Description

TECHNICAL FIELD

[0002] The high density sedimentation tank is a kind of compact, efficient, flexible new water treatment process.The high density sedimentation tank is mainly composed of three parts, which are quick mixing tank, flocculation reaction tank and sedimentation separation tank.Water enters the quick mixing tank, and flocculant is added simultaneously, is stirred quickly, to achieve rapid flocculation, and avoid alum flower deposition.The effluent of quick mixing tank is discharged into the flocculation reaction tank, and coagulant aid is added in the lower part of the reaction tank by dosing device, to generate large alum flower, and the stirring rate in the reaction tank is controlled (the stirring rate is lower than that of quick mixing tank), to prevent alum flower from being broken and forming sediment in the reaction zone.Wastewater carrying alum flower enters the sedimentation separation tank, and most of the alum flower is precipitated and concentrated here, and the mud scraper at the bottom of the sedimentation separation tank is continuously scraped to promote the concentration of the sediment sludge, and part of the sludge is returned to the flocculation reaction tank through the sludge return pipe to maintain the required sludge concentration in the flocculation reaction tank, promote the growth of alum flower in the flocculation process and improve the density of alum flower, and the remaining sludge is discharged for further dewatering treatment.

[0003] The upper part of the sedimentation separation tank is provided with an inclined plate sedimentation device for removing residual fine alum flower, and the final output is qualified clean water.The inclined plate sedimentation device is a water treatment equipment based on the principle of gravity sedimentation, which significantly increases the sedimentation area in unit volume by installing inclined parallel plates in the sedimentation tank, thereby improving the sedimentation efficiency, and the setting of the inclined plate makes the water entering the sedimentation tank form laminar flow on the plate surface, which helps solid particles to separate from water and accelerates the sedimentation process.Because the solid particles are between multiple inclined plates, the difficulty of cleaning the solid particles between the inclined plates is relatively large, and the solid particles are accumulated in the inclined plate for a long time, which easily affects the water flow velocity between the inclined plates, thereby reducing the water treatment efficiency.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Refer to the instruction manual Figure 1 The utility model provides an inclined plate sedimentation device for a high-density sedimentation tank, including an inclined plate sedimentation device body 200 , which is installed in a high-density sedimentation tank 100 .

[0035] like Figure 2-7 As shown, the inclined plate sedimentation device body 200 includes multiple groups of inclined plate assemblies 1 arranged obliquely, and the inclined plate assembly 1 includes two inclined plate mounting frames 11 distributed upper and lower, and an inclined plate 12 is installed between the two inclined plate mounting frames 11, and the two ends of the inclined plate 12 are respectively slidably engaged in the inclined plate mounting frames 11 at both ends of the inclined plate 12, so as to facilitate the disassembly and assembly of the inclined plate 12 and the inclined plate mounting frames 11, and the adjacent inclined plate mounting frames 11 are fixedly connected by a connecting rod 2, and two of the inclined plate mounting frames 11 in the upper inclined plate mounting frame 11 are fixed with two hangers 3, and the hangers 3 are hung on the front and rear side walls of the high-density sedimentation tank 100 to facilitate the installation of the inclined plate sedimentation device body 200.

[0036] A cleaning assembly 13 is provided on one side of each inclined plate 12. The cleaning assembly 13 is driven by a driving assembly 14 provided on one side of the inclined plate 12 and is used to clean solid particles between the inclined plates 12. The cleaning assembly 13 includes a transverse plate 131 and a first cleaning cotton 132 and a second cleaning cotton 133 respectively fixed on both sides of the transverse plate 131. The first cleaning cotton 132 and the second cleaning cotton 133 are both made of sponge. The first cleaning cotton 132 is in contact with the surface of the inclined plate 12 on one side of the transverse plate 131, and the second cleaning cotton 133 is in contact with the surface of the inclined plate 12 on the other side of the transverse plate 131.

[0037] The driving assembly 14 includes a shell 141 provided on one side of the inclined plate 12, and the shell 141 is fixed to one side of the two inclined plate mounting frames 11. The shell 141 contacts the internal front wall of the high-density sedimentation tank 100. Drive wheels 142 are provided at both ends of the shell 141. A rotating shaft 143 is fixed in the drive wheel 142. The rotating shaft 143 is rotatably connected to the shell 141. A drive belt 144 is sleeved on the two drive wheels 142. The drive wheel 142 can select a pulley or sprocket structure, and the drive belt 144 can select a corresponding belt or chain structure. A slide groove 145 is provided on the side of the shell 141 close to the cleaning assembly 13.

[0038] A slider 134 is fixed to one end of the horizontal plate 131 close to the driving component 14. The slider 134 passes through the slide groove 145 and is fixedly connected to the driving belt 144. The slider 134 can slide along the slide groove 145. The driving wheel 142 drives the driving belt 144 to rotate and drives the cleaning component 13 to move along the surface of the inclined plate 12 to clean between the inclined plates 12.

[0039] It is worth noting that in order to prevent solid particles in the water from entering the housing 141 through the chute 145 and hindering the rotation of the rotating shaft 143, the chute 145 can be sealed in practice, but it is necessary not to hinder the movement of the slider 134 along the chute 145. This embodiment uses an example of a sealing method, and other sealing structures are within the scope of protection of this utility model:

[0040] Two contacting rubber sealing strips can be pasted in the slide groove 145, and the slider 134 is located between the contact surfaces of the two sealing strips. When the slider 134 slides in the slide groove 145, it can move between the two sealing strips. At this time, other areas in the slide groove 145 are sealed by the sealing strips that contact each other. Although the sealing strip around the slider 134 cannot guarantee that the gap between the sealing strip and the slider 134 is completely sealed, since the rubber sealing strip can wrap and fit the slider 134 well, the gap between the sealing strip and the slider 134 can be small enough to prevent solid particles from entering the slide groove 145.

[0041] Next, in order to facilitate the movement of the transverse plate 131 , balls 135 are fixed at both ends of the transverse plate 131 . The balls 135 close to the shell 141 are in contact with the shell 141 , and the balls 135 away from the shell 141 are in contact with the inner rear wall of the high-density sedimentation tank 100 .

[0042] The front end of the high-density sedimentation tank 100 is provided with a driving roller 4 with the same number as the rotating shaft 143, and the driving roller 4 corresponds to the rotating shaft 143 one by one. The driving roller 4 includes a hollow roller body 41 provided at the front end of the high-density sedimentation tank 100, and the hollow roller body 41 extends into the front end of the high-density sedimentation tank 100. The hollow roller body 41 is rotatably connected to the high-density sedimentation tank 100 through a sealed bearing, which facilitates the rotation of the hollow roller body 41 and seals the hollow roller body 41 between the high-density sedimentation tank 100. A clamping rod 42 is provided in the hollow roller body 41, and the rear end of the clamping rod 42 passes through the hollow roller body 41 and extends into the high-density sedimentation tank 100, and the rear end top and rear end bottom of the clamping rod 42 are processed into inclined surfaces. The front end of the clamping rod 42 is connected to the inner wall of the hollow roller body 41 by a spring 43. A sealing design is required between the clamping rod 42 and the hollow roller body 41. For example, a sealing gasket is installed between the hollow roller body 41 and the clamping rod 42 to prevent solid particles in the water from entering the hollow roller body 41.

[0043] A card slot 146 that matches the rear end of the card rod 42 is provided at the front end of the rotating shaft 143. The inclined plate sedimentation device body 200 is placed into the high-density sedimentation tank 100 from top to bottom. When the shell 141 contacts the inclined surface of the card rod 42, the shell 141 continues to move downward to drive the card rod 42 to move into the hollow roller body 41, thereby compressing the spring 43. When the card slots 146 on the multiple rotating shafts 143 correspond one-to-one with the card rods 42 of the multiple driving rollers 4, the rear end of the card rod 42 is snapped into the card slot 146 under the elastic force of the spring 43, thereby realizing the connection between the driving roller 4 and the rotating shaft 143. Figure 8-9 As shown, the hanger 3 is then hung on the front and rear side walls of the high-density sedimentation tank 100 to achieve the installation of the inclined plate sedimentation device body 200 and the high-density sedimentation tank 100. The arrangement of multiple inclined plates 12 on the high-density sedimentation tank 100 enables the water in the high-density sedimentation tank 100 to form a laminar flow on the plate surface, which helps to separate solid particles from water.

[0044] The plurality of hollow rollers 41 are connected to each other through a belt pulley transmission structure or a chain sprocket transmission structure, and the plurality of hollow rollers 41 are driven to rotate by external equipment such as a motor, thereby driving the plurality of rotating shafts 143 to rotate, driving the driving wheel 142 to rotate, and the driving belt 144 is driven to rotate by the driving wheel 142, thereby driving the cross plate 131 to move through the slider 134, and the movement of the cross plate 131 drives the first cleaning cotton 132 and the second cleaning cotton 133 to move downward along the surface of the inclined plate 12, thereby cleaning the solid particles on the surface of the inclined plate 12, which not only improves the solid particle sedimentation efficiency, but also realizes the cleaning of the solid particles between the inclined plates 12, avoids the accumulation of solid particles between the inclined plates 12 affecting the water flow rate, and ensures the water treatment efficiency;

[0045] At the same time, since the sponge material of the first cleaning cotton 132 and the second cleaning cotton 133 has a filtering effect, when the water flows upward between the inclined plates 12, the first cleaning cotton 132 and the second cleaning cotton 133 can block the solid particles in the water, thereby effectively improving the water treatment effect.
