Problems solved by technology

[0010] The regeneration process is complex and harmful to operators
And after repeated regeneration, the sintered felt will also produce pore size changes, which will affect the filtering effect
Although domestic manufacturers use domestic sintered felt to make melt filter elements, it is difficult to meet the requirements in terms of pore size uniformity and processing resistance.

Embodiment Construction

[0029] Such as Figure 1-2 As shown in , a melt filter used in the production of spandex includes a support frame 1, a filter cartridge 2 and a connector.

[0030] Wherein the support frame 1 is made of a stainless steel punched plate, specifically, the stainless steel plate is punched and then rolled into a cylinder, and the two edges are welded together to form a hollow cylinder. It can also be processed by directly punching holes on the steel pipe.

[0031] The filter cartridge 2 is a hollow cylinder made of stainless steel sintered mesh processed by vacuum sintering of multi-layer stainless steel mesh. The stainless steel sintered wire mesh includes at least a five-layer structure of a protective layer 26, a control layer 25, a dispersion layer 24, a skeleton layer 23 and a skeleton layer 22 from outside to inside. More preferably, a diffusion layer 21 is added inside the skeleton layer. The control layer 25 preferably adopts a reverse weaving net, especially a reverse ...

Abstract

The invention relates to a melt filter element for spandex production. The melt filter element comprises a support frame and a filter element cartridge, wherein the filter element cartridge is sleeved on the support frame, is integrally welded with the support frame and is a hollow cylinder formed by welding a stainless steel sintered mesh. The stainless steel sintered mesh sequentially comprises a protection layer, a control layer, a diffusion layer, a first framework layer and a second framework layer from outside to inside. The melt filter element for spandex production is simple in structure, low in initial pressure difference, slow in pressure drop and rise, fine in filtering effect and low in cost, and has excellent social and economic values.

Description

technical field [0001] The invention relates to a melt filter core, in particular to a melt filter core used in spandex production. Background technique [0002] The quality of polyester melt in spandex spinning production is a key link in the spandex production process. Since the diameter of the spun filaments is very thin and the spinneret holes are small, any impurities or gel particles are not allowed to be mixed in the melt, so In the process of high-speed melt spinning, in order to improve spinning quality and ensure production stability, filters, especially melt filter elements, are essential and critical components. [0003] The melt filter element in spandex production is mainly used to filter out impurities and particles in the liquid, and most of them are made of metal fiber sintered felt folded into a corrugated shape. In order to ensure the quality of the factory, the filter accuracy is very high. Therefore, the current filter elements mostly rely on imports, ...
