Description

 The invention relates to the separation and sorting of solid bulk materials and can be used in the processing industry for radiometric separators.

 Known ore sorting installation, including a hopper, vibratory feeders, ore preparation blocks, a conveying device and an actuator, for example an electro-pneumatic valve / USSR Author's Certificate N 1690845, class. B 03 B 7/00, 1989 /.

 The known installation is not efficient enough and reliable in operation upon receipt of the sortable material with a high concentration of the useful component due to the forced continuous and intensive operation of the actuator; the installation does not provide high quality separation and simultaneous separation of the sorted material into three components.

 Closest to the claimed is a device for sorting bulk material used in the method of sorting the latter and comprising a conveyor with sensors connected by an electronic control system, a nozzle with a camera directed across the flow of pieces of material, and supplying compressed air to the chamber tubes / USSR Copyright Certificate N 697192 , cl. B 03 B 13/06, 1977 / - prototype.

 The known device is not reliable in operation during a long high-frequency response mode, is not economical in the expenditure of the working fluid (water, compressed air), does not provide the necessary quality of separation.

 The problem solved by the invention is to increase the reliability of the sorting device at various operating modes, improve the quality of separation and expand the functionality of the device by sorting into three components.

 The problem is solved in that in the sorting device of the radiometric separator, which includes a feed mechanism for the sortable material, a radiation recording unit associated with an electronic control system, an actuating unit for changing the trajectory of the sortable material, the latter according to the invention is made in the form of two deflecting mechanisms arranged vertically in series at different heights, while one of the deflecting mechanisms represents a baffle gate, and the other a nozzle with the possibility of pulse mildew liquid or gas. In addition, the fender gate is installed below the nozzle level.

Comparative analysis with the prototype shows that the claimed solution is characterized in that:
- the node changes the trajectory of the sorted material is made in the form of two deflecting mechanisms, sequentially located at different heights;
- one of the mechanisms is a fender gate, and the other is a nozzle with the possibility of pulsed ejection of liquid or gas;
- the gate is installed below the nozzle level.

 Thus, the claimed solution meets the criterion of "novelty."

 Comparison of the proposed solutions with the analogue did not allow him to identify signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "inventive step".

 The invention is illustrated in the drawing. It shows a sorting device 1 in section, side view.

 The radiometric separator screening device comprises a feed mechanism for the material to be sorted 1, a radiation registration unit 2, an actuating unit 3, a nozzle 4, a breaker gate 5.

 Sorting device operates as follows.

 Sorted material from the feeding mechanism 1 is sent to the area of the radiation registration unit 2, where the signal from the sorted material is registered and an electronic control unit receives a command to the actuating unit 3 to trigger one of the actuators deflecting the path of movement - nozzle 4 or jack gate 5. When nozzle 4 is periodically triggered by supplying a material that is poor in content of the useful component of the material, and when a material rich in content is fed, the command is sent to the gate gate 5 with installation of the latter in the working position for constant rebound of the sorted material without the energy consumption of the nozzle 4. When sorting the material into three components, the breaker gate 5 operates in the "empty rock - rich rock" mode, and the nozzle 4 beats the third component from the sorted material.

 The radiometric separator sorting device allows to increase the reliability and quality of separation by separation of functions between high-speed and "slowly" operating actuators, reduce energy consumption, and if necessary, separate the material into three component components.
