Technical Field
[0001] The utility model relates to the technical field of activated carbon drying, in particular to an activated carbon drying device. Background Art
[0002] In the production process of activated carbon, the activated carbon will be dried. Drying can improve the adsorption capacity and stability of activated carbon, and at the same time can remove impurities and moisture, thereby improving its quality and efficiency. At present, the drying process is to stack the activated carbon in the drying barrel and then send hot air from the bottom to the top of the barrel for drying. However, in the existing hot air drying device during drying, the hot air cannot evenly contact the stacked activated carbon, which is likely to cause local wetness and affect the drying effect of the activated carbon. And during the hot air drying process, the dust on the surface of the activated carbon will also float around with the hot air, causing environmental pollution and affecting people's breathing. Therefore, an activated carbon drying device is designed to solve the above problems. Summary of the Utility Model

The outer wall of the barrel body is provided with a ventilation component and a diffusion cover. The bottom of the barrel body is provided with a sprinkling component for stirring the activated carbon. The top of the barrel body is provided with a detachable barrel cover. A replaceable filter screen is arranged between the barrel cover and the barrel body. There is an exhaust port communicating with the ventilation component between the barrel cover and the filter screen. A plurality of drying pipes are radially arranged in the barrel body. One end of the drying pipe penetrates the barrel body. The outer wall of the drying pipe has a plurality of tapered air outlet holes. The diffusion cover covers the end of the drying pipe penetrating the barrel body. A heating sheet for heating gas is arranged in the diffusion cover. One side of the diffusion cover has an air inlet connected to a heat exchange component. The heat exchange component is used for sucking dry and high-temperature gas into the barrel body and discharging the wet gas in the barrel body.
[0005] Preferably, the ventilation component includes a housing, an exhaust turbine, an intake turbine and a brushless motor. The housing is fixed on the outer wall of the barrel body. The top of the housing is rotatably connected with an exhaust turbine. The bottom of the housing has an intake turbine. The exhaust turbine and the intake turbine are coaxial.

When the driving motor is started, the eccentric wheel drives the connecting rod to do reciprocating piston motion, and the rubber membrane continuously expands and contracts under the drive of the connecting rod, so that the activated carbon in the barrel is sprinkled up and down under the drive of the rubber membrane. During the sprinkling process, the activated carbon is in full contact with the hot gas ejected from the drying pipe, so as to prevent the local wetting of the activated carbon.
[0008] Preferably, there is also an air pressure balance hole between the bottom of the barrel body and the rubber membrane, and a side door for discharging materials is also arranged on the outer side of the barrel body.
[0009] The beneficial effects of the present utility model are as follows: 1.

During the sprinkling process, the activated carbon is in full contact with the hot gas ejected from the drying pipe, so as to prevent the local wetting of the activated carbon. 2. When the ventilation assembly works, the exhaust turbine sucks the wet gas with dust in the barrel body from the exhaust inlet. During the suction process, the dust in the gas is filtered by the filter screen between the barrel cover and the barrel body, so as to prevent the dust from spreading everywhere.

The outer wall of the drying pipe 7 has a plurality of conical air outlet holes 71. The diffusion cover 6 wraps the end of the drying pipe 7 penetrating the barrel body 1 inside. A heating sheet 8 for heating gas is provided inside the diffusion cover 6. One side of the diffusion cover 6 has an air inlet connected to a heat exchange component. The heat exchange component is used to inhale dry and high-temperature gas into the barrel body 1 and discharge the moist gas inside the barrel body 1;
[0020] The ventilation component 2 includes a housing 21, an exhaust turbine 22, an intake turbine 23, and a brushless motor 24. The housing 21 is fixed to the outer wall of the barrel 1. The top of the housing 21 is rotatably connected to the exhaust turbine 22. The bottom of the housing 21 is provided with the intake turbine 23. The exhaust turbine 22 and the intake turbine 23 are coaxial. The exhaust turbine 22 and the intake turbine 23 are driven by a brushless motor 24 disposed in the middle of the housing 21.
[0021] The housing 21 has an exhaust inlet corresponding to the axis of the exhaust turbine 22, an exhaust outlet corresponding to the radius of the exhaust turbine 22, an intake inlet corresponding to the axis of the intake turbine 23, and an intake outlet corresponding to the radius of the intake turbine 23. The exhaust inlet is communicated with the exhaust port of the barrel cover 3, and the intake outlet is communicated with the intake port of the diffusion hood 6. When the brushless motor 24 is started, the exhaust turbine 22 and the intake turbine 23 rotate at high speed. The exhaust turbine 22 sucks the moist gas with dust in the barrel 1 from the exhaust inlet. During the suction process, the dust in the gas is filtered by the filter screen 4 between the barrel cover 3 and the barrel 1, thereby preventing the dust from spreading everywhere. The intake turbine 23 sucks the outside dry gas into the diffusion hood 6 for heating, and the heated gas enters the barrel 1 through the drying pipe 7 to dry the activated carbon.
[0022] The sprinkling component 5 includes a driving motor 51, an eccentric wheel 52, a connecting rod 53, a hinge block 54, and a rubber membrane 55.

The rubber membrane 55 is disposed in the barrel 1 to separate the driving motor 51 and the drying pipe 7. The hinge block 54 is disposed at the center of the bottom end face of the rubber membrane 55. One end of the connecting rod 53 is hinged to the hinge block 54, and the other end of the connecting rod 53 is hinged to one side of the eccentric wheel 52. When the driving motor 51 is started, the eccentric wheel 52 drives the connecting rod 53 to perform a reciprocating piston motion. The rubber membrane 55 continuously expands and contracts under the drive of the connecting rod 53, so that the activated carbon in the barrel is sprinkled up and down under the drive of the rubber membrane 55. During the sprinkling process, the activated carbon is in full contact with the hot gas sprayed from the drying pipe 7, thereby preventing the local wetting of the activated carbon.
[0023] There is also a pressure balance hole between the bottom of the barrel 1 and the rubber membrane 55. There is also a side door 9 for discharging materials on the outside of the barrel.
[0024] Through the above settings, in the actual working process, its specific working principle is as follows:
[0025] First, open the barrel cover 3 and take out the filter screen 4, and then put the activated carbon to be dried into the barrel 1. After the activated carbon is put in, restore the filter screen 4 and the barrel cover 3 to the initial state.
[0026] After the activated carbon is placed, start the drive motor 51 and the brushless motor 24. The brushless motor 24 drives the exhaust turbine 22 and the intake turbine 23 to rotate at high speed. The exhaust turbine 22 sucks the moist gas with dust in the barrel body 1 from the exhaust inlet. During the suction process, the dust in the gas is filtered by the filter screen 4 between the barrel cover 3 and the barrel body 1, thereby preventing the dust from spreading everywhere; the intake turbine 23 sucks the external dry gas into the diffusion hood 6 for heating, and the heated gas enters the barrel body 1 through the drying pipe 7 to dry the activated carbon.
[0027] After the drive motor 51 is started, it drives the eccentric wheel 52 to rotate. The eccentric wheel 52 drives the connecting rod 53 to make a reciprocating piston motion. The rubber membrane 55 continuously expands and contracts under the drive of the connecting rod 53, so that the activated carbon in the barrel is thrown up and down under the drive of the rubber membrane 55. During the throwing process, the activated carbon is in full contact with the hot air ejected from the drying pipe 7, thereby preventing the local wetting of the activated carbon.
[0028] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
