[0040] Please see Figures 1-2 As shown, Figure 1 This is a schematic diagram of the external structure of the ultrafiltration pump with a spiral water inlet pipe according to an embodiment of the present utility model. Figure 2 This is a schematic diagram of the internal connections of an ultrafiltration pump with a spiral inlet pipe according to an embodiment of the present invention; the monitoring component, cleaning component, and control component are not shown in the diagram. Specifically, the present invention provides an ultrafiltration pump with a spiral inlet pipe, comprising:

[0041] Water inlet pipe 1, one end of which is connected to an external sewage tank or external sewage pipe, and the other end is screwed to the inlet of pump body 3;

[0042] Motor 2 is located on one side of pump body 3 and is connected to rotating assembly inside pump body 3 via transmission assembly to drive rotating assembly to rotate;

[0043] Pump body 3, the pump body 3 comprising:

[0044] The pump body 3 has an inlet 301 and an outlet 302. The inlet 301 is threadedly connected to the inlet pipe 1 and is used to draw sewage from the inlet pipe 1 through the inlet 301. After treatment, the sewage is discharged into the pump body 3 through the outlet 302.

[0045] A rotating component is used to effectively transport wastewater to the filter component 304 through its own rotational motion;

[0046] The filter assembly 304 is disposed at the connection between the inlet pipe 1 and the pump body 3 and on the side near the outlet 302 of the pump body 3, for filtering the sewage.

[0047] The monitoring components are installed at several locations at the inlet and outlet of the water inlet pipe 1, the pump body 3, and the filter assembly 304 to monitor sewage flow rate, sewage turbidity, and sewage pressure data in real time.

[0048] It is understandable that, through the reasonable structural design and component configuration of the pump body 3, motor 2, and inlet pipe 1, the ultrafiltration pump of this utility model can effectively filter and transport sewage. At the same time, it can intelligently adjust the relevant parameters of the rotating component and the filter component 304 according to the actual situation of the sewage, thereby improving the efficiency and effect of sewage treatment.

[0049] In one specific embodiment, the ultrafiltration pump further includes a control component connected to the monitoring component for adjusting the rotational speed of the rotating component and the filtration rate of the filter component 304. The monitoring component may include a flow meter, a turbidity meter, and a pressure sensor. The flow meter measures the wastewater flow rate and is installed at the inlet of the inlet pipe 1 and the outlet of the pump body 3 to monitor the input and output flow rates of the wastewater. The turbidity meter measures the turbidity of the wastewater, i.e., the content of suspended solids in the wastewater, and is installed at the inlet or outlet of the filter component 304 to monitor changes in water quality before and after filtration. The pressure sensor measures the pressure of the wastewater in the pipeline and is installed at the inlet of the inlet pipe 1, the pump body 3, and the inlet and outlet of the filter component 304 to monitor pressure changes during the flow of the wastewater. The control component may be a PLC logic controller. In implementation, the relevant components of the monitoring and control components can be determined according to actual conditions, and are not specifically limited here, nor will they be described in detail.

[0050] This utility model, through the design of a spiral inlet pipe, intelligent monitoring and control components, and a high-efficiency filtration component 304, achieves efficient and precise filtration and transportation of sewage. It also enables adjustment of the rotation speed of the rotating component and the filtration rate of the filtration component 304, ensuring the stability and reliability of the ultrafiltration pump operation. This not only improves the efficiency and quality of sewage treatment but also enables intelligent management of the pump body 3.

[0051] Specifically, the inlet pipe 1 is spiral-shaped and includes at least three circular pipes to increase the turbulence of sewage within the inlet pipe 1.

[0052] Please see Figure 3 As shown, Figure 3 This is a first schematic diagram of a portion of the structure of the water inlet pipe 1 according to an embodiment of the present utility model. Specifically, a plurality of spiral strips 101 are evenly and equidistantly arranged on the inner wall of the water inlet pipe 1 to promote the turbulent flow of sewage in the water inlet pipe 1. The plurality of spiral strips 101 are in a continuous spiral shape.

[0053] Please see Figure 4 As shown, Figure 4 This is a second schematic diagram of a portion of the structure of the water inlet pipe 1 according to an embodiment of the present utility model; specifically, a plurality of guide plates 102 are evenly and equidistantly arranged on the inner wall of the water inlet pipe 1, and the shape of the guide plates 102 is arc-shaped.

[0054] Understandably, the design of the spiral inlet pipe 1 and the design of several spiral strips 101 / several guide plates 102 allow the sewage to continuously change its flow direction and velocity when flowing in the inlet pipe 1. At the same time, it effectively generates turbulence inside the inlet pipe 1. The turbulence can increase the collision frequency between the sewage and the inner wall of the inlet pipe 1 and between the sewage particles inside the sewage, which helps to disperse and suspend the particles, improve the particle removal efficiency, avoid particle deposition and blockage of the pipe, and at the same time help to improve the filtration efficiency of the filter component 304.

[0055] In one specific embodiment, there are three circular pipes and two spiral strips 101. In practice, the number of circular pipes and the number of spiral strips 101 can be determined according to the actual situation. No specific limitation is made here, and it will not be elaborated further.

[0056] In one specific embodiment, there are three circular pipes and six to ten guide plates 102. Preferably, there are eight guide plates 102. The installation position of the guide plates 102 can be determined according to the number of guide plates 102 and the length of the inlet pipe 1. The shape of the guide plates 102 is arc-shaped. In practice, the number of guide plates 102, the installation position of the guide plates 102, and the shape of the guide plates 102 can be determined according to the actual situation. No specific limitations are made here, nor will they be elaborated further.

[0057] In this utility model, the inlet pipe 1 adopts a spiral design, and several spiral strips 101 or several guide plates 102 are set inside the inlet pipe 1, which significantly increases the turbulence of sewage in the pipe 1, helps to break up the particle agglomeration in sewage, further improves the filtration efficiency of the subsequent filter component 304, and thus promotes the efficient operation of the sewage treatment process.

[0058] Specifically, the transmission component is a transmission shaft 305, one end of which is connected to the output shaft of the motor 2, and the other end is connected to the rotating component, so as to transmit the rotational power of the motor 2 to the rotating component inside the pump body 3.

[0059] Understandably, the drive shaft 305 serves to transmit rotational power, ensuring that the rotational power of the motor 2 can be smoothly and efficiently transmitted to the rotating components inside the pump body 3 and drive the rotating components to work. When the motor 2 starts, the motor 2 drives the output shaft to rotate, and the rotational power of the motor 2 is first transmitted to the drive shaft 305, and the rotation of the drive shaft 305 drives the rotating components to rotate.

[0060] In one specific embodiment, the transmission component is a coupling. The input shaft of the coupling is connected to the output shaft of the motor 2, and the output shaft of the coupling is connected to the rotating component, thereby transmitting the rotational power of the motor 2 to the rotating component inside the pump. In another specific embodiment, the transmission component is a gearbox. The gearbox includes at least one set of gears. The input shaft of the gears is connected to the output shaft of the motor 2, and the output shaft of the gears is connected to the rotating component. Power is transmitted through the meshing of the at least one set of gears to adjust the rotational speed between the motor 2 and the pump shaft inside the pump body 3. In practice, the configuration of the transmission component and the number of gear sets can be determined according to the actual situation, and are not specifically limited here, nor will they be elaborated further.

[0061] Specifically, the rotating component includes:

[0062] The spiral blade 3031 is sleeved on the output shaft of the transmission assembly. After being driven to rotate by the motor 2, it draws sewage into the pump body 3 and accelerates its discharge.

[0063] Bearing 3032, which is connected to the helical blade 3031, is used to support the rotation of the output shaft;

[0064] A bushing, which is fitted on the output shaft of the transmission assembly and connected to the bearing 3032, is used to reduce the friction between the output shaft, the bearing 3032, and the helical blade 3031.

[0065] Understandably, during the entire wastewater treatment process, bearing 3032 plays an important role in supporting the rotation of the output shaft, while the bushing is used to reduce the friction between the output shaft and bearing 3032 and spiral blade 3031. The presence of bearing 3032 and bushing improves the pump's operating efficiency and extends its service life.

[0066] Specifically, the filtration assembly 304 includes a plurality of ultrafiltration membrane units for filtering wastewater.

[0067] Specifically, it also includes a cleaning assembly disposed on one side of the plurality of ultrafiltration membrane units for cleaning dirt and blockages on the plurality of ultrafiltration membrane units. The cleaning assembly includes:

[0068] A high-pressure nozzle, connected to a cleaning pump, is used to spray water from the cleaning pump onto the plurality of ultrafiltration membrane units;

[0069] A cleaning pump, which provides the water flow and pressure required to clean the ultrafiltration membrane unit;

[0070] A control valve, connected to the high-pressure nozzle, is used to adjust the flow rate or pressure of the water.

[0071] Specifically, the cleaning assembly is equipped with a drain valve 306, and the opening and closing of the drain valve 306 controls the discharge of dirt and blockages during the sewage treatment process.

[0072] Understandably, the filter assembly 304 is used for efficient filtration of wastewater, and the cleaning assembly is used to clean the ultrafiltration membrane unit periodically or as needed to remove the dirt and blockages accumulated on the ultrafiltration membrane unit. At the same time, by setting the drain valve 306 and controlling the opening and closing of the drain valve 306, the timing and amount of dirt and blockage discharge can be precisely controlled.

[0073] In one specific embodiment, the number of ultrafiltration membrane units is 2 to 4, preferably 3; the cleaning component is a nozzle, which cleans the ultrafiltration membrane units at a certain spray speed and spray volume; in practice, the number of ultrafiltration membrane units and the type of cleaning component can be determined according to the actual situation, and are not specifically limited here, nor will they be elaborated further.

[0074] This utility model introduces a filter assembly 304 and a cleaning assembly into the ultrafiltration pump, achieving efficient filtration and regular cleaning of wastewater, effectively improving effluent quality and treatment efficiency. Simultaneously, the inclusion of a drain valve 306 allows for effective management of dirt and blockages generated during the cleaning process, extending the service life of the filter assembly 304 and thus promoting efficient wastewater treatment.

[0075] Specific work process:

[0076] Start-up phase: After receiving the start signal, motor 2 starts to rotate. The rotation of motor 2 drives the output shaft of the transmission component to rotate, which in turn drives the spiral blade 3031 to rotate together.

[0077] Wastewater treatment stage: The rotation of the spiral blade 3031 generates centrifugal force, which causes the wastewater to enter the pump body 3 through the inlet pipe 1. The wastewater flows along a specific path in the pump body 3 and passes through the filter assembly 304. The filter assembly 304 removes impurities and pollutants from the wastewater. The filtered wastewater is discharged from the outlet 302 of the pump body 3.

[0078] Adjustment phase: During the wastewater treatment process, the wastewater flow rate, turbidity, and pressure data are monitored in real time by the monitoring components. The rotation speed of the rotating components and the filtration rate of the 304 filter components are adjusted by the control components to improve the filtration effect.

[0079] Cleaning Phase: After a period of operation, some dirt and blockages may accumulate on the filter assembly 304, leading to a decrease in filtration efficiency. At this time, the cleaning assembly is activated to clean the ultrafiltration membrane unit. The dirt and blockages generated during the cleaning process will be discharged through the drain valve 306 near the cleaning assembly.

[0080] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
