[0002] Arsine is a toxic gas, usually mixed in industrial waste gas. It needs to be treated by adsorbing the arsenic in the waste gas through an adsorbent. There are many types of chemical agents in the catalyst, and the chemical agents need to react and adsorb the arsenic gas together. After the gas reacts with a chemical agent, a new compound will be formed. The compound needs to contact and react with another chemical agent to form another new non-toxic compound. When the two chemicals are far apart, the efficiency of the reaction will be low, affecting the adsorption efficiency of arsenic.

[0003] Therefore, when adsorbing hydrogen arsenide, different chemicals need to be mixed to speed up the adsorption effect of hydrogen arsenide. Usually, different chemicals are placed in a tank and stirred by a stirring mechanism. However, the stirring mechanism cannot fit the edge of the inner wall of the tank. There will be a space between the stirring mechanism and the tank, resulting in some chemicals being in the space and unable to be completely mixed and used, which affects the full utilization of the chemicals.

[0018] Example

[0019] Please refer to Figure 1-Figure 3 The present invention proposes an arsenic hydrogen adsorbent mixing device, comprising a cylinder 1, a stirring device 2 coaxial with the cylinder 1 is arranged at the center of the cylinder 1, a sub-stirring mechanism 3 is arranged in the interval between the stirring device 2 and the inner wall of the cylinder 1, the sub-stirring mechanism 3 and the stirring device 2 are connected by a connecting rod 4, and the stirring device 2 can drive the sub-stirring mechanism 3 to rotate when the stirring device 2 rotates in the cylinder 1; in this scheme, when the stirring device 2 is running, the space range of 85% of the radius of the central area of ​​the cylinder 1 can be stirred, because the chemical agent is in the form of solid powder, the powder may be in the interval between the stirring device 2 and the inner wall of the cylinder 1, the sub-stirring mechanism 3 can be located in the interval to fully stir the powder, and can prevent the powder from being located between the stirring device 2 and the inner wall of the cylinder 1.

[0020] In a specific embodiment, refer to Figure 2 , the auxiliary stirring mechanism 3 is rotatably connected to the connecting rod 4; in this scheme, when the stirring device 2 is running, it will rotate with the axis of the cylinder 1, and the auxiliary stirring mechanism 3 can rotate around the axis of the cylinder 1 under the action of the connecting rod 4. At the same time, the auxiliary stirring mechanism 3 itself can also rotate relative to the connecting rod 4 to stir the chemical powder on the inner edge of the cylinder 1.

[0021] In a specific embodiment, refer to Figure 2 , Figure 3The auxiliary stirring mechanism 3 includes a auxiliary shaft body 31 and a rod-shaped stirring column 32. One end of the auxiliary shaft body 31 is rotatably connected to the end of the connecting rod 4 away from the axis of the cylinder 1. The auxiliary shaft body 31 is spirally opened with a plurality of penetrating holes 311, and the stirring column 32 is inserted into the hole 311; in this scheme, when the auxiliary stirring mechanism 3 rotates and rotates on the axis of the cylinder 1 in the cylinder 1, when the auxiliary shaft body 31 rotates, the gap between one end of the hole 311 and the inner wall of the cylinder 1 will continue to decrease, thereby squeezing the stirring column 32 in the hole 311 to slide, and causing the stirring column 32 to slide out from the other end of the hole 311. The stirring column 32 can increase the stirring radius of the auxiliary shaft body 31, and can facilitate the stirring column 32 to stir the chemical powder on the edge of the cylinder 1. At the same time, the sliding of the stirring column 32 can reduce the wear on the inner wall of the cylinder 1 and improve the service life.

[0022] In a specific embodiment, refer to Figure 2 , Figure 3 , the length of the stirring column 32 is greater than the diameter of the circular cross-section of the secondary shaft body 31; in this solution, the stirring column 32 needs to always leak out of the hole 311 to have a stirring effect. Therefore, the length of the stirring column 32 needs to be ensured to be greater than the length of the hole 311. The maximum length of the hole 311 is the diameter length of the cross-section of the secondary shaft body 31. Therefore, when one end of the stirring column 32 is squeezed in the hole 311, the stirring column 32 can leak out from the other end of the hole 311. The stirring column 32 in this solution is installed horizontally.

[0023] In a specific embodiment, refer to Figure 2 , Figure 3 , an annular tooth key 11 is provided at the upper edge of the cylinder 1, and the upper end of the auxiliary shaft body 31 is connected to a gear 33 meshing with the annular tooth key 11; in the present application, the rotation of the stirring column 32 relative to the connecting rod 4 can be driven independently by the driving mechanism 23, or it can be driven passively. The passive driving method is adopted in this scheme. When the entire auxiliary stirring mechanism 3 rotates relative to the axis of the cylinder 1 under the action of the connecting rod 4, the auxiliary shaft body 31 will rotate along the inner wall of the cylinder 1, and the gear 33 can mesh with the annular tooth key 11, so that the auxiliary shaft body 31 rotates relative to the connecting rod 4.

[0024] In a specific embodiment, refer to Figure 3 The secondary shaft 31 rotates to force the stirring column 32 to slide in the hole 311 .

[0025] In a specific embodiment, refer to Figure 1 The cylinder 1 is respectively provided with a feed port and a discharge port; the feed port and the discharge port correspond to the feed function and the discharge function respectively.

[0026] In a specific embodiment, refer to Figure 2The stirring device 2 includes a main shaft body 21 and stirring blades 22. The main shaft body 21 is rotatably installed at the axis of the cylinder body 1. The stirring blades 22 are arranged along the radial direction of the cylinder body 1 and connected to the main shaft body 21. A driving mechanism 23 connected to the main shaft body 21 is arranged above the cylinder body 1; in this scheme, the driving mechanism 23 is a motor with controllable speed, which drives the stirring device 2 to operate through the main shaft body 21, and then drives the auxiliary stirring mechanism 3 to operate, so as to stir the chemical powder in the cylinder body 1 and fully mix and stir the powder.
