Description

Technical Field

[0001] The invention relates to the technical field of pump stations, and in particular to an integrated prefabricated pump station. Background Art

[0002] The integrated prefabricated pump station is a lifting equipment for sewage, rainwater and wastewater. The existing integrated prefabricated pump station's built-in gratings are mainly divided into basket gratings and crushing gratings. The crushing gratings can crush solid waste and prevent large fixed waste from clogging the submersible sewage pump. It requires less manual intervention and is more convenient.

[0003] During the long-term operation of the integrated prefabricated pump station, most of the solid waste crushed by the crushing grid can be discharged from the integrated prefabricated pump station by the submersible sewage pump, and a small part will accumulate inside the integrated pump station, which requires manual cleaning later, which is troublesome and reduces the continuity of the drainage work of the integrated prefabricated pump station. The solid waste accumulated inside the integrated prefabricated pump station is mainly divided into two types: floating solid waste and deposited solid waste. The deposited solid waste is divided into two types: sludge and solid fragments (such as gravel).

[0004] The existing pumping stations can mix the silt again into the sewage by stirring and discharge it through the submersible sewage pump. The mixing of the deposited silt and sewage is likely to increase the workload of the later sewage treatment and reduce the sewage treatment efficiency. When the water level is high and relatively stable, the floating solid waste is difficult to be stirred and mixed into the bottom of the sewage and discharged through the submersible sewage pump, which can easily cause the floating solid waste to accumulate above the sewage and produce toxic gases. Even after the water level drops suddenly, a large amount of floating solid waste is likely to clog the submersible sewage pump. Therefore, manual salvage is required regularly, affecting the continuity of the drainage work of the pumping station. Because of its high density, the solid fragments are deposited at the bottom of the pumping station and are difficult to be discharged through the submersible sewage pump. Workers are required to regularly enter the pumping station to clean up the solid fragments, which is more troublesome. Summary of the invention

[0005] In view of the above-mentioned defects, the purpose of the present invention is to provide an integrated prefabricated pump station, which can lift sewage and further facilitate the discharge of solid waste in the pump station, without the need for workers to enter the sewage storage barrel to clean the solid waste, thereby improving the continuity of the operation of the integrated prefabricated pump station; the conical bottom of the sewage storage barrel can facilitate the deposited solid waste to slide down under the action of gravity and enter the regulating box for storage; the solid-discharging submersible sewage pump, hose, and lifting device can cooperate to facilitate the discharge of solid waste floating on the top of the sewage in the sewage storage barrel; the setting of the arc-shaped guide plate can promote the circumferential movement of the sewage in the sewage storage barrel, and the suspended solid waste moves toward the edge of the sewage storage barrel to facilitate the final entry into the hose; the setting of the strip grille can intercept the solid waste in the storage barrel, preventing a certain volume of solid waste from entering the storage barrel again through the sewage pipe.

Detailed Embodiment

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] See Figure 1 、 Figure 2 、 Figure 3 , the present invention provides an integrated prefabricated pumping station, which includes a sewage storage tank 1. The sewage storage tank 1 serves as a transfer station for sewage to temporarily store sewage. The bottom of the sewage storage tank 1 is conical, and the conical bottom of the sewage storage tank 1 can facilitate the movement of the deposited solid waste towards the lower part in the middle under the action of gravity. A drainage submersible pump and a solid discharge submersible pump are fixedly connected to the inner bottom of the sewage storage tank 1. The drainage submersible pump is connected to the drainage pipe 3. The drainage submersible pump can drive the sewage in the sewage storage tank 1 to move. The drainage submersible pump drives the sewage in the sewage storage tank 1 to move into the drainage pipe 3, and the sewage entering the drainage pipe 3 is finally discharged from the sewage storage tank 1.

[0025] The solid discharge submersible pump is connected to one end of the solid discharge pipe 5. The solid discharge submersible pump can drive the sewage to move, and the movement of the sewage drives the suspended solid waste to move through the solid discharge pipe 5 and be discharged from the sewage storage tank 1. The other end of the solid discharge pipe 5 is connected to the adjustment tank 7. The conical bottom end of the sewage storage tank 1 is connected to the top end of the sewage discharge pipe 8. Electric control valves 6 are arranged on both the sewage discharge pipe 8 and the solid discharge pipe 5. The bottom end of the sewage discharge pipe 8 communicates with the adjustment tank 7. The adjustment tank 7 is located below the sewage storage tank 1, and the adjustment tank 7 is provided with an openable and closable solid discharge port. When the electric control valve 6 on the sewage discharge pipe 8 is opened and the electric control valve 6 on the solid discharge pipe 5 is closed, the deposited solid waste (including sediments such as silt and gravel) in the sewage storage tank 1 can fall into the adjustment tank 7 under the action of gravity for storage. After a certain amount of solid waste is deposited in the adjustment tank 7, the worker can open the solid discharge port to clean the deposited solid waste in the adjustment tank 7 after closing the electric control valve 6 on the sewage discharge pipe 8.

[0026] Inside the sewage storage bucket 1, a crushing grille is fixedly connected. The crushing grille can crush solid waste to prevent large-sized solid waste from blocking the drainage submersible pump or the solid discharge submersible pump. The crushing grille is connected to the water inlet pipe 2. The solid waste in the water inlet pipe 2 enters the sewage storage bucket 1 after being crushed by the crushing grille. The water inlet of the solid discharge submersible pump is connected to the bottom end of a hose (for example: a rubber hose with steel wire). The setting of the hose can facilitate deformation, making it convenient to adjust the height of the top end of the hose, and thus facilitating the introduction of the sewage at the top end position of the hose into the water inlet position of the solid discharge submersible pump, which is applicable to the situation where the water level in the sewage storage bucket 1 is different. Inside the sewage storage bucket 1, a lifting device is provided (the lifting device is used to adjust the height position of the top end of the hose, such as a hydraulic lifting device or a screw rod lifting device, which is prior art and will not be elaborated here). The lifting device is used to drive the top end of the hose to rise or fall. A liquid level gauge is provided inside the sewage storage bucket 1. The liquid level gauge is electrically connected to the lifting device. The liquid level gauge is used to detect the height of the liquid level. During the operation of the solid discharge submersible pump, the working state of the lifting device is regulated according to the height of the liquid level to keep the top end of the hose always at a certain distance below the sewage liquid level in the sewage storage bucket 1. The cooperation of the solid discharge submersible pump, the lifting device, and the hose can facilitate the discharge of the solid waste floating above the sewage from the sewage storage bucket 1 without the need for workers to separately open the sewage storage bucket 1 to fish and clean the floating solid waste.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , further, a plurality of arc-shaped guide plates 12 are fixedly connected to the conical bottom end position of the sewage storage bucket 1 of the present invention. The arc-shaped guide plates 12 are evenly distributed along the circumferential direction. A water baffle 13 is fixedly connected above the arc-shaped guide plates 12. The settings of the arc-shaped guide plates 12 and the water baffle 13 can change the flow direction of the sewage entering the sewage storage bucket 1 from the drain pipe 3, so that the sewage can wash the inner wall of the bottom of the sewage storage bucket 1, and the water flow flowing out after passing through the arc-shaped guide plates 12 can drive the stored sewage in the sewage storage bucket 1 to rotate. A filter grille is sleeved outside the drainage submersible pump. The filter grille is fixedly connected to the sewage storage bucket 1. The setting of the filter grille can filter the sewage entering the drainage submersible pump, and can greatly reduce the solid waste discharged from the sewage storage bucket 1 via the drainage submersible pump, reducing the content of solid waste in the sewage discharged by the drainage submersible pump. When a large amount of solid waste enters the sewage discharge pipe 8 or the gap between the arc-shaped guide plates 12 under the action of gravity at the same time, it is easy to cause blockage after multiple solid wastes come into contact with each other. When the sewage is driven by the solid discharge submersible pump and passes through the sewage discharge pipe 8 or the gap between the arc-shaped guide plates 12, it can wash away the blockage and play a role in backwashing.

[0028] Inside the adjustment box 7, a strip-shaped grille 10 is slidably connected. Workers can push the strip-shaped grille 10 to change its position. The strip-shaped grille 10 is used to filter the sewage flowing from the solid discharge pipe 5 to the sewage discharge pipe 8. The setting of the strip-shaped grille 10 can intercept solid waste with a certain volume and prevent solid waste with a certain volume that enters the adjustment box 7 from entering the storage sewage bucket 1 again through the sewage discharge pipe 8. The solid discharge pipe 5 is connected to the bottom of the left side wall of the adjustment box 7. A bending part is arranged below the strip-shaped grille 10, and the bending part bends towards the left side of the strip-shaped grille 10. The right side of the top surface of the adjustment box 7 is connected to the sewage discharge pipe 8. The setting of the bending part can prevent the sewage flow direction 11 from being perpendicular to the strip-shaped grille 10, avoiding solid waste from adhering to the strip-shaped grille 10 under the impact of sewage and blocking the strip-shaped grille 10 (the solid waste entering the adjustment box 7 through the solid discharge pipe 5 itself has a certain buoyancy. When the water flow impacts the bending part, part of the water flow moves upward, which can also drive the solid waste to move upward. The cooperation of the two can prevent the bending part position of the strip-shaped grille from being blocked by solid waste).

[0029] See Figure 1 , Figure 2 , Figure 3 , Further, the top end of the hose of the present invention is located at the edge position inside the storage sewage bucket 1. The sewage inside the storage sewage bucket 1 makes a rotational motion driven by the sewage flowing into the storage sewage bucket 1 through the gaps between the arc-shaped guide plates 12. The solid waste floating on the surface of the sewage moves along with the sewage. At the same time, the solid waste moves towards the edge of the storage sewage bucket 1 under the action of centrifugal force, so that all the solid waste suspended in the storage sewage bucket 1 can move above the top end of the hose and finally be discharged from the storage sewage bucket 1. When the solid waste discharging and sewage pumping pump works, the top end of the hose is always within a range of five centimeters below the liquid level inside the storage sewage bucket 1. An avoidance space for solids to pass through is arranged between two adjacent arc-shaped guide plates 12. The setting of the avoidance space can facilitate the passage of solid waste such as broken stones.

[0030] An inspection opening 4 is arranged at the top of the storage sewage bucket 1. Opening the inspection opening 4 can facilitate workers to enter the inside of the storage sewage bucket 1 to inspect and repair the components inside the storage sewage bucket 1. A camera is fixedly connected at the upper position inside the storage sewage bucket 1. The camera can photograph the inside situation of the storage sewage bucket 1 to facilitate assisting workers in judging whether the suspended solid waste has been completely discharged. The solid discharge port of the adjustment box 7 is located at the top of the adjustment box 7. The solid discharge port is provided with a detachable sealing cover 9. After opening the sealing cover 9, workers can clean the solid waste inside the adjustment box 7. A transparent observation window plate is arranged on one side of the adjustment box 7. The observation window plate can facilitate workers to observe the content of solid waste inside the adjustment box 7, and further facilitate workers to judge whether it is necessary to clean the solid waste inside the adjustment box 7.

[0031] Working principle: The drainage and sewage pump and the crushing grille can work continuously or intermittently according to the actual situation; when discharging sludge, the electric valve on the sewage discharge pipe 8 is opened, the electric valve on the solid discharge pipe 5 is closed, the strip grille 10 is moved away from the sewage discharge pipe 8, and the solid waste deposited in the storage tank 1 falls into the adjustment tank 7 for storage. When the solid waste in the adjustment tank 7 reaches a certain content, the electric valve on the sewage discharge pipe 8 is closed, the sealing cover 9 is opened, and the worker cleans the solid waste in the adjustment tank 7. This process can be repeated multiple times until the deposited solid waste is completely cleaned; after the solid waste is cleaned, the worker pushes the strip grille 10 away from the solid discharge pipe 5, closes the sealing cover 9, opens the electric valve on the sewage discharge pipe 8, opens the electric valve on the solid discharge pipe 5, the solid discharge submersible pump works, the liquid level gauge monitors the liquid level, and the lifting device adjusts the height of the top end of the hose to be within five centimeters below the liquid surface. The suspended solid waste with a certain volume finally enters the adjustment tank 7 for storage. When the solid waste in the adjustment tank 7 reaches a certain content, the solid discharge submersible pump is turned off, all electric valves are closed, the sealing cover 9 is opened, and the worker cleans the solid waste in the adjustment tank 7. This process can be repeated multiple times until the floating solid waste is completely cleaned.

[0032] In summary, the present invention provides an integrated prefabricated pumping station, including a storage tank. The bottom of the storage tank is conical. The conical bottom of the storage tank can facilitate the deposition of solid waste to gather towards the middle under the action of gravity. The inner bottom of the storage tank is fixedly connected with a drainage submersible pump and a solid discharge submersible pump. The drainage submersible pump is connected to the drainage pipe. The arrangement of the drainage submersible pump and the drainage pipe can facilitate the lifting of sewage and discharge the sewage from the storage tank; one end of the solid discharge submersible pump is connected to the solid discharge pipe, and the other end of the solid discharge pipe is connected to the adjustment tank.

The adjustment tank can facilitate the storage of sludge or crushed stones that fall into the adjustment tank under the action of gravity. The adjustment tank is provided with an openable and closable solid discharge port. The arrangement of the solid discharge port can facilitate the discharge of solid waste from the adjustment tank. The cooperation of the solid discharge submersible pump and the solid discharge pipe can discharge floating solid waste, preventing solid waste from accumulating inside the storage tank; a crushing grille is fixedly connected inside the storage tank, and the crushing grille is connected to the water inlet pipe. The arrangement of the crushing grille can crush solid waste, preventing large solid waste from blocking the drainage submersible pump or the solid discharge submersible pump; the water inlet of the solid discharge submersible pump is connected to the bottom end of the hose.
