Description

Technical Field

[0001] This utility model relates to the field of roller kiln technology, and in particular to a roller kiln with good drying effect. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials are heated in the absence of air to reduce non-carbon components, and then react with gases. The surface is eroded, creating a structure with well-developed micropores. Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, which results in countless tiny pores on the surface of activated carbon. Activated carbon needs to be dried during production.

[0003] In existing technologies, activated carbon products need to be dried during production. Some drying equipment uses direct hot air blowing, which leads to uneven heating temperature distribution and uneven drying of activated carbon, making it prone to pulverization and disintegration. Therefore, a roller kiln with good drying effect is needed to meet people's needs. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6A roller kiln with good drying effect includes a roller kiln channel 100. Mounting frames 101 are fixedly installed at both ends of the roller kiln channel 100. Conveyor rollers 102 are rotatably mounted on the mounting frames 101, and activated carbon 103 is arranged on the conveyor rollers 102. Side mounting frames 104 are fixedly installed on the inner walls of both sides of the roller kiln channel 100. An internal conveyor roller 105 is rotatably mounted between the two side mounting frames 104. A control box 200 is arranged on one side of the roller kiln channel 100. Two partitions 300 and heat-resistant silicone baffles 301 are arranged inside the roller kiln channel 100. The partition 300 and the heat-resistant silicone baffle 301 divide the roller kiln channel 100 into a preheating chamber 302, a drying chamber 303, and a cooling chamber 304. The preheating chamber, drying chamber, and cooling chamber are used to process activated carbon inside the roller kiln channel. At the same time, the top drying nozzles and bottom drying nozzles are arranged alternately to blow hot air directly onto the activated carbon in the vertical direction to achieve uniform heating and drying. Meanwhile, the hot air in the drying chamber is transported to the preheating chamber by a turbine fan, and the waste heat of the hot air is used to preheat the activated carbon, making full use of thermal resources and reducing costs.

[0023] A hot air pipe 400 is fixedly installed at the top of the roller kiln channel 100. An internal hot air pipe 401 is fixedly installed at one end of the hot air pipe 400 that extends into the roller kiln channel 100. A top drying air duct 402 is fixedly installed on the inner wall of the top side of the drying chamber 303. A top drying nozzle 403 is fixedly installed on the top drying air duct 402. A bottom drying air duct 404 is fixedly installed on the inner wall of the bottom side of the drying chamber 303. Several bottom drying nozzles 405 are fixedly installed on the bottom drying air duct 404. Both the bottom drying air duct 404 and the top drying air duct 402 are connected to the internal hot air pipe 401. Hot air is injected into the internal drying chamber 303 through the hot air pipe 400 and the internal hot air duct 401. The air is delivered to the top of the activated carbon 103 by the top drying air duct 402 and the top drying nozzle 403, while the bottom drying air duct 404 and the bottom drying nozzle 405 blow air to the bottom of the activated carbon 103. The top drying nozzle 403 and the bottom drying nozzle 405 blow air alternately above and below the activated carbon 103 to achieve sufficient heating of the activated carbon 103.

[0024] The top inner wall of the preheating chamber 302 is fixedly installed with a top preheating air duct 406, and a number of top preheating nozzles 407 are fixedly installed on the bottom side of the top preheating air duct 406. The bottom side of the preheating chamber 302 is fixedly installed with a bottom preheating air duct 408, and a number of bottom preheating nozzles 409 are fixedly installed on the bottom preheating air duct 408.

[0025] A collection pipe 500 and a turbine fan 501 are fixedly installed on the side of the roller kiln channel 100. A recovery pipe 502 is fixedly installed between the input end of the turbine fan 501 and the collection pipe 500, and a conveying pipe 503 is fixedly installed at the output end of the turbine fan 501. The conveying pipe 503 is connected to the top preheating air duct 406 and the bottom preheating air duct 408. To avoid wasting hot air, the turbine fan 501 conveys the hot air from the preheating chamber 302 into the preheating chamber 302 through the recovery pipe 502 and the collection pipe 500 via the conveying pipe 503.

[0026] A cooling fan 600 is fixedly installed at the top of the roller kiln channel 100. Exhaust holes 601 are provided on both sides of the roller kiln channel 100, and filters 602 are fixedly installed inside each exhaust hole 601. The cooling fan 600 is used for heat dissipation, and the airflow of the cooling fan 600 is gradually increased to stably reduce the heat wave of the activated carbon 103, facilitating normal handling of the activated carbon 103 after it exits the roller kiln channel 100.

[0027] The top drying nozzle 403 and the bottom drying nozzle 405 are arranged alternately on the top and bottom sides of the preheating chamber 302, and the top preheating nozzle 407 and the bottom preheating nozzle 409 are also arranged alternately on the top and bottom sides of the preheating chamber 302. Air is vented above the activated carbon 103 using the top preheating duct 406 and the top preheating nozzle 407, and air is blown below the activated carbon 103 using the bottom preheating duct 408 and the bottom preheating nozzle 409. This preheating process effectively utilizes thermal resources and reduces resource waste.

[0028] Working principle:

[0029] When using this device, activated carbon 103 needs to be conveyed into the roller kiln channel 100 via conveyor roller 102 and internal conveyor roller 105. Hot air is injected into the internal drying chamber 303 through hot air pipe 400 and internal hot air pipe 401. Air is blown above the activated carbon 103 using top drying air duct 402 and top drying nozzle 403, while air is blown below the activated carbon 103 using bottom drying air duct 404 and bottom drying nozzle 405. The top drying nozzle 403 and bottom drying nozzle 405 alternately blow air above and below the activated carbon 103 to achieve sufficient heating of the activated carbon 103. To avoid hot air waste, a turbine fan 501 is used to collect the heat from the preheating chamber 302 through recovery pipe 502 and collection pipe 500. Air is delivered to the preheating chamber 302 through the conveying pipe 503. Air is vented above the activated carbon 103 using the top preheating air duct 406 and the top preheating nozzle 407, and air is blown under the activated carbon 103 using the bottom preheating air duct 408 and the bottom preheating nozzle 409. This preheating process fully utilizes thermal resources and reduces waste. After the activated carbon 103 is dried, it is cooled by the cooling fan 600. The cooling fan 600 gradually increases its air volume to stabilize and reduce the heat wave of the activated carbon 103, making it easy for workers to handle the activated carbon 103 after it comes out of the roller kiln channel 100. The partition 300 and the heat-resistant silicone baffle 301 are used for separation.
