[0041] Working principle: The treated waste liquid of the carbide slag filter pressing dewatering device body 1 flows into the box 202 of the impurity interception assembly 2 through the communication pipe 201, and the communication pipe 201 ensures that the waste liquid can be smoothly transmitted from the filter pressing dewatering device to the box 202. After the waste liquid enters the box 202, it first contacts the first filter screen 209 in the frame 208. After a period of filtration, a certain amount of impurities will accumulate on the first filter screen 209, affecting the filtration effect. At this time, the motor body 211 in the frame 208 is started, and the left threaded rod 212 is rotated under the drive of the motor. Since the adjusting block 213 is threadedly connected with the threaded rod 212, under the rotation of the threaded rod 212, the adjusting block 213 moves in the adjusting groove 210 at the rear side of the frame 208. The scraper 214 fixedly connected to the front side of the adjusting block 213 moves horizontally with the movement of the adjusting block 213. The impurities scraped off by the scraper 214 slide down through the inclined groove 215 at the bottom of the frame 208 under the action of gravity, facilitating the smooth sliding of the impurities and preventing the impurities from accumulating in the groove. The second filter screen 216 fixedly connected inside the inclined groove 215 filters the sliding impurities again. The mesh of the second filter screen 216 is finer than that of the first filter screen 209, which can further intercept the fine particles remaining in the impurities and allow a small amount of liquid contained in the impurities to drip through the mesh back to the inner wall bottom of the box 202, achieving further separation of the liquid and the impurities, improving the dryness of the impurities, and facilitating subsequent processing. While the impurities are being cleaned or after the cleaning is completed, the user prepares to transfer the filtered liquid at the inner wall bottom of the box 202 to the secondary filtration mechanism 3. The water pump body 203 at the top of the box 202 is started, and the water pump extracts the filtered liquid from the inner wall bottom of the box 202 through the first connecting pipe 205 at the bottom. One end of the first connecting pipe 205 penetrates the partition plate 204 into the liquid area, ensuring that the extracted liquid is pure and free of impurities. Then the user adjusts the servo motor body 305 to adjust the stirring frame 306 to stir the liquid. During the stirring process, the liquid inside the storage barrel 301 is heated by the plurality of heating rods 307. Then the liquid is heated uniformly by stirring. After uniform heating, the liquid produces steam to decompose the impurities with the water source. Then, under appropriate decomposition conditions, the user adjusts the electronic valve body 3021 bolted inside the mounting hole 3028. Then the steam enters the inside of the gas outlet pipe 3022. Then the steam enters the inside of the L-shaped frame 3025. The air purification screen frame 3027 fixedly connected in the connecting frame 3026 adsorbs impurities from the steam. Then the gas contacts the inner wall of the box shell 3023. Then the steam is filtered again by the hollow purification screen frame. After the second filtration is completed, the gas is discharged through the exhaust pipe 3024, thereby achieving the effect of facilitating the filtration of the gas.

[0042] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
