Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

First embodiment

As shown in fig. 1 and 2, the present embodiment provides a pipeline static mixer, which includes a pipeline 100, wherein first connecting flanges 120 are respectively disposed at two ends of the pipeline 100, and a chemical feeding port 110 penetrating the interior of the pipeline 100 is disposed on an outer wall of the pipeline 100, preferably, the first connecting flanges 120 are integrally formed with the pipeline 100, and the chemical feeding port 110 is welded on the pipeline 100. As shown in fig. 3, a plurality of first mixing units 200 and second mixing units 300 are provided inside the pipe 100 coaxially with the pipe 100, and one second mixing unit 300 is provided between every two first mixing units 200, and preferably, the first mixing units 200 are welded to the pipe 100, and the second mixing units 300 are welded to the pipe 100. Specifically, as shown in fig. 4 and 5, the first mixing unit 200 includes a plurality of cone-shaped tubes 210 coaxially installed and uniformly distributed (that is, the tubes 210 are in an open trumpet shape, and the diameter of one end of the tubes 210 is greater than that of the other end), so that the water flows in the pipe 100, when the water flows into the first mixing unit 200, a series of vortexes are generated due to the action of the layered wall of the tubes 210, and when the water reaches a certain flow velocity in the first mixing unit 200, the vortexes are separated from the layered wall of the tubes 210 and enter the core of the turbulent flow, and the flow velocity of the vortexes is attenuated, so that uniform isotropic turbulence is formed in the first mixing unit 200. When the water flows through the first mixing unit 200, a vortex group having a size corresponding to that of the tube 210 is generated, that is, the water flows through each tube in the first mixing unit 200, so that a vortex having a size corresponding to that of the tube is formed, and when the vortices are gathered together, the vortex group is formed. For example, when the water flows through the pipe body a in the first mixing unit 200, a vortex a corresponding to the size of the pipe body a is formed, when the water flows through the pipe body b, a vortex b corresponding to the size of the pipe body b is formed, and so on, a vortex c, a vortex d, and so on are formed, and when the vortices a, the vortex b, the vortex c, and so on are gathered together, a vortex group is formed. The respective tubes 210 are connected together by a strip 220, and preferably, the strip 220 is fixed to the respective tubes 210 by welding, and then, the first mixing unit 200 is welded to the inner wall of the pipe 100 by the strip 220. As shown in fig. 6 and 7, the second mixing unit 300 is a spoiler, and a conical protrusion 310 is formed at the center of the second mixing unit 300, and a plurality of through holes 311 are formed at the protrusion 310 of the second mixing unit 300. The second mixing unit 300 is set in a middle convex conical shape, so that the second mixing unit 300 has the effect of uniform isotropic turbulence, and the water flow after passing through the second mixing unit 300 has a certain acceleration due to the pressure difference of the water flow at two sides of the second mixing unit 300, that is, before the water flow does not pass through the second mixing unit 300, the pressure of the water flow is relatively high, because the second mixing unit 300 has a certain blocking effect on the water flow, and after the water flow passes through the second mixing unit 300, the flow rate of the water flow is accelerated.

In addition, in the present embodiment, the vertical distance between two adjacent tube bodies 210 is one tenth to one fourteen times the diameter of the pipeline 100, that is, the tube body in the first mixing unit 200 has 5-7 cone-shaped tube bodies 210 coaxially arranged. Thus, the water flow is convenient to cut, and more vortexes are generated by the water flow.

Second embodiment

In this embodiment, only the connection manner of the first mixing unit and the second mixing unit is improved, and other joints have the same structure as that of the first embodiment, and are not described herein again.

In the present embodiment, as shown in fig. 8 and 9, the first mixing unit 200 and the second mixing unit 300 are connected by brackets 420, and the brackets 420 are welded to the outer sides of the first mixing unit 200 and the second mixing unit 300, respectively. Specifically, through holes (not shown) are respectively formed in the slats of the first mixing unit 200, through holes (not shown) are formed in the flat plate portion of the second mixing unit 300, and the bracket 420 connects the first mixing unit 200 and the second mixing unit 300 together through the through holes in the slats 220 and the through holes in the second mixing unit 300, so that after the bracket 420 penetrates through the first mixing unit 200 and the second mixing unit 300 together, the first mixing unit 200 and the second mixing unit 300 are respectively welded to the bracket 420. The second connecting flanges 410 are welded to both ends of the bracket 420, and the first connecting flange 120 is connected to the second connecting flanges 410 by bolts. In the present embodiment, the first mixing unit 200 and the second mixing unit 300 are first welded to the bracket 420, the welded assembly is then placed into the pipeline 100, the second connecting flanges 410 are then welded to the two ends of the bracket, and finally the first connecting flange 120 and the second connecting flange 410 are connected by bolts, and the assembly is completed. In this way, when the first mixing unit 200 and the second mixing unit 300 need to be replaced, the second connecting flange 410 at one end needs to be removed, and the assembly needs to be removed and replaced.
