This utility model relates to a device for treating volatile organic compounds (VOCs), belonging to the field of compound treatment. It includes a working chamber with an inlet pipe and an outlet pipe fixedly connected to its left and right sides, respectively. Multiple activated carbon adsorption plates are movably inserted into the inside of the working chamber, and a filter screen is movably inserted into the inside of the inlet pipe. Two insert blocks are slidably connected to the inside of the inlet pipe, and two slots adapted to the insert blocks are formed on the inside of the filter screen. The outer sides of the two insert blocks are movably inserted into the corresponding slots. A threaded block is threadedly connected to the outside of the inlet pipe, and the inner side of the threaded block movably abuts against the outer side of the two insert blocks. This device for treating VOCs, through the cooperation of the insert blocks, small blocks, and threaded blocks, allows the filter screen to be easily fixed to the device, facilitating quick disassembly by the user. This avoids the problem of bolts becoming rusted or aged and difficult to remove when disassembling bolt-fixed filters.

The application discloses an automatic pipe storage method and device, and relates to the technical field of oil and gas exploitation supporting equipment. The automatic pipe storage method comprises the following steps: step 1, two storage racks are horizontally moved to a working position with a certain distance; step 2, the storage racks are rotated so that the continuous feeding storage mechanisms on the two storage racks are turned to the inner side and oppositely arranged; step 3, a manipulator carries a pipe column to the continuous feeding storage mechanism; step 4, the continuous feeding storage mechanism transports the pipe column from one side of the storage rack to the other side; step 5, steps 3 and 4 are repeated until the pipe column is placed or the oil pipe is fully placed in the pipe storage mechanism; and step 6, after the oil pipes on the pipe storage mechanism are all removed, the storage racks are rotated to be parallel to the bottom frame, and the distance between the two is reset to the storage position. The application is convenient for storage and transportation of pipe columns with different sizes, and the cooperation of the carrying manipulator and the continuous feeding storage mechanism improves the continuity and operation efficiency of the automatic pipe storage operation.

This utility model discloses an RF connector testing device, including a base box. The base box contains a pushing mechanism for movement testing, and the top of the base box contains a reset mechanism for pressure testing. This utility model, through the coordinated arrangement of the pushing and reset mechanisms, achieves the advantage of rapid detection of the RF connector's length, improving testing efficiency, simplifying operation, and facilitating material handling. The pushing mechanism allows for direct pushing to move the connector, thus working in conjunction with the reset mechanism to perform length testing.
