[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: First, through the periodic lifting movement of the inwardly convex lifting box and the bubble ejection of the corrugated telescopic tube, the rapid separation and collection of oil and dirt is achieved.

[0015] Third, the sewage enters the conical pipe and forms a hydraulic cyclone with the spiral tooth structure. The pressure of the sediment in the sewage drives the formation of a centrifugal field, which enables accurate classification of light and heavy sediments. The heavy sediment settles and is discharged along the cone wall, and the light sediment is separated through the overflow pipe. This classification mechanism provides data support for subsequent differentiated treatments such as optimization of chemical ratios, significantly reducing the amount of chemical agents used and the cost of sludge treatment.

[0023] Reference Figure 8, and also includes a sediment separation component 4, which includes a water accumulation tray 401 fixedly installed on the lower end surface of the filter tank 201, a liquid level sensor fixedly installed on the inner wall of the water accumulation tray 401, and the liquid level sensor is electrically connected to the controller. The liquid level sensor is an existing device, which is used to detect the liquid level height of a liquid (such as water, oil, chemical liquid, etc.) in a container, a pipeline or a storage tank, and can convert the liquid level change into an electrical signal output. The water accumulation tray 401 is embedded with an overflow pipe 402, and the upper end of the overflow pipe 402 is fixedly connected to the filter tank 201. A conical pipe 403 is fixedly installed on the lower end surface of the water accumulation tray 401 and on the outer side of the overflow pipe 402.

The water pump 405 is electrically connected to the controller. Through the setting of the sediment separation component 4, in the process of sewage entering the conical tube 403, the threaded teeth allow the water flow to form a high-speed rotating spiral flow, and the heavier sediment and the lighter sediment in the sewage will be separated by the high-speed rotating spiral flow along with the flow of sewage.

[0024] The working principle of the present invention is as follows: 1. Filter impurities: Intermittently discharge sewage within a quantitative range into the filter tank 201 through the water inlet 202, and the impurities in the sewage will be filtered through the filter holes opened in the discharge cone plate 203, and the impurities will remain on the upper end surface of the discharge cone plate 203, and the upper end surface of the discharge cone plate 203 is set with an inclined surface. The impurities will slide on the upper end of the discharge cone plate 203 and slide toward the inner wall of the filter tank 201. In the process of entering the filter tank 201, the sewage will impact the rotating disk 207 and drive the rotating disk 207 to rotate (the upper end surface of the rotating disk 207 is provided with an oblique tooth groove, and the direction of the rotation connection between the rotating disk 205 and the support 204 is fixed, refer to Figure 3 The rotating disk 207 will drive the short shaft 206, the rotating disk 205 and the scraper 208 to rotate during the rotation process. The rotating scraper 208 will push the impurities to move on the upper end surface of the discharge cone plate 203. When the impurities are pushed to the discharge port 213, the impurities will enter the discharge port 213, and the first spring 210 will push the connecting rod 211 and the push plate 212 in the slide groove 209 to slide in the discharge port 213, and push the impurities to the upper end surface of the discharge cone plate 203. The impurities will slide from the discharge chute 101, and the push plate 212 will drive the connecting rod 211 to compress the first spring 210 and slide with the inner wall of the slide groove 209 as the discharge cone plate 203 rotates and contacts and squeezes the discharge inclined surface, and the impurities sliding from the discharge chute 101 are collected uniformly; 2. Filtering oil pollution: After filtering impurities, the sewage falls from the filter holes to the top of the inner convex lifting box 305 for accumulation. After accumulating to a preset height, it will enter the oil filter space through the water outlet 306 and drip into the water accumulation tray 401 through the drip valve 322. The inner diameter of the filter hole is larger than the inner diameter of the water outlet end of the drip valve 322. Therefore, the sewage entering the top of the inner convex lifting box 305 and the oil filter space will accumulate, and the density of oil pollution in the sewage is smaller than the density of water. In the process of the accumulated sewage slowly being discharged through the drip valve 322 in the oil filter space, the flow speed will be relatively slow, and the oil pollution will float in the sewage and float to the inner convex lifting box 305 through the water outlet 306. In the process of the rotating column 301 being driven to rotate and driving the lifting sleeve 302 to rise and fall, the lifting sleeve 302 will The inner convex lifting box 305 is driven to rise together. During the rising process of the inner convex lifting box 305, the floating oil dirt is also driven to rise together. The water outlet 306 is slidably connected with the clamping column 308 to prevent the oil dirt from flowing back into the oil filter space from the water outlet 306. During the rising process of the inner convex lifting box 305, the cross bar 309 is driven to rise and squeeze and contact with the clamping block 312. The clamping block 312 compresses the second spring 311 and slides in the groove 310 to connect the arc-shaped collecting box 313 with the filter tank 201. Since the inner bottom end of the inner convex lifting box 305 is set as a convex surface, during the rising process of the inner convex lifting box 305, the oil dirt floating in the inner convex lifting box 305 will flow toward the inner wall of the filter tank 201, and finally flow into the arc-shaped collecting box 313 and be discharged and collected outside through the discharge pipe 314. During the process of the inner convex lifting box 305 descending, the water outlet 306 and the clamping column 308 slide and misalign to generate a gap, so that the falling sewage can flow back into the oil filter space from the water outlet 306; When the lifting sleeve 302 is driven to lift, the fixed bracket 315 is also lifted and lowered. When the fixed bracket 315 descends, the bellows expansion tube 318 is compressed, so that the air in the bellows expansion tube 318 is sprayed into the annular jet pipe 324 through the second one-way valve 321 and the air inlet pipe 320. During the circulation, the air is sprayed out from the first air outlet provided in the air inlet pipe 320 and the second jet hole provided in the annular jet pipe 324. The air will enter the oil filter space and form bubbles from the inner bottom end of the oil filter space to float upward. During the process of floating bubbles, oil will adhere to the surface of the bubbles and float together with the bubbles, thereby accelerating the floating of oil in the sewage. During the process of driving the lifting sleeve 302 to rise, the outside air will enter the bellows expansion tube 318 through the first one-way valve 319. It should be noted that when the air is sprayed out from the second jet hole provided in the annular jet pipe 324, the bubbles will impact the angle between the inner convex lifting box 305 and the lifting sleeve 302, so as to prevent the oil from accumulating at the angle and being unable to flow. 3. Sludge weight classification: The sewage entering the water pan 401 through the drip valve 322 can detect the water level through the liquid level sensor. When the preset water level is reached, the liquid level sensor will generate an electrical signal corresponding to the water level. The controller controls the voltage input to the water pump 405 through the electrical signal to turn on the water pump 405. By turning on the water pump 405, the sewage in the water pan 401 is pumped out, and the sewage enters the conical tube 403 through the connecting pipe 404. Because the sewage transported by the water pump 405 has liquid pressure, and through the set spiral teeth, the sewage will form a high-speed rotating spiral in the process of entering the conical tube 403. The swirl flow (similar to a vortex) is a vortex flow in which the sewage forms a centrifugal force through rotation, forcing the heavier sediment to move to the bottom of the inner wall of the conical tube 403 and be discharged, while the lighter sediment will flow upward on the inner wall of the conical tube 403 through the centrifugal force, flow to the overflow pipe 402 and be discharged from the conical tube 403, thereby effectively separating the heavier sediment from the lighter sediment in the sewage. In this way, in the subsequent treatment of different sewage, the proportion of sewage treatment chemicals can be adjusted according to the different sediment weights contained in the sludge (such as the sewage flocculation stage), thereby reducing the demand for subsequent chemicals and reducing the cost of using chemicals; It should be noted that the sewage entering the conical tube 403 can drive the fan blades 304 to rotate through the spiral flow of the sewage, so that the fan blades 304 drive the transmission rod 303 and the rotating column 301 to rotate.
