Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, and in particular to a low-shear sinusoidal pump. Background Technology

[0002] A sinusoidal pump is a positive displacement rotor pump whose core working components are a pair of rotors with a sinusoidal profile. By rotating synchronously in opposite directions within the pump chamber, the volume of the pump chamber changes periodically, thereby achieving the intake and discharge of fluid.

[0003] Sine pumps are widely used in shear-sensitive fluid transportation scenarios such as food, medicine, and cosmetics due to their stable flow rate, low pulsation, and strong self-priming ability. They can effectively reduce the damage to the composition or structural changes of fluids during transportation.

[0004] Existing sinusoidal pumps have the following shortcomings:

[0005] Because the inlet and outlet pipes are fixedly connected to the pump body, when there is a slight deviation in the pipeline route, it is necessary to connect through elbows, which causes turbulence to be generated before the fluid enters the pump chamber, increasing the shear force. At the same time, the existing device lacks a refined fluid pretreatment and flow stabilization structure. Impurities and bubbles in the fluid can easily cause additional friction in the pump chamber, and the pressure fluctuations during discharge will have a reverse effect on the stability of the pump chamber and damage the fluid composition.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 ,Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a drive motor 1, a pump body 2 fixedly connected to the front end of the drive motor 1, the rotor of the pump body 2 fixedly connected to the output shaft of the drive motor 1, angle adjustment components 3 are provided on the top left and right sides of the outer surface of the pump body 2, an inlet pipe 4 is provided above the right angle adjustment component 3, and an outlet pipe 5 is provided above the left angle adjustment component 3. The angle adjustment component 3 includes an arc-shaped slide groove 31, two arc-shaped slide grooves 31 are opened on the left and right sides of the inner wall upper surface of the pump body 2, the middle part of the arc-shaped slide groove 31 extends to the outer surface of the pump body 2, an arc-shaped slide plate 32 is slidably connected to the inner surface of the arc-shaped slide groove 31, the inlet pipe 4 is fixedly connected to the top of the right arc-shaped slide plate 32 and communicates with the interior of the pump body 2, the outlet pipe 5 is fixedly connected to the top of the left arc-shaped slide plate 32 and communicates with the interior of the pump body 2, and arc-shaped slide grooves 31 are opened on the front and rear sides of the inner surface of the arc-shaped slide groove 31. The front and rear sides of the arc-shaped limiting groove 33 and the arc-shaped sliding plate 32 are fixedly connected to the arc-shaped limiting plate 34. The arc-shaped limiting plate 34 is slidably connected inside the arc-shaped limiting groove 33. Several positioning slots 35 are opened on the top left and right sides of the outer surface of the pump body 2. The front and rear sides of the bottom of the outer surface of the water inlet pipe 4 and the water outlet pipe 5 are fixedly connected to the positioning components 36. The positioning components 36 include connecting sliding plates 361. Four connecting sliding plates 361 are fixedly connected to the front and rear sides of the bottom of the outer surface of the water inlet pipe 4 and the water outlet pipe 5 respectively. The bottom of the connecting sliding plate 361 is provided with a square sliding groove 362. The inner surface of the square sliding groove 362 is slidably connected to a square insert 363. The bottom end of the square insert 363 is slidably inserted into the inner surface of the positioning slot 35. The top center of the square insert 363 is threadedly connected to a transmission screw 364. The top end of the transmission screw 364 passes through to the top of the connecting sliding plate 361 and is fixedly connected to a knob 365.

[0030] The overall effect of Embodiment 1 is as follows: the angle adjustment component 3 enables fine-tuning of the angles of the inlet pipe 4 and the outlet pipe 5, which can accurately match the pipeline route, reduce the use of bends, and avoid turbulence caused by pipeline connection. At the same time, the arc-shaped limiting plate 34 slides in the arc-shaped limiting groove 33, ensuring the stability and sealing of the angle adjustment process. Rotating the knob 365 drives the transmission screw 364 to rotate, causing the square insert 363 to move up and down along the square slide groove 362. Through cooperation with the positioning slot 35, the adjusted angle can be controlled and fixed firmly to prevent angle deviation during equipment operation and ensure the smoothness of fluid transportation.

[0031] Example 2: Figure 4 and Figure 5As shown, this utility model provides a technical solution: a filter screen 41 is fixedly connected to the top of the inner surface of the water inlet pipe 4, a spiral degassing plate 42 is fixedly connected to the bottom of the filter screen 41, a turbulence suppression ring 43 is fixedly connected to the bottom of the inner surface of the water inlet pipe 4, a honeycomb rectifier core 51 is fixedly connected to the bottom of the inner surface of the water outlet pipe 5, a conical damping section 53 is fixedly connected to the top of the honeycomb rectifier core 51, a number of axial flow guide ribs 54 are fixedly connected to the inner surface of the conical damping section 53 in an annular array, a number of fan-shaped flow guide holes 44 are opened on the inner side of the turbulence suppression ring 43 in an annular array, and a number of vertically penetrating hexagonal microchannels 52 are opened inside the honeycomb rectifier core 51.

[0032] The overall effect of embodiment 2 is as follows: the filter screen 41 in the inlet pipe 4 can effectively filter impurities in the fluid, preventing impurities from entering the pump body 2 and causing wear on the rotor and generating additional friction and shear force; the spiral degassing plate 42 can separate air bubbles in the fluid, reducing the impact and shear caused by the bursting of air bubbles inside the pump cavity; the fan-shaped guide hole 44 of the turbulence suppression ring 43 can regulate the flow state and reduce the degree of turbulence of the fluid; the honeycomb rectifier core 51 in the outlet pipe 5 forces the fluid to flow in layers through the hexagonal microchannel 52; the conical damping section 53 buffers the pressure fluctuation when the fluid is discharged; and the axial guide rib 54 suppresses the radial disturbance of the fluid, further improving the stability of the fluid discharge.

[0033] The working principle of the entire device is as follows: When the device is started, the drive motor 1 runs, and its output shaft drives the rotor inside the pump body 2 to rotate synchronously in opposite directions, causing the pump chamber volume to change periodically, thereby generating the power to suck in and discharge fluid. The fluid first enters through the inlet pipe 4. Inside the inlet pipe 4, the filter screen 41 at the top filters the fluid and removes impurities. Then the fluid flows through the spiral degassing plate 42. Under the guidance of the spiral degassing plate 42, the bubbles in the fluid gradually rise and separate from the fluid. Next, the pre-treated fluid reaches the turbulence suppression ring 43. Through the fan-shaped guide hole 44 on its inner side, the flow state of the fluid is regulated and the degree of turbulence is reduced, so that it enters the pump chamber of the pump body 2 with a more stable flow state. Inside the pump chamber, the rotation of the rotor enables fluid transport. The fluid then enters the outlet pipe 5. Upon entering the outlet pipe 5, the fluid first passes through the honeycomb rectifier core 51, where it is forcibly stratified by the hexagonal microchannels 52, resulting in a more orderly flow. Next, the fluid enters the conical damping section 53, where the conical structure buffers pressure fluctuations. Simultaneously, the axial flow guide ribs 54 within the conical damping section 53 guide the fluid axially, suppressing radial disturbances and ensuring the fluid is discharged from the outlet pipe 5 in a stable state. Throughout the fluid transport process, if there is a slight deviation in the pipeline routing, the angle adjustment component 3 can be used to adjust the angles of the inlet pipe 4 and the outlet pipe 5. Fine-tuning: Rotate knob 365 to drive transmission screw 364 to rotate, causing square insert 363 to move upward along square slide groove 362 and disengage from positioning slot 35. At this time, arc-shaped slide plate 32 can slide along arc-shaped slide groove 31, driving inlet pipe 4 or outlet pipe 5 to adjust the angle. During the adjustment process, arc-shaped limiting plate 34 slides synchronously in arc-shaped limiting groove 33 to ensure the stability and sealing of the adjustment. After adjusting to the appropriate angle, rotate knob 365 in the opposite direction to insert square insert 363 into the corresponding positioning slot 35 to complete the angle fixation, ensuring smooth pipe connection and reducing the increase of turbulence and shear force caused by pipe connection problems.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
