Description

Technical Field

[0001] This utility model relates to the field of exhaust gas cooling and absorption technology, specifically to a vacuum pump exhaust gas cooling and absorption device. Background Technology

[0002] When a vacuum pump is working, it generates mechanical work, which produces heat in the process. This heat is generated by thermal conduction between molecules in the discharged gas, and it also depends on the type of vacuum pump. For example, rotary vacuum pumps typically produce a large amount of hot gas, while diffusion vacuum pumps produce relatively less. To prevent high temperatures from damaging the pump body, air or other gases are usually used for cooling and purification to lower the temperature. Therefore, the gas discharged by a vacuum pump is hot.

[0003] A search revealed that Chinese Patent CN219914024U, published on October 27, 2023, discloses an exhaust gas cooling device, comprising: a quartz reaction tube, a cooling mechanism connected to the quartz reaction tube, and a vacuum pump connected to the cooling mechanism. The cooling mechanism includes a cooling box and a cooling component disposed within the cooling box. The upper end of the cooling box has a cooling medium inlet, and the lower end of the cooling box has a cooling medium outlet. The cooling component is a spiral metal tube disposed within the cooling box. The inlet of the spiral metal tube is connected to the outlet of the quartz reaction tube, and the outlet of the spiral metal tube is connected to the inlet of the vacuum pump. The cooling medium inlet injects a constant-temperature cooling medium into the cooling box to cool the exhaust gas entering the spiral metal tube. This exhaust gas cooling device has a simple structure, can extend the service life of the vacuum pump and the spiral tube, and reduce the maintenance frequency of the vacuum pump and the difficulty of installing accessories.

[0004] The above structure also has the following drawbacks:

[0005] Existing absorption devices are inconvenient to agitate the water on the outside of the spiral metal tube during use, resulting in poor cooling effect when cooling exhaust gas. At the same time, condensate remains inside the spiral metal tube and cannot be collected and discharged, which even causes some trouble for the overall device. Therefore, there is an urgent need for a vacuum pump exhaust gas cooling absorption device to overcome the above defects. Utility Model Content

[0006] The present invention aims to solve the problems mentioned in the background art by providing a vacuum pump exhaust gas cooling and absorption device.

[0007] The specific technical solution is as follows:

[0008] A vacuum pump exhaust gas cooling and absorption device includes a base, a purified exhaust box fixedly installed on the left side of the top of the base, a condensate collection box fixedly installed on the right side of the top of the base, a refrigeration box fixedly installed on the top of the condensate collection box, a spiral transfer tube provided in the inner cavity of the refrigeration box, and a stirring frame rotatably connected to both sides of the bottom of the inner cavity of the refrigeration box via bearings. A uniformly distributed purified filter element is fixedly installed in the inner cavity of the purified exhaust box. A first single pulley is provided on the left side of the top of the refrigeration box, a double pulley is provided on the right side of the top of the refrigeration box, a motor is fixedly installed on one side of the top of the refrigeration box, a second single pulley is fixedly installed on the top of the motor, and a connecting pipe is connected to the back of the condensate collection box, with a float frame provided inside the connecting pipe.

[0009] In the aforementioned vacuum pump exhaust gas cooling and absorption device, the top right side of the purified exhaust box is connected to the top left side of the condensate collection box via a gas guide pipe, and the bottom of the spiral transfer pipe is connected to the top of the condensate collection box.

[0010] In the aforementioned vacuum pump exhaust gas cooling and absorption device, a drain valve is connected to the right side of the condensate collection tank, and the top of the stirring rack on the left side extends through to the top of the refrigeration box and is fixedly connected to the bottom of the first single pulley.

[0012] In the aforementioned vacuum pump exhaust gas cooling and absorption device, the surface of the second single pulley is connected to the top of the surface of the double pulley via belt drive, and an installation frame is fixedly installed on the top of the inner cavity of the condensate collection tank.

[0013] In the aforementioned vacuum pump exhaust gas cooling and absorption device, a spring is fixedly installed at the bottom of the inner cavity of the mounting frame, and a sealing plate is fixedly installed at the top of the spring.

[0016] This utility model has the following beneficial effects:

[0017] The vacuum pump exhaust gas cooling and absorption device provided by this utility model installs a purified exhaust box and a condensate collection box on a base. A purified filter element is installed in the purified exhaust box to filter and purify the exhaust gas. A cooling box cools the coolant. A motor drives a second single pulley. A spiral transfer tube facilitates exhaust gas cooling. The condensate collection box stores the condensate. In use, the vacuum pump is connected to the front of the spiral transfer tube. The cooling box is then turned on to cool the coolant. The motor is then turned on, driving the double pulleys and the first single pulley to rotate, causing the stirring frame to agitate the coolant. When the pump generates exhaust gas, the gas enters the spiral transfer tube. The gas is cooled by the coolant inside the cavity. The pressure of the gas causes the sealing plate to move downwards along with the spring, allowing condensate to enter the condensate collection tank. The gas then further enters the purified exhaust tank and is purified by the filter element before being discharged through the purified exhaust tank. As the condensate in the collection tank increases, the buoy moves upwards, alerting the operator. This design offers advantages such as good cooling performance and convenient condensate collection. It solves the problems of existing absorption devices where stirring the water outside the spiral metal tube is inconvenient, resulting in poor cooling of the exhaust gas and condensate residue remaining inside the spiral metal tube, causing problems for the entire device.

A float frame 17 is provided inside the connecting pipe 16.

[0030] More specifically, condensate is stored in a condensate collection tank 3. During use, a vacuum pump is connected to the front of the spiral transfer tube 5. Then, the cooling box 4 is turned on to cool the coolant. Next, the motor 8 is turned on, driving the double pulley 6 and the first single pulley 7 to rotate, causing the stirring frame 10 to stir the coolant. When the pump produces exhaust gas, the gas enters the inner cavity of the spiral transfer tube 5 and is cooled by the coolant. Because of the gas pressure, the sealing plate 14 causes the spring 13 to move downwards, allowing condensate to enter the inner cavity of the condensate collection tank 3. The gas then further enters the inner cavity of the purification exhaust box 2 and is purified by the purification filter element 15 before being discharged through the purification exhaust box 2. As the condensate in the condensate collection tank 3 gradually increases, the buoy frame 17 moves upwards, thus alerting the operator. This system has the advantages of good cooling effect and convenient condensate collection.

[0031] In some embodiments, the top right side of the purified exhaust box 2 is connected to the top left side of the condensate collection box 3 via an air guide pipe, and the bottom of the spiral transfer pipe 5 is connected to the top of the condensate collection box 3. More specifically, by setting the spiral transfer pipe 5 and the condensate collection box 3 together, it is convenient to discharge the condensate.

[0032] In some embodiments, a drain valve 11 is connected to the right side of the condensate collection tank 3, and the top of the left stirring rack 10 extends through to the top of the refrigeration box 4 and is fixedly connected to the bottom of the first single pulley 7. More specifically, the drain valve 11 is provided to facilitate the discharge of condensate from the condensate collection tank 3.

[0033] In some embodiments, the surface of the first single pulley 7 is connected to the bottom of the surface of the double pulley 6 by a belt drive, and the top of the right stirring rack 10 extends through to the top of the refrigeration box 4 and is fixedly connected to the bottom of the double pulley 6. More specifically, the double pulley 6 drives the first single pulley 7 and drives the stirring rack 10 at the same time.

[0034] In some embodiments, the surface of the second single pulley 9 is connected to the top of the surface of the double pulley 6 by belt drive, and the top of the inner cavity of the condensate collection tank 3 is fixedly installed with an installation frame 12. More specifically, the double pulley 6 is driven by the second single pulley 9.

[0035] In some embodiments, a spring 13 is fixedly installed at the bottom of the inner cavity of the mounting frame 12, and a sealing plate 14 is fixedly installed at the top of the spring 13. More specifically, the spring 13 is installed by setting the mounting frame 12, and the sealing plate 14 is reset by setting the spring 13.

[0036] In some embodiments, the top of the purification exhaust box 2 is fixedly connected to the left side of the bottom of the refrigeration box 4, and the inside of the buoy frame 17 is provided with a sliding groove 18. More specifically, the bottom of the spiral transmission pipe 5 is blocked by setting a sealing plate 14, and the buoy frame 17 is used to remind the staff.

[0037] In some embodiments, a slider 19 is slidably connected inside the chute 18, and the two sides of the slider 19 are fixedly connected to the inner cavity of the connecting pipe 16.

[0038] In use, flanges are installed at the vacuum pump outlet and the spiral transfer tube inlet, respectively, and the two are tightly connected together using bolts and gaskets. Then, the cooling box 4 is opened to cool the coolant. Next, the motor 8 is turned on, which drives the double pulley 6 and the first single pulley 7 to rotate, causing the stirring frame 10 to stir the coolant. When the pump produces exhaust gas, the gas enters the inner cavity of the spiral transfer tube 5 and is cooled by the coolant. Because of the gas pressure, the sealing plate 14 moves the spring 13 downward, and the condensate enters the inner cavity of the condensate collection tank 3. Then, the gas further enters the inner cavity of the purification exhaust box 2 and is purified by the purification filter element 15. Finally, it is discharged through the purification exhaust box 2. As the condensate in the inner cavity of the condensate collection tank 3 gradually increases, the float frame 17 moves upward, thus alerting the staff. It has the advantages of good cooling effect and convenient collection of condensate.
