Description

Technical Field

[0001] This utility model relates to the field of coal mine conveyor technology, specifically a dust suppression device for coal mine conveyors. Background Technology

[0002] Coal mine conveyors are indispensable conveying equipment in coal mining. Based on their structure and function, they are mainly divided into two categories: scraper conveyors and belt conveyors. Scraper conveyors, also known as "scraper machines" or "coal chutes," mainly consist of a head section, a middle section, and a tail section. They can transport materials horizontally or at an incline. Some models, such as flexible scraper conveyors, allow bending of 2° to 4° in both horizontal and vertical directions, making them suitable for complex working conditions in underground coal mines.

[0003] When using current coal mine conveyors, the coal being transported generates a lot of dust. Without dust suppression, this will affect the surrounding environment. Traditionally, a water spraying structure is fixedly connected to the side of the conveyor, and installation requires corresponding accessories, making installation inconvenient and unable to meet the needs of remote dust suppression. Simply spraying water is wasteful and cannot effectively suppress dust. Utility Model Content

[0004] The purpose of this utility model is to provide a dust suppression device for coal mine conveyors, in order to solve the problem mentioned in the background art that, when current coal mine conveyors are in use, there is a lot of dust from the coal being transported. Without dust suppression, the surrounding environment will be affected. The traditional method is to fix a water spraying structure to the side of the conveyor, and the installation requires corresponding accessories, which makes the installation inconvenient and cannot meet the needs of remote control dust suppression. Simply spraying water is wasteful of water and cannot comprehensively suppress dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for a coal mine conveyor, comprising a main mounting rod, on which fixed side strips are horizontally and symmetrically welded on both sides; a main pipe is horizontally inserted into one end of the main mounting rod, and a connecting flange is fixedly connected to one end of the main pipe; a transmission line is inserted into one end of the main mounting rod; a snap-fit ​​top groove is horizontally and evenly formed on the top surface of the main mounting rod, and a snap-fit ​​inclined block is snapped into the inner bottom surface of the snap-fit ​​top groove; a vertical side groove is vertically and evenly formed on one side of the main mounting rod, and a toggle block is snapped into the inner side of the vertical side groove; a telescopic upright is vertically connected to the top surface of the main mounting rod, and one side of the telescopic upright is horizontally fixed... A detection host is fixedly installed. A telescopic connecting rod is horizontally fixedly installed on one side of the telescopic pole. A connecting steel pipe is fixedly connected to the bottom surface of the telescopic connecting rod. An auxiliary cylinder is vertically fixedly installed on one side of the telescopic pole. A main connecting plate is horizontally fixedly installed at the bottom end of the connecting steel pipe. Side pipes are symmetrically fixedly installed on both sides of the main connecting plate. Dust suppression nozzles are uniformly fixedly installed on the bottom surface of the main connecting plate. Mist curtain nozzles are uniformly fixedly installed on the bottom surface of the side pipes. A plug pipe is fixedly inserted into the inner end of the snap-fit ​​top groove. A bottom clamping block is fixedly connected to the bottom end of the telescopic pole. One end of the bottom clamping block has a plug-in connection hole. A control valve body is uniformly fixedly installed on the inner side of the mounting main pole.

[0006] Preferably, there are two fixed side strips, and the two fixed side strips are arranged in parallel to each other at the bottom of the two sides of the main rod. One end of the main pipe extends through the end of the main rod and is horizontally set inside.

[0007] Preferably, one end of the transmission line is electrically connected to an external controller, and the extended ends are electrically connected to multiple control valve bodies. There are multiple snap-fit ​​top grooves, which are arranged in parallel and equidistantly on the top surface of the mounting rod. One end of the snap-fit ​​top groove extends through the side wall of the mounting rod to the outside in an open shape.

[0008] Preferably, the snap-fit ​​inclined block is snap-fitted on the inner side of the snap-fit ​​top groove near the opening end, and one side of the snap-fit ​​inclined block is connected to one end of the bottom snap-fit ​​block. The number of vertical side grooves is consistent with the number of snap-fit ​​top grooves, and the extension end of the toggle block is fixedly connected to the side of the snap-fit ​​inclined block.

[0009] Preferably, there are multiple telescopic poles, which are arranged in parallel with each other. The bottom end of the telescopic pole is connected to the top opening of the snap-fit ​​top groove. The detection host adopts a dust detector structure and is electrically connected to the transmission line. One end of the telescopic connecting rod is fixed at the top side of the telescopic pole, and the telescopic connecting rod and the telescopic pole are arranged in an L-shape on the side of the conveyor.

[0010] Preferably, the main connecting plate is horizontally positioned on the top surface of the conveyor, and the interior of the main connecting plate is connected to the interior of the side pipe. One end of the insertion pipe is inserted into the inner side of the insertion hole, and the other end is connected to the control valve body. The bottom end of the bottom clamping block is correspondingly clamped into the inner side of the clamping top groove. Multiple control valve bodies are all connected to the interior of the main pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This dust suppression device for coal mine conveyors features dust suppression nozzles evenly distributed on the bottom surface of the main connecting plate, positioned directly above the top surface of the conveyor. This allows for targeted dust suppression of the coal components on the conveyor. This direct approach to the pollution source ensures the dust suppression liquid fully contacts the coal components, effectively adsorbing and settling dust, significantly improving dust suppression efficiency and reducing dust dispersion during transport. The device connects the main monitoring unit to an external controller via a transmission line, enabling remote intelligent control. The main monitoring unit monitors the dust concentration around the conveyor in real time and transmits the data to the external controller. When the dust concentration exceeds the standard, the external controller automatically opens the corresponding control valve, initiating the dust suppression program. This eliminates the need for manual on-site operation, improving work efficiency, reducing labor costs, and providing timely responses to dust changes, effectively controlling dust pollution. The telescopic pole engages with the mounting main pole via a bottom locking block and a connecting slot, and is then inserted into the connecting pipe and connecting hole. Installation is simple and quick, requiring no complex tools or specialized skills. This snap-fit ​​installation method not only facilitates the installation and disassembly of the equipment but also makes maintenance and repair easier. When a component malfunctions, it can be quickly disassembled and replaced, reducing downtime. The evenly distributed mist curtain nozzles on the bottom surface of the side tubes spray mist curtains, creating an isolation curtain effect on both sides of the conveyor. The mist curtains effectively prevent dust generated by the conveyor from spreading outwards, keeping dust within a certain range, reducing dust pollution to the surrounding environment, protecting the health of workers, and meeting environmental protection requirements.
