Description

Technical Field

[0001] This utility model relates to the field of flotation tanks, and in particular to a coagulation flotation tank used in water pollution prevention and control. Background Technology

[0002] In the fields of wastewater treatment and related water purification, traditional purification methods often separate the coagulation and flotation processes. The coagulation process usually relies on a dedicated coagulation reactor, where coagulants are added to the wastewater to cause suspended particles and other pollutants in the water to aggregate into larger flocs for better subsequent separation and removal. The flotation process, on the other hand, takes place in a separate flotation device, where tiny air bubbles assist the pollutants in the water, using buoyancy to make them float to the surface for separation and removal.

[0003] In existing technologies, some devices separate coagulation and flotation phases and carry them out in different equipment or areas. This requires a large site space to arrange the corresponding reaction tanks and equipment, which increases the cost of site rental, results in low site utilization, and is not conducive to improving enterprise efficiency. Utility Model Content

[0004] This utility model proposes a coagulation-flotation tank for water pollution prevention and control, aiming to improve the problem of high land occupation and low work efficiency caused by the separation of coagulation and flotation processes in some existing devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coagulation flotation tank for water pollution control includes a tank body. A dissolved air tank is connected to the left side of the tank body. Air supply pipes are fixedly connected to the left and right sides of the dissolved air tank. Multiple horizontal rods are fixedly connected to the top left side of the tank body. A horizontal plate is fixedly connected to the top of the multiple horizontal rods. A motor is fixedly connected to the top of the horizontal plate. An agitator is fixedly connected to the output end of the motor. A flocculation pipe is fixedly connected to the right side of the tank body. A coagulation aid pipe is fixedly connected to the left side of the tank body. A sludge container is fixedly connected to the right side of the tank body.

[0007] As a further description of the above technical solution:

[0008] Multiple support blocks are fixedly connected to the top right side of the pool body, and sprockets are fixedly connected to the right side of the multiple support blocks.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] A connecting plate is fixedly connected to one side of each of the plurality of sprockets, and a scraper plate is rotatably connected to the top of the connecting plate.

[0013] As a further description of the above technical solution:

[0014] The connecting plate has a circular hole inside, and the slag scraper has a circular hole inside.

[0015] As a further description of the above technical solution:

[0016] The connecting plate is internally connected to a limiting roller, and a short shaft is fixedly connected to the right side of the limiting roller.

[0017] As a further description of the above technical solution:

[0018] Multiple short rods are fixedly connected to the outer right side of the short shaft, and a spring is sleeved on the outside of the short shaft.

[0019] As a further description of the above technical solution:

[0020] A cylinder is slidably connected to the outside of the limiting roller, and a rotating block is fixedly connected to the right side of the short shaft.

[0021] This utility model has the following beneficial effects:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a coagulation flotation tank for water pollution control, comprising a tank body 1, a dissolved gas tank 2 connected to the left side of the tank body 1, gas supply pipes 3 fixedly connected to the left and right sides of the dissolved gas tank 2, the gas supply pipes 3 transporting gas from the dissolved gas tank 2 to the tank body 1, multiple horizontal rods 6 fixedly connected to the top left side of the tank body 1, a horizontal plate 7 fixedly connected to the top of the multiple horizontal rods 6, a motor 8 fixedly connected to the top of the horizontal plate 7, and an agitator 9 fixedly connected to the output end of the motor 8, the motor 8 driving the agitator 9 to stir the tank body 1 with added coagulant aid and coagulant accumulator, accelerating the reaction, a flocculation pipe 4 fixedly connected to the right side of the tank body 1, a coagulation aid pipe 5 fixedly connected to the left side of the tank body 1, and a slag container 22 fixedly connected to the right side of the tank body 1.

[0032] Reference Figure 2 and Figure 3 Multiple support blocks 10 are fixedly connected to the top right side of the pool body 1. A sprocket 11 is fixedly connected to the right side of the multiple support blocks 10. A motor 13 is fixedly connected to the right side of the sprocket 11. A chain 12 is rotatably connected to the outside of the sprocket 11. The motor 13 drives the sprocket 11 and the chain 12 to move.

[0033] Reference Figures 2 to 4A connecting plate 14 is fixedly connected to one side of multiple sprockets 11. A scraper 15 is rotatably connected to the top of the connecting plate 14. A circular hole is opened inside the connecting plate 14. A circular hole is opened inside the scraper 15. The circular holes of the connecting plate 14 and the scraper 15 are the same size. A limiting roller 16 is rotatably connected inside the connecting plate 14. A short shaft 18 is fixedly connected to the right side of the limiting roller 16. Multiple short rods 19 are fixedly connected to the outer right side of the short shaft 18. A spring 20 is sleeved on the outside of the short shaft 18. A cylinder 17 is slidably connected to the outside of the limiting roller 16. A groove is provided on the outer right side of the cylinder 17 to facilitate the short rods 19 engaging with the rotating block 21 fixedly connected to the right side of the short shaft 18.

[0034] Working principle: The coagulant and flocculant are added to the tank 1 through the coagulation aid pipe 5 and the flocculant pipe 4, respectively. The motor 8 drives the stirring paddle 9 to stir and mix the wastewater with the added coagulant and flocculant. After effective coagulation reaction, the raw water flows from the bottom of the tank from left to right and enters the dissolved air flotation contact zone. In the contact zone, microbubbles in the water attach to the coagulated suspended solids and are required to enter the separation zone. When the density of the suspended solids is less than that of water, the flocs and bubbles rise to the liquid surface together to form scum. The motor 13 drives the sprocket 11 and the chain 12 to move. The scraper 15 installed on the sprocket 11 scrapes the scum to the scum container 22. The clear water in the lower layer flows by gravity to the clear water tank through the pipe, completing the work.

[0035] When the scraper plate 15 needs to be disassembled, pull the rotating block 21 outward and rotate it so that the short rod 19 outside the short shaft 18 is locked outside the cylinder 17, and the limiting roller 16 leaves the circular hole of the connecting plate 14 and the scraper plate 15. When the replacement is completed and the limiting is required, continue to rotate the rotating block 21 so that the short rod 19 is locked in the groove outside the cylinder 17, thus completing the limiting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
