[0022] The effect achieved is that the dual-output shaft motor 20 drives the transmission shaft 22 and the stirring shaft 23 to rotate synchronously. When the stirring shaft 23 rotates, it can drive multiple stirring rods 5 to rotate, so that it can mix and stir the water flow transported by the material transport component.

The scraper 49 scrapes off the impurities filtered on the filter port 7 and pushes it to the inside of the temporary storage port 8. When the conveying disc 10 rotates, when the conveying trough 11 rotates to just below the temporary storage port 8, the impurities inside the temporary storage port 8 can fall into the conveying trough 11. When the conveying trough 11 rotates to above the discharge port 12, the impurities inside the conveying trough 11 can flow into the discharge pipe 4 through the discharge port 12 and then be discharged.

[0023] like Figure 3 、 Figure 4 and Figure 8 As shown, the cleaning assembly includes a scraper 49, one end of the scraper 49 is fixed to the outer surface of the drive shaft 22, the bottom of the scraper 49 is in contact with the top of the partition 6, a wedge-shaped groove 50 is provided on one side of the scraper 49, a bending plate 28 is fixed to the inner wall of one side of the bridge sleeve 1, an inverted triangular cavity 47 is provided inside the drive shaft 22 near the top edge, and a plurality of strip-shaped filter ports 48 are provided on the top of the drive shaft 22 at equal distances along the circumferential direction, which penetrate into the inside of the inverted triangular cavity 47.

A lifting spring 45 is fixed between the bottom of the conical block 44 and the inner bottom surface of the conical cavity 43. One end of the pulse injection tube 3 penetrates to the inner top surface of the regulating cavity 35 and is located directly above the conical block 44.

[0026] The effect achieved is that when the transmission shaft 22 rotates, the annular disk 17 and the arc-shaped crescent plate 18 will be driven to rotate. When one end of the lever 46 is in contact with the top of the annular disk 17, the second grid opening 41 on the slide column 30 and the first grid opening 40 on the guide sleeve 39 are connected to each other, the return spring 34 is in a normal state, and the branch opening 37 is offset from the drain opening 38, so at this time the water flow can fill the upper water storage chamber 31 and the lower water storage chamber 36. At the same time, the first through hole 26 is offset from the pulse injection tube 3, and the second through hole 27 is offset from the exhaust pipe 2, so the pulse injection tube 3 and the exhaust pipe 2 are not connected. When the water flow fills the upper water storage chamber 31 and the lower water storage chamber 36, when one end of the lever 46 contacts the arc-shaped crescent plate 18, the lever 46 is pushed upward through the arc-shaped crescent plate 18, thereby bringing The movable slide 30 slides upward.

At the same time, the bottom of the pulse injection tube 3 is inserted into the top surface of the conical cavity 43, so when the pulse injection tube 3 is injected, pressure is generated to press the conical block 44 downward. At this time, the material inside the pulse injection tube 3 can flow into the conical cavity 43, and then flow into the inside of the inner constraint ring 32 through the side flow channel 42 to mix with the water flow in the upper water storage chamber 31. The water inside the upper water storage chamber 31 and the lower water storage chamber 36 is discharged through the drain opening 38 and the branch opening 37.

[0027] Working principle: When using this device, the wastewater is injected into the inside of the bridge sleeve 1 from one end of the bridge sleeve 1. Inside the bridge sleeve 1, the larger impurities in the wastewater are first filtered through the filter port 7 on the partition 6. The dual-output shaft motor 20 drives the transmission shaft 22 and the stirring shaft 23 to rotate synchronously. When the stirring shaft 23 rotates, it can drive multiple stirring rods 5 to rotate, so that it can mix and stir the water flow after the material transport component is transported. When the transmission shaft 22 rotates, it can drive the cleaning component to remove the impurities filtered by the filter port 7 and transport it intermittently. At the same time, when the transmission shaft 22 rotates, it can also drive the material transport component to work intermittently. When the transmission shaft 22 rotates, it will drive the scraper 49 conveyor disc 10 to rotate. The scraper 49 scrapes off the impurities filtered on the filter port 7 and pushes it to the temporary storage port. 8, when the conveying disc 10 rotates, when the conveying trough 11 rotates to the bottom of the temporary storage port 8, the impurities inside the temporary storage port 8 can fall into the conveying trough 11, and when the conveying trough 11 rotates to above the discharge port 12, the impurities inside the conveying trough 11 can flow into the discharge pipe 4 through the discharge port 12, and then be discharged. When the scraper 49 scrapes the impurities on the filter port 7, since a plurality of strip filter ports 48 are provided on the transmission shaft 22 and an inverted triangular cavity 47 is provided inside, when the water flow inside the bridge sleeve 1 enters the inverted triangular cavity 47 through the strip filter ports 48, it will be discharged from the beam channel 15 at the bottom of the inverted triangular cavity 47. Since the opening area is larger when the water flow enters the inverted triangular cavity 47, and the opening is smaller when it is discharged from the beam channel 15, the water flow will have a certain A certain pressure is boosted, and the boosted water flows from the beam channel 15 through the side channel 13 to the inside of the return channel 14, and finally is discharged upward from the bottom of the filter port 7, thereby blowing out the impurities inside the filter port 7, which is convenient for scraping with the scraper 49. At the same time, a wedge-shaped groove 50 is provided at the bottom of one side of the scraper 49, which can push the scraped impurities to the middle part for collection, so as to push the impurities into the temporary storage port 8. When the transmission shaft 22 rotates, it will drive the annular disk 17 and the arc-shaped crescent plate 18 to rotate. When one end of the lever 46 is in contact with the top of the annular disk 17, the second grid port 41 on the slide column 30 and the first grid port 40 on the guide sleeve 39 are connected to each other, the reset spring 34 is in a normal state, and the branch port 37 is offset relative to the drain port 38, so at this time the water flow can go upward. The water storage chamber 31 and the lower water storage chamber 36 are filled. At the same time, the first through hole 26 is offset from the pulse injection tube 3, and the second through hole 27 is offset from the exhaust pipe 2. Therefore, the pulse injection tube 3 and the exhaust pipe 2 are not connected. When the water fills the upper water storage chamber 31 and the lower water storage chamber 36, when one end of the lever 46 contacts the arc-shaped crescent plate 18, the lever 46 is pushed upward by the arc-shaped crescent plate 18, thereby driving the slide column 30 to slide upward. At this time, the second grid opening 41 on the slide column 30 is offset from the first grid opening 40 on the guide sleeve 39, the branch opening 37 and the drain port 38 are connected to each other, the first through hole 26 and the pulse injection tube 3 are connected to each other, and the second through hole 27 and the exhaust pipe 2 are connected to each other, thereby preventing the generation of a closed volume in the upper water storage chamber 31 during drainage.This prevents the water from being discharged. At the same time, the bottom of the pulse injection tube 3 is inserted into the top surface of the tapered cavity 43. Therefore, when the pulse injection tube 3 is injecting material, pressure is generated, pressing the tapered block 44 downward. At this time, the material inside the pulse injection tube 3 can flow into the tapered cavity 43, and then flow into the inner confinement ring 32 through the side flow channel 42 to mix with the water in the upper water storage chamber 31. The water in the upper water storage chamber 31 and the lower water storage chamber 36 is discharged through the drain port 38 and the branch port 37.
