Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon production, in particular to an activated carbon drying and shaping device. Background Art

[0002] The strip-shaped activated carbon after extrusion and cutting contains a high amount of moisture, and needs to be dried or dried to remove the moisture while ensuring that the activated carbon maintains a good strip appearance.

[0003] The traditional method is to dry the activated carbon in the sun or in a static state. This method cannot effectively flip the activated carbon material, making it difficult to dry the bottom material. If mechanical stirring is used, the material shape will be damaged or even broken into slag. In addition, if the drying temperature is low, the drying process will be slow and inefficient. If the drying temperature is high, the surface of the activated carbon material will lose water quickly, causing deformation and cracking.

[0004] Therefore, there is an urgent need for an activated carbon drying and shaping device that can improve the material drying efficiency without destroying the structure of the activated carbon material. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an activated carbon drying and shaping device, which realizes a multi-stage drying process for the activated carbon from low temperature to medium temperature and then to high temperature, dynamically dries the activated carbon during transportation, and turns the material over when transferring the material, so as to improve the drying efficiency of the activated carbon and prevent problems such as structural damage, deformation and cracking of the formed activated carbon material.

[0006] The utility model provides an activated carbon drying and shaping device, including a multi-stage drying system, a cooling system and a heating system, wherein:

[0007] The multi-stage drying system comprises a drying box, a wet material feed port is arranged on one side of the upper part of the drying box, a dry material discharge port is arranged on the bottom, a hot air inlet is arranged on one side of the lower part of the drying box, a cold air outlet is arranged on the top, a plurality of partitions are arranged transversely in the drying box, the partitions divide the drying box into a plurality of drying chambers, a group of drying conveyor belts are arranged in each drying chamber, and an air delivery port and a material discharge port are arranged on each partition;

[0008] The cooling system comprises a cooling box, the top of the cooling box is connected to the drying box through a dry material discharge port, the side of the cooling box is provided with a cold material discharge port and a cold air inlet, a cooling conveyor belt is arranged in the cooling box, one end of the cooling conveyor belt is located below the dry material discharge port, and the other end thereof is arranged at the cold material discharge port;

[0009] The heating system comprises a heating furnace, in which a heating coil is arranged, an air inlet end of the heating coil is communicated with a cooling box, and an air outlet end thereof is communicated with a hot air inlet.

[0010] Preferably, two partitions are provided in the drying box body, dividing the drying box body into three drying chambers, and the drying chambers include a primary drying chamber, a secondary drying chamber and a tertiary drying chamber which are sequentially connected from top to bottom.

[0011] Preferably, the hot air inlet is arranged on one side of the first-stage drying chamber, the air outlet end of the heating coil is connected to an air outlet branch pipe, the air outlet branch pipe is connected to the second-stage drying chamber and the third-stage drying chamber respectively, and a solenoid valve is provided on the air outlet branch pipe.

[0012] Preferably, it also includes a condensate diversion system, which includes a guide plate obliquely arranged on the top of the drying box, a guide groove is arranged below the lower side of the guide plate, a guide hole is arranged on the side wall of the drying box located in the guide groove, and a guide pipe is connected to the bottom of the guide groove.

[0013] Preferably, guide plates are obliquely arranged at the feed outlet and the dry material discharge outlet.

[0014] Preferably, fan blades are respectively provided at the air supply port and the hot air inlet.

[0015] Preferably, a negative pressure fan is provided on the cold air outlet, and an air supply fan is provided on the heating coil.

[0016] Preferably, the drying conveyor belt and the cooling conveyor belt are respectively arranged to be inclined, and the inclination angle is 5 to 30 degrees.

[0017] Working principle of the utility model: When the activated carbon drying and shaping device of the utility model is used, the strip activated carbon after extrusion molding and cutting in the previous process falls to the drying conveyor belt in the first drying chamber at the wet material feed port, and after low-temperature drying, falls to the drying conveyor belt in the second drying chamber from the feed port, and after medium-temperature drying, falls to the drying conveyor belt in the third drying chamber from the feed port, and after high-temperature drying, falls to the cooling conveyor belt in the cooling box from the dry material discharge port, and is cooled and sent out from the cold material discharge port.

Secondly, the multi-stage drying process from low temperature to medium temperature and then to high temperature can prevent the activated carbon material from losing water rapidly due to high-temperature drying, resulting in deformation and surface cracking. In addition, the device uses the cooling gas as a drying medium after being heated in the heating furnace, which can effectively utilize the waste heat from the cooling of the activated carbon material. At the same time, the high-temperature section gas is sequentially sent to the medium-temperature and low-temperature sections, and the heat in the cooling hot gas is fully utilized, thereby achieving the purpose of saving energy.
