Description

Technical Field

[0001] The invention relates to the technical field of zinc electrolysis production, and in particular to an anode plate cleaning device. Background Art

[0002] The electrolytic deposition of zinc is the last step of hydrometallurgy, which is the process of extracting pure metallic zinc from zinc sulfate aqueous solution by electrolysis. The electrolytic deposition of zinc sulfate solution is to mix the purified zinc sulfate solution with the waste electrolyte in a certain proportion and continuously feed it into the electrolytic cell from the inlet end. The anode and cathode are suspended in parallel and staggered in the cell, and direct current is passed. Metallic zinc is deposited at the cathode and oxygen is released at the anode. After a certain period of electrolysis, the cathode plate is taken out, and the zinc flakes deposited on the cathode plate are peeled off and sent to the melting and casting process.

[0003] During the zinc electrolysis process, a layer of anode mud will gradually accumulate on the surface of the anode plate. This anode mud is mainly composed of undissolved impurities and metals. If it is not cleaned in time, it will affect the electrolysis efficiency and product quality. The common method of cleaning anode mud is through chemical cleaning, such as acid cleaning, alkaline cleaning, etc.; clean the dirt and oxides on the surface of the zinc anode plate.

[0004] The specific cleaning method is soaking. Soak in a mixed solution containing reducing substances and acidic substances to dissolve and fall off the anode mud. However, in the actual cleaning process, the traditional soaking method uses a hanger to lift the anode plate into the soaking tank. The soaking of the anode plate takes a long time. The main reason is that the anode mud adheres to the surface of the anode plate. The traditional soaking method relies on natural shedding and lacks physical intervention methods. Traditional physical intervention can only manually clean the surface of the anode plate. During manual cleaning, the anode mud on the surface of the anode plate is removed by scraping or shoveling with cleaning tools. This method is not only inefficient, but the shovel used in the manual cleaning process is also easy to damage the surface of the anode plate. Summary of the invention

DETAILED DESCRIPTION

[0028] like Figure 1 , 2 As shown in Figure 6, an anode plate cleaning device is used to clean the anode mud attached to the body of the anode plate 5. It mainly includes several parts, such as a soaking tank 1, a beating mechanism 2, a movable lower plate mechanism 3, and a transition bearing mechanism 4. The soaking tank 1 is the last cleaning step of the anode plate 5, so the equipment needs to be set up and run on the soaking tank 1, and the soaking liquid is stored in the soaking tank 1. Specifically, a transition bearing mechanism 4 for placing the anode plate 5 is set above one end of the soaking tank 1; a traveling rail 8 is fixed along the inner side of the side wall of the soaking tank 1; the movable lower plate mechanism 3 reciprocates along the traveling rail 8 toward the two ends of the soaking tank 1; the movable lower plate mechanism 3 can transfer the anode plate 5 placed on the transition bearing mechanism 4 to the beating mechanism 2, and return to its original position after beating, rinsing and soaking are completed, so as to facilitate lifting and transfer. A beating mechanism 2 is installed near the middle of the soaking tank 1; after the movable lower plate mechanism 3 moves to the bottom of the beating mechanism 2, the anode plates 5 move up in turn and enter the beating mechanism 2 for vibration, and return to the movable lower plate mechanism 3 after the vibration is completed; the movable lower plate mechanism 3 moves all the vibrated anode plates 5 downward to immerse the anode plates 5 in the soaking tank 1; the anode plates 5 are reset after being soaked, and then transported to the transition bearing mechanism 4 through the movable lower plate mechanism 3.

[0029] like Figure 3 , 4As shown, the transition bearing mechanism 4 includes: an outer frame 411, an inner frame 412, a first slide rail 414, a support rod 415, and a lifting cylinder 416; the inner frame 412 is slidably provided on the inner side of the outer frame 411; the first slide rail 414 is vertically fixed inside the outer frame 411; a slide groove 418 is provided on the back of the inner frame 412, and the slide groove 418 cooperates with the first slide rail 414; a lifting cylinder 416 is fixed on the inner side of the outer frame 411, and the telescopic end of the lifting cylinder 416 is fixed to the bottom of the support rod 415; the support rod 415 is controlled to move up and down by the lifting cylinder 416; a sleeve plate 417 is fixed above the lifting cylinder 416; the sleeve plate 417 is fixed to the middle part of the outer frame 411; the telescopic end of the lifting cylinder 416 passes through the sleeve plate 417 and is connected to the bottom of the support rod 415; a first notch 413 is opened at the top edge of the inner frame 412 corresponding to the position where the anode plate 5 is placed. After the inner frame 412 is raised to the highest position, the height of the first notch 413 of the inner frame 412 is higher than the top of the outer frame 411. The transition bearing mechanism 4 mainly plays the role of placing the anode plate 5. Before the anode plate 5 transitions to the slapping mechanism 2, the lower plate moving mechanism 3 needs to be used to pick up and place the anode plate 5 on the transition bearing mechanism 4.

[0030] like Figure 3 , 5 6, the lower plate moving mechanism 3 comprises: a bottom plate frame 311, a running wheel 313, a first hoist 314, and a lifting frame 315; a running wheel 313 is provided below the bottom plate frame 311, and the running wheel 313 is driven by a motor to move along the travel rail 8. A through hole for lowering the anode plate 5 is provided on the bottom surface of the bottom plate frame 311; second slide rails 316 are vertically fixed at the four corners of the bottom plate frame 311; the tops of the two second slide rails 316 at one end of the bottom plate frame 311 are fixed by a connecting plate 312; the first hoist 314 is fixed on the connecting plate 312, and the connecting plate 312 provides a fixed position while ensuring the supporting strength of the second slide rails 316. The connecting plate 312 is provided with a through hole correspondingly; the rope of the first hoist 314 passes through the through hole to be connected and fixed to the lifting frame 315; the lifting frame 315 is provided with a slide groove 418 corresponding to the position of the second slide rail 316; the lifting frame 315 is controlled by the first hoist 314 to move up and down along the second slide rail 316. The first hoists 314 are arranged in groups on the left and right, and are raised and lowered synchronously. After the lifting frame 315 is lowered to the lowest height, the anode plate 5 passes through the through hole of the bottom frame 311 and enters the soaking tank 1; the first hoists 314 located at both ends of the bottom frame operate synchronously.

[0031] It should be noted that the width of the cross beam 5.1 of the anode plate 5 should be greater than the width of the lifting frame 315, and greater than or equal to the width of the inner frame 412. The cross beam 5.1 of the anode plate 5 is the main mounting support position; and the movable lower plate mechanism 3 and the transition bearing mechanism 4 have overlapping positions, so when the two mechanisms overlap, it must be ensured that the cross beam 5.1 of the anode plate 5 can be placed on the inner frame 412 and the lifting frame 315 at the same time, and the anode plate 5 will be separated from the inner frame 412 after the subsequent lifting frame 315 is raised.

[0032] like Figure 2 , 7 As shown, the beating mechanism 2 includes a frame 221, a rapping plate 211, a push plate cylinder 212, a fixed plate 213, a lifting plate frame 214, and a second winch 215; the frame 221 is fixedly mounted above the soaking tank 1; the two sides of the frame 221 along the moving direction of the bottom plate frame 311 are open structures; it is convenient to move the lower plate mechanism 3 in and out. The inner side of the frame 221 is symmetrically hinged with a rapping plate 211; the top of the rapping plate 211 is provided with a hinge rod 216, the top of the hinge rod 216 is hinged to the top surface of the frame 221, the back of the rapping plate 211 is hinged to the telescopic end of the push plate cylinder 212, the end of the push plate cylinder 212 is hinged to the fixed plate 213, and the fixed plate 213 is fixed at the open position of the frame 221. The rapping plate 211 rotates inward from the open structure to slap the two sides of the anode plate 5; the edge of the rapping plate 211 is provided with a convex ridge; to prevent the rapping plate 211 from being completely attached to the anode plate 5, the edge of the anode plate 5 is mainly rapped. A gap is reserved between the rapping plates 211 for lifting the anode plate 5 to enter, and guide rails 218 are fixed on the inner wall of the frame 221 on both sides of the gap; the plate lifting frame 214 moves up and down along the guide rails 218; a hook 217 that cooperates with the cross beam 5.1 of the anode plate 5 is fixed at the bottom of the plate lifting frame 214; the plate lifting frame 214 is movably provided with a guide wheel 219 corresponding to the position of the guide rail 218; the guide wheel 219 controls the plate lifting frame 214 to move up and down along the guide rail 218; a second winch 215 is fixed on the top of the frame 221; the lifting rope of the second winch 215 is fixed to the top of the plate lifting frame 214. Before rapping, the anode plate 5 on the movable lower plate mechanism 3 needs to be moved up to the rapping area by means of the hook 217. The hook 217 of the plate lifting frame 214 is provided with a second notch 220 for placing the crossbeam 5.1 of the anode plate 5.

[0033] like Figure 6 , 7As shown, when the beating and descending are completed, nozzles 6 are fixed at the bottom of both sides of the frame 221, and the nozzles 6 are connected to the water source through pipes and are opened and closed by electric valves; the nozzles 6 are flushed toward the surface of the anode plate 5. The anode plate 5 after beating is subjected to secondary treatment. A splash-proof curtain 7 is installed at the open structure of the frame 221. During beating, the anode mud is prevented from splashing outside the frame 221. If the fixing method is not separately introduced above, it is welded or threaded fastened using the common technical means of technical personnel in the industry.

[0034] Implementation process:

[0035] The original treatment process is to directly soak the anode plate 5 by using the existing hanger to directly hang the anode plate 5 into the soaking tank 1 for soaking for thirty minutes. Anode mud remains, and the operator needs to take out the anode plate 5 and clean it manually for a second time.

[0036] The anode plate 5 is directly flushed by flushing equipment alone, and the flushing time is 10 minutes. The flushing time is long and the water consumption is large. Some anode mud that is difficult to fall off is attached to part of the anode plate 5, and the difficulty of manual cleaning is reduced.

[0037] The cleaning device can complete the above three-step treatment process, that is, vibrating twice, then flushing for five minutes, and finally soaking for fifteen minutes. The cleaning effect is remarkable, and most of the manual work only needs to check the cleaning effect, and subsequent manual cleaning can almost be avoided.

[0038] Here’s how it works:

[0039] The anode plates 5 are suspended in batches above the inner frame 412 of the transition bearing mechanism 4 through the hanger in the factory area, and placed in the first slot 413, with the inner frame 412 in a raised state; then the lower plate frame is moved to enter the inner side of the inner frame 412, and the inner frame 412 descends, so that the crossbeam 5.1 of the anode plate 5 contacts the second slot 220 of the lifting frame 315 and disengages from the first slot 413, and then the lower plate frame is moved toward the beating mechanism 2, and the plate lifting frame 214 in the beating mechanism 2 lifts the anode plates 5 in turn; after each anode plate 5 is beaten and falls back to the lifting frame 315, it is sprayed and rinsed until all the anode plates 5 of the batch are beaten and rinsed; finally, the lower plate frame is moved back to the inner side of the inner frame 412, the inner frame 412 rises, the anode plates 5 are disengaged from the second slot 220 again, and the anode plates 5 enter the first slot 413; the hanger lifts and transfers the cleaned anode plates 5 of the batch.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
