[0002] Environmental engineering sewage refers to wastewater generated in various fields such as industry, agriculture, and life, including various organic, inorganic, heavy metal and other pollutants in the wastewater. If these sewage is directly discharged into the environment, it will cause serious pollution to the water, soil, air and other environments, endangering human health and ecological balance.

[0003] The existing related technologies often have the following defects: environmental engineering sewage needs to be filtered during treatment, because when the sewage is discharged into the sedimentation tank, it contains a large amount of garbage and impurities. The sewage is treated by filtering the sewage to meet the emission standards for recycling. The existing filtering method is to weld a filter net at one end of the sewage pipe. Long-term filtration will cause garbage to accumulate in the sewage pipe, causing blockage in the sewage pipe, affecting the effect of sewage filtration.

[0004] Therefore, the utility model provides an environmental engineering sewage filtering and recycling device. Utility Model Content

[0010] Preferably, two guide grooves are provided on the surface of the baffle, the inner walls of the guide grooves are slidably connected to a limiting frame, and the limiting frame is fixedly connected to the surface of the filter box.

[0011] The effect achieved by the above components is that when the baffle moves, the limiting frame will slide along the inner wall of the guide groove, and the limiting frame can limit the moving path of the baffle, thereby preventing the baffle from escaping from the rectangular hole.

[0012] Preferably, support arms are fixedly connected to both sides of the filter box, and a pull ring is fixedly connected to one side of the support arm.

The surface of the drainage pipe 302 is provided with an adjustment structure 4. By setting the adjustment structure 4, it is convenient to adjust the height difference between the sewage and the water surface when it falls into the sedimentation tank 1, thereby avoiding the large-scale impact of the sewage on the water surface in the sedimentation tank 1, causing the sludge at the bottom of the sedimentation tank 1 to turn over, thereby improving the sedimentation effect of the sewage in the sedimentation tank 1.

[0030] The specific settings and functions of the filtering structure 3 and the regulating structure 4 are described in detail below.

[0031] Reference Figure 2 and Figure 3 As shown, in this embodiment: the filter structure 3 includes a rectangular box 301, the rectangular box 301 is connected to the sewage pipe 2, one side of the rectangular box 301 is connected to the drainage pipe 302, and a filter box 303 is placed on the inner wall of the rectangular box 301. A rectangular hole 304 is opened on the surface of the filter box 303, and a bolt 305 is threadedly connected to the surface of the filter box 303. A baffle 306 is slidably connected to the inner wall of the rectangular hole 304. The inner wall of the filter box 303 is rotatably connected to a rotating shaft 307, and the arc surface of the rotating shaft 307 is fixedly connected to a plurality of scrapers 308. The baffle 306 will drive the rotating shaft 307 to rotate with the help of the water flow impact of the sewage, and the rotating shaft 307 will rotate in the filter box 303, and the baffle 306 will slide along the inner wall of the filter box 303. The scraper 308 will drive the filtered garbage to move in the filter box 303, thereby preventing the garbage from being blocked at the filter hole of the filter box 303, thereby improving the efficiency of sewage filtration. Two guide grooves 309 are provided on the surface of the baffle 306. The inner wall of the guide groove 309 is slidably connected to the limit frame 310. The limit frame 310 is fixedly connected to the surface of the filter box 303. When the baffle 306 moves, the limit frame 310 will slide along the inner wall of the guide groove 309. The limit frame 310 can limit the moving path of the baffle 306, thereby preventing the baffle 306 from escaping from the rectangular hole 304. Support arms 311 are fixedly connected to both sides of the filter box 303. A pull ring 312 is fixedly connected to one side of the support arm 311. The movement of the pull ring 312 will drive the movement of the support arm 311. The movement of the support arm 311 will drive the filter box 303 to gradually escape from the rectangular box 301. The pull ring 312 can facilitate the removal of the filter box 303 from the rectangular box 301, thereby facilitating the dumping of the filtered garbage.

[0032] Reference Figure 4 and Figure 5As shown, specifically, the adjustment structure 4 includes a circular tube 41, the inner wall of which is slidably connected to the outer surface of the drain pipe 302, a circular ring 42 is fixedly connected to the surface of the circular tube 41, and a plurality of air bags 43 are fixedly connected to the surface of the circular ring 42. Two arc rings 44 are fixedly connected to the surface of the air bag 43, and a round rod 45 is slidably connected to the inner wall of the two arc rings 44. The round rod 45 is fixedly connected to the surface of the circular ring 42, and the arc ring 44 on the surface of the air bag 43 is sleeved on the surface of the round rod 45. The round rod 45 reaches the position of limiting the air bag 43, thereby avoiding the situation where the position of the air bag 43 is offset due to water flow. The inner wall of the circular tube 41 is provided with a plurality of grooves 46, and the inner wall of the groove 46 is rotatably connected to a plurality of balls 47. When the circular tube 41 moves, the balls 47 will slide on the surface of the drain pipe 302, and the balls 47 will rotate in the groove 46. The balls 47 can reduce the resistance of the circular tube 41 when sliding on the surface of the drain pipe 302, thereby facilitating the movement of the circular tube 41.

[0033] Working principle: when it is necessary to filter the sewage discharged from the sewage pipe 2, first put the filter box 303 into the rectangular box 301, and then turn the bolt 305. The bolt 305 will move in the filter box 303 with the help of the thread, and the bolt 305 will move away from the baffle 306. When the bolt 305 is out of contact with the surface of the baffle 306, pull the baffle 306, and the baffle 306 will slide in the rectangular hole 304. When the baffle 306 moves, it will cause the limit frame 310 to move along the guide The stop frame 310 slides toward the inner wall of the groove 309 to limit the moving path of the baffle 306, thereby preventing the baffle 306 from escaping from the rectangular hole 304. When the baffle 306 moves to a suitable position, the bolt 305 is rotated in the opposite direction, and the bolt 305 is pressed on the surface of the baffle 306, thereby limiting the position of the baffle 306. The sewage in the sewage pipe 2 will pass through the rectangular box 301 and flow into the filter box 303, and the garbage in the sewage will be filtered in the filter box 303. The filtered water will be discharged from the drain pipe 302 into the sedimentation tank 1. When the sewage enters the filter box 303, the baffle 306 will use the water flow of the sewage to drive the shaft 307 to rotate. The rotation of the shaft 307 will rotate in the filter box 303. The baffle 306 will slide along the inner wall of the filter box 303. The scraper 308 will drive the filtered garbage to move in the filter box 303, thereby preventing the garbage from clogging the filter holes of the filter box 303, thereby improving the efficiency of sewage filtration. When the amount of garbage reaches a certain level, the bolt 305 is turned again to disengage the bolt 305 from the baffle 306, and then the baffle 306 is pressed. When the baffle 306 moves to a suitable position, the bolt 305 is turned to fix the baffle 306, and then the pull ring 312 is pulled. The movement of the pull ring 312 will drive the support arm 311 to move. The movement of the support arm 311 will drive the filter box 303 to gradually come out of the rectangular box 301, thereby taking the filter box 303 out of the rectangular box 301 to dump the garbage.

[0034] Before the sewage is discharged from the drain pipe 302 into the sedimentation tank 1, gas is first injected into the airbag 43, and then the arc ring 44 on the surface of the airbag 43 is sleeved on the surface of the round rod 45, and the round rod 45 reaches the position of limiting the airbag 43, thereby avoiding the situation where the position of the airbag 43 is offset due to the water flow. Then the sewage will flow from the drain pipe 302 into the round tube 41 and then into the sedimentation tank 1. When the sewage in the sedimentation tank 1 reaches a certain height, the airbag 43 will float on the water surface, and one end of the round tube 41 will fit on the water surface. When the water level of the sewage in the sedimentation tank 1 gradually rises, the airbag 43 will use its own buoyancy to drive the circular ring 42 to move. The movement of the circular ring 42 will drive the circular tube 41 to slide along the surface of the drain pipe 302. When the circular tube 41 moves, it will cause the ball 47 to slide on the surface of the drain pipe 302, and the ball 47 will rotate in the groove 46. The ball 47 can reduce the resistance of the circular tube 41 when it slides on the surface of the drain pipe 302, thereby facilitating the movement of the circular tube 41.
