[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 The utility model provides a chemical reactor material sampler, comprising a reactor 1, a collection port 2 and a sampling device 3. The top of the reactor 1 is provided with the collection port 2, and the sampling device 3 is installed inside the collection port 2.

[0023] See also Figure 2-5The sampling device 3 in the utility model includes a sleeve 31, a flange 32, a sampling tube 33, a feed pipe 34, a limit slider 35, a slide rail 36, a threaded section 37 and an adjusting rotary sleeve 38. The sleeve 31 straightly passes through the collection port 2 and extends into the inner side of the reactor 1. The outer surface of the sleeve 31 is sleeved with a flange 32, and the flange 32 is flange-connected with the top of the collection port 2 to realize the installation connection between the sampling device 3 and the collection port 2. The sampling tube 33 is movably arranged inside the sleeve 31, and the bottom end of the sampling tube 33 passes through the sleeve 31 and extends into the inner side of the reactor 1. The feed pipe 34 is connected to the top opening of the sampling tube 33. The sampling tube 33 and the feed pipe 34 are connected to each other. A limit slider 35 is welded on the outer surface of the middle section of the sleeve 31, and a slide rail 36 is longitudinally provided on the inner wall of the sleeve 31. The limit slider 35 can slide straightly along the inner side of the slide rail 36, so that the sampling tube 33 and the sleeve 31 are slidably connected. The portion of the upper half of the sampling tube 33 provided with an external thread is a threaded section 37. The top of the sleeve 31 is rotatably connected with an adjusting rotary sleeve 38 through a bearing seat. The axial directions of the sleeve 31 and the adjusting rotary sleeve 38 are in the same linear direction. The adjusting rotary sleeve 38 is sleeved on the surface of the threaded section 37 and is threadedly connected thereto. When the adjusting rotary sleeve 38 rotates, it can cooperate with the threaded section 37, thereby pushing the sampling tube 33 to telescopically slide in the sleeve 31, thereby realizing the height adjustment of the sampling tube 33.

[0024] To further illustrate, the vertical length of the threaded section 37 is not less than 1 / 2 of the vertical length of the reactor 1, so that the sampling tube 33 has sufficient height adjustment margin to collect samples at different depths.

[0025] To further explain, the limiting slider 35 is located below the threaded section 37 . Under the limiting action of the limiting slider 35 , the threaded section 37 cannot pass through the sleeve 31 and extend into the inside of the reactor 1 , thereby preventing the surface of the threaded section 37 from being contaminated by materials.

[0026] To further explain, a rubber ring 39 is installed at the opening of the bottom end of the sleeve 31, and the rubber ring 39 is tightly fitted on the outer surface of the sampling tube 33. The rubber ring 39 is used to scrape off the material adhering to the outer surface of the sampling tube 33 to prevent the material from entering the sleeve 31.

[0027] Further, the outer surface of the threaded section 37 is provided with longitudinally arranged length values ​​310 , and the length value 310 exposed by the threaded section 37 outside the adjusting rotary sleeve 38 can help the staff to better judge the sampling depth of the sampling tube 33 in the reactor 1 .

[0028] To further explain, the material delivery pipe 34 is a flexible hose, so that the material delivery pipe 34 can be bent and deformed to adapt to the lifting and lowering action of the sampling tube 33.

[0029] Here’s how it works:

[0030] First, before use, the sampling device 3 needs to be assembled with the reactor 1. The specific operation method is: first, insert the sampling tube 33 together with the sleeve 31 into the collection port 2 until the flange 32 contacts the collection port 2, and then bolt the flange 32 to the collection port 2 to fix the sleeve 31 at the position of the collection port 2. The sampling tube 33 can pass through the sleeve 31 and extend into the reactor 1, thereby completing the assembly of the sampling device 3 and the reactor 1.

[0031] Second, when in use, first connect the feed pipe 34 to an external power pump to provide extraction power for the sampling device 3, so that the sampling pipe 33 extracts the material in the reactor 1, and then pumps the sample outward through the feed pipe 34, thereby completing the sampling operation. Sampling can be performed during the material reaction process to confirm the reaction state of the material.

[0032] Third, when it is necessary to collect samples at different depths in the reactor 1, the staff controls the adjusting rotary sleeve 38 to rotate. When the adjusting rotary sleeve 38 rotates forward, the threaded section 37 is pushed downward. At this time, the sampling tube 33 slides downward out of the sleeve 31 along the slide rail 36 through the limit slider 35, so that the sampling depth of the sampling tube 33 decreases. When the adjusting rotary sleeve 38 rotates reversely, the threaded section 37 is pushed upward. At this time, the sampling tube 33 slides upward into the sleeve 31, thereby increasing the sampling depth of the sampling tube 33. The height position of the sampling tube 33 is flexibly adjustable to collect samples at a certain depth and further expand its sampling range. In addition, by setting a length value 310 on the outer surface of the threaded section 37, the length value 310 of the threaded section 37 exposed outside the adjusting rotary sleeve 38 can help the staff better judge the sampling depth of the sampling tube 33 in the reactor 1, and the operation is more convenient.

[0033] Fourth, by sleeve-fitting the rubber ring 39 at the bottom opening of the sleeve 31 , when the sampling tube 33 telescopes in the sleeve 31 , the rubber ring 39 can scrape off the material adhering to the outer surface of the sampling tube 33 to prevent the material from entering the sleeve 31 .

[0034] The utility model provides a chemical reactor material sampler, wherein a sampling device 3 is arranged at the inner side of a collection port 2, and a staff member controls and adjusts a rotary sleeve 38 to rotate. When the rotary sleeve 38 is rotated in the forward direction, a threaded section 37 is pushed downward, and at this time, a sampling tube 33 slides downwardly out of a sleeve 31 along a slide rail 36 through a limit slider 35, so that the sampling depth of the sampling tube 33 is reduced. When the rotary sleeve 38 is rotated in the reverse direction, the threaded section 37 is pushed upward, and at this time, the sampling tube 33 slides upward into the sleeve 31, so that the sampling depth of the sampling tube 33 is increased. The height position of the sampling tube 33 is flexibly adjustable, so as to collect samples at a depth, and further expand its sampling range. A rubber sleeve 39 is installed and sleeved on the opening at the bottom end of the sleeve 31, and materials adhered to the outer surface of the sampling tube 33 are scraped off by the rubber sleeve 39 to prevent the materials from entering the sleeve 31.
