Recently, the double-column back flush 570 developed by the Batong Intelligent screen changer division was successfully assembled. This type of screen changer is a high-efficiency, high-quality filter. First of all, this type of melt filter adopts a four-channel four-screen structure. The four screens work simultaneously, without interrupting the material flow or the product, and the screen can be changed without stopping. This design greatly increases the filtration area and meets the production requirements of higher output and higher quality. At the same time, an exhaust system is designed to fully remove the gas mixed in the material and the porous plate to be replaced, prevent the gas from forming in the product during the screen change process, and improve the quality of the product. Secondly, the melt filter also has a backwashing function, realizing online backwashing of the filter screen, and the filter screen can be reused more than 200 times. This design not only avoids frequent screen changes, but also saves production costs and increases production efficiency. In addition, the double-column backwash melt filter also has good sealing characteristics, rigid sealing, and long service life. It is suitable for high-capacity, high-efficiency, high-output continuous operation of large-scale extrusion equipment, especially for the processing of recycled plastics and the addition and utilization of a large proportion of recycled plastics. Finally, according to user needs, the melt filter can be specially designed and processed in various sizes to better meet different production needs. In short, the double-column backwash melt filter is an efficient and high-quality filter with the advantages of automatic screen washing, increased production and energy saving, and production cost saving. It is suitable for the extrusion production of different materials and different products, and is an indispensable equipment in the plastic extrusion production process.

Recently, Batong Intelligent successfully provided a 20T positioner for a valve factory in Zhengzhou to match its 3*3 cross welding manipulator. The equipment is mainly used for welding large valves such as butterfly valves with a diameter of less than 4000mm. This article will analyze the application cases of the equipment in detail.
