[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 shown, a sewage purification device for a municipal sewage pipe network includes: a filtering mechanism 1 for filtering sundries; a diverting pipe 2 communicated with the filtering mechanism 1, and a solenoid valve 21 is provided on the diverting pipe 2; a sedimentation tank 3 communicated with the branch end of the diverting pipe 2; a treatment tank 4 is provided in the sedimentation tank 3; a chemical adding mechanism 5 provided on the top of the treatment tank 4; a stirrer 6 provided in the treatment tank 4; and a collecting pipe 7 communicated with the rear end of the sedimentation tank 3.

[0025] After the sewage in the municipal pipe network enters this device, it first enters the filtering mechanism 1 to separate large pieces of garbage from the sewage. As Figure 2 shown, the filtering mechanism 1 includes a filter box 11 and a filter screen 12. The filter box 11 is provided with a first water inlet hole 111 and a first water outlet hole 112. The filter screen 12 is L-shaped, and the filter screen 12 and the side wall of the filter box 11 surround the first water inlet hole 111. The first water inlet hole 111 is in the upper half of the side wall of the filter box 11, and the first water inlet hole 111 is connected to the municipal sewage pipe network. After the sewage enters the filter box 11 from the first water inlet hole 111, it all passes through the filter screen 12. The filter screen 12 blocks large pieces of garbage. The top of the filter box 11 adopts a flip design, and the filter screen 12 can be exposed through the flip, which is convenient for cleaning the garbage in the filter screen 12. The first water outlet hole 112 is located on the side wall of the filter box 11 opposite to the first water inlet hole 111, and the first water outlet hole 112 is located in the lower part of the side wall, which is convenient for the filtered municipal wastewater to flow out into the diverting pipe 2.

[0026] The main pipe end of the diverting pipe 2 is communicated with the first water outlet hole 112. The diverting pipe 2 is provided with two branches, and the solenoid valves 21 are provided on the branch ends of the diverting pipe 2. The two solenoid valves 21 control the branch pipes into which the sewage flows through opening and closing, and further control the sewage to enter the sedimentation tank 3.

[0027] There is a second water inlet hole at the front end of the sedimentation tank 3. The second water inlet hole is communicated with the shunt pipe 2. After the sewage enters the sedimentation tank 3, it first flows into the treatment tank 4.

[0028] As Figure 3 shown, the treatment tank 4 includes a top cover 41, a limiting plate 42, a rotating door 43, a winding machine 44 and a sealing door 45. The top cover 41 is arranged on the top of the sedimentation tank 3. The rotating door 43 is rotatably connected to the front end of the top cover 41. The rotating door 43 is opened by hydraulic force. In other embodiments, the opening and closing angle of the rotating door 43 is controlled by a motor. The limiting plate 42 is arranged at the bottom of the sedimentation tank 3. The sealing door 45 is slidably connected to the top cover 41. The winding machine 44 is connected to the top of the sealing door 45.

[0029] The limiting plate 42 is arranged in front of the rotating door 43. The top of the limiting plate 42 is located above the bottom of the rotating door 43. When the rotating door 43 is vertical, it fits with the limiting plate 42. The limiting plate 42 restricts the rotation of the rotating door 43 in the direction of the shunt pipe 2. After the water passes through the rotating door 43, the rotating door 43 closes and the water cannot flow back. If the sealing door 45 is also in the closed state at this time, the sewage is restricted in the treatment tank 4. After the sealing door 45 is opened, the sewage flows out of the treatment tank 4.

[0030] The sealing door 45 penetrates through the top cover 41 and is slidably connected to the side wall of the sedimentation tank 3. When the winding machine 44 is in the lowered state, the sealing door 45 fits with the side wall and the bottom edge of the sedimentation tank 3 under the action of gravity to prevent water from flowing out. When discharging water, the winding machine 44 is started to pull the sealing door 45 upward, so that the sealing door 45 slides upward and the water flows out from the sealing door 45.

[0031] After the sewage is restricted in the treatment tank 4, the sewage is treated and purified by the dosing mechanism 5. The dosing mechanism 5 includes a medicine storage box 51, a sieve 52 and a vibrator 53. The medicine storage box 51 is arranged on the top cover 41. There is a medicine outlet at the front end of the medicine storage box 51. There is also a notch on the top cover 41. The notch is in front of the medicine outlet. Medicines for purifying water quality are placed in the medicine outlet box. The medicines come out from the medicine outlet and fall into the treatment tank 4 for sewage purification. The bottom of the medicine storage box 51 is inclined towards the medicine outlet to facilitate the movement of the medicines towards the medicine outlet. The sieve 52 is arranged on the side wall of the medicine outlet. The sieve 52 is used to evenly scatter the medicines into the treatment tank 4 to avoid a large amount of medicines entering the treatment tank 4 at the same time. The vibrator 53 is arranged on the side wall of the medicine storage box 51. By starting the vibrator 53, the medicine storage box 51 is vibrated, further driving the medicines in the medicine outlet box to move along the inclined direction towards the medicine outlet, achieving the effect of automatic dosing. When the vibrator 53 vibrates, it will indirectly drive the sewage in the treatment tank 4 to vibrate together, accelerating the reaction between the medicines and the sewage and accelerating the sewage purification speed.

[0032] The top of the agitator 6 penetrates through the top cover 41, and the agitator 6 is driven by a motor 61. The agitator 6 agitates the sewage, further causing the sewage and the drug to react, causing the impurities in the sewage to coagulate into flocculent precipitates, and purifying the water body.

[0033] When the sewage has reacted with the drug in the treatment tank 4, the sealed door 45 is opened to allow the treated sewage to continue to move forward in the sedimentation tank 3. A recessed area is provided at the front end of the sedimentation tank 3, and a garbage tank 31 is provided in the recessed area. The garbage tank 31 is detachably connected to the recessed area. The sewage forming flocculent precipitates decelerates in the recessed area, and part of the flocculent precipitates sink into the garbage tank 31. A slope 32 is provided behind the recessed area, and the slope 32 blocks the progress of the flocculent substances, causing the flocculent substances to fall into the garbage tank 31. A collecting pipe 7 is provided above the slope 32, and the collecting pipe 7 is connected to the rear end of the sedimentation tank 3 through a second water outlet hole. The collecting pipe 7 sends the sewage to the next link of the municipal pipe network.

[0034] The top of the garbage tank 31 is also provided with a flip cover for easy access to the garbage tank 31.

[0035] When the treatment tank 4 purifies water, it takes a certain period of time for the drug to act. Therefore, the shunt pipe 2 connects the two sedimentation tanks 3. When the treatment tank 4 of one sedimentation tank 3 purifies water, the other treatment tank 4 discharges the purified water into the collecting pipe 7, enabling drug precipitation to occur even when the sewage treatment is carried out continuously.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
