Description

Technical Field

[0001] This utility model relates to the field of sedimentation machine technology, specifically a low-power pretreatment sedimentation tank cyclone sedimentation machine. Background Technology

[0002] A cyclone sedimentation tank is often used in the pretreatment of sewage. Its principle is to use a propeller to drive the sewage in the tank to rotate. Under the combined action of gravity and centrifugal force, the particles in the sewage and the small impurities on the surface of the sand are separated, so that the particles and sand settle at the bottom, while the lighter impurities in the sewage float at the top, thus achieving the purpose of separation.

[0003] A low-power cyclone sedimentation machine, CN 219942091 U, relates to the field of sedimentation machine technology. It includes a sedimentation tank with a fixing assembly fixedly installed on its lower outer surface. The inner cavity of the sedimentation tank is provided with a screening chamber and a sedimentation chamber. An outlet is opened on one outer surface of the sedimentation tank, and a feed inlet is opened at the upper end of the sedimentation tank. A feed cover is provided on the outer surface of the feed inlet. This invention uses the coordinated operation of a filter cylinder, a discharge pipe, and a blower to filter light pollutants. It ensures that light pollutants are directly discharged through the discharge pipe, reducing the pressure of subsequent separate cleaning. The rotation of the propeller blades agitates the sand inside the sedimentation chamber, achieving the combined effect of centrifugal force, centripetal force, buoyancy, and fluid drag, causing the low-density water to rise and be discharged through the outlet, thus achieving sand deposition and a more efficient sedimentation process.

[0004] The aforementioned device can clean the sand before sedimentation. During cleaning, the sand clumps are broken up by controlling the rotation of the dispersing rod, and the sand can also be separated from light pollutants. However, when breaking up relatively hard clumps of sand, it will damage the filter tank, resulting in a reduced service life. Therefore, a low-power pretreatment sedimentation tank cyclone sedimentation machine is proposed. Utility Model Content

[0018] Beneficial effects

[0019] Compared with the prior art, this utility model provides a low-power pretreatment sedimentation tank cyclone grit chamber, which has the following beneficial effects:

[0020] 1. The cleaning mechanism can clean the sand before it settles, breaking up clumps and separating the sand from its internal light contaminants, making it easier for the sand to settle. During sand cleaning, the connecting column rotates, and the centrifugal force causes the two dispersing plates to open outwards. After the two dispersing plates open outwards, their outer surfaces come into contact with the top of the filter screen, resulting in a more thorough cleaning. Furthermore, the dispersing plates can be adjusted according to the vibration frequency of the filter screen, effectively preventing damage to the filter screen. After the sand is broken up, controlling the vibration of the filter screen increases the filtration efficiency and effectively prevents the filter screen from clogging. After cleaning, the light contaminants on the top of the filter screen can be removed by manually pulling open the baffle. Moreover, the sand cleaning process is powered by only one power source, resulting in lower energy consumption during processing.

[0021] 2. By setting up a sedimentation mechanism, sand and water can be separated. During the sedimentation process, the propeller blades rotate, which agitates the sand. Under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the drain pipe, thus achieving sand deposition. Furthermore, when it is necessary to discharge the deposited sand, clogging can be avoided by controlling the rotation of two anti-clogging rods. Attached Figure Description

[0034] A connecting column 23 is rotatably mounted on the inner left end face of the sedimentation tank 1 via a bearing seat. Two fixing frames 24 are fixedly mounted on the front and rear ends of the connecting column 23. Two connecting plates 27 are slidably mounted on the inner sides of the two fixing frames 24. The outer sides of the two connecting plates 27 are fixedly connected to the inner sides of two dispersing plates 25. The outer sides of the two dispersing plates 25 slidably extend through the inner sides of the two fixing frames 24 to the outer sides of the two fixing frames 24. Two sets of dispersing rods are fixedly mounted on the surfaces of the two dispersing plates 25. Two elastic elements 219 are fixedly mounted on the front and rear ends of the connecting column 23. The outer sides of the two elastic elements 219 are fixedly connected to the inner sides of the two connecting plates 25. The inner side of the connecting plate 27 is fixedly connected. The rear end face of the filter screen 211 is hinged to the inner rear end face of the sedimentation box 1. The inner front end face of the sedimentation box 1 is fixedly provided with a mounting plate 29. Two springs 210 are fixedly provided on the top surface of the mounting plate 29. The top surfaces of the two springs 210 are fixedly connected to the bottom surface of the filter screen 211. The filter screen 211 is inclined and located below the two dispersing plates 25. A fixing frame 28 is fixedly provided on the back of the sedimentation box 1. The inner rear end face of the fixing frame 28 is fixedly connected to the back of the first motor 214. The front of the output end of the first motor 214 extends through the back of the sedimentation box 1 and into the interior of the sedimentation box 1. The output end is fixedly connected to the back of the connecting column 23. A rotating rod 218 is rotatably mounted on the inner rear end face of the fixing frame 28 via a bearing seat 2. The rotating rod 218 extends through the back of the settling box 1 and into the interior of the settling box 1. The rotating rod 218 is fixedly connected to the back of the cam 212. The cam 212 is located below the filter screen 211. A discharge frame 21 is fixedly mounted through the front of the settling box 1 and extends into the interior of the settling box 1. A baffle 22 is slidably mounted through the right side of the discharge frame 21 and extends to the left side of the discharge frame 21. An installation rod 216 is rotatably mounted on the inner rear end face of the fixing frame 28 via a bearing seat 3. A fixing sleeve is mounted on the surface of the installation rod 216. A second gear 215 is provided, and a first gear 213 is fixedly sleeved on the output end surface of the first motor 214. The tooth surface of the first gear 213 meshes with the tooth surface of the second gear 215.

[0035] In this embodiment, the cleaning mechanism 2 can clean the sand before it settles, breaking up clumps of sand and separating it from its internal lightweight contaminants, making it easier for the sand to settle. During sand cleaning, the connecting column 23 rotates, and centrifugal force causes the two dispersing plates 25 to open outwards. After opening, the outer surfaces of the two dispersing plates 25 contact the top of the filter screen 211, resulting in more thorough sand cleaning. Furthermore, the dispersing plates 25 can adjust to the vibration frequency of the filter screen 211, effectively preventing damage to the filter screen 211. After the sand is broken up, controlling the vibration of the filter screen 211 increases filtration efficiency and effectively prevents clogging. After cleaning, the baffle 22 can be manually pulled open to remove the lightweight contaminants from the top of the filter screen 211. The sand cleaning process is powered by only one power source, resulting in lower energy consumption.

[0036] Example 2

[0037] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the sedimentation mechanism 4 includes a second motor 46. The top surface of the output end of the second motor 46 extends through the bottom surface of the sedimentation box 1 and into the interior of the sedimentation box 1. A connecting rod 44 is fixedly installed on the top surface of the output end of the second motor 46. A propeller blade 43 is fixedly installed on the surface of the connecting rod 44. Two sand discharge frames 41 are fixedly installed through the surface of the sedimentation box 1 and extend into the interior of the sedimentation box 1. Two blocking blocks 42 are respectively installed on the inner side of the two sand discharge frames 41. Two anti-blocking rods 45 are fixedly installed on the surface of the connecting rod 44. The two anti-blocking rods 45 are located below the propeller blade 43. A drain pipe 47 is fixedly installed through the surface of the sedimentation box 1 and extends into the interior of the sedimentation box 1. A valve is installed inside the drain pipe 47.

[0038] In this embodiment, the sand and water can be separated by setting the sedimentation mechanism 4. During the sedimentation process, the propeller blade 43 rotates, which can agitate the sand. Under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the drain pipe 47, thus achieving sand deposition. When it is necessary to discharge the deposited sand, the two anti-blocking rods 45 can be rotated to avoid blockage.

[0039] In use, firstly, the user pours the sand to be treated into the sedimentation tank 1 through the feed chute. The sand will gather above the filter screen 211. Then, the first motor 214 is turned on. After the first motor 214 is turned on, the connecting column 23 rotates. During the rotation of the connecting column 23, the centrifugal force causes the two dispersing plates 25 to expand outward. After the two dispersing plates 25 expand outward, they can agitate the sand above the filter screen 211. During the agitation process, the clumps of sand can be broken up, and the sand can be separated from light pollutants. When the output end of the first motor 214 rotates, the mounting rod 216 can be rotated synchronously through the first gear 213 and the second gear 215. And because the first gear 213 and the second gear 215 rotate synchronously, the mounting rod 216 rotates synchronously. The two gears 215 have different diameters, which reduces the rotation speed of the mounting rod 216. The pulley 217 causes the rotating rod 218 to rotate when the mounting rod 216 rotates. The rotation of the rotating rod 218 causes the cam 212 to rotate. When the cam 212 rotates, it strikes the bottom of the filter screen 211. During the striking process, the two springs 210 cause the filter screen 211 to vibrate. The filter screen 211 can filter the sand after it is broken up. Light pollutants in the sand will remain on the top of the filter screen 211. After the sand on the top of the filter screen 211 is filtered, the baffle 22 is pulled open. After the baffle 22 is pulled open, the light pollutants on the top of the filter screen 211 can be removed.

[0040] After the sand falls to the bottom of the sedimentation tank 1, the second motor 46 is activated. When the output end of the second motor 46 rotates, the connecting rod 44 rotates, and the propeller blade 43 rotates. When the propeller blade 43 rotates, it can agitate the sand. Under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the drain pipe 47, thus achieving sand deposition. After the sand deposition is completed, the two block blocks 42 are pulled open, and the second motor 46 is activated. After activation, the two anti-blocking rods 45 rotate. When the two anti-blocking rods 45 rotate, they can prevent the two sand discharge frames 41 from being blocked when the sand is discharged.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
