Description

Technical Field

[0001] This utility model relates to the field of wastewater evaporation technology, and in particular to an industrial wastewater evaporation device. Background Technology

[0002] Wastewater refers to water that has been severely polluted during use. Based on the chemical properties of the main pollutants contained in industrial wastewater, it can be classified into inorganic wastewater (mainly containing inorganic pollutants), organic wastewater (mainly containing organic pollutants), mixed wastewater (containing both organic and inorganic substances), heavy metal wastewater, wastewater containing radioactive substances, and cooling water that is only polluted by heat. Wastewater recycling is achieved by evaporating the wastewater, solidifying the concentrated wastewater to separate useful salts, and then incinerating or burying the useless solid waste at high temperatures.

[0003] Wastewater evaporation requires a heat source for heating. Direct contact between the heat source and the wastewater maximizes the heat efficiency. However, wastewater contains many components, some of which solidify and adhere to the outer wall of the heating tube after being heated. This significantly interferes with the heat dissipated from the heating tube, affecting the efficiency of heat conduction and consequently the efficiency of wastewater evaporation. Utility Model Content

[0004] The purpose of this application is to provide an industrial wastewater evaporation device to solve the problem mentioned in the background art that the heat source can maximize the thermal efficiency by directly contacting the wastewater. However, wastewater contains many components, and some of these components are prone to solidification and adhesion to the outer wall of the heating tube after being heated. This causes significant interference with the heat dissipated by the heating tube, affecting the efficiency of heat conduction and thus the efficiency of wastewater evaporation.

[0005] To achieve the above objectives, this application provides the following technical solution: an industrial wastewater evaporation device, comprising a water storage tank, an outlet pipe fixedly connected to the front side of the water storage tank, lifting components installed on both the left and right sides of the water storage tank, a cover plate installed on the two lifting components, the cover plate being located directly above the water storage tank, and a first hydraulic cylinder installed on the upper surface of the cover plate, the two lifting components being used to adjust the distance between the cover plate and the water storage tank, a carrier plate being fixedly installed at the output end of the first hydraulic cylinder, two carrier pipes being fixed on the lower surface of the carrier plate, a carrier plate being fixed at the bottom end of the two carrier pipes after passing through the cover plate, a plurality of protective cylinders arranged linearly from left to right being fixed on the lower surface of the carrier plate, an electric heating rod being installed inside the protective cylinder, a fixing rod being sleeved on the outside of the protective cylinder, scraper rings being fixed on both the front and rear sides of the fixing rod, the scraper rings being fixedly installed inside the water storage tank, and an air-cooling component installed on the outlet pipe, the air-cooling component being used to cool the outlet pipe.

[0006] Furthermore, the cover plate has a through hole through which the carrier tube passes, and a sealing ring is installed inside the through hole.

A fixing plate is fixedly installed on the output end of the second hydraulic cylinder, and the cover plate is fixedly installed on the fixing plate.

[0008] Furthermore, the air-cooled assembly includes a ventilation duct, which is fixedly sleeved on the outside of the outlet pipe, and the outlet pipe passes through the inside of the ventilation duct. A fan is installed inside the ventilation duct.

[0009] Furthermore, the outlet pipe is fixedly sleeved with a plurality of heat dissipation fins arranged in a linear pattern, and the plurality of heat dissipation fins are all located inside the ventilation pipe.

[0010] Furthermore, both ends of the ventilation duct are fixedly connected to corrugated extension pipes, the other end of the corrugated extension pipe is fixed to a side pipe, the bottom of the side pipe is fixed to a support rod, and the bottom end of the support rod is fixed to a counterweight base.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: Reference Figure 1-5 An industrial wastewater evaporation device is shown, comprising a water storage tank 1, with an outlet pipe 2 fixedly connected to the front side of the water storage tank 1. Lifting assemblies are installed on both the left and right sides of the water storage tank 1, and cover plates 3 are installed on the two lifting assemblies. The cover plates 3 are located directly above the water storage tank 1, and a first hydraulic cylinder 4 is installed on the upper surface of the cover plate 3. The two lifting assemblies are used to adjust the distance between the cover plate 3 and the water storage tank 1. A carrier plate 5 is fixedly installed at the output end of the first hydraulic cylinder 4, and two carrier pipes 6 are fixedly installed on the lower surface of the carrier plate 5. The bottom ends of the two carrier pipes 6 pass through the cover plate 3 and are fixedly attached to the carrier pipes. The tray 7 and cover plate 3 have through holes through which the carrier tube 6 passes. A sealing ring is installed inside the through hole to enhance the tightness between the carrier tube 6 and the cover plate 3. Multiple protective cylinders 8 are fixed on the lower surface of the tray 7 in a linear arrangement from left to right. An electric heating rod 9 is installed inside the protective cylinder 8. A fixing rod 10 is sleeved on the outside of the protective cylinder 8. Scraper rings 11 are fixed on the front and rear sides of the fixing rod 10. The scraper rings 11 are fixedly installed inside the water storage tank 1. An air-cooling component is installed on the outlet pipe 2 for cooling the outlet pipe 2.

[0023] The electric heating rod 9 heats the inside of the water storage tank 1, causing the sewage inside the tank 1 to evaporate. Some substances in the sewage precipitate out and adhere to the surface of the protective cylinder 8. The first hydraulic cylinder 4 can be manually controlled to pull the carrier plate 5 back and forth in the longitudinal direction at regular intervals. The carrier plate 5, with the help of the carrier pipe 6 and the carrier plate 7, pulls the protective cylinder 8 to move accordingly. During the up and down movement of the protective cylinder 8, it is cleaned by the scraper ring 11, which forces most of the solids adhering to the surface of the protective cylinder 8 to be scraped off. In this way, the electric heating rod 9 can effectively conduct heat to the sewage and improve the efficiency of sewage evaporation.

[0024] The lifting assembly includes a fixed block 12, which is fixedly installed on the water storage tank 1. A second hydraulic cylinder 13 is installed on the fixed block 12. A fixed plate 14 is fixedly installed on the output end of the second hydraulic cylinder 13. The cover plate 3 is fixedly installed on the fixed plate 14. The height of the cover plate 3 is adjusted by the two second hydraulic cylinders 13 to realize the separate operation of the water storage tank 1 and the cover plate 3. This is not only convenient to operate, but also conducive to filling the water storage tank 1 with water and cleaning the inside of the water storage tank 1.

[0025] The air-cooled component includes a ventilation duct 15, which is fixedly sleeved on the outside of the outlet pipe 2, and the outlet pipe 2 passes through the inside of the ventilation duct 15. A fan 16 is installed inside the ventilation duct 15. Multiple heat dissipation fins 17 arranged linearly are fixedly sleeved on the outside of the outlet pipe 2. All the heat dissipation fins 17 are located inside the ventilation duct 15. Corrugated extension pipes 18 are fixedly connected to both ends of the ventilation duct 15. A side pipe 19 is fixed to the other end of the corrugated extension pipe 18. A support rod 20 is fixed to the bottom of the side pipe 19. A counterweight base 21 is fixed to the bottom end of the support rod 20. The fan 16 guides outside air to enter from the left end of the ventilation duct 15 and exit along the right end of the ventilation duct 15. During this process, the outlet pipe 2 can expand its heat exchange surface with the help of the heat dissipation fins 17, and better exchange heat with the air flowing in the ventilation duct 15. In this way, the evaporated water vapor can be better condensed in the outlet pipe 2.

[0026] Stretching the two corrugated extension tubes 18 can significantly increase the length of the air-cooled components, reducing the impact of the exhaust heat on the intake. The side tube 19, support rod 20, and counterweight base 21 work together to support the corrugated extension tubes 18 while helping to fix their position, thus improving ease of use.

[0027] The hydraulic cylinder is equipped with a power source, and the power source is configured as a standard feature in the field, which technicians can implement based on existing technology.

[0028] Working principle of this utility model:

[0029] In use, place the water storage tank 1 on a horizontal ground, and then move the position of the two counterweight bases 21 so that the two corrugated extension pipes 18 are stretched. In this way, the overall length of the air-cooling component increases, the distance between the air inlet and the air outlet increases, and the interference between the two is reduced. Control the two second hydraulic cylinders 13 to push the cover plate 3 upward so that the cover plate 3 is separated from the water storage tank 1. Sewage is injected into the water storage tank 1 along the upper part of the water storage tank 1. The water level of the sewage in the water storage tank 1 is lower than that of the outlet pipe 2.

[0030] After water filling is completed, the two second hydraulic cylinders 13 are operated to pull the cover plate 3 down, so that the cover plate 3 covers the top of the water storage tank 1. The electric heating rod 9 is connected to the power supply, so that the electric heating rod 9 is powered on and runs. The electric heating rod 9 conducts heat outward through the protective cylinder 8, so that the sewage is heated and evaporated. The evaporated water vapor enters the outlet pipe 2. The fan 16 is started, and the outside air enters along the left side pipe 19, cools the outlet pipe 2 and then discharges along the right side pipe 19. The liquefied water is finally discharged along the outlet pipe 2. During the sewage heating process, some substances in the sewage will precipitate and adhere to the surface of the protective cylinder 8. The first hydraulic cylinder 4 can be manually operated to pull the carrier plate 5 back and forth in the longitudinal direction at regular intervals, so that the carrier plate 5 pulls the protective cylinder 8 with the carrier pipe 6 and the carrier plate 7. During the up and down movement of the protective cylinder 8, it is cleaned by the scraper ring 11, which forces most of the solids adhering to the surface of the protective cylinder 8 to be scraped off. In this way, the heat conduction from the electric heating rod 9 to the sewage can be effectively guaranteed.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
