[0001] This application relates to the field of fluid machinery, and in particular to a drainage pump. Background Technology

[0002] In industrial production and fluid handling, it is often necessary to mix, transport, and lift different substances, especially in industries such as oil extraction, chemical production, and wastewater treatment. As an important fluid transport device, the diversion pump has a suction function, utilizing the principle of diversion to draw in high-velocity liquids and accelerate the flow of low-velocity liquids. However, the characteristics of the fluids and the transport requirements vary in different application scenarios, and traditional diversion pumps have limited adaptability. When the transported fluid contains a large number of solid particles or impurities, the diversion pump is prone to clogging, leading to pump damage or reduced operating efficiency.

[0003] Currently, in related technologies, drainage pumps are prone to clogging, leading to reduced working efficiency. Summary of the Invention

A small oil pipe connector is located inside the oil pipe connector and at the output end of the inner channel. When the oil pipe connector is connected to a high-pressure pipeline and the small oil pipe connector is connected to an oil pipe, a hydraulic fluid inlet is formed in the outer channel. The hydraulic fluid transported by the high-pressure pipeline flows through the hydraulic fluid inlet. The liquid inlet is supplied to the outer channel; a driving stirring device is located at the other end of the main body of the dredging pump, and the driving stirring device is connected to the outer channel through a straight port. The driving stirring device enters through the straight port and drives the driving stirring device to rotate, disturbing the stagnant matter to form a mixture; an ejector is located at the output end of the driving stirring device. The driving stirring device outputs the driving stirring device and is transmitted to the ejector to form a high-speed jet. The high-speed jet forms a negative pressure zone, which draws the mixture into the ejector. The mixture then flows through the inner channel to the mixture outlet formed by the small oil pipe joint, lifting and outputting the mixture.

[0006] Preferably, the ejector includes: a guide, which is disposed at the output end of the driving stirring device; a nozzle, which is connected to the guide, through which the motive fluid is guided to the large inlet of the nozzle and output through the small nozzle to form a high-speed jet; a guide tube, which is disposed at the small nozzle end of the nozzle and connected to the diffuser head, for guiding and outputting the mixture drawn into the ejector; and a guide, which is connected to the guide tube, for guiding the fluid flow of the mixture and transporting the mixture to the inner channel.

[0007] Preferably, the drainage pump further includes a negative pressure suction port, which is disposed on the main body of the drainage pump. When the negative pressure zone is formed, the stagnant material in the formation is sucked into the negative pressure zone through the negative pressure suction port. The driving stirring device rotates and disturbs the stagnant material to form a mixture. After the mixture is guided by the drainage device, it is mixed with the power fluid and the flow rate is increased. Then, it is drained out through the drainage pipe.

[0008] Preferably, the driving stirring device includes: a rotary water motor, which is fixed inside the main body of the diversion pump by a water motor bracket, and the rotary water motor is provided with an inclined discharge hole. After the power fluid flows through the rotary water motor, it is discharged through the inclined discharge hole and drives the central shaft of the rotary water motor to rotate; and a stirrer, which is fixedly connected to the rotary water motor by the central shaft. When the central shaft rotates, it drives the stirrer to rotate, disturbing the retained material to form a mixture.

[0009] Preferably, the tilt angle of the tilted discharge port of the rotary water motor is greater than 70°.

[0010] Preferably, the drainage pump further includes a rotating sealing sleeve, which is coaxially mounted with the central shaft and used to seal the central shaft.

[0011] Preferably, the drainage pump further includes a small oil pipe reducer, which is located behind the small oil pipe joint and is used to connect the oil pipe with the small oil pipe joint.

[0012] Preferably, the pump further includes an impurity filter, which is disposed in the outer channel and is used to filter impurities in the power fluid in the outer channel.

[0014] This application provides a diversion pump, comprising: a pump body, wherein the pump body has an outer channel and an inner channel, the outer channel being used for the transmission of high-pressure hydraulic fluid, and the inner channel being used for conveying a mixture; and an oil pipe connector, which is located at one end of the pump body and at the input end of the outer channel, communicating with the outer channel. A small oil pipe connector is located inside the oil pipe connector at the output end of the inner channel. When the oil pipe connector is connected to a high-pressure pipeline and the small oil pipe connector is connected to an oil pipe, a hydraulic fluid inlet is formed in the outer channel, and the hydraulic fluid transported by the high-pressure pipeline is conveyed through the hydraulic fluid inlet. The fluid is fed into the outer channel; a driving stirring device is located at the other end of the main body of the pump, and the driving stirring device is connected to the outer channel through a straight port. The driving stirring device is driven to rotate through the straight port, disturbing the retained matter and forming a mixture; an ejector is located at the output end of the driving stirring device.

The high-speed jet creates a negative pressure zone, drawing the mixture into the ejector. The mixture then flows through the inner channel to the mixture outlet formed by the small oil pipe joint, lifting and outputting the mixture. This solves the technical problem of easy clogging of the pump in the prior art, which leads to reduced working efficiency, and achieves the technical effect of reducing the risk of clogging and improving working efficiency.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 As shown in the figure, this application embodiment provides a drainage pump, the drainage pump comprising:

[0026] The pump body includes an outer channel and an inner channel. The outer channel is used for the transmission of high-pressure hydraulic fluid, and the inner channel is used for transporting a mixture. An oil pipe connector 1 is located at one end of the pump body and is situated at the input end of the outer channel, communicating with it. A small oil pipe connector 17 is located inside the oil pipe connector 1 and is situated at the output end of the inner channel. When the oil pipe connector 1 is connected to the high-pressure pipeline and the small oil pipe connector 17 is connected to the oil pipe, a hydraulic fluid inlet 19 is formed in the outer channel. The hydraulic fluid transported by the high-pressure pipeline is then transported to the outer channel via the hydraulic fluid inlet 19. Inside the channel; a driving stirring device is located at the other end of the main body of the diversion pump, and the driving stirring device is connected to the outer channel through a straight port. The power fluid enters the driving stirring device through the straight port, driving the driving stirring device to rotate and disturbing the stagnant matter to form a mixture; an ejector 16 is located at the output end of the driving stirring device. The power fluid output by the driving stirring device is transmitted to the ejector 16 and forms a high-speed jet. The high-speed jet forms a negative pressure zone, which draws the mixture into the ejector 16. The mixture flows through the inner channel to the mixture outlet 18 formed by the small oil pipe joint 17, and the mixture is lifted and output.

[0027] Specifically, the diversion pump mainly consists of four key parts: the diversion pump body, the oil pipe joint 1, the drive stirring device, and the ejector 16. Each part plays a specific role, working together to achieve efficient and stable mixture delivery.

[0028] Specifically, the pump body is designed with an outer channel and an inner channel. The outer channel is responsible for the transmission of high-pressure hydraulic fluid, while the inner channel is used to transport the mixture. The inner channel is a pipe inside the ejector 16 used to transport the mixture. Through the synergistic effect of these two channels, the input of hydraulic fluid and the output of the mixture are realized.

[0029] The oil pipe connector 1 is located at one end of the main body of the dredging pump and is connected to the input end of the outer channel. Inside the oil pipe connector 1, there is also a small oil pipe connector 17, which is connected to the output end of the inner channel. When the oil pipe connector 1 is connected to the high-pressure pipeline and the small oil pipe connector 17 is connected to the oil pipe, the outer channel forms a power fluid inlet 19. In this way, the power fluid transported by the high-pressure pipeline can smoothly enter the outer channel.

[0030] The driving agitator is located at the other end of the priming pump body and is connected to the external channel through a straight port. After the motive fluid enters the driving agitator through the straight port, it drives the agitator to rotate. This rotational motion can disturb the stagnant matter and form a mixture that is easy to transport.

[0031] The driving stirring device can be replaced by a rotary jetting device, such as... Figures 4-5 As shown, the rotary jet device is located at the other end of the main body of the pump, and the rotary jet device is connected to the external channel through a straight port. After the power fluid enters the rotary jet device through the straight port, it passes through a cylindrical structure 20. The bottom of the cylindrical structure 20 is a conical structure 21, and the tip of the conical structure 21 is provided with a guide hole 22 (e.g., with a diameter of 6 mm). The power fluid enters the interior of the cylindrical structure 20 through the guide hole 22. The side wall of the cylindrical structure 20 is provided with a gradually expanding jet port 23 (e.g., four ports can be provided). The gradually expanding jet port 23 is composed of two cylinders with different diameters. The diameter of the inlet cylinder 24 is smaller than the diameter of the outlet cylinder 25 (e.g., the inlet diameter is 1.1 mm and the outlet diameter is 2 mm) and has an inclined angle, so that the power fluid can be ejected in a rotating tangential jet manner when passing through the gradually expanding jet port 23, forming a rotating tangential jet. Rotating shear jets have a strong disturbance force, which can disturb the sand, cement, coal slurry and other stagnant materials in front of them, forming a mixture that is easy to transport.

[0032] The ejector 16 is located at the output end of the driving agitator. The kinetic fluid output from the driving agitator is transmitted to the ejector 16, forming a high-speed jet. This high-speed jet creates a negative pressure zone inside the ejector 16, drawing the mixture into it. Subsequently, the mixture flows through the inner channel to the mixture outlet 18 formed by the small tubing connector 17, where it is lifted and output for use in the extraction of natural gas wells, coalbed methane wells, shale gas wells, etc.

[0033] Preferred, such as Figure 3 As shown, the ejector 16 includes: a guide 6, which is located at the output end of the driving stirring device; a nozzle 4, which is connected to the guide 6, through which the driving fluid is guided to the large inlet of the nozzle 4 and output through the small nozzle to form a high-speed jet; a guide pipe 14, which is located at the small nozzle end of the nozzle 4 and connected to the diffuser head 13, for guiding and outputting the mixture drawn into the ejector 16; and a guide 15, which is connected to the guide pipe 14, for guiding the fluid flow of the mixture and transporting the mixture to the inner channel.

[0034] Specifically, in the preferred design, the ejector 16 includes four main parts: an ejector 6, a nozzle 4, an ejector tube 14, and a guide tube 15.

[0035] The guide 6 is set at the output end of the driving stirring device via the guide fixing bracket 12, receiving and guiding the power fluid output by the driving stirring device to ensure that the power fluid can enter the nozzle 4 smoothly and efficiently.

[0036] Nozzle 4 is connected to the inlet 6 and has a large inlet and a small nozzle. The large inlet receives the motive fluid guided by the inlet 6, and the small nozzle outputs a high-speed jet stream. After being guided by the inlet 6, the motive fluid enters the large inlet of nozzle 4. Inside nozzle 4, the motive fluid is accelerated and output as a high-speed jet stream from the small nozzle. This high-speed jet stream creates a negative pressure zone around nozzle 4, thereby enabling the intake of mixtures, including sand, coal dust, coal slurry, water, gas, etc.

[0037] A drainage tube 14 is located at the small nozzle end of the nozzle 4 and connected to the diffuser head 13 to receive the mixture flowing out of the diffuser head 13. The drainage tube 14 is used to guide the mixture drawn into the ejector 16, ensuring that the mixture can smoothly enter the drainage tube 14 from the nozzle 4. After the mixture enters the drainage tube 14, the longer the drainage tube 14, the stronger the drainage capacity. The larger the negative pressure zone formed between the inlet of the drainage tube 14 and the nozzle 4, the stronger the liquid suction capacity, which can quickly lift mixtures such as gas, water, and sand to the ground through the drainage tube 14.

[0038] The flow guide 15 is connected to the flow pipe 14. The flow guide 15 is responsible for guiding the fluid flow of the mixture, ensuring that the mixture can flow along a predetermined path and is eventually delivered to the inner channel.

[0039] By introducing components such as the diverter 6, nozzle 4, divert tube 14, and guide tube 15, the ejector 16 section of this diverting pump has been significantly optimized. These components work together to achieve functions such as acceleration of the motive fluid, suction and delivery of the mixture. This design not only improves the operating efficiency of the diverting pump but also enhances its stability and reliability.

[0040] Preferably, the drainage pump further includes a negative pressure suction port 5, which is disposed on the main body of the drainage pump. When the negative pressure zone is formed, the stagnant material in the formation is sucked into the negative pressure zone through the negative pressure suction port 5. The driving stirring device rotates and disturbs the stagnant material to form a mixture. After the mixture is guided by the drainage device 6, it is mixed with the power fluid and the flow rate is increased. Then, it is drained out through the drainage pipe 14.

[0041] Specifically, the drainage pump can be used to treat deposits in the formation. A negative pressure suction port 5 is located on the main body of the drainage pump and is connected to the formation or the area to be treated. For example, the negative pressure suction port 5 can be specifically a negative pressure chamber inlet. When the kinetic fluid output from the driving agitator is transmitted to the ejector 16, a high-speed jet stream is formed, creating a negative pressure zone. When a negative pressure zone is formed inside the ejector 16, the negative pressure suction port 5 plays a crucial role, allowing the deposits in the formation to be effectively drawn into the negative pressure zone, mixed with the kinetic fluid, and then drained through the drainage pipe 14 after increasing the flow rate. The kinetic fluid enters the driving agitator through the straight-through port, causing it to rotate, thereby agitating the deposits and forming an easily transportable mixture. This design not only improves the suction efficiency of the drainage pump but also ensures that the deposits are treated thoroughly and uniformly.

[0042] Preferred, such as Figure 2 As shown, the driving stirring device includes: a rotary water motor 11, which is fixed inside the main body of the diversion pump by a water motor bracket 7, and the rotary water motor 11 is provided with an inclined discharge hole. After the power fluid flows through the rotary water motor 11, it is discharged through the inclined discharge hole and drives the central shaft 9 of the rotary water motor to rotate; and a stirrer 8, which is fixedly connected to the rotary water motor 11 by the central shaft 9. When the central shaft 9 rotates, it drives the stirrer 8 to rotate, disturbing the retained material to form a mixture.

[0043] Specifically, the driving agitator is a key component of the diversion pump, responsible for converting the kinetic fluid into mechanical energy, thereby disturbing the deposits in the formation and forming a mixture that is easy to transport. In a preferred design, the driving agitator comprises two main parts: a rotary water motor 11 and an agitator 8.

[0044] The rotary water motor 11 is securely fixed inside the pump body by the water motor bracket 7. This design ensures that the rotary water motor 11 remains stable during operation and will not be damaged by vibration or impact. The rotary water motor 11 is equipped with inclined discharge holes, preferably eight in number. When the motive fluid flows through the rotary water motor 11, it is discharged through these inclined discharge holes at a certain angle and speed. This design not only improves the utilization efficiency of the motive fluid but also enables the rotary water motor 11 to generate greater torque and rotational speed. Its working principle is as follows: when the motive fluid flows through the rotary water motor 11, it exerts a force on its internal blades, thereby driving the central shaft 9 of the rotary water motor 11 to rotate. In this process, the kinetic energy of the motive fluid is converted into mechanical energy, providing power for subsequent stirring operations.

[0045] The agitator 8 is fixedly connected to the rotary water motor 11 via a central shaft 9. The agitator 8 can be plate-shaped with a diameter smaller than that of the main body of the diverter 6. This design ensures that the agitator 8 can rotate synchronously with the rotary water motor 11, and the up-and-down process is less prone to obstruction. When the central shaft 9 rotates, the agitator 8 will also rotate accordingly. During rotation, the blades of the agitator 8 will disturb the sediment in the formation, forming a mixture that is easy to transport (e.g., a mixture of gas, liquid, and sand).

[0046] By incorporating the preferred design of a rotary water motor 11 and an agitator 8, the driving and stirring device can more efficiently convert kinetic fluid into mechanical energy and agitate deposits in the formation to form a mixture. The inclined discharge port design of the rotary water motor 11 improves the utilization efficiency of the kinetic fluid and enables the rotary water motor 11 to generate greater torque and rotational speed. The agitator 8 is fixedly connected to the rotary water motor 11 via a central shaft 9, ensuring that the agitator 8 rotates synchronously with the rotary water motor 11, thereby efficiently handling deposits. This design not only improves the working efficiency of the diversion pump but also enhances its stability and reliability.

[0047] Preferably, the tilt angle of the tilted discharge hole of the rotary water motor 11 is greater than 70°.

[0048] Specifically, in a preferred design, the inclined discharge port of the rotary water motor 11 is designed with an inclination angle greater than 70°. Setting the inclined discharge port at an angle greater than 70° allows for more efficient guidance of the motive fluid out of the rotary water motor 11. This design helps reduce energy loss of the motive fluid during the outflow process, thereby improving its utilization efficiency.

[0049] When the motive fluid flows out at a larger angle, it generates a greater impact force on the blades of the rotary water motor 11. This impact force can be converted into greater torque and rotational speed, enabling the rotary water motor 11 to drive the agitator 8 to rotate more effectively.

[0050] When the motive fluid flows out at a larger angle, it drives the agitator 8 to rotate in a more uniform and stable manner. This rotation method can more effectively disturb the deposits in the formation, forming a more uniform and easier-to-transport mixture. This design not only improves the utilization efficiency of the motive fluid and enhances torque and rotation speed, but also optimizes the stirring effect, enabling the diversion pump to process the deposits in the formation more efficiently and stably.

[0051] Preferably, the drainage pump further includes a rotating sealing sleeve 10, which is coaxially mounted with the central shaft 9 and is used to seal the central shaft 9.

[0052] Specifically, the rotating seal sleeve 10 is coaxially mounted with the central shaft 9, tightly wrapping around the outside of the central shaft 9. This design ensures that the rotating seal sleeve 10 effectively seals the central shaft 9, preventing fluid leakage from the gap between the central shaft 9 and the pump body. The rotating seal sleeve 10 is made of wear-resistant and corrosion-resistant materials to ensure stable sealing performance during long-term operation. When the central shaft 9 rotates, the rotating seal sleeve 10 rotates accordingly, but its internal sealing structure remains stationary, forming a dynamic sealing interface. This interface effectively prevents fluid from passing through, ensuring that the fluid inside the pump does not leak into the external environment. Simultaneously, the rotating seal sleeve 10 also protects the central shaft 9 from fluid erosion and wear, extending the service life of the pump.

[0053] Preferably, the drainage pump further includes a small oil pipe reducer 2, which is located behind the small oil pipe connector 17 and is used to connect the oil pipe with the small oil pipe connector 17.

[0054] Specifically, the small tubing reducer 2 is designed with two ends of different diameters. One end connects to the small tubing connector 17, and the other end connects to another tubing. This design allows the small tubing reducer 2 to act as a transition piece, connecting tubing of different diameters. The existence of the small tubing reducer 2 makes tubing connections more flexible and diverse, adapting to the connection needs between tubing of different diameters. This ensures that the tubing in the pump system can smoothly transmit fluid, providing strong support for its flexibility and versatility in practical applications.

[0055] Preferably, the pump further includes an impurity filter 3, which is disposed in the outer channel and is used to filter impurities in the power fluid in the outer channel.

[0056] Specifically, the impurity filter 3 can be designed as a cylindrical or box-shaped structure, filled with filter media (such as filter screens, filter elements, etc.). It is installed in the external channel, perpendicular or parallel to the flow direction of the power fluid, to effectively filter impurities in the power fluid.

[0057] When the power fluid flows through the impurity filter 3, impurities are blocked by the filter medium and remain inside the filter, while the pure power fluid continues to flow to subsequent components. The pore size of the filter medium can be adjusted according to actual needs to filter out impurities of different sizes.

[0058] The impurity filter 3 effectively filters out impurities in the power fluid, preventing these impurities from causing wear or blockage to components such as the impeller and bearings of the expedited pump. Furthermore, the impurity filter 3 also improves the purity of the power fluid, thereby ensuring the working efficiency and stability of the expedited pump.

[0059] The technical solutions provided in this application have at least the following technical effects or advantages:

[0060] This application provides a diversion pump, comprising: a diversion pump body, wherein the diversion pump body is provided with an outer channel and an inner channel, the outer channel being used for the transmission of high-pressure hydraulic fluid, and the inner channel being used for conveying a mixture; an oil pipe connector 1, wherein the oil pipe connector 1 is disposed at one end of the diversion pump body and is located at the input end of the outer channel and communicates with the outer channel, and a small oil pipe connector 17 is disposed inside the oil pipe connector 1, wherein the small oil pipe connector 17 is located at the output end of the inner channel, and when the oil pipe connector 1 is connected to a high-pressure pipeline and the small oil pipe connector 17 is connected to an oil pipe, a hydraulic fluid inlet 19 is formed in the outer channel, and the hydraulic fluid transported by the high-pressure pipeline passes through the hydraulic fluid inlet 19. The fluid is delivered to the outer channel; a driving stirring device is located at the other end of the main body of the pump, and the driving stirring device is connected to the outer channel through a straight port. The driving fluid enters the driving stirring device through the straight port, driving the driving stirring device to rotate and agitate the retained substances to form a mixture; an ejector 16 is located at the output end of the driving stirring device. The driving fluid output by the driving stirring device is transmitted to the ejector 16 and forms a high-speed jet. The high-speed jet creates a negative pressure zone, drawing the mixture into the ejector 16. The mixture then flows through the inner channel to the mixture outlet 18 formed by the small oil pipe joint 17, where it is lifted and output. This achieves the technical effect of reducing the risk of blockage and improving working efficiency.
