Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electroplating wastewater treatment, in particular to an electroplating wastewater treatment equipment. BACKGROUND

[0002] Electroplating is a common industrial production process, which uses the principle of electrolysis to plate a layer of other metal on the surface of a metal. A large amount of wastewater is generated during the electroplating process, mainly from plating piece cleaning water and waste electroplating solution. Due to the complex water quality and uncontrollable composition of electroplating wastewater, it contains a small amount of organic matter in addition to heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold and silver. Electroplating wastewater poses a risk of causing cancer, teratogenicity and other hazards to human health, and also harms the environment. Therefore, electroplating wastewater must be treated before being discharged.

[0003] Currently, the commonly used electroplating wastewater treatment mainly adopts chemical treatment method, which removes harmful substances in electroplating wastewater by mixing reagents with electroplating wastewater and reacting. However, most of the existing chemical treatment methods directly add reaction reagents. This method mainly relies on the self-dissolution and diffusion of reagents to react with wastewater. However, the self-dissolution and diffusion of reagents takes a long time, and the diffusion range of reagents is limited. The electroplating wastewater at different positions in the reaction tank cannot react with the reagents in time, which reduces the reaction efficiency between the wastewater and the chemical reagents, and thus reduces the purification efficiency of the wastewater, which has obvious shortcomings. CONTENT OF THE INVENTION

[0005] The electroplating wastewater treatment equipment provided by the present application adopts the following technical scheme:

[0006] An electroplating wastewater treatment equipment, comprising a mounting frame, a treatment box is arranged on the mounting frame, a drain pipe is arranged at the bottom of the treatment box, a stirring assembly is arranged in the treatment box, the stirring assembly comprises a stirring motor arranged at the top of the treatment box, an output shaft of the stirring motor is provided with a rotating shaft, the rotating shaft is rotatably connected to the center of the treatment box, opposite sides of the rotating shaft are both provided with a rotating disc, a plurality of stirring rods are uniformly arranged on the rotating disc in a circumferential direction, and a driving assembly for driving the rotating disc to rotate is arranged on the rotating shaft.

[0007] By adopting the above technical scheme, after adding the medicament into the treatment box, the sewage is introduced into the treatment box, and then the stirring motor is started.

Under the stirring of the stirring rods, the diffusion speed of the medicament in the sewage is accelerated. At the same time, the driving assembly drives the rotating disc to rotate. At this time, the plurality of stirring rods rotates around the center of the rotating disc. The plurality of stirring rods generates horizontal and vertical displacement in the rotating process, thereby realizing omnidirectional stirring of the medicament and the sewage in the treatment box. The sewage at different parts of the treatment box can fully react with the medicament. The setting of the stirring assembly and the driving assembly realizes omnidirectional stirring in the treatment box, improves the reaction efficiency of the sewage and the chemical medicament, and thereby improves the treatment efficiency of the sewage.

The rotating shaft drives the driving rod on the rotating disc to revolve around the axis of the treatment box. Since the driving column is fixed in the treatment box, when the driving rod rotates, the gear rolls on the surface of the gear ring. The gear ring drives the gear to rotate around the axis of the driving rod. The rotation of the gear drives the rotating disc of the driving rod to rotate around the driving rod.

[0015] By adopting the above technical scheme, in the process of the rotation of the conveying shaft, the large-particle impurities gradually accumulate under the pushing of the spiral conveying plate and generate a certain pressure on the blowoff plate, when the pressure is greater than the elastic force of the first spring, the large-particle impurities push the blowoff plate to gradually separate from the blowdown opening, the opening degree of the blowdown opening gradually increases, the large-particle impurities are discharged from the blowdown opening, the discharging is realized, with the discharge of the large-particle impurities, the pressure generated by the large-particle impurities on the blowoff plate decreases, the blowoff plate is pushed by the first spring to block the blowdown opening again, and the arrangement of the blowdown assembly realizes the automatic removal of the large-particle impurities, avoids the blowdown opening from being frequently opened and closed manually, and thus the treatment efficiency of the sewage is further improved.
