Description

Technical Field

[0001] The utility model relates to the technical field of lithium strip rolling oil, in particular to a lithium strip rolling oil filtering device. Background Art

[0002] With the rapid development of new energy technologies, people's demand for the energy density of high-energy-density energy storage devices is increasing. Lithium metal as a negative electrode material and pre-lithiation material can greatly improve the energy density of existing lithium-ion batteries. However, lithium metal has low strength and high viscosity, and is extremely difficult to process. In the lithium strip rolling process, the use of appropriate rolling oil is a key factor in ensuring the stability of the production process and improving product quality.

[0003] After the rolling oil has been used for a period of time, it needs to be filtered by a filtering device before it can continue to be used. The rolling oil filtering device can extend the service life of the rolling oil, but it still has certain problems: 1) The traditional rolling oil filtering device has a large loss of filtering materials and a high filtering cost; 2) The traditional rolling oil filtering device adopts active filtration, and the oil fluctuates greatly during the filtration process, and there are problems with uneven filtering effect and quality; 3) The traditional filtering device has high energy consumption; Therefore, in view of the above situation, it is urgent to develop a lithium strip rolling oil filtering device to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The utility model aims to provide a lithium strip rolling oil filtering device to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a lithium strip rolling oil filtering device, comprising a base, an oil storage tank, a sedimentation tank and a permeation tank, the oil storage tank and the sedimentation tank are both vertically installed on the top of the base, the permeation tank is vertically arranged on the top of the sedimentation tank, and is connected and fixed to the sedimentation tank;

[0006] The sedimentation tank also includes a liquid inlet ring pipe, a sedimentation baffle, a filter cartridge, a sewage valve and a sewage tank. The liquid inlet ring pipe is arranged around the bottom end of the sedimentation tank. A number of equally spaced branch pipes are arranged between the liquid inlet ring pipe and the sedimentation tank. The liquid inlet ring pipe is connected and fixed to the inside of the sedimentation tank through the branch pipes. The sedimentation baffle and the filter cartridge are sequentially embedded in the inside of the sedimentation tank and are detachably connected to the sedimentation tank. The sewage valve is vertically installed at the bottom end of the sedimentation tank. The sewage tank and the sewage valve are connected and fixed through a hose. The sedimentation filtering method can reduce the use of filtering materials and reduce filtering costs. At the same time, it can also reduce the difficulty of maintenance.

[0007] The permeation tank also includes a hemispherical filter cotton, an oil drain pipe and a detection elbow. The hemispherical filter cotton is embedded and installed in the middle position of the inside of the permeation tank. One end of the oil drain pipe is vertically penetrated through the middle position of the hemispherical filter cotton, and the other end of the oil drain pipe is horizontally penetrated through the side wall of the permeation tank. The detection elbow is vertically arranged on one side of the permeation tank and is connected with the inside of the permeation tank. By using hemispherical filter cotton with an overflow oil drain pipe, the rolling oil can pass through the filter material in a stable state to achieve the best filtering effect.

[0008] Preferably, a drain valve is installed at the bottom end of the oil storage tank, and a conduit is connected to the end of the drain valve. The end of the conduit is connected to and fixed to the liquid inlet of the liquid inlet ring pipe. The bottom end height of the oil storage tank is consistent with the height of the hemispherical filter cotton, allowing the rolling oil to be filtered inside it to smoothly enter the sedimentation tank and the permeation tank.

[0009] Preferably, a plurality of vertically arranged spoilers are installed at the bottom of the sedimentation baffle, a first vertical through groove is opened in the middle of the sedimentation baffle, and a 10 mm interval is maintained between the bottom ends of the plurality of spoilers and the inner wall of the sedimentation tank. The sedimentation baffle and the spoiler are arranged in combination to slow down the flow rate of the injected rolling oil, thereby promoting the sedimentation rate of large particle impurities contained therein.

[0010] Preferably, a plurality of filter brushes are embedded and installed inside the filter cartridge, and a plurality of second through grooves are opened at the top of the filter cartridge, so that the filter brushes can absorb fine particles contained in the rolling oil after preliminary precipitation (the filter brushes are made of nylon).

[0011] Preferably, a removable sealing gasket is installed between the connection part of the oil drain pipe and the hemispherical filter cotton, and a removable oil collecting hopper is installed at the top of the oil drain pipe. The removable sealing gasket can prevent unfiltered rolling oil from overflowing through the connection between the oil drain pipe and the hemispherical filter cotton. The top of the oil collecting hopper is only 20 mm away from the lowest position of the inner bottom of the hemispherical filter cotton. The rolling oil filtered by the hemispherical filter cotton and entering its interior can quickly flow into the oil collecting hopper and be discharged through the oil drain pipe.

[0012] Preferably, a liquid level alarm is nested and installed at the top of the detection elbow, and an exhaust pipe is arranged through the top of the detection elbow. The height of the liquid level alarm is 10 mm lower than the topmost height of the hemispherical filter cotton. When the hemispherical filter cotton is blocked, the unfiltered rolling oil will enter the detection elbow connected to it from the permeation tank, and finally trigger the liquid level alarm to prevent the oil storage tank from continuing to supply oil.

[0013] Compared with the prior art, the utility model provides a lithium strip rolling oil filtering device, which has the following beneficial effects:

[0014] 1. The rolling oil to be filtered is subjected to sedimentation treatment by using a sedimentation tank in combination with a sedimentation baffle.

The large particles of impurities are filtered by sedimentation, which can reduce the use of filtering consumables, reduce filtering costs, and reduce maintenance difficulty;

[0015] 2. The entire filtration process adopts a bottom-up overflow method, which makes the oil fluctuation smaller during the filtration process, is conducive to the sedimentation and adsorption of impurities, and ensures the filtration effect and quality;

[0016] 3. The entire filtration process is carried out by the self-flow of oil in the oil storage tank, which reduces the filtration energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example:

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a lithium strip rolling oil filtering device, comprising a base 10, an oil storage tank 20, a sedimentation tank 30 and a permeation tank 40, the oil storage tank 20 and the sedimentation tank 30 are both vertically installed on the top of the base 10, the permeation tank 40 is vertically arranged on the top of the sedimentation tank 30, and is connected and fixed to the sedimentation tank 30;

The drain valve 340 is vertically installed at the bottom end of the settling tank 30. The drain tank 350 is connected and fixed to the drain valve 340 through a hose. The use of a sedimentation-type filtration method can reduce the use of filtration materials and reduce filtration costs, and it can also reduce the difficulty of maintenance.

[0029] The permeation tank 40 also includes a hemispherical filter cotton 410, an oil drain pipe 420 and a detection elbow 430. The hemispherical filter cotton 410 is embedded and installed in the middle position of the inside of the permeation tank 40. One end of the oil drain pipe 420 is vertically penetrated through the middle position of the hemispherical filter cotton 410, and the other end of the oil drain pipe 420 is horizontally penetrated through the side wall of the permeation tank 40. The detection elbow 430 is vertically arranged on one side of the permeation tank 40 and is connected with the inside of the permeation tank 40. By using the hemispherical filter cotton 410 with the overflow oil drain pipe 420, the rolling oil can pass through the filter material in a stable state to achieve the best filtering effect.

[0030] Preferably, a drain valve 210 is installed at the bottom end of the oil storage tank 20, and the end of the drain valve 210 is connected to a conduit 220. The end of the conduit 220 is connected to and fixed to the liquid inlet of the liquid inlet ring pipe 310. The bottom end height of the oil storage tank 20 is consistent with the height of the hemispherical filter cotton 410, allowing the rolling oil to be filtered inside it to smoothly enter the sedimentation tank 30 and the permeation tank 40.

[0031] Preferably, a plurality of vertically arranged spoilers 321 are installed at the bottom of the sedimentation baffle 320, a vertically penetrating first through groove 322 is opened in the middle position of the sedimentation baffle 320, and a 10 mm interval is maintained between the bottom ends of the plurality of spoilers 321 and the inner wall of the sedimentation tank 30. The sedimentation baffle 320 and the spoiler 321 are arranged in coordination with each other to slow down the flow rate of the injected rolling oil, thereby promoting the sedimentation rate of large particle impurities contained therein.

[0032] Preferably, a plurality of filter brushes 331 are embedded and installed inside the filter cartridge 330, and a plurality of second through grooves 332 are opened at the top of the filter cartridge 330. The filter brushes 331 can absorb fine particles contained in the rolling oil after preliminary precipitation (the filter brushes are made of nylon).

The top of the oil collecting hopper 421 is only 20 mm away from the lowest position of the inner bottom of the hemispherical filter cotton 410. The rolling oil filtered by the hemispherical filter cotton 410 and entering its interior can quickly flow into the oil collecting hopper 421 and be discharged through the oil drain pipe 420.

[0034] Preferably, a liquid level alarm 431 is nested and installed at the top of the detection bend 430, and an exhaust pipe 432 is penetrated through the top of the detection bend 430. The height of the liquid level alarm 431 is 10 mm lower than the topmost height of the hemispherical filter cotton 410.

[0035] Working principle: open the drain valve 210 to a certain extent, and the rolling oil to be filtered in the oil storage tank 20 is guided to the liquid inlet ring pipe 310 through the drain valve 210 and the conduit 220, and then slowly introduced into the interior of the settling tank 30 through multiple branch pipes 311. When the rolling oil flows in the settling tank 30, it is blocked by the settling baffle 320 and the spoiler 321, and the flow rate is slowed down to the minimum. The large particle impurities contained in it slowly settle to the inner bottom of the settling tank 30, and then the rolling oil flows upward through the first through groove 322. When it passes through the filter cartridge 330, it is blocked by the filter cartridge 330. The flow rate slows down again, and fine particles of impurities adhere to the filter brush 331. The rolling oil after secondary filtration enters the permeation tank 40 through the second through groove 332. The rolling oil passes through the hemispherical filter cotton 410 and enters its interior, and is discharged through the oil collecting hopper 420 and the oil drain pipe 420. The staff regularly opens the drain valve 340 to discharge the impurities settled at the bottom of the sedimentation tank 30 into the drain tank 350. When the hemispherical filter cotton 410 is blocked, the rolling oil will trigger the liquid level alarm 431 through the connected detection bend 430.
