Embodiment 1

[0025] Embodiment 1: a kind of melt filter, such as figure 1 As shown, include the casing 9 that is supported as the main body, the inside of the casing 9 is provided with a cylindrical through hole that is transparent up and down, and the front portion of the casing 9 is provided with a feed port 14 that communicates with the cylindrical through hole. The rear part is provided with a filter member replacement port 15 connected with the cylindrical through hole, and a rotatable support tube 7 is arranged in the cylindrical through hole, and the support tube 7 is driven by the rotating drive mechanism II5 to rotate, and the support tube 7 can pass through belt, The chain or gear transmission mode is connected and matched with the rotary drive mechanism II5, and the connection mode between the support tube 7 and the rotary drive mechanism II5 in this embodiment adopts a gear transmission mode. Such asfigure 1 As shown, the upper part of the support tube 7 is fixed with a driven ...

Embodiment 2

[0036] Embodiment 2: A kind of melt filter, when the opening length of the filter member replacement port 15 on the circumference of the cylindrical through hole is greater than 1 / 4 of the circumferential length of the cylindrical through hole, and the filter member replacement port 15 is on the circumference of the cylindrical through hole When the length of the opening is less than one-third of the length of the circumference of the cylindrical through hole, if the molten material is not close to the replacement port 15 of the filter member and is not enough to naturally solidify by exchanging heat with the air, a cooling system is installed behind the replacement port 15 of the filter member Cool down (the cooling system can use wind blowing to cool down, water pipe heat exchange to cool down, etc.). Other structures are the same as in Embodiment 1.

Embodiment 3

[0037] Embodiment 3: A kind of melt filter, filter component is the filter cylinder that is transparent up and down, is provided with the sieve hole II that is used for filtering on the side of filter cylinder, on the support pipe 7 that filter cylinder sleeves, the outer surface of filter cylinder and The inner wall of the cylindrical through hole is in sealing sliding contact, and when the filter cartridge is rotating, the support tube 7 provides the main driving force for the filter cartridge. The upper part of the cylinder of the screw guide rod 6 is provided with a groove, the wall of the groove is provided with a pin hole I, the lower part of the output shaft of the reducer I is provided with a pin hole II, and the lower part of the output shaft of the reducer I is inserted in the concave In the slot, the pin hole I corresponds to the pin hole II, and a positioning pin for fixing is inserted in the pin hole I and the pin hole II. Other structures are the same as in Embod...

Abstract

The invention provides a melt filter, thereby solving problems of high cost and complex structure of an external cooling system at the replacement part of a filter component of the melt filter. The melt filter comprises a sleeve shell serving as a main body support, a cylindrical through hole which is communicated up and down is formed in the sleeve shell; a feeding hole communicated with the cylindrical through hole is formed in the front part of the sleeve shell; a filtering component replacing opening communicated with the cylindrical through hole is formed in the rear part of the sleeve shell; a rotatable supporting pipe is arranged in the cylindrical through hole, the supporting pipe is driven by a rotary driving mechanism II to rotate, a rotatable spiral material guide rod is arranged in the supporting pipe, the spiral material guide rod can rotate independently relative to the supporting pipe, and the spiral material guide rod is driven by the rotary driving mechanism II to rotate; a screw rod cavity II is formed between the inner wall of the supporting pipe and the spiral material guide rod, sieve holes I for melt to circulate are evenly formed in the middle of the supporting pipe, and the sieve holes I are used for communicating the feeding hole with the screw rod cavity II; and a gap for mounting the filtering component is formed between the supporting pipe and the wall surface of the cylindrical through hole.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a melt filter. Background technique [0002] The melt filter is mainly used in the plastic extrusion industry. It is a kind of equipment for purifying the plastic melt. There are three main directions for the existing melt filter screen replacement technology: (1) The column type is more widely used and the earlier one is And the plate type melt filter, the main disadvantage is that the mesh needs to be replaced manually, which cannot be automated; (2) the scraper type melt filter has the advantage that it does not need to replace the mesh frequently and realizes automation, but the disadvantages are also obvious. The core component filter mesh is restricted by existing processing technology, its filtration accuracy and service life are very low, and the cost of the mesh is very high; (3) mesh belt type melt filter, patent documents such as CN207077744U, CN205095519U, CN108688127...
