Description

Technical Field

[0001] The invention relates to the technical field of metal roughing, and in particular to a column-type short-process tungsten roughing process and equipment. Background Art

[0002] my country is extremely rich in tungsten resources, and its tungsten reserves and mining scale rank first in the world. At present, more than 20 kinds of tungsten minerals have been discovered, among which wolframite and scheelite have the greatest industrial value. They are often accompanied by a variety of useful minerals such as bismuthite, galvanneite, pyrite, pyrrhotite, cassiterite, etc., and gangue minerals are usually fluorite, garnet, calcite, quartz, feldspar, etc. Tungsten minerals are usually closely symbiotic with other minerals, with fine and uneven embedding. In addition, the floatability of various gangue minerals and tungsten minerals is similar, while the floatability of black and white tungsten is quite different, and the corresponding flotation conditions are different. Therefore, it is difficult to determine the reasonable grinding fineness and separation process to obtain various ideal products, which makes the beneficiation of tungsten minerals in my country difficult.

[0003] The existing column-type short-process tungsten roughing equipment needs to manually add additives to the raw ore when preparing flotation feed. This process will cause the equipment to be shut down and wait. The inability to automatically add additives will extend the roughing process time of the equipment and reduce the roughing efficiency of the equipment. Summary of the invention

There are two symmetrical movable blocks 622, and the upper sides of the two movable blocks 622 are rotatably connected to push rods 623 through bearings.

The outsides of the two movable blocks 622 are connected to two connecting plates 625 through bolts, and the opposite sides of the two connecting plates 625 on the same side are connected to springs 626 through bolts.

[0035] Specifically, after the tungsten ore and additives in the mixing barrel 9 are stirred to form a roughing feed, the discharge pipe 10 draws the roughing feed in the mixing barrel 9 out of the barrel body 1, and the weight of the mixing barrel 9 is reduced, so that the spring 2 626 pulls the movable block 622 in the rectangular groove 621 toward the center, so that the mixing barrel 9 is gradually raised under the push of the push rod 623, and the top block 618 on the raised mixing barrel 9 contacts the connecting rod 619 and pushes the connecting rod 619 to move upward on the vertical groove 616, so that the rack 6 connected to the connecting rod 619 is raised. 20 meshes with the outer tooth ring 615 and rotates, so that the rotating cylinder 605 on the containing box 602 drives the rotating member 609 to connect the bevel groove 613 with the discharge port 606, so that the additive in the containing box 602 can be transported into the mixing barrel 9 through the conveying pipe 607 to mix with the tungsten ore. After a certain amount of additive is added, the increased weight causes the mixing barrel 9 to drop again, so that the rack 620 drives the outer tooth ring 615 to rotate, so that the rotating cylinder 605 closes the discharge port 606 and the channel between the discharge port 606, so that the additive no longer flows into the mixing barrel 9.

[0036] In a specific application scenario, the quantitative addition module 6 is mainly suitable for the quantitative addition link in the quantitative addition process, that is, the quantitative addition module 6 uses the rotating part 609 and the rotating cylinder 605 to enable the device to automatically deliver a quantitative amount of additives according to the amount of tungsten ore added after adding a quantitative amount of tungsten ore. While ensuring the continuity of the process, it reduces the excessive addition of additives, reduces the waste of resources, and improves economic benefits.

[0040] Reference Figure 7In a preferred embodiment, the uniform stirring module 8 includes a main shaft 801, a hole groove is opened on the upper side of the top cover 2, the inner wall of the hole groove is rotatably connected to the outside of the main shaft 801 through a bearing, the outside of the main shaft 801 is connected with four mutually symmetrical cross bars 802 through bolts, and the two cross bars 802 on the same side are rotatably connected with the same secondary shaft 803 through bearings, and the outside of the secondary shaft 803 is connected with gears 804 through bolts, and the gears 804 are all located on the upper side of the cross bar 802, and the bottom of the top cover 2 is connected with three circumferentially equidistant positioning plates 805 through bolts; the three positioning plates The bottom of 805 is bolted to the same inner gear ring 806, the two gears 804 are meshed with the inner gear ring 806, and the outside of the two secondary shafts 803 are bolted to two symmetrical cross bars 807; the opposite sides of the two cross bars 807 on the same secondary shaft 803 are bolted to two symmetrical round bars 808, the outsides of the two round bars 808 are bolted to multiple equidistantly distributed stirring rods 809, and the top inner wall of the protective cover 4 is bolted to a motor 810, and the output end of the motor 810 is connected to the upper side of the main shaft 801 through a coupling.

[0041] Specifically, after tungsten ore and additives are loaded into the mixing barrel 9, the motor 2 810 is started, and the motor 2 810 drives the cross bar 1 802 on the main shaft 801 to rotate, so that the gear 804 on the cross bar 1 802 connected to the secondary shaft 803 can mesh and rotate with the inner gear ring 806, so that the secondary shaft 803 drives the cross bar 2 807 to rotate, and the stirring rod 809 on the round rod 808 stirs and turns the tungsten ore and additives in the mixing barrel 9.

[0042] In a specific application scenario, the uniform stirring module 8 is mainly suitable for the uniform stirring link in the uniform stirring process, that is, the uniform stirring module 8 uses the gear 804 and the inner gear ring 806 to make the secondary shaft 803 rotate with the main shaft 801 as the axis while driving the round rod 808 to rotate with itself as the axis, thereby enhancing the stirring effect of the device, allowing the tungsten ore to fully contact with the additive, ensuring the stirring effect, and improving the efficiency of preparing rough selection feed.

[0043] Working principle: After the tungsten ore and additives are mixed in the mixing barrel 9, the motor 2 810 is started, and the motor 2 810 drives the crossbar 1 802 on the main shaft 801 to rotate, so that the gear 804 connected to the secondary shaft 803 on the crossbar 1 802 can mesh and rotate with the inner gear ring 806, so that the secondary shaft 803 drives the crossbar 2 807 to rotate, so that the stirring rod 809 on the round rod 808 stirs and turns the tungsten ore and additives in the mixing barrel 9. After stirring to form rough selection feed, the discharge pipe 10 draws the rough selection feed in the mixing barrel 9 out of the barrel body 1, and the weight of the mixing barrel 9 is reduced. As a result, the spring 2 626 pulls the movable block 622 in the rectangular groove 621 toward the center, so that the mixing barrel 9 is gradually raised under the push of the push rod 623. After the top block 618 on the raised mixing barrel 9 contacts the connecting rod 619, it pushes the connecting rod 619 to move upward on the vertical groove 616, so that the rack 620 connected to the connecting rod 619 meshes and rotates with the outer gear ring 615, so that the rotating cylinder 605 on the containing box 602 drives the rotating member 609 to connect the bevel groove 613 with the discharge port 606, so that the additive in the containing box 602 can be transported into the mixing barrel through the delivery pipe 607 9 is mixed with tungsten ore. After a certain amount of additives are added, the added weight causes the mixing barrel 9 to drop again, causing the rack 620 to drive the outer gear ring 615 to rotate, causing the rotating barrel 605 to close the discharge port 606 and the channel of the discharge port 606, so that the additives no longer flow into the mixing barrel 9. After the additives stored in the storage barrel 603 are consumed, the pump 707 is started, and the pump 707 transports the additives in the supplementary box 704 into the storage barrel 603 through the extraction pipe 705. After the use of the production time, when the additives in the supplementary box 704 are consumed, the motor 712 is started, and the motor One 712 drives the screw rod 711 to rotate, so that the boss two 710 drives the fitting frame 703 and the supporting plate 702 to descend to the bottom of the fixed frame 701, thereby pulling the bottom end of the extraction tube 705 out of the replenishment box 704, taking out the empty replenishment box 704, placing the new replenishment box 704 on the supporting plate 702 and fitting the replenishment box 704 with the fitting frame 703, starting the motor one 712, so that the supporting plate 702 lifts the replenishment box 704, thereby reinserting the extraction tube 705 into the replenishment box 704, and continuing to transport the additive in the replenishment box 704 into the storage cylinder 603.
