DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: an active filtering structure for sewage treatment, comprising a tank body 1, an injection pipe 2 is embedded on the top of the tank body 1, a sealing door 3 is embedded on the right side wall of the tank body 1, a fixing ring 4 is fixedly installed on the bottom of the inner wall of the tank body 1, a mounting ring 5 is attached to the top of the fixing ring 4, a steel mesh is fixedly installed on the bottom of the inner wall of the mounting ring 5, an activated carbon filter cotton 6 is installed inside the mounting ring 5, a retaining ring 7 is tightly attached to the top of the mounting ring 5, and the inner diameter of the retaining ring 7 matches the inner diameter of the mounting ring 5;

[0018] The position of the sealing door 3 is used to pull the mounting ring 5 out of the tank body 1 .

[0019] Rectangular openings 8 are provided at both ends of the outer wall of the tank body 1, an internal threaded ring 9 is screwed on the outer wall of the tank body 1, a connecting rod 10 is integrally formed on the top of the internal threaded ring 9, a connecting ring 11 is integrally formed on the top of the connecting rod 10, an annular groove 12 is provided on the inner wall of the connecting ring 11, a circular ring 13 is rotatably installed in the annular groove 12, and horizontal plates 14 are integrally formed on the left and right ends of the outer wall of the retaining ring 7, and the outer ends of the two horizontal plates 14 pass through the two rectangular openings 8 and are fixedly installed on the left and right ends of the inner wall of the circular ring 13.

[0020] The shape and size of the circular ring 13 match the inner shape and size of the annular groove 12 , and the connecting ring 11 can only rotate with the circular ring 13 as an axis, so that the connecting ring 11 and the circular ring 13 rotate relative to each other.

[0021] Specifically, the inner wall of the connecting ring 11 does not contact the outer wall of the can body 1 .

[0022] Since the inner side wall of the connecting ring 11 does not contact the outer side wall of the tank body 1 , it is possible to avoid obstruction to the rotation of the connecting ring 11 when contacting.

[0023] Specifically, a shunt pipe 15 is fixedly installed at the bottom of the injection pipe 2 . There are multiple shunt pipes 15 , and a nozzle 16 is fixedly connected to the bottom end of the shunt pipe 15 .

[0024] By setting up multiple diversion pipes 15, it is convenient to divert the sewage flowing out of the injection pipe 2 into multiple streams and evenly distribute them on the activated carbon filter cotton 6, thereby increasing the utilization rate of the activated carbon filter cotton 6 and avoiding a stream of sewage frequently falling on one point on the activated carbon filter cotton 6, affecting the filtering effect.

[0025] Specifically, a limiting sliding hole 17 is provided at the top of the horizontal plate 14, and a limiting rod 18 is provided in the limiting sliding hole 17. The upper and lower ends of the limiting rod 18 are respectively fixedly mounted on the inner top wall and bottom wall of the rectangular opening 8, and the inner side wall of the limiting sliding hole 17 slides relatively with the side wall of the limiting rod 18.

[0026] The inner side wall of the limiting sliding hole 17 and the side wall of the limiting rod 18 slide relative to each other to limit the moving track of the retaining ring 7 so that the retaining ring 7 can only move up and down.

[0027] Specifically, the connecting ring 11 is in a circular ring shape and includes an upper ring body 19 and a lower ring body 20 . The top of the lower ring body 20 is fixedly mounted on the bottom of the upper ring body 19 .

[0028] like Figure 3 As shown, by dividing the connecting ring 11 into an upper ring body 19 and a lower ring body 20 , it is convenient to divide the annular groove 12 into two in the early stage, to facilitate the opening of the annular groove 12 , and to facilitate the installation of the ring 13 in the annular groove 12 .

[0029] Specifically, a rubber ring 21 is bonded to the bottom of the retaining ring 7 , and the bottom of the rubber ring 21 is tightly fitted to the top of the mounting ring 5 .

[0030] The rubber ring 21 is provided to increase the sealing effect between the bottom of the retaining ring 7 and the top of the mounting ring 5 .

[0031] Working principle: sewage is injected into the tank body 1 through the injection pipe 2, and the sewage is evenly distributed on the activated carbon filter cotton 6 through multiple diversion pipes 15 for filtration. When the sewage splashes, it can be blocked by the retaining ring 7, and the sewage completely falls on the activated carbon filter cotton 6. When replacing the activated carbon filter cotton 6, open the sealing door 3, rotate the internal thread ring 9 to drive the connecting ring 11, the circular ring 13, the horizontal plate 14 and the retaining ring 7 to move upward, so that the rubber ring 21 is separated from the mounting ring 5, and then the mounting ring 5 is pulled out from the sealing door 3 for replacement.
