[0021] 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.

[0022] The utility model provides Figure 1 —4, a brine concentrating device as shown comprises: a concentrating box 1, a driving motor 5, a main pipeline 8 and a discharge plate 11, a supporting bracket 2 is arranged on the inner wall of the concentrating box 1, and a sealed upper cover 7 is installed inside the supporting bracket 2, a frame 3 is fixed on the upper end of the concentrating box 1, and a motor seat 17 arranged in the middle of the frame 3 is used to fix the driving motor 5, the output shaft of the driving motor 5 is connected to the rotating shaft 4, and the main pipeline 8 is fixed to the lower end of the rotating shaft 4, a discharge plate 11 is installed on the rotating shaft 4 below the main pipeline 8, and the bottom of the rotating shaft 4 is connected to the heating device through a mechanical sealing head 13, the middle of the main pipeline 8 is connected to the upper end of the rotating shaft 4 through a pull rod 14, and a pillar 16 is fixed on the rotating shaft 4 on the side of the main pipeline 8, and a vertical heating riser 10 is fixed above the main pipeline 8 through a supporting frame 15.

[0023] The bottom of the concentration box 1 is a trapezoidal structure, and the main pipeline 8 installed on the rotating shaft 4 is parallel to the bottom of the concentration box 1. At the same time, the upper ends of the six groups of heating risers 10 installed vertically on the main pipeline 8 are at the same height, and each group of heating risers 10 is provided with four groups of round tubes, which effectively and evenly heats the material. The heating device injects hot air into the heating risers 10 and the inside of the round tubes to heat the concentrated material through heat conduction. Due to the uniform distribution of the heating risers and the round tubes, the heat can be quickly and evenly transferred to the material, thereby accelerating the evaporation of water and the concentration of the material. At the same time, the exhaust pipe provided on the side of the concentration box 1 can discharge the generated steam in time to keep the temperature and pressure inside the box stable.

[0024] The main pipeline 8 , the rotating shaft 4 and the heating riser 10 are all hollow steel pipes, and the heating device injects hot air into the interior of the heating riser 10 . At the same time, an exhaust pipe is provided on the side of the concentration box 1 .

[0025] A discharge port 12 for installing a control valve is provided at the bottom of the concentration box 1 , and a funnel structure is provided at the upper end of the discharge port 12 , and a discharge plate 11 is installed inside the discharge port 12 .

[0026] A plurality of scrapers 9 are arranged at the bottom of the main pipe 8, and the bottom of the scrapers 9 is in contact with the bottom plate of the concentration box 1. At the same time, the front end side of the main pipe 8 and the front end side of the support 16 are connected through the pull rod 14; when the scrapers rotate with the main pipe, they can effectively scrape off the residues or accumulations on the bottom plate. During the concentration process of the concentrated brine, a thick salt layer is easily formed on the bottom plate due to the precipitation and crystallization of salt.

[0027] The support bracket 2 arranged inside the concentration box 1 is an L-shaped structure, and sealing oil is injected into the support bracket 2, and the support ring of the upper cover 7 is pressed inside the sealing oil to form a sealing structure; when the support ring is pressed inside the sealing oil, it will form a close contact surface with the sealing oil, further enhancing the sealing performance of the entire concentration box; this design not only improves the sealing effect of the device, but also makes the installation and removal of the upper cover more convenient, which is convenient for the maintenance and maintenance of the equipment

[0028] The support plate 6 disposed on the rotating shaft 4 is a cross structure, and the upper end of the support plate 6 is in contact with the middle of the upper cover 7 .

[0029] First, the concentrated brine is introduced into the concentration box 1 through the inlet. A support bracket 2 is provided on the inner wall of the concentration box 1, and a sealed upper cover 7 is installed inside the support bracket 2 to form a closed concentration environment.

[0030] Next, the driving motor 5 is started, and its output shaft is connected to the rotating shaft 4. The main pipe 8 is fixed to the lower end of the rotating shaft 4, and a blanking plate 11 is installed on the rotating shaft 4 below the main pipe 8. When the driving motor 5 is working, the rotating shaft 4 will drive the main pipe 4 and the blanking plate 11 to rotate together;

[0031] At the same time, the heating device starts to work and injects hot air into the heating riser 10. The hot air is transferred to the heating riser 10 through the main pipe 8, and then heats the concentrated brine in the concentration box 1. Due to the action of the hot air, the moisture in the concentrated brine begins to evaporate to form water vapor. As the shaft 4 rotates, the scraper 9 at the bottom of the main pipe 8 begins to work. The bottom of the scraper fits the bottom plate of the concentration box. As the shaft 4 rotates, the scraper 9 scrapes up the concentrated brine or salt crystals accumulated at the bottom of the box to prevent them from accumulating at the bottom of the box. At the same time, it also promotes the full contact between the concentrated brine and the hot air, thereby improving the evaporation efficiency. The evaporated water vapor is discharged from the device through the exhaust pipe, while the concentrated brine or salt crystals gradually accumulate at the bottom of the box under the action of gravity. Due to the existence of the blanking plate, when accumulated to a certain extent, the concentrated brine or salt crystals will be scraped into the discharge port 12 by the blanking plate 11 and discharged from the device through the control valve.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
