Description

Technical Field

[0001] The utility model relates to the technical field of silicon-manganese alloy production, in particular to an automatic feeding machine for silicon-manganese alloy production. Background Art

[0002] Silicon manganese alloy is produced by simultaneously reducing manganese oxide and silicon dioxide in manganese ore (including manganese-rich slag) and silica with carbon in a submerged arc furnace. As the temperature rises, silicon dioxide is gradually reduced to silicon by carbon, and silicon reduces Mn3C to MnSi alloy. Silicon manganese alloy with a silicon content of 23%-25% can be obtained by reducing the oxides of Mn and Si in a closed furnace.

[0003] During the feeding process, the proportion of the feed ore needs to be fed according to the production demand of silicon manganese alloy. During the feeding process, the discharge size of the feeder is fixed. During the feeding process, it is difficult to adjust the feed port according to the size of the ore, which affects the feeding efficiency. Moreover, the feeder itself is a fixed structure, and it is difficult to effectively feed multiple groups of smelting furnaces at one time. Summary of the invention

[0006] Preferably, the displacement mechanism includes a guide rod, a slide groove, an electric rod, a jacket block and an auxiliary roller, the slide groove is symmetrically distributed on the outer side of the guide rod, the electric rod is installed on one side of the guide rod, the output end of the electric rod is connected to one side of the storage box, and the jacket blocks are symmetrically distributed below the storage box, and the jacket blocks are connected to the outer side of the guide rod.

[0007] Preferably, the outer sleeve block is connected to the outer side of the slide groove through auxiliary rollers symmetrically distributed on the outer side.

[0008] Preferably, the unloading mechanism includes an inner guide box, a vertical screw, an inner tooth limit block, a unloading panel and an electromagnet bar. The inner guide box is symmetrically distributed at the inner end of the storage box. An inner tooth limit block is arranged inside the inner guide box.

[0009] Preferably, the vertical screw is connected to the inner guide box via an inner thread limit block connected to the outside.

[0010] Preferably, outer sealing strips are symmetrically distributed on the outer sides of the material unloading panel and the material storage box.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The outer sleeve blocks arranged on both sides are guided laterally by guide rods, and then the displacement spacing of the storage box is dynamically adjusted and controlled according to the number and position of the smelting furnaces under the storage box, and the moving friction of the storage box is reduced by auxiliary rollers to avoid the stability of the internal displacement of the storage box affected by excessive weight, which may cause the outer sleeve blocks and the outer side of the guide rods to get stuck.

[0023] In this embodiment, the displacement mechanism 4 includes a guide rod 2, a slide groove 3, an electric rod 5, a sleeve block 6 and an auxiliary roller 14. The slide groove 3 is symmetrically distributed on the outer side of the guide rod 2. The electric rod 5 is installed on one side of the guide rod 2. The output end of the electric rod 5 is connected to one side of the storage box 7. The sleeve blocks 6 are symmetrically distributed below the storage box 7. The sleeve blocks 6 are connected to the outer side of the guide rod 2. The equipment is guided by setting guide rods 2 of different sizes to complete the feeding process of multiple groups of smelting machines by the feeder.

[0024] In this embodiment, the outer sleeve block 6 is connected to the outer side of the slide groove 3 through auxiliary rollers 14 symmetrically distributed on the outer side. The auxiliary rollers 14 are provided to reduce the friction force during the displacement of the outer sleeve block 6.

[0025] In this embodiment, the unloading mechanism 9 includes an inner guide box 10, a vertical screw 11, an inner tooth limit block 12, a feed panel 13 and an electromagnet bar 15. The inner guide box 10 is symmetrically distributed at the inner end of the storage box 7. The inner guide box 10 is provided with an inner tooth limit block 12. The inner end of the inner tooth limit block 12 is connected to a vertical screw 11. The vertical screws 11 are equidistantly arranged on both sides of the feed panel 13. The outer sides of the electromagnet bars 15 are symmetrically distributed on both sides of the feed panel 13. The feed panel 13 is vertically guided and limited by the vertical screw 11 arranged inside the inner guide box 10.

[0026] In this embodiment, the vertical screw 11 is connected to the inner guide box 10 via an inner thread limit block 12 connected to the outside. The inner thread limit block 12 arranged on the outside of the vertical screw 11 is adjusted to adjust the vertical expansion distance of the blanking panel 13.

[0027] In this embodiment, outer sealing strips 16 are symmetrically distributed on the outer sides of the material unloading panel 13 and the material storage box 7 , and the material unloading distance is adjusted and controlled through the material unloading panel 13 .

[0028] The actual application of this automatic feeding machine for silicon manganese alloy production includes the following work contents:

[0029] Step 1: The operator first connects the inner tooth limit block 12 with the vertical screw 11 according to the size and type of the ore, and then adjusts the position of the inner tooth limit block 12. According to the requirements of material cutting, the position of the inner tooth limit block 12 is rotated outside the vertical screw 11, and then the descending position of the inner tooth limit block 12 is adjusted. The inner tooth limit block 12 and the vertical screw 11 are installed inside the inner guide box 10 on the left and right sides to guide the descending direction of the material cutting panel 13.

[0030] Step 2: The operator opens the electromagnet bar 15, and uses the electromagnet bar 15 to magnetically attract the bottom of the unloading panel 13 and the storage box 7, and uses the outer sealing strip 16 arranged on the outside to block the gap between the unloading panel 13 and the storage box 7. The operator guides the ore into the inside of the feed through hole 8 through the conveyor belt, and stores the ore through the storage box 7;

[0031] Step 3: The operator can open the electric rod 5 and push one side of the material storage box 7 through the electric rod 5. The material storage box 7 slides on the outside of the guide rod 2 through the outer sleeve block 6 arranged below. The auxiliary roller 14 arranged on the outside of the outer sleeve block 6 slides on the outside of the chute 3 opened on the outside of the guide rod 2, thereby adjusting the position of the material storage box 7, and then aligning the bottom of the material storage box 7 with the top of the smelting furnace;

[0032] Step 4: The operator turns off the electromagnet bar 15, thereby separating the unloading panel 13 from the bottom end of the storage box 7, and then moves the vertical screw 11 vertically downward, thereby moving the unloading panel 13 vertically downward, so that the ore is discharged downward from both sides of the unloading panel 13, and the descending range of the vertical screw 11 is controlled by the inner tooth limit block 12, and the inner tooth limit block 12 is moved inside the inner guide box 10 to prevent the vertical screw 11 from descending too large a range and affecting the unloading speed.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
