Description

Technical Field

[0001] The utility model belongs to the field of high-temperature salt recovery in molten salt tanks in the heat treatment industry, and specifically relates to a molten salt tank salt recovery device. Background Art

[0002] In the heat treatment industry, the salt bath heating and quenching process is to use molten salt to heat and quench the workpiece. Salt bath heating is faster and of better quality than ordinary air medium furnace heating; deoxidation and oxidation losses are small; and because the workpiece is heated in a suspended state, heat treatment deformation is small.

[0003] However, in the salt bath heating quenching process, salt recovery and reuse is still a problem. Based on economic efficiency, most companies currently choose to use molten salt tanks for salt recovery and recycling. High-temperature molten salt has stability, low viscosity, high ion migration and diffusion speed, high heat capacity, and the ability to dissolve a variety of different materials. At the same time, high-temperature molten salt is also highly corrosive and volatile, which limits its in-depth research and industrial application. Considering these characteristics, there is a certain risk in the recovery and reuse process of the high-temperature molten salt.

[0004] Therefore, developing a device for recovering salt in a molten salt tank and improving the safety of the salt recovery process in the molten salt tank are technical issues that need to be solved urgently. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figure 1-3 As shown, the utility model discloses a molten salt tank salt recovery device, including a tank body and a guide device. The tank body is composed of at least six trapezoidal tanks 1 arranged in a matrix. In this embodiment, they are assembled and welded to hold salt solution. To ensure the safety of the salt solution recovery process, the welds in the tank body must be fully welded and no leakage is allowed.

[0024] To prevent overflow after full liquid, the circumference of the trough body is welded with an anti-overflow plate 7. In this embodiment, the height of the anti-overflow plate 7 is 80 mm. The upper size of the trapezoidal trough 1 is larger than the bottom size, and each end of the trapezoidal trough 1 is detachably connected with an iron chain, one end of which is placed in the trapezoidal trough and the other end is detachably connected to the end of the trapezoidal trough 1. It can be in the form of a hook or other forms. The iron chain is used to facilitate the removal of the salt block for transportation after the salt solution solidifies.

[0025] Specifically, after the salt solution enters the trapezoidal trough 1, it will solidify into a salt block after a certain period of time. After solidification, the iron chain will also be solidified in the salt block. At this time, the salt block can be taken out with the help of the iron chain through the corresponding conveying mechanism, thereby facilitating the transportation of the salt solution.

[0026] A base 9 is provided below the tank body, and the base is connected to the tank body via an I-beam to facilitate forklift transportation.

[0027] The flow guiding device comprises a feed pipe 2, a hand guard 3 and a bracket 4. In this embodiment, the feed pipe 2 is made of a seamless steel pipe.

[0028] Two diversion holes 6 for diversion are symmetrically provided at the bottom of the feed pipe 2. Of course, the number of diversion holes 6 can also be increased. The purpose of providing the diversion holes 6 here is that when the salt solution is diverted, if the diameter is directly passed into the trapezoidal groove, the pressure may be too high to cause sputtering, so the diversion holes 6 are provided to balance the pressure and prevent sputtering.

[0029] The hand guard 3 is vertically arranged on both sides of the feed pipe 2, and its function is to facilitate the handling of the guide device. The bracket 4 is arranged parallel to the lower side of the hand guard 3, and the guide device is clamped on one of the trapezoidal grooves 1 through the bracket 4. Furthermore, the lower end of the bracket 4 is symmetrically provided with a bayonet 5 for easy fixation, and the distance between the bayonet 5 is equivalent to the width of the trapezoidal groove 1, and the opening of the bayonet 5 matches the upper end of the trapezoidal groove 1. When in use, the bayonet 5 will be clamped on the upper end of the trapezoidal groove 1 to facilitate the positioning of the feed pipe 2. Usually, in order to uniformly feed the material, the guide device will be mounted on the trapezoidal groove located in the middle position on one side through the bracket 4.

[0030] The salt solution is pumped into the feed pipe 2, flows into the upper part of the guide device, and flows out from the two symmetrically opened long holes. When one of the trapezoidal grooves is full, the salt continues to be pumped, and it will flow into the adjacent trapezoidal grooves until there is salt solution in each trapezoidal groove, and then the salt pumping stops.

[0031] The size of the trapezoidal groove in the utility model can be set as needed to facilitate transportation. Similarly, the size of the feed pipe 2 can be adjusted according to the trapezoidal groove and actual needs.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
