Description

Technical Field

[0001] This utility model application relates to the field of sewage treatment equipment technology, specifically an integrated sewage closed lift pump station. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. According to the source of wastewater, wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is the wastewater generated in daily life.

[0003] The existing sewage treatment method involves transporting sewage into a pump well, where workers then activate a sewage pump to remove the sewage. However, the time it takes for sewage to flow into the pump well is not fixed, requiring workers to activate the pump in a timely manner to remove the sewage. Otherwise, sewage may accumulate inside the pump well or even backflow. In addition, the existing pump wells are dug underground, which makes it easy for sewage to seep into the ground, affecting the surrounding environment and causing odors to overflow. Summary of the Invention

[0004] To address the problem that existing sewage treatment methods involve transporting sewage into a pump well and then having workers activate a sewage pump to remove the sewage, which is subject to unpredictable flow times, requiring timely pumping to prevent sewage buildup and backflow, this invention provides an integrated, sealed sewage lift pump station to solve these issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated closed-loop sewage lifting pump station includes a main body of the sewage pump station. The top surface of the main body of the sewage pump station has a pump station inlet and outlet. A sewage inlet pipe is provided on one side of the main body of the sewage pump station. Several sewage pump bodies are installed inside the main body of the sewage pump station. Each sewage pump body is connected to a sewage discharge pipe through a flange. The top surface of each sewage discharge pipe is connected to a sewage outlet pipe. A shut-off valve is provided at the end of each sewage discharge pipe near the sewage outlet pipe. A water level detector body corresponding to the number of sewage pump bodies is provided inside the main body of the sewage pump station near the sewage inlet pipe. Each water level detector body is electrically connected to a different sewage pump body.

[0007] Furthermore, a maintenance platform is fixed in the middle of the main body of the sewage pumping station, and a ladder is fixed on the top surface of the maintenance platform. The top surface of the ladder is fixedly connected to the top surface of the main body of the sewage pumping station. The ladder is close to the inlet and outlet of the pumping station. A check valve is provided at the end of each sewage pipe near the shut-off valve. The check valve is located below the shut-off valve.

[0008] Furthermore, the sewage pump body includes a first sewage pump, a second sewage pump, and a third sewage pump, and the sewage pump body is fixed to the bottom of the sewage pumping station body by a fixing ring.

[0009] Furthermore, the water level detector body includes a first water level detector, a second water level detector, and a third water level detector. The distance between any two adjacent water level detector bodies is equal, and each water level detector body is located below the sewage inlet pipe.

[0010] Furthermore, an internal vent pipe is fixed on the top surface of the pump station inlet and outlet, and the internal vent pipe is connected to the interior of the sewage pump station body, with the bottom end of the internal vent pipe located below the maintenance platform.

[0011] Furthermore, a protective railing is fixed on the ladder, and an external vent pipe is fixed on the top surface of the pump station inlet and outlet. The external vent pipe is connected to the interior of the sewage pump station body and is located above the maintenance platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by fixing the main body of the sewage pumping station inside the pump well pit, and controlling the corresponding sewage pumps through several water level detectors, the sewage pumping station automatically discharges sewage when the sewage reaches different water level detectors. This allows the sewage pumping station to control the number of sewage pumps to be started according to the amount of sewage, thereby improving the sewage discharge efficiency. This solves the problem that the existing sewage treatment method involves transmitting sewage into the pump well and then having workers start the sewage pumps to output the sewage from the pump well. However, the time when sewage flows into the pump well is not fixed, which requires workers to start the sewage pumps in a timely manner to pump out the sewage, otherwise sewage will accumulate inside the pump well or even cause sewage backflow.

[0014] 2. In this utility model, a maintenance platform is set inside the main body of the sewage pumping station, allowing workers to climb the ladder to enter the main body of the sewage pumping station to inspect the sewage pipe and the sewage outlet pipe. At the same time, the shut-off valve and check valve installed on the sewage pipe facilitate the maintenance of the equipment by the workers, and also prevent the sewage from flowing back into the main body of the sewage pumping station after maintenance. In addition, a safety railing is set on one side of the ladder to prevent workers from falling when entering the main body of the sewage pumping station. Attached Figure Description

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An integrated closed-loop sewage lifting pump station includes a sewage pump station body 1, with a pump station inlet and outlet 2 on the top surface of the sewage pump station body 1, a sewage inlet pipe 3 on one side of the sewage pump station body 1, and several sewage pump bodies 4 inside the sewage pump station body 1. Each sewage pump body 4 is connected to a sewage pipe 6 through a flange, and the top surface of each sewage pipe 6 is connected to a sewage outlet pipe 7. A shut-off valve 9 is installed at the end of each sewage pipe 6 near the sewage outlet pipe 7. A water level detector body 8 corresponding to the number of sewage pump bodies 4 is installed inside the sewage pump station body 1 near the sewage inlet pipe 3. Each water level detector body 8 is electrically connected to a different sewage pump body 4. Sewage is automatically discharged through the water level detector body 8 and the sewage pump body 4.

[0023] Specifically, the sewage pump body 4 includes a first sewage pump 441, a second sewage pump 442, and a third sewage pump 443. The sewage pump body 4 is fixed to the bottom of the sewage pump station body 1 by a fixing ring 5. The water level detector body 8 includes a first water level detector 881, a second water level detector 882, and a third water level detector 883. The distance between any two adjacent water level detector bodies 8 is equal. Each water level detector body 8 is located below the sewage inlet pipe 3, so that the corresponding water level detector body 8 controls the corresponding sewage pump body 4.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a maintenance platform 11 is fixed in the middle of the main body 1 of the sewage pumping station. A ladder 12 is fixed on the top surface of the maintenance platform 11. The top surface of the ladder 12 is fixedly connected to the top surface of the main body 1 of the sewage pumping station. The ladder 12 is close to the inlet and outlet 2 of the pumping station. A check valve 10 is installed at the end of each sewage pipe 6 near the stop valve 9. The check valve 10 is located below the stop valve 9 to facilitate maintenance by staff.

[0025] Specifically, an internal vent pipe 14 is fixed on the top surface of the pump station inlet and outlet 2. The internal vent pipe 14 is connected to the interior of the main body 1 of the sewage pump station. The bottom end of the internal vent pipe 14 is located below the maintenance platform 11. A protective railing 13 is fixed on the ladder 12. An external vent pipe 15 is fixed on the top surface of the pump station inlet and outlet 2. The external vent pipe 15 is connected to the interior of the main body 1 of the sewage pump station. The external vent pipe 15 is located above the maintenance platform 11 to prevent workers from being injured during maintenance.

[0026] Working Principle: By fixing the main body 1 of the sewage pumping station within the pump well pit, the sewage entering the main body 1 does not directly contact the ground, preventing sewage overflow and pollution of the surrounding environment. Simultaneously, when sewage enters the main body 1, if the sewage level reaches the first water level detector 881, the first water level detector 881 activates the first sewage pump 441 to discharge the sewage. If the sewage level reaches the second water level detector 882, the second water level detector 882 activates the second sewage pump 442, allowing both sewage pumps to operate simultaneously, increasing the sewage discharge capacity. Each sewage pump discharges a significant amount of sewage. The sewage is transmitted through the corresponding sewage pipe 6 to the sewage outlet pipe 7, and then discharged through the sewage outlet pipe 7. At the same time, the shut-off valve 9 on each sewage pipe 6 prevents the sewage inside the sewage outlet pipe 7 from flowing back into the sewage pump station body 1. When the staff needs to repair the sewage outlet pipe 7, they can enter the sewage pump station body 1 through the pump station inlet / outlet 2 and the ladder 12. At the same time, the guardrail 13 prevents the staff from falling. At this time, the staff can repair the sewage outlet pipe 7 and the sewage pipe 6 on the maintenance platform 11. At the same time, the check valve 10 prevents the sewage from gushing out during the staff's maintenance.
