Description

Technical Field

[0001] This utility model relates to the field of graphene drying technology, specifically a continuous drying device for the production of graphene soil conditioners. Background Technology

[0002] Graphene is a novel material with a single-layer two-dimensional honeycomb lattice structure in which carbon atoms are closely packed together in sp2 hybridization. Graphene has excellent optical, electrical, and mechanical properties and has important application prospects in materials science, micro-nano fabrication, energy, biomedicine, and drug delivery. It is considered a revolutionary material for the future. There are various ways to produce graphene. For example, in the Hermès process, graphene oxide needs to be treated and dissolved in a specific solvent. After a specific chemical reaction, the mixture is filtered, washed, and dried to obtain graphene.

[0003] Chinese patent CN220852914U discloses a drying device for graphene powder material production. This technical solution involves starting a first motor, which drives a rotating shaft to rotate. The rotating shaft then drives multiple sets of flippers to rotate, thereby turning and drying the graphene powder material inside the drum. Simultaneously, the rotating shaft also drives a connector to rotate, which in turn drives a rotating seat. The rotating seat then drives three sets of scrapers to rotate, effectively scraping up the graphene powder material accumulated at the bottom of the drum's inner cavity. This effectively avoids uneven drying caused by the accumulation of graphene powder material. Therefore, this design allows for highly efficient drying of the graphene powder material, effectively avoiding energy waste and significantly improving processing efficiency.

[0004] However, during the use of this continuous drying device for graphene soil conditioning production, the hot airflow after drying is directly discharged. The suspended particulate matter and harmful substances carried in the airflow are directly discharged into the atmosphere, which can easily aggravate air pollution. Furthermore, the direct discharge of heat carried by the hot airflow can easily lead to resource waste. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a continuous drying device for graphene soil conditioning production, which solves the problem that the hot airflow after drying is directly emitted during use, easily exacerbating air pollution.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a continuous drying device for graphene soil conditioning production, including a base, a drying tank vertically arranged on the base, a filter box fixedly connected to the rear side of the top of the base, a recovery tank connected to the top of the filter box, a connecting pipe provided at the top of the recovery tank, and the other end of the connecting pipe connected to the top of the inner cavity of the drying tank.

[0007] The inner cavity of the recycling tank is provided with a serpentine tube, the upper part of the inner cavity of the filter box is provided with a filter screen plate, the lower part of the inner cavity of the filter box is provided with an activated carbon plate, the bottom of the rear side of the filter box is provided with an exhaust window, and the bottom of the base is provided with a fan mechanism that draws in external airflow and heats and injects it into the inner cavity of the drying tank.

[0008] Furthermore, the inner cavity of the drying tank is equipped with a stirring assembly, and the front side of the base is equipped with a control panel.

[0009] Furthermore, the base is provided with several support feet at its bottom, the drying tank is provided with a discharge pipe at its bottom, and a valve is provided on the discharge pipe.

[0010] Furthermore, the front side of the drying tank is provided with an inspection door, and the inspection door is provided with a latch that is compatible with the base.

[0011] Furthermore, the top of the rear side of the recycling tank is provided with a water inlet pipe that communicates with the top end of the serpentine pipe, and the bottom of the rear side of the recycling tank is provided with a water outlet pipe that communicates with the bottom end of the serpentine pipe.

[0012] Furthermore, the fan mechanism includes a connecting seat, a hot air blower, and an air outlet pipe. The connecting seat is disposed on the surface of the base, the hot air blower is fixedly connected to the top of the connecting seat, the air outlet pipe is disposed at the air outlet of the hot air blower, and the other end of the air outlet pipe communicates with the inner cavity of the drying tank.

[0013] Furthermore, the air inlet of the hot air blower is connected to an air inlet pipe, and a filter cover is provided at the other end of the air inlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: after the fan mechanism works, the graphene soil conditioner in the inner cavity of the drying tank can be dried and processed. The waste gas generated during the drying process enters the inner cavity of the recovery tank through the connecting pipe. Water is circulated into the inner cavity of the serpentine tube to recover the heat carried in the waste gas. The hot air after heat recovery enters the inner cavity of the filter box. The filter screen filters the suspended particles in the airflow, and the activated carbon plate filters and purifies the harmful substances carried in the airflow. Finally, it is discharged through the exhaust window, reducing pollution to the surrounding environment of the device, improving the physical protection of the personnel around the device, recovering the heat of the waste gas, and reducing the industrial production cost.
