Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon drying equipment, in particular to a drying treatment device for preparing activated carbon. Background Art

[0002] Activated carbon is a porous, high-surface-area carbonaceous material that is widely used in a variety of fields such as adsorption, filtration, and catalysis. In the production process of activated carbon, drying is a crucial step, which directly affects the pore structure, specific surface area, and adsorption performance of activated carbon. Traditional activated carbon drying devices usually only focus on improving drying efficiency and reducing energy consumption, but often do not pay enough attention to the filtration and purification of hot air during the drying process. In the drying process of activated carbon, hot air or hot steam is used as a drying medium to evaporate the water in the activated carbon through heat exchange, thereby achieving the purpose of drying. However, before entering the drying chamber, these hot gases often carry various impurities, such as dust, particulate matter, and microorganisms. If these impurities enter the drying chamber directly, they will come into contact with the activated carbon and may be deposited in the pores of the activated carbon, causing pore blockage and affecting the adsorption performance of the activated carbon. Therefore, we propose a filterable activated carbon drying device.

[0005] Therefore, it is necessary to design a drying treatment device for preparing activated carbon that is practical and filterable. Utility Model Content

The interior of the four side panels of the drying box 1 is hollow and connected, and is also connected to the air inlet 12 and the air outlet 13, so that the hot air used for drying can enter the interior of the drying box 1 from the side panel to dry and heat the interior, and at the same time, the hot air can also be inside the four side panels to heat the side panels, so that the side panels can heat the activated carbon attached to the side panels. When the preparation work is done, the staff will send the hot air in through the air inlet 12, and the hot air will pass through the circular groove 15. The circular groove 15 is provided with a filter screen. There may be some impurities in the heated gas, which can be blocked by the filter screen outside, and the continuously filtered impurities will be attached to the filter screen. Therefore, when working, the staff can turn on the double-headed motor 2, so that the rotating shaft 21 will rotate, and the scraping mechanism will bring the scraping block 26 to scrape the surface of the filter screen inside the circular groove 15, and at the same time, the rotating rod 3 will also rotate, and the rotating mechanism will bring the internal activated carbon to stir repeatedly. The device is provided with a scraping mechanism to scrape impurities on the surface of the filter, keep the filter clean and the filtering effect, and avoid the problem of filter clogging affecting the filtering efficiency. The device is provided with a rotating mechanism to evenly stir the internal activated carbon.

The device only uses a double-headed motor 2, which drives the scraping and rotating movements at the same time, saving the device and saving costs.

[0028] The scraping mechanism includes a first gear 22, the first gear 22 is fixedly connected to the rotating shaft 21, the two sides of the first gear 22 are meshed with the second gear 23, the second gear 23 is rotatably connected to the inner side of the drying box 1, one side of the second gear 23 is fixedly connected to the third gear 24, the middle parts of the two third gears 24 are meshed with a double rack 25, the double rack 25 is slidably connected to the inner side of the drying box 1, and the double rack 25 is fixedly connected to the scraping block 26; when the staff turns on the double-headed motor 2, the rotating shaft 21 rotates, bringing the first gear 22 rotates, so that the two second gears 23 rotate, and the directions of rotation of the two second gears 23 are the same, so that the two third gears 24 will also rotate, and the upper third gear 24 rotates clockwise, meshes with the double rack 25, and pushes the double rack 25 to the left. When the upper third gear 24 and the double rack 25 are not meshed, the lower third gear 24 meshes with the double rack 25, and pushes the double rack 25 to the right, so that the left and right reciprocating movement of the double rack 25 is achieved, so that the scraper block 26 can scrape the surface of the filter screen in the circular groove 15.

[0029] The two third gears 24 are incomplete gears; the third gear 24 has only about half of the teeth, so that the two third gears 24 can be meshed in sequence.

[0030] The two third gears 24 are in the same direction, and the two third gears 24 and the double rack 25 are meshed in sequence; when the two third gears 24 rotate, the directions are always consistent. When the meshing of one third gear 24 and the double rack 25 ends, the other third gear 24 and the double rack 25 are just meshed.

[0031] The rotating mechanism includes a spiral block 31 and a short rod 32, both of which are fixedly connected to the rotating rod 3, and the short rods 32 are equidistant from each other; the spiral block 31 stirs the activated carbon evenly, and the short rod 32 enhances the stirring effect and increases the stirring range.
