Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an electroplating wastewater treatment device. Background Technology

[0002] With the continuous development of industrial technology, electroplating technology has been widely used in industrial production. Electroplating processes often generate a large amount of electroplating wastewater. The quality and quantity of electroplating wastewater are related to factors such as the process conditions, production load, operation management, and water usage of electroplating production. The quality of electroplating wastewater is complex, and the cyanide ions in it are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. They must be treated by treatment equipment to ensure that their content meets the standards before wastewater can be discharged.

[0003] Chinese Patent Publication No. CN219058583U, published on May 23, 2023, discloses an electroplating wastewater treatment device, including a treatment tank; a stirring mechanism is installed inside the treatment tank, a treatment mechanism is installed on one side inside the treatment tank, and an auxiliary mechanism is installed on one side of the treatment tank. The treatment mechanism includes a fixed base, a treatment cylinder, and a fixed port, and a fixed base is installed inside the fixed port.

[0004] Existing electroplating wastewater treatment devices, such as those described above, have a treatment mechanism installed on one side inside the treatment tank. Personnel transport external electroplating wastewater into the treatment tank, where impurities are isolated. The treated wastewater then flows out of the tank, preventing impurities from settling at the bottom. However, in practice, subsequent centralized treatment of impurities requires pulling the treatment tank upwards, which is inconvenient. Furthermore, if the collection tank is not fully filled, impurities inside can easily adsorb catalysts discharged from the placement tank, hindering the normal treatment of electroplating wastewater. Therefore, there is an urgent need to develop a corresponding electroplating wastewater treatment device to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electroplating wastewater treatment device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electroplating wastewater treatment device includes a support frame. A treatment tank and a detection tank are fixedly connected to the top of the support frame, and the inner cavities of the treatment tank and the detection tank are connected by a pump body. The top of the treatment tank integrates a water inlet and a placement tank. A screen seat is provided below the water inlet and fixedly connected to the inner wall of the treatment tank. A stirring assembly is integrated inside the treatment tank. A dirt removal port is opened on the outer side of the treatment tank near the open end of the screen seat. A collection drawer is detachably connected to the bottom of the dirt guide seat.

[0008] Preferably, the stirring assembly includes a driving component fixedly connected to the bottom of the processing tank, and a stirring rod is fixedly connected to the output end of the driving component.

[0009] Preferably, an outer connecting plate is fixedly connected to the outer wall of the vertical end of the sieve seat, and the bottom plate of the outer connecting plate is rotatably connected to the top of the stirring rod.

[0010] Preferably, a tab is fixedly connected to the outer wall of the guide seat, and the tab is fixedly connected to the collection drawer by a locking rod.

[0011] Preferably, a base is fixedly connected to the outer wall of the processing box, and the top of the base abuts against the bottom of the collection drawer.

[0012] Preferably, the base is fixedly connected to the outer wall of the processing box via a return pipe, and the base, the return pipe and the inner cavity of the processing box are in communication. The return pipe has an integrated check valve, and the bottom of the collection drawer is hollowed out.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, water is introduced into the treatment tank through the inlet. Solid impurities in the wastewater are isolated by the screen seat. The solid impurities are guided along the bottom of the inclined screen seat to the impurity guide seat until they enter the collection tray. The screened water is then placed in the treatment tank, and a corresponding amount of catalyst is discharged from the tank. The drive unit drives the stirring rod to rotate to mix the wastewater and the catalyst. Then, the wastewater is guided to the detection tank by the pump body, and finally discharged through the outlet. In this way, while ensuring the normal treatment of electroplating wastewater, the collection tray is integrated on the outside of the treatment tank, which ensures the convenience of centralized treatment of impurities, and the impurities will not affect the mixing of wastewater and catalyst.

[0015] 2. In this application, an external connecting plate is fixedly and horizontally installed on the outside of the screen base, and the bottom of the external connecting plate is rotatably engaged with the top of the stirring rod, thereby avoiding eccentric misalignment of the stirring rod and ensuring the stability of the stirring rod rotation, thus ensuring the stability of the electroplating wastewater treatment device.
