Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal equipment, and in particular to a device for removing impurities from recovered liquid. Background Technology

[0002] Recovery liquid impurity removal equipment is used to treat various recovery liquids to remove solid impurities, suspended solids, colloids and other pollutants contained therein, thereby improving the purity and quality of the recovery liquid so that it can meet the requirements of subsequent processes or meet emission standards.

[0003] Common impurity removal equipment often uses centrifugation to separate the recovered liquid into solid and liquid components, thereby removing impurities. However, some impurities in the liquid are small in diameter and are easily carried out with the liquid during centrifugation. They can only be removed by secondary filtration using filtration equipment, which is quite cumbersome.

[0004] Therefore, we propose a device for removing impurities from recycled liquid to solve the above problems. Utility Model Content

[0026] In this embodiment, a valve seat 9 is fixedly installed on one inner wall of the flow limiting tube 8, which can cooperate with the valve needle 10 to control the flow rate of the filtrate.

[0027] In this embodiment, the flow limiting mechanism includes a valve needle 10, a threaded post 11, a hexagonal post 13, and a drive assembly. The threaded post 11 is slidably installed on the inner side of the flow limiting housing 12. A threaded groove is opened on the inner side of the flow limiting housing 12. The threaded post 11 is threadedly connected to the threaded groove. The valve needle 10 is fixedly installed at one end of the threaded post 11.

[0030] Working principle: During the filtration and impurity removal of the recovered liquid, the operator introduces the recovered liquid into the inner filter tank 3 inside the centrifuge tank 2. Then, the equipment is started, and the centrifugal servo motor 7 drives the drive wheel 5 to rotate. The rotation of the drive wheel 5 drives the driven wheel 4 to rotate via the belt 6. The rotation of the driven wheel 4 drives the inner filter tank 3 to rotate, generating centrifugal force. This causes the filtrate to be thrown out through the filter holes on the outside of the inner filter tank 3, while impurities remain in the inner filter tank 3. The filtrate then flows out through the precipitation hole at the bottom of the centrifuge tank 2 and enters the flow-limiting pipe 8. At this time, the operator starts the flow-limiting servo motor 16, which drives the worm gear 15 to rotate. The rotation of the worm gear 15 drives the... The worm gear 14 rotates, which drives the hexagonal column 13 to rotate, which in turn drives the threaded column 11 to rotate. The threaded column 11 is threadedly connected to the threaded groove on the inner side of the flow-limiting housing 12. Therefore, the threaded column 11 moves to the left. The movement of the threaded column 11 drives the valve needle 10 to move. The valve needle 10 moves away from the valve seat 9, thereby causing the filtrate to flow downward. The flow rate of the filtrate is controlled by controlling the distance between the valve needle 10 and the valve seat 9. The filtrate flows and drips onto the adsorption support 17, and then falls onto the adsorption net 20. At the same time, the scraper servo motor 18 starts and drives the scraper 19 to rotate, so that the filtrate is spread evenly on the adsorption net 20, which can more evenly adsorb impurities in the filtrate.

[0031] The technological advancement of this invention compared to the prior art is that it allows the centrifuged filtrate to slowly drip onto the adsorption mesh 20, while the scraper mechanism ensures that the filtrate is evenly spread across the surface of the adsorption mesh 20, thereby achieving a better filtration effect, improving work efficiency, and increasing the quality and purity of the filtrate.
