Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide preparation, in particular to a leaching liquid processing device for titanium dioxide preparation. Background Art

[0002] In the titanium dioxide production process, a titanium-containing leachate is a key intermediate product. This leachate typically contains titanium as well as various impurities and byproducts, such as unreacted raw materials, dissolved solid particles, colloidal substances, and other soluble impurities. The presence of these impurities and byproducts not only affects the purity of the titanium solution but can also adversely affect the subsequent hydrolysis and calcination steps, leading to reduced product quality, decreased production efficiency, and increased energy consumption.

[0003] To obtain high-quality titanium dioxide, the titanium-containing leachate must be rigorously cleaned and filtered to remove impurities and byproducts. However, traditional cleaning and filtration methods often suffer from inefficiency, incomplete treatment, and high energy consumption. For example, some methods may require the use of large amounts of water and chemical reagents for cleaning, which not only increases processing costs but also may cause environmental pollution. Furthermore, some filtration equipment may be poorly designed or improperly operated, resulting in poor filtration results and inability to effectively remove all impurities.

[0004] Therefore, in order to solve the shortcomings of the above problems, a leachate treatment device for titanium dioxide preparation is proposed. Summary of the Invention

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0029] like Figure 1 As shown, a leachate processing device for preparing titanium dioxide comprises: a processing cylinder 2, a cover plate 1 arranged on the top of the processing cylinder 2, a backflow mechanism arranged on the outer wall of the processing cylinder 2, and a plurality of filter frames 13 arranged in the processing cylinder 2;

[0030] like Figure 2-Figure 3 As shown, the circumferential outer walls of the plurality of filter frames 13 are slidably connected to the circumferential inner wall of the treatment cylinder 2, and the screens at the bottom of the plurality of filter frames 13 are 40 mesh, 80 mesh and 300 mesh from top to bottom respectively;

[0031] The reverse flow mechanism includes two fixed blocks 3, two rotating disks 5 respectively arranged on one side of the two fixed blocks 3, a plurality of connecting rods 15 respectively arranged on one side of the two rotating disks 5, and a motor arranged on the other side of one of the fixed blocks 3;

[0032] One side of the rotating disk 5 is fixedly connected to a plurality of connecting rods 15, the other ends of the plurality of connecting rods 15 are fixedly connected to the circumferential outer wall of the treatment cylinder 2, the rotating disk 5 is rotatably connected to one side of the fixed block 3, the motor is fixedly connected to the other side of one of the fixed blocks 3, and one end of the motor output shaft passes through the fixed block 3 and is fixedly connected to the rotating disk 5;

[0033] The circumferential inner wall of the treatment cylinder 2 is provided with a plurality of limiting grooves, and the circumferential outer walls of the plurality of filter frames 13 are fixedly connected with a plurality of limiting plates 12 . The plurality of limiting plates 12 are respectively located in the corresponding plurality of limiting grooves and are slidably connected.

[0034] It should be noted that by setting up multiple filter frames 13, and the mesh size of the bottom of each filter frame 13 is different (40 mesh, 80 mesh and 300 mesh), multi-stage filtration of the leachate is achieved, which can effectively remove large-particle impurities, fine particles and colloidal substances in the leachate, thereby improving the purity and quality of the leachate, making the multi-stage filtration method more efficient and thorough than single filtration. The backflow mechanism drives the rotating disk 5 to rotate through the motor, which in turn drives the connecting rod 15 and the processing barrel 2 to vibrate or rotate slightly, thereby helping to enhance the fluidity of the leachate during the filtration process and prevent particles from accumulating and clogging on the screen; the limiting groove opened on the circumferential inner wall of the processing barrel 2 is slidably connected to the limiting plate 12 fixed on the circumferential outer wall of the filter frame 13, ensuring the stability and accuracy of the filter frame 13 during the processing process, and also facilitating the disassembly and replacement of the filter frame 13. When it is necessary to clean or replace the screen, it is only necessary to slide the filter frame 13 along the limiting groove without disassembling the entire processing device;

[0035] In addition, when cleaning the filter frame 13, the motor can be started to reverse the treatment drum 2, and the filter frame 13 can be backwashed by reverse water flow to clean impurities on the screen, thereby improving cleaning efficiency.

[0036] like Figure 2As shown, the circumferential inner wall of the cover plate 1 is threadedly connected to the circumferential outer wall of the treatment cylinder 2, a sealing ring is provided between the cover plate 1 and the treatment cylinder 2, the upper surface pipe of the cover plate 1 is connected to the inlet pipe 10, and the bottom pipe of the treatment cylinder 2 is connected to the outlet pipe 14. A protective shell 8 is fixedly connected to one side of one of the fixed blocks 3, and the motor is located in the protective shell 8. The circumferential outer wall of the protective shell 8 is provided with a plurality of penetrating heat dissipation holes 9.

[0037] It should be noted that the circumferential inner wall of the cover plate 1 and the circumferential outer wall of the treatment cylinder 2 are connected by threads and are provided with a sealing ring to ensure the sealing performance of the treatment device during operation. Effective sealing can prevent the leachate from leaking during the treatment process. The inlet pipe 10 facilitates the introduction of the leachate to be treated into the treatment cylinder 2, while the outlet pipe 14 connected to the bottom of the treatment cylinder 2 facilitates the outlet of the treated leachate. The motor is fixed in the protective shell 8, which not only protects the motor from interference and damage from the external environment, such as dust, moisture, etc., but also improves the stability and service life of the motor. The heat dissipation holes 9 help the heat generated by the motor during operation to be dissipated in time to prevent the motor from overheating and damage.

[0038] like Figure 1-Figure 2 As shown,

[0039] Two support rods 4 are fixedly connected to the circumferential outer walls of the two fixed blocks 3 , a first reinforcement rod 6 is fixedly connected between the two support rods 4 on the same side, and two second reinforcement rods 7 are fixedly connected between the two first reinforcement rods 6 .

[0040] It should be noted that by fixing two support rods 4 to the outer circumferential walls of the two fixing blocks 3, providing a first reinforcement rod 6 between the two support rods 4 on the same side, and providing a second reinforcement rod 7 between the two first reinforcement rods 6, the structural stability of the entire device body can be enhanced. This stability is crucial to ensuring the safety and reliability of the equipment under long-term, high-load operation, and avoiding failures and accidents caused by structural loosening or deformation.

[0041] When the present invention is used, the filter frame 13 is slid into the limiting groove of the treatment barrel 2, ensuring that the limiting plate 12 cooperates well with the limiting groove and that the filter frame 13 is stable and does not shake. Then, the cover plate 1 is installed on the top of the treatment barrel 2 by threaded connection, and the sealing ring is installed in place to prevent leakage. The inlet pipe 10 is connected to the cover plate 1, and the connection is tight and leak-free. The cover plate 1 is connected, and the outlet pipe 14 is connected to the bottom of the treatment barrel 2, and the connection is tight and leak-free. When treating the leachate, turn on the motor power supply, start the motor, and make the rotating disk 5 start to rotate, thereby driving the connecting rod 15 and the treatment barrel 2 to vibrate or rotate slightly. The leachate to be treated is slowly injected into the treatment barrel 2 through the inlet pipe 10. The leachate passes through the filtration action of the multi-stage filter frame 13 in the treatment barrel 2, and passes through 40 mesh, 80 mesh and 300 mesh screens in turn to remove large particles of impurities, fine particles and colloidal substances. The filtered leachate is discharged through the outlet pipe 14, collected and stored for subsequent use;

[0042] When cleaning the filter frame 13, the motor is started to reverse the treatment drum 2, and the filter frame 13 can be backwashed by reverse water flow to clean the impurities on the screen.

[0043] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
