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.

The inner diameter of the first air outlet hole is larger than the inner diameter of the second air outlet hole. A second one-way valve 321 is fixedly installed on the upper end of the air intake pipe 320. The air intake pipe 320 is arranged to inject air into the oil filter space during the compression and expansion of the bellows telescopic tube 318. The injected air will form bubbles in the sewage, allowing the oil to adhere and float to the water surface.

[0039] Reference Figure 8, also includes a sediment separation component 4, the sediment separation component 4 includes a water collection tray 401 fixedly installed on the lower end surface of the filter tank 201, a liquid level sensor is fixedly installed on the inner wall of the water collection tray 401, and the liquid level sensor is electrically connected to the controller.

Through the setting of the sediment separation component 4, in the process of sewage entering the tapered pipe 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.

[0040] The working principle of the present invention is as follows:

[0041] 1. Filter impurities: Intermittently discharge sewage within a quantitative range into the filter tank 201 through the water inlet 202. Impurities in the sewage will be filtered through the filter holes opened in the discharge cone plate 203. The impurities will remain on the upper end surface of the discharge cone plate 203. The upper end surface of the discharge cone plate 203 is inclined. The impurities will slide on the upper end of the discharge cone plate 203 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 chute 209 to slide in the discharge port 213, pushing the impurities out 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 contact and squeeze the discharge inclined surface as the discharge cone plate 203 rotates, and drive the connecting rod 211 to compress the first spring 210 and slide with the inner wall of the chute 209, and the impurities sliding from the discharge chute 101 will be collected uniformly.

[0042] 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 collection 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. The oil pollution will float in the sewage and float up 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 oil filter 301 of the embodiment of the present invention is the oil filter 302 of the embodiment of the present invention, and the oil filter 302 of the embodiment of the present invention is the oil filter 302 of the embodiment of the present invention.

[0043] During the descent of the inner convex lifting box 305, the water outlet 306 and the clamping column 308 slide and misalign to create a gap, which enables the falling sewage to flow back into the oil filter space from the water outlet 306.

[0044] When the lifting sleeve 302 is driven to rise and fall, the fixed support 315 is also lifted and lowered. When the fixed support 315 descends, the bellows 318 is compressed, so that the air in the bellows 318 is sprayed into the annular air injection pipe 324 through the second one-way valve 321 and the air inlet pipe 320. During the circulation, the air is ejected from the first air outlet provided in the air inlet pipe 320 and the second air injection hole provided in the annular air injection pipe 324. The air enters the oil filter space and forms bubbles that float upward from the inner bottom of the oil filter space. During the process of the bubbles floating up, oil stains adhere to the surface of the bubbles and float together with the bubbles, thereby accelerating the floating of oil stains in the sewage. During the process of the lifting sleeve 302 being driven to rise, the outside air enters the bellows 318 through the first one-way valve 319. It should be noted that when the air is ejected from the second air injection hole provided in the annular air injection pipe 324, the bubbles will impact the angle between the inner convex lifting box 305 and the lifting sleeve 302, preventing the oil stains from accumulating at the angle and being unable to flow.

[0045] 3. Sludge weight classification: The sewage that enters the water pan 401 through the drip valve 322 can be detected by 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 passes through the spiral teeth, the sewage will form a high-speed rotating spiral in the process of entering the conical tube 403. The swirling flow (similar to a vortex) creates centrifugal force through the rotating motion of the sewage, forcing the heavier sediment to move downwards towards the inner wall of the conical tube 403 and be discharged. The lighter sediment, however, is forced upwards along the inner wall of the conical tube 403 by the centrifugal force, flows to the overflow pipe 402, and is discharged from the conical tube 403. This effectively separates the heavier sediment from the lighter sediment in the sewage. In the subsequent treatment of different sewage, the proportion of sewage treatment chemicals (such as in the sewage flocculation stage) can be adjusted according to the different sediment weights in the sludge, thereby reducing the demand for subsequent chemicals and lowering the cost of chemical use.

[0046] 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.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
