[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 To address the issue that residual liquid in the collection tank continues to drip down after collection, hindering its practicality, the following preferred technical solution is provided:
[0022] A filter press device for acidified residue of PCB ink wastewater includes a filter press body 1. A power unit 2 is installed on one side of the filter press body 1. Multiple sets of filter plates are provided at the output end of the power unit 2. A drain pipe 4 is provided on one side of each set of filter plates. A collection body 5, which is fixedly installed on the outer wall of the filter press body 1, is provided at the end of the drain pipe 4 away from the filter plates. A guide plate 6 is installed at the bottom of the cavity of the collection body 5. A discharge channel 7 is provided at the lowest point of the guide plate 6. The discharge channel 7 is connected to the inner cavity of the collection body 5. A sealing component 8 is installed in the cavity of the discharge channel 7. The sealing component 8 includes components that are slidably connected to the discharge channel. A sliding rod 81 is attached to the inner wall of the unloading channel 7. A middle connecting rod 82 is fixedly connected to the lower end of the sliding rod 81. An upper connecting plate 83 is slidably connected to the outer wall of the middle connecting rod 82. The upper connecting plate 83 is fixedly connected to the inner wall of the unloading channel 7. A lower connecting plate 84 is fixedly connected to the lower end of the middle connecting rod 82. Multiple sets of upper through holes 85 are opened through the upper wall of the upper connecting plate 83. Multiple sets of lower through holes 86 are opened through the upper wall of the lower connecting plate 84. A first elastic component 87 and a second elastic component 88 are respectively installed on both sides of the upper connecting plate 83. The size of the upper connecting plate 83 matches the size of the unloading channel 7. The multiple sets of upper through holes 85 and multiple sets of lower through holes 86 are staggered.
[0023] The first elastic component 87 and the second elastic component 88 have the same structure and are symmetrically distributed about the center of the middle connecting rod 82. The first elastic component 87 comprises an outer connecting rod 871 fixedly connected to the lower connecting plate 84 at one end, and an inner connecting rod 872 fixedly connected to the sliding rod 81 at one end. The inner connecting rod 872 is fixedly connected with a sliding plate body 873 at an end away from the sliding rod 81. The sliding plate body 873 is in sliding connection with the inner wall of the outer connecting rod 871. The lower end of the sliding plate body 873 is fixedly connected with a return spring 874. The end of the return spring 874 away from the sliding plate body 873 is fixedly connected with the bottom of the cavity of the outer connecting rod 871.
[0024] Specifically, when performing the filter pressing operation, the sludge block to be filter pressed is placed directly on the two groups of filter pressing plates. The filter pressing plates are driven by the power body 2 to extrude the sludge block. The extruded sludge liquid is discharged from the liquid discharge pipe 4 to the collecting body 5 for preliminary collection. After the collecting body 5 collects the sludge liquid, the staff places the external collecting device at the lower end of the liquid discharge channel 7. The sludge liquid in the cavity of the collecting body 5 flows to the liquid discharge channel 7 through the flow guide inclined plate 6. After flowing into the liquid discharge channel 7, the sludge liquid is accumulated on the lower connecting plate 84 through the upper through hole 85 of the upper connecting plate 83 and is supported by the first elastic component 87 and the second elastic component 88. After accumulating to a certain weight, the lower connecting plate 84 pulls down the first elastic component 87 and the second elastic component 88, and the lower connecting plate 84 moves away from the upper connecting plate 83. At this time, the sludge liquid flows down through the lower through hole 86, and the staff can complete the collection of the sludge liquid. Then, the first elastic component 87 and the second elastic component 88 drive the lower connecting plate 84 to move upwards, so that the lower connecting plate 84 approaches the upper connecting plate 83 to seal the liquid discharge channel 7, and the sludge liquid cannot drip. The utility model has good practicability and solves the problem of insufficient practicability that the residual sludge liquid in the collecting groove still drips downward after the collection is completed.
[0025] The lower connecting plate 84 pulls down the first elastic component 87 and the second elastic component 88, and the inner connecting rod 872 drives the sliding plate body 873 to pull out the return spring 874. After the staff completes the collection of the sludge liquid, the reaction force of the return spring 874 drives the inner connecting rod 872 to reset, so as to pull back the lower connecting plate 84.
