Description

Technical Field

[0001] The present application relates to the technical field of mineral material dust reduction equipment, and in particular to a mineral material dust reduction device in a mine bin. Background Art

[0002] In a smelter, there are usually multiple silos for temporary storage of ore materials. When in use, the ore materials are usually transported by trucks, usually by cranes with grab buckets or loaders. In this process, a large amount of dust will be generated, which will pollute the working environment. Working in such an environment for a long time is likely to cause damage to the health and safety of the workers. In addition, when flammable ore materials such as coal are piled up in large quantities, they are prone to spontaneous combustion when encountering a hot and dry climate, which poses a major safety hazard. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related technology, the present application provides a dust reduction device for mineral materials in a mine bin. The device can switch between spray humidification and spray dust suppression at any time according to usage requirements, thereby reducing mineral dust and ensuring the safe stacking of flammable mineral materials.

[0004] The present application provides a dust reduction device for mineral materials in a mine bin, comprising a water inlet pipe, a water pump, a main pipe, a branch pipe, a control valve, a reversing valve, a first pipeline, a second pipeline, a spray head, and an atomizing nozzle. The water inlet pipe is equipped with a water pump, and the end of the water inlet pipe is connected to the branch pipe through the main pipe. The branch pipe is equipped with a control valve for controlling the on-off of the pipeline, and the end of the branch pipe is equipped with a reversing valve. Two water outlets of the reversing valve are respectively connected to the first pipeline and the second pipeline. A plurality of groups of spray heads for humidifying mineral materials are evenly installed on the top of the first pipeline, and a plurality of groups of atomizing nozzles for dust reduction are evenly installed on the top of the second pipeline.

[0005] Optionally, in some embodiments, one end of the water inlet pipe is connected to the water supply tank, and the other end is connected to two main pipes respectively through a three-way pipe connector.

[0006] Optionally, in some embodiments, a plurality of branch pipes are evenly installed on the main pipe.

[0007] Optionally, in some embodiments, an overflow valve is installed on the water inlet pipe, and the overflow valve is connected to the water supply tank through a return pipe.

[0008] Optionally, in some embodiments, a stop valve for cutting off the water supply is also installed on the water inlet pipe.

[0009] The technical solution provided by this application may have the following beneficial effects:

[0010] The present application sets a first pipe and a second pipe. The first pipe sprays a larger water flow rate for spraying and humidification, and the second pipe sprays a smaller water flow rate for spraying and dust suppression. The two modes can be switched at any time through a reversing valve, which is convenient and practical. In addition, by setting a control valve on each branch pipe, targeted spraying can be performed according to the stacking situation of the mineral materials in the ore bin, thereby reducing the consumption of water resources.

[0021] See also Figure 1-2 The dust suppression device for mineral materials in the ore bin comprises a water inlet pipe 2, a water pump 3, a main pipe 8, a branch pipe 9, a control valve 10, a reversing valve 11, a first pipeline 12, a second pipeline 13, a sprinkler head 14, and an atomizing nozzle 15. One end of the water inlet pipe 2 is connected to a water supply tank 1, and the other end is provided with a three-way pipe connector 7. The water inlet pipe 2 is provided with a water pump 3, an overflow valve 4, and a stop valve 6 in sequence. The water pump 3 is used to supply water to the pipeline of the device, and the stability of the water pressure in the pipeline is ensured; the overflow valve 4 is provided with a return pipe 5 connected to the water supply tank 1. When the water pressure in the water inlet pipe 2 is too high, the return pipe 5 is connected to the water supply tank 1. When the overflow valve 4 opens under the action of water pressure, part of the water flows back to the water supply tank 1 along the return pipe 5 to prevent the water inlet pipe 2 from rupture due to excessive water pressure, thereby ensuring the safety of the pipeline; since the mine is usually built on the mountain, the location of the water supply tank 1 may be higher than the location of the mine bin. At this time, there is natural water pressure in the water supply pipe 2 due to the height difference. In this case, the water inlet pipe 2 will be filled with water and is always in a water supply state. The water supply of the water inlet pipe 2 can be cut off by the stop valve 6, so as to facilitate the maintenance and replacement of subsequent pipelines such as the main pipe 8 and the branch pipe 9.

[0022] The ends of the water inlet pipe 2 are connected to the two main pipes 8 respectively through the three-way pipe connector 7. The water supply position of the water inlet pipe 2 is located in the middle of the two main pipes 8 through the three-way pipe connector 7 to avoid the water supply distance being too long, thereby ensuring the stability of the water pressure. Furthermore, in order to improve the stability of the water pressure at the main pipe 8, the diameter of the main pipe 8 is smaller than the diameter of the water inlet pipe 2.

[0023] The length of the main pipe 8 is about half the width of the ore bin. According to the dust reduction demand in the ore bin, multiple branch pipes 9 are evenly installed on the main pipe 8. The higher the dust reduction demand, the greater the density of the branch pipes 9. The distance between two adjacent branch pipes 9 is usually between 5 and 10 meters. A control valve 10 for controlling the on-off of the pipeline is installed on the branch pipe 9. The on-off of a single branch pipe 9 can be controlled by the control valve 10. In the process of humidification and dust reduction, only the branch pipe 9 in the area where the mineral materials are stacked can be opened, so as to carry out targeted humidification and dust reduction and reduce the consumption of water resources.

[0024] See also Figure 2 A reversing valve 11 is installed at the end of the branch pipe 9, and the two water outlets of the reversing valve 11 are respectively connected to the first pipe 12 and the second pipe 13. The first pipe 12 extends vertically along the side wall of the ore bin, extends to the top of the ore bin and then extends horizontally to cover the entire ore bin area. A plurality of groups of spray heads 14 are evenly installed on the top of the first pipe 12. The number of spray heads 14 installed is adjusted according to the humidification and dust reduction requirements of the ore bin. The spray head 14 sprays a large amount of water, which is used to humidify the mineral material, thereby reducing the dust generated during the transportation of the mineral material and reducing the risk of spontaneous combustion of the flammable mineral material; the second pipe 13 is arranged in parallel with the first pipe 12, and a plurality of groups of atomizing nozzles 15 are evenly installed on the top thereof. The water output of the atomizing nozzle 15 is small and is only used to suppress a small amount of dust generated during normal production. Two different nozzles are set because, due to the large water output of the spray head 14, there is a risk of workers getting wet during the spray humidification process, which is inconvenient for production activities, while the atomizing nozzle 15 has a small water output and will not affect the normal production activities of the workers. After the spray head 14 stops, a small amount of dust in the mine bin can be suppressed, thereby reducing the generation of dust in the mine bin and ensuring the health and safety of the workers.

[0025] Furthermore, in order to improve the convenience of humidification and dust reduction control, the control valve 10 and the reversing valve 11 are remotely controllable models and are electrically connected to the PLC, so as to realize remote control of humidification and dust reduction in the mine bin through the PLC.

[0026] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
