Abstract
Description
Technical Field
[0001] This utility model belongs to the field of settling tanks, and more specifically, it is a concentration settling tank. Background Technology
[0002] Settling tank liquid sampling refers to the process of inputting a liquid containing various complex impurities into the settling tank, where the liquid to be sampled is separated from the impurities through gravity settling, chemical demulsification, electric field dehydration, and water washing. The separated impurities settle to the bottom of the settling tank, while the liquid sample to be obtained floats to the top of the settling tank and is finally sampled through the sample outlet.
[0003] During the use of settling tanks, flocculants are generally added to accelerate the sedimentation of impurities in the settling tank. However, existing technology makes it difficult to control the amount of flocculant used. Adding too much flocculant at once will cause the flocculant to clump together, making it difficult to mix with the liquid in the settling tank and thus failing to achieve an effective flocculation effect. In addition, most flocculants are in powder form and are relatively light, so the added flocculant tends to float on the surface of the liquid and is difficult to quickly penetrate into the interior of the liquid to flocculate impurities. Utility Model Content
[0004] To address these issues, this invention provides a concentration settling tank to solve the problems of existing technologies where it is difficult to control the amount of flocculant used, leading to agglomeration, and the difficulty of quickly dispersing and taking effect of powdered flocculants that tend to float on the liquid surface.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a concentration sedimentation tank, including a tank body, a support foot fixedly connected to the bottom of the tank body, a feed valve provided at the top of the tank body, a discharge valve provided at the bottom of the tank body, a motor fixedly connected to the top of the tank body, the output end of the motor extending into the interior of the tank body and fixedly connected to a rotating shaft, a stirring rod fixedly connected to the outer wall of the rotating shaft, a sleeve fixedly connected to the top of the inner wall of the tank body, the rotating shaft rotatably connected to the sleeve, a cavity being opened inside the sleeve, and a metering component being provided at the top of the tank body.
[0006] Preferably, the metering component includes a feed pipe, which is fixedly installed on the top of the tank. A feed hopper is fixedly connected to the top of the feed pipe, and the bottom of the feed pipe extends into the cavity. Two discharge ports are symmetrically opened on the inner wall of the sleeve. A discharge chamber is opened inside the rotating shaft. Two feed ports are symmetrically opened on the outer wall of the rotating shaft. The feed ports communicate with the discharge chamber and are located inside the cavity. Several discharge ports are equidistantly opened on the outer wall of the rotating shaft below the feed ports and communicate with the discharge chamber.
[0007] Preferably, a guide plate is fixedly connected to the outer wall of the rotating shaft and below the discharge port, and the top of the guide plate is set as a continuous slope.
[0008] Preferably, a slider is slidably connected to the outer wall of the rotating shaft and below the guide plate. A limit groove is formed on the inner wall of the slider. A limit strip is fixedly connected to the outer wall of the rotating shaft. The limit strip fits into the inner wall of the limit groove. A plurality of floats are fixedly connected at equal intervals to the outer wall of the slider. A lower pressure plate is fixedly connected to the bottom of the float. The bottom of the lower pressure plate is set as a symmetrical arc surface. A counterweight is fixedly connected to the bottom of the lower pressure plate.
[0009] Preferably, the top of the float is configured as a symmetrical slope.
[0010] Preferably, the tank has an internal water collection trough, an external water inlet on the outer wall of the tank that communicates with the water collection trough, and an external water outlet on the outer wall of the tank below the water inlet that communicates with the water collection trough.
[0011] Preferably, a fixing ring is fixedly connected to the outer wall of the tank, and a plurality of sliding shafts are equidistantly slidably connected to the inner wall of the fixing ring. A limit block is fixedly connected to the top of the sliding shaft, and a retaining ring is fixedly connected to the bottom of the sliding shaft. The retaining ring fits against the outer wall of the water outlet. A spring is sleeved on the outer wall of the sliding shaft. The bottom of the spring is fixedly connected to the retaining ring, and the top of the spring is fixedly connected to the fixing ring.
[0012] Preferably, the outer wall of the tank is provided with an observation window, and the inner wall of the observation window is fixedly connected with a transparent cover plate.
[0013] The advantages of this utility model's technical solution, which differs from existing technologies, are as follows:
[0014] 1. The concentration settling tank of this utility model controls the rotation of the shaft to intermittently align the inlet and outlet, thereby allowing the flocculant in the cavity to be intermittently and quantitatively added into the liquid inside the tank. This avoids the flocculant from agglomerating in the liquid due to excessive flocculant addition at one time. The flocculant discharged from the outlet falls onto the guide plate, and is further dispersed by the inclined surface at the top of the guide plate, thus allowing the flocculant to fall into the liquid more evenly.
[0015] 2. The concentration settling tank of this utility model, through the setting of a float plate, makes the lower pressure plate float on the liquid surface. Through the setting of a limiting strip and a limiting groove, the float plate can be used for different water depths. Through the setting of a counterweight, a part of the lower pressure plate is placed below the liquid surface. When the rotating shaft rotates, it drives the float plate to rotate, causing the lower pressure plate to rotate. The arc-shaped surface of the outer wall of the lower pressure plate forms a downward pressure on the liquid, preventing the added flocculant from floating on the liquid surface, thereby accelerating the fusion of flocculant and liquid.

[0033] like Figures 1 to 6 As shown, this utility model provides a technical solution: a concentration sedimentation tank, including a tank body 1. Support legs 2 are fixedly connected to the bottom of the tank body 1. A feed valve 3 is provided at the top of the tank body 1, and a discharge valve 4 is provided at the bottom of the tank body 1. A motor 5 is fixedly connected to the top of the tank body 1. The output end of the motor 5 extends into the interior of the tank body 1 and is fixedly connected to a rotating shaft 6. A stirring rod 7 is fixedly connected to the outer wall of the rotating shaft 6. A sleeve 8 is fixedly connected to the top of the inner wall of the tank body 1. The rotating shaft 6 is rotatably connected to the sleeve 8. A cavity 9 is provided inside the sleeve 8. A metering component is provided at the top of the tank body 1. The component includes a feed pipe 10, which is fixedly installed on the top of the tank 1. A feed hopper 11 is fixedly connected to the top of the feed pipe 10. The bottom of the feed pipe 10 extends into the cavity 9. Two discharge ports 12 are symmetrically opened on the inner wall of the sleeve 8. A discharge chamber 13 is opened inside the rotating shaft 6. Two feed ports 14 are symmetrically opened on the outer wall of the rotating shaft 6. The feed ports 14 communicate with the discharge chamber 13. The feed ports 14 are located inside the cavity 9. Several discharge ports 15 are equidistantly opened on the outer wall of the rotating shaft 6 below the feed ports 14. The discharge ports 15 communicate with the discharge chamber 13.
[0034] Through the above technical solution, the liquid to be settled is put into the tank 1 through the feed valve 3, and the flocculant is put into the feed hopper 11. The flocculant entering the feed hopper 11 enters the cavity 9 through the feed pipe 10. The motor 5 is started, which drives the rotating shaft 6 to rotate. The feed port 14 rotates. When the feed port 14 rotates to the position that is close to the discharge port 12, the flocculant in the cavity 9 enters the discharge chamber 13 through the discharge port 12 and the feed port 14. When the feed port 14 rotates to the position that is far away from the discharge port 12, the discharge port 12 is blocked by the outer wall of the rotating shaft 6 to prevent the discharge port 12 from continuously discharging. The flocculant entering the discharge chamber 13 is discharged from several discharge ports 15. This allows the flocculant to be added intermittently and quantitatively, avoiding the flocculant from agglomerating in the liquid due to the addition of too much flocculant at one time.
[0035] Specifically, a guide plate 16 is fixedly connected to the outer wall of the rotating shaft 6 and below the discharge port 15, and the top of the guide plate 16 is set as a continuous slope.
[0036] Through the above technical solution, the flocculant discharged from the discharge port 15 falls onto the guide plate 16. Guided by the inclined surface at the top of the guide plate 16, the flocculant is more dispersed, thereby making the flocculant fall into the liquid more evenly. While the rotating shaft 6 rotates, it drives the stirring rod 7 to rotate, stirring the flocculant in the liquid and accelerating the flocculation of impurities in the liquid.
[0037] Specifically, a slider 17 is slidably connected to the outer wall of the rotating shaft 6 and below the guide plate 16. A limit groove 19 is formed on the inner wall of the slider 17. A limit strip 18 is fixedly connected to the outer wall of the rotating shaft 6. The limit strip 18 fits against the inner wall of the limit groove 19. Several floats 20 are fixedly connected at equal intervals to the outer wall of the slider 17. A lower pressure plate 21 is fixedly connected to the bottom of the float 20. The bottom of the lower pressure plate 21 is set as a symmetrical arc surface. A counterweight block 22 is fixedly connected to the bottom of the lower pressure plate 21. The top of the float 20 is set as a symmetrical inclined surface.
[0038] Through the above technical solution, the float plate 20 is set so that the pressure plate 21 floats on the liquid surface. The limit strip 18 and the limit slot 19 are set so that the float plate 20 can be used in different water depths. The counterweight block 22 is set so that part of the pressure plate 21 is below the liquid surface. By setting the top of the float plate 20 as an inclined surface, the flocculant is prevented from accumulating on the float plate 20. When the rotating shaft 6 rotates, it drives the float plate 20 to rotate, which causes the pressure plate 21 to rotate. The arc-shaped surface of the outer wall of the pressure plate 21 forms downward pressure on the liquid, preventing the flocculant from floating on the liquid surface, thereby accelerating the fusion of flocculant and liquid.
[0039] Specifically, the tank body 1 has a water collection tank 23 inside, and a water inlet 24 on the outer wall of the tank body 1, which communicates with the water collection tank 23. A water outlet 25 is located on the outer wall of the tank body 1 below the water inlet 24, and the water outlet 25 communicates with the water collection tank 23. A fixing ring 26 is fixedly connected to the outer wall of the tank body 1. Several sliding shafts 27 are equidistantly slidably connected to the inner wall of the fixing ring 26. A limit block 28 is fixedly connected to the top of the sliding shaft 27, and a retaining ring 30 is fixedly connected to the bottom of the sliding shaft 27. The retaining ring 30 fits against the outer wall of the water outlet 25. A spring 29 is sleeved on the outer wall of the sliding shaft 27. The bottom of the spring 29 is fixedly connected to the retaining ring 30, and the top of the spring 29 is fixedly connected to the fixing ring 26.
[0040] Through the above technical solution, the spring 29, in conjunction with the retaining ring 30, keeps the retaining ring 30 in contact with the outlet 25, sealing the bottom of the water collection tank 23. Cold and warm water can be filled into the water collection tank 23 through the inlet 24, which facilitates the temperature regulation of the tank 1. It is suitable for the settling of temperature-sensitive liquids. When it is necessary to replace the water in the water collection tank 23, lifting the retaining ring 30 upwards can open the outlet 25 and release the water in the water collection tank 23. After the retaining ring 30 moves upwards, it presses the spring 29. When the retaining ring 30 is released, under the action of the spring 29, the retaining ring 30 can seal the outlet 25 again.
[0041] Specifically, an observation window 31 is provided on the outer wall of the tank 1, and a transparent cover plate 32 is fixedly connected to the inner wall of the observation window 31.
[0042] The above technical solution allows operators to easily observe the settling of the liquid inside the tank 1 through the transparent cover 32.
[0043] In use, the liquid to be settled is fed into the tank 1 through the feed valve 3, and the flocculant is fed into the feed hopper 11. The flocculant entering the feed hopper 11 enters the cavity 9 through the feed pipe 10. The motor 5 is started, driving the rotating shaft 6 to rotate, and the feed port 14 rotates. When the feed port 14 rotates to the position that is in contact with the discharge port 12, the flocculant in the cavity 9 enters the discharge chamber 13 through the discharge port 12 and the feed port 14. When the feed port 14 rotates to a position away from the discharge port 12, the discharge port 12 is blocked by the outer wall of the rotating shaft 6 to prevent continuous discharge from the discharge port 12. The flocculant in chamber 13 is discharged from several discharge ports 15, allowing for intermittent and quantitative flocculant addition. This avoids excessive flocculant addition at one time, which could cause the flocculant to clump together in the liquid. The flocculant discharged from the discharge ports 15 falls onto the guide plate 16. Guided by the inclined surface at the top of the guide plate 16, the flocculant is further dispersed, resulting in a more uniform distribution of the flocculant into the liquid. Simultaneously, the rotating shaft 6 drives the stirring rod 7 to rotate, stirring the flocculant in the liquid and accelerating the flocculation of impurities. The float plate 20 causes the lower pressure plate 21 to float on the liquid surface, and the limiting strip 1... 8. With the limiting slot 19, the float 20 is suitable for use in different water depths. The counterweight 22 ensures that part of the pressure plate 21 is below the liquid surface. By setting the top of the float 20 as an incline, the added flocculant is prevented from accumulating on the float 20. When the rotating shaft 6 rotates, it drives the float 20 to rotate, causing the pressure plate 21 to rotate. The arc-shaped surface of the outer wall of the pressure plate 21 forms downward pressure on the liquid, preventing the added flocculant from floating on the surface of the liquid, thereby accelerating the fusion of the flocculant and the liquid. The transparent cover 32 allows operators to easily observe the sedimentation of the liquid in the tank 1. In the case of a drop, the spring 29, in conjunction with the retaining ring 30, keeps the retaining ring 30 in contact with the outlet 25, sealing the bottom of the water collection tank 23. Cold and warm water can be filled into the water collection tank 23 through the inlet 24, which facilitates the temperature regulation of the tank 1. This is suitable for the settling of temperature-sensitive liquids. When it is necessary to replace the water in the water collection tank 23, lifting the retaining ring 30 will open the outlet 25 and release the water in the water collection tank 23. After the retaining ring 30 moves upward, it presses the spring 29. When the retaining ring 30 is released, the spring 29 will cause the retaining ring 30 to seal the outlet 25 again.
