In addition, the above scheme uses a motor to drive the stirring rod to rotate to achieve sufficient mixing of the magnetic powder and sewage, which has the disadvantages of high energy consumption and high cost.

[0027] An opening and closing door is provided on the liquid outlet 25, and the opening and closing door includes a rotating cover 30 movably connected to the bottom of the liquid outlet 25 and a rotating motor 26 fixedly connected to the rotating cover 30. The end of the output shaft of the rotating motor 26 is fixedly connected to the rotating cover 30 through a reducer, and the rotating motor 26 is fixedly connected to the bottom of the liquid outlet 25. The rotating motor 26 can drive the rotating cover 30 fixedly connected thereto to rotate, and the liquid outlet 25 can be opened and closed when the rotating cover 30 rotates.

[0028] The top end of the rotating tube 28 extends to the top of the turbine 4, and the outer ring of the top end of the rotating tube 28 is fixedly connected with a sprocket ring 29. The two adjacent sprocket rings 29 are connected by a transmission belt 33. Through the arrangement of the sprocket ring 29 and the transmission belt 33, the two adjacent rotating tubes 28 can influence each other, so that the rotating tube 28 in the device can always be in a rotating state.

[0029] The bottom end of the rotating tube 28 extends to the top of the inner cavity of the mixing box 3. The stirring rod 24 is evenly fixed to the bottom of the rotating tube 28. When the rotating tube 28 rotates, it can drive the stirring rod 24 fixedly connected thereto to rotate. A magnetic powder introduction tube 6 is movably connected to the inner cavity of the rotating tube 28. The magnetic powder introduction tube 6 is in a fixed connection with the turbine 4. The magnetic powder can enter the mixing box 3 through the magnetic powder introduction tube 6. After the magnetic powder enters the mixing box 3, the rotation of the stirring rod 24 can make the sewage and the magnetic powder evenly mixed, which is convenient for the flocculation of the sewage.

[0030] A connecting hole 27 is provided at the bottom of the mixing box 3, and the mixing box 3 is connected to the temporary storage box 2 through the connecting hole 27.

[0034] A plate chain separation belt is provided at the bottom end of the inner cavity of the separation box 1, and the plate chain separation belt includes a transmission chain 16, an electromagnetic plate 15 and a conductive rod 14. Both ends of the inner cavity of the separation box 1 are movably connected with a transmission roller 32, and the two transmission rollers 32 are transmission-connected through the transmission chain 16, and both ends of the transmission roller 32 are provided with a transmission chain 16. One end of the separation box 1 is fixedly connected with a transmission motor 9, and the end of the output shaft of the transmission motor 9 is fixedly connected to the end of a transmission roller 32 through a reducer. Through the setting of the transmission motor 9, the rotation of the transmission motor 9 can drive the transmission roller 32 fixedly connected thereto to rotate, and the rotating transmission roller 32 can drive the transmission chain 16 to rotate.

[0035] The two transmission chains 16 are connected through the electromagnetic plate 15 and the telescopic net 35. The electromagnetic plate 15 is evenly provided with electromagnets. The end of the electromagnetic plate 15 is in an active connection with the transmission chain 16. The two adjacent electromagnetic plates 15 are connected through the telescopic net 35. The setting of the telescopic net 35 can avoid the contact between the magnetic particles and the side or back of the electromagnetic plate 15, which is convenient for cleaning the magnetic particles adhering to the electromagnetic plate 15. The telescopic net 35 can limit the electromagnetic plate 15, so that the electromagnetic plate 15 can maintain a horizontal state when moving between the two transmission rollers 32, which is convenient for the electromagnetic plate 15 to adsorb the magnetic particles.

[0036] A power supply cavity is provided on one side of the bottom end of the inner cavity of the separation box 1, and a transmission chain 16 is movably connected to the cavity wall of the power supply cavity. A conductive rod 14 is fixed to one end of the electromagnetic plate 15 close to the power supply cavity, and the other end of the conductive rod 14 extends into the power supply cavity. A conductive plate 13 is fixed to the top of the inner cavity of the power supply cavity. The other end of the conductive rod 14 located at the upper end of the transmission chain 16 is in contact with the conductive plate 13. A conductive wire 12 is fixed to one end of the conductive plate 13, and the other end of the conductive wire 12 extends to the outside of the separation box 1. Through the setting of the power supply cavity, when the conductive rod 14 is in contact with the conductive plate 13, the electromagnetic plate 15 can be in a power supply state, and when the conductive rod 14 is separated from the conductive plate 13, the electromagnetic plate 15 is in a power-off state, and the electromagnetic plate 15 located above the plate chain separation belt is in a power supply state, and the electromagnetic plate 15 located below the plate chain separation belt is in a power-off state.

[0037] The end of the connecting pipe 7 away from the temporary storage box 2 is located above the plate chain separation belt, and the evenly mixed sewage can contact the electromagnetic plate 15. The plate chain separation belt divides the inner cavity of the separation box 1 into a clean water cavity and a sedimentation cavity. An upper scraper 31 is fixed to the top of the inner cavity of the sedimentation cavity. The upper scraper 31 contacts the bottom of the plate chain separation belt. When the transmission chain 16 rotates, the transmission chain 16 can drive the electromagnetic plate 15 to rotate. The electromagnetic plate 15 located above the plate chain separation belt can adsorb magnetic particles. When the electromagnetic plate 15 adsorbed with magnetic particles moves to the bottom of the plate chain separation belt, the upper scraper 31 can scrape off the magnetic particles adhered to the electromagnetic plate 15, thereby improving the efficiency of separating the magnetic particles from the electromagnetic plate 15. In addition, during the removal process of the magnetic particles, the plate chain separation belt can still attract the magnetic particles, so that the separation structure can perform continuous operation, thereby improving the working efficiency of the device.

[0038] A sewage pipe 11 is provided on one side of the bottom end of the sedimentation chamber, and a telescopic scraper is connected to the other end of the bottom end of the sedimentation chamber through a hydraulic telescopic rod 10. The telescopic scraper includes a moving plate 21 fixedly connected to the output end of the hydraulic telescopic rod 10. The moving plate 21 is located below the upper scraper 31. The bottom of the moving plate 21 is connected to a lower scraper 22 through a guide rod and a spring 19. Electromagnets 20 are fixed on one side of the lower scraper 22 close to the moving plate 21 and on the bottom of the moving plate 21. Through the setting of the electromagnet 20, currents in the same direction are passed through the two electromagnets 20. When the current flows, the two electromagnets 20 may be in a state of magnetic attraction. Under the action of the suction force, the lower scraper 22 may move upward, so that the bottom of the lower scraper 22 is separated from the bottom of the inner cavity of the sedimentation chamber, so as to facilitate the resetting of the telescopic scraper. When the electromagnet 20 is in a power-off state, under the action of the rebound force of the spring 19, the lower scraper 22 may fit tightly with the bottom of the inner cavity of the sedimentation chamber. At this time, when the telescopic scraper moves under the action of the hydraulic telescopic rod 10, the telescopic scraper may push the sediment gathered in the sedimentation chamber to move, so as to facilitate the discharge of the sediment through the sewage pipe 11.

[0039] The inner cavity of the clean water chamber is fixed with a limiting plate 17 and a limiting plate 2 18 in sequence, and a clean water pipe 8 is arranged on one side of the top of the clean water chamber. The limiting plate 17 and the limiting plate 2 18 are both inclined, and the clean water pipe 8 is located at the high end of the limiting plate 2 18, and the high end of the limiting plate 1 17 is located below the low end of the limiting plate 2 18, and the connecting pipe 7 is located below the high end of the limiting plate 1 17. The setting of the limiting plate 1 17 and the limiting plate 2 18 can slow down the flow speed of the sewage in the separation box 1, and facilitate the precipitation of the flocculants in the separation box 1, and the precipitates precipitated on the limiting plate 1 17 and the limiting plate 2 18 can be separated from the limiting plate 1 17 and the limiting plate 2 18 under the action of gravity. The outer surfaces of the limiting plate 1 17, the limiting plate 2 18 and the plate chain separation belt are all coated with an anti-stick coating, and the material of the anti-stick coating can be polytetrafluoroethylene.

[0040] In some embodiments of the present application, the electromagnet 20 and the electromagnet loaded in the electromagnetic plate 15 are both of model XDA-50 / 42.

[0041] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0042] In summary: when the magnetic separation water treatment device is used, magnetic powder is injected into the mixing box 3 through the magnetic powder introduction pipe 6, and sewage is injected into the turbine 4 through the sewage delivery pipe 5. After the sewage enters the turbine 4, the sewage pushes the turbine blades 23 to rotate, and the turbine blades 23 drive the rotating tube 28 fixedly connected thereto to rotate, and the rotating tube 28 drives the stirring rod 24 fixedly connected thereto to rotate, and the sewage enters the mixing box 3 through the liquid outlet 25. The rotation of the stirring rod 24 allows the sewage and the magnetic powder to be evenly mixed. After the amount of sewage injected into the mixing box 3 is appropriate, the liquid outlet 25 is in a closed state. The sewage and magnetic powder are fully mixed in the mixing box 3. After the sewage is mixed, the connecting hole 27 is in an open state, and the mixed liquid enters the separation box 1 through the connecting pipe 7. The electromagnetic plate 15 attracts the magnetic particles to achieve solid-liquid separation of the sewage. The separated liquid is discharged through the clean water pipe 8. When the magnetic particles magnetically attracted to the electromagnetic plate 15 move to the bottom of the plate chain separation belt along with the electromagnetic plate 15, the magnetic particles can be separated from the electromagnetic plate 15 under the action of gravity, and the magnetic particles remaining on the electromagnetic plate 15 can be scraped off by the upper scraper 31, and the precipitated impurities can be discharged through the sewage pipe 11.
