Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bagging equipment, and in particular to an arsenic slag bagging device. Background Art
[0002] Arsenic slag is a hazardous solid waste generated during the antimony smelting process. Its primary component is arsenic trioxide, commonly known as "arsenic," which is highly toxic and water-soluble. During the antimony refining process, soda ash or caustic soda flakes are added for arsenic removal, resulting in a solid scum known as arsenic slag. The treatment of arsenic slag is a significant environmental issue. Traditional methods, such as on-site landfill, are no longer suitable. Modern treatment technologies include harmless disposal and resource utilization. Smelters are generally unable to handle this waste in-house and must bag and transport it to other companies for processing.
[0003] The current arsenic slag packaging bags are as follows Figure 3 As shown, due to its relatively soft nature, workers usually need to hold the bag mouth by hand and put it on the discharge pipe when bagging to prevent the bag from collapsing and causing the slag to overflow during the bagging process. Arsenic slag is highly toxic and poses a major safety hazard to workers. Summary of the Invention

[0027] There is a technical problem that requires staff to support the packaging bags when bagging arsenic slag, which poses a major safety hazard.
[0028] See also Figure 1 The present application provides an arsenic slag bagging device, comprising a mounting platform 1, a discharge pipe 2, a bag opening fixing mechanism 3, and a material shifting mechanism 4. The mounting platform 1 is a rigid plate-like structure suspended above the ground by support rods 101. The height above the ground is set to different heights according to the height of the packaging bag. There are four support rods 101, each located at the bottom of the four corners of the mounting platform 1.
[0029] The discharge pipe 2 is arranged in the middle of the mounting platform 1 and is fixedly connected to the mounting platform 1. The upper end of the discharge pipe 2 is connected to the arsenic slag storage bin or the arsenic slag conveying equipment. The lower end of the discharge pipe 2 extends downward through the mounting platform 1 to discharge the material downward, and the bottom of the discharge pipe 2 is used as a bagging area.
[0030] A rotating shaft 5 is rotatably mounted on each side of the discharge tube 2. Specifically, a through hole is pre-set on the support rod 101, and the left and right ends of the rotating shaft 5 are inserted into the through hole, thereby enabling the rotating shaft 5 to be rotatably mounted on both sides of the discharge tube 2. The two ends of the rotating shaft 5 can also be connected to the support rod 101 via bearings to achieve its rotatable installation. The rotating shaft 5 is provided with a sling hook 6. The sling hooks 6 on the two rotating shafts 5 are arranged on opposite sides. There are two sling hooks 6. The spacing between the two sling hooks 6 is set according to the size of the packaging bag, generally slightly larger than the width of the packaging bag, so that after the sling of the packaging bag is hung on the sling hook 6, the packaging bag can be pulled to the left and right sides and straightened.
[0031] A first connecting rod 7 is fixed to one end of each of the two rotating shafts 5, and the first connecting rods 7 on the two rotating shafts 5 are arranged on opposite sides. The free ends of the first connecting rod 7 are hingedly connected to the second connecting rod 8 and the third connecting rod 9, respectively. The free end of the third connecting rod 9 is hinged to the bottom surface of the mounting platform 1. The hinge points of the second connecting rod 8 and the third connecting rod 9 on both sides are also hinged to the ends of the fourth connecting rod 10. The mounting platform 1, the two third connecting rods 9, and the fourth connecting rod 10 form a parallelogram mechanism. One end of the first cylinder 11 is hinged to the mounting platform 1, and the other end is hinged to the fourth connecting rod 10.
[0032] When hanging the bag, the sling hook 6 is in a lower position to facilitate the hanging of the bag, the second connecting rod 8 and the third connecting rod 9 are folded into a V shape, and the first cylinder 11 is retracted; after the bag is hung, the first cylinder 11 extends, pushing the fourth connecting rod 10 to the left, and the two third connecting rods 9 rotate counterclockwise, pressing the end of the first connecting rod 7 downward through the second connecting rod 8, thereby driving the two rotating shafts 5 to rotate in opposite directions, that is, the rotating shaft 5 on the left rotates counterclockwise and the rotating shaft 5 on the right rotates clockwise, thereby lifting the packaging bag upward for a certain distance until the second connecting rod 8 and the third connecting rod 9 are basically in the same straight line (such as Figure 1 ), so that the packaging bag expands as a whole, effectively preventing the packaging bag from collapsing during the bagging process; after the arsenic slag is bagged, the first cylinder 11 shortens and resets, thereby driving the sling hook 6 to reset.
[0033] The outer periphery of the discharge pipe 2 is provided with a bag opening fixing mechanism 3 for fixing the bag opening of the packaging bag on the discharge pipe 2; the bagging area is provided with a material shifting mechanism 4 for moving the packaging bag filled with material out of the bagging area.
[0034] The usage process of this application is as follows: the packaging bags of appropriate specifications are transported to the material shifting mechanism 4, the two slings of the packaging bags are respectively hung on the sling hooks 6 on both sides, and the bag mouth of the packaging bag is put on the discharge pipe 2; then the first cylinder 11 is extended to lift the packaging bag as a whole, and the packaging bag is pulled to the left and right sides; the material is discharged from the discharge pipe 2, and the arsenic slag is bagged. After the bagging is completed, the first cylinder 11 is shortened and reset to put the packaging bag down.
[0035] The present invention utilizes sling hooks 6 provided on both sides to hook the slings of the packaging bag, allowing the packaging bag to remain in an expanded state throughout the bagging process. This effectively prevents the problem of arsenic slag leakage caused by the collapse of the packaging bag during bagging. Furthermore, workers only need to perform the bagging operation and remove the slings of the packaging bag from the sling hooks 6 after bagging. There is no need to hold the packaging bag during bagging, thus reducing the risk of injury to workers. Furthermore, the present invention utilizes a single first cylinder 11 to drive the two rotating shafts 5 to rotate, effectively reducing the manufacturing cost of the device.
[0036] In some specific embodiments, the discharge pipe 2 is provided with an air inlet pipe 201, which is connected to an external air supply device. The air inlet pipe 201 is provided with a valve. When the staff puts the bag mouth of the packaging bag on the discharge pipe 2, the valve is opened to blow some air into the packaging bag to expand the packaging bag, so as to avoid the packaging bag from folding during bagging, which may cause the packaging bag to be unable to be filled.
[0037] In some embodiments, such as Figure 1 As shown, the bag opening fixing mechanism 3 includes a ring 301 which is sleeved on the outside of the discharge pipe 2. The ring 301 is fixedly connected to the mounting platform 1. A bagging gap is provided between the ring 301 and the discharge pipe 2. When bagging, the bag opening of the packaging bag is passed through the ring 301 from the bagging gap and then folded downward. The ring 301 provides certain support for the bag opening of the packaging bag, thereby effectively avoiding the technical problem of the bag opening of the packaging bag falling off during bagging.
[0038] In some embodiments, Figure 2 As shown, the bag mouth fixing mechanism 3 includes two semicircular locking rings 302, the inner diameter of the locking ring 302 matches the inner diameter of the discharge pipe 2, and the two locking rings 302 are hinged to the mounting platform 1 through a fifth connecting rod 303 respectively; the sixth connecting rod 304 and the seventh connecting rod 305 are hinged between the two fifth connecting rods 303 in sequence, and the hinge points of the sixth connecting rod 304 and the seventh connecting rod 305 are hinged to one end of the second cylinder 306, and the other end of the second cylinder 306 is connected to the mounting platform 1.
[0039] During bagging, the second cylinder 306 is extended, and the two fifth connecting rods 303 are stretched out, thereby opening the two locking rings 302 to facilitate bagging. After bagging is completed, the second cylinder 306 is shortened, driving the two fifth connecting rods 303 toward each other via the sixth connecting rod 304 and the seventh connecting rod 305. The two locking rings 302 press the bag opening against the discharge pipe 2 from the left and right sides, effectively preventing the bag opening from falling off the discharge pipe 2 during bagging.
[0040] In some embodiments, Figure 1As shown, the material shifting mechanism 4 includes a guide rail 401, a transport vehicle 402, a conveying motor 403, and a conveying chain 404. The guide rail 401 is mounted on the ground, with its left and right ends extending outward from the bagging area. The transport vehicle 402 is mounted on the guide rail 401, and the conveying chain 404 is disposed below the transport vehicle 402 and is driven to rotate by the conveying motor 403. Specifically, the conveying motor 403 is a stepper motor or a servo motor. The output shaft of the conveying motor 403 is connected to one of the sprockets of the conveying chain 404, and one or more links of the conveying chain 404 are fixedly connected to the transport vehicle 402. In this way, driven by the conveying motor 403, the conveying chain 404 rotates, thereby driving the transport vehicle 402 to move on the guide rail 401, and transporting the bagged arsenic slag out of the bagging area.
[0041] In this embodiment, the length of the transport vehicle 402 is slightly greater than the length of the two bagging areas. In this way, the transport vehicle 402 can be divided into two sections, one section is in the bagging area, and the other section is located outside the bagging area, which can perform forklift operations on the packaging bags, making it more convenient to use.
[0042] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
