[0002] In industries such as chemical, pharmaceutical, and food processing, large amounts of saline wastewater are often generated during production. High-salt wastewater can cause soil organisms and plants to die due to dehydration, leading to the collapse of the soil ecosystem. Therefore, it cannot be discharged directly.

[0029] like Figure 1-3 As shown, this utility model provides a waste salt filtration and collection device, including an evaporator 1, a spiral shaft 7, a drive mechanism 8, and a paddle 9;

[0030] The top of one side of the evaporator 1 is connected to a feed pipe 2, the bottom of the other side of the evaporator 1 is connected to a first discharge pipe 3, the top of the evaporator 1 is connected to a second discharge pipe 4, the second discharge pipe 4 is connected to a condensation mechanism 6, and the bottom of the evaporator 1 is provided with a first heating mechanism 5, which is used to provide the heat required for the evaporation of saline wastewater.

[0031] The saline wastewater is heated and evaporated in the evaporator 1. The saline wastewater is introduced into the evaporator 1 through the feed pipe 2. After the saline wastewater is evaporated and concentrated, the impurities with extremely low water content are discharged from the evaporator 1 through the first discharge pipe 3. The large amount of water vapor generated is discharged from the evaporator 1 through the second discharge pipe 4. The water vapor is condensed and collected through the condensation mechanism 6.

[0032] The spiral shaft 7 is rotatably installed inside the evaporator 1. The spiral shaft 7 has a hollow design. One end of the spiral shaft 7 is connected to a second heating mechanism 10. The second heating mechanism 10 is used to deliver heat transfer oil into the spiral shaft 7 and the blade 9. The heat transfer oil has high thermal conductivity and stability and is suitable as a heating medium, so that the spiral shaft 7 and the blade 9 become heating surfaces. The spiral shaft 7 and the blade 9 heat the salt-containing wastewater in the evaporator 1.

[0033] The drive mechanism 8 is used to drive the spiral shaft 7 to rotate;

[0034] The blades 9 are provided in multiple arrays, which are arranged along the axial direction of the helical shaft 7. The blades 9 are hollow and the cavities of the blades 9 are connected to the cavities of the helical shaft 7.

[0035] The spiral shaft 7 and the blades 9 are provided in two sets, and the two sets of blades 9 are interlaced and arranged. The two spiral shafts 7 rotate in opposite directions. When impurities adhere to the blades 9, the blades 9 can be self-cleaned by the rotation of adjacent blades 9, thereby ensuring that solid impurities are discharged from the evaporator 1 from the first discharge pipe 3.

[0036] The working principle is as follows:

[0037] The saline wastewater is fed into the evaporator 1 through the feed pipe 2. The first heating mechanism 5 at the bottom of the evaporator 1 provides heat to heat and evaporate the saline wastewater. The spiral shaft 7 and the blades 9 are heated by the second heating mechanism 10, which delivers heat-conducting oil to form a heating surface to further heat the saline wastewater. The drive mechanism 8 drives the spiral shaft 7 to rotate, which in turn drives the blades 9 to stir the saline wastewater, ensuring that the material is heated evenly and preventing salt from clumping. The two sets of spiral shafts 7 and blades 9 are interlaced and rotate in opposite directions to enhance the stirring effect and achieve the self-cleaning function of the blades 9 to prevent impurities from adhering. A large amount of water vapor generated during the evaporation process is discharged from the evaporator 1 through the second discharge pipe 4. The water vapor enters the condensation mechanism 6 for condensation. The condensed liquid water is collected to achieve water resource recycling. The impurities with extremely low water content after evaporation are discharged from the evaporator 1 through the first discharge pipe 3 and enter the subsequent processing steps.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
