Description

Technical Field

[0001] This utility model relates to the field of ethanol sampling, and in particular to a sampling component for determining the impurity content in ethanol production. Background Technology

[0002] Ethanol is a volatile, colorless, and transparent liquid at room temperature and pressure. It has low toxicity, but the pure liquid is not suitable for direct consumption. An aqueous solution of ethanol has an alcoholic odor and a slightly pungent taste. Ethanol is flammable, and its vapor can form an explosive mixture with air. Ethanol is miscible with water in any proportion and is also miscible with chloroform, ether, methanol, acetone, and most other organic solvents.

[0003] In existing technologies, ethanol is mostly sampled by scooping the ethanol liquid with a spoon-shaped container and then pouring it into a sampling bottle for sampling. Some electric sampling mechanisms are handheld, requiring both hands to hold the sampling device and the sampling bottle respectively, which can easily lead to ethanol sample spillage during sampling.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a sampling component for determining the impurity content in ethanol production, in order to solve the aforementioned technical defects.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] The sampling component for determining the impurity content in ethanol production includes a substrate. A vertically mounted mounting frame 1 is provided above the substrate. A mounting plate 1 is fixedly mounted on one side of the mounting frame 1 by welding. A bracket is also fixedly mounted on one side of the mounting frame 1 by bolts. A mounting frame 2 is also fixedly mounted on one side of the mounting frame 1 by bolts. A sampling control mechanism is provided inside the mounting frame 1. The sampling control mechanism includes a stepper motor. A spur gear is fixedly mounted on the drive shaft of the stepper motor after passing through the mounting frame 1.

[0008] Preferably, the mounting bracket one is fixed to the base plate by bolts, and a mounting plate two is fixed to one end of the mounting bracket one by welding. A straight faucet is installed below the mounting plate two by bolts.

[0009] Preferably, a placement hole is provided at the center of the substrate, and sliding grooves are provided at both ends of the substrate. Symmetrically distributed guide posts are fixed inside the sliding grooves. A telescopic spring is sleeved on the outside of the guide posts. An extension plate is also provided inside the sliding groove. The guide posts are inserted into the extension plate and slidably connected to the extension plate. Symmetrically distributed positioning posts are provided on the lower outer side of the extension plate. The positioning posts are fixedly connected to the extension plate.

[0010] Preferably, the stepper motor is located above the mounting plate and is fixed to the mounting plate by bolts. One side of the spur gear is provided with an external gear ring that meshes with it. The inside of the external gear ring is provided with a winding wheel that is fixedly connected. The inside of the winding wheel is provided with a hollow tube that is fixedly installed. The inside of the hollow tube is provided with a flow groove.

[0011] The hollow tube is rotatably connected to the mounting frame, and the sampling tube is wound around the outer side of the inner winding wheel of the mounting frame.

[0012] Preferably, one end of the sampling tube passes through the take-up reel and is inserted into the flow groove inside the hollow tube. The other end of the sampling tube is fixedly installed with a sampling head. The outer side of the sampling head has axially distributed openings. A rotary joint is installed on the top of the bracket by bolts. The rotatable end of the rotary joint is fixedly connected to the hollow tube by a flange.

[0013] Preferably, the other end of the rotary joint is provided with a fixedly connected flexible and rigid tube, and a peristaltic pump is installed on one side of the mounting bracket two by bolts. One end of the flexible tube inside the peristaltic pump is fixedly connected to the flexible and rigid tube and is internally connected. The other end of the flexible tube inside the peristaltic pump is fixedly connected to the faucet and is internally connected.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention involves placing the device above the ethanol storage tank to be sampled, then pulling out the extension plates at both ends of the base plate, and then locking the positioning post on the outside of the storage tank to complete the limiting installation of the device. This makes the device more stable during sampling and prevents leakage. After the base plate is installed, the stepper motor is started to drive the sampling tube to perform the tube placement operation, so that the sampling head slides down from the placement hole into the ethanol liquid. The sampling depth of the sampling head can be controlled by controlling the number of rotations of the stepper motor. After reaching the desired sampling depth, the peristaltic pump is started to complete the ethanol sampling. Attached Figure Description

When it is necessary to install this device on an ethanol storage tank, first pull out the extension plate 21 from the inside of both ends of the substrate 1, and then lock the positioning post 22 on the outside of the storage tank to complete the limiting installation of this device.

[0026] The mounting frame 11 is equipped with a sampling control mechanism 3, which includes a stepper motor 31. The stepper motor 31 is located above the mounting plate 12 and is fixed to the mounting plate 12 by bolts. The drive shaft of the stepper motor 31 passes through the mounting frame 11 and is fixedly equipped with a spur gear 32. One side of the spur gear 32 is equipped with a meshing external gear ring 33. The external gear ring 33 is equipped with a fixedly connected winding wheel 35. The winding wheel 35 is equipped with a fixedly installed hollow tube 34. The hollow tube 34 has a flow groove inside. The hollow tube 34 is rotatably connected to the mounting frame 11. The sampling tube 36 is wound around the outside of the winding wheel 35 inside the mounting frame 11.

[0027] One end of the sampling tube 36 passes through the take-up reel 35 and is inserted into the flow groove inside the hollow tube 34.
