Description

Technical Field

[0001] This utility model relates to the field of starch slurry pumping pipeline devices, specifically a starch slurry pumping pipeline device with an anti-sedimentation structure. Background Technology

[0002] The starch slurry pumping pipeline device is a key piece of equipment specifically designed for the efficient and stable transportation of starch slurry. It integrates advanced fluid dynamics design concepts and precise mechanical manufacturing processes, enabling it to accurately adapt to the unique rheological characteristics of starch slurry. This ensures that problems such as starch sedimentation and blockage are effectively avoided during long-distance and complex pumping processes, guaranteeing the stability of starch slurry quality and the continuity of the transportation process.

[0003] When starch slurry flows in a pipeline, it is prone to sedimentation due to its particle characteristics and uneven flow velocity distribution. The sedimented starch gradually accumulates on the inner wall of the pipeline, and the sediment layer thickens over time. This not only reduces the effective flow area of ​​the pipeline, leading to increased pumping resistance, increased energy consumption, and reduced pumping efficiency, but also the sedimented starch may breed bacteria, affecting the quality of the starch slurry and consequently the quality of subsequent products. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a starch slurry pumping pipeline device with an anti-sedimentation structure to solve the technical problems of starch slurry pumping pipeline devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a starch slurry pumping pipeline device with an anti-sedimentation structure, comprising a pipeline, the pipeline including a pipe body, a transmission rail provided on the inner side of the pipe body, and a rubber rack provided on the inner side of the transmission rail;

[0006] A transmission mechanism is slidably connected to the outer side of the tube body. The transmission mechanism includes a sliding ring. A pulley groove is opened on one side of the inner wall of the sliding ring, and a pulley is arranged in the pulley groove. A servo motor is arranged on one side of the sliding ring, and the output end of the servo motor is fixedly connected to the pulley. The surface of the pulley is toothed, and the pulley meshes with the transmission track. Multiple mounting grooves are opened on the inner side of the sliding ring, and magnetic blocks are arranged in the multiple mounting grooves.

[0007] By adopting the above technical solution, a transmission track and rubber rack are provided on the inner side of the pipe body, and a transmission mechanism including a servo motor is slidably connected on the outer side. The pulley meshes with the track, and the sliding ring has a magnetic block, which provides a power transmission and magnetic attraction basis for preventing sedimentation.

[0008] Furthermore, the inner wall of the tube is slidably connected to an anti-sedimentation mechanism, which includes a magnetic suction ring.

[0009] By adopting the above technical solution, an anti-sedimentation mechanism containing a magnetic ring is slidably connected to the inner wall of the pipe. The magnetic ring can move inside the pipe with the magnetic attraction of the transmission mechanism, disturbing the starch slurry and effectively preventing the starch slurry from settling inside the pipe.

[0010] Furthermore, a fixing groove is provided on the outer side of the magnetic ring, and a ball bearing slip ring is provided inside the fixing groove. A plurality of balls arranged in a circular array at equal intervals are rotatably connected to the outer side of the ball bearing slip ring.

[0011] By adopting the above technical solution, a ball bearing slip ring and a ball bearing are installed in the fixing groove on the outer side of the magnetic ring. The ball bearing is tangent to the inner wall of the tube, which reduces the sliding friction of the magnetic ring, making it move more smoothly and helping to prevent sedimentation.

[0012] Furthermore, the magnetic ring has two arc-shaped chamfers on its inner upper and lower sides, and these arc-shaped chamfers are close to the inner wall of the tube.

[0013] By adopting the above technical solution, the inner side of the magnetic ring is provided with an arc-shaped chamfer and is close to the inner wall of the tube. The arc-shaped chamfer surface contour extends and wraps around the axial end of the ball bearing slip ring, avoiding the accumulation and sedimentation of starch slurry and optimizing the anti-sedimentation effect.

[0014] Furthermore, one end of the tube is provided with an inlet, and the other end of the tube is provided with an outlet.

[0015] By adopting the above technical solution, an inlet is set at one end of the pipe and an outlet is set at the other end, which clarifies the inflow and outflow channels of starch slurry, facilitates the transportation of starch slurry in the pipeline, and provides a basic path for the entire pumping process.

[0016] Furthermore, a gap fit is formed between the outer wall of the magnetic ring and the inner wall of the tube, and the magnetic field domain of the magnetic block covers the movement stroke of the magnetic ring.

[0017] By adopting the above technical solution, the outer wall of the magnetic ring is fitted with the inner wall of the tube, and the magnetic field of the magnetic block covers the movement stroke of the magnetic ring, ensuring that the magnetic ring can move stably with the transmission mechanism and effectively preventing sedimentation.

[0018] Furthermore, the rolling contact surface of the ball is tangent to the inner wall of the tube, and the curved profile of the arc-shaped chamfer extends to wrap around the axial end of the ball slip ring.

[0019] By adopting the above technical solution, the rolling contact surface of the ball is tangent to the inner wall of the tube, and the arc-shaped chamfered curved surface extends to wrap around the axial end of the ball slip ring, reducing friction and sediment accumulation, and improving the operating effect of the anti-sedimentation mechanism.

[0020] Furthermore, the opening of the pulley groove faces the transmission track, and the tooth profile of the transmission track and the tooth structure of the pulley form a directional meshing transmission.

[0021] By adopting the above technical solution, the pulley groove opening faces the transmission track, and the tooth profile of the transmission track and the tooth structure of the pulley engage in directional transmission, realizing stable sliding of the transmission mechanism and providing reliable power for preventing sedimentation.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model features a structure that combines a transmission mechanism with a transmission track. The transmission mechanism includes a sliding ring that is slidably connected to the outside of the pipe body. A pulley groove is provided on one side of the inner wall of the sliding ring, and a pulley is installed in the groove. The surface of the pulley is toothed. A servo motor is mounted on one side of the sliding ring, and its output end is fixed to the pulley. When the servo motor is running, it drives the pulley to rotate. Because the opening of the pulley groove faces the transmission track, and the tooth profile of the transmission track is directionally engaged with the tooth structure of the pulley, the sliding ring can slide stably along the outside of the pipe body. This structure solves the problem that traditional starch slurry pumping pipelines lack an effective power transmission structure, making it difficult to drive the relevant anti-sedimentation components to move accurately and stably on the pipeline.

[0024] 2. This utility model features a structure in which an anti-sedimentation mechanism and a transmission mechanism are magnetically coupled. The anti-sedimentation mechanism includes a magnetic ring that is slidably connected to the inner wall of the pipe. A fixing groove is formed on the outer side of the magnetic ring, and a ball bearing ring is installed in the groove. Multiple balls arranged in a circular array at equal intervals are rotatably connected to the outer side of the ball bearing ring. The rolling contact surface of the balls is tangent to the inner wall of the pipe, which reduces the friction when the magnetic ring moves. Two arc-shaped chamfers are provided on the upper and lower sides of the inner side of the magnetic ring, and the arc-shaped chamfers are close to the inner wall of the pipe. The curved contour of the chamfers extends and wraps around the axial end of the ball bearing ring, optimizing the fit with the inner wall of the pipe. At the same time, a magnetic block is provided in the mounting groove on the inner side of the sliding ring. The outer wall of the magnetic ring is in clearance fit with the inner wall of the pipe, and the magnetic field of the magnetic block covers the movement stroke of the magnetic ring. This allows the transmission mechanism to drive the magnetic ring to move synchronously through magnetic attraction when it moves. This structure solves the problem that starch slurry is prone to sedimentation in the pipeline during pumping, affecting the quality and efficiency of transportation. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1:

[0032] A starch slurry pumping pipeline device with an anti-sedimentation structure, such as Figures 1-4 As shown, it includes a pipe 1, which includes a pipe body 101. A transmission rail 104 is provided on the inner side of the pipe body 101, and a rubber rack is provided on the inner side of the transmission rail 104.

[0033] A transmission mechanism 2 is slidably connected to the outer side of the tube body 101. The transmission mechanism 2 includes a sliding ring 201. A pulley groove 202 is opened on one side of the inner wall of the sliding ring 201. A pulley 204 is installed in the pulley groove 202. A servo motor 203 is installed on one side of the sliding ring 201. The output end of the servo motor 203 is fixedly connected to the pulley 204. The surface of the pulley 204 is toothed. The pulley 204 meshes with the transmission rail 104. Multiple mounting grooves 205 are opened on the inner side of the sliding ring 201. Magnetic blocks 206 are installed in the multiple mounting grooves 205. The transmission rail 104 is installed on the inner side of the tube body 101 and has a rubber rack on the inner side. The transmission mechanism 2 is slidably connected to the outer side. A pulley groove 202 is opened on one side of the inner wall of the sliding ring 201 of the transmission mechanism 2. A toothed pulley 204 is built in. A servo motor 203 drives the pulley 204 to rotate on one side. The opening of the pulley groove 202 faces the transmission rail 104 and meshes with it to achieve stable transmission. Meanwhile, multiple mounting slots 205 inside the sliding ring 201 are equipped with magnetic blocks 206, which provide magnetic attraction conditions for driving the anti-sedimentation mechanism to move in the future. The overall structure provides power transmission and magnetic attraction basis for anti-sedimentation.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4An anti-sedimentation mechanism 3 is slidably connected to the inner wall of the pipe body 101. The anti-sedimentation mechanism 3 includes a magnetic ring 301. When the magnetic block 206 in the transmission mechanism 2 generates a magnetic field, the magnetic ring 301 can slide along the inner wall of the pipe body 101 under the influence of the magnetic field. During the starch slurry pumping process, the movement of the magnetic ring 301 will disturb the starch slurry in the pipe, disrupting the stable sedimentation environment of the starch slurry in the pipe, thereby effectively preventing the starch slurry from settling in the pipe and ensuring the quality of starch slurry delivery.

[0035] See Figure 1 , Figure 4 The magnetic ring 301 has a fixing groove 303 on its outer side. A ball bearing slip ring 304 is installed inside the fixing groove 303, and multiple balls 305 arranged in a circular array at equal intervals are rotatably connected to the outer side of the ball bearing slip ring 304. The rolling contact surface of the balls 305 is tangent to the inner wall of the tube body 101. When the magnetic ring 301 slides against the inner wall of the tube body 101 under the magnetic attraction of the transmission mechanism 2, the balls 305 roll on the inner wall of the tube body 101, greatly reducing the friction between the magnetic ring 301 and the inner wall of the tube body 101, making the movement of the magnetic ring 301 smoother and more conducive to preventing sedimentation of the starch slurry.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The magnetic ring 301 has two arc-shaped chamfers 302 on its inner upper and lower sides, which are close to the inner wall of the tube body 101. The curved contours of the arc-shaped chamfers 302 extend and wrap around the axial end of the ball bearing slip ring 304. During starch slurry pumping, this structure effectively prevents starch slurry from accumulating and settling at the connection between the magnetic ring 301 and the inner wall of the tube body 101, as well as at the axial end of the ball bearing slip ring 304. Because the smooth curved surface of the arc-shaped chamfers 302 allows the starch slurry to flow smoothly without forming sedimentation dead zones, the anti-sedimentation effect of the anti-sedimentation mechanism 3 is optimized.

[0037] See Figure 3 , Figure 4The pipe body 101 has an inlet 102 at one end and an outlet 103 at the other end. This structure clearly defines the flow path of the starch slurry within the pipe. The starch slurry enters the pipe 1 through the inlet 102, undergoes a series of conveying and anti-sedimentation treatments within the pipe body 101, and then flows out through the outlet 103. The placement of the inlet 102 and outlet 103 provides a clear start and end point for the entire starch slurry pumping process, providing a basic path for the stable conveying of the starch slurry within the pipe and ensuring the normal operation of the entire pumping system.

[0038] See Figure 1 , Figure 2 A clearance fit is formed between the outer wall of the magnetic ring 301 and the inner wall of the tube body 101. The magnetic field domain of the magnetic block 206 covers the movement stroke of the magnetic ring 301. This clearance fit ensures that the magnetic ring 301 can slide smoothly on the inner wall of the tube body 101 without causing starch slurry leakage or the magnetic ring 301 to shake due to excessive clearance. At the same time, the magnetic field domain of the magnetic block 206 in the mounting groove 205 inside the sliding ring 201 covers the movement stroke of the magnetic ring 301. This ensures that when the transmission mechanism 2 is working, the magnetic block 206 can always generate sufficient magnetic attraction force on the magnetic ring 301, ensuring that the magnetic ring 301 can move stably with the transmission mechanism 2, thereby effectively preventing sedimentation of the starch slurry.

[0039] See Figure 1 , Figure 4 The rolling contact surface of the ball 305 is tangent to the inner wall of the tube body 101. The curved contour of the arc-shaped chamfer 302 extends and wraps around the axial end of the ball slip ring 304. Since the rolling contact surface of the ball 305 is tangent to the inner wall of the tube body 101, the ball 305 can roll smoothly along the inner wall of the tube body 101 when the magnetic ring 301 slides, effectively reducing the friction between the magnetic ring 301 and the inner wall of the tube body 101. Simultaneously, the curved contour of the arc-shaped chamfer 302 on the inner side of the magnetic ring 301 extends and wraps around the axial end of the ball slip ring 304, preventing starch slurry from accumulating and settling at the axial end of the ball slip ring 304. This structural combination improves the operating effect of the anti-settling mechanism 3 from both reducing friction and preventing sediment accumulation, allowing the magnetic ring 301 to move better within the tube to prevent starch slurry sedimentation.

[0040] See Figure 3 , Figure 4The opening of the pulley groove 202 faces the transmission track 104, and the tooth profile of the transmission track 104 and the tooth structure of the pulley 204 form a directional meshing transmission. When the servo motor 203 drives the pulley 204 to rotate, due to this directional meshing relationship, the pulley 204 will move stably along the transmission track 104, thereby driving the sliding ring 201 to slide stably on the outside of the pipe body 101. The stable sliding of the transmission mechanism 2 is the key power source for realizing the anti-sedimentation function. Only when the transmission mechanism 2 operates stably can the anti-sedimentation mechanism 3 be driven to move stably through magnetic attraction, thereby effectively preventing starch slurry from settling in the pipe.

[0041] The implementation principle of this embodiment is as follows: First, starch slurry is injected from the inlet 102 of pipe 1. The starch slurry flows in the pipe body 101 and is ready to flow out from the outlet 103.

[0042] During the pumping process, the servo motor 203 of the transmission mechanism 2 is started. The output end of the servo motor 203 drives the pulley 204 to rotate. Since the opening direction of the pulley groove 202 on one side of the inner wall of the sliding ring 201 faces the transmission track 104, and the tooth profile of the transmission track 104 and the tooth structure of the pulley 204 form a directional meshing transmission, the sliding ring 201 can slide stably along the outside of the pipe body 101.

[0043] The magnetic block 206 installed in the mounting groove 205 inside the sliding ring 201 has a magnetic field range that covers the movement stroke of the magnetic ring 301 in the anti-sedimentation mechanism 3. When the sliding ring 201 slides, the magnetic ring 301 is driven to slide synchronously on the inner wall of the tube body 101 through magnetic attraction.

[0044] The magnetic ring 301 is provided with a ball bearing ring 304 in the outer fixing groove 303. Multiple balls 305 arranged in a circular array are rotatably connected to its outer side. The rolling contact surface of the balls 305 is tangent to the inner wall of the tube body 101. This makes the balls 305 roll on the inner wall of the tube body 101 during the sliding process of the magnetic ring 301, reducing the friction between the magnetic ring 301 and the inner wall of the tube body 101, and making the magnetic ring 301 slide more smoothly.

[0045] The two arc-shaped chamfers 302 set on the upper and lower sides of the inner side of the magnetic ring 301 are close to the inner wall of the tube body 101, and the curved contour of the arc-shaped chamfers 302 extends and wraps around the axial end of the ball slip ring 304, which further optimizes the fit between the magnetic ring 301 and the inner wall of the tube body 101 and avoids starch slurry from accumulating and settling here.

[0046] By sliding the magnetic ring 301 within the pipe body 101, the starch slurry within the pipe body 101 is disturbed, disrupting the sedimentation conditions of the starch slurry within the pipe, thereby effectively preventing the starch slurry from settling during pumping and ensuring the quality and efficiency of starch slurry delivery.
