Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a negative pressure dust collection device for floor cleaning. Background Technology

[0002] In recent years, with the changing environmental situation, the country has gradually raised its environmental protection requirements for fugitive emissions, and the management regulations have been continuously refined. In the field of industrial production, the problem of scattered and accumulated materials urgently needs to be solved.

[0003] In steel, coal, and chemical enterprises, belt conveyors are common material transportation equipment. In the coal and coke conveying corridors of belt conveyors, as well as at and near the bottom of the belt, there are often large amounts of coal, coke powder, coke lumps and other materials scattered and piled up. During the operation of the belt, these scattered materials will cause dust to varying degrees, which not only pollutes the surrounding environment, but also affects the stable operation of the equipment.

[0004] Currently, the main method for addressing the problem of scattered and accumulated materials is traditional manual sweeping. However, this method easily generates secondary dust during the sweeping process, failing to effectively solve the dust pollution problem. While using water washing to suppress dust can reduce dust to some extent, it can lead to corrosion of the conveyor belt frame, affecting the safety of operating equipment, and cannot fundamentally solve the actual problem of large-scale scattered materials.

[0005] Traditional cleaning methods not only fail to meet environmental protection requirements but also lead to material waste and increased production costs for enterprises. Manual cleaning is inefficient, labor-intensive, and operates in harsh environments, hindering efficient production and sustainable development. Existing cleaning equipment is not adequately designed to integrate with conveyor belt corridor layouts, failing to achieve comprehensive, thorough cleaning. Furthermore, it lacks sufficient features in material recycling, automatic discharge, and equipment protection, making it difficult to effectively address the problems caused by material spillage in industrial production. Therefore, there is an urgent need to improve upon existing floor cleaning negative pressure dust collection devices to solve these issues. Utility Model Content

[0006] The purpose of this invention is to provide a negative pressure dust collection device for floor cleaning to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure dust collection device for floor cleaning, comprising a dust filter host, a mounting bracket fixedly installed at the bottom of the dust filter host, an exhaust main pipe fixedly installed at the top of the dust filter host, the exhaust main pipe fixedly installed on an exhaust branch pipe, and the other end of the exhaust branch pipe fixedly installed on a secondary filter device; the negative pressure dust collection device for floor cleaning includes a dust filter host, a dust recovery main pipe fixedly installed at the bottom of the dust filter host, a cleaning valve fixedly installed at the end of the dust recovery main pipe, and multiple sets of dust recovery branch pipes fixedly installed on the dust recovery main pipe, the distance between the dust recovery branch pipes being 25-30 meters.

[0008] Preferably, a dust collection valve is fixedly installed at the end of the dust collection branch pipe, a dust collection hose is fixedly installed on the other side of the dust collection valve, and a dust collection hood is fixedly installed at the other end of the dust collection hose.

[0009] Preferably, the recycling filtration mechanism includes a dust filter host, and a pressure relief valve is fixedly installed on the side of the dust filter host. The detection end of the pressure relief valve is installed inside the dust filter host. When the equipment is stopped, it effectively prevents the vacuum negative pressure inside the pipeline from impacting the vacuum pump rotor and avoids damage to the equipment.

[0010] Preferably, a controller is fixedly installed below the pressure relief valve, the bottom of the dust filter host is tapered, a connecting pipe is fixedly installed at the bottom of the dust filter host, the other end of the connecting pipe is fixedly installed on the vacuum pump, the connecting pipe passes through the filter, and the controller is controlled by a touch screen PLC program.

[0011] Preferably, an exhaust pipe is fixedly installed on the top of the dust filter host, and one end of the exhaust pipe passes through the dust filter host and is fixedly installed at the exhaust port of the vacuum pump.

[0012] Preferably, the other end of the main exhaust pipe is fixedly installed on the branch exhaust pipe, the other end of the branch exhaust pipe is fixedly installed on the secondary filter device, the secondary filter device is equipped with a flow channel fan, and the exhaust port of the secondary filter device is fixedly installed with an exhaust pipe.

[0013] Preferably, a filter plate is fixedly installed inside the dust filtration host. The filter plate is installed at an angle inside the dust filtration host. The filter plate is provided with multiple sets of filter holes. The angle of inclination of the filter plate is 45°. The filter plate is located below the dust recovery main pipe. The lowest end of the filter plate is provided with a discharge port. A control valve is fixedly installed on the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This negative pressure dust collection device for ground cleaning, combined with a rationally designed pipeline network in conjunction with the conveyor belt corridor layout, enables comprehensive and thorough cleaning without blind spots. Coal dust, coke dust, and other materials scattered in the conveyor belt corridor can be effectively collected. The collected dust or materials can be transported to designated silos or directly to the nearest conveyor belt for reuse in the production process. This not only avoids material waste but also improves resource recycling rates, reduces production costs, and creates additional economic benefits for the enterprise. It allows previously scattered and useless materials to regain value, promoting a highly efficient cycle in the production process.

[0016] 2. This negative pressure dust collection device for ground cleaning automatically removes collected materials through a vacuum pump and airflow pipeline. The intelligent material recovery device operates continuously during discharge and can be automatically controlled via PLC. This significantly improves the environment of the conveyor belt corridor, effectively solving the problem of fugitive emissions. Personnel no longer need to manually clean large amounts of scattered materials and dust, reducing labor intensity and creating a safer and healthier working environment, while also improving work efficiency. Furthermore, the pressure relief valve design effectively prevents the vacuum pump rotor from being impacted by the internal vacuum pressure of the pipeline when the equipment stops, thus avoiding equipment damage.

[0027] Example 2:

[0028] Based on Example 1, there are shortcomings in material recycling, automatic material discharge, and equipment protection, resulting in resource waste.

The discharged gas is then transported to the secondary filtration device 5 through the outlet main pipe 3 and the outlet branch pipe 4. After being filtered by the secondary filtration device 5 and the flow channel fan, the gas is finally discharged from the equipment through the outlet pipe 17, so that the discharged gas meets the emission standards.
