Abstract

This application discloses an energy-saving device for liquid filling, relating to the field of liquid filling. It includes a transmission pipe, a three-way valve, a heat exchange box, a cooling tank, and a gas transmission pipe. Control components are installed inside both transmission pipes. A cooling component is installed between the cooling tank and the heat exchange box. Liquid argon can be introduced into the gas transmission pipe and then into the vaporization pipe. The heat exchange box allows heat exchange between air and the vaporization pipe, vaporizing the liquid argon and introducing it into a buffer tank.

The worm gear and worm wheel work together to drive the rotating shaft, which in turn drives the sealing ball to rotate. The limiting block and arc groove work together to limit the sealing ball's maximum rotation by 90 degrees, thereby rotating the through-hole inside the sealing ball to the same position as the transmission pipe's axis, thus opening the sealing ball for feeding.

Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, and in particular to an energy-saving device for liquid filling. Background Technology

[0002] Liquid argon is a chemical substance, the liquid form of argon gas. Argon is an inert gas, colorless, odorless, and tasteless at standard atmospheric pressure, widely distributed in the Earth's atmosphere, making up approximately 0.93% of its volume. Liquid argon is obtained by liquefying argon gas under low temperature and high pressure conditions. Its boiling point is -185.848℃, and it evaporates rapidly at room temperature and pressure. Industrially, due to its chemical inertness, argon gas is often used as a protective gas and can also be used as a coolant.

[0003] When filling liquid argon, a portion of liquid argon needs to be introduced beforehand to allow it to evaporate within the pipeline and tank, thereby absorbing heat from the pipeline and tank and achieving a pre-cooling effect. This gradual pre-cooling of the pipeline and tank prevents the extremely low temperature of the liquid argon from being directly introduced, which could cause excessive thermal stress in the pipeline or tank due to a large temperature difference, potentially leading to deformation or damage.

[0004] The existing method of pre-cooling liquid argon involves directly introducing a small amount of liquid argon into the pipeline during refilling, allowing the liquid argon to evaporate within the pipeline and absorb heat. This pre-cooling method achieves pre-cooling through a single evaporation and heat absorption, resulting in low pre-cooling efficiency and excessively long pre-cooling time. This prolonged pre-cooling leads to a significant waste of liquid argon evaporation, increasing filling costs. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an energy-saving device for liquid filling, including two transmission pipes 2, a three-way valve 1 installed between the two transmission pipes 2, and a control component 7 installed inside each of the two transmission pipes 2. A heat exchange box 5 is installed at the end of one of the transmission pipes 2 away from the three-way valve 1. A cooling tank 3 is installed on the side of the heat exchange box 5 away from the three-way valve 1. A cooling component 4 is installed between the cooling tank 3 and the heat exchange box 5. A gas supply pipe 6 is connected between the top of the three-way valve 1 and the heat exchange box 5.

[0029] Cooling assembly 4 includes a vaporization pipe 401 installed inside heat exchange box 5. Vaporization pipe 401 is connected to gas supply pipe 6. The end of vaporization pipe 401 away from three-way valve 1 is connected to buffer box 402. Two air guide rings 405 are installed inside cooling tank 3. Several spiral cooling pipes 404 are installed between the two air guide rings 405. Two guide blocks 407 are installed on the side of each air guide ring 405 away from the spiral cooling pipes 404. The guide block 407 above the side closest to three-way valve 1 connects to buffer box 402. An air inlet pipe 408 is connected between the two guide blocks 407 that are far from the three-way valve 1. An air vent pipe 406 is connected between the two guide blocks 407 that are far from the three-way valve 1. An air inlet pipe 408 is installed on both sides of the buffer box 402. One end of the air inlet pipe 408 passes through the outer surface of the cooling tank 3 and is connected to the adjacent guide block 407. The air inlet pipe 408 enables the buffer box 402 to supply air to the adjacent guide block 407. The air vent pipe 406 enables gas flow between the two guide blocks 407 that are far from the three-way valve 1.

[0030] Specifically, the transmission pipe 2, which is close to the cooling tank 3, passes through the cooling component 4 and the interior of the cooling tank 3. The vaporization pipe 401 is in the shape of a planar spiral. The outer surface of the heat exchange box 5 is provided with a vent hole for ventilation. Through the planar spiral vaporization pipe 401, the liquid argon passing through the vaporization pipe 401 can stay in the heat exchange box 5 for a sufficient time, so that the liquid argon can exchange heat with the air in the heat exchange box 5 and achieve vaporization, thereby increasing the temperature of the argon gas and assisting in pre-cooling. This avoids the large temperature change caused by directly introducing liquid argon, which would affect the service life of the transmission pipe 2.

[0031] Specifically, the guide block 407 has an internal air guide groove, and the air guide ring 405 has an internal through hole that mates with the spiral cooling pipe 404. The spiral cooling pipe 404 passes through the through hole and connects with the air guide groove inside the guide block 407. Through the design of the guide block 407 and the internal through hole of the air guide ring 405, the spiral cooling pipe 404 is divided into upper and lower parts by the difference between air intake and exhaust. The spiral cooling pipe 404 that intakes through the guide block 407 on the side closer to the buffer tank 402 and exits through the guide block 407 on the side farther from the buffer tank 402 can be considered as the upper part. The upper spiral cooling pipe 404 is equipped with a lower spiral cooling pipe 404. The lower spiral cooling pipe 404 receives air through a guide block 407 located below the buffer tank 402 and exits through the guide block 407 located near the buffer tank 402. The upper spiral cooling pipe 404 exits through the guide block 407 located above the buffer tank 402 and then enters the lower spiral cooling pipe 404 through the vent pipe 406. This allows the argon gas in the spiral cooling pipe 404 to be transported back and forth once, increasing the residence time of argon gas in the cooling tank 3, improving the cooling effect, and achieving pre-cooling without evaporating too much liquid argon.

[0032] Specifically, a vacuum gas storage cylinder 403 is connected to the outer surface of the guide block 407 below the buffer box 402 via a connecting pipe. The vacuum gas storage cylinder 403 can recover argon gas cooled by the spiral cooling pipe 404. Both sides of the buffer box 402 are provided with fixing rings for fixing the gas storage cylinder. After the gas exits from the lower spiral cooling pipe 404, it is introduced into the vacuum gas storage cylinder 403. The vacuum gas storage cylinder 403 is detachable and is clamped by the fixing rings. The gas storage cylinder can be disassembled later to realize the recovery of pre-cooled argon gas and avoid waste.

[0033] Furthermore, the inner diameter of the gas supply pipe 6 is smaller than that of the transmission pipe 2, thereby controlling the flow rate into the gas supply pipe 6 and the cooling component 4, avoiding excessive flow that would cause vaporization waste. Liquid argon can flow into the gas supply pipe 6, and then into the vaporization pipe 401. Air circulation is achieved through the vent holes on the outer surface of the heat exchange box 5, allowing heat exchange with the vaporization pipe 401. This enables the liquid argon passing through the vaporization pipe 401 to absorb heat and vaporize, then flow into the buffer box 402. The buffer box 402 stabilizes the gas pressure, ensuring that the gas, after passing through it, is evenly distributed. The gas is stably fed into the upper spiral cooling pipe 404. After the transmission pipe 2 passing through the cooling tank 3 is cooled by the upper spiral cooling pipe 404, it is then fed into the lower spiral cooling pipe 404 through the vent pipe 406. The gas then returns through the lower spiral cooling pipe 404, thus achieving cooling again, improving cooling efficiency and avoiding waste from liquid argon vaporization. The connection relationship, working principle and operation sequence between the three-way valve 1 and the vacuum storage cylinder 403 and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0034] Example 2

[0035] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The control component 7 includes a blocking ball 701 that is movably installed inside the transmission pipe 2. A rotating shaft 703 is installed on the top of the blocking ball 701. Two limiting blocks 702 are installed on the outer surface of the rotating shaft 703. A worm gear 704 is fixedly installed on the outer surface of the rotating shaft 703 below the limiting blocks 702. A worm 705 is provided on one side of the worm gear 704.

[0036] Specifically, a fixed cover 706 is installed on the outer surface of both transmission pipes 2. The worm 705 is movably installed inside the fixed cover 706 and is meshed with the worm wheel 704. One end of the worm 705 passes through the outer surface of the fixed cover 706 and is fitted with a nut. The sealing ball 701 has a through hole for feeding. Two control components 7 are respectively set on both sides of the three-way valve 1. The fixed cover 706 provides protection for the worm wheel 704 and the worm 705 inside. In addition, a flow sensor and a temperature sensor are installed inside the transmission pipe 2 to help monitor the flow and temperature inside the transmission pipe 2.

[0037] Specifically, the top of the inner cavity of the fixing cover 706 is provided with a slot 707 that mates with the rotating shaft 703. Arc-shaped grooves 708 that mate with the limiting block 702 are provided on both sides of the slot 707. The rounded corners of the arc-shaped grooves 708 are 90 degrees. Through the slot 707 and the arc-shaped grooves 708, the maximum rotation of the rotating shaft 703 is limited to 90 degrees, thus preventing the sealing ball 701 from over-rotating and causing accidental opening. The sealing ball 701 is made of low-temperature resistant material, and its outer surface remains sealed to the inner wall of the transmission pipe 2 and between the rotating shaft 703 and the transmission pipe 2, thereby ensuring the sealing ball 701 withstands pressure. The outer surface of the transmission pipe 2 is provided with a through hole that mates with the rotating shaft 703. The bottom of the rotating shaft 703 passes through the through hole and connects to the top of the sealing ball 701.

[0038] Furthermore, the worm gear 705 and worm wheel 704 work together to drive the rotating shaft 703 to rotate, which in turn drives the sealing ball 701 to rotate. Through the cooperation of the limiting block 702 and the arc groove 708, the sealing ball 701 is limited to rotate a maximum of 90 degrees, thereby driving the through hole inside the sealing ball 701 to rotate to the same position as the axis of the transmission pipe 2, thus opening the sealing ball 701 to feed material. With the help of the flow sensor and temperature sensor, the worker can adjust the flow rate of the internal transmission pipe 2 according to the real-time precooling effect to improve the precooling effect. The connection relationship, working principle and operation sequence of the flow sensor and temperature sensor and other components are existing technology and are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0039] Working principle: During the pre-cooling operation of liquid argon filling, open the control component 7 on the side of the three-way valve 1 away from the cooling tank 3. Turn the nut at one end of the worm gear 705 using an Allen wrench or other tools. This, through the cooperation of the worm gear 705 and the worm wheel 704, drives the rotating shaft 703 to rotate, which in turn drives the sealing ball 701 to rotate. Through the cooperation of the limiting block 702 and the arc groove 708, the sealing ball 701 is limited to rotate a maximum of 90 degrees, thereby driving the sealing ball 701 to rotate. The through-hole of the part is rotated to the same position as the axis of the transmission pipe 2, thereby opening the sealing ball 701 to allow feeding, while the control component 7 of the three-way valve 1 near the cooling tank 3 remains closed, allowing liquid argon to enter the gas transmission pipe 6, and then into the vaporization pipe 401. Air circulation is achieved through the vent holes on the outer surface of the heat exchange box 5, enabling heat exchange with the vaporization pipe 401. This allows the liquid argon passing through the vaporization pipe 401 to absorb heat and vaporize, thus entering the buffer tank 402. Inside, the gas pressure is stabilized by the buffer box 402, allowing the gas to be smoothly introduced into the upper spiral cooling pipe 404 after being buffered by the buffer box 402. After the upper spiral cooling pipe 404 cools the transmission pipe 2 passing through the cooling tank 3, it is introduced into the lower spiral cooling pipe 404 through the vent pipe 406, and then returned through the lower spiral cooling pipe 404 for further cooling, improving cooling efficiency and avoiding waste from liquid argon vaporization. The returned argon gas is introduced into the vacuum storage cylinder 403 for later recovery. After the initial pre-cooling is completed, the control component 7 of the three-way valve 1 near the cooling tank 3 is slightly opened, allowing a small amount of liquid argon to enter the transmission pipe 2, thus achieving synchronous pre-cooling inside and outside. After the pre-cooling is completed, both control components 7 can be fully opened, and the gas path to the top gas supply pipe 6 is closed by the three-way valve 1, allowing liquid argon to be filled through the transmission pipe 2, thus completing the pre-cooling operation for liquid argon filling.
