[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0033] Please refer to Figures 1-7 , in the embodiments of the utility model, a high coagulation effect sedimentation device for water purification, including support body 1, flocculation tank 2 is established at the top of support body 1, the bottom of flocculation tank 2 is set as inverted trapezoidal, and honeycomb pipe 5 is installed in the inside of flocculation tank 2, overflow shell 6 is arranged at the inside of the upper end of flocculation tank 2, the upper end of both sides of overflow shell 6 is set as sawtooth, and one end is connected and fixed with partition 7 through overflow pipe 8, the inside wall of side tank 9 is partition 7.
[0034] The bottom of side tank 9 is connected with straight pipe 10, the water inlet end of straight pipe 10 is connected with waste water pump 11, and the water outlet end is connected with centrifugal separator 12 through pipeline, the top of centrifugal separator 12 is connected with storage tank 16 through water delivery pipe 14.
[0035] Through the above technical scheme, the pre-treated waste water is discharged into flocculation tank 2 to carry out sedimentation and flocculation, the waste water after adding flocculant gathers with particles to form larger floc. At this time, the probability of mutual collision and aggregation between particles increases, and the sedimentation process is no longer the independent behavior of single particle, but multiple flocs are intertwined and collided to sink together. In this process, the sedimentation speed gradually increases because the particle size of floc is continuously increasing.
[0036] The presence of the honeycomb tube 5 greatly increases the effective sedimentation area of the sedimentation tank. In the case of a constant amount of water being treated, the larger the sedimentation area, the more chances the suspended particles in the water have to come into contact with the inclined tube, thereby improving the sedimentation effect.
[0037] Because the honeycomb tube 5 provides more sedimentation surface, the particles can settle faster to the bottom of the honeycomb tube 5, reducing the settling distance and time of the particles. This is very important for wastewater treatment systems that have a large amount of water to be treated and require a certain amount of time for treatment, and can improve the efficiency of the entire treatment process.
[0038] The water quality of the wastewater after flocculation and sedimentation is improved. As the water level continues to rise, the wastewater overflows into the overflow shell 6, then enters the side tank 9 through the overflow pipe 8 on the partition 7, and the wastewater pump 11 draws the wastewater out through the straight pipe 10 and delivers it to the centrifugal separator 12. The wastewater enters along the tangent direction of the top inlet of the centrifugal separator 12, forming a high-speed rotating flow field. Due to the centrifugal force generated by rotation, the solid particles or substances with a higher density in the wastewater are thrown to the wall of the device, and then slide down along the inner wall of the centrifugal separator 12 under the action of gravity and wall friction, finally collecting in the collection hopper at the bottom, while the liquid with a lower density forms an internal vortex and flows out from the center overflow pipe, thereby achieving solid-liquid separation or separation of different density liquids.
[0039] Thus, the separation of solid particles and flocculation groups that are discharged with the wastewater is achieved, thereby improving the water purification effect for subsequent deep treatment processes.
[0040] In this embodiment, the overflow shell 6 is clamped at both ends on the U-shaped hoop 20; the U-shaped hoop 20 is installed on the C-shaped channel steel 21 through a nut; and the C-shaped channel steel 21 is fixed at both ends to the flocculation tank 2 through bolts.
[0041] The C-shaped channel steel 21 facilitates the installation of the U-shaped hoop 20, thereby achieving the hoisting and fixing of the overflow shell 6.
[0042] In this embodiment, the flocculation tank 2 is provided with a backwashing hole 15 on one side of the lower end, and a blowdown pipe is arranged at the middle position of the bottom of the flocculation tank 2, and a butterfly valve is connected in series on the blowdown pipe.
[0043] By adopting the above technical solution, after the butterfly valve is opened, the flocculated sludge can be discharged through the blowdown pipe at the bottom of the flocculation tank 2; and clean water can be introduced into the backwashing hole 15 to flush the flocculation tank 2.
[0044] In this embodiment, the flocculation tank 2 is fixedly installed with a dosing hopper 3 at the top, and a dosing pipe 4 vertically penetrates the inside of the dosing hopper 3. The dosing pipe 4 is located inside the flocculation tank 2 and extends below the honeycomb tube 5.
[0045] The flocculation agent is conveniently added to the wastewater, and the flocculation process is below the honeycomb pipe 5, so that the flocculation particles can be prevented from floating upward, and the precipitation efficiency of the flocculation group is increased.
[0046] In the embodiment, the flocculation tank 2 is further fixed with an inspection platform 18 located on one side of the dosing hopper 3, and a guardrail is arranged on the inspection platform 18.
[0047] By adopting the above technical scheme, the flocculation agent is conveniently added, and the equipment is convenient to maintain and repair.
[0048] In the embodiment, the top of the storage tank 16 is provided with a protective fence in a C-shaped form, and a ladder 19 is arranged at the C-shaped gap, one end of the ladder 19 is fixed with the storage tank 16, and the other end is fixed with the flocculation tank 2.
[0049] In the embodiment, the centrifugal separator 12 is fixedly installed in the mounting bracket 13, and the taper angle of the centrifugal separator 12 is 10-30 degrees.
[0050] By adopting the above technical scheme, a smaller diameter usually generates a larger centrifugal force, which is beneficial to separation, but the processing capacity is relatively small; on the contrary, a larger diameter is opposite. The size of the taper angle affects the sliding speed of the solid particles or oil droplets on the wall, and a suitable taper angle can make the separated substances smoothly discharge; when the taper angle of the centrifugal separator is between 10°-30°, the sliding of the solid particles is more favorable.
[0051] In the embodiment, the storage tank 16 includes a tank body 161, and the tank body 161 is internally provided with a filter 162; the top of the filter 162 is fixedly connected with a sealing cover 163, and a water outlet pipe 164 is fixedly installed on the top of the sealing cover 163; the lower end of the water outlet pipe 164 is connected with the inside of the filter 162, and the top penetrates to the upper side of the tank body 161. The filter 162 is integrally provided in a cylindrical shape, and the outer side is a mesh cylinder, and the inner side is an activated carbon adsorption layer.
[0052] By adopting the above technical scheme, the wastewater entering the tank body 161 gradually penetrates into the inside of the filter 162, so as to realize the re-filtering treatment of the wastewater; as the water level continuously increases, the filtered clean water is discharged from the water outlet pipe 164.
[0053] In the embodiment, the lower end of the tank body 161 is provided with a backwashing pipe 165 penetrating into the inside of the filter 162; and a valve is connected in series on the backwashing pipe 165; and a butterfly valve 166 is connected in series on the top of the water outlet pipe 164.
[0054] Through the above technical scheme, after long time use, a large amount of impurities are adsorbed on the outer net cylinder, after closing the butterfly valve 166, opening the valve on the back flushing pipe 165, and passing clean water, reverse flushing of the filter 162 can be realized, thereby increasing the service life of the filter 162.
[0055] The working principle of the utility model is: the pre-processed wastewater is discharged into the flocculation tank 2 for sedimentation and flocculation, the wastewater after adding flocculant aggregates with particles to form larger flocs. At this time, the probability of mutual collision and aggregation between particles increases, and the sedimentation process is no longer the independent behavior of a single particle, but multiple flocs entangle and collide with each other and sink together. In this process, the sedimentation speed gradually increases because the particle size of the flocs is continuously increasing.
[0056] The presence of the honeycomb pipe 5 greatly increases the effective sedimentation area of the sedimentation tank. Under the condition that the water treatment capacity is unchanged, the larger the sedimentation area, the more opportunities the suspended particles in the water have to contact the inclined pipe, thereby improving the sedimentation effect.
[0057] The water quality of the wastewater after flocculation and sedimentation is improved, and as the water level continuously increases, the wastewater overflows into the overflow shell 6, then enters the side tank 9 through the overflow pipe 8 on the partition plate 7, the wastewater pump 11 draws the wastewater out through the straight pipe 10 and delivers it to the centrifugal separator 12; the wastewater enters along the tangent direction of the top inlet of the centrifugal separator 12 to form a high-speed rotating flow field. Due to the centrifugal force generated by rotation, the solid particles or substances with higher density in the wastewater are thrown to the wall, then slide down along the inner wall of the centrifugal separator 12 under the action of gravity and wall friction, and finally collected in the collection hopper at the bottom, while the liquid with smaller density forms an internal vortex and flows out from the center overflow pipe, thereby realizing solid-liquid separation or separation of different density liquids.
[0058] The wastewater entering the tank body 161 gradually penetrates into the filter 162, thereby realizing re-filtering treatment of the wastewater; as the water level continuously increases, the filtered clean water is discharged from the water outlet pipe 164.
[0059] After long time use, a large amount of impurities are adsorbed on the outer net cylinder, after closing the butterfly valve 166, opening the valve on the back flushing pipe 165, and passing clean water, reverse flushing of the filter 162 can be realized, thereby increasing the service life of the filter 162.
[0060] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
