The beneficial effects of the utility model are as follows: in actual use, the outer shell and the inner shell are firstly inserted into the activated carbon bag, and the outer shell is rotated so that the outer shell and the inner shell form a sampling cavity, and at the moment, the sealing piston is ensured to be positioned outside the sampling cavity. When a sample is required to be taken, the sampling rod is pulled and the sealing piston is driven to move into the sampling cavity, at the moment, the sealing piston can extrude materials in the sampling cavity, and part of powdered activated carbon materials are discharged through the discharge hole, so that sampling is realized. In the whole process, the powder activated carbon is discharged only through the discharge port, so that the defect that the powder activated carbon particles float in the air to cause environmental pollution is avoided. The utility model is especially suitable for sampling operation of materials with hidden health hazards of human bodies, which are represented by powder activated carbon particles.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The powder activated carbon sampling device as shown in fig. 1, 2, 3 and 4 comprises an outer shell 3 and an inner shell 2, wherein the outer shell 3 and the inner shell 2 are cylindrical shell structures with notches on the side walls, the inner shell 2 is rotatably sleeved in the outer shell 3, the outer shell 3 and the inner shell 2 form a sampling cavity, sampling sealing devices are arranged in the inner shell 2 and the outer shell 3, each sampling sealing device comprises a sampling rod 11 and a sealing piston 12 arranged at one end of the sampling rod 11, the sampling rod 11 is slidably arranged on the end face of one end of the outer shell 3, and a discharge hole 31 is formed in the side wall of the outer shell 3; when the sealing piston 12 slides with the sampling rod 11 into the outer shell 3 and the inner shell 2, the powdered activated carbon in the sampling chamber is pressed by the sealing piston 12 and discharged from the discharge port 31. The scheme has the following advantages: 1. the floating amount of the carbon powder is reduced, and the amount of the carbon powder sucked by a sampling operator is reduced; 2. the pollution degree of the sampling environment is reduced; 3. time is saved compared with the previous sampling mode; 4. the device is simple, and powder is prevented from being remained in the inner shell after each sampling.

In order to facilitate the driving of the sampling rod 11, the following scheme may be selected: the other end head of the sampling rod 11 is provided with a driving handle 1, and the driving handle 1 is arranged outside the outer shell 3 and the inner shell 2. In practical arrangements, it is preferred that the sampling rod 11 is arranged coaxially with the outer housing 3 and the inner housing 2. The direction of extension of the outlet opening 31 is preferably perpendicular to the housing 3.

As shown in fig. 1 and 2, the device mainly consists of two incomplete cylindrical shells, an inner shell 2 and an outer shell 3, and the radian of the circumference corresponding to the notch of each of the inner shell 2 and the outer shell 3 is 140 degrees. The larger the gap is, the easier the carbon powder enters the inside of the shell. The inner and outer shells can rotate relatively, as shown in fig. 3 and 4, a sampling cavity is formed by the relative rotation of the inner shell 2 and the outer shell 3, and carbon powder is enclosed. Generally, the length of the inner and outer shells is designed to be 40cm, the diameter is 4cm, and the theoretical single sampling volume is about 500 ml. The inner shell 2 and the outer shell 3 can be made of 304 stainless steel, the material of the sealing piston 12 does not affect the activated carbon, the surface roughness Ra1.6 of the inner shell 2 ensures that the friction force is small when the piston is pushed and pulled, the diameter of the piston is slightly larger than that of the inner shell, and the carbon powder is not leaked.

When inserting the device into an activated carbon bag for sampling, first, the space between the inner shell 2 and the outer shell 3 is shown in fig. 3. The housing 3 is turned to the state shown in fig. 4 as after the insertion of the toner bag. In addition to being trapped in the sampling chamber during the rotation described above, powdered activated carbon may also enter the interior of the device through the activated carbon flow direction 4 shown in fig. 1. Then, the sealing piston 12 is pumped into the sampling cavity, so that the powdered activated carbon can be extruded out of the discharge hole 31, and a sampling operation is completed.
