[0031] See also Figure 1-4 As shown, this embodiment is a demisting structure of a graphite digestion instrument, comprising:

[0032] Graphite digestion apparatus 1;

[0033] The demisting assembly includes a demisting adsorption frame 21, a first guide pipe 22, a suction pump 23, a second guide pipe 24, and a neutralization box 25;

[0034] The mist exhaust adsorption rack 21 is arranged directly above the graphite digestion instrument 1, and one end of the first guide pipe 22 is connected to the middle of the upper end of the mist exhaust adsorption rack 21, the other end of the first guide pipe 22 is sleeved and connected to the input end of the suction pump 23, and the output end of the suction pump 23 is sleeved to one end of the second guide pipe 24, the other end of the second guide pipe 24 is connected to the middle of the upper end of the neutralization box 25, and the neutralization box 25 has a built-in sodium hydroxide solution;

[0035] The mist exhaust adsorption rack 21 cooperates with the suction pump 23 to extract and adsorb the acid mist generated by the graphite digestion instrument, the first guide pipe 22 and the second guide pipe 24 are used to guide the adsorbed acid mist, and the neutralization box 25 collects the guided input acid mist and neutralizes it through a neutralization reaction with sodium hydroxide;

[0036] It also includes a lifting assembly, which includes a bracket 41, a mounting block 42, and an electric push rod 43;

[0037] The bracket 41 is arranged at the ends of both sides of the graphite digestion instrument 1, and the mounting block 42 is fixedly connected to the lower end of the outer side of the bracket 41, and the electric push rod 43 passes through the middle of the inner end of the mounting block 42;

[0038] The bracket 41 performs structural installation on the mounting block 42, and the mounting block 42 satisfies the installation of the electric push rod 43 structure, and the electric push rod 43 provides the force required for the demisting adsorption frame 21 to rise and fall;

[0039] The ends of both sides of the mist exhaust adsorption frame 21 are provided with rectangular protrusions, and the rectangular protrusions extend out of the guide grooves opened in the middle of the bracket 41, and the output end of the electric push rod 43 is fixed to the lower end of the rectangular protrusion;

[0040] The rectangular protrusions mount the demisting adsorption frame 21 and the electric push rod 43. The sliding of the rectangular protrusions in the guide grooves satisfies the up and down movement of the demisting adsorption frame 21 and reduces the friction generated by the movement.

[0041] A universal wheel 44 is rotatably connected in the middle of the lower end of the bracket 41;

[0042] The universal wheel 44 satisfies the position movement of the lifting assembly;

[0043] A support 45 is connected to the lower end of the bracket 41 above the universal wheel 44, and one end of the support 45 extends out of the bracket 41 and is fixedly connected to a handrail 46.

[0044] The support column 45 is used to fix the structure of the handrail frame 46, and the handrail frame 46 can facilitate structural support and control;

[0045] Working principle: The armrest 46 applies a pushing force to the bracket 41, and the bracket 41 is moved by rolling between the universal wheel 44 and the ground. When the bracket 41 moves to the ends of both sides of the graphite digestion instrument 1, the demisting adsorption frame 21 is located directly above the graphite digestion instrument 1;

[0046] At this time, the end of the first guide pipe 22 is fixed to the input end of the suction pump 23 and the middle of the upper end of the mist exhaust adsorption frame 21, and the end of the second guide pipe 24 is fixed to the output end of the suction pump 23 and the middle of the sealing cover 31;

[0047] Next, the controlled suction pump 23 cooperates with the first guide pipe 22 to extract the generated acid mist through the mist exhaust adsorption frame 21, and inputs it into the neutralization box 25 through the second guide pipe 24, and then it is discharged after neutralization treatment through the reaction with sodium hydroxide;

[0048] This solution can prevent acid mist from being discharged into the environment and causing environmental pollution.

[0049] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1 and further includes a sealing assembly, which includes a sealing cover 31, a sealing gasket 32, and a pressure sensor 33;

[0050] The sealing cover 31 is buckled in the middle of the upper end of the neutralization box 25, and the sealing gasket 32 ​​is filled in the connection gap between the sealing cover 31 and the neutralization box 25. The pressure sensor 33 is connected through the upper middle part of one side of the neutralization box 25.

[0051] The sealing cover 31 cooperates with the sealing gasket 32 ​​to seal the upper part of the neutralization box 25, and the pressure sensor 33 performs sealing detection on the inside of the neutralization box 25 to avoid leakage of acid mist;

[0052] Working principle: Before the acid mist is put into the neutralization box 25, the middle part of the upper end of the neutralization box 25 is sealed in advance using a sealing cover 31 and a sealing gasket 32, and a pressure sensor 33 is used to perform a sealing test;

[0053] This solution can ensure the internal sealing of the neutralization box 25, and prevent the acid mist from leaking during the neutralization process and being discharged into the environment to pollute the environment.
