Description

Technical Field

[0001] The utility model relates to the technical field of color electrophoretic coating, in particular to a recyclable color electrophoretic coating device. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to make the pigments and resin particles suspended in the electrophoretic liquid migrate in a directional manner and deposit on the substrate surface of one of the electrodes. The basic principle of electrophoretic coating is to immerse the workpiece in a water-soluble coating as an anode (anodic electrophoresis), and set up a corresponding cathode. Direct current is passed between the two electrodes, and the coating is evenly applied to the object by the physical and chemical effects generated by the current. The electrophoretic coating process involves multiple effects such as electrophoresis, electrodeposition, electrolysis, and electroosmosis. The electrophoretic coating process generally consists of four main processes: pretreatment before coating, electrophoretic coating, cleaning after electrophoresis, and drying of the electrophoretic coating film. Among them, the surface treatment of the workpiece before coating is an important part of electrophoretic coating, which mainly involves degreasing, rust removal, surface adjustment, phosphating, and other processes;

If these wastewaters are directly discharged without treatment, it will cause irreparable damage to the environment. The wastewater can only be recycled after treatment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a recyclable color electrophoretic coating device, comprising: a bottom plate 1, a stirring box 2, a feeding port 3, a stirring motor 4, a stirring shaft 5, a stirring blade 6, a serpentine pipe 7, a heating mechanism 8, a water pump 9, a filter box 10, a first screen 11, a cleaning plate 12, a connecting rod 13, an eccentric wheel 14, a first motor 15, a second motor 16, a limit rod 17 and a second screen 18;

[0029] When using the recyclable color electrophoretic coating device, if Figure 1As shown, a stirring box 2, a heating mechanism 8, a water pump 9 and a filter box 10 are arranged on the upper side of the bottom plate 1. Wastewater is added into the stirring box 2 from the feeding port 3, and then the precipitation agent is added into the inside of the stirring box 2. The stirring motor 4 is started, and the output shaft of the stirring motor 4 is fixedly connected to the stirring shaft 5. The outer side of the stirring shaft 5 is fixedly connected with a stirring blade 6. The rotating stirring shaft 5 will rotate with the stirring blade 6. The stirring blade 6 is arranged in an anisotropic manner, which increases the contact area between the stirring blade 6 and the wastewater, so as to facilitate the stirring of the wastewater in the stirring box 2, so that it can be fully stirred and mixed with the agent, accelerate the reaction of the agent and the wastewater, and thus reduce the reaction time.

[0030] like Figure 1 As shown, when the temperature of the added wastewater is low, it needs to be heated. The high temperature is conducive to the reaction between the agent and the wastewater, further reducing the reaction time between the harmful substances in the wastewater and the agent. A serpentine tube 7 is arranged in the side wall of the mixing box 2. The serpentine tube 7 is spiral, and the lower left side of the serpentine tube 7 is connected to the water outlet pipe of the heating mechanism 8. The water outlet of the serpentine tube 7 is connected to the water inlet of the heating mechanism 8, so that the heat energy generated by the heating mechanism 8 first enters from the lower side of the serpentine tube 7, which is convenient for the heat energy to transfer to the wastewater in the mixing box 2, reducing the energy loss, and starting the heating mechanism 8. The heating mechanism 8 will generate heat energy and transport it to the serpentine tube 7. The temperature of the wastewater heated by the serpentine tube 7 will rise, thereby reducing the reaction time;

[0031] like Figure 1 and Figure 2 As shown, after the wastewater reacts with the reagent, the wastewater in the mixing tank 2 will be separated into a mixture of water and sediment that can be directly discharged. When discharging, the stirring motor 4 needs to be started to prevent the sediment from being deposited on the lower side of the mixing tank 2 and blocking the water pump 9 during discharge;

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, start the water pump 9, the water pump 9 will pump out the mixture of sediment and water in the mixing box 2 and transport it to the upper side of the filter box 10. The first screen 11 is provided on the upper side of the interior of the filter box 10. The transported mixture will fall on the upper side of the first screen 11. Two cleaning plates 12 are provided on the lower side of the first screen 11, and the cleaning plates 12 are slidably connected to the first screen 11. The lower side of the cleaning plate 12 is slidably connected to the limiting rod 17. The limiting rod 17 has a limiting effect on the cleaning plate 12 to prevent the cleaning plate 12 from deflecting. The lower side of the cleaning plate 12 is rotatably connected to the connecting rod 13, and the connecting rod 13 is rotatably connected to the eccentric wheel 14. The cleaning plate 12, the connecting rod 13 and the eccentric wheel 14 are all symmetrical about the vertical center axis perpendicular to the first screen 11. The two eccentric wheels 14 are fixedly connected to the output shafts of the first motor 15 and the second motor 16 respectively. Start the first motor 15 and the second motor The rotation of the first motor 15 and the second motor 16 will make the corresponding cleaning plates 12 reciprocate up and down, and the cleaning plates 12 will push the sediment stuck in the first screen 11 to the upper side of the first screen 11. In addition, the first screen 11 is arranged at an angle to facilitate the mixture of wastewater and sediment to slide to the right side of the first screen 11. After the wastewater and sediment are filtered once, they will fall to the upper side of the second screen 18. The second screen 18 performs a secondary filtration on the mixture of wastewater and sediment, and the filtered water will fall to the lower side of the interior of the filter box 10. By opening the valve on the right side of the filter box 10, the qualified water can be discharged to the outside, thereby achieving the recycling of water resources and protecting the environment. In addition, the right side and front side of the filter box 10 are provided with side doors. By opening the corresponding side doors, the filter residue on the upper side of the first screen 11 and the filter residue on the upper side of the second screen 18 can be cleaned.
