Description

Technical Field

[0001] This utility model belongs to the field of fatty amine wastewater treatment technology, and in particular relates to a fatty amine wastewater retreatment device. Background Technology

[0002] Fatty amine wastewater is a common type of industrial wastewater in chemical production. It mainly comes from the production process of fatty amines and their derivatives, such as the production of fabric softeners, surfactants, and cosmetic raw materials.

[0003] To avoid pollution caused by fatty amine wastewater, appropriate fatty amine wastewater treatment equipment is needed for its further treatment. During treatment, the fatty amine wastewater and a suitable coagulant are placed into the equipment for mixing and reaction. This causes suspended solids and colloids in the wastewater to coagulate into larger particles and settle. However, during the addition of coagulant, large quantities are often added simultaneously, leading to coagulation and uneven dispersion. This prevents the effective components (such as Al³⁺ and Fe³⁺) from being fully released, reducing the charge neutralization / bridging effect with pollutants. The resulting flocs are loose, small in size, and have poor settling performance, thus reducing the effectiveness of fatty amine wastewater treatment. Utility Model Content

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model provides a device for re-treating fatty amine wastewater, such as... Figure 1-4As shown, the fatty amine wastewater retreatment device includes: a treatment tank 1 for treating fatty amine wastewater; a stirring rack 2 assembled in the treatment tank 1, wherein the treatment tank 1 and the stirring rack 2 are provided with a mixing mechanism for driving the stirring rack 2 to rotate and mixing the fatty amine wastewater and coagulant; a placement tank 3 fixedly installed on the treatment tank 1 for placing the coagulant, wherein the placement tank 3 is provided with a mounting cover 4, and a dispersion screen 5 for dispersing the coagulant is fixedly installed on the mounting cover 4; and a dispersion mechanism assembled on the treatment tank 1 and the mounting cover 4 for driving the dispersion screen 5 to vibrate and disperse the coagulant.

[0022] In this embodiment, when treating fatty amine wastewater, the wastewater is placed into treatment tank 1, and a certain amount of coagulant is placed into placement tank 3. The treatment process is carried out using OMRON... The controller of the E5CC-QX2ASM-800 starts the mixing mechanism and, through the controller, starts the dispersing mechanism, causing the dispersing screen 5 and the mounting cover 4 to vibrate. This effectively disperses the coagulant as it passes through the dispersing screen 5, preventing clumping and ensuring that the coagulant is evenly dispersed in the wastewater. Because coagulant clumping is avoided, the effective components in the coagulant (such as Al³⁺ and Fe³⁺) can be fully released, giving full play to their charge neutralization / bridging effect with pollutants, improving reaction efficiency. After the effective components are fully released, the generated flocs are more compact and have larger particle sizes, significantly improving settling performance, thereby enhancing the treatment effect on fatty amine wastewater. After treatment, the treated water can be discharged from the treatment tank 1. Through the entire device, fatty amine wastewater can be treated, and the coagulant can be evenly dispersed and fully mixed with the fatty amine wastewater, allowing the effective components in the coagulant to be fully released, thereby improving the treatment effect on fatty amine wastewater.

[0023] In a further preferred embodiment of this utility model, a placement rack 6 is fixedly installed on the processing box 1. The placement rack 6 and the stirring rack 2 are rotatably connected, and a first servo motor 7 is fixedly installed on the placement rack 6. The output shaft of the first servo motor 7 is connected to the top of the stirring rack 2 through a coupling. The first servo motor 7 is used to drive the stirring rack 2 to rotate and stir and mix the fatty amine wastewater and coagulant.

[0024] In this embodiment, when it is necessary to stir and mix fatty amine wastewater and coagulant, the first servo motor 7 is started by the controller, and its output shaft drives the stirring frame 2 to rotate in the treatment tank 1 through the coupling, thereby realizing the stirring and mixing operation of fatty amine wastewater and coagulant, allowing the two to fully mix and react, and improving the wastewater treatment effect.

[0025] In a further preferred embodiment of the present invention, the dispersing mechanism includes: a second servo motor 8 fixedly installed on the outer wall of one side of the processing box 1; a horizontal shaft 9 rotatably installed on the processing box 1, wherein the output shaft of the second servo motor 8 is connected to one end of the horizontal shaft 9 via a coupling, and a protrusion 10 is fixedly sleeved on the horizontal shaft 9, the protrusion 10 being located below the dispersing mesh plate 5, and the protrusion 10 being used to squeeze the dispersing mesh plate 5.

[0026] In this embodiment, when it is necessary to disperse the coagulant, the second servo motor 8 is activated by the controller, driving the horizontal shaft 9 to rotate. This causes the protrusion 10, which is fixedly sleeved on the horizontal shaft 9, to rotate as well. During the rotation, the protrusion 10 squeezes the dispersing screen 5. At this time, the dispersing screen 5 and the mounting cover 4 vibrate, so that the coagulant is effectively dispersed when passing through the dispersing screen 5, avoiding agglomeration and ensuring that the coagulant is evenly dispersed in the wastewater. Because coagulant agglomeration is avoided, the effective components in the coagulant (such as Al³⁺) are more effectively dispersed. + Fe³ + It can be fully released, giving full play to its charge neutralization / bridging effect with pollutants, improving reaction efficiency. After the effective components are fully released, the generated flocs are more compact and larger in size, and the settling performance is significantly improved, thereby enhancing the treatment effect on fatty amine wastewater.

[0027] In a further preferred embodiment of this utility model, the mounting cover 4 and the placement box 3 are provided with a reset mechanism for resetting the mounting cover 4 and the dispersing mesh plate 5 after compression. The reset mechanism includes: a slide rod 11 fixedly installed at the bottom of the placement box 3, a slider 13 slidably installed on the slide rod 11, and the slider 13 is fixedly connected to the outer wall of the mounting cover 4; and two springs 12 sleeved on the slide rod 11, with the two springs 12 located on both sides of the slider 13.

[0028] In this embodiment, when the protrusion 10 of the dispersion mechanism squeezes the dispersion screen plate 5, the mounting cover 4 drives the slider 13 to move upward on the slide rod 11, squeezing the spring 12 on one side; when the protrusion 10 rotates away from the dispersion screen plate 5, the squeezed spring 12 returns to its original state, pushing the slider 13 to drive the mounting cover 4 and the dispersion screen plate 5 to reset downward. At the same time, the spring 12 on the other side also plays a role in assisting stability and buffering the reset process. This process is repeated, causing the mounting cover 4 and the dispersion screen plate 5 to vibrate, thus dispersing the coagulant.

[0029] In a further preferred embodiment of the present invention, the placement box 3 is provided with a dispersing frame 14 for dispersing the coagulant in the placement box 3, and the placement box 3 and the horizontal shaft 9 are provided with a driving mechanism for driving the dispersing frame 14 to rotate and disperse the coagulant in the placement box 3.

[0030] In this embodiment, when the horizontal axis 9 rotates under the drive of the second servo motor 8, the drive mechanism moves accordingly, thereby causing the dispersing frame 14 to rotate in the placement box 3 to disperse the coagulant in the placement box 3, and then the coagulant is further dispersed through the dispersing mesh plate 5.

[0031] In a further preferred embodiment of the present invention, the driving mechanism includes: a placement shaft 15 rotatably mounted on the placement box 3, a bevel gear 16 fixedly sleeved on both the placement shaft 15 and the disassembly frame 14, and the two bevel gears 16 meshing with each other; two synchronous pulleys 17 fixedly sleeved on the placement shaft 15 and the horizontal shaft 9 respectively, and a synchronous belt 18 sleeved on the two synchronous pulleys 17.

[0032] In this embodiment, when the second servo motor 8 drives the horizontal shaft 9 to rotate, the synchronous wheel 17 on the horizontal shaft 9 rotates accordingly. Through the transmission action of the synchronous belt 18, the synchronous wheel 17 on the placement shaft 15 rotates, thereby causing the placement shaft 15 to rotate. When the placement shaft 15 rotates, the bevel gear 16 on it rotates accordingly. Since it meshes with the bevel gear 16 on the dispersing frame 14, it drives the dispersing frame 14 to rotate, thereby dispersing the coagulant in the placement box 3.

[0033] In a further preferred embodiment of the present invention, the processing box 1 is provided with a cleaning mechanism for cleaning the sediment generated in the processing box 1. The cleaning mechanism includes: a cleaning auger 19 rotatably installed in the processing box 1; and a third servo motor 20 fixedly installed on one side of the outer wall of the processing box 1. The output shaft of the third servo motor 20 is connected to one end of the cleaning auger 19 through a coupling.

[0034] In this embodiment, when cleaning the impurities at the bottom of the processing tank 1, the discharge pipe on one side of the processing tank 1 is opened. The discharge pipe is located on one side of the cleaning auger 19. When using the cleaning mechanism, the third servo motor 20 is started by the controller. Its output shaft drives the cleaning auger 19 to rotate through the coupling. During the rotation, the cleaning auger 19 pushes the sediment to the outside of the processing tank 1.

[0035] In summary, compared with related technologies, this device can treat fatty amine wastewater and can evenly disperse the coagulant and fully integrate it with the fatty amine wastewater, allowing the effective components in the coagulant to be fully released, thereby improving the treatment effect of fatty amine wastewater.
