[0002] The screening and collecting equipment for petroleum fracturing experiment proppants mainly screens various proppants of different sizes by means of vibration screening, and during the screening process, each size of proppants will be centrally collected to facilitate the one-time treatment of the screened proppants. During the vibration screening process, the qualified proppants will pass through the sieve mesh, while the unqualified proppants will be blocked by the sieve mesh, thus achieving the screening purpose.

[0003] After retrieval, the application number "202322402852.0" discloses a screening and collecting device for petroleum fracturing experiment proppants, including an installation bottom frame and metal columns respectively fixed at the top near the four corners of the installation bottom frame by welding, and vibration springs are fixed at the top ends of the four metal columns by bolts. By adding a new replaceable collecting device under the discharge hopper of this screening and collecting device for petroleum fracturing experiment proppants, and the replaceable collecting device is fixed at the right end of the installation bottom frame by two installation bottom frames. When the proppants are discharged through the discharge hopper after being vibrated and screened, the replaceable collecting device can centrally collect the support frames through a replaceable collecting box. After the replaceable collecting box inside is filled with proppants, an adjacent replaceable collecting box can be pushed in the large-area storage box to replace the replaceable collecting box filled with proppants until a new replaceable collecting box replaces the replaceable collecting box filled with proppants for material collection.

The electromagnets 9 are connected to the servo motor 6 through a circuit in the same path. When the servo motor 6 is started, the electromagnet 9 on the right side is controlled to be turned off.

[0036] The first conveyor belt 7 is fixedly connected to the middle position on the right side of the two rotating disks 5. The conveying direction of the first conveyor belt 7 is away from the rotating disk 5. The second conveyor belt 8 is arranged at the bottom position of the inner walls of the two rotating disks 5. A baffle 14 for limiting is fixedly connected to one end of the second conveyor belt 8 located inside the rotating disk 5.

When the electromagnet 9 rotates to the position of the collection box 12, the electromagnet 9 starts to attract the fixed block 20, driving the collection box 12 to lift. When the collection box 12 moves to the top, the raw materials sieved by the vibrating screen 1 are fed through the discharge port 3 and can fall into the partition 13 on the collection box 12, squeezing the partition 13. When the partition 13 is squeezed, it can drive the reset spring 16 to stretch. When the set threshold is reached, the limit slider 17 can move downward to squeeze the trigger switch 18. When the trigger switch 18 is squeezed, it can be transmitted to the servo motor 6 through a wireless signal. The servo motor 6 can drive the rotating disk 5 to rotate to the top of the first conveyor belt 7 on the right side. At this time, the electromagnet 9 is turned off, and the collection box 12 can fall to the first conveyor belt 7 for feeding.
