Description

Technical Field

[0001] This utility model relates to the field of arsenic sulfide slag transportation technology, specifically to a secondary bagging device for arsenic sulfide slag. Background Technology

[0002] Arsenic sulfide slag is an arsenic-containing solid waste generated during metallurgical or chemical processes. Its main component is arsenic sulfide, and it typically originates from processes such as smelting arsenic-containing ores, flue gas purification, acidic wastewater treatment, or hydrometallurgical processes. Due to the high toxicity and potential environmental risks of arsenic, arsenic sulfide slag is classified as hazardous waste and requires harmless treatment or safe disposal to prevent arsenic from migrating into the environment and causing pollution.

[0003] Before transporting arsenic sulfide slag, it is necessary to pack and seal it. The packaging bags for packing arsenic sulfide slag are usually made of leak-proof high-density polyethylene bags, and flexible container bags are put on the outside of the high-density polyethylene bags. The leak-proof high-density polyethylene bags are sealed by heat sealing, and the opening of the flexible container bags is sewn closed. Only after the above steps are taken to pack the arsenic sulfide slag can it be transported.

[0004] During the transportation or transfer of arsenic sulfide slag, it is necessary to inspect the sealing of the packaging bags to prevent the outer packaging seals from loosening due to bumps or operational errors during transportation, which could lead to secondary risks. According to the standards for the transportation of dangerous goods, when the inner bag of arsenic sulfide slag is sealed intact but the outer flexible container bag seal is loose, the seal can be temporarily tightened again. However, during transportation, it is not possible to use sealing equipment to resew the opening of the outer flexible container bag, and sealing equipment cannot be carried with the vehicle. Generally, nylon ropes or cable ties are used to re-tighten the opening of the outer flexible container bag, which is prone to loosening again. Alternatively, a new outer flexible container bag can be manually placed on top of the loose outer flexible container bag. This requires manually opening the bag and pushing the new outer flexible container bag downwards to wrap the loose outer flexible container bag. However, this inevitably involves contact between the operator and the outer packaging of the arsenic sulfide slag, posing a certain safety hazard. Furthermore, manual bagging of arsenic sulfide slag packaging is inefficient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a secondary bagging device for arsenic sulfide slag. It features an upward-moving, quick-closing clamping structure that locks in place, connecting the opening of a new external flexible container bag to this structure. By releasing the positioning bolt and utilizing the restoring force of the return spring, the sliding block connected to the quick-closing clamping structure is moved towards the bottom plate clamping direction. This allows for the rapid slippage of a new external flexible container bag onto an old flexible container bag with a loose or open seal, and then tightened with a strap. The device is simple to operate, avoids direct contact between the operator and the arsenic sulfide slag packaging with a loose or open outer seal, and improves the safety of secondary bagging, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a secondary bagging device for arsenic sulfide slag, comprising a base clamp, a slide rail clamp perpendicular to the base clamp welded to its top surface, a limiting plate welded to the top surface of the slide rail clamp, a slider clamp slidably connected to the slide rail clamp, a positioning bolt clamp threaded to the middle of the back of the slider clamp, a connector clamp welded to a section of the bottom surface of the slider clamp, another connector clamp welded to the top surface of the base clamp, and return spring clamps provided on opposite sides of the two connector clamps, with the two ends of the return spring clamps respectively welded to the connector clamps, and a quick bagging clamping structure provided on the front of the slider clamp.

[0007] As a preferred technical solution of this utility model, each pair of connector clamps and the connected reset spring clamps form a set of reset mechanisms. The reset mechanisms are arranged in two sets. The reset spring clamps are located inside the slide rail clamps, and the reset spring clamps are perpendicular to the top surface of the base clamps.

[0008] As a preferred technical solution of this utility model, the quick bag clamping structure is composed of elastic clamping sheet clamping, magnetic block clamping and pressure plate clamping.

[0009] As a preferred technical solution of this utility model, the elastic clamping piece is welded to the middle of the back side and the slider clamping front side. The elastic clamping piece clamps a "C"-shaped structure made of magnetic metal material. Magnetic blocks for clamping external flexible container bags are adsorbed at both ends of the front side and the two ends of the back side of the elastic clamping piece.

[0010] As a preferred embodiment of this invention, a silicone pad is attached to the front of the magnetic block clamp.

[0011] As a preferred technical solution of this utility model, the top surface of the elastic clamping piece is symmetrically welded with pressure plates at both ends, and the pressure plates are used to press the outer wall of the external flexible container bag during the bagging process.

[0012] As a preferred technical solution of this utility model, the quick bag clamping structure is composed of a bent rod clamping, a columnar block clamping, a clamping claw clamping, and a magnetic block clamping.

[0013] As a preferred technical solution of this utility model, one end of the bent rod clamp is welded to the middle of the top surface of the columnar block clamp, and a clamping claw is welded to the bottom surface of the columnar block clamp. The clamping claw is a claw structure made of elastic magnetic metal material, and there are several clamping claws welded in a circumferential array on the bottom surface of the columnar block clamp. The bottom end of the clamping claw is attracted to a magnetic block for clamping the external flexible container bag.

[0014] As a preferred technical solution of this utility model, the front of the magnetic block is bonded with a silicone pad.

[0015] As a preferred technical solution of this utility model, the top surface of the slider clamp is provided with an insertion hole extending through its bottom surface. A rubber sleeve clamp is glued into the insertion hole. A limiting ring clamp is welded to the bottom end of the bent rod clamp. The bent rod clamp is inserted into the slider clamp through the insertion hole. When the bent rod clamp is fully inserted into the slider clamp, the bottom surface of the limiting ring clamp and the top surface of the slider clamp are in contact.

[0016] Compared with the prior art, this utility model provides a secondary bagging device for arsenic sulfide slag, which has the following beneficial effects:

[0017] 1. This utility model uses an upward-moving quick-bag clamping structure to lock and connect the opening of a new external flexible container bag to its quick-bag clamping structure. By releasing the positioning bolt and utilizing the restoring force of the return spring, the sliding block connected to the quick-bag clamping structure is moved towards the bottom plate clamping direction. This allows the new external flexible container bag to be quickly placed over an old flexible container bag with a loose seal or opening, and then tightened with a strap. The operation is simple, avoiding direct contact between the operator and the arsenic sulfide slag packaging with a loose or open outer packaging, thus improving the safety of secondary bagging.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7 A secondary bagging device for arsenic sulfide slag includes a base 1, a slide rail 2 welded to the top surface of the base 1, and the slide rail 2 is welded to one side of the middle of the top surface of the base 1. The weight of the base 1 is much greater than the weight of other components of the secondary bagging device for arsenic sulfide slag, so as to prevent the secondary bagging device for arsenic sulfide slag from tipping over during use. A limit plate is welded to the top surface of the slide rail 2, and a slider 3 is slidably connected to the slide rail 2. The slider 3 can move up and down on the slide rail 2. The limit plate is used to limit the slider 3 to prevent the slider 3 from falling off the slide rail 2.

[0032] A positioning bolt 4 is threaded to the middle of the back of the slider 3. After the positioning bolt 4 is tightened, it contacts the track of the slide rail 2. The side of the positioning bolt 4 that contacts the slide rail 2 is coated with friction material. When the positioning bolt 4 is tightened and fully contacts the slide rail 2, a positive pressure is formed on the contact surface between the slide rail 2 and the slider 3. As the positioning bolt 4 is tightened, the preload generated by the positioning bolt 4 increases, the positive pressure generated increases, and the static friction generated increases, so the slider 3 can be stopped at a certain position on the slide rail 2.

[0033] like Figure 3 and Figure 7 As shown, connectors 5 are welded to the bottom surface of slider 3 and the top surface of base 1 respectively. A return spring 6 is connected to the opposite surfaces of the two connectors 5. The two ends of the return spring 6 are welded to the two connectors 5 respectively. Other connectors can also be used to connect the return spring 6 and the connectors 5, as long as the return spring 6 does not fall off the connectors 5. When slider 3 moves to the top of slide rail 2, return spring 6 is stretched and extended. After the positioning bolt 4 is tightened, slider 3 stops at a certain position on slide rail 2. When the positioning bolt 4 is loosened, slider 3 is subjected to the restoring force of return spring 6 and automatically moves towards base 1.

[0034] Each pair of connectors 5 and the reset spring 6 connected to each pair of connectors 5 constitute a reset mechanism. Two sets of reset mechanisms are provided, and the reset spring 6 is located inside the slide rail 2 and is perpendicular to the top surface of the base 1.

[0035] like Figure 1 and Figure 5 As shown, a quick bag-holding structure is provided on the front of the slider 3. The quick bag-holding structure is used to hold the external flexible container bag at the opening position of the external flexible container bag. As the slider 3 moves downward, it puts the external flexible container bag over the original loosely sealed external flexible container bag of arsenic sulfide slag.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in the first embodiment of this utility model, the quick bag clamping structure is composed of an elastic clamping piece 701, a magnetic block 702, and a pressure plate 703.

[0037] The middle of the back of the elastic clamping piece 701 is welded to the front of the slider 3. The elastic clamping piece 701 is made of magnetic metal material and is C-shaped. The open space formed in the middle is larger than the external flexible container bag containing arsenic sulfide slag. According to conventional transportation standards and for transportation safety considerations, the external flexible container bags used for arsenic sulfide slag are generally 1000 kg or less in size to reduce the risk of leakage or breakage of a single bag. Usually, the height of these external flexible container bags is about 1000 mm-1200 mm and the diameter is about 900 mm-1100 mm. That is, the open space formed in the middle of the elastic clamping piece 701 is greater than 1100 mm. Since the elastic clamping piece 701 is elastic, even if the external flexible container bag is slightly larger than 1100 mm, a new external flexible container bag can be put on the outside of the original external flexible container bag through the quick bag clamping structure.

[0038] Magnetic blocks 702 are attached to both ends of the front and back of the elastic clamping piece 701. A silicone pad 7001 is adhered to the front of the magnetic block 702. The function of the silicone pad 7001 is to connect the opening of the external flexible container bag to the elastic clamping piece 701 using the magnetic blocks 702, thereby fixing the external flexible container bag onto the elastic clamping piece 701. The specific clamping process is as follows:

[0039] The opening of the new external flexible container bag is attached to the front and back of the elastic clamping piece 701, respectively, and the magnetic block 702 and the elastic clamping piece 701 are attracted to each other, so that the external flexible container bag is between the magnetic block 702 and the elastic clamping piece 701, thereby realizing the quick bag clamping structure to clamp the external flexible container bag.

[0040] like Figure 3 , Figure 4 As shown, two pressure plates 703 are welded to both ends of the top surface of the elastic clamping piece 701, and the two pressure plates 703 are symmetrical to each other. The function of the pressure plates 703 is to press the outer wall of the new external flexible container bag during the bagging process, so that the inner wall of the new external flexible container bag and the outer wall of the old external flexible container bag are in contact.

[0041] During use, if the seal of the flexible container bag for arsenic sulfide slag becomes loose or opens during transportation or transfer, remove the secondary bagging device for arsenic sulfide slag from the cargo compartment and place it next to the loose or open flexible container bag. Take out a new outer flexible container bag, move slider 3 to move the quick bagging clamping structure above the arsenic sulfide slag packaging, tighten the positioning bolt 4, stop slider 3 at the top position of slide rail 2, remove magnetic block 702, attach the opening of the new outer flexible container bag to the elastic clamping piece 701, and then attach magnetic block 702. The new external flexible container bag is held in place by adhering to the front and back of the elastic clamping piece 701. The bottom of the new external flexible container bag is placed on top of the old external flexible container bag. The positioning bolt 4 is rotated to release it. The slider 3 is moved towards the base 1 under the restoring force of the return spring 6, which moves the opening of the new external flexible container bag towards the base 1. The new external flexible container bag is then placed over the old external flexible container bag with its opening facing down. Finally, the new external flexible container bag is tightened in the middle with a strap to complete the secondary bagging.

[0042] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in the second embodiment of this utility model, the quick bag clamping structure is composed of a bent rod 801, a columnar block 802, a clamping claw 803, and a magnetic block 804.

[0043] like Figure 5 and Figure 6 As shown, the shorter end of the bent rod 801 is welded to the middle of the top surface of the columnar block 802. Multiple clamping claws 803 are welded to the bottom surface of the columnar block 802, and the multiple clamping claws 803 are welded to the bottom surface of the columnar block 802 in a circumferential array. The clamping claws 803 are claw structures made of elastic magnetic metal material. The elastic clamping claws 803 can better fit the surface of the old external flexible container bag.

[0044] A through-hole is provided at the middle of the top surface of slider 3, and a rubber sleeve 301 is glued inside the through-hole. The bent rod 801 is inserted into slider 3 through the through-hole. The rubber sleeve 301 increases the friction between slider 3 and bent rod 801, making the connection between them more stable and ensuring that slider 3 and bent rod 801 do not separate during bagging. In addition, a limiting ring 8001 is welded to the bottom end of bent rod 801. When bent rod 801 is fully inserted into slider 3, the bottom surface of limiting ring 8001 is tightly attached to the top surface of slider 3, preventing bent rod 801 from being over-inserted into slider 3.

[0045] The bottom end of the clamping claw 803 is attached to a magnetic block 804. The number of magnetic blocks 804 is the same as the number of clamping claws 803. The function of the magnetic blocks 804 to hold the clamping claws 803 together is to clamp and fix the opening of the new external flexible container bag to the clamping claws 803. Then, when the clamping claws 803 move towards the base 1, they will cause the new external flexible container bag to be put onto the old external flexible container bag. Since the clamping claws 803 are made of elastic metal material, during the bag-putting process, if the diameter of the old external flexible container bag is larger than the diameter of the circle formed by the bottom end of the clamping claws 803, the clamping claws 803 will clamp the old external flexible container bag through the new external flexible container bag, so that the new external flexible container bag fits the surface of the old external flexible container bag more closely.

[0046] The front of the magnetic block 2 804 is also attached with a silicone pad 2 8002, which prevents the magnetic block 2 804 from damaging the surface of the new external flexible container bag when it attracts the clamping claw 803.

[0047] During use, if the seal of the flexible container bag for arsenic sulfide slag becomes loose or opens during transportation or transfer, remove the secondary bagging device for arsenic sulfide slag from the cargo compartment and place it next to the loose or open flexible container bag. Take out a new outer flexible container bag, move slider 3 to move the quick bagging clamping structure above the arsenic sulfide slag packaging, tighten the positioning bolt 4, stop slider 3 at the top position of slide rail 2, remove magnetic block 804, and place the opening of the new outer flexible container bag at the bottom of the outer wall of the clamping claw 803 facing outwards, and then attach magnetic block 804. At the bottom of the clamping claw 803, the new external flexible container bag is connected to the clamping claw 803, so that the clamping claw 803 can clamp the external flexible container bag. The bottom of the new external flexible container bag is placed on top of the old external flexible container bag. The positioning bolt 4 is released, and the slider 3 is moved towards the base 1 under the restoring force of the return spring 6. This causes the opening of the new external flexible container bag to move towards the base 1, so that the opening of the new external flexible container bag is placed on the outside of the old external flexible container bag with the opening facing down. Then, the middle of the new external flexible container bag is tightened with a strap to complete the secondary bagging.

[0048] The above technical solution demonstrates that this secondary bagging device for arsenic sulfide slag has a simple structure, is easy to operate, and occupies little space, allowing it to be carried by transport vehicles. During transportation or transfer of arsenic sulfide slag, if the seal of the outer flexible container bag is found to be loose or open, the secondary bagging device can be removed, the quick-release bagging clamping structure moved upwards and locked, and the opening of the new outer flexible container bag connected to its quick-release bagging clamping structure. The positioning bolt is released, and the restoring force of the return spring 6 drives the slider 3 connected to the quick-release bagging clamping structure to move towards the base 1. This allows the new outer flexible container bag to be quickly placed over the old flexible container bag with a loose or open seal, and then tightened with a strap. The operation is simple, avoiding direct contact between the operator and the arsenic sulfide slag packaging with a loose or open outer seal, thus improving the safety of the secondary bagging.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
