Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater heavy metal treatment device. Background Art

[0002] Industrial wastewater contains a large amount of heavy metals. The treatment of heavy metals in industrial wastewater is a vital environmental protection measure aimed at reducing or eliminating toxic heavy metal elements in wastewater, thereby protecting water resources from pollution.

[0003] Currently available industrial wastewater heavy metal treatment devices usually transport industrial wastewater containing heavy metals to the treatment equipment, add alkaline substances or sulfide reagents to the wastewater to precipitate the heavy metals, and then remove them through precipitation separation technology; or use activated carbon, zeolite, resin or other adsorption materials to remove heavy metal ions in the wastewater. However, the treatment methods of existing devices are mostly relatively simple, resulting in insufficient treatment effects.

[0004] Therefore, in order to solve the above problems, an industrial wastewater heavy metal treatment device has been developed, which can simultaneously use physical and chemical methods to dual-treat wastewater and improve the treatment effect. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices that most of the treatment methods are relatively single, resulting in insufficient treatment effects, the utility model provides an industrial wastewater heavy metal treatment device that can simultaneously use physical and chemical methods to dual-treat wastewater to improve the treatment effect.

[0006] The technical scheme is as follows: An industrial wastewater heavy metal treatment device comprises a treatment box, a filter plate, a support block, an adsorption box, a support plate, a protective frame, a fixed frame, a motor, a gear set and a stirring frame. The upper part of the treatment box is connected with a support block, and a filter plate is clamped above the support block. The upper middle part of the treatment box is slidably connected with the adsorption box, and the middle part of the treatment box is symmetrically connected with the support plate. The left side of the lower part of the treatment box is connected with a protective frame, and the left side of the protective frame is connected with a fixed frame. The fixed frame is connected with a motor, and the lower part of the treatment box is rotatably connected with a plurality of stirring frames. A gear set is connected between the stirring frame and the motor output shaft, and the gear set is located inside the protective frame. The adsorption material is placed through the adsorption box. In the process of industrial wastewater being transported to the treatment box, large particles of impurities are first filtered through the filter plate, and then the heavy metals in the wastewater are preliminarily adsorbed and removed by the adsorption material in the adsorption box. Then, chemical agents are added to the treatment box, and the motor output shaft rotates through the gear set to drive the stirring frame to rotate, so that the chemical agents and the wastewater are evenly mixed, and the heavy metals are secondary precipitated and removed.

[0007] Optionally, supporting feet are also included, and the lower sides of the left and right parts of the processing box are symmetrically connected to the supporting feet front and back.

[0008] Optionally, it also includes fixed blocks and electric push rods. Multiple fixed blocks are connected to the front side of the upper part of the processing box. Electric push rods are connected between the fixed blocks. The telescopic end of the electric push rod is connected to the filter plate. The filter plate is driven to move upward by the telescopic end of the electric push rod, thereby facilitating the removal of the filter plate.

[0009] Optionally, a handle is provided on the left side of the adsorption box.

[0010] Optionally, a rotating plate is also included. The right part of the treatment box is rotatably connected to the rotating plate. The rotating plate can be used to isolate the wastewater in the treatment box to avoid splashing of the wastewater during the treatment process.

[0011] Optionally, a water outlet pipe is also included, and the front side of the lower right part of the treatment box is connected with the water outlet pipe to facilitate the discharge of the treated wastewater in the treatment box.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model performs preliminary adsorption and removal of heavy metals in wastewater by the adsorption material in the adsorption box, and then adds chemical agents into the treatment box to make the chemical agents react with the heavy metals to perform secondary precipitation and removal of the heavy metals. The wastewater can be treated by both physical and chemical methods at the same time, thereby improving the treatment effect.

[0013] 2. The utility model controls the gear set through the motor to drive the stirring frame to rotate. The stirring frame rotates to stir the wastewater and chemical agents in the treatment box, which can make it easier to mix the chemical agents and wastewater evenly and improve the chemical reaction efficiency.
