Description

Technical Field

[0001] The utility model relates to the technical field of paint production, in particular to a stainless steel tubular filtering device used for a paint discharge port. Background Art

[0002] The existing paint production enterprises in China are very large and very small, with a huge difference in size. Large paint production enterprises, because of their sufficient funds, huge production capacity and stable market demand, are generally equipped with special intelligent filtering equipment. According to customer needs, the operator issues instructions, and the intelligent equipment will automatically adjust the filter screens with different mesh sizes to obtain paint products with different mesh sizes (coarse and fine); the end of the filtering equipment is equipped with high-speed automatic filling equipment, and the filtered paint products are directly fed into the filling equipment through the pipeline for filling and storage, and the production process is completed. The disadvantage is that the investment is large and it is not suitable for small and medium-sized paint processing enterprises;

[0003] At present, in order to save investment and production costs, the filtering method used by small and medium-sized paint processing enterprises is usually to wrap a piece of filter cloth (textile material, metal material) of corresponding mesh number at the discharge port, and achieve the filtering effect through manual extrusion;

[0004] However, the filter cloth is cheap, but has a short service life and cannot be cleaned thoroughly because it needs to be rubbed manually during the cleaning process. The warp and weft of the filter screen are easily damaged and deformed, and it must be discarded after cleaning 3 to 4 times. Moreover, the filter cloth is manually wrapped at the discharge port, and the sealing is not strong. Paint often leaks during the discharge process, making the workplace dirty and messy. The operator's body is directly exposed to the paint due to the leakage. If this continues for a long time, it will cause certain harm to the body. The leakage will also cause a great waste of finished paint products, thereby increasing the production cost of the enterprise. Therefore, we need to propose a stainless steel tubular filter device for the paint discharge port. Utility Model Content
