Description

Technical Field

[0002] High-temperature and high-pressure gas filtering devices are used to filter high-pressure gases. Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, and urban water supply. Existing filtering devices often use a variety of filter screens to filter gases, but when the filter screen is used for too long, it is easy to cause blockage, thereby reducing the filtering effect on the gas, so that the staff needs to manually replace the filter screen, but it will increase the use of manpower.

By setting the non-woven fabric layer and the activated carbon layer, the non-woven fabric layer adsorbs impurities mixed therein while ensuring the permeability of the high-temperature and high-pressure gas, and the activated carbon layer removes various toxic and harmful gases such as odor, stink, carbon monoxide, etc. in the high-temperature and high-pressure gas. However, this setting uses a cloth layer and an activated carbon layer to filter the gas, but when the filtering time is too long, workers need to replace it, thereby increasing the use of manpower. Therefore, in view of this problem, how to design a high-temperature and high-pressure gas filtering circulation device has become a problem that we currently need to solve. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a high-temperature and high-pressure gas filtering and circulating device according to an embodiment of the utility model comprises a main body 1, a flow guide pipe 2 is connected to the top of the main body 1, a first circulation pipe 3 is connected to one end of the flow guide pipe 2, the first circulation pipe 3 is connected to the main body 1, a water tank 4 is fixedly installed on the outside of the first circulation pipe 3, and the gas in the first circulation pipe 3 is cooled by the arrangement of the water tank 4. Figure 2 As shown, the top of the water tank 4 is connected to a first air duct 5, the interior of the first air duct 5 is rotatably connected to a first rotating shaft 6, and a fan blade 7 is fixedly installed on the outer side of the first rotating shaft 6. The number of the fan blades 7 is set to be multiple, wherein every two fan blades 7 are axially symmetrically arranged about the vertical center line of the water tank 4, as shown in FIG. Figure 3 As shown, the first circulation pipe 3 is internally slidably connected with a combined filter screen 8, and the gas is subjected to multiple filtrations through the setting of the combined filter screen 8. A protrusion 9 is fixedly installed on the top of the combined filter screen 8, and an L-shaped transmission rod 10 is fixedly installed on the bottom of the first rotating shaft 6. A slide groove 11 is slidably connected to the outer side of the L-shaped transmission rod 10, and a fixed rod 13 is fixedly installed on one side of the slide groove 11. The fixed rod 13 is slidably connected to one side of the main body 1.

[0022] It should be noted that, when the gas in the main body 1 enters the first circulation pipe 3 through the flow guide pipe 2, part of the gas will enter the second circulation pipe 27 and enter the flow guide pipe 2 again. The gas entering the flow guide pipe 2 from the second circulation pipe 27 will impact the gas in the flow guide pipe 2, thereby reducing the pressure of the high-pressure gas in the flow guide pipe 2. Since the gas entering the first circulation pipe 3 from the flow guide pipe 2 is more than the gas flowing out of the second circulation pipe 27, it will not cause the gas in the flow guide pipe 2 to flow back. The gas entering the first circulation pipe 3 will be The first circulation pipe 3 is in contact with the water tank 4, thereby heat conversion is carried out with the water in the water tank 4, so that the temperature of the gas in the first circulation pipe 3 is absorbed by the water flow inside the water tank 4. As the temperature of the water in the water tank 4 gradually increases, and because the water tank 4 is a sealed setting, the steam in the water tank 4 gradually increases, which will push the floating air plate 18 upward, so that the floating air plate 18 drives the air plug 17 to rise. When the air plug 17 rises to the middle section of the slide cylinder 16, the first air guide pipe 5 is connected with the slide cylinder 16. At this time, the steam in the water tank 4 enters the interior of the first air guide pipe 5, so that the fan blade 7 rotates and then through the first rotating shaft 6 to make The L-shaped transmission rod 10 rotates, and when the L-shaped transmission rod 10 rotates, it slides on the inner wall of the slide groove 11, so that the slide groove 11 drives the fixed rod 13 to slide back and forth. When the fixed rod 13 slides to one side, it drives the limit plate 14 to slide on the top of the combined filter screen 8. When the limit plate 14 contacts the protrusion 9, the limit plate 14 flips upward, and when the limit plate 14 slides to one side of the protrusion 9, the limit plate 14 is reset by the stretching of the reset spring 15. At this time, the reset spring 15 slides to the farthest distance and starts to slide in the opposite direction under the rotation of the L-shaped transmission rod 10. When the steam stored in the water tank 4 is used up, the combined filter screen 8 stops sliding at the same time. At this time, the combined filter screen 8 is located in the first circulation pipe 3 and the filter screen after use is switched out of the first circulation pipe 3, so that the filter screen can be replaced regularly, thereby avoiding the phenomenon that the filtering effect is reduced due to the long use of the filter screen, and reducing the manpower required for manual replacement of the filter screen.

[0023] Further, such as Figure 3 As shown, the bottom of the fixed rod 13 is hinged with a limit plate 14, and a return spring 15 is provided on one side of the limit plate 14. The return spring 15 is fixedly installed at the bottom of the fixed rod 13. A slide cylinder 16 is fixedly installed on the inner wall of the water tank 4. The slide cylinder 16 is connected to the first air guide pipe 5. Figure 2As shown, the inner wall of the slide cylinder 16 is slidably connected with an air plug 17. Through the setting of the air plug 17, the steam in the water tank 4 can flow out only when the excess steam pushes the air plug 17 to slide. The top of the air plug 17 is fixedly installed with a floating plate 18. Through the setting of the floating plate 18, the steam in the water tank 4 is sealed, so that the steam directly contacts the floating plate 18 and the floating plate 18 rises. The floating plate 18 is slidably connected to the inner wall of the water tank 4, as shown in FIG. Figure 1 As shown, the top of the water tank 4 is connected to a second air guide pipe 20. Figure 4 As shown, the second air guide tube 20 is rotatably connected to the inside with a second rotating shaft 21, a cleaning brush 22 is fixedly installed at the bottom end of the second rotating shaft 21, a beveled top block 23 is fixedly installed on the outside of the cleaning brush 22, a water valve 24 is slidably connected to the inside of the water tank 4, a rounded block 25 is fixedly installed at the bottom end of the water valve 24, an L-shaped slide groove 26 is connected to one side of the water tank 4, and the water valve 24 is slidably connected to the inner wall of the L-shaped slide groove 26, as shown in FIG. Figure 1 As shown, the outer side of the flow guide pipe 2 is connected to a second circulation pipe 27 .

[0024] It should be noted that, when the air float plate 18 rises, the steam in the water tank 4 will simultaneously enter the interior of the second air guide pipe 20, thereby driving the corresponding fan blades 7 to rotate, and then causing the second rotating shaft 21 to rotate. When the second rotating shaft 21 rotates, it will drive the cleaning brush 22 to rotate. Since the used filter in the combined filter 8 has been moved to one side at this time and is at the bottom of the cleaning brush 22, the filter will be brushed when the cleaning brush 22 rotates. When the cleaning brush 22 rotates, it will drive the beveled top block 23 to rotate synchronously. When the beveled top block 23 contacts the rounded corner block 25, the rounded corner block 25 Under the guidance of the bevel of the beveled top block 23, it rises, so that the water valve 24 rises, and then the water tank 4 is connected with the L-shaped chute 26. At this time, the water in the water tank 4 flows into the inside of the cleaning brush 22 from the L-shaped chute 26, and flows into the bottom of the cleaning brush 22 through the water flow hole opened by the cleaning brush 22, so that the cleaning brush 22 adds water to the used filter screen in the combined filter screen 8 and brushes it, thereby cleaning the used filter screen, thereby realizing the recycling of the filter screen. The gas in the first circulation pipe 3 flows into the main body 1 again after being cooled and filtered, thereby realizing circulation.
