Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, and more specifically, it relates to a coal mine belt conveyor with slag removal function. Background Technology

[0002] In the field of coal mining and transportation, belt conveyors are a commonly used material conveying equipment, widely used in various stages of coal transportation from underground to above ground to facilitate the transfer of coal resources. During coal transportation, there is continuous friction and compression between the coal and the belt, causing coal slag particles to adhere to the belt surface. If the coal slag is not removed in time, it will easily cause accelerated belt wear and shorten the belt's service life. However, traditional slag removal devices, relying solely on simple scrapers, are insufficient to completely remove sticky coal slag. At the same time, the scraper generates heat from prolonged contact with the belt, leading to accelerated scraper aging and increased equipment operating costs. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a coal mine belt conveyor with slag removal function, thereby solving the technical problem that traditional slag removal devices, relying solely on simple scrapers, cannot thoroughly remove sticky coal slag in the prior art.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5As shown, this utility model provides a coal mine belt conveyor with a slag-removing function, including a belt drive device 11 and a belt 12. The belt 12 is mounted on the belt drive device 11, enabling coal transportation. A mounting bracket 13 is provided on one side of the belt drive device 11, and a slag-removing assembly is mounted on the mounting bracket 13. The slag-removing assembly includes a scraper 14 and a water supply plate 15. The water supply plate 15 is mounted on the mounting bracket 13, and the scraper 14 is mounted on the water supply plate 15, contacting the belt 12. The water supply plate 15 provides mounting support for the scraper 14 and a mounting base for components such as the water spray nozzle 16. The scraper 14 effectively removes residual coal slag from the belt 12, improving the device's ability to clean the surface of the belt 12 and ensuring the normal operation of the belt 12 and the efficiency of coal transportation. A water spray nozzle 16 is provided on one side of the water supply plate 15. The water spray nozzle 16 is connected to an external water source pipe through the water supply plate 15. The water spray nozzle 16 sprays water onto the surface of the conveyor belt 12 to moisten the coal slag, making it easier for the scraper 14 to remove it. It also serves to reduce dust and cool the surface, extending the service life of the device. Below the water supply plate 15 is a water circulation component for filtering coal-containing wastewater. This water circulation component filters the coal-containing wastewater, enabling water recycling, reducing water waste, and improving the water utilization efficiency and environmental performance of the device.

[0025] like Figures 2 to 5 As shown, a sliding groove is provided on the water supply plate 15, and the scraper 14 is slidably disposed in the sliding groove. End caps 18 are detachably provided at both ends of the sliding groove. The sliding groove and end caps 18 facilitate the installation and removal of the scraper 14, making it easy to replace and maintain the scraper 14. At the same time, they also ensure the sliding stability of the scraper 14 in the sliding groove, thereby improving the maintainability and performance of the slag removal component of the device.

[0026] The water supply plate 15 is equipped with a cooling pipe 17. One end of the cooling pipe 17 is connected to the water spray outlet 16 pipe, and the other end is connected to an external water source pipe. Multiple nozzles are evenly distributed along the width of the belt 12 on the water spray outlet 16. The cooling pipe 17 cools the water entering the water spray outlet 16, preventing excessively high water temperatures from affecting the spraying and dust suppression effects. It also provides some cooling for the scraper 14, improving the working performance and stability of the slag removal components. The multiple nozzles ensure that water is sprayed onto the surface of the belt 12, enhancing the slag removal and dust suppression effects and improving the slag removal and environmental performance of the device.

[0027] The mounting bracket 13 is equipped with a guide plate 19, which is inclinedly positioned below the scraper 14, with its lower end facing the water circulation component. The guide plate 19 guides the coal slag and wastewater scraped off by the scraper 14 into the water circulation component, facilitating the collection and treatment of the coal slag and wastewater and improving the efficiency of the device's slag removal and wastewater treatment.

[0028] like Figure 2 , 4 As shown in Figure 5, the water circulation assembly includes a slag collection box 21, which is located directly below the scraper 14. This location allows the slag collection box 21 to collect the coal slag and wastewater scraped off by the scraper 14, improving the collection efficiency of the device. The slag collection box 21 contains a filter layer 22, which divides it into a slag discharge chamber and a wastewater chamber. The filter layer 22 allows for preliminary filtration of the coal-containing wastewater, leaving the coal slag in the slag discharge chamber and allowing the filtered wastewater to flow into the wastewater chamber. This facilitates separate treatment of the coal slag and wastewater, improving the device's wastewater treatment capacity and effectiveness.

[0029] A slag discharge rod 23 is installed inside the slag discharge chamber, and a drive motor 24 is installed on one side of the slag collection box 21. The output shaft of the drive motor 24 is connected to one end of the slag discharge rod 23. Through the arrangement of the slag discharge rod 23 and the drive motor 24, the coal slag in the slag discharge chamber can be pushed into the slag discharge pipe 25 to achieve the discharge of coal slag. The slag collection box 21 is equipped with a slag discharge pipe 25, and the other end of the slag discharge rod 23 extends into the slag discharge pipe 25. The slag discharge pipe 25 is connected to external waste slag treatment equipment. Through the arrangement of the slag discharge pipe 25, the coal slag pushed out by the slag discharge rod 23 can be transported to the external waste slag treatment equipment for processing, ensuring the proper disposal of coal slag.

[0030] The slag collection box 21 is equipped with a drain outlet 26, and a cyclone separator 27 and a water pump 28 are located at the other end of the slag collection box 21. The drain outlet 26 is connected to the inlet of the cyclone separator 27 through the water pump 28, and the outlet of the cyclone separator 27 is connected to an external water source pipeline. The waste slag outlet of the cyclone separator 27 is connected to waste slag treatment equipment. Through the cyclone separator 27, the sewage in the wastewater chamber can be further separated, removing fine particles and impurities, so that the treated water meets the standards for recycling. Simultaneously, the separated waste slag is transported to the waste slag treatment equipment for further processing, improving the quality of sewage treatment and the efficiency of water resource recycling. During this process, the water pump 28 pumps the sewage from the slag collection box 21 into the cyclone separator 27. This water pump 28 can be a sewage pump.

[0031] The specific usage and function of this embodiment are as follows:

[0032] During the operation of the coal mine belt conveyor, the belt drive device 11 drives the belt 12 to rotate and transport coal. When the belt 12 passes the slag removal assembly, the water spray nozzle 16 sprays water onto the surface of the belt 12 through the nozzle to moisten the coal slag on the belt 12. At the same time, the cooling pipe 17 cools the scraper 14 to ensure the cleaning effect. The scraper 14 contacts the belt 12 and scrapes off the moistened coal slag. The scraped coal slag and wastewater flow into the slag collection box 21 under the guidance of the guide plate 19. In the slag collection box 21, the filter layer 22 performs preliminary filtration of the coal-containing wastewater. The coal slag remains in the slag discharge chamber, and the wastewater flows into the wastewater chamber. The drive motor 24 drives the slag discharge rod 23 to rotate, pushing the coal slag in the slag discharge chamber to the slag discharge pipe 25, and then transporting it to the external waste slag treatment equipment for processing. Wastewater in the wastewater chamber enters the cyclone separator 27 through the drain outlet 26. The cyclone separator 27 further separates and treats the wastewater. The treated water flows back to the external water source pipeline through the outlet and can be reused for spraying water at the spray outlet 16. The separated waste residue is transported to the waste residue treatment equipment for processing through the waste residue outlet. Through the above process, the slag removal function of the coal mine belt conveyor and the recycling of water resources are realized, ensuring the normal operation of the belt 12 and the efficiency of coal transportation, while also improving environmental performance.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
