Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a vacuum degassing device with automatic sealing. Background Technology

[0002] Vacuum degassing devices are precision instruments used to efficiently remove dissolved gases and microbubbles from liquid or semi-solid materials. The core features of these devices are the installation of a closed-loop control mechanism and a dynamic sealing component. A negative pressure environment is established by a vacuum pump group, and a temperature control component accelerates the gas escape rate. At the same time, a pressure sensor monitors the state of the chamber in real time, and a sealing mechanism prevents the backflow of outside air from causing contamination. In particular, the performance of vacuum degassing devices with automatic sealing function directly affects the density, optical properties, and mechanical strength of the final product, and therefore they are welcomed in the synthesis of polymer materials and biopharmaceutical processes.

[0003] Although vacuum degassing devices with automatic sealing have a wide range of applications, there are cleaning dead zones in the corners or complex parts of the degassing chamber. After the degassing process, residual material in the corners, gaps, and around parts that are not easy to disassemble is difficult to clean thoroughly. Long-term accumulation will affect the performance of the equipment and the quality of the material. The existing solution is to design the degassing chamber to be easy to disassemble, reduce the internal corners and gaps, and use online cleaning nozzles to thoroughly clean the chamber. However, it is still impossible to completely remove stubborn stains or impurities that have accumulated in the tiny gaps. Furthermore, frequent disassembly of parts will lead to damage to the parts or a decrease in sealing performance. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, external clean water is drawn out and pressurized by a pressure pump, and the pressurized water is sprayed out from a rotating nozzle to perform preliminary cleaning of the inner wall of the degassing tank. Then, the servo motor is started so that the cleaning brush can rotate around the axis of the rotating shaft to thoroughly clean the inner wall of the degassing tank. In addition, the spring enables the cleaning brush to continuously clean the degassing tank, increasing the service life of the cleaning brush. The high-pressure clean water and the cleaning brush work together to ensure that the inner wall of the degassing tank can be thoroughly cleaned.

[0022] 2. In this utility model, the high-pressure air in the compressed air tank is opened by opening the quick inflation valve through the control panel, allowing the air to enter the air bladder. This causes the air bladder to expand rapidly, blocking the water inlet pipe and creating a closed environment inside the degassing tank. After degassing is completed, the quick release valve is opened to release the air inside the air bladder to the outside. This not only prevents the released air from contaminating the degassed material but also allows the air pressure in the degassing tank to be rebalanced. The elastic deformation of the air bladder ensures the automatic sealing effect of the device. Furthermore, the structure is simple and easy to operate. Attached Figure Description

[0032] 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.

[0033] Reference Figure 2 , Figure 5 and Figure 6This utility model provides an embodiment of a vacuum degassing device with automatic sealing, comprising a device box 1 and a degassing tank 2. A servo motor 4 is fixedly connected to the bottom of the outer wall of the degassing tank 2, providing power for the rotation of a rotating shaft 5. The output end of the servo motor 4 is fixedly connected to the rotating shaft 5, which transmits power and connects the servo motor 4 and an electric push rod 6. The top end of the rotating shaft 5 is fixedly connected to the electric push rod 6, which enables the cleaning brush 10 to move up and down. The top end of the electric push rod 6 is fixedly connected to... The device includes a brush handle 7 for mounting a cleaning brush 10. Slide grooves 8 are provided on both the left and right sides of the brush handle 7, providing space for the cleaning brush 10. Multiple springs 9 are fixedly connected to the inner walls of both slide grooves 8, ensuring the cleaning brush 10 remains in close contact with the inner wall of the degassing tank 2. The cleaning brush 10 is slidably connected to the inner walls of both slide grooves 8 for cleaning the inner wall of the degassing tank 2. Multiple limiting blocks 11 are fixedly connected to the inner walls of both slide grooves 8 to prevent the cleaning brush 10 from sliding out. A pressure pump 12 is fixedly connected to the bottom of the inner wall of the chute 8 and the equipment box 1. The front of the pressure pump 12 is connected to an external water source, which can draw in clean water and pressurize it. A water supply pipe 13 is fixedly connected to the top of the pressure pump 12. The water supply pipe 13 is used to transport the pressurized clean water. An annular water box 14 is fixedly connected to the top of the inner wall of the degassing tank 2. The annular water box 14 is used to transfer clean water. Multiple rotating nozzles 15 are threaded to the bottom of the annular water box 14. The pressurized clean water is sprayed out through the multiple rotating nozzles 15, and they can rotate on their own. The inner wall of the degassing tank 2 is thoroughly cleaned. An ultrasonic sensor 16 is fixedly connected to the top of the inner wall of the degassing tank 2. The ultrasonic sensor 16 is used to detect the cleaning status of the dirt on the inner wall of the degassing tank 2. A water inlet pipe 17 is connected to the front side of the degassing tank 2. The water inlet pipe 17 is the part into which the substance to be degassed enters. A drain hole 18 is opened at the bottom of the inner wall of the degassing tank 2. The degassed substance is discharged from the degassing tank 2 through the drain hole 18. A sealing mechanism 3 is provided on the inner wall of the equipment box 1. The sealing mechanism 3 is used to block the opening of the water inlet pipe 17.

[0034] Specifically, before degassing, the front of the pressurizing pump 12 is correctly connected to an external water source to ensure that the water source can smoothly provide clean water for subsequent cleaning. The power supply to the equipment is turned on, and the water inlet pipe 17 is opened. The material to be degassed is transported to the degassing tank 2 through the water inlet pipe 17. A vacuum environment is then created inside the degassing tank 2 to complete the degassing process. The pressurizing pump 12 is started, and it draws clean water from the external water source and pressurizes the water. The pressurized clean water is then transported to the annular water box 14 through the water delivery pipe 13. The annular water box 14 transfers the clean water to multiple rotating nozzles 15. The rotating nozzles 15 spray out the pressurized clean water while rotating on their own to perform a comprehensive preliminary rinse of the inner wall of the degassing tank 2. The servo motor 4 is then started and drives... Rotating shaft 5 causes electric push rod 6, brush handle 7, and cleaning brush 10 to move in a circular motion around the axis of rotating shaft 5, scrubbing the inner wall of degassing tank 2. Activating electric push rod 6 pushes brush handle 7 up and down, allowing cleaning brush 10 to scrub the inner wall of degassing tank 2 in both directions, ensuring thorough cleaning. During the movement of cleaning brush 10, spring 9 keeps it in close contact with the inner wall of degassing tank 2, guaranteeing the scrubbing effect. Limiting block 11 prevents cleaning brush 10 from slipping out of sliding groove 8. Ultrasonic sensor 16 can detect the cleaning status of dirt on the inner wall of degassing tank 2 in real time. After cleaning, wastewater in degassing tank 2 is discharged through drain hole 18.

[0035] Reference Figure 3 , Figure 4 and Figure 7 The sealing mechanism 3 includes a compressed air tank 301, which stores compressed air to provide air for the use of the airbag 304. The left end of the compressed air tank 301 is fixedly connected to the left side of the inner wall of the equipment box 1, and a vacuum tube 302 is fixedly connected to the middle of the right end of the compressed air tank 301. The vacuum tube 302 is used to transport compressed air. A fixing block 303 is fixedly connected to the front end of the inner wall of the degassing tank 2. The fixing block 303 can fix the position of the airbag 304 at the connection between the water inlet pipe 17 and the degassing tank 2, so that the airbag 304 can block the water inlet after it expands. An airbag 304 is fixedly connected to the right side of block 303. The airbag 304 blocks the water inlet, thus sealing the degassing tank 2. A quick inflation valve 305 is fixedly connected to the top of the airbag 304, which can quickly inflate the airbag 304. A quick deflation valve 306 is fixedly connected to the right end of the airbag 304, which can quickly deflate the airbag 304. An exhaust hose 307 is fixedly connected to the right end of the quick deflation valve 306, which connects to the outside and allows the air discharged from the airbag 304 to flow to the outside, thus avoiding any impact on the degassed material.

[0036] Specifically, when the material is transported to the degassing tank 2 through the water inlet pipe 17 to prepare for degassing, the quick inflation valve 305 is opened through the control panel 27. At this time, the compressed air in the compressed air storage tank 301 flows rapidly into the air bladder 304 through the vacuum pipe 302 under the action of pressure difference. As the compressed air is continuously filled, the air bladder 304 expands rapidly and, with its own elastic deformation, tightly adheres to the connection between the water inlet pipe 17 and the degassing tank 2, completely blocking the water inlet and preventing outside air from entering the degassing tank 2. This creates a closed vacuum environment in the degassing tank 2, ensuring that the degassing process is carried out without external interference. After the degassing process is completed, the quick release valve 306 is opened, and the compressed air in the air bladder 304 is quickly discharged to the outside through the exhaust hose 307 via the quick release valve 306. The air bladder 304 contracts rapidly under its own elasticity and external pressure, detaching from the connection between the water inlet pipe 17 and the degassing tank 2. The water inlet is reopened to facilitate subsequent material discharge and equipment cleaning operations.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Multiple rotating nozzles 15 are fixedly connected to threaded posts 22 at their top ends. Multiple threaded grooves 21 are provided at the bottom end of the annular water box 14. The threaded connection between the threaded posts 22 and the threaded grooves 21 allows for quick replacement and repair of the rotating nozzles 15 when damaged. A one-way valve 19 is fixedly connected to the inner wall of the drain hole 18. The one-way valve 19 prevents the discharged degassed material from flowing back. A sealing ring 20 is fixedly connected to the outer wall of the one-way valve 19, preventing outside air from entering the degassed tank 2. A pressure sensor 25 is fixedly connected to the front end of the compressed air storage tank 301. The pressure sensor 25 is used to detect the gas pressure inside the compressed air storage tank 301. A buzzer 26 is fixedly connected to the left side of the inner wall of the equipment box 1. The buzzer 26 can... An alarm is triggered when the value detected by the pressure sensor 25 is too low. An inspection door 23 is rotatably connected to the front of the equipment box 1. The components inside the equipment box 1 can be inspected through the inspection door 23. Two finger grooves 24 are opened on the front of the inspection door 23 to facilitate the opening of the inspection door 23. A pressure-reducing pad 28 is fixedly connected to the bottom of the equipment box 1. The pressure-reducing pad 28 can prevent the equipment box 1 from putting too much pressure on the ground. The pressure-reducing pad 28 is matched with the size of the equipment box 1. A control panel 27 is fixedly connected to the top of the inner wall of the equipment box 1. The control panel 27 is electrically connected to the servo motor 4, electric push rod 6, pressurization pump 12, ultrasonic sensor 16, rapid inflation valve 305, rapid deflation valve 306, pressure sensor 25 and buzzer 26 respectively.

[0038] Specifically, before using the equipment, the device can be connected to a mobile device via wireless technology, allowing operators to remotely control the servo motor 4, electric push rod 6, pressurizing pump 12, ultrasonic sensor 16, rapid inflation valve 305, rapid deflation valve 306, pressure sensor 25, and buzzer 26 via the mobile device, or via the control panel 27. Operators check the value of the pressure sensor 25 to confirm the gas pressure inside the compressed air tank 301. If the pressure sensor 25 detects a low value, the buzzer 26 sounds an alarm, reminding operators to inflate or inspect the compressed air tank 301. Multiple rotating nozzles 15 are inspected; if a damaged nozzle 15 is found, it is quickly replaced or repaired by rotating the threaded post 22 out of the threaded groove 21 at the bottom of the annular water box 14. The one-way valve 19 and sealing ring 20 are checked to ensure that the one-way valve 19 can function properly to prevent backflow of the degassed material and to prevent outside air from entering the degassing tank 2.

[0039] Working principle: The inlet pipe 17 serves as the material inlet. After opening, the material to be degassed flows into the degassing tank 2 under external force. The air inside the degassing tank 2 is then extracted to create a vacuum environment, allowing the gas to escape from the material, completing the degassing process and discharging it from the degassing tank 2. After the pressure pump 12 is powered on and started, it draws clean water from an external water source and increases the water pressure, giving the water greater kinetic energy. The pressurized clean water is then transported to the annular water box 14 via the water pipe 13, and the clean water is evenly distributed to multiple rotating nozzles 15. When the high-pressure clean water is sprayed, the rotating nozzles 15 rotate due to the reaction force, and the sprayed high-pressure water flow washes the inner wall of the degassing tank 2. The impact force of the water flow initially removes the dirt and residual material attached to the inner wall, expanding the cleaning coverage. The coverage area is expanded, improving cleaning efficiency. After the servo motor 4 is powered on, it drives the rotating shaft 5 to rotate. The rotating shaft 5 transmits the rotational power to the electric push rod 6, brush handle 7 and cleaning brush 10, causing the cleaning brush 10 to make a circular motion around the axis of the rotating shaft 5. At the same time, the electric push rod 6 pushes the brush handle 7 to move up and down. Under the action of circular motion and up and down movement, the cleaning brush 10 performs all-round brushing on the inner wall of the degassing tank 2. Meanwhile, the spring 9 keeps the cleaning brush 10 in close contact with the inner wall of the degassing tank 2, ensuring the brushing force and effect. The limit block 11 limits the movement range of the cleaning brush 10 to prevent the cleaning brush 10 from sliding out of the slide groove 8. The ultrasonic sensor 16 detects the cleaning status in real time. After cleaning is completed, the sewage is discharged through the drain hole 18 at the bottom of the inner wall of the degassing tank 2.

[0040] Furthermore, when it is necessary to seal the degassing tank 2 to begin the degassing operation, the operator opens the quick inflation valve 305 via the control panel 27. At this time, due to the higher pressure inside the compressed air storage tank 301 and the lower pressure inside the air bladder 304, compressed air quickly flows through the vacuum tube 302 to the air bladder 304. As compressed air continuously fills the air bladder 304, the pressure inside the air bladder 304 gradually increases. Because the air bladder 304 is made of a material with good elasticity, the air bladder 304 undergoes elastic deformation and expands rapidly. Due to the fixed block 3... 03. Fix the airbag 304 at the connection between the water inlet pipe 17 and the degassing tank 2. Therefore, the inflated airbag 304 fits tightly against the connection, thus completely blocking the water inlet. This allows the degassing tank 2 to form and maintain a closed vacuum environment. After the degassing process is completed, the operator opens the quick release valve 306. The compressed air in the airbag 304 is quickly discharged to the outside through the quick release valve 306 and the exhaust hose 307, causing the airbag 304 to contract quickly and reopen the water inlet, creating conditions for subsequent material discharge and equipment cleaning.
