixedly sleeved on the wall of the connecting rod, and the gear meshes with the rack.

[0008] By adopting the above technical solution, the movement of the moving plate will drive the rack to move, the movement of the rack will drive the connecting rod to rotate through the gear, and the rotation of the connecting rod will drive the stop rod to rotate, so that the stop rod is moved away from the stop block.

[0009] As a preferred embodiment of the present invention, the reset assembly includes a drive block slidably connected to the top of the first processing box, a drive rod connected to a side wall on one side of the drive block, a storage groove provided on a side wall on one side of the baffle, and the drive rod and the storage groove being positioned correspondingly, a transmission rod hinged to the upper end of the movable plate, and the other end of the transmission rod hinged to the drive block.

[0010] By adopting the above technical solution, the upward movement of the moving plate will apply a force to the driving block through the transmission rod. The driving block will move horizontally due to the force, and the movement of the driving block will drive the driving rod to move. The driving rod will enter the receiving groove in the baffle. When the driving rod continues to move, it will drive the baffle to move and reset the baffle.

[0011] As a preferred embodiment of the present invention, a sliding groove is provided at the top of the first processing box, and a slider is slidably connected in the sliding groove, with one end of the slider connected to the driving block.

[0012] By adopting the above technical solution, the driving block is limited to make it move horizontally.

[0013] As a preferred embodiment of the present invention, a sliding rod is fixedly connected to the inner wall of the chute, the sliding rod passes through the slider, and the slider is slidably connected to the sliding rod.

[0014] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0015] As a preferred embodiment of the present invention, two guide rods are symmetrically connected to the bottom of the first processing box. The guide rods pass through the movable plate, and the movable plate is slidably connected to the two guide rods.

[0016] By adopting the above technical solution, the stability of the moving plate during movement is improved.

[0017] As a preferred embodiment of the present invention, a rotating shaft is rotatably connected to the inner side wall of the second processing box, and a plurality of fan blades are evenly and equidistantly connected to the shaft wall of the rotating shaft, with the drain pipe located directly above the corresponding fan blade.

[0018] By adopting the above technical solution, when the drain pipe discharges sewage into the second treatment tank, calcium chloride is added to the second treatment tank. When the sewage hits the fan blades, the fan blades will rotate through the rotating shaft to stir the sewage, so that the calcium chloride and sewage are fully mixed.

[0019] As a preferred embodiment of the present invention, a filter plate is provided at the bottom of the second processing box, a slag discharge port is provided on one side wall of the second processing box, a first electric push rod is installed on the outer side wall of one side of the second processing box, the piston end of the first electric push rod passes through the side wall of the second processing box and extends inward and is equipped with a pusher plate, the pusher plate is positioned corresponding to the slag discharge port, a second electric push rod is installed at the top of the second processing box, the piston end of the second electric push rod passes through the top of the second processing box and extends downward and is connected to a lifting block, the lifting block is connected to the filter plate by a number of pull ropes.

[0020] By adopting the above technical solution, when calcium chloride purifies wastewater, impurities will be generated and will settle on the filter plate. At this time, the treated wastewater is discharged from the second treatment tank. When it is necessary to clean the impurities on the filter plate, the second electric push rod is activated, which will drive the lifting block to move vertically upward. The movement of the lifting block will drive the filter plate upward through the pull rope. When the filter plate moves to the position of the push plate, the first electric push rod is activated, which will drive the push plate to move. The movement of the push plate will push the impurities on the filter plate and then discharge them through the slag discharge port. The above structure can further treat wastewater and automatically discharge the purified impurities, reducing manual labor and thus improving the applicability of the device.

[0021] A water treatment method based on flocculant combined with calcium chloride, the method employing a water treatment device based on flocculant combined with calcium chloride as described in any one of the above, includes the following steps:

[0022] S1: In use, sewage is discharged into the first treatment tank through the water supply pipe. As the sewage enters the first treatment tank, the moving plate will move downward under the action of gravity. The movement of the moving plate will squeeze the first spring, and the first spring will deform under the action of force. The movement of the moving plate will drive the rack to move. The movement of the rack will drive the connecting rod to rotate through the gear. The rotation of the connecting rod will drive the stop rod to rotate. When the stop rod disengages from the stop block, the second spring will drive the baffle to move through the fixed rod. The baffle will block the water supply pipe. At this time, sewage cannot be injected into the first treatment tank. At this time, a certain amount of flocculant is injected into the first treatment tank to treat the sewage.

[0023] S2: After the wastewater is treated by the flocculant, the water pump is started. The water pump will discharge the treated wastewater into the second treatment tank through the pumping pipe and the drain pipe. As the wastewater in the first treatment tank is pumped out, the first spring will reset. The first spring will drive the moving plate to move vertically upward. The movement of the moving plate will apply a force to the drive block through the transmission rod. The drive block will move horizontally under the force. The movement of the drive block will drive the drive rod to move. The drive rod will enter the receiving groove in the baffle. When the drive rod continues to move, it will drive the baffle to move. The baffle will expose the pipe opening of the water supply pipe. At the same time, the rack and gear will drive the baffle rod to rotate to the position of the stop block to limit the baffle. At this time, wastewater is injected into the first treatment tank through the water supply pipe. This process is repeated. Through the above structure, a certain amount of wastewater can be injected into the first treatment tank each time, which is convenient for adding the corresponding amount of flocculant to the wastewater, thereby improving the wastewater treatment effect.

[0024] S3: When the drain pipe discharges sewage into the second treatment tank, calcium chloride is added to the second treatment tank. When the sewage hits the fan blades, the fan blades will rotate through the rotating shaft to stir the sewage and make the calcium chloride and sewage fully mixed.

[0025] S4: When calcium chloride purifies wastewater, impurities are produced and settle on the filter plate. At this time, the treated wastewater is discharged from the second treatment tank. When it is necessary to clean the impurities on the filter plate, the second electric push rod is activated. The second electric push rod will drive the lifting block to move vertically upward. The movement of the lifting block will drive the filter plate upward through the pull rope. When the filter plate moves to the position of the push plate, the first electric push rod is activated. The movement of the first electric push rod will drive the push plate to move. The movement of the push plate will push the impurities on the filter plate and then discharge them through the slag discharge port. Through the above structure, wastewater can be further treated, and the purified impurities can be automatically discharged, reducing manual labor and thus improving the applicability of the device.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] (1) This invention, through the arrangement of a base plate, a first treatment tank, a water supply pipe, a first spring, a moving plate, a fixed pipe, a second spring, a baffle, a connecting rod, a stop rod, a stop block, a water pump, a pumping pipe, a drain pipe, a rack, a gear, a drive block, a drive rod, and a transmission rod, discharges sewage into the first treatment tank via the water supply pipe. As sewage is injected, the moving plate is subjected to gravity and moves downwards. The movement of the moving plate drives the connecting rod to rotate via the rack and gear. The rotation of the connecting rod drives the stop rod to rotate. When the stop rod disengages from the stop block, the second spring drives the baffle to move via the fixed rod. The baffle then blocks the water supply pipe, preventing sewage from being injected into the first treatment tank. A certain amount of flocculant is then injected into the first treatment tank to treat the sewage. After the sewage is treated by the flocculant, the water pump is started. The treated wastewater is discharged into the second treatment tank through the pumping and draining pipes. As the wastewater in the first treatment tank is drawn out, the first spring drives the moving plate to move vertically upward. The movement of the moving plate drives the drive block to move horizontally through the transmission rod. The movement of the drive block drives the drive rod to move, and the drive rod enters the receiving groove in the baffle. When the drive rod continues to move, it drives the baffle to move, and the baffle exposes the opening of the water supply pipe. At the same time, the rack and pinion drive the stop rod to rotate, so that the stop rod rotates to the stop block position to limit the baffle. At this time, wastewater is injected into the first treatment tank through the water supply pipe. This process is repeated. Through the above structure, a certain amount of wastewater can be injected into the first treatment tank each time, which facilitates the addition of the corresponding amount of flocculant to the wastewater, thereby improving the wastewater treatment effect.

[0028] (2) This invention, through a structure including a second treatment tank, filter plates, a first electric push rod, a pusher plate, a second electric push rod, and a lifting block, allows calcium chloride to be added to the second treatment tank when sewage is discharged into it via a drain pipe. Furthermore, when the sewage impacts the fan blades, the fan blades rotate via a rotating shaft to agitate the sewage, ensuring thorough mixing of the calcium chloride and sewage. After the calcium chloride purifies the sewage, impurities are generated and precipitate on the filter plates. At this point, the treated sewage is discharged from the second treatment tank. When it is necessary to clean the impurities on the filter plates... When the second electric push rod is activated, it drives the lifting block to move vertically upward. The movement of the lifting block, in turn, drives the filter plate upward via the pull rope. When the filter plate moves to the position of the push plate, the first electric push rod is activated. The movement of the first electric push rod drives the push plate to move, which in turn pushes the impurities on the filter plate and discharges them through the slag discharge port. This structure allows for further treatment of wastewater and automatic discharge of purified impurities, reducing manual labor and thus improving the applicability of the device.

The moving plate 6 matches the first treatment box 2. Two guide rods are symmetrically connected to the bottom of the first treatment box 2. The guide rods pass through the moving plate 6 and the moving plate 6 is slidably connected to the two guide rods to improve the stability of the moving plate 6 when it moves.

[0038] Specifically, please refer to Figure 2-4. A fixed tube 7 is connected to one side wall of the first processing box 2. A second spring 8 is connected to the bottom of the inner tube of the fixed tube 7. A fixed rod 28 is connected to the other end of the second spring 8. One end of the fixed rod 28 passes through the opening of the fixed tube 7 and extends outward and is connected to a baffle 9. The baffle 9 is slidably connected to the top of the first processing box 2. A connecting rod 10 is rotatably connected to one side wall of the first processing box 2. A stop rod 11 is connected to one end of the connecting rod 10. A stop block 12 is connected to the lower end of the baffle 9. The stop rod 11 fits against the... On the stop block 12, the first processing box 2 is equipped with a transmission assembly for driving the connecting rod 10 to rotate. The transmission assembly includes a rack 16 fixedly connected to the upper end of the moving plate 6. A gear 17 is fixedly sleeved on the rod wall of the connecting rod 10, and the gear 17 meshes with the rack 16. The movement of the moving plate 6 will drive the rack 16 to move. The movement of the rack 16 will drive the connecting rod 10 to rotate through the gear 17. The rotation of the connecting rod 10 will drive the stop rod 11 to rotate, so that the stop rod 11 is moved away from the stop block 12.

[0039] Specifically, please refer to Figures 2 and 5. A reset assembly for resetting the baffle 9 is installed on the movable plate 6. The reset assembly includes a drive block 18 slidably connected to the top of the first processing box 2. A drive rod 19 is connected to one side wall of the drive block 18. A storage groove is provided on one side wall of the baffle 9, and the drive rod 19 corresponds to the position of the storage groove. A transmission rod 20 is hinged to the upper end of the movable plate 6, and the other end of the transmission rod 20 is hinged to the drive block 18. When the movable plate 6 moves upward, it applies a force to the drive block 18 through the transmission rod 20. The drive block 18, under this force, moves horizontally. The movement of block 18 will drive the drive rod 19 to move, and the drive rod 19 will enter the storage groove in the baffle 9. When the drive rod 19 continues to move, it will drive the baffle 9 to move and reset the baffle 9. The top of the first processing box 2 is provided with a sliding groove, and a slider 21 is slidably connected in the sliding groove. One end of the slider 21 is connected to the drive block 18 to limit the drive block 18 so that the drive block 18 can move in the horizontal direction. A sliding rod 22 is fixedly connected to the inner wall of the sliding groove. The sliding rod 22 passes through the slider 21 and the slider 21 is slidably connected to the sliding rod 22 to prevent the slider 21 from detaching from the sliding groove.

[0040] Specifically, please refer to Figure 2. A water pump 13 is installed on one side wall of the first treatment tank 2, and a water suction pipe 14 is installed on the side wall of the water pump 13. The other end of the water suction pipe 14 passes through the side wall of the first treatment tank 2 and extends inward. A drain pipe 15 is installed on the upper end of the water pump 13, and the other end of the drain pipe 15 passes through the top of the second treatment tank 3 and extends inward. In use, sewage is discharged into the first treatment tank 2 through the water supply pipe 4. As the sewage is injected, the moving plate 6 will be subjected to the force of gravity and move downward. The movement of the moving plate 6 will... When the first spring 5 is squeezed, it deforms under the force. The movement of the moving plate 6 drives the rack 16 to move. The movement of the rack 16 drives the connecting rod 10 to rotate through the gear 17. The rotation of the connecting rod 10 drives the stop rod 11 to rotate. When the stop rod 11 disengages from the stop block 12, the second spring 8 drives the baffle 9 to move through the fixed rod 28. The baffle 9 blocks the water pipe 4. At this time, sewage cannot be injected into the first treatment tank 2. At this time, a certain amount of flocculant is injected into the first treatment tank 2 to treat the sewage.

[0041] After the wastewater is treated by the flocculant, the water pump 13 is started. The water pump 13 discharges the treated wastewater into the second treatment tank 3 through the suction pipe 14 and the drain pipe 15. As the wastewater in the first treatment tank 2 is extracted, the first spring 5 resets, causing the moving plate 6 to move vertically upward. The movement of the moving plate 6 applies a force to the drive block 18 through the transmission rod 20. The drive block 18 moves horizontally due to the force applied, which in turn drives the drive rod 19 to move, causing the drive rod 19 to enter the stop position. When the drive rod 19 continues to move, it will drive the baffle 9 to move, exposing the opening of the water supply pipe 4 in the storage groove inside the plate 9. At the same time, the rack 16 and gear 17 will drive the baffle rod 11 to rotate, so that the baffle rod 11 rotates to the position of the stop block 12 to limit the baffle 9. At this time, sewage is injected into the first treatment tank 2 through the water supply pipe 4. This process is repeated. The above structure can inject a certain amount of sewage into the first treatment tank 2 each time, which makes it convenient to add the corresponding amount of flocculant to the sewage, thereby improving the sewage treatment effect.

[0042] A rotating shaft is rotatably connected to the inner wall of the second treatment tank 3. Several fan blades are evenly and equidistantly connected to the shaft wall, and the drain pipe 15 is located directly above the corresponding fan blades. When the drain pipe 15 discharges sewage into the second treatment tank 3, calcium chloride is added into the second treatment tank 3. When the sewage hits the fan blades, the fan blades will rotate through the rotating shaft to stir the sewage and make the calcium chloride and sewage fully mixed.

[0043] A filter plate 23 is installed at the bottom of the second treatment tank 3. A slag discharge port is opened on one side wall of the second treatment tank 3. A first electric push rod 24 is installed on the outer side wall of one side of the second treatment tank 3. The piston end of the first electric push rod 24 penetrates through the side wall of the second treatment tank 3 and extends inward, and a pusher plate 25 is installed thereon. The pusher plate 25 is positioned corresponding to the slag discharge port. A second electric push rod 26 is installed at the top of the second treatment tank 3. The piston end of the second electric push rod 26 penetrates through the top of the second treatment tank 3 and extends downward, and is connected to a lifting block 27. The lifting block 27 is connected to the filter plate 23 by several pull ropes. When calcium chloride purifies the wastewater, impurities will be generated, and these impurities will settle on the filter plate 23. At this time, the treated wastewater is discharged from the first electric push rod 24. The wastewater is discharged into the secondary treatment tank 3. When it is necessary to clean the impurities on the filter plate 23, the second electric push rod 26 is activated. The second electric push rod 26 will drive the lifting block 27 to move vertically upward. The movement of the lifting block 27 will drive the filter plate 23 to move upward through the pull rope. When the filter plate 23 moves to the position of the pusher plate 25, the first electric push rod 24 is activated. The movement of the first electric push rod 24 will drive the pusher plate 25 to move. The movement of the pusher plate 25 will push the impurities on the filter plate 23 and discharge them through the slag discharge port. The above structure can further treat the wastewater and automatically discharge the purified impurities, reducing manual labor and thus improving the applicability of the device.

[0044] Working principle: During use, sewage is discharged into the first treatment tank 2 through the water supply pipe 4. As the sewage enters the first treatment tank 2, the moving plate 6 moves downward under the force of gravity. The movement of the moving plate 6 compresses the first spring 5, causing the first spring 5 to deform. The movement of the moving plate 6 drives the rack 16 to move, which in turn drives the connecting rod 10 to rotate through the gear 17. The rotation of the connecting rod 10 drives the stop rod 11 to rotate. When the stop rod 11 disengages from the stop block 12, the second spring 8 drives the baffle 9 to move through the fixed rod 28. The baffle 9 blocks the water supply pipe 4, preventing sewage from entering the first treatment tank 2. At this time, a certain amount of flocculant is injected into the first treatment tank 2 to treat the sewage.

[0045] After the wastewater is treated by the flocculant, the water pump 13 is started. The water pump 13 will discharge the treated wastewater into the second treatment tank 3 through the water pumping pipe 14 and the drain pipe 15. As the wastewater in the first treatment tank 2 is extracted, the first spring 5 will reset. The first spring 5 will drive the moving plate 6 to move vertically upward. The movement of the moving plate 6 will apply a force to the drive block 18 through the transmission rod 20. The drive block 18 will move horizontally under the force. The movement of the drive block 18 will drive the drive rod 19 to move. The drive rod 19 will enter the receiving groove in the baffle 9. When the drive rod 19 continues to move, it will drive the baffle 9 to move. The baffle 9 will expose the opening of the water supply pipe 4. At the same time, the rack 16 and the gear 17 will also drive the baffle rod 11 to rotate, so that the baffle rod 11 rotates to the position of the stop block 12 to limit the baffle 9. At this time, wastewater is injected into the first treatment tank 2 through the water supply pipe 4. This process is repeated.

[0046] When the drain pipe 15 discharges sewage into the second treatment tank 3, calcium chloride is added to the second treatment tank 3. When the sewage hits the fan blades, the fan blades will rotate via the rotating shaft to stir the sewage, so that the calcium chloride and sewage are fully mixed. After the calcium chloride purifies the sewage, impurities will be produced, and the impurities will settle on the filter plate 23. At this time, the treated sewage is discharged from the second treatment tank 3. When it is necessary to clean the impurities on the filter plate 23, the second electric push rod 26 is activated. The second electric push rod 26 will drive the lifting block 27 to move vertically upward. The movement of the lifting block 27 will drive the filter plate 23 to move upward through the pull rope. When the filter plate 23 moves to the position of the push plate 25, the first electric push rod 24 is activated. The movement of the first electric push rod 24 will drive the push plate 25 to move. The movement of the push plate 25 will push the impurities on the filter plate 23, and then discharge the impurities through the slag discharge port.

3. A water treatment method based on flocculant combined with calcium chloride as described in claim 1 or 2, characterized in that, Includes the following steps: S1: In use, sewage is discharged into the first treatment tank (2) through the water pipe (4). The sewage will enter the first treatment tank (2). As the sewage is injected, the moving plate (6) will be subjected to gravity and move downward. The movement of the moving plate (6) will squeeze the first spring (5). The first spring (5) will deform under the force. The movement of the moving plate (6) will drive the rack (16) to move. The movement of the rack (16) will drive the connecting rod (10) to rotate through the gear (17). The rotation of the connecting rod (10) will drive the stop rod (11) to rotate. When the stop rod (11) moves from the stop... When the block (12) is detached, the second spring (8) will drive the baffle (9) to move through the fixed rod (28), and the baffle (9) will block the water pipe (4). At this time, the sewage cannot be injected into the first treatment tank (2). At this time, a certain amount of flocculant is injected into the first treatment tank (2) to treat the sewage; S2: After the sewage is treated by the flocculant, the water pump (13) is started. The water pump (13) will discharge the treated sewage into the second treatment tank (3) through the water pump pipe (14) and the drain pipe (15). As the sewage in the first treatment tank (2) is extracted, the first spring (5) will reset. Spring (5) will drive the moving plate (6) to move vertically upward. The movement of the moving plate (6) will exert a force on the driving block (18) through the transmission rod (20). The driving block (18) will move horizontally under the force. The movement of the driving block (18) will drive the driving rod (19) to move. The driving rod (19) will enter the receiving groove in the baffle (9). When the driving rod (19) continues to move, it will drive the baffle (9) to move. The baffle (9) will expose the opening of the water pipe (4). At the same time, the rack (16) and gear (17) will also drive the baffle (11) to rotate. Rotate the baffle (11) to the position of the baffle (12) to limit the baffle (9). At this time, sewage is injected into the first treatment tank (2) through the water supply pipe 4. Repeat this process. Through the above structure, a certain amount of sewage can be injected into the first treatment tank (2) each time, which makes it convenient to add the corresponding amount of flocculant to the sewage, thereby improving the sewage treatment effect. S3: When the drain pipe (15) discharges sewage into the second treatment tank (3), calcium chloride is added into the second treatment tank (3). When the sewage hits the fan blade, the fan blade will rotate through the rotating shaft to stir the sewage and make the calcium chloride and sewage fully mixed.S4: When calcium chloride purifies wastewater, impurities are generated and settle on the filter plate (23). At this time, the treated wastewater is discharged from the second treatment tank (3). When it is necessary to clean the impurities on the filter plate (23), the second electric push rod (26) is activated. The second electric push rod (26) will drive the lifting block (27) to move vertically upward. The movement of the lifting block (27) will drive the filter plate (23) upward through the pull rope. When the filter plate (23) moves to the position of the push plate (25), the first electric push rod (24) is activated. The movement of the first electric push rod (24) will drive the push plate (25) to move. The movement of the push plate (25) will push the impurities on the filter plate (23) and discharge them through the slag discharge port. Through the above structure, wastewater can be further treated, and the purified impurities can be automatically discharged, reducing manual labor and thus improving the applicability of the device.
