[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a phosphate ore dressing return water treatment device capable of realizing comprehensive utilization of water resources. Background Art

[0002] Phosphate rock refers to an important chemical mineral raw material. Phosphate rock can be used to produce phosphate fertilizer, yellow phosphorus, phosphoric acid, phosphide and other phosphates. Wastewater is generated during the screening process of phosphate rock, and it is necessary to operate the phosphate rock beneficiation return water treatment device to purify the wastewater, thereby realizing the comprehensive recycling of water resources and achieving the purpose of saving water resources. The structural components of the phosphate rock beneficiation return water treatment device include: frame, processing frame, feed hopper, motor, stirring rod, drain pipe and slag discharge pipe, etc.

[0003] After searching, a patent document with patent announcement number CN213202590U discloses a phosphate ore beneficiation return water treatment device that can realize comprehensive utilization of water resources. The device comprises a device body, a rotating shaft is provided inside the device body, a stirring rod is provided outside the rotating shaft, a capture spring is provided inside the stirring rod, a servo motor is provided at the top of one of the rotating shafts, a wedge plate is provided at the bottom of the rotating shaft, a discharge hopper is provided at the bottom of the wedge plate, a return pipe is provided at the bottom of the discharge hopper, and one side of the return pipe is movably connected to the outer wall of one side of the device body. Through the arrangement of the capture spring and the return pipe, the servo motor operates so that the capture spring inside the stirring rod can capture and collect impurities in the wastewater, thereby making the impurities in the wastewater can be well collected, and the wastewater after preliminary treatment can flow back to the device body through the return pipe, thereby making the wastewater further treated and better recycled.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing phosphate ore beneficiation return water treatment device, during use, the phosphate ore beneficiation return water is introduced into the interior of the treatment frame through a provided feed hopper, the servo motor is started to rotate the stirring rod, and the capture spring inside the stirring rod processes impurities in the wastewater to achieve wastewater treatment. However, it is inconvenient to use wastewater to rinse the debris on the capture spring and the stirring rod, and the remaining debris will adversely affect the treatment of the next batch of return water, thereby reducing the treatment quality of the phosphate ore beneficiation return water and the functionality of the existing phosphate ore beneficiation return water treatment device.

[0006] 2. In the existing phosphate ore beneficiation return water treatment device, during use, the servo motor is started to drive the stirring rod to rotate, and then the capture spring is rotated to clean the debris in the wastewater, thereby achieving wastewater purification.
