The utility model can improve the treatment effect of electroplating wastewater.

[0004] Although the above patent can filter the flocculated impurities through the filter cartridge, when the filter cartridge needs to be removed from the placement rack to clean the impurities, since the filter cartridge has no structure in the placement rack that is convenient for the hand to lift, the hand needs to support the inner wall of the filter cartridge and apply upward force to remove the filter cartridge during the removal process. The impurities accumulated in the filter cartridge have a certain weight, which increases the difficulty of removing the filter cartridge from the placement rack by hand. Utility Model Content

[0005] The purpose of the utility model is to provide an electroplating wastewater treatment device in view of the defects and shortcomings of the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an electroplating wastewater treatment equipment, comprising a filter tank, a mounting frame arranged on the filter tank, a placement frame arranged on the mounting frame, a filter cartridge which is liftable and arranged on the placement frame, and also comprising an extension portion arranged on the upper end surface of the filter cartridge and located on the peripheral side of the filter cartridge, a countersunk groove opened on the placement frame and gapped with the extension portion, a compression spring arranged between the placement frame and the lower end of the filter cartridge for pushing the filter cartridge to rise on the placement frame, and a limiting device arranged between the upper end surface of the placement frame and the extension portion for limiting the filter cartridge from rising upward after the extension portion and the countersunk groove gap match.

[0007] A further improvement is that the limiting device includes two rotating columns rotatably arranged on the upper end surface of the placement rack and located on the left and right sides of the countersunk groove, and limiting plates respectively arranged on the two rotating columns, and the two rotating columns are symmetrically arranged on the left and right sides of the countersunk groove.

[0008] A further improvement is that the lower end surface of the placement rack is located at the lower end of the compression spring and is a solid part, and the lower end of the filter cartridge is located at the upper end of the compression spring and is a solid part.

[0009] A further improvement is that: the lower end surface of the filter cartridge is provided with a plurality of drainage holes, the drainage holes are eccentrically arranged on the lower end surface of the filter cartridge, and the plurality of drainage holes are equidistantly arranged in a ring shape.

[0010] A further improvement is that a filter screen or filter membrane for separating flocculated impurities and water is provided in each drain hole of the filter cartridge.

[0011] A further improvement is that the filter screen is a nylon filter screen.

[0012] A further improvement is that the filter membrane is an ultrafiltration membrane.

[0013] After adopting the above technical solution, the beneficial effect of the utility model is as follows: when the filter cartridge needs to be taken out from the placement rack to clean the impurities, the limit device is used to release the upward restriction of the extension part. At this time, the compression spring releases the elastic potential energy to push the filter cartridge up in the placement rack, so that the extension part is located above the placement rack. The worker can take out the filter cartridge by holding the extension part with his hand. Although the impurities accumulated in the filter cartridge have a certain weight, the extension part can be moved upward a distance to allow the hand to hold the extension part, thereby improving the convenience of taking the filter cartridge out from the placement rack.

[0014] Further effect: When the compression spring releases its elastic potential energy to push the filter cartridge up in the placement rack, the filter cartridge can be manually pressed down and then the downward pressure is removed, so that the filter cartridge forms a continuous up and down movement in the placement rack. In this process, part of the water in the flocculated impurities can be separated, and the separated water is discharged downward from the drain hole or the hole on the filter cartridge, thereby achieving the purpose of draining.

[0015] Further effect: the filter screen or filter membrane can separate the flocculated impurities and water when the impurities are drained through the drain hole, thereby preventing the flocculated impurities from leaking downward from the drain hole. BRIEF DESCRIPTION OF THE DRAWINGS
