[0015] 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.

[0016] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1:

[0019] The following is combined with Figure 1-3 The present embodiment describes a micro-electrolysis device for treating dye wastewater, comprising: an electrolytic tower 1, wherein the electrolytic tower 1 is filled with liquid from the top and discharged from the bottom, wherein a circular chamber 2 is provided in the middle of the electrolytic tower 1, wherein a rotating shaft 3 is rotatably connected to the side wall of the electrolytic tower 1 at the axis of the circular chamber 2, wherein the rotating shaft 3 is connected to a servo motor, wherein the other end of the rotating shaft 3 is connected to a packing chamber 4, wherein the packing chamber 4 is filled with electrolytic packing, wherein two opposite sides of the packing chamber 4 are filter structures 5, wherein the aperture of the filter structure 5 is smaller than the particle size of the packing;

[0020] The filtered dye wastewater is injected from the upper part of the electrolytic tower 1, and the wastewater passes through the filter screen structure 5 into the interior of the packing chamber 4. Since the packing particle size is relatively dense between 10-20 μm, the wastewater flows slowly and is electrolyzed and decolorized while flowing, and is discharged through the lower filter screen structure 5. Some condensates in the wastewater adhere to the surface of the upper packing and affect the electrolytic performance. At this time, the servo motor controls the packing chamber 4 to rotate 180 degrees, the lower clean packing flips to the upper part, and the condensates flip to the bottom layer. The wastewater after electrolysis carries the condensates through the lower filter screen structure 5 to clean the packing. The packing is flipped back and forth at a lower frequency, which protects the packing particle size and makes full use of each layer of packing.

[0021] Two water inlet and outlet holes 6 are provided on both sides of the arc surface of the circular chamber 2, one of which is connected to a liquid inlet pipe 7;

[0022] Instead of using the wastewater after electrolysis for cleaning, the packing chamber 4 is turned 90°, the packing with condensate is located on the other side of the liquid inlet pipe 7, clean water enters through the liquid inlet pipe 7 to flush the packing, and is discharged through the water inlet and outlet holes 6 on the other side, thereby completing the packing cleaning and preventing the attached matter from being mixed with the wastewater after electrolysis.

[0023] The two ends of the filter structure 5 are connected to the two side walls of the packing chamber 4, and a filling port 8 is left between the other two ends of the filter structure 5 and the other two side walls of the packing chamber 4. The side wall of the electrolytic tower 1 at the filling port 8 is connected to a screw feeder 9;

[0024] The filler will be lost, and the filling machine injects the filler into the filling chamber 4 through the filling port 8 by the rotary feeder 9.

[0025] The filling chamber 4 at the filling port 8 is provided with an inner chamfer;

[0026] The setting of the inner chamfer prevents material from getting stuck at the filling port 8 .

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
