Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and specifically to a sewage treatment device with a dosing function. Background Art

[0002] Water treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, and catering. It has also increasingly entered the daily lives of ordinary people. The upstream suppliers in the sewage treatment industry are mainly manufacturers of sewage treatment equipment and suppliers of sewage treatment chemicals, both of which belong to industries with relatively fast development and good demand conditions.

[0003] In the existing sewage treatment device, during the primary sedimentation of sewage, a flocculant is added and mixed with the sewage inside the sedimentation tank. However, there are often floating scum covering the surface of the sewage in the sedimentation tank, forming an isolation layer that hinders the diffusion of the flocculant solution from the dosing point to the main body of the sewage. At the same time, due to the obstruction of the floating scum, the flocculant may accumulate locally in the area near the floating scum, while the concentration is relatively low in the area far from the floating scum, resulting in uneven distribution of the flocculant concentration in the sewage. This concentration difference will cause the flocculation reaction to proceed differently in different areas, affecting the consistency of the flocculation effect. Therefore, we provide a sewage treatment device with a dosing function to solve the above problems. Summary of the Invention

[0012] As a further solution of the present invention: An impact rod is fixedly connected to the side wall of the rotating rod. An arc spring is installed between the rotating rod and the auxiliary rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the cooperation of components such as the fixed rod, after the pretreatment equipment preliminarily treats the sewage, the pretreatment equipment conveys the preliminarily treated sewage from the underground pipeline to the inside of the sedimentation tank. Then, the sewage is sedimented in the sedimentation tank. At the same time, the flocculant can be conveyed into the dosing tank through an external dosing pipe and mixed with the sewage inside the sedimentation tank through the water outlet tank. At the same time, the servo motor drives the rotating column to rotate and throw out the flocculant inside so that it can flow out from the top to the bottom into the sewage, so that the sewage can be mixed with the flocculant. At the same time, it is avoided that the flocculant is added to the sewage from the top of the sewage, thereby reducing the excessive contact between the flocculant and the scum in the sewage. Furthermore, the flocculant and the sewage are more evenly mixed, and can more fully undergo a flocculation reaction with the suspended particles in the sewage, making the suspended particles coagulate into larger flocs faster and more effectively, thereby improving the sedimentation efficiency, contributing to the subsequent removal of pollutants in the sewage, and enhancing the sewage treatment effect; 2. By setting the cooperation of components such as the aggregate hopper, when the scum layer is too thick, the lower scum naturally sinks due to density difference and directly enters the opening range of the aggregate hopper, forming a collection mode of skimming on the water surface and intercepting underwater, thereby improving the cleaning effect of the scum. When the aggregate hopper pours the accumulated scum inside into the slag discharge port, the fixed rod continues to drive the connecting rod to rotate in a circle. When the first spherical rod separates from the first abutting plate, under the action of the auxiliary spring and the torsion spring, the connecting rod and the aggregate hopper are restored to their original positions at the same time to continue collecting scum, so that when the aggregate hopper moves to the highest point of the first abutting plate, the opening is aligned with the slag discharge port to pour out all the scum, so as to clean the scum in the sewage, and then enable the flocculant to fully mix with the sewage, reduce the interference of the scum, make the concentration distribution of the flocculant in the sewage uniform, and further improve the sewage treatment effect; 3. By setting the cooperation of components such as the protective shell, when the aggregate hopper pours the collected scum into the slag discharge port and rotates on the limit seat, the protective shell also rotates with the aggregate hopper. When the first spherical rod moves to the highest point of the first abutting plate, the third spherical rod abuts against the second abutting plate, thereby pushing the third spherical rod to drive the second straight rack to move inside the protective shell. Since the second straight rack meshes with the second spur gear, the second spur gear is driven to rotate, and a plurality of dirt-proof filter plates are driven to rotate at the same time, so that the top of the dirt-proof filter plate faces the outside of the aggregate hopper to remove the blockage of the scum, so that the scum can be poured into the slag discharge port. Thus, when the aggregate hopper rotates during slag discharge, the dirt-proof filter plates rotate synchronously, so that the opening directions of the dirt-proof filter plates and the aggregate hopper are the same, preventing the dirt-proof filter plates from blocking the scum and causing the scum to be unable to be discharged, thereby improving the overall slag discharge effect of the device; 4. By setting the cooperation of components such as the guide frame, when the second spherical rod drives the auxiliary slider to move upward inside the auxiliary slide seat and drives the guide frame to rotate on the auxiliary seat, the inclination angle of the guide frame is adjusted. When the second spherical rod moves to the highest point of the abutting block, the inclination angle of the guide frame increases, thereby accelerating the flow rate of the scum and improving the collection efficiency of the scum. When the second spherical rod moves from the highest point of the abutting block to the lowest point, under the action of the auxiliary spring, the second spherical rod is restored to its original position, so that the bottom of the second spherical rod continues to fit on the top of the circular slideway and rotates. The cleaning radius of the guide frame covers the entire sedimentation tank, eliminating the collection blind area of traditional equipment, collecting the scum far from the slag discharge port through the guide frame and then transporting it into the aggregate hopper, thereby improving the collection efficiency of the scum; 5. By setting the cooperation of components such as the large gear, when the meshing teeth of the large gear mesh with the small gear, the large gear drives the small gear to rotate a certain angle, so that the small gear drives the rotating rod to rotate through the first shaft rod, thereby dialing the scum on the water surface between the fixed rod and the auxiliary rod, so as to achieve the aggregation efficiency of the scum and improve the collection efficiency of the scum; 6. By setting the cooperation of parts such as the arc-shaped spring, when the meshing teeth of the large gear separate from the small gear, the rotating rod is driven to return to its original position under the action of the arc-shaped spring. Since there will be a certain impact force when the arc-shaped spring drives the rotating rod to reset, when the impact rod contacts the auxiliary rod, the auxiliary rod will vibrate, and then the fixed rod and the connecting rod will resonate. The resonance of the fixed rod and the connecting rod is transmitted to the material guiding groove and the aggregate hopper, which can effectively break the adhesion force between the floating slag and the surface of the equipment, thus greatly improving the slag discharge efficiency.

[0018] Please refer toFigures 1 to 10 In this embodiment, a sewage treatment device with a chemical dosing function is provided, including: a pretreatment device 1. The outlet end of the pretreatment device 1 is connected to a plurality of sedimentation tanks 2 through underground pipelines. A rotating column 3 is installed inside the sedimentation tank 2. The rotating column 3 includes a chemical dosing tank 50 and a water outlet tank 49. Chemicals are dosed into the sedimentation tank 2 through the water outlet tank 49. A slag discharge channel 5 and a slag discharge port 6 are fixedly connected to the inner wall of the sedimentation tank 2, and the slag discharge channel 5 is fixedly connected to one side of the slag discharge port 6. The discharge port of the slag discharge port 6 is externally connected to a slag discharge device through a pipeline. An aggregate unit, a material guiding mechanism, and an auxiliary component are respectively arranged on the outer wall of the rotating column 3. The aggregate unit includes a fixing rod 10 fixedly connected to the outer wall of the rotating column 3. One end of the fixing rod 10 is provided with a connecting rod 11. Two limiting seats 28 are fixedly connected to the bottom of the connecting rod 11. An aggregate hopper 43 is arranged inside the two limiting seats 28, and the length of the aggregate hopper 43 is less than the inner diameter of the slag discharge channel 5. A second shaft rod 42 is fixedly connected to each end of the aggregate hopper 43. The aggregate hopper 43 is rotationally connected to the limiting seat 28 through the second shaft rod 42. A plurality of filter holes are formed inside the aggregate hopper 43. One end of the two second shaft rods 42 penetrates to the outside of the limiting seat 28 and is respectively fixedly connected to a circular plate 29 and a first straight gear 33. A torsion spring 30 is respectively installed between the circular plate 29, the first straight gear 33 and the limiting seat 28. The aggregate unit further includes an auxiliary plate 41 fixedly connected to one end of the fixing rod 10. Two trapezoidal slideways 24 are fixedly connected to the top of the auxiliary plate 41. A trapezoidal slider 25 is slidably connected to the inside of each of the two trapezoidal slideways 24. The side wall of the trapezoidal slider 25 is fixedly connected to one end of the connecting rod 11. One end of the connecting rod 11 is fixedly connected to a rectangular plate 26. A plurality of power springs 27 are installed between the rectangular plate 26 and the auxiliary plate 41. A first spherical rod 31 is fixedly connected to the bottom of the limiting seat 28. A first abutting plate 7 for abutting against the first spherical rod 31 is fixedly connected to the top of the slag discharge port 6. A first straight rack 32 meshing with the first straight gear 33 is fixedly connected to the bottom of the auxiliary plate 41; The pretreatment device 1 completes the pretreatment stage of sewage under the cooperation of facilities such as a grille and a grit chamber. Since it is a prior art, this solution is not described in detail in this scheme; The rotating column 3 realizes circumferential rotation under the cooperation of parts such as a servo motor and a driving gear. Since it is a prior art, this solution is not described in detail in this scheme; The chemical dosing tank 50 is opened at the top of the rotating column 3, and the inside of the rotating column 3 is set as a hollow structure. A plurality of water outlet tanks 49 communicating with the inside are opened on the outside of the rotating column 3. The chemical dosing tank 50 at the top of the rotating column 3 can be rotationally connected to an external chemical dosing pipe, so that the external chemical dosing pipe can be filled into the rotating column 3; After the pretreatment device 1 preliminarily treats the sewage, the pretreatment device 1 conveys the preliminarily treated sewage from the underground pipeline to the inside of the sedimentation tank 2, and then the sewage is sedimented through the sedimentation tank 2. At the same time, the flocculant can be conveyed into the dosing tank 50 through the external dosing pipe, and mixed with the sewage inside the sedimentation tank 2 through the water outlet tank 49. At the same time, the servo motor drives the rotating column 3 to rotate and throw out the internal flocculant so that it can flow out into the sewage from top to bottom, so that the sewage can be mixed with the flocculant, and at the same time, the flocculant is prevented from being added to the sewage from the top of the sewage, thereby reducing the excessive contact between the flocculant and the scum in the sewage, and further making the flocculant and the sewage mix more evenly, and can react with the suspended particles in the sewage more fully to cause flocculation, so that the suspended particles are aggregated into larger flocs faster and more effectively, thereby improving the sedimentation efficiency, contributing to the subsequent removal of pollutants in the sewage, and enhancing the sewage treatment effect; While the rotating column 3 rotates, it drives the fixed rod 10 to rotate, and at the same time drives the connecting rod 11 to push the scum on the sewage surface to rotate on the water surface. When there is too much scum, it will deposit underwater from the water surface. By rotating the fixed rod 10, the aggregate hopper 43 can be driven to rotate to collect the deposited scum. When the scum layer is too thick, the lower scum sinks naturally due to density difference and directly enters the opening range of the aggregate hopper 43, forming a collection mode of skimming on the water surface and intercepting underwater, thereby improving the cleaning effect of the scum; When the connecting rod 11 moves above the slag discharge channel 5, the first spherical rod 31 abuts against the inclined surface on one side of the slag discharge channel 5, thereby pushing the limit seat 28 to move upward, and driving the connecting rod 11 to move upward through the trapezoidal slider 25 inside the trapezoidal slideway 24. When the first spherical rod 31 moves to the top of the slag discharge channel 5, the top of the aggregate hopper 43 moves to the water surface, and the aggregate hopper 43 pushes the scum and collects the scum. Under the rotation of the connecting rod 11, the scum will be gathered inside the aggregate hopper 43, and the excess water will flow out from the filter holes on one side of the aggregate hopper 43. When the first spherical rod 31 abuts against the first abutting plate 7, it pushes the connecting rod 11 to move upward again. At this time, the first spur gear 33 meshes with the first rack 32, thereby driving the aggregate hopper 43 to rotate on the limit seat 28 through the first spur gear 33. When the first spherical rod 31 moves from the lowest point of the first abutting plate 7 to the highest point of the first abutting plate 7, the aggregate hopper 43 pours the scum gathered inside into the slag discharge port 6. Then the fixed rod 10 continues to drive the connecting rod 11 to rotate in a circle. When the first spherical rod 31 separates from the first abutting plate 7, under the action of the power spring 27 and the torsion spring 30, the connecting rod 11 and the aggregate hopper 43 are restored to their original positions at the same time to continue collecting scum, so that when the aggregate hopper 43 moves to the highest point of the first abutting plate 7, the opening is aligned with the slag discharge port 6 and all the scum is poured out, thereby improving the cleaning efficiency of the scum.

[0019] Please refer to Figures 1 to 10, a blocking component for blocking scum is arranged inside the aggregate hopper 43. The blocking component includes a protective shell 34 fixedly connected to one end of the aggregate hopper 43. A second straight rack 47 is arranged inside the protective shell 34. One side of the second straight rack 47 is fixedly connected with a slider. An auxiliary groove matching with the slider is arranged at one end of the aggregate hopper 43. The second straight rack 47 is slidably connected with the auxiliary groove through the slider. A third spherical rod 45 is fixedly connected to both ends of the second straight rack 47. One end of each third spherical rod 45 penetrates to the outside of the protective shell 34 and is slidably connected with the protective shell 34. A return spring 4 is installed between the second straight rack 47 and the protective shell 34. A second abutting plate 44 for abutting against the third spherical rod 45 is fixedly connected to the bottom of the connecting rod 11. A plurality of second straight gears 46 are meshed below the second straight rack 47. One side of each second straight gear 46 is fixedly connected with a rotating shaft, and one end of the rotating shaft penetrates to the inside of the aggregate hopper 43 and is fixedly connected with a dirt-blocking filter plate 21; When the aggregate hopper 43 pours the collected scum into the slag discharge port 6 and rotates on the limit seat 28, the protective shell 34 also rotates with the aggregate hopper 43. When the first spherical rod 31 moves to the highest point of the first abutting plate 7, the third spherical rod 45 abuts against the second abutting plate 44, thereby pushing the third spherical rod 45 to drive the second straight rack 47 to move inside the protective shell 34. Since the second straight rack 47 is meshed with the second straight gear 46, the second straight gear 46 is driven to rotate, and a plurality of dirt-blocking filter plates 21 are driven to rotate simultaneously, so that the top of the dirt-blocking filter plate 21 faces the outside of the aggregate hopper 43, releasing the blockage of the scum, so that the scum can be poured into the slag discharge port 6. Thus, while the aggregate hopper 43 rotates during slag discharge, the dirt-blocking filter plate 21 rotates synchronously, so that the dirt-blocking filter plate 21 is in the same opening direction as the aggregate hopper 43, preventing the dirt-blocking filter plate 21 from blocking the scum and causing the scum to be unable to be discharged, thereby improving the overall slag discharge effect of the device.

[0020] Please refer to Figures 2 to 10 , the material guiding mechanism includes an auxiliary seat 40 and an auxiliary sliding seat 35 fixedly connected to the bottom of the fixed rod 10. The auxiliary seat 40 is rotatably connected with a material guiding frame 20 through a rotating shaft. An auxiliary slider 37 is fixedly connected to the side wall of the material guiding frame 20. One end of the auxiliary slider 37 penetrates to the outside of the auxiliary sliding seat 35 and is fixedly connected with a second spherical rod 38, and the auxiliary slider 37 is slidably connected with the auxiliary sliding seat 35. A plurality of auxiliary springs 36 are installed between the auxiliary slider 37 and the fixed rod 10. A plurality of fixing frames 48 are fixedly connected to the bottom of the sedimentation tank 2. A circular slideway 8 is fixedly connected to the top of the fixing frame 48. A plurality of abutting blocks 9 are fixedly connected to the top of the circular slideway 8. The top of the abutting block 9 is provided with an inclined surface. A material guiding groove 39 is arranged inside the material guiding frame 20. The material guiding groove 39 is arranged at a high-low level. A fixing plate 22 is fixedly connected to one side of the aggregate hopper 43. A hose 23 is installed between the discharge port of the material guiding groove 39 and the feed port of the fixing plate 22; When the fixed rod 10 drives the connecting rod 11 to push the scum, the fixed rod 10 drives the guide frame 20 to rotate in a circle at the same time. While the guide frame 20 rotates, it can collect the scum away from the slag discharge port 6 and introduce it into the guide groove 39. Because the guide groove 39 is set one high and one low, the scum inside the guide groove 39 will flow from high to low, and then enter the hose 23 through the discharge port of the guide groove 39, and then enter the collecting hopper 43 through the fixed plate 22, thereby guiding the scum away from the slag discharge port 6, so that the collecting hopper 43 can collect the scum away from the slag discharge port 6. When the fixed rod 10 drives the guide frame 20 to rotate, it drives the second spherical rod 38 to rotate on the circular slide 8. When the bottom of the second spherical rod 38 moves along the lowest point to the highest point of the abutment block 9, it pushes the second spherical rod 38 to move. The spherical rod 38 drives the auxiliary sliding block 37 to move upward inside the auxiliary sliding seat 35, thereby driving the material guide frame 20 to rotate on the auxiliary seat 40, thereby adjusting the inclination angle of the material guide frame 20. When the second spherical rod 38 moves to the highest point of the abutment block 9, the inclination angle of the material guide frame 20 increases, thereby accelerating the flow rate of the scum and improving the efficiency of collecting the scum. When the second spherical rod 38 moves from the highest point to the lowest point of the abutment block 9, the second spherical rod 38 is restored to its original position under the action of the auxiliary spring 36, so that the bottom of the second spherical rod 38 continues to fit on the top of the circular slide 8 for rotation. The cleaning radius of the material guide frame 20 covers the entire sedimentation tank 2, eliminating the collection blind spot of traditional equipment, and the scum away from the slag discharge port 6 is collected by the material guide frame 20 and then transported to the inside of the collecting hopper 43, thereby improving the collection efficiency of the scum.

[0021] See also Figures 2 to 3 The auxiliary component includes an auxiliary rod 12 fixedly connected to one side of the fixed rod 10, a motor 16 is fixedly connected to the top of the auxiliary rod 12, a large gear 17 is fixedly connected to the execution end of the motor 16, one end of the auxiliary rod 12 is rotatably connected to a first shaft rod 18, one end of the first shaft rod 18 passes through the top of the auxiliary rod 12 and is fixedly connected to a small gear 19, and the small gear 19 is meshed with the large gear 17, the outer wall of the first shaft rod 18 is fixedly connected to a rotating rod 13, the side wall of the rotating rod 13 is fixedly connected to a striking rod 15, and an arc spring 14 is installed between the rotating rod 13 and the auxiliary rod 12; When the fixed rod 10 rotates, the auxiliary rod 12 is driven to rotate inside the sedimentation tank 2. The motor on the auxiliary rod 12 drives the large gear 17 to rotate. When the meshing teeth of the large gear 17 mesh with the small gear 19, the large gear 17 drives the small gear 19 to rotate a certain angle, so that the small gear 19 drives the rotating rod 13 to rotate through the first shaft 18, thereby moving the scum on the water surface between the fixed rod 10 and the auxiliary rod 12, thereby achieving the aggregation efficiency of the scum and improving the collection efficiency of the scum; Only a quarter of the meshing teeth of the large gear 17 are in contact. When the meshing teeth of the large gear 17 separate from the small gear 19, under the action of the arc spring 14, the rotating rod 13 is driven to return to its original position. Because there will be a certain impact force when the arc spring 14 drives the rotating rod 13 to reset, when the impact rod 15 contacts the auxiliary rod 12, the auxiliary rod 12 will vibrate, and then the fixed rod 10 and the connecting rod 11 will resonate. The resonance of the fixed rod 10 and the connecting rod 11 is transmitted to the material guiding groove 39 and the aggregate hopper 43, which can effectively break the adhesion force between the scum and the surface of the equipment, thus greatly improving the slag discharging efficiency. When the large gear 17 and the small gear 19 are in a separated state, the rotating rod 13 can stay still for a period of time. During this period, the water flow deflected by the rotating rod 13 can slowly settle, reducing the flow of the scum on the water surface. Then the large gear 17 meshes with the small gear 19 again. Repeating this process many times can make the scum adhering to the inside of the material guiding groove 39 and the aggregate hopper 43 fall off.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
