Description

Technical Field

[0001] This utility model relates to the field of activated carbon processing technology, and in particular to an activated carbon raw material drying device. Background Technology

[0002] Activated carbon, also known as activated carbon, is amorphous carbon that exists in black powder, block, granular, or honeycomb form, and can also be arranged in regular crystalline form. Besides carbon, activated carbon contains two types of impurities: one type consists of chemically bonded elements, primarily oxygen and hydrogen. These elements remain in the carbon due to incomplete carbonization, or are introduced during activation by non-carbon elements chemically bonding to the activated carbon surface, such as during steam activation, where the activated carbon surface is oxidized. The other type of impurity is ash, the inorganic component of activated carbon. Ash can easily cause secondary pollution in activated carbon, and therefore needs to be dried during production.

[0059] A guide slope is provided at the end of the sealing block 24 near the end of the connecting pipe 20.

[0060] A first electric push rod 21 is fixedly installed on the top inner wall of the housing 1, with the telescopic shaft of the first electric push rod 21 facing downwards vertically. A connecting rod is fixedly installed radially on the telescopic shaft of the first electric push rod 21, and the connecting rod is fixedly connected to the connecting tube 20.

[0061] An exhaust port is vertically opened on the top of the housing 1. The exhaust port connects to the interior of the housing 1 and is connected to existing waste gas collection and treatment equipment. This is existing technology and will not be described in detail here.

[0062] Working principle: When using this device to dry activated carbon raw materials, start the first electric push rod 21. The telescopic shaft of the first electric push rod 21 extends downward and drives the connecting rod to move downward. The connecting rod drives the connecting pipe 20 to extend downward from the extension tube 3 and gradually insert into the docking hole of the second drying cylinder 19.

[0063] After the connecting pipe 20 is inserted into the docking hole, it gradually approaches the sealing block 24 and eventually causes the first magnet 25 to engage with the second magnet 26. Then, the connecting pipe 20 pushes the sealing block 24 downwards until it exits the docking hole and enters the drying cavity 22 of the second drying cylinder 19. During this process, the sealing block 24 causes the two fourth magnets 32 to disengage from their corresponding third magnets 27.

[0064] Next, activated carbon raw material is added into the feed pipe 2. The activated carbon raw material then passes through the extension pipe 3 and the connecting pipe 20, finally entering the second drying cylinder 19 along the guide slope on the sealing block 24. It should be noted that to ensure the activated carbon raw material is pulverized, a pulverizer for pulverizing the activated carbon raw material can be installed in the feed pipe 2; this is existing technology and will not be elaborated upon here. The attraction force between the first magnet 25 and the second magnet 26 is much greater than the impact force of the activated carbon raw material impacting the sealing block 24.

[0065] After the activated carbon raw material is added, the first electric push rod 21 is activated again, and the telescopic axis of the first electric push rod 21 retracts upward. The connecting pipe 20, through the first magnet 25 and the second magnet 26, moves the sealing block 24 upward back to the docking hole. When the two fourth magnets 32 on the sealing block 24 are attracted to the corresponding third magnets 27 again, the connecting pipe 20 moves the first magnet 25 away from the second magnet 26 until it moves back to its original position.

[0066] Subsequently, motor 4 is started, and the output shaft of motor 4 drives the second drying cylinder 19 to rotate. The second drying cylinder 19 drives the first drying cylinder 18 to rotate synchronously through several transmission shafts 31. During this process, electric heater 23 heats the activated carbon raw material. At the same time, the activated carbon raw material flows back and forth in the two drying chambers 22, and the inner walls of the first drying cylinder 18 and the second drying cylinder 19 cause the activated carbon raw material to tumble back and forth through friction.

[0067] After the drying operation is completed, the second electric push rod 29 is activated. The telescopic shaft of the second electric push rod 29 pushes the slider to slide along the support guide rail 16. The slider drives the support rod, the support rod drives the transmission ring 17, the transmission ring 17 pushes the fixed ring, and the fixed ring drives the first drying cylinder 18 away from the second drying cylinder 19. During this process, the first drying cylinder 18 stretches all the springs 30; at the same time, the slider drives the push block, the push block drives the rack 14, the rack 14 drives the gear 11 to rotate; the gear 11 drives the one-way bearing to rotate freely.

[0068] As the first drying cylinder 18 moves away from the second drying cylinder 19, the first drying cylinder 18 and the second drying cylinder 19 continue to rotate synchronously. During the reciprocating flow of the activated carbon raw material within the two drying chambers 22, it falls from the gap between the first drying cylinder 18 and the second drying cylinder 19 into the material carrier box 6.

[0069] After all the activated carbon raw materials have entered the material container 6, the telescopic shaft of the second electric push rod 29 retracts. The first drying cylinder 18 approaches the second drying cylinder 19 until they are reconnected. During this process, the rack 14 drives the gear 11 to reverse, the gear 11 drives the one-way bearing to rotate, the one-way bearing drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the first bevel gear 10 to rotate, the first bevel gear 10 drives the second bevel gear 12 to rotate, the second bevel gear 12 drives the reciprocating screw 28 to rotate, and the reciprocating screw 28 drives the extension plate to move back and forth. At this time, the extension plate drives the pusher plate 13 to first slide close to the discharge port 5 to push the activated carbon raw materials out of the material container 6, and then slide away from the discharge port 5 until it returns to its original position.

[0070] Finally, when the docking hole on the second drying drum 19 is directly below the connecting pipe 20, the motor 4 can be turned off. It should be noted that the motor 4, the first electric push rod 21, and the second electric push rod 29 can all be manually controlled via operating buttons. Additionally, the housing 1 can be made of transparent material. Specific control methods will be optimized based on existing technology during actual production processes and will not be elaborated upon here.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
