Description

Technical Field

[0001] This application relates to the field of methanesulfonic acid production technology, specifically to a sampling device for methanesulfonic acid production. Background Technology

[0002] Methanesulfonic acid is a colorless or slightly brown oily liquid, solid at low temperatures. It is soluble in water, alcohols, and ethers, but insoluble in alkanes, benzene, toluene, etc. It does not decompose in boiling water or hot alkaline solutions, but it has a strong corrosive effect on metals such as iron, copper, and lead. This product has a strong irritant effect on skin and mucous membranes, but its toxicity is less than that of methylsulfonic acid. It is generally used as a raw material in pharmaceuticals and pesticides, and can also be used as a dehydrating agent and a coating curing accelerator. It is one of the important chemical raw materials.

[0003] During the production of methanesulfonic acid, it is necessary to periodically test the produced methanesulfonic acid to determine its concentration and the content of other substances. This requires the use of a sampling device for sampling. In the existing technology, the worker holds the sampling device with one hand to directly draw the methanesulfonic acid and then injects it into the sampling bottle held by the other hand. If the worker is not careful during the injection process, he may come into contact with the methanesulfonic acid, which poses a safety risk. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical deficiencies and provide a sampling device for the production of methanesulfonic acid, which solves the problem of safety risks during sampling and injection in existing methanesulfonic acid sampling devices.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this application is as follows: A sampling device for the production of methanesulfonic acid includes an extraction box, an extraction pipe, sliding blocks, a drive rod, and a magnetic unit, wherein: the inlet of the extraction pipe is connected to the extraction box; a sliding cavity is formed on the lower side of the extraction box; two sliding blocks are disposed in the sliding cavity and slidably connected to the sliding cavity, the two sliding blocks together forming a clamping opening for clamping a sampling bottle, and the outlet of the extraction pipe is disposed above the clamping opening; the drive rod is movably disposed at least partially in the sliding cavity; the magnetic unit is disposed between the drive rod and at least one of the sliding blocks; the drive rod can movably switch to allow different magnetic units to cooperate, thereby generating attraction or repulsion between the drive rod and the sliding blocks, so as to drive the sliding blocks to slide in two opposite directions, thereby changing the size of the clamping opening.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Please see Figure 1 and Figure 2 This embodiment provides a sampling device for the production of methanesulfonic acid, including an extraction box 1, an extraction pipe 2, a sliding block 3, a drive rod 4, and a magnetic unit 5.

[0021] The inlet of extraction pipe 2 is connected to extraction box 1 and is used to extend into methanesulfonic acid. A liquid pump can be installed in extraction box 1 and connected to extraction pipe 2. A sliding cavity 1a is opened on the lower side of extraction box 1 for installing other components.

[0022] Two sliding blocks 3 are set in the sliding cavity 1a and are slidably connected to the sliding cavity 1a. The sliding direction is roughly horizontal. The two sliding blocks 3 together form a clamping opening 3a for clamping the sampling bottle 7. Therefore, the sampling bottle 7 is usually designed with a bayonet, with a recessed part that fits into the clamping opening 3a to ensure that the clamping opening 3a is stable enough when clamping the sampling bottle 7. The outlet of the extraction pipe 2 is set above the clamping opening 3a, and the methanesulfonic acid pumped by the liquid pump is sent into the sampling bottle 7 at the clamping opening 3a.

[0023] Preferably, the two sliding blocks 3 extend upward / downward from the side away from each other to form an abutment portion 3b. The upper / lower side of the abutment portion 3b abuts against the top / bottom of the sliding cavity 1a. In this embodiment, the two sliding blocks 3 extend upward from the side away from each other to form an abutment portion 3b. The upper side of the abutment portion 3b abuts against the top of the sliding cavity 1a, and the lower side of the sliding block 3 abuts against the bottom of the sliding cavity 1a.

[0024] The drive rod 4 is movably disposed at least partially within the sliding cavity 1a. Specifically, the two ends of the drive rod 4 extend to form two drive portions 4a, each corresponding to one of the two abutment portions 3b. A magnetic unit 5 is disposed between the drive portions 4a and the abutment portions 3b. Preferably, the drive portions 4a and the abutment portions 3b are slidably connected, so the direction of movement of the drive portions 4a is the same as the direction in which the abutment portions 3b are formed. Preferably, the abutment portions 3b are positioned close to their respective drive portions 4a, i.e., the two drive portions 4a are disposed inside the abutment portions 3b.

[0025] A magnetic unit 5 is disposed between the drive rod 4 and at least one sliding block 3. Specifically, the magnetic unit 5 includes a first magnet 5a, a second magnet 5b, and a third magnet 5c. The first magnet 5a is fixed to the side of the drive part 4a near the abutment part 3b, and the second magnet 5b and the third magnet 5c are fixed to the side of the abutment part 3b near the drive part 4a. The line connecting the second magnet 5b and the third magnet 5c is in the same direction as the movement direction of the drive rod 4. The first magnet 5a, the second magnet 5b, and the third magnet 5c can be made of a strong magnetic material, such as neodymium iron boron magnets.

[0026] The drive rod 4 can be movably switched to engage different magnetic units 5, generating attraction or repulsion between the drive rod 4 and the sliding block 3 respectively, thereby driving the sliding block 3 to slide in two opposite directions and changing the size of the clamping opening 3a. Specifically, when the drive rod 4 moves to align the first magnet 5a with the second magnet 5b, the clamping opening 3a shrinks; when the drive rod 4 moves to align the first magnet 5a with the third magnet 5c, the clamping opening 3a expands.

[0027] Preferably, the sampling device for methanesulfonic acid production further includes an elastic unit 6, one end of which abuts against the drive rod 4, and the other end of which abuts against the sliding cavity 1a. More preferably, the elastic unit 6 is a spring. In this embodiment, the elastic unit 6 causes the drive part 4a to move outward, simultaneously aligning the first magnet 5a with the second magnet 5b. That is, initially, the clamping opening 3a is narrowed. When the drive rod 4 is pressed or pushed inward, the first magnet 5a switches to engage with the third magnet 5c. At this time, the repulsive force between the first magnet 5a and the third magnet 5c causes the sliding block 3 to move away from each other, expanding the clamping opening 3a beyond the mouth of the sampling bottle 7, allowing the sampling bottle 7 to be easily removed. In this embodiment, the clamping opening 3a is circular to accommodate the circular opening of the sampling bottle 7.

[0028] Preferably, a funnel-shaped sliding opening 3c is formed on the lower side of the sliding block 3. Generally, the lower diameter of the sliding opening 3c is larger than the diameter of the mouth of the sampling bottle 7. When the sampling bottle 7 is pushed upward to abut against the sliding opening 3c, and continues to be pushed, the two sliding blocks 3 will move in a direction away from each other, and the clamping opening 3a will expand until the recess of the sampling bottle 7 is inserted into the clamping opening 3a.

[0029] In summary, the sampling device for methanesulfonic acid production provided in this application allows for the movement of the drive rod 4, which can switch between different magnetic units 5 to generate attraction or repulsion between the drive rod 4 and the sliding block 3, thereby driving the sliding block 3 to slide in two opposite directions and changing the size of the clamping opening 3a. After the clamping opening 3a is enlarged, the sampling bottle 7 can be inserted. Due to the magnetic force between the sliding block 3 and the drive rod 4, the sampling bottle 7 can be stably clamped. After the clamping opening 3a is enlarged, the sampling bottle 7 can be removed. The installation and removal are quick and easy. Methanesulfonic acid is drawn into the sampling bottle 7 from the extraction box 1 through the extraction pipe 2. During the sampling and injection process, workers will not be at risk of contact with methanesulfonic acid.

[0030] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
