Problems solved by technology

[0003] Existing screening equipment includes linear screens, vibrating screens, drum screens (such as CN200977504Y), etc., which can partially achieve size separation, but cannot fully meet the purpose of this process, such as failing to meet the requirements of fine screening and continuous and uniform feeding , The contact distance between the material and the screen is not enough, so it is easy to miss the screen, the screen is easy to block, resulting in low screening efficiency, easy to cause particle extrusion and rupture, and inconvenient loading and unloading (every batch of nuclear fuel screening needs to clean the drum screen to prevent nuclear fuel contamination and cross-contamination ), etc., so this patent designs a set of drum-type particle size sorting device, which can meet the requirements of fine screening, continuous and uniform feeding, large contact distance between materials and screens, and no leakage of screens. suitable for industrial applications

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Such as Figure 1~2 As shown, the drum-type particle sorting device provided by the embodiment of the present invention includes a frame, a feeding bin 2, a feeding trough 3, a vibrating feeder 4, a drum screen cage 6, a rolling brush 14, a variable speed motor, a container, Chassis 7, controller 1.

[0031] The feeding bin 2 is used to hold the particles to be screened, and adopts a reasonable geometric design, which is in the shape of an inverted rectangular prism, which is convenient for particle movement, and is equipped with a transparent cover that is easy to open and clean.

[0032] The feeding trough 3 is a particle feeding buffer zone, and an adjustable v...

Abstract

The invention discloses a drum-type particle sorting device which is characterized by comprising a frame, a feeding bin, a particle groove, a feeding device, drum screen cages, rolling fur brushes, a speed change motor, a container, a chassis and a control device. According to the particle sorting device, damage to particles is small, sorting parameters can change within a large range, precise selection of particle sizes can be efficiently achieved, continuous even feeding of the particles can be achieved, screening missing and screen blocking can not happen, disassembly and assembly are convenient, and cleaning is easy.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a drum-type particle sorting device. Background technique [0002] The ceramic fuel element used in my country's pebble bed high-temperature gas-cooled reactor has a structure of spherical coated particles (TRISO) dispersed in the graphite matrix of the fuel zone. The first guarantee of the inherent safety of the high-temperature gas-cooled reactor nuclear power plant is that the nuclear fuel used is TRISO-type coated particles, which consists of a nuclear fuel core, a loose pyrolytic carbon layer, an inner dense pyrolytic carbon layer, a silicon carbide layer and an outer layer. Dense pyrolytic carbon layer composition. Coated fuel particles are an important part of spherical fuel elements in high temperature gas-cooled reactors. Coated fuel particles can effectively block the release of fission products, thus ensuring the excellent safety of high-temperature ...
