The first collecting box 501 is arranged below the conveying belt 3102.

[0047] The magnetic screen driver 3101 is electrically connected with the main control system 60, and the output end of the magnetic screen driver 3101 is drivingly connected with the strong magnetic roller 31030 at the front end of the conveying belt 3102.

[0048] Therefore, according to the arrangement mode of the strong magnetic roller 31030, the weak magnetic roller 31031 and the conveying belt 3102, when the powder material crushed by the crushing roller group 212 falls on the conveying belt 3102, the strong magnetic roller 31030 arranged at the front end of the conveying belt 3102 adsorbs the magnetic metal particles through strong magnetic action, so as to avoid the magnetic metal particles from falling from the front end of the conveying belt 3102 to the first collecting box 501; the strong magnetic roller 31030 arranged at the rear end of the conveying belt 3102 prevents the magnetic metal particles from being thrown out from the rear end of the conveying belt 3102 under the action of the rotational inertia of the conveying belt 3102, so as to cause dust pollution; in addition, the weak magnetic roller 31031 is arranged at the middle of the conveying belt 3102, so that the magnetic metal particles accumulated to a certain amount at the middle of the conveying belt 3102 fall into the first collecting box 501 under the action of gravity, thereby completing the automatic magnetic classification and recovery of the magnetic metal particles; in addition, the non-magnetic metal particles and the diamond particles fall from the rear end of the conveying belt 3102 and are blown to the non-magnetic processing cavity 41 without being affected by the magnetic action.

[0049] The blowing system 330 has a high-pressure gas tank 3301, a conveying pipe 3302 and a blowing nozzle 3303. The high-pressure gas tank 3301 is connected with one end of the conveying pipe 3302 and communicates with the non-magnetic processing cavity 41 through the conveying pipe 3302. The conveying pipe 3302 is connected with the non-magnetic processing cavity 41 and the blowing nozzle 3303 is arranged at the connecting end of the conveying pipe 3302 and the non-magnetic processing cavity 41. A non-magnetic hopper 40 is arranged below the rear end of the conveying belt 3102. The non-magnetic hopper 40 can collect the non-magnetic metal particles and diamond particles falling from the rear end of the conveying belt 3102. The discharge port of the non-magnetic hopper 40 communicates with the conveying pipe 3302, so that the non-magnetic metal particles and diamond particles in the non-magnetic hopper 40 fall into the conveying pipe 3302 through the discharge port.

[0050] The high-pressure gas tank 3301 is provided with a high-pressure gas valve 3304 which is electrically connected with the main control system 60. Therefore, the high-pressure gas valve 3304 is controlled to open and release the high-pressure gas in the high-pressure gas tank 3301 by sending a command through the main control system 60. A negative pressure area is formed at the connecting position of the conveying pipe 3302 and the non-magnetic hopper 40, so as to drive the non-magnetic metal particles and diamond particles in the conveying pipe 3302 to be sprayed from the blowing nozzle 3303 into the non-magnetic processing cavity 41.

[0051] The adsorption system 320 has a negative pressure generator 321 and a negative pressure pipe 322. The negative pressure pipe 322 is provided with an adsorption cover 323 at one end and communicates with the top of the non-magnetic processing cavity 41 through the adsorption cover 323.

Under the control of the main control system 60, the negative pressure generator 321 is started to generate a negative pressure environment in the negative pressure pipe 322.

[0052] The non-magnetic metal particles and diamond particles entering the non-magnetic processing cavity 41 through the high-pressure gas are mixed with the high-pressure gas to form a mist. According to the self-weight of the non-magnetic metal particles and diamond particles, the non-magnetic metal particles float upward in the non-magnetic processing cavity 41, and the diamond particles sink downward, so that the non-magnetic metal particles and diamond particles are layered.

[0053] Therefore, the upward floating non-magnetic metal particles can be collected into the second collecting box 502 through the negative pressure cover and the negative pressure suction in the negative pressure pipe 322, thereby realizing automatic adsorption and collection of the non-magnetic metal particles. The remaining diamond particles with heavier mass sink to the lower layer.

[0054] The non-magnetic processing cavity 41 is provided with a discharge port on the lower side of the end opposite to the blowing nozzle 3303, and the third collecting box 503 is arranged below the discharge port of the non-magnetic processing cavity 41. The high-pressure gas is sprayed through the blowing nozzle 3303, and the diamond particles sink under the action of the gravity of the combined diamond particles, so that the diamond particles fall through the discharge port of the non-magnetic processing cavity 41 to the third collecting box 503, thereby completing the automatic air-blowing classification and collection of the diamond particles. In addition, the bottom of the non-magnetic processing cavity 41 is gradually inclined to the discharge port, and the bottom of the non-magnetic processing cavity 41 is inclined, which is beneficial to the discharge of the diamond particles in the non-magnetic processing cavity 41 to the third collecting box 503 through the discharge port, and the diamond particles are discharged more completely and cleanly.

[0055] The third collecting box 503 is provided with a plurality of detection modules 61, and the detection modules 61 can selectively use alloy detection probes and are electrically connected with the main control system 60.

[0056] Under the control of the main control system 60, the detection modules 61 detect the metal content of the diamond particles falling from the non-magnetic processing cavity 41 to the third collecting box 503 in real time, thereby obtaining a detection signal of the related metal content, and then the detection modules 61 feed the detection signal of the metal content to the main control system 60. After processing, the main control system 60 sends the detection signal to the data processing module 62, which calculates and analyzes the specific metal content data, and the main control system 60 also transmits the specific metal content data to the display module 63, which displays the metal content of the current diamond particles in real time, so that the staff can understand the screening situation of the diamond particles in real time and intuitively.

[0057] If the data calculated and analyzed by the data processing module 62 is less than the set value, the main control system 60 judges that the diamond particles are qualified for recycling; if the data calculated and analyzed by the data processing module 62 is greater than the set value, the main control system 60 controls the adsorption system 320 to adjust the adsorption force and the blowing system 330 to adjust the gas flow, so that the metal content of the diamond particles is adjusted to be within the qualified range.

[0058] The detection principle of the detection module 61 in the embodiment is that when the detection module 61 passes through an alternating current, an alternating magnetic field is generated, and if there is a metal object in the alternating magnetic field, the metal object generates an eddy current, and the eddy current generates a new magnetic field, which affects the distribution of the original magnetic field, thereby feeding back the metal content.

[0059] Therefore, by setting the detection module 61 on the third collection box 503, the detection signal of the metal content of the current diamond particles is obtained in real time, and by the data processing module 62, the specific calculation and analysis result is obtained by accurately calculating and analyzing the detection signal, and the main control system is judged, so that the purpose of real-time detection and judgment of whether the metal content of the current diamond particles is qualified is realized, and the recovery quality of the diamond particles is improved while the diamond particles are automatically recovered.

[0060] In the embodiment of the application, when the metal particle content in the total recovered diamond particles of the third collection box 503 is less than 10% within one hour, it is judged that the diamond particle recovery is qualified.

[0061] In this way, the embodiment of the application sets the crushing system 21 on the crushing station 20 to automatically crush the grinding wheel cutter head to obtain powder material, which is more convenient and efficient than the previous manual knocking and recovery; by setting the first screening mechanism 31, the second screening mechanism 32 and the third screening mechanism 33 in turn along the powder material screening process direction according to the recovery requirements on the screening station 30, and correspondingly setting the magnetic screen system 310, the adsorption system 320 and the blowing system 330, under the control of the main control system 60, the magnetic screen system 310 is used to screen the magnetic metal particles from the powder material, the adsorption system 320 is used to screen the non-magnetic metal particles from the powder material, and the blowing system 330 is used to screen the diamond particles from the powder material, and then fall into the corresponding collection box of the collection station 50, thereby realizing the automatic classification and recovery of the powder material; compared with the previous cutter head recovery equipment, the embodiment of the application can further screen the non-magnetic metal particles from the diamond particles in the mixed powder material, and the recovery precision, quality and efficiency are further improved, the screening purity of the diamond particles is improved, and the high-frequency heating process is not required, which is more energy-saving.

[0062] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-substantial changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection required by the present application.
