Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, and in particular to a wastewater heavy metal treatment device with magnetic adsorption function. Background Technology

[0002] A search revealed that existing technologies mostly employ a single filtration system to directly treat wastewater, lacking specialized separation methods for magnetic metal impurities. This results in metal particles easily remaining on the filter screen or in the wastewater, making effective recovery impossible. Furthermore, relying solely on the filter screen to trap impurities without distinguishing between magnetic and non-magnetic impurities leads to the mixing and accumulation of metal particles and non-metallic impurities, reducing filtration efficiency and increasing the difficulty of subsequent treatment. To address these issues, this technical solution provides a wastewater heavy metal treatment device with magnetic adsorption function. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 4In this embodiment of the present invention, a wastewater heavy metal treatment device with magnetic adsorption function includes: a main body 1, an inlet hopper 2 fixedly connected to the top of the main body 1 and communicating with the inner side of the main body 1, a partition plate 3 fixedly connected to the inner side of the main body 1, a collection drawer groove 4 extending through to the inner side of the main body 1 on the outer side of the main body 1, a metal collection drawer 5 slidably connected to the inner side of the collection drawer groove 4, a wastewater outlet 6 extending through to the inner side of the main body 1 on the outer side of the main body 1, the collection drawer groove 4 and the wastewater outlet 6 being located at both ends of the partition plate 3 respectively, the bottom of the wastewater outlet 6 being a sloping groove design to facilitate wastewater discharge, a filter screen drawer groove 14 extending through to the inner side of the main body 1, a filter screen drawer 7 slidably connected to the inner side of the filter screen drawer groove 14, a filter screen of selectable mesh size below the filter screen drawer 7, and the filter screen drawer 7 being completely... When fully retracted, it is located above the wastewater outlet 6. When the filter drawer 7 is fully retracted, it can be limited by the screw threaded to the outside of the main body 1. A long guide rod 8 is fixedly connected between the inside of the main body 1 and the partition plate 3. A long threaded rod 9 is rotatably connected between the inside of the main body 1 and the partition plate 3. A fixed horizontal plate 10 is provided on the inside of the main body 1. An anti-clogging hard brush 11 is fixedly connected below the fixed horizontal plate 10. A guide hole adapted to the long guide rod 8 is opened on the outside of the fixed horizontal plate 10. A threaded hole adapted to the long threaded rod 9 is opened on the outside of the fixed horizontal plate 10. The anti-clogging hard brush 11 is in close contact with the filter screen inside the filter drawer 7. A first motor 12 is fixedly connected to the outside of the main body 1. The rotating shaft of the first motor 12 passes through the main body 1 and is fixedly connected to the long threaded rod 9. A magnetic impurity screening mechanism 13 is provided on the inside of the main body 1.

[0023] After the wastewater enters the main tank 1 through the inlet hopper 2, it first passes through the filter screen drawer 7 to filter large particles of impurities. When the filter screen becomes clogged, the first motor 12 drives the long threaded rod 9 to rotate, which in turn moves the fixed horizontal plate 10 along the long guide rod 8, causing the anti-clogging hard brush 11 to scrape off the blockage on the surface of the filter screen. The filtered wastewater flows into the area of ​​the magnetic impurity screening mechanism 13, where magnetic metal impurities are adsorbed onto the surface of the outer conveyor belt 134, while non-magnetic impurities are discharged with the water flow through the wastewater outlet 6. After the metal impurities are demagnetized by the non-magnetic support roller 132, they fall into the metal collection drawer 5, completing the metal recovery.

[0024] The magnetic impurity screening mechanism 13 includes a drive roller 131. Several sets of non-magnetic support rollers 132 and magnetic support rollers 133 are arranged on the side of the drive roller 131. The non-magnetic support rollers 132 are located above the collection drawer groove 4, and the magnetic support rollers 133 are located above the wastewater discharge outlet 6. An outer conveyor belt 134 is arranged on the outside of the drive roller 131, the non-magnetic support rollers 132 and the magnetic support rollers 133. A pusher plate 135 is uniformly fixedly connected to the outside of the outer conveyor belt 134. A second motor 136 is fixedly connected to the outside of the main box 1. The drive shaft of the second motor 136 passes through the main box 1 and is fixedly connected to the drive roller 131.

[0025] The second motor 136 drives the drive roller 131 to drive the outer conveyor belt 134 to rotate in a cycle. The magnetic support roller 133 generates a magnetic field to attract metal impurities in the wastewater to the surface of the outer conveyor belt 134. When the pusher plate 135 moves with the belt, it moves the metal impurities clockwise along the surface of the outer conveyor belt 134. When the belt runs to the area of ​​the non-magnetic support roller 132, the magnetic force disappears and the metal impurities fall off into the metal collection drawer 5 under the action of gravity. The non-magnetic impurities are pushed by the water flow to bypass the outer conveyor belt 134 and are discharged through the inclined channel of the wastewater outlet 6.

[0026] Its characteristic is that when the filter drawer 7 is fully retracted, it can be limited by a screw threaded to the outside of the main body 1;

[0027] When the filter needs to be cleaned or replaced, loosen the limiting screw on the outside of the main housing 1 and pull out the filter drawer 7 completely along the filter drawer groove 14. When the filter is in operation, the limiting screw presses the filter drawer 7 tightly through the thread to ensure that the filter is sealed and fitted to the inner wall of the main housing 1.

[0028] The working principle of this utility model is as follows: After the wastewater enters the main tank 1 through the inlet hopper 2, it first flows past the outer side of the outer conveyor belt 134 of the magnetic impurity screening mechanism 13. The magnetic support roller 133 generates a magnetic field, which adsorbs the metal impurities in the wastewater onto the surface of the belt. The pusher plate 135 pushes the adsorbed metal impurities to move with the belt. When the belt runs to the area of ​​the non-magnetic support roller 132, the magnetic force disappears, and the metal impurities fall into the metal collection drawer 5.

[0029] After magnetic treatment, the wastewater, carrying residual non-magnetic impurities, slides down the inner wall of the main tank 1 to the top of the filter screen drawer 7. The filter screen, based on its mesh size, traps large particles of non-magnetic impurities remaining in the wastewater, preventing them from entering the discharge stage.

[0030] When impurities accumulate on the filter screen surface, the first motor 12 drives the long threaded rod 9 to rotate, which in turn drives the fixed horizontal plate 10 to move along the long guide rod 8. The anti-clogging hard brush 11 scrapes the filter screen back and forth to remove blockages and ensure filtration efficiency.

[0031] The filtered wastewater is discharged through the inclined channel of wastewater outlet 6. The inclined channel is designed to accelerate the discharge by gravity. When the filter screen needs to be cleaned, loosen the limiting screw and pull out the filter screen drawer 7 along the filter screen drawer groove 14. After cleaning, reset and tighten the screw to ensure sealing.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
