Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a multi-layer filter assembly for purifying tungsten liquid. Background Technology

[0002] In the field of tungsten liquid purification, traditional tungsten liquid filtration methods often suffer from poor filtration effect and low filtration efficiency. Most existing filtration devices employ a single filtration structure, meaning the tungsten liquid passes through only one layer of filter media. This method struggles to effectively remove various impurities from the tungsten liquid, especially for particles of different sizes, where limited filtration precision leads to unstable quality of the purified tungsten liquid. Furthermore, traditional filtration devices are mostly static, with the tungsten liquid relying primarily on gravity to pass through the filter media. This single power source results in slow filtration speeds, failing to meet the demands of large-scale, high-efficiency tungsten liquid purification production. Therefore, developing a tungsten liquid purification filtration device that can effectively improve filtration efficiency, enhance filtration effect, and reduce maintenance costs is of significant practical importance. Utility Model Content

[0005] A purification tank, wherein a liquid outlet pipe is provided at the bottom of the purification tank and a liquid inlet pipe is provided at the top of the purification tank;

[0006] The first filter barrel is rotatably disposed inside the purification barrel. The first filter barrel has a plurality of filter holes evenly distributed on it. The tungsten liquid to be purified input by the liquid inlet pipe flows into the first filter barrel.

[0007] The second filter barrel is rotatably disposed inside the purification barrel and is sleeved outside the first filter barrel. The second filter barrel has a plurality of filter holes evenly distributed on it.

[0008] The third filter barrel is rotatably disposed inside the purification barrel and is sleeved outside the second filter barrel. The third filter barrel has a plurality of filter holes evenly distributed on it. The first filter barrel, the second filter barrel, and the third filter barrel are coaxially arranged, and the diameter of the filter holes on the first filter barrel, the second filter barrel, and the third filter barrel gradually decreases.

[0009] A rotational power unit is provided, which is mounted on the purification tank, and the rotating shaft of the rotational power unit is connected to the first filter tank, the second filter tank, and the third filter tank.

[0010] In one embodiment, a backwashing system is further included, the backwashing system comprising a backwashing water inlet pipe and a backwashing water outlet pipe, the backwashing water inlet pipe being disposed at the bottom of the purification tank and the backwashing water outlet pipe being disposed at the top of the purification tank, the backwashing water inlet pipe being connected to a backwashing pump; a first valve, a second valve, a third valve, and a fourth valve are sequentially disposed on the outlet pipe, inlet pipe, backwashing water inlet pipe, and backwashing water outlet pipe.

[0011] In one embodiment, the first filter barrel and the second filter barrel have through holes at the center of their bottoms, and the rotating shaft passes through the through holes to connect with the third filter barrel.

The tungsten liquid to be purified passes sequentially through these three filter barrels, enabling graded filtration of impurities of different sizes, significantly improving the purification effect and ensuring stable quality of the purified tungsten liquid. Furthermore, the rotation of the first, second, and third filter barrels by a power unit utilizes centrifugal force to generate stronger fluidity and impact force in the tungsten liquid during filtration, effectively reducing impurity accumulation on the filter media surface and preventing filter cake formation. Simultaneously, centrifugal force accelerates the speed at which the tungsten liquid passes through the filter pores, thereby significantly improving filtration efficiency and meeting the needs of large-scale, high-efficiency tungsten liquid purification production.

[0025] Please see Figures 1 to 2 This application provides a multi-layer filtration assembly for tungsten liquid purification, including a purification tank 1, a first filter tank 2, a second filter tank 3, a third filter tank 4, and a rotating power unit 5. The purification tank 1 has an outlet pipe 11 at its bottom and an inlet pipe 12 at its top. The first filter tank 2 is rotatably disposed within the purification tank 1, and has a plurality of evenly distributed filter holes. The tungsten liquid to be purified, input through the inlet pipe 12, flows into the first filter tank 2. The second filter tank 3 is rotatably disposed within the purification tank 1 and is fitted over the first filter tank 2, and has a plurality of evenly distributed filter holes. The third filter tank 4 is rotatably disposed within the purification tank 1 and is fitted over the second filter tank 3, and has a plurality of evenly distributed filter holes. The first filter tank 2, the second filter tank 3, and the third filter tank 4 are coaxially arranged, and the pore size of the filter holes on the first filter tank 2, the second filter tank 3, and the third filter tank 4 gradually decreases. The rotating power unit 5 is installed on the purification tank 1, and the rotating shaft 51 of the rotating power unit 5 is connected to the first filter tank 2, the second filter tank 3, and the third filter tank 4.

[0026] The multi-layer filtration assembly for tungsten liquid purification provided by this utility model involves the tungsten liquid to be purified entering the first filter tank 2 through an inlet pipe 12 located at the top of the purification tank 1. After being filtered by the first filter tank 2, it enters the outer second filter tank 3, and then the outer third filter tank 4. Finally, after being filtered by the third filter tank 4, the purified liquid is discharged from the outlet pipe 11 at the bottom of the purification tank 1. This achieves graded filtration of impurities of different particle sizes, greatly improving the purification effect of the tungsten liquid and ensuring the stability of the quality of the purified tungsten liquid. Furthermore, the rotation of the first filter tank 2, second filter tank 3, and third filter tank 4 is driven by a rotating power unit 5 (specifically, a motor), which utilizes the centrifugal force of rotation to significantly improve the filtration efficiency.

[0027] In one embodiment, a backwashing system 6 is also included. The backwashing system 6 includes a backwashing water inlet pipe 61 and a backwashing water outlet pipe 62. The backwashing water inlet pipe 61 is located at the bottom of the purification tank 1, and the backwashing water outlet pipe 62 is located at the top of the purification tank 1. The backwashing water inlet pipe 61 is connected to the backwashing pump. A first valve 7, a second valve 8, a third valve 9, and a fourth valve 10 are sequentially provided on the outlet pipe 11, the inlet pipe 12, the backwashing water inlet pipe 61, and the backwashing water outlet pipe 62.

[0028] The backwashing system 6 inputs backwash water to the bottom of the purification tank 1 through the backwash water inlet pipe 61. Under pressure, the backwash water flows upward from the bottom of the purification tank 1, passes through the filter holes of the filter tank, and washes away impurities attached to the filter holes and the surface of the filter tank. Then, it is discharged from the backwash water outlet pipe 62 at the top of the purification tank 1. By controlling the opening and closing of the first valve 7, the second valve 8, the third valve 9, and the fourth valve 10, the normal filtration mode and the backwashing mode can be flexibly switched to achieve regular cleaning of the filter components.

[0029] During backwashing, close the first valve 7 and the second valve 8, and open the third valve 9 and the fourth valve 10. The backwash pump then pumps backwash water into the bottom of the purification tank 1, flushing out impurities attached to each filter tank. These impurities are then discharged from the backwash water outlet pipe 62 at the top along with the backwash water. This effectively removes accumulated impurities from the filter tanks, restores filtration performance, and extends the service life of the filter components.

[0030] In one embodiment, the bottom center of the first filter barrel 2 and the second filter barrel 3 are provided with through holes, and the rotating shaft 51 passes through the through holes and is connected to the third filter barrel 4. The first filter barrel 2 and the second filter barrel 3 are connected to the rotating shaft 51 by seamless welding.

[0031] In one embodiment, a freely rotatable steel ball 13 is provided in the rotatable connection area between the first filter barrel 2, the second filter barrel 3, the third filter barrel 4 and the purification barrel 1. The steel ball 13 can generate rolling friction between the filter barrels and the purification barrel 1. Compared with sliding friction, rolling friction has less resistance, thus making the filter barrels rotate more smoothly. This not only reduces the load on the rotating power unit 5 and reduces energy consumption, but also reduces wear caused by friction, extending the service life of the rotating power unit 5 and the filter assembly.

[0032] In one embodiment, activated carbon is filled between the sidewalls of the second filter barrel 3 and the third filter barrel 4. Activated carbon has a rich microporous structure and a large specific surface area, enabling it to adsorb minute impurities, organic matter, and other harmful substances from the tungsten liquid through physical and chemical adsorption. When the tungsten liquid passes through the area between the second filter barrel 3 and the third filter barrel 4, the activated carbon adsorbs the impurities, thereby further improving the purification quality of the tungsten liquid.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
