Description

Technical Field

[0001] This utility model relates to the field of waste paint recycling technology, specifically a paint waste residue paint-water separation device. Background Technology

[0002] In modern industrial production systems, painting processes are widely used in numerous fields such as automobile manufacturing, furniture production, shipbuilding, and architectural decoration. Painting not only gives products an aesthetically pleasing appearance but also plays a vital role in protecting product surfaces and extending their lifespan. However, the painting process inevitably generates a large amount of paint waste and paint-water mixtures. These paint waste and paint-water mixtures contain large amounts of harmful substances such as organic solvents, heavy metal ions, and resins. If discharged directly into the environment without effective treatment, they will cause serious pollution to soil, water bodies, and the atmosphere, threatening ecological balance and human health.

[0003] Currently, paint waste separation equipment mainly uses sedimentation tanks to effectively separate paint waste and paint water, so that the separated paint waste and paint water can be further processed and recycled. Through paint water separation, the pollutant content in the paint water can be reduced, and the difficulty and cost of subsequent treatment can be reduced. At the same time, the separated paint waste can also be treated harmlessly or utilized as a resource, such as being made into building materials, fuel, etc.

[0004] Traditional sedimentation tank treatment methods require the addition of paint mist coagulants. These coagulants can cause paint waste to quickly coagulate into larger particles in the paint water, thereby accelerating the settling speed of the paint sludge and improving the paint-water separation efficiency. However, the current process of manually adding paint mist coagulants is inefficient, and the concentration of the coagulants is inconsistent due to insufficient stirring, which will reduce the sedimentation effect of the sedimentation tank.

[0005] Therefore, in order to address the above problems, the applicant needs to design a paint waste and paint water separation device to solve the problem. Utility Model Content

[0006] The purpose of this utility model is to provide a paint waste residue paint water separation device to solve the problems mentioned in the background art above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paint waste residue paint-water separation device, including a sedimentation tank, with supporting feet on the bottom surface of the sedimentation tank; a partition plate with holes is provided inside the sedimentation tank, dividing the sedimentation tank into a sedimentation chamber and a water chamber; a fixed frame is provided inside the sedimentation chamber, with a hexagonal inclined tube on the fixed frame; a sedimentation hopper is provided below the sedimentation chamber for buffering paint liquid; a water outlet pipe is connected to the water chamber and is connected to an external liquid storage container; a chemical tank is provided inside the sedimentation chamber for preparing paint mist coagulant; an auxiliary mechanism is provided on the chemical tank for stirring and mixing the chemical liquid in the chemical tank.

[0008] Furthermore, the auxiliary mechanism includes an inlet pipe, and the output end of the inlet pipe is connected to a pressure pump. The outlet end of the pressure pump is fixedly connected to an outlet pipe, and the outlet end of the outlet pipe extends into the sedimentation chamber.

[0009] Furthermore, a base is fixedly provided on the bottom surface of the pressurizing pump, and a support seat is fixedly provided on the bottom surface of the base.

[0010] Furthermore, a support frame is fixedly installed on the support base, and the support frame is fixedly connected to the liquid medicine tank.

[0011] Furthermore, a support plate is provided on the support frame, and a servo motor is fixedly installed on the support plate. A rotating rod is provided at the output end of the servo motor, and a stirring blade is fixedly installed on the rotating rod.

[0012] Furthermore, the bottom of the sedimentation hopper is connected to a discharge pipe, and a control valve is installed on the discharge pipe. The outlet end of the discharge pipe extends to the outside of the sedimentation tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the paint waste residue paint water separation equipment can deliver fully stirred and mixed paint mist coagulant into the sedimentation tank, thereby improving the sedimentation effect and working efficiency, as detailed below:

[0014] In operation, the paint waste and water separation equipment first enters the sedimentation chamber, while a pre-mixed paint mist coagulant solution is prepared in the chemical tank. A servo motor in the auxiliary mechanism drives the rotating rod and stirring blades for powerful stirring, ensuring a highly uniform concentration of the chemical solution. The homogenized solution is continuously and stably pumped into the sedimentation chamber at a certain pressure through a pressurized pump and outlet pipe, where it fully mixes and contacts the incoming paint waste and water mixture. Under the action of the paint mist coagulant, the waste quickly coagulates into larger particles and slides down into the sedimentation hopper below for concentration and buffering. Finally, it can be periodically and controllably discharged and collected through the bottom discharge pipe. The relatively clear water separated flows into the water chamber through holes in the partition and is eventually discharged to an external storage container through the outlet pipe, completing the efficient separation of paint and water, thereby improving sedimentation effect and working efficiency.

[0020] 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.

[0021] like Figures 1-4As shown, the present invention discloses a paint waste residue paint-water separation device, including a sedimentation tank 1, with a support foot 10 on the bottom surface of the sedimentation tank 1. A partition 11 is provided inside the sedimentation tank 1, and holes 12 are provided on the partition 11. The partition 11 divides the sedimentation tank 1 into a sedimentation chamber 13 and a water chamber 14. A fixing frame 16 is provided inside the sedimentation chamber 13, and a hexagonal inclined tube 17 is provided on the fixing frame 16. A sedimentation hopper 18 is provided below the sedimentation chamber 13, and the sedimentation hopper 18 is used to buffer the paint liquid. A water outlet pipe 15 is connected to the water chamber 14, and the water outlet pipe 15 is connected to an external liquid storage container. A chemical tank 19 is provided inside the sedimentation chamber 13, and the chemical tank 19 is used to prepare paint mist coagulant. An auxiliary mechanism 2 is provided on the chemical tank 19, and the auxiliary mechanism 2 is used to stir and mix the chemical liquid in the chemical tank 19.

[0022] The auxiliary mechanism 2 includes an inlet pipe 25, and the output end of the inlet pipe 25 is connected to a pressure pump 26. The outlet end of the pressure pump 26 is fixedly connected to an outlet pipe 27, and the outlet end of the outlet pipe 27 extends into the sedimentation chamber 13. By setting the auxiliary mechanism 2 including the pressure pump 26, the automated and continuous delivery of the paint mist coagulant solution is realized, which improves the dosing efficiency. The forced delivery of the pressure pump 26 can also make the solution enter the sedimentation chamber 13 at a certain pressure and flow rate. Compared with simple pouring, it is more conducive to the initial dispersion of the solution in the inlet water, creating better conditions for subsequent uniform mixing.

[0023] A base 28 is fixedly mounted on the bottom surface of the pressure pump 26, and a support 29 is fixedly mounted on the bottom surface of the base 28. The base 28 and the support 29 provide a stable installation foundation for the pressure pump 26, effectively reducing the vibration of the pressure pump 26 during operation, preventing equipment displacement, loosening of connections or damage caused by vibration, enhancing the working stability and reliability of the pressure pump 26 and the entire auxiliary mechanism 2, ensuring the continuity and stability of the drug delivery, and providing a guarantee for the long-term stable operation of the equipment.

[0024] A support frame 20 is fixedly installed on the support base 29, and the support frame 20 is fixedly connected to the liquid medicine tank 19. The support frame 20 firmly connects the support structure of the pressure pump 26 to the liquid medicine tank 19, integrating the key components of liquid medicine storage, stirring and transportation into a more compact and stable overall module, thereby improving the structural rigidity and integrity of the equipment.

[0025] A support plate 21 is provided on the support frame 20, and a servo motor 22 is fixedly installed on the support plate 21. A rotating rod 23 is provided at the output end of the servo motor 22, and a stirring blade 24 is fixedly installed on the rotating rod 23. The servo motor 22 drives the rotating rod 23 and the stirring blade 24 to perform mechanical stirring in the liquid tank 19. This ensures that the paint mist coagulant solution in the liquid tank 19 is strongly and uniformly mixed, avoiding the problem of local concentration being too high or too low. Preparing a uniform concentration of the liquid solution is a prerequisite for ensuring that it reacts effectively and fully with the paint waste in the sedimentation chamber 13 and achieves the best coagulation and sedimentation effect, which directly improves the overall separation efficiency of the sedimentation tank 1.

[0026] The bottom of the sedimentation hopper 18 is connected to a discharge pipe, and a control valve is installed on the discharge pipe. The outlet end of the discharge pipe extends to the outside of the sedimentation tank 1. The discharge pipe with a control valve is set at the bottom of the sedimentation hopper 18 so that the concentrated paint sludge can be discharged from the equipment in a convenient and controllable manner.

[0027] Working Principle: When using this paint waste and paint water separation equipment, the paint waste and paint water mixture to be treated first enters the sedimentation chamber 13. At the same time, the paint mist coagulant solution is pre-mixed in the chemical tank 19. The servo motor 22 in the auxiliary mechanism 2 drives the rotating rod 23 and the stirring blade 24 to perform strong stirring, ensuring that the concentration of the chemical solution is highly uniform. The homogenized chemical solution is continuously and stably pumped into the sedimentation chamber 13 at a certain pressure through the outlet pipe 27 via the pressurization pump 26, and fully mixes and contacts the inflowing paint waste and paint water mixture. Under the action of the coagulant, the waste residue quickly coagulates into larger particles. When the mixed liquid flows through the hexagonal inclined tube 17 component, the coagulated paint residue particles settle rapidly on the huge sedimentation surface area provided by the inclined tube and slide down into the sedimentation hopper 18 below for concentration and buffering. Finally, it can be periodically and controllably discharged and collected through the discharge pipe at the bottom. The relatively clear water separated flows into the water chamber 14 through the holes 12 on the partition 11 and is finally discharged to the external storage container through the water outlet pipe 15, completing the efficient separation of paint and water, thereby improving the sedimentation effect and working efficiency.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
