Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon dryers, in particular to a special dryer for spontaneous combustion-proof activated carbon. Background Art

[0002] Activated carbon has been widely used in many fields due to its excellent adsorption capacity and porous structure, such as water treatment, air purification, desulfurization, denitrification and other industrial processes. However, there are certain safety hazards in the production and storage of activated carbon, especially in the drying process. Due to its high adsorption performance and porosity, activated carbon easily absorbs and accumulates heat. In addition to its own flammability, it is easy to spontaneously combust under inappropriate conditions. Spontaneous combustion may not only cause damage to production equipment, but also cause fires, seriously threatening production safety and the safety of life and property of personnel. In order to prevent the spontaneous combustion of activated carbon, traditional drying equipment usually relies on manual temperature monitoring and manually opening the discharge port to reduce the temperature when necessary. However, this method is time-consuming and error-prone, and it cannot respond to temperature changes in time, so it cannot effectively prevent the occurrence of spontaneous combustion events. To solve this problem, we have developed a special dryer for anti-spontaneous combustion activated carbon. This dryer can monitor the temperature of activated carbon in real time and automatically open the discharge port when the temperature is close to the autoignition point, thereby effectively preventing the occurrence of spontaneous combustion.

[0005] Therefore, it is necessary to design a special dryer for activated carbon that is highly practical and has automatic detection and can prevent spontaneous combustion. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a special dryer for anti-spontaneous combustion activated carbon, including a drying box 1, a motor 2 is fixedly connected to one side of the drying box 1, a rotating shaft 21 is arranged at the output end of the motor 2, an intermittent mechanism is connected to one side of the rotating shaft 21, a reciprocating mechanism is connected to one side of the intermittent mechanism, a folding block 28 is connected to one side of the reciprocating mechanism, a feed port 11 is fixedly connected to the top of the drying box 1, the folding block 28 is located in the middle of the feed port 11, a protective block 15 is fixedly connected to one side of the drying box 1, a storage plate 13 is fixedly connected to the interior of the drying box 1, and a push plate 13 is correspondingly provided on one side of the storage plate 13. A conveying mechanism, a notch 12 is provided on one side of the drying box 1, and an opening and closing mechanism is provided inside the notch 12. A humidity sensor and a temperature sensor are connected to one side of the storage plate 13. The temperature sensor corresponds to the opening and closing mechanism, and the humidity sensor corresponds to the pushing mechanism. A conveyor belt 5 is provided on one side of the drying box 1, and the conveyor belt 5 corresponds to the notch 12. When the staff is ready to start the activated carbon drying work, the activated carbon is first added from the feed port 11, and then the staff turns on the motor 2 to drive the rotating shaft 21 to rotate, and the intermittent mechanism drives the reciprocating mechanism to move, and the reciprocating mechanism drives the folding block 28 changes from the unfolded state to the folded state, which is equivalent to the feed port 11 being opened. When the intermittent mechanism moves, the feed port 11 is opened, and the motor 2 continues to drive. At this time, the intermittent mechanism does not move, and the reciprocating mechanism does not move. During this interval, the activated carbon is added to the inside, and when the intermittent mechanism moves with the reciprocating mechanism again, the reciprocating mechanism unfolds with the folding block 28, that is, the feed port 11 is closed. At this time, the motor 2 is turned off, and the activated carbon falls onto the storage plate 13 under the action of gravity. At this time, the drying box 1 dries it. At this time, the humidity sensor and the temperature sensor are inside the activated carbon. When the temperature inside the activated carbon is too high and it is easy to self-ignite, the temperature sensor will sense it. The temperature sensor can convert the detected environmental conditions into electrical signals, which are then transmitted to the control system. The control system then controls the opening and closing mechanism to open the movable plate 42 on one side of the drying box 1. At the appropriate temperature, the activated carbon is slowly dried. At this time, the humidity sensor detects the appropriate humidity and transmits it to the control system. The control system starts the pushing mechanism. At this time, the opening and closing mechanism also opens the movable plate 42 to push the activated carbon onto the conveyor belt 5 for automatic unloading. By providing a humidity sensor, the humidity sensor can accurately detect the humidity of the activated carbon. When the preset suitable humidity is reached, the pushing mechanism will be triggered to push the activated carbon to the conveyor belt 5 for automatic unloading, thereby ensuring the dry quality of the product. By providing a temperature sensor, when the temperature approaches the auto-ignition point of the activated carbon, the temperature sensor will immediately sense and transmit the signal to the control system, and the control system will then control the opening and closing mechanism to open the movable plate 42, timely reduce the temperature, thereby effectively preventing the activated carbon from self-igniting, and significantly improving the safety of the production process.

[0026] The intermittent mechanism includes a first gear 22, the first gear 22 is fixedly connected to the rotating shaft 21, a second gear 23 is meshedly connected to one side of the first gear 22, an L-shaped block is fixedly connected to one side of the drying box 1, the L-shaped block is rotatably connected to the second gear 23, and the second gear 23 is connected to the reciprocating mechanism; when the staff turns on the motor 2, the rotating shaft 21 at the output end rotates, driving the first gear 22 to rotate, so that the second gear 23 meshed with it rotates, and the second gear 23 and the L-shaped block are rotatably connected, so they can rotate, so that the reciprocating mechanism can also operate. By setting up the intermittent mechanism, the frequency of the motor 2 is constant, and the frequency of the intermittent mechanism stopping and moving is constant, so that the time for the feed port 11 to be opened is certain, and the amount of activated carbon fed can be controlled to ensure that the interior is fully dried.

[0027] The first gear 22 is an incomplete gear; the first gear 22 has only half of the teeth, and the half with teeth drives the second gear 23 to rotate and drives the reciprocating mechanism to move, that is, the feed port 11 is opened, and the half without teeth, the second gear 23 does not rotate, so that the reciprocating mechanism stops, and the feed port 11 remains open, and then moves to the toothed part, the feed port 11 is closed, and the amount of activated carbon fed is controlled to ensure sufficient internal drying.

[0028] The reciprocating mechanism comprises a round block 24, the round block 24 is fixedly connected to the second gear 23, a protrusion 25 is fixedly connected to one side of the round block 24, an O-shaped block 26 is slidably connected to the outer side of the protrusion 25, a cross bar 27 is fixedly connected to one side of the O-shaped block 26, and the cross bar 27 is fixedly connected to the folding block 28; when the second gear 23 rotates, the round block 24 at the top will rotate, and the protrusion 25 will rotate accordingly, and the protrusion 25 will slide inside the O-shaped block 26. When sliding to the end of the O-shaped block 26, it can no longer continue to slide inside, but the protrusion 25 still has to continue to rotate, so that the protrusion 25 moves with the O-shaped block 26, so the round block 24 rotates in circles, so the O-shaped block 26 moves back and forth, and moves back and forth with the cross bar 27, so that the folding block 28 at the bottom can be opened and closed, and then opened and closed, and the folding block 28 is connected to the feed port 11, and the folding block 28 will not fall off, and the folding block 28 provides a certain support force for the O-shaped block 26. By providing the reciprocating mechanism, the folding block 28 can be opened and closed without the need for the motor 2 to rotate forward or reverse, thereby extending the service life of the motor 2.

[0029] The pushing mechanism includes a first cylinder 3, which is fixedly connected to the drying box 1. The output end of the first cylinder 3 is connected to a first piston rod 31, and one side of the first piston rod 31 is fixedly connected to a push block 32, which corresponds to the storage plate 13. When the controller controls the first cylinder 3 to open, the first piston rod 31 extends, and the push block 32 is pushed to the other side. At this time, the push block 32 removes the activated carbon on the storage plate 13 from the drying box 1. The two ends of the push block 32 are in contact with the storage plate 13, so that all the activated carbon can be pushed out of the device. By providing a pushing mechanism, when the activated carbon inside is dried to a certain degree, the device can automatically unload the material, which reduces manpower and improves work efficiency.

[0030] The opening and closing mechanism includes a second cylinder 4, and grooves 14 are provided around the inside of the slot 12. The second cylinder 4 is fixedly connected to the bottom of the groove 14. The output end of the second cylinder 4 is connected to a second piston rod 41, and one side of the second piston rod 41 is fixedly connected to a movable plate 42; when the temperature sensor triggers the second cylinder 4 to open, the second piston rod 41 retracts, and the movable plate 42 that originally blocked the slot 12 moves downward and no longer blocks the slot 12. In this way, the outlet is opened, air can circulate, the internal temperature is reduced, and the activated carbon is prevented from spontaneous combustion.

[0031] Rubber is fixedly connected to both sides of the groove 14, and the movable plate 42 is in the middle of the rubber; the rubber ensures the sealing of the drying box 1, and when the movable plate 42 is closed, the movable plate 42 is completely inside the rubber to maintain sealing.
