Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for mouthwash production. Background Technology

[0002] Mouthwash production generates a large amount of high-concentration organic wastewater. This type of wastewater typically contains surfactants, alcohol, flavorings, pigments, sweeteners, and some bactericidal components. It is characterized by high COD (chemical oxygen demand) concentration, strong foaming properties, and large fluctuations in water quality. If discharged directly without effective treatment, it will cause serious pollution to the receiving water environment.

[0003] Currently, coagulants and wastewater are mixed using mechanical or hydraulic stirring. The stirring paddles are usually fixed, resulting in a relatively uniform flow pattern during mixing. This can easily lead to short-circuiting or dead zones, causing insufficient mixing of the coagulant and wastewater and affecting the destabilization of colloids. Flocculants are often added at fixed points or through simple pipeline mixing, resulting in poor uniformity of flocculant distribution within the flocculation zone. This can easily lead to excessively high or low concentrations of the floc, affecting floc growth and aggregation. Consequently, the resulting flocs are small and loose, reducing the efficiency of subsequent flotation or sedimentation separation. Furthermore, existing stirring devices in the flocculation zone mostly use a single rotating paddle, resulting in a single stirring direction. This makes it difficult to create multi-dimensional cross-mixing along the wastewater flow direction, and the flocs are easily broken up by the paddle, affecting the flocculation effect.

[0004] In the flotation separation stage, traditional scum scraping devices typically use chain-type or traveling scrapers that move in a straight reciprocating motion along the length of the tank to scrape the scum on the water surface into the scum discharge trough. The scraping direction is unidirectional, and there are blind spots in the scraping of scum that is unevenly distributed on the water surface. It is difficult to completely remove the scum, and some scum will remain on the water surface for a long time, gradually breaking down and sinking, affecting the quality of the effluent and greatly reducing the treatment effect of mouthwash production wastewater. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a mouthwash production wastewater treatment device.

The arc-shaped feeding disc swings back and forth in the direction of wastewater flow to sprinkle and cover the injected flocculant. The moving plate is also equipped with an interlacing mixing component, which is used to pull and stir the sewage in the direction of flow laterally. The arc-shaped stirring plate in the interlacing mixing component stirs the sewage and flocculant in the flocculation zone to mix and disperse them. The treatment tank is equipped with a shoveling separation component in the flotation zone. The shoveling separation component is used to move the scum to the slag discharge zones on both sides. The shoveling separation component includes a U-shaped push plate. Fixed partitions are fixedly installed on both sides of the flotation zone. The arc-shaped shoveling plate in the shoveling separation component drives the separation plate to move in a fan shape at the top of the flotation zone, stripping the scum at the top of the flotation zone to the slag discharge zone.

The output ends of the L-shaped sewage pipe and the L-shaped coagulant pipe are located on the top two sides of the shaking cylinder. Sewage and coagulant liquid are injected into the shaking cylinder for mixing and shaking.

[0009] As a preferred embodiment of the present invention, the treatment tank is provided with a first overflow plate between the coagulation zone and the flocculation zone. The dispersing feed assembly also includes a limiting base, which is fixedly installed in the width direction of the treatment tank.

[0010] A motor frame is fixedly installed on the top of the treatment tank, and a second motor is fixedly installed at the center of the motor frame. A rotating shaft is fixedly installed at the output end of the second motor. Several spray holes are evenly opened at the bottom of the arc-shaped spraying plate.

The output end of the L-shaped flocculation pipe is located at the top of the arc-shaped spraying plate. Drainage pipes are installed on both sides of the bottom of the flocculation zone of the treatment tank.

[0011] As a preferred embodiment of the present invention, the interleaved mixing assembly further includes an incomplete gear, which is fixedly installed at the bottom of the rotating shaft and engages movably with the rack frame. Arc-shaped movable plates are fixedly installed at both ends of the moving plate, and an arc-shaped stirring plate is fixedly installed at the bottom of the arc-shaped movable plate. Several stirring blades are fixedly installed at the bottom of the rotating shaft and move at the bottom of the rack frame.

[0012] As a preferred embodiment of the present invention, a second overflow plate is fixedly installed between the flocculation zone and the flotation zone in the treatment tank. A support plate is fixedly installed at the top center of the second overflow plate, and a drive frame is fixedly installed on the support plate. The drive frame is located at the top center of the flotation zone. A servo motor is fixedly installed at one end of the drive frame, and a screw is fixedly installed at the output end of the servo motor. A movable block is threaded through the screw. An arc-shaped connecting block is fixedly installed at the bottom of the movable block, and the top of the arc-shaped connecting block passes through a drive groove opened at the bottom of the drive frame. A limit rod is fixedly installed inside the drive frame, and both ends of the movable block move through the limit rod.

[0013] The loop-shaped push plate is fixedly installed at the bottom of the arc-shaped connecting block. The actuating separation assembly also includes an arc-shaped driving rod. A fixed rotating rod is fixedly installed on the top of the fixed partition. The arc-shaped actuating plate moves on the top of the fixed rotating rod. A separation plate is fixedly installed on the side of the arc-shaped actuating plate near the support plate. An arc-shaped driving rod is fixedly installed on the top of the end of the arc-shaped actuating plate away from the fixed rotating rod. The arc-shaped driving rod moves inside the loop-shaped push plate.

[0014] The U-shaped push plate has an arc-shaped push rod fixedly installed at the center of the side away from the support plate. The bottom of the arc-shaped actuating plate, the separation plate and the arc-shaped push rod are all provided with arc-shaped scrapers. The arc-shaped scrapers at the bottom of the separation plate scrape the scum in the flotation zone to the scum discharge area on the side of the fixed partition. The treatment tank is provided with an outlet pipe at the bottom of the flotation zone. The treatment tank is also provided with a dissolved air releaser at the bottom of the flotation zone. The dissolved air releaser releases microbubbles at the bottom of the flotation zone.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are: In this invention, the combination of the arc-shaped rocking arm and the multi-degree-of-freedom hinge structure in the mixing and shaking assembly causes the shaking cylinder to move in a conical circular oscillation trajectory. This generates a continuous and irregular turbulent effect between the wastewater and coagulant within the shaking cylinder, significantly enhancing the mixing intensity and contact area of ​​the liquid. This ensures that the coagulant quickly completes the charge neutralization reaction with the colloidal particles in the wastewater, improving the coagulation and destabilization efficiency. Simultaneously, the drainage holes around the bottom of the shaking cylinder allow the mixed wastewater to flow out evenly, avoiding short-circuiting and creating favorable conditions for subsequent flocculation reactions.

[0016] In this invention, the alternating meshing of the incomplete gears and the rack frame of the dispersing feed assembly drives the moving plate to reciprocate linearly along the T-shaped slide, thereby causing the arc-shaped sprinkling disc to swing back and forth in the direction of sewage flow. The sprinkling holes at the bottom of the arc-shaped sprinkling disc allow the flocculant to be dispersed and sprinkled in a curtain-like manner, and the swinging direction of the sprinkling disc is perpendicular to the direction of sewage flow, achieving uniform coverage of the flocculant on the cross-section of the sewage. This effectively avoids the problem of uneven mixing caused by the flocculant falling into a certain local area, greatly increases the contact probability between the flocculant and the tiny flocs in the sewage, and improves the utilization rate of the flocculant and the uniformity of floc formation.

[0017] In this invention, while the incomplete gear drives the reciprocating motion of the rack frame, the interlaced mixing component drives the arc-shaped movable plates at both ends of the moving plate to move laterally back and forth. This causes the arc-shaped stirring plate to pull and stir the sewage laterally along the width of the treatment tank, effectively cutting the sewage flow direction. At the same time, the stirring blades at the bottom of the rotating shaft continuously rotate and stir the sewage in the lower part of the flocculation zone. Through the organic combination of lateral reciprocating motion and rotational motion, a multi-directional and multi-dimensional interlaced mixing effect is formed, ensuring that the flocculant and the destabilized micro-flocculations are in full contact and efficiently bridged and aggregated to form large and dense flocs, significantly improving the flocculation reaction effect.

[0018] In this invention, a servo motor drives a screw to move a movable block in a linear reciprocating motion. This motion, through the transmission and cooperation of a loop-shaped push plate and an arc-shaped drive rod, actuates the separation assembly, causing the arc-shaped push plate to swing in a fan shape around a fixed rotating rod. The separation plate, fixedly mounted on the arc-shaped push plate, moves synchronously with it, and its direction of movement is opposite to the direction of sewage flow. When the separation plate opens to both sides in a fan shape, the arc-shaped scraper at its bottom actively scrapes the scum on the top surface of the flotation zone to both sides, allowing the scum to pass over the fixed partition and enter the scum discharge zone. This reverse scraping design effectively utilizes the relative speed difference between the mechanical motion and the water flow direction, improving the scum removal efficiency and ensuring timely discharge of the scum.

[0019] In this invention, the arc-shaped scrapers at the bottom of the arc-shaped actuating plate and the arc-shaped push rod work in a clear division of labor and cooperate with the arc-shaped scrapers at the bottom of the separation plate. During the reverse retraction of the separation plate, the arc-shaped scrapers at the bottom of the arc-shaped actuating plate and the arc-shaped push rod can gather the scum scattered on the water surface towards the center along the direction of water flow, so that the dispersed scum merges and gathers, and concentrates the dispersed scum within the scraping range of the separation plate. The gathering effect effectively avoids the scum from being dispersed and remaining on the water surface in the flotation zone, improves the scum collection efficiency, and creates conditions for efficient discharge when the separation plate opens its fan shape again, forming a cyclical operation mode of "expanding and scraping out, gathering and converging".

[0020] In this invention, the zoning design of the treatment tank enables continuous and automated operation of the wastewater treatment process. The conical oscillating mixing in the coagulation zone, the reciprocating sprinkling and staggered stirring in the flocculation zone, and the fan-shaped agitation and scraping in the flotation zone are all connected by natural overflow through high and low position differences, eliminating the need for additional lifting equipment and avoiding the risk of floc being broken during transportation. The continuous reciprocating motion of the agitation separation component ensures that scum is removed in a timely manner, preventing an excessively thick scum layer from affecting the flotation effect. The overall structure is compact and the transmission is highly efficient, significantly improving the treatment efficiency and effluent quality stability of mouthwash production wastewater.

[0023] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a mouthwash production wastewater treatment device includes a treatment tank 10, which is divided into a coagulation zone 11, a flocculation zone 12, and an air flotation zone 13. A mixing and shaking assembly is installed in the coagulation zone 11 of the treatment tank 10. The mixing and shaking assembly stirs and mixes the wastewater with a coagulant, allowing the wastewater and coagulant to complete a coagulation reaction. The mixing and shaking assembly includes a shaking cylinder 20, which performs a conical circular oscillation within the coagulation zone 11. An arc-shaped motor plate 21 is fixedly installed at one end of the treatment tank 10 near the coagulation zone 11. The top of the arc-shaped motor plate 21... The motor cover 22 is fixedly installed. The hybrid rocking assembly also includes a U-shaped support plate 25 and a connecting plate 28. The bottom of the motor cover 22 is fixedly installed with the U-shaped support plate 25. The bottom of the U-shaped support plate 25 is movably connected to the U-shaped support plate 26 through a rotating shaft. The U-shaped support plate 26 is movably connected to the connecting cylinder 27 through a rotating shaft. The first motor 23 is fixedly installed inside the motor cover 22. The output end of the first motor 23 passes through the motor cover 22 through a rotating shaft and is fixedly installed with an arc-shaped rocker arm 24. The top of the connecting cylinder 27 is fixedly installed at the bottom of the arc-shaped rocker arm 24.

[0025] A connecting plate 28 is fixedly installed at the bottom of the connecting cylinder 27. The connecting plate 28 is fixedly installed at the top center of the shaking cylinder 20. Drainage holes 29 are opened around the bottom of the shaking cylinder 20. An L-shaped sewage pipe 14 and an L-shaped coagulant pipe 15 are fixedly installed at one end of the treatment tank 10 near the coagulation zone 11. The L-shaped sewage pipe 14 and the L-shaped coagulant pipe 15 are located on both sides of the treatment tank 10. The output ends of the L-shaped sewage pipe 14 and the L-shaped coagulant pipe 15 are located on the top sides of the shaking cylinder 20. Sewage and coagulant liquid are injected into the shaking cylinder 20 for mixing and shaking.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In the coagulation zone 11, a mixing and shaking assembly is used to achieve thorough mixing and coagulation reaction between wastewater and coagulant. A first motor 23 is fixedly installed inside a motor housing 22, and its output end drives an arc-shaped rocker arm 24 to rotate in a circular motion via a rotating shaft. A connecting cylinder 27 is connected to the bottom of the arc-shaped rocker arm 24 via a rotating shaft. The top of the connecting cylinder 27 moves synchronously with the arc-shaped rocker arm 24, while the bottom of the connecting cylinder 27 is fixedly connected to a shaking cylinder 20 via a connecting plate 28. Since the rotation trajectory of the arc-shaped rocker arm 24 is circular, and the connecting cylinder 27 is connected to the U-shaped support plate 26 and the U-shaped support plate 25 via a rotating shaft... The multi-degree-of-freedom hinged structure allows the shaking cylinder 20 to move not simply by rotating, but by oscillating in a conical circular motion. At the same time, the L-shaped sewage pipe 14 and the L-shaped coagulant pipe 15 inject sewage and coagulant into the top of the shaking cylinder 20 from both sides of the treatment tank 10, respectively. The two liquids are subjected to continuous and irregular conical oscillation within the shaking cylinder 20, generating strong turbulence and mixing effects. This causes the coagulant to rapidly undergo a charge neutralization reaction with the colloidal particles in the sewage, completing coagulation and destabilization. The sewage in the coagulation zone 11 automatically flows into the flocculation zone 12 through the height difference of the first overflow plate 17.

[0027] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The treatment tank 10 is equipped with a dispersing feed assembly in the flocculation zone 12. The dispersing feed assembly is used to evenly spray flocculant into the coagulated wastewater. The dispersing feed assembly includes an arc-shaped spraying disc 36 and a moving plate 33. The arc-shaped spraying disc 36 swings back and forth in the direction of wastewater flow to spray and cover the injected flocculant. The treatment tank 10 is equipped with a first overflow plate 17 between the coagulation zone 11 and the flocculation zone 12. The dispersing feed assembly also includes a limiting base 30. The limiting base 30 is fixedly installed in the width direction of the treatment tank 10. The limiting base 30 has a T-shaped groove 31. A T-shaped slider 32 is slidably connected in the T-shaped groove 31. The T-shaped slider 32 is fixedly installed on both sides of the moving plate 33. A toothed rack frame 43 is fixedly installed at the bottom of the moving plate 33. Arc-shaped connecting rods 46 are fixedly installed around the top of the moving plate 33. The arc-shaped spraying disc 36 is fixedly installed at the top of the arc-shaped connecting rods 46. The arc-shaped spraying disc 36 moves on both sides of the top of the moving plate 33.

[0028] A motor frame 34 is fixedly installed on the top of the treatment tank 10. A second motor 35 is fixedly installed at the center of the motor frame 34. A rotating shaft 41 is fixedly installed at the output end of the second motor 35. Several spray holes 37 are evenly opened at the bottom of the arc-shaped spraying plate 36. L-shaped flocculation pipes 38 are staggered at the top of the flocculation zone 12 in the treatment tank 10. The output end of the L-shaped flocculation pipes 38 is located at the top of the arc-shaped spraying plate 36. Drainage pipes 39 are provided on both sides of the bottom of the flocculation zone 12 in the treatment tank 10.

[0029] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In the flocculation zone 12, a dispersing feed assembly and an interleaving mixing assembly are provided. These two components work together to achieve uniform flocculant addition and efficient mixing. A second motor 35 is fixedly mounted on a motor frame 34, and its output drives a rotating shaft 41 to rotate. An incomplete gear 42 is fixedly mounted at the bottom of the rotating shaft 41. The moving plate 33 in the dispersing feed assembly is slidably connected to the T-shaped groove 31 of the limiting base 30 via T-shaped sliders 32 on both sides. A circular rack frame 43 is fixed to the bottom of the moving plate 33. When the incomplete gear 42 rotates with the rotating shaft 41, it alternately meshes with the circular rack frame 43. When the teeth of the incomplete gear 42 contact the racks on both sides of the circular rack frame 43... The drive plate 33 moves in a reciprocating linear motion along the T-shaped chute 31. The reciprocating motion of the drive plate 33 is transmitted to the arc-shaped spraying plate 36 through the arc-shaped connecting rods 46 around its top, causing the arc-shaped spraying plate 36 to swing back and forth in the direction of sewage flow. The output end of the L-shaped flocculation pipe 38 is located at the top of the arc-shaped spraying plate 36. After the flocculant is continuously injected into the arc-shaped spraying plate 36, it is dispersed and sprayed onto the water surface of the flocculation zone 12 in a curtain-like manner through the spraying holes 37 evenly opened at the bottom of the arc-shaped spraying plate 36 during the swinging process. This achieves uniform coverage of the flocculant in the direction of sewage flow, and the movement direction of the arc-shaped spraying plate 36 is perpendicular to the direction of sewage flow, which improves the flocculant injection effect.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The moving plate 33 is also equipped with an interlaced mixing component, which is used to laterally pull and stir the sewage in the direction of flow. The arc-shaped stirring plate 40 in the interlaced mixing component stirs the sewage and flocculant in the flocculation zone 12 to mix and disperse them. The interlaced mixing component also includes an incomplete gear 42, which is fixedly installed at the bottom of the rotating shaft 41. The incomplete gear 42 is movably meshed with the rack frame 43. Arc-shaped movable plates 44 are fixedly installed at both ends of the moving plate 33. The arc-shaped stirring plate 40 is fixedly installed at the bottom of the arc-shaped movable plate 44. Several stirring blades 45 are fixedly installed at the bottom of the rotating shaft 41. The stirring blades 45 move at the bottom of the rack frame 43.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6While the dispersing feed assembly reciprocates and sprays the material, the interleaving mixing assembly works synchronously. During the reciprocating motion of the incomplete gear 42 driving the rack frame 43, the arc-shaped movable plates 44 fixedly installed at both ends of the moving plate 33 move laterally back and forth. An arc-shaped stirring plate 40 is fixedly installed at the bottom of the arc-shaped movable plate 44, causing the arc-shaped stirring plate 40 to move laterally along the width of the treatment tank 10 within the flocculation zone 12, thus laterally cutting the wastewater flow direction and ensuring sufficient contact between the flocculant and the tiny flocs in the wastewater. In addition, several stirring blades 45 are fixedly installed at the bottom of the rotating shaft 41. The stirring blades 45 are located at the bottom of the rack frame 43 and rotate continuously under the drive of the rotating shaft 41 to stir and disperse the sewage in the lower part of the flocculation zone 12 vertically. The combination of the lateral reciprocating motion of the arc-shaped stirring plate 40 and the rotational motion of the stirring blades 45 forms a multi-directional and multi-dimensional cross-mixing effect, ensuring that the flocculant and the destabilized micro flocs are in full contact and bridged and aggregated to form large and dense flocs.

[0032] See Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 The treatment tank 10 is equipped with a shoveling separation component in the flotation zone 13. The shoveling separation component is used to shove the scum to the discharge zones 67 on both sides. The shoveling separation component includes a U-shaped push plate 60. Fixed partitions 16 are fixedly installed on both sides of the flotation zone 13. The arc-shaped push plate 63 in the shoveling separation component drives the separation plate 64 to move in a fan shape at the top of the flotation zone 13, peeling the scum at the top of the flotation zone 13 to the discharge zone 67.

A screw 54 is fixedly installed at the output end of the servo motor 53. A movable block 55 is threaded through the screw 54. An arc-shaped connecting block 56 is fixedly installed at the bottom of the movable block 55. The top of the arc-shaped connecting block 56 passes through the drive groove 57 opened at the bottom of the drive frame 52. A limit rod 58 is fixedly installed inside the drive frame 52. Both ends of the movable block 55 move through the limit rod 58.

A fixed rotating rod 62 is fixedly installed on the top of the fixed partition 16. The arc-shaped actuating plate 63 is movable on the top of the fixed rotating rod 62. A separation plate 64 is fixedly installed on the side of the arc-shaped actuating plate 63 near the support plate 51. An arc-shaped driving rod 61 is fixedly installed on the top of the end of the arc-shaped actuating plate 63 away from the fixed rotating rod 62. The arc-shaped driving rod 61 is movable inside the U-shaped push plate 60.

[0034] An arc-shaped push rod 65 is fixedly installed at the center of the side of the U-shaped push plate 60 away from the support plate 51. Arc-shaped scraper 66 is provided at the bottom of the arc-shaped actuating plate 63, the separation plate 64 and the arc-shaped push rod 65. The arc-shaped scraper 66 at the bottom of the separation plate 64 scrapes the scum of the flotation zone 13 to the scum discharge zone 67 on the side of the fixed partition plate 16. The treatment tank 10 is provided with an outlet pipe 18 at the bottom of the flotation zone 13. The treatment tank 10 is provided with a dissolved air releaser at the bottom of the flotation zone 13. The dissolved air releaser releases microbubbles at the bottom of the flotation zone 13.

[0035] See Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9In the flotation zone 13, microbubbles are released at the bottom of the tank by a dissolved air releaser. The bubbles adhere to the flocs to form scum and float to the surface. The agitator separation component actively moves the scum to the scum discharge zones 67 on both sides. The servo motor 53 is fixedly installed at one end of the drive frame 52, and its output end drives the screw 54 to rotate. The movable block 55 is threaded through the screw 54 and its two ends pass through the limit rod 58. When the screw 54 rotates, the movable block 55 moves linearly back and forth along the limit rod 58. The bottom of the movable block 55 is fixedly connected to the U-shaped push plate 60 through the arc-shaped connecting block 56. The U-shaped push plate 60 moves linearly synchronously with the movable block 55. The arc-shaped agitator 63 is movably mounted through the fixed rotating rod 62. Mounted on the top of the fixed partition 16, it can swing in a fan shape around the fixed rotating rod 62; the arc-shaped actuating plate 63 has a separation plate 64 fixedly installed on the side near the support plate 51, and an arc-shaped driving rod 61 fixedly installed on the top of the end away from the fixed rotating rod 62, and the arc-shaped driving rod 61 is movably inserted inside the loop-shaped push plate 60; when the loop-shaped push plate 60 moves in a straight line, its inner wall pushes the arc-shaped driving rod 61, forcing the arc-shaped actuating plate 63 to swing in a fan shape around the fixed rotating rod 62; at the same time, an arc-shaped push rod 65 is fixedly installed at the center of the side of the loop-shaped push plate 60 away from the support plate 51, and the arc-shaped push rod 65 moves synchronously with the loop-shaped push plate 60, pushing the arc-shaped actuating plate 63 on the other side. 3. Synchronous swinging, thereby realizing the linkage of the two-sided actuation components; the bottom of the arc-shaped actuation plate 63, the separation plate 64, and the arc-shaped push rod 65 are all equipped with arc-shaped scrapers 66, and the three have clear division of labor and cooperate in the movement process; the arc-shaped scrapers 66 at the bottom of the separation plate 64 make a fan-shaped opening and closing movement under the drive of the arc-shaped actuation plate 63, and the running direction of the separation plate 64 is opposite to the sewage flow direction; when the separation plate 64 opens to both sides in a fan shape, the arc-shaped scrapers 66 at its bottom actively scrape the scum on the top water surface of the flotation zone 13 to both sides, so that the scum crosses the fixed partition 16 and enters the scum discharge zone 67 to complete the discharge of scum; while the bottom of the arc-shaped actuation plate 63 and the bottom of the arc-shaped push rod 65 The arc-shaped scraper 66 mainly serves to gather the scum. During the reverse retraction of the separation plate 64, these two sets of scrapers can gather the scum scattered on the water surface towards the center along the direction of water flow, causing the scum to merge back and forth, so that the dispersed scum is concentrated within the scraping range of the separation plate 64, making it easier to discharge efficiently when the fan shape opens again. The entire agitation process is a continuous reciprocating motion. When the separation plate 64 fan-shaped opens, it scrapes off the scum. When the fan shape closes, the scraper at the bottom of the arc-shaped agitator 63 and the arc-shaped push rod 65 gathers and collects the scum. This cycle repeats to ensure that the scum is removed in a timely and thorough manner, avoiding an excessively thick scum layer that would affect the subsequent air flotation effect. The treated clean water is discharged through the outlet pipe 18 at the bottom of the air flotation zone 13. The air flotation process is an existing mature structure and is not described in detail in the application. The model of the air flotation machine can be the TJ type air flotation machine from Wuxi Zhengben Qingyuan Equipment Technology Co., Ltd.

[0036] Working principle: In the coagulation zone 11, the mixing and shaking assembly is used to achieve full mixing and coagulation reaction of sewage and coagulant; the core motion mechanism of the mixing and shaking assembly is driven by the first motor 23; the first motor 23 is fixed inside the motor cover 22, and its output end drives the arc-shaped rocker arm 24 to rotate in a circular motion through the rotating shaft; the bottom of the arc-shaped rocker arm 24 is connected to the connecting cylinder 27 through the rotating shaft, the top of the connecting cylinder 27 moves synchronously with the arc-shaped rocker arm 24, and the bottom of the connecting cylinder 27 is fixedly connected to the shaking cylinder 20; since the rotation trajectory of the arc-shaped rocker arm 24 is circular, the connecting cylinder 27 and the U-shaped support plate 26 and the U-shaped support plate 25 form a multi-degree-of-freedom hinge structure through the rotating shaft. This causes the shaking drum 20 to move not simply by rotating, but by moving in a conical circular oscillation trajectory. At the same time, the L-shaped sewage pipe 14 and the L-shaped coagulant pipe 15 inject sewage and coagulant into the top of the shaking drum 20 from both sides of the treatment tank 10, respectively. The two liquids are subjected to continuous and irregular conical oscillation in the shaking drum 20, generating strong turbulence and mixing effects, which causes the coagulant to quickly react with the colloidal particles in the sewage to neutralize the charge and complete the coagulation and destabilization. The mixed sewage flows out evenly into the coagulation zone through the drainage holes 29 opened around the bottom of the shaking drum 20, and the sewage in the coagulation zone flows into the flocculation zone 12 automatically through the height difference of the first overflow plate 17.

[0037] The second motor 35 is fixedly mounted on the motor frame 34, and its output end drives the rotating shaft 41 to rotate. An incomplete gear 42 is fixedly mounted on the bottom of the rotating shaft 41. The moving plate 33 in the shaking and feeding assembly is slidably connected to the T-shaped groove 31 of the limiting base 30 via T-shaped sliders 32 on both sides. A circular rack frame 43 is fixed to the bottom of the moving plate 33. When the incomplete gear 42 rotates with the rotating shaft 41, it alternately meshes with the circular rack frame 43. When the teeth of the incomplete gear 42 contact the racks on both sides of the circular rack frame 43, it drives the moving plate 33 to reciprocate linearly along the T-shaped groove 31. The reciprocating motion of the moving plate 33 is achieved through… The arc-shaped connecting rods 46 around its top transmit power to the arc-shaped spraying disc 36, causing the arc-shaped spraying disc 36 to swing back and forth in the direction of sewage flow. The output end of the L-shaped flocculation pipe 38 is located at the top of the arc-shaped spraying disc 36. After the flocculant is continuously injected into the arc-shaped spraying disc 36, it is dispersed and sprayed onto the water surface of the flocculation zone 12 in a curtain-like manner through the evenly opened spraying holes 37 at the bottom of the arc-shaped spraying disc 36 during the swinging process. This achieves uniform coverage of the flocculant in the direction of sewage flow, avoiding uneven mixing caused by concentrated addition. Moreover, the movement direction of the arc-shaped spraying disc 36 is perpendicular to the direction of sewage flow, which greatly improves the effect of flocculant injection.

[0038] While the dispersing feed component is reciprocating and sprinkling the material, the interleaving mixing component works synchronously. During the reciprocating motion of the rack frame 43 driven by the incomplete gear 42, the arc-shaped movable plates 44 fixed at both ends of the moving plate 33 move laterally. An arc-shaped stirring plate 40 is fixedly installed at the bottom of the arc-shaped movable plate 44. Therefore, the arc-shaped stirring plate 40 moves laterally along the width of the treatment tank 10 within the flocculation zone 12, horizontally cutting the wastewater flow direction, allowing the flocculant to fully contact the tiny flocs in the wastewater. In addition, several stirring blades 45 are fixedly installed at the bottom of the rotating shaft 41. The stirring blades 45 are located at the bottom of the rack frame 43 and rotate continuously under the drive of the rotating shaft 41 to stir and disperse the sewage in the lower part of the flocculation zone 12 vertically. The combination of the lateral reciprocating motion of the arc-shaped stirring plate 40 and the rotational motion of the stirring blades 45 forms a multi-directional and multi-dimensional cross-mixing effect, ensuring that the flocculant and the destabilized micro flocs are in full contact and bridged and aggregated to form large and dense flocs.

[0039] The air flotation zone 13 is used to achieve solid-liquid separation. Microbubbles are released at the bottom of the tank through the dissolved air releaser. The bubbles adhere to the floc to form scum and float to the water surface. The agitator separation component is used to actively move the scum to the scum discharge zones 67 on both sides.

[0040] The servo motor 53 is fixedly installed at one end of the drive frame 52, and its output end drives the screw 54 to rotate. The movable block 55 is threaded through the screw 54, and both ends are threaded through the limit rod 58. Therefore, when the screw 54 rotates, the movable block 55 moves linearly back and forth along the limit rod 58. The bottom of the movable block 55 is fixedly connected to the loop push plate 60 through the arc-shaped connecting block 56. The loop push plate 60 moves linearly synchronously with the movable block 55.

[0041] In the air flotation zone 13, the arc-shaped actuating plate 63 is movably mounted on the top of the fixed partition 16 via the fixed rotating rod 62, and can swing in a fan shape around the fixed rotating rod 62. A separation plate 64 is fixedly installed on the side of the arc-shaped actuating plate 63 near the support plate 51, and an arc-shaped driving rod 61 is fixedly installed on the top of the end away from the fixed rotating rod 62, and the arc-shaped driving rod 61 is movably inserted inside the loop-shaped push plate 60. When the loop-shaped push plate 60 moves in a straight line, its inner wall pushes the arc-shaped driving rod 61, forcing the arc-shaped actuating plate 63 to swing in a fan shape around the fixed rotating rod 62. At the same time, an arc-shaped push rod 65 is fixedly installed at the center of the side of the loop-shaped push plate 60 away from the support plate 51. The arc-shaped push rod 65 moves synchronously with the loop-shaped push plate 60, pushing the arc-shaped actuating plate 63 on the other side to swing synchronously, thereby realizing the linkage of the actuating components on both sides.

[0042] The bottom of the arc-shaped actuating plate 63, the separation plate 64, and the arc-shaped push rod 65 are all equipped with arc-shaped scrapers 66. These three components work in a clear division of labor and cooperate effectively during operation. The arc-shaped scrapers 66 at the bottom of the separation plate 64, driven by the arc-shaped actuating plate 63, perform a fan-shaped opening and closing motion, with the separation plate 64 moving in the opposite direction to the sewage flow. When the separation plate 64 opens to both sides in a fan shape, the arc-shaped scrapers 66 at its bottom actively move the scum on the water surface at the top of the flotation zone 13 towards... The scraping action on both sides causes the scum to pass over the fixed partition 16 and enter the scum discharge area 67, completing the discharge of the scum. The arc-shaped scraper 66 at the bottom of the arc-shaped agitator 63 and the arc-shaped push rod 65 mainly serves to gather the scum. During the reverse retraction of the separation plate 64, these two sets of scraper blades can gather the scum scattered on the water surface towards the center along the direction of water flow, causing the scum to merge back and forth, so that the dispersed scum is concentrated within the scraping range of the separation plate 64, making it easier to discharge efficiently when the fan-shaped opening occurs next time.

[0043] The entire agitation process is a continuous reciprocating motion; when the separation plate 64 expands in a fan shape, it scrapes off the scum; when the fan shape closes, the scraper at the bottom of the arc-shaped agitation plate 63 and the arc-shaped push rod 65 gathers and collects the scum. This cycle repeats to ensure that the scum is removed in a timely and thorough manner, and to avoid the scum layer being too thick and affecting the subsequent air flotation effect; the treated clean water is discharged through the water outlet pipe 18 at the bottom of the air flotation zone 13.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
