The specific contents are as follows; 1. A stirring shaft, a baffle and a stirring blade are provided. 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 the pretreatment of the wastewater. 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.

[0015] 2. An electromagnetic sieve plate, a rotating plate and a friction plate are provided.

As the rotating drum rotates, the rotating plate will drive the friction plate to rotate, so that 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 from the electromagnetic sieve plate, so that the metal waste generates magnetic force due to the reciprocating friction, which is convenient for the waste generated by the magnetic force to adsorb 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.

As the rotating drum rotates, when the electromagnetic sieve plate moves to the highest point, the rotating plate rotates and resets, and the terminal on the outside of the electromagnetic sieve plate separates from the conductive electrode sheet, causing the electromagnetic sieve 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, so that the metal scraps on the outside of the electromagnetic sieve plate will automatically fall into the cavity of the rotating drum. Subsequently, the metal scraps will be regularly cleaned and collected by opening the cover plate and the discharge door. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 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; 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, and a solenoid valve tube is connected between the lower tank body 1 and the upper tank body 2, and a motor 3 is fixedly installed on the upper end of the upper tank body 2, and a stirring shaft 4 is fixedly installed on the output end of the motor 3; 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. A magnetic strip 14 and a second magnetic block 19 are also fixedly installed on the inner wall of the lower tank body 1, and a magnetic drive component for controlling the rotating plate 10 to rotate and adjust 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 shaft 4, and the baffle 401 fits the outer side of the stirring blade 5 to limit the rotation angle of the stirring blade 5.

[0021] An arc-shaped conductive electrode sheet 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 sheet 601 to realize the power connection of the electromagnetic sieve plate 8. The gap between the two ends of the conductive electrode sheet 601 faces upward, and when the terminal head 801 moves to the gap between the two ends of the conductive electrode sheet 601, the electromagnetic sieve plate 8 is automatically powered off.

[0022] 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 the metal scraps mixed in the wastewater.

[0023] 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 the first magnetic block 16 passes through the outside of the magnetic strip 14 during the rotation of the electromagnetic screen plate 8. 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 through the outside of the magnetic strip 14, it moves closer to the magnetic strip 14 under the action of magnetic force.

[0024] The magnetic drive assembly also includes a gear 18 rotatably mounted on the outer side of the shaft of the rotating plate 10, and a rack 17 is fixedly connected to the outer side of the slide bar 15, and the rack 17 is meshed with the gear 18 during the movement of the slide bar 15 to drive the rotating plate 10 to rotate elastically.

[0025] 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 outer side 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.

[0026] 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 against 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 outer side of the electromagnetic sieve plate 8. During the reciprocating movement of the friction plate 11, the metal waste adsorbed on the top of the electromagnetic sieve plate 8 is rubbed.

[0027] By adopting the above technical solution, heavy metal wastewater is injected into the upper tank body 2 through a 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 causes 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 lower end center position of the upper tank body 2 under the action of the vortex. At this time, the solenoid valve tube 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 sheet 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 bar 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 Close to the electromagnetic sieve plate 8, at this time, the friction plate 11 is 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.

[0028] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing heavy metal processing wastewater treatment machine is inconvenient to automatically clean and collect 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 Fig. 9 As shown; the outer wall of the rotating cylinder 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 end opening of the rotating cylinder 7, and a cavity structure is provided on the inner side of the rotating cylinder 7, and a third magnetic block 22 is fixedly installed on the outer side of the movable plate 20 through a bracket 21. At the same time, during the rotation of the rotating cylinder 7, the third magnetic block 22 is driven to move to the outer side of the second magnetic block 19, and the second magnetic block 19 and the third magnetic block 22 have opposite magnetic poles on the opposite surfaces, and the movable plate 20 is elastically rotated under the action of both the second magnetic block 19 and the third magnetic block 22.

[0029] By adopting the above technical solution, when the electromagnetic sieve 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, and at the same time, the terminal 801 of the electromagnetic sieve plate 8 will slide away from the conductive electrode sheet 601, so that the electromagnetic sieve 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 sieve plate 8 can enter the interior of the rotating cylinder 7, and 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 centrally cleaned.
