Description

Technical Field

[0001] This utility model patent belongs to the technical field of aluminum ash slag treatment equipment, specifically relating to a bag-cutting and feeding device for feeding bagged aluminum ash slag raw materials. Background Technology

[0002] Aluminum ash slag is a common waste product in the aluminum industry, produced in huge quantities. Its main sources are infusible inclusions, oxides, and additives that float on the surface of molten aluminum during the smelting of aluminum and the production of aluminum alloys. Aluminum ash slag contains a certain amount of metallic aluminum, alumina, and other compounds, and has recycling value. To facilitate subsequent processing, aluminum ash slag is currently usually transported in large bags.

[0003] Currently, the feeding process for bagged aluminum ash slag raw materials mainly involves manual unpacking or semi-automatic equipment, which presents the following problems: 1) Manual unpacking is labor-intensive and inefficient; 2) Aluminum ash slag dust is generated seriously during the feeding process, resulting in a harsh working environment; 3) Aluminum ash slag powder often contains unevenly sized lumps or impurities, which will affect the subsequent crushing efficiency if not screened; 4) Waste packaging bags are inconvenient to recycle and dispose of, which can easily cause the workshop to become messy.

[0004] Existing technologies include several feeding devices for bagged materials. For example, CN218704489U discloses a "vibrating screen feeding station capable of automatically cutting open packaging bags," which includes a frame, sub-frame, bag feeding device, unpacking device, dust collection device, unpacking bin, and vibrating screen bin. This device can automatically cut open packaging bags, vibrate for feeding, and extract dust. However, this device is designed for small-scale powder processing plants such as flour and fertilizer plants and cannot meet the requirements of large-scale ore processing equipment in aluminum industry mines. Furthermore, due to the uneven size of aluminum ash slag, it is foreseeable that this device will also be unable to meet the continuous ore processing needs of mines, and its ability to recover dust from aluminum ash slag and screen large pieces is also significantly insufficient.

[0005] Therefore, this paper proposes a bag-cutting and feeding device for feeding bagged aluminum ash slag raw materials. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0020] like Figures 1 to 4 As shown, the existing technology in this embodiment has the following problems: The inventors have found that, currently, the manual unpacking of bagged aluminum ash slag raw materials during the feeding process is labor-intensive and inefficient; aluminum ash slag dust flies seriously during the feeding process, resulting in a harsh working environment; aluminum ash slag powder often contains unevenly sized lumps or impurities, which, if not screened, will affect the subsequent crushing efficiency; the recycling and disposal of waste packaging bags is inconvenient and easily causes problems such as workshop clutter. Existing technologies are mostly designed for small powder processing plants such as flour and fertilizer plants, and cannot meet the requirements of large-scale ore processing equipment required in aluminum industry mines. Moreover, due to the uneven size of aluminum ash slag materials, it is foreseeable that the device cannot meet the continuous ore processing needs of mines, and the recovery of dust from aluminum ash slag powder and the screening of large pieces of material are also significantly insufficient. Therefore, the inventor provides a bag-cutting and feeding device for feeding bagged aluminum ash slag raw materials, including a belt conveyor mechanism 1, a bag-cutting mechanism, a frame A2, a frame B3, a flexible connection structure 5, a screening mechanism 6, a bag removal mechanism, a base 7, a dust collection mechanism, a conveying mechanism (not shown in the figure), and a control cabinet (not shown in the figure). The belt conveyor mechanism 1 is installed on the left side of the inlet of the bag-cutting mechanism. The bag-cutting mechanism is fixedly installed on the left side of the base 7 through the frame A2. The screening mechanism 6 is inclinedly installed on the frame B3 above the base 7 through spring groups 4 fixed around it, and the left side of the screening mechanism 6 is connected to the bag-cutting mechanism through the flexible connection structure 5. The discharge port A8 of the mechanism is connected. The screening mechanism 6 is provided with multiple screening spaces 17, and the bottom of the screening mechanism 6 is provided with discharge ports B18 corresponding to each screening space 17. The bag removal mechanism is installed on the right side of the inner cavity of the screening mechanism 6. The dust collection mechanism is connected to the top of the bag cutting mechanism and the screening mechanism 6 through the shock-absorbing hose 24. The conveying mechanism is located below the discharge port B18. The control cabinet is electrically connected to the belt conveying mechanism 1, the bag cutting mechanism, the screening mechanism 6, the dust collection mechanism, and the conveying mechanism. Its specific control logic can be determined by the user according to the actual situation. The effects and principles below can be referred to in this utility model.

[0021] Its effects and principles are as follows: The device can automatically feed and cut bags through the belt conveyor mechanism 1 and the bag cutting mechanism. It can also screen aluminum ash slag raw materials into fine powder that can be used for fine grinding, coarse particles that can be used for medium grinding, and coarse blocks that can be used for coarse grinding through the screening mechanism 6, and then transport them into the bins respectively, which facilitates subsequent efficient processing. At the same time, the powder that falls into the gap between the blades during the bag cutting process can be collected through the collection trough 15 connected to the screening space 17 on its lower side, avoiding waste. The cut waste bags can be collected by the bag removal mechanism after being separated from the ore by the coarse screen. Some waste bags discharged with the coarse ore can also be quickly removed manually by the conveying mechanism. During the screening process, the dust generated during the bag cutting and screening vibration can be recovered by the dust collection mechanism, reducing the pollution of the air in the production workshop and the impact on the health of personnel. As can be seen from the above, the device has the functions of automatic feeding, bag cutting, screening, conveying and semi-automatic bag removal, which saves labor costs, improves the pretreatment efficiency of aluminum ash slag raw materials, and also reduces the pollution of the environment and the impact on personnel health caused by dust in the whole process.

[0022] Based on the above embodiments, this utility model also provides a bag-cutting mechanism, which includes a receiving bin 9, a drive motor 10, a cutter shaft 11, a receiving plate 12, a cutter groove 13, a bag-cutting circular cutter 14, and a collection groove 15.

The flexible connection structure 5 is connected to the feed inlet of the top screening space 17. The drive motor 10 is installed on the front side of the receiving bin 9 and the drive end is connected to the cutter shaft 11 installed below the receiving plate 12.

The receiving bin 9 is connected to the left feed inlet of the screening mechanism 6 through the flexible connection structure 5. The receiving bin 9 in this structure can receive the raw materials conveyed by the belt conveyor 1. During the receiving process, the drive motor 10 drives the cutter shaft 11 to rotate the bag-cutting circular cutter 14, thereby cutting the bag body of the bagged raw materials sliding up and down the receiving plate 12. The powder falling into the cutter groove 13 during the cutting process can be collected by the collection trough 15 and guided to the middle screening space 17, thereby avoiding the waste of powder.

[0023] Based on the above embodiments, this utility model also provides a screening mechanism 6, on the bottom left side of which an industrial vibration motor 16 is fixedly installed; a large vibration motor of Kunming YZS-8-6 0.55kW model can be selected here, and the specific selection can be configured according to the user's actual application scenario.

[0024] Based on the above embodiments, the present invention also provides a multi-layer screening space 17, which divides the inner cavity of the screening mechanism 6 into three layers of screening space 17 from top to bottom through a coarse-hole screen 20 and a fine-hole screen 21. The bottom of the screening mechanism 6 is provided with three discharge ports B18 corresponding to the three layers of screening space 17 from left to right. A partition 19 is provided between the three discharge ports B18, and the top of the partition 19 is connected to the right end of the coarse-hole screen 20 and the fine-hole screen 21. This structure screens aluminum ash slag raw materials into fine powder that can be used for fine grinding, coarse particles that can be used for medium grinding, and coarse blocks that can be used for coarse grinding, and then conveys them into the silo separately, thereby facilitating subsequent efficient processing.

[0025] Furthermore, a detachable discharge mechanism (not shown in the figure) is installed on the discharge port B18, including a star-shaped discharge valve for discharging powder and granules, and a bar valve for discharging block materials.

[0026] Based on the above embodiments, the present invention also provides a flexible connection structure 5, which is configured as a rubber connection structure; this structure can isolate vibration, reduce noise, and prevent displacement during vibration from damaging the fixedly installed bag cutting mechanism.

[0027] Based on the above embodiments, this utility model also provides a bag removal mechanism, which further includes a bag blocking rod assembly 22 and a bag hook opening 23. The bag blocking rod assembly 22 is located on the lower right side of the coarse mesh screen 20, and the bag hook opening 23 is located on the screening mechanism 6 on the right side of the bag blocking rod assembly 22 with its opening facing the upper right. The design of the bag blocking rod assembly 22 in this structure can facilitate the blocking of the material bag, which can then be hooked out by the worker from the bag hook opening 23. In order to save labor costs, an industrial robotic arm for automatic identification and grasping can be installed here.
