Description

Technical Field

[0001] This utility model relates to the field of mineral processing wastewater treatment technology, specifically to a mineral processing wastewater treatment device. Background Technology

[0002] During mining and mineral processing, a large amount of wastewater is generated. This wastewater contains not only pollutants but also incompletely extracted valuable metal ions, such as copper, zinc, and iron, as well as recyclable water resources. If this wastewater is not treated, on the one hand, the unrecovered valuable metals are discharged with the wastewater, wasting mineral resources and polluting the environment; on the other hand, the direct discharge of large amounts of untreated water not only fails to achieve water recycling but also exacerbates the water shortage situation in the mining area and surrounding regions. Therefore, it is necessary to treat this wastewater using mineral processing wastewater treatment equipment.

[0003] In the prior art, utility model patent with patent number CN201721300685.7 discloses a mining wastewater treatment device, including a purification treatment body and a sedimentation purification device.

A sliding abutment rod is rotatably arranged on the outer side of the fan-shaped grids. The sliding rod device is provided with a matching opening curved rod and a retracting curved rod along the rotation path of the sliding abutment rod.

[0007] Preferably, the sliding abutment rod abuts against the outer side of the opening curved rod as the grid disc rotates; the corresponding fan-shaped grid gradually slides out of the grid disc as the opening curved rod is pulled.

[0008] Preferably, the sliding abutment rod that abuts against the opening curved rod is disposed on the inner side of the retracting curved rod after disengaging from the opening curved rod; the corresponding fan-shaped grid gradually retracts into the grid plate along with the retracting curved rod.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a mineral processing wastewater treatment device includes a bar screen and a conveying pipe 2, as well as a sliding rod device 5. The bar screen is an annular bar screen 1, which includes a horizontally rotating bar screen 7. Multiple outwardly opening fan-shaped bar screens 703 are sequentially arranged along the circumference of the bar screen 7. A wastewater treatment tank 3 and a waste bin 4 are arranged below the bar screen 7. The conveying pipe 2 is located above the bar screen 7, corresponding to the position of the wastewater treatment tank 3. A support column 6 is also included, with the bar screen 7 rotatably mounted on its upper end. The bar screen 7 includes a rotating groove 706, which is formed in the middle of the lower end face of the bar screen 7 and is rotatably mounted on the upper end of the support column 6. The support column 6 includes a motor housing 601, which houses a drive motor. The output shaft of the drive motor extends to the outside of the motor housing 601 and is equipped with a first bevel gear 602. A second bevel gear 707 is located on the lower end face of the bar screen 7, and the first bevel gear 602 and the second bevel gear 707 mesh with each other. The bar screen 7 is rotatably mounted on the support column 6 and is driven by a drive motor to rotate at a speed of 0.1 m / s. This ensures that the fan-shaped bar screen 703 will not be thrown out during the rotation. When the ore wastewater is transported to the wastewater treatment tank 3 through the conveying pipe 2, it will be filtered through the fan-shaped bar screen 703 on the bar screen 7 to prevent large pieces of waste from continuing to the next process.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, a sliding abutment rod 704 is rotatably provided on the outer side of the fan-shaped grille 703. A matching opening curved rod 501 and a retracting curved rod 502 are provided on the sliding rod device 5 along the rotation path of the sliding abutment rod 704. The sliding abutment rod 704 abuts against the outer side of the opening curved rod 501 as the grille disk 7 rotates; the corresponding fan-shaped grille 703 gradually slides out of the grille disk 7 along with the opening curved rod 501. After the sliding abutment rod 704 abuts against the opening curved rod 501, it abuts against the inner side of the retracting curved rod 502; the corresponding fan-shaped grille 703 gradually retracts back into the grille disk 7 along with the retracting curved rod 502. The grille disk 7 has multiple grille mounting cavities 701, each compatible with the fan-shaped grille 703, arranged sequentially along its circumference. The fan-shaped grille 703 is slidably installed in the grille mounting cavity 701. The fan-shaped grille 703 includes grille rails 705, with multiple grille rails 705 arranged parallel to each other. Guide holes 702 are provided on the outer ring side of the grille disk 7 corresponding to the positions of several grille rails 705. The fan-shaped grille 703 is slidably mounted in the grille mounting cavity 701 through the guide holes 702. Multiple grille rails 705 are arranged parallel to the moving direction of the fan-shaped grille 703. The guide holes 702 are located at the positions of the three grille rails 705 in the middle position, which can prevent the fan-shaped grille 703 from detaching and also prevent it from shifting when pulled out. As the grid disc 7 rotates, the fan-shaped grid 703, which has moved to the position of the open curved rod 501, will abut against the outer side of the open curved rod 501 through the sliding abutment rod 704. The outer side of the sliding abutment rod 704 is fitted with a rotating sleeve, so that the sliding abutment rod 704 can slide against the open curved rod 501. The curve of the open curved rod 501, after measurement, can drive the fan-shaped grid 703 to gradually pull out of the grid mounting cavity 701 of the grid disc 7, so that the garbage on the fan-shaped grid 703 can be leaked from the grid mounting cavity 701 into the garbage bin 4. When the fan-shaped grid 703 is pulled out to its maximum extent, it will gradually retract back into the grid mounting cavity 701 through the retracting curved rod 502 for filtering mineral processing wastewater.

[0029] Example 2

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a mineral processing wastewater treatment device includes a bar screen and a conveying pipe 2, as well as a sliding rod device 5. The bar screen is an annular bar screen 1, which includes a horizontally rotating bar screen 7. Multiple outwardly opening fan-shaped bar screens 703 are sequentially arranged along the circumference of the bar screen 7. A wastewater treatment tank 3 and a waste bin 4 are arranged below the bar screen 7. The conveying pipe 2 is located above the bar screen 7, corresponding to the position of the wastewater treatment tank 3. A support column 6 is also included, with the bar screen 7 rotatably mounted on its upper end. The bar screen 7 includes a rotating groove 706, which is formed in the middle of the lower end face of the bar screen 7 and is rotatably mounted on the upper end of the support column 6. The support column 6 includes a motor housing 601, which houses a drive motor. The output shaft of the drive motor extends to the outside of the motor housing 601 and is equipped with a first bevel gear 602. A second bevel gear 707 is located on the lower end face of the bar screen 7, and the first bevel gear 602 and the second bevel gear 707 mesh with each other.

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, a sliding abutment rod 704 is rotatably provided on the outer side of the fan-shaped grille 703. A matching opening curved rod 501 and a retracting curved rod 502 are provided on the sliding rod device 5 along the rotation path of the sliding abutment rod 704. The sliding abutment rod 704 abuts against the outer side of the opening curved rod 501 as the grille disk 7 rotates; the corresponding fan-shaped grille 703 gradually slides out of the grille disk 7 along with the opening curved rod 501. After the sliding abutment rod 704 abuts against the opening curved rod 501, it abuts against the inner side of the retracting curved rod 502; the corresponding fan-shaped grille 703 gradually retracts back into the grille disk 7 along with the retracting curved rod 502. The grille disk 7 has multiple grille mounting cavities 701, each compatible with the fan-shaped grille 703, arranged sequentially along its circumference. The fan-shaped grille 703 is slidably installed in the grille mounting cavity 701. The fan-shaped grille 703 includes grille railings 705, and multiple grille railings 705 are arranged in parallel at intervals in the fan-shaped grille 703; guide holes 702 are provided on the outer ring side of the grille disk 7 corresponding to the positions of several of the grille railings 705, and the fan-shaped grille 703 is slidably disposed in the grille mounting cavity 701 through the guide holes 702.

[0032] The working principle of this utility model is as follows: When in use, the bar screen 7 is driven by a drive motor to rotate. When the mineral processing wastewater is transported to the wastewater treatment tank 3 through the material conveying pipe 2, it will be filtered through the fan-shaped bar screen 703 on the bar screen 7 to prevent large pieces of waste from continuing to the next process. As the grid disc 7 rotates, the fan-shaped grid 703, which has moved to the position of the open curved rod 501, will abut against the outer side of the open curved rod 501 through the sliding abutment rod 704. The outer side of the sliding abutment rod 704 is fitted with a rotating sleeve, so that the sliding abutment rod 704 can slide against the open curved rod 501. The curve of the open curved rod 501, after measurement, can drive the fan-shaped grid 703 to gradually pull out of the grid mounting cavity 701 of the grid disc 7, so that the garbage on the fan-shaped grid 703 can be leaked from the grid mounting cavity 701 into the garbage bin 4. When the fan-shaped grid 703 is pulled out to its maximum extent, it will gradually retract back into the grid mounting cavity 701 through the retracting curved rod 502 for filtering mineral processing wastewater.

[0033] In summary, this utility model, by setting a rotatable grid plate 7 and arranging multiple pull-out fan-shaped grids 703 around the grid plate 7, can control the fan-shaped grids 703 to automatically open and retract when passing the opening curved rod 501 and the retracting curved rod 502, thereby achieving automatic cleaning of the waste in the fan-shaped grids 703 and improving the cleaning efficiency of mineral processing wastewater; by setting a motor box 601 on the side of the support column 6, the internal drive motor can be protected to avoid damage from moisture.

[0034] 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.
