Description

Technical Field

[0001] This utility model belongs to the field of ore cleaning technology, specifically referring to ore cleaning equipment. Background Technology

[0002] Washing is a crucial step in ore mining and processing, aiming to remove surface dirt and impurities to improve ore grade and subsequent processing efficiency. Tank washing machines, as one of the commonly used washing equipment, play a vital role in processing difficult-to-wash ores due to their strong scrubbing capabilities. However, existing tank washing machines generally suffer from a significant problem: the height of the overflow port remains fixed.

[0003] In actual ore washing, the washing water carries the washed mud and fine particles out of the overflow port. Since the height of the overflow port cannot be adjusted, it is difficult to control the washing effect when conditions such as the flow rate of the washing water, the properties of the ore, and the mud content change. When processing ores with high mud content, the fixed height of the overflow port can easily cause a large number of useful fine particles to be lost along with the washing mud and overflow water, which reduces the ore recovery rate and causes resource waste. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an ore washing device that effectively solves the problem of not being able to flexibly adjust the height of the overflow port.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: ore washing equipment, including a frame and a washing tank, the washing tank being inclinedly and fixedly installed on the frame, two sets of spiral shafts being provided inside the washing tank, a flushing structure being provided above the washing tank, a sealing baffle being slidably provided inside the bottom side wall of the washing tank, an overflow port being provided at the top of the sealing baffle, and a water outlet being provided inside the overflow port that penetrates the sealing baffle and connects to the washing tank for discharging muddy water during the ore washing process;

[0006] Limiting plates are fixed on both sides of the sealing baffle, and a limiting groove matching the limiting plate is opened at the corresponding position on the side wall of the cleaning tank, with the limiting plate embedded in the limiting groove.

[0007] Preferably, a support plate is fixed to the outer wall of the cleaning tank, and a cylinder is fixed to the support plate perpendicular to the bottom of the overflow port. The piston rod of the cylinder is fixedly connected to the center position of the bottom of the overflow port.

[0008] Preferably, an inclined guide plate is provided close to the bottom of the outlet, and a water receiving trough is provided at the bottom of the inclined guide plate. A filter screen is placed at the top opening of the water receiving trough to intercept particulate impurities and some fine minerals in the muddy water.

[0009] Preferably, the guide plate has an inclination angle of 30-45°, with one end connected to the water outlet and the other end extending above the water receiving tank.

[0010] Preferably, the rinsing structure includes a fixing frame, which is installed at equal intervals on the top wall of the cleaning tank. Multiple sets of high-pressure rinsing pipes are installed on the fixing frame, one end of each rinsing pipe is connected to a connecting pipe, and the other end of the connecting pipe is connected to a water inlet pipe.

[0011] Preferably, the upper end of the cleaning tank is provided with a discharge port, and the discharge port is provided with an inclined discharge guide plate.

[0012] The present invention achieves the following beneficial effects by adopting the above structure: By flexibly adjusting the height of the overflow port, the overflow speed and particle size range of the overflow material can be controlled according to the specific conditions of the ore and the state of the washing water flow, effectively reducing the loss of useful fine particles with the overflow water, significantly improving the ore recovery rate, reducing resource waste, and adapting to the ore washing needs of different mud contents and different particle size distributions.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, the ore washing equipment proposed in this utility model includes a frame 1 and a washing tank 2. The washing tank 2 is fixedly installed on the frame 1 at an incline. Two sets of spiral shafts 3 are provided inside the washing tank 2. A flushing structure 4 is provided above the washing tank 2. A sealing baffle 5 is slidably provided inside the bottom side wall of the washing tank 2. An overflow port 6 is provided at the top of the sealing baffle 5. An outlet 7 that penetrates the sealing baffle 5 and connects to the washing tank 2 is provided inside the overflow port 6 for discharging muddy water during the ore washing process.

[0021] like Figure 1 , 2 As shown, limit plates 8 are fixed on both sides of the sealing baffle 5. Limiting grooves 9 matching the limit plates 8 are opened at corresponding positions on the side wall of the cleaning tank 2. The limit plates 8 are embedded in the limiting grooves 9, so that the sealing baffle 5 can slide up and down in the side wall of the cleaning tank 2. A rubber sealing strip is provided at the connection between the limit plates 8 and the limiting grooves 9 to prevent leakage. A support plate 10 is fixed on the outer side wall of the cleaning tank 2. A cylinder 11 is fixed on the support plate 10 perpendicular to the bottom of the overflow port 6. The piston rod of the cylinder 11 is fixedly connected to the center position of the bottom of the overflow port 6. By controlling the intake or exhaust of air in the cylinder 11, the piston rod is driven to extend and retract, thereby driving the overflow port 6 and the sealing baffle 5 to move up and down along the side wall of the cleaning tank 2 to realize the adjustment of the height of the overflow port 6.

[0022] like Figure 1-3As shown, an inclined guide plate 12 is installed below the outlet 7, close to the overflow port 6. A water receiving trough 13 is provided at the bottom of the inclined guide plate 12. A filter screen 14 is installed at the top opening of the water receiving trough 13 to intercept particulate impurities and some fine minerals in the muddy water. There is a drain outlet at the bottom of the water receiving trough 13 to discharge the filtered water. The inclined angle of the guide plate 12 is 30-45°. One end is connected to the outlet 7, and the other end extends to the top of the water receiving trough 13.

[0023] like Figure 1 , 3 As shown, the flushing structure 4 includes a fixing frame 15, which is installed at equal intervals on the top wall of the cleaning tank 2. Multiple sets of high-pressure flushing pipes 16 are installed on the fixing frame 15. One end of the flushing pipe 16 is connected to a connecting pipe 17, and the other end of the connecting pipe 17 is connected to a water inlet pipe 18. Water is sent through the water inlet pipe 18 into the connecting pipe 17 and then to the flushing pipe 16. The nozzles on the flushing pipe 16 spray water onto the ore in the cleaning tank 2 for cleaning.

[0024] like Figure 4 As shown, the upper end of the washing tank 2 is provided with a discharge port 19, and an inclined discharge guide plate 20 is provided at the discharge port 19 to discharge the washed ore.

[0025] In practical use, the ore to be cleaned is placed in the cleaning tank 2, the washing machine is turned on, the spiral shaft 3 rotates, and water is sent through the water inlet pipe 18 to the connecting pipe 17 and then to the flushing pipe 16. The nozzle on the flushing pipe 16 sprays water onto the ore in the cleaning tank 2 to form a washing operation environment.

[0026] By controlling the intake or exhaust of air in cylinder 11, the piston rod is driven to extend and retract, thereby causing the overflow port 6 and the sealing baffle 5 to move up and down along the side wall of the cleaning tank 2, thus adjusting the height of the overflow port 6. According to the characteristics of the ore such as mud content and particle size, the overflow port 6 is adjusted to a suitable height by controlling cylinder 11. When processing ore with high mud content, the height of the overflow port 6 is lowered; when processing ore with larger particle size and low mud content, the height of the overflow port 6 is appropriately raised.

[0027] During the ore washing process, the stirring device continuously stirs the ore to fully mix it with the washing water. Soil and impurities are separated from the ore surface and rise with the washing water to the overflow port 6. The muddy water flows out through the outlet 7 and flows into the receiving tank 13 along the inclined guide plate. In the receiving tank 13, the filter screen 14 performs preliminary filtration of the muddy water. Larger particles and some fine ore particles are intercepted on the surface of the filter screen 14. The material intercepted by the filter screen 14 is cleaned regularly and collected for further processing and recycling. The filtered water is discharged from the drain of the receiving tank 13 and enters the external sewage treatment system or the circulating water system to achieve the rational utilization of water resources.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
