Description

Technical Field

[0001] This utility model relates to the field of metal ion recovery technology, and in particular to a metal ion concentration and recovery device for wastewater. Background Technology

[0002] Wastewater refers to the total amount of water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-water-using substances such as initial rainwater runoff into drainage pipes and ditches. The metal ions in wastewater are the ions of metal elements that have dissolved in water. Simply put, they are the metal elements in the molecules that make up the substance. In order to reduce the pollution of the environment by metal ions when wastewater is directly discharged, metal ions need to be concentrated and recovered before wastewater is discharged.

[0003] Announcement No. (CN218465589U) discloses a wastewater metal ion concentration and recovery device. After the metal ions in the wastewater fully react with the alkali, the one-way valves of the wastewater discharge pipes on both sides are opened. At this time, the wastewater inside the mixing tank is discharged from the inside of the wastewater discharge pipe. The second filter plate inside the wastewater discharge pipe separates the metal ion precipitate from the wastewater and discharges the wastewater inside the discharge funnel. Finally, after the wastewater inside the discharge funnel is drained, the one-way valve of the metal ion collection pipe is opened. At this time, the metal ion precipitate inside the discharge funnel can be discharged from the inside of the metal ion collection pipe to the outside of the mixing tank. The second filter screen in the above device is small. When there is a lot of metal ion precipitate accumulated in the metal ion collection pipe, the second filter screen will be blocked. This will cause the separation of wastewater and metal ion precipitate to fail to proceed normally, which needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a device for concentrating and recovering metal ions in wastewater in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A wastewater metal ion concentration and recovery device includes a filtration mechanism for filtering metal ion precipitates in wastewater, and a concentration mechanism for concentrating metal ions in wastewater is installed on the filtration mechanism.

[0007] The filtration mechanism includes a support leg, a housing is installed on the upper surface of the support leg, a drain pipe is installed on the rear surface of the housing, a first motor is fixed on the housing, a turntable is connected to the output end of the first motor, a positioning post is provided on the turntable, a tray is installed on the upper surface of the positioning post, a retaining ring is fixed on the upper surface of the tray, and a fixing rod is installed on the tray. There are four fixing rods, and a filter screen is installed between each two adjacent fixing rods.

[0008] The concentration mechanism includes fixed seats installed on both sides of the shell. An electric push rod is fixed on the upper surface of the fixed seat. The telescopic end of the electric push rod is connected to a lifting plate. A cylinder is inserted through the lifting plate. A second motor is installed on the upper surface of the cylinder. A wastewater pipe is installed on one side of the second motor. A reagent tube is installed on the other side of the second motor. A rotating shaft is installed at the output end of the second motor. A stirring blade is connected to the outer diameter of the rotating shaft. A water outlet pipe is fixed on the cylinder. A water distribution pipe is connected to the outer diameter of the water outlet pipe.

[0009] Preferably, there are four groups of stirring blades, with four stirring blades in each group.

[0010] Preferably, a solenoid valve is installed on the water outlet pipe.

[0011] Preferably, the turntable is rotatably connected to the housing.

[0012] Preferably, the positioning column is slidably connected to the turntable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up a filtration and concentration mechanism, wastewater and alkali are added to the inside of the cylinder in a certain proportion. The second motor is started, which drives the rotating shaft and stirring blades to rotate. The stirring blades agitate the wastewater and alkali. During the agitation process, the metal ions in the wastewater react with the alkali to form metal ion precipitates. After the reaction is completed, the second motor is turned off, and the solenoid valve on the outlet pipe and the first motor are turned on. The wastewater carrying the metal ion precipitates enters the area between the baffle ring and the filter screen through the outlet pipe and the distribution pipe. The filter screen filters the metal ion precipitates in the wastewater, trapping them in the area between the baffle ring and the filter screen. The filtered wastewater is discharged through the drain pipe. The first motor drives the turntable and tray to rotate, thus ensuring that the metal ion precipitates are evenly distributed in the area between the baffle ring and the filter screen. This method ensures that the filter screen will not become clogged, and the separation of wastewater and metal ion precipitates can continue, effectively improving the performance of the device.

After the reaction between the metal ions and the alkali is completed, the water outlet pipe 21 is opened. The solenoid valve and the first motor 104 on the device 0 allow wastewater carrying metal ion precipitates to enter the area between the baffle ring 108 and the filter screen 110 through the outlet pipe 210 and the branch pipe 211. The filter screen 110 filters the metal ion precipitates in the wastewater, trapping them in the area between the baffle ring 108 and the filter screen 110.
