Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a sewage treatment device and a treatment method for epoxy resin production sewage. Background Art

[0002] The main characteristics of epoxy resin production wastewater are high concentrations of inorganic salts and organic pollutants. In the process of removing organic substances, first, the pH value of the water body needs to be treated. Usually, the pH value needs to be adjusted to about 6, and by adding relevant reagents, the organic substances that can precipitate in the water body can precipitate. In the prior art, when adding reagents, it is not convenient to control the dosage, resulting in a poor reaction effect. And the pollutants in the wastewater are distributed at the bottom, which is not convenient to mix with the reagents, resulting in a poor precipitation effect. At the same time, when feeding materials, the feeding holes are easy to be blocked, affecting subsequent feeding, and impurities are easily attached to the tank wall, affecting subsequent wastewater treatment.

[0035] As Figure 1 - Figure 7 shown, a sewage treatment device for epoxy resin production includes a tank body 1. The inner surface of the tank body 1 is rotatably connected with a rotating cylinder 2 through a bearing. The outer surface of the rotating cylinder 2 is fixedly connected with a base 3. Through holes 4 are formed on the surface of the base 3. A connecting cylinder 5 is communicated with the upper surface of the through hole 4. An elevating frame 6 is slidably connected to the outer surface of the rotating cylinder 2. A connecting column 7 is fixedly connected to the upper surface of the elevating frame 6. An elevating plate 8 is slidably connected to the surface of the through hole 4. A liquid inlet pipe 9 is communicated with the surface of the connecting cylinder 5. A fixing plate 10 is fixedly connected to the upper surface of the connecting cylinder 5. Liquid inlet holes 11 are formed on the surface of the fixing plate 10. A partition plate 12 is fixedly connected to the inner surface of the tank body 1. Positioning holes 14 are formed on the surface of the partition plate 12. The elevating frame 6 drives the top connecting column 7 to rise and fall. The connecting column 7 enters the through hole 4 of the base 3. After the reagent is injected through the liquid inlet pipe 9, the connecting column 7 drives the elevating plate 8 to move upward, pushing the internal reagent into the top connecting cylinder 5.

[0036] The effect is that when the elevating frame 6 moves upward, the elevating frame 6 drives the top connecting column 7 to enter the through hole 4 in the base 3. The reagent is injected through the liquid inlet pipe 9. The elevating frame 6 drives the elevating plate 8 to move upward through the connecting column 7, and the internal reagent can be pushed into the top connecting cylinder 5. The top of the fixing plate 10 contacts the edge at the bottom of the positioning hole 14, which can clean the impurities attached to its surface and avoid blockage.

The fixing frame 20 drives the rotating cylinder 2 to rotate. A check valve is installed inside the liquid inlet pipe 9. The liquid presses the sealing plate 16 to move upward and passes through the liquid inlet hole 11. When the cam 24 rotates, the connecting column 7 moves downward at this time. The arranged first spring 13 drives the lifting plate 8 to move downward. At this time, the medicine in the external medicine tank connected to the liquid inlet pipe 9 can be pumped into the inside of the connecting cylinder 5.

[0039] As Figure 1 - Figure 7 As shown, the inner surface of the positioning hole 14 is rotatably connected with an impeller 25. The upper surface of the impeller 25 is fixedly connected with a connecting rod 26. The outer surface of the connecting rod 26 is slidably connected with a sliding block 27. The outer surfaces of the connecting rod 26 and the sliding block 27 are rotatably connected with a first rotating plate 28 through a rotating shaft. A second rotating plate 29 is rotatably connected between the two first rotating plates 28 through a rotating shaft. The upper surface of the rotating cylinder 2 is fixedly connected with a support rod 30. The outer surface of the support rod 30 near the top is fixedly connected with a first connecting frame 31. The inner surface of the top of the tank body 1 is rotatably connected with a support cylinder 32 through a bearing. The outer surface of the support cylinder 32 is fixedly connected with a second connecting frame 33. The outer surfaces of the first connecting frame 31 and the second connecting frame 33 are fixedly connected with an incomplete toothed ring 34. The outer surface of the connecting rod 26 is fixedly connected with a spur gear 35. The spur gear 35 is meshed with the incomplete toothed ring 34. The outer surface of the support rod 30 near the top is fixedly connected with a first bevel gear 36. The upper surface of the partition plate 12 is fixedly connected with a mounting frame.

A water inlet pipe 42 is communicated with the outer surface of the tank body 1 near the top, and a water outlet pipe 43 is communicated with the outer surface of the tank body 1 near the bottom.

[0042] The effect is that sewage is introduced into the interior of the tank body 1 from the water inlet pipe 42, and after precipitation, it is discharged from the water outlet pipe 43.

The connecting rods 26, the first rotating plate 28 and the second rotating plate 29 rotate to stir and mix the solution inside.

[0045] S2: The rotating rod 21 drives the limiting rod 23 to leave the limiting groove. The cam 24 pushes the lifting frame 6 upward into the through hole 4 in the base 3 and drives the lifting plate 8 to move upward, pushing the internal reagent into the connecting cylinder 5 at the top.

The rotating cylinder 2 drives the connecting cylinder 5 to rotate through the rotation of the base 3, and the connecting cylinder 5 drives the fixing plate 10 on its surface to rotate. The top of the fixing plate 10 contacts the edge at the bottom of the positioning hole 14 to clean the impurities attached to its surface and avoid blockage.

[0049] Working principle: Sewage is introduced into the interior of the tank body 1 through the water inlet pipe 42. The motor 41 is started, and the motor 41 drives the rotating rod 21 to rotate.

At the same time, the support rod 30 drives the first bevel gear 36 to rotate. The first bevel gear 36 drives the second bevel gear 37 to rotate. The second bevel gear 37 drives the third bevel gear 38 to rotate. The third bevel gear 38 drives the support cylinder 32 to rotate. The support cylinder 32 drives the second connecting frame 33 to rotate. The second connecting frame 33 drives the incomplete tooth rings 34 on both sides to rotate. At the same time, it drives the connecting rod 26 to rotate through the spur gears 35 on both sides. At this time, multiple connecting rods 26 rotate. The connecting rod 26 drives the first rotating plate 28 on its surface to rotate. The first rotating plate 28 pulls the second rotating plate 29 to move upward. The second rotating plate 29 drives the first rotating plate 28 at the bottom to move upward. At this time, the sliding block 27 can be driven to move upward. The rotating first rotating plate 28 and second rotating plate 29 can stir and mix the internal solution. When the rotating rod 21 drives the limiting rod 23 to leave the limiting groove, at this time, the cam 24 continues to rotate to the other side and will push the lifting frame 6 upward.

The lifting frame 6 drives the lifting plate 8 to move upward through the connecting column 7 and can push the internal reagents into the connecting cylinder 5 at the top. A check valve is installed inside the liquid inlet pipe 9. The liquid squeezes the sealing plate 16 to move upward and passes through the liquid inlet hole 11. When the water flow passes through the impeller 25, it drives the impeller 25 to rotate. The impeller 25 drives the connecting rod 26 to rotate in the opposite direction. At this time, the internal solution can be continuously mixed to make the solution quickly form a precipitate. When the second connecting frame 33 rotates, it drives the rotating frame 39 to rotate. The rotating frame 39 drives the scraper 40 on its surface to rotate and can clean the inner wall of the tank body 1. When the cam 24 rotates, at this time, the connecting column 7 moves downward. The set first spring 13 drives the lifting plate 8 to move downward. At this time, the reagents in the external reagent tank connected to the liquid inlet pipe 9 can be pumped into the interior of the connecting cylinder 5. Before injecting the reagents, the air inside the connecting cylinder 5 is discharged by repeatedly lifting and lowering the lifting plate 8. Continuing to rotate the rotating rod 21 can drive the connecting column 7 to move out of the through hole 4 opened on the base 3 and drive the rotating cylinder 2 to rotate through the limiting rod 23. The rotating cylinder 2 drives the base 3 to rotate. The base 3 rotates to drive the connecting cylinder 5 to rotate. The connecting cylinder 5 drives the fixing plate 10 on its surface to rotate.
