Description

Technical Field

[0001] This utility model relates to the field of vacuum degassing instrument technology, and in particular to an improved vacuum degassing instrument. Background Technology

[0002] Vacuum degassing instruments play a role in separating gases from solutions in various industries. Their function is to degas distilled water and deionized water. In chemical experiments and production, the degassed water is used for reactions or as a solvent, improving the accuracy of chemical reactions and product quality. The device replaces the traditional manual boiling method, improving work efficiency and saving manpower and time costs, making it a device for modern industrial production and scientific research experiments.

[0003] Existing vacuum degassing instruments employ a combination of heating, circulation, and vacuuming. Heating reduces the solubility of gases in water, a circulation system allows the water to flow freely, and a vacuum pump extracts the gases to achieve degassing. The instrument has a liquid storage chamber to hold the liquid to be treated, connecting pipes handle the inlet and outlet of the liquid, and the vacuum pump creates a vacuum environment. All components work together to complete the degassing process.

[0004] Existing vacuum degassing instruments have many problems. They rely on gaskets to seal the connections between components, preventing gas leakage and ensuring the stability of the vacuum environment. However, due to frequent liquid additions and device maintenance, the gaskets are subjected to friction and compression. After long-term use, the gaskets will wear and deform. During the vacuuming stage, external air can enter the instrument through gaps, causing the vacuum level to fail to reach the set standard. Insufficient vacuum prevents gas from escaping from the water, affecting the degassing effect and product quality. This necessitates repeating the production process, severely impacting the efficiency and economy of production and experimentation. Utility Model Content

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.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an improved vacuum degassing device, comprising a base plate 1, which serves as a support. A base 3 is fixedly connected to the top of the base plate 1, serving to support and fix components. A slot 4 is provided inside the base 3, facilitating the installation and positioning of a vacuum tank 6 and a shell 7. A sealing gasket 5 is fixedly connected to the bottom inner side of the base 3, enhancing the seal between the vacuum tank 6 and the base 3. A vacuum tank 6 is fixedly connected to the inner side of the sealing gasket 5 and one side of the slot 4, serving as a degassing reaction vessel. A shell 7 is fixedly connected to the outer side of the sealing gasket 5 and one side of the slot 4, protecting internal components and enhancing overall structural stability. Bolts 8 are fixedly connected around the outer wall of the base 3, with one end of each bolt 8 penetrating the vacuum tank 6 and the shell 7, tightening the connection between the vacuum tank 6 and the shell 7 for a more secure connection. A feed pipe 9 is connected to the top right side of the shell 7, introducing the material to be degassed into the vacuum tank 6. The left end of the feed pipe 9 penetrates the shell 7 and connects to the vacuum tank 6. The inner wall of the housing 7 is fixedly connected to the bottom of the feed pipe 9, and a self-priming pump 10 is fixedly connected to the bottom of the feed pipe 9. The self-priming pump 10 can automatically suck up materials and transport them to the vacuum tank 6 through the feed pipe 9. The bottom of the self-priming pump 10 is fixedly connected to the top right side of the base plate 1 to provide support for the self-priming pump 10. A pressure gauge 11 is fixedly connected to the top of the housing 7. The pressure gauge 11 is used to monitor the pressure inside the vacuum tank 6 in real time. The bottom of the pressure gauge 11 penetrates the housing 7 and is fixedly connected to the top inner wall of the vacuum tank 6. An exhaust pipe 12 is connected to the front of the pressure gauge 11. 2 is used to discharge the gas removed from the vacuum tank 6. The bottom of the base 3 is fixedly connected to the motor 13, which provides power to the stirrer 14. The output end of the motor 13 passes through the interior of the base 3 and is rotatably connected to the stirrer 14. The stirrer 14 stirs the material in the vacuum tank 6 under the drive of the motor 13, which accelerates the degassing speed. The top front left side of the base plate 1 is provided with a purification mechanism 2. The purification mechanism 2 is used to improve the safety of the discharge. The purification mechanism 2 can effectively purify the harmful components in the gas discharged from the exhaust pipe 12 and reduce environmental pollution.

[0033] Specifically, when the improved vacuum degasser is started, the self-priming pump 10 begins operation, automatically drawing in the material to be degassed. The material is transported from the self-priming pump 10 to the vacuum tank 6 via the feed pipe 9. The left end of the feed pipe 9 passes through the outer shell 7 and is flush with the inner wall of the vacuum tank 6, ensuring that the material enters the vacuum tank 6 accurately. The vacuum tank 6 is the degassing reaction vessel, installed in the slot 4 inside the base 3. The slot 4 facilitates the installation of the vacuum tank 6 and enhances the sealing effect. The sealing gasket 5 on the bottom inner side of the base 3 fits tightly between the vacuum tank 6 and the base 3, enhancing the sealing performance and preventing gas leakage. The outer shell 7 is also installed in the slot 4, located outside the sealing gasket 5, which not only protects the internal components but also enhances the stability of the overall structure. One end of the bolts 8 around the outer wall of the base 3 passes through the vacuum tank 6 and the outer shell 7, firmly fixing the outer shell 7, the sealing gasket 5, and the vacuum tank 6 to the base. In base 3, the sealing of vacuum tank 6 is improved. Motor 13 is located at the bottom of base 3, and its output end passes through the inside of base 3 and is connected to stirrer 14. Motor 13 provides power to stirrer 14. When motor 13 is running, it drives stirrer 14 to stir the material in vacuum tank 6. Through stirring, the material can come into more full contact with the vacuum environment, thereby accelerating the degassing speed. During the degassing process, the pressure in vacuum tank 6 is monitored in real time by pressure gauge 11 on the top of outer shell 7. The front side of pressure gauge 11 is connected to exhaust pipe 12, through which the degassed gas is discharged. Purification mechanism 2 is located at the top front left end of base plate 1. It is mainly used to decompose harmful molecules in the gas discharged from exhaust pipe 12. After the gas is discharged from exhaust pipe 12, it enters purification mechanism 2. Purification mechanism 2 treats the harmful components in the gas, effectively reducing environmental pollution and improving the safety of emissions.

[0034] Reference Figure 1 , Figure 2 and Figure 3The purification mechanism 2 includes a reaction chamber 201, which is used to contain the container during the purification process. The bottom of the reaction chamber 201 is fixedly connected to the top front left end of the base plate 1. A water pump 202 is fixedly connected to the top left side of the reaction chamber 201. The water pump 202 is used to extract the liquid in the reaction chamber 201 and transport it to subsequent components, realizing liquid circulation to participate in the purification reaction. A water suction pipe 203 is connected to the left side of the water pump 202. The water suction pipe 203 is used to extract the liquid at the bottom of the reaction chamber 201 to the water pump 202. The bottom end of the water suction pipe 203 is connected to the bottom left side of the reaction chamber 201. A water outlet pipe 204 is connected to the front side of the water pump 202. The water outlet pipe 204 is used to output the liquid extracted by the water pump 202 to the water distribution pipe 205. The bottom end of the water outlet pipe 204 is fixedly connected to the water distribution pipe 205. The liquid can be evenly distributed to each sprayer 206, ensuring that the purified liquid can fully cover the gas to be purified. Multiple sprayers 206 are fixedly connected to the rear side of the water distribution pipe 205. The sprayers 206 atomize the liquid and spray it out, which fully contacts the gas entering the reaction chamber 201, thereby purifying the harmful components in the gas. An inclined plate 207 is fixedly connected to the bottom of the reaction chamber 201. The inclined plate 207 facilitates the flow of the liquid after the reaction to a specific position, which is conducive to the collection and recycling of the liquid. Baffles 208 are fixedly connected to the top left and right sides of the inclined plate 207. The baffles 208 are used to slow down the flow speed of the gas and increase the purification reaction time. An exhaust port 209 is connected to the top left side of the reaction chamber 201. The exhaust port 209 is used to discharge the purified gas from the reaction chamber 201 and release it into the external environment.

[0035] Specifically, after degassing is completed, the waste gas enters the reaction chamber 201 through the exhaust pipe 12. The water pump 202 starts working, drawing liquid from the bottom of the reaction chamber 201 to the water pump 202 through the water suction pipe 203 connected to the left side. After being pressurized by the water pump 202, the liquid drawn by the water pump 202 is output to the water distribution pipe 205 through the water outlet pipe 204. The water distribution pipe 205 can evenly distribute the liquid to each sprayer 206, ensuring that the purified liquid can fully cover the gas to be purified. The sprayers 206 atomize the liquid and spray it out powerfully, making full contact with the gas entering the reaction chamber 201. The purified components in the liquid react with the harmful components in the gas. The reaction occurs, thereby purifying harmful components in the gas. The inclined plate 207 at the bottom of the reaction chamber 201 allows the reacted liquid to flow smoothly to the bottom of the reaction chamber 201, facilitating collection and recycling. The baffles 208 on the left and right sides of the top of the inclined plate 207 slow down the gas flow rate, allowing the gas to have more time to contact the atomized liquid in the reaction chamber 201, thus enhancing the purification reaction time. After purification, the gas is discharged from the reaction chamber 201 through the exhaust port 209, allowing it to be released into the external environment. This achieves effective purification of the emitted gas during the degassing process of the improved vacuum degassing instrument, reducing environmental pollution.

[0036] Reference Figure 1 , Figure 2 and Figure 4 A sealing hole 15 is provided on the left side of the outer wall of the outer shell 7. The sealing hole 15 is used to install the sealer 16 to ensure the sealing of the device. The sealer 16 is fixedly connected to the inner wall of the sealing hole 15. The sealer 16 is used to seal the feed pipe 9 and the discharge pipe 24. The inner wall of the sealer 16 is fixedly connected to the left outer wall of the feed pipe 9. The feed pipe 9 is used to transport materials into the vacuum tank 6. Multiple heaters 17 are fixedly connected to the outer wall of the vacuum tank 6. The heaters 17 can heat the materials in the vacuum tank 6. A control box 18 is fixedly connected to the top left end of the rear side of the base 3. The control box 18 is used to control the operation of heating. A pressure gauge 19 is fixedly connected to the top front side of the outer shell 7. The pressure gauge 19 monitors the pressure inside the outer shell 7 and outside the vacuum tank 6 in real time. Multiple indicator lights 20 are fixedly connected to the top of the outer shell 7. The indicator lights 20 can show whether the pressure is normal.

[0037] Specifically, when material enters the vacuum tank 6 through the feed pipe 9, the outer wall of the left side of the feed pipe 9 is connected to the inner wall of the sealer 16. The sealer 16 is installed in the sealing hole 15 on the left side of the outer wall of the outer shell 7 to ensure the sealing of the device during material conveying and prevent outside air from entering. After the material enters the vacuum tank 6, multiple heaters 17 installed on the outer wall of the vacuum tank 6 work as needed to heat the material in the tank and increase the degassing speed. The control box 18 located at the top left of the rear side of the base 3 controls the operation of the heaters 17 and precisely adjusts the heating power and time. The pressure detection gauge 19 on the top front side of the outer shell 7 monitors the pressure inside the outer shell 7 and outside the vacuum tank 6 in real time. Once the pressure is abnormal, the multiple indicator lights 20 on the top change from the normal green light to a red warning light to remind the staff to deal with it in time, ensuring the safe and stable operation of the device and efficiently completing the processing task of the material in a vacuum and heating environment.

[0038] Reference Figure 1 , Figure 2 and Figure 3A material pump 23 is fixedly connected to the top left side of the base plate 1. The material pump 23 can extract the degassed liquid in the vacuum tank 6. The right side of the material pump 23 is connected to the discharge pipe 24, which transports the material extracted by the material pump 23 to achieve directional material transmission. The right end of the discharge pipe 24 passes through the outer shell 7 and connects to the left side of the inner wall of the vacuum tank 6. A control box 25 is fixedly connected to the top front side of the base plate 1. The control box 25 plays a role in protecting and organizing the wiring. A controller 26 is fixedly connected to the front side of the control box 25. The controller 26 controls and adjusts the operating parameters and functions of the device to realize intelligent operation of the device. A protective pad 21 is fixedly connected to the left side of the outer wall of the exhaust port 209. The protective pad 21 plays a role in buffering and protecting the exhaust port 209 from collision damage. A filter screen 22 is fixedly connected to the inner wall of the exhaust port 209. The filter screen 22 can filter the exhaust gas to prevent impurities and particulate matter from being discharged and causing environmental pollution.

[0039] Specifically, the pump 23 mainly extracts the degassed liquid from the vacuum tank 6. When the device is started, the pump 23 begins to work, drawing the degassed liquid from the vacuum tank 6 into the pump body. The discharge pipe 24 is connected to the right side of the pump 23, conveying the material extracted by the pump 23. Under the power of the pump 23, the material is directionally transported along the discharge pipe 24, ensuring that the liquid can flow out smoothly. The control box 25 is located on the top front side of the base plate 1, and various electrical components and wiring are centrally located inside, serving to protect and organize the wiring, preventing messy wiring from causing problems. To prevent malfunctions and safety hazards, the controller 26 controls and adjusts the operating parameters and functions of the device to achieve intelligent operation. The protective pad 21 on the outer wall of the exhaust port 209 acts as a buffer and protector. When the exhaust port 209 comes into contact with or collides with a component, the protective pad 21 can absorb the impact force and prevent damage to the exhaust port 209. The filter screen 22 on the inner wall of the exhaust port 209 filters the exhaust gas, effectively intercepting impurities and particulate matter in the gas, preventing pollutants from being discharged from the device and causing environmental pollution, while avoiding impact on surrounding devices and personnel.

[0040] Working Principle: When the improved vacuum degasser is started, the self-priming pump 10 begins operation, automatically drawing in the material to be degassed. The material is transported from the self-priming pump 10 to the vacuum tank 6 via the feed pipe 9, ensuring accurate entry of the material into the vacuum tank 6. The vacuum tank 6 serves as the degassing reaction vessel. The slot 4 enhances the installation and sealing effect of the vacuum tank 6. The sealing gasket 5 on the inner bottom of the base 3 fits tightly between the vacuum tank 6 and the base 3, enhancing the seal and preventing gas leakage. The outer shell 7 is also installed in the slot 4, located outside the sealing gasket 5, protecting the internal components and enhancing the overall structure. To improve structural stability, one end of bolt 8 passes through the vacuum tank 6 and the outer shell 7, firmly fixing the outer shell 7, sealing gasket 5, and vacuum tank 6 in the base 3, thereby improving the sealing performance of the vacuum tank 6. The output end of motor 13 is connected to agitator 14, and motor 13 provides power to agitator 14. When motor 13 is running, it drives agitator 14 to stir the material inside the vacuum tank 6. Through stirring, the material can come into more full contact with the vacuum environment, thereby accelerating the degassing speed. During the degassing process, the pressure inside the vacuum tank 6 is monitored in real time by pressure gauge 11 on the top of the outer shell 7. After degassing is completed, the material is discharged through exhaust pipe 12.

[0041] After degassing is complete, the waste gas enters the reaction chamber 201 through the exhaust pipe 12. The water pump 202 starts working, and the water suction pipe 203 draws the liquid from the bottom of the reaction chamber 201 to the water pump 202. After being pressurized by the water pump 202, the liquid drawn by the water pump 202 is output to the water distribution pipe 205 through the water outlet pipe 204. The water distribution pipe 205 can evenly distribute the liquid to each sprayer 206, ensuring that the purified liquid can fully cover the gas to be purified. The sprayers 206 atomize the liquid and spray it out powerfully, making full contact with the gas entering the reaction chamber 201. The purified components in the liquid react with the components in the gas. Harmful components react, thereby purifying the harmful components in the gas. The inclined plate 207 allows the reacted liquid to flow smoothly to the bottom of the reaction chamber 201, facilitating collection and recycling. The baffle 208 slows down the gas flow rate, allowing the gas to have more time to contact the atomized liquid in the reaction chamber 201, enhancing the purification reaction time. After purification, the gas is discharged from the reaction chamber 201 through the exhaust port 209, allowing it to be released into the external environment. This achieves effective purification of the emitted gas during the degassing process of the improved vacuum degasser, reducing environmental pollution.
