Description

Technical Field

[0001] This utility model relates to the field of ethylene glycol production technology, specifically to a sampling device for ethylene glycol production. Background Technology

[0002] Ethylene glycol, also known as glycol or 1,2-ethylene glycol, abbreviated as EG, has the chemical formula (CH₂OH)₂ and is the simplest diol. It is a colorless, odorless, sweet-tasting liquid, toxic to animals, with a lethal dose for humans of approximately 1.6 g / kg. Ethylene glycol is miscible with water and acetone, but its solubility in ethers is relatively low.

[0003] During the production of ethylene glycol, sampling devices are required to sample the ethylene glycol. However, existing sampling devices generally do not have a positioning mechanism and require manual sampling. Manual sampling cannot accurately measure the quantity of samples, which affects the sampling results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sampling device for ethylene glycol production.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A sampling device for ethylene glycol production includes a positioning frame, a plurality of anti-slip pads at the bottom of the positioning frame, a sampling tube at the top of the positioning frame, a suction tube at one end of the sampling tube, a piston plate embedded inside the sampling tube, a piston rod fixedly connected to one side of the piston plate, one end of the piston rod extending through to the outside of the other side of the sampling tube, and a control mechanism on the outside of the sampling tube.

[0007] The sampling tube is provided with a positioning mechanism on the other side. The positioning mechanism is used to fix the position of the piston rod. The positioning mechanism includes two positioning jaws. Each of the two positioning jaws is provided with a connecting circular plate on its top. Each of the connecting circular plates is provided with a connecting plate on its top.

[0008] Preferably, a lever is fixedly connected to the top of each of the two connecting plates, and a first spring is provided between the two levers.

[0009] Preferably, the positioning mechanism further includes two connecting shafts, which are located on the other side of the sampling tube and are movably connected to the sampling tube via bearings. The connecting shafts are embedded inside the connecting circular plate.

[0010] Preferably, the piston rod has multiple locking grooves at its top, which match the positioning grippers.

[0011] Preferably, the control mechanism includes a movable plate, which is disposed at the top of the sampling tube. A limiting rod is provided at the top of the sampling tube, and the limiting rod is embedded inside the movable plate and slides with the movable plate.

[0012] Preferably, each of the two positioning grippers has a pad on its outer side, and each of the two pads has a second spring on its outer side. The other side of the sampling tube has a side plate, and the side plate is fixedly connected to the second spring.

[0013] Preferably, the movable plate is provided with connecting rings on both sides, and the bottom ends of the two connecting rings are fixedly connected with sliders.

[0014] Preferably, the positioning frame is fixedly connected to limit rails on both sides, and the two sliders are respectively embedded in the two limit rails and slide in relation to the limit rails.

[0015] Preferably, each of the two sliders has a movable block on its outer side, and each of the two movable blocks has a stop bar on one side.

[0016] Preferably, one end of each of the two stop rods is provided with a movable frame, and a push plate is fixedly provided on one side of the movable frame, the push plate being fixedly connected to the piston rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By having the user pull the movable plate, the control mechanism operates to control the piston rod. When the piston rod moves out, the user can operate the positioning mechanism to position the piston rod, making the range of piston rod movement more precise and thus the sampling amount more accurate. This invention greatly improves the efficiency of ethylene glycol sampling. At the same time, the device adopts a positioning gripper and locking groove structure design, which allows the movable rod to be stably positioned, making the structure more compact. In addition, the device adopts a first spring and second spring structure design, which allows the positioning mechanism to rebound and position stably, making the structure more stable.
