Description

Technical Field

[0001] This utility model relates to the field of titanium preparation equipment, specifically to a sedimentation device for improving the recycling rate of titanium dioxide. Background Technology

[0002] After titanium dioxide base material undergoes filtration, washing, pressing and drying processes, some titanium dioxide will remain in the washing water, resulting in waste of titanium dioxide. In order to improve the utilization rate and economic benefits of titanium dioxide, titanium dioxide wastewater sedimentation devices are often used to recover titanium dioxide.

[0003] Currently, titanium dioxide wastewater settling devices typically employ a settling chamber where titanium dioxide settles at the bottom, and a pumping pipe removes the water from the top, separating the titanium dioxide from the water. However, this method requires the pumping pipe to start only after the titanium dioxide has settled and separated from the water, and the pumping process disturbs the lower titanium dioxide sediment, affecting the titanium dioxide recovery rate. To address this issue, Chinese patent CN207111981U discloses a titanium dioxide settling device. However, while this device can separate titanium dioxide from water in wastewater, some of the settled, suspended titanium dioxide adheres to the filter cloth surface during the settling and pumping process. This leads to the waste of titanium dioxide material adhering to the filter cloth, hindering the full recovery of the settled titanium dioxide and reducing its recycling efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sedimentation device that can achieve efficient sedimentation of titanium dioxide in titanium dioxide wastewater, while also fully scraping off the titanium dioxide adhering to the filter cloth sleeve, reducing the waste of titanium dioxide after sedimentation and improving the recycling rate of titanium dioxide.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a sedimentation device for improving the recycling rate of titanium dioxide, including a support frame. Two fixed shafts are symmetrically installed on the inner side walls of the support frame. An open-top recycling tank is installed between the two fixed shafts. A filter screen cylinder is arranged in the middle of the recycling tank. The filter screen cylinder is also wrapped with a filter cloth sleeve. A scraping and mixing assembly is installed in the middle of the top of the support frame. A drive mechanism is arranged at the power input end of the scraping and mixing assembly at the top of the support frame. The scraping and mixing assembly includes a connecting sleeve that passes through the middle of the top of the support frame, a scraper plate installed on the outer wall of the connecting sleeve, and a stirring plate installed on the side of the scraper plate facing away from the filter screen cylinder. The drive mechanism includes a second gear installed on the upper part of the outer wall of the connecting sleeve, a drive motor installed on one side of the top of the support frame, and a first gear installed on the power output end of the drive motor that meshes with the second gear.

[0006] By adopting the above technical solution, when titanium dioxide wastewater and flocculant are put into the recovery tank, the drive motor in the drive mechanism can rotate gear one and gear two. After gear one and gear two rotate, the scraping assembly will rotate, so that the flocculant and titanium dioxide wastewater can be mixed more quickly under the action of the stirring plate in the scraping and mixing assembly, ensuring the settling rate of titanium dioxide. After the titanium dioxide raw material settles, some titanium dioxide will be in a suspended state. As the pumping process proceeds, this suspended titanium dioxide will adhere to the filter cloth sleeve. After the pumping is completed, the scraper will continue to rotate so as to scrape off the titanium dioxide adhering to the filter cloth sleeve before the discharge after pumping, avoiding the waste of titanium dioxide adhering to the filter cloth sleeve during pumping after the titanium dioxide settles.

[0007] Furthermore, a drainage mechanism is also installed at the top of the bracket on one side of the drive mechanism. The drainage mechanism includes a water pump installed on one side of the top of the bracket and a drainage pipe that passes through the connecting sleeve. The drainage pipe is rotatably connected to the connecting sleeve.

[0008] By adopting the above technical solution, the water pump is mainly used to extract water from the settled titanium dioxide wastewater.

[0009] Furthermore, a connecting column is installed between the drain pipe and the filter screen cylinder, and the connecting column is distributed in a ring around the outside of the drain pipe.

[0010] By adopting the above technical solution, the connecting column and the drain pipe can be used to reliably install the filter screen cylinder.

[0011] Furthermore, a gap is reserved between the bottom end of the drain pipe and the bottom end of the filter screen cylinder, and the filter screen cylinder has a porous structure.

[0012] By adopting the above technical solution, it is ensured that the bottom end of the drain pipe will not be excessively blocked by the filter screen.

[0013] Furthermore, an overflow trough is installed on the upper part of the inner wall of the recycling tank, and an overflow hole is opened on the lower part of the side wall of the overflow trough.

[0014] By adopting the above technical solution, the overflow tank is mainly used to add titanium dioxide wastewater into the recycling tank, and the overflow hole can ensure that the titanium dioxide wastewater remaining in the overflow tank falls completely.

[0015] Furthermore, a discharge pipe with a built-in valve is installed at the bottom center of the recycling tank, and an operation panel is installed on one side wall of the support.

[0016] By adopting the above technical solution, the titanium dioxide that has settled in the recycling tank can be conveniently discharged under the action of the discharge pipe.

[0017] Furthermore, the control panel is electrically connected to both the water pump and the drive motor.

[0018] By adopting the above technical solution, the operation panel mainly controls the convenient start and stop of the water pump and the drive motor by controlling the on and off of the control circuit.

[0019] Furthermore, the scraper is attached to the outer wall of the filter cloth sleeve, and the stirring plate is welded to the scraper.

[0020] By adopting the above technical solution, it can be ensured that the scraper can fully scrape off the titanium dioxide adhering to the outside of the filter cloth sleeve.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] This invention, through the coordinated design of the drive mechanism and the scraping and mixing component, enables the sedimentation device to rotate gear two by the drive motor in the drive mechanism after sedimentation and pumping. This rotation of gear two, in turn, causes the connecting sleeve, scraper, and stirring plate in the scraping and mixing component to rotate. This allows the scraper to fully scrape off the titanium dioxide adhering to the outside of the filter cloth sleeve while the scraper rotates, thus preventing the settled titanium dioxide from settling and adhering to the outside of the filter cloth after pumping. This results in more complete and higher recycling rates of the settled titanium dioxide. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] like Figure 1 , Figure 2 and 4As shown, a sedimentation device for improving the recycling rate of titanium dioxide in this embodiment includes a support 2. Two fixed shafts 3 are symmetrically installed on the inner side walls of the support 2. A top-opening recycling tank 4 is installed between the two fixed shafts 3. A filter screen cylinder 10 is arranged in the middle of the recycling tank 4. The filter screen cylinder 10 is also wrapped with a filter cloth sleeve 9. The filter cloth sleeve 9 is made of microporous filter cloth and is a common component for titanium dioxide filtration. It can achieve reliable separation of titanium dioxide and water after sedimentation and avoid damage during water pumping. A scraping and mixing component 8 is installed in the middle of the top of the support 2. A drive mechanism 1 is provided at the power input end of the scraping and mixing assembly 8. The scraping and mixing assembly 8 includes a connecting sleeve 801 that passes through the middle of the top of the support 2, a scraper 802 installed on the outer wall of the connecting sleeve 801, and a stirring plate 803 installed on the side of the scraper 802 facing away from the filter screen cylinder 10. The drive mechanism 1 includes a second gear 101 installed on the upper part of the outer wall of the connecting sleeve 801, a drive motor 102 installed on one side of the top of the support 2, and a first gear 103 installed on the power output end of the drive motor 102 and meshing with the second gear 101.

[0032] This invention provides a sedimentation device that can efficiently settle titanium dioxide in titanium dioxide wastewater while simultaneously scraping off titanium dioxide adhering to the filter cloth sleeve 9, reducing waste and improving titanium dioxide recycling rate. This solves the problem in existing titanium dioxide sedimentation devices where some suspended titanium dioxide adheres to the filter cloth surface during sedimentation and pumping, leading to waste and hindering full recycling of the settled titanium dioxide, thus reducing the overall recovery rate of titanium dioxide. Regarding the issue of recycling efficiency, the overall approach of this utility model to solve the above problem is as follows: After the titanium dioxide settles and is pumped out, the drive motor 102 in the drive mechanism 1 drives the gear 103 and gear 2 101 to rotate, thereby realizing the rotation of the scraper 802, stirring plate 803 and connecting sleeve 801 in the scraping and mixing assembly 8. The rotating scraper 802 is used to scrape off the titanium dioxide that adheres to the outside of the filter cloth sleeve 9 after settling and pumping out, avoiding the waste of titanium dioxide and improving the recycling rate of titanium dioxide.

[0033] like Figure 1 and 2 As shown, in this embodiment, a drainage mechanism 7 is also installed on the top of the bracket 2 on one side of the drive mechanism 1. The drainage mechanism 7 includes a water pump 702 installed on one side of the top of the bracket 2 and a drainage pipe 701 that passes through the connecting sleeve 801. The drainage pipe 701 is rotatably connected to the connecting sleeve 801.

[0034] As one implementation method, after the titanium dioxide in the titanium dioxide wastewater settles in the recovery tank 4, the water in the filter of the recovery tank 4 is extracted by the water pump 702 and the drain pipe 701, so that the settled titanium dioxide can be centrally stored in the recovery tank 4 for subsequent centralized collection.

[0035] like Figure 2 and 5 As shown, in this embodiment, a connecting post 11 is also installed between the drain pipe 701 and the filter screen cylinder 10, and the connecting post 11 is distributed in a ring around the outside of the drain pipe 701.

[0036] In one implementation, the connecting column 11 connects the filter cylinder 10 and the drain pipe 701 into one unit, so that the filter cylinder 10 has a sufficient supporting foundation when in use.

[0037] like Figure 2 As shown, in this embodiment, a gap is reserved between the bottom end of the drain pipe 701 and the bottom end of the filter cylinder 10, and the filter cylinder 10 has a porous structure.

[0038] As one implementation method, reserving air can ensure that the drain pipe 701 is pumped more smoothly and avoid the filter screen 10 clogging the bottom of the drain pipe 701.

[0039] like Figures 1-3 As shown, in this embodiment, an overflow trough 12 is also installed on the upper part of the inner wall of the recycling tank 4, and an overflow hole 13 is also provided on the lower part of the side wall of the overflow trough 12.

[0040] As one implementation method, when adding titanium dioxide wastewater into the recovery tank 4, in order to avoid causing large disturbances to the added titanium dioxide wastewater, it is necessary to use the overflow tank 12 to add the titanium dioxide wastewater in an overflow manner. The wastewater remaining in the overflow tank 12 after the titanium dioxide wastewater is added can slowly fall into the recovery tank 4 through the overflow hole 13, thus avoiding waste of titanium dioxide wastewater.

[0041] like Figures 1-2 As shown in this embodiment, a discharge pipe 5 with a built-in valve is also installed at the bottom center of the recycling tank 4, and an operation panel 6 is also installed on one side wall of the bracket 2.

[0042] In one implementation method, after the titanium dioxide raw material settles, most of it will fall into the bottom of the recycling tank 4, while a small portion will remain suspended in the liquid. This suspended titanium dioxide will adhere to the filter cloth sleeve 9 as the water is pumped out, and finally be scraped off and fall into the bottom of the recycling tank 4. At this time, opening the discharge pipe 5 can facilitate the discharge of the settled titanium dioxide.

[0043] like Figures 1-2 As shown, in this embodiment, the operation panel 6 is electrically connected to the water pump 702 and the drive motor 102.

[0044] In one implementation, when titanium dioxide wastewater is mixed with flocculant, the drive motor 102 of the drive mechanism 1 and the scraping and mixing component 8 are working, while the drainage mechanism 7 is not working. During subsequent drainage, the water pump 702 in the drainage mechanism 7 is working, while the drive motor 102 in the drive mechanism 1 is not working. By controlling the circuit on and off with the operation panel 6, the drive motor 102 and the water pump 702 can be operated in an orderly manner, thereby ensuring the efficient sedimentation process of titanium dioxide.

[0045] like Figure 2 As shown, in this embodiment, the scraper plate 802 is attached to the outer wall of the filter cloth sleeve 9, and the stirring plate 803 is welded to the scraper plate 802.

[0046] As one implementation method, it can ensure that the scraper plate 802 fully scrapes off the titanium dioxide adhering to the outside of the filter cloth sleeve 9.

[0047] The specific implementation process of this embodiment is as follows: First, connect the device to an external power source. Then, add the titanium dioxide wastewater to be settled into the recovery tank 4 through the overflow tank 12. Simultaneously, add the flocculant directly into the recovery tank 4. Next, drive the drive motor 102 in the drive mechanism 1 to rotate gear one 103 and gear two 101, thereby rotating the stirring plate 803 in the scraping and mixing assembly 8. The rotation of the stirring plate 803 will fully mix the titanium dioxide wastewater and flocculant, thereby accelerating the settling process of the titanium dioxide. In the process, after the titanium dioxide settles, some of the settled titanium dioxide will fall into the bottom of the recycling tank 4, while the other part of the titanium dioxide will be suspended in the wastewater. As the drainage mechanism 7 drains the water from the recycling tank 4, the suspended titanium dioxide will adhere to the outside of the filter cloth sleeve 9. After the water is pumped out, the drive mechanism 1 and the scraping and mixing assembly 8 are started again so that the scraper 802 in the scraping and mixing assembly 8 can scrape off and recycle the titanium dioxide adhering to the outside of the filter cloth sleeve 9, avoiding the waste of titanium dioxide adhesion and ensuring the recycling rate of titanium dioxide.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
