Description

Technical Field

[0001] The utility model belongs to the technical field of brine precipitation separation, and in particular relates to a brine precipitation separation system. Background Art

[0002] The salt water precipitation separation system is mainly used to separate substances in the solution by using the principle of salting out. Salting out precipitation is to change the ionic strength, take advantage of the different solubility of different proteins under different salt concentration conditions, and add a certain concentration of neutral salt to the solution to make the target substance or impurities precipitate from the solution, thereby achieving the purpose of separation.

[0003] Currently, the precipitation and separation processes of brine are often handled independently, that is, the precipitation operation is performed first, and then the precipitated brine is transferred to another separation device for subsequent separation treatment. This separation method not only increases the complexity of pipeline setup and increases costs, but also during the transfer process, the precipitated crystals are easily damaged or broken, reducing the quality and integrity of the product. In addition, the lack of a pretreatment step for crystallization makes the subsequent crystal drying process time-consuming, affecting the efficiency of the entire production process.

[0004] Therefore, it is very necessary to invent a salt water precipitation separation system. Utility Model Content

[0026] The crystal pretreatment conveyor 2 includes a chassis 21, a heater 22, an inlet 23, a feeding screw 24, a conveying motor 25, an exhaust fan 26 and a discharge pipe 27. The chassis 21 is fixed to the sedimentation separation box 11, the heater 22 is fixedly installed on the chassis 21, and the inlet 23 opened on the chassis 21 is connected to the discharge port 13; the feeding screw 24 is rotatably installed inside the chassis 21, and the lower end of the feeding screw 24 rotates through the chassis 21 and is fixed to the output end of the conveying motor 25 fixedly installed outside it; the exhaust fan 26 is fixedly installed at the upper end and both sides of the chassis 21, and the exhaust fan 26 is located above the discharge pipe 27.

[0027] Embodiment 1:

[0028] Specifically, the sedimentation separation box 11 is a conical structure, and the space inside the sedimentation separation box 11 gradually becomes smaller from top to bottom, which is conducive to the natural sedimentation of solid particles in the brine under the action of gravity, because as the space gradually shrinks, the sedimentation speed of the particles will be accelerated, thereby improving the sedimentation efficiency; the sedimentation separation box 11 is fixedly installed with two driving motors 14 through a motor seat, and the output ends of the driving motors 14 are respectively fixed to the discharge screw 12 and the valve plate 15. Since the bottom space is small, when the sediment needs to be discharged, the concentrated sediment can be effectively pushed out through the rotation of the discharge screw 12 and discharged through the discharge port 13, reducing the difficulty and time of discharge.

[0029] Specifically, the discharge screw 12, the separation filter 16 and the valve plate 15 are arranged in sequence from top to bottom, forming an orderly hierarchical structure, which ensures that the sediment in the brine can be processed according to the predetermined process when passing through the equipment. The separation filter 16 is located below the discharge screw 12. The function of the separation filter 16 is to ensure that only small, pure crystals can be retained. At the same time, the separation filter 16 and the valve plate 15 are both arc-shaped structures, and the two fit tightly together, so that they can form a tight sealing surface in a closed state, effectively preventing the leakage of brine and sediment. When the brine needs to be discharged, the valve plate 15 will perform an arc motion under the control of the drive motor 14, thereby opening the channel between the separation filter 16 and the separation filter 16, so that the brine can be discharged smoothly. The internal space of the chassis 21 allows the valve plate 15 to move in an arc trajectory.

[0030] Specifically, the discharge screw 12 and the feeding screw 24 rotatably installed inside the chassis 21 are both blade feeding shafts, and the discharge screw 12 and the feeding screw 24 are used to transport crystals precipitated in the brine; the feed inlet 23 is opened below the chassis 21.

[0031] Specifically, exhaust holes are provided on the upper end surface and the upper two side surfaces of the chassis 21 , and the exhaust fans 26 are fixedly installed at the exhaust holes. There are three exhaust fans 26 in total, and the three exhaust fans 26 are located above the Z-shaped discharge pipe 27 .

[0032] Embodiment 2:

[0033] Working principle:

[0034] Sedimentation separation principle: Using gravity, solid particles in the brine are naturally settled in the sedimentation separation box 11 of the sedimentation separation integrated device 1. As the space gradually shrinks, the sedimentation speed of the particles will increase, thereby improving the sedimentation efficiency.

[0035] Principle of heating pretreatment: In the crystallization pretreatment conveyor 2, the crystals are subjected to heating pretreatment by the heater 22 to reach the temperature or state required for subsequent treatment.

[0036] Conveying principle: The precipitate or crystal is conveyed from one part of the equipment to another part by the rotation of the discharge screw 12 and the feed screw 24. The discharge screw 12 also has a stirring effect by rotating.

[0037] Sealing and discharge principle: The separation and discharge of salt water and sediment is controlled by the arc movement of the valve plate 15. When the valve plate 15 is tightly fitted with the separation filter 16, sealing is achieved; when the valve plate 15 is opened by arc movement, salt water is allowed to pass.

[0038] Workflow:

[0039] Brine entry: The brine first enters the sedimentation and separation box 11 of the integrated sedimentation and separation device 1 .

[0040] Sedimentation separation: In the sedimentation separation box 11, the solid particles in the brine settle naturally under the action of gravity and remain above the separation filter 16 and around the discharge screw 12.

[0041] Brine discharge: When brine needs to be discharged, the driving motor 14 drives the valve plate 15 to move in an arc shape, opening the channel between the valve plate 15 and the separation filter screen 16, so that the brine can be discharged smoothly and enter the filter tank 4 and the distillation tower 6 through the pumping device 5 and the conveying pipeline assembly 7, and the filter tank 4 filters the solution.

[0042] Sediment discharge: When the brine is completely discharged, the discharge screw 12 is driven to rotate by the drive motor 14 to push out the sediment at the bottom and discharge it through the discharge port 13.

[0043] Crystallization pretreatment: The crystals in the brine enter the housing 21 of the crystallization pretreatment conveyor 2 through the inlet 23. In the housing 21, the crystals are heated and pretreated by the heater 22.

[0044] Crystal conveying: During the pretreatment process, the crystals are conveyed to the discharge pipe 27 under the rotation of the feed screw 24, and finally conveyed to the drying equipment.

[0045] Exhaust: During the heating and conveying process, the gas in the chassis 21 will be exhausted through the exhaust fan 26 to ensure that the internal environment of the chassis 21 is good.

[0046] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
