Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-salinity wastewater treatment and recovery device. Background Technology

[0002] High-salinity wastewater refers to wastewater with a total salt content of at least 3.5% (mass concentration). High-salinity wastewater is usually treated by evaporation, concentration and crystallization. During evaporation, concentration and crystallization, unidirectional stirring is commonly used to accelerate the evaporation efficiency.

[0003] In existing technologies, electric heating elements or heating tubes are typically used to heat the wastewater treatment container when treating high-salt wastewater. However, this heating method is prone to causing localized overheating and uneven temperature distribution within the wastewater treatment container, which can affect wastewater crystallization and make it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-salt wastewater treatment and recovery device. Through the inclusion of a holding shell and an electric heating element, the device can uniformly heat the recovery shell, preventing uneven heating that could affect wastewater crystallization. The included functional components can scrape away crystals from the inner wall of the recovery shell, preventing crystals from adhering to the inner wall, facilitating crystal recovery, and making the device easy to use.

The built-in container and electric heating element allow for uniform heating of the recycling container, preventing uneven heating that could affect wastewater crystallization. The functional components also allow for scraping away crystals from the inner wall of the recycling container, preventing crystals from adhering to the inner wall and facilitating crystal recovery. The system is easy to use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4 This utility model provides an embodiment of a high-salinity wastewater treatment and recovery device, comprising a support plate 2, a controller 3 fixedly mounted on the support plate 2, the controller 3 being electrically connected to an electric heating tube, four support legs 1 fixedly connected to the lower part of the support plate 2 in an axially symmetrical arrangement, a recovery shell 9 fixedly connected to the support plate 2, a collection shell 901 connected to the lower part of the recovery shell 9, the collection shell 901 being funnel-shaped, a discharge pipe 903 fixedly connected to the lower part of the collection shell 901, a control valve 902 installed on the discharge pipe 903, a holding shell 4 fixedly connected to the outer side of the recovery shell 9, a water inlet pipe 5 fixedly connected to the holding shell 4, and at least four electric heating tubes fixedly connected inside the holding shell 4 in a circumferentially uniform arrangement, and an inlet pipe 8, a steam discharge pipe 6, and a motor 7 fixedly connected to the upper part of the holding shell 4, the inlet pipe 8 being located outside the motor 7. The steam exhaust pipe 6 is connected to an external condenser. The output end of the motor 7 is equipped with a functional component, which includes a drive shaft 702 fixedly installed at the output end of the motor 7. A control frame 701 is fixedly connected to the drive shaft 702, and a scraping frame 704 is fixedly connected to the control frame 701. The scraping frame 704 is in contact with the inner wall of the recovery shell 9. A mixing plate 703 is fixedly connected to the middle of the drive shaft 702. There are four mixing plates 703, which are evenly arranged in a circle. A spiral pusher blade 705 is fixedly connected to the lower part of the drive shaft 702. When the motor 7 is powered on, it drives the drive shaft 702 to rotate, thereby driving the control frame 701 and the mixing plate 703 to rotate, which in turn drives the scraping frame 704 to rotate. The scraping frame 704 can scrape off the crystals on the inner wall of the recovery shell 9, causing them to accumulate and fall, thus preventing the crystals from adhering to the inner wall of the recovery shell 9. The mixing plate 703 can fully mix the high-salt wastewater inside the recovery shell 9, ensuring that the high-salt wastewater can be fully heated.

[0023] The set container shell 4 and electric heating tube can uniformly heat the recycling shell 9, avoiding uneven heating that would affect the crystallization of wastewater; the set functional components can scrape off the crystals on the inner wall of the recycling shell 9, preventing crystals from adhering to the inner wall, facilitating the recycling of crystals, and making it convenient to use.

[0024] Working principle: During use, high-salt wastewater is added into the recovery shell 9 through the inlet pipe 8. The controller 3 controls the electric heating tube to work, heating the heat-conducting liquid inside the shell 4. The heat-conducting liquid comes into contact with the recovery shell 9, thereby heating the recovery shell 9 and causing the high-salt wastewater inside the recovery shell 9 to evaporate and crystallize. The steam is discharged from the steam outlet pipe 6 and condensed and collected by the external condenser. At the same time, the motor 7 is powered on, driving the drive shaft 702 to rotate, which in turn drives the control frame 701 and the mixing plate 703 to rotate, which in turn drives the scraping frame 704 to rotate. The scraping frame 704 can scrape off the crystals on the inner wall of the recovery shell 9, causing them to gather and fall, preventing the crystals from adhering to the inner wall of the recovery shell 9. The mixing plate 703 can fully mix the high-salt wastewater inside the recovery shell 9, ensuring that the high-salt wastewater is fully heated. At the same time, the drive shaft 702 can drive the spiral pusher blade 705 to rotate, thereby pushing the crystals and allowing them to be discharged from the outlet pipe 903.

[0025] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
