Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wastewater evaporation equipment, specifically relating to a wastewater evaporation device. Background Technology
[0002] Wastewater evaporators are designed for chemical organic wastewater with high salinity and concentration, based on the principle of evaporation, concentration, and crystallization. They employ multi-effect vacuum evaporation to concentrate and crystallize the organic wastewater. After separating the salt from the concentrate, it is recovered through a salt collector. The concentrate is then dried and recovered or incinerated. The condensate after evaporation is generally treated through subsequent biochemical processes, achieving the required wastewater discharge standards.
[0003] Existing wastewater evaporators have low evaporation efficiency, and after evaporation, salts and other substances in the concentrated liquid adhere to the inner wall of the evaporator. If not cleaned for a long time, residue will accumulate on the inner wall of the evaporator, making cleaning inconvenient. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art, thereby providing a wastewater evaporation device with high evaporation efficiency and no residue adhering to the inner wall of the tank.
[0005] The purpose of this utility model is achieved as follows: A wastewater evaporation device includes a tank body, a vacuum mechanism connected to the top of the tank body, heaters respectively provided on the left and right end faces of the tank body, a disturbance plate provided in the tank body, the disturbance plate being fixed on a rotating shaft, the rotating shaft being rotatably connected to the left and right end faces of the tank body, the rotating shaft being connected to the output shaft of a motor, the tank head being connected to a cooling pipe through a steam pipe, the other end of the cooling pipe being provided with an exhaust port, a liquid inlet being provided on the top face of the tank body, and a residue scraping mechanism connected to the disturbance plate.
[0006] Furthermore, a filter screen is installed at the liquid inlet to remove impurities from the wastewater entering the tank.
[0007] Furthermore, the cooling pipe includes a pipe body, a coolant channel is provided at the center of the pipe body, a steam channel is provided between the coolant channel and the inner wall of the cooling pipe, coolant is provided in the coolant channel, and the steam automatically cools down after passing through the steam channel of the cooling pipe and is then discharged from the outlet of the steam channel.
[0008] Furthermore, the coolant channel is spirally arranged at the center of the pipe body. The spiral arrangement of the coolant can prolong its residence time inside the pipe body, so that the heat can be more evenly distributed throughout the pipe body.
[0009] Furthermore, the steam channel is spirally arranged between the inner wall of the cooling pipe and the coolant pipe, and the steam spirals around the coolant channel through the pipe body, which can prolong its residence time in the pipe body, thereby achieving a better cooling effect.
[0010] Furthermore, the residue scraping mechanism includes a scraper connected to the outside of the disturbance plate. The outer end of the scraper abuts against the inner wall of the tank. The scraper can scrape off the residue on the side wall of the tank, preventing the residue from adhering and accumulating on the inner wall of the tank for a long time.
[0011] Furthermore, the scraper and the disturbance plate are connected by a telescopic sliding connection through a guide mechanism, and an elastic buffer mechanism is provided between the scraper and the disturbance plate. The elastic buffer mechanism can press the scraper tightly against the inner wall of the tank, and can reduce the wear of the scraper on the inner wall of the tank when the inner wall of the tank is not regular in shape.
[0012] Furthermore, the guiding mechanism includes a guide sleeve fixed on the inner side of the scraper, and a sliding rod is slidably disposed inside the guide sleeve. The other end of the sliding rod is fixed to the disturbance plate.

[0013] Furthermore, the elastic buffer mechanism includes a buffer spring disposed between the scraper and the disturbance plate.
[0014] Furthermore, a level gauge is installed on the inner wall of the tank, which can monitor the amount of wastewater in the tank in real time. When the wastewater in the tank is lower than a certain level, wastewater is added to the tank in a timely manner, and when the wastewater in the tank is higher than a certain level, the injection of wastewater into the tank is stopped.
[0015] The beneficial effects of this utility model are:
[0016] 1. This utility model has a vacuuming mechanism connected to the body of the evaporator to improve the vacuum level of the evaporator, thereby effectively improving the evaporation efficiency of wastewater in the evaporator.
[0017] 2. This utility model has a disturbance plate installed inside the evaporator to stir the wastewater inside the tank, so that the heating device can heat the wastewater in the tank quickly and evenly, thereby improving the evaporation efficiency of the wastewater.
[0018] 3. This utility model has a residue scraping mechanism connected to the disturbance plate. During the process of the disturbance plate stirring the wastewater, the residue scraping mechanism can scrape off the residue on the side wall of the tank in a timely manner to prevent the residue from sticking and accumulating on the inner wall of the tank for a long time.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a wastewater evaporation device includes a tank 1, a vacuum mechanism 2 connected to the top of the tank 1, heaters 3 respectively installed on the left and right end faces inside the tank 1, a disturbance plate 4 installed inside the tank 1, the disturbance plate 4 fixed on a rotating shaft 5, the rotating shaft 5 being rotatably connected to the left and right end faces of the tank 1, the rotating shaft 5 being connected to the output shaft of a motor 6, the head of the tank 1 being connected to a cooling pipe 9 via a steam pipe 7, the other end of the cooling pipe 9 being provided with an exhaust port 8, a liquid inlet 10 being provided on the top face of the tank 1, and a residue scraping mechanism connected to the disturbance plate 4.
[0031] During the evaporation process, the inlet 10 is sealed by a control valve, and then the vacuum mechanism 2 is activated to extract air from the tank 1, increasing the vacuum level inside the tank 1 and thus improving the evaporation efficiency of the wastewater in the evaporator. Then, the heater 3 and the motor 6 are activated. The motor 6 drives the agitator 4 to rotate via the shaft 5 to stir the wastewater in the tank 1, allowing the heater 3 to heat the wastewater in the tank 1 quickly and evenly, thereby improving the evaporation efficiency. As the agitator 4 rotates with the shaft 5, the residue scraping mechanism connected to the agitator 4 cleans the inner wall of the tank 1, preventing residue from accumulating on the inner wall of the tank 1 for a long time. The steam generated inside the tank 1 enters the cooling pipe 9 through the steam pipe 7, and the cooled liquid / gas is discharged through the exhaust port 8 on the cooling pipe 9.
[0032] In one embodiment of this utility model, such as Figure 1 As shown, a filter screen 11 is provided at the liquid inlet 10 to remove impurities from the wastewater entering the tank 1.
[0033] In one embodiment of this utility model, such as Figure 1 As shown, the cooling pipe 9 includes a pipe body 12, and a coolant channel 13 is provided at the center of the inside of the pipe body 12. A steam channel 14 is provided between the coolant channel 13 and the inner wall of the cooling pipe 9. Coolant is provided in the coolant channel 13. The steam automatically cools down after passing through the steam channel 14 of the cooling pipe 9, and then is discharged from the outlet of the steam channel 14.
[0034] In one embodiment of this utility model, such as Figure 1 As shown, the coolant channel 13 is spirally arranged at the center of the tube body 12. The spiral arrangement of the coolant can prolong its residence time inside the tube body 12, so that the heat can be more evenly distributed throughout the tube body 12.
[0035] In one embodiment of this utility model, such as Figure 1 As shown, the steam channel 14 is spirally arranged between the inner wall of the cooling pipe 9 and the coolant pipe. The steam spirals around the coolant channel 13 and passes through the pipe body 12, which can prolong its residence time in the pipe body 12, thereby achieving a better cooling effect.
[0036] In one embodiment of this utility model, such as Figure 1-3 As shown, the residue scraping mechanism includes a scraper 15 connected to the outside of the disturbance plate 4. The outer end of the scraper 15 abuts against the inner wall of the tank body 1. The scraper 15 can scrape off the residue on the side wall of the tank body 1 to prevent the residue from sticking and accumulating on the inner wall of the tank body 1 for a long time.
[0037] In one embodiment of this utility model, such as Figure 1-3 As shown, the scraper 15 and the disturbance plate 4 are telescopically slidably connected by the guide mechanism 16, and an elastic buffer mechanism is provided between the scraper 15 and the disturbance plate 4. The elastic buffer mechanism can press the scraper 15 against the inner wall of the tank 1, and when the inner wall of the tank 1 is not regular in shape, it can reduce the wear of the scraper 15 on the inner wall of the tank 1.
[0038] In one embodiment of this utility model, such as Figure 3As shown, the guiding mechanism 16 includes a guide sleeve 19 fixed on the inner side of the scraper 15. A sliding sleeve rod 20 is slidably disposed inside the guide sleeve 19. The other end of the sliding sleeve rod 20 is fixed on the disturbance plate 4. The sliding connection between the sliding sleeve and the sliding sleeve rod 20 can provide guidance for the movement direction of the scraper 15 relative to the disturbance plate 4, preventing the scraper 15 from deviating relative to the disturbance plate 4, thereby affecting the cleaning effect of the scraper 15 on the inner wall of the tank 1.
[0039] In one embodiment of this utility model, such as Figure 1-3 As shown, the elastic buffer mechanism includes a buffer spring 17 disposed between the scraper 15 and the disturbance plate 4.
[0040] In one embodiment of this utility model, such as Figure 1 As shown, a level gauge 18 is installed on the inner wall of the tank 1. The level gauge 18 can monitor the amount of wastewater in the tank 1 in real time. When the wastewater in the tank 1 is lower than a certain liquid level, wastewater is added to the tank 1 in time. When the wastewater in the tank 1 is higher than a certain liquid level, the injection of wastewater into the tank 1 is stopped.
[0041] In use, an automatic liquid injection mechanism can be connected to the liquid inlet 10 of the tank 1. The automatic liquid injection mechanism is connected to the controller, and the controller is connected to the liquid level gauge 18. Through this mechanism, the amount of wastewater in the tank 1 can be automatically controlled.
[0042] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
