Description

Technical Field

[0001] This utility model relates to the field of arsenic sulfide slag treatment technology, specifically to a device for the storage and bag-breaking treatment of arsenic sulfide slag in rigid landfills. Background Technology

[0002] Arsenic sulfide slag is a hazardous waste containing arsenic, formed during the copper ore production process after high-temperature smelting or chemical treatment of arsenic elements associated with copper ore. The arsenic in arsenic sulfide slag is highly toxic, and its treatment must comply with the "GB18598-2019 Standard for Pollution Control of Hazardous Waste Landfill". For arsenic slag with an arsenic content higher than 5%, it must be placed in a rigid landfill. The rigid landfill silo for arsenic sulfide slag is a special landfill facility designed for hazardous waste containing arsenic sulfide, referred to as "arsenic sulfide slag". It is an important component of hazardous waste safe landfills. Its core objective is to prevent the leakage of toxic substances (such as arsenic, heavy metals, etc.) in arsenic sulfide slag through rigid structure, multiple seepage prevention and environmental control technologies, so as to avoid pollution of soil, groundwater and atmosphere.

[0003] When rigidly landfilling arsenic sulfide slag, it is necessary to break the bags. As a toxic and hazardous material, mechanical methods should be used for bag breaking. However, currently, manual bag breaking is supplemented by mechanical lifting, such as CN 222292208 U, a rigid landfill lifting bag cutter. Paragraphs 0027-0029 of this application disclose "holding the connecting rod, moving the U-shaped slide bar to the side of the hazardous waste that needs to be cut, pulling the pull ring handle to increase the distance between the two ends of the slide bar and then releasing it, fixing it to the waste that needs to be cut, and then, by pulling the moving handle, causing the blade groove and the blade on the blade groove to move on the U-shaped slide bar, cutting the ton bag containing the waste, and the hazardous waste falling into the landfill. Finally, pulling the pull ring handle again to separate the slide bar end from the ton bag." Although the aforementioned technical solution breaks the bags quickly and stably, even if workers wear protective clothing, there is no guarantee that they will not come into contact with highly toxic substances like arsenic sulfide slag during bag breaking. As long as workers are in close contact with the bag breaking process, occupational diseases are only a matter of time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for the storage and bag-breaking treatment of arsenic sulfide slag in rigid landfills. The device has the advantages of automatically breaking bags and storing arsenic sulfide slag, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for receiving and breaking bags of arsenic sulfide slag in a rigid landfill, comprising a receiving platform for receiving arsenic sulfide slag packaging bags hoisted by hoisting equipment or transported by conveyor belt, the receiving platform being located above the opening of the rigid landfill, the surface of the receiving platform having an opening wider than the length of the arsenic sulfide slag packaging bag, multiple cutters being installed at intervals inside the opening, baffles being installed above the opening and on both sides of the receiving platform, and multiple rollers being arranged between the two baffles and directly above the opening, the distance between the multiple rollers and the opening decreasing sequentially.

[0006] Preferably, a guide plate is also installed at the front end of the receiving platform. The guide plate is tilted upward at an angle of 25 to 30 degrees to guide the incoming arsenic sulfide slag packaging bag to below multiple rollers.

[0007] Preferably, the plurality of rollers are also connected to shafts that pass through and are rotatably connected to the baffle. Each of the plurality of shafts is fixedly mounted with a sprocket, and a chain is engaged on the surface of the sprocket. The plurality of sprockets and the chain are linked together, and the shaft connected to the first roller is connected to a servo motor through a planetary gearbox.

[0008] Preferably, the roller surface is further provided with raised strips to increase the contact area with the arsenic sulfide slag packaging bag.

[0009] Preferably, the height of the plurality of cutters is the same as the opening height.

[0010] Preferably, the height of the plurality of cutters increases from low to high, and the height of the rear end of the cutter is close to that of the roller, forming a gap between them.

[0011] Compared with the prior art, this utility model provides a device for the loading and bag-breaking of arsenic sulfide slag in rigid landfills, which has the following beneficial effects: 1. This utility model involves a bag of arsenic sulfide slag sliding down to the top of an opening. At this point, a remote start activates a servo motor that drives multiple rollers to rotate. The roller closest to the guide plate, upon contact with the bag, generates friction that pulls it towards the opening. The bag, pressed and moved towards the opening by the roller, then contacts a cutter flush with the opening. Due to the bag's own weight and the pressure of the rollers, it adheres tightly to the cutter. Because the contact area between the cutter and the bag is small, the pressure is greater, causing the cutter to puncture the bag. As the bag continues to be contacted and moved by the rollers, the height between the rollers and the opening becomes increasingly closer. Therefore, the pressure on the bag increases as it moves further back from the opening, resulting in more pressure being applied. The bag is then completely cut open and moved out of the receiving platform by the rollers located behind the opening, falling into the rigid landfill bin. This achieves the beneficial effect of automatically breaking open bags of arsenic sulfide slag and processing it for storage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 The device for receiving and breaking bags of arsenic sulfide slag in a rigid landfill includes a receiving platform 1 for receiving arsenic sulfide slag packaging bags hoisted by hoisting equipment or transported by conveyor belt. The receiving platform 1 is located above the opening of the rigid landfill. An opening 101 with a width exceeding the length of the arsenic sulfide slag packaging bag is opened on the surface of the receiving platform 1. Multiple cutters 102 are installed at intervals inside the opening 101. Baffles 2 are installed above the opening 101 and on both sides of the receiving platform 1. Multiple rollers 3 are set between the two baffles 2 and directly above the opening 101. The distance between the multiple rollers 3 and the opening 101 decreases sequentially.

[0016] The servo motor model is BYC20-80B3R215C5-C. The servo motor surface is also equipped with a protective shell, which is fixed with screws to protect the internal body. Since the addition of a protective shell is a structure that is most common to those skilled in the art, it will not be explained in detail.

[0017] The raised strip 303 is installed around the surface of the roller 3, creating an uneven surface that increases the contact area with the arsenic sulfide slag packaging bag. This allows multiple rollers 3 to engage in a gear-like manner when they contact the arsenic sulfide slag packaging bag, gripping it and moving it towards the rear of the receiving platform 1. This allows the bag to maintain pressure while continuously contacting the cutter 102. Example 1

[0018] The existing technology, as described in CN 222292208 U, still relies on tools for manually breaking bags, which can lead to close contact with arsenic and potentially induce cancer. Therefore, this application addresses this issue by placing the receiving platform 1 above a rigid landfill silo and aligning its tail end with the silo. A hoist or conveyor belt is then used to transport the bags containing arsenic sulfide slag to the receiving platform 1. The guide plate 103 at the front of the receiving platform 1 is designed to tilt upwards, allowing it to travel at an angle relative to the opening 101. The arsenic sulfide slag bags, under the influence of gravity, slide downwards from the guide plate 103 onto the opening 101. At this point, a 150-F480NBD / B servo motor soft starter or the remote start technology disclosed in CN116633200B is used for remote starting. This causes the output of the servo motor to be reduced in speed and torque increased by a planetary reducer, which then drives multiple rollers 3 to rotate. When the multiple rollers 3 begin to rotate, according to the appendix of the instruction manual… Figure 1-2 It is known that the roller 3 closest to the guide plate 103 is at the highest position relative to the opening 101, but this height is not higher than the thickness of the packaging bag containing arsenic sulfide slag. Therefore, the friction generated by the roller 3 closest to the guide plate 103 upon contact with the arsenic sulfide slag packaging bag pulls it towards the opening 101. At this time, the packaging bag, pressed and moved towards the opening 101 by the roller 3, contacts the cutter 102 flush with the opening 101. Due to the weight of the arsenic sulfide slag packaging bag itself and the pressure of the roller 3, it adheres to the cutter 102. Since the contact area between the cutter 102 and the packaging bag is small, the pressure is greater. At this time, the cutter 102 cuts through the arsenic sulfide slag packaging bag. Furthermore, as the arsenic sulfide slag packaging bag continues to be contacted and moved by multiple rollers 3, the height between the multiple rollers 3 and the opening 101 becomes increasingly closer. Therefore, the pressure on the arsenic sulfide slag packaging bag increases further back from the opening 101, and more of it is pressed down. Please refer to the appendix of the instruction manual. Figure 2 At this point, the arsenic sulfide slag packaging bag was completely cut open, and then moved out of the receiving platform 1 and fell into the rigid landfill by the roller 3 located behind the opening 101.

[0019] For further details, please refer to the attached instruction manual. Figure 2Below the opening 101, there is also an inclined plate for receiving the arsenic sulfide slag that falls when the arsenic sulfide slag packaging bag is cut open at the opening 101 by the cutter 102. The inclined plate uses gravity to cause the falling arsenic sulfide slag to fall into the rigid landfill below. Example 2

[0020] In Example 1, the arsenic sulfide slag is brought into contact with the cutter by the downward pressure of the roller 3 to break the bag. However, since the cutter 102 is flush with the opening 101 and the rigid landfill is an open-air operation, sudden rain may occur. At this time, the rainwater will soak the arsenic sulfide slag packaging bag and reduce the friction. In order to avoid the roller 3 spinning idly due to reduced friction, the number of cutters 102 in this example is less than 50% of that in the first example. In addition, the height of the cutter in this example increases from low to high, and the height of the rear end of the cutter 102 is close to that of the roller 3, forming a gap between them. At the same time, the convex strip 303 makes the surface of the roller 3 uneven, increasing the contact area with the arsenic sulfide slag packaging bag. This allows the arsenic sulfide slag packaging bag to move and continue to contact the cutter 102 even with low friction. As the height of the cutter 102 gradually increases, the entire packaging bag is directly split open longitudinally, completely increasing the distance between the packaging bag and the arsenic sulfide slag, so that the arsenic sulfide slag falls directly into the rigid landfill bin below the receiving platform 1.

[0021] Furthermore, as per the instruction manual... Figure 4 As shown, in the second embodiment, a channel is also provided at the bottom of the receiving platform 1. This channel is directly connected to the opening 101 and connected to the rigid landfill below to prevent the arsenic sulfide slag inside the completely opened packaging bag from overflowing to the outside. At the same time, there is another inclined plate behind this embodiment. The inclined plate has the same function as the inclined plate in the first embodiment, which is used to guide the completely cut arsenic sulfide slag packaging bag into the rigid landfill together.

[0022] In use, the receiving platform 1 of this application is placed above the rigid landfill silo, with its tail end aligned with the silo. Then, a hoist or conveyor belt is used to transport the packaging bag containing arsenic sulfide slag to the receiving platform 1. At this time, the guide plate 103 at the front end of the receiving platform 1 is designed to tilt upwards, allowing it to travel at an angle relative to the opening 101. The arsenic sulfide slag packaging bag, under the influence of gravity, slides downwards from the guide plate 103 at its tilt angle onto the opening 101. At this point, a remote start is activated to activate the servo motor, causing its output to be reduced in speed and torque increased by a planetary reducer, which then drives multiple rollers 3 to rotate. When the multiple rollers 3 begin to rotate, according to the attached instruction manual... Figure 1-2It is known that the roller 3 closest to the guide plate 103 is at its highest position relative to the opening 101, but this height is not higher than the thickness of the packaging bag containing arsenic sulfide slag. Therefore, the frictional force generated when the roller 3 closest to the guide plate 103 contacts the arsenic sulfide slag packaging bag pulls it toward the opening 101. At this time, the packaging bag, which is pressed and moved toward the opening 101 by the roller 3, contacts the cutter 102 flush with the opening 101. Due to the weight of the arsenic sulfide slag packaging bag itself and the pressure of the roller 3, it adheres to the cutter 102, and the cutter... The contact area between the cutter 102 and the packaging bag is small, resulting in greater pressure. At this point, the cutter 102 cuts through the arsenic sulfide slag packaging bag. As the arsenic sulfide slag packaging bag continues to be contacted and moved by multiple rollers 3, the height between the multiple rollers 3 and the opening 101 becomes closer and closer. Therefore, the pressure on the arsenic sulfide slag packaging bag is greater as it moves further back from the opening 101, and more of it is pressed down. At this point, the arsenic sulfide slag packaging bag is completely cut open, and then it is moved out of the receiving platform 1 and falls into the rigid landfill by the rollers 3 located behind the opening 101.

[0023] 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.
