When the pleated filter cloth 15 is installed, the folded part of the pleated filter cloth 15 is supported and tightened by multiple support rods 52, which can prevent the middle part of the pleated filter cloth 15 from being concave and loose during filtration, resulting in a decrease in the filtering effect.

At this time, both ends of the cooling pipe 16 are closed, and the retaining ring 48 is received inside the annular opening 47. The opening 49 on the retaining ring 48 is located inside the annular opening 47, so the connection point between the annular folding chamber 10 and the inside of the return pipe 1 is closed.

[0040] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 9 and Figure 10As shown, the magnetic drainage assembly includes a magnetic ring sleeve 41 and a magnetic ring gasket 40.

[0041] The achieved effect is that firstly the drain pipe 7 is connected with the external negative pressure pipeline, the emulsion containing metal scraps enters the reflux pipe 1 through the hose 4, firstly passes through the buffer cavity 50, enters the annular folding cavity 10 inside through the water inlet hole 27 inside the buffer cavity 50, and the metal scraps are adsorbed through the magnetic ring sleeve 41 and the magnetic ring gasket 40, at the same time, the emulsion flows through the water inlet hole 27 and impacts the spoiler blade 31, thereby driving the rotating shaft 32 to rotate, the rotating shaft 32 drives the bent scraper plate 42 to scrape off the metal scraps adsorbed on the inner wall of the magnetic ring sleeve 41 and the bottom of the magnetic ring gasket 40 when rotating, and collects in the inside of the scrap groove 46, at the same time, the bent scraper plate 42 pushes the contact block 44 into the storage groove 43 when sliding on the inclined surface at the bottom of the contact block 44, so that the sliding sleeve 35 is pushed upwards by the connecting rod 45, at this time, the side opening 38 and the through opening 39 are in communication with each other, the adsorption force is generated under the action of the external negative pressure of the drain pipe 7, the adsorption force can suck out the impurities in the annular bending opening 37 and the annular drain cavity 33, when the metal impurities accumulated between the inner wall of the annular bending opening 37 and the bottom of the magnetic ring gasket 40 are sucked into the annular bending opening 37 under the action of the adsorption force, the metal impurities are discharged, when the top of the bent scraper plate 42 is not in contact with the bottom of the contact block 44, the sliding sleeve 35 is pushed to the bottom of the annular sliding cavity 34 under the elastic force of the lifting spring 36, at this time, the side opening 38 and the through opening 39 are in error with each other, the annular bending opening 37 and the annular drain cavity 33 are reciprocatingly communicated, at this time, the bent scraper plate 42 only scrapes off the scraps on the inner wall of the magnetic ring sleeve 41 and the bottom of the magnetic ring gasket 40.

[0042] Working principle: When using this device, first connect the sewage pipe 7 to the external negative pressure pipe, connect the water inlet pipe 6 to the external cooling water pipe, and connect the water outlet pipe 5 to the water inlet end of the external cooling equipment. When the emulsion containing metal debris enters the return pipe 1 through the hose 4, it first passes through the buffer chamber 50. When it enters the annular folding chamber 10 through the water inlet hole 27 inside the buffer chamber 50, the metal debris is adsorbed by the magnetic ring sleeve 41 and the magnetic ring gasket 40. At the same time, when the emulsion flows through the water inlet hole 27, it will impact the spoiler blade 31, thereby driving the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it will drive the bending scraper 42 to adsorb the inner wall of the magnetic ring sleeve 41 and the bottom of the magnetic ring gasket 40. The metal debris is scraped off and collected in the chip storage groove 46. At the same time, when the bent scraper 42 slides over the bottom inclined surface of the contact block 44, it pushes the contact block 44 to the inside of the receiving groove 43, so that it pushes the sliding sleeve 35 to the top of the annular sliding cavity 34 through the connecting rod 45. At this time, the side port 38 and the through port 39 are connected to each other, and the sewage pipe 7 will generate an adsorption force under the action of the external negative pressure. The adsorption force will suck out the impurities inside the annular groove 37 and the annular sewage cavity 33. When sucking out, the metal impurities accumulated between the annular groove 37 and the inner wall of the magnetic ring sleeve 41 and the bottom of the magnetic ring gasket 40 will break away from the magnetic attraction under the action of the adsorption force and enter the inside of the annular groove 37 for easy discharge. When the tube 1 and the end cover 2 are docked with each other, the multiple contact rods 21 are pressed downward through the annular pressing groove 19, so that the multiple guide holes 26 near the top and bottom of the collar 25 correspond to and communicate with the two ends of the cooling pipe 16 respectively. At this time, the annular water inlet chamber 17 and the annular water outlet chamber 18 are communicated with the two ends of the cooling pipe 16 through the guide holes 26, so that the external cooling water can circulate inside the cooling pipe 16, and then the emulsion entering the return pipe 1 can be cooled. When the contact rod 21 is pressed downward, the push rod 51 will be driven to slide downward, so that the retaining ring 48 can be driven to slide downward. At this time, the multiple openings 49 on the retaining ring 48 are all located between the annular folding chamber 10 and the inside of the return pipe 1. At the connection point, the annular folded cavity 10 is connected to the inside of the return pipe 1 through multiple openings 49. The emulsion cooled by the cooling pipe 16 flows upward from the bottom of the return pipe 1 and is filtered by the folded filter cloth 15 so that the fine metal powder therein can be filtered. The filtered emulsion is filtered again by the filter sleeve 13 on the inside of the folded filter cloth 15 and flows into the sealing ring 12 and the fixed sleeve 11. Finally, the clean emulsion is discharged from the docking pipe 3. When installing the folded filter cloth 15, the folded part of the folded filter cloth 15 is supported and tightened by multiple support rods 52 to prevent the middle part of the folded filter cloth 15 from being concave and loose during filtration, which leads to a decrease in the filtering effect.
