Description

Technical Field

[0001] The utility model relates to the technical field of sodium ion batteries, in particular to a filtering device for sodium ion battery positive and negative electrode material wastewater. Background Art

[0002] The production of sodium-ion battery materials generates a large amount of wastewater. Direct discharge of this wastewater would severely pollute the environment. Therefore, wastewater from the production of sodium-ion battery cathode and anode materials is typically filtered before discharge.

[0003] For reference, Chinese utility model patent CN219815516U discloses a wastewater treatment mechanism for sodium ion battery production, including a filter box, a filter mechanism is installed inside the filter box, and an anti-blocking mechanism is installed on the left side of the filter box; the filter mechanism includes a first filter screen and a second filter screen, and the left and right sides of the first filter screen and the second filter screen are fixedly installed with fixed plates, and two mounting grooves are opened on the left and right inner walls of the filter box, and a sliding rod is fixedly installed inside the mounting groove.

[0004] In this utility model, in order to effectively prevent the filter from being blocked, an anti-blocking mechanism is provided. The motor drives the driving wheel to rotate, so that the two transmission belts drive the driven wheel to rotate, and the rotating rod drives the cam to rotate. During the rotation, the cam pushes the fixed plate, so that the slider can slide on the slide rod to squeeze the spring and make it expand and contract, so that the first filter screen and the second filter screen can shake up and down, which can prevent the filter holes on the filter screen from being blocked when filtering sewage.

[0005] As can be seen, the utility model essentially uses a vibrating filter to prevent clogging, and its structure is relatively complex. Furthermore, even if the filter is vibrated by a motor, the filtered particles are still trapped inside the filter and cannot be discharged. Over long-term use, they will accumulate, making cleaning more difficult and seriously affecting the filtration effect. Utility Model Content

[0006] The utility model aims to provide a filtering device for sodium ion battery positive and negative electrode material wastewater, which has the characteristics of good anti-blocking effect, high filtering efficiency and simple structure.

[0007] The utility model can be realized by the following technical solutions:

[0008] The utility model discloses a filtering device for wastewater of positive and negative electrode materials of sodium ion batteries, comprising a filter tube body, a filter cavity provided on the filter tube body, a <-shaped filter screen and a >-shaped filter screen respectively provided on both sides of the filter cavity, a fixed bottom plate provided at the bottom of the <-shaped filter screen and the >-shaped filter screen, a drain pipe for discharging wastewater penetrates from the fixed bottom plate into the filter cavity, passes through the <-shaped filter screen and the >-shaped filter screen on both sides, and is discharged to both sides after being filtered.

[0009] Furthermore, the top of the <-shaped filter screen and the >-shaped filter screen is a fixed top plate, and the fixed top plate is provided with a magnetic separation plate. By providing the magnetic separation plate, magnetic metal impurities are adsorbed on the magnetic separation plate and are recycled.

[0010] Furthermore, a water outlet nozzle is provided at the outlet end of the drain pipe, through which wastewater is sprayed into the filter chamber. By providing the water outlet nozzle, wastewater is sprayed out and impacts the filter surface, thereby preventing the filtered impurities from being adsorbed on the filter surface and improving the filtration efficiency.

[0011] Furthermore, the <-shaped filter includes an upper fixed filter and a lower movable filter, and the movable filter rotates about the connection point between the movable filter and the fixed filter. The rotation of the movable filter facilitates the cleaning of filtered impurities deposited on the fixed bottom plate below the filter.

[0012] Furthermore, the >-shaped filter includes a fixed filter at the top and a movable filter at the bottom. The movable filter rotates around the connection point between the movable filter and the fixed filter, and the rotation facilitates the cleaning of impurities deposited on the filter.

[0013] Furthermore, both the <-shaped filter and the >-shaped filter are multi-layer composite filters, each comprising a first filter, a second filter, and a third filter stacked outward from the interior of the filter chamber, with the apertures of the first, second, and third filters decreasing in gradient. This multi-layer filter structure improves filtration capacity and ensures filtration efficiency.

[0014] Furthermore, the fixed top plate is fixedly connected to the top of the filter chamber via a rotating shaft.

[0015] Furthermore, the side wall of the filter chamber is also provided with aeration holes, which are connected to compressed air or an aerator to aerate the wastewater.

[0016] Furthermore, the first filter screen, the second filter screen and the third filter screen are respectively arranged inside the frame in a drawer-like manner using a first fixing frame, a second fixing frame and a third fixing frame.

[0017] Furthermore, the filter tube body is a metal tube body or a plastic tube body.

[0018] The utility model provides a filtering device for sodium ion battery positive and negative electrode material wastewater, which has the following beneficial effects:

[0019] First, the anti-clogging effect is good. By setting the <-shaped filter and the >-shaped filter, a hexagonal space is formed inside the entire filter chamber. The filtered particles slide along the <-shaped and >-shaped shapes to the fixed bottom plate under the action of gravity and the impact of wastewater, and will not adhere to the <-shaped filter and the >-shaped filter, thus avoiding clogging of the filter;

[0020] Second, the filtration efficiency is high. The wastewater enters the filter chamber through the fixed bottom plate through the drainage pipe. After being blasted out, it has the gravity and injection force of the wastewater, forming a filtering water flow force, accelerating the filtration of wastewater to both sides;

[0021] Third, the structure is simple. In this utility model, by setting up a hexagonal filter cavity, the gravity of the water flow and the gravity of the filtered particles are realized to achieve efficient anti-clogging filtration. There is no need to use a motor or other transmission mechanism to prevent vibration and blockage, which effectively simplifies the structure and extends the service life.
