A stirring mechanism is provided in the circular barrel 5. The stirring mechanism can mix the circulating water and the chemical as evenly as possible and make the circulating water flow in the circular barrel 5. When the circulating water overflows the circular barrel 5, it can flow into the flow box 1. Through the arrangement of the rectangular frame 4, after the circulating water is discharged from the circular barrel 5, the oil will float on the water. The rectangular frame 4 can block the oil stains in the circulating water in the rectangular frame 4, and the water flows from the lower side of the rectangular frame 4 to the flow box 1 outside the rectangular frame 4. After the water overflows the water guide groove 6, it can be discharged from the flow box 1 from the water guide groove 6.

[0022] The lower side of the flow box 1 is connected to a sewage tank 10, and sewage pipes 11 are provided at both opposite ends of the sewage tank 10. The sewage pipes 11 are provided with valves. When there is a lot of oil and dirt, the feed from the feed pipe 8 is stopped, and the water and oil in the flow box 1 are discharged from the sewage pipe 11.

[0023] A manhole 12 is provided on the flow box 1 , and a manhole cover 13 is provided on the manhole 12 , so that workers can conveniently enter the flow box 1 to perform maintenance inside.

[0024] Example 2: A chemical degreaser for circulating water used in steelmaking, comprising a flow box 1 with an upward opening, the flow box 1 being arranged on a plane, and a walking platform 2 being provided on the upper side of the flow box 1. Workers move over the flow box 1 via the walking platform 2 to facilitate the addition of reagents. A rectangular frame 4 with upper and lower openings is provided in the flow box 1 via a fixing rod 3. The upper side of the rectangular frame 4 is lower than the upper side of the flow box 1. A circular barrel 5 with an upward opening and fixed to the flow box 1 is provided in the rectangular frame 4. When adding reagents on the walking platform 2, the reagents are dropped into the circular barrel 5.

[0025] A water guide groove 6 is provided on the inner side of the flow box 1 and is lower than the rectangular frame 4. A drain pipe 7 is connected to the water guide groove 6. The lower end of the circular barrel 5 is connected to a feed pipe 8 extending from the outside of the flow box 1. A valve is provided on the feed pipe 8. A tee pipe 9 is provided at one end of the feed pipe 8 extending into the circular barrel 5. The circulating water that needs to be degreased enters the circular barrel 5 through the feed pipe 8 and can react chemically with the reagent. A stirring mechanism is provided in the circular barrel 5.

[0026] The stirring mechanism includes a transmission column 15 vertically arranged on the other two end sides of the tee pipe 9 through the rotating shaft 14, and a circular block 16 is coaxially sleeved on the transmission column 15. The side of the circular block 16 is on the side of the outlet of the tee pipe 9, and a plurality of groups of first push plates 17 are provided on the outer diameter surface of the circular block 16. The spacing between the plurality of first push plates 17 is equal. The first push plates 17 are arranged horizontally. When the circulating water in the feed pipe 8 is discharged from the tee pipe 9, it can push the transmission column 15 to rotate through the first push plates 17 under the impact of the water flow. Two symmetrical second push plates 18 are provided on the transmission column 15 on the upper side of the circular block 16. During the rotation, the second push plates 18 can stir the water flow in the circular barrel 5. A bearing 19 is sleeved on the upper end of the transmission column 15, and a fixed plate 20 is fixedly connected to the outer side of the bearing 19. A ratchet device provided on the fixed plate 20 is connected to the transmission column 15 extending to the top of the bearing 19, so as to limit the rotation direction of the transmission column 15 by the ratchet device;

[0027] The stirring mechanism can mix the circulating water and the reagent as evenly as possible and make the circulating water flow in the circular barrel 5. When the circulating water overflows the circular barrel 5, it can flow into the flow box 1. Due to the arrangement of the rectangular frame 4, after the circulating water is discharged from the circular barrel 5, the oil in the circulating water will float on the water. The rectangular frame 4 can block the oil in the circulating water inside the rectangular frame 4, while the water flows from the lower side of the rectangular frame 4 to the flow box 1 outside the rectangular frame 4. After the water overflows the water guide groove 6, it can be discharged from the water guide groove 6 to the flow box 1;

[0028] The lower side of the flow box 1 is connected to a sewage discharge bin 10, and sewage discharge pipes 11 are provided at opposite ends of the sewage discharge bin 10. The bottom of the sewage discharge bin 10 is tapered so that the material can slide to the sewage discharge pipe 11 during sewage discharge. A valve is provided on the sewage discharge pipe 11. When there is a lot of oil and dirt, the feed from the feed pipe 8 is stopped, and the water and oil in the flow box 1 are discharged from the sewage discharge pipe 11.

[0029] A manhole 12 is provided on the flow box 1, and a manhole cover 13 is provided on the manhole 12, so that the staff can enter the flow box 1 to carry out maintenance inside.

[0030] The walking platform 2 is provided with a feeding port 21 corresponding to the upper and lower sides of the circular barrel 5 .

[0031] Working principle:

[0032] 1. When removing oil from the circulating water, the staff puts the medicine into the circular barrel 5 through the feeding port 21 on the walking platform 2. The circulating water needs to be fed into the circular barrel 5 through the feeding pipe 8. Through the setting of the stirring mechanism, when the circulating water is discharged from both ends of the tee pipe 9, the transmission column 15 can be driven to rotate through the first push plate 17 under the impact of the circulating water, so that the second push plate 18 stirs the circulating water to promote the chemical reaction between the medicine and the circulating water. When the circulating water in the circular barrel 5 is about to overflow the circular barrel 5, it can flow into the flow box 1. After the water in the flow box 1 submerges the lower side of the rectangular frame 4, when the circulating water continues to overflow from the circular barrel 5, since the oil is insoluble in water and floats on the water, the oil stains in the circulating water can be left in the flow box 1 in the rectangular frame 4. After the water in the flow box 1 submerges the water guide trough 6, the circulating water can overflow into the water guide trough 6 and be discharged from the drain pipe 7.

[0033] 2. When the oil in the rectangular frame 4 needs to be discharged, the valve on the drain pipe 11 is opened so that the water in the flow box 1 and the oil in the rectangular frame 4 are discharged from the drain pipe 11 together.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
