Description

Technical Field

[0001] The invention belongs to the technical field of sewage purification equipment, in particular to a sewage purification device and a method thereof. Background Art

[0002] After the sludge is dehydrated, the separated sewage needs to be purified. The sewage is first subjected to chemical flocculation and sedimentation to remove some colloids and suspended matter, and then flows into the sedimentation tank for deep mud and water separation. Then it is filtered, and fine impurities are intercepted by multi-layer filter screens. Finally, it enters the disinfection stage, and ultraviolet rays or disinfectants are used to kill bacteria, thereby completing the purification and making the sewage meet the discharge standards or reuse. The coordinated operation of each step can effectively remove suspended matter, organic matter, pathogens and impurities in the sewage after sludge dehydration, so that the treated sewage meets the discharge standards or can be reused, reducing pollution to the environment and waste of water resources.

[0003] The existing technology has the following problems: first, the impurity particles in the sewage are of different sizes. Larger impurities are directly filtered together with the sewage, which will reduce the service life of the filter and increase the risk of filter clogging. Moreover, the larger impurities still need to be separated again after being separated from the sewage for subsequent unified treatment and recycling.

[0004] Secondly, the sewage relies on gravity to pass through the holes of the filter, and the filter rotates to separate the sewage and impurities into layers, so as to separate the impurities and sewage. However, the sewage forms a stable rotating state on the filter due to centrifugal force. All of the above make the efficiency of sewage passing through the filter limited. Therefore, the present invention provides a sewage purification treatment device and method. Summary of the invention

[0014] A sewage purification method, applied to a sewage purification device, comprises the following steps:

[0015] S1: First, the motor drives the power shaft and the upper cylinder to rotate. At the same time, the sewage and its accompanying impurities are crushed by a pair of crushing rings and enter the inner cylinder. The sewage is filtered through multiple layers of filters. At the same time, the sewage and impurities are separated by centrifugal force. The impurities are separated and collected by the receiving ring, and the sewage is collected and discharged;

[0016] S2: Then, the lifting cone ring is driven up and down by the power shaft. When the lifting cone ring moves down to one vertical end of the Y cylinder, it squeezes the air below it, so that the efficiency of sewage passing through the filter holes is increased. At the same time, the valve on the water inlet pipe is closed, so that the impurities and sewage in the crushing tooth ring are sucked, avoiding the accumulation of impurities inside the crushing tooth ring;

[0017] S3: Finally, the filter is driven to rotate by the power shaft while driving the roller to rotate. Because the second bevel gear and the bevel gear ring are meshed, the anti-blocking column on the roller is continuously inserted into the filter holes to avoid clogging of the filter holes. At the same time, the bottom of the filter is backwashed regularly through the flushing box to avoid clogging of the filter.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The sewage purification treatment device and method described in the present invention, through the sewage from the water inlet pipe into a pair of crushing gears, the sewage quickly passes through the crushing gears and enters the filter through the lifting ring cone, and the impurities attached thereto are crushed by the pair of crushing gears rotating in the opposite direction. The pre-crushing of impurities can prevent large particles from clogging the filter, optimize the flow of liquid in the filter, and is conducive to the separation and recovery of impurities, improve the subsequent treatment effect, and can extend the service life of the filter, reduce the wear of the filter, and reduce the risk of failure.

[0020] 2. The sewage purification treatment device and method described in the present invention drives the lifting cone ring to rise and fall by a power shaft. When the lifting cone ring rises, the sewage passes through the lifting cone ring and falls onto the filter. Since the upper opening of the Y-tube is relatively large, it will not affect the filtration efficiency of the sewage entering the filter. When the lifting cone ring descends to the vertical opening end of the Y-tube, the air at its bottom is compressed, thereby increasing the efficiency of the sewage passing through the filter. At this time, the impurities in the crushing tooth ring are sucked and quickly pass through and fall onto the lifting cone ring and the filter, and are finally collected, thereby avoiding the accumulation of fine impurities in the crushing tooth ring.

[0021] 3. The sewage purification treatment device and method described in the present invention drives the filter screen to vibrate by squeezing the arc block through the fixed rod, so as to prevent the sewage on the filter screen from entering the filter screen holes downward due to the centrifugal force and reducing the efficiency. The vibration of the filter screen can destroy the stable rotation state of the sewage on the filter disk formed by the centrifugal force, so that the relative positions between the sewage molecules and the impurity particles are constantly changing. During the vibration process, the sewage is more likely to find the holes on the filter disk and pass through. From the energy point of view, the vibration provides additional kinetic energy for the sewage, helping the sewage to overcome resistance such as centrifugal force and surface tension, thereby speeding up the speed of passing through the filter disk.

[0022] 4. The sewage purification treatment device and method described in the present invention drives the rotating shaft to perform circular motion with the power shaft as the axis through the power shaft. At the same time, because the second bevel gear and the bevel gear ring are engaged, the roller drives the anti-blocking column to rotate. At the same time, the anti-blocking column continuously enters the filter holes to clear the blockages in the filter holes and avoid blockage of the filter holes.

[0023] 5. The sewage purification treatment device and method described in the present invention, by closing the valve on the water inlet pipe, sewage no longer enters the cylinder body, thereby avoiding air circulation above the lifting cone ring. When the lifting cone ring slides at one vertical end of the Y cylinder, the air pressure above it is squeezed. The air pressure is transmitted through the air pipe and the bifurcated pipe, and pushes the sliding plate to move horizontally, so that the sliding plate squeezes the water on one side of it. The water flow is sprayed out through the flushing groove in the flushing box to backwash the holes below the filter screen to avoid clogging of the filter screen holes, or the sliding plate is reset to the side away from the cylinder body.

[0024] 6. The sewage purification treatment device and method described in the present invention, by arranging a knife bar on the through groove, can make the middle cylinder rotate and drive the knife bar to rotate accordingly, cutting impurities inside the water flow and creating a segmentation effect on larger particle impurities.

[0025] 7. The sewage purification treatment device and method described in the present invention adopts a graded hole design to set larger holes near the edge area because the centrifugal force on the liquid here is larger and a larger channel is needed to allow the liquid to pass quickly; smaller holes are set near the center area, and at the same time, the hole edges are designed to be funnel-shaped to make it easier for the liquid to be sucked into the holes.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figures 1 to 10As shown, a sewage purification treatment device and method according to an embodiment of the present invention comprises a cylinder 1; an outer cylinder is arranged inside the cylinder 1, and the outer cylinder is composed of an upper cylinder 111, a middle cylinder 112 and a lower cylinder 113 in sequence; the top of the cylinder 1 is rotatably connected to the upper cylinder 111 through a first circular groove, the upper cylinder 111 and the middle cylinder 112 are fixedly connected, the middle cylinder 112 and the lower cylinder 113 are rotatably connected, a power shaft 12 is rotatably connected inside the upper cylinder 111, and the lower cylinder 113 is fixedly connected to the inner wall of the cylinder 1; the inner cylinder is fixedly connected to the top of the inner wall of the lower cylinder 113, and the inner cylinder is connected to the inner wall of the cylinder 1 through a sealing ring 131 , the Y-tube 132 and the funnel tube 133 are fixedly connected in sequence, and the tip of the funnel tube 133 is set downward, the sealing ring 131 is fixedly connected to the top of the lower tube 113, and a group of receiving rings 134 are fixedly connected to the outer circular wall of the funnel tube 133 through a group of ring grooves 3, and a group of receiving rings 134 are provided with a filter groove 135 at the lower end; a group of lifting rings 14 are provided on the power shaft 12, and a group of lifting rings 14 are fixedly connected to a filter screen 15, and a group of fixing rods 16 are provided on the funnel tube 133, and a group of arc blocks 161 are fixedly connected to the outer circular wall of the bottom end of the filter screen 15, and the arc blocks 161 and The positions of the fixing rods 16 correspond to each other; a pair of crushing tooth rings 17 are fixedly connected to the inner ring wall of the middle cylinder 112 and the power shaft 12, and the positions of the pair of crushing tooth rings 17 correspond to each other; a group of fixing blocks 18 are fixedly connected to the bottom of the sealing ring 131, and the side walls of the fixing blocks 18 are fixedly connected to the inner wall of the Y cylinder 132, and a lifting cone ring 19 is slidably connected between a group of the fixing blocks 18, and the power shaft 12 is threadedly connected to the lifting cone ring 19 through a thread groove; a power piece is provided on the top of the cylinder 1, and the power shaft 12 and the outer cylinder are driven by the power piece; a sewage inlet and outlet piece and an impurity discharge piece are provided inside the cylinder 1; During operation, the power shaft 12, the upper cylinder 111, and the middle cylinder 112 are driven by the power member to rotate in the opposite direction at the same time, and the sewage enters the pair of crushing tooth rings 17 from the water inlet pipe 2. The sewage quickly passes through the crushing tooth rings 17 and enters the filter screen 15 through the lifting ring 14 cone. The impurities attached thereto are crushed by the pair of crushing tooth rings 17 rotating in the opposite direction. The pre-crushing of impurities can prevent large particles from clogging the filter screen 15, optimize the flow of liquid in the filter screen 15, and is conducive to the separation and recovery of impurities, improve the subsequent treatment effect, and can extend the service life of the filter screen 15, reduce the wear of the filter screen 15, and reduce the risk of failure;The lifting cone ring 19 is driven to rise and fall by the power shaft 12. When the lifting cone ring 19 rises, the sewage passes through the lifting cone ring 19 and falls onto the filter screen 15. Since the upper end opening of the Y cylinder 132 is relatively large, it does not affect the filtering efficiency of the sewage entering the filter screen 15. When the lifting cone ring 19 descends to the vertical opening end of the Y cylinder 132, the air at its bottom is compressed, so that the passing efficiency of the sewage through the filter screen 15 is increased. At this time, the impurities in the crushing tooth ring 17 are sucked and quickly fall onto the lifting cone ring 19 and the filter screen 15, and are finally collected, thereby avoiding the accumulation of fine impurities in the crushing tooth ring 17. At the same time, the filter screen 15 During rotation, the fixed rod 16 squeezes the arc block 161 to drive the filter 15 and the lifting ring 14 to vibrate, preventing the sewage on the filter 15 from entering the holes of the filter 15 due to centrifugal force, which reduces the efficiency. The vibration of the filter 15 can destroy the stable rotation state of the sewage on the filter disc due to the centrifugal force, so that the relative positions between the sewage molecules and the impurity particles are constantly changing. During the vibration process, the sewage is more likely to find the holes on the filter disc and pass through. From the energy point of view, the vibration provides additional kinetic energy for the sewage, helping the sewage to overcome resistance such as centrifugal force and surface tension, thereby accelerating the speed of passing through the filter disc. ;

The sewage is finally collected through the outlet pipe 25. When the filter screen 15 rotates to provide centrifugal force, the sewage and impurities are separated due to the different densities of the impurities and sewage. The impurities are collected out of the cylinder body 1 through the receiving ring 134. The opening depth and diameter of the filter screen 15 are set differently, so that the angular velocity of the sewage on the filter screen 15 is different. Because the centrifugal force is also different, the filter screen 15 is set layer by layer, and the diameter of its holes decreases as the diameter of the filter screen 15 decreases. The sewage on the upper filter screen 15 is subjected to a greater centrifugal force and larger impurities are filtered. Similarly, the sewage on the lower filter screen 15 is subjected to a smaller centrifugal force and smaller impurities are filtered.

[0051] The diameter of the holes on a group of the filter screens 15 gradually increases from the center to the edge, and the cross-section of the holes at the edge of the filter screen 15 is funnel-shaped, and the tip of the funnel is set downward; a pair of the crushing tooth rings 17 are each provided with a pair of inclined surfaces 8 on the top, and the pair of inclined surfaces 8 are set opposite to each other; a pair of the crushing tooth rings 17 are each provided with a group of water troughs 81 on the top; when working, a graded hole design is adopted, and larger holes are set near the edge area, because the centrifugal force on the liquid here is greater, and a larger channel is required for the liquid to pass quickly; smaller holes are set near the center area, and at the same time, the hole edges are designed to be funnel-shaped to make it easier for the liquid to be sucked into the holes.

[0052] A sewage purification method, applied to a sewage purification device, comprises the following steps:

[0053] S1: First, the motor 7 drives the power shaft 12 and the upper cylinder 111 to rotate, and the sewage and its accompanying impurities are crushed by a pair of crushing gear rings 17 and enter the inner cylinder. The sewage is filtered by the multi-layer filter 15, and the sewage and impurities are separated by centrifugal force. The impurities are separated and collected by the receiving ring 134, and the sewage is collected and discharged;

[0054] S2: Then, the lifting cone ring 19 is driven to rise and fall by the power shaft 12. When the lifting cone ring 19 moves down to one vertical end of the Y cylinder 132, the air below it is squeezed, so that the efficiency of sewage passing through the holes of the filter screen 15 is increased, and at the same time, the valve on the water inlet pipe 2 is closed, so that the impurities and sewage in the crushing tooth ring 17 are sucked, thereby preventing the accumulation of impurities inside the crushing tooth ring 17;

[0055] S3: Finally, the filter screen 15 is driven to rotate by the power shaft 12 while driving the roller 41 to rotate. Because the second bevel gear 43 and the bevel gear ring 44 are meshed, the anti-blocking column 42 on the roller 41 is continuously inserted into the holes of the filter screen 15 to prevent the holes of the filter screen 15 from being blocked. At the same time, the bottom of the filter screen 15 is backwashed regularly through the flushing box 53 to prevent the filter screen 15 from being blocked.

[0056] Working principle: The power shaft 12 and the upper cylinder 111 and the middle cylinder 112 are driven by the power parts to rotate in opposite directions at the same time, and the sewage enters the pair of crushing tooth rings 17 from the water inlet pipe 2. The sewage quickly passes through the crushing tooth rings 17 and enters the filter screen 15 through the lifting ring 14 cone. The impurities attached thereto are crushed by the pair of crushing tooth rings 17 rotating in opposite directions. The pre-crushing of impurities can prevent large particles from clogging the filter screen 15, optimize the flow of liquid in the filter screen 15, and is conducive to the separation and recovery of impurities, improve the subsequent treatment effect, and prolong the service life of the filter screen 15, reduce the wear of the filter screen 15, and reduce the risk of failure; the lifting cone ring 19 is driven to rise and fall by the power shaft 12. When the lifting cone ring 19 rises, the sewage passes through the lifting cone ring 19 and falls to the filter On the filter 15, since the upper end opening of the Y cylinder 132 is relatively large, it does not affect the filtering efficiency of the sewage entering the filter 15. When the lifting cone ring 19 descends to the vertical opening end of the Y cylinder 132, the air at its bottom is compressed, so that the passing efficiency of the sewage through the filter 15 is increased, and at this time, the impurities in the crushing tooth ring 17 are sucked and quickly fall onto the lifting cone ring 19 and the filter 15, and are finally collected, thereby avoiding the accumulation of fine impurities in the crushing tooth ring 17. At the same time, when the filter 15 rotates, the fixed rod 16 squeezes the arc block 161 to drive the filter 15 and the lifting ring 14 to vibrate, thereby avoiding the sewage on the filter 15 from entering the filter 15 holes downward due to centrifugal force. The efficiency is reduced, and the vibration of the filter 15 can destroy the sewage on the filter plate due to centrifugal force. The stable rotating state formed causes the relative positions between sewage molecules and impurity particles to change continuously. During the vibration process, sewage can more easily find the holes on the filter disc and pass through. From an energy perspective, vibration provides additional kinetic energy for sewage, helping sewage to overcome resistances such as centrifugal force and surface tension, thereby accelerating the speed of passing through the filter disc. Through the establishment of the through groove 21, sewage passes through the water inlet pipe 2 and enters the upper cylinder 111 through the through groove 21, and then enters the Y cylinder 132 and the filter screen 15 in turn to complete the filtration. The sewage is finally collected through the outlet pipe 25. When the filter screen 15 rotates to provide centrifugal force, the impurities and sewage are separated into layers due to their different densities, and the impurities are collected out of the cylinder 1 through the receiving ring 134. The filter screen 15 has different opening depths and diameters, so that the angular velocity of the sewage on the filter screen 15 is different. Because the centrifugal force is also different, the filter screen 15 is set up layer by layer, and the diameter of the hole decreases as the diameter of the filter screen 15 decreases. The sewage on the upper filter screen 15 is subjected to a greater centrifugal force and filters larger impurities. Similarly, the sewage on the lower filter screen 15 is subjected to a smaller centrifugal force and filters smaller impurities. The ring groove 3 and the vertically arranged limit groove 31 are combined to enable the lifting ring 14 to have the conditions for up and down vibration, destroying the stable rotation state of the sewage on the filter disc due to the centrifugal force, so that the sewage can enter the holes of the filter screen 15 more efficiently, and the impurities pass through the filter groove 135 on the receiving ring 134 and enter between the outer collecting ring 33 and the inner collecting ring 34.Finally, it is discharged from the cylinder 1 through the outlet pipe 24 to complete the collection for subsequent treatment. The power shaft 12 drives the rotating shaft 4 to perform a circular motion with the power shaft 12 as the axis. At the same time, because the second bevel gear 43 and the bevel gear ring 44 are meshed, the roller 41 drives the anti-blocking column 42 to rotate. At the same time, the anti-blocking column 42 continuously enters the holes of the filter screen 15 to dredge the blockages in the holes of the filter screen 15 to avoid blockage of the holes of the filter screen 15. By closing the valve on the water inlet pipe 2, the sewage no longer enters the cylinder 1, and the air circulation above the lifting cone ring 19 is avoided. When the lifting cone ring 19 slides vertically at one end of the Y cylinder 132, the air pressure above it is squeezed. The air pressure is transmitted through the air pipe 52 and the bifurcated pipe 56, and the sliding plate 51 is pushed to move horizontally, so that the sliding plate 51 squeezes the water on one side thereof, and the water flow is sprayed out through the flushing groove in the flushing box 53 to press the filter screen 15 below. The holes on the sides are backwashed to avoid clogging of the holes of the filter screen 15, or the sliding plate 51 is reset to the side away from the cylinder 1. By setting a knife strip 6 on the through groove 21, the middle cylinder 112 can be rotated to drive the knife strip 6 to rotate accordingly, cutting the impurities inside the water flow, and causing a segmentation effect on larger particle impurities. The motor 7 drives the first bevel gear 71 on its output end to rotate, thereby driving a pair of bevel gears to rotate in opposite directions, and at the same time drives the outer cylinder and the power shaft 12 to rotate in opposite directions, so as to complete the effect of crushing impurities through a pair of crushing tooth blocks. A graded hole design is adopted, and larger holes are set near the edge area, because the centrifugal force on the liquid here is larger, and a larger channel is required for the liquid to pass quickly; smaller holes are set near the center area, and at the same time, the hole edge is designed to be funnel-shaped, so that the liquid is more easily sucked into the hole. ,
