Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment and reuse, in particular to a device for recycling electrode foil corrosion production wastewater. Background Technique

[0002] During the corrosion production process, since aluminum powder is generated under the action of corrosion on the aluminum foil, a large amount of water is required to wash the aluminum foil after the treatment tank to remove the aluminum powder. Since this water contains a large amount of aluminum powder, it needs to pass through a membrane cleaning mechanism before being recycled and reused in the liquid preparation system, resulting in a high cost. In addition, since the cleaning water of the aluminum foil cannot be quickly recycled and is circulated in the tank, the aluminum powder content will become higher and higher, and the cleaning effect will decrease accordingly.

[0003] Existing wastewater recycling devices usually directly filter the aluminum powder impurities in the wastewater, and cannot deposit the aluminum powder in the wastewater before filtering. Direct filtering will increase the filtering burden on the filter screen, reduce the service life of the filter screen. At the same time, after the filter screen is used for a period of time, it is also impossible to quickly wash the filter screen, resulting in the filter screen being easily blocked by aluminum powder and reducing the filtering effect of the filter screen. Summary of the Invention

[0004] In view of this, the purpose of the present utility model is to provide a device for recycling electrode foil corrosion production wastewater, so as to solve the problems that the existing wastewater recycling device has a poor filtering effect on wastewater and it is also difficult to quickly clean the impurities on the surface of the filter screen.

[0005] Based on the above purpose, the present utility model provides a device for recycling electrode foil corrosion production wastewater, including a tank for washing the aluminum foil, and a treatment tank for filtering the wastewater in the tank. A partition is fixedly connected in the treatment tank, and the partition divides the treatment tank into a filtering chamber and a clean water chamber, and several filter screens are installed in the filtering chamber;

[0006] There is a gap between the top of the partition and the inner wall of the treatment tank. A first circulation pump is installed between the tank and the treatment tank. The first circulation pump can pump the wastewater in the tank into the filtering chamber. The filter screen can filter the wastewater slowly rising in the filtering chamber. A flushing mechanism is arranged on the treatment tank, and the flushing mechanism can extract the clean water in the clean water chamber to flush the impurities on the filter screen.

[0007] Preferably, the number of filter screens in the filtering chamber is four, and the mesh numbers of the four filter screens increase from bottom to top.

[0008] Preferably, a second circulation pump is installed on the side of the treatment tank. The water inlet end of the second circulation pump extends into the clean water chamber through a connecting pipe. The water outlet end of the second circulation pump is fixedly connected with a delivery pipe, and the end of the delivery pipe extends into the tank.

[0009] Preferably, the flushing mechanism includes a plurality of flushing pipes embedded and connected to the inner wall of the processing tank. A third circulation pump is arranged between the tank body and the processing tank. The water inlet end of the third circulation pump is fixedly connected with a water suction pipe, and the end of the water suction pipe extends into the clean water chamber. The water outlet end of the third circulation pump is connected to the plurality of flushing pipes through a branch pipe.

[0010] Preferably, the number of the flushing pipes is the same as that of the filter meshes. Water outlet holes are formed in the flushing pipes. The water outlet holes on each flushing pipe are flush with the lower surface of the adjacent filter mesh, so that the water sprayed out of the water outlet holes of the flushing pipes can clean the lower surface of the filter mesh.

[0011] Preferably, a plurality of impurity cleaning ports are formed in the processing tank, and sealing plates are installed in the impurity cleaning ports.

[0012] The beneficial effects of the present utility model are as follows:

[0013] Since the wastewater enters from the bottom of the filtration chamber and rises slowly, the filter mesh can filter the wastewater rising slowly in the filtration chamber. At the same time, the aluminum powder impurities in the wastewater will settle at the bottom of the filtration chamber, so that the filtering effect on the aluminum powder impurities in the wastewater is better. The filtered wastewater enters the clean water chamber through the top of the partition plate for temporary storage.

[0014] When it is necessary to flush the lower surface of the filter mesh, the third circulation pump pumps the water in the clean water chamber and supplies it to the flushing pipes through the branch pipe. The water outlet holes on each flushing pipe are flush with the lower surface of the adjacent filter mesh, and the water in the flushing pipes will be sprayed out through the water outlet holes to clean the lower surface of the filter mesh, avoiding blockage of the filter mesh and improving the filtering effect of the filter mesh.

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in detail with reference to specific embodiments and the accompanying drawings.

[0022] As Figure 1 、 Figure 2 、 Figure 3 As shown, an electrode foil etching production wastewater recycling device includes a tank body 1 for flushing aluminum foil and a treatment box 2 for filtering the wastewater in the tank body 1. A partition board 4 is fixedly connected inside the treatment box 2. The partition board 4 divides the treatment box 2 into a filtration chamber 5 and a clean water chamber 6, and a plurality of filter screens 7 are installed in the filtration chamber 5;

[0023] There is a gap between the top of the partition board 4 and the inner wall of the treatment box 2. A first circulation pump 3 is installed between the tank body 1 and the treatment box 2. The water inlet end of the first circulation pump 3 extends into the tank body 1 through a water pipe, and the water outlet end of the first circulation pump 3 extends into the filtration chamber 5 through a water outlet pipe and is located at the bottom of the filtration chamber 5. The first circulation pump 3 can pump the wastewater in the tank body 1 into the filtration chamber 5, and the filter screen 7 can filter the wastewater slowly rising in the filtration chamber 5. A flushing mechanism is provided on the treatment box 2, and the flushing mechanism can extract the clean water in the clean water chamber 6 to flush the impurities on the filter screen 7.

[0024] Since the wastewater enters from the bottom of the filtration chamber 5 and slowly rises within the filtration chamber 5, the filter net 7 can filter the wastewater slowly rising within the filtration chamber 5. Meanwhile, the aluminum powder impurities in the wastewater will settle at the bottom of the filtration chamber 5, resulting in a better filtration effect for the aluminum powder impurities in the wastewater. The filtered wastewater enters the clean water chamber 6 through the top of the partition plate 4 for temporary storage. When it is necessary to clean the surface of the filter net 7, the flushing mechanism extracts the clean water in the clean water chamber to flush the lower surface of the filter net 7, so as to clean the impurities adhering to the surface of the filter net 7.

[0025] In a preferred embodiment of the present utility model, the number of the filter nets 7 in the filtration chamber 5 is four, and the mesh number of the four filter nets 7 increases from bottom to top, with the minimum being 100 mesh and the maximum being 3000 mesh.

[0026] In another preferred embodiment of the present utility model, a second circulation pump 8 is installed on the side of the treatment tank 2. The water inlet end of the second circulation pump 8 extends into the clean water chamber 6 through a connecting pipe. The water outlet end of the second circulation pump 8 is fixedly connected with a delivery pipe 9, and the end of the delivery pipe 9 extends into the tank body 1. The second circulation pump 8 can extract the filtered wastewater in the clean water chamber 6 and transport it into the tank body 1 through the delivery pipe 9 to continue flushing the surface of the aluminum foil, improving the utilization efficiency of the cleaning water.

[0027] In still another preferred embodiment of the present utility model, the flushing mechanism includes a plurality of flushing pipes 10 embedded and connected to the inner wall of the treatment tank 2. Grooves for embedding and installing the flushing pipes 10 are provided on the inner wall of the treatment tank 2. A third circulation pump 11 is arranged between the tank body 1 and the treatment tank 2. The third circulation pump 11 can be installed on the treatment tank 2 through an external support. The water inlet end of the third circulation pump 11 is fixedly connected with a water extraction pipe 12, and the end of the water extraction pipe 12 extends into the clean water chamber 6. The water outlet end of the third circulation pump 11 is connected to the plurality of flushing pipes 10 through a branch pipe 13. The number of the flushing pipes 10 is the same as that of the filter nets 7. Water outlet holes are provided on the flushing pipes 10. The water outlet holes on each flushing pipe 10 are flush with the lower surface of its adjacent filter net 7, so that the water sprayed out from the water outlet holes of the flushing pipes 10 can clean the lower surface of the filter net 7.

[0028] Since the wastewater slowly rises from bottom to top in the filtration chamber 5, the impurities in the wastewater are likely to block the lower surface of the filter net 7. When it is necessary to flush the lower surface of the filter net 7, the third circulation pump 11 is started. The third circulation pump 11 extracts the water in the clean water chamber 6 and supplies it to the flushing pipes 10 through the branch pipe 13. Since the water outlet holes on each flushing pipe 10 are flush with the lower surface of its adjacent filter net 7, the water in the flushing pipes 10 will be sprayed out through the water outlet holes to clean the lower surface of the filter net 7, avoiding the blockage of the filter net 7 and improving the filtration effect of the filter net 7.

[0029] It should be noted that impurity cleaning ports are provided below each filter net 7, and the number of impurity cleaning ports is equal to the number of filter nets 7, which is convenient for cleaning the impurities washed off from the filter net 7. A sealing plate 14 is installed in the impurity cleaning port, and the sealing plate 14 can be detachably installed at the impurity cleaning port through bolts. Removing the sealing plate 14 can clean the impurities washed off from the filter net 7 by the flushing mechanism.
