The drying device for processing chemical products adds chemical products into the drying box through a feed tube, dries the chemical products in the drying box through a heating pipe and a heating assembly, and simultaneously starts the motor to drive the stirring rod to rotate so that the chemical products are heated evenly. When the chemical products generate water vapor, an air pump is started to extract the water vapor through an exhaust pipe and discharge it into a purification box through a connecting pipe. The gas is purified by a filter plate and finally discharged through an exhaust pipe, thereby effectively ensuring the safety of the drying box for processing chemical products. When the filter plate needs to be replaced, the filter plate can be removed and replaced by opening a second sealing cover and removing the bolts from the fixing platform.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4 The utility model provides a drying device for processing chemical products, including a drying box 1, a fan 2 is fixedly installed at the bottom of the inner cavity of the drying box 1, a plurality of ventilation grooves 3 are opened at the bottom of the drying box 1, a fixed cylinder 4 is fixedly installed at the bottom of the drying box 1 and outside the ventilation grooves 3, a heating wire 5 is fixedly installed in the inner cavity of the fixed cylinder 4, a feed pipe 14 is connected to the top of the drying box 1, a pipe cover 15 is installed on the top of the feed pipe 14, a discharge pipe 16 is connected to one side of the drying box 1, and a control valve 17 is installed on the top of the discharge pipe 16.

[0022] By cooperating with the fan 2 and the heating wire 5, the fan 2 can draw external air into the interior of the fixed cylinder 4. After being heated by the heating wire 5, the air enters the interior of the drying box 1 through the ventilation groove 3 to heat and dry the chemical products. Through the setting of the feed pipe 14, the user can feed the chemical products into the drying box 1 through the feed pipe 14 for drying. After the feeding is completed, the user can seal the feed pipe 14 with the pipe cover 15. Through the setting of the discharge pipe 16, the dried chemical products can be discharged from the drying box 1. The setting of the control valve 17 can control the opening and closing of the discharge pipe 16.

[0023] Preferably, a stirring assembly for improving the heating uniformity of chemical products is provided inside the drying box 1. The stirring assembly includes a drive motor 9 fixedly mounted on the top of the drying box 1. The output shaft of the drive motor 9 passes through the drying box 1 and extends to the inner cavity of the drying box 1 where a rotating rod 10 is fixedly mounted. A stirring rod 11 is fixedly mounted on the surface of the rotating rod 10.

[0024] By setting up the stirring component, the uniformity of heating of chemical products can be improved when heating and drying chemical products. When the chemical products are drying, the user can drive the rotating rod 10 to rotate by the driving motor 9, and then drive the stirring rod 11 to rotate, so as to stir the chemical products in the drying box 1 to improve its heating uniformity.

[0025] A support plate 12 is fixedly mounted within the interior of the drying box 1. The bottom end of the rotating rod 10 is pivotally connected to the top of the support plate 12. Several groups of ventilation holes 13 are formed on the surface of the support plate 12. The support plate 12 provides auxiliary support for the rotating rod 10, enhancing its rotational stability. It also supports the chemical products, preventing them from coming into contact with the fan 2. The ventilation holes 13 ensure good air circulation within the drying box 1.

[0026] It is worth noting that a waste heat recovery component for recovering waste heat from water vapor generated by drying chemical products is fixedly installed in the inner cavity of the fixed cylinder 4 and below the heating wire 5. One end of the waste heat recovery component is connected to one side of the drying box 1. The waste heat recovery component includes a heat exchange tube 6 fixedly installed in the inner cavity of the fixed cylinder 4. The heat exchange tube 6 is arranged in a spiral shape, and one end of the heat exchange tube 6 passes through the fixed cylinder 4 and extends to the outside of the fixed cylinder 4 and is fixedly connected to a connecting tube 7. The end of the connecting tube 7 away from the heat exchange tube 6 is connected to the surface of the drying box 1.

[0027] Through the setting of the waste heat recovery component, the water vapor generated during the drying process of the chemical products will be output to the heat exchange tube 6 through the connecting tube 7 under high pressure. The air drawn from the outside by the fan 2 will first pass through the heat exchange tube 6. At this time, the hot water vapor in the heat exchange tube 6 will transfer heat to the air to preheat the air, thereby reducing energy consumption during the subsequent heating process of the heating wire 5. In this embodiment, the heat exchange tube 6 is arranged in a curved spiral shape, which can expand the area in contact with the air and thus improve the heat exchange effect. In addition, the heat exchange tube 6 in this embodiment is arranged in a funnel shape as a whole. After the waste heat recovery is completed, the water vapor can be discharged to the outside from the bottom end of the heat exchange tube 6.

[0028] Furthermore, a positioning bracket 8 is fixedly installed on the surface of the connecting pipe 7, and one side of the positioning bracket 8 is fixedly connected to the surface of the drying box 1. Through the setting of the positioning bracket 8, the connecting pipe 7 can be installed and fixed on one side of the drying box 1 to assist in positioning the installation position of the connecting pipe 7.
