Embodiment Construction

[0030] combine Figure 1 ~ Figure 3 , to further illustrate the present invention:

[0031] Such as Figure 1 ~ Figure 3 As shown, an ultrafine particle filter device based on electrospinning technology is used for filtering air containing ultrafine particles, including: a main body box 1 with a sealed cavity, a filter box with an air inlet and an air outlet 4 and the filter baffle 2 and the filter baffle 3 arranged in the filter box. Wherein the sealed cavity in the main body box is used to place the mechanism that will produce air containing ultrafine particles. In this embodiment, the mechanism is an existing desktop 3D printer; the air inlet and outlet of the filter box 4 are respectively sealed and connected to the sealed cavity ; The filtering baffle 2 and the filtering baffle 3 realize the filtering function through the electrostatic spinning membrane covered thereon.

[0032] The filter box 4 is a pipeline structure, which can be similar to an inverted U-shaped stru...

Abstract

The invention discloses an ultra-fine particle filter device based on electrospinning technology, which is used for filtering air containing ultra-fine particles. Mechanism for fine-grained air; a filter box with an air inlet and an air outlet, the air inlet and outlet of the filter box are respectively sealed and connected to the sealed cavity; the filter baffle installed in the filter box, the filter baffle The plate realizes the filtering function through the electrospun membrane covered on it. The printing device of the present invention introduces the mature electrospinning technology into the filtering process of 3D printing. According to the characteristics of 3D printing itself, the electrospinning technology is organically combined with 3D printing, which can effectively remove the dust produced in the 3D printing process. Ultrafine particles, to prevent these ultrafine particles from being inhaled by the human body, and at the same time avoid their pollution to the environment.

Description

technical field [0001] The invention relates to a 3D printing device, in particular to an ultrafine particle filter device based on electrospinning technology. Background technique [0002] With the continuous development of industrial society, improving production efficiency has become a major goal of the intelligent manufacturing industry, and rapid prototyping can greatly improve the production speed. In recent years, various types of 3D printers have emerged one after another, and their application fields have also continued to expand. In addition to construction, automobiles, aerospace, medical and other fields, some offices have also begun to purchase 3D printers to improve work efficiency. [0003] At present, the main technologies of 3D printing include fused deposition rapid prototyping (FDM), stereolithography (SLA), selective laser sintering (SLS), etc., among which the most widely used method is FDM. A fused filament of material such as thermoplastic, wax or met...
