The device comprises a bearing device 1, wherein the bearing device 1 is provided with a sealed cavity 11, and a feeding hole 12 and a sampling hole 13 which are communicated with the sealed cavity 11 are arranged on the bearing device 1;
The sealing member 2 is arranged in the sealing cavity 11 and seals the sampling port 13;
A sampling container 3, wherein the open end of the sampling container 3 is provided with a connecting part 31 which is hermetically connected with the bearing device 1, and an opening piece 32 is arranged on the sampling container 3; when the sampling vessel 3 is sealingly connected to the receiving device 1, the opener 32 acts on the sealing member 2 to place the sampling vessel 3 in communication with the sealing chamber 11.
In the material sampling mechanism of the utility model, when the sampling container 3 is not connected with the bearing device 1 in a sealing way, the sealing element 2 seals the sampling port 13; when the sampling container 3 is connected with the bearing device 1 in a sealing way, the opening piece 32 acts on the sealing piece 2, so that the sampling container 3 is communicated with the sealing cavity 11; in the process of connecting and disassembling the sampling container 3 and the bearing device 1 of the material sampling mechanism, the bearing device 1 is not communicated with the outside, sealed sampling is realized, operation equipment in a closed-loop circulating spray dryer connected with the bearing device 1 does not need to be stopped, the sampling of materials cannot influence the capacity of the closed-loop circulating spray dryer, and the problem of gas leakage caused by sampling operation when the pressure in the closed-loop circulating spray dryer is high can be avoided.
The sealing element 2 is movably arranged at the sampling port 13; the opening member 32 is a push rod having a size smaller than the sampling port 13 of the receiving device 1. When the sampling container 3 is connected with the bearing device 1 in a sealing way, the push rod extends into the sealing cavity 11 from the sampling port 13, so that the sealing element 2 is pushed to move, the sealing element 2 is moved out from the sampling port 13, and the sampling container 3 is communicated with the sealing cavity 11; because the movement of the sealing element 2 is driven by the pushing force of the push rod, when the pushing force of the push rod does not act on the sealing element 2, the sealing element 2 can be reset to the sampling port 13 to seal the sampling port 13; the structure is simple and convenient to control.
