Description

Technical Field

[0001] This utility model relates to a treatment device, specifically an industrial heavy metal wastewater treatment device. Background Technology

[0002] Heavy metal wastewater is a common pollutant in industrial production processes. This wastewater contains various harmful heavy metal ions, such as lead, cadmium, and mercury. These heavy metals not only have a significant impact on the environment but also pose a serious threat to human health. Therefore, how to effectively treat industrial heavy metal wastewater has become an important issue for environmental protection and sustainable industrial development.

[0003] Traditional filtration devices are often unable to effectively intercept large particles in wastewater, which increases the burden on subsequent treatment processes and affects the overall treatment effect.

[0004] Conventional neutralization devices lack effective stirring and mixing methods, resulting in insufficient contact between wastewater and neutralizing agent, leading to low neutralization reaction efficiency and poor treatment effect. Utility Model Content

Detailed Implementation

[0030] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0031] like Figures 1-4 As shown, the present invention provides an industrial heavy metal wastewater treatment device, comprising:

[0032] The device body 1 has a hollow interior forming a processing cavity 4, and a cover plate 5 is provided on the top of the device body 1. The cover plate 5 is connected to the device body 1 by an electric telescopic rod 6. The cover plate 5 and the device body 1 are sealed by retracting the electric telescopic rod 6.

[0033] The filter device is located at the bottom of the cover plate 5. When the cover plate 5 is placed on the main body 1, the filter device is placed in the processing chamber 4 of the main body 1.

[0034] Neutralization device 3 is rotatably disposed at the bottom of processing chamber 4 and driven by a rotary motor 18 installed at the bottom of device body 1.

[0035] The filter device includes a filter base 7 and a connecting base;

[0036] The connecting seat is fixed to the bottom of the cover plate 5, and the connecting seat and the filter seat 7 are fixed by a threaded connection; the bottom of the filter seat 7 is provided with a filter mesh 9, through which large particles in industrial heavy metal wastewater are filtered. When the cover plate 5 is in the open state, the filter seat 7 can be disassembled and then cleaned.

[0037] The neutralization device includes a rotating rod 10 and a rotary structure disposed at the center of the rotating rod 10;

[0038] The upper and lower ends of the rotating rod 10 are provided with stirring blades 11, and the rotary structure is also provided with stirring blades 11; the connecting end of the rotating rod 10 passes through the main body 1 of the device and is connected to the rotary motor.

[0039] The rotary structure includes a torsion spring 12 disposed at the center of the rotating rod 10 and a rotating block 13;

[0040] The rotating block 13 is rotatably fixed to the torsion spring 12, and the stirring blade 11 is fixed to the rotating block 13. When the rotating motor rotates, the rotating block 13 drives the rotating blade to rotate. After the rotating motor stops, it can continue to rotate for a period of time, thereby further improving the efficiency and effect of neutralization.

[0041] The cover plate 5 has a wastewater inlet pipe 14 at its top, which corresponds to the position of the filter seat 7. A water inlet valve is installed at the wastewater inlet pipe 14. The main body 1 of the device has a neutralizing liquid inlet pipe 15, which is connected to the treatment chamber 4. A liquid inlet valve is installed at the neutralizing liquid inlet pipe 15 to facilitate the precise addition of wastewater and neutralizing agent. The bottom of the main body 1 of the device has a liquid outlet pipe, which is connected to the treatment chamber 4. A liquid outlet valve is installed on the liquid outlet pipe to facilitate the smooth discharge of treated wastewater.

[0042] In addition, it includes a control panel, which connects to control the electric telescopic rod 6, the rotary motor, the water inlet valve, the liquid inlet valve, and the liquid outlet valve to operate; it can remotely control the on / off status of the electric telescopic rod, the rotary motor, and each valve.

[0044] In this invention, wastewater first passes through a filter device located at the bottom of the cover plate. The filter mesh at the bottom effectively traps large particles in the industrial heavy metal wastewater, preventing these particles from entering the treatment chamber and affecting subsequent treatment processes. After the wastewater enters the treatment chamber, the neutralizing liquid enters the treatment chamber through the neutralizing liquid inlet pipe on the main body of the device. The inlet valve controls the amount of neutralizing liquid added, ensuring precise mixing of the wastewater and the neutralizing agent. The neutralizing device located at the bottom of the main body of the device further treats the wastewater, ensuring thorough mixing of the wastewater and the neutralizing agent and guaranteeing a complete neutralization reaction. The treated wastewater is then discharged through the outlet pipe at the bottom of the main body of the device. The outlet valve ensures smooth discharge of the wastewater and prevents liquid accumulation inside the equipment.
