Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a box-type drying machine. Background Art

[0002] There are several modes of dryers, such as belt drying, drum drying, box drying, tower drying, etc. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air flow and radiation processes. Hot air drum drying is a process in which the hot air flow moves from the tail to the front, fully contacts the materials, and fully utilizes the heat transfer through heat conduction, convection, and radiation. The heat energy is directly transferred to the materials, so that the moisture of the materials is continuously evaporated in the drum. The induced draft device at the inlet draws out a large amount of moisture and wet air flow to prevent secondary pollution caused by dust discharge. The material movement is promoted through internal spiral stirring, sweeping, and copying to complete the entire drying process. Countercurrent conduction dehumidification avoids reducing repeated drying procedures.

[0003] When the existing dryer is in use, if there is outside air in the drying chamber, it will cause heat loss in the dryer, resulting in a waste of resources. If a sealed drying method is adopted, the humidity generated by the internal drying is relatively large, which increases the workload of the dehumidifier and easily causes a poor drying effect.

[0020] Furthermore, the air inlet end of the dehumidifier 13 is arranged at the air outlet 14 of the drying chamber, and the air outlet end of the dehumidifier 13 is arranged at the top.

[0021] Furthermore, the operation panel 17 is electrically connected to the dehumidifier 13 and the turbofan group 9 .

[0022] Furthermore, a temperature sensor, a humidity sensor and a pressure sensor are provided in the drying chamber 2 and are all electrically connected to the operation panel 17 .

[0023] Furthermore, a plurality of electric push rods 7 are electrically connected to the operation panel 17 .

[0024] Furthermore, the air inlet direction of the turbofan group 9 is in the direction of the second filter 10 and the first filter 8 , and the air outlet direction of the turbofan group 9 is in the direction of the drying chamber air inlet 11 .

[0026] Furthermore, a sealing structure is provided at the contact point between the door panel 15 and the dryer 1 .

[0027] Embodiment: When the device is in use, it is divided into two modes: internal circulation drying and external circulation drying.

[0028] When using external circulation drying, the baffle 4 is lifted by controlling several electric push rods 7 through the operation panel 17. When the baffle 4 is out of contact with the sealing strip 6, the gap between the baffle 4 and the sealing strip 6 forms an air inlet 5. When the turbofan group 9 is started, air will be taken in from the top and bottom at the same time and pumped into the drying chamber 2, and then enter the dehumidifier 13 through the drying chamber outlet 14 for dehumidification and then sent to the electric heating module 12 for heating. The heated air is again sucked in by the turbofan group 9 and pumped into the drying chamber 2 to complete the cycle. The advantage of external circulation is that when the outside air is relatively dry, the dry air added to the drying air circulation can reduce the power usage of the dehumidifier 13 and extend its service life.

[0029] When using the internal circulation drying chamber, the electric push rod 7 is controlled by the operation panel 17 to lower the baffle 4 so that the bottom wall of the baffle 4 is in close contact with the sealing strip 6, and the air inlet 5 above the turbofan group 9 is closed, so that the turbofan group 9 can take in air from the direction of the electric heating module 12, and the air forms a circulation in the device. The benefit of internal circulation is that it can reduce the heat loss of the drying air and reduce the power consumption of the electric heating module 12.
