[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 4 The utility model discloses a special ink recovery and processing device for printed circuit boards, comprising three shells 10 distributed up and down, each of which is inlaid with a cylinder 20 integrally connected thereto, a hydraulic cylinder 30 is bolted to the lower inner wall of the lowest cylinder 20, a long rod 40 is installed to the hydraulic rod at the top of the hydraulic cylinder 30, a fixing frame 50 is bolted to the top surface of the highest shell 10, the top of the long rod 40 is bolted and fixedly connected to the fixing frame 50, a plurality of connecting columns 60 are integrally connected to the top surfaces of the two lower shells 10, a plurality of connecting grooves are provided on the bottom surfaces of the two upper shells 10, the connecting columns 60 are slidably connected to the connecting grooves up and down, the outer walls of the two lower cylinders 20 and the inner walls of the two lower shells 10 are integrally connected to support frames 70, and each pair of support frames 70 is clamped and placed with a filter screen plate 80 matching therewith.
[0022] The filter holes of the upper filter screen plate 80 are larger than the filter holes of the lower filter screen plate 80. The upper filter screen plate 80 performs coarse filtering, while the lower filter screen plate 80 performs fine filtering. At the same time, the filter screen plate 80 is composed of two arc-shaped filter screens spliced together, which is convenient for replacement. The cross-sections of the connecting column 60 and the connecting groove are both T-shaped structures, which can prevent the connecting column 60 from being separated from the connecting groove, thereby ensuring that the three shells 10 are equidistantly separated. The uppermost shell 10 is provided with an ink inlet, which is a cylindrical structure. Even if the height of the shell 10 is offset, it will not affect the insertion of the ink inlet tube.
[0023] Specifically, the bottom of the lowest cylinder 20 is sealed, and the upper and lower ends of the other two cylinders 20 are open. The bottom end of the lowest shell 10 is provided with an ink outlet 100, and the lower inner wall of the lowest shell 10 is provided with a plurality of connection holes 110 connected to the ink outlet 100.
[0024] In this embodiment, it plays a role in discharging ink without affecting the installation of the hydraulic cylinder 30 .
[0025] Specifically, the two lower cylinders 20 are both screwed with the limiting frames 90 , and the long rod 40 passes through the limiting frames 90 .
[0026] In this embodiment, the long rod 40 is connected to the limiting frame 90 in an up-and-down sliding manner, which can guide the long rod 40 , and the long rod 40 has high stability when sliding up and down.
[0027] Specifically, a first frame-type nozzle 200 is fixedly installed on the top surface of the two lower shells 10, and a frame-type groove matching the first frame-type nozzle 200 is opened on the bottom surface of the two upper shells 10. A second frame-type nozzle is installed on the inner wall of the uppermost shell 10, and a three-channel water inlet hose 210 is connected between the two first frame-type nozzles 200 and one second frame-type nozzle. The water outlet holes on the first frame-type nozzle 200 are tilted downward, and the water outlet holes on the second frame-type nozzle are tilted upward, horizontal, and tilted downward from top to bottom, respectively. An extended pressure frame 220 is integrally connected to the lower part of the inner walls of the two upper shells 10.
[0028] In the present embodiment, the first frame-type nozzle 200 and the second frame-type nozzle can realize flushing of the inner wall of the shell 10, and the flushing is uniform and convenient. In normal use, even if the first frame-type nozzle 200 is located at a lower position, it will not come into contact with the ink, and has high safety. The setting of the extended pressure frame 220 has two functions. One is that it can squeeze the filter screen plate 80 to improve the stability of the filter screen plate 80 after the snap-on installation, and the other is that after the shell 10 is opened again, a small amount of ink on the inner wall of the shell 10 will not leak out.
[0029] The working principle and use process of the utility model are as follows: during normal use, the ink used for the recycled printed circuit board enters the shell 10 through the ink inlet on the uppermost shell 10, first passes through the coarse filtration of the upper filter screen plate 80, and then passes through the fine filtration of the lower filter screen plate 80, and is discharged from the ink outlet 100 through the connecting hole 110; when the filter screen plate 80 needs to be replaced, the hydraulic cylinder 30 is started to drive the long rod 40 to move upward, and the uppermost shell 10 is first separated from the middle shell 10. When the gap cannot be further increased, the middle shell 10 and the lowermost shell 10 begin to separate until the gap cannot be further increased. At this time, the three shells 10 all maintain a spacing, and the filter screen plate 80 can be directly taken out from the support frame 70 (take out half and half). If it is necessary to rinse the inner wall of the shell 10, the cleaning liquid can be delivered to the three-channel water inlet hose 210 at this time. At this time, the first frame-type nozzle 200 and the second frame-type nozzle both spray cleaning liquid to achieve cleaning of the inside of the shell 10, which is convenient and clean.
