Description

Technical Field

[0001] The utility model relates to the technical field of particle screening machines, in particular to a particle screening machine for nano material production. Background Art

[0002] Nano-scale structural materials are referred to as nanomaterials. In a broad sense, they refer to ultra-fine particle materials with at least one dimension in the nanoscale range in three-dimensional space. Nanomaterials are widely used in various fields. Some nanomaterials have different properties with different particle sizes. Some nanomaterials can improve the performance of products during use if the particle size is uniform. Therefore, in some cases, it is necessary to screen the particle size of nanomaterials to obtain nanomaterials with a certain particle size range.

[0003] Existing particle screening machines for nanomaterial production mostly use vibration screening when screening nanomaterials. Although they can screen out nanomaterials well, they cannot collect the nanomaterials while screening. They need to be collected manually after screening, which reduces work efficiency and has high labor intensity for workers. Therefore, we propose a particle screening machine for nanomaterial production. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The existing particle screening machines for nanomaterial production mostly adopt vibration screening when screening nanomaterials. Although they can screen out nanomaterials well, they cannot collect the nanomaterials while screening. They need to be collected manually after the screening is completed, which reduces work efficiency and has a high labor intensity for the staff.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A particle screening machine for nano material production comprises an equipment box, on the inner side wall of which a first screening net, a second screening net and a third screening net are arranged in sequence from top to bottom, guide plates are arranged between the first screening net and the second screening net and between the second screening net and the third screening net, the backs of the first screening net, the second screening net and the third screening net are provided with collecting grooves, and the front of the equipment box is provided with storage boxes corresponding to the collecting grooves.

[0007] As a preferred solution of the utility model, a feed port is provided at the top of the equipment box, and the feed port is communicated with the interior of the equipment box.

[0008] The technical effect of adopting the above further solution is: the feed port is connected to the inside of the equipment box so that the staff can pour the material to be screened directly into the equipment box through the feed port.

[0009] As a preferred solution of the utility model, the number of meshes of the first sieve net is slightly larger than the number of meshes of the second sieve net, and the number of meshes of the second sieve net is slightly larger than the number of meshes of the third sieve net.

[0010] The technical effect of adopting the above further scheme is: the number of meshes of the first screening net is slightly larger than the number of meshes of the second screening net and the number of meshes of the second screening net is slightly larger than the number of meshes of the third screening net, so that the material to be screened can be better blown and screened while falling due to gravity, thereby enabling screening of nanomaterials.

[0011] As a preferred solution of the utility model, the collecting grooves all extend to the top of the storage box, and the storage box is a pull-out design.

[0012] The technical effect of adopting the above further solution is that the screened nanomaterials can be collected through the collecting trough and directly sent to the storage box, and the storage box with a pull-out design can more conveniently take out the collected nanomaterials.

[0013] As a preferred solution of the utility model, a mounting base is provided on the right side of the equipment box, an exhaust fan is provided on the top of the mounting base, the output end of the exhaust fan extends to the interior of the equipment box where a diversion pipe is provided, and air outlets are provided on the outer side wall of the diversion pipe corresponding to the first screening net, the second screening net and the third screening net.

[0014] The technical effect of adopting the above further scheme is: by turning on the exhaust fan, the exhaust fan can draw external air and send it into the diversion pipe, so that the air can be blown out through the air outlet and cooperate with the screening net to screen the nanomaterials.

[0015] As a preferred solution of the utility model, a controller is arranged on the front side of the equipment box near the right side.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] In the utility model, through the design of the first screening net, the second screening net, the third screening net, the collecting trough and the storage box, when the nanomaterials are screened, the exhaust fan draws in external air and blows it out through the air outlet, thereby blowing the nanomaterials, so that the nanomaterials can be screened in cooperation with the first screening net, the second screening net and the third screening net, and the nanomaterials after screening can enter the collecting trough, and the nanomaterials in the collecting trough can fall into the storage box, thereby completing the collection of the screened nanomaterials, which is more convenient and does not require manual storage.
