Embodiment 1

[0033] This embodiment is a filter system, which is composed of three parts: a filter core type melt filter 1, a recoil type washing screen changer 2, and a booster pump. Type melt filter 1 is connected, combined with figure 1 , the cartridge type melt filter 1 is composed of a fixed plate 11, a lower cover 12, a filter element 13, an upper cover 14 and an outer cylinder 4, the filter element 13 is installed between the upper cover 12 and the lower cover 14, combined Figure 4, the outer cylinder 4 is set on the filter element 13 between the upper cover plate 12 and the lower cover plate 14, the lower part of the lower cover plate 12 is fixed by the fixing plate 11, and the side wall of the lower cover plate 12 is provided with a melt inlet 121, The top is provided with a plurality of diversion ports 122 on the periphery of the filter element 13, and each diversion port 122 is connected with the melt inlet 121 in the lower cover plate 12; the filter element 13 is composed of a...

Embodiment 2

[0040] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that: a layer of heating plate 27 is arranged on the outer wall of the screen changer cavity 26; there is one hydraulic cylinder 28, and the hydraulic cylinder 28 is provided with two position rods , each position rod 281 corresponds to a plunger 21 . The setting of the heating plate 27 ensures that the melt maintains a constant temperature during conveying and filtering, and the same hydraulic cylinder 28 can control the states of the two plungers.

Abstract

The invention relates to a filtering system and belongs to the technical field of fiber processing auxiliary equipment. The filtering system is composed of three parts: a backwashing type screen washing and exchanging device, a booster pump and a filter element type melt filter, wherein the booster pump is separately connected with the backwashing type screen washing and exchanging device and the filter element type melt filter; the backwashing type screen washing and exchanging device comprises a plunger, a distribution plate, a screen exchanging device cavity and a hydraulic cylinder; the filter element type melt filter is composed of a lower cover plate, a filter element, an upper cover plate and an outer barrel. The filtering system provided by the invention is applied to filtering melts of reclaimed materials such as chemical fiber waste materials and the like and has the advantages of being high in filtering precision, stable to feed and the like.

Description

technical field [0001] The invention relates to a filter system and belongs to the technical field of fiber processing auxiliary equipment. Background technique [0002] In the process of chemical fiber production, waste silk will inevitably be generated due to changes in materials, equipment, process technology and product variety switching. With the sharp increase in chemical fiber production capacity, chemical fiber waste is also increasing. If not utilized, on the one hand, solid waste or even white garbage will be formed; on the other hand, fossil resources such as petroleum are non-renewable, and the chemical fiber industry downstream of petrochemical industry urgently needs to recycle and reuse this part of waste. In the process of waste collection, storage and transportation, solid impurities will be included. If they are directly reused without filtering, the next process of recycled materials, as well as recycled spinning, direct injection recycled sheet, injectio...
