DETAILED DESCRIPTION

[0023] See also Figure 1-9 The utility model provides the following technical solutions: an activated carbon carbonization furnace with rapid heating, comprising a shell 1, an exhaust groove 2, an electric stirring rod 3, a slide rail 5, a steam generator 6 and a fan 7, and also comprising a cooling mechanism 4 and a material dividing block 8. The interior of the shell 1 is divided into three spaces by a partition. The interior space of the shell 1 is a preheating bin 11, a carbonization bin 12 and an activation bin 13 from top to bottom. The side wall of the shell 1 is provided with an exhaust groove 2 which is connected to the preheating bin 11, the carbonization bin 12 and the activation bin 13 respectively. Two electric stirring rods 3 are respectively installed on the preheating bin 11 and the carbonization bin 12. The partition of the shell 1 A plurality of through grooves with sealing valves 81 are evenly opened on the bottom surface, a dividing block 8 is installed on the top of the through groove of the partition of the outer shell 1, a plurality of storage pipes 15 cooperating with the through groove are arranged on the activation bin 13, a heating pipe 71 respectively connected with the preheating bin 11, the carbonization bin 12 and the activation bin 13 is arranged on the fan 7, the heating pipe 71 connected with the activation bin 13 is connected with the steam generator 6, a plurality of ventilation baffles 72 connected with the heating pipe 71 are arranged on the inner walls of the preheating bin 11 and the carbonization bin 12, the blades of the electric stirring rod 3 are located between the ventilation baffles 72, and a cooling mechanism 4 is arranged at the bottom of the outer shell 1.

[0024] The preheating bin 11 is used for preheating raw materials, the carbonization bin 12 is used for carbonizing raw materials, and the activation bin 13 is used for activating activated carbon. The preheating bin 11, the carbonization bin 12 and the activation bin 13 are separated by the cooperation of the sealing valve 81 and the partition. The partition is a thermal insulation material, which reduces the temperature interference between the preheating bin 11, the carbonization bin 12 and the activation bin 13, and ensures that the working effects of the preheating bin 11, the carbonization bin 12 and the activation bin 13 will not be affected. The preheating bin 11, the carbonization bin 12 and the activation bin 13 can process different batches of raw materials at the same time, thereby improving the working efficiency of the device. The gas generated by the raw materials in the preheating bin 11, the carbonization bin 12 and the activation bin 13 during the working process can be discharged through the exhaust groove 2. The exhaust device can collect the gas exhausted from the exhaust groove 2, so as to realize the recycling of the waste gas generated by the device, reduce the resource consumption and the pollution of the device to the external environment during the operation. The electric stirring rod 3 can stir the raw materials in the preheating bin 11 and the carbonization bin 12, improve the efficiency of preheating and carbonization of the raw materials, thereby improving the working efficiency of the device. The raw materials can be stirred by the electric stirring rod 3 to avoid agglomeration of the raw materials during the preheating process. The rotating electric stirring rod 3 can break up the raw materials during the movement of the raw materials inside the shell 1, and avoid the raw materials from piling up and affecting the movement of the raw materials inside the shell 1. The exhaust groove 2 is provided with a filter to avoid the inside of the preheating bin 11 and the carbonization bin 12. The raw materials leave the device through the exhaust groove 2 during the turning process, which avoids the waste of raw materials and improves the safety of the device. The storage pipe 15 arranged on the activation bin 13 is used to accommodate the raw materials entering the activation bin 13 from the carbonization bin 12. The storage pipe 15 reduces the time required for the device to activate the raw materials and improves the working efficiency of the device. The fan 7 is used to send hot air into the preheating bin 11, the carbonization bin 12 and the activation bin 13. The steam generator 6 is used to send water vapor into the activation bin 13. By setting a heating pipe 71 separately connected to the preheating bin 11, the carbonization bin 12 and the activation bin 13, the user can adjust the temperature of the gas sent into the preheating bin 11, the carbonization bin 12 and the activation bin 13 according to the actual use situation. The working effect of the device is guaranteed. The air inside the heating tube 71 is introduced into the interior of the preheating bin 11 and the carbonization bin 12 through the ventilation baffle 72, which further increases the contact area between the high-temperature gas and the raw materials, increases the heating rate of the raw materials, and thus improves the working efficiency of the device. The side wall of the ventilation baffle 72 is in the shape of a filter, which ensures the working effect of the ventilation baffle 72 while preventing the raw materials from entering the interior of the ventilation baffle 72. The position of the blades of the electric stirring rod 3 ensures the working effect of the electric stirring rod 3. The cooling mechanism 4 is used to cool the produced activated carbon. The through groove on the baffle is used for the movement of raw materials inside the device. The dividing block 8 can guide the moving raw materials to ensure that the raw materials will not accumulate on the baffle.

[0025] Specifically, the top surface of the dividing block 8 is an arc surface inclined toward the through groove, and the edge of the dividing block 8 is an arc shape.

[0026] The top surface shape of the dividing block 8 reduces the space occupied by the dividing block 8 while ensuring the working effect of the dividing block 8, thereby increasing the volume of the preheating bin 11 and the carbonization bin 12. The shape of the edge of the dividing block 8 ensures that after multiple dividing blocks 8 are installed on the partition, the raw materials will not accumulate on the top of the dividing block 8, thereby ensuring the working effect of the dividing block 8. The shape of the edge of the sealing valve 81 allows the blades of the electric stirring rod 3 to be as long as possible, thereby ensuring the working effect of the electric stirring rod 3.

[0027] Specifically, stepped through holes cooperating with the storage tube 15 are provided on the top and bottom side walls of the activation bin 13 , and a plurality of baffles 14 are staggeredly installed on the side walls of the activation bin 13 , and the storage tube 15 passes through the baffles 14 .

[0028] The stepped through hole is used to install the storage tube 15, ensuring the stability of the storage tube 15 after being installed on the activation bin 13. The baffle 14 is used to separate the space inside the activation bin 13. The space inside the activation bin 13 forms a curved air duct under the action of the baffle 14, thereby improving the working effect of the activation bin 13.

[0029] Specifically, the cooling mechanism 4 includes a storage bin 41, an air cooler 42, an air supply pipe 43, a net basket 44, an exhaust duct 45 and a placement groove 46. Several electric rollers are installed on the bottom surface of the storage bin 41. Two placement grooves 46 are provided inside the storage bin 41. The net basket 44 is installed on the placement groove 46. Two grooves are provided on the side wall of the storage bin 41. Several through grooves connected to the side wall grooves of the storage bin 41 are provided on the side wall of the placement groove 46. The air cooler 42 is installed with an air supply pipe 43. The air supply pipe 43 matches the side wall groove of the storage bin 41. An electric valve is provided on the branch pipe of the air supply pipe 43.

[0030] The electric roller on the storage bin 41 is convenient for the user to move the storage bin 41, reducing the physical exertion of the user when storing the bin 41. The placement slot 46 is used to install the net basket 44, and the net basket 44 is detachable, which is convenient for the user to take out the cooled activated carbon from the storage bin 41. The side wall grooves on the storage bin 41 are respectively connected to the two placement slots 46. The cold air in the air cooler 42 can be sent into the interior of the placement slot 46 through the cooperation of the air supply pipe 43 and the side wall grooves of the storage bin 41. The cold air in the air cooler 42 will be ejected through the side wall through groove of the placement slot 46, so that the cooling mechanism 4 can cool down various positions of the net basket 44, thereby improving the cooling efficiency. The working efficiency of the mechanism 4 is improved. The shape of the side wall of the net basket 44 ensures that the air ejected from the placement groove 46 will not be hindered by the net basket 44. The electric valve arranged on the air supply pipe 43 can control the position of the cold air ejected from the air supply pipe 43, thereby avoiding the waste of cold air. Two placement grooves 46 are arranged on the storage bin 41. When the activated carbon is cooled by the cooling mechanism 4, the placement groove 46 without activated carbon is located below the outer shell 1, which is convenient for the user to collect the activated carbon discharged from the outer shell 1. When the cooling mechanism 4 cools the activated carbon, the net basket 44 containing activated carbon is located outside the outer shell 1, which is convenient for the user to remove the net basket 44 containing the cooled activated carbon.

[0031] Specifically, a symmetrical slide rail 5 is provided below the housing 1 , and a groove matching the bottom roller of the storage bin 41 is provided on the top surface of the slide rail 5 .

[0032] The slide rail 5 is used for moving the material storage bin 41, and the groove on the top surface of the slide rail 5 plays a limiting role. The positions of the two ends of the groove on the top surface of the slide rail 5 are the positions of the electric roller of the material storage bin 41 when the material storage bin 41 is connected to the air supply pipe 43. The groove on the top surface of the slide rail 5 enables the user to quickly move the material storage bin 41 to a suitable position, thereby improving the efficiency of the user in adjusting the position of the material storage bin 41.

[0033] Specifically, the distance between the openings at both ends of the air supply pipe 43 is the distance between the side wall grooves of the storage bin 41 when the storage bin 41 moves to the limit position.

[0034] The position of the opening of the branch pipe of the air supply pipe 43 ensures that when one placement slot 46 is connected to the air supply pipe 43, the other placement slot 46 is located directly below the outer shell 1, ensuring the ability of the net basket 44 to collect the activated carbon discharged from the outer shell 1.

[0035] Specifically, the exhaust groove 2 connected to the activation chamber 13 is located at the top of the side wall of the activation chamber 13 , and the position where the activation chamber 13 is connected to the heating pipe 71 is located at the bottom of the side wall of the activation chamber 13 .

[0036] The positions of the exhaust groove 2 and the heating pipe 71 connected to the activation bin 13 ensure that the high-temperature air and water vapor sent into the activation bin 13 can move along the air passage separated by the baffle 14 of the activation bin 13, thereby preventing the air sent into the activation bin 13 from being discharged from the device through the exhaust groove 2 in advance, and ensuring that the water vapor and hot air sent into the activation bin 13 can fully contact with the raw materials.

[0037] The working principle and use process of the utility model are as follows: the raw materials are placed in the preheating bin 11, the steam generator 6, the fan 7 and the heating tube 71 are started, hot air and water vapor are sent into the interior of the shell 1, and the electric stirring rod 3 is started to stir the raw materials in the preheating bin 11. After the preheating is completed, the sealing valve 81 on the partition separating the preheating bin 11 and the carbonization bin 12 is opened, and the preheated raw materials enter the carbonization bin 12, and the sealing valve 81 between the preheating bin 11 and the carbonization bin 12 is closed, and new raw materials are sent into the preheating bin 11, and the raw materials are carbonized in the carbonization bin 12, and the sealing valve 81 between the carbonization bin 12 and the activation bin 13 is opened, and the carbonized raw materials enter the storage pipe 15, and the sealing valve 81 between the carbonization bin 12 and the activation bin 13 is closed, and the sealing valve 81 between the preheating bin 11 and the carbonization bin 12 is opened, and the raw materials in the preheating bin 11 enter the carbonization bin 12, and the preheating bin 11 and the activation bin 13 are closed. The sealing valve 81 between the carbonization bins 12 delivers new raw materials into the preheating bin 11. After the activation of the raw materials is completed, the sealing valve 81 at the bottom of the shell 1 is opened, and the activated carbon enters the net basket 44. After the activated carbon is completely discharged, the sealing valve 81 at the bottom of the shell 1 is closed, and the above actions are repeated. By controlling the opening and closing of the sealing valve 81, the movement of the raw materials inside the preheating bin 11, the carbonization bin 12 and the activation bin 13 is controlled. After the activated carbon is completely discharged, the storage bin 41 is moved by the electric roller of the storage bin 41. When the air supply pipe 43 is connected to the placement tank 46 filled with activated carbon, the electric valve on the pipeline connected to the placement tank 46 is opened, and the air cooler 42 is started. The cold air inside the air cooler 42 passes through the air supply pipe 43, the side wall groove of the storage bin 41 and the side wall through-groove of the placement tank 46 and then blows onto the activated carbon in the net basket 44. After the activated carbon is cooled, the net basket 44 is replaced.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
