Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a dual-alkali softening device for wastewater treatment. Background Technology

[0002] Dual-alkali softening is a wastewater treatment method mainly used to remove hardness components (such as calcium and magnesium ions) from water. Its principle is to add alkaline substances such as sodium hydroxide and sodium carbonate to the water, causing the hardness ions in the water to precipitate and precipitate out, thereby reducing the hardness of the water. It is currently commonly used to treat wastewater in wastewater treatment ponds.

[0003] Currently, when performing dual-alkali softening treatment on wastewater in sewage treatment ponds, alkaline chemicals are usually manually added by staff, and traditional stirring arms are used to agitate the wastewater. When the traditional stirring arms agitate the wastewater, it creates a centrifugal state within the treatment pond, and the alkaline chemicals are affected by the centrifugal force, reducing their mixing effect with the wastewater. Furthermore, since the location where the alkaline chemicals are added remains the same, all the chemicals are added in one place, resulting in low contact area and mixing uniformity between the alkaline chemicals and the wastewater, which affects the wastewater treatment effect and efficiency. Utility Model Content

A dual-shaft motor is fixedly connected to the inner wall of the positioning cylinder. A rotating plate is fixedly connected to the top of the dual-shaft motor via a rotating shaft. Two feeding components are fixedly connected to the upper surface of the rotating plate. A sleeve is fixedly connected to the bottom end of the dual-shaft motor.

A submersible motor is fixedly connected to the inner bottom wall of the positioning frame. A rotating rod is fixedly connected to the output end of the submersible motor. Eight reverse-moving stirring arms are fixedly connected to the surface of the rotating rod.

[0007] Preferably, the top end of the rotating rod overlaps with the bottom end of the sleeve, and the positions of the eight forward stirring arms do not correspond to the positions of the eight reverse stirring arms.

[0008] Preferably, a circular limiting seat is fixedly connected to the surface of the sewage treatment tank. A circular limiting groove is formed on the upper surface of the circular limiting seat.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] Reference Figure 1-4 A dual-alkali softening device for sewage treatment includes a sewage treatment tank 1. Two support rods 2 are fixedly connected to the inner wall of the sewage treatment tank 1. A stirring assembly is fixedly connected to the opposite ends of the two support rods 2. The stirring assembly includes a positioning cylinder 3. A dual-shaft motor 4 is fixedly connected to the inner wall of the positioning cylinder 3. A rotating plate 6 is fixedly connected to the top of the dual-shaft motor 4 via a rotating shaft 5. Two feeding assemblies are fixedly connected to the upper surface of the rotating plate 6. A sleeve 7 is fixedly connected to the bottom end of the dual-shaft motor 4. Two horizontal bars 8 are fixedly connected to the surface of the sleeve 7. Vertical bars 9 are fixedly connected to the surface of each of the two horizontal bars 8. Four forward stirring arms 10 are fixedly connected to the surface of the two vertical bars 9. A positioning frame 11 is fixedly connected to the inner bottom wall of the sewage treatment tank 1. A submersible motor 12 is fixedly connected to the inner bottom wall of the positioning frame 11. A rotating rod 13 is fixedly connected to the output end of the submersible motor 12. Eight reverse stirring arms 14 are fixedly connected to the surface of the rotating rod 13.

[0023] The top end of the rotating rod 13 overlaps with the bottom end of the sleeve 7, and the positions of the eight forward stirring arms 10 do not correspond to the positions of the eight reverse stirring arms 14.

[0024] After the alkaline drug is added to the wastewater treatment tank 1 through the dosing component, the dual-shaft motor 4 drives the sleeve 7 to rotate and drives the eight forward stirring arms 10 to rotate clockwise through the horizontal bar 8 and the vertical bar 9. Meanwhile, the submersible motor 12 drives the eight reverse stirring arms 14 to rotate counterclockwise through the rotating rod 13. This allows the wastewater in the wastewater treatment tank 1 to be stirred but not centrifuged, thereby greatly improving the mixing uniformity and contact area between the alkaline drug and the wastewater, and thus improving the treatment effect and efficiency of the wastewater.

[0025] A circular limiting seat 15 is fixedly connected to the surface of the sewage treatment tank 1. A circular limiting groove is opened on the upper surface of the circular limiting seat 15. Two limiting blocks 16 are slidably connected to the inner bottom wall of the circular limiting groove, and the upper surfaces of the two limiting blocks 16 are fixedly connected to the lower surface of the rotating plate 6.

[0026] The circular limit seat 15 and the limit block 16 can ensure the stability of the rotating plate 6 during rotation, and prevent the rotating plate 6 from detaching due to excessive rotation speed.

[0027] The feeding assembly includes a feeding cylinder 17, with a feeding hole at the bottom and a threaded groove at the top. A sealing cap 18 is threaded onto the inner wall of the threaded groove. Feeding frames 19 are fixedly connected to the lower surface of the rotating plate 6 at positions corresponding to the two feeding cylinders 17. A servo motor 20 is fixedly connected to the front of the feeding frame 19. A connecting shaft 21 is fixedly connected to the output end of the servo motor 20. A circular shaft 22 is rotatably connected to the inner rear wall of the feeding frame 19. Several baffle plates 23 are fixedly connected to the surface of the circular shaft 22. Feed holes and discharge holes are respectively opened at corresponding positions on the upper and lower surfaces of the feeding frame 19. The rear end of the connecting shaft 21 extends into the interior of the feeding frame 19 and is fixedly connected to the front end of the circular shaft 22. A circular through hole adapted to the connecting shaft 21 is opened on the front of the feeding frame 19. A through hole is opened at the position corresponding to the feeding hole on the upper surface of the rotating plate 6, and the through hole corresponds to the feeding hole on the upper surface of the feeding frame 19.

[0028] After opening the sealing cover 18 and placing the alkaline drug into the feeding cylinder 17, the alkaline drug will enter the feeding frame 19 through the feeding hole, through hole, and feed hole, and fall between the two adjacent baffle plates 23. The alkaline drug above is blocked by the two filled baffle plates 23 and will not continue to leak downward. When the servo motor 20 drives the circular shaft 22 and the baffle plates 23 to rotate through the connecting shaft 21, the space between the two filled baffle plates 23 rotates, thereby driving the alkaline drug to be discharged into the sewage treatment tank 1 through the discharge hole. The dual-axis motor 4 drives the rotating plate 6 to rotate through the rotating shaft 5, so that the alkaline drug can be rotated for feeding, improving the uniformity of drug feeding.

[0029] Working principle: First, open the sealing cover 18 and put the alkaline drug into the feeding cylinder 17. At this time, turn on the dual-axis motor 4, submersible motor 12 and servo motor 20. After the servo motor 20 starts, it can drive the circular shaft 22 and the baffle plate 23 to rotate through the connecting shaft 21. The alkaline drug falling between two adjacent baffle plates 23 can be discharged directly into the sewage treatment tank 1 through the discharge hole. The dual-axis motor 4 can drive the rotating plate 6 to rotate through the rotating shaft 5, so that the alkaline drug can be rotated and dispensed, improving the uniformity of dispensing. In addition, the setting of the limit block 16 and the circular limit seat 15 can ensure rotation The stability of the moving plate 6 during rotation is ensured, and the dual-shaft motor 4 can also synchronously drive the sleeve 7 to rotate after starting, so that the horizontal bar 8 and vertical bar 9 drive the forward stirring arm 10 to rotate clockwise at a uniform speed. At the same time, the submersible motor 12 can drive the reverse stirring arm 14 to rotate counterclockwise through the rotating rod 13. In conjunction with the forward stirring arm 10, the sewage in the sewage treatment tank 1 can be stirred, and the sewage can be ensured to be free from centrifugal state, so that the alkaline drug and sewage are mixed more evenly, thereby improving the sewage softening effect, reducing the reaction time between alkaline drug and sewage, and improving the treatment efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
