Description

Technical Field

[0001] This utility model relates to the field of titanium liquid sedimentation and purification technology, and in particular to a black titanium liquid sedimentation and purification device. Background Technology

[0002] In the sulfuric acid process for titanium dioxide production, a polymeric flocculant is used in the sedimentation process of the black titanium liquor. After adding the flocculant, sedimentation is generally achieved through static settling, followed by extraction of the supernatant. However, the position of the extraction tube cannot be precisely adjusted during extraction, resulting in either some supernatant remaining in the sediment or only a portion of the sediment being extracted, leading to low solid-liquid separation efficiency. To improve separation efficiency, rapid sedimentation and purification can be achieved by filtration of the titanium liquor under negative pressure. However, after filtration, the sediment can only be removed from the top of the sedimentation tank, making discharge inconvenient and requiring improvement. Summary of the Invention

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a black titanium liquid sedimentation and purification device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A black titanium liquid sedimentation and purification device includes a sedimentation tank. The top of the sedimentation tank has a feeding port, and the bottom of the sedimentation tank is connected to an extension pipe. The extension pipe is longitudinally arranged and closed at its bottom end. A discharge port is located at the bottom of the side of the extension pipe, and a first suction pump is connected to the discharge port. A filter cartridge is longitudinally arranged inside the extension pipe, and the top and bottom of the filter cartridge are both closed. An upper sealing ring and a lower sealing ring are respectively fitted onto the top and bottom of the circumference of the filter cartridge. The upper or lower sealing ring can be sealed to the extension pipe above the discharge port. The bottom of the filter cartridge is connected to a connecting pipe that communicates with its own internal cavity. The connecting pipe longitudinally penetrates the bottom end of the extension pipe and is sealed to the bottom end of the extension pipe. The bottom end of the connecting pipe is connected to a second suction pump via a flexible hose. A telescopic cylinder is longitudinally installed at the bottom of the extension pipe, and the piston rod of the telescopic cylinder penetrates the bottom end of the extension pipe and is sealed to the bottom end of the extension pipe. The piston rod of the telescopic cylinder is connected to the filter cartridge.

[0006] Furthermore, an agitator is installed inside the settling tank, and a motor for driving the agitator is installed on the top of the settling tank.

[0007] Furthermore, the filter cartridge has multiple filter holes on its circumferential surface, and a filter cloth is fitted onto the circumferential surface of the filter cartridge.

[0008] The beneficial effects of this utility model are as follows: by adjusting the filter cylinder to different heights, the functions of sedimentation, filtration or solid waste discharge can be realized, and the liquid and solid can be completely separated. Both the liquid and the solid are discharged from the bottom of the sedimentation tank, which effectively increases the convenience of material discharge. The specific method will be described in the embodiments. Attached Figure Description

[0013] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0014] like Figures 1-3As shown, the black titanium liquid sedimentation and purification device includes a sedimentation tank 1. A feeding port 11 is provided at the top of the sedimentation tank 1, and an extension pipe 12 is connected to the bottom of the sedimentation tank 1. The extension pipe 12 is longitudinally arranged and closed at its bottom end. A discharge port 13 is provided at the bottom end of the side of the extension pipe 12, and a first suction pump 2 is connected to the discharge port 13. A filter cylinder 3 is longitudinally arranged inside the extension pipe 12. The top and bottom of the filter cylinder 3 are both closed. Several filter holes 31 are opened on the circumferential surface of the filter cylinder 3. An upper sealing ring 4 and a lower sealing ring 5 are respectively fitted onto the top and bottom of the circumferential surface of the filter cylinder 3. A filter cloth 6 is fitted onto the filter cartridge 3. The upper sealing ring 4 or the lower sealing ring 5 can be sealed to the extension pipe 12 above the discharge port 13. The bottom of the filter cartridge 3 is connected to a connecting pipe 32 that is in communication with its own inner cavity. The connecting pipe 32 passes through the bottom end of the extension pipe 12 longitudinally and is sealed to the bottom end of the extension pipe 12. The bottom end of the connecting pipe 32 is connected to a second suction pump 8 through a hose 7. A telescopic cylinder 9 is installed longitudinally at the bottom of the extension pipe 12. The piston rod of the telescopic cylinder 9 passes through the bottom end of the extension pipe 12 and is sealed to the bottom end of the extension pipe 12. The piston rod of the telescopic cylinder 9 is connected to the filter cartridge 3.

[0015] refer to Figure 1 When settling the black titanium liquid, keep the first sealing ring sealed to the extension tube 12, add titanium liquid and flocculant from the feed port 11, and let it settle for a period of time.

[0016] refer to Figure 2 After settling, the upper part of the filter cylinder 3 is driven to rise outside the extension pipe 12 by the telescopic cylinder 9, and the second sealing ring is kept sealed to the extension pipe 12. The second suction pump 8 is turned on, and the filtrate is discharged out of the settling tank 1 through the filter cylinder 3.

[0017] refer to Figure 3 After filtration is completed, the filter cartridge 3 is driven to extend completely beyond the extension tube 12 by the telescopic cylinder 9. At this time, neither the first sealing ring nor the second sealing ring is in contact with the extension tube 12. The settled sediment falls into the bottom of the extension tube 12 under the action of gravity. The first suction pump 2 is turned on to suction the sediment.

[0018] In this embodiment, an agitator 10 is installed inside the settling tank 1, and a motor 101 for driving the agitator 10 is installed on the top of the settling tank 1. Installing the agitator 10 can effectively accelerate the settling speed.
