Description

Technical Field

[0001] The present application relates to the technical field of activated carbon production, and specifically discloses a cooling device for activated carbon production. Background Art

[0002] Activated carbon is a common amorphous carbon used for adsorption and filtration. It has been widely used in chemical industry, environmental protection, food processing, metallurgy, drug refining, military chemical protection and other fields. However, when activated carbon is used for too long, its adsorption performance will weaken and it will not achieve the ideal purification effect. If the activated carbon is directly replaced after it fails, the cost of use will be too high.

[0003] The existing technology generally regenerates the expired activated carbon and continues to use it. There are many methods for regenerating activated carbon. The thermal regeneration method is more mature and widely used. The production of activated carbon by the thermal regeneration method includes drying, carbonization, activation, cooling and other steps. The activation operation is to put the carbonized activated carbon into an activation furnace and use high-temperature steam for activation treatment. The cooling operation is to use cooling water to exchange heat with the activated carbon after activation, thereby reducing the temperature of the activated carbon out of the furnace to prevent oxidation of the activated carbon.

[0004] The existing activated carbon cooling equipment puts the activated carbon into the cooling pipe after it is activated, so that it exchanges heat with the cooling water on the outside of the cooling pipe, thereby absorbing the heat inside the activated carbon in the cooling pipe to cool the activated carbon. However, when the activated carbon is put into the cooling pipe, the activated carbon is easily accumulated at the pipe mouth, which makes it impossible for the activated carbon to slide smoothly along the pipe, affecting the cooling and furnace discharge efficiency of the activated carbon, and easily affecting the performance of the activated carbon itself. Therefore, in view of this, the inventor provides a cooling device for activated carbon production to solve the above problems. Utility Model Content

[0007] Furthermore, the pipe chain conveying mechanism includes a motor detachably mounted on the outside of the cooling circuit, an active feed sprocket rotatably connected between the inner walls of one end of the return box channel close to the feed pipe, a driven feed sprocket rotatably connected between the inner walls of one end of the discharge box channel close to the feed pipe, a discharge sprocket rotatably connected between the inner walls of one end of the discharge box channel close to the discharge port, a return sprocket rotatably connected between the inner walls of one end of the return box channel close to the return pipe, and a conveying chain meshingly connected between the active feed sprocket, the feed sprocket, the discharge sprocket and the return sprocket, the discharge sprocket is coaxially connected to the output end of the motor, and the conveying chain is evenly provided with chain plates for pushing the activated carbon to move in the feed pipe, and the chain plates can pass through the interior of the cooling circuit.

[0008] Furthermore, the transition cooling component includes a cooling fan and a mounting seat, and a transmission mechanism for driving the cooling fan to rotate is provided between the motor and the cooling fan.

[0009] Furthermore, the transmission mechanism includes a driving pulley coaxially connected to the motor, a driven pulley rotatably connected to the outer side of the return pipe, a synchronous belt cooperatively connected between the driving pulley and the driven pulley, and also includes a driving bevel gear coaxially connected to the driven pulley, a driven bevel gear meshingly connected to the driving bevel gear, a driving sprocket coaxially connected to the driven bevel gear, a driven sprocket coaxially connected to the cooling fan, and a transmission chain meshingly connected between the driving sprocket and the driven sprocket.

[0010] Furthermore, the water outlet end of the cooling water pipe passes through the activated carbon activation furnace and is connected to the water tank.

[0011] The principle and effect of this scheme are:

[0013] 2. Compared with the prior art, the utility model provides a cooling water pipe which is spirally installed on the outside of the feed pipe, and at the same time installs the cooling water pipe through the activation furnace, which not only realizes the heat exchange cooling of the activated carbon transported inside the feed pipe, but also can reuse the heat energy obtained by the heat exchange, which is energy-saving and environmentally friendly, and makes rational use of resources.

By providing a transmission mechanism to drive the rotation of the cooling fan 16, the blowing action on the end of the discharge port 6 is achieved, which is convenient for further cooling of the activated carbon in the process of the activated carbon entering the receiving box 9 from the discharge port 6, so that the activated carbon avoids direct contact with the temperature difference between the internal environment and the external environment of the cooling circuit, which is beneficial to the protection of the structure of the activated carbon.
