Description

Technical Field

[0001] The invention relates to the technical field of diamond screening, in particular to a magnetostrictive diamond screening machine. Background Art

[0002] Artificial diamonds are produced by equipment such as six-sided top presses under high temperature and high pressure conditions using raw materials such as graphite. They are widely used in various process industries. The diamonds produced are in various shapes such as round, square, hexagonal and irregular, so a screening machine is needed to screen the diamonds and determine the grade of the diamonds. Currently, the commonly used diamond screening machines are mainly screened by vibrating screens. The vibrating screens are mainly composed of a screen frame and an oscillating motor. The screen frame is driven by the oscillating motor to continuously vibrate. At this time, the diamonds on the surface of the screen frame will roll down and be screened. Because round diamonds roll faster and non-round diamonds roll slower, they are easier to pass through the sieve holes. This principle is used to screen out round diamonds. In the actual screening process, the applicant found that this commonly used diamond screening machine has the following shortcomings:

[0003] 1. Using an oscillating motor to drive vibration produces loud noise during the vibration process, and consumes high energy, which is not energy-saving and environmentally friendly;

[0004] 2. The initial speed of the falling diamond is slow, and the round diamonds can be easily screened out through the sieve holes. The irregularly piled diamonds contain more round diamonds, and the screening effect is poor. Summary of the invention

[0008] Preferably, a control panel is fixedly mounted on the front of the distribution box, an on / off switch is fixedly mounted on the surface of the control panel, and the magnetostrictive oscillator is electrically connected to an external power supply via the on / off switch, so the operation is simple and convenient.

[0009] Preferably, the gap between two adjacent accelerating guide rods increases from left to right, which is beneficial to accelerate and guide the newly added diamond particles and improve the screening effect.

[0010] Preferably, the support frame assembly includes a support column and a screen vibration spring fixedly arranged on the top of the support column, and a welding frame is fixedly arranged on the top of the screen vibration spring.

An accelerating rod structure with increasing gap is added to the lower screen frame, so that the diamonds just added to the screening machine will not fall down immediately due to the small gap of the accelerating rod, but will roll and accelerate.

DETAILED DESCRIPTION

A round particle discharge chute 8 and an irregular discharge chute 9 are fixedly arranged at one end of the screening frame 1 away from the upper hopper 2. A distribution box 6 is fixedly installed on the front of one of the supporting base frame components 5, and a control panel 7 is fixedly installed on the front of the distribution box 6. An on-off switch is fixedly installed on the surface of the control panel 7, and the magnetostrictive oscillator 3 is electrically connected to the external power supply through the on-off switch.

[0026] When in use, a magnetostrictive oscillator 3 is used to replace the traditional oscillation motor drive, and the magnetostrictive principle is relied upon to realize the oscillation screening of the screening machine, so that there is no motor vibration sound during the diamond screening process, the noise is smaller, and the energy consumption is lower, which is more energy-saving and environmentally friendly.

[0027] See also Figure 1 , Figure 5 and Figure 6 Furthermore, the round particle discharge chute 8 is arranged opposite to the lower screen frame 12, and the irregular discharge chute 9 is arranged opposite to the bottom wall of the screening frame 1; the gap between two adjacent acceleration guide rods 13 increases from left to right;

[0028] When in use, the diamonds just added to the screening machine will not fall down immediately due to the small gap between the two adjacent acceleration rods 13, but will roll and accelerate forward. When the gap between the two adjacent acceleration rods 13 becomes larger, the accelerated diamond particles will fall into the lower screen frame 12 again. Since the round diamonds roll very fast after acceleration, it is difficult for them to pass through the screen holes 14, but they will directly roll out along the lower screen frame 12 and enter the round particle feeding chute 8 for direct discharge. The irregular diamond particles are not smooth and roll slowly. During the oscillation process, they are screened through the screen holes 14, fall into the bottom wall of the screening frame 1, and finally enter the irregular feeding chute 9 for discharge, thereby realizing the screening of diamonds.

The screening process will not affect the vibration of the screening frame 1, the vibration is smooth and stable, and the screening is efficient.

[0031] See also Figure 1 Further, a cleaning port 18 is provided in the middle of both sides of the screening frame 1, an inspection door 10 is hinged on the cleaning port 18, a card seat 17 is fixedly provided on the outer side of the inspection door 10, and a card rod 16 is rotatably connected to one side of the cleaning port 18, and the card rod 16 is arranged opposite to the card seat 17;

At this time, the clamping seat 17 can be pinched and pulled outward, and the inspection door 10 can be opened. The diamond particles stuck in the sieve hole 14 can be cleaned through the cleaning port 18. The cleaning and maintenance are simple and efficient.

[0033] When the embodiment of the present application is used: the device is started, and at this time, driven by the magnetostrictive oscillator 3, the screening frame 1 will continue to vibrate and screen, and the magnetostrictive oscillator 3 is used to replace the traditional oscillation motor drive, and the oscillation screening is realized by relying on the magnetostrictive principle, so that there is no motor whistling sound during the diamond screening process, the noise is smaller, and the energy consumption is lower, which is more energy-saving and environmentally friendly;

[0034] After the screening frame 1 vibrates stably, the diamond particles to be screened can be added through the upper hopper 2, and the added diamond particles will fall on the accelerating guide rod 13. The diamonds just added to the screening machine will not fall immediately due to the small gap between the two adjacent accelerating guide rods 13, but will roll and accelerate forward. When the gap between the two adjacent accelerating guide rods 13 becomes larger, the accelerated diamond particles will fall into the lower screen frame 12 again. Since the round diamonds roll very fast after acceleration, it is difficult to pass through the sieve hole 14, but directly roll out along the lower screen frame 12, enter the round particle feeding chute 8, and be directly discharged. The irregular diamond particles are not smooth and roll slowly. During the vibration process, they are screened through the sieve hole 14, fall into the bottom wall of the screening frame 1, and finally enter the irregular feeding chute 9 for discharge, thereby realizing the screening of diamonds, and the overall screening effect is more significant.
