[0002] Chemical stainless steel liquid samplers are usually designed to collect liquid samples during the chemical production process. These samplers are usually constructed of stainless steel materials to ensure their corrosion resistance and long service life.

[0003] When the stainless steel sampler collects chemical liquids, after opening the bottom sampling port of the stainless steel sampler, the sampling port is opened, and then the sampler is slowly placed into the liquid sample to collect the "whole process" liquid sample. After collection, the bottom sampling port is closed so that the liquid already collected in the sampler can be separated from the chemical liquid, avoiding the detachment of the sampled liquid. After sampling, liquid residues will adhere to the outer wall of the sampler. If the outer wall of the sampler is not cleaned thoroughly during transfer, it is likely to cause harm to the staff, which is not conducive to the sampling work of chemical liquids by the staff. Content of the Utility Model

[0004] The utility model provides a liquid sampler for chemical engineering, which has the characteristics of solving the problem that liquid residues adhere to the outer wall of the sampler, which is likely to cause harm to the staff and is not conducive to the sampling work of chemical liquids by the staff.

[0005] The utility model provides the following technical solution: It includes a stainless steel sampling tube and a pull rod. A sealing head is provided at the bottom of the pull rod. A sampling port matching the sealing head is provided at the bottom of the stainless steel sampling tube. A sliding sleeve is slidably connected to the outer wall of the stainless steel sampling tube. A partition block is fixedly connected to the inner wall of the sliding sleeve. A fixing block is fixedly connected to the outer wall of the sliding sleeve. A rotating rod is rotatably connected to the fixing block. A connecting plate is rotatably connected to the bottom of the rotating rod. A sealing sleeve is fixedly connected to one end of the connecting plate. A limiting ring for limiting the sealing sleeve is fixedly connected to the outer wall of the sliding sleeve. A connecting groove matching the pull rod is provided in the inner wall of the sealing sleeve.

[0006] Wherein, a sliding hole is provided on the outer wall of the sliding sleeve, and a sliding rod is also connected to the sliding hole. The bottom end of the sliding rod is fixedly connected with a mounting plate, and a spring is fixedly connected between the mounting plate and the outer wall of the sliding sleeve.

[0007] Wherein, a lifting block is fixedly connected to the top end of the pull rod. Upper and lower limiting blocks for limiting the pull rod are fixedly connected to the inner wall of the stainless steel sampling tube. The inner wall of the partition block is in contact with the outer wall of the stainless steel sampling tube.

[0008] Wherein, a slider is fixedly connected to the connection part between the sealing sleeve and the limiting ring, and a limiting groove matching with the slider is formed in the inner wall of the limiting ring.

[0009] Wherein, the outer wall of the sealing sleeve matches the inner wall of the sliding sleeve, and a sealing ring for docking with the top of the sealing sleeve is fixedly connected to the inner wall of the sliding sleeve.

[0010] The beneficial effects of the utility model are as follows: The sliding sleeve slides on the outer wall of the stainless steel sampling tube and is supported by the partition block, so it will not directly contact the liquid residue attached to the outer wall of the stainless steel sampling tube. Then, the sealing sleeve is adjusted below the sliding sleeve by rotating the rotating rod, so that the connecting groove formed in the sealing sleeve can be connected to the sealing head at the bottom of the pull rod, enabling the sliding sleeve to wrap the chemical liquid attached to the outer wall of the stainless steel sampling tube, avoiding harm to the staff during transportation due to the failure to clean up the residual liquid.

[0017] Please refer to Figures 1 - 4, the present utility model provides the following technical solutions: It includes a stainless - steel sampling tube 1 and a pull rod 11, and is characterized in that: a sealing head 111 is provided at the bottom of the pull rod 11, a sampling port 13 matching the sealing head 111 is provided at the bottom of the stainless - steel sampling tube 1, a sliding sleeve 2 is slidably connected to the outer wall of the stainless - steel sampling tube 1, a partition block 21 is fixedly connected to the inner wall of the sliding sleeve 2, a fixed block 22 is fixedly connected to the outer wall of the sliding sleeve 2, a rotating rod 23 is rotatably connected to the fixed block 22, a connecting plate 24 is rotatably connected to the bottom of the rotating rod 23, a sealing sleeve 25 is fixedly connected to one end of the connecting plate 24, a limiting ring 26 for limiting the sealing sleeve 25 is fixedly connected to the outer wall of the sliding sleeve 2, and a connecting groove 251 matching the pull rod 11 is provided in the inner wall of the sealing sleeve 25.

[0018] In this embodiment: the stainless steel sampling tube 1 is used to sample chemical liquids. By rotating the pull rod 11 in the stainless steel sampling tube 1, the sealing head 111 at the bottom of the pull rod 11 can be separated from the sampling port 13, so that the bottom of the pull rod 11 is misaligned with the sampling port 13, and then the stainless steel sampling tube 1 is placed in the sample liquid. At this time, the liquid can enter the stainless steel sampling tube 1 through the sampling port 13. After sampling, the top of the pull rod 11 can be pushed to support the bottom of the pull rod 11 at the sampling port 13, and then the sealing head 111 is connected to the sampling port 13 by rotating, so that the sampling port 13 is closed, thereby sealing the sample liquid. When the stainless steel sampling tube 1 is placed in the chemical liquid for sampling, When sampling, the bottom of the stainless steel sampling tube 1 will come into contact with the liquid, and chemical liquid residue will be generated. At this time, the sliding sleeve 2 that can be connected by sliding through the outer wall of the stainless steel sampling tube 1 can be rotated when the sliding sleeve 2 is sampling in the stainless steel sampling tube 1. The rotating rod 23 that is rotatably connected on the fixed block 22 can be rotated to make the sealing sleeve 25 installed on the bottom of the rotating rod 23 through the connecting plate 24 rotate to the outside of the bottom of the stainless steel sampling tube 1, so that the sealing sleeve 25 and the stainless steel sampling tube 1 are misaligned, so that the sliding sleeve 2 can slide upward, and the sealing sleeve 25 and the sliding sleeve 2 can slide to the top position of the stainless steel sampling tube 1 together, so that after the bottom of the stainless steel sampling tube 1 is immersed in the chemical liquid, the sliding sleeve 2 can be effectively prevented from contacting the liquid. After the steel sampling tube 1 is taken out from the chemical liquid, it can be attached to the chemical liquid through the sliding sleeve 2. At this time, the sliding sleeve 2 can be slid down so that the bottom of the sliding sleeve 2 slides down to the position below the stainless steel sampling tube 1. The sliding sleeve 2 and the stainless steel sampling tube 1 are supported by the partition block 21. At the same time, the partition block 21 at the bottom has a certain distance from the bottom of the sliding sleeve 2, so that the inner and outer walls of the bottom position of the sliding sleeve 2 can avoid contact with the liquid outside the stainless steel sampling tube 1. At this time, the rotating rod 23 is rotated to rotate on the fixed block 22. When it rotates, it can drive the connecting plate 24 fixed to the bottom end of the rotating rod 23 to rotate, so that the sealing sleeve 25 rotates on the inner wall of the limit ring 26. It can be rotated to the bottom of the stainless steel sampling tube 1, so that the sealing sleeve 25 can be received at the bottom of the sliding sleeve 2 and the bottom of the sliding sleeve 2 is sealed. At this time, the sealing sleeve 25 is below the bottom of the stainless steel sampling tube 1. At this time, the sliding sleeve 2 can be slid upward to make the connection groove 251 on the inner wall of the sealing sleeve 25 connected with the position of the sampling port 13, so that the pull rod 11 is rotated again, and the sealing head 111 is rotated into the sampling port 13. At the same time, the bottom is rotated into the connecting groove 251 to fix the position of the sealing sleeve 25, so that the sliding sleeve 2 can wrap the chemical liquid attached to the outer wall of the stainless steel sampling tube 1 to avoid the residual liquid from being not cleaned up and causing harm to the staff during its transportation.

[0019] The outer wall of the sliding sleeve 2 is provided with a sliding hole 3. A sliding rod 31 is also connected to the sliding hole 3. The bottom end of the sliding rod 31 is fixedly connected to a mounting plate 32. A spring 33 is fixedly connected between the mounting plate 32 and the outer wall of the sliding sleeve 2. The sliding hole 3 provided on the outer wall of the sliding sleeve 2 is used for installing the sliding rod 31. The mounting plate 32 fixedly connected to the bottom end of the sliding rod 31 is pulled by the spring 33, enabling the sliding rod 31 to support on the top of the stainless steel sampling tube 1, preventing the sliding sleeve 2 from sliding down and being attached by the liquid when the bottom of the stainless steel sampling tube 1 is inserted into the liquid, thereby ensuring the wrapping and protection of the sliding sleeve 2 for the stainless steel sampling tube 1.

[0020] The top end of the pull rod 11 is fixedly connected to a lifting block 112. Upper limit blocks 12 and lower limit blocks 121 for limiting the pull rod 11 are fixedly connected to the inner wall of the stainless steel sampling tube 1. The inner wall of the partition block 21 is in fit with the outer wall of the stainless steel sampling tube 1. The lifting block 112 fixedly connected to the top end of the pull rod 11 is used to facilitate the rotation and up-and-down pushing of the pull rod 11. The upper limit blocks 12 and lower limit blocks 121 are used to limit the pull rod 11, ensuring that the pull rod 11 slides up and down at the center of the stainless steel sampling tube 1. The inner wall of the partition block 21 is in fit with the stainless steel sampling tube 1, ensuring the tight connection between the sliding sleeve 2 and the stainless steel sampling tube 1.

[0021] A slider 252 is fixedly connected to the connection between the sealing sleeve 25 and the limit ring 26. A limit groove 261 matching the slider 252 is provided on the inner wall of the limit ring 26. The slider 252 fixedly connected to the connection between the sealing sleeve 25 and the limit ring 26 is used to be limited in the limit groove 261 provided on the inner wall of the limit ring 26, ensuring the horizontal rotation of the sealing sleeve 25, enabling it to ensure butt-joint with the bottom of the sliding sleeve 2 and seal the stainless steel sampling tube 1.

[0022] The outer wall of the sealing sleeve 25 matches the inner wall of the sliding sleeve 2. A sealing ring 27 for butt-jointing with the top of the sealing sleeve 25 is fixedly connected to the inner wall of the sliding sleeve 2. The outer wall of the sealing sleeve 25 matches the inner wall of the sliding sleeve 2. After the sealing ring 27 fixedly connected to the inner wall of the sliding sleeve 2 reaches the bottom of the sliding sleeve 2, it can be connected to the top of the sealing sleeve 25 to ensure its sealing performance.

[0023] The working principle and use process of the utility model are as follows: the pull rod 11 is separated from the sampling port 13, so that the bottom of the stainless steel sampling tube 1 is placed in the chemical liquid, and the liquid can enter the stainless steel sampling tube 1 through the sampling port 13. The pull rod 11 is then used to seal the sampling port 13, so that the stainless steel sampling tube 1 is taken out from the liquid. At this time, the sliding sleeve 2 can be lowered to the position below the stainless steel sampling tube 1 by sliding the sliding sleeve 2 downward, and then the rotating rod 23 is rotated so that the sealing sleeve 25 can be received at the bottom of the sliding sleeve 2 to seal the bottom of the sliding sleeve 2. At this time, the sealing sleeve 25 can be sealed at the bottom of the sliding sleeve 2. The sealing sleeve 25 is located below the bottom of the stainless steel sampling tube 1. At this time, the sliding sleeve 2 can be slid upward to connect the connecting groove 251 on the inner wall of the sealing sleeve 25 with the position of the sampling port 13, so that the pull rod 11 is rotated again, and the sealing head 111 is rotated into the sampling port 13. At the same time, the bottom is rotated into the connecting groove 251 to fix the position of the sealing sleeve 25, so that the sliding sleeve 2 can wrap the chemical liquid attached to the outer wall of the stainless steel sampling tube 1, avoiding the residual liquid that is not cleaned up and causing harm to the staff during its transportation.
