Description

Technical Field

[0001] This utility model relates to the field of demulsification technology for emulsified wastewater, specifically a demulsification device for emulsified wastewater. Background Technology

[0002] Emulsions are high-performance semi-synthetic products formulated with a chlorine-free compound specifically to address various problems encountered during the processing of aluminum and its alloys. The production and processing of emulsions generates a certain amount of wastewater, which is treated using demulsification equipment. Demulsification is essentially the process of eliminating the stabilizing conditions of an emulsion, causing dispersed droplets to aggregate and separate. In many production processes, it is often necessary to break up stable emulsions, i.e., demulsification.

[0003] However, most existing treatments for emulsified wastewater involve only adding a demulsifier in a single step, without any other related operations. This simplistic approach results in poor demulsification and flocculation effects, impacting subsequent treatment efficiency. Furthermore, this method leaves some oily substances in the treated wastewater, which cannot be addressed in subsequent wastewater treatment processes. Additionally, the low drainage efficiency fails to meet the demands of continuous industrial treatment.

[0004] Therefore, we propose a demulsification device for emulsified wastewater to solve the above problems. Utility Model Content

This simplistic approach results in poor demulsification and flocculation effects, impacting subsequent treatment efficiency. Furthermore, this method leaves some oily substances in the treated wastewater, which cannot be addressed in subsequent wastewater treatment processes, leading to low drainage efficiency and failing to meet the demands of continuous industrial treatment.

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.

[0029] Example

[0030] like Figure 1-6 As shown in the figure, an embodiment of the present invention provides a demulsification device for emulsified wastewater, including a demulsification chamber 1, a base plate 2 fixed to the lower end face of the demulsification chamber 1, and a separation chamber 16 connected to one side of the demulsification chamber 1, and further including:

[0031] The base plate 2 is used to support the entire device, while the separation chamber 16 is connected to one side of the demulsification chamber 1 for separating the wastewater after demulsification. The cover plate 3 is fixed to the upper end face of the demulsification chamber 1 by multiple sets of positioning bolts 5. The upper end face of the cover plate 3 is fixed with a demulsifier chamber 4, which can be used to store demulsifier. A water inlet port 6 is opened on one side of the upper end face of the cover plate 3 and is connected to the demulsification chamber 1. The positioning bolts 5 can quickly disassemble and seal the cover plate 3, which can facilitate the subsequent disassembly of the cover plate 3 for subsequent cleaning of the inner wall of the demulsification chamber 1. At the same time, the water inlet port 6 is connected to the inside of the demulsification chamber 1, and the emulsified wastewater enters the demulsification chamber 1 through the water inlet port 6.

[0032] The drive motor 7 is fixed at the center of the lower end face of the demulsification chamber 1. A mixing mechanism is fixed to the output end of the drive motor 7 for emulsifying and flocculating wastewater. When the drive motor 7 starts, it drives the connecting guide rod 8 and the mixing paddle 9 to rotate synchronously, thus agitating the wastewater. The mixing mechanism includes the connecting guide rod 8, the mixing paddle 9, and permeable holes 10. The connecting guide rod 8 is fixed to the output end of the drive motor 7 and is rotatably engaged in the center of the demulsification chamber 1. The mixing paddle 9 is uniformly fixed to the outer surface of the connecting guide rod 8, and the permeable holes 10 are uniformly opened inside the mixing paddle 9. The mixing paddle 9 and permeable holes 10 reduce the amount of wastewater agitated. The water flow resistance during the stirring process improves the uniformity of mixing wastewater and demulsifier. The upper end face of the connecting guide rod 8 is provided with a limiting groove 11, and the cross-section of the limiting groove 11 is set with a rhomboid structure. The inside of the demulsifier chamber 4 is rotatably connected to the linkage rod 12, and the lower end of the linkage rod 12 is slidably engaged with the inner side of the limiting groove 11. The outer surface of the linkage rod 12 is uniformly fixed with stirring rods 13. When the connecting guide rod 8 rotates, the linkage rod 12 is driven to rotate synchronously through the engagement of the limiting groove 11. The stirring rods 13 are uniformly fixed with stirring rods 13 on the outer surface of the linkage rod 12, which can stir the demulsifier in the demulsifier chamber 4 and prevent the demulsifier from settling.

[0033] A metering valve 14 is fixed on one side of the lower end face of the demulsifier chamber 4, and the other end of the metering valve 14 is connected to the demulsifier chamber 1. By adjusting the metering valve 14, the amount of demulsifier added can be precisely controlled, so as to achieve the ratio of demulsifier to wastewater, avoid the problem of waste of reagent or incomplete demulsification, and improve the demulsification effect.

[0034] A separation mechanism, located inside the separation chamber 16, is used to separate pretreated wastewater. The separation mechanism includes a water guide pipe 15, a filter membrane assembly 18, and a drain port 19. The water guide pipe 15 is connected to one end of the demulsification chamber 1, and the other end of the water guide pipe 15 is connected to the separation chamber 16. Demulsified wastewater enters the separation chamber 16 through the water guide pipe 15. The filter membrane assembly 18 is slidably engaged inside the separation chamber 16. The filter membrane assembly 18 is used to filter flocculated impurities in the wastewater, while its interception function... After separating oil droplets and water molecules, only periodic cleaning of the membrane is required. The drain port 19 is connected to the inside of the separation chamber 16 and is arranged in an inverted trapezoidal structure. The inverted trapezoidal structure of the drain port 19 can increase the drain diameter and improve the discharge efficiency of the separated water. The outer side of the separation chamber 16 is rotatably connected to the sealing door plate 17, and the outer surface of the sealing door plate 17 is sealed to the inner wall of the separation chamber 16. The filter membrane assembly 18 can be quickly removed by opening the sealing door plate 17, which is convenient for cleaning or replacing the filter membrane.

[0035] Before use, first, fix the base plate 2 to the lower end face of the demulsifying chamber 1 by welding or bolting to ensure that the base plate 2 and the demulsifying chamber 1 are firmly connected and to ensure the stability of the device when it is placed. Then, fix one end of the connecting guide rod 8 in the mixing mechanism to the output end of the drive motor 7, and then fix the drive motor 7 to the center of the lower end face of the demulsifying chamber 1. At the same time, ensure that the connecting guide rod 8 is rotated and locked in the center of the demulsifying chamber 1 without jamming during rotation.

[0036] Furthermore, the cover plate 3 is fixed to the upper end face of the demulsifier chamber 1 by multiple sets of positioning bolts 5. The mixing paddle 9 is uniformly welded and fixed on the outer surface of the connecting guide rod 8, and water permeable holes 10 are uniformly opened inside the mixing paddle 9. The linkage rod 12 is rotatably connected to the inside of the demulsifier chamber 4, and its lower end is slidably engaged in the limiting slot 11 on the upper end face of the connecting guide rod 8. The limiting slot 11 has a rhomboid cross-section to ensure that the linkage rod 12 can rotate synchronously with the connecting guide rod 8. The stirring rod 13 is uniformly welded on the outer surface of the linkage rod 12, and the length of the stirring rod 13 is adapted to the inner diameter of the demulsifier chamber 4.

[0037] Furthermore, a metering valve 14 is installed on one side of the lower end face of the demulsifier chamber 4, and the other end of the metering valve 14 is connected to the demulsifier chamber 1 to ensure that the metering valve 14 can be opened and closed smoothly and the flow rate can be accurately adjusted.

[0038] Finally, the filter membrane assembly 18 is slidably snapped onto the inside of the separation chamber 16. The filter membrane assembly 18 is a microfiltration membrane. A drain port 19 is connected to the inside of the separation chamber 16. The drain port 19 has an inverted trapezoidal structure, with its large diameter end facing the inside of the separation chamber 16 and its small diameter end facing outward. Finally, the sealing door plate 17 is rotatably connected to the outside of the separation chamber 16 to ensure that the sealing door plate 17 is sealed to the inner wall of the separation chamber 16 and there is no leakage.

[0039] During use, the emulsified wastewater enters the demulsification chamber 1 through the inlet port 6. The inlet speed can be controlled by a flow meter during the inlet process to ensure that the wastewater has sufficient mixing time in the demulsification chamber 1. The drive motor 7 is then started, which drives the connecting guide rod 8 to rotate. The connecting guide rod 8 simultaneously drives the mixing paddle 9 and the linkage rod 12 to rotate. The mixing paddle 9 stirs the wastewater in the demulsification chamber 1, and the water permeable hole 10 reduces water flow resistance, making the wastewater flow more uniform. The linkage rod 12 drives the stirring rod 13 to rotate, stirring the demulsifier in the demulsifier chamber 4 to prevent the demulsifier from settling.

[0040] Then, adjust the metering valve 14 and, according to the total amount of wastewater and the ratio of demulsifier, inject the demulsifier in the demulsifier chamber 4 into the demulsifier chamber 1 in a metered manner. The demulsifier and wastewater are fully mixed under the stirring of the mixing paddle 9, and an emulsification and flocculation reaction occurs.

[0041] After demulsification and flocculation, the wastewater enters the separation chamber 16 through the water guide pipe 15. The wastewater is filtered by the filter membrane module 18, and the flocculated impurities are intercepted. The clean water passes through the filter membrane module 18 and is discharged through the inverted trapezoidal drain port 19, completing the demulsification and separation process. After the filter membrane module 18 has been used for a period of time, the device is turned off, the sealing door plate 17 on the outside of the separation chamber 16 is opened, and the filter membrane module 18 is slid out of the separation chamber 16 for cleaning or replacement. After replacement, the sealing door plate 17 is closed, and the device can be put back into use.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
