A flocculation device for water treatment

Abstract

This invention discloses a flocculation device for water treatment, comprising a swing flocculation component, a push-pull component, and auxiliary components. The swing flocculation component includes a flocculation reaction cylinder, which is a double-kidney-shaped cylindrical structure with one independent chamber on each side. The two independent chambers are connected above each other by a connecting channel, the interior of which is embedded a first filter screen. The forward and reverse rotation of the flocculation reaction cylinder causes wastewater to flow between the two sides, preventing flocculant from settling or adhering to the walls, and naturally separating the flocculated sediment into two parts, improving solid-liquid separation efficiency. A push-pull plate moving along its axis within the independent chamber accelerates flocculant mixing and prevents floc fragmentation, while also cleaning the first filter screen, ensuring efficient wastewater transfer. By changing the properties of the push-pull plate, the effect of forcibly discharging the flocculated sediment is achieved, resulting in higher working efficiency.

Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically to a flocculation device for water treatment. Background Technology

[0002] Water treatment methods include physical treatment and chemical treatment. Flocculation treatment is often set at the beginning of water treatment to remove small particulate solid impurities in the water. Specifically, solid impurity flocculation refers to the process of agglomerating and enlarging suspended particles in water or liquid to form flocs, thereby accelerating particle sedimentation and facilitating solid-liquid separation. Flocculation is usually achieved by adding appropriate flocculants, which adsorb particles and "bridge" between them, thus promoting aggregation.

[0003] In order to improve the mixing efficiency between flocculant and wastewater and shorten the floc formation time, some existing flocculation equipment incorporates agitator devices. However, when the agitator is working, on the one hand, the vortex formed by its stable operation causes the flocculant to be "thrown" to the edge, resulting in a "wall-adhering" phenomenon. At the same time, the flocculant that settles to the bottom lacks the upward momentum, thus reducing the mixing efficiency between flocculant and wastewater. On the other hand, the rotating agitator also increases the probability of flocs being broken up, thereby affecting the stable formation and maintenance of flocs and hindering the efficient flocculation reaction. Summary of the Invention

[0004] The present invention provides a flocculation device for water treatment to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flocculation device for water treatment includes a swing flocculation component, a push-pull component, and an auxiliary component. The swing flocculation component includes a flocculation reaction cylinder, which is a double-kidney-shaped cylindrical structure with an independent chamber on each side. The two independent chambers are connected above each other by a connecting channel. A first filter screen is embedded inside the connecting channel. By driving the flocculation reaction cylinder to rotate in both directions, the sewage flows between the two independent chambers, preventing the flocculant from settling to the bottom or sticking to the wall under the centrifugal effect of the stirring paddle, thus improving the mixing effect between the flocculant and the sewage. At the same time, it naturally divides the flocculated sediment into two parts. When the sewage completely flows into one independent chamber, the flocculated sediment trapped on the other side by the first filter screen will be discharged more easily, improving the efficiency of solid-liquid separation.

[0007] The swing flocculation assembly also includes toothed rings installed on both sides of the outside of the flocculation reaction cylinder. Supporting gears are meshed on both sides of the bottom of the toothed rings. Supporting legs are connected to the sides of the supporting gears through their central shafts. A first motor is connected to the central shaft of one of the supporting gears.

[0008] One end of the flocculation reaction cylinder is equipped with an end cap, and the other end of the flocculation reaction cylinder is equipped with single-chamber sealing caps on both sides. Hydraulic cylinders are connected to the upper and lower parts of the single-chamber sealing caps, and the cylinder bodies of the hydraulic cylinders are respectively installed on the upper and lower parts of the flocculation reaction cylinder.

[0009] The top two sides of the flocculation reaction cylinder are respectively equipped with feeding pipes that communicate with each independent chamber, and the bottom two sides of the flocculation reaction cylinder are respectively equipped with water inlet and outlet pipes that communicate with each independent chamber.

[0010] The push-pull assembly includes push-pull plates disposed in two independent chambers and adapted to the shape of their inner walls. The upper and lower sides of the push-pull plates are provided with through holes. By moving the push-pull plates back and forth in the independent chambers along their axial direction, the sewage can undergo reverse recombination and diffusion through the through holes, which can accelerate the mixing of flocculant and sewage, while avoiding the flocculants from being broken when the stirring paddle rotates, thus ensuring the flocculation reaction efficiency.

[0011] The push-pull assembly also includes screws located at the centers of two independent chambers. One end of each screw protrudes from one end of an independent chamber and is rotatably connected to the center of both sides of the end cap. A second motor is connected to one end of each screw, and a bracket is rotatably connected to the other end of each screw. The outer end of the bracket is installed on the inner wall of the other end of the independent chamber. A threaded sleeve is installed at the center of each push-pull plate, and the center of each threaded sleeve is threadedly connected to the outside of the screw.

[0012] The auxiliary component includes multiple outer rings that are threaded into the through holes. Each outer ring has a second filter screen in its inner ring. The auxiliary component also includes tenons located above and below one side of the outer ring. The tenons are symmetrical about the center of the outer ring. One end of each tenon is semi-open and the other end is fully open. The auxiliary component also includes multiple turntables that correspond to the positions of the outer rings and are rotatably connected to the inside of the end cap. Each turntable has a U-shaped tenon that mates with the tenon. The rotation shafts of the turntables pass through the end cap and are connected to a third motor.

[0013] When the U-shaped tenon is fitted into the mortise, the rotating turntable allows the outer ring to be screwed in or out of the through hole. The use of the push-pull plate is changed by whether the outer ring is screwed into the through hole to set the second filter screen. When yes, the push-pull plate moves to one end of the independent chamber. After the second filter screen is set inside the through hole, the sewage in the independent chamber on that side is transferred to the other independent chamber. The push-pull plate moves to the other end. At this time, through the squeezing of the push-pull plate and the filtration of the second filter screen, the flocculated sediment after solid-liquid separation is concentrated at the single-chamber sealing cover. Opening the single-chamber sealing cover on that side can achieve the effect of forcibly discharging the flocculated sediment.

[0014] As a preferred embodiment of the present invention, the upper middle part of the end cap is provided with a window communicating with the communicating cavity, and a filter screen sealing cover for sealing the first filter screen is installed inside the window.

[0015] As a preferred embodiment of the present invention, the bottom ports of the inlet and outlet water pipes are both connected to a three-way valve. One side of the three-way valve is used to connect to a sewage supply pipe, and the other side of the three-way valve is used to connect to a pipe for collecting flocculation reaction clarified water.

[0016] As a preferred embodiment of the present invention, the swaying flocculation assembly further includes a base serving as a support leg, with the bottom of the support leg respectively mounted on the top of the base.

[0017] As a preferred embodiment of the present invention, the housing of the first motor is mounted on the side of the support leg.

[0018] In a preferred embodiment of the present invention, the housing of the second motor is mounted on both sides of the center of the end cover.

[0019] As a preferred embodiment of the present invention, the push-pull assembly further includes slide bars respectively installed on the upper and lower inner walls of the two independent chambers, and the slide bars are respectively matched with the edges of the push-pull plate.

[0020] As a preferred embodiment of the present invention, when the U-shaped tenon is made of a magnetic material, the outer ring shall be made of a metal material that can be magnetically attracted.

[0021] As a preferred embodiment of the present invention, the housing of the third motor is installed at the four outer corners of the end cover.

[0022] This invention drives the flocculation reaction cylinder to rotate in both directions, causing wastewater to flow between two independent chambers. This prevents the flocculant from settling to the bottom or sticking to the walls under the centrifugal effect of the stirring paddle, thus improving the mixing effect between the flocculant and the wastewater. At the same time, it naturally separates the flocculated sediment into two parts. When the wastewater completely flows into one independent chamber, the flocculated sediment trapped on the other side by the first filter screen will be discharged more easily, improving the efficiency of solid-liquid separation.

[0023] This invention utilizes a push-pull plate that matches the shape of the inner wall of an independent chamber, which moves back and forth along its axis within the chamber. This allows wastewater to undergo reverse recombination and diffusion through through-holes, accelerating the mixing of flocculant and wastewater. Simultaneously, it prevents the agitator from breaking up the flocs during rotation, ensuring efficient flocculation. Furthermore, it can scrape off flocculent deposits adhering to the surface of the first filter screen, preventing clogging and ensuring efficient wastewater transfer. The reciprocating transfer of wastewater also provides a backwashing effect on the first filter screen, further preventing clogging.

[0024] This invention alters the function of the push-pull plate by installing a second filter screen inside the through-hole. After the second filter screen is installed inside the through-hole, the wastewater in the independent chamber on one side is transferred to the independent chamber on the other side, and the push-pull plate moves to the other end. At this time, through the squeezing of the push-pull plate and the filtration of the second filter screen, the flocculated sediment after solid-liquid separation is concentrated at the single-chamber sealing cover. Opening the single-chamber sealing cover on that side achieves the effect of forcibly discharging the flocculated sediment, resulting in lower water content and higher working efficiency.

[0025] This invention uses multiple devices placed side by side and fixed in place, with toothed rings meshing between adjacent devices. Depending on the specific implementation, one or more power sources can be selectively used to drive the flocculation reaction cylinder to rotate in both directions, thereby saving on equipment investment.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0039] like Figure 1 As shown, this embodiment of the invention provides a flocculation device for water treatment, including a swing flocculation component 1, a push-pull component 2, and an auxiliary component 3, wherein, reference... Figure 2-4 The oscillating flocculation component 1 includes a flocculation reaction cylinder 101, which is a double-kidney-shaped cylindrical structure with an independent chamber on each side. The two independent chambers are connected above each other by a connecting channel. A first filter screen 102 is embedded inside the connecting channel. By driving the flocculation reaction cylinder 101 to rotate in both directions, the sewage is transferred and flows between the two independent chambers, preventing the flocculant from settling to the bottom or sticking to the wall under the centrifugal effect of the stirring paddle, thus improving the mixing effect between the flocculant and the sewage. At the same time, it naturally divides the flocculated sediment into two parts. When the sewage completely flows into one independent chamber, the flocculated sediment trapped on the other side by the first filter screen 102 will be more easily discharged, improving the efficiency of solid-liquid separation.

[0040] In this embodiment, reference continues. Figure 2-3The oscillating flocculation assembly 1 also includes toothed rings 107 installed on both sides of the outside of the flocculation reaction cylinder 101. Supporting gears 108 are meshed on both sides of the bottom of the toothed rings 107. Supporting legs 109 are connected to the sides of the supporting gears 108 through their central shafts. The central shaft of one of the supporting gears 108 is connected to a first motor 110. The housing of the first motor 110 is installed on the side of the supporting leg 109. The first motor 110 drives the supporting gear 108 to rotate, and under the support of the other supporting gears 108, the flocculation reaction cylinder 101 can perform stable forward and reverse rotation with the help of the toothed rings 107.

[0041] In this embodiment, refer again Figure 2-3 One end of the flocculation reaction cylinder 101 is equipped with an end cap 103, and the other end of the flocculation reaction cylinder 101 is provided with single-chamber sealing caps 105 on both sides. Hydraulic cylinders 106 are connected to the upper and lower parts of the single-chamber sealing caps 105. The cylinder bodies of the hydraulic cylinders 106 are respectively installed on the upper and lower parts of the flocculation reaction cylinder 101. The single-chamber sealing caps 105 can be opened freely and selectively through the hydraulic cylinders 106, so as to better match the discharge of flocculated sediment.

[0042] In this embodiment, refer again Figure 1-2 The top two sides of the flocculation reaction cylinder 101 are respectively equipped with feeding pipes 112 that communicate with each independent chamber. The feeding pipes 112 are used to feed flocculants and other agents. The bottom two sides of the flocculation reaction cylinder 101 are respectively equipped with inlet and outlet water pipes 113 that communicate with each independent chamber. The bottom ports of the inlet and outlet water pipes 113 are connected to three-way valves 114. One side of the three-way valve 114 is used to connect to the sewage supply pipe, and the other side of the three-way valve 114 is used to connect to the pipe for collecting the clarified water from the flocculation reaction.

[0043] In this embodiment, reference Figure 5-6 The push-pull assembly 2 includes push-pull plates 204 disposed in two independent chambers and adapted to the shape of their inner walls. The upper and lower sides of the push-pull plates 204 are provided with through holes 206. By moving the push-pull plates 204 back and forth in the independent chambers along their axial direction, the sewage can undergo reverse recombination and diffusion through the through holes 206, which can accelerate the mixing of flocculant and sewage, while avoiding the flocs from being broken when the stirring paddle rotates, thus ensuring the flocculation reaction efficiency.

[0044] In this embodiment, reference continues. Figure 5-6The push-pull assembly 2 also includes screws 201 disposed at the centers of two independent chambers. One end of each screw 201 extends from one end of an independent chamber and is rotatably connected to the center sides of the end cover 103. A second motor 203 is connected to one end of each screw 201, and the housing of the second motor 203 is correspondingly installed on the center sides of the end cover 103. A bracket 202 is rotatably connected to the other end of each screw 201, and the outer end of the bracket 202 is correspondingly installed on the inner wall of the other end of the independent chamber. Threaded sleeves 205 are installed at the center of each push-pull plate 204, and the center of each threaded sleeve 205 corresponds to a threaded connection. Outside the screw 201, the second motor 203 drives the screw 201 to rotate. With the support 202 stabilizing it, the push-pull plate 204 can reciprocate along the axis of the independent chamber with the help of the threaded sleeve 205. The moving push-pull plate 204 can mix sewage and flocculant on the one hand, and scrape off the flocculent deposits attached to the surface of the first filter screen 102 on the other hand, so as to avoid the first filter screen 102 from clogging and ensure the efficiency of sewage transfer. The reciprocating transfer of sewage can also backwash the first filter screen 102, further preventing clogging.

[0045] In this embodiment, reference Figure 7 The auxiliary component 3 includes multiple outer rings 301 that are threadedly connected to the inside of the through hole 206, and each outer ring 301 has a second filter screen 302 in its inner ring.

[0046] In this embodiment, reference continues. Figure 8-10 The auxiliary component 3 also includes tenons 306 located above and below one side of the outer ring 301. The tenons 306 are symmetrical about the center of the outer ring 301. One end of the tenon 306 is semi-open and the other end is fully open. The auxiliary component 3 also includes multiple turntables 303 corresponding to the position of the outer ring 301 and rotatably connected to the inside of the end cover 103. The upper and lower sides of the inner side of the turntable 303 are equipped with U-shaped tenons 304 that correspond to the tenons 306. The rotation shafts of the turntables 303 pass through the end cover 103 and are all connected to a third motor 305.

[0047] When the U-shaped tenon 304 is fitted into the mortise 306, the outer ring 301 can be screwed into or out of the through hole 206 by rotating the turntable 303.

[0048] In this embodiment, the housing of the third motor 305 is installed at the four outer corners of the end cover 103. When the second filter screen 302 needs to be removed, the push-pull plate 204 is first moved to one end of the independent chamber until the U-shaped tenon 304 enters the interior of the tenon 306 from the fully open end of the tenon 306. Then, the third motor 305 drives the turntable 303 to rotate, causing the U-shaped tenon 304 to shift to the semi-open end of the tenon 306. Then, the turntable 303 continues to rotate in the same direction, and the push-pull plate 204 slowly moves away, so that the outer ring 301 rotates out from the interior of the through hole 206. At this time, the push-pull plate 204 can only be used to mix sewage and flocculant, and to scrape off the surface of the first filter screen 102. Conversely, when the second filter screen 302 is set inside the through hole 206, the push-pull plate 204 will also be used for forced solid-liquid separation.

[0049] The above-mentioned method changes the usage of the push-pull plate 204 by whether or not the outer ring 301 is screwed into the through hole 206 to set the second filter screen 302. When the second filter screen 302 is set inside the through hole 206, the sewage in the independent chamber on that side is transferred to the independent chamber on the other side, and the push-pull plate 204 moves to the other end. At this time, through the squeezing of the push-pull plate 204 and the filtration of the second filter screen 302, the flocculated sediment after solid-liquid separation is concentrated at the single chamber sealing cover 105. Opening the single chamber sealing cover 105 on that side can achieve the effect of forcibly discharging the flocculated sediment, resulting in lower water content and higher working efficiency.

[0050] In this embodiment, the end cap 103 has a window communicating with the communicating cavity at its upper center. A filter screen sealing cover 104, used to seal the first filter screen 102, is installed inside the window. By removing the filter screen sealing cover 104, the first filter screen 102 can be replaced and maintained through the window. The swinging flocculation assembly 1 also includes a base 111 for supporting the support legs 109, with the bottoms of the support legs 109 respectively mounted on the top of the base 111. In this embodiment, referring again... Figure 4 and Figure 6 The push-pull assembly 2 also includes slide bars 207 installed on the upper and lower inner walls of the two independent chambers respectively. The slide bars 207 are respectively matched with the edges of the push-pull plate 204 to stabilize the state of the push-pull plate 204 during movement. Example 2

[0051] The difference between this embodiment and Embodiment 1 lies in the material used for the U-shaped tenon 304. In this embodiment, when the U-shaped tenon 304 is made of a magnetic material, the outer ring 301 is made of a metal material that can be magnetically attracted. In specific implementation, when the second filter screen 302 needs to be removed, the U-shaped tenon 304 is inserted into the interior of the mortise 306 from the fully open end of the mortise 306. Then, the turntable 303 is rotated, causing the U-shaped tenon 304 to shift to the semi-open end of the mortise 306. Then, the turntable 303 is continuously rotated in the same direction, causing the outer ring 301 to spin out from the interior of the through hole 206. At this time, when the push-pull plate 204 moves away, due to the magnetic attraction between the U-shaped tenon 304 and the outer ring 301, the outer ring 301, together with the second filter screen 302, will be more stably picked up by the U-shaped tenon 304, ensuring that the outer ring 301 will not be impacted when the sewage flows violently. Furthermore, it also ensures the stability of the outer ring 301 when it is reset later. Example 3

[0052] like Figure 11 As shown, in order to improve the ease of use and applicability of this equipment, this embodiment provides a modular approach to using this equipment, namely, a technical solution for combining multiple pieces of this equipment. In a specific implementation, multiple pieces of equipment are placed side by side and fixed, and the toothed rings 107 between adjacent pieces of equipment are meshed and connected. At this time, depending on the specific implementation, one or more first motors 110 can be selectively used to drive the flocculation reaction cylinder 101 to rotate forward and backward, thereby saving equipment investment.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
