Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology in the production of etched foil, and in particular to a device for treating wastewater from the production of etched foil for aluminum electrolytic capacitors. Background Technology

[0002] As an important raw material for the production of aluminum electrolytic capacitors, etched foil undergoes extensive cleaning with ultrapure water during the production process, resulting in a large amount of cleaning wastewater. To avoid the impact of acidic wastewater on the natural environment, the cleaning wastewater needs to be treated before it can be discharged.

[0003] A search revealed that the utility model patent with authorization announcement number CN215828488U discloses a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors. The device uses an automatic cleaning plate, which automatically removes the flocculent material from the upper part of the screen without the need for electrical equipment. This makes the wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors conform to the concept of green and environmentally friendly development.

[0004] Although the above-mentioned device can push the flocculent material to the side of the sealing cover by using the reset automatic cleaning plate, it is still necessary to manually reach into the inside of the treatment box to remove the accumulated flocculent material when cleaning it later. The operation is too inconvenient. In addition, the removed flocculent material is often still in a damp state, so it is easy for wastewater to drip into the working environment and cause pollution after being removed from the inside of the treatment box.

[0005] Therefore, it is necessary to invent a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors. This device allows for more convenient removal and cleaning of flocculent material, while preventing residual wastewater from the flocculent material from falling into the working environment. It offers better practical performance and solves the problem mentioned in the background art where manual insertion into the treatment box is still required to remove accumulated flocculent material, which is inconvenient. Furthermore, the removed flocculent material is often still damp, which can easily lead to wastewater dripping into the working environment and causing pollution after being removed from the treatment box.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors, comprising:

[0008] A wastewater containment mechanism for containing the corrosion foil production wastewater to be treated;

[0009] Wastewater treatment apparatus, wherein the wastewater treatment apparatus is used to treat the corrosion foil production wastewater entering the wastewater receiving apparatus; and

[0010] A suspended matter cleaning mechanism, comprising a cleaning component and a collection component;

[0011] The cleaning assembly includes two parallel sliding rods that slide through the side wall of the processing box. A pull rod is fixedly installed between the two sliding rods. A suspended matter scraper is fixedly installed at the right end of the two sliding rods. The suspended matter scraper slides against the top of the sieve plate.

[0012] The collection assembly includes a guide hopper fixedly installed on the left side of the processing box and located below the waste outlet. Below the guide hopper is a placement plate fixedly connected to the processing box. A limiting groove is opened on the top of the placement plate, and a collection bucket is placed inside the limiting groove.

[0013] According to at least one embodiment of the present disclosure, a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors is provided, wherein the wastewater containing mechanism includes a treatment tank, a base is fixedly provided at the bottom of the treatment tank, an inlet pipe is fixedly provided through the top left side of the treatment tank, an outlet pipe is fixedly provided through the bottom of the treatment tank, a water pump is provided on the inlet pipe, and a shut-off valve is provided on the outlet pipe.

[0014] According to at least one embodiment of the present disclosure, a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors is provided with a waste discharge port on the top left side of the treatment box, and a sealed door that is movably connected to the treatment box via a hinge on the left side of the treatment box.

[0015] According to at least one embodiment of the present disclosure, a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors includes a sieve plate, a first buffer inclined plate, a second buffer inclined plate, and two filter screens arranged sequentially from top to bottom. The sieve plate, the first buffer inclined plate, the second buffer inclined plate, and the two filter screens are all fixedly connected to the inner wall of the treatment tank.

[0016] According to at least one embodiment of the present disclosure, a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors is provided, wherein wastewater channels are provided between the right end of the first buffer inclined plate and the inner wall of the treatment tank, and between the left end of the second buffer inclined plate and the inner wall of the treatment tank, and an activated carbon filling layer is filled between the two filter screens.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention features a suspended solids cleaning mechanism. When cleaning the flocculent material sieved from the top of the screen plate, the sealing door is opened, and then a pull rod and sliding rod pull the suspended solids scraper. During the movement of the scraper, the flocculent material on the top of the screen plate is pushed until it is discharged through the waste outlet. After discharge, the flocculent material falls into the guide hopper under gravity, and finally, guided by the guide hopper, falls into the collection bucket for collection. Compared to existing technologies, this invention allows for more convenient removal and cleaning of flocculent material, while preventing residual wastewater from the flocculent material from entering the working environment, resulting in better practical performance.

[0029] Figure 2 This is a schematic diagram of the wastewater containing mechanism 1 and the wastewater treatment mechanism 2 of a wastewater treatment apparatus for the production of etched foil for aluminum electrolytic capacitors according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the suspended solids cleaning mechanism 3 of a wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the wastewater treatment device for the production of etched foil for aluminum electrolytic capacitors disclosed herein may include components such as a wastewater containing mechanism 1, a wastewater treatment mechanism 2, and a suspended solids removal mechanism 3.

[0032] like Figure 2 As shown in this disclosure, the wastewater containing mechanism 1 includes a treatment tank 11. A base 12 is fixedly installed at the bottom of the treatment tank 11. An inlet pipe 13 is fixedly installed through the top left side of the treatment tank 11. An outlet pipe 14 is fixedly installed through the bottom of the treatment tank 11. A water pump 15 is installed on the inlet pipe 13. A shut-off valve is installed on the outlet pipe 14. A waste discharge port 16 is opened at the top left side of the treatment tank 11. A sealing door 17 is provided on the left side of the treatment tank 11 and is movably connected to the treatment tank 11 by a hinge.

[0033] This allows the water pump 15 to input the wastewater to be treated into the treatment tank 11 through the inlet pipe 13, and the treated wastewater is then discharged through the outlet pipe 14.

[0034] like Figure 2As shown, in a preferred embodiment, the wastewater treatment mechanism 2 includes a sieve plate 21, a first buffer inclined plate 22, a second buffer inclined plate 23, and two filter screens 24 arranged sequentially from top to bottom. The sieve plate 21, the first buffer inclined plate 22, the second buffer inclined plate 23, and the two filter screens 24 are all fixedly connected to the inner wall of the treatment tank 11. Wastewater channels are provided between the right end of the first buffer inclined plate 22 and the inner wall of the treatment tank 11, and between the left end of the second buffer inclined plate 23 and the inner wall of the treatment tank 11. An activated carbon filling layer 25 is filled between the two filter screens 24.

[0035] Therefore, after the wastewater enters the treatment tank 11, the sieve plate 21 removes the suspended solids in the wastewater. The wastewater then falls under the action of gravity and falls to the top of the filter screen 24 after being buffered by the first buffer plate 22 and the second buffer plate 23. When passing through the two filter screens 24, it is adsorbed and purified by the activated carbon filling layer 25.

[0036] like Figure 3 As shown in this disclosure, the suspended solids cleaning mechanism 3 includes a cleaning component and a collection component. The cleaning component includes two parallel sliding rods 31 that slide through the side wall of the treatment tank 11. A pull rod 32 is fixedly installed between the two sliding rods 31. A suspended solids scraper 33 is fixedly installed at the right end of the two sliding rods 31. The suspended solids scraper 33 slides against the top of the screen plate 21. The collection component includes a guide bucket 34 fixedly installed on the left side of the treatment tank 11 and located below the waste outlet 16. A placement tray 35 fixedly connected to the treatment tank 11 is installed below the guide bucket 34. A limiting groove is opened on the top of the placement tray 35, and a collection bucket 36 is placed inside the limiting groove.

[0037] Therefore, when cleaning the flocculent material screened from the top of the sieve plate 21, the sealing door 17 is opened, and then the suspended material scraper 33 is pulled by the pull rod 32 and the sliding rod 31. During the movement of the suspended material scraper 33, the flocculent material on the top of the sieve plate 21 is pushed until the flocculent material is discharged through the waste outlet 16. After being discharged, the flocculent material falls into the guide bucket 34 under the action of gravity, and finally falls into the collection bucket 36 under the guidance of the guide bucket 34 and is collected. Compared with the existing technology, it is more convenient to remove and clean the flocculent material, and at the same time, it can prevent the wastewater remaining in the flocculent material from falling into the working environment, and the actual use effect is better.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
