DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, an atmosphere drying device is provided, the atmosphere drying device comprises a drying chamber 4 and a cooling chamber 11 arranged on a base 8, the drying chamber 4 and the cooling chamber 11 are closed spaces, and are connected to each other, separated by a lifting door 1 in the middle, and a transmission device 13 (such as Figure 3 The drying chamber 4 and the cooling chamber 11 are both provided with an atmosphere control system, which includes an outlet valve 2, an inlet valve 3 and a flow controller 5, for providing ambient gas to different chambers and controlling the gas flow; a heating device is provided in the drying chamber for heating, and is controlled by an external drying chamber controller 6, etc. The transmission device is controlled by an external transmission controller 9. The drying chamber 4 and the cooling chamber 11 are both provided with a chamber door, which is opened and closed by a chamber door switch 12.

[0021] In the absence of a cooling chamber, the material is dried at high temperature in the drying chamber 4, and the drying chamber 4 is evacuated or inert gas or special gas is input for protection. After the high-temperature drying is completed, the material cannot be taken out of the drying chamber 4 and cooled in the natural environment immediately, but needs to be placed in the atmosphere for cooling. Generally, the material is kept in the drying chamber 4 and cooled as the temperature of the drying chamber 4 decreases. In this case, if there are other materials to be dried later, it is necessary to wait for the drying chamber to cool down, take out the cooled materials, and then re-place new materials and heat them again. Not only is the waiting time for cooling long, but reheating the drying chamber also consumes energy, which is neither energy-saving nor efficient.

[0022] The utility model sets a cooling chamber 11 on one side of the drying chamber 4, and the middle is separated by a lifting door 1. When the lifting door 1 is lowered, each chamber is sealed and works independently, and when the lifting door 1 is raised, materials between adjacent chambers can be transferred to each other.

[0023] Before using the whole device, first confirm the connection status of the air inlet valve 3 and the air outlet valve 2 in combination with the air source, open the door through the gate valve 12 to add the material to the drying bin 4, set the drying parameters through the drying bin controller 6 and the flow meter 5 to complete the drying, and observe the situation in the bin through the observation window 7 during the drying period; at the end of drying, adjust the environmental conditions of the cooling bin 11 such as atmosphere and temperature in advance through the cooling bin controller 10; after the environmental conditions of the cooling bin 11 meet the requirements, adjust the roller conveyor belt of the transmission components inside the lifting door 1 and the base 8 through the transmission controller 9 to transfer the material to the cooling bin 11 for cooling, and then close the lifting door 1, and the material transfer is completed; the drying bin 4 can carry out the drying operation of the next batch of materials; after the cooling of the materials is completed, open the door of the cooling bin 11 through the door switch 12 to take out the dried and cooled materials.

[0024] The atmosphere drying device provided by the utility model is that after the material is dried in the drying bin 4 under the set atmosphere and reaches the required conditions, it is quickly transferred to the cooling bin 11 with the same atmosphere conditions through the transmission device. The material is cooled in the cooling bin, and at the same time, other materials can be loaded into the drying bin 4 again for drying without cooling and heating. The internal environment of the drying device can be designed according to needs, including ambient gas filled with nitrogen, oxygen or helium or a vacuum state. The device realizes the rapid transfer of dry materials, thereby releasing the baking space to continue drying new materials, while realizing the rapid transfer of materials and improving the use efficiency of the equipment. The drying bin temperature range of the drying bin is 0 to 400°C.

[0025] like Figure 2 As shown, a second cooling bin 14 is provided on the other side of the first cooling bin 11. The first cooling bin 11 can be transferred to the subsequent cooling bins in sequence. The structure is the same as the first cooling bin 11, and the operation mode is similar to the transfer of the drying bin 4 to the first cooling bin 11, and the temperature is gradually reduced by controlling different gradient temperatures. In fact, according to different needs, more step-by-step cooling bins with different temperatures can be set on the right side of the second cooling bin 14 for cooling. The number of cooling bins in this patent is at least 1, and the number of cooling bins can be adjusted to match the cooling speed of the drying bin material to meet the needs of different temperatures or continuous cooling, so as to achieve the most economical and efficient purpose.

[0026] like Figure 3 Shown, the transmission device 13 at the bottom of different bins is a roller conveyor belt, which transmits materials from the last bin to the next bin after the lifting door is lifted. In fact, the roller conveyor belt is only an exemplary description, and can also be transmitted by a conveyor belt or other transmission structures.

[0027] In addition, the drying chamber controller 6 has an alarm function. If there is any abnormality in the process, such as deviation from parameter settings, abnormal operation or transmission, the alarm is activated. The alarm modes include buzzer and warning light.

[0028] The above examples are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
