DETAILED DESCRIPTION

[0025] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0026] like Figure 1-Figure 7 As shown, a coating tank for electrophoretic ultrafiltration includes a bracket 1 and a tank structure 2 installed on the bracket 1; a filter tube 3 is provided in the tank structure 2, and a drainage surface 4 for draining liquid to the filter tube 3 is provided on the top of the tank structure 2; a spray pipe 11 is installed on the tank structure 2 to spray to the drainage surface 4, a filter screen 5 is installed on the top of the filter tube 3, and a liquid outlet connected to the tank structure 2 is formed at the bottom of the filter tube 3; a filter plate 6 is installed in the tank structure 2, and a sewage outlet 15 and a suction port 14 are formed at the bottom of the tank structure 2 on both sides of the filter plate 6, and the sewage outlet 15 and the filter tube 3 are located on the same side of the filter plate 6.

[0027] Under the action of the bracket 1, the trough structure 2 is overhead, the filter tube 3 is vertically arranged, the liquid to be filtered is discharged through the spray pipe 11, and flows on the surface of the drainage surface 4 under the action of the liquid's own gravity. The liquid entering the filter tube 3 is filtered under the action of the filter mesh 5, and the filter plate 6 is used to filter the liquid in the trough structure 2. The filtered liquid is discharged through the sewage outlet 15 and the suction port 14 respectively.

[0028] The drainage surface 4 is a funnel-shaped structure that slopes downward from the outside to the inside. The top of the filter tube 3 is located in the middle of the drainage surface 4. Under the action of the drainage surface 4 with a funnel-shaped structure, the liquid sprayed onto the drainage surface 4 flows to the low point of the drainage surface 4 under the action of its own gravity. The lowest point of the drainage surface 4 is located in the middle of the drainage surface 4, so the liquid can be drained to the top of the filter tube 3.

[0029] The suction port 14 is used to connect a water pump to realize the flow of liquid in the tank structure 2 under the action of the water pump, and at the same time ensure that under the action of the suction port 14, the liquid in the tank structure 2 must be filtered by the filter plate 6, thereby achieving a secondary filtration effect on the liquid.

[0030] The filter screen 5 is installed in the middle of the drainage surface 4. The filter screen 5 is arranged corresponding to the top of the filter tube 3. Under the action of the filter screen 5, the liquid entering the filter tube 3 is filtered to achieve preliminary filtration of the liquid.

[0031] The spray pipe 11 includes a connected spray horizontal pipe 12 and a spray vertical pipe 13 . The spray horizontal pipe 12 is installed on the trough structure 2 . The spray vertical pipe 13 is vertically arranged, and the top of the spray vertical pipe 13 is located above the drainage surface 4 .

[0032] A spray head is formed at the top of the spray vertical pipe 13, and the spray horizontal pipe 12 is connected to the water pump to apply a certain pressure to the liquid, thereby ensuring the spraying effect of the spray head. Under the spraying action of the liquid, the liquid can be sprayed in an extended manner to the surface of the drainage surface 4.

[0033] The bottom of the tank structure 2 is tilted, and the filter plate 6 is tilted inside the tank structure 2. The liquid entering the tank structure 2 is facilitated to achieve stratification under the action of the tilted tank structure 2 due to the different densities of the liquid.

[0034] The bottom of the tank structure 2 is tilted downward toward the sewage outlet 15. The sewage outlet 15 is the lowest point of the entire tank structure 2, which facilitates sewage discharge.

[0035] A cover plate 7 corresponding to the filter plate 6 is installed on the top of the tank structure 2, and the filter plate 6 is inclined from top to bottom toward the sewage outlet 15.

[0036] A rim structure 21 is formed on the top of the trough structure 2 and is hung on the bracket 1 . A connecting square tube 17 is provided on the top of the bracket 1 and is engaged with the rim structure 21 . The rim structure 21 is formed on opposite sides of the trough structure 2 .

[0037] Under the action of the edging structure 21, the trough structure 2 can be hung on the bracket 1. At the same time, under the action of the connecting square tube 17, the hanging area of ​​the trough structure 2 is increased to ensure the hanging stability.

[0038] An anti-overflow port 16 is formed on the tank structure 2 to prevent liquid from overflowing. When the liquid level in the tank structure 2 reaches a certain height, the liquid can be discharged from the anti-overflow port 16 to prevent the liquid from overflowing from the top of the tank structure 2.

[0039] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention.
