Description

[0002] At present, in the process of sewage treatment in domestic urban sewage treatment plants, after the scum on the surface of the anaerobic tank is scraped out by the scraper, except for a small amount of floating objects that are fished out in the scum well, most of the floating oil and floating mud carried by bubbles are returned to the deep well pump room with water, and circulate infinitely. Especially in winter, when the temperature is low, the cohesion of oil pollution increases, and the scum in the anaerobic tank increases, which seriously affects the sensory perception and even affects the water discharge effect of the system.

[0039] The rotating roller 50 is driven by the pulley 54 to rotate at the original position, and the upper adsorption roller 51 is always in contact with the rotating roller 50, that is, the two are always in close contact. When the rotating roller 50 rotates, the power generated by the rotation will drive the adsorption roller 51 in contact with it. Under the influence of the rolling force, the adsorption roller 51 generates a slight up and down movement force under the action of the spring 47. When the rotation speed of the rotating roller 50 changes and the speed increases, it will also drive the contacting adsorption roller 51 to rotate together. At this time, the oil adsorbed and adhered to the surface of the adsorption roller 51 will be scraped off by the rotating roller 50 below under the rotation friction. After the agglomerated oil is scraped off, it will fall into the collection box 4 below after the weight reaches a certain amount. After the weight does not reach the falling weight, it still keeps floating on the water surface, but the scraped oil will be salvaged together with the intercepted impurities.

[0040] Detailed usage and function of this embodiment:

[0041] The device is placed in the anaerobic tank, so that the intercepting grid plate 29 is located at the water surface and connected to the water surface. The driving motor 1 30 is operated, and the motor 1 30 drives the connected threaded rod 21 to rotate. The pulley 1 33 at the end pulls the pulley 2 34 to rotate through the belt 1 35, so that the other threaded rod 21 is also rotated. At this time, the L-shaped frame 22 on the threaded rod 21 will move on the threaded rod 21. Since the end where the L-shaped frame 22 and the threaded rod 21 are connected is an internal thread structure, when the L-shaped frame 22 moves on the threaded rod 21, the L-shaped frame 22 drives the entire scraping device 5 to move in the anaerobic tank. During the movement, the driving motor 25 is operated, and the motor 25 drives the connected The shaft 2 12 of the upper part rotates, and the shaft 2 12 drives the crawler wheels 2 14 on both sides to rotate. The crawler wheels 2 14 will drive the meshing crawler tracks 2 16 on the upper part to move, and the scraper 2 18 on the crawler tracks 2 16 will push the water to one side, and the impurities there will be drawn to one side with the scraper 2 18, and the shaft 2 12 on the other side will drive the pulley 9 69 on the end to rotate, and the pulley 9 69 drives the pulley 10 70 to rotate through the belt 5 71, and the pulley 10 70 drives the pulley shaft 36 to rotate, and the pulley shaft 36 drives the pulley 4 39 and the pulley 5 37 set on the upper part to rotate, and the pulley 4 39 will pull the pulley 3 through the belt 3 41 40 rotates, the pulley three 40 drives the shaft rod 11 to rotate, the shaft rod 11 drives the track wheel 13 to rotate, the track wheel 13 drives the track 15 to move, the track 15 drives the scraper 17 above to move, and the scraper 17 will push the scum together, wherein the scraper 17 pushes toward the direction of the opening 3, and the scraper 2 18 pushes in the opposite direction, the scraper 17 rolls the scum above into the circular guide groove 7 on the right side of the support platform 6, and rolls it downward, and the scraper 2 18 pushes to the left side, and the brought in scum is rolled into the circular guide groove 7 from the upper side of the support platform 6, and as the belt of the circular guide groove 7 works, when the support platform 6 moves to the right, it will roll the inside The floating scum will be carried forward together until it moves to above the opening 3, and the impurities brought in from the inside will enter the collection box 4 from the opening 3. At the same time, when the support platform 6 moves to the right, the interception grid 29 above will intercept the floating scum on it to the right and scrape it to drive it to one side to gather, and the oil stains floating on it will hit the adsorption roller 51, and the adsorption material on the surface of the adsorption roller 51 will adsorb the impacted oil stains. Among them, a miniature refrigerator can be arranged inside the adsorption roller 51 to prompt the adsorption roller 51 to always maintain a certain low temperature state. After hitting the adsorption roller 51, the oil stains are quickly cooled and agglomerated under the action of the low temperature.

[0042] After the pulley five 37 rotates, it drives the pulley six 52 to rotate through the belt two 53, and the pulley six 52 will drive the shaft three 49 to rotate. After the shaft three 49 rotates, it drives the rotating roller 50 to rotate. After the rotating roller 50 rotates, it will cause the surrounding water to roll, and the impurities involved will hit the rotating roller 50 and the adsorption roller 51, and the floating oil contained will be adsorbed on the adsorption roller 51. When the rotating roller 50 below rotates, the rotating roller 50 will also hit the adsorption roller 51. After the adsorption roller 51 is hit, it will produce a certain up and down movement. In addition, when the rotation speed of the rotating roller 50 changes, when the speed increases, it will also drive the adsorption roller at the connection. 51 rotates slightly, and the rotating roller 50 keeps in contact with the surface of the adsorption roller 51 during the rotation process. The oil stains adhered to the surface of the adsorption roller 51 will be scraped off by friction. At the same time, the adsorption roller 51 and the rotating roller 50 also have a certain intercepting and blocking effect, intercepting the impurities that are rolled in. When the rotating roller 50 rotates to the left, it will be opposite to the movement direction of the scraper 17 on the left, causing a vortex to form between the scraper 17 and the two rollers, bringing the introduced impurities downward, and a part of them will be rolled into the collection box 4 below with the rotation force, and the impurities that are not rolled into the collection box 4 below will be gathered there, which is convenient for salvaging them.

[0043] In addition, when the shaft rod 3 49 rotates, it will also drive the pulley 7 54 set at the other end. After the pulley 7 54 rotates, it pulls the pulley 8 63 to rotate through the belt 4 64. The pulley 8 63 drives the shaft rod 4 55 to rotate. The shaft rod 4 55 drives the cam 56 set on the upper part to rotate. After the cam 56 rotates, it will move against the limit top wheel 57 in contact with the side. The limit top wheel 57 moves along the direction of the side wall of the cam 56, prompting the driving arm 59 to move left and right. When the driving arm 59 moves left and right, it will pull the push plate 60 to drag left and right. When the thin plate 61 moves left and right, it will move left and right in the circular guide groove 7. The impurities drawn in will be driven by the left and right forces, causing the flow of the internal water body. When the thin plate 61 is pushed left and right in the circular guide groove 7, the direction of the pushing force is opposite to the movement direction of the scraper 18, so that the flow force direction between the upper frame 10, the lower frame 9 and the two rollers forms an opposing cycle. For example, when the scraper 17 is pushed to the right, the rolling direction of the rotating roller 50 is opposite. When the scraper 18 is pushed to the left and the bottom right side is output, the thin plate 61 will be pushed to the right and hit the inner wall of the circular guide groove 7, and rebound and collide with the water output by the scraper 18. The different forces in the four directions inside collide with each other and circulate. At this time, the impurities driven will be retained by the circulating force generated there, and the driven impurities will be gathered here, thereby facilitating the salvage operation.

[0044] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
