[0001] The utility model relates to the technical field of wastewater treatment, in particular to synthetic rutile wastewater sedimentation equipment. Background Art

[0002] Synthetic rutile refers to a titanium-rich raw material produced by chemically removing most of the iron from ilmenite. Its composition and structural properties are identical to natural rutile. Its TiO2 content fluctuates between 91% and 96%, depending on the processing technique. It is a high-quality substitute for natural rutile and is widely used in the production of chloride-process titanium dioxide, as well as titanium tetrachloride, titanium metal, enamel products, welding rod coatings, and artificial rutile yellow pigment. The production of synthetic rutile generates a large amount of wastewater. Proper wastewater treatment not only addresses environmental concerns but also allows for wastewater reuse, reducing production costs. Currently, the first step in treating synthetic rutile wastewater is sedimentation. Flocculants are often added directly before sedimentation. This inadequate mixing of the flocculant with the wastewater results in poor sedimentation, impacting treatment efficiency. Therefore, there is a need for a synthetic rutile wastewater sedimentation device that ensures thorough mixing of the wastewater with additives, achieving optimal sedimentation and improving treatment efficiency.

[0007] Furthermore, the lower end of the rotating shaft is connected to the input end of the reducer fixedly connected to the buffer box, and the output end of the reducer is fixedly connected to the scraper through a connecting shaft.

[0008] Furthermore, a plurality of connecting rods are fixedly connected to the upper inner portion of the sedimentation tank, and the connecting rods are fixedly connected to the annular baffle.

[0009] Furthermore, a valve and a booster pump are fixedly connected to the medicine delivery pipe.

[0010] Furthermore, the lower end of the sedimentation tank is arranged to be inclined downward toward the mud discharge pipe, and the lower end of the mud scraper is shaped in accordance with the bottom of the sedimentation tank.

It should be noted that, in this embodiment, in order to improve the processing efficiency, two downpipes 12 are fixedly connected to the lower end of the deflector box 4 .

[0021] To prevent continued water inflow from affecting the already clarified water in the upper portion of the sedimentation tank 1, a buffer tank 13 is fixedly connected to the lower portion of the downpipe 12, with the lower edge of the buffer tank 13 being lower than the downpipe 12. To ensure that the wastewater entering the sedimentation tank 1 is fully mixed with the flocculant and sodium carbonate, thereby enhancing the sedimentation effect, a stirring blade 16 is fixedly connected to the rotating shaft 15 below the downpipe 12. To prevent the scraper 18 from rotating too fast when driven by the rotating shaft 15, the lower end of the rotating shaft 15 is connected to the input end of a reducer 17 fixedly connected to the buffer tank 13. The output end of the reducer 17 is fixedly connected to the middle portion of the upper end of the scraper 18 via a connecting shaft.

[0022] To prevent impurities floating on the water surface in the sedimentation tank from entering the clean water tank 2, a number of connecting rods are fixedly connected to the upper inner portion of the sedimentation tank 1, and the connecting rods are fixedly connected to the annular baffle 3. It should be noted that the upper edge of the annular baffle 3 is higher than the upper edge of the sedimentation tank 1, and the lower edge of the annular baffle 3 is lower than the lowest point of the jagged shape of the sedimentation tank 1, so as to prevent floating impurities from passing through the annular baffle 3.

[0025] The working process of this embodiment is as follows:

[0026] In the process of treating synthetic rutile wastewater, the wastewater source is connected to the wastewater pipe 6, and the flocculant liquid is first prepared in the first liquid distribution box 7, and the sodium carbonate liquid is prepared in the second liquid distribution box 8. Then, the valve on the wastewater pipe 6 is started to operate, so that the wastewater enters the baffle box 4 from the wastewater pipe 6. At the same time, the valve 10 is opened and the booster pump 11 is started to operate, so that the prepared flocculant is mixed with sodium carbonate into the wastewater.

At the same time, the reducer 17 drives the scraper 18 to rotate to scrape the sludge settled at the bottom of the sedimentation tank 1. The sludge enters the sludge discharge pipe 19. As the water level continues to rise, the clean water continues to enter the clean water tank 2 from the serrations on the upper edge of the sedimentation tank 1, and is discharged from the drain pipe 20 for the next step of treatment. The impurities floating on the water surface are blocked by the annular baffle 3 to prevent them from entering the clean water tank 2.
