Description

Technical Field

[0001] This utility model relates to the field of smelting furnace charging, and in particular to a smelting furnace charging device. Background Technology

[0002] The smelting furnace is the core equipment in pyrometallurgical copper smelting. It is mainly used to heat copper concentrate or copper alloy to a high-temperature molten state to separate copper from impurities. Among them, feeding is a key step before smelting, which requires ensuring that the raw material ratio is accurate, the mixing is uniform, and specific physical conditions are met.

[0003] Chinese patent CN211425058U discloses a smelting furnace feeding device. During the feeding process, the hopper will reciprocate with a large amplitude due to the elastic force provided by the first and second elastic elements, so that the material in the hopper can be completely fed into the smelting furnace.

[0004] In the above scheme, personnel need to grab the handle and push the hopper full of material to feed the material. However, the smelting furnace can only be fed after the rear furnace door is opened, which makes the surrounding area high temperature. Manual feeding is time-consuming and labor-intensive, and the amount of material that can be added at one time is small, resulting in low feeding efficiency. Therefore, a smelting furnace feeding device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a charging device for a smelting furnace, so as to solve the problems mentioned in the background art, such as the time-consuming and labor-intensive nature of manual charging, the small amount of material that can be added at one time, and the low charging efficiency. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A smelting furnace feeding device includes a smelting furnace, a crossbeam above the smelting furnace, a first support and a second support on the crossbeam, the first support being directly above the smelting furnace, a movable worktable inside the crossbeam, a movable plate and a feeding box arranged sequentially below the worktable, a first drive mechanism at one end of the crossbeam for moving the worktable horizontally and the movable plate vertically via ropes, a second drive mechanism for driving the feeding box to flip on one side, and a third drive mechanism above the worktable for limiting the position of the worktable.

[0007] Preferably, both the first and second supports are inverted U-shaped structures, with a first through hole and a second through hole respectively on the top of the first and second supports, and a slide rail is provided inside the crossbeam, with the worktable connected to the slide rail via a slider.

[0008] Preferably, the workbench is provided with a column and a pulley on top, and a guide column is provided below the workbench. The lower end of the guide column passes through the movable plate. The first driving mechanism is a winch. One end of the winch is mounted on the crossbeam, which is higher than the other end. One end of the rope is connected to the winch, and the other end of the rope first passes through the column, then wraps around the pulley, then passes through the workbench, and finally connects to the top of the movable plate.

[0009] Preferably, both sides of the feeding box are provided with connecting plates. The second driving mechanism includes a first motor, a first driving gear and a first driven gear. The first motor is fixed on the connecting plate. The first driving gear is connected to the shaft of the first motor. The first driving gear and the first driven gear mesh. The first driven gear is connected to the feeding box through a rotating shaft. The rotating shaft passes through the connecting plate and is connected to the bearing of the connecting plate.

[0010] Preferably, the third drive mechanism includes a second motor, a second drive gear, a second driven gear, a stud, and a sleeve. The second motor is fixed to the side of the column, the second drive gear is connected to the shaft of the second motor, the second drive gear meshes with the second driven gear, the upper end of the sleeve is connected to the second driven gear, and the lower end of the sleeve is connected to the column through a bearing.

[0011] Preferably, the stud is located inside the sleeve, and the stud is threadedly connected to the sleeve. A locking rod and a pressure plate are respectively provided at the upper and lower ends of the stud, and the pressure plate is located inside the column.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features an inclined beam above the smelting furnace, with a winch positioned at the high end of the beam. Initially, the worktable and feeding box are located at the low end of the beam. When the worktable is locked below the second support, the winch first moves the feeding box upwards. Then, the worktable is unlocked, and the winch moves both the worktable and the feeding box downwards simultaneously. Afterwards, when the worktable is locked below the first support, the winch moves the feeding box downwards, and a first motor rotates the feeding box, allowing material to enter the smelting furnace. Finally, the winch moves the feeding box upwards, and the worktable is unlocked from the first support. The worktable and feeding box then slowly slide to the low end of the beam, thus achieving large-scale automatic material feeding, reducing manpower waste, and ensuring personnel safety by eliminating the need for personnel to approach the smelting furnace.

A first support 101 and a second support 103 are provided on the crossbeam 1. The first support 101 is located directly above the smelting furnace 3. A movable workbench 6 is provided inside the crossbeam 1. A movable plate 5 and a feeding box 4 are arranged in sequence below the workbench 6. A winch 2 is provided at the high end of the crossbeam 1. A first motor 7 is provided on one side of the feeding box 4. A second motor 8 is provided above the workbench 6.

[0019] The first support 101 and the second support 103 are both inverted U-shaped structures. The first support 101 and the second support 103 are respectively provided with a first through hole 102 and a second through hole 104. The inside of the crossbeam 1 is provided with a slide rail 105. The worktable 6 is connected to the slide rail 105 through a slider 601.

[0020] Example 1: Please refer to Figure 1-3 In this embodiment of the utility model, a smelting furnace feeding device has a column 602 and a pulley 603 on the top of the workbench 6, and a guide column 604 on the bottom of the workbench 6. The lower end of the guide column 604 passes through the movable plate 5. One end of the winch 2 is mounted on the crossbeam 1, which is higher than the other end. One end of the rope 201 is connected to the winch 2, and the other end of the rope 201 first passes through the column 602, then wraps around the pulley 603, then passes through the workbench 6, and finally connects to the top of the movable plate 5.

[0021] Both sides of the feeding box 4 are provided with connecting plates 401. The upper end of the connecting plate 401 is connected to the movable plate 5. The first motor 7 is fixed on the connecting plate 401. The first driving gear 701 is connected to the shaft of the first motor 7. The first driving gear 701 and the first driven gear 702 mesh. The first driven gear 702 is connected to the feeding box 4 through a rotating shaft. The rotating shaft passes through the connecting plate 401 and is connected to the bearing of the connecting plate 401. The first motor 7 drives the first driving gear 701 and the first driven gear 702 to rotate in sequence, thereby controlling the feeding box 4 to flip. When the open end of the feeding box 4 faces downward, the material completely detaches from the inside of the feeding box 4.

[0022] The second motor 8 is fixed to the side of the column 602. The second driving gear 801 is connected to the shaft of the second motor 8. The second driving gear 801 meshes with the second driven gear 802. The upper end of the sleeve 804 is connected to the second driven gear 802. The lower end of the sleeve 804 is connected to the column 602 through a bearing. The stud 803 is located inside the sleeve 804. The stud 803 and the sleeve 804 are threadedly connected. The upper and lower ends of the stud 803 are respectively provided with a locking rod 8031 ​​and a pressure plate 8032. The pressure plate 8032 is located inside the column 602. The second motor 8 drives the second driving gear 801, the second driven gear 802 and the sleeve 804 to rotate in sequence, thereby controlling the stud 803 to move up and down. When the stud 803 gradually moves downward, the pressure plate 8032 gradually presses down on the rope 201, so that the rope 201 is fixed inside the column 602.

[0023] In addition, the first motor 7, the first driving gear 701 and the first driven gear 702 are all located inside the first protective housing, which is made of high-temperature resistant material. The second motor 8, the second driving gear 801, the second driven gear 802 and the stud 803 are all located inside the second protective housing, which is also made of high-temperature resistant material. The locking rod 8031 ​​passes through the second protective housing, and a sealing ring is provided between the locking rod 8031 ​​and the second protective housing. The first and second protective housings are used to prevent dust in the workshop from getting stuck between the gears, and all parts of this device are made of high-temperature resistant material.

[0024] When the workbench 6 is below the second support 103, the second motor 8 drives the locking rod 8031 ​​to insert into the second through hole 104, thus fixing the workbench 6 below the second support 103. At this time, the winch 2 first moves the material-filled loading box 4 upward via the rope 201, and then the second motor 8 controls the stud 803 to descend, causing the locking rod 8031 ​​to disengage from the second through hole 104, and driving the pressure plate 8032 to fix the rope 201 inside the column 602. The winch 2 then moves the workbench 6 downward below the first support 101 via the rope 201, and then the workbench is fixed by inserting the locking rod 8031 ​​into the first through hole 102. 6 is fixed below the first support 101. At this time, the winch 2 first drives the feeding box 4 filled with material to move downward through the rope 201, so that the feeding box 4 is above the furnace door of the smelting furnace 3. Then the feeding box 4 is flipped until the material is completely inside the smelting furnace 3. Finally, the winch 2 drives the feeding box 4 to move upward, and the locking rod 8031 ​​is released from the inside of the first through hole 102. At this time, the worktable 6 is released from the position restriction state, and the pressure plate 8032 presses down the rope 201. The worktable 6 then slowly slides to the lower end of the crossbeam 1, thereby realizing the automatic feeding of large batches of materials, reducing the waste of human resources, and eliminating the need for personnel to approach the smelting furnace 3, thus ensuring personnel safety.

[0025] Both the first bracket 101 and the second bracket 103 are equipped with laser-type trigger switches on their sides. When the locking rod 8031 ​​is in place, that is, when the locking rod 8031 ​​is directly below the first through hole 102 or the second through hole 104, the laser-type trigger switch senses the locking rod 8031, the second motor 8 starts, and controls the locking rod 8031 ​​to be inserted into the first through hole 102 or the second through hole 104. At this time, the winch 2 controls the feeding box 4 to move up and down. When the feeding box 4 rises to the top, the second motor 8 starts, and controls the locking rod 8031 ​​to disengage from the first through hole 102 or the second through hole 104. At this time, the winch 2 controls the feeding box 4 to move along the slide 105.

[0026] The working principle of this utility model is as follows: An inclined crossbeam 1 is set above the smelting furnace 3, and the winch 2 is located at the high end of the crossbeam 1. The worktable 6 and the feeding box 4 are initially located at the low end of the crossbeam 1. When the worktable 6 is locked below the second support 103 by inserting the locking rod 8031 ​​into the second through hole 104, the winch 2 first drives the feeding box 4 to move upward. Then the worktable 6 is unlocked, and the winch 2 then drives the worktable 6 and the feeding box 4 to move simultaneously downwards from the first support 101. Then, when the workbench 6 is locked below the first support 101, the winch 2 drives the feeding box 4 to move down, and then the first motor 7 drives the feeding box 4 to flip, so that the material enters the melting furnace. Finally, the winch 2 drives the feeding box 4 to move up, and the workbench 6 is released from the locked state on the first support 101. The workbench 6 and the feeding box 4 slowly slide to the lower end of the crossbeam 1, thus realizing the automatic feeding of materials in large quantities, reducing the waste of human resources, and eliminating the need for personnel to approach the melting furnace 3, thus ensuring personnel safety.
