Description

Technical Field

[0001] The present invention relates to the technical field of building drainage and fecal sewage treatment systems, and particularly to an intelligent building drainage and sewage treatment system based on the Internet of Things. Background Art

[0002] The building drainage and fecal sewage treatment system is an important environmental protection facility in buildings. The building drainage and fecal sewage treatment system is usually divided into a building drainage system and a fecal sewage treatment system. Among them, the building drainage system consists of sanitary appliances, drainage pipes, cleaning equipment, ventilation pipes, and local treatment facilities. Its main task is to collect and discharge domestic sewage, wastewater, and rainwater. The fecal sewage treatment system focuses on the treatment of fecal sewage and usually includes septic tanks, which use sedimentation and anaerobic fermentation to remove suspended solids and organic matter. The septic tank is divided into three compartments, and the fecal liquid is treated step by step and finally reaches harmlessness and can be used as fertilizer. Its main tasks are to collect and discharge domestic sewage, wastewater, and rainwater, and to treat fecal sewage.

[0003] The existing building drainage and fecal sewage treatment systems have the following defects:

[0004] 1. Insufficient water seal maintenance. Traditional water seals rely on manual inspection, and the evaporation causes the failure period to be 3 - 6 months, and the odor return complaint rate is as high as 40% (2022 Ministry of Housing and Urban - Rural Development industry report);

[0005] 2. Delayed pipeline dredging. High - rise buildings are manually dredged 4 - 6 times a year on average, and the single - time cost exceeds 2000 yuan. Although some pipelines are equipped with automatic dredging devices, they only rely on pressure sensing, and the false alarm rate exceeds 30%;

[0006] 3. Inefficient septic tanks. Traditional septic tanks need to be manually cleaned every quarter, with low efficiency (processing 1 m 3 requires 2 people / 4 hours); some septic tanks have no solid - liquid separation function, and the resource utilization rate is less than 20%;

[0007] 4. Heavy burden on municipal pipe networks and sewage treatment plants. During the manual cleaning of traditional septic tanks, a large amount of fecal sewage enters the municipal pipe network, resulting in a 15% - 20% increase in the pipe network blockage rate; in order to cope with the additional load, the sewage treatment plant needs to expand the treatment scale (the investment cost increases by 20%) or extend the treatment cycle (the energy consumption increases by 15%).

[0008] Therefore, through beneficial exploration and research, the applicant has found a method to solve the above problems, and the technical solution to be introduced below was generated under this background. Summary of the Invention

Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0048] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0049] Refer to Figure 1 , what is shown in the figure is an intelligent building drainage and sewage treatment system based on the Internet of Things, including a drainage pipeline 100, a plurality of water seal replenishing mechanisms 200, a plurality of horizontal branch pipe dredging mechanisms 300, a horizontal main pipe dredging mechanism 400, an integral intelligent septic tank 500, and a central controller (not shown in the figure).

[0050] The drainage pipeline 100 includes a plurality of drainage vertical pipes 110, a plurality of horizontal branch pipes 120, and a horizontal main pipe 130. A plurality of drainage sewage branch pipes 111 and a plurality of drainage wastewater branch pipes 112 are arranged at intervals along the vertical direction on each drainage vertical pipe 110. A water seal device 113 for isolating odors is arranged on each drainage wastewater branch pipe 112. One end of each horizontal branch pipe 120 is connected to the lower end of the corresponding drainage vertical pipe 110, and the other end is connected to the horizontal main pipe 130.

[0051] The water seal replenishing mechanism 200 is installed at each water seal device 113, and is used to monitor the liquid level of the water seal device 113 and can replenish water into the water seal device according to the liquid level situation. Specifically, refer to Figure 2 and in combination with Figure 1, the water seal water replenishing mechanism 200 includes a liquid level sensor 210, an electromagnetic induction water valve 220, and a water seal water replenishing controller (not shown in the figure). The liquid level sensor 210 is installed inside the water seal device 113 for monitoring the liquid level condition of the water seal device 113. The preset water depth range of the liquid level sensor 210 is 5 mm to 25 mm, and the water depth range at which the liquid level sensor 210 stops replenishing water is 40 mm to 80 mm. The water outlet end of the electromagnetic induction water valve 220 is connected to the corresponding drainage waste water branch pipe 112 through a connecting branch pipe 221, and its water inlet end is connected to the water supply pipeline. The response time of the electromagnetic induction water valve 220 ≤ 0.5 s, and the water replenishing flow rate is 2 L / min. The water seal water replenishing controller is connected to the liquid level sensor 210 and the electromagnetic induction water valve 220 on the one hand, and connected to the central controller on the other hand.

[0052] The dynamic adjustment formula for the water replenishing threshold of the water seal water replenishing mechanism 200: `H_safe = 40 + 0.2×(T - 25) + 0.1×(RH - 60)` (T: temperature in °C, RH: humidity in %). Emergency mode: Continuously for 3 times, when the liquid level sensor 210 monitors that the water depth in the water seal device 113 is lower than the preset range (5 mm to 25 mm), the electromagnetic induction water valve 220 is automatically triggered to replenish water until the water depth reaches the safe range (40 mm to 80 mm) to ensure that the water seal effectively isolates the odor.

[0053] The horizontal main and branch pipe dredging mechanism 300 is installed at each horizontal main and branch pipe 120, and it is used to monitor the blockage condition of the horizontal main and branch pipe 120 and can inject water into the horizontal main and branch pipe 120 according to the blockage condition. Specifically, refer to Figure 2 and combine with Figure 1 , the horizontal main and branch pipe dredging mechanism 300 includes a liquid level sensor 310, an electromagnetic induction water valve 320, and a horizontal main and branch pipe dredging controller (not shown in the figure). The liquid level sensor 310 is installed inside the horizontal main and branch pipe 120 for monitoring the liquid level condition of the horizontal main and branch pipe 120 to judge whether there is a blockage condition. The water outlet end of the electromagnetic induction water valve 320 is connected to the end of the corresponding horizontal main and branch pipe 120 through a connecting branch pipe 321, and its water inlet end is connected to the high-pressure water supply pipeline.

[0054] When the liquid level sensor 310 monitors that the liquid level in the horizontal main and branch pipe 120 exceeds 60%, it controls the electromagnetic induction water valve 320 to inject water into the horizontal main and branch pipe 120. The water injection duration `t = 0.5×(h - 0.6D)`, and the blockage is dredged by using the water pressure. The water injection automatically stops after the liquid level drops.

[0055] The horizontal main trunk pipe dredging mechanism 400 is installed at the horizontal main trunk pipe 130, and it is used to monitor the blockage condition of the horizontal main trunk pipe 130 and can inject water into the horizontal main trunk pipe 130 according to the blockage condition. Specifically, refer toFigure 2 And in combination with Figure 1 The horizontal main pipe dredging mechanism 400 includes a liquid level sensor 410, an electromagnetic induction water valve 420, and a horizontal main pipe dredging controller (not shown in the figure). The liquid level sensor 410 is installed in the horizontal main pipe 130 to monitor the liquid level condition of the horizontal main pipe 130 to determine whether a blockage occurs. The water outlet end of the electromagnetic induction water valve 420 is connected to the end of the horizontal main pipe 130 through a connecting branch pipe 421, and its water inlet end is connected to the high-pressure water supply pipeline. The horizontal main pipe dredging controller is connected to the liquid level sensor 410 and the electromagnetic induction water valve 420 respectively on the one hand, and is connected to the central controller on the other hand.

[0056] When the liquid level sensor 410 detects that the liquid level of the horizontal main pipe 130 exceeds 60%, it controls the electromagnetic induction water valve 420 to inject water into the horizontal main pipe 130. The water injection duration `t = 0.5×(h - 0.6D)` is used to dredge the blockage by water pressure, and the water injection automatically stops after the liquid level drops.

It is used to filter the sewage entering the septic tank 510 and convey the filtered fecal contaminants to a designated area, while the filtered sewage is discharged into the sewage pipe 10 from the sewage outlet 512 of the septic tank 510.

[0060] The extrusion packaging device 530 is arranged in the septic tank 510 and is used to receive the fecal contaminants conveyed by the crawler filter device 520 and extrude the fecal contaminants into a package for storage. Specifically, the extrusion packaging device 530 includes an extrusion packaging bin 531, an extrusion plate 532, and a hydraulic cylinder 533. The extrusion packaging bin 531 is arranged in the septic tank 510. An inlet is provided on the side wall of the extrusion packaging bin 531 and is connected to the discharge end of the crawler filter device 520. The fecal contaminants filtered by the crawler filter device 520 enter the extrusion packaging bin 531 through this inlet. The extrusion plate 532 is horizontally arranged in the extrusion packaging bin 531. The hydraulic cylinder 533 is installed on the top surface of the septic tank 510 and is connected to the septic tank controller 540. The output end of the hydraulic cylinder 533 passes through the septic tank 510 and extends into the extrusion packaging bin 531 and is connected to the extrusion plate 532, and is used to control the extrusion plate 532 to reciprocate vertically. When the fecal contaminants in the extrusion packaging bin 531 reach a certain amount, the hydraulic cylinder 533 drives the extrusion plate 532 to move downward vertically, and extrudes the fecal contaminants in the extrusion packaging bin 531 into a package for storage. After storing a certain amount, the extrusion packaging bin 531 can be opened for cleaning.

[0061] The septic tank controller 540 is installed on the top surface of the septic tank 510.
