Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to solar energy evaporation equipment for wastewater treatment. Background Art

[0002] With the rapid development of industrialization and urbanization, wastewater treatment issues have become increasingly prominent and have become an important factor affecting environmental quality and sustainable development. Although traditional wastewater treatment methods, such as physical treatment, chemical treatment, and biological treatment, can remove pollutants in wastewater to a certain extent, they often have problems such as high energy consumption, long treatment cycle, and secondary pollution. Therefore, it is particularly important to develop an efficient, environmentally friendly, and energy-saving wastewater treatment method.

[0003] In recent years, solar energy, as a clean and renewable energy source, has gradually attracted attention in the field of wastewater treatment. Solar evaporation technology uses the heat of solar energy to heat wastewater and evaporate the water in it, thereby removing pollutants and purifying water quality. This technology is not only energy-saving and environmentally friendly, but also simple to operate and has low maintenance costs, and has broad application prospects.

[0004] When some existing solar wastewater treatment devices are in use, minerals in the wastewater are easily scaled and adsorbed on the inner wall of the container when the wastewater evaporates. Since there is no cleaning mechanism inside the container, the inner wall of the container cannot be cleaned.

[0005] For example, a new type of solar electroplating wastewater treatment device is disclosed with announcement number CN215327042U. When in use, the solar electroplating wastewater treatment device of this patent absorbs heat through the solar heat-absorbing plate and converts it into electrical energy, which is transferred to the solar heater, and heats the water in the medium container in the solar heater. The hot water is transported to the water bath heater through the hot water delivery pipe. The water bath heating heats and evaporates the high-concentration electroplating wastewater adsorbed from the sewage container by the evaporation layer, that is, the new water-absorbing material, and the heavy metal substances in the high-concentration electroplating wastewater crystallize on the adhesion layer, that is, the pearl cotton, and new sewage is continuously injected into the sewage container through the sewage delivery pipe.

[0006] Since there is no special cleaning mechanism inside the sewage container of the patented solar electroplating wastewater treatment device, after long-term use, the minerals and other impurities contained in the electroplating wastewater will form scale on the inner wall of the container. These scales not only occupy the effective volume of the container and reduce the efficiency of wastewater treatment, but may also have an adverse effect on the treatment process, such as reducing heat transfer efficiency and affecting evaporation rate.

[0007] Therefore, it is necessary to invent a solar evaporation device for wastewater treatment to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a solar evaporation device for wastewater treatment to solve the problems in the above technology.

[0009] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solar evaporation device for wastewater treatment, comprising an evaporation pool, a heating inner tank being fixedly connected to the inside of the evaporation pool, a cleaning mechanism being arranged inside the evaporation pool, the cleaning mechanism comprising a scraper plate, the bottom of the scraper plate being in contact with the inner wall of the heating inner tank, a ball screw being transmission-connected to the middle part of the scraper plate, the two ends of the ball screw being rotationally connected to the two sides of the inner wall of the evaporation pool respectively, the two ends of the scraper plate being slidably connected to a limiting slide bar, the two ends of the limiting slide bar being fixedly connected to the two sides of the inner wall of the evaporation pool respectively, a forward and reverse motor being arranged on the outside of the evaporation pool, one end of the ball screw extending to the outside of the evaporation pool, the end of the ball screw extending to the outside of the evaporation pool being transmission-connected to the output shaft of the forward and reverse motor through gears and belts.

[0013] Preferably, a gap is left between the heating liner and the inner wall of the evaporation pool, and the gap is filled with a heat-insulating layer.

[0014] The gap between the heating tank and the inner wall of the evaporation pool is filled with an insulation layer, which effectively reduces heat loss, improves the utilization efficiency of thermal energy, and reduces energy consumption.

[0015] Preferably, a curved cover is installed on the top of the evaporation pool, a water injection pipe is fixedly connected to the middle of the top of the curved cover, exhaust pipes are fixedly connected to both sides of the top of the curved cover, and an exhaust fan is installed inside the exhaust pipe.

[0016] The design of the curved cover can collect evaporated water vapor and discharge it through the exhaust pipe. The addition of the exhaust fan accelerates the exhaust process and improves the evaporation efficiency. The water injection pipe facilitates the addition of wastewater to be treated into the evaporation pool.

[0017] Preferably, a control panel is installed on the surface of the evaporation pool, and solar power generation components are installed on both sides of the top of the arc cover, and the solar power generation components are electrically connected to the control panel.

[0020] The electric heating wire, the forward and reverse motor and the exhaust fan are controlled to work through the control panel.

[0021] Preferably, a stirring mechanism is provided inside the evaporation pond, the number of the stirring mechanisms is set to two, and the two stirring mechanisms are symmetrically distributed about the ball screw.

[0022] Through the rotation of the stirring mechanism, the wastewater is stirred evenly and fully in the evaporation tank, which is beneficial to speed up the evaporation rate of the wastewater.

[0023] Preferably, the stirring mechanism consists of a rotating shaft and flap blades, the flap blades are fixedly connected to the surface of the rotating shaft, both ends of the rotating shaft are respectively rotatably connected to the inner walls of the evaporation pool, one end of the rotating shaft extends to the outside of the evaporation pool, and the end of the rotating shaft extending to the outside of the evaporation pool is transmission-connected to a ball screw via gears and belts.

[0024] The stirring mechanism is connected to the ball screw through gears and belts, achieving synchronous work with the cleaning mechanism. This not only simplifies the equipment structure, but also improves the overall work efficiency, making the wastewater treatment process more efficient and smooth.

[0025] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0026] 1. By setting a cleaning mechanism inside the evaporation pool, the equipment can automatically and efficiently remove the scale and dirt on the inner wall of the heating tank, which not only avoids the influence of scale on the heat transfer efficiency, but also reduces the workload and time cost of manual cleaning. This automatic cleaning function not only improves the efficiency of wastewater treatment, but also ensures the continuous and stable operation of the equipment, reducing the failure and maintenance cost caused by scaling;

[0027] 2. Through the rotation of the stirring mechanism, the wastewater is stirred evenly and fully in the evaporation tank, so that the wastewater can contact the heating tank more fully, thereby improving the heating efficiency and evaporation rate of the wastewater.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-4 When using the utility model, firstly, inject a proper amount of wastewater into the evaporation pool 1 through the water injection pipe 10, turn on the control panel 12, start the entire wastewater treatment system, and set the rotation speed of the forward and reverse motor 6, the heating power of the electric heating wire 14, the speed of the exhaust fan and other parameters through the control panel 12 according to the properties and treatment requirements of the wastewater;

[0039] Under sunlight, the solar power generation assembly 13 starts to work, converting solar energy into electrical energy to supply the entire system.
