Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, and in particular to copper-containing waste liquid treatment equipment and a treatment method. Background Art

[0002] Copper-containing waste liquid is a waste liquid containing copper ions. It is produced in smelting, metal processing, machine manufacturing, organic synthesis and other industries. When discharging this copper-containing waste liquid, it is necessary to remove the copper ion impurities in it to avoid polluting the environment when the waste liquid is discharged.

[0003] The existing Chinese patent application with publication number CN116986699A discloses a copper-containing waste liquid treatment equipment and treatment method, including a kettle, a stirring assembly and a solid-liquid separation assembly. The kettle is arranged vertically, and the top of the kettle is provided with an inlet No. 1 and an inlet No. 2 for respectively injecting waste liquid and chemical treatment agent into the kettle. The stirring assembly is arranged in the upper half of the kettle, and the stirring assembly is used to fully stir the waste liquid and the chemical treatment agent. The solid-liquid separation assembly is arranged in the lower half of the kettle, and the solid-liquid separation assembly divides the internal space of the kettle into a mixing reaction zone and a collection zone distributed up and down. In this invention, the waste liquid and the chemical treatment agent are firstly injected into the kettle through the inlet No. 1 and the inlet No. 2 respectively. Then, the waste liquid and the chemical treatment agent are stirred evenly by the stirring assembly.

[0004] However, the copper waste liquid treatment equipment has the following defects when used specifically:

[0005] 1. When the existing copper waste liquid treatment equipment treats the copper ion impurities in the waste liquid, it generally adopts the method of stirring and mixing the precipitant and the waste liquid so that the copper ion impurities can become solid precipitates. However, in the traditional method, when the waste liquid and the precipitant are stirred, the stirring and mixing operation of the waste liquid is generally achieved by starting the stirring roller to rotate through a driving part (motor, etc.). At this time, when the stirring roller rotates, a vortex is generally formed only at the center of the equipment, which has a poor stirring and mixing effect on the waste liquid and the precipitant, and a long time is required for the stirring and precipitation operation, which has low efficiency in waste liquid treatment;

[0006] 2. When the existing copper waste liquid treatment equipment treats the waste liquid, the waste liquid generally contains a variety of impurities (not only copper ion impurities). At this time, other impurities in the waste liquid are generally separated by sedimentation. However, the impurities in the waste liquid will adhere or adsorb on the inner wall of the equipment during sedimentation, which will cause some impurities to be unable to be discharged during the subsequent emptying of the waste liquid, resulting in poor treatment and emptying of the waste liquid.

[0044] The present invention also provides a method for treating a copper-containing waste liquid treatment device comprising the copper-containing waste liquid treatment device, comprising the following steps:

[0045] S1. Precipitant pretreatment: When purifying the copper-containing waste liquid, the copper ions in the copper-containing waste liquid are converted into solid precipitates by using chemical reactions to produce precipitation, thereby achieving the removal of copper ions. At this time, the eccentric stirring component stirs the precipitant inside the pretreatment box to achieve the precipitant pretreatment operation;

[0046] S2, stirring of waste liquid and precipitant: when treating the copper-containing waste liquid, firstly, the copper-containing waste liquid is transferred to the interior of the waste liquid reactor, and the stirred precipitant is transferred to the interior of the waste liquid reactor through the discharge pipe. Then, the gear stirring component operates to stir and precipitate the copper-containing waste liquid and precipitant in the waste liquid reactor to produce corresponding copper ion solid precipitate;

[0047] S3, precipitate screening: after the copper-containing waste liquid and the precipitant are stirred and mixed, the copper ion solid precipitate and the waste liquid are screened by the precipitation screening component, so that the waste liquid from which the copper ions are removed flows to the bottom of the precipitation screening component, and the impurities in the waste liquid are deposited at the inner bottom of the waste liquid reactor;

[0048] S4. Emptying of deposited impurities and liquid: When emptying the liquid and deposited impurities at the bottom of the waste liquid reactor, first empty the liquid. Then, the gear stirring component drives the inner wall sweeping component to automatically sweep and scrape the deposited impurities adhering to the inner wall of the waste liquid reactor to prevent the deposited impurities from adhering to the inner wall of the waste liquid reactor.

[0049] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0050] 1. In the copper-containing waste liquid treatment equipment and treatment method, when the copper-containing waste liquid is treated, the drive motor can be started to operate, driving the movable turntable and multiple groups of stirring rollers connected thereto to operate, and driving the multiple groups of stirring rollers to move in a circular manner to achieve stirring and sedimentation operations. At the same time, when the movable turntable rotates, the internal epicyclic gear connected by the connecting shaft will engage on the outside of the intermediate gear, thereby driving the multiple groups of stirring rollers that move in a circular manner to rotate, generating multiple movable vortices, thereby improving the efficiency of stirring and sedimentation of waste liquid and precipitant. At the same time, when the movable turntable rotates, the drive gear that drives the movable turntable to operate will also rotate, and drive the multiple groups of stirring blades connected to the drive gear to rotate, stirring and pre-treating the precipitant inside the pretreatment box, reducing the saturation of the precipitant, and effectively avoiding the phenomenon of excessive local concentration of the precipitant;

[0051] 2. In the copper-containing waste liquid treatment equipment and treatment method, when the movable turntable rotates to drive the stirring roller to operate, its rotating force will synchronously drive the stirring auger connected to its bottom to rotate, driving the waste liquid and precipitant at the bottom to move to the top, ensuring that the waste liquid and precipitate can be fully stirred and precipitated. At the same time, when the stirring auger rotates, it will also drive the bottom rod, side connecting rod and sweeping plate connected to its bottom to rotate, automatically sweeping and scraping the waste liquid impurities that have completed copper ion precipitation and deposition, to prevent the deposited waste liquid impurities from sticking or accumulating inside the waste liquid reactor;

[0052] 3. In the copper-containing waste liquid treatment equipment and treatment method, the copper ion fixed precipitate and waste liquid that are stirred and precipitated can be separated by a screening net to ensure that the copper ion fixed precipitate can remain on the top of the screening net, and the waste liquid can be transmitted to the inner bottom of the waste liquid reactor through the screening net to realize the automatic separation of precipitate and waste liquid. At the same time, the middle plate installed and positioned on one side of the screening net can not only install and position the screening net, but also support the bottom rod that runs through it, to ensure that the screening net that separates the precipitate will not affect the normal rotation of the bottom rod;

[0053] 4. In the copper-containing waste liquid treatment equipment and treatment method, when the deposited waste liquid is treated, the design of the inner wall slope of the waste liquid reactor can ensure that the deposited liquid is drained more smoothly. At the same time, the sewage drain pipe and impurity drain port for draining the liquid and the deposited impurities will not affect the sweeping and cleaning of the inner wall of the waste liquid reactor by the sweeping and scraping plate, and are respectively located at multiple positions on the inner bottom of the waste liquid reactor, ensuring that the deposited impurities and liquid can be fully discharged when they are drained separately.

[0077] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0078] See also Figure 1-Figure 13The copper-containing waste liquid treatment equipment includes a waste liquid reactor 10, a support 20, a pretreatment box 30, an integrated stirring and cleaning mechanism 40 and a sedimentation and screening component 50. A plurality of groups of support columns 20 are installed at the bottom of the waste liquid reactor 10. The pretreatment boxes 30 are installed and positioned on both sides of the top of the waste liquid reactor 10 through a support seat 100. The bottom of the pretreatment box 30 is connected to the waste liquid reactor 10 through a discharge pipe 300. The interior of the waste liquid reactor 10 is provided with an integrated stirring and cleaning mechanism 40 extending to the outside. The side of the integrated stirring and cleaning mechanism 40 extends to the interior of the pretreatment box 30, and the material inside the pretreatment box 30 is stirred. A sedimentation and screening component 50 is arranged at the center of the interior of the waste liquid reactor 10. The sedimentation and screening component 50 is located on the side of the integrated stirring and cleaning mechanism 40. Among them, the integrated stirring and cleaning mechanism 40 includes The invention comprises a gear stirring assembly 60, which is installed at the center of the top of the waste liquid reactor 10 and extends to the inside of the waste liquid reactor 10. The gear stirring assembly 60 is movably connected to the top of the sedimentation and screening assembly 50, and stirs and precipitates the waste liquid inside the waste liquid reactor 10; and an inner wall sweeping assembly 70, which is connected to the gear stirring assembly 60 and driven by the gear stirring assembly 60, and the inner wall sweeping assembly 70 is arranged at the bottom of the sedimentation and screening assembly 50, and sweeps and cleans the inner wall of the waste liquid reactor 10; an eccentric stirring assembly 80, which is arranged on the left and right sides of the gear stirring assembly 60 and is driven by a group of gear stirring assemblies 60, and extends to the inside of the pretreatment box 30, and stirs the material inside the pretreatment box 30.
