Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a sampler for chlorinated polyethylene chlorination reaction products. Background Art
[0002] Chlorinated polyethylene is a saturated polymer material with the appearance of white powder, non-toxic and tasteless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and coloring properties. It has good toughness (still flexible at -30℃), good compatibility with other polymer materials, and a high decomposition temperature.
[0003] As disclosed in the authorization announcement number CN 216978462 U, a sampler for chlorinated polyethylene chlorination reaction products is disclosed, including a column, a feeding assembly and a storage assembly, the feeding assembly is arranged on the outer wall of the column, the storage assembly is arranged in the inner cavity of the column, the storage assembly includes a plurality of storage columns and a connecting rod, the plurality of storage columns are arranged in the inner cavity of the column, the connecting rod is connected to the plurality of storage columns, the bottom end of the connecting rod is connected to the bottom end of the inner cavity of the column, the top end of the connecting rod passes through the top end of the column and extends to the outside, the storage column is arranged in a cavity, and the edge of the storage column is arranged as a bevel. The utility model utilizes a setting mode that cooperates with a plurality of material storage columns and a connecting rod, so that the plurality of material storage columns rotate in the inner cavity of the column body by rotating the connecting rod. After sampling, the connecting rod is rotated to make the outer wall of the material storage column block the feed port, thereby preventing the taken sample from falling during the taking process, avoiding re-sampling due to the loss of the sample, and thus effectively improving the overall work efficiency. However, it does not solve the problem of sampling at a certain depth, nor does it solve the problem of raw materials falling after the sample is taken out: for this reason, we propose a sampler for chlorination reaction products of chlorinated polyethylene.

[0023] In the present embodiment, preferably, the extension mechanism includes an extension tube 204, a first feed port 200, a second feed port 201, a closing cover 202, and a third feed port 203. The first feed port 200 is opened on one side of the operating tube 100, and the extension tube 204 is threadedly arranged on one side of the first feed port 200. The connection between the extension tube 204 and the first feed port 200 of the operating tube 100 is in a closed state. The second feed port 201 is opened on one side of the extension tube 204 where it is attached to the first feed port 200, and a closing cover 202 is fixedly arranged on the side of the extension tube 204 that is attached to the first feed port 200.
[0024] In this embodiment, preferably, the cross-sectional area of the closing cover 202 is consistent with the cross-sectional area of the inner wall of the first feed inlet 200 , and the surface of the closing cover 202 can be snap-fitted and connected with the inner wall surface of the first feed inlet 200 .
[0025] In this embodiment, preferably, the inner wall cavity of the first feed port 200 is provided with a plurality of third feed ports 203, and the third feed ports 203 penetrate the inner wall cavity of the first feed port 200 and are connected to the inner wall space of the operating tube 100. The third feed ports 203 can be fixed by the threaded connection between the operating tube 100 and the extension tube 204 so that the closing cover 202 is pushed into the inner wall of the first feed port 200 to open the third feed ports 203.
[0026] In this embodiment, preferably, the sampling mechanism includes a closing piece 300, a pulling rod 301, a fourth feed port 302, and a sampling tube 303. A closing piece 300 is movably provided on one side of the inner wall of the operating tube 100, and the surface of the closing piece 300 fits the inner wall of the operating tube 100. A pulling rod 301 is fixedly provided at the center of one side of the closing piece 300, and the pulling rod penetrates the operating tube 100 and is fixed.

The material port 203 is closed by the closing cover 202, so that a negative pressure space is formed again in the operating tube 100 after sampling, which is convenient for the staff to sample from a certain depth. By pulling the pull rod 301 again in the operating tube 100 after the whole sampling, the closing piece 300 is moved, so that the chlorination reaction product of chlorinated polyethylene in the operating tube 100 enters the vertical sampling tube 303 through the fourth feed port 302. Since the sampling tube 303 is not arranged in parallel, but one side of the opening is vertical, it is convenient for the staff to perform individual sampling and ensure that the chlorination reaction product of chlorinated polyethylene will not fall during the individual sampling process.
