Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment, and particularly relates to a sewage treatment and reclaimed water production device. Background Art

[0002] During the field research on the characteristics of sewage discharge in the process of environmental engineering water pollution control research, a suitable sewage treatment mode is selected according to local conditions based on the current situation of sewage discharge to improve the sewage treatment rate. Sewage usually contains a large amount of suspended solids and colloidal particles, which are usually less than 0.45 microns and are difficult to remove by natural sedimentation. Flocculants can aggregate these fine particles into larger flocs. The flocs formed by flocculation have a larger volume, and the sedimentation speed is much greater than that of a single suspended particle. In this way, the sedimentation speed can be accelerated and the treatment efficiency can be improved.

[0003] After the flocculant is added to the sewage, it will change the stability of the colloidal particles in the water, making these particles easy to aggregate. When the destabilized colloidal particles move in the water, they will collide with each other. When the particles collide, adsorption will occur between them. The polymer chains in the flocculant can bridge different particles and bind them together. Through continuous collision and adsorption, small particles gradually aggregate into larger flocs, and the flocs continue to adsorb more particles through collision and gradually grow into larger flocs until they are large enough to be removed from the water by sedimentation or filtration.

[0004] In the prior art, a stirring device is usually arranged in the flocculation tank. The stirring device includes a rotating shaft, and several stirring rods are arranged on the rotating shaft. The rotating shaft and the stirring rods are driven to rotate by a motor. The existing stirring device is easy to drive the water to generate vortices. The water vortices will cause some flocs in the water to be stratified from the water, accelerating the separation of the flocs from the water. And under the action of centrifugal force, most of the flocs and particles move in one direction, reducing the collision chance between the flocculent particles in the water, resulting in a low collision rate between the particles in the water, making the effect of aggregating small particles into large flocs limited, and it is difficult to better improve the sedimentation speed and filtration effect of subsequent sewage treatment. Summary of the Invention

[0005] In view of this, the present invention provides a sewage treatment and reclaimed water production device, which can improve the collision rate between the particles in the water to better improve the sedimentation speed and filtration effect of subsequent sewage treatment.

The flow disturbing component includes a flow disturbing plate and a connecting member. The flow disturbing plate is rotatably connected to the annular member. The connecting member is arranged between the flow disturbing plate and the annular member and is used to drive the flow disturbing plate to rotate through the rotation of the annular member; An elastic net is provided with a circular hole at the center, and the outer ring edges are respectively fixed on the flow disturbing plates of multiple groups of flow disturbing components; A reciprocating movement component includes: a support column, which is arranged coaxially with the cylinder body and fixed inside the cylinder body; a slip ring, which is threadedly arranged on the support column, is connected to the annular member through a connecting member and rotates with the annular member. The outer edge of the slip ring is connected to the inner edge of the elastic net at the circular hole. After the slip ring rotates with the annular member, it moves along the axis of the support column on the support column, driving the inner edge of the elastic net at the circular hole to move.

[0007] Preferably, when multiple flow disturbing plates rotate towards the center of the cylinder body simultaneously, the elastic net contracts; when multiple flow disturbing plates rotate in a direction away from the center of the cylinder body simultaneously, the elastic net expands. At the same time, when the elastic net contracts, the elastic net is driven to move up or down through the reciprocating movement component.

Two slip rings are provided, and the two slip rings are detachably connected to the corresponding elastic nets respectively, and the sliding directions of the two slip rings are opposite or relative.

[0009] Preferably, the reciprocating movement component further includes an annular lock. A groove is formed on the circumferential surface of the slip ring, and the lock is rotatably arranged in the groove, and the elastic net is fixedly connected to the lock.

[0010] Preferably, annular support plates are fixedly connected to both the top and bottom of the annular member. Rotating shafts are fixedly connected to both the upper and lower ends of the flow disturbing plate, and the rotating shafts are rotatably connected to the support plates. The output end of the connecting member is connected to the rotating shaft to drive the rotating shaft to rotate so as to realize the rotation of the flow disturbing plate.

[0011] Preferably, the rotating shaft is arranged on one side close to the inner wall of the cylinder body, and a plurality of through holes are formed on the flow disturbing plate.

[0012] Preferably, multiple flow disturbing plates are evenly arranged along the circumferential direction of the annular member, and the elastic net is detachably connected to the side of the flow disturbing plate away from the inner wall of the annular member.

The convex platform is slidably arranged inside the guide rail. A plurality of balls are rotatably embedded in the inner bottom of the guide rail, and the balls support the convex platform.

[0015] Compared with the prior art, the beneficial effects of a sewage treatment and reclaimed water production device provided by the present invention are as follows: By arranging a ring-shaped member inside the cylinder body and arranging multiple groups of flow disturbing components inside the ring-shaped member, the flow disturbing components include flow disturbing plates. The ring-shaped member is driven to rotate by a rotating mechanism. While the ring-shaped member rotates, the flow disturbing plates are driven to rotate through a connecting member. When the flow disturbing plates rotate, the particles in the water are driven to move. At the same time, an elastic net is arranged in the cylinder body. When multiple flow disturbing plates rotate towards the center of the cylinder body at the same time, the elastic net contracts. When multiple flow disturbing plates rotate in a direction away from the center of the cylinder body at the same time, the elastic net expands. At the same time, when the elastic net contracts, the elastic net is driven to move up or down by a reciprocating motion component, which can further promote the particles to move in different directions, improve the collision rate between the particles, and promote the flocculation of small particles into large flocs, so as to better improve the sedimentation speed and filtration efficiency of subsequent sewage treatment.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0027] In addition, it should be noted that the connections involved in the present invention can be achieved by using conventional connection methods and do not involve any innovation.

[0028] The subject matter of the present invention relates to a sewage treatment and reclaimed water production device. During the research process of environmental engineering water pollution control, the characteristics of sewage discharge are investigated on-site, and a suitable sewage treatment mode is selected according to local conditions based on the current situation of sewage discharge to improve the sewage treatment rate. When the sewage contains a large amount of suspended solids and colloidal particles, these substances are usually less than 0.45 microns and are difficult to remove by natural sedimentation. Flocculants can aggregate these fine particles into larger flocs. The flocs formed by flocculation have a larger volume and a sedimentation rate much greater than that of a single suspended particle, which can accelerate the sedimentation rate and improve the treatment efficiency.

[0029] After the flocculant is added to the sewage, it will change the stability of the colloidal particles in the water, making these particles easy to aggregate. When the destabilized colloidal particles move in the water, they will collide with each other. When the particles collide, adsorption will occur between them. The polymer chains in the flocculant can bridge different particles and bind them together. Through continuous collisions and adsorption, small particles gradually aggregate into larger flocs. The flocs continue to adsorb more particles through collisions and gradually grow into larger flocs until they are large enough to be removed from the water by sedimentation or filtration.

[0030] In the prior art, a stirring device is usually arranged in the flocculation tank. The existing stirring device is easy to drive the water to generate vortices. The water vortices will cause some flocculants in the water to be stratified from the water, accelerating the separation of the flocculants from the water. And under the action of centrifugal force, most of the flocs and particles move in one direction, reducing the collision opportunities between the flocculant particles in the water, resulting in a low collision rate between the particles in the water, making the effect of flocculating small particles into large flocs limited, and it is difficult to better improve the sedimentation speed and filtration effect of subsequent sewage treatment.

[0031] For the above reasons, the present invention provides a sewage treatment and reclaimed water production device to facilitate solving the above-mentioned technical problems. The following will be combined with Figures 1 to 8 , and the present invention will be described in detail.

[0032] Embodiment 1 This embodiment provides a sewage treatment and reclaimed water production device, as Figure 1 shown, including a cylinder body 1. The cylinder body 1 is cylindrical and its top is open. The cylinder body 1 is used for holding water, and further includes an annular member 2, a rotating mechanism 3, multiple groups of flow disturbing components 4, an elastic net 5, and a reciprocating moving component 6.

[0033] Among them, the annular member 2 is arranged inside the cylinder body 1. The shape of the annular member 2 matches the inner wall shape of the cylinder body 1. The annular member 2 is a ring, and the diameter of the ring is slightly smaller than the diameter of the cylinder body 1. The output end of the rotating mechanism 3 is connected to the annular member 2, and the rotating mechanism 3 is used to drive the annular member 2 to rotate. Multiple groups of flow disturbing components 4 are arranged inside the annular member 2. The flow disturbing component 4 includes a flow disturbing plate 401 and a connecting member. The flow disturbing plate 401 is rotatably connected to the annular member 2, and the connecting member is arranged between the flow disturbing plate 401 and the annular member 2 for driving the flow disturbing plate 401 to rotate through the rotation of the annular member 2.

[0034] A circular hole is arranged at the center of the elastic net 5, and the outer ring edges of the elastic net 5 are respectively fixed on the spoiler plates 401 of the plurality of spoiler assemblies 4. The reciprocating assembly 6 comprises a support column 601 and a slip ring 602, wherein the support column 601 is coaxially arranged with the cylinder 1 and fixed in the cylinder 1, the slip ring 602 is threadedly arranged on the support column 601, connected with the annular member 2 through a connecting member and rotates with the annular member 2, the outer edge of the slip ring 602 is connected with the inner edge of the elastic net 5 at the circular hole, and the slip ring 602 moves on the support column 601 along the axial direction of the support column 601 after rotating with the annular member 2, driving the inner edge of the elastic net 5 at the circular hole to move, and the elastic net 5 can drive the particles in the water to move when moving.

[0035] The water to be treated is discharged into the cylinder 1, and flocculants are added into the cylinder 1. Then, the annular member 2 is driven to rotate by the rotating mechanism. While the annular member 2 rotates, the spoiler 401 is driven to rotate by the connecting member, and the rotation direction of the spoiler 401 is opposite to that of the annular member 2. When the annular member 2 rotates clockwise, the water is driven to rotate in the forward direction, and the flocculant is initially stirred. The flocculant causes the particles in the water to aggregate. At this time, the spoiler 401 drives the water to rotate in the reverse direction, and further stirs the flocculant. At the same time, the spoiler 401 drives the water to rotate in the reverse direction, causing the forward and reverse rotating water to collide, thereby avoiding the problem that the particles in the water rotate in one direction all the time and increasing the collision chance of the particles in the water.

[0036] It should be noted that a single rotation of the spoiler 401 is less than one circle, and is a reciprocating rotation in the forward and reverse directions. When describing this embodiment, because the spoiler 401 is driven to rotate by the ring member 2, it is described in the scheme in a rotating manner, and its reciprocating rotation in the forward and reverse directions constitutes a swinging motion, that is, the spoiler 401 is performing a swinging motion.

[0037] In addition, the elastic net 5 of this embodiment is a hexagonal structure, and the elastic net 5 is an elastic grid structure, which is woven with elastic threads, and can be specifically woven with threads made of elastic fibers, synthetic rubber, and the like. This embodiment uses 95% polyester and 5% spandex to form an elastic mesh yarn woven with elastic threads. The specific thickness is selectively adapted according to actual needs, and when the thickness needs to be adjusted, it is achieved by multi-layer superposition. It should also be noted that the ratio of the radius of the circumscribed circle of the elastic net 5 to the shortest straight-line distance from the slip ring 602 to the spoiler 401 is 1.1-1.2:1, which is mainly due to the fact that the elastic net 5 needs to make room for the movement of the slip ring 602. However, the size of the elastic net 5 should not be too large. If the size of the elastic net 5 is too large, the elastic net 5 will not be able to be folded well, especially the elastic net 5 cannot be effectively unfolded.

[0038] Preferably, when multiple spoilers 401 rotate toward the center of the cylinder 1 at the same time, the elastic net 5 is retracted, and when multiple spoilers 5 rotate away from the center of the cylinder 1 at the same time, the elastic net 5 is expanded. At the same time, when the elastic net 5 is retracted, the reciprocating motion component 6 drives the elastic net to move upward or downward, which can further promote the movement of particles in different directions.

[0039] Whether it is the annular member 2 or the spoiler 401, both drive the water to rotate in a plane, and in order to further realize the vertical collision of water, an elastic net 5 is provided, the elastic net 5 moves up and down, and the elastic net 5 is connected to a plurality of spoilers 401. When the spoilers 401 all rotate toward the center of the cylinder 1, the elastic net 5 can be folded, and the reciprocating assembly 6 drives the elastic net 5 to move downward or upward. When the spoilers 401 all rotate in the direction away from the center of the cylinder 1, the reciprocating assembly 6 drives the elastic net 5 to reset. Since the mesh structure of the elastic net 5 has a filtering effect, when the elastic net 5 moves downward or upward, it can drive the particles in the water to move and promote the water flow. Therefore, the elastic net 5 can drive the particles to move up and down, thereby increasing the collision chance of the particles in the water.

[0040] In order to fully expand and collapse the elastic net 5 inside the cylinder 1 , the spoiler 401 is arranged on a side close to the inner wall of the cylinder 1 , and the outermost edge of the elastic net 5 is connected to the side edge of the spoiler 401 .

[0041] In this embodiment, in order to further improve the collision rate of particles, at least two groups of elastic nets 5 are provided, and the two groups of elastic nets 5 are arranged at intervals up and down. Two slip rings 602 are provided, and the two slip rings 602 are detachably connected to the corresponding elastic nets 5 respectively, and the sliding directions of the two slip rings 602 are relative or opposite.

[0042] When the elastic net 5 is folded, the holes on the elastic net 5 gradually shrink, and the two sliding rings 602 move relative to each other, driving the elastic net 5 to move relative to each other, thereby causing the particles in the water to move relative to each other.

[0043] When the elastic net 5 is stretched, the holes on the elastic net 5 gradually increase, and the two sliding rings 602 move in opposite directions, driving the elastic net 5 to move in opposite directions. Since the filter holes gradually increase at this time, smaller particles are partially missed during the upward movement of the elastic net 5, and larger particles can continue to move upward with the elastic net 5 to continue to contact and collide with the remaining particles in the water to be flocculated.

[0044] Among them, the connecting part includes a limit ring 605, a connecting rod 604, and a limit rod 603. The limit ring 605 is rotatably sleeved on the top of the support column 601, the limit ring 605 is fixed to one end of the connecting rod 604, and the other end of the connecting rod 604 is fixed to the ring member 2. The bottom of the limit ring 605 is fixedly connected to the limit rod 603, and a limit hole is provided on the slip ring 602. The limit rod 603 is slidably inserted into the limit hole. The support column 601 is fixedly connected to the cylinder 1, and threads with opposite rotation directions are arranged at both ends of the support column 601. The two slip rings 602 are respectively threadedly connected to the two ends of the support column 601.

[0045] In order to realize the two slip rings 602 to move toward or against each other, the support column 601 and the cylinder 1 are fixed, and the support column 601 selects a double-headed threaded column, and the threads at both ends are in opposite directions. When the annular member 2 rotates, the limit ring 605 is driven to rotate synchronously through the connecting rod 604. The limit rod 603 is fixedly connected to the limit ring 605, and the limit rod 603 rotates with the limit ring 605. Since the limit rod 603 slides through the limit hole on the slip ring 602, the limit rod 603 drives the slip ring 602 to rotate. Since the slip ring 602 and the support column 601 are threadedly connected, the slip ring 602 can move up and down when it rotates.

[0046] As the spoiler 401 rotates and drives the elastic net 5 to close or expand, the elastic net 5 will be twisted, and the twisting compresses the holes on the elastic net 5. In order to avoid the particles moving in the opposite direction to reduce the collision rate during the upward movement of the holes, the reciprocating moving component 6 also includes an annular lock 606. A groove is provided on the circumference of the slip ring 602. The lock 606 is rotatably set in the groove, and the elastic net 5 is fixedly connected to the lock 606.

[0047] When the spoiler 401 rotates, the spoiler 401 drives the lock 606 to rotate through the elastic net 5, so that the elastic net 5 keeps being expanded or retracted in the positive direction.

[0048] The usage and working principle of this embodiment: The sewage treatment reclaimed water production equipment provided in this embodiment, when in use, first discharges the sewage into the interior of the cylinder 1 from the top inlet of the cylinder 1, then adds flocculant, starts the equipment, and drives the annular member 2 to rotate through the rotating mechanism 3. The sewage rotates in the cylinder 1 and mixes with the flocculant so that the particles in the water begin to gather. At the same time, the spoiler 401 is driven to rotate through the connecting member, and the rotation direction of the spoiler 401 is opposite to that of the annular member 2. The spoiler 401 drives the water to rotate in the opposite direction so that the forward and reverse rotating water collides.

[0049] While the annular member 2 rotates, it drives the limit ring 605 to rotate synchronously through the connecting rod 604. The limit ring 605 drives the slip ring 602 to rotate through the limit rod 603. Since the slip ring 602 is threadedly connected to the support column 601 and the thread directions at both ends of the support column 601 are opposite, according to the principle of the screw nut, the two slip rings 602 move relatively or in the opposite direction. The slip ring 602 drives the elastic net 5 to move, causing the particles in the water to collide during the vertical movement, further enhancing the flocculation effect.

[0050] The start-up time of the equipment can be selected from 10 minutes to 40 minutes, and it can be actually determined according to factors such as the water quality of the sewage, the type and dosage of the flocculant, and the water temperature. Too short a time may result in incomplete flocculation, and too long a time may cause large flocs to be broken up, resulting in floating flocs above the sewage.

[0051] After the flocculation process is completed, the sewage inside the cylinder 1 is kept static for a period of time, usually 30 minutes to 60 minutes. After precipitation, water is pumped out from the inside of the cylinder 1 through a water pump. A sewage discharge valve is provided at the bottom of the cylinder 1, and sludge is discharged through the sewage discharge valve.

[0052] After draining and discharging sludge, the buckle 606 connected to the elastic net 5 is removed from the slip ring 602, and the four sides of the elastic net 5 are removed from the multiple spoiler plates 401. After cleaning the elastic net 5, it is reinstalled and prepared for the next use.

[0053] Embodiment 2 On the basis of Embodiment 1, in order to make the rotation direction of the spoiler plate 401 opposite to that of the annular member 2 to improve the particle collision rate, this embodiment further includes two annular support plates 7. The two support plates 7 are fixedly connected to the top and bottom of the annular member 2 respectively. The connecting member includes a rotating shaft 402, a first gear 403, a second gear 404, and an internal gear ring 405. The internal gear ring 405 is fixedly connected to the top of the cylinder 1. The rotating shaft 402 is fixedly connected to the spoiler plate 401. Both ends of the rotating shaft 402 are rotatably connected to the two support plates 7. The first gear 403 is sleeved and fixed on the upper end of the rotating shaft 402. The second gear 404 is rotatably arranged on the support plate 7. The second gear 404 meshes with the first gear 403, and the second gear 404 meshes with the internal gear ring 405.

[0054] Two support plates 7 are provided to facilitate the relative fixation of the connecting member and the spoiler 401 to the annular member 2. When the annular member 2 rotates, it drives the connecting member and the spoiler 401 to rotate synchronously. The spoiler 401 revolves with the annular member 2. When the annular member 2 rotates, it drives the second gear 404 to move. The second gear 404 meshes with the internal gear ring 405. Under the action of the internal gear ring 405, the second gear 404 rotates, and the rotation direction of the second gear 404 is the same as that of the annular member 2. The second gear 404 drives the first gear 403 to rotate, so that the first gear 403 rotates in the opposite direction to the annular member 2.

[0055] To facilitate driving the spoiler 401 to rotate, the rotating shaft 402 is arranged on one side close to the inner wall of the cylinder body 1. The rotating shaft 402 is fixedly connected to one side of the spoiler 401. A plurality of through holes are provided on the spoiler 401.

[0056] The function of the through holes is to reduce the resistance of water to the spoiler 401.

[0057] To fix the elastic net 5, a plurality of spoilers 401 are evenly arranged along the circumferential direction of the annular member 2. The elastic net 5 is detachably connected to the side of the spoiler 401 away from the inner wall of the annular member 2.

[0058] The number of spoilers 401 is set to at least three to ensure the full unfolding and fixation of the elastic net 5. To further increase the coverage area of the elastic net 5, the number of elastic nets 5 is set to six in this embodiment.

[0059] Usage method and working principle of this embodiment When the equipment provided in this embodiment is in use, when the annular member 2 rotates, the rotating shaft 402 and the second gear 404 fixedly connected to the annular member 2 revolve accordingly. The second gear 404 meshes with the internal gear ring 405, and the internal gear ring 405 is fixedly connected to the cylinder body 1. Therefore, the second gear 404 can rotate while revolving, and the rotation direction is the same as that of the annular member 2. The second gear 404 drives the first gear 403 to rotate. When the annular member 2 rotates clockwise, the first gear 403 rotates clockwise. When the annular member 2 rotates counterclockwise, the first gear 403 rotates counterclockwise. The first gear 403 can drive the rotating shaft 402 and the spoiler 401 to rotate. The rotation of the spoiler 401 drives the water and particles to rotate in the opposite direction to the annular member 2, improving the collision rate of the particles in the water.

[0060] Embodiment 3 Based on the above embodiments, in order to realize the rotation of the annular member 2, a specific embodiment of the rotating mechanism 3 is provided. Specifically, the rotating mechanism 3 includes a motor 301, an external gear ring 303, and a third gear 302. The third gear 302 is rotatably arranged outside the cylinder body 1. The external gear ring 303 is fixedly connected to the top of the annular member 2. The external gear ring 303 meshes with the third gear 302. The motor 301 is arranged outside the cylinder body 1. The axle of the third gear 302 is connected to the output shaft of the motor 301.

[0061] Among them, the motor 301 can be a stepper motor. The motor 301 is connected to a motor controller and can drive the third gear 302 to rotate forward and backward. During the forward rotation of the third gear 302, the spoiler 401 rotates from one side close to the inner wall of the cylinder body 1 to the opposite side close to the inner wall of the cylinder body 1. During the reverse rotation of the third gear 302, the spoiler 401 rotates in the reverse direction. And so on in a cycle.

[0062] In order to prevent the resistance of the water pressure to the annular member 2 from being too large and causing the annular member 2 to be unable to rotate, an annular guide rail 8 is provided at the bottom of the cylinder body 1. A boss 10 is connected to the bottom of the annular member 2. The boss 10 is slidably arranged inside the guide rail 8. A number of balls 9 are rotatably embedded in the inner bottom of the guide rail 8. The balls 9 support the boss 10.

[0063] A gasket is provided between the guide rail 8 and the boss 10 to prevent impurities in the sewage from entering the guide rail 8 and affecting the operation of the equipment.

[0064] The usage method and working principle of this embodiment For the sewage treatment and reclaimed water production equipment provided in this embodiment, when in use, start the motor 301, and control the forward and reverse rotations of the motor 301 through the motor controller. When the motor 301 rotates forward, it drives the third gear 302 to rotate. The third gear 302 drives the annular member 2 to rotate forward through the external gear ring 303 meshing with it. When the spoiler 401 rotates from one side close to the inner wall of the cylinder body 1 to the opposite side close to the inner wall of the cylinder body 1, the motor controller controls the motor 301 to rotate in the reverse direction, driving the annular member 2 to rotate in the reverse direction. During this process, the spoiler 401 returns, completing one cycle. In this way, the cycle continuously drives the particles in the water to move, increasing the collision rate of the particles in the water. After continuous collision and adsorption, the small particles are coagulated and then precipitated and separated, improving the speed and effect of sedimentation and filtration.

[0065] The above-disclosed are only the preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto.
