[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The compressed gas drying device disclosed in the present invention is mainly used in the scene where the drying effect of compressed gas is poor and the water content of the gas is high.

[0030] Reference Figure 1-8 A compressed gas drying device comprises a drying cylinder 1, a vent seat 2 is arranged at the bottom of the drying cylinder 1, and a top cylinder 3 is arranged at the top of the drying cylinder 1, the top cylinder 3 is connected to the drying cylinder 1 by bolts, an exhaust pipe 4 is connected to the upper side of the top cylinder 3 by bolts, and a filling cylinder 5 is arranged outside the top cylinder 3, the lower port of the filling cylinder 5 is communicated with the inner cavity of the drying cylinder 1, a storage bin 6 is arranged outside the filling cylinder 5, the storage bin 6 and the filling cylinder 5 are connected by bolts, an automatic control valve 7 is arranged between the storage bin 6 and the filling cylinder 5, and a feeding door 8 is arranged above the storage bin 6.

[0031] Specifically, in the drying process of compressed gas, the particles in the storage bin 6 are sprinkled into the drying cylinder 1 by the filling cylinder 5, and the compressed gas is transported into the ventilation seat 2, and then transported upward from the bottom of the drying cylinder 1 into the drying cylinder 1. The upward-flowing compressed gas will directly act on the particles in the drying cylinder 1, driving the particles to move irregularly in the drying cylinder 1. During this process, the moisture in the compressed gas will be absorbed by the particles, thereby achieving the effect of drying the gas. The device adopts a method of reciprocatingly adding water-absorbing particles in the drying cylinder 1, and uses the compressed air flowing from the bottom to the top to drive the movement of the water-absorbing particles. In the process, the contact effect between the compressed air and the water-absorbing particles can be increased, thereby achieving the purpose of drying the compressed gas.

[0032] Reference Figure 2 and Figure 3 An annular groove is provided at the bottom of the top cylinder 3, and a movable separation cylinder 9 is slidably connected inside the annular groove. The movable separation cylinder 9 is located inside the drying cylinder 1, and a filter screen 10 is provided on the movable separation cylinder 9. A plurality of circumferentially equidistant return springs 11 are connected to the upper side of the movable separation cylinder 9 by bolts, and the top ends of the plurality of return springs 11 are connected to the inner wall of the annular groove of the top cylinder 3 by bolts.

[0033] Specifically, the compressed gas after adsorption and drying in the drying cylinder 1 enters the top cylinder 3 from the movable separation cylinder 9, and is then transported to the external gas pipeline by the exhaust pipe 4. During the process of the compressed gas entering the movable separation cylinder 9, due to the light weight of the water-absorbing particles, the compressed gas will drive some of the water-absorbing particles to float up. When the compressed gas enters the movable separation cylinder 9, the filter 10 will prevent the water-absorbing particles from entering the exhaust pipe 4. At the same time, the kinetic energy of the compressed gas circulation will act on the movable separation cylinder 9. The state of the movable separation cylinder 9 changes after being subjected to force, the reset spring 11 undergoes elastic deformation, the movable separation cylinder 9 and the filter 10 float irregularly, which accelerates the falling of the water-absorbing particles and prevents the water-absorbing particles from adhering to the filter 10 and affecting its filtration and gas circulation efficiency.

Four circumferentially equidistant spacer plates 13 are connected to the plurality of built-in rings 12 by bolts, and the spacer plates 13 on two adjacent vertically equidistant built-in rings 12 are staggered with each other.

[0035] Specifically, the particles falling from the filling cylinder 5 will fall on the partition plate 13 for temporary storage, and the compressed gas flowing upward in the drying cylinder 1 will form a backflow on the partition plate 13, thereby forming an irregular gas flow state in the drying cylinder 1, thereby increasing the residence time of the compressed gas in the drying cylinder 1 and the contact effect between the compressed gas and the particles, and increasing the water absorption and drying effect of the compressed gas.

[0036] Reference Figure 4 The lower side of the drying cylinder 1 is connected to a bottom cylinder 14 by bolts, and the bottom cylinder 14 is located between the drying cylinder 1 and the ventilation seat 2. The bottom cylinder 14 is provided with a plurality of circumferentially equidistant air inlet grooves 15, and the ventilation seat 2 is provided with a ventilation cavity 16, the air inlet grooves 15 are connected with the ventilation cavity 16, and the ventilation seat 2 is connected to an external seat 17 by bolts, and the external seat 17 is provided with a plurality of equidistant external interfaces.

[0037] Specifically, the compressed gas enters the ventilation seat 2 and then flows into the ventilation cavity 16 , and then passes through the exhaust groove of the bottom cylinder 14 and enters the interior of the drying cylinder 1 upward.

[0038] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 A scraper combing assembly 19 is provided above the bottom cylinder 14; the scraper combing assembly 19 includes a gear ring 1901 and a plurality of brush plates 1902. An annular mounting groove is provided on the drying cylinder 1. The gear ring 1901 is rotatably connected in the annular mounting groove of the drying cylinder 1. The plurality of brush plates 1902 are connected to the inner wall of the gear ring 1901 by bolts. The plurality of brush plates 1902 are equidistantly distributed on the circumference. The plurality of brush plates 1902 are all located above the bottom cylinder 14. The lower sides of the plurality of brush plates 1902 are all provided with brushes 1903. The lower ends of the brushes 1903 are in contact with the bottom cylinder 14. The outside of the drying cylinder 1 is connected to a motor seat by bolts. A drive motor 1904 is connected to the motor seat by bolts. The output end of the drive motor 1904 is connected to a rotating shaft by a coupling. A driving gear 1905 is connected to the other end of the rotating shaft by bolts. The driving gear 1905 meshes with the tooth groove of the gear ring 1901.

[0039] Specifically, the driving motor 1904 drives the driving gear 1905 to engage the gear ring 1901, and the gear ring 1901 rotates to drive the brush plate 1902 to rotate inside the drying cylinder 1, and the brush 1903 on the brush plate 1902 brushes the bottom cylinder 14;

[0040] In a specific application scenario, the scraper and combing component 19 is suitable for cleaning the inner wall of the bottom cylinder 14, that is, the scraper and combing component 19 uses a rotating brush plate 1902 and a brush 1903 to continuously brush the upper side of the bottom cylinder 14, thereby assisting the particles on the upper side of the bottom cylinder 14 to slide down. At the same time, the particles adhering to the bottom cylinder 14 can be cleaned during the brushing process to prevent the particles from clogging the air inlet groove 15 and affecting the circulation of compressed gas.

[0041] Reference Figure 1 , Figure 5 and Figure 7, a material blocking and discharging assembly 18 is provided below the drying cylinder 1; the material blocking and discharging assembly 18 comprises a material dropping bin 1801 and a material discharging barrel 1802, the middle part of the ventilation seat 2 is arranged in an annular shape, the material dropping bin 1801 is located in the middle part of the ventilation seat 2, the upper end of the material dropping bin 1801 is connected to the lower end of the bottom cylinder 14 by bolts, the cross section of the material dropping bin 1801 is funnel-shaped, a material blocking plate 1803 is provided inside the material dropping bin 1801, the material blocking plate 1803 is in the shape of an inverted bowl, a plurality of circumferentially equidistant vertical rods 1804 are connected to the lower side of the material blocking plate 1803 by bolts, the lower end of the vertical rod 1804 is connected to the inner wall of the material dropping bin 1801 by bolts, and the material discharging barrel 1802 is located below the material dropping bin 1801, and a material discharge port 180 is provided on the upper side of the material discharging barrel 1802 5. The lower end of the discharge bin 1801 is connected to the discharge port 1805 by bolts, and a discharge pipe 1806 is provided at the lower end of the discharge barrel 1802. The discharge pipe 1806 and the discharge port 1805 are located at different ends of the discharge barrel 1802. The end of the discharge barrel 1802 close to the discharge pipe 1806 is connected to a feeding motor 1809 by bolts, and the output end of the feeding motor 1809 is connected to a shaft rod 1808 through a coupling. A circular hole is provided at the end of the discharge barrel 1802 close to the discharge pipe 1806, and the other end of the shaft rod 1808 passes through the circular hole and is rotatably connected to the inner wall of the discharge barrel 1802 through a bearing. The outside of the shaft rod 1808 is connected to a spiral conveying blade 1807 by bolts, and the spiral conveying blade 1807 is located inside the discharge barrel 1802.

[0042] Specifically, the weight of the particles in the drying cylinder 1 will increase after absorbing water. The compressed gas entering the drying cylinder 1 cannot support the suspension of the particles, and the particles fall down and slide from the bottom cylinder 14 into the discharge cylinder 1802. The feeding motor 1809 keeps rotating to drive the shaft 1808 to rotate, and the spiral conveying blades 1807 continuously convey the particles entering the discharge cylinder 1802 to the outside, and finally fall down and are collected at the discharge pipe 1806.

[0043] In a specific application scenario, the material blocking and discharge component 18 is suitable for the discharge of particles in the drying cylinder 1 after absorbing water, that is, the material blocking and discharge component 18 uses the rotating spiral conveying blades 1807 to continuously convey the particles that have increased in weight and fallen after absorbing water to the discharge device, thereby preventing the particles from falling at the bottom after absorbing water and causing accumulation, thereby reducing the suspension effect of the particles in the drying cylinder 1, and at the same time, the transported and discharged particles can be added to the storage bin 6 again after drying for recycling; the material blocking plate 1803 is in the shape of an inverted bowl, which can effectively separate the space between the inner cavity of the drying cylinder 1 and the discharge cylinder 1802, thereby preventing the compressed air in the drying cylinder 1 from flowing back into the discharge cylinder 1802.

[0044] Reference Figure 1 and Figure 8, a pretreatment component 20 is arranged outside the drying cylinder 1; the pretreatment component 20 includes a cooling cylinder 2001 and a drying box 2002, a plurality of adsorption layers 2004 are arranged inside the drying box 2002, a plurality of equidistant ports are arranged at the upper end of the drying box 2002, the interiors of the plurality of ports are connected with connecting pipes 2003 by bolts, the other ends of the plurality of connecting pipes 2003 are connected with a plurality of external interfaces on the external connection seat 17 by bolts, a plurality of pipes are connected to the lower side of the drying box 2002 by bolts, and a plurality of adsorption layers 2004 are arranged inside the cooling cylinder 2001, There are multiple equally spaced curved flow tubes 2005, one end of which is connected to multiple pipes by bolts, and the other ends of which are connected to air inlet pipes 2006 by bolts. The air inlet pipes 2006 are all located outside the cooling cylinder 2001. The cooling cylinder 2001 is provided with a liquid inlet seat 2007 and a liquid drain seat 2008. The liquid inlet seat 2007 is located on a side of the cooling cylinder 2001 close to the drying box 2002, and the liquid drain seat 2008 is located on a side of the cooling cylinder 2001 close to the air inlet pipe 2006.

[0045] Specifically, after being heated and dried, the compressed gas enters the curved flow pipe 2005 through the air inlet pipe 2006. During the circulation in the curved flow pipe 2005, the coolant in the cooling cylinder 2001 will indirectly cool the compressed gas in the curved flow pipe 2005, so that the water decomposed by heating is condensed and precipitated, and then adsorbed by the adsorption layer 2004 in the drying box 2002.

[0046] In a specific application scenario, the pretreatment component 20 is suitable for the pretreatment link before the compressed gas enters the drying cylinder 1, that is, the pretreatment component 20 uses condensate to cool the compressed gas from the outside of the curved flow tube 2005, thereby increasing the precipitation of moisture in the compressed gas, facilitating the adsorption of the adsorption layer 2004, reducing the overall moisture content of the compressed gas when it enters the drying cylinder 1, and improving the overall drying effect of the compressed gas; using the curved flow tube 2005 can increase the circulation time of the gas in the pipeline, thereby improving the cooling effect on the gas in the pipeline.

[0047] Working principle: When in use, in the drying process of compressed gas, the particles in the storage bin 6 are sprinkled into the drying cylinder 1 through the filling cylinder 5, and the compressed gas is transported into the ventilation seat 2 (the compressed gas enters the curved flow pipe 2005 through the air inlet pipe 2006 after being heated and dried. During the circulation in the curved flow pipe 2005, the coolant in the cooling cylinder 2001 will indirectly cool the compressed gas in the curved flow pipe 2005, so that the water decomposed by heating is condensed and precipitated, and then adsorbed by the adsorption layer 2004 in the drying box 2002), and then transported upward from the bottom of the drying cylinder 1 into the drying cylinder 1. The compressed gas flowing upward will directly act on the particles in the drying cylinder 1, driving the particles to move irregularly in the drying cylinder 1. In this process, the water in the compressed gas will be absorbed by the particles, achieving the effect of drying the gas;

[0048] The particles falling from the filling cylinder 5 will fall on the partition plate 13 for temporary storage, and the compressed gas flowing upward in the drying cylinder 1 will form a backflow on the partition plate 13, thereby forming an irregular gas flow state in the drying cylinder 1, which increases the residence time of the compressed gas in the drying cylinder 1 and the contact effect between the compressed gas and the particles. The weight of the particles in the drying cylinder 1 will increase after absorbing water. The compressed gas entering the drying cylinder 1 cannot support the suspension of the particles, and the particles fall and slide from the bottom cylinder 14 into the discharge cylinder 1802. The feeding motor 1809 is always rotating to drive the shaft 1808 to rotate, and the spiral conveying blades 1807 will continuously convey the particles entering the discharge cylinder 1802 to the outside, and finally fall and collect at the discharge pipe 1806.
