Description

Technical Field

[0001] This utility model relates to an environmentally friendly dry tailings disposal equipment for titanium ore beneficiation, belonging to the field of tailings dry tailings disposal technology. Background Technology

[0002] Titanium ore beneficiation typically involves crushing, grinding, and separation (such as gravity separation, magnetic separation, and flotation). Finally, dry stacking equipment is used to reduce the moisture content of the tailings. Dry stacking equipment is mainly used for tailings dewatering and dry stacking treatment. Its core objective is to convert the slurry into a low-moisture solid (dry material) through mechanical dewatering, thereby reducing water consumption, avoiding the environmental risks of tailings ponds, and lowering transportation costs.

[0003] Existing dry discharge equipment for titanium ore beneficiation mainly includes belt filter presses, plate and frame filter presses, centrifugal dewatering machines, hydrocyclones, and combinations with high-frequency dewatering screens. Based on practical experience, the above-mentioned dry discharge devices still have the following technical problems:

[0004] The slurry travels through only one fixed path from feed to discharge, without any parallel processing units, i.e., a single-channel operation mode. The single-channel processing capacity is limited and cannot meet the needs of large-scale mineral processing, easily becoming a bottleneck in the production process.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing an environmentally friendly dry discharge equipment for titanium ore beneficiation, which adopts a dual-channel parallel processing mode for the slurry from feeding to discharging, significantly improving the processing capacity and meeting the needs of large-scale mineral beneficiation.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] An environmentally friendly dry discharge equipment for titanium ore beneficiation includes a distribution box. Filter cartridges connected to the inner cavity of the distribution box are installed on both sides of the box. End plates are installed at the opposite outer ends of the two filter cartridges. The distribution box and end plates are fixedly installed above the frame. Each filter cartridge includes multiple filter bars distributed circumferentially, with filtration gaps between adjacent filter bars. The filter bars have a triangular cross-section. Multiple annular ribs are fitted around the filter bars, and these ribs are fixedly connected to the outer periphery of the filter bars. The annular ribs are evenly spaced. A main shaft passes through the distribution box and the filter cartridges on both sides. A transmission box passes through the center of the main shaft. Helical blades are installed on both sides of the main shaft, including forward and reverse helical blades.

[0009] Furthermore, a feed inlet is provided on the top of the diversion box.

[0010] Furthermore, rotary seals are installed at the connection points between the transmission box and the main shaft on both sides.

[0011] Furthermore, the transmission box is fixed inside the distributor box, and the input end of the transmission box is connected to the motor, which is located outside the distributor box.

[0012] Furthermore, the shaft ends at both ends of the main shaft are inserted into the support frame, and the support frame is embedded with bearing seats that support the rotation of the shaft ends. The support frame is fixed to the outside of the end plate.

[0013] Furthermore, the two filter cartridges are provided with discharge ports at their opposite outer ends, and each discharge port is equipped with a back pressure plate. The back pressure plate is slidably mounted on the main shaft, and the side of the back pressure plate is connected to the pressure regulating component, which is mounted on the main shaft.

[0014] Furthermore, each of the filter cartridges is fitted with a cover.

[0015] Furthermore, a liquid collection hopper is fixedly installed inside the frame, with an opening at the top and a drain outlet at the bottom.

[0016] Furthermore, a set of directional rollers is installed on one side of the bottom of the frame, and a set of universal rollers is installed on the other side, which facilitates the movement of the whole machine.

[0017] Furthermore, the bottom of the frame is also equipped with height-adjustable support feet.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] Tailings slurry enters the diversion box from the feed inlet and is diverted to both sides by the action of the positive and negative spiral blades. During the conveying process, it is dewatered through the gaps in the filter cartridge. After dewatering, the tailings are further dewatered under the reverse pressure provided by the back pressure plate and discharged as low-moisture dry material.

[0020] This invention adopts a dual-channel processing mode, with two processing paths from feeding to discharging, which significantly improves the processing capacity and can meet the needs of large-scale mineral processing.

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown in the figure, this utility model provides an environmentally friendly dry discharge equipment for titanium ore beneficiation, including a diversion box 1, on both sides of the diversion box 1 respectively, filter cylinders 4 connected to its inner cavity, and end plates 5 respectively installed at the opposite outer ends of the two filter cylinders 4. The diversion box 1 and the end plates 5 are both fixedly installed on the top of the frame 2.

[0028] The top of the diversion box 1 is provided with a feed inlet 3. The feed inlet 3 is used for the input of tailings slurry.

[0029] The filter cartridge includes multiple filter strips 41 arranged in a circular pattern, with a filtration gap between adjacent filter strips 41. The cross-section of the filter strip 41 is triangular. Multiple annular ribs 42 are fitted around the periphery of the multiple filter strips 41. The annular ribs 42 are fixedly connected to the periphery of the filter strips 41 and are evenly spaced.

[0030] A main shaft 6 is installed inside the diversion box 1 and the filter cartridges 4 on both sides. A transmission box 11 is installed in the middle of the main shaft 6. Rotary seals 12 are installed at the connection points between the transmission box 11 and the main shaft 6 on both sides to prevent slurry from entering the transmission box 11 and causing corrosion. The transmission box 11 is fixed inside the diversion box 1, and its input end is connected to a motor 13. The motor 13 is located outside the diversion box 1 to prevent slurry from corroding it. The motor 13 drives the main shaft 6 to rotate through the transmission box 11.

[0031] The shaft ends at both ends of the main shaft 6 are inserted into the support frame 8. The support frame 8 is equipped with bearing seats that support the rotation of the shaft ends. The support frame 8 is fixed to the outside of the end plate 5.

[0032] Helical blades 7 are installed on both sides of the main body of the main shaft 6. The helical blades 7 include forward helical blades and reverse helical blades. During rotation, the forward and reverse helical blades divert and transport the tailings slurry in the diversion box 1 to both sides.

[0033] Two filter cylinders 4 have discharge ports at their opposite outer ends, each equipped with a back pressure plate 9. The back pressure plate 9 is slidably mounted on the main shaft 6, and its side is connected to a pressure regulating component 10, which is also mounted on the main shaft 6. The back pressure plate 9 provides reverse pressure during the extrusion process, enabling more effective dewatering of the tailings slurry. The pressure regulating component 10 is used to adjust the dewatering effect and processing speed.

[0034] Each of the filter cartridges 4 is fitted with a cover 18 to prevent the slurry from splashing and polluting the external environment.

[0035] A liquid collection hopper 14 is fixedly installed inside the frame 2. The liquid collection hopper 14 has an opening at the top and a drain port at the bottom. The liquid collection hopper 14 is used to collect the water removed from the filter cartridge 4.

[0036] The bottom of the frame 2 is equipped with a set of directional rollers 15 on one side and a set of universal rollers 16 on the other side, which facilitates the movement of the whole machine.

[0037] The bottom of the frame 2 is also equipped with height-adjustable support feet 17. When the machine is in operation, the support feet 17 are in contact with the ground, and the directional roller assembly 15 and the universal roller assembly 16 are out of contact with the ground.

[0038] The specific working principle of this utility model is as follows:

[0039] Tailings slurry enters the diversion box 1 through the feed inlet 3. The motor 13 drives the main shaft 6 to rotate through the transmission box 11, which in turn drives the spiral blades 7 on both sides to rotate, diverting the tailings slurry in the diversion box 1 to both sides. During the transportation process, the tailings are dewatered through the gaps in the filter cartridge. After dewatering, the tailings are further dewatered under the reverse pressure provided by the back pressure plate 9. After dewatering, the tailings are discharged as low-moisture dry material. The dewatered water is collected by the liquid collection hopper 14 and then output.

[0040] This invention adopts a dual-channel processing mode, with two processing paths from feeding to discharging, which significantly improves the processing capacity and can meet the needs of large-scale mineral processing.
