Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal filtration of industrial wastewater, in particular to a heavy metal filtration and extraction device for industrial wastewater. Background Art

[0002] Heavy metal ions in industrial wastewater are harmful to the environment and human health, so effective measures need to be taken to filter and extract them. Commonly used heavy metal filtration and extraction methods include physical methods, chemical methods, biological methods and adsorption methods. Physical methods mainly include precipitation and filtration methods. The filtration method is to intercept heavy metal ions in the filter through filter media (such as filter cloth, filter membrane, etc.), thereby achieving separation;

[0003] For example, in the prior art, a Chinese patent with a patent publication number of CN217351041U discloses a heavy metal filtration and extraction device for industrial wastewater, which can extract heavy metals in wastewater without discharging wastewater, thereby improving the wastewater filtration effect and avoiding certain pollution to the environment. Secondly, the heavy metals on the surface of the filter plate can be quickly collected, thereby reducing the trouble of extracting heavy metals, improving the efficiency of extracting heavy metals, and further improving the practicality of the heavy metal filtration and extraction device;

[0004] However, after the device filters the heavy metals in the wastewater, it cannot ensure that the incoming water dries quickly. The filtered heavy metals adsorb more wastewater, which affects the collection of the filtered heavy metals. In addition, the wastewater contained in the heavy metals also contains substances that pollute the environment. When the wastewater evaporates naturally, it will pollute the environment. Therefore, a heavy metal filtering and extraction device for industrial wastewater is designed to solve the above problems. Utility Model Content

[0008] The scraper assembly includes a second collar, a positioning bolt and an L-shaped scraper. The second collar is sleeved on the vertical rod. The right side of the second collar is threadedly connected with the positioning bolt, and the left side of the second collar is fixedly provided with an L-shaped scraper.

[0009] Preferably, the diameter of the filter mesh ring is smaller than the inner diameter of the box body, and when the electric telescopic rod is extended to the maximum length, the filter mesh ring is completely extended into the inner side of the box body.
