Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a urea sampler. Background Art
[0002] According to national standards, urea must be tested for relevant parameters before it leaves the factory. Therefore, samples must be taken regularly on site during the urea production process and brought back to the analysis room for analysis. Urea moisture is an important indicator for testing. In large-scale urea production enterprises, especially those using high-tower granulation, urea under the tower is a very representative sampling point.
[0003] In daily work, analysts will carry spoons and sealed bags to the belt at the bottom of the urea tower to take samples. Due to different habits of analysts in different units, they may carry different types of spoons or packaging bags, but they are basically the same.
[0004] However, in summer, conventional spoons are used for sampling. Due to seasonal factors, the humidity and temperature are high in summer, so the temperature of newly granulated urea will also be high (about 70 degrees). If the sample is sent to the package immediately after sampling, the heat cannot be dissipated, which has a great impact on the analysis results of moisture and particle strength indicators. The moisture test result of urea that has not been cooled is higher than that of urea after cooling, which causes errors in the judgment of urea grade.

[0040] Preferably, a gap is provided between the inner cylinder 212 and the outer cylinder 222, so as to reduce the friction force of the relative rotation between the inner cylinder 212 and the outer cylinder 222, and facilitate the rotation between the inner cylinder 212 and the outer cylinder 222.

[0041] The sealing layer 23 can be made of paper pads, asbestos pads, etc., which are attached to the inner wall of the cylinder to form a thick pad, or directly formed into a raised block structure by processing inside the cylinder wall, which is used to reduce the gap between the inner cylinder 212 and the outer cylinder 222 at the position of the sealing layer 23, thereby reducing air circulation and achieving a sealing effect.
[0042] It is worth pointing out that if the outer wall of the inner tube 212 and the inner wall of the outer tube 222 are set as smooth surfaces, no gap is required, and the inner tube 212 and the outer tube 222 are slidably connected.

[0044] The bottle cap 3 adopts a scissor-type opening and closing structure to prevent the flip cover structure from fanning up the urea during sampling, causing urea to be splashed and wasted. At the same time, by setting the bottle cap 3, the urea in the sampling bottle 2 can be ensured not to be spilled during the sampling process.
[0045] Specifically, the bottle cap 3 includes two cover bodies 31, and the two cover bodies 31 are symmetrically arranged at the bottle mouth of the sampling bottle 2.

[0047] The axis of the adjusting rod 36 is perpendicular to the axis of the sampling bottle 2 . The sampling rod 1 is provided with a fixing seat 37 . The fixing seat 37 is provided with a fixing hole. The adjusting rod 36 is arranged in the fixing hole, so as to ensure the stable position of the adjusting rod 36 .

[0051] During use, the operator pushes the adjustment rod 36 toward the sampling bottle 2 through the pushing block 40, thereby allowing the cover body 31 to rotate around the respective connecting shafts 32 to achieve an opening operation. When the pushing block 40 is not subjected to force, the elastic force of the return spring 39 will push the adjustment block 38 to move the adjustment rod 36 away from the sampling bottle 2, thereby allowing the cover body 31 to rotate around the respective connecting shafts 32 to achieve a closing operation.
