Description

Technical Field

[0001] The utility model belongs to the technical field of metal extraction, in particular to a novel heavy metal extraction device. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, and refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products lost with water, and pollutants generated in the production process. Industrial wastewater contains a large amount of heavy metal pollutants.

[0003] Existing heavy metal extraction devices generally use chemical electrolysis during use. During the electrolysis process, unstable ions in the waste liquid are separated under the action of electricity and react with special chemical solutions to generate precipitates. The generated metal precipitates will adhere to the inner wall of the extraction device and need to be manually cleaned and extracted, which wastes manpower and reduces efficiency.

[0004] For example, (authorization announcement number CN220098785U) a fly ash washing heavy metal extraction device makes large particles roll to the right to reach the collection box, the solution is initially filtered through the filter, and then the solution reaches the surface of the adsorption plate fixedly connected to the surface of the adsorption rod to adsorb the fine impurities inside the solution. The adsorption rod is driven to rotate by the first motor to accelerate the adsorption effect, so as to achieve multiple filtration of the solution and prevent secondary pollution. This device has this problem: during use, it is impossible to automatically clean and collect the metal precipitates attached to the inside of the device, reducing the use efficiency.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] After the extraction is completed, the top cover of the novel heavy metal extraction device is removed, and the first motor arranged on the vertical side of the installation frame is used to drive the two moving blocks on the outer periphery of the bidirectional screw to move toward each other, so that the moving blocks use the connecting blocks at the top to synchronously drive the plug plate to fit the vertical inner wall of the extraction box for lateral displacement. At the same time, when the plug plate fits the inner wall of the extraction box during displacement, the second motor arranged on the top of the plug plate controls the moving plate on the outer periphery of the screw to move up and down, so that the scrapers on the side of the moving plate scrape off the metal deposits attached to the inner walls of the other two sides of the extraction box.

[0016] Then, the scraped metal deposits are made to fall into the fixed frame, and the screw nail set at the top of the first connecting column is screwed, so that the second connecting column drives the mounting plate and the fixed frame to move downward synchronously, so that the mounting groove no longer blocks the filter screen on the vertical side of the fixed frame, and the extracted liquid flows into the storage box, thereby storing the metal deposits on the fixed frame, so as to facilitate the automatic collection of metal deposits, prevent the metal deposits from adhering to the inner wall of the extraction box, save manpower, do not need manual cleaning, and improve the use efficiency.
