Description

201043441 VI. Description of the Invention: [Technical Field] The present invention relates to a melt filter which is installed at the front end of a plastic extrusion molding machine to remove contaminants of molten resin (deterioration) Inclusions such as impurities and impurities (hereinafter, in the present specification, contaminants and impurities are collectively referred to as inclusions), and a filter for filtering the molten resin, and a solution filter is a method for processing a plastic circulating material into a raw material. The filter is installed in a granulator and filters the molten resin. Ο 【Prior technology】

The melt of the conventional melt, the basic miscellaneous filter, the plug (4), the change of the filter type, please refer to the patent document i (Japanese Patent Publication No. 9_9, the Japanese Gazette), and the patent document 2 (曰本实公昭5卜0〇) Japanese Patent Publication No. 2234 (Japanese Unexamined Patent Publication No. Hei No. 07-515314) The subsequent process of processing the products of the products sold on the market is a transition device with a low life and a low life. In general, the cause of blockage of _, the device is mostly caused by contaminants, and the contaminant is the substance of the resin or the substance of the heterogeneous type, and there are also garbage and other types of impurities other than the resin. . According to the method, the frequency can be roughly classified according to the following methods: (1) Device type 'When the filter is clogged, it can be decomposed and replaced by one side. (2) Skate type _ _ replacement method, with double _ filter function. 4 201043441 (3) Make the belt-like filter, and when the surface is blocked, move the blocked part and update it. (4) The extension of the life-type type of filter, in the independent and replaceable filter, the two-piston type filter converter, which is set to _ on the flow path, and can be made more when the filter is clogged' The filter will be reversely cleaned by passing the resin in the side to the other side of the filter and reversing the cleaning process, extending the filtration time. 〇 (5) Extend the life type of the sputum, and use a screw to discharge the inclusions (4) to a part by scraping the board from the outer surface of the filter. For any-type transitioners, when the filter is clogged, it is a way to replace the new filter. However, as far as the conventional melt transition device is concerned, especially for the material based on the container recycling method, that is, the waste plastic material which is seriously polluted, it is difficult to cope with it, and although the life of the wealthy age can be prolonged a little, But it is not enough to meet the needs of users. In the conventional products, the method of using the self-cleaning method (4), (5). The problem of the method of the item (4) is that the resin filtered by one side of the filter flows to the plugged device of the other side, whereby the inclusions of the cleaning transition device are clogged, so that the superfine fat is again mixed with the inclusions. When the materials are mixed and discharged, the amount of resin to be cleaned is large and frequently operated, and a large amount of resin is present. For the use of waste plastics, the use of the finished product is poor and the practicality is more problematic. In the case of item (5), the inclusions are scraped off and concentrated by the scraper of one part and taken out to the outside by the portion of the filter which is retained, as a problem of the structure: not only garbage, pollutants The inclusions, and the resin to be filtered out, are also scraped together and accumulated in a circular filter in a cylindrical filter, and are discharged by a sieve. This is effective for materials with a low degree of contamination. For example, the plugging problem of the filter is generated in about 5 minutes in the operation of the general melt filter and the device, and is filtered for materials with a lot of inclusions such as garbage and pollutants. Not enough, thus increasing the discharge of the effective amount of resin. In this type, the resin attached to the outer periphery of the filter is discharged by a screen close to and parallel to the squeegee. Therefore, when the amount of inclusions is increased, in order to maintain the filtration performance and remove the inclusions as quickly as possible, the rotation speed of the rotating portion must be increased. Thereby, the amount of the resin to be filtered is largely concentrated on the squeegee, and the amount of the resin to be filtered other than the inclusions is also increased, the content of the inclusions is reduced, and it is difficult to increase the amount of the finished product recovered by the resin. Further, since the shape of the effluent is curled and thickened along the groove, it is in the form of a block and is difficult to post-process. Then, when the clogging of the filter continues and the performance is degraded, the filter must be replaced. However, since the replacement filter is a standardized filter cartridge, the common metal mesh cannot be used and the running cost is increased. In order to discharge the inclusions using the data network, the drive motor and the machine H of the device are increased to cause the device to become a faulty portion.
