Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging equipment technology, and more specifically, to a device for accelerating the flow of media in a pipeline. Background Technology

[0002] When water-containing sludge and waste liquid flow in pipelines for extended periods, the high viscosity of the wastewater causes suspended solids to settle easily, resulting in slow sludge flow and reduced fluidity. This is especially true for sludge pipelines operating intermittently, which frequently experience blockages due to sludge settling and drying. Simultaneously, a large amount of impurities in the waste liquid settles at the bottom of the pipeline, reducing the pipeline's diameter and making it prone to flow obstruction. Utility Model Content

[0003] The purpose of this invention is to provide a device that accelerates the flow of media in a pipeline, which solves the problems of blockage and poor flow caused by sludge settling and drying in existing sludge pipelines.

[0004] This utility model is achieved through the following technical solution: a device for accelerating the flow of a medium in a pipeline, comprising an installation pipe, a rotating shaft rotatably disposed inside the installation pipe, both ends of the rotating shaft extending out of the installation pipe, and a plurality of driving blades arranged around the portion of the rotating shaft located inside the installation pipe.

[0005] A driving component is provided outside the installation pipe. The driving component is connected to one end of the rotating shaft. When the sewage flows from left to right in the installation pipe, the driving component drives the rotating shaft to rotate counterclockwise. When the sewage flows from right to left in the installation pipe, the driving component drives the rotating shaft to rotate clockwise.

[0006] Furthermore, the rotating shaft is arranged radially along the mounting tube, and the rotating shaft is arranged horizontally inside the mounting tube.

[0007] Furthermore, the drive blade has two blades, and the included angle between the two drive blades is 180°.

[0008] Furthermore, a rotary handle is provided at the end of the rotating shaft away from the driving member, and a scale bar is provided on the rotary handle, the scale bar being parallel to the driving blade.

[0009] Furthermore, it also includes a locking pin. The rotary handle is provided with a pin hole, and the mounting tube is provided with a locking hole. When the scale bar is rotated to a state parallel to the axis of the mounting tube, the pin hole and the locking hole are aligned. The locking pin is inserted into the pin hole and the locking hole at the same time to keep the two drive blades parallel to the axis of the mounting tube.

[0010] Furthermore, it also includes a water injection pipe, and a plurality of water injection pipes are connected to the installation pipe, and a solenoid valve is provided on the water injection pipe.

[0011] Furthermore, the driving component is a motor.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0013] 1. When the pipe becomes blocked, first open the solenoid valve. High-pressure water enters the installation pipe through the water injection pipe. The high-pressure water entering from the bottom of the installation pipe can disperse some of the deposited suspended matter. The high-pressure water flushes away the suspended matter and other impurities accumulated at the bottom of the installation pipe, causing them to resuspend in the water. Then start the motor. The motor drives the shaft to rotate through the coupling, which in turn drives the drive blades to rotate. When the drive blades rotate to the lowest point, the rotation direction is the same as the medium flow direction. Under the driving force of the drive blades, the accumulated sludge is pushed forward. The high-pressure water improves the water content of the sludge while generating impact force, making the internal sewage easier to flow. Combined with the driving force of the drive blades, this allows impurities to be discharged from the pipe more quickly.

[0014] 2. When the sewage flow in the installation pipe is normal, that is, when the pipe is not blocked and there is no need to drive the sewage with the drive blades, the shaft can be driven to rotate by the handle of the rotating wheel, so that the scale bar is parallel to the installation pipe, and thus the two drive blades are parallel to the direction of sewage flow. The drive blades do not interfere with the sewage flow, and thus will not reduce the flow rate of the internal sewage medium. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 3 As shown, this embodiment provides a device for accelerating the flow of a medium in a pipeline. This device is suitable for pipelines in a gravity flow state, rather than pressure pipelines. It mainly includes an installation pipe 1, which is usually set almost horizontally. In order to ensure that sewage flows in the installation pipe 1, the installation pipe 1 will have a certain slope when it is installed. The sewage pipes at both ends of the installation pipe 1 are also set with a certain slope to ensure that the sewage can flow smoothly.

[0023] like Figure 1 As shown, a rotating shaft 2 is rotatably installed inside the installation pipe 1. Several driving blades 3 are arranged around the portion of the rotating shaft 2 inside the installation pipe 1. The rotating shaft 2 is usually arranged radially along the installation pipe 1, and thus the rotating shaft 2 intersects the axis of the installation pipe 1. Furthermore, the rotating shaft 2 is usually arranged horizontally inside the installation pipe 1. Both ends of the rotating shaft 2 extend out of the installation pipe 1. A driving component 4 is provided outside the installation pipe 1. The driving component 4 is a motor or a reducer. The driving component 4 is connected to one end of the rotating shaft 2 through transmission, and thus drives the rotating shaft 2 to rotate, which in turn drives the several driving blades 3 to rotate. When the driving blades 3 rotate, the driving blades 3 act on the sewage, making it difficult for suspended solids in the sewage to settle.

[0024] More specifically, such as Figure 1As shown, due to gravity, suspended solids in sewage usually settle at the bottom of the installation pipe 1. To ensure that the driving blades 3 can act on the sludge deposited at the bottom of the installation pipe 1 when the rotating shaft 2 rotates, from a horizontal perspective, when the sewage flows from left to right in the installation pipe 1, the driving component 4 drives the rotating shaft 2 to rotate counterclockwise; when the sewage flows from right to left in the installation pipe 1, the driving component 4 drives the rotating shaft 2 to rotate clockwise. Under the premise of ensuring that the rotating shaft 2 is perpendicular to the internal sewage flow direction, the driving blades 3 are aligned with the sewage flow direction when rotating from top to bottom in the installation pipe 1 to the lowest point. This effectively drives and agitates the sewage, making it less likely for suspended solids in the sewage to settle.

[0025] More specifically, such as Figures 1-3 As shown, there are two drive blades 3, with an included angle of 180° between them. At the same time, a rotary handle 5 is provided at the end of the rotating shaft 2 away from the drive component 4. A scale bar 51 is provided on the rotary handle 5, which is parallel to the drive blades 3. A baseline 12 is also provided on the mounting pipe 1, which is on the same plane as the rotating shaft 2. When the sewage flow in the mounting pipe 1 is normal, that is, when the pipe is not blocked and the drive blades 3 are not needed to drive the sewage, the rotating shaft 2 can be driven to rotate by the rotary handle 5, so that the scale bar 51 is parallel to the baseline 12 on the mounting pipe 1. This makes the two drive blades 3 parallel to the direction of sewage flow, and the drive blades 3 do not interfere with the sewage flow, thus not reducing the flow rate of the internal sewage medium. At the same time, the driving ability of two drive blades 3 is better than that of one.

[0026] More specifically, such as Figures 1-3 As shown, it also includes a locking pin 6, a pin hole 52 on the rotary handle 5, and a locking hole 11 on the mounting tube 1. When the scale bar 51 is rotated to a state parallel to the axis of the mounting tube 1, the pin hole 52 and the locking hole 11 are aligned. By inserting the locking pin 6 into both the pin hole 52 and the locking hole 11, the two drive blades 3 are kept parallel to the axis of the mounting tube 1. Thus, when the sewage medium flows, the drive blades 3 cannot be deflected. The fixed drive blades 3 are in the same direction as the sewage flow and do not affect the sewage flow. Of course, if the motor or reducer has the function of automatically adjusting the drive blades 3 to be parallel to the sewage flow direction and has a self-locking function, then the rotary handle 5 and the locking pin 6 are not needed, which may increase the cost. The specific choice depends on the actual use needs. For long-distance pipelines that are inconvenient to maintain, a motor with a self-locking function can be used. For short-distance pipelines that are easy to maintain, manual adjustment can be made by manually adjusting the drive blades through the rotary handle 5.

[0027] More specifically, such as Figure 1 and Figure 3As shown, it also includes a water injection pipe 7. Several water injection pipes 7 are connected to the installation pipe 1, and a solenoid valve 71 is installed on the water injection pipe 7. In specific implementation, the several water injection pipes 7 are arranged at intervals. The water injection pipes 7 are usually connected to the bottom of the installation pipe 1. When the pipe is blocked, the solenoid valve 71 is opened first, and high-pressure water enters the installation pipe 1 through the water injection pipe 7. The high-pressure water entering from the bottom of the installation pipe can dissipate some of the deposited suspended matter. The high-pressure water flushes the suspended matter and other impurities accumulated at the bottom of the installation pipe 1, so that they are resuspended in the water. Then the motor is started. The motor drives the rotating shaft 2 to rotate through the coupling, which in turn drives the drive blade 3 to rotate. When the drive blade 3 rotates to the lowest point, the rotation direction is the same as the medium flow direction. Under the driving force of the drive blade 3, the accumulated sludge is pushed forward. The high-pressure water improves the water content of the sludge while generating impact force, making the internal sewage easier to flow. Combined with the driving force of the drive blade 3, the impurities are discharged from the pipe more quickly.

[0028] In summary, this device can accelerate the flow rate of the medium within the installation pipe 1, thereby increasing the throughput. This is applicable to non-pressure pipelines. Considering the potential for a rapid increase in the amount of medium flowing through the pipeline within a certain timeframe, and limitations imposed by factors such as fluid velocity, pipe material, pipe diameter, and fill factor, the medium may not be able to flow out within a specified time. Adding this device at regular intervals along the pipeline can accelerate the flow rate. Furthermore, this device can remove sediment buildup at the bottom of the pipe. Installing this device in areas prone to sediment buildup, as well as on long-distance pipelines, and periodically activating it can prevent pipe sedimentation.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
