Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust suppression technology for tippers, and in particular to a closed dry fog dust suppression system for bulk material tippers. Background Technology
[0002] The existing tippler system has an open structure between the hopper and the tippler body during operation. Due to the material properties and the impact airflow generated by the discharge drop, a large amount of dust is inevitably generated during unloading. During operation, a significant amount of dust, including some combined with water, disperses and settles in the open space on the second floor of the tippler, causing substantial dust accumulation on the second-floor floor and the surfaces of associated cables and auxiliary equipment. This poses a significant fire hazard and serious safety risks, severely impacting equipment operation safety and the on-site working environment. Furthermore, the dust requires regular manual cleaning, leading to secondary health hazards and secondary dust generation. Therefore, from the perspectives of green port construction, personnel health, and equipment operation safety, a fundamental solution is essential. The increased cleaning workload necessitates a complete resolution. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a closed dry fog dust suppression system for bulk material tippers, which aims to improve the problem that previous tippers could not significantly achieve dust suppression and effective dust isolation during tipper operation.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A closed-loop dry fog dust suppression system for a bulk material tipper includes a tipper body, a spray box, a dry fog dust suppression system body, a closed dust-blocking chamber for the upper cable, a closed dust-blocking wall, a ground base, and a second-layer unloading hopper base. The dry fog dust suppression system body is located above the spray box, and a spraying system is installed inside the spray box. A support rod is fixedly connected to the outer wall of the closed dust-blocking wall, which is located outside the closed dust-blocking chamber for the upper cable. A second-layer cable tray is installed on the right side of the closed dust-blocking chamber for the upper cable. A unloading funnel is fixedly connected inside the second-layer unloading hopper base. The closed dust-blocking wall is located below the ground base, and a cable body is installed inside the closed dust-blocking wall. A first-layer cable tray is installed below the cable body. A rotating assembly is installed inside the tipper body for unloading materials.
[0006] Preferably, the unloading assembly includes a tipper rotor, the outer wall fixing block of the tipper rotor is connected to the inside of the tipper body, the output end of the tipper rotor is fixedly connected to the car body to be unloaded, an integrated enclosed steel dust barrier device is designed and installed between the second-layer unloading hopper of the tipper body and the bottom surface of the top concrete foundation, and an enclosed isolation room is designed in the tipper upper area.
[0007] Preferably, all gaps at the connection points between the enclosed dust barrier wall, the enclosed dust barrier chamber for the upper cable, the tipper body, and the civil engineering foundation are sealed with sealant a second time.
[0008] Preferably, the dry fog dust removal system mainly consists of a micron-level dry fog dust suppressor, an air compressor, an air tank, a sprayer assembly, a water-air connection pipeline, and an electric heat tracing system.
[0009] Preferably, the tipper body consists of the car body to be unloaded and the tipper rotor.
[0010] Preferably, the enclosed dust barrier is located between the ground base and the unloading hopper.

[0012] Preferably, the working area of the tipper body is designed with a micron-level dry fog dust suppression system around it, and angle-adjustable dry fog dust removal boxes are installed to form a full coverage of the dry fog dust suppression area.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, without changing the original main structure of the tipper, by adding a second-layer sloping enclosed dust barrier wall and an upper-level cable device, the cable and auxiliary ground area of the second layer area are effectively isolated from the tipper's working material dropping area, so that the settled coal dust slides directly into the hopper, thereby significantly achieving dust suppression and effective dust isolation during tipper operation, and thus achieving effective dust removal.
[0015] 2. In this utility model, the closed dust barrier is an extension of the lower unloading hopper. The inclined setting has the function of gathering dust, reducing the spread of dust, and at the same time protecting the second-layer electrical equipment from pollution, keeping the electrical equipment clean and operating normally, thereby extending the service life of the equipment, reducing maintenance costs, including improving dust removal efficiency.
[0016] 3. This utility model employs dry fog dust suppression technology, significantly reducing water consumption for dust suppression and effectively inhibiting inhalable particles, minimizing their harm to the human body. The micron-level dry fog dust removal device primarily suppresses inhalable particles smaller than 150μm. This system features heat preservation and heat tracing functions, and the generated dry fog has minimal impact on the operation of tippers in low-temperature winter conditions. It solves the problem of raw water dust removal devices being unusable in low-temperature winter conditions in northern regions, successfully achieving effective dust suppression around the clock, and taking a crucial step towards building a "green port" for bulk cargo terminals.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-2A closed-loop dry fog dust suppression system for a bulk material tipper includes a tipper body 15, a spray box 3, a dry fog dust suppression system body 4, a closed-loop dustproof chamber for the upper cable 5, a closed-loop dustproof wall 8, a ground base 13, and a second-layer unloading hopper base 14. The dry fog dust suppression system body 4 is located above the spray box 3. A spray system 10 is installed inside the spray box 3. Support rods 16 are fixedly connected to the outer wall of the closed-loop dustproof wall 8. The closed-loop dustproof wall 8 is located at the upper cable closed-loop dustproof chamber. Outside chamber 5, on the right side of the enclosed dustproof chamber 5 for the upper cable, there is a second-layer cable tray 6. Inside the second-layer unloading hopper base 14, there is a fixed unloading hopper 7. Inside the unloading hopper 7, there is dust 9. The enclosed dustproof wall 8 is located below the ground base 13. Inside the enclosed dustproof wall 8, there is a cable body 11. Below the cable body 11, there is a first-layer cable tray 12. Inside the tipper body 15, there is a rotating component. The rotating component is used for unloading.
[0024] Specifically, the support rod 16 serves to support and fix the enclosed dust barrier 8, with dust 9 located inside the unloading hopper 7. A micron-level dry fog dust suppression system is designed around the working area of the three-tumbler, and angle-adjustable dry fog dust collection boxes are installed. The dry fog dust suppression device mainly consists of a micron-level dry fog dust suppressor, an air compressor, an air tank, a sprayer assembly, water-air connection pipelines, and an electric heating system. It utilizes an electronic control system to achieve online automatic dust suppression. The micron-level dry fog dust suppression device uses a compressed air-driven acoustic oscillator to highly atomize water through high-frequency sound waves. The compressed airflow sprays water mist particles in a soft, low-speed mist form through the nozzle resonance chamber to the dust 9 generation point. The dust 9 aggregates and falls, causing the dust particles to adhere to each other, increase in size, and settle under their own gravity, achieving effective dust suppression. Simultaneously, the system features heat preservation and heating; manual and fully automatic control modes; and purging, drainage, and antifreeze functions.
[0025] Reference Figure 1 and Figure 2 The unloading assembly includes a tipper rotor 2. The outer wall fixing block of the tipper rotor 2 is connected to the inside of the tipper body 15. The output end of the tipper rotor 2 is fixedly connected to the car body 1 to be unloaded. An integrated enclosed steel dustproof wall device is designed and installed between the second-layer unloading hopper 7 of the tipper body 15 and the bottom surface of the top concrete foundation. An enclosed isolation room is designed in the tipper machine area.
[0026] Specifically, an integrated enclosed steel dust barrier was designed and installed between the guide plates around the upper perimeter of the second-level unloading hopper 7 of the tippler and the bottom surface of the top concrete foundation. Several inclined support rods were added to the outside of the inclined dust barrier to ensure its overall stability. An enclosed isolation chamber was designed and installed in the cable handling area between the top and second-level floors of the tippler, forming an integrated enclosed structure with the dust barrier, effectively isolating the tippler body from the second-level area. The isolation chamber is equipped with a maintenance door with a sealing strip, facilitating personnel access for routine cable maintenance and internal dust cleaning.
[0027] Reference Figure 1 and Figure 3 All gaps at the connection points between the enclosed dust barrier wall 8, the enclosed dust barrier chamber 5 for the upper cable, the tipper body 15, and the civil engineering foundation have been sealed with sealant a second time. The dry fog dust suppression system body 4 mainly consists of a micron-level dry fog dust suppressor, an air compressor, an air tank, a sprayer assembly, a water-air connection pipeline, and an electric heating system. The tipper body 15 consists of the unloading car body 1 and the tipper rotor 2. The enclosed dust barrier wall 8 is located between the ground base 13 and the unloading hopper 7. The dry fog dust suppression system body 4 is located around the top rectangular unloading area. The working area of the tipper body 15 is designed with a micron-level dry fog dust suppression system, and adjustable-angle dry fog dust suppression boxes are installed to form a full coverage of the dry fog dust suppression area.
[0028] Specifically, the micron-level dry fog dust suppression machine is the control center of the entire dry fog dust suppression system. It is responsible for controlling the start and stop of the high-pressure water and high-pressure air circuits, as well as operations such as filtration and backwashing. The air compressor provides compressed air to the dry fog dust suppression system and is an important power source for generating dry fog. The air storage tank is a device specifically used to store gas, ensuring that the dry fog unit can obtain sufficient compressed air when needed. The sprayer assembly is the core equipment of the dry fog dust suppression system, responsible for mixing water and compressed air and atomizing them into micron-level dry fog particles. The water-air connection pipeline connects the various devices of the micron-level dry fog dust suppression system with pipes of different diameters, ensuring that water and compressed air can be smoothly delivered to the sprayer assembly. The electric heating system is used for protection against... The dry fog dust suppression device freezes under low temperature conditions to ensure continuous and stable operation. All gaps in the dust barrier wall, including the connection between the tipper rollers and the dust barrier wall, and the connection between the dust barrier wall and the concrete foundation, are sealed with sealant to achieve secondary sealing. An integrated enclosed steel dust barrier wall device is designed and installed between the guide plates around the upper part of the tipper's second-layer grating and the bottom surface of the concrete foundation of the top discharge port. By adding a second-layer sloping enclosed coal barrier wall device to the tipper's upper cable area, an enclosed isolation chamber is designed, forming an integrated enclosed structure with the dust barrier wall. This effectively isolates the cables and auxiliary ground area of the second-layer area from the tipper's working material dropping area, allowing the settled coal dust to slide directly into the hopper.
[0029] Working Principle: When this dry fog dust suppression system is needed, a micron-level dry fog dust suppression system is designed around the working area of the three-tiered tippler, and angle-adjustable dry fog dust collection boxes are installed. The micron-level dry fog dust suppression device is a sonic oscillator driven by compressed air. It atomizes water to a high degree through high-frequency sound waves, thereby forming a large number of water mist particles. This can significantly achieve dust suppression and effective isolation of dust particles during tippler operation. The maximum overflow of dust particles was detected by suspending water buckets. The guide plates around the upper perimeter of the second-layer grid grate of the tippler and the top unloading plate are located at the top. An integrated enclosed steel dust barrier device is designed and installed between the bottom surface of the concrete foundation of the material outlet. By adding a second-layer sloping enclosed coal retaining wall device for the tipper, an enclosed isolation chamber is designed in the cable area of the tipper, forming an integrated enclosed structure with the dust barrier. This effectively isolates the cables and auxiliary ground area of the second layer from the working material dropping area of the tipper, allowing the settled coal dust to slide directly into the hopper. The enclosed dust barrier 8 is an extension of the lower unloading hopper 7, and its inclined setting has the function of collecting dust, while also protecting the electrical equipment on the second layer from contamination.
