Description

Technical Field

[0001] The utility model relates to the technical field of integrated pump stations, in particular to an integrated pump station capable of self-cleaning a pit bottom. Background Art

[0002] The integrated prefabricated pump station is a lifting equipment for sewage, rainwater, drinking water and wastewater. It is a pressure pump station that is uniformly produced and assembled by the factory and then transported to the site for installation. Simply put, it is a new type of sewage treatment equipment designed specifically for urban rainwater collection and drainage, as well as urban sewage lifting.

[0003] Patent CN112443038A discloses an integrated pump station for dredging as an example. A dredging net plate is fixedly installed at the bottom of the cylinder of the pump station. The accumulated silt will automatically fall into the silt discharge cavity in the base with the mesh holes in the dredging net plate due to its own gravity. A water pump can be fixedly installed on the outer surface of the water inlet pipe. Through the suction provided by the water pump, a water flow with a certain impact force begins to flush the silt in the silt discharge cavity. The silt is discharged from the silt discharge pipe along with the water flow. The staff can also open the top cover and enter the bottom of the cylinder of the pump station along the ladder to manually clean the silt. This patent flushes and cleans the pit bottom by the silt's own gravity and the water flow of the water pump. However, in actual use, the accumulated silt will adhere to the side wall of the bottom of the pump station and may block the dredging net plate, causing the silt to fail to fall quickly. This requires the staff to dredge regularly to ensure the smoothness of the side wall and the dredging net plate. Therefore, there are problems such as low degree of automatic cleaning of the pit bottom, low cleaning efficiency, and high work intensity of the staff. Utility Model Content

DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1 As shown, an integrated pump station capable of self-cleaning the bottom of a pit comprises a pump station shell 1, a water inlet pipe 2 and a water outlet pipe 3 are arranged on the side wall of the pump station shell 1, the water inlet pipe 2 is arranged at the bottom of the side wall of the pump station shell 1, the water outlet pipe 3 is arranged at the upper part of the side wall of the pump station shell 1, an upper cover 4 is arranged on the upper surface of the pump station shell 1, a ladder 5 is arranged below the upper cover 4 and on the inner wall of the pump station shell 1, a crushing grid 6 connected to the water inlet pipe 2 is arranged in the pump station, the crushing grid 6 is a common device and will not be described in detail, and A maintenance platform 7 is provided with an inspection port on the maintenance platform 7, a water pump mechanism is provided in the pump station, a self-cleaning mechanism for discharging sludge and garbage at the bottom of the pit connected to the maintenance platform 7, and a control mechanism, the water pump mechanism includes a plurality of submersible pumps 8, connecting pipes 9 connected to the submersible pumps 8, the connecting pipes 9 are connected to the outlet pipe 3, a manual control valve 10 is provided at the connection between the connecting pipe 2 and the outlet pipe 3, the manual control valve 10 is closed during maintenance, and the submersible pump 8 can be fixed on the inner wall of the pump station shell 1.

[0022] The self-cleaning mechanism comprises a motor 11 disposed on the upper surface of the maintenance platform 7 , the output end of the motor 11 is connected to a connecting rod 12 , and the connecting rod 12 is connected to a cleaning component.

[0023] like Figure 2 As shown, the cleaning assembly includes a connecting disk 13 connected to a connecting rod 12, the connecting disk 13 is detachably connected with a stirring portion, and the connecting rod 12 and the connecting disk 13 can be connected by threads.

[0024] The stirring part includes a stirring rod 14, at the bottom of which is a stirring claw 15 extending in the same direction as the stirring rod 14. When rotating, the side of the stirring claw 15 has a greater contact with the wastewater, forming a larger vortex, driving the sludge and garbage to flow, which is sucked away and discharged by the submersible pump 8 to prevent the sludge and garbage from settling and accumulating.

[0025] The control mechanism includes a liquid level sensor arranged in the pump station housing, and also includes a controller 16 arranged outside the pump station housing 1. The controller 16 receives signals from the liquid level sensor and controls the operation of the submersible pump 8, the motor 11, and the crushing grid 6.

[0026] Usage process: wastewater enters the pump station through the water inlet pipe 2 and the crushing grid 6. The larger garbage in the wastewater is crushed into smaller garbage by the crushing grid 6. The liquid level sensor senses the liquid level and sends a signal to the controller 16 after reaching the specified height. The controller 16 controls the submersible pump 8 to pump water. At the same time, the controller 16 controls the motor 11 to rotate, driving the stirring rod 14 and the stirring claw 15 to rotate, forming a vortex, so that the sludge garbage flows quickly. The sludge garbage is sucked away and discharged by the submersible pump 8. Setting up several submersible pumps 8 can increase the suction force and prevent the submersible pump 8 from being damaged and stopped, ensuring that the submersible pump 8 is always running, thereby improving production efficiency; when the water level drops to the set value, the controller 16 controls the motor 11, the submersible pump 8, and the crushing grid 6 to stop; the motor 11 can be connected to the frequency regulator. When sludge garbage accumulates at the bottom of the pit, the controller 16 can control the motor 11 to increase the speed, driving the accumulated sludge garbage to be discharged from the bottom of the pit.

[0027] Embodiment 2

[0028] The difference from the first embodiment is that the stirring portion is a plurality of fan-shaped stirring members arranged obliquely, such as Figure 3 As shown, a large vortex is formed during rotation, driving the sludge and garbage to flow, which is then sucked away and discharged by a submersible pump, thus preventing the sludge and garbage from settling and accumulating.

[0029] The above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
