Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a fully stainless steel dryer for the chemical industry. Background Technique

[0002] A dryer is a device that uses the principle of air flow to evaporate the moisture adsorbed on the surface of materials. It belongs to a kind of material processing device and is mainly used for process operations such as drying, adsorption, and dehydration. By forming a tiny drying layer on the surface of the material and using the air suction principle, moisture or other evaporates are evaporated from the surface to achieve the purpose of drying the material. It is widely used in industries such as medicine, food, and chemical industry. Among them, the adsorption dryer is a type of dryer. Its principle is to use the difference in the volume of water molecules and air molecules in saturated compressed air, and adopt a special molecular sieve for gas purification to filter out the saturated water vapor in the compressed air. The water molecules can be easily adsorbed inside the molecular sieve particles, and then the molecular sieve is restored by a regeneration method, and the dew point of the compressed air can easily reach -40°C.

[0003] However, nowadays, during the use of dryers in the chemical industry, since the chemical gas contains corrosive gases, these gases are likely to corrode the walls of the dryer components that come into contact with the chemical gas after entering the dryer, resulting in component damage and reducing the service life of the dryer.

Detailed implementation manners

[0022] As Figures 1-6 shown, a fully stainless steel dryer for the chemical industry proposed by the present utility model includes a mounting bracket 1, a dryer 2, a filter cylinder 5, a placement cylinder 24 and activated carbon 26.

[0023] As Figures 1-6As shown in the figure, a dryer 2 is installed on the mounting bracket 1. An air inlet pipe 3 and an air outlet pipe 4 are provided on the dryer 2. A filter cartridge 5 is provided on the mounting bracket 1. The filter cartridge 5 is composed of an upper shell cover 8, a middle frame 9 and a lower shell cover 10. Two lifting members are provided on the mounting bracket 1. Both lifting members are connected to the upper shell cover 8. The lifting member is composed of an electric push rod 17 and a connecting block. The electric push rod 17 is installed on the mounting bracket 1. The connecting block is installed on the upper shell cover 8. The connecting block is connected to the telescopic shaft of the electric push rod 17. A rotating assembly is provided on the mounting bracket 1. The rotating assembly includes a rotating motor 16 installed on the mounting bracket 1. A rotating rod 12 is installed on the output shaft of the rotating motor 16. A limiting member 15 is installed on the rotating rod 12. The limiting member 15 is composed of a sleeve and four vertical blocks. The four vertical blocks are annularly installed on the outer wall of the sleeve. The sleeve is sleeved on the rotating rod 12. A connecting frame 11 is slidably installed on the limiting member 15. The connecting frame 11 is connected to the middle frame 9. A limiting block 13 is installed at the bottom end of the rotating rod 12. A push spring 14 is sleeved on the rotating rod 12. Through the setting of the push spring 14, after the upper shell cover 8 rises, the middle frame 9 can be pushed to rise, so as to facilitate the removal of the sealing ring at the bottom of the middle frame 9 from the corresponding annular sealing groove. The middle frame 9 and the mounting bracket 1 can be connected through the rotating assembly. The lower shell cover 10 is connected to the mounting bracket 1. Annular sealing grooves are provided on the sides of the upper shell cover 8 and the lower shell cover 10 that are close to each other. Sealing rings are installed on both sides of the middle frame 9. The sealing rings are adapted to the sealing grooves. A connecting pipe one 6 and a connecting pipe two 7 are installed on the filter cartridge 5. The connecting pipe one 6 is connected to the air inlet pipe 3. A placing cylinder 24 is provided in the filter cartridge 5. The bottom of the placing cylinder 24 is provided with a filter screen 25 to facilitate the passage of gas through the placing cylinder 24. Activated carbon 26 is filled in the placing cylinder 24. The porous structure and high specific surface area of the activated carbon 26 can physically adsorb corrosive gases, thereby removing harmful substances in the gas.

[0024] As Figures 4-6 shown, a support ring 20 is installed on the middle frame 9. The placing cylinder 24 is arranged on the support ring 20. A plurality of magnetic grooves are provided at the top of the support ring 20. A plurality of magnetic blocks are installed at the bottom of the placing cylinder 24. The bottom of the magnetic block extends into the magnetic groove and is adapted to the magnetic groove. A heat insulation frame 21 is sleeved on the placing cylinder 24. A heating plate 22 is provided on the heat insulation frame 21. A heat conducting plate 23 is provided on the heat insulation frame 21.

[0025] As Figure 2 shown, a solenoid valve one is provided on the connecting pipe one 6. A solenoid valve two is provided on the connecting pipe two 7. A second guide pipe 19 is provided on the connecting pipe one 6. A solenoid valve three is provided on the second guide pipe 19. A first guide pipe 18 is provided on the connecting pipe two 7. A solenoid valve four is provided on the first guide pipe 18.

[0026] In this embodiment, during use, solenoid valve three and solenoid valve four are closed, and solenoid valve one and solenoid valve two are opened. Before the industrial gas enters the dryer 2, it will enter the filter cylinder 5 through the connecting pipe two 7. At this time, the corrosive substances in the industrial gas are absorbed and filtered by the filled activated carbon 26, so as to prevent the corrosive gas from entering the dryer 2 and causing corrosion damage to its workpiece components;

[0027] During daily maintenance, solenoid valve one and solenoid valve two are closed, and solenoid valve three and solenoid valve four are opened. Then, by heating the heating plate 22 and delivering the heat to the activated carbon 26 through the heat conduction plate 23, the activated carbon 26 is heat-treated to remove volatile substances such as moisture, and at the same time, the organic matter is vaporized and desorbed. Subsequently, gas such as carbon dioxide, carbon monoxide, and water vapor can be delivered into the filter cylinder 5 through the air duct one 18. The gas passes through the activated carbon 26 and is discharged through the air duct two 19 to clean the internal micropores of the activated carbon 26, so as to restore the adsorption activity of the activated carbon 26. After the number of times of restoring the adsorption activity of the activated carbon 26 by this method reaches a certain amount, the activated carbon 26 needs to be replaced. At this time, the electric push rod 17 can be started to drive the upper shell cover 8 to rise. Then, the rotating motor 16 drives the rotating rod 12 to rotate, and the connecting frame 11 drives the middle frame 9 to rotate by 90 degrees. Subsequently, the placing cylinder 24 can be taken out from the middle frame 9 for replacement. After restoring the middle frame 9 and the upper shell cover 8 to their original positions, the replacement of the activated carbon 26 can be completed, and the operation is simple and convenient.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge of those skilled in the art to which the present invention pertains.
