It relates to a molten plastic filtration system. The invention is particularly useful for filtration in plastic production lines operating under high temperatures and pressures. to increase efficiency, facilitate in-system maintenance and cleaning processes, and improve product quality by 10 It relates to a molten plastic filtration system developed for improvement purposes. State of the Art During the processing of molten plastic in the production line, foreign particles and gases present within it... 15 Removing the phases from the system is of great importance in terms of the quality and homogeneity of the final product. It carries. Filter systems developed in this context are a fundamental element in plastic processing machines. It is included as equipment; it directly affects the efficiency and reliability of the production process. Especially suitable for operations under high temperature and pressure, requiring efficient decomposition of pollutants and 20 In processes requiring filtration elements to remain constantly clean, advanced systems specifically designed for this field are needed. The need for filter systems is increasing. Existing systems are used in plastics processing lines. It is limited to the traditional filtration units used; contamination cleaning, gas removal and It offers limited solutions in critical areas such as ease of maintenance. For example, US 10,974,177 B2 The system described in patent number 25 aims to remove contaminants from melted plastic. A filter system is described; contaminants accumulating on the surface of the filter element are removed by a scraper element. Cleaning is ensured through this scraper element, which is connected to the filter by a servomechanism. It aims to separate dirt by applying pressure to its surface. However, the system used in this process... Delicate structures like bellows cylinders are susceptible to deformation under high temperature and pressure, and require long-term care. This weakens the stability of the system during prolonged operation. Furthermore, the filtered contamination is 30%. There is no detailed and integrated discharge structure for the discharge of waste outside the system. WO Patent application number 2023 / 012656 A1 describes two filter elements for molten plastic material. A centrally located rotary cleaning system equipped with [specific equipment / instrument] is described. This 2 The system balances the contact between the scraper elements and the discharge outlet in the filter surfaces. Contaminations are removed by ensuring proper functioning of the scraper system. However, in this solution, the scraper system must be working correctly. Continuous rotational motion is required; this leads to mechanical complexity and maintenance This increases the need for it. Furthermore, since there is no quick-release clamp system in the body assembly... The production line may need to be shut down for an extended period for filter cleaning or maintenance. Gas removal 5 The process cannot be carried out in an integrated manner, and the gas phases affecting the plastic quality... The separation is insufficient. In patent number US 5,456,828A, it is vertically positioned. A filtration system that operates with multiple filter cartridges housed within a cylindrical body. It has been defined. In this system, filter cartridges located inside pipes surrounded by a heat transfer fluid, The polymer precisely controls the temperature, and the cartridges are easily replaceable. This system is designed with separate piping structures and heating circuits for each filter. Because of its components, it requires a costly and complex installation. It also has a scraper blade. There is no cleaning or automatic contamination removal system; manual intervention is required. The need for this continues. The fact that the filter elements do not work in an integrated manner with the gas removal process is also a factor. This causes the system to remain limited. 15 When the technical documents and known systems summarized above are evaluated, it is seen that the filter elements... Automatic and pressure-sensitive cleaning, continuous removal of contamination, degassing process. Integration with filtration allows for quick and labor-intensive opening / closing of the casing. It is observed that basic needs such as these are not fully met. In the known technique, plastic melt 20 stationary filter elements and these filters are used in systems designed to filter materials. Cleaning the accumulated contaminants requires manual intervention. This type of Replacement of filter elements in systems, maintenance process or cleaning, production line This causes delays, leading to losses in time and labor. Furthermore, the current situation... The mechanisms used to remove contaminants in systems have limited mobility. 25 its ability to direct contamination towards the screw pitch Blockages reduce filtration efficiency. In body assembly, body parts are generally joined using high-strength bolts. Designs where the filter elements are interconnected are preferred. However, this method requires the removal of the filter elements. 30 or requires the removal of each bolt individually when maintenance is needed, and especially In systems operating at high temperatures, this process causes significant time and labor losses. This also involves cleaning the molten plastic that adheres to the removed bolts and reassembling them. The lubrication and assembly process is laborious for the operator. 35 In current laser filter systems, filter screens are typically fastened with bolts, rivets, or wedges. They are fixed in place. These fixing methods are used on filter screens produced by laser cutting or electron beam. 3 This prevents the balancing of thermal stresses that occur on the filter during long-term use. This leads to serious structural deterioration in the sieve, such as cracks, deformations, and fractures. This situation both increases production costs and reduces the reliability of the system. Furthermore, in known systems, the gas removal process is usually performed by a separate unit, 5 It is unable to work in sync with the filtration process, and this is especially true for homogeneous and non-porous materials. This makes it difficult to obtain plastic products. Gases trapped within the plastic cause damage to the product surface. It causes a loss of quality by forming bubbles or structural voids. Current molten plastic filtration systems; the difficulty of the cleaning and maintenance process, body assembly 10 the impracticality of the methods, the inability to effectively remove contaminants, gas removal the inability of the process to work integrated with the system and structural problems occurring in the filter elements It has many disadvantages, such as deformations. For these reasons, a more efficient, maintenance-free system is needed. filter elements that facilitate ease of use, optimize contamination and gas removal. a new generation 15 that prevents deformation and enables the uninterrupted operation of the production line. A filtration system was needed. As a result, the disadvantages of the existing technology were addressed. The need for a molten plastic filtration system that eliminates this problem and the existing solutions The deficiency has made it necessary to make improvements in the relevant technical field.
