Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated molded assembly-type graded filtration wastewater purification tank. Background Technology

[0002] Wastewater septic tanks are small-scale wastewater treatment facilities suitable for decentralized domestic wastewater treatment. They are mainly used to treat domestic wastewater (such as kitchen wastewater, toilet wastewater, and laundry wastewater) in rural areas, scenic spots, villa areas, and urban-rural fringe areas where pipe networks are insufficient. Their core feature is that through integrated process design, they achieve on-site treatment and compliant discharge of wastewater. They are characterized by small footprint, low construction cost, and simple operation and maintenance, making them an important technical means to solve decentralized wastewater pollution problems.

[0003] However, most existing sewage treatment tanks adopt an integrated structure, which is not convenient for flexible assembly according to actual needs. Moreover, the installation, maintenance and cleaning of the treatment tanks are relatively inconvenient, which increases the difficulty of sewage treatment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an integrated molded assembly-type graded filtration wastewater purification tank.

[0005] The technical solution of this utility model is as follows: an integrated molded and assembled graded filtration sewage purification tank, including a sedimentation tank, an ecological purification tank and a filter tank connected in sequence; the sedimentation tank and the ecological purification tank, and the ecological purification tank and the filter tank are all connected by splicing components, and the outer walls of the sedimentation tank, the ecological purification tank and the filter tank are all provided with docking sleeves that can be movably engaged with the splicing components; an inlet pipe and a first flow pipe are respectively provided at the upper end of the outer wall of the sedimentation tank, and a sewage discharge pipe is provided at the lower end of the outer wall of the sedimentation tank;

[0006] A second flow pipe is installed at the upper end of the outer wall of the ecological purification tank, and a third flow pipe is installed at the lower end of the outer wall of the ecological purification tank. The third flow pipe is connected to the first flow pipe through a first inclined pipe. A packing box is movably attached inside the ecological purification tank and above the third flow pipe. The packing box is filled with coarse sand, ceramsite and gravel from top to bottom.

[0007] A fourth flow pipe is installed at the lower end of the outer wall of the filter tank, and a water purification pipe is installed at the upper end of the outer wall of the filter tank. Hollow fiber membrane and reverse osmosis membrane are sequentially and movably snapped together inside the filter tank and between the fourth flow pipe and the water purification pipe. The fourth flow pipe is connected to the second flow pipe through a second inclined pipe. The heights of the first flow pipe, the second flow pipe, and the water purification pipe decrease sequentially. Control valves are installed on both the first and second inclined pipes.

[0008] Furthermore, the splicing assembly includes a vertical plate and splicing seats respectively disposed on both sides of the vertical plate; the mating sleeve is slidably engaged with the splicing seat, and the mating sleeve is threaded with a locking screw that can engage with the splicing seat;

[0009] Note: In use, the sedimentation tank, ecological purification tank and filter tank are connected in sequence by the snap-fit ​​action of the docking sleeve and the splicing seat, which helps to improve the ease of use of this utility model.

[0010] Furthermore, a guide seat is provided at the bottom of the upright plate, and guide rods are provided on the upper surface of the guide seat and on both sides of the upright plate; the bottom surfaces of the sedimentation tank, the ecological purification tank and the filter tank are all provided with plug-in sleeves that can slide and engage with the guide rods at the corresponding positions.

[0011] Note: When assembling sedimentation tanks, ecological purification tanks, and filter tanks, the connection effect of plug-in sleeves and guide rods helps to improve the positioning accuracy of the connecting sleeves and splicing seats.

[0012] Furthermore, a float is slidably connected inside the sedimentation tank via a sliding rod. A sealing plate capable of blocking the water inlet pipe is installed on the outer wall of the float. A discharge pipe is installed through the float, and a discharge chute is installed at the upper end of the outer wall of the discharge pipe.

[0013] A reagent tank is installed at the top of the sedimentation tank. A through hole is provided on the bottom surface of the reagent tank corresponding to the position of the discharge pipe. A cover plate is provided at the bottom of the reagent tank corresponding to the position of the through hole. The cover plate is slidably engaged with the reagent tank by a vertical rod. A compression spring is sleeved on the vertical rod and abuts against the upper surface of the cover plate.

[0014] Explanation: As the water level inside the sedimentation tank rises, the float rises along the slide bar and eventually blocks the inlet pipe with the sealing plate; at this time, the discharge pipe is inserted into the through hole and pushes the cover plate to move along the upright. The flocculant inside the reagent tank falls into the sedimentation tank through the discharge pipe and reacts with the pollutants in the sewage to form sediment, effectively reducing the difficulty of sewage filtration.

[0015] Furthermore, a stirring paddle is rotatably engaged at the bottom of the sedimentation tank, a first bevel gear is sleeved on the lower end of the outer wall of the stirring paddle, a stirring motor is installed on the outer wall of the sedimentation tank, the output shaft of the stirring motor passes through the sedimentation tank, and a second bevel gear that meshes with the first bevel gear is connected to the end of the output shaft.

[0016] Explanation: The stirring motor drives the second bevel gear to rotate. The meshing action of the second bevel gear and the first bevel gear realizes the rotation of the stirring paddle, which allows the flocculant to be quickly mixed with the sewage under the action of the stirring paddle, thereby improving the flocculation and purification efficiency of the sewage.

[0017] The working principle of this utility model is as follows:

[0018] In use, the sedimentation tank, ecological purification tank, and filter tank are respectively fitted onto the splicing seats on both sides of the upright plate using corresponding connecting sleeves. The connecting sleeves are then locked to the splicing seats using locking screws. The wastewater to be treated is then introduced into the sedimentation tank through the inlet pipe. As the water level in the sedimentation tank rises, the float rises along the sliding rod, eventually causing the sealing plate to block the inlet pipe. At this point, the discharge pipe is inserted into the through hole, pushing the cover plate to move along the upright rod. The flocculant (commercially available product) inside the reagent tank falls into the sedimentation tank through the discharge pipe, and is then stirred by the stirring motor. The second bevel gear rotates, and the meshing action of the second bevel gear and the first bevel gear drives the rotation of the stirring paddle, which mixes the flocculant with the wastewater and causes the pollutants in the wastewater to precipitate. The precipitate is discharged through the sewage pipe. The precipitated wastewater enters the bottom of the ecological purification tank through the first inclined pipe and is filtered through gravel, ceramsite, and coarse sand in sequence. The ecologically purified wastewater enters the filter tank through the second inclined pipe, where it undergoes deep filtration using hollow fiber membranes and reverse osmosis membranes. The purified wastewater is discharged through the clean water pipe for reuse.

[0019] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0020] First, the structure of this utility model is reasonable. The spliced ​​tank structure effectively improves the assembly convenience of the sewage purification tank, while also reducing the use and maintenance costs of the purification tank, thereby improving the convenience of sewage filtration and treatment.

[0021] Secondly, this utility model uses separate tanks to sequentially perform sedimentation pretreatment, ecological interception and purification treatment, and fine filtration treatment on sewage, which effectively improves the purification effect and resource reuse efficiency of sewage.

[0022] Third, this utility model utilizes the free movement of the floating plate to simultaneously achieve the sealing of the inlet pipe and the automatic addition of flocculant, which helps to reduce the operating energy consumption of the sewage treatment tank. Attached Figure Description
