Description

Technical Field

[0001] This utility model relates to the field of tailings acidification treatment technology, specifically to a tailings acidification treatment device. Background Technology

[0002] Tailings are the portion of the product from mineral processing that has a low content of the target component and cannot be used for production. Tailings are a treasure trove waiting to be tapped. Experts believe that the current task of my country's mining circular economy is to develop and utilize the large amount of long-term abandoned tailings. Acidification treatment equipment is needed when treating tailings.

[0003] Chinese utility model patent application number CN202022348457.5 discloses a tailings acidification treatment device, which includes an acidification tank, a motor, a partition, and a through hole. The partition is installed inside the acidification tank and is connected to the acidification tank by screws. The advantages are: by setting up a motor, partition, through hole, rotating shaft, and blades, during the operation of the device, the motor drives the rotating shaft to rotate, which in turn drives the blades to stir the sulfuric acid, causing the sulfuric acid to form a swirling flow. The swirling flow then drives the sulfuric acid above the partition to also form a swirling flow, allowing the sulfuric acid to fully contact the tailings, ensuring the acidification effect of the device and improving its practicality. By setting up a guide plate and hydraulic rod, the guide plate can guide the tailings during the feeding process, thus preventing the tailings from impacting the inner wall of the acidification tank. At the same time, the hydraulic rod can drive the large end of the guide plate to move, thus spreading the tailings evenly on the partition, preventing accumulation, and improving the functionality and service life of the device.

[0004] In this structure, although the sulfuric acid is rotated by the blades to form a vortex, the baffle plate prevents the formation of a vortex above the baffle plate by simply opening the through holes. Instead, the sulfuric acid above the baffle plate only tumbles slightly, failing to allow the sulfuric acid to fully contact the tailings. Furthermore, the tailings easily fall into the mixing zone through the through holes, making the mixing zone difficult to clean. In addition, the guide plate that can swing up and down guides the tailings only slightly increases the surface area of ​​the tailings accumulated above the baffle plate, without making the tailings evenly spread above the baffle plate. Utility Model Content

The drive shaft 9 is driven to rotate by an electromagnetic motor 8, thereby causing the stirring blades 9.1 to rotate the sulfuric acid and form a vortex. An inlet 6.1 is opened on the upper side of the sealing cover 6 for feeding tailings into the pickling tank 1. An outlet 1.3 is opened on one side of the pickling tank 1 for discharging the cleaned tailings and facilitating the cleaning of the inside of the pickling tank 1.
