Description

Technical Field

[0001] This utility model relates to the field of sewage treatment using sewage pumps, specifically a prefabricated sewage pump station. Background Technology

[0002] Prefabricated sewage pumping stations are modular, prefabricated sewage treatment equipment used in urban, industrial, or small-scale sewage treatment systems to lift sewage from low-level to higher levels so that it can enter the pipe network or treatment plant. Compared with traditional integrated pumping stations, prefabricated pumping stations adopt a modular structure design, which facilitates rapid on-site installation and disassembly. At the same time, the capacity and equipment configuration of the pumping station can be flexibly adjusted according to different project needs. During operation, the pumping station not only needs to ensure the efficient lifting and transportation of sewage, but also needs to prevent siltation at the bottom of the pump body, pipe blockage, and equipment failure, ensuring the stability of the drainage system and the city's flood control capabilities. The prefabricated sewage pumping station mainly consists of a pumping station shell, inlet, outlet, maintenance platform, electrical control cabinet, submersible pump, pressure pipeline, ladder, fixed angle iron, and ventilation pipe. Sewage flows into the pumping station shell through the inlet. The submersible pump is installed at the bottom of the pump body and is firmly supported by the fixed angle iron, pumping the sewage to the outlet and then transporting it to the drainage network or sewage treatment facilities through the pressure pipeline. The maintenance platform and ladder provide a safe passage for operators and maintenance personnel, facilitating the inspection and maintenance of the submersible pump and pipeline. The electrical control cabinet is responsible for the start-up and shutdown of the pump and power management, while the ventilation pipe is used to remove moisture and odors from inside the pumping station, ensuring internal air circulation and long-term stable operation of the equipment.

[0003] In the prior art, such as a prefabricated sewage lifting pump station with application number CN202421384601.2, a deodorizing box is installed inside the cylinder, and a deodorizing agent box is installed at the bottom of the deodorizing box. The deodorizing agent box can spray deodorizing agent into the inside of the deodorizing box through a liquid pump and a conduit, which can effectively deodorize the gas entering the deodorizing box. At the same time, an activated carbon plate is installed inside the deodorizing box, which can further deodorize the gas and effectively reduce the odor when the gas is discharged.

[0004] However, during use, it relies on a filter screen or sedimentation structure to perform preliminary treatment of the inlet sewage, but under the impact of water flow, sludge deposition and impurity accumulation are prone to occur, leading to blockage at the bottom of the pump body and reduced drainage efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated sewage pumping station to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a pump station housing, an inlet is provided on the surface of the pump station housing, and a treatment box is installed at the other end of the inlet via a flange. The treatment box is equipped with a filter structure, which is used to filter the sewage entering from the inlet. The bottom of the treatment box is connected to a sewage discharge channel, and the other end of the sewage discharge channel is connected to a collection box.

[0007] Preferably, the treatment box is located inside the pump station shell, and the interior of the treatment box has an installation groove with a ring structure.

[0008] Preferably, the filter structure includes a bearing, a filter metal disc, a connecting frame, and a guide vane. The bearing is embedded in the mounting groove, the filter metal disc is installed on the inner ring of the bearing, the connecting frame is fixed inside the treatment box, the guide vane is sleeved on the outer ring of the connecting frame, and the guide vane is located directly in front of the filter metal disc. Multiple sets of guide vanes are provided, and the multiple sets of guide vanes are arranged in a circumferential array around the central axis of the connecting frame. The filter metal disc is installed in the drain outlet of the treatment box.

[0009] Preferably, the surface of the filter metal disc is provided with through holes, and there are multiple sets of through holes, all of which penetrate the filter metal disc. The multiple sets of through holes are arranged in a circular array around the center of the filter metal disc, and all of the multiple sets of through holes are inclined and at a 60° angle to the surface of the filter metal disc.

[0010] Preferably, the guide vane is inclined, and the inclination angle of the guide vane is the same as the inclination angle of the filter metal disc.

[0011] Preferably, the bottom of the collection box is provided with a filter screen, the sewage discharge channel is connected to the inner wall of the treatment box, and the sewage discharge channel is located directly in front of the filter metal disc.

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

[0013] The prefabricated sewage pumping station proposed in this utility model pumps sewage to the inlet, and then through the treatment tank. Inside the treatment tank, the sewage first passes through the inlet. When the water flows through the tank, it drives the inclined guide vanes to rotate, which disperses the accumulated sludge. When large particles of impurities impact the filter metal disc, they are intercepted by the through holes. Finally, due to gravity, they fall into the sewage discharge channel at the bottom. Because of the inclined through holes, the filter metal disc rotates when impacted, which further disperses the sewage, making it difficult for impurities to accumulate and allowing the sewage to be discharged continuously and smoothly.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1-6 This utility model provides a technical solution: a prefabricated sewage pumping station, including a pumping station shell 1, an inlet 2 is provided on the surface of the pumping station shell 1, and a treatment box 3 is installed at the other end of the inlet 2 through a flange. The treatment box 3 is located inside the pumping station shell 1, and an installation groove 5 is provided inside the treatment box 3. The installation groove 5 has a ring structure.

[0024] Specifically, the prefabricated sewage pumping station consists of a pumping station shell 1, an inlet 2, an outlet, a maintenance platform, an electrical control cabinet, a submersible pump, pressure pipelines, a ladder, fixed angle irons, and ventilation pipes. The fixed angle irons are used to fix the pumping station shell 1 and prevent it from shaking naturally. In the prefabricated sewage pumping station, sewage flows into the pump pit through the inlet 2. The submersible pump is installed at the bottom of the pump pit. When the water level reaches a certain height, the submersible pump starts and pumps the sewage upwards, which is then transported to the outlet through the pressure pipeline. The outlet is connected to an external pipeline to send the sewage into the sewage treatment system or discharge line. During daily operation, the maintenance platform provides a safe passage and operating space for maintenance personnel to enter the pumping station. The ladder is used to go up and down the pump pit for inspection and maintenance. Ventilation pipes are installed at the top or manhole cover to remove odors and moisture caused by sewage, submersible pump operation, or temperature differences inside the pumping station, in order to maintain internal air circulation and reduce corrosion and odor accumulation. The prefabricated sewage pumping station adopts the same model as the integrated pumping station from Shandong Huake.

[0025] To reiterate, the electrical control cabinet, as the electrical control center of the pumping station, rationally distributes external power to the submersible pumps and auxiliary equipment through internal wiring and power distribution, ensuring safe power supply for the equipment. Its start-stop function is achieved through control switches, contactors, or circuit breakers. When it receives a manual operation or preset signal, the control cabinet can close the circuit to start the submersible pump; conversely, it can open the circuit to stop the submersible pump. Simultaneously, the control cabinet is equipped with overload protection, short-circuit protection, and current monitoring devices, which can manage current and voltage in real time during pump operation, preventing damage to the submersible pump due to voltage fluctuations or abnormal currents, thereby ensuring the overall safety and stability of the pumping station's operation.

[0026] Example 2

[0027] Based on Embodiment 1, in order to treat wastewater and prevent blockage at the bottom of the pump body, a filter structure is embedded inside the treatment tank 3. This filter structure filters the wastewater entering through the inlet 2. The filter structure includes a bearing 6, a filter metal disc 7, a connecting frame 8, and guide vanes 9. The bearing 6 is embedded in the mounting groove 5, the filter metal disc 7 is installed on the inner ring of the bearing 6, the connecting frame 8 is fixed inside the treatment tank 3, and the guide vanes 9 are fitted onto the outer ring of the connecting frame 8, with the guide vanes 9 positioned directly in front of the filter metal disc 7. Multiple sets of guide vanes 9 are arranged in a circular array around the central axis of the connecting frame 8. The filter metal disc 7 is installed at the drain outlet of the treatment tank 3. Inside the filter metal disc 7, there are multiple sets of through holes 10 on the surface of the filter metal disc 7. All sets of through holes 10 penetrate the filter metal disc 7 and are arranged in a circular array around the center of the filter metal disc 7. All sets of through holes 10 are inclined and at a 60° angle to the surface of the filter metal disc 7. The guide plate 9 is also inclined and the inclination angle of the guide plate 9 is the same as that of the filter metal disc 7. The bottom of the treatment box 3 is connected to a sewage discharge channel 11, and the other end of the sewage discharge channel 11 is connected to a collection box 12. A filter screen 13 is provided at the bottom of the collection box 12. The sewage discharge channel 11 is connected to the inner wall of the treatment box 3 and is located in front of the filter metal disc 7.

[0028] Specifically, when sewage is pumped to inlet 2 and enters treatment tank 3, the water flow first impacts the inclined guide vane 9 located at the front. The guide vane 9 rotates under the impact, continuously dispersing the sludge originally accumulated in treatment tank 3, thus preventing sedimentation and blockage at the inlet. Subsequently, larger impurities entering with the water flow directly impact the filter metal disc 7 located at outlet 4. Since the surface of the filter metal disc 7 has multiple sets of inclined through holes 10, the impurities are effectively intercepted by the through holes 10 during the impact, unable to continue flowing with the sewage, and naturally fall into the sewage discharge channel 11 below under the action of gravity, eventually flowing into collection tank 12. The filter screen 13 at the bottom of collection tank 12 further blocks small impurities, ensuring the cleanliness of the discharged water, and the sewage continues to flow to the bottom of the pump body. At the same time, during the process of the water flow impacting the inclined through holes 10, it will drive the filter metal disc 7 to rotate, causing the sewage to be dispersed again on the surface of the filter metal disc 7, thereby reducing the accumulation of impurities near the through holes 10 and avoiding the risk of blockage.

[0029] In operation, when wastewater flows into the inlet 2 through the pump station housing 1, it first enters the treatment tank 3. During this process, the water flow directly impacts the inclined guide vanes 9 located on the outer ring of the connecting frame 8. The guide vanes 9 rotate under the action of the water flow, continuously dispersing the sludge that was originally accumulated in the treatment tank 3, preventing sedimentation and blockage at the inlet. Subsequently, larger impurities that enter with the water flow continue to advance and impact the filter metal disc 7 located at the drain outlet 4. The filter metal disc 7 is embedded in the mounting groove 5 through bearings 6 and can rotate flexibly under the action of the water flow. Its surface is distributed with multiple sets of inclined through holes 10. When impurities collide, they are effectively intercepted by the through holes 10 and cannot be discharged with the wastewater. Under the action of gravity, they naturally fall into the sewage discharge channel 11 directly below. The sewage discharge channel 11 is connected to the collection tank 12. The impurities finally enter the collection tank 12 and are further screened by the filter screen 13 at its bottom to block fine impurities, ensuring that the subsequently discharged water is cleaner. Meanwhile, when the water flow impacts the through hole 10, it causes the filter metal disc 7 to rotate, which disperses the water on the surface of the metal disc 7 again, thereby reducing the accumulation of impurities near the through hole 10.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
