Description

Technical Field

[0001] This utility model relates to the technical field of liquid degassing equipment, and in particular to an instantaneous heating vacuum degassing device. Background Technology

[0002] In industrial production processes, dissolved gases in liquids can adversely affect product quality or experimental results. In electronic chip manufacturing, the liquids used for encapsulation contain gases, which can easily generate bubbles during the curing process, affecting chip performance. In order to efficiently remove dissolved gases from liquids, a vacuum degassing device is needed.

[0003] Existing vacuum degassing devices consist of a vacuum tank, a vacuum pump, and a simple gas collection device. In use, the liquid to be degassed is first injected into the vacuum tank, and then the vacuum pump is activated to extract air from the tank, creating a vacuum environment. The principle of reduced gas solubility under vacuum causes gas to escape from the liquid, and the escaped gas is processed by the collection device. However, this type of degassing device exhibits significant problems in practical applications. Firstly, the liquid mixing is uneven. Due to the lack of a reasonable stirring or flow guiding structure inside the device, the liquid remains essentially static within the tank, resulting in significant differences in the degree of gas escape in different areas. Liquids near the tank walls and bottom have varying degrees of contact with the vacuum environment and gas escape channels, making it difficult for gas to escape fully. This leads to inconsistent overall degassing results, failing to meet the requirements of production processes with extremely high degassing precision. Secondly, existing degassing devices cannot be heated. Their design relies solely on the vacuum environment to promote gas escape, without considering that heating can accelerate the movement of gas molecules, thereby more efficiently separating the gas from the liquid, resulting in low degassing efficiency. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an instantaneous vacuum degassing device, comprising a vacuum tank 1, which serves as the main bearing space for the entire degassing process and provides a location for liquid degassing. A vacuum pump 4 is fixedly connected to the top of the vacuum tank 1 to extract air from the vacuum tank 1 and create a vacuum environment. The left end of the vacuum pump 4 is connected to an air extraction pipe 5, and the bottom end of the air extraction pipe 5 is connected to the vacuum tank 1. A motor 6 is fixedly connected to the middle of the top of the vacuum tank 1, providing power for stirring. The output end of the motor 6 passes through the vacuum tank 1 and is fixedly connected to a stirring rod 7. Multiple stirring rods are fixedly connected to the upper and lower sides of the outer wall of the stirring rod 7. Each stirring blade 8, rotating with the stirring rod 7, stirs the liquid inside the vacuum tank 1, making the liquid mix more evenly. Multiple turbulence holes 9 are formed on the surface of each stirring blade 8 to further disrupt the liquid flow, enhance the stirring effect, and ensure that all parts of the liquid fully contact the vacuum environment and heat. A heating plate 10 is fixedly connected to the outer wall of the vacuum tank 1 to enclose it and provide a mounting position for the internal heating wire 11. The heating plate 10 contains the heating wire 11, which generates heat during operation and transfers it to the liquid inside the vacuum tank 1, accelerating the movement of gas molecules in the liquid. The dynamic speed facilitates the separation of gas from liquid. A feed pipe 12 is connected to the front of the outer wall of the vacuum tank 1, serving as a channel for liquid to enter the vacuum tank 1 and guiding the liquid to be degassed into the flow. A discharge pipe 13 is connected to the bottom of the vacuum tank 1 to discharge the degassed liquid. Control valves 14 are fixedly connected to the outer walls of both the feed pipe 12 and the discharge pipe 13, respectively controlling the inflow and outflow of liquid in the feed pipe 12 and the discharge pipe 13, ensuring the orderly progress of the degasing process. A degasing assembly is installed on the outer wall of the control valve 14. A filter mechanism 2 is installed on the front of the outer wall of the vacuum tank 1, used for pre-filtering the liquid. The degassing assembly includes a connecting pipe 15, the front end of which is connected to the middle of the rear side of the outer wall of the discharge pipe 13. The connecting pipe 15 is used to connect the discharge pipe 13 and the diaphragm pump 16, so that the liquid after preliminary degassing can enter the diaphragm pump 16. The rear end of the connecting pipe 15 is connected to the diaphragm pump 16, which provides power for further liquid transportation and transports the preliminarily degassed liquid to the membrane stripper 17. The top of the diaphragm pump 16 is connected to the membrane stripper 17, which performs deep degassing treatment on the liquid, allowing the residual gas in the liquid to pass through a special membrane structure. The top of the membrane stripper 17 is connected to a pipe 18, and the left end of the pipe 18 is connected to the vacuum tank 1.

[0032] Specifically, the vacuum tank 1 provides space for degassing. The vacuum pump 4 at the top is connected to the vacuum tank 1 via a suction pipe 5, drawing air from inside the tank to create a vacuum environment, reducing gas solubility and causing gas to escape. The motor 6 at the top center of the vacuum tank 1 has its output end connected to a stirring rod 7 through the tank 1. Multiple stirring blades 8 are fixed to the upper and lower sides of the outer wall of the stirring rod 7, and their surfaces have turbulence holes 9. The motor 6 drives the stirring rod 7 and stirring blades 8 to rotate, promoting liquid circulation. The turbulence holes 9 disrupt the flow, ensuring uniform liquid mixing, and allowing all parts to be fully heated and in contact with the vacuum, improving the uniformity and efficiency of degassing. The heating plate 10 on the outer wall of the empty tank 1 has a heating wire 11 inside. The heating plate accelerates the movement of gas molecules and works in conjunction with the vacuum environment to improve the degassing effect. The feed pipe 12 on the front side of the outer wall of the vacuum tank 1 and the discharge pipe 13 at the bottom control the liquid inflow and outflow respectively. The control valve 14 on the outer wall adjusts the flow rate and discharge timing. In the degassing assembly, the front end of the connecting pipe 15 is connected to the discharge pipe 13, and the rear end is connected to the diaphragm pump 16. The diaphragm pump 16 sends the initially degassed liquid to the top membrane stripper 17. The membrane stripper 17 allows the residual gas to pass through the membrane structure and return to the vacuum tank 1 through the pipe 18, where it is pumped away by the vacuum pump 4 to achieve deep degassing.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The filtration mechanism 2 includes a filter box 201, which serves as the main container for filtration and provides space for the entire filtration process. The rear end of the filter box 201 is connected to the front end of the discharge pipe 13. Fixed seats 202 are fixedly connected to the four corners of the inner wall of the filter box 201. A filter frame 203 is slidably connected to the inner wall of the filter box 201, allowing for easy installation, disassembly, and replacement. Positioning pins 204 are fixedly connected to the four corners of the bottom of the filter frame 203. Positioning grooves 205 are provided on the tops of the multiple fixed seats 202, and the multiple positioning pins 204 are respectively positioned with... The corresponding positioning groove 205 engages to achieve precise positioning of the filter frame 203 within the filter box 201. A sealing ring 206 is fixedly connected to the top of the filter box 201, which seals the filter box 201 when the sealing cover 209 is closed. A filter screen 207 is fixedly connected to the top of the filter frame 203 to perform preliminary filtration of the liquid entering the filter box 201. Multiple filter cotton 208s are provided in the middle of the inner wall of the fixing seat 202. A sealing cover 209 is rotatably connected to the top of the filter box 201, which can be rotated to open or close the filter box 201. A conveying pipe 210 is connected to the top of the sealing cover 209.

[0034] Specifically, the filter box 201 is the filtration site. The fixing seats 202 at the four corners of the inner wall cooperate with the positioning pins 204 at the four corners of the bottom of the filter frame 203. The positioning pins 204 engage with the positioning grooves 205 at the top of the fixing seats 202, allowing the filter frame 203 to slide stably on the inner wall of the filter box 201, facilitating installation and disassembly. The filter screen 207 fixed at the top of the filter frame 203 is responsible for the initial filtration of the liquid, intercepting larger particles of impurities. Multiple filter cottons 208 located in the middle of the inner wall of the fixing seats 202 then perform secondary filtration on the liquid that has been initially filtered by the filter screen 207. Fine filtration further removes fine impurities, ensuring the purity of the liquid entering the vacuum tank 1. The sealing ring 206 fixed on the top of the filter box 201 ensures the airtightness of the filter box 201 when the sealing cover 209 is closed, preventing liquid leakage. When the filter cotton 208 may affect the filtration effect due to excessive impurities, the sealing cover 209 can be rotated open. By separating the positioning pin 204 from the positioning groove 205, the filter frame 203 can be easily removed, facilitating the replacement of the filter cotton 208 in the fixed seat 202. This maintains the good filtration performance of the filter mechanism 2 and ensures the smooth progress of the entire degassing process.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A base 19 is fixedly connected to the bottom of the heating plate 10. Multiple bolts 20 are threaded around the bottom of the base 19. The base 19 can securely install the heating plate 10 in the designated position through the bolts 20 threaded around the bottom, ensuring its stability during operation. A mounting box 21 is fixedly connected to the top of the front side of the outer wall of the heating plate 10. An alarm light 22 is fixedly connected to the inner wall of the mounting box 21. The alarm light 22 is used to issue a warning when the heating plate 10 malfunctions, reminding the operator to handle the situation in time.

[0036] Specifically, the base 19 at the bottom of the heating plate 10 can be securely installed in a designated position by bolts 20 connected by threads around the perimeter, ensuring its stability during operation. The alarm light 22 installed in the mounting box 21 on the top front side of the outer wall of the heating plate 10 is used to issue a warning when the heating plate 10 malfunctions, reminding the operator to handle the situation in time and ensuring the safety of the equipment and the normal operation of the degassing process.

[0037] Reference Figure 1 , Figure 2 and Figure 5An information panel 23 is installed on the front side of the outer wall of the filter box 201 to record filtration-related information for easy viewing by operators. Screws 24 are threaded at the four corners of the outer wall of the information panel 23, and the rear ends of the screws 24 are threaded to the filter box 201. Fasteners 25 are fixedly connected to the left and right sides of the front end of the outer wall of the sealing cover 209, and hooks 26 are fixedly connected to the left and right sides of the front end of the outer wall of the filter box 201. The two hooks 26 engage with the corresponding fasteners 25, and the fasteners 25 engage with the hooks 26 on the filter box 201 to achieve a seal and facilitate opening and closing. Support legs 27 are fixedly connected to the left and right sides of the bottom of the filter box 201, and reinforcing ribs 3 are fixedly connected to the inner walls of the two support legs 27 to ensure that the filter box 201 is stable during use and to ensure normal filtration operation.

[0038] Specifically, the information board 23 is fixed by screws 24 connected by four corner threads and is used to record filtration-related information for easy viewing by operators. The sealing cover 209 is engaged with the hooks 26 on the filter box 201 by the latches 25 on the left and right sides of the front end, achieving a seal and facilitating opening and closing.

[0039] Working principle: First, the liquid to be degassed enters the vacuum tank 1 through the feed pipe 12. The control valve 14 on the outer wall of the feed pipe 12 controls the inflow of liquid, ensuring that an appropriate amount of liquid enters the tank. After the liquid enters the vacuum tank 1, the heating wire 11 inside the heating plate 10 starts to work. The heating plate 10 surrounds the outer wall of the vacuum tank 1, which can evenly heat the liquid inside the tank. By increasing the liquid temperature, the movement speed of gas molecules is accelerated, making it easier for the gas to separate from the liquid. At the same time, the vacuum pump 4 starts and draws air out of the vacuum tank 1 through the suction pipe 5, gradually creating a vacuum environment inside the tank. Under vacuum conditions, the solubility of gas in liquid decreases, further promoting the escape of gas from the liquid. While heating and vacuum creation are underway, the motor 6 drives the stirring rod 7, which is fixed to its outer wall. Multiple stirring blades 8 on the lower side rotate. The turbulence holes 9 on the surface of the stirring blades 8 not only promote the circulation of liquid during rotation, but also disturb the liquid flow state, making the liquid more uniformly mixed. This ensures that the liquid in each part can be fully heated and contact the vacuum environment, avoiding insufficient local degassing. After preliminary degassing, the liquid enters the degassing component through the discharge pipe 13. The control valve 14 on the discharge pipe 13 controls the liquid flow. The connecting pipe 15 connects the discharge pipe 13 to the diaphragm pump 16. The diaphragm pump 16 provides power to transport the liquid to the membrane stripper 17. The membrane stripper 17 further processes the liquid, allowing the residual gas to pass through a special membrane structure and return to the vacuum tank 1 through the pipe 18, where it is pumped away by the vacuum pump 4. The liquid that has undergone deep degassing can be discharged from the discharge pipe 13.

[0040] Before entering the vacuum tank 1, the liquid first flows through the conveying pipe 210 and then through the filter mechanism 2. The rear end of the filter box 201 of the filter mechanism 2 is connected to the front end of the discharge pipe 13 to ensure that the liquid can flow smoothly into the filter box 201. After entering the filter box 201, the liquid first undergoes preliminary filtration through the filter screen 207. The filter screen 207 is fixed to the top of the filter frame 203 and can intercept larger particulate impurities in the liquid. The filter frame 203 is engaged with the positioning pins 204 at the four corners of the bottom and the positioning grooves 205 at the top of the fixing seats 202 at the four corners of the inner wall of the filter box 201 through the positioning pins 204 at the four corners of the bottom, so as to achieve precise positioning and stable installation, and facilitate disassembly. The liquid that has undergone preliminary filtration continues to flow downward and then passes through multiple filter cotton 208s set in the middle of the inner wall of the fixing seat 202. The filter cotton 208 performs secondary fine filtration on the liquid, further intercepting smaller impurities, ensuring that the liquid entering the vacuum tank 1 has a higher purity. The sealing ring 206 can effectively prevent liquid leakage when the sealing cover 209 is closed, ensuring that the filtration process is carried out in a closed environment.
