They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 5 As shown, this utility model embodiment includes a main unit module 1 and an auxiliary unit module 2 connected by a feed hose 3 and a discharge hose 4. The main unit module 1 is based on a thermal insulation barrel assembly 101. A coil assembly 102 is arranged vertically inside the thermal insulation barrel assembly 101. The bottom feed end of the coil assembly 102 is connected to the feed hose 3, and the top discharge end is connected to the discharge hose 4. A first electric heater 103 and a fan are arranged at the bottom inside the thermal insulation barrel assembly 101 to heat the coil assembly 104. A temperature sensor 105 is also provided to detect the temperature inside the thermal insulation barrel assembly 101 in real time.

[0022] Auxiliary module 2 uses frame 201 as its outer frame. Inside frame 201, at the bottom, air inlet cabinet assembly 207 and vortex fan assembly 2015 are fixed with bolts. Bag filter assembly 208 is connected via shaft 2013, and cyclone dust collector assembly is connected via quick-connect coupling. Cyclone dust collector assembly and bag filter assembly 208 are connected via cyclone-bag section duct assembly 2011. Vortex fan assembly 2015 is connected to bag filter assembly 208 via bag-fan section. Piping assembly 2012 is connected; a star valve 202 is installed on the frame 201 to connect to the external material receiving equipment. The star valve 202 is connected to the feed hose 3 through the feed section piping assembly 2018, and the feed section piping assembly 2018 is connected to the air inlet cabinet assembly 207 to introduce hot air to send the material into the coil assembly 102 for drying; the discharge hose 4 is connected to the cyclone dust collector assembly through the discharge section piping assembly 2019 to collect the material after drying.

[0023] The air inlet cabinet assembly 207 includes a surface condenser 2024, a high-temperature resistant medium-efficiency filter 2023, a second electric heater 2022, and a high-temperature resistant high-efficiency filter 2021 arranged in sequence. A temperature and humidity sensor 2020 is installed at the connection between the air inlet cabinet assembly 207 and the feed section pipeline assembly 2018 to convert the outside air into dry and clean hot air and send it into the feed section pipeline assembly 2018.

[0024] The cyclone dust collector assembly includes a primary cyclone separator 203 and a secondary cyclone separator 204. The primary cyclone separator 203 is connected to the discharge section pipeline assembly 2019 through the primary cyclone inlet pipe 2016 and to the secondary cyclone separator 24 through the secondary cyclone inlet pipe 205. The secondary cyclone separator 204 is connected to the bag filter dust collector assembly 208 through the cyclone-bag section pipeline assembly 2011. It is used to collect materials and send the few fine particles and dust that are not collected into the bag filter dust collector assembly 208 for collection. A moisture meter 206 is installed at the bottom discharge end of the primary cyclone separator 203 to detect the moisture content of the finished material in real time.

[0025] The frame 201 is equipped with a back-blowing air manifold assembly 2010 and a pulse solenoid valve 2017, which are connected to the bag filter assembly 208 and are used to perform pulse cleaning on the bag filter assembly 208. The bottom of the bag filter assembly 208 is equipped with a collection tank 209 for collecting the cleaned fine particles and dust.

[0026] When material drying is required, the vortex blower assembly 2015 first starts operating at a certain frequency, and the second electric heater 2022 inside the air inlet cabinet assembly 207 also starts running for preheating. When the preheating temperature measured by the temperature sensor 105 reaches about 85℃, the external chiller is turned on to inject 7℃ cold water into the surface condenser 2024. When the humidity measured by the temperature and humidity sensor 2020 on the air inlet cabinet assembly 207 is converted to an absolute humidity of about 10g / kg, the material is controlled by the star valve 202 to enter the system for drying. Here, the star valve 202 can change the rotation speed to control the feeding rate. The air inlet cabinet assembly 207 is also equipped with a high-temperature resistant medium-efficiency filter 2023 and a high-temperature resistant high-efficiency filter 2021 to provide dry and clean hot air carrying the material. The material is dried via the feed section piping assembly 2018 and the coil assembly 102, then reaches the cyclone dust collector assembly via the discharge section piping assembly 2019. The cyclone dust collector assembly includes two-stage collection, which collects the majority of the dried material. A small amount of fine particles and dust that are not collected reaches the bag filter assembly 208 via the cyclone-bag section piping assembly 2011. These particles are blocked by 20µm filter bags and successfully collected in the collection tank 209 at the bottom of the bag filter assembly 208 under the control of the pulse solenoid valve 2017. The clean hot air then reaches the vortex blower assembly 2015 via the bag-fan section piping assembly 2012 and is directly discharged from the system through the blower outlet pipe 2014, ensuring the recovery rate of the finished material and reducing air pollution. Pneumatic butterfly valves are installed in each of the aforementioned piping assemblies and the cyclone dust collector assembly, and the opening and closing of these valves are automatically controlled by a PLC.

[0027] Preferably, the coil assembly 102 consists of three coils distributed inside and outside, which can effectively increase the pipe length and extend the drying time of the particles.

[0028] As a preferred option, the bottom and top of the insulated bucket assembly 101 adopt an elliptical or hemispherical end cap design, which plays an important role in guiding the flow and is more conducive to the stable operation of the airflow inside the bucket, thereby ensuring a uniform internal temperature distribution. In addition, the insulated bucket assembly 101 is insulated with aluminum silicate insulation cotton.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
