Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, and in particular relates to a drum-type ore washing device. Background Technology

[0002] During mineral processing, raw ore typically contains a large amount of impurities such as mud and clay, which need to be cleaned and separated by washing equipment. Traditional drum washing machines use a standardized internal structure design, with the entire inner wall of the drum having the same construction and a uniform water supply method, making it impossible to optimize the design for the processing needs of different washing stages.

[0003] This uniform structural design has obvious drawbacks: the material is subjected to the same intensity of treatment from feeding to discharging. This results in insufficient treatment intensity when strong impact is needed to break up the mud clumps in the initial stage, and excessive scouring when gentle washing is required to protect valuable minerals in the later stage. Furthermore, the uniform water supply pressure wastes water resources and prevents precise segmented treatment, leading to low overall washing efficiency and poor washing cleanliness. Utility Model Content

[0025] 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 some embodiments of this utility model, but not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example

[0028] like Figures 1-4 As shown, a drum-type ore washing device includes a drum 1, which is inclined as a whole. The inclination angle is usually 10-15 degrees. This inclination angle ensures the natural flow of materials and provides sufficient residence time for thorough washing.

[0029] The drum 1 is divided into three working areas along the axial direction: feeding section 101, fine washing section 102, and dewatering section 103. The segmented design realizes the washing concept of "coarse washing-fine washing-dewatering". The inner wall of the feeding section 101 is fixedly connected with a rubber liner 2. The surface of the rubber liner 2 is provided with a longitudinal guide groove 3. The rubber material has good wear resistance and elasticity. The longitudinal guide groove 3 guides the material to be conveyed forward quickly, and at the same time facilitates the initial breaking of large mud clumps, preparing for the subsequent fine washing.

[0030] The inner wall of the fine washing section 102 is fixedly connected with a corrugated liner 4. The corrugated shape increases the contact area between the material and the liner, providing a stronger mechanical stirring effect. The trough design is conducive to wastewater collection and discharge.

[0031] The inner wall of the drum 1 is provided with a spiral plate 5 with decreasing pitch. The spiral plate 5 is fixedly connected to the inner wall of the drum 1 and rotates synchronously. The spiral plate 5 has a larger pitch in the feeding section 101, a medium pitch in the fine washing section 102, and the smallest pitch in the dewatering section 103. The decreasing pitch design realizes the gradient control of the material conveying speed. The fast conveying in the front section avoids blockage, and the slow conveying in the rear section ensures thorough washing.

[0032] The fine washing section 102 has several equally spaced first filter holes 6 at the corresponding trough positions, which effectively discharges wastewater while preventing the loss of useful minerals. The inner wall of the dewatering section 103 has several equally spaced second filter holes 7 for final dewatering.

[0033] like Figure 3 and Figure 8 As shown, the segmented water supply device 8 includes a low-pressure main pipe 801 fixedly connected to the support frame 12 and a high-pressure main pipe 802 fixedly connected to the feed hopper 13. The low-pressure main pipe 801 is located in the fine washing section 102, and the high-pressure main pipe 802 is located in the feed inlet section 101. The low-pressure main pipe 801 and the high-pressure main pipe 802 are separated by a sealing plate 803, which is located at the junction of the feed inlet section 101 and the fine washing section 102, ensuring that the two pipes supply water independently and do not interfere with each other. The outer ends of both the low-pressure main pipe 801 and the high-pressure main pipe 802 are fixedly connected. Several equally spaced, staggered fan-shaped nozzles 804 are connected to the roller 1. The fan-shaped nozzles 804 cover the lower area of ​​the roller 1 to ensure that the material receives uniform hydraulic action. The fan-shaped nozzles 804 are fixed to the outer wall of the main pipe by threaded connection. The spray angle is 30 degrees and tilted downward at a 15-degree angle, which covers the 120-degree fan-shaped area at the bottom of the roller 1. This area is the main distribution area of ​​the material. Both ends of the low-pressure main pipe 801 and the high-pressure main pipe 802 are provided with plugs 805. The inner end of the plugs 805 is fixedly connected to the water inlet pipe.

[0034] The inlet pipes 806 of the low-pressure main pipe 801 and the high-pressure main pipe 802 are connected to the same main pump through a branch pipe. A pressure regulating valve is installed on the branch leading to the low-pressure main pipe 801 to reduce the pressure of the high-pressure water flow of the main pump; the branch leading to the high-pressure main pipe 802 directly supplies the pressure of the main pump.

[0035] like Figure 3 As shown, rotating rings 9 are fixedly connected to both ends of the roller 1 along the axial direction. The rotating rings 9 and the roller 1 are an integral structure and rotate synchronously with the roller 1. The outer end of the rotating rings 9 is rotatably connected to a support ring 10. The support ring 10 remains stationary and bears the entire weight of the roller 1.

[0036] like Figures 3-7 As shown, a fixed housing 11 is fixedly connected to the outer end of the support ring 10 near the dewatering section 103. The fixed housing 11 remains stationary when the drum 1 rotates, effectively collecting the rolling sewage. A support frame 12 and a feed hopper 13 are fixedly connected to the outer end of the support ring 10 near the feeding section 101. The support frame 12 provides support for the entire equipment, and the feed hopper 13 is used for material feeding.

[0037] The fixed housing 11 has an opening corresponding to the feed section 101, and a protective cover 14 is fixedly connected to the opening. The protective cover 14 protects the internal gear transmission system from sewage corrosion. A gear ring 15 is fixedly connected to the outer end of the roller 1 at the position corresponding to the protective cover 14. The gear ring 15 rotates synchronously with the roller 1. A pinion 16 is fixedly connected to the outer end of the gear ring 15. The pinion 16 is connected to the output shaft of the drive motor 19 to realize power transmission.

[0038] A support plate 17 is fixedly connected to the outer end of the fixed housing 11, and a frame 18 is fixedly connected to the bottom end of the support plate 17, providing a stable foundation support for the entire equipment. A drive motor 19 is fixedly connected to the top end of the frame 18, and the output shaft of the drive motor 19 is fixedly connected to a pinion 16. The entire transmission system adopts gear reduction transmission, with the drive motor 19 driving the pinion 16 to rotate, and the pinion 16 driving the gear ring 15 and the entire drum 1 to rotate.

[0039] A drain port 20 is fixedly connected to the outer end of the fixed housing 11, and the drain port 20 communicates with the interior of the fixed housing 11. The collected sewage is discharged through the drain port 20. A discharge port 21 is fixedly connected to the outer end of the support ring 10 located at the lower end. The cleaned material is discharged through the discharge port 21.

[0040] During operation, the raw ore enters the feeding section 101 of the drum 1 through the feeding hopper 13. Under the impact of the high-pressure water flow provided by the high-pressure main pipe 802 and the action of the rubber liner 2, it is quickly wetted and initially separated. After entering the fine washing section 102, the corrugated liner 4 and the low-pressure water flow of the low-pressure main pipe 801 provide a suitable washing effect, finely removing the sludge. Finally, after being dewatered through the second filter hole 7 in the dewatering section 103, it is discharged from the discharge port 21. The whole process realizes gradient washing, which improves the washing degree and water resource utilization rate.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
