[0027] It should be noted that the VOC exhaust pipeline is connected with the threaded quick connector A head 4, the threaded quick connector B head 5 is connected with the pipeline of the subsequent treatment equipment, the sealing B cover 31 is covered on the threaded ball dropping pipe 3, and the abutting rod 311 is abutted at the elbow of the threaded ball dropping pipe 3.
