[0002] With the continuous progress of society and the continuous development of industrial technology, the amount of industrial gas emissions is also increasing. If it is not treated first and is directly discharged into the atmosphere, it will cause air pollution at the very least, and harm the ecological environment and even endanger life safety at the worst.

[0003] The exhaust gas recovery and purification treatment device is a circulating pipeline passage. Since epoxysilane synthetic exhaust gas is continuously injected at one end, it enters the purification system through the pipeline and is then discharged. During this period, exhaust gas continues to enter and exit. When it passes through the purification device, it needs to be filled with the required reagents, and it can be discharged after it reacts and is purified. However, the existing exhaust gas collection and purification device lacks a good reagent filling structure, resulting in the added reagents being able to mix and react with the exhaust gas only near the filling port, greatly limiting the purification rate. Moreover, the precipitation of dust particles in the exhaust gas may also cause blockage of the filling port. Therefore, it is necessary to develop a new exhaust gas purification treatment device that accelerates the diffusion of reagents and can avoid blockage of the air inlet. Utility Model Content

DETAILED DESCRIPTION

[0024] The feeding assembly 2 includes a linkage assembly 21 movably mounted on the bottom of the purification box 1, the side of the linkage assembly 21 is connected to the driving motor, the bottom of the linkage assembly 21 is connected to the feeding assembly 22, the upper end of the linkage assembly 21 extends to the interior of the purification box 1 and is fixedly connected to a dispersion cover 26, and the outer surface of the dispersion cover 26 is fixedly connected to a plurality of evenly distributed stirring plates 27; due to the setting of the dispersion cover 26, the utility model can make the incoming purification reagent quickly diffuse into the interior of the purification box 1 with the cooperation of the stirring plate 27, and due to the stirring effect of the stirring plate 27 on the exhaust gas, it can further promote the full mixing of the exhaust gas and the purification reagent, thereby improving the purification rate.

[0025] like Figure 3As shown, the linkage assembly 21 includes a linkage ring 211 movably sleeved inside the purification box 1, and the outer surface of the linkage ring 211 is sealingly sleeved with the purification box 1; the outer surface of the linkage ring 211 is also fixedly sleeved with a positioning bearing 25, and the outer side of the positioning bearing 25 is fixedly sleeved inside the purification box 1.

[0026] like Figure 3 As shown, a reinforced connecting shaft 212 is passed through the middle of the linkage ring 211, the inner diameter of the linkage ring 211 is larger than the outer diameter of the reinforced connecting shaft 212, and a feeding spiral blade 213 is provided between the linkage ring 211 and the reinforced connecting shaft 212, and the two sides of the feeding spiral blade 213 are respectively fixedly connected to the inner wall of the linkage ring 211 and the outer surface of the reinforced connecting shaft 212; due to the setting of the feeding spiral blade 213, the purpose of actively filling the purification reagent can be achieved with the cooperation of the driving motor and the driving gear 3, and then the rotation efficiency of the transmission gear 214 can be adjusted by the driving motor, thereby adjusting the filling rate of the purification reagent.

[0027] like Figure 3 and Figure 4 As shown, the outer surface of the linkage ring 211 is fixedly sleeved with a transmission gear 214 located below the purification box 1, and the side of the transmission gear 214 is meshedly connected with a driving gear 3, and the driving gear 3 is fixedly sleeved on the outer end of the output shaft of the driving motor;

[0028] The outer surface of the driving gear 3 includes a toothed arc surface and a smooth arc surface. The toothed arc surface is meshed with the outer surface of the transmission gear 214 , and the smooth arc surface does not contact the outer surface of the transmission gear 214 .

[0029] As shown in the figure and Figure 3 As shown, the feed assembly 22 includes a limit clamp ring 221 fixedly connected to the bottom of the linkage ring 211, and a feed pipe 222 is movably sleeved inside the limit clamp ring 221. The upper end of the feed pipe 222 is connected to the inside of the linkage ring 211, and an intake check valve is arranged at the lower end of the feed pipe 222;

[0030] The lower end of the limiting clamp ring 221 is sealingly sleeved on the outer surface of the feed pipe 222 , and a limiting ring 223 is sleeved between the upper end of the limiting clamp ring 221 and the feed pipe 222 . The limiting ring 223 is fixedly sleeved on the outer surface of the feed pipe 222 .

[0031] like Figure 3As shown, the outer surface of the linkage ring 211 is movably sleeved with a positioning ring 23, and the positioning ring 23 is fixedly connected to the purification box 1. The cross-section of the positioning ring 23 is a horizontal "L" shape. A clockwork spring 24 is arranged inside the positioning ring 23, and one end of the clockwork spring 24 is fixedly connected to the inner wall of the positioning ring 23, and the other end of the clockwork spring 24 is fixedly connected to the outer surface of the linkage ring 211; due to the arrangement of the clockwork spring 24, with the cooperation of the active gear 3, the driving motor can continuously and intermittently drive the linkage ring 211 to rotate, and then with the cooperation of the air intake check valve, the linkage component 21 gold hook can complete the function of automatic feeding, and at the same time can achieve the function of shaking off the precipitated particles on the surface of the dispersion cover 26, thereby achieving the effect of preventing the exhaust dust particles from clogging the dispersion cover 26.

[0032] The working principle and use process of this utility model:

[0033] The collected tail gas to be purified is injected into the purification box 1, and the device is turned on to run the driving motor at the bottom, so that the driving gear 214 can be driven to rotate continuously and intermittently through the driving gear 3. When the driving gear 214 rotates, the linkage ring 211, the reinforcing connecting shaft 212 and the feeding spiral blade 213 can be driven to rotate as a whole. Due to the rotation of the feeding spiral blade 213, the purification reagent can be drawn in with the cooperation of the feeding component 22, and enter the interior of the purification box 1 through the through hole on the surface of the dispersion cover 26, and react with the gas to be purified;

[0034] The rotation of the linkage ring 211 can drive the stirring plate 27 and the spring spring 24 to move at the same time. The rotation of the stirring plate 27 can fully stir the surrounding gas to avoid the precipitation of the exhaust gas inside the purification box 1, and can promote the purification reagent newly injected into the dispersion cover 26 to spread quickly, so that it can be quickly and fully mixed with the exhaust gas.

[0035] The movement of the spring 24 can twist the spring 24 when the linkage ring 211 rotates under the restriction of the positioning ring 23, thereby increasing its elastic restoring force. When the notch on the surface of the driving gear 3 rotates to the transmission gear 214, the feeding assembly 2 can be quickly reversed as a whole under the elastic restoring action of the spring 24, so that it vibrates to prevent dust and other particles in the exhaust gas from falling onto the surface of the dispersion cover 26 and causing the through hole to be blocked.

[0036] Since an air intake check valve is provided inside the lower end of the feed pipe 222, the reverse rotation of the feeding spiral blade 213 to discharge gas can be avoided.
