Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purification treatment, in particular to a decentralized domestic water disinfection and purification equipment and a purification method. BACKGROUND

[0002] Domestic water refers to water required for daily life, mainly taken from rivers, lakes or underground, and treated by processes such as flocculation, sedimentation, filtration and disinfection before being delivered to users by water distribution pump stations. Decentralized domestic water refers to a small and modular water mode that independently completes the processes of "water taking, treatment, water use, tail water treatment and reuse or discharge" at the water use point (or nearby area) without relying on urban centralized water supply and drainage pipe networks.

[0003] In the flocculation stage, the flocculant is usually directly delivered to the flocculation cylinder through the pipeline, and the discharge position is concentrated. Mechanical power is required to generate turbulent flow for forced stirring to break the laminar flow state of the water flow and achieve dispersion of the flocculant. However, excessive turbulent shear force can cause the flocs to break, large flocs to tear into small flocs, and the settling velocity to decrease significantly. The small flocs that do not settle carry pollutants such as suspended solids, bacteria and heavy metal ions into subsequent work links, resulting in a dramatic increase in load and affecting the water quality.

[0023] The following is according toFigures 1-14 The present application provides a decentralized domestic water disinfection and purification device and a purification method.

[0024] In one aspect, the present application provides a decentralized domestic water disinfection and purification device.

[0025] Please refer to Figure 1 and Figure 2 The decentralized domestic water disinfection and purification device comprises a pretreatment tank 31, a flocculation tank 32, a sedimentation tank 33, an ozone tank 34, a filter tank 35 and a disinfection tank 36 arranged in sequence, and the flocculation tank 32 is fixedly connected with a waste tank 14 through a pipeline at the lower end. The raw water first enters the pretreatment tank 31 to remove impurities with a density greater than water under the action of gravity, complete rough purification, and the supernatant enters the flocculation tank 32; a flocculant is added to the flocculation tank 32 to mix with the raw water to make the fine suspended solids in the water coagulate into flocs, and the large, dense and good-sedimentation flocs settle to the bottom of the flocculation tank 32 and are discharged to the waste tank 14 through a pipeline, and the supernatant enters the sedimentation tank 33; part of the flocs will enter the sedimentation tank 33 with the water, and the sedimentation tank 33 is provided with an inclined plate inside, the flocs settle to the bottom of the sedimentation tank 33 under the action of gravity to form sludge, and the supernatant enters the ozone tank 34 through the inclined plate; ozone has fast sterilization speed and no residue, and can oxidize and decompose organic matter in water, and the treated water enters the filter tank 35; the filter tank 35 is paved with activated carbon and quartz sand to further intercept fine suspended solids, residual flocs and part of bacteria in water; the treated water enters the disinfection tank 36 to kill microorganisms in water, prevent bacteria from breeding during water supply, and ensure water safety and health, which is the last key process of water treatment.

[0026] Further, a flocculation cylinder 12 is arranged in the flocculation tank 32, the flocculation cylinder 12 is provided with a partition plate 321 outside, the partition plate 321 is fixedly connected with the inner wall of the flocculation tank 32, the partition plate 321 supports the flocculation cylinder 12 to make the upper and lower ends of the flocculation cylinder 12 be open, and the upper part of the flocculation tank 32 is fixedly provided with a support frame 1.

[0027] However, in actual flocculation work, the flocculant is usually directly delivered into the flocculation cylinder 12 through a pipeline, the discharge position is concentrated, and mechanical power is needed to generate turbulent flow for forced stirring to break the laminar flow state of water flow and realize the dispersion of the flocculant, but excessive turbulent shear force will cause the flocs to break, large flocs to tear into fine flocs, and the settling velocity to decrease greatly, and the fine flocs that do not settle carry pollutants such as suspended solids, bacteria and heavy metal ions into subsequent work links, resulting in a sharp increase in load and affecting the water quality.

[0028] Therefore, please refer to Figures 2-11 In order to realize uniform discharge of the flocculant, the decentralized domestic water disinfection and purification device is further provided with a material throwing cylinder 10, a material blocking plate structure 6, a first sliding rail 2 and an adjusting assembly 7.

[0029] In order to realize the dispersion of the flocculant, the throwing cylinder 10 is located above the flocculation cylinder 12, the throwing cylinder 10 is a hollow cylinder structure, and the flocculant in the throwing cylinder 10 is thrown out along the circumference by centrifugal force when the throwing cylinder 10 rotates. The setting of the centrifugal material scattering makes the flocculant thrown out from the center to the periphery, so as to fall into the flocculation cylinder 12 in a dispersed state.

[0030] In order to avoid the problem that the flocculant is accumulated at the edge and the center is empty caused by the centrifugal material scattering of the throwing cylinder 10, a plurality of third connecting rods 101 are fixed on the surface of the throwing cylinder 10 in the radial direction, and the area near the upper end of the blocking plate structure 6 is rotationally arranged on the third connecting rod 101, so that the blocking plate structure 6 can swing. The first sliding rail 2 is located above the blocking plate structure 6, and the lower surface of the first sliding rail 2 is provided with a variable diameter closed curve groove matched with the blocking plate structure 6. When the blocking plate structure 6 rotates with the throwing cylinder 10, it can change the deflection angle along the radial direction of the throwing cylinder 10 under the action of the variable diameter closed curve groove, so as to uniformly disperse the material thrown out by the throwing cylinder 10 again, and avoid the flocculant from being accumulated at the edge of the flocculation cylinder 12 and the center being empty.

[0031] Specifically, the deflection axis of the blocking plate structure 6 is fixed to the connection part of the third connecting rod 101 and the blocking plate structure 6, and the radius change of the variable diameter closed curve groove makes the end of the blocking plate structure 6 close to the first sliding rail 2 continuously close to or away from the axis of the throwing cylinder 10, so that the blocking plate structure 6 continuously changes the deflection angle and closes to or away from the axis of the throwing cylinder 10.

[0032] In order to change the deflection angle of the blocking plate structure 6 at the fixed position, the adjusting assembly 7 is arranged outside the throwing cylinder 10. When the throwing cylinder 10 rotates, the first sliding rail 2 can be driven by the adjusting assembly 7 to rotate asynchronously, so that the position of the first sliding rail 2 changes continuously, and then the deflection angle of the blocking plate structure 6 at the fixed position is changed.

[0033] Please refer to Figure 7 and Figure 8 In order to facilitate discharging, the throwing cylinder 10 is also provided with a storage assembly 4. The storage assembly 4 includes a plurality of discharge cylinders 43 located inside the throwing cylinder 10. The discharge cylinder 43 is a hollow cylinder structure. The upper end of the discharge cylinder 43 is fixedly connected with a storage cylinder 42. The storage cylinder 42 is gap matched with the throwing cylinder 10. The upper surface of the storage cylinder 42 is communicated with a feeding cylinder 41. The flocculant enters the storage cylinder 42 through the feeding cylinder 41, and is then distributed to each discharge cylinder 43 through the storage cylinder 42. The upper end of the discharge cylinder 43 extends through the support frame 1 and is fixedly connected with the support frame 1. The flocculant usually exists in solid state, commonly in the form of powder or particles. The flocculant is stored in the discharge cylinder 43, and the throwing cylinder 10 serves as a protective cylinder to separate the flocculant from the external environment. If the flocculant is directly placed in the throwing cylinder 10, the water in the flocculation tank 32 is easy to splash out and contact with a large amount of flocculant, which causes the discharge hole of the throwing cylinder 10 to be blocked, affecting the discharging work.

[0034] Please refer to Figure 8 , in order to facilitate the storage assembly 4 and the cooperation of the discharge cylinder 10, the vibration assembly 5 and the air cylinder 11 are also provided, the vibration assembly 5 includes an incomplete gear 51 fixedly sleeved outside the feeding cylinder 41 and an incomplete gear ring 52 fixedly sleeved outside the discharge cylinder 43, the first rabbet 53 cooperating with the incomplete gear 51 is fixed on the upper surface of the discharge cylinder 10, the second rabbet 54 cooperating with the incomplete gear ring 52 is fixed on the inner wall of the discharge cylinder 10, the lifting plate 411 is sleeved outside the feeding cylinder 41, the lifting plate 411 is located below the support frame 1, the air cylinder 11 is fixed on the upper surface of the support frame 1, and the piston rod end of the air cylinder 11 is fixedly connected with the lifting plate 411 through the support frame 1.

[0035] The decentralized domestic water refers to a small and modular water mode of independently completing "water taking, treatment, water use and tail water treatment" at a nearby water point without relying on urban centralized water supply and drainage pipe network. The water quality at the water point fluctuates greatly. For example, in the dry season of winter, it is low-turbidity water with few suspended particles and less flocculant dosage. In the flood season of rainy season, it is high-turbidity water, and the flocculant dosage needs to be greatly increased. The flocculant dosage needs to be adjusted manually according to the water quality, and it is highly dependent on the experience of professional personnel. However, due to the decentralized characteristics, most of the workers are non-professionals, and they lack professional control ability. Therefore, it is difficult to adapt the flocculant dosage to the scene. The following will specifically introduce two discharge modes of the storage assembly 4 to adapt to the difference in flocculant dosage between the dry season of winter and the flood season of rainy season.

[0036] As Figure 13 , hereinafter, the (A) state in Figure 13 and the (B) state in Figure 13 are described as two working modes of the vibration assembly 5: The discharge mode in the dry season of winter: the rotation of the discharge cylinder 10 drives the rotation of the first rabbet 53. At this time, the rotation of the first rabbet 53 will intermittently knock the teeth on the incomplete gear 51 to realize the vibration of the discharge cylinder 43, as shown in Figure 13 (A) state, because the source of the vibration position is in the storage cylinder 42 area, so the discharge amount is limited, which is suitable for low-turbidity water in winter.

[0037] The discharge mode in the flood season of rainy season: the piston rod end of the air cylinder 11 pushes the lifting plate 411 to descend, and then the storage assembly 4 is lowered to separate the first rabbet 53 from the incomplete gear 51, while the second rabbet 54 approaches the incomplete gear ring 52 until they are consistent in height. The rotation of the discharge cylinder 10 drives the rotation of the second rabbet 54 to start cooperating with the incomplete gear ring 52 to make the discharge cylinder 43 vibrate and discharge, as shown in Figure 13 (B) state, because the source of the vibration position is in the discharge cylinder 43 area, the discharge amount is greatly improved, which is suitable for high-turbidity water in the rainy season.

[0038] Further, by controlling the rotation speed of the throwing cylinder 10, the knocking frequency of the first and second rakes 53 and 54 can be adjusted, thereby controlling the vibration intensity of the discharging cylinder 43 and adjusting the discharging amount.

[0039] Please refer to Figure 9 , Figure 10 and Figure 12 , in order to realize that the blocking plate structure 6 can change the deflection angle along the radial direction of the throwing cylinder 10 under the action of the variable-diameter closed curve groove of the first sliding rail 2, the blocking plate structure 6 is provided with a blocking plate 61, a sliding block 64 and a telescopic rod 63.

[0040] The upper end of the blocking plate 61 is fixed with a mounting plate 62, the mounting plate 62 is provided with a mounting groove 67, the third connecting rod 101 passes through the mounting groove 67 and is rotationally connected thereto by a pin shaft; so that the blocking plate 61 can be deflected at an angle.

[0041] The sliding block 64 is provided at one end of the telescopic rod 63 away from the anti-coming-off block 65, and the sliding block 64 is in a spherical structure, so that during the process of deflection of the blocking plate 61, the sliding block 64 can be adaptively deflected at an angle in the variable-diameter closed curve groove of the first sliding rail 2, and will not be stuck.

[0042] The telescopic rod 63 is fixed with an anti-coming-off block 65 at one end extending into the inside of the mounting plate 62, and the inside of the mounting plate 62 is provided with a slide 66 cooperating with the anti-coming-off block 65, during the process of deflection of the blocking plate 61, the telescopic rod 63 can be telescopic to adapt to the requirement of radius change caused by the angle deflection of the blocking plate structure 6, and the anti-coming-off block 65 moves in the slide 66 to stabilize the connection between the telescopic rod 63 and the mounting plate 62, so that the sliding block 64 can always slide in the variable-diameter closed curve groove of the first sliding rail 2.

[0043] Please refer to Figure 11 , in order to change the deflection angle of the blocking plate 61 at the fixed position, the adjusting assembly 7 is provided with a rotating cylinder 71 and a fixed ring 74. The rotating cylinder 71 is provided in the middle of the first sliding rail 2, the rotating cylinder 71 is rotationally connected with the discharging cylinder 43 through a bearing, the rotating cylinder 71 is rotationally connected with a fixed plate 711 near the upper end region outside, the fixed plate 711 is installed on the support frame 1 through bolts to support the rotation of the rotating cylinder 71, a plurality of first connecting rods 712 are uniformly provided on the outside of the rotating cylinder 71 near the lower end region, and the other ends of the first connecting rods 712 are fixedly connected with the first sliding rail 2; the fixed ring 74 is provided outside the throwing cylinder 10, one end of the third connecting rod 101 is fixedly connected with the inner arc surface of the fixed ring 74, the outer arc surface of the fixed ring 74 is provided with a plurality of teeth 75 near the upper end region in the circumferential direction, and the outside of the teeth 75 is provided with a first gear 73 meshing with the teeth 75; a driven pulley 76 is fixedly sleeved outside the rotating cylinder 71, a driving pulley 77 is sleeved outside the central shaft of the first gear 73, and the central shaft of the first gear 73 is rotationally installed on the support frame 1; and the outer surfaces of the driven pulley 76 and the driving pulley 77 are transmissionally connected with a belt 72.

[0044] Specifically, the rotating of the throwing cylinder 10 drives the fixed ring 74 to rotate synchronously through the third connecting rod 101. When the fixed ring 74 rotates 360°, the external gear teeth 75 mesh with the first gear 73 to drive the first gear 73 to rotate a certain angle, and then the rotating of the rotating drum 71 drives the first sliding rail 2 to rotate the same angle through the first connecting rod 712 under the transmission of the driving pulley 77, the driven pulley 76 and the belt 72, so as to realize the position change of the first sliding rail 2, i.e. the position change of the variable-diameter closed curve groove, so that the deflection angle of the baffle plate 61 at the fixed position changes compared with the previous circle.

[0045] Further, in order to avoid the sliding of the sliding block 64 in the variable-diameter closed curve groove driving the first sliding rail 2 to rotate synchronously when the baffle plate structure 6 rotates with the throwing cylinder 10, here the limiting assembly 8 is also provided, which includes the protrusion 82 provided on the lower surface of the first gear 73, the second sliding rail 81 provided on the outer portion of the fixed ring 74 close to the lower end area, and the plurality of second connecting rods 84 connected between the second sliding rail 81 and the fixed ring 74, and the plurality of sliding grooves 83 provided on the lower surface of the protrusion 82 and matched with the second sliding rail 81.

[0046] For example, as Figure 14 the rotating of the throwing cylinder 10 drives the first sliding rail 2 to rotate 180°, the position change of the first sliding rail 2 at the fixed position (a), the state change of the baffle plate structure 6 and the position change of the two sliding grooves 83 are described as follows: For example, as Figure 14In the state of (A) in the figure, the radius of the variable radius closed curve groove of the first slide rail 2 at the fixed position (a) is the maximum, and the lower end of the baffle plate 61 at the fixed position (a) is close to the axis of the throwing cylinder 10 to guide the flocculating agent thrown out of the throwing cylinder 10 to the middle of the flocculating cylinder 12. When the throwing cylinder 10 rotates, the baffle plate structure 6 rotates with the throwing cylinder 10 through the third connecting rod 101, the sliding block 64 slides in the variable radius closed curve groove, the deflection axis of the baffle plate structure 6 is fixed at the connection part of the third connecting rod 101 and the mounting groove 67, and the change of the radius of the variable radius closed curve groove makes the sliding block 64 of the baffle plate structure 6 continuously close to or away from the axis of the throwing cylinder 10, so that the baffle plate 61 continuously deflects at an angle, close to or away from the axis of the throwing cylinder 10, uniformly dispersing the material thrown out of the throwing cylinder 10 again, avoiding the flocculating agent from accumulating at the edge of the flocculating cylinder 12 and leaving a vacancy in the center, and avoiding the sliding block 64 from driving the first slide rail 2 to rotate synchronously in the variable radius closed curve groove when the second slide rail 81 is clamped into one sliding groove 83 of the protrusion 82.
