Abstract

This invention discloses an electrolytic waste liquid treatment device for hydrometallurgical zinc production, relating to the field of electrolytic waste liquid treatment technology. The invention includes a base plate, with a support column fixedly installed on the upper end of the outer wall of the base plate, and a connecting plate fixedly installed on the upper end of the outer wall of the support column. In use, when the activated alumina defluorinating agent stored in the alumina defluorinating agent storage box is saturated with fluorine, the lifting frame is raised, and the drive motor is started, causing the connecting rod and the intermediate shaft to rotate.

Description

Technical Field

[0001] This invention belongs to the field of electrolytic waste liquid treatment technology, and in particular relates to an electrolytic waste liquid treatment device in hydrometallurgical zinc production. Background Technology

[0002] Hydrometallurgical zinc refining refers to the process of dissolving zinc in zinc calcined sand or other zinc sulfide materials and zinc sulfide concentrates in an aqueous solution to extract metallic zinc or zinc compounds. It is the main method of modern zinc refining. Due to the increasing scarcity of zinc concentrate resources, many smelting enterprises have begun to use zinc oxide materials with more complex compositions and lower prices for electrolytic zinc production. These zinc oxide materials mainly come from self-produced iron ore slag and lead-silver slag. Iron ore slag and lead-silver slag contain high levels of fluorine, which enters the hydrometallurgical zinc refining system along with the zinc oxide materials, causing fluorine to accumulate continuously in the system. The accumulation of fluoride not only causes severe corrosion to the entire hydrometallurgical zinc smelting system, but also necessitates the removal of fluoride from the electrolyte. Generally, activated alumina is used as a defluorinating agent. This alumina defluorinating agent is a white granular product with a large defluorination capacity, good physical properties, high strength, and is non-toxic and odorless. It does not soften, expand, or crack when submerged in water, making it completely reliable. It is also easily regenerated and has a long lifespan. However, using activated alumina as a defluorinating agent to remove fluoride from electrolytic wastewater still has the following drawbacks in practical application:

[0003] 1. After a period of use, if the activated alumina defluorinating agent absorbs too much fluorine, it needs to be regenerated in a regenerator. Generally, the activated alumina defluorinating agent is soaked in sodium hydroxide solution or aluminum sulfate solution for regeneration. Currently, the regeneration operation of alumina defluorinating agent requires manual soaking, which is quite troublesome. In addition, manual operation will expose workers to electrolytic waste liquid, which is dangerous.

[0004] 2. When using existing activated alumina defluorinating agents to defluorinate electrolytic waste liquid, the activated alumina defluorinating agents are generally placed directly in the electrolytic waste liquid, resulting in poor defluorination effect.

[0005] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an electrolytic waste liquid treatment device in the hydrometallurgical zinc production process. By driving a motor, two sliding blocks can slide to the right in the arc-shaped sliding grooves on both sides, so that the saturated active alumina defluorinating agent stored in the alumina defluorinating agent storage box can be immersed in sodium hydroxide solution for regeneration treatment. This solves the problem that the regeneration operation of existing alumina defluorinating agents requires manual soaking, which is relatively troublesome, and that manual operation will cause workers to come into contact with electrolytic waste liquid, which is dangerous.

[0011] Furthermore, connecting blocks one are fixedly installed circumferentially on the inner wall of the rotating frame, and a light rod is slidably connected inside each connecting block one. The lower ends of the outer walls of all the light rods are simultaneously fixedly connected to the upper ends of the outer walls of the lifting frame.

Then, the lifting frame is lowered, allowing the saturated active alumina defluorinating agent stored in the alumina defluorinating agent storage box to be immersed in sodium hydroxide solution for regeneration.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0031] As attached Figures 1-7The electrolytic waste liquid treatment equipment shown includes a base plate 100. A support column 110 is fixedly installed on the upper end of the outer wall of the base plate 100. A connecting plate 120 is fixedly installed on the upper end of the outer wall of the support column 110. Connecting side plates 200 are symmetrically fixedly installed on the front and rear ends of the outer wall of the connecting plate 120. Each connecting side plate 200 has an arc-shaped sliding groove 210. A sliding block 220 is slidably connected to each of the two arc-shaped sliding grooves 210. A connecting rod 230 is fixedly installed on the opposite side of the outer wall of each of the two sliding blocks 220. A connecting rod 240 is rotatably connected to the opposite side of the upper end of the outer wall of each of the two connecting rods 230. A rotating frame 250 is rotatably connected to the lower end of the outer wall of each of the two connecting rods 240. A liftable lifting mechanism is provided below the rotating frame 250. A lifting frame 400 has filter holes 410 arranged circumferentially on its side wall. Inside the lifting frame 400 is a rotatable alumina defluorinating agent storage frame 500. An electrolytic waste liquid frame 101 is fixedly installed on the upper left side of the outer wall of the base plate 100, and a regenerated liquid frame 105 is fixedly installed on the upper right side of the outer wall of the base plate 100. An input pipe 103 and an output pipe 104 are respectively connected to the front and rear ends of the outer wall of the electrolytic waste liquid frame 101. A protective frame 102 is fixedly installed at the opening at the upper end of the outer wall of the electrolytic waste liquid frame 101. The alumina defluorinating agent storage frame 500 has dense mesh 510 on its side wall. Electrolytic waste liquid flows into the electrolytic waste liquid frame 101 from the input pipe 103. The active alumina defluorinating agent stored in the alumina defluorinating agent storage frame 500 in the lowered lifting frame 400 is then absorbed by the filter holes. The alumina defluorinating agent absorbs fluorine from the electrolytic waste liquid. After the active alumina defluorinating agent stored in the alumina defluorinating agent storage box 500 is saturated with absorbed fluorine, the device can move the lifting box 400 to the regeneration liquid box 105 for soaking. The saturated active alumina defluorinating agent is regenerated by the sodium hydroxide solution in the regeneration liquid box 105. Connecting rods 221 are fixedly installed on opposite sides of the outer walls of the two sliding blocks 220. Intermediate shafts 222 are fixedly installed on opposite sides of the lower outer walls of the two connecting rods 221. The intermediate shafts 222 pass through the connecting side plate 200 and are rotatably connected to the connecting side plate 200. A motor plate 224 is fixedly installed on the rear side of the outer wall of the rear connecting side plate 200. A drive mechanism is fixedly installed on the upper side of the outer wall of the motor plate 224. A drive motor 225 has a connecting shaft 223 fixedly mounted on its output end. The front end of the connecting shaft 223 is fixedly connected to the lower end of the outer wall of the connecting rod 221 on the rear side. When the drive motor 225 is started, it drives the two connecting rods 221 and the intermediate shaft 222 to rotate, allowing the two sliding blocks 220 to slide in the arc-shaped sliding grooves 210 on both sides. This drives the two connecting rods 230 and 240 to rotate, allowing the rotating frame 250 to move left and right around the intermediate shaft 222. Connecting blocks 300 are fixedly mounted circumferentially on the inner wall of the rotating frame 250. Each connecting block 300 has a smooth rod 310 slidably connected inside it. The lower end of the outer wall of all the smooth rods 310 is simultaneously fixedly connected to the upper end of the outer wall of the lifting frame 400.Connecting blocks 2 600 are fixedly installed circumferentially on the inner wall of the rotating frame 250. Each connecting block 2 600 is rotatably connected to a threaded sleeve 610. Rotation limit plates 620 are symmetrically fixedly installed at the upper and lower ends of the outer wall of each threaded sleeve 610. A screw 630 is threadedly connected inside each threaded sleeve 610. The lower end of the outer wall of each screw 630 is rotatably connected to the upper end of the outer wall of the lifting frame 400. Rotation of the threaded sleeve 610 causes the screw 630 to move up and down, thus moving the lifting frame 400 up and down, and causing the guide rod 310 to slide up and down inside the connecting block 1 300. A motor plate 2 650 is fixedly installed at the lower end of the inner wall of the lifting frame 400. A lifting motor 660 is fixedly installed at the upper middle part of the outer wall of the 650. A rotating shaft 670 is fixedly installed at the output end of the lifting motor 660. An intermediate gear 680 is fixedly installed at the upper end of the outer wall of the rotating shaft 670. A drive gear 640 is fixedly installed on the outer wall of each threaded sleeve 610. All drive gears 640 are meshed with the intermediate gear 680. The lifting motor 660 drives the intermediate gear 680 to rotate, which in turn drives all drive gears 640 to rotate, causing all threaded sleeves 610 to rotate. A through hole 651 is provided on the motor plate 650, which allows the screw 630 to pass through the motor plate 650.

[0032] Electrolytic waste liquid flows from input pipe 103 into electrolytic waste liquid frame 101. The starting of lifting motor 660 drives intermediate gear 680 to rotate, which in turn drives all drive gears 640, causing all threaded sleeves 610 to rotate. The rotation of the threaded sleeves 610 causes screw 630 to move up and down, thus moving lifting frame 400 up and down. This, in turn, causes smooth rod 310 to slide up and down within connecting block 300. The activated alumina defluorinating agent stored in alumina defluorinating agent storage box 500 within the lowered lifting frame 400 absorbs fluoride from the electrolytic waste liquid. After a period of use, when the activated alumina defluorinating agent storage box 500... After the activated alumina defluorinating agent stored in the storage box is saturated with fluorine, the lifting frame 400 is raised, and the drive motor 225 is started to rotate the two connecting rods 221 and the intermediate shaft 222. This allows the two sliding blocks 220 to slide to the right in the arc-shaped sliding grooves 210 on both sides, driving the two connecting rods 230 and 240 to rotate to the right. This causes the rotating frame 250 to rotate to the right around the intermediate shaft 222, moving the rotating frame 250 directly above the regeneration liquid frame 105. Then, the lifting frame 400 is lowered, allowing the saturated activated alumina defluorinating agent stored in the alumina defluorinating agent storage box 500 to be immersed in sodium hydroxide solution for regeneration. Example 2

[0033] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0034] As attached Figure 4 and Figure 6 The electrolytic waste liquid treatment equipment shown is used in a wet zinc smelting process. All the smooth rods 310 have connecting frames 700 fixedly installed on their outer walls. All the connecting frames 700 have motor mounting frames 710 fixedly installed. A rotating motor 720 is fixedly installed inside the motor mounting frame 710. A connecting shaft 730 is fixedly installed at the output end of the rotating motor 720. An upper linkage plate 740 is fixedly installed at the lower end of the outer wall of the connecting shaft 730. Connecting screws 750 are threaded around the outer wall of the upper linkage plate 740. A lower linkage plate 760 is threaded at the lower end of the outer wall of all the connecting screws 750. A connecting shaft 770 is fixedly installed at the lower end of the outer wall of the lower linkage plate 760. The lower end of the outer wall of the connecting shaft 770 passes through the lifting frame 400 and is fixedly installed at the upper end of the outer wall of the alumina defluorinating agent storage frame 500.

[0035] Specifically, starting the rotating motor 720 can drive the connecting shaft 730, the upper linkage plate 740, and the connecting shaft 770 to rotate, thereby causing the alumina defluorinating agent storage box 500 in the lifting frame 400 to rotate. This allows the alumina defluorinating agent storage box 500 to both agitate the electrolytic waste liquid in the electrolytic waste liquid box 101 during defluorination treatment, thus improving the defluorination efficiency, and agitate the sodium hydroxide solution in the regeneration liquid box 105 during regeneration treatment, thus improving the regeneration efficiency of the alumina defluorinating agent. Example 3

[0036] Based on Embodiment 2, the solution in Embodiment 2 will be further described in detail below, with reference to the specific working method described in detail:

[0037] As attached Figure 4 and Figure 6 The device shown is an electrolytic waste liquid treatment device in a wet zinc smelting process. The upper part of the outer wall of the alumina defluorinating agent storage box 500 is rotatably connected to a door 501. The door 501 and the upper part of the outer wall of the alumina defluorinating agent storage box 500 are fixedly installed with a latch 502. The user can replenish or replace the alumina defluorinating agent in the alumina defluorinating agent storage box 500 by opening the door 501. The lower part of the outer wall of the lifting frame 400 is detachably connected to a material changing plate 401. The material changing plate 401 is circumferentially threaded with disassembly screws 402.

[0038] Specifically, the user can unscrew the disassembly screws 402 to remove the material replacement plate 401, then remove all the connecting screws 750, separate the upper linkage plate 740 and the lower linkage plate 760, and remove the alumina defluorinating agent storage box 500 from the device. At this time, the dense mesh 510 can be cleaned, and the alumina defluorinating agent in the alumina defluorinating agent storage box 500 can be replenished or replaced by opening the door 501.

[0039] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
