Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage sedimentation device for environmental protection projects. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

[0003] There are a large number of suspended solids in sewage. Due to their small particles, it is difficult to remove them by normal filtration. At this time, the sedimentation method is adopted. A flocculant that promotes the flocculation of suspended solids is added to the sewage to make the suspended solids flocculate in large quantities and separate from the sewage. Then, the flocculated matter is removed, and the content of suspended solids in the sewage can be reduced. Based on this, a sewage sedimentation device for environmental protection projects is proposed to carry out sedimentation treatment on sewage. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a sewage sedimentation device for environmental protection projects, effectively solving the deficiencies of the prior art.

[0005] To achieve the above purpose, an embodiment of one aspect of the utility model provides a sewage sedimentation device for environmental protection projects, including a treatment tank and a support frame placed side by side with it. A horizontally rotatable mounting frame is installed at the bottom end of the treatment tank. A plurality of mud stirring rods are installed at the top end of the mounting frame. A plurality of stirring frames are installed at the edge of the top surface of the mounting frame. Three control valves are installed on the outer wall of the treatment tank from bottom to top. A top cover is installed on the top surface of the treatment tank. A vertically movable chemical adding pipe is installed in the middle of the top surface of the top cover. The bottom end of the chemical adding pipe is located between a plurality of stirring frames. A plurality of discharge ports are installed at the bottom end of the chemical adding pipe. A medicine storage tank is installed on the top surface of the support frame, and a first liquid pump is arranged on one side of it. The output end of the first liquid pump is connected to the chemical adding pipe through a hose.

[0006] Preferably, the outer shape of the bottom end of the treatment tank is conical. Three legs are arranged at the edge of the bottom end of the treatment tank. A first motor is installed on the bottom surface of the treatment tank, and its output end is fixedly connected to the mounting frame. The three legs in this scheme facilitate the stable support of the treatment tank. At the same time, when the first motor is energized and operates, it drives the mounting frame and a plurality of stirring frames to rotate in a circle, so that the medicine and sewage are evenly stirred. At the same time, the conical structure at the bottom end of the treatment tank facilitates the sediment to deposit towards the middle. After discharging the floating matter and sewage at the top, the plurality of mud stirring rods facilitate the stirring of the sediment to facilitate the discharge of the sediment from the control valve.

[0007] Preferably, according to any of the above solutions, the tops of the plurality of stirring frames all extend upward, and the plurality of stirring frames are circumferentially and arrayedly distributed on the top surface of the mounting frame. This solution facilitates the circumferential rotation of the stirring frames along with the mounting frame, thereby driving the sewage to rotate inside the treatment tank. When the medicament is sprayed out from the plurality of discharge ports, it is then facilitated to rotate along with the sewage, facilitating the uniform mixing of the medicament and the sewage, and facilitating the flocculation of the suspended matter in the sewage.

[0008] Preferably, according to any of the above solutions, a second motor is installed in the middle of the top surface of the upper cover, and a gear is installed at its output end. A rack meshing with the gear is installed on the outer wall of the dosing pipe. This solution facilitates the energization and operation of the second motor, and the forward and reverse rotation, so that the gear and the rack rotate relative to each other, driving the dosing pipe to perform cyclic up and down movements in the vertical direction, ensuring that the medicament is discharged into sewage at different depths, and facilitating flocculation.

[0009] Preferably, according to any of the above solutions, a feed pipe is installed on one side of the top surface of the upper cover, and a second liquid pump is installed at one end thereof. An air outlet is installed on the other side of the top surface of the upper cover. This solution facilitates the energization and operation of the second liquid pump to pump the external sewage into the treatment tank. At the same time, the upper cover covers the top end of the treatment tank, and the air outlet facilitates the timely discharge of the air inside the treatment tank, facilitating the entry of sewage. At the same time, when the sewage is discharged, it is then facilitated for the external air to enter the treatment tank along the air outlet.

[0010] Preferably, according to any of the above solutions, the plurality of discharge ports are circumferentially and arrayedly distributed at the top end of the dosing pipe, and the plurality of discharge ports are respectively arranged obliquely upward, horizontally and obliquely downward. By using this solution, it is facilitated for the medicament to be discharged obliquely upward, horizontally and obliquely downward along the discharge ports respectively. At the same time, along with the vertical movement of the dosing pipe, the medicament can be discharged into sewage at different depths, making the medicament and the sewage evenly mixed.

[0011] The utility model has the following advantages:

[0012] 1. For this sewage sedimentation device for environmental protection projects, by setting a treatment tank, an upper cover and a medicine storage tank, a dosing pipe capable of vertical movement is arranged in the middle of the upper cover. At the same time, a mounting frame and stirring frames are installed inside the treatment tank. By energizing and operating the first liquid pump, the medicament is added into the treatment tank. At the same time, by energizing and operating the first motor, the plurality of stirring frames are driven to rotate circumferentially, so that the medicament and the sewage are evenly mixed and then left to stand. By controlling the three control valves, the floating matter, sewage and sediment are respectively discharged. The overall structure is simple, the design is reasonable, and it is convenient for popularization and use.

[0020] As Figures 1 to 4 shown, a sewage sedimentation device for an environmental protection project includes a treatment tank 1 and a support frame 2 placed side by side therewith. A rotatable mounting frame 16 for horizontal rotation is installed at the bottom end of the treatment tank 1. A plurality of mud stirring rods 15 are installed at the top end of the mounting frame 16. A plurality of stirring frames 14 are installed at the edge of the top surface of the mounting frame 16. Three control valves 11 are installed on the outer wall of the treatment tank 1 from bottom to top. An upper cover 10 is installed on the top surface of the treatment tank 1. A chemical dosing pipe 8 capable of moving vertically is installed in the middle of the top surface of the upper cover 10. The bottom end of the chemical dosing pipe 8 is located between a plurality of stirring frames 14. A plurality of discharge ports 13 are installed at the bottom end of the chemical dosing pipe 8. A drug storage tank 5 is installed on the top surface of the support frame 2. A first liquid pump 6 is arranged on one side thereof. The output end of the first liquid pump 6 is connected to the chemical dosing pipe 8 through a hose.

[0021] The outer shape of the bottom end of the treatment tank 1 is conical. There are three legs provided at the edge of the bottom end of the treatment tank 1. A first motor 12 is installed on the bottom surface of the treatment tank 1, and its output end is fixedly connected to the mounting frame 16. As an alternative technical solution of the present invention, the three legs facilitate the stable support of the treatment tank 1. At the same time, when the first motor 12 is powered on and operates, it drives the mounting frame 16 and multiple stirring frames 14 to rotate in a circle, so that the medicament and the sewage are evenly stirred. At the same time, the conical structure at the bottom end of the treatment tank 1 facilitates the sediment to deposit towards the middle. After discharging the floating matter and sewage at the top, the sediment can be stirred to a certain extent by multiple mud stirring rods 15, which is convenient for the sediment to be discharged from the control valve 11.

[0022] The tops of the multiple stirring frames 14 all extend upward, and the multiple stirring frames 14 are circumferentially arrayed on the top surface of the mounting frame 16. As an alternative technical solution of the present invention, this facilitates the stirring frames 14 to rotate in a circle along with the mounting frame 16, thereby driving the sewage to rotate inside the treatment tank 1. When the medicament is sprayed out from the multiple discharge ports 13, it is then facilitated to rotate along with the sewage, which is convenient for the medicament and the sewage to be evenly mixed and for the suspended matter in the sewage to coagulate.

[0023] A second motor 17 is installed in the middle of the top surface of the upper cover 10, and a gear 7 is installed at its output end. A rack 9 meshing with the gear 7 is installed on the outer wall of the chemical addition pipe 8. As an alternative technical solution of the present invention, this facilitates the second motor 17 to be powered on and operate, and rotate forward and backward, so that the gear 7 and the rack 9 rotate relative to each other, driving the chemical addition pipe 8 to move up and down in a cycle in the vertical direction, ensuring that the medicament is discharged into the sewage at different depths, which is convenient for coagulation.

[0024] A feed pipe 3 is installed on one side of the top surface of the upper cover 10, and a second liquid pump 4 is installed at one end of it. An air outlet is installed on the other side of the top surface of the upper cover 10. As an alternative technical solution of the present invention, this facilitates the second liquid pump 4 to be powered on and operate to pump the external sewage into the treatment tank 1. At the same time, the upper cover 10 covers the top end of the treatment tank 1, and the air outlet facilitates the timely discharge of the air inside the treatment tank 1, which is convenient for the sewage to enter. At the same time, when the sewage is discharged, it is then facilitated for the external air to enter the treatment tank 1 along the air outlet.

[0025] The multiple discharge ports 13 are circumferentially arrayed at the top end of the chemical addition pipe 8, and the multiple discharge ports 13 are respectively arranged obliquely upward, horizontally, and obliquely downward. As an alternative technical solution of the present invention, this facilitates the medicament to be discharged obliquely upward, horizontally, and obliquely downward along the discharge ports 13 respectively. At the same time, with the vertical movement of the chemical addition pipe 8, the medicament can be discharged into the sewage at different depths, so that the medicament and the sewage are evenly mixed.

[0026] For the sewage sedimentation device of this environmental protection project, the following steps are required during use:

[0027] 1) During use, the second liquid pump 4 is powered on and operates to pump sewage through the feed pipe 3 into the interior of the treatment tank 1;

[0028] 2) The first motor 12 is powered on and operates to drive the mounting frame 16 and multiple stirring frames 14 to rotate in a circular motion;

[0029] 3) The first liquid pump 6 is powered on and operates to pump the medicament in the medicine storage tank 5 into the interior of the medicine adding pipe 8 and discharge it into the sewage from multiple discharge ports 13;

[0030] 4) After stirring for a certain period of time, the first motor 12 stops rotating, and the sewage in the treatment tank 1 is allowed to stand still;

[0031] 5) Control the three control valves 11 to open respectively to discharge the floating matter, sewage and sediment respectively.

[0032] In summary, when the user uses it, by setting the treatment tank 1, the upper cover 10 and the medicine storage tank 5, a medicine adding pipe 8 capable of vertical movement is provided in the middle of the upper cover 10. At the same time, a mounting frame 16 and stirring frames 14 are installed inside the treatment tank 1. By powering on and operating the first liquid pump 6, the medicament is added into the interior of the treatment tank 1. At the same time, the first motor 12 is powered on and operates to drive multiple stirring frames 14 to rotate in a circular motion, so that the medicament and sewage are evenly mixed and then allowed to stand still. By controlling the three control valves 11, the floating matter, sewage and sediment are discharged respectively. The overall structure is simple, the design is reasonable, and it is convenient to promote and use. By setting the upper cover 10, a second motor 17 is installed in the middle of its top surface, and a gear 7 is installed at its output end.
