Description

Technical Field

[0001] This utility model relates to the field of screen changer technology, specifically to a screen changer fluid slag removal wheel that is easy to clean. Background Technology

[0002] In the melt extrusion molding process of materials such as plastics, chemical fibers, and rubber, impurities are inevitably contained in the melt, such as carbonized particles, gels, metal shavings, or foreign objects in the raw materials. If these impurities enter the mold, they will cause product defects, broken filaments, uneven thickness, or even blockage of the mold, which will seriously affect product quality and production continuity. Therefore, a screen changer must be installed between the extruder and the mold. Its core function is to install a high-precision filter screen on the melt flow channel to intercept and remove these impurities.

[0003] Screen changer technology has evolved from manual to automatic. Manual screen changers require stopping the machine and disassembling the equipment to replace the filter screen, which is inefficient and wastes a lot of materials. They can no longer meet the needs of modern continuous production. Currently, the mainstream is the automatic screen changer, among which the dual-station screen changer is particularly widely used. This type of screen changer usually has two filtration stations, one in working state and the other in standby state. When the working filter screen increases the pressure difference across it due to the accumulation of impurities to a set value, the system automatically switches to the standby filter screen station, thereby realizing screen replacement without stopping the machine.

[0004] However, existing dual-station screen changers, especially their core filtration and deslagging unit, still have significant technical drawbacks. First, cleaning and maintenance are inconvenient. When the filtration station is switched, the screen clogged with impurities needs to be removed for cleaning. Traditional designs often require disassembling the entire deslagging wheel or plunger assembly to thoroughly clean the screen and its flow channels. This process is not only time-consuming and labor-intensive, increasing the labor intensity and downtime of workers, but also poses safety risks when handling high-temperature polymers. Second, cleaning is incomplete. Conventional cleaning methods often use external scraping or high-pressure gas reverse blowing, but these are only effective against stubborn impurities hidden deep inside the micropores of the screen and in the dead corners of the flow channels. The residual impurities will gradually affect the flow channel's smoothness and contaminate the pure melt when it is put into use again, becoming a potential hazard affecting product quality. Utility Model Content

[0005] This invention provides a fluid descaling wheel for a screen changer that is easy to clean. Through the use of an opening and closing mechanism, it can achieve efficient online reverse self-cleaning, greatly improving maintenance efficiency. It can use the pressure of the clean fluid itself to flush away impurities clogging the main filter plate from the inside out, resulting in a thorough and rapid cleaning effect. No parts need to be disassembled, and production does not need to be interrupted, significantly reducing equipment maintenance time and labor costs, and improving overall production efficiency. It uses two independent descaling wheel shafts as core working units, forming a redundant system. When one shaft is performing the above cleaning operation, the other shaft can immediately take over all filtration work, ensuring a completely uninterrupted production process and achieving true continuous operation. This adjustable capability can optimize the filtration effect and stabilize system pressure when facing materials of different viscosities or with different impurity contents, further improving product quality and production stability.

[0029] The circulation mechanism comprises two sets, each set located within each slag-removing wheel shaft 8. Each set includes a connecting component, a main flow chamber 13, and a secondary flow chamber 11. The main flow chamber 13 and the secondary flow chamber 11 are both located within the slag-removing wheel shaft 8.

The main flow chamber 13 and the secondary flow chamber 11 are connected, and one end of the secondary flow chamber 11 is funnel-shaped to ensure usability. The model of the opening and closing cylinder 4 can be selected from those available on the market as needed, which will not be elaborated here. The opening and closing cylinder 4 controls the opening and closing plug 6 to control the connection between the main flow chamber 13 and the secondary flow chamber 11, so that when the main flow chamber 13 is being cleaned, backflow control can be performed to complete the cleaning.

[0032] Specifically, the connecting components include a main connection port 5 and a secondary return port 7. There are two main connection ports 5, which are respectively opened on both sides of the main flow cavity 13, and the secondary return port 7 is opened on one side of the secondary return port 7.

[0033] In this embodiment: the main port 5 connects the two sides to complete the filtration. The secondary return port 7 can discharge the filtered solution during normal use, and can be refluxed during cleaning to clean the main port 5 in reverse.
