Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water treatment, and particularly relates to a sewage treatment and regenerated water production equipment. BACKGROUND

[0002] In the research process of environmental engineering water pollution control, the characteristics of sewage discharge are investigated in the field, and the appropriate sewage treatment mode is selected according to the present 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 smaller than 0.45 microns and are difficult to remove by natural sedimentation. The flocculant can aggregate these fine particles into larger flocs. The flocs formed by flocculation have larger volume and much faster settling velocity than single suspended particles, which can accelerate the settling velocity and improve the treatment efficiency.

[0003] After the flocculant is added to the sewage, the stability of the colloidal particles in the water is changed, and the particles are easy to aggregate. When the colloidal particles move in the water, they will collide with each other. When the particles collide, adsorption occurs between them. The high molecular chains in the flocculant can bridge different particles and make them combine together. Through continuous collision and adsorption, small particles gradually aggregate into larger flocs. The flocs continue to collide and adsorb more particles, gradually growing into larger flocs, until they are large enough to be removed from the water by sedimentation or filtration.

The stirring device includes a rotating shaft, and a plurality of stirring rods are arranged on the rotating shaft. The rotating shaft and the stirring rods are driven to rotate by a motor.

The water vortex can cause part of the flocculants in the water to separate from the water, accelerate 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 opportunity between the flocculants in the water, resulting in low collision rate between the particles in the water, limited effect of flocculating small particles into large flocs, and difficulty in better improving the settling velocity and filtration effect of subsequent sewage treatment.

DETAILED DESCRIPTION

[0033] It should be noted that in the description of the present application, the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0034] The terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first" and "second" can include one or more of the features explicitly or implicitly. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0035] In addition, it should be noted that the connection involved in the present application can be realized by using conventional connection methods, and does not involve any innovation.

[0036] The subject matter involved in the present application is a sewage treatment and reclaimed water production equipment. In the process of environmental engineering water pollution control research, the characteristics of sewage discharge are investigated on site, and the appropriate sewage treatment mode is selected according to the present situation of sewage discharge to improve the sewage treatment rate. When there are a large number of suspended solids and colloidal particles in the sewage, these substances are usually smaller than 0.45 microns, and are difficult to remove by natural sedimentation. The flocculant can aggregate these fine particles into larger flocs, and the flocs formed by flocculation have a larger volume and a much larger settling velocity than single suspended particles, so that the settling velocity can be accelerated and the treatment efficiency can be improved.

[0037] After the flocculant is added into the sewage, the stability of the colloidal particles in the water will be changed, so that the particles are easy to aggregate. When the colloidal particles move in the water, they will collide with each other. When the particles collide, adsorption will occur between them. The high molecular chains in the flocculant can bridge different particles to combine them together. Through continuous collision and adsorption, small particles gradually aggregate into larger flocs. The flocs continue to collide and adsorb more particles, gradually growing into larger flocs, until they are large enough to be removed from the water by sedimentation or filtration.

[0038] 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 produce vortex. The water vortex will cause the colloidal particles in the water to stratify with the water, accelerate the separation of the colloidal particles from the water, and under the action of centrifugal force, most of the flocs and particles move in one direction, reducing the collision opportunity between the colloidal particles in the water, resulting in a low collision rate between the particles in the water, limiting the effect of small particle flocculation into large flocs, and making it difficult to better improve the sedimentation speed and filtration effect of subsequent sewage treatment.

[0039] Based on the above reasons, the present application provides a sewage treatment and regenerated water production equipment to solve the technical problems mentioned above. The following will be combined Figures 1 to 8 with specific embodiments to illustrate the present application in detail.

[0040] Embodiment 1

[0041] The present embodiment provides a sewage treatment and regenerated water production equipment, as shown in Figure 1 , including a cylinder 1, the cylinder 1 is cylindrical and its top is open, the cylinder 1 is used for containing water, further including a ring 2, a rotating mechanism 3, a plurality of turbulence components 4, an elastic net 5, a reciprocating moving component 6.

[0042] The ring 2 is arranged inside the cylinder 1, the shape of the ring 2 matches the shape of the inner wall of the cylinder 1, the ring 2 is a circular ring, and the diameter of the circular ring is slightly smaller than the diameter of the cylinder 1. The output end of the rotating mechanism 3 is connected with the ring 2, and the rotating mechanism 3 is used for driving the ring 2 to rotate. The plurality of turbulence components 4 are arranged on the inner side of the ring 2, and the turbulence component 4 includes a turbulence plate 401 and a connecting piece. The turbulence plate 401 is connected with the ring 2, and the connecting piece is arranged between the turbulence plate 401 and the ring 2, and is used for driving the turbulence plate 401 to rotate through the rotation of the ring 2.

[0043] The elastic net 5 is provided with a circular hole at the center, and the outer ring edges of the elastic net 5 are respectively fixed on the spoiler plates 401 of the plurality of groups of spoiler assemblies 4. The reciprocating moving assembly 6 includes a support column 601 and a sliding ring 602. The support column 601 is coaxially arranged with the cylinder body 1 and is fixed in the cylinder body 1. The sliding ring 602 is threadedly arranged on the support column 601, is connected with the annular part 2 through a connecting piece and rotates with the annular part 2. The outer edge of the sliding ring 602 is connected with the inner edge of the elastic net 5 at the circular hole. After the sliding ring 602 rotates with the annular part 2, the sliding ring 602 moves on the support column 601 along the axial direction of the support column 601, drives 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.

[0044] The water to be treated is discharged into the inside of the cylinder body 1, and a flocculating agent is added in the cylinder body 1. Then, the annular part 2 is driven to rotate by the rotating mechanism. At the same time, the spoiler plates 401 are driven to rotate by the connecting piece, and the rotating directions of the spoiler plates 401 and the annular part 2 are opposite. When the annular part 2 rotates clockwise, the water is driven to rotate forward, and the flocculating agent is preliminarily stirred. The flocculating agent makes the particles in the water gather. At this time, the spoiler plates 401 drive the water to rotate reversely, and the flocculating agent is further stirred. At the same time, the spoiler plates 401 drive the water to rotate reversely, so that the water rotating forward and reversely collides, avoiding the problem that the particles in the water always rotate in one direction and improving the collision opportunity of the particles in the water.

[0045] It should be noted that the single rotation of the spoiler plate 401 is less than one circle, and is reciprocating rotation in the forward and reverse directions. In the description of the embodiment, because the spoiler plate 401 is driven to rotate by the annular part 2, the rotation is described in the form of rotation, and the reciprocating rotation in the forward and reverse directions constitutes a swing motion, that is, the spoiler plate 401 performs a swing motion.

[0046] In addition, the elastic net 5 of the embodiment is a hexagonal structure, and the elastic net 5 is an elastic grid structure which is woven by a wire with elastic properties. Specifically, the wire can be woven by elastic fibers, synthetic rubber and the like. In the embodiment, the elastic net 5 is woven by elastic netting composed of 95% polyester and 5% spandex. The thickness is selectively adapted according to actual needs. When the thickness needs to be adjusted, a multi-layer stacking method is adopted. In addition, it should 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 sliding ring 602 to the spoiler plate 401 is 1.1-1.2:1. This is mainly to consider that the elastic net 5 needs to make room for the movement of the sliding 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 cannot be effectively expanded.

[0047] Preferably, when the plurality of baffles 401 rotate simultaneously towards the center of the barrel 1, the elastic net 5 is collapsed, and when the plurality of baffles 401 rotate simultaneously away from the center of the barrel 1, the elastic net 5 is stretched. Meanwhile, when the elastic net 5 is collapsed, the reciprocating moving assembly 6 drives the elastic net to move upwards or downwards, which can further promote the movement of the particles in different directions.

[0048] Regardless of the annular member 2 or the baffle 401, they drive the water to rotate in a plane. In order to further realize the collision of the water in the vertical direction, the elastic net 5 is arranged to move up and down. The elastic net 5 is connected with the plurality of baffles 401. When the plurality of baffles 401 rotate towards the center of the barrel 1, the elastic net 5 is collapsed. At this time, the reciprocating moving assembly 6 drives the elastic net 5 to move downwards or upwards. When the plurality of baffles 401 rotate away from the center of the barrel 1, the reciprocating moving 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 downwards or upwards, it can drive the particles in the water to move and can push the water to flow. Therefore, the elastic net 5 can drive the particles to move up and down, thereby improving the collision opportunity of the particles in the water.

[0049] In order to fully stretch and collapse the elastic net 5 inside the barrel 1, the baffle 401 is arranged close to the inner wall of the barrel 1. The outermost side of the elastic net 5 is connected with the side of the baffle 401.

[0050] In this embodiment, in order to further improve the collision rate of the particles, the elastic net 5 is provided with at least two groups. The two groups of elastic nets 5 are arranged in an up-down interval. Two slip rings 602 are arranged. The two slip rings 602 are respectively detachably connected with the corresponding elastic nets 5. The sliding directions of the two slip rings 602 are opposite or opposite.

[0051] When the elastic net 5 is collapsed, the holes on the elastic net 5 gradually shrink at this time. The two slip rings 602 move relatively to drive the elastic net 5 to move relatively, so that the particles in the water move relatively.

[0052] When the elastic net 5 is stretched, the holes on the elastic net 5 gradually increase at this time. The two slip rings 602 move oppositely to drive the elastic net 5 to move oppositely. Since the filter holes gradually increase at this time, a part of the smaller particles are missed during the upward movement of the elastic net 5. The larger particles can continue to move upwards with the elastic net 5 to continue to contact and collide with the remaining particles in the water for flocculation.

[0053] The connecting piece comprises a limiting ring 605, a connecting rod 604 and a limiting rod 603, the limiting ring 605 is rotatably sleeved at the top of the supporting column 601, the limiting ring 605 is fixed with one end of the connecting rod 604, the other end of the connecting rod 604 is fixed with the annular piece 2, the bottom of the limiting ring 605 is fixedly connected with the limiting rod 603, a limiting hole is formed in the sliding ring 602, the limiting rod 603 is slidably arranged in the limiting hole, the supporting column 601 is fixedly connected with the cylinder 1, and the two ends of the supporting column 601 are provided with threads in opposite directions, and the two sliding rings 602 are threadedly connected with the two ends of the supporting column 601 respectively.

[0054] In order to realize the movement of the two sliding rings 602 towards or away from each other, the supporting column 601 and the cylinder 1 are fixed, the supporting column 601 is selected as a double-end threaded column, the threads at the two ends are in opposite directions, when the annular piece 2 rotates, the limiting ring 605 is driven to rotate synchronously by the connecting rod 604, the limiting rod 603 is fixedly connected with the limiting ring 605, and the limiting rod 603 rotates with the limiting ring 605, since the limiting rod 603 is slidably arranged in the limiting hole in the sliding ring 602, the limiting rod 603 drives the sliding ring 602 to rotate, since the sliding ring 602 is threadedly connected with the supporting column 601, when the sliding ring 602 rotates, the sliding ring 602 can move up and down.

[0055] Since the elastic net 5 is twisted in the process of being folded or unfolded by the spoiler 401, the holes in the elastic net 5 are compressed, in order to avoid that the holes are moved upwards and drive the particles to move in the opposite direction, thereby reducing the collision rate, the reciprocating moving assembly 6 further comprises a ring-shaped lock catch 606, a groove is formed in the circumferential surface of the sliding ring 602, the lock catch 606 is rotatably arranged in the groove, and the elastic net 5 is fixedly connected with the lock catch 606.

[0056] When the spoiler 401 rotates, the spoiler 401 drives the lock catch 606 to rotate through the elastic net 5, so that the elastic net 5 remains unfolded or folded.

[0057] The use method and working principle of the embodiment are as follows:

[0058] The sewage treatment and regenerated water production equipment provided in the embodiment is used as follows: sewage is first discharged into the cylinder 1 from the top inlet of the cylinder 1, then a flocculating agent is added, the equipment is started, the annular piece 2 is driven to rotate by the rotating mechanism 3, the sewage in the cylinder 1 is rotated and mixed with the flocculating agent, so that the particles in the water begin to gather, at the same time, the spoiler 401 is driven to rotate by the connecting piece, and the rotating direction of the spoiler 401 is opposite to that of the annular piece 2, the water is driven to rotate in the opposite direction by the spoiler 401, so that the water rotating in the positive direction and the water rotating in the opposite direction collide.

[0059] The ring-shaped part 2 rotates while driving the limiting ring 605 to rotate synchronously through the connecting rod 604, the limiting ring 605 drives the sliding ring 602 to rotate through the limiting rod 603, since the sliding ring 602 is threadedly connected with the support column 601, and the threads at the two ends of the support column 601 are opposite in rotation direction, according to the principle of the screw nut, the two sliding rings 602 move relatively or oppositely, the sliding ring 602 drives the elastic net 5 to move, so that the particles in the water collide in the vertical movement to further enhance the flocculation effect.

[0060] The starting time of the device can be selected as 10-40 minutes, and can be actually determined according to the water quality condition of the sewage, the type and amount of the flocculant, the water temperature and other factors. Too short time may lead to incomplete flocculation, and too long time may cause large flocs to be broken, resulting in floating floc on the sewage.

[0061] After the flocculation process is completed, the sewage in the cylinder 1 remains stationary for a period of time, generally 30-60 minutes, and after sedimentation, the water is pumped out from the inside of the cylinder 1, and the bottom of the cylinder 1 is provided with a sewage valve for discharging mud.

[0062] After the water and mud are discharged, the lock catch 606 connected with the elastic net 5 is detached from the sliding ring 602, and the four sides of the elastic net 5 are detached from the plurality of spoiler plates 401, and the elastic net 5 is cleaned and then installed for next use.

When the annular piece 2 rotates, the connecting piece and the spoiler 401 are driven to rotate synchronously. The spoiler 401 rotates with the annular piece 2. When the annular piece 2 rotates, the second gear 404 is driven to move. The second gear 404 is engaged with the inner gear ring 405. Under the action of the inner gear ring 405, the second gear 404 rotates. The rotating direction of the second gear 404 is the same as that of the annular piece 2. The second gear 404 drives the first gear 403 to rotate, so that the first gear 403 rotates in the opposite direction of the annular piece 2.

[0066] In order to facilitate the rotation of the spoiler 401, the rotating shaft 402 is arranged on the side close to the inner wall of the cylinder 1. The rotating shaft 402 is fixedly connected with one side of the spoiler 401. A plurality of through holes are arranged on the spoiler 401.

[0067] The through holes reduce the resistance of water to the spoiler 401.

[0068] In order to fix the elastic net 5, a plurality of spoilers 401 are uniformly arranged along the circumference of the annular piece 2. The elastic net 5 is detachably connected with the side of the spoiler 401 away from the inner wall of the annular piece 2.
