DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 2, the present utility model provides a technical solution: a drying device provided with a circulating heating mechanism, including a cabinet body 1 and a heating mechanism. A drying chamber 2 is provided inside the cabinet body 1, and a recovery part 3 is provided at the top of the cabinet body 1;

[0021] One side of the cabinet body 1 is connected to a heating box 4. The heating mechanism includes a heating chamber 5, a heating wire 6 and a diversion plate 7. The heating chamber 5 is provided inside the heating box 4, and both the heating wire 6 and the diversion plate 7 are provided on the inner wall of the heating chamber 5. The diversion plate 7 is arranged obliquely upward;

[0022] The inner wall of the drying chamber 2 is provided with a dispersion pipe 8. One side of the dispersion pipe 8 is provided with a plurality of air outlets 9, and the size of the air outlets 9 increases sequentially along the axial direction of the dispersion pipe 8.

[0023] The material to be dried is placed in the drying chamber 2 for drying. The heating wire 6 heats the air. The heated air enters the dispersion pipe 8 and then is discharged into the drying chamber 2 through the air outlets 9 opened on the dispersion pipe 8. The size of the air outlets 9 at the position farther away from the heating chamber 5 on the dispersion pipe 8 is larger, so that the air outlets 9 at a long distance can discharge more hot air to offset the temperature drop caused by the long distance, thereby improving the uniformity of the overall temperature in the drying chamber 2. The diversion plate 7 is arranged towards the air inlet end. After the air enters, it is blocked by the diversion plate 7, and the flow rate is slowed down, so that the air can contact the heating wire 6 more fully. The air passing through the drying chamber 2 is collected by the recovery part 3 at the top, and then sent back to the heating chamber 5 for heating and then conveyed to the dispersion pipe 8. A suction fan is provided at the top of the drying chamber 2 to send the air in the drying chamber 2 into the recovery part 3, and due to the formation of negative pressure, the hot air in the heating chamber 5 can be drawn into the drying chamber 2 from the dispersion pipe 8, forming the air flow direction.

[0024] In this embodiment, as a preferred solution, an air inlet pipe 10 and an exhaust pipe 11 are respectively provided at the top and bottom of the heating box 4. Both the air inlet pipe 10 and the exhaust pipe 11 are communicated with the inside of the heating chamber 5. One end of the air inlet pipe 10 is communicated with the inside of the recovery part 3, and one end of the exhaust pipe 11 is communicated with one end of the dispersion pipe 8 for conveying hot air. The inner wall of the heating box 4 is provided with a heat insulation layer 12 for isolating the temperature in the heating chamber 5.

[0025] The heat insulation layer 12 separates the heating chamber 5 from the outer wall of the heating box 4 to prevent the operator from being scalded when contacting the heating box 4. At the same time, it also reduces the heat dissipation and improves the energy utilization rate. The heated air is conveyed to the dispersion pipe 8 along the bottom exhaust pipe 11, enters the drying chamber 2 through the dispersion pipe 8 to dry the material. The air after drying ends will enter the recovery part 3 at the top, and then enter the heating chamber 5 along the air inlet pipe 10 for circulating heating, and then enter the drying chamber 2 again for drying after heating, improving the drying efficiency while reducing the temperature fluctuation.

[0026] In this embodiment, as a preferred solution, a mounting block 13 is fixedly connected to the inner wall of the drying chamber 2, a placement plate 14 is detachably connected to the surface of the mounting block 13, a protective door 15 is hingedly connected to the front of the cabinet 1, and an observation hole is provided on the surface of the protective door 15.

[0027] There are multiple mounting blocks 13, and the position of the placement plate 14 can be selectively installed according to the height of the material to improve flexibility during use. Sealing pads are provided around the protective door 15. After closing the protective door 15, the drying chamber 2 can be sealed to reduce the leakage of hot air and improve utilization.

[0028] In this embodiment, as a preferred solution, a filter plate 16 is inserted into one side of the recovery part 3 to collect dust.

[0029] The dust generated during the drying process will be sucked away by the exhaust fan in the drying chamber 2 and transported to the recovery part 3 by the exhaust fan. At this time, the mixed dust will be blocked by the filter plate 16 in the recovery part 3 to prevent it from continuing to participate in the circulation, thereby reducing the pollution to the material. The filter plate 16 can be pulled out and replaced for easy maintenance in the future.

[0030] In the utility model, the working steps of the device are as follows:

[0031] 1. Open the protective door 15, and selectively fix the placement plate 14 on the mounting block 13 according to the size of the material to be dried, and close the protective door 15 after placing the material;

[0032] 2. Start the internal exhaust fan and heating wire 6 to heat the air and drive the air flow to dry the materials in the drying chamber 2;

[0033] 3. After drying, open the protective door 15 to take out the material;

[0034] 4. After using for a period of time, pull out the filter plate 16, clean the filter plate 16 and then install it back.

[0035] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
