[0002] In the production process of primary brine, the brine temperature needs to be raised to 42°C to speed up the reaction of the two added alkalis with the calcium and magnesium ions in the brine. In the existing process of raising the brine temperature, a plate heat exchanger is used for preheating treatment.

[0003] However, during the use of existing plate heat exchangers, especially under the long-term corrosion of the salt production environment, the fixing studs used to position the two sets of fixed clamping plates are prone to corrosion. When disassembly is required, the fixing nuts on the fixing studs are inconvenient to remove, which affects the efficiency of the two sets of fixed clamping plate pins. In view of this, the utility model proposes a high-efficiency plate heat exchanger for a primary brine preheating system to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] Example:

[0028] like Figure 1-5 As shown, this embodiment proposes a high-efficiency plate heat exchanger for a primary brine preheating system, comprising two groups of fixed pressing plates 10, and multiple groups of plates 30 are arranged between the two groups of fixed pressing plates 10;

[0029] The two groups of fixed pressing plates 10 are each provided with a plurality of pressing grooves 12, and a pressing stud 40 is arranged between the two groups of pressing grooves 12 whose positions match those of the two groups of fixed pressing plates 10. A pressing nut 50 is threadedly sleeved on the pressing stud 40, and a movable groove 13 is arranged on the fixed pressing plate 10, and the position of the movable groove 13 matches that of the pressing groove 12. A clamping frame 20 is clamped in the movable groove 13, and the clamping frame 20 is adapted to the movable groove 13. The clamping frame 20 is arranged in the movable groove 13, and the plurality of pressing studs 40 are respectively wrapped in the corresponding pressing grooves 12.

[0030] In this embodiment, during the assembly process, the clamping studs 40 are pressed into the clamping grooves 12 of matching positions until the multiple groups of clamping studs 40 are placed, and then the corresponding clamping nuts 50 are installed on the multiple groups of clamping studs 40 respectively, and at the same time, the clamping frame 20 is pressed into the movable groove 13, and the multiple groups of clamping grooves 12 are wrapped by the clamping frame 20 to prevent the clamping studs 40 from being separated from the clamping grooves 12. In the later stage, when the clamping studs 40 are corroded in the salt-making environment and cannot be disassembled, the clamping frame 20 is separated from the movable groove 13 to release the restriction on the clamping grooves 12, thereby releasing the wrapping of the clamping studs 40, and then the clamping studs 40 can be removed from the clamping grooves 12;

[0031] Through the cooperation between the above-mentioned clamping frame 20 and the movable groove 13, when the clamping stud 40 is installed, the clamping stud 40 can be pressed into the movable groove 13, which is convenient for the installation of the clamping stud 40. At the same time, after the installation is completed, the clamping frame 20 is clamped into the movable groove 13 to seal the clamping groove 12, which can prevent the clamping stud 40 from detaching. When used for a long time in a salt-making environment, the surface of the clamping stud 40 is corroded and the clamping nut 50 is inconvenient to rotate, the clamping frame 20 can be disassembled to make the clamping stud 40 detach from the clamping groove 12, thereby greatly improving the overall practicality.

[0032] Specifically, an upper guide rail 60 and a lower guide rail 80 are respectively disposed between the two groups of fixed pressing plates 10;

[0033] A bracket 70 is disposed between the upper guide rail 60 and the lower guide rail 80 , and a foot 71 is disposed on the bracket 70 .

[0034] In this embodiment, the upper guide rail 60 and the lower guide rail 80 can facilitate the increase or decrease of the number of plates 30 disposed between the two groups of fixed pressing plates 10 .

[0035] Specifically, a plurality of connecting tubes 11 are disposed on one group of the fixed pressing plates 10 , and another group of the fixed pressing plates 10 is slidably disposed between the upper guide rail 60 and the lower guide rail 80 .

[0036] In this embodiment, the connecting pipe 11 is used to connect with an external pipeline.

[0037] Specifically, the fixed pressing plate 10 is provided with a plurality of positioning holes A14, and the clamping frame 20 is provided with a plurality of positioning holes B21;

[0038] The positions and sizes of the positioning holes A14 and B21 match each other, and a positioning rod 90 is disposed between the positioning holes A14 and B21.

[0039] In this embodiment, the positioning rod 90 is extended into the matching positioning hole A14 and positioning hole B21 , so that the clamping frame 20 can be positioned conveniently to prevent the clamping frame 20 from being separated from the movable groove 13 .

[0040] Specifically, a positioning plate 92 is provided on the positioning rod 90 , and the diameter of the positioning plate 92 is larger than the diameter of the positioning hole B21 .

[0041] In this embodiment, the positioning plate 92 can prevent the positioning rod 90 from completely extending into the positioning hole A14 and the positioning hole B21.

[0042] Specifically, a pulling half ring 91 is provided on the positioning plate 92 , and the pulling half ring 91 is fixedly connected to the positioning plate 92 .

[0043] In this embodiment, the pulling half ring 91 can be provided to facilitate pulling the positioning rod 90 out of the positioning hole A14 and the positioning hole B21.

[0044] Specifically, the positioning rod 90 is interference fit with the positioning hole A14 and the positioning hole B21.

[0045] Specifically, the positioning rod 90 is provided with a movable hole 95 , and the positioning rod 90 is also provided with a plurality of deformation grooves 93 , the plurality of deformation grooves 93 match the positions of the movable hole 95 , and the plurality of deformation grooves 93 divide the positioning rod 90 into a plurality of deformation plates 94 .

[0046] In this case, the positioning rod 90 is made of elastic material, so that the deformation plate 94 has elasticity.

[0047] In this embodiment, when the positioning rod 90 extends into the positioning hole A14 and the positioning hole B21, due to the interference fit between the positioning rod 90 and the positioning hole A14 and the positioning hole B21, the multiple sets of deformation plates 94 shrink and deform, and under the action of elasticity, the deformation plates 94 fit tightly in the positioning hole A14, thereby completing the limiting process of the clamping frame 20, which can effectively facilitate the installation and disassembly processes and improve the overall practicality.

[0048] 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.
