Description

Technical Field

[0001] This utility model relates to the field of recycling equipment technology, and more specifically, to a titanium dioxide recycling device. Background Technology

[0002] In the preparation process of titanium dioxide, after the titanium dioxide base material obtained from the final reaction is filtered, washed, pressed and dried by a filter press, some titanium dioxide will remain in the washing water. If it is discharged directly, it will waste titanium dioxide and also pollute the environment.

[0003] A search revealed Chinese patent application number 202222184413.2, which discloses a sedimentation device for titanium dioxide wastewater, belonging to the field of wastewater treatment technology. The device includes a reaction tank, a stirring mechanism, support legs, and pipes for transporting wastewater and sediment. The stirring mechanism includes a motor, a drive gear, bearings, and a protective cover. The bearings are embedded in the top wall of the protective cover, and a stirring cylinder is fixedly connected to the inner ring of the bearing. The end of the stirring cylinder away from the bearing penetrates the top wall of the reaction tank and extends into the tank. A plurality of stirring blades are evenly spaced on the outer ring of the stirring cylinder, each blade having an inner cavity that communicates with the inner cavity of the stirring cylinder. A plurality of discharge holes communicating with the inner cavities of the stirring blades are also provided on the outer ring of the blades. By providing stirring blades with discharge holes, the flocculant is more thoroughly mixed with the wastewater through stirring, avoiding uneven mixing that could affect the wastewater treatment results. However, the aforementioned patent has the following shortcomings: During use, wastewater and flocculant need to be stirred and mixed inside the reaction tank before sedimentation. This simultaneous mixing and sedimentation within the reaction tank reduces sedimentation efficiency, thereby slowing down titanium dioxide recovery. Furthermore, the precipitate discharged directly through the drain pipe contains a significant amount of water, requiring further dehydration treatment. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the above-mentioned application requires the wastewater and flocculant to be stirred and mixed in the reaction tank before sedimentation. This mixing and sedimentation are carried out simultaneously in the reaction tank, which reduces the sedimentation efficiency and thus the speed of titanium dioxide recovery. In addition, the precipitate discharged directly through the sewage pipe still contains a lot of water and still needs further dehydration treatment. Therefore, this invention proposes a titanium dioxide recovery device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Titanium dioxide recycling equipment to improve the above problems.

[0007] The present invention is as follows:

[0008] The system includes a sedimentation tank, a mounting bracket fixedly installed on the back of the sedimentation tank, a mixing tank that cooperates with the sedimentation tank fixedly installed on the top of the mounting bracket, a connecting pipe connected to the bottom of the mixing tank, a slow-flow tank connected to the bottom of the connecting pipe, and a slow-flow tank installed on the back of the sedimentation tank. Both the side wall of the slow-flow tank and the back of the sedimentation tank have corresponding overflow ports. The sedimentation tank has a squeezing mechanism penetrating its top inside, a filtration mechanism located below the squeezing mechanism inside, a drain pipe located below the filtration mechanism on the side wall of the sedimentation tank, a liquid addition pipe on the side wall of the mixing tank, a cleaning port on the front of the sedimentation tank, and a detachable sealing mechanism for closing the cleaning port on the front of the sedimentation tank.

[0009] As a preferred technical solution of this utility model, the sealing mechanism includes a base fixedly installed on the front of the sedimentation tank, the front of the base is provided with a sealing door, and a plurality of bolts for connecting the base are installed on the sealing door.

[0010] As a preferred technical solution of this utility model, the mixing box includes a box body, a storage hopper and a stirring assembly. The storage hopper is interconnected with the interior of the box body, and a regulating valve for adjusting the flow rate of flocculant is installed on the storage hopper.

[0011] As a preferred technical solution of this utility model, the extrusion mechanism includes a cylinder that is fixedly installed on the top of the sedimentation tank, and the moving end of the cylinder is connected to an extrusion plate that is slidably installed inside the sedimentation tank.

[0012] As a preferred technical solution of this utility model, two guide rods are symmetrically installed on the top of the extrusion plate, which are located on both sides of the cylinder respectively, and the top of the sedimentation tank is provided with a through hole that cooperates with the guide rods and the moving end of the cylinder.

[0013] As a preferred technical solution of this utility model, the filtration mechanism includes a frame, a filter screen is installed inside the frame, and an installation port for the frame to enter and exit is provided through the side wall of the sedimentation tank.

[0014] As a preferred technical solution of this utility model, the inner wall of the sedimentation tank is symmetrically provided with two sliding grooves that cooperate with the frame. One end of the frame is fixedly connected to a sealing plate for closing the installation port. The inner side of the sealing plate is provided with a sealing gasket. The sealing plate is connected to the sedimentation tank by multiple bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. With the setup of a sedimentation tank, mixing tank, connecting pipe, slow-flow tank, and overflow port, flocculant and wastewater are mixed in the mixing tank during use. During the mixing process, the mixture gradually enters the sedimentation tank through the connecting pipe, slow-flow tank, and overflow port for sedimentation. The two stages are carried out separately but can also cooperate to achieve continuous operation without waiting for the mixing to finish before sedimentation. This can effectively improve the sedimentation and recovery speed of titanium dioxide. Moreover, during use, the mixture of wastewater and flocculant overflows into the sedimentation tank through the slow-flow tank and overflow port, and the flow rate is reduced, which can prevent the mixture flowing into the sedimentation tank from impacting the sediment that has already settled inside the sedimentation tank.

[0018] 2. By setting up a squeezing mechanism, a filtering mechanism, a cleaning port, and a sealing mechanism, when it is necessary to remove sediment, the squeezing mechanism squeezes the sediment inside the sedimentation tank, thereby working with the filtering mechanism to squeeze out excess water from the sediment. The squeezed water will be discharged through the drain pipe. After squeezing is completed, the sealing mechanism can be opened to clean the sediment inside the sedimentation tank. This method can squeeze out as much water as possible from the sediment, reducing subsequent processing costs. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figures 1-6As shown, this embodiment proposes a titanium dioxide recycling device, including a sedimentation tank 1. A mounting frame 3 is fixedly installed on the back of the sedimentation tank 1. A mixing tank 2, which cooperates with the sedimentation tank 1, is fixedly installed on the top of the mounting frame 3. A connecting pipe 4, which communicates with the interior of the mixing tank 2, is installed at the bottom of the mixing tank 2. A slow-flowing tank 13, which communicates with the interior of the connecting pipe 4, is installed at the end of the connecting pipe 4 away from the mixing tank 2. The slow-flowing tank 13 is installed on the back of the sedimentation tank 1. Both the side wall of the slow-flowing tank 13 and the back of the sedimentation tank 1 are provided with corresponding overflow ports 14. The overflow ports 14 are configured to... Near the top of the slow-flow tank 13, the flocculant and wastewater are mixed in the mixing tank 2 via the setup of the sedimentation tank 1, mixing tank 2, connecting pipe 4, slow-flow tank 13, and overflow port 14. During use, the flocculant and wastewater are mixed in the mixing tank 2. During this mixing process, the mixture gradually flows through the connecting pipe 4, slow-flow tank 13, and overflow port 14 into the sedimentation tank 1 for sedimentation. These two processes are carried out separately yet can work together to achieve continuous operation, eliminating the need to wait for the mixing to finish before sedimentation. This effectively improves the sedimentation and recovery speed of titanium dioxide. Furthermore, during use, the wastewater... The mixture of flocculant and precipitant overflows into the sedimentation tank 1 through the slow-flow box 13 and overflow port 14, reducing its flow rate and preventing the mixture from impacting the already settled sediment. The sedimentation tank 1 has a compression mechanism 5 extending through its top, and a filter mechanism 8 located below the compression mechanism 5. A drain pipe 6 located below the filter mechanism 8 is installed on the side wall of the sedimentation tank 1. A liquid inlet pipe 7 is installed on the side wall of the mixing tank 2. A cleaning port 9 is opened on the front of the sedimentation tank 1. The front of the sedimentation tank 1 is detachably equipped with a sealing mechanism for closing the cleaning port 9. By setting up a squeezing mechanism 5, a filtering mechanism 8, a cleaning port 9, and a sealing mechanism, when it is necessary to clean out the sediment, the squeezing mechanism 5 squeezes the sediment inside the sedimentation tank 1, thereby working with the filtering mechanism 8 to squeeze out excess water from the sediment. The squeezed water will be discharged through the drain pipe 6. After the squeezing is completed, the sealing mechanism can be opened to clean the sediment inside the sedimentation tank 1, which can squeeze out as much water as possible from the sediment and reduce subsequent processing costs.

[0029] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the sealing mechanism further includes a base 15 fixedly installed on the front of the sedimentation tank 1. A sealing door 16 is provided on the front of the base 15, and multiple bolts 17 for connecting the base 15 are installed on the sealing door 16. It should be noted that during use, the sealing door 16 can be removed by unscrewing the bolts 17, allowing the sediment inside the sedimentation tank 1 to be cleaned through the cleaning port 9. Simultaneously, the sealing door 16 can also seal the cleaning port 9 during use, thereby preventing leakage of liquid from the sedimentation tank 1.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the mixing tank 2 further includes a tank body 201, a storage hopper 202, and a stirring assembly 204. The storage hopper 202 is internally connected to the tank body 201, and a regulating valve 203 for adjusting the flocculant flow rate is installed on the storage hopper 202. The stirring assembly 204 includes a motor installed on the top of the tank body 201, and the output end of the motor is connected to a stirring paddle that is rotatably installed inside the tank body 201. It should be noted that during use, the flocculant is poured into the storage hopper 202, and the flow rate of the flocculant is adjusted by the regulating valve 203 according to the speed of wastewater entering the tank body 201. During use, the motor can drive the stirring paddle to mix and stir the wastewater and flocculant inside the tank body 201.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the squeezing mechanism 5 further includes a cylinder 502 fixedly installed on the top of the sedimentation tank 1. The moving end of the cylinder 502 is connected to a squeezing plate 501 slidably installed inside the sedimentation tank 1. The initial position of the squeezing plate 501 is above the overflow port 14, thereby avoiding affecting the mixing liquid entering the sedimentation tank 1 through the overflow port. Two guide rods 503 are symmetrically installed on the top of the squeezing plate 501, respectively located on both sides of the cylinder 502. A through hole 12 is provided through the top of the sedimentation tank 1, which cooperates with the guide rods 503 and the moving end of the cylinder 502. It should be noted that when it is necessary to clean the sediment, the input of wastewater into the mixing tank 2 is stopped, and then the cylinder 502 is started to drive the squeezing plate 501 to move downward to squeeze and discharge the sediment on the top of the filter mechanism 8. The squeezed water will be discharged into the sedimentation tank 1 through the filter mechanism 8 and the drain pipe 6. During the descent of the squeezing plate 501, the guide rods 503 and the through hole 12 will guide it to ensure stable movement.

[0032] like Figure 2 , Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, the filtration mechanism 8 further includes a frame 801, with a filter screen 802 installed inside the frame 801. A mounting port 10 for the frame 801 to enter and exit is provided through the side wall of the sedimentation tank 1. Two symmetrical sliding grooves 11 are provided on the inner wall of the sedimentation tank 1 to cooperate with the frame 801. A sealing plate 803 for sealing the mounting port 10 is fixedly connected to one end of the frame 801. A sealing gasket 804 is provided on the inner side of the sealing plate 803. The sealing plate 803 is connected to the sedimentation tank 1 by multiple bolts. It should be noted that when cleaning or replacing the filter screen 802, the bolts on the sealing plate 803 can be unscrewed to pull the frame 801 out of the sedimentation tank 1 through the mounting port 10, thus facilitating the cleaning of the filter screen 802. The sliding grooves 11 facilitate the guidance and support of the frame 801. The sealing gasket 804 seals the gap between the sealing plate 803 and the mounting port 10, preventing leakage.

[0033] Specifically, the working principle of this titanium dioxide recovery device is as follows: During use, wastewater is transported to the mixing tank 2 by a delivery pump, so that the wastewater and flocculant are mixed in the mixing tank 2. During the mixing process, the mixture will gradually enter the slow flow tank 13 through the connecting pipe 4, and then overflow into the sedimentation tank 1 through the overflow port 14. The mixture entering the sedimentation tank 1 will be filtered by the filter mechanism 8. Substances that cannot pass through the filter mechanism 8 will settle on the filter mechanism 8. The filtered water will be discharged from the sedimentation tank 1 through the drain pipe 6. When there is too much sediment in the sedimentation tank 1, the delivery of wastewater to the mixing tank 2 will be stopped, and the squeezing mechanism 5 will be started to squeeze the sediment in the sedimentation tank 1. After the sediment is squeezed and dehydrated, the sealing mechanism will be opened and the sediment will be taken out from the sedimentation tank 1 through the cleaning port 9.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
