Description

Technical Field

[0001] The present invention relates to the field of recovery devices, in particular to an industrial wastewater metal recovery device and a treatment method. Background Art

[0002] Industrial wastewater contains a large amount of heavy metals. If the wastewater is discharged directly without treatment, it will cause environmental pollution. In order to reduce the degree of environmental pollution, the heavy metals in the wastewater need to be treated and recovered. Usually, chemical mixing is used to separate the heavy metals in the wastewater, and then the heavy metals in the wastewater are precipitated and recovered. The existing wastewater heavy metal recovery device, when in use, directly adds the wastewater and the separation liquid into the reactor, and then uses a stirring element to stir the wastewater and the separation liquid so that the wastewater and the separation liquid are fully mixed, and the separation liquid can separate the heavy metals in the wastewater.

[0003] However, industrial wastewater often contains a large number of metal bacteria. Since the inside of the reactor is difficult to clean manually, the bacteria attach to the inner wall of the reactor and the stirring rod and gradually grow. If it is not cleaned for a long time, excessive impurities will easily cause the inner wall of the reactor to corrode, affecting the service life of the reactor. Summary of the 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.

The filter layer 30 divides the interior of the reactor 1 into a processing chamber 6 and a filter chamber 7. The wastewater mixing and stirring mechanism can accelerate the separation of wastewater in the reactor 1 and prevent the sedimentation of wastewater from accumulating at the bottom of the processing chamber 6 during the separation period, resulting in insufficient separation of metals. The wastewater mixing and stirring mechanism is located at the inner center of the processing chamber 6; the maintenance mechanism can maintain the wastewater mixing and stirring mechanism. The protection mechanism is located on the inner wall of one side of the processing chamber 6. The wastewater mixing and stirring mechanism includes a motor 31, a shaft 5, a connecting block 8, a connecting rod 9, and a stirring plate 10. The motor 31 is fixedly installed on the top outer wall of the reactor 1. The top outer wall of the reactor 1 is provided with a connecting hole connected to the processing chamber 6. The shaft 5 is arranged inside the processing chamber 6. The top outer wall of the shaft 5 passes through the connecting hole and is fixedly connected to the axis of the motor 31. There are two groups of connecting blocks 8. The outer wall of one end of the connecting block 8 is fixedly connected to the bottom outer wall of the shaft 5, and the outer wall of one end of the connecting rod 9 is fixedly connected to the outer wall of one end of the connecting block 8. The outer wall of the end of the connecting rod 9 away from the connecting block 8 is fixedly connected to the outer wall of one side of the stirring plate 10. A cleaning gasket 11 is provided on the outer wall of one side of the stirring plate 10, and the outer wall of one side of the cleaning gasket 11 is movably connected to the inner wall of the processing chamber 6.

[0027] When wastewater and separation liquid are discharged into the reactor 1 through the input pipe 2 in the present invention, the staff drives the shaft 5 to rotate by starting the motor 31, and the shaft 5 drives the stirring plate 10 to rotate through the connecting rod 9.

In addition, by providing the cleaning gasket 11, the stirring plate 10 can scrape off the microorganisms and bacteria attached to the inner wall of the processing chamber 6 while rotating, thereby avoiding the continuous growth of bacteria.

[0029] On the basis of Example 1, the maintenance mechanism includes a slide rail 14, a slider 16, a connecting bearing 17, an extension rod 18, a Velcro 19, and a cleaning sponge 20. A placement groove is provided on one inner wall of the processing chamber 6, and the outer wall of the slide rail 14 is fixedly connected to the inner wall of the placement groove. A slide groove 15 is provided on the inner wall of the slide rail 14, and the outer wall of the slider 16 is slidably connected to the inner wall of the slide groove 15. Two connecting bearings 17 are provided, and the outer walls of one side of the two connecting bearings 17 are fixedly connected to the outer wall of one side of the slider 16.

The outer wall of the stirring plate 10 is provided with a tooth groove 13, and the outer wall of the gear 21 is meshed with the inner wall of the tooth groove 13.

[0030] The present invention utilizes the rotation of the stirring plate 10 to wipe off the bacteria attached to the outer wall of the stirring plate 10 by the cleaning sponge 20. Since the stirring plate 10 has an inclination, the slider 16 is provided so that when the stirring plate 10 passes, the two extension rods 18 can move along with the outer wall of the stirring plate 10, thereby wiping the outer wall of the stirring plate 10. By providing the gear 21 and the tooth groove 13, when the stirring plate 10 passes between the two extension rods 18, the meshing rotation of the gear 21 can drive the cleaning sponge 20 to rotate moderately, thereby avoiding excessive backlog and causing scratches on the stirring plate 10 by the cleaning sponge 20, thereby ensuring the service life of the stirring plate 10. The maintenance mechanism can keep the stirring plate 10 and the inner wall of the reactor 1 clean, reducing the cleaning workload of the staff. When the cleaning sponge 20 is used for too long and ages and needs to be replaced, the staff only needs to tear off the cleaning sponge 20 from the Velcro 19 to replace it, which is convenient for maintenance.

[0033] When the slider 16 moves to the top, the block 23 can be stuck in the slot 25 to prevent the slider 16 from falling after the stirring plate 10 is detached. When the block 23 enters the slot 25, the cleaning brush 27 will sweep away the metal that may be accumulated on the top of the block 23, and after the slot 25 is pressurized by the block 23, the waste water in the slot 25 will be discharged from the pressure outlet 26 to avoid pressure. By setting the inclined slope 22, metal particles that may fall in the chute 15 can be prevented from accumulating in the chute 15.

[0034] In actual use, when waste water and separation liquid are discharged into the reactor 1 through the input pipe 2 in the present invention, the staff drives the shaft 5 to rotate by starting the motor 31, and the shaft 5 drives the stirring plate 10 to rotate through the connecting rod 9. The rotation of the stirring plate 10 can drive the stirring of the waste water in the processing chamber 6, thereby preventing the sediment from accumulating at the bottom of the processing chamber 6 during the waste water separation period, resulting in insufficient separation of the metal. In addition, by providing a cleaning gasket 11, the stirring plate 10 can scrape off the microorganisms and bacteria attached to the inner wall of the processing chamber 6 while rotating, thereby preventing continuous breeding of bacteria. The present invention utilizes the rotation of the stirring plate 10 to wipe off the bacteria attached to the outer wall of the stirring plate 10. Since the stirring plate 10 has an inclination, the slider 16 can be provided so that the two extension rods 18 can move with the outer wall of the stirring plate 10 when the stirring plate 10 passes, thereby wiping the outer wall of the stirring plate 10. By providing the gear 21 and the tooth groove 13, the stirring plate 10 can be moved when passing through the two When the cleaning sponge 20 is used for too long and ages and needs to be replaced, the staff only needs to tear off the cleaning sponge 20 from the Velcro 19 to replace it, which is convenient for maintenance. When the slider 16 moves to the top, the block 23 can be stuck in the slot 25 to prevent the slider 16 from falling after the stirring plate 10 is separated. When the block 23 enters the slot 25, the cleaning brush 27 will sweep away the metal that may be accumulated on the top of the block 23, and after the slot 25 is backlogged by the block 23, the waste water in the slot 25 will be discharged from the pressure outlet 26 to avoid pressure. By setting the inclined slope 22, it is possible to prevent metal particles that may fall in the chute 15 from accumulating in the chute 15.
