Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide production technology, and in particular to a waste residue recycling device for titanium dioxide processing. Background Technology

[0002] The large amount of waste generated during titanium dioxide production contains precious metals such as titanium and iron, as well as hazardous substances, posing challenges to the environment and resource recycling. The waste mainly originates from the chloride and sulfate processes. Chlorination process waste contains titanium ore and iron oxide, while sulfate process waste contains impurities such as calcium sulfate, iron, and aluminum. The design of recycling equipment requires the integration of multiple technologies. With the application of intelligent control and energy-saving and environmentally friendly technologies, titanium dioxide waste recycling equipment will become more efficient and environmentally friendly, promoting efficient resource recovery and sustainable development.

[0003] However, in practical application of existing methods, directly pouring the replacement solution into the waste residue makes the reaction difficult to control. The complex composition of the waste residue can lead to overly vigorous or uneven reactions, affecting the recovery efficiency. It may also trigger side reactions, generating harmful substances or precipitates that are difficult to treat, increasing the difficulty of subsequent treatment. Furthermore, excessive dissolution of metal ions reduces the purity of the recovered metals, resulting in excessively high metal concentrations in the waste liquid, increasing the complexity of wastewater treatment. Strong acid or alkali components in the replacement solution may corrode equipment, shortening its lifespan. Moisture in the waste residue may dilute the replacement solution, reducing the reaction rate. Simultaneously, the mixing of metal ions with waste residue components may lead to incomplete separation, reducing the recovery rate. The reaction between the waste residue and the replacement solution may also pose environmental pollution risks, increasing the difficulty of wastewater and waste gas treatment, and further raising environmental protection costs.

[0004] Therefore, this utility model provides a waste residue recycling device for titanium dioxide processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the replacement liquid is directly poured into the waste residue, but the reaction is difficult to control. The complex composition of the waste residue may lead to an overly violent or uneven reaction, which affects the recycling effect. Therefore, this invention proposes a waste residue recycling device for titanium dioxide processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste residue recycling device for titanium dioxide processing includes a limiting box, a base plate fixedly connected to the bottom section of the inner side of the limiting box, a power component arranged on one side of the limiting box, a transmission rod arranged at the power end of the power component, a waste processing component arranged outside the transmission rod, a vortex wheel arranged at the processing end of the waste processing component, the vortex wheel being fixedly connected to the transmission rod, a dry-wet separation component arranged outside the base plate, a second connecting pipe arranged at the discharge end of the dry-wet separation component, a conveying pump arranged in the middle section of the second connecting pipe, a sedimentation component arranged outside the second connecting pipe, and a water outlet pipe arranged at the liquid outlet end of the sedimentation component.

[0008] As a preferred technical solution of this application, the power assembly includes a support frame, which is fixedly connected to the base plate. A motor is provided on the outside of the support frame, and the output end of the motor is fixedly connected to the transmission rod.

[0009] As a preferred technical solution of this application, the waste processing assembly includes a grinding disc, which is fixedly connected to a transmission rod. A stirring frame is provided on the side of the grinding disc away from the motor, and the stirring frame is fixedly connected to the middle section of the transmission rod.

[0010] As a preferred technical solution of this application, the dry-wet separation component includes a mixing tank, which is fixedly connected to a bottom plate. A filter screen is fixedly connected to the inner wall of the mixing tank, and a sealing plate is fixedly connected to the outer side of the middle section of the filter screen. The outlet of the filter screen is fixedly connected to an auger, and the mixing tank is fixedly connected to a second connecting pipe.

[0011] As a preferred technical solution of this application, the sedimentation assembly includes a sedimentation basin, which is fixedly connected to a mixing tank. The sedimentation basin has uniformly distributed sedimentation plates fixedly connected to its inner wall, and one side of the sedimentation basin is fixedly connected to an outlet pipe.

[0012] As a preferred technical solution of this application, a grinding sleeve is fixedly connected to the inner side of the sedimentation basin, and the grinding sleeve is rotatably connected to the grinding disc.

[0013] As a preferred technical solution of this application, a water inlet sleeve is fixedly connected to the top wall of the grinding sleeve, and a uniformly distributed through hole is opened on the inner side of the water inlet sleeve. A first connecting pipe is fixedly connected to the outer side of the through hole, and a diversion pipe is fixedly connected to the outer side of the first connecting pipe.

[0014] Compared with the prior art, this utility model provides a waste residue recycling device for titanium dioxide processing, which has the following beneficial effects:

[0015] 1. The waste residue recovery device for titanium dioxide processing described in this utility model uses a motor and a transmission rod to drive a grinding disc to rotate inside a grinding sleeve, thereby grinding the waste material. Simultaneously, a displacement fluid is injected between the grinding disc and the grinding sleeve through a distribution pipe, a first connecting pipe, and a through-hole, allowing the displacement fluid to contact the ground waste residue. The ground waste residue is then flushed into a mixing tank, which helps improve reaction efficiency. Grinding refines the waste residue, increases the surface area, and allows the displacement fluid to react more evenly with the waste residue, improving metal recovery rate. After grinding, the waste residue is easier to dissolve, simplifying subsequent processing, reducing side reactions and equipment wear, and extending equipment lifespan.

[0016] 2. The waste residue recycling device for titanium dioxide processing described in this utility model uses a transmission rod to drive a stirring rack to rotate within a mixing tank, mixing the leaching solution and the ground waste residue. This increases the reaction surface area, promotes more uniform metal dissolution, and improves metal recovery rate and purity. This process also optimizes waste liquid flowability, simplifies subsequent treatment, reduces harmful substance residue, and enhances overall recycling efficiency.

[0017] 3. The waste residue recycling device for titanium dioxide processing described in this utility model involves a transmission rod driving a vortex wheel to rotate inside the filter screen, thereby forming a vortex to accelerate the sedimentation of waste residue. Simultaneously, a conveying pump extracts the leachate from the mixing tank via a second connecting pipe. During this process, the waste residue and leachate are filtered through the filter screen. The leachate is then conveyed into a sedimentation basin through the second connecting pipe. Subsequently, unfiltered waste residue in the leachate is precipitated through a sedimentation plate. Finally, the leachate is discharged through a water outlet pipe, while the impurities precipitated inside the filter screen are conveyed out by an auger for solid-liquid separation, facilitating subsequent processing.
