[0001] The utility model relates to the technical field of catalyst feeding, and specifically relates to a catalyst feeding control mechanism for a catalytic oxidation device. Background Technique

[0002] The catalytic oxidation device is a new type of environmental protection technical equipment, mainly applied to the fields of industrial waste gas and wastewater treatment. Its working principle is to promote the oxidation and decomposition of pollutants through a catalyst to achieve the purpose of purification. The catalytic oxidation device mainly uses the catalyst to reduce the activation energy of the pollutant oxidation reaction, so that it reacts with oxygen at a lower temperature to generate harmless substances such as water and carbon dioxide.

[0003] During the process of adding the catalyst using the catalyst feeding mechanism, since the amount of catalyst added by different catalytic oxidation devices each time is different, if the amount of catalyst is too much or too little, it will affect the reaction rate. Therefore, a catalyst feeding control mechanism for a catalytic oxidation device is proposed to control the amount of catalyst flowing out. Content of the Utility Model

The warning device 307 is electrically connected to the trigger switch 306. An outlet cavity 4 is provided inside the storage tank 1. When the catalyst in the storage tank 1 gradually decreases, the floating block 304 will descend as the liquid level of the catalyst drops. The floating block 304 drives the slider 303 to slide on the slide rail 302. When the floating block 304 descends to a certain position, the trigger rod 305 fixed to its bottom will contact the trigger switch 306. After the trigger switch 306 is activated, it will send an electrical signal to the warning device 307.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in the initial state, the baffle plate 212 blocks the discharge hole of the discharge hopper 211, and the catalyst will not flow out. When it is necessary to add catalyst to the catalytic oxidation device, the servo motor 202 is started. The servo motor 202 drives the cam 204 to rotate through the connecting shaft 203. During the rotation of the cam 204, the internal chute 205 thereof will push the slide bar 206 to reciprocate horizontally. The slide bar 206 is connected to the fixed bar 208 through the connecting rod 207. Therefore, the fixed bar 208 will also move horizontally accordingly. The baffle plate 212 connected to the top of the fixed bar 208 will move along with the fixed bar 208. When the baffle plate 212 leaves the discharge hole of the discharge hopper 211, the catalyst can flow out from the storage tank 1 through the through groove 210 and the discharge hopper 211 to achieve feeding.

After the trigger switch 306 is activated, it will send an electrical signal to the alarm 307. After receiving the signal, the alarm 307 will give an audible and visual alarm to remind the operator that the catalyst in the storage tank 1 is about to be exhausted. At this time, the staff can supplement the catalyst through the feed pipe 7.
