Abstract
Description
Technical Field
[0001] The present application relates to the field of wastewater treatment equipment, and in particular to a high-salt industrial wastewater treatment device. Background Art
[0002] High-salinity industrial wastewater has become one of the important sources of environmental pollution. This type of wastewater not only contains high concentrations of salt, but may also contain a variety of heavy metals and toxic substances, causing great harm to natural water bodies and ecosystems. Therefore, it is particularly important to treat high-salinity industrial wastewater efficiently and in an environmentally friendly manner.
[0003] Currently, there are various methods for treating high-salinity industrial wastewater, among which membrane treatment and evaporation treatment are the two main technical means. Although membrane treatment can achieve efficient salt removal, its high equipment cost and maintenance cost limit its application in large-scale wastewater treatment. In contrast, evaporation treatment has the advantages of low cost and simple operation, and has therefore been widely used in actual industrial wastewater treatment.
[0004] However, there is a significant problem when treating high-salt industrial wastewater by evaporation: as the water evaporates, the salt in the wastewater gradually precipitates and adheres to the bottom and inner wall of the evaporation device. Once the salt crystals are attached, it is difficult for other salt crystals to attach to the same position, and due to the internal structure of the evaporation device, the attachment area of the salt crystals is relatively limited. This phenomenon leads to a low efficiency of salt precipitation from high-salt wastewater, which not only affects the efficiency of wastewater treatment, but may also cause the wastewater to fail to meet environmental protection standards when discharged due to incomplete treatment. Summary of the invention

The scraper 11 is provided with a plurality of through holes 111 for the crystallization column 3 to pass through. The scraper 11 is used to scrape off the salt crystals attached to the inner wall of the evaporation box 1 during the lifting and lowering process of the mounting plate 2, so as to prevent the salt crystals from affecting the attachment effect of the crystallization column 3.
[0026] Reference Figure 1 and Figure 2 The driving assembly 4 includes a driving motor 41, four lifting components 42 and four transmission parts 43. The four lifting components 42 are respectively located at the four sides of the top of the evaporator box 1, and each lifting component 42 includes a rotating seat 421, a rotating shaft 422, a winding wheel 423 and a hanging rope 424. The rotating seat 421 is fixedly connected to the top of the evaporator box 1, and a avoidance hole for the rotating seat 421 to extend is provided on the mounting plate 2. The rotating shaft 422 is rotatably connected to one end of the rotating seat 421 extending from the mounting plate 2, and its axis is parallel to the side length direction of the mounting plate 2. There are two winding wheels 423, which are respectively located at both ends of the rotating shaft 422 and are coaxially fixedly connected to the rotating shaft 422. One end of the hanging rope 424 is wound and fixed on the winding wheel 423, and the other end is fixedly connected to the mounting plate 2. The driving motor 41 is used to drive the rotating shaft 422 of one of the lifting components 42 to rotate, and the ends of two adjacent lifting components 42 are connected by a transmission part 43. The transmission part 43 includes two bevel gears 431 , which are coaxially fixedly connected to the ends of the rotating shafts 422 of two adjacent lifting components 42 , respectively, and the two bevel gears 431 are meshed with each other.
[0027] Reference Figure 1 and Figure 2The drive motor 41 can be used to drive the mounting plate 2 up and down, thereby driving the crystal column 3 to move up and down in the evaporation box 1. When the mounting plate 2 rises, the crystal column 3 is extracted from the wastewater, and the salt crystals attached thereto are taken out with it; when the mounting plate 2 falls, the crystal column 3 is immersed in the wastewater again, providing an attachment area for new salt crystals. By continuously lifting and lowering, efficient precipitation of salt crystals can be achieved.
[0028] Reference Figure 1 and Figure 3 The processing device also includes a discharge assembly 5, which is used to discharge the salt crystals at the bottom of the evaporation box 1. A discharge port 12 is provided on the side of the bottom of the evaporation box 1, and a sealing plate 13 is detachably connected to the discharge port 12. The discharge assembly 5 includes a guide rod 53, a discharge push plate 54 and a driving unit. The guide rod 53 is fixedly connected to the inner wall of the evaporation box 1, and the discharge push plate 54 is slidably connected to the guide rod 53. The driving unit includes a discharge motor 51 and a screw rod 52, the screw rod 52 penetrates the discharge push plate 54 and is threadedly connected to the discharge push plate 54, and the end of the screw rod 52 is rotatably connected to the inner wall of the evaporation box 1.

Through the drive of the discharge motor 51, the discharge push plate 54 can slide on the guide rod 53, thereby pushing out the salt crystals at the bottom of the evaporation box 1.
[0029] Reference Figure 1 Considering factors such as corrosion resistance, high temperature resistance and cost, the crystal column 3 in the present invention is made of ceramic material. Ceramic material has good chemical stability and thermal stability and is suitable for the treatment environment of high-salt industrial wastewater.
[0030] The implementation principle of a high-salt industrial wastewater treatment device in the embodiment of the present application is as follows: the evaporation box 1 is the core part of the treatment device, and the water in the wastewater is evaporated by heating, and the salt is gradually precipitated. A plurality of crystal columns 3 are evenly distributed along the mounting plate 2 and extend into the evaporation box 1, providing a large amount of attachment area for the precipitation of salt. As evaporation proceeds, the salt gradually accumulates on the crystal column 3 to form crystals. The drive assembly 4 controls the lifting and lowering of the mounting plate 2 through the drive motor 41, the lifting component 42 and the transmission part 43, thereby driving the lifting and lowering of the crystal column 3 in the evaporation box 1. When the mounting plate 2 rises, the crystal column 3 is extracted from the wastewater, and the salt crystals attached thereto are taken out; when the mounting plate 2 descends, the crystal column 3 is re-immersed in the wastewater, and continues to provide an attachment area for the precipitation of salt. Through continuous lifting and lowering movements, efficient precipitation of salt crystals is achieved. The scraper 11 in the evaporation box 1 is used to scrape off the salt crystals attached to the inner wall of the evaporation box 1 during the lifting and lowering of the mounting plate 2. This design effectively prevents the accumulation of salt crystals on the inner wall of the evaporation box 1, ensures the adhesion effect of the crystal column 3, and improves the processing efficiency. The discharge assembly 5 drives the discharge push plate 54 to slide on the guide rod 53 through the discharge motor 51 and the screw rod 52 to push out the salt crystals at the bottom of the evaporation box 1. This design realizes the automatic discharge of salt crystals and improves the automation of the processing device.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
