Coal and gangue sorting device and system

Abstract

The invention provides a coal and gangue sorting device and system, and relates to the technical field of coal and gangue sorting. The coal and gangue sorting device comprises an auxiliary device, a recognition processing device, a control device and an executing mechanism. The auxiliary device is used for heating an object to be detected in a heat convection mode so as to stimulate the thermal radiation characteristic on the surface of the object to be detected. The recognition processing device is connected with the auxiliary device and is used for processing the thermal radiation characteristic to obtain a first temperature domain image and sending the first temperature domain image to the control device. The control device is connected with the recognition processing device and is used for processing the first temperature domain image to obtain picking coordinates of the object to be detected and sending pulse signals to the executing mechanism according to the picking coordinates. The executing mechanism is connected with the control device and is used for executing corresponding operations according to the pulse signals so as to separate the object to be detected. By the adoption of the infrared thermal imaging sorting mode, on the basis of no radiation effect, errors are small and the sorting index is high.

Description

technical field [0001] The invention relates to the technical field of coal and gangue separation, in particular to a coal and gangue separation device and system. Background technique [0002] Gamma rays have a very strong penetrating ability. When the human body is irradiated by gamma rays, the gamma rays will enter the interior of the human body and ionize with the cells in the body. The ions generated by the ionization can erode complex organic molecules, such as Proteins, nucleic acids, enzymes, etc. At the same time, the above-mentioned organic molecules are the main components of living cell tissues. Once they are destroyed, the normal chemical processes in the human body will be disturbed, and more seriously, cell death will occur. As mentioned above, gamma rays are seriously harmful to the human body. [0003] The existing automatic coal and gangue sorting methods mostly use gamma rays for identification, and high-frequency air valves are used to shoot down the ide...

Problems solved by technology

[0002] Gamma rays have extremely strong penetrating power. When the human body is irradiated by gamma rays, the gamma rays will enter the interior of the human body and interact with cells in the body Ionization, the ions produced by ionization can corrode complex organic molecules, such as proteins, nucleic acids, enzymes, etc. At the same time, the above-mentioned organic molecules are the main components of living cell tissues, once they are destroyed, it will lead to damage in the human body. The normal chemical process is disturbed, and more serious cell death will occur. In summary, gamma rays are seriously harmful to the human body

[0003]The existing automatic coal and gangue sorting methods mostly use gamma rays for identification, and use high-frequency air valves to shoot down the identified coal or gangue for sorting , while using the high-frequency air valve to shoot down the identified coal or gangue, the error rate is large and the sorting rate is relatively low
