Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a double U-shaped pump body built-in removable filtering device. Background Art

[0002] Sewage pumping station is an important part of sewage system. The lifting pump is installed in the sewage pipe system to pump up urban sewage. Its function is to raise the elevation of sewage. Since the sewage collected by the urban sewage interception network is large in area and far away from the sewage treatment plant, it is impossible to bury the pipes very deep, and most of the sewage pipes are gravity flow mode, so it is necessary to set up a pumping station to raise the elevation of sewage, so as to introduce municipal sewage from lower terrain into various sewage treatment stations with higher terrain.

[0003] However, in the process of transporting sewage, although the lift pump itself has a simple filtering device built in, the lift pump malfunctioned after a period of use. After testing the pump station control cabinet and arranging personnel to go down the well to inspect the inlet and outlet of the pumping machine, it was found that the filtering device was blocked. Professional personnel must be arranged regularly for operation and maintenance, and it is difficult to dismantle the filtering device that comes with the pump body. Utility Model Content

[0004] In order to facilitate the removal of the filter device in the pump body for maintenance, the present application provides a double U-shaped pump body with a built-in removable filter device.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A double U-shaped pump body with a built-in removable filtering device includes a water pipe, wherein two ends of the water pipe are respectively provided with a water inlet and a water outlet, a first bend pipe and a second bend pipe are provided between the water inlet and the water outlet, and fixings are provided on the outer wall of the water pipe close to the water inlet and the water outlet. The water pipe is detachably connected between the sewage pipe network and the lifting pump through the fixings.

[0007] By adopting the above device, by setting the first elbow and the second elbow, the curvature of the water pipe is increased, which helps to improve the dynamic characteristics of the water flow, reduce the accumulation of sediments, and thus improve the filtering efficiency. In addition, the design of the fixings allows for quick disassembly and installation between the water pipe and the sewage pipe and the lifting pump, which is convenient for maintenance and cleaning, reduces maintenance costs and time, and also improves the flexibility and adaptability of the device, so that it can adapt to different environments and needs. The built-in design reduces the need for external filtering equipment, saves space, and reduces the complexity of the system.

[0008] Preferably, the water inlet is used to connect to an upstream sewage pipe, and the water outlet is used to connect to a lift pump.

[0009] Preferably, the height of the water outlet is greater than that of the water inlet.

[0010] By adopting the above device, the water inlet is connected to the sewage pipe at a lower place, and the water outlet is connected to the lift pump at a higher place to introduce it into the lift pump. At the same time, the design that the water outlet is higher than the water inlet enables the lift pump to suck sewage more effectively during operation, reducing the suction loss of the pump. When the lift pump sucks sewage, since the water outlet is at a higher position, the pressure at the pump inlet can be reduced, thereby reducing the occurrence of cavitation.

[0011] Preferably, a seal is provided inside the fixing member. When connecting, the fixing member presses against the seal, making the seal tightly adhere to the pipe wall of the water pipe.

[0012] By adopting the above device, the seal provided inside the fixing member is pressed tightly during connection, ensuring that the seal can closely fit the pipe wall of the water pipe, thereby enhancing the sealing performance of the connection part and effectively preventing sewage leakage.

[0013] Preferably, valves are provided at the water inlet and the water outlet for controlling the on-off of the water flow.

[0014] By adopting the above device, the valves can be opened or closed to control the on-off of the water flow, thereby regulating the sewage flow. At the same time, by adjusting the opening degree of the valves, the water flow velocity can be changed, thereby affecting the pressure in the pipeline. When it is necessary to remove the water pipe, the water flow can be cut off by closing the valves to ensure safety.

[0015] Preferably, fasteners are provided outside the valves, and the fasteners are detachably connected to the valves.

[0016] By adopting the above device, since the fasteners and the valves are detachably connected, the installation, disassembly, and maintenance processes of the valves are made more simple and rapid. When the valves need to be replaced, the fasteners can be removed.

[0017] Preferably, a supporting part is provided at the bottom of the water pipe. The supporting part includes a first step and a second step. The first step is provided at the bottom of the water inlet, and the second step is provided at the bottom of the water outlet, and the height of the second step is greater than that of the first step.

[0018] By adopting the above device, the supporting part plays a supporting role, effectively supporting the water pipe, making the pressure distribution on the bottom of the water pipe more uniform, and avoiding the rupture of the water pipe caused by pressure concentration. In the case of uneven ground, the first step and the second step can bear the stress of the water pipe due to ground settlement, and at the same time, it can also prevent the water pipe from directly contacting the ground, avoiding damage to the water pipe by sharp objects or sundries on the ground. In addition, under the impact of water flow, the first step and the second step can reduce the direct impact of water pressure on the bottom of the water pipe, extending the service life of the water pipe.

[0019] Preferably, the diameter of the water pipe near the water inlet side is the same as the diameter of the sewage pipe, the diameter of the water pipe near the water outlet side is the same as the diameter of the pump body water inlet pipe, and the diameter of the water pipe near the water outlet side is smaller than the diameter of the water pipe near the water inlet side.

[0020] By adopting the above device, by ensuring that the diameter of the water pipe near the water inlet side is the same as the diameter of the sewage pipe, and the diameter of the water pipe near the water outlet side is the same as the diameter of the pump body water inlet pipe, the resistance of the fluid in the pipeline system can be reduced, which helps to maintain the uniformity of the fluid flow rate, reduce the generation of turbulence and eddy currents, and improve the efficiency of fluid transportation. In addition, using pipes with the same diameter can simplify the installation process, reduce the adapters or conversion parts required for connecting pipes of different sizes, reduce material costs and installation costs, and the unified diameter is also convenient for maintenance and replacement.

[0021] The present application has the following beneficial effects:

[0022] 1. In the present application, by setting the first elbow and the second elbow, the bending degree of the water pipe is increased, which helps to improve the dynamic characteristics of the water flow, reduce the accumulation of sediments, and thus improve the filtration efficiency. In addition, the design of the fixing part allows for the quick disassembly and installation between the water pipe, the sewage pipe, and the lift pump, facilitating maintenance and cleaning, reducing maintenance costs and time, and at the same time improving the flexibility and adaptability of the filtration device, enabling it to adapt to different environments and requirements. The built-in design reduces the need for external filtration equipment, saves space, and reduces the complexity of the system.

[0023] 2. In the present application, by ensuring that the diameter of the water pipe near the water inlet side is the same as the diameter of the sewage pipe, and the diameter of the water pipe near the water outlet side is the same as the diameter of the pump body water inlet pipe, the resistance of the fluid in the pipeline system can be reduced, which helps to maintain the uniformity of the fluid flow rate, reduce the generation of turbulence and eddy currents, and improve the efficiency of fluid transportation. In addition, using pipes with the same diameter can simplify the installation process, reduce the adapters or conversion parts required for connecting pipes of different sizes, reduce material costs and installation costs, and the unified diameter is also convenient for maintenance and replacement.

[0028] The following further describes the present application in detail in conjunction with the attached Figure 1-2 drawings.

[0029] A built-in detachable filtration device in a double U-shaped pump body, as Figure 1-2 shown, includes a water pipe 1. The two ends of the water pipe 1 are respectively provided with a water inlet 11 and a water outlet 12. The water inlet 11 is connected to the upstream sewage pipe, and the water outlet 12 is connected to a lift pump. A first elbow 13 and a second elbow 14 are arranged between the water inlet 11 and the water outlet 12, so that the entire water pipe 1 presents a double U-shaped structure, which not only effectively increases the filtration path but also improves the filtration effect. Fixing members 2 are arranged on the outer walls of the water pipe 1 near the water inlet 11 and the water outlet 12. Through the connection of the fixing members 2, the water pipe 1 is detachably connected between the sewage pipe network and the lift pump. A sealing member 3 is arranged inside the fixing member 2. When the fixing member 2 is connected, the fixing member 2 presses against the sealing member 3, so that the sealing member 3 closely adheres to the pipe wall of the water pipe 1 to ensure the sealing performance of the connection. Among them, in this embodiment, the fixing member 2 is a clamp, and the sealing member 3 is a rubber ring.

[0030] As Figure 1-2 shown, in this embodiment, in order to realize the flexible control of the water flow on and off, valves 4 are installed at both the water inlet 11 and the water outlet 12. The setting of the valves 4 can quickly cut off or restore the water flow when device maintenance is required or in case of an emergency.

[0031] In practical applications, when the filtration device needs to be cleaned or repaired, the water flow can be cut off by closing the valves 4, thereby ensuring the safety of the operation. At the same time, the setting of the valves 4 also enables local maintenance of the device without affecting the normal operation of other parts.

[0032] Under normal working conditions, the valve 4 is in an open state, and sewage can pass through the filter device smoothly. When maintenance or cleaning is required, the corresponding valve 4 is closed to cut off the water flow in that part, and then the corresponding operation is performed, which ensures the safety of operation and improves the flexibility and efficiency of the device.

[0033] In order to further improve the convenience of maintenance, a fastener 41 is also provided on the outside of the valve 4. The fastener 41 and the valve 4 are detachably connected, so that the valve 4 can be quickly and non-destructively removed or replaced when necessary, simplifying the on-site maintenance process. In this embodiment, the fastener 41 is a round hexagonal bolt, which is used for anchoring and fixing.

[0034] like Figure 1-2 As shown, in this embodiment, a supporting part 5 is cast at the bottom of the water pipe 1, and the supporting part 5 includes a first step 51 and a second step 52. The first step 51 is located at the bottom of the water inlet 11, and the second step 52 is located at the bottom of the water outlet 12. The first step 51 and the second step 52 both play a supporting role, which can effectively support the water pipe 1, so that the pressure distribution on the bottom of the water pipe 1 is more uniform, avoiding the situation that the water pipe 1 is broken due to the concentration of pressure, and extending the service life of the water pipe 1.

[0035] like Figure 1-2 As shown, in this embodiment, in terms of specific pipe diameter design, the pipe diameter on the water inlet 11 side of the water pipe 1 is consistent with the pipe diameter of the sewage pipe, while the pipe diameter on the side of the water pipe 1 close to the water outlet 12 is adjusted to match the pipe diameter of the water inlet 11 of the lift pump, which can adapt to different flow requirements, so that the system can maintain good performance under different working conditions. In addition, the pipe diameter on the side of the water pipe 1 close to the water outlet 12 is smaller than the pipe diameter on the side of the water inlet 11 of the water pipe 1, which helps the pump body to inhale fluid more efficiently, reduce suction resistance, and improve the working efficiency of the pump body.

[0036] Working principle: When sewage flows into the water pipe 1 from the water inlet 11, it flows through a certain path in the double U-shaped structure. During this period, the heavier impurities are deposited at the bottom of the pipe due to gravity, while the lighter impurities continue to move forward with the water flow. When the sewage flows to the water outlet 12, most of the impurities have been filtered out, thereby ensuring that the impurity content of the sewage entering the lift pump is greatly reduced. When the filter device needs to be cleaned or maintained, the water pipe 1 can be easily removed from the sewage network and the lift pump by simply removing the fixing 2. The operation is simple and quick.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
