[0019] See Figures 1-4 This utility model is a multifunctional negative pressure dust collection and cleaning device, including a main pipe 1, which is connected and fixed to the right side of a bag dust collector 2. Several branch pipes 3 are connected and fixed to the rear side of the main pipe 1. Several interfaces 4 are connected and fixed to the bottom surface of the main pipe 1. Pneumatic butterfly valves 5 are provided on the interfaces 4 and the branch pipes 3. Flexible hoses 6 are detachably installed at the bottom of the interfaces 4. Vacuum cleaners 7 are fixed at the bottom of the flexible hoses 6. A mounting base 8 is fixed to the front side of the bag dust collector 2. A conveyor belt 9 is provided inside the mounting base 8. A dust hopper 10 is fixed to the bottom of the bag dust collector 2. A dust discharge valve 11 is provided at the discharge end of the dust hopper 10. A PLC controller 12 is fixed to the front side of the mounting base 8. The PLC controller 12 is a Siemens S7-200. The pneumatic butterfly valves 5 and the dust discharge valve 11 are electrically connected to the PLC controller 12.

[0020] In this embodiment, a dust collection hood 13 is fixed to the bottom end of several of the branch pipes 3.

[0021] In this embodiment, the outlet end of the ash discharge valve 11 is fixed with a sloping groove 14, the bottom surface of the sloping groove 14 is connected to the top surface of the mounting base 8, and the inner bottom surface of the sloping groove 14 is a sloping surface.

[0022] In this embodiment, a first flange 15 is fixed to the bottom of several interfaces 4, and a second flange 16 is fixed to the top of several hoses 6. The second flanges 16 and the first flanges 15 are connected by bolts.

[0023] In this embodiment, a sealing ring 17 is provided between several first flanges 15 and several second flanges 16.

[0024] In this embodiment, a blocking cover 18 is fixed on the top surface of the mounting base 8, and the blocking cover 18 has a through hole on its rear side.

[0025] In use, several interfaces are evenly distributed on the main pipe, with one set at regular intervals (e.g., ten meters). Several branch pipes extend into key dust-generating points in the concentrate storage area, such as the weighbridge and batching area. When workers need to collect dust generated during concentrate batching and unloading operations, they simply close the pneumatic butterfly valves on several interfaces and open the pneumatic butterfly valves on several branch pipes via the PLC controller. Then, the bag filter dust collector is started. The strong negative pressure generated inside the bag filter dust collector quickly and efficiently draws the dust generated during concentrate batching and unloading into the main pipe through several branch pipes. The dust is then transported to the bag filter dust collector. After being filtered by the bag filter dust collector, the collected dust is enriched in the ash hopper. At this point, by opening the ash discharge valve, the dust can be directly discharged onto the conveyor belt and transported to the smelting furnace along with the material. This process effectively avoids secondary dust generation during the transfer process, realizes closed-loop recycling of copper concentrate dust, and improves the working environment.

[0026] When workers need to clean the conveyor belt corridor, the operation is equally simple. Just reliably connect the vacuum cleaner to the interface through the hose. The vacuum cleaner can be handheld or trolley type according to actual needs. After the connection is completed, close the pneumatic butterfly valves on several branch pipes through the PLC controller, and open the pneumatic butterfly valves on several interfaces at the same time. Then start the bag dust collector to generate negative pressure, so that the vacuum cleaner can generate strong suction force to clean the dust deposited on the floor and equipment of the conveyor belt corridor. The dust is allowed to enter the bag dust collector smoothly, and then discharged directly onto the conveyor belt through the ash hopper and the ash discharge valve.

[0027] Through the coordinated operation of the main pipe, bag filter, branch pipe, interface, pneumatic butterfly valve, hose, vacuum cleaner, mounting base, conveyor belt, ash hopper, ash discharge valve and PLC controller, a single device can simultaneously meet the needs of fixed dust collection points in the concentrate silo and dust collection and cleaning of the conveyor belt corridor, improving equipment utilization, reducing equipment costs, and enhancing work efficiency and cleaning effect.

[0028] In use, the dust collection hood can effectively expand the dust collection range and collect the dust around the dust-generating point more comprehensively. When dust is generated during operations such as batching and unloading in the concentrate silo, the dust collection hood acts like a huge "dust suction port", quickly sucking the dust into the branch pipe and then transporting it to the bag dust collector for treatment. This improves dust collection efficiency, reduces the diffusion of dust in the air, and effectively improves the quality of the working environment.

[0029] During operation, after the ash discharge valve directly releases the dust, the dust accurately enters the chute. The chute provides a clear direction for dust transport. Because the bottom of the chute is designed as an incline, the dust, under the influence of gravity, slides naturally and smoothly down the incline and ultimately lands accurately on the conveyor belt. This ensures that the dust is accurately transported to the designated location, further improving the overall efficiency and accuracy of dust handling. When it is necessary to disassemble or assemble the hose and vacuum cleaner, the operator only needs to connect or separate the second flange from the first flange using bolts, facilitating equipment maintenance and replacement.

[0030] During operation, when the first flange and the second flange are bolted together, the sealing ring is tightly compressed between them, forming a reliable sealing barrier. This barrier effectively prevents dust and air from leaking out of the connection, ensuring the airtightness of the entire dust collection system. When materials and dust are conveyed on the conveyor belt, the baffle effectively prevents them from escaping due to various reasons (such as airflow, vibration, etc.), reducing dust pollution to surrounding equipment and the environment.
