Technical Field

The invention relates to a waste alcohol filtering and recycling device for 3D printing of photosensitive resin, and belongs to the technical field of 3D printing equipment.

Background

3D printing (3DP), one of the rapid prototyping technologies, is a technology that constructs an object by printing layer by layer using an adhesive material such as powdered metal or plastic based on a digital model file.

3D printing is typically achieved using digital technology material printers. The method is often used for manufacturing models in the fields of mold manufacturing, industrial design and the like, and is gradually used for directly manufacturing some products, and parts printed by the technology are already available. The technology has applications in jewelry, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.

Need use alcohol recovery unit in the current 3D printer, current alcohol recovery unit needs the heating, and alcohol is inflammable, has the potential safety hazard, needs the consumption electric energy simultaneously, and use cost is high, and recovery efficiency is low.

Disclosure of Invention

In view of the above disadvantages of the prior art, an object of the present invention is to provide a filtering and recycling device for waste alcohol for 3D printing of photosensitive resin, which is used to solve the problems in the prior art that the existing alcohol recycling device needs to be heated, and alcohol is inflammable, so that there is a potential safety hazard, and at the same time, electric energy needs to be consumed, so that the use cost is high, and the recycling efficiency is low.

In order to achieve the above and other related objects, the present invention provides a filtering and recycling apparatus for waste alcohol used in 3D printing of photosensitive resin, comprising: filter housing and alcohol recycling bin, filter housing top be provided with the top cap, the inside primary filter that is provided with of filter housing, the primary filter below is provided with secondary filter, the secondary filter below is provided with tertiary filter, alcohol recycling bin set up in filter housing below, be connected with filter housing.

In an embodiment of the invention, a valve is disposed at a connection position of the alcohol recovery tank and the filter housing.

In an embodiment of the present invention, the primary filter is made of a dense gauze.

In an embodiment of the present invention, the secondary filter is made of cotton cloth.

In one embodiment of the present invention, the third filter is made of pp cotton.

As described above, the filtering and recycling device for waste alcohol for 3D printing of photosensitive resin of the present invention has the following beneficial effects:

compared with the existing alcohol recovery device, the alcohol recovery device provided by the invention has the advantages that heating is not needed, potential safety hazards are reduced, auxiliary energy is not needed, only a plurality of groups of filtering devices are needed, the use cost is lower, the structure is simple, the manufacturing cost is low, and the alcohol recovery efficiency is high.
