Description

Technical Field

[0001] This utility model relates to the technical field of chemical machinery, specifically to an air extraction device for chemical machinery. Background Technology

[0002] In order to maintain the stability of the internal pressure of chemical equipment during production, it is necessary to use a gas extraction device to extract the gas inside the chemical equipment so that the production reaction can proceed.

[0003] A chemical machinery exhaust device disclosed in CN221525919U includes an exhaust box, a refrigeration conductor fixedly connected to the inner side wall of the exhaust box, a water collection box fixedly connected to the inner bottom wall of the exhaust box, a square tube fixedly connected to the top of the water collection box, an exhaust pipe fixedly connected to the top of the square tube, a water outlet pipe fixedly connected to the outer side wall of the exhaust pipe, a slide rail and a drain hole through the outer side wall of the water outlet pipe, a fixed seat fixedly connected to the inner side wall of the square tube, and a sliding column fixedly connected to the top of the fixed seat.

[0004] The aforementioned document can discharge the water accumulated at the bend of the exhaust pipe, preventing the condensate from accumulating for a long time and causing poor airflow inside the exhaust pipe, thereby avoiding a decrease in the efficiency of chemical heat gas emission.

[0005] However, the above-mentioned documents use filter boxes and filter plates to filter the extracted gas, but impurities in the gas will adhere to the filter screen, which will affect the filtration effect of the filter screen over time. At the same time, the above-mentioned use of "S"-shaped gas pipe for gas transmission requires additional equipment to treat the bottom of the "S", which is very troublesome and the gas guiding effect is poor. Therefore, we propose a gas extraction device for chemical machinery to solve the problems mentioned above. Utility Model Content

[0025] Please see Figure 1-6This utility model provides a technical solution: a vacuum pumping device for chemical machinery, comprising a movable base plate 1, a processing box 2, a vacuum pump 3, and a pressure pump 8. The processing box 2 is fixed above the movable base plate 1, and the vacuum pump 3 is fixed on the top of the processing box 2. A vacuum pipe 4 is provided on one side of the vacuum pump 3, and a control valve 5 is installed on the surface of the vacuum pipe 4. A semiconductor cooling chip 16 is fixed on the upper inner side of the processing box 2, and the semiconductor cooling chip 16 is arc-shaped. Three sets of semiconductor cooling chips 16 are arranged at equal angles inside the processing box 2, so that the device can be cooled by using the three sets of semiconductor cooling chips 16. The interior of the processing box 2 is fixed. An internal plate 17 is provided, which is staggered with the semiconductor cooling chip 16. Fans 18 are evenly installed on the surface of the internal plate 17 to facilitate the use of the fans 18 on the three internal plates 17, thereby improving the cooling effect of the device on the gas inside the gas guide tube 7. An exhaust pipe 6 is provided on the other side of the air pump 3. The exhaust pipe 6 passes through the upper surface of the processing box 2 and is connected to the gas guide tube 7 inside the processing box 2. The gas guide tube 7 is arranged in a spiral shape and is located outside the semiconductor cooling chip 16. The use of the spiral-shaped gas guide tube 7 allows the gas inside the gas guide tube 7 to be slowly discharged, which facilitates the cooling of the gas.

[0026] Please see Figure 1-6A sealing plate 10 is fixed at the bottom of the treatment box 2. The lower part of the air guide pipe 7 passes through the surface of the sealing plate 10. A pressure pump 8 is installed above one side of the exhaust pipe 6, and the output end of the pressure pump 8 is connected to the exhaust pipe 6 through a connecting pipe 9. A pull-out frame 11 is slidably connected to the bottom of the treatment box 2. A filter screen 12 and an activated carbon screen 13 are installed inside the pull-out frame 11. The filter screen 12 is symmetrically arranged about the central axis of the activated carbon screen 13. The filter screen 12 and the activated carbon screen 13 are fixedly connected to the inner sides of the pull-out frame 11 by adhesive bonding. The exhaust gas can be purified by the filter screen 12 and the activated carbon screen 13. A dirt collection groove 14 is provided at the bottom of the pull-out frame 11, and a dirt cleaning component 15 is installed on the pull-out frame 11. Air outlets 19 are evenly opened above the surface of the pull-out frame 11. The dirt cleaning component 15 includes an inner groove 1501, which is opened on the inner side of the pull-out frame 11. The bottom of the inner groove 1501 on the side of the pull-out frame 11 is installed with... A servo motor 1502 is provided, and a rotating lead screw 1503 is fixed to the output end of the servo motor 1502. A movable plate 1504, which is side-fitted inside the inner groove 1501, is threaded onto the rotating lead screw 1503. A partition 1505 is fixed to the surface of the movable plate 1504. The servo motor 1502 on the pull-out frame 11 can drive the movable plate 1504 to move threadedly through the rotating lead screw 1503, so that the movable plate 1504 can drive the partition 1505 to move in the inner groove 1501. The slide plate 1505 is provided on both sides of the filter screen 12, and the surface of the slide plate 1505 is bonded with a cleaning brush 1506 that adheres to the surface of the filter screen 12 and the activated carbon mesh 13. This allows the cleaning brush 1506 on the surface of the slide plate 1505 to brush the surface of the filter screen 12 and the activated carbon mesh 13, so that dirt can enter the dirt collection groove 14 inside the pull-out frame 11 for collection, thereby improving the service life of the filter screen 12 and the activated carbon mesh 13.

[0027] Working principle: First, when in use, the device is connected to the air extraction port of the chemical equipment through the air extraction pipe 4. Then, by turning on the air extraction pump 3, the gas inside the chemical equipment is introduced into the air guide pipe 7 inside the processing box 2 through the exhaust pipe 6. The air guide pipe 7 is spirally arranged, which facilitates the use of the fan 18 on the semiconductor cooling chip 16 and the built-in board 17 to cool the introduced gas. The cooled gas can then enter the pull-out frame 11, where it can pass through the filter screen 12 and activated carbon screen 13 to purify the discharged gas. Finally, the gas can be discharged from the air outlet 19 on the surface of the pull-out frame 11.

[0028] In use, the servo motor 1502 on the cleaning assembly 15 on the pull-out frame 11 can be opened, causing the servo motor 1502 to rotate the lead screw 1503 and drive the movable plate 1504 to move threadedly. This allows the movable plate 1504 to drive the partition 1505 on its surface to slide between the filter screen 12 and the activated carbon screen 13. This facilitates the cleaning brush 1506 on the surface of the partition 1505 to brush the surfaces of the filter screen 12 and the activated carbon screen 13, allowing the dirt that falls off the brush to fall into the collection tank 14 for collection, facilitating subsequent discharge and improving the service life of the filter screen 12 and the activated carbon screen 13. This is the operating principle of the air extraction device for chemical machinery.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
