The liquid material purification and separation device drives the centrifuge tube to rotate by an electric motor to achieve separation of liquid material and water vapor. The separated liquid material has a higher temperature. The liquid material flows to the surface of the filter plate below, which can heat the upper part of the housing to prevent the liquefaction of water vapor. The filter holes on the two layers of filter plates are not on the same plane, which slows down the downward flow of the liquid material.

[0004] In the prior art, liquid materials and water vapor can be separated by setting up a centrifuge tube, and the two materials can be collected and filtered separately. However, the overall use still has the following problems: First, when separating and purifying liquid nitrogen, the prior art causes liquid nitrogen to vaporize during separation due to its extremely low boiling point, resulting in a waste of resources; second, the filter screen of the prior art is difficult to replace, and a large amount of structure needs to be disassembled, which is time-consuming and labor-intensive. Excessive disassembly also affects use, and long-term non-replacement will also lead to reduced filtering effect. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Example 1:

[0026] refer to Figure 1 、 Figure 2 and Figure 3 A liquid separation and purification device includes a main body 1, an inner liner 2 is provided inside the main body 1, a vacuum chamber 3 is provided between the main body 1 and the inner liner 2, a detachable bottom cover 4 is provided at the bottom of the inner liner 2, a bracket 5 is coaxially provided on the upper end of the bottom cover 4, a plurality of filter blocks 6 are provided on the outer circular surface of the bracket 5 in the circumferential direction, a push rod 7 is provided on the end surface of the bottom cover 4 in the multiple brackets 5, a movable block 8 is provided above the push rod 7, a support block 9 with an inclined surface is provided on the inner wall of the inner liner 2, a leakage groove 10 is provided in the center of the support block 9, an annular magnetic plate 11 is provided inside the support block 9, a vacuum pump 12 is provided outside the main body 1, and the output end of the vacuum pump 12 is connected to the vacuum chamber 3.

[0027] In this solution, the bracket 5 is annular as a whole, and a plurality of notches are provided on the outer surface of the bracket 5. A plurality of filter blocks 6 are respectively installed inside the plurality of notches. The bracket 5 can support the filter block 6 and improve the pressure-bearing capacity of the filter block 6; the end face thickness of the support block 9 close to the axis is smaller, and the outer circumferential surface thickness is larger, forming a shape with a low middle and a high circumference. This setting has a good guiding effect, can increase the flow rate of liquid nitrogen, and thus improve the filtration efficiency. The bottom of the movable block 8 is a metal material that can be adsorbed by the magnetic plate 11. This setting can form a sealing effect when the push rod 7 is removed, so that the device can better store liquid nitrogen; an annular bracket 24 is provided on the outside of the main body 1, and the vacuum pump 12 is fixedly connected to the end face of the annular bracket 24. The vacuum pump 12 is a prior art and will not be elaborated in this article. Its main function is to extract the air in the vacuum chamber 3 so that the vacuum chamber 3 is in a vacuum state. The vacuum chamber 3 in the vacuum state can isolate the heat transfer between the inner tank 2 and the external environment, thereby reducing the volatilization of the liquid.

[0028] refer to Figure 1 and Figure 2 A liquid outlet pipe 13 is provided inside the main body 1, one end of the liquid outlet pipe 13 passes through the vacuum chamber 3 and is connected to the inner tank 2, a liquid inlet 14 is provided on the top of the main body 1, the liquid inlet 14 is connected to the inner tank 2, and a pressure relief pipe 22 for releasing gas is provided on the top of the main body 1.

[0029] In this solution, a small amount of liquid nitrogen will volatilize in the inner liner 2, and the nitrogen can be discharged through the pressure relief pipe 22, which can effectively prevent the inner liner 2 from bursting due to internal gas pressure, thereby increasing the service life of the device.

[0030] refer to Figure 1 、 Figure 2 and Figure 3 A fixed block 15 protruding outward is provided at the bottom of the inner liner 2, and a sunken groove 16 is provided on the end surface of the bottom cover 4. The fixed block 15 is threadedly connected to the groove 16. A fixing frame 23 is provided on the inner wall of the inner liner 2, and a telescopic rod 25 is provided on the bottom end surface of the fixing frame 23. The other end of the telescopic rod 25 is fixedly connected to the movable block 8.

[0031] In this solution, the fixing frame 23 is cross-shaped as a whole and is fixedly connected to the inner wall of the inner liner 2 to support the interior of the inner liner 2. The fixing frame 23 can prevent the vacuum pump 12 from causing the inner liner 2 to deform when extracting air from the vacuum chamber 3, thereby improving the stability of the device. The telescopic rod 25 can limit the moving direction of the movable block 8, so that the movable block 8 can move up and down, preventing the movable block 8 from tilting when being lifted by the push rod 7, thereby ensuring the service life of the device.

[0032] refer to Figure 2 、 Figure 3 and Figure 5 A mounting groove 17 is provided on the bottom end surface of the bottom cover 4 , a handle 18 is provided inside the mounting groove 17 , and a first sealing ring 19 is provided on the top outer circular surface of the bottom cover 4 .

[0033] In this solution, the handle 18 is installed inside the mounting groove 17, which makes it easy to unscrew the mounting groove 17, and also allows the bottom of the bottom cover 4 to be placed stably, preventing the bottom cover 4 from tilting, ensuring uniform force, and improving the service life of the device. By setting a first sealing ring 19, when the bottom cover 4 is connected to the main body 1, the bottom cover 4 will abut the first sealing ring 19 against the bottom of the inner liner 2 during the process of tightening, thereby forming a seal. This setting can improve the sealing between the bottom cover 4 and the inner liner 2.

[0034] refer to Figure 2 and Figure 3 The upper end surface of the movable block 8 is in the shape of a protruding truncated cone as a whole, and a second sealing ring 20 is provided on the bottom end surface of the movable block 8.

[0035] In this solution, the upper end surface of the movable block 8 is set to be a truncated cone, which can prevent liquid nitrogen from remaining on the top of the movable block 8 and guide the liquid nitrogen to flow to both sides, thereby improving the filtration efficiency. When the movable block 8 contacts the magnetic plate 11, the magnetic plate 11 will adsorb the movable block 8, thereby squeezing the second sealing ring 20 at the bottom of the movable block 8, so that the second sealing ring 20 can effectively improve the sealing between the movable block 8 and the magnetic plate 11.

[0036] refer to Figure 3 and Figure 4 , a third sealing ring 21 is provided on the end surface of the bracket 5.

[0037] In this solution, when the bottom cover 4 is connected to the main body 1, the bottom cover 4 will abut the third sealing ring 21 against the bottom end face of the support block 9 during the process of tightening, thereby forming a seal, so that the third sealing ring 21 can improve the sealing between the bracket 5 and the support block 9, preventing the liquid nitrogen with impurities from leaking out during filtration, thereby ensuring the filtering effect.

[0038] When in use, first start the vacuum pump 12 so that the vacuum pump 12 extracts the air in the vacuum chamber 3, so that the vacuum chamber 3 maintains a vacuum state, and then rotate the bottom cover 4 so that the bottom cover 4 is threadedly connected to the fixed block 15 through the groove 16. During the rising process of the bottom cover 4, it will drive the top push rod 7 to rise, and the push rod 7 passes through the leakage groove 10 and continues to rise. The push rod 7 contacts the movable block 8 and lifts the movable block 8, so that the movable block 8 is separated from the end face of the support block 9. The movable block 8 will squeeze the telescopic rod 25 when lifting and rise along the direction of the telescopic rod 25. After the movable block 8 is lifted, the inner liner 2 is connected with the bottom filter block 6 through the leakage groove 10. At the same time, the third sealing ring 21 on the upper end face of the bracket 5 will be squeezed against the bottom of the inner liner 2 to form a sealing effect.

[0039] At this time, liquid nitrogen is injected from the liquid inlet 14, and the liquid nitrogen flows into the interior of the bracket 5 from the leakage groove 10 along the inclined surface of the support block 9. The impurities in the liquid are filtered by the filter block 6, and the liquid nitrogen is discharged from the liquid outlet pipe 13 through the filter block 6. During the filtration period, a small amount of liquid nitrogen will be vaporized, and nitrogen will enter the inner liner 2. At this time, the pressure relief pipe 22 is opened to discharge the nitrogen in the inner liner 2 to prevent the nitrogen from damaging the inner liner 2.
