[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the present invention is used, the driving motor is started to drive the rotating rod and a plurality of leveling claws to rotate, and the quartz sand filter medium inserted at multiple points is moved to make it evenly distributed inside the conical filter frame. At the same time, the push plate is rotated to level the quartz sand on the top to make it evenly distributed, thereby achieving the effect of uniform feeding and preventing the filter medium from being locally accumulated, which is beneficial to improving the filtering effect. After being cooled, the acrylic acid gas enters the scrubber through the air inlet pipe and flows upward. The high-pressure liquid pump is started in advance, and the washing absorption liquid is transported to the infusion pipe through the connecting pipe, and then enters the sprayer for atomization and spraying, forming a countercurrent contact with the acrylic acid gas rising from the bottom to form acrylic acid liquid. Then the acrylic acid liquid passes through the filter medium to separate the internal impurities.

[0021] 2. When the present invention is used, the vibrator is started to drive the vibration plate and the vibration rod to vibrate. Under the elastic support of the vibration spring, the feeding box is driven to vibrate up and down, and the top of the feeding box is protected by the elastic pad. At the same time, the feeding pipe is driven to vibrate inside the movable hole and the feeding port. The feeding pipe is protected by the elastic strip, so that the filter medium inside the feeding box enters the feeding port through the feeding pipe, then enters the scrubber, and finally falls into the conical filter frame, thereby achieving the effect of automatic feeding, without the need for manual filling bit by bit, reducing workload and time, and improving feeding efficiency. By equidistantly arranging multiple feeding ports and feeding boxes, the entry position of the quartz sand filter medium can be dispersed, which is conducive to the quartz sand being evenly scattered into the conical filter frame from different directions, thereby assisting in improving the feeding uniformity.

[0022] 3. When the present invention is used, the electric push rod is started to pull the inclined guide block to move downward, so that an inclined channel is formed between the discharge pipe and the inside of the discharge pipe. At this time, the filter medium enters the discharge pipe and slides along the inclined surface of the inclined guide block to the inside of the discharge pipe, thereby discharging the filter medium, thereby achieving the effect of automatic discharge. The driving motor is started again to make the rotating rod drive the discharge claw rake to rotate together, which is conducive to pushing the filter medium on the bottom surface of the inner bottom of the conical filter frame to the discharge pipe for discharge. The threaded cover is unscrewed, the fixed block and the electric push rod are pulled out of the discharge pipe, and the inclined guide block is further taken out of the discharge pipe, so as to facilitate the grinding of the inclined surface of the inclined guide block to make its inclined surface smoother, which is conducive to discharging the filter medium into the discharge pipe and preventing the inclined surface of the inclined guide block from being worn and affecting the smoothness.

[0023] 4. When the present invention is used, the hydraulic rod is started to push the moving block and the fixed rod downward, and the annular sealing plate is further pushed downward, so that the sealing ring moves downward along the inner wall of the scrubber. When the bottom of the annular sealing plate contacts the top of the conical filter frame, the sealing ring just seals the multiple feeding ports, thereby improving the sealing performance of the scrubber and preventing part of the acrylic acid gas from accidentally leaking out from the feeding port when the scrubbing assembly is working.

[0040] In this embodiment, when in use, five feeding ports 110, feeding pipes 206, feeding boxes 205 and feeding pipes 210 are provided, which are distributed along the circumference of the scrubber 101.

[0042] In this embodiment, when in use, after the quartz sand medium is evenly loaded through the loading and unloading assembly 2 and the uniform assembly 3, the hydraulic rod 405 is started to push the moving block 406 and the fixed rod 407 to move downward, and further push the annular sealing plate 403 to move downward along the inner wall of the scrubber 101, so that the sealing ring 404 moves downward along the inner wall of the scrubber 101. When the bottom of the annular sealing plate 403 contacts the top of the conical filter frame 301, the sealing ring 404 just seals the multiple feeding ports 110, thereby improving the sealing performance of the scrubber 101 and preventing part of the acrylic acid gas from accidentally leaking out from the feeding port 110 when the scrubbing assembly 1 is working.

[0043] The effect and working principle of the whole mechanism are as follows: the high-pressure liquid pump 104, the vibrator 204, the electric push rod 218, the drive motor 303, the hydraulic rod 405 and the PLC controller 5 are electrically connected, the vibrator 204 is started, the vibration plate 203 and the vibration rod 207 are driven to vibrate, and under the elastic support of the vibration spring 209, the five feeding boxes 205 are driven to vibrate up and down inside the vibration groove 220, and the top of the feeding box 205 is protected by the elastic pad 208, and at the same time, the five feeding pipes 210 are driven to vibrate inside the movable hole 212 and the feeding port 110, so that the quartz sand filter medium inside the feeding box 205 enters the feeding port 110 through the feeding pipe 210, and enters the scrubber along the inclined surface inside the feeding port 110 101, and finally falls into the conical filter frame 301, and the driving motor 303 is started to drive the rotating rod 305 and multiple leveling claws and rakes 307 to rotate. Through the rotation of multiple leveling claws and rakes 307, the quartz sand filter medium put into the conical filter frame 301 at multiple points is further moved to make it evenly distributed inside the conical filter frame 301. After the loading is completed, the quartz sand in the conical filter frame 301 is located at the bottom of the pushing plate 306. The quartz sand is evenly moved by multiple leveling claws and rakes 307, and the pushing plate 306 flattens the quartz sand on the top, so that the top quartz sand is evenly distributed, so as to achieve the effect of uniform loading, and the hydraulic rod 405 is started to push the moving block 406 and the fixed rod 407 to move downward, further pushing the annular The sealing plate 403 moves downward along the inner wall of the scrubber 101, so that the sealing ring 404 moves downward along the inner wall of the scrubber 101. When the bottom of the annular sealing plate 403 contacts the top of the conical filter frame 301, the sealing ring 404 just seals the multiple feeding ports 110.

The washing absorption liquid is sprayed downward in an atomized manner to form a gas with the acrylic acid gas rising from the bottom. Countercurrent contact, during this process, acrylic acid gas is absorbed by the absorbent to become acrylic acid liquid, and then the acrylic acid liquid is filtered through the quartz sand filter medium to separate the internal impurities. The filtered acrylic acid liquid falls on the bottom cover 106 and is discharged through the drain pipe 109. When the filter medium needs to be replaced, the electric push rod 218 is started to pull the inclined guide block 217 to move downward, so that an inclined channel is formed between the feed pipe 213 and the inside of the discharge pipe 214. At this time, the filter medium in the conical filter frame 301 enters the feed pipe 213 and slides along the inclined surface of the inclined guide block 217 to the inside of the discharge pipe 214, thereby discharging the filter medium, and starting the drive motor 303 again, so that the rotating rod 305 drives the feed claw rake 308 to rotate together,It is convenient to push the filter medium on the bottom surface of the conical filter frame 301 to the feed pipe 213 for feeding, rotate the threaded cover 216, unscrew it from the inside of the threaded hole 112 and the outer surface of the feed pipe 213, then pull out the fixing block 219 and the electric push rod 218 from the feed pipe 213, and further remove the inclined guide block 217 from the feed pipe 213, so as to facilitate grinding the inclined surface of the inclined guide block 217 to make its inclined surface smoother.
