Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment, in particular to a dosing device for electroplating wastewater treatment. Background Art

[0002] The wastewater and waste liquid discharged from electroplating factories contain a large amount of metal ions such as chromium, iron, nickel, cyanide, acid, alkali and other substances, which are basically removed by chemical precipitation. Therefore, a dosing device is needed to add chemicals to neutralize some substances in the wastewater.

[0003] According to the authorization announcement number CN216273185U, a multi-point dosing device for electroplating wastewater treatment is disclosed. The device relates to the technical field of electroplating wastewater treatment and includes: a drug storage box; multiple legs spaced apart and installed below the drug storage box; a wastewater treatment box disposed below the drug storage box, with the upper surface of the wastewater treatment box connected to the bottom of the legs; a dosing pump connected and installed at the bottom of the drug storage box; a drug outlet pipe connected to the bottom of the dosing pump; an extension pipe fitted onto the drug outlet pipe and extending into the interior of the wastewater treatment box; a multi-way pipe assembled at the bottom of the extension pipe; multiple drug outlet nozzles, each connected and installed at the bottom of the multi-way pipe; and an adjustment mechanism mounted on both sides of the drug storage box, with the bottom of the adjustment mechanism passing through the wastewater treatment box and connected to the multi-way pipe. This utility model solves the technical problem of the limited drug discharge range of dosing equipment in the prior art.

[0004] Although the above scheme can expand the range of drug discharge and evenly disperse the drugs in the wastewater treatment tank by moving the multi-way pipe up and down in the wastewater treatment tank, it cannot evenly spray the drugs in the horizontal direction. When the treatment tank is long, its applicability is low. For this reason, we propose a dosing equipment for electroplating wastewater treatment. Utility Model Content

[0005] The main purpose of the utility model is to provide a dosing device for electroplating wastewater treatment, which solves the problem of not being able to spray medicine evenly in the horizontal direction when the treatment box is long by setting an adjustment unit and a dosing unit.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The adjustment unit includes a fixing seat mounted on the side wall of the main unit, a fixing groove provided on the side wall of the fixing seat, a threaded shaft movably mounted in the fixing groove, a moving member mounted on the circumferential side of the threaded shaft, and a first driving motor mounted on the input end of the threaded shaft;

[0009] The dosing unit includes an electric push cylinder installed on the side wall of the moving part, a medicine storage box installed on the telescopic end of the electric push cylinder, and a dosing piece arranged at the bottom of the medicine storage box.

[0010] Preferably, the main unit includes a wastewater treatment tank and a discharge member provided on a side of the wastewater treatment tank.

[0011] Preferably, the discharge member includes a discharge pipe opened on the side wall of the wastewater treatment tank, and an opening and closing valve movably installed on the side wall of the discharge pipe.

[0012] Preferably, the adjustment unit further includes a limiting washer installed on the inner side wall of the fixing groove, and the limiting washer is sleeved on the circumferential side surface of the threaded shaft.

[0013] Preferably, the dosing member includes a dosing pipe opened at the bottom of the medicine storage box, and a regulating valve movably installed inside the dosing pipe.

[0014] Preferably, the stirring unit includes a fixed plate installed on the opposite side walls of the medicine storage box, a rotating shaft movably installed at the bottom of the fixed plate, a stirring rod installed on the side wall of the rotating shaft, a second drive motor installed at the input end of one of the rotating shafts, and a transmission member arranged between the two rotating shafts.

[0015] Preferably, the transmission member includes a pulley mounted on a side wall of the rotating shaft, and a transmission belt movably mounted between two of the pulleys.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the utility model, through the setting of the regulating unit and the dosing unit, when it is necessary to evenly disperse the medicine in the wastewater treatment box, the regulating valve is opened to discharge the medicine in the medicine storage box from the discharge pipe. Subsequently, the first drive motor drives the threaded shaft to rotate, so that the moving part drives the medicine storage box to move along the threaded shaft, thereby realizing uniform spraying of medicine in the horizontal direction. While the medicine storage box moves along the threaded shaft, the telescopic end of the electric push cylinder is extended and retracted, driving the medicine storage box to move up and down in the vertical direction, thereby realizing uniform spraying of medicine in the vertical and horizontal directions, thereby improving the applicability of the equipment; while uniformly spraying the medicine, the second drive motor drives one rotating shaft to rotate, and drives another rotating shaft to rotate synchronously through the pulley and the pulley. When the rotating shaft drives the stirring rod to rotate, the precipitated medicine solution and the wastewater can be fully mixed, thereby improving the treatment effect of the electroplating wastewater.
