[0002] During the heavy metal processing process, a large amount of industrial wastewater is often generated. This wastewater contains a large amount of heavy metal debris. Direct discharge will cause serious environmental pollution and waste of metal resources. Therefore, a wastewater treatment machine is needed to purify the wastewater.

[0003] Prior art (Chinese Patent Application No. 202320348766.3, filed on February 28, 2023) discloses a reclaimed water treatment device comprising a wastewater treatment tank and supporting columns. The supporting columns are mounted on the outer surface of the wastewater treatment tank, and a discharge pipe is mounted on the bottom surface of the wastewater treatment tank.

The baffle is positioned within the tank, and the baffle is provided with filter holes and an operating slot. A filter layer and a magnetic plate are mounted within the tank, with the magnetic plate positioned between the baffles and a handle on the top surface.

The specific contents are as follows;

[0016] 1. It is equipped with a stirring shaft, a baffle and a stirring blade. With the drive of the motor, the stirring shaft drives multiple stirring blades to rotate synchronously, so that the stirring blades stir the sewage in the upper tank body to achieve wastewater pretreatment. At this time, the wastewater in the upper tank body will generate a vortex, so that the metal scraps in the wastewater will gather to the middle position of the bottom of the upper tank body, and then can be concentrated and accurately discharged to the electromagnetic sieve plate through the electromagnetic valve pipe.

As the rotating drum rotates, the rotating plate will drive the friction plate to rotate, and then the friction plate cooperates with the electromagnetic sieve plate to clamp the metal waste. Subsequently, as the rotating plate slides back and forth, the friction plate can rub the metal waste filtered out of the electromagnetic sieve plate, so that the metal waste generates magnetic force due to the reciprocating friction, which facilitates the subsequent magnetic waste to attract each other, so as to improve the convenience of subsequent cleaning and collection. In addition, the metal waste can achieve an effective drying effect during the rotation and friction process, which further improves the convenience of subsequent collection of the waste.

[0018] 3. A second magnetic block and a movable plate are provided. As the rotating drum rotates, when the electromagnetic screen plate moves to the highest point, the rotating plate rotates and resets, and the terminal on the outside of the electromagnetic screen plate separates from the conductive electrode, causing the electromagnetic screen plate to lose its magnetic effect. At the same time, the movable plate will elastically rotate under the magnetic force of the second and third magnetic blocks, thereby causing the metal scraps on the outside of the electromagnetic screen plate to automatically fall into the cavity of the rotating drum. Subsequently, the metal scraps are regularly cleaned and collected by opening the cover plate and the discharge door. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 As shown, the existing heavy metal processing wastewater treatment machine is inconvenient to automatically adsorb and filter the metal scraps in the wastewater during use, resulting in a low recovery rate of the metal scraps in the wastewater. In order to solve this technical problem, this embodiment discloses the following technical content;

[0031] A magnetic chip removal type heavy metal processing wastewater treatment machine comprises a lower tank body 1 and an upper tank body 2 which are fixedly connected, wherein a solenoid valve tube is connected between the lower tank body 1 and the upper tank body 2, and a motor 3 is fixedly mounted on the upper end of the upper tank body 2, and a stirring shaft 4 is fixedly mounted on the output end of the motor 3;

[0032] A fixed column 6 is fixedly installed on the inner side of the lower tank body 1, and a rotating cylinder 7 is rotatably sleeved on the outer side of the fixed column 6, and an electromagnetic sieve plate 8 is evenly fixedly installed on the outer side of the rotating cylinder 7, and a guide column 9 is symmetrically slidably installed on the outer side of the electromagnetic sieve plate 8, and a rotating plate 10 is rotatably installed on the outer side of the guide column 9, and a friction plate 11 is elastically connected to the outer side of the rotating plate 10. The inner wall of the lower tank body 1 is also fixedly installed with a magnetic strip 14 and a second magnetic block 19, and a magnetic drive component for controlling the rotation adjustment of the rotating plate 10 is connected between the guide column 9 on one side and the rotating plate 10; a stirring blade 5 is evenly and elastically rotatably installed on the outer side of the stirring shaft 4, and a baffle 401 is evenly installed on the outer side of the stirring blade 5, and the baffle 401 fits the outer side of the stirring blade 5 to limit the rotation angle of the stirring blade 5.

[0033] An arc-shaped conductive electrode 601 is embedded in the outer wall of the rear end of the fixed column 6, and a terminal head 801 is fixedly installed on the outer side of the electromagnetic sieve plate 8. The terminal head 801 passes through the rotating cylinder 7 and slides against the conductive electrode 601 to realize the power connection of the electromagnetic sieve plate 8. The gap between the two ends of the conductive electrode 601 faces upward. At the same time, when the terminal head 801 moves to the gap between the two ends of the conductive electrode 601, the electromagnetic sieve plate 8 is automatically powered off.

[0034] The electromagnetic valve tube and the electromagnetic sieve plate 8 are arranged in corresponding positions up and down, and the electromagnetic sieve plate 8 filters the sewage discharged from the electromagnetic valve tube, and the electromagnetic sieve plate 8 magnetically absorbs metal scraps mixed in the wastewater.

[0035] The magnetic drive assembly includes a slide rod 15 telescopically mounted on the guide column 9, and a first magnetic block 16 is fixedly mounted on the end of the slide rod 15, and the magnetic strip 14 is arranged in an arc-shaped structure, and during the rotation of the electromagnetic screen plate 8, the first magnetic block 16 passes through the outside of the magnetic strip 14, and at the same time, the magnetic poles of the opposite surfaces of the magnetic strip 14 and the first magnetic block 16 are opposite. When the first magnetic block 16 rotates and passes the outside of the magnetic strip 14, it moves closer to the magnetic strip 14 under the action of magnetic force.

[0036] The magnetic drive assembly also includes a gear 18 rotatably mounted on the outside of the shaft of the rotating plate 10, and a rack 17 is fixedly connected to the outside of the slide rod 15, and the rack 17 is engaged with the gear 18 during the movement of the slide rod 15 to drive the rotating plate 10 to rotate elastically.

[0037] During the rotation of the rotating plate 10, the friction plate 11 cooperates with the electromagnetic screen plate 8 to press the filtered and adsorbed metal debris, and a positioning column 12 is telescopically installed on the rotating plate 10, and the positioning column 12 is fixedly installed on the outside of the friction plate 11. At the same time, a second spring 13 is connected between the rotating plate 10 and the friction plate 11.

[0038] A first spring 901 is connected between the guide column 9 located on the front side and the electromagnetic sieve plate 8, and a conical structure is provided at one end of the guide column 9 located on the rear side close to the rotating cylinder 7. Baffles 602 are evenly provided on the outer side of the rear end of the fixed column 6, and the conical structure at the end of the guide column 9 slides in contact with the baffle 602 during the rotation of the rotating cylinder 7 to drive the rotating plate 10 and the friction plate 11 to slide back and forth on the outside of the electromagnetic sieve plate 8. During the reciprocating movement of the friction plate 11, the metal scraps adsorbed above the electromagnetic sieve plate 8 are rubbed.

[0039] By adopting the above technical solution, heavy metal wastewater is injected into the upper tank body 2 through the pipeline, and the motor 3 is started to drive the stirring shaft 4 to rotate. At this time, the stirring shaft 4 will drive the stirring blade 5 to rotate under the limiting action of the baffle 401, so that the stirring blade 5 will cause the wastewater to generate a vortex during the stirring process. When the stirring shaft 4 stops rotating, the stirring blade 5 will elastically rotate under the action of the vortex water flow, ensuring that the metal impurities in the wastewater can be gathered at the center position of the lower end of the upper tank body 2 under the action of the vortex. At this time, the solenoid valve pipe is opened, so that the wastewater containing a large amount of metal waste is automatically discharged to the electromagnetic sieve plate 8. Since the terminal 801 of the electromagnetic sieve plate 8 is in contact with the conductive electrode 601, the electromagnetic sieve plate 8 can rotate under the impact of the water flow while magnetically adsorbing the metal waste falling on its outside. When the first magnetic block 16 moves to the outside of the magnetic strip 14, the slide rod 15 will drive the rack 17 and the gear 18 to engage and connect under the action of the magnetic force, thereby driving the rotating plate 10 to drive the friction plate 11 to rotate close to the electromagnetic sieve plate 8. Near the electromagnetic sieve plate 8, the friction plate 11 is now attached to the outside of the electromagnetic sieve plate 8 under the action of the elastic force of the second spring 13, and with the further rotation of the rotating cylinder 7, the cone structure at the end of the guide column 9 can slide along the surface of the baffle 602, thereby driving the rotating plate 10 and the friction plate 11 to move back and forth on the outside of the electromagnetic sieve plate 8, thereby realizing automatic friction magnetization of the waste chips adsorbed on the electromagnetic sieve plate 8, ensuring that the waste chips can be adsorbed and gathered after magnetization, thereby facilitating the subsequent centralized collection of metal waste chips, and at the same time, when rubbing the metal chips, the metal chips generate heat through rotation and friction, thereby realizing automatic drying.

[0040] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. The existing heavy metal processing wastewater treatment machine is not convenient for automatically cleaning and collecting the filtered metal debris, thereby reducing the treatment and purification efficiency of the equipment. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 5 and Figure 9 As shown, the outer wall of the rotating drum 7 is evenly provided with collecting holes, and a movable plate 20 is elastically rotatably installed in the collecting hole, and a discharge door 23 is sealed and installed on the front side of the lower tank body 1. A cover plate 701 is installed at the front opening of the rotating drum 7, and a cavity structure is provided on the inner side of the rotating drum 7. A third magnetic block 22 is fixedly installed on the outer side of the movable plate 20 via a bracket 21. At the same time, during the rotation of the rotating drum 7, the third magnetic block 22 is driven to move to the outer side of the second magnetic block 19. The magnetic poles of the opposing surfaces of the second magnetic block 19 and the third magnetic block 22 are opposite. The movable plate 20 elastically rotates under the action of both the second magnetic block 19 and the third magnetic block 22.

[0041] By adopting the above technical solution, when the electromagnetic screen plate 8 moves to the highest position, the first magnetic block 16 will move away from the magnetic strip 14, so that the rotating plate 10 drives the friction plate 11 to elastically rotate and reset. At the same time, the terminal 801 of the electromagnetic screen plate 8 will slide away from the conductive electrode 601, so that the electromagnetic screen plate 8 is automatically powered off, and the bracket 21 on the movable plate 20 will drive the third magnetic block 22 to approach the second magnetic block 19. At this time, the movable plate 20 will elastically rotate under the magnetic force of the second magnetic block 19 and the third magnetic block 22, so that the metal debris falling from the outside of the electromagnetic screen plate 8 can enter the interior of the rotating cylinder 7. Subsequently, by opening the cover plate 701 and the discharge door 23, the metal waste collected in the cavity of the rotating cylinder 7 can be cleaned up in a centralized manner.

[0042] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
