working temperature: distillation is the main process for preparing salt from brine, and the temperature of brine is slightly different in each section and is about 90-120 ℃. The austenitic stainless steel is likely to suffer stress corrosion cracking in the range of 50 to 300 ℃, and in general, stress corrosion cracking tends to occur more easily at higher temperatures. Stainless steel in contact with brine is just in the sensitive temperature range, so stress corrosion is easily generated

Brine pressure: the brine pressure is about 0.5MPa generally, so that materials of related components such as a pump valve, a pipeline, a distillation still and the like bear a considerable stress effect. It is clear that cracking of a material is due to stress, and in an environment without corrosive media, the stress limit of cracking of a material is higher than that of a corrosive environment.

The working principle is as follows: all the electrical appliances used in this application are commercially available products, and the principle thereof is the prior art well known to those skilled in the art, so that the detailed description thereof is omitted, and when the external transport pipe 1 transports the brine, wherein the chlorine ions contained in the brine corrode the inner wall of the inner transport pipe 10, which may cause cracks on the inner transport pipe 10 and the outer transport pipe 1, resulting in cracks on the inner transport pipe 10 and the outer transport pipe 1, so that the brine transported inside the inner transport pipe 10 leaks from the crack of the inner transport pipe 10, and thus the inner wall of the inner transport pipe 10 is coated with the corrosion prevention coating 12, so as to reduce the corrosion of the brine to the inner wall of the inner transport pipe 10, thereby reducing the occurrence of cracking of the inner transport pipe 10 caused by brine corrosion.

A cooling tank 11 is arranged between the external transport pipe 1 and the internal transport pipe 10, when the internal transport pipe 10 transports brine, a worker starts the electromagnetic valve 38 through a control switch 6, so that cooling water flows into the cooling tank 11 from the electromagnetic valve 38, so as to cool the surface of the internal transport pipe 10 transporting brine, thereby avoiding the temperature of the internal transport pipe 10 from being too high, so that the internal transport pipe 10 expands, the metal fatigue value of the internal transport pipe 10 reaches the maximum value, and the surface of the internal transport pipe 10 cracks, a plurality of groups of buffer springs 27 with buffer structures are arranged between the external transport pipe 1 and a socket ring 7, so as to prevent the overlarge stress applied to the external transport pipe 1 during the process of transporting brine, and the surface of the external transport pipe 1 cracks, a joint plate 29 mutually jointed with the outer surface of the external transport pipe 1 is arranged at the other end of the buffer springs 27, therefore, when stress occurs in the external conveying pipe 1, the gap between the attaching plate 29 and the outer surface of the external conveying pipe 1 is too large, so that the buffer spring 27 cannot effectively receive and reduce the stress conducted in the external conveying pipe 1, and the hidden danger that the external conveying pipe 1 cracks is increased.

Still cup joint the strengthening rib 2 of installing the round on the surface of outside transport pipe 1, from this can be effectual to outside transport pipe 1 consolidate, thereby prevent the condition that outside transport pipe 1 from taking place the fracture, and carry out the strengthening rib 2 of consolidating to outside transport pipe 1 can effectually prevent when taking place the fracture on outside transport pipe 1, the inside brine pressure of transporting of outside transport pipe 1, can lead to the gap expansion of 1 fracture department of outside transport pipe, thereby lead to the problem that outside transport pipe 1 takes place the fracture, thereby the staff's working strength of carrying out the maintenance to outside transport pipe 1 after having increased.

When the second splicing plate 9 is installed on the outer surface of the external transport pipe 1 of the worker, the worker clamps the originally unfolded second splicing plate 9 with the sleeve ring 7 and on the external transport pipe 1 through the hinge, after the worker clamps the second splicing plate 9 on the external transport pipe 1, and the magnetic stone 32 is adsorbed to the bottom end of the second splicing plate 9, so as to fix the folded second splicing plate 9, then the worker inserts the penetrating rod 34 into the two installation blocks 30, and then the worker moves the auxiliary plate 37 to the direction of the installation blocks 30 by rotating the screw rod 35, so as to expand the bending rods 36 on the two sides of the auxiliary plate 37, so as to fix the folded second splicing plate 9, so that the second splicing plate 9 has a better reinforcing effect on the external transport pipe 1.

When the worker reinforces the external transport pipe 1 to prevent the external transport pipe 1 from cracking, the worker needs to sleeve a plurality of second splicing plates 9 on the external transport pipe 1 to achieve a better reinforcing effect on the external transport pipe 1, the fixing effect between the single second splicing plates 9 is single, when the worker needs to splice two or more second splicing plates 9, the worker inserts the insertion block 22 into the insertion groove 23, then the worker rotates the rotary wheel disc 13 to enable the fixing block 21 to move upwards to be clamped into the fixing groove 39, so that the two spliced second splicing plates 9 are fixed in a reverse direction, and meanwhile, when the worker rotates the rotary wheel disc 13, the crawler 14 sleeved on the rotating shaft 33 at the bottom end of the rotary wheel disc 13 drives the rotary screw 15 on the other side of the second splicing plates 9 to rotate, make things convenient for the staff in rotatory rim plate 13 time, come to operate two rotatory screw rods 15 to come to make things convenient for the staff to come to fix the second splice plate 9 that splices together, and drive two rotatory screw rods 15 through track 14 and rotate, this process that has also reduced the staff when making second splice plate 9, thereby come to make staff's work intensity reduce.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
