Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater evaporator that utilizes waste heat. Background Technology
[0002] Wastewater evaporators that utilize waste heat are a type of highly efficient and energy-saving wastewater treatment equipment. They use the waste heat generated during industrial production as a heat source to achieve the evaporation and concentration of wastewater, thereby achieving the goals of water resource recovery and pollutant reduction.
[0003] Salt that evaporates and precipitates often adheres to the inner wall. If it is not cleaned in time, it is easy for it to clump on the inner wall, making it even more difficult to clean the inner wall. Traditional cleaning methods mostly rely on manual cleaning, which is time-consuming, labor-intensive, and inconvenient to operate. Utility Model Content

[0022] 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.
[0023] Please see Figures 1-4A wastewater evaporator utilizing waste heat includes a housing 1, a housing cover 2, a displacement assembly, and a cleaning assembly. The housing 1 is provided with an evaporation chamber with an upper opening, and the housing cover 2 is also provided on the housing 1. The displacement assembly includes a screw 3, a mounting plate 4, a cover 5, a worm gear 6, a worm 7, and a motor 8. The screw 3 is rotatably arranged on both the front and rear sides inside the evaporation chamber. The cover 5 is also provided on one side of the housing 1. The worm 7 and two sets of worm gears 6 are arranged inside the cover 5. The screw 3 passes through the housing 1 and the cover 5 and is centrally connected to the worm gears 6. The output end of the motor 8 passes through the cover 5 and is connected to the worm 7. The mounting plate 4 is U-shaped, and the two free ends of the mounting plate 4 are threadedly connected to the screw 3.
[0024] The cover 2 closes the chamber 1, and uses the heat transferred from the waste heat of other equipment to evaporate the wastewater inside the chamber 1. During the evaporation process, the motor 8 (preferably a servo motor 8) is started. The output end of the motor 8 drives the worm 7 inside the cover 5 to rotate. Since the worm 7 meshes with two sets of worm wheels 6, the rotation of the worm 7 will drive the worm wheels 6 to rotate synchronously. The screw 3 passes through the chamber 1 and the cover 5 and is connected to the center of the worm wheel 6. The rotation of the worm wheel 6 causes the screw 3 to rotate accordingly. The mounting plate 4 is U-shaped, and its two free ends are threaded to the screw 3. The rotation of the screw 3 will cause the mounting plate 4 to move back and forth in the evaporation chamber along the axial direction of the screw 3. Through this transmission structure of worm wheel 6, worm 7 and screw 3, the displacement control of the mounting plate 4 in the evaporation chamber is realized, providing the power and displacement basis for the cleaning component's operation.
[0025] The mounting plate 4 is also provided with a cleaning assembly for cleaning the evaporation chamber. The cleaning assembly includes a scraper 9 and a bolt 10. The scraper 9 is U-shaped, and the side wall of the scraper 9 is attached to the inner wall of the evaporation chamber. The scraper 9 is also provided with a bolt 10 connected to the mounting plate 4.
[0026] The cleaning assembly on the mounting plate 4 includes a scraper 9 and bolts 10. The scraper 9 is U-shaped, with its sidewalls tightly fitted against the inner wall of the evaporation chamber. When the mounting plate 4 moves within the evaporation chamber driven by the displacement assembly, the scraper 9 moves along with it. During this movement, the sidewalls of the scraper 9 scrape against the inner wall of the evaporation chamber, removing the salt adhering to it. The scraper 9 is connected to the mounting plate 4 via bolts 10. This connection method facilitates disassembly and replacement of the scraper 9 when it wears out, ensuring continuous and efficient cleaning.
[0027] During wastewater evaporation, pollutants in the wastewater gradually concentrate. When it is necessary to discharge the concentrated waste, the first switch valve 13 on the discharge pipe 12 is opened. Since the discharge pipe 12 is connected to the bottom wall of the housing 1, the concentrated waste will be discharged from the housing 1 through the discharge pipe 12 under the action of gravity. By controlling the opening and closing of the first switch valve 13, the discharge time and flow rate can be easily controlled to ensure that the waste is discharged in a timely manner and does not affect the normal operation of the evaporator.
[0028] A large amount of gas is generated during wastewater evaporation, and this gas needs to be discharged in a timely manner to ensure stable internal pressure of the equipment. An exhaust pipe 14 on the cover 2 is used to discharge this gas, and a second switch valve 15 on the exhaust pipe 14 controls the venting process. When the gas pressure inside the chamber 1 increases, the second switch valve 15 is opened, and the gas is discharged through the exhaust pipe 14. By properly controlling the opening degree of the second switch valve 15, the venting speed can be adjusted, maintaining the internal pressure of the equipment within a suitable range and ensuring the smooth progress of the wastewater evaporation process.
[0029] The support legs 11 located at the bottom of the housing 1 provide support and ensure the equipment is placed stably. The handles 16 located around the side of the housing cover 2 facilitate the opening and closing of the housing cover 2 by the operator, making it convenient for inspection, maintenance, cleaning, installation and replacement of components inside the equipment.
