However, during the use of existing elbows, the elbow parts are often subjected to large fluid impact pressure, which is prone to corrosion damage and leakage failures, affecting the progress of the salt production process. In view of this, the utility model proposes a primary brine and high nitrate water recovery and transportation pipeline to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example:
[0026] like Figure 1-4 As shown, this embodiment proposes a primary brine high-nitrate water recovery and transportation pipeline, including an arc-shaped pipeline A10, wherein an arc-shaped pipeline B20 is arranged inside the arc-shaped pipeline A10;
[0027] The arc pipe A10 and the arc pipe B20 are adapted to each other, and flanges 40 are provided at both ends of the arc pipe A10. A limiting component 30 is provided on the flange 40. The limiting component 30 is connected to the arc pipe A10 to limit the arc pipe B20 in the inner cavity of the arc pipe A10.
[0028] In this embodiment, during use, the arc-shaped pipe B20 is extended into the inner cavity of the arc-shaped pipe A10 to form a double-layer structure, and then the limiting assembly 30 is installed on the flange 40, and the arc-shaped pipe B20 is limited by the limiting assembly 30;
[0029] Through the coordination between the arc pipe A10 and the arc pipe B20 set as above, a double-layer structure can be formed. When transporting liquid in the salt making process, the overall mechanical strength of the elbow can be effectively enhanced and its pressure resistance can be improved. The air layer between the double shells has a heat insulating effect, which can reduce thermal stress and thermal fatigue. At the same time, if the inner pipe leaks, the outer shell can play a secondary containment role to reduce the risk of environmental pollution. The arc pipe A10 and the arc pipe B20 are connected by a limit assembly 30, which can facilitate the subsequent maintenance and replacement of the arc pipe B20, thereby improving the overall practicality.
[0030] Specifically, the inner wall of the arc-shaped pipe A10 is provided with a guide groove 11, and the outer wall of the arc-shaped pipe B20 is provided with a guide strip 21;
[0031] The guide strip 21 is matched with the guide groove 11 .
[0032] In this embodiment, the cooperation between the guide strip 21 and the guide groove 11 can prevent the arc-shaped pipe B20 from rotating when it is installed into the arc-shaped pipe A10, thereby affecting the installation efficiency.
[0033] Specifically, the outer wall of the arc-shaped pipe B20 is in contact with the inner wall of the arc-shaped pipe A10.
[0034] Specifically, the limiting assembly 30 includes a connecting plate 32, and a plurality of connecting holes 31 are formed on the connecting plate 32;
[0035] The connection hole 31 is located to match the flange 40 .
[0036] In this embodiment, by matching the connecting hole 31 with the flange 40, when the flange 40 is later connected to other flanges 40, the connecting plate 32 can be clamped and the connecting plate 32 can be positioned, so that when the two sets of connecting plates 32 are respectively connected to the arc pipe A10, the arc pipe B20 is limited in the inner cavity of the arc pipe A10.
[0037] Specifically, the connecting plate 32 is provided with an extension pipe 33, and the connecting plate 32 is arranged in the middle of the extension pipe 33;
[0038] The extension pipe 33 extends into the inner cavity of the arc-shaped pipe B20.
[0039] In this embodiment, the arc-shaped pipe B20 can be effectively limited by extending the pipe 33 into the arc-shaped pipe B20.
[0040] Specifically, two groups of sealing grooves 311 are formed on the extension pipe 33 , and sealing strips are provided in the sealing grooves 311 .
[0041] In this embodiment, the sealing performance can be improved by providing a sealing strip in the sealing groove 311 .
[0042] Specifically, the sealing groove 311 is symmetrically arranged with the connecting plate 32 .
[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
