Description

Technical Field

[0001] This utility model relates to the technical field of water-based epoxy zinc-rich paint production equipment, and in particular to a filtration device for the production of water-based epoxy zinc-rich paint. Background Technology

[0002] Waterborne epoxy zinc-rich paint, as an important heavy-duty anti-corrosion coating, is widely used in shipbuilding, bridges, steel structures, and other fields. Its production quality largely depends on the dispersibility of zinc powder and the purity of the paint. Therefore, efficient and fine filtration of the mixed paint to remove impurities and polymer particles is a crucial step in the production process.

[0003] In practical applications, existing filtration equipment suffers from the following problems: Most filtration equipment is single-stage filtration, with limited filtration accuracy, making it difficult to simultaneously remove both large particulate impurities and fine gel particles. The viscosity of paint is greatly affected by temperature. In low-temperature environments, the increased viscosity can lead to a sharp drop in filtration efficiency and even blockage of the filter element. Existing equipment lacks effective temperature control and viscosity management methods. Most filtration equipment has a single function and lacks mobility, making it difficult to adapt to the flexible production scheduling and allocation needs of modern workshops and different workstations.

[0004] Therefore, this utility model provides a filtration device for the production of water-based epoxy zinc-rich paint. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-efficiency filtration device that integrates multi-stage filtration, heating to reduce viscosity, easy maintenance, and flexible mobility, so as to solve the above-mentioned technical pain points and improve the production efficiency and product quality of water-based epoxy zinc-rich paint.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a filtration device for the production of water-based epoxy zinc-rich paint, comprising a fixed base plate.

[0022] Working principle: like Figures 1-6 As shown: By setting up a fixed base plate 1, a filter tank 2, and a heat treatment chamber 3, during use, the water-based epoxy zinc-rich paint slurry to be treated is pumped into the internal storage chamber 25 inside the filter tank 2 through the feed pipe 27. Inside the tank, the paint first undergoes primary coarse filtration through multiple first filter elements 26, where larger particles are trapped in the internal storage chamber 25. After primary filtration, the paint, under pressure, enters the filter channel 6 through the first connecting pipe 4. Here, the paint passes through the second filter element 62 for secondary fine filtration, further removing fine particles. The finely filtered paint can then enter the heat treatment chamber 3 via two paths: directly into the heating hood 5 for heating... Pipe 51 allows for the addition of additives via feeding pipe 36. Hand cranking handwheel 58 drives the first and second stirring rods 35 and 38 for mixing. The mixed material is then introduced into heating pipe 51 via inlet pipe 34. In heating pipe 51, a built-in heating plate heats the paint, increasing its temperature, decreasing its viscosity, and enhancing its fluidity. The conditioned paint is then discharged through discharge pipe 31, controlled by the first valve 52, to proceed to the next production process or packaging. A recovery tank 15 is located on one side of the heating treatment chamber 3, used to collect cleaning fluid or temporarily discharged materials. When cleaning or filter replacement is required, [the material can be recovered]. By removing the first limit pin 24 and the second limit pin 42, opening the top sealing cover 21 and disconnecting the first connecting pipe 4, the filter element can be easily removed. The pressure relief valve 61 can automatically open in case of abnormal pressure to ensure safety. The third valve 63 and the second connecting pipe 64 can be used for emergency discharge or cleaning. The entire process is centrally monitored and operated by the control panel 55. By setting the first filter element 26 and the second filter element 62 to form a two-stage filtration, impurities of different particle sizes can be classified and intercepted in sequence, which significantly improves the filtration accuracy and filtration efficiency, ensuring the purity and high quality of the water-based epoxy zinc-rich paint. The equipment adopts a design with multiple detachable connections, such as through the top... The top cover fixed by the first limiting ring 23 and the first limiting pin 24, the pipes connected by the sealing limiting ring 41 and the second limiting pin 42, and the top inspection plate 57 and inspection cover 32 make filter replacement, pipe cleaning and internal equipment maintenance very convenient, greatly reducing the downtime required for equipment maintenance.
