Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sedimentation tank, concretely to a high density sedimentation tank of micro vortex coagulation without mechanical stirring. BACKGROUND

[0002] The sedimentation tank is a structure applied to various fields, and is mainly used for removing suspended matters, inorganic impurities or other solid matters in water. According to the different water flow directions, the sedimentation tank can be divided into two categories of horizontal sedimentation tank and vertical sedimentation tank, and the horizontal flow type sedimentation tank is the most common type in the sedimentation tank, and has simple structure, good sedimentation effect and stable working performance. The sedimentation effect of this type of sedimentation tank is mainly improved by controlling the water flow speed and the water residence time in the tank. The horizontal flow type sedimentation tank usually has a large floor area, but if a mud scraper or other measures are added, the working efficiency can be improved. The vertical flow type sedimentation tank has the characteristics of small floor area and easy mud discharge, but has a large depth, difficult construction and relatively high cost. This type of sedimentation tank is suitable for treating small water quantity in a sewage treatment plant. The inclined pipe sedimentation tank greatly improves the sedimentation efficiency, shortens the sedimentation time and reduces the sedimentation tank volume by adding inclined plates or inclined pipes in the tank. However, the inclined plates and inclined pipes are easy to scale and form long biofilms, and produce dregs, so regular maintenance work is required. The tank body plane of the sedimentation tank can be circular or square. The sedimentation tank is widely used in wastewater treatment. Not only can a primary sedimentation tank be arranged before an aeration tank to reduce the suspended matter content in wastewater and reduce the biological treatment load, but also a secondary sedimentation tank can be arranged after the aeration tank to intercept active sludge. In addition, a chemical sedimentation tank can be arranged after the secondary treatment, that is, a coagulant is added in the sedimentation tank to improve the removal efficiency of organic matters that are difficult to biodegrade, substances that can be oxidized and color-producing substances. The sedimentation tank as an important water treatment facility directly affects the purification effect of water quality. Through reasonable design and operation, the suspended matters and other impurities in water can be effectively removed to provide protection for subsequent water treatment processes.

[0003] The traditional high-density sedimentation tank needs more mechanical equipment to treat wastewater, has large energy consumption, does not meet the environmental protection concept of energy saving and emission reduction, and has great difficulty in later maintenance due to the large number of mechanical equipment.

DETAILED DESCRIPTION

[0019] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a mechanical stirring-free micro-vortex coagulation high-density sedimentation tank, including first sedimentation tank 1 and stirring tank 2 and sludge collection tank 3 and second sedimentation tank 4, first sedimentation tank 1 side is equipped with stirring tank 2, first sedimentation tank 1 side away from stirring tank 2 is equipped with sludge collection tank 3, stirring tank 2 side is equipped with second sedimentation tank 4, and the inner wall of stirring tank 2 side is rotatably connected with water storage box 5 by mounting bracket;

[0020] The inner wall of the mixing tank 2 is symmetrically fixedly connected to the support blocks 6 below the water storage box 5. The upper surfaces of the two support blocks 6 are fixedly connected to the first springs 7. The other ends of the two first springs 7 are fixedly connected to the stirring plate 8. The lower surface of the water storage box 5 is fixedly connected to the top rod 9 relative to the stirring plate 8, and the top rod 9 abuts against the stirring plate 8. The interior of the mixing tank 2 is symmetrically opened with a limiting cavity.

[0021] The inner walls of both limiting cavities are slidably connected to limiting blocks 10. The outer wall of the water storage box 5 is provided with limiting holes 11 through the limiting blocks 10. One end of each of the two limiting blocks 10 extends into the corresponding limiting hole 11. The inner bottom wall of the water storage box 5 is inclined, and the two limiting blocks 10 are semi-circular.

[0022] The first sedimentation tank 1 has a hole on one side of the outer wall of the mixing tank 2 and is fixedly connected to a first connecting pipe 12, with one end of the first connecting pipe 12 extending into the mixing tank 2. The first sedimentation tank 1 has a hole on one side of the outer wall of the sludge collection tank 3 and is fixedly connected to a second connecting pipe 13, with one end of the second connecting pipe 13 extending into the sludge collection tank 3. The height of the first connecting pipe 12 is higher than that of the second connecting pipe 13, so that the wastewater after preliminary sedimentation can be discharged into the mixing tank 2 through the first connecting pipe 12. Flocculant is added to the mixing tank 2 for mixing, and sludge is discharged into the sludge collection tank 3 through the second connecting pipe 13 for collection.

[0023] The mixing tank 2 has holes on one side of the outer wall of the second sedimentation tank 4 and is fixedly connected to a third connecting pipe 14. One end of the third connecting pipe 14 extends into the second sedimentation tank 4, so that the wastewater in the mixing tank 2 can be discharged into the second sedimentation tank 4 and the wastewater containing the mixed flocculant can be discharged into the second sedimentation tank 4 for sedimentation.

[0024] The second sedimentation tank 4 has a hole on one side of the outer wall of the sludge collection tank 3 and is fixedly connected to a fourth connecting pipe 15. One end of the fourth connecting pipe 15 extends into the sludge collection tank 3. The second sedimentation tank 4 has a hole on the outer wall away from the sludge collection tank 3 and is fixedly connected to a drain pipe 16. The height of the drain pipe 16 is higher than that of the fourth connecting pipe 15, so that the sludge can be discharged into the sludge collection tank 3 for collection using the fourth connecting pipe 15, and the treated sewage can be discharged through the drain pipe 16.

[0025] The sludge collection tank 3 has holes on one side of its outer wall and is fixedly connected to a sewage pipe 17, which facilitates the discharge of sludge through the sewage pipe 17 and the discharge of sludge into the sludge collection tank 3 for collection.

[0027] Specifically, when using this utility model, sewage is discharged into the first sedimentation tank 1 for sedimentation. The sludge in the sewage settles to the bottom of the first sedimentation tank 1, while the clear water floats on the upper layer of the first sedimentation tank 1. The sedimented upper layer of sewage is discharged into the mixing tank 2 through the first connecting pipe 12, and then the sludge is discharged into the sludge collection tank 3 through the second connecting pipe 13 for collection. Then, flocculant is added to the mixing tank 2 to mix the sewage with the flocculant. When the sewage enters the mixing tank 2 through the first connecting pipe 12, the sewage enters the water storage box 5 for accumulation. Since the bottom wall of the water storage box 5 is inclined, one end of the water storage box 5 is heavier. When the sewage in the water storage box 5 reaches a certain amount, the heavier end of the water storage box 5 rotates downward and spills out the sewage inside. At the same time, the water storage box 5 is pressed downward by the top rod 9 to press the mixing plate 8 and press down. When the water in the water storage box 5 is discharged, the water storage box 5 is relatively light. The first spring 7 pushes the stirring plate 8 and the top rod 9 to move upward. When the stirring plate 8 moves, it pushes the sewage and flocculant in the stirring tank 2 to mix. The top rod 9 pushes the water storage box 5 to rotate in the opposite direction. When the water storage box 5 rotates back to its original position, the second spring 18 pushes the limiting block 10 to move into the limiting hole 11 to limit and fix the water storage box 5. The water storage box 5 continues to collect sewage. The sewage after stirring is discharged into the second sedimentation tank 4 through the third connecting pipe 14 for secondary sedimentation. The flocculated sludge accumulates at the lower end of the second sedimentation tank 4, and the clear water is located on the upper layer of sewage. The treated sewage is discharged through the drain pipe 16, and the sludge is discharged into the sludge collection tank 3 through the fourth connecting pipe 15 for collection. The collected sludge can be discharged through the sewage pipe 17.
