[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a technical solution, such as Figure 1-Figure 2 As shown; a scum collecting device for a sewage treatment pool comprises a triangular bracket 1, which is installed above the wall at one end of the sewage treatment pool, and also comprises: an L-shaped bracket 11, which is installed on one side below the triangular bracket 1 and is located outside the sewage treatment pool, and a scum collecting box 111 is installed on it; a collecting inclined baffle 12, which is installed on the inclined surface of the triangular bracket 1, and its lower end is inserted into the sewage treatment pool and inserted into the sewage, its upper end is connected to the scum collecting box 111, and a triangular filling box 121 is installed below it, and the triangular filling box 121 is located in the sewage treatment pool and filled between the sewage and the collecting inclined baffle 12.

[0029] In the embodiment of the utility model, the setting of the triangular bracket 1 can facilitate the installation of the scum collection box 111 and the installation of the collecting inclined baffle 12, so that the device can span one end of the sewage treatment tank, and through the inclination of the collecting inclined baffle 12, the scum can be quickly scraped out of the sewage treatment tank, so as to facilitate the collection of the scum.

[0030] In the embodiment of the utility model, the L-shaped bracket 11 is used to facilitate the installation of the scum collection box 111, and the scum collection box 111 can be hung outside the sewage treatment tank, thereby facilitating the collection of scum.

[0031] In the embodiment of the utility model, the triangular filling box 121 can be used to block the lower end of the collecting inclined baffle 12 to avoid a gap between the lower end and the sewage, which causes scum to accumulate under the collecting inclined baffle 12 and affect the collection of scum.

[0032] The circulating scraping collection mechanism 2 is arranged above the sewage treatment tank and located above the collecting inclined baffle 12, and includes: a fixed frame 21, which is arranged above the walls on both sides of the sewage collection tank and fixedly connected to the sewage collection tank through anchor bolts. There are multiple fixed frames 21, on which a wire rope pulley 211 is movably installed, and an annular wire rope 212 is mounted on the wire rope pulley 211. The annular wire rope 212 is distributed in an inverted right-angled trapezoid on both sides above the sewage collection tank; a fixed gear rod 22, which is arranged above the sewage collection tank and evenly arranged between the two annular wire ropes 212, and fixed short shafts 221 are installed at both ends of the fixed short shaft 221, and one end of the fixed short shaft 221 is movably mounted on a fixed clamp seat 222, a wire rope groove 223 is opened on the fixed clamp seat 222, a fixed clamp block 224 is arranged in the wire rope groove 223, and a fastening bolt 225 is threadedly installed on one side of the fixed clamp seat 222, and the fastening bolt 225 is movably connected to the fixed clamp block 224.

[0033] In the embodiment of the utility model, by using the setting of the fixed frame 21, a wire rope wheel 211 can be set on both sides above the sewage treatment tank, and by installing an annular wire rope 212 thereon, the annular wire rope 212 can be made to reciprocate, and then the floating scraper box 231 is used to scrape the scum.

[0034] In the embodiment of the utility model, the annular steel wire rope 212 is distributed in an inverted right-angled trapezoidal pattern above the sewage treatment tank. On the one hand, the horizontal level of its lower end can be used to enable the floating scraper box 231 to scrape the scum on the upper surface of the sewage. Then, through the inclined surface of the right-angled trapezoidal pattern, the floating scraper box 231 can scrape the scum onto the collecting inclined baffle 12 and move along the collecting inclined baffle 12, so that the scum can be quickly scraped into the scum collection box 111, thereby improving the collection efficiency of the scum and reducing the operation workload of the staff. At the same time, it has a simple structure, is easy to use, and has a low cost.

[0035] In the embodiment of the utility model, by utilizing the rotational cooperation between the fixed baffle 22 and the fixed clamp seat 222, the floating scraper box 231 can always be in a vertical state by utilizing gravity during use, thereby ensuring smooth scraping of scum. At the same time, by utilizing the cooperation between the fixed clamp seat 222 and the fixed clamp block 224, the fixed baffle 22 can be quickly connected to the annular wire rope 212, making the installation of the device more convenient and quick.

[0036] The vertical baffle 23 is installed at the center of the lower surface of the fixed baffle rod 22, and a floating scraper box 231 is installed at its lower end. The upper end of the floating scraper box 231 is square and the lower end is an isosceles trapezoid. A certain amount of weighted water 232 is filled inside the floating scraper box 231.

[0037] In the embodiment of the utility model, the floating scraper box 231 is arranged, and its lower end is an isosceles trapezoid, which can reduce the resistance of its movement in the sewage and avoid the sewage overflow during its movement. At the same time, the buoyancy of the floating scraper box 231 itself can be utilized to enable it to float above the sewage, thereby facilitating the scraping of the scum. In addition, the weighting of the weighting water 232 can ensure that the floating scraper box 231 can fully drive the scum to move, thereby ensuring the smooth scraping of the scum.

[0038] As a scum collection device for a sewage treatment pool of the utility model, the isosceles trapezoidal inclined surface at the lower end of the floating scraper box 231 has the same inclined angle as the collecting inclined baffle 12 and is in sliding contact with it; this can ensure that the floating scraper box 231 can push the scum along the collecting inclined baffle 12 into the scum collection box 111 to avoid scum leakage.

[0039] As a scum collecting device for a sewage treatment pool of the utility model, the floating scraper box 231 is weighted by the weighted water 232 so that its lower end is immersed in the sewage in the sewage treatment pool, thereby ensuring that the floating scraper box 231 has sufficient strength to scrape the scum.

[0040] As a scum collecting device for a sewage treatment pool of the utility model, the upper end of the floating scraper box 231 floats above the sewage in the sewage treatment pool by its own buoyancy, so that the scum can be scraped off smoothly without causing the sewage to overflow from the sewage treatment pool.

[0041] As a scum collecting device for a sewage treatment pool of the utility model, the annular steel wire rope 212 is clamped on the fixing clamp seat 222 by a fixing clamp block 224; it can facilitate the connection between the floating scraper box 231 and the annular steel wire rope 212, and at the same time enable the annular steel wire rope 212 to move smoothly.

[0042] As a scum collection device for a sewage treatment pool of the utility model, the wire rope wheel 211 located at the top of the collecting inclined baffle 12 is connected to the driving mechanism, so that it drives two ring-shaped wire ropes 212 to rotate slowly; the driving mechanism can be used to make the wire rope wheel 211 drive the ring-shaped wire rope 212 to rotate slowly, thereby collecting the scum.

[0043] When the utility model is used specifically, the device is installed on the sewage treatment tank. After the device is installed, the driving mechanism is connected to the wire rope wheel 211 at the top of the collecting inclined baffle 12, and its operation is controlled;

[0044] As the wire rope wheel 211 rotates, the wire rope wheel 211 drives the annular wire rope 212 to rotate, so that the annular wire rope 212 drives the fixed clamp seat 222 to move, and then the fixed short shaft 221 drives the fixed lever 22 to move, so that the fixed lever 22 drives the floating scraper box 231 to move slowly through the vertical baffle 23;

[0045] The floating scraper box 231 uses its own weight and the gravity of the weighted water to keep it in a vertical state all the time. As the circular steel wire rope 212 continues to rotate, the floating scraper box 231 gradually moves to the top of the sewage in the sewage treatment tank, and then its lower end is partially immersed in the sewage. At the same time, it uses its own buoyancy to float above the sewage. As the circular steel wire rope 212 rotates, the floating scraper box 231 moves horizontally in the sewage treatment tank, and the floating scum on the upper surface of the sewage is scraped away by the movement of the floating scraper box 231.

[0046] As the floating scraper box 231 moves to the collecting inclined baffle 12, the scum also moves to the collecting inclined baffle 12 with the floating scraper box 231, and then the floating scraper box 231 moves along the collecting inclined baffle 12 through the sliding contact between the inclined surface of the floating scraper box 231 and the collecting inclined baffle 12, and pushes the scum to move upward, and finally makes the scum fall into the scum collecting box 111, and then the floating scraper box 231 moves to the sewage treatment tank again with the rotation of the ring-shaped steel wire rope 212, so as to cyclically scrape the scum in the sewage treatment tank;

[0047] The floating scraper boxes 231 evenly distributed are used to reciprocately scrape the scum on the sewage surface, thereby effectively improving the collection efficiency of the scum and reducing the workload of the staff.

[0048] When the device is implemented, since the two wire rope wheels 211 at the top of the collecting inclined baffle 12 are connected by a driving shaft, when the floating scraper box 231 moves to this place, the floating scraper box 231 can adjust the angle by using the movable connection between the fixed gear rod 2 and the fixed clamp seat 222, so that it can cross over the driving shaft by rotation, ensuring the smooth movement of the device. At the same time, the shape of the floating scraper box 231 can also adopt a diamond structure, which is convenient for the floating scraper box 231 to cross over the driving shaft.
