[0002] Silicon powder is used in the casting process of instrument transformers. It can enhance mechanical properties and improve electrical properties. In current production practice, according to the production process, silicon powder is quantitatively added to the resin and / or curing agent raw materials.

[0003] Therefore, the production process involves the transfer, conveying and addition of silicon micropowder. Traditional transfer, conveying and addition methods are mostly manual, which is time-consuming and labor-intensive due to the high pouring platform. After technical transformation, positive pressure conveying is adopted, but this causes inconvenience to degassing in subsequent processes and affects product quality.

[0004] Therefore, this utility model proposes a silicon micro powder silo device for casting current transformers. In the process, silicon micro powder is transferred from the raw material stacking area to the silo, and then further transported to the downstream end through vacuum conveying in the silo. The process is more stable and efficient, bringing convenience to actual production. Utility Model Content

A vibration motor 21 is installed above the bottom outlet of the silo 2. The bottom outlet of the silo 2 is connected to the suction adapter 22, and the suction adapter 22 is connected to the silicon micro powder conveying pipeline.

[0029] In this embodiment, the silo device also includes a gantry frame 3, through which a traveling rail 4 is fixedly connected. A suspended traveling trolley 5 is installed on the traveling rail 4, and the suspended traveling trolley 5 cooperates with the ton bag frame 6. In this embodiment, the traveling rail 4 is arranged from the raw material stacking area to above the silo 2.

[0030] In this embodiment, the ton bag frame 6 includes four booms 61, which are respectively engaged with four straps of the ton bag via hooks 64. The four booms 61 are arranged in a cross shape. A lifting ring 62 is provided above the center of the ton bag frame 6, which is engaged with the suspended trolley 5. A limiting device 63 is provided at the front end of each boom 61, which is engaged with the hook 64.

[0031] In this embodiment, a limiting groove 611 is provided at the front end of each boom 61, and the limiting groove 611 cooperates with the connecting ring above the hook 64; the limiting device 63 includes a first mounting plate 631, a second mounting plate 632 and a third mounting plate 633, the first mounting plate 631 is located at the front end of the boom 61, and the limiting groove 611 is located between the first mounting plate 631 and the second mounting plate 632; a through hole is provided on the second mounting plate 632, and a telescopic rod 635 is slidably inserted through the through hole; the telescopic rod 635 is hollow, and a through square fitting hole is provided in the telescopic rod 635, and the guide rod 634 is square, which slides with the square fitting hole and restricts the telescopic rod 635. The guide rod 634 rotates 35, and the front end of the guide rod 634 does not separate from the telescopic rod 635 during the movement of the telescopic rod 635; the other end of the guide rod 634 is fixedly connected to the third mounting plate 633, a spring 636 is sleeved on the guide rod 634, and a mating part 6351 is provided at the end of the telescopic rod 635, the spring 636 and the mating part 6351 cooperate; a hand-held part 6352 is provided upward on the telescopic rod 635 between the first mounting plate 631 and the second mounting plate 632, and a limiting part 6353 is provided downward. When the front end of the telescopic rod 635 abuts against the first mounting plate 631, the limiting part 6353 is located on the side of the limiting groove 611 near the second mounting plate 632.

[0032] The principle of this utility model is as follows:

[0033] In use, the ton bag rack 6 is held by the hook of the suspended trolley 5. The controller of the suspended trolley 5 controls the trolley 5 to run on the trolley track 4. The suspended trolley 5 is moved to the raw material stacking area. In the raw material stacking area, the four hooks 64 of the ton bag rack 6 are connected to the straps of the ton bag. Then the ton bag is lifted and transferred to the top of the silo. At this time, the ton bag is opened (cut open) and the silicon powder in the ton bag is transferred to the silo. At this time, negative pressure is applied to the silicon powder conveying pipeline (the negative pressure fan is connected to the upper end of the tank at the end of the silicon powder conveying pipeline). By adjusting the appropriate air volume through the suction adapter 22, the silicon powder can be continuously and stably conveyed to the rear end.

[0034] This utility model involves a vibration motor 21, a material suction adapter 22, and a suspended crane 5, etc. Since these are existing and mature devices, no improvements have been made to them in this utility model, so they will not be described in detail.

[0035] In the use of this utility model, since the hook 64 in the ton bag frame 6 is locked within a certain range, the hook 64 can be effectively prevented from falling off due to the swing of the ton bag frame 6 during the operation of the overhead crane 5, making it more convenient and stable to use.

[0036] For the installation of the limiting device 63, the second mounting plate 632 with a through hole can be installed first. The rear end of the telescopic rod 635 (the handle part 6352 on the front side of the telescopic rod 635 and the limiting part 6353 are pre-welded and fixed) passes through the through hole from front to back, with the through hole fitting the telescopic rod 635. Then, the mating part 6351 is welded to the rear end of the telescopic rod 635. At this point, the guide rod 634 is connected and fixed to the third mounting plate 633. The spring 636 is sleeved on the guide rod 634, and the front end of the guide rod 634 is inserted into the telescopic rod 635, pushing the third... The mounting plate 633 is pushed until the spring 636 contacts the mating part 6351 and continues to push, so that the mating part 6351 contacts the second mounting plate 632 under the action of the spring 636. At this time, the spring 636 is in a compressed state and welds the second mounting plate 632 to fix it (at this time, the front end of the guide rod 634 extends slightly beyond the second mounting plate 632 to prevent the telescopic rod 635 from separating from the guide rod 634 during the movement). Then, the first mounting plate 631 is welded to fix it (the connecting ring of the hook 64 is slightly larger to avoid the situation where it cannot be installed).
