[0001] The utility model relates to the technical field of pipelines, in particular to a self-mixing pipeline. Background Art

[0002] Currently, the chemical, food and beverage industries have increasingly higher requirements for the uniformity of mixing multi-phase substances. Traditional conveying pipelines do not have the function of pre-mixing or re-mixing during the transportation process, and sedimentation is very likely to occur in the pipeline, affecting the thoroughness of the reaction, reducing the unit product reaction output, and increasing costs. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a self-mixing pipe, which can form a mixing effect on the liquid in the pipe and reduce the precipitation phenomenon in the pipe body.

[0004] The utility model discloses a self-mixing pipe, comprising a pipe body, which is axially penetrated, and guide seats are installed on the inner wall of the pipe body, the guide seats are located at the axial ends of the pipe body, and a stirring rod is connected between the two guide seats. In a free state, the middle part of the stirring rod hangs down, and the lower end of the stirring rod is provided with a protrusion, the bottom surface of the protrusion is an inclined surface, and the bottom surface of the protrusion faces the flow direction after the pipe body flows through. When the pipe body flows through, the fluid impacts the bottom surface of the protrusion, so that the protrusion can move upward.

[0005] Furthermore, the guide seat is provided with a through hole, which passes through the guide seat along the axis of the guide seat, and a plurality of through holes are evenly distributed along the circumference of the guide seat.

[0006] Furthermore, both ends of the stirring rod are connected to the center ends of the two guide seats respectively.

[0007] Furthermore, a sleeve is installed between the two guide seats, the outer peripheral wall of the sleeve is in contact with the inner peripheral wall of the pipe body, and a mounting seat is installed on the inner wall of the sleeve. The mounting seat is located above the raised portion in the middle of the stirring rod. The mounting seat is slidably connected to a slider, which can move up and down. The slider is located above the stirring rod, and the upper end of the slider abuts against a spring, and the upper end of the spring abuts against the sleeve.

[0008] Furthermore, the mounting seat includes a lower seat located at the bottom, the bottom of the lower seat is open, the lower seat is through along the length direction of the stirring rod, and the stirring rod passes through the lower seat.

[0009] Furthermore, a plurality of protrusions are provided along the length direction of the stirring rod.

[0010] Furthermore, when the stirring rod is in a free state, the bottom position of the protrusion is higher than the bottom position of the mounting seat.

[0011] Furthermore, a stopper is installed on the inner wall of the sleeve, and a plurality of the stoppers are evenly distributed along the circumference of the sleeve, and the stoppers are distributed in multiple layers along the axial direction of the sleeve.

[0012] Furthermore, the cross section of the block is triangular, and the side facing the flow direction of the pipeline body is a vertical blocking surface.

[0013] Beneficial effects of the utility model:

[0014] 1. When fluid flows through the pipe body, the fluid impacts the bottom surface of the protrusion, causing the protrusion to move upward and drive the stirring rod to swing upward. Because the pressure of the liquid in the pipe body is unstable and the pressure varies at each cross section, the impact force on each protrusion is inconsistent. As the liquid flows through the pipe body, the stirring rod swings in a serpentine shape to achieve a stirring effect, thereby mixing the liquid in the pipe body and reducing sedimentation within the pipe body.

[0015] 2. By setting a block with a triangular cross-section and a vertical blocking surface facing the flow direction of the pipeline body, when the liquid flowing near the inner wall of the sleeve encounters the block, it is blocked and a backflow trend is formed, thereby increasing the mixing effect.

[0019] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 、 Figure 2 As shown, a self-mixing pipeline includes a pipeline body 1, which is axially through and has an inner diameter of 100mm-300mm. Multiple pipeline bodies 1 are connected to form a conveying system for remixing liquid-liquid or liquid-solid during the conveying process.

[0021] like Figure 1As shown, a guide seat 2 is installed on the inner wall of the pipe body 1. The guide seat 2 is located at both ends of the axial direction of the pipe body 1. The guide seat 2 is a cylindrical structure. The guide seat 2 is inserted into the pipe body 1. The outer circumferential wall of the guide seat 2 is attached to and fixed to the inner circumferential wall of the pipe body 1. Figure 2 The guide seat 2 is provided with a through hole 21, which passes through the guide seat 2 along the axis of the guide seat 2. There are four through holes 21 evenly distributed along the circumference of the guide seat 2, and the through holes 21 are used for circulating liquid.

[0022] like Figure 1 As shown, a stirring rod 24 is connected between the two guide seats 2, with both ends of the stirring rod 24 connected to the center ends of the two guide seats 2. The stirring rod 24 is made of butadiene rubber, with a density of 1.93 g / cm3, which is greater than the density of the mixed liquid. In the free state (no liquid flows through the pipe body 1), the stirring rod 24 has a central portion that droops downward, forming an arc shape. The lower end of the stirring rod 24 is provided with a raised portion 241, the bottom surface of the raised portion 241 being an inclined surface, and the bottom surface of the raised portion 241 faces the flow direction of the pipe body 1 after the flow passes through the pipe body 1. When the flow passes through the pipe body 1, the fluid impacts the bottom surface of the raised portion 241, causing the raised portion 241 to move upward and drive the stirring rod 24 to swing upward. Since the pressure of the liquid is unstable when it circulates in the pipe body 1 and the pressure at each cross section is also different, and there are multiple protrusions 241 along the length direction of the stirring rod 24, the impact force on each protrusion 241 is inconsistent. As the liquid circulates in the pipe body 1, the stirring rod 24 forms a serpentine swing to achieve a stirring effect, thereby forming a mixing effect on the liquid in the pipe body 1 and reducing the precipitation phenomenon in the pipe body 1.

[0023] like Figure 1 As shown, a sleeve 22 is installed between the two guide seats 2. The sleeve 22 is a cylindrical structure. The sleeve 22 is coaxial with the pipeline body 1. The sleeve 22 has two axial ends that are connected. The outer peripheral wall of the sleeve 22 fits with the inner peripheral wall of the pipeline body 1. The two axial ends of the sleeve 22 are fixedly connected to the guide seats 2 on both sides.

[0024] like Figure 1 As shown, a mounting seat 25 is installed on the inner wall of the sleeve 22. The mounting seat 25 is located above the raised portion 241 in the middle of the stirring rod 24. The mounting seat 25 is slidably connected to a slider 27. The slider 27 includes an extension block 271 at the bottom. The extension block 271 is located above the stirring rod 24. The slider 27 can move up and down. The upper end of the slider 27 abuts against a spring 26, and the upper end of the spring 26 abuts against the sleeve 22. Figure 2The sliding mounting seat 25 includes an upper seat 251 and a lower seat 252 located below the upper seat 251. The top of the upper seat 251 is fixed to the inner wall of the sleeve 22, and the bottom of the lower seat 252 is open. The lower seat 252 passes through the stirring rod 24 along the length direction, and the stirring rod 24 passes through the lower seat 252. When the stirring rod 24 is in a free state, the bottom position of the protrusion 241 is higher than the bottom position of the lower seat 252, and the lower seat 252 plays a role in limiting the stirring rod 24 on the periphery. When the protrusion 241 moves upward after being subjected to a large impact, the stirring rod 24 moves up to abut against the bottom of the extension block 271 and pushes the slider 27 to move upward. The spring 26 is compressed. When the impact force on the protrusion 241 is weakened, the protrusion 241 is ejected downward under the action of the spring 26, thereby forming the stirring of the stirring rod 24 near the axis of the pipe body 1, thereby enhancing the mixing effect of the liquid. The swing range of the middle part of the stirring rod 24 is the largest. By setting a slider 27 above this part, when the raised part 241 of the stirring rod 24 moves upward a large distance, it is resisted by the slider 27 and the swing back action is accelerated, thereby increasing the frequency of the back and forth swinging and improving the stirring effect.

[0025] like Figure 1 、 Figure 2 As shown, the inner wall of the sleeve 22 is installed with a stopper 23, and four stoppers 23 are evenly distributed along the circumference of the sleeve 22, and the stoppers 23 are distributed in multiple layers along the axial direction of the sleeve 22. Figure 1 As shown, the cross section of the block 23 is triangular, and the side facing the flow direction of the pipeline body 1 is a vertical blocking surface. When the liquid flowing near the inner wall of the sleeve 22 encounters the block 23, it is blocked and forms a backflow trend, thereby increasing the mixing effect.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
