Technical Field

[0001] The present application relates to the technical field of impurity removal of strip cleaning fluids, and in particular to a regeneration and filtration device for foil cleaning fluids. Background Art

[0002] Foil is widely used in production, typically in thin sheets. Ultra-thin foil can be less than 0.02mm thick. During production, transportation, and storage, foil may come into contact with oil, dust, fingerprints, and other contaminants. These contaminants can affect the foil's surface quality and performance, necessitating cleaning with a cleaning solution to remove them.

[0003] At present, most foil cleaning lines in the domestic metallurgical industry produce a large amount of impurities or metal powder (such as copper powder) during the cleaning process.

Obviously, the embodiments described in this application are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Example 1

[0032] See Figures 1 to 4 , further explain this application:

[0033] Combine Figure 1 , a foil cleaning liquid regeneration filter device is used to filter impurities in the cleaning liquid, which includes a bracket 1 and at least one filter unit 2 arranged on the bracket 1, the bracket is used to install the filter unit 2, the filter unit 2 includes a heat exchange component 22 and at least one filter component 21, the filter component 21 is connected to the degreasing tank, and is used to filter the cleaning liquid in the degreasing tank; a filter circuit 10 is formed between the filter component 21 and the degreasing tank, so that the cleaning liquid can flow and circulate in the filter circuit 10 for filtration, so as to ensure that there are no impurities in the cleaning liquid, thereby avoiding damage to the surface of the foil during cleaning and affecting the surface quality of the foil.

[0034] In order to ensure that the cleaning fluid in the degreasing tank is always at the optimal temperature; Figure 1, further comprising a piping unit 3, which is connected to an external supply device and has a medium flowing therein for exchanging heat with the cleaning liquid. It should be noted that the medium can exchange heat with the cleaning liquid, heating or cooling the cleaning liquid to control the temperature of the cleaning liquid; the medium can be water. The piping unit 3 comprises a first pipe 31 and a second pipe 32, both of which are connected by pipes. A hot medium flows in the first pipe 31 for exchanging heat with the cleaning liquid to heat it; a cold medium flows in the second pipe 32 for exchanging heat with the cleaning liquid to cool it, thereby ensuring that the cleaning liquid in the degreasing tank is at an optimal temperature, thereby improving the cleaning effect on the foil.

[0035] Combine Figure 1 The heat exchange assembly 22 is connected to the piping unit 3 and the filter pipeline, respectively, for exchanging heat between the medium and the cleaning fluid. In this embodiment, the heat exchange assembly 22 is a plate heat exchanger, wherein a first channel and a second channel are defined within the plate heat exchanger. The first channel is connected to the filter pipeline, and the second channel is connected to the piping unit 3. In other words, the second channel is connected to the first pipeline 31 and the second pipeline 32. During operation, the cleaning fluid entering the first channel exchanges heat with the medium (cold medium or hot medium) entering the second channel to maintain the temperature of the cleaning fluid.

[0036] The heat exchange component 22 is connected to the liquid outlet pipe 2102 , so that when the filtered cleaning liquid enters the heat exchange component 22 , impurities in the cleaning liquid can be prevented from entering the heat exchange component 22 .

[0037] Combine Figure 2 The first pipeline 31 and the second pipeline 32 are each provided with a first on-off valve 4. The first pipeline 31 and the second pipeline 32 can be connected to the first channel via a tee pipe. The first on-off valve 4 is used to open the first pipeline 31 or the second pipeline 32, respectively, to control the connection between the first pipeline 31 and the first channel, or to control the connection between the second pipeline 32 and the first channel; thereby controlling the delivery of the hot medium in the first pipeline 31 or the cold medium in the second pipeline 32 into the heat exchange assembly 22 for heat exchange with the cleaning fluid.

[0038] Combine Figure 1The filter assembly 21 includes a filter 211 and a first detection assembly 212. The filter 211 is used to filter the impurities and metal powder in the cleaning liquid. The filter 211 is provided with a liquid inlet pipe 2101 and a liquid outlet pipe 2102. The liquid inlet pipe 2101 and the liquid outlet pipe 2102 are connected to the degreasing tank; the first detection assembly 212 is a pressure sensor, which is used to detect the internal pressure of the filter 211 in real time; during operation, the cleaning liquid in the degreasing tank is transported into the filter 211 through the liquid inlet pipe 2101 for filtration, and after being filtered by the filter 211, it is transported back to the degreasing tank through the liquid outlet pipe 2102 for continued use to ensure that there are no impurities in the cleaning liquid.

[0039] The filter may include a barrel, a barrel cover, and a filter element arranged in the barrel for filtering impurities.

[0040] The second detection component 5 is also included and is disposed in the filtration circuit 10. The second detection component 5 is disposed on the liquid outlet pipe 2102 of the filter 211 and is a temperature sensor for real-time monitoring of the temperature of the cleaning liquid after heat exchange in the heat exchange component 22 and transported back to the degreasing tank.

[0041] The filter 211 also has a second on-off valve 6 on the liquid inlet pipe 2101 and the liquid outlet pipe 2102. The second on-off valve 6 can be a manual on-off valve. When replacing the filter element or repairing the filter 211, the second on-off valve 6 can close the liquid inlet pipe 2101 and the liquid outlet pipe 2102 to prevent the backflow of the cleaning liquid and facilitate maintenance.

[0042] The system further includes a control assembly electrically connected to the first on-off valve 4, the filter assembly 21, and the second detection assembly 5. The control assembly controls the first on-off valve 4 to open the first pipeline 31 or the second pipeline 32 based on an electrical signal fed back by the second detection assembly 5, allowing the hot medium in the first pipeline 31 or the cold medium in the second pipeline 32 to enter the heat exchange assembly 22 for heat exchange with the cleaning fluid, thereby regulating the temperature of the cleaning fluid. When the pressure in the filter 211 is excessive, the first detection assembly 212 feeds back an electrical signal to the control assembly to alert the operator to promptly repair or replace the filter.

[0043] In some embodiments, the filter unit 2 can be provided in plurality, and the filter unit 2 corresponds one-to-one to the degreasing tank, and can independently filter the cleaning liquid in the corresponding degreasing tank to improve the filtration efficiency; the filter unit 2 can be increased or decreased according to actual conditions. In this embodiment, there are two filter units 2.

[0044] Example 2

[0045] Based on Example 1, Example 2 differs from Example 1 in that, when there are at least two filter components 21 (21A, 21B), the filter components 21 (21A, 21B) are arranged side by side in parallel, and the degreasing tank is connected to the two parallel filter components 21 (21A, 21B).

[0046] Combine Figures 2 to 4 In this embodiment, two filter components 21 are taken as an example for explanation. The liquid inlet pipes 2101 of the two filter components 21 are connected to the degreasing tank, wherein the liquid inlet pipes 2101 can be connected to the degreasing tank through a three-way pipe, and the second switch valve 6 is respectively provided on the liquid inlet pipe 2101; the two filter components 21 can work independently; when there are too many impurities in any of the filter components 21, resulting in excessive pressure, the second switch valve 6 can be used to replace the other filter components 21 to work, so that the cleaning liquid can be continuously filtered without stopping the machine.
