Description

Technical Field

[0001] The utility model relates to a device for recovering and disassembling waste filter elements of a wet process line. Background Art

[0002] At present, in the PCB production process, the liquid medicine in each wet process production line needs to be filtered by folded filter elements for liquid medicine circulation. However, due to the high requirements of the wet process production line for liquid medicine, in order to ensure the quality of the liquid medicine, it is often necessary to frequently replace the folded filter element to ensure the filtration quality, which will generate a large number of discarded filter elements, and these filter elements used to filter liquid medicine need to be treated as hazardous waste after being discarded.

[0003] A discarded pleated filter element mainly consists of two parts: the plastic shell and the non-woven fabric used for filtering inside the plastic shell. The non-woven fabric inside actually needs to be treated as hazardous waste, while the plastic shell can be recycled. However, since the non-woven fabric is sealed in the plastic shell, the discarded filter element can only be treated as hazardous waste as a whole when it is processed. This leads to an inflated cost of hazardous waste treatment, and plastics that could have been recycled will also be treated as hazardous waste, which is not conducive to the recycling of plastics and will also increase environmental pressure.

Then, the driving mechanism is started again to press down the horizontal bar 21 above each filter element housing cutting assembly 2, so that the upper and lower horizontal bars 21 are moved closer to each other to merge the cutting grooves, and the outer shells at both ends of the filter element 4 are cut open by the blade 23. In this way, the non-woven fabric inside the filter element 4 can be taken out from both ends of the filter element 4, so that the plastic shell and the non-woven fabric of the filter element 4 can be recycled separately when recycling, and the non-woven fabric is treated as hazardous waste as usual, and the plastic shell can be recycled and reused after cleaning. For filter elements 4 of different lengths, the filter element fixing assembly 3 and the filter element housing cutting assembly 2 on the right side can be moved left and right, so that the distance between the left and right filter element housing cutting assemblies 2 and the position of the filter element fixing assembly 3 can adapt to filter elements of different lengths.

In addition, the disassembly device of this case can also adjust the position of the filter element fixing component 3 and the filter element housing cutting component 2 according to the length of different filter elements, so that the disassembly device of this case can better adapt to filter elements of different lengths and sizes, thereby improving the applicability of the disassembly device of this case.

[0032] like Figures 1 to 3 As shown, preferably, the workbench 1 is provided with an inverted T-shaped guide groove 11 extending left and right and distributed front and back, and the bottom of the filter element fixing assembly 3 and the bottom of the horizontal bar 21 under the right filter element housing cutting assembly 2 are provided with a plurality of inverted T-shaped bosses 12 distributed front and back, and the inverted T-shaped bosses 12 correspond to the positions of the inverted T-shaped guide groove 11 so as to be embedded therein and slide left and right along the inverted T-shaped guide groove 11.

In this way, the two horizontal bars 21 can be driven away from each other to open the cutting groove and close to each other to perform the cutting action through the action of the driving cylinders 5.

[0039] As mentioned above, the disassembly device of this case also includes a water connector 6 and a solid-liquid separation recovery box 7. When cutting the filter element 4, the filter element housing cutting component 2 on the right side can be inactive first.

At the same time, the water flow can also flush and clean the part of the filter element 4 housing that is still on the workbench 1. After the flushing is completed, the filter element housing cutting component 2 on the right side is started again, and the cutting action of the left and right ends of the filter element 4 housing is finally completed.

The separated water can flow into the liquid recovery box 72 through the water outlet of the centrifugal dehydrator 73, which is convenient for unified treatment.

[0043] like Figure 5 As shown, preferably, a circulation pipeline 74 for re-inputting the liquid in the liquid recovery tank 72 to the water channel connector 6 is also connected between the inner cavity of the liquid recovery tank 72 and the water channel connector 6, and a water pump is connected to the circulation pipeline 74. In this way, when the water in the liquid recovery tank 72 meets the cleaning requirements, the water in the liquid recovery tank 72 can be circulated through the circulation pipeline 74 to flush the filter element 4, thereby reducing the consumption of water resources.

The hollow groove 712 can ensure that the water flow will eventually flow into the liquid recovery box 72, and will not accumulate at the lowest point of the inner bottom surface of the solid recovery box 71.

[0047] like Figures 5 to 7As shown, preferably, the solid recovery box 71 is also provided with an opening facing right and the bottom surface of which is flush with the leftmost side of the workbench 1 surface.

[0049] like Figures 1 to 6 As shown, preferably, at least one horizontal bar 21 in each filter element housing cutting assembly 2 is provided with a limit stop bar 211 on the outer side for limiting the end of the filter element 4, so that the filter element 4 can be prevented from slipping out of the filter element housing cutting assembly 2 on both sides before cutting is completed.

[0050] like Figure 4 As shown, preferably, the limit stop bar 211 of the left filter element housing cutting assembly 2 is set at the upper horizontal bar 21, so that the limit stop bar 211 can be prevented from obstructing the left end housing of the filter element 4 and the non-woven fabric from entering the solid-liquid separation recovery box 7 after the cutting is completed.
