Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor cleaners, in particular to a cleaner used for a coal washing belt conveyor. Background Art

[0002] Coal washing refers to the process of separating the mined coal into different grades with different components and specific gravity through the impact of water flow, and removing dust and waste rock to obtain clean coal. When washing coal, the coal blocks need to be transported to the coal washing pool by a belt conveyor for coal washing. Since the coal blocks themselves contain moisture, some small pieces of coal blocks will adhere to the conveyor belt of the belt conveyor during transportation. Therefore, a cleaning machine is needed to clean the conveyor belt during the transportation of coal blocks.

[0003] The existing cleaning machine is generally a scraper cleaning machine or a roller brush cleaning machine installed at the end of the conveyor belt. The scraper is in contact with the conveyor belt to scrape off the coal blocks adhering to the conveyor belt during the movement of the conveyor belt, or the roller brush is rotated so that the roller brush rotates relative to the conveyor belt to clean the coal blocks adhering to the conveyor belt. However, during the cleaning process, the scraper and the roller brush cannot clean the coal blocks adhering to the conveyor belt because the coal blocks are wet and sticky, and both the scraper and the roller brush will scratch the conveyor belt, accelerating the wear of the conveyor belt. To this end, we propose a cleaning device for a coal washing belt conveyor. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 The utility model provides a technical solution: a cleaner for a coal washing belt conveyor, comprising a water collecting tank 9, the water collecting tank 9 is arranged below the belt conveyor, and sealing connecting plates 6 are fixedly installed on both sides of the top of the water collecting tank 9, and the top of the sealing connecting plate 6 is fixed on the belt conveyor;

[0020] The following is an introduction to the specific use of the belt conveyor. In actual use, a plurality of support rollers 17 are installed in the frame 1, and a driving roller shaft 14 is provided at both ends of the frame 1. The driving roller shaft is connected through the conveyor belt 10, and the conveyor belt is made of support rollers 17, so that the conveyor belt 10 has a large span and will not bend. Then the driving roller shaft 14 rotates under the drive of the driving motor 16, so that the conveyor belt 10 rotates. The bottom of the frame 1 can be fixed to the ground through the bracket 2, as shown in FIG. Figure 1 As shown, the water collecting trough 9 proposed by the utility model is arranged below the discharge end of the conveyor belt 10, and a plurality of connecting frames 18 are provided on the top edge of the sealing connecting plate 6, and the connecting frames 18 are connected to the frame body of the belt conveyor, that is, the connecting frames 18 are connected to the frame 1.

[0021] like Figure 3 As shown, during use, the coal blocks can be transported from the bottom end of the conveyor belt 10 to the top end thereof, and under the action of inertia, they move along a parabolic trajectory (such as Figure 3 The coal (as shown by the arrow A) falls into the coal washing pool for coal washing processing.

[0022] The specific structure of the water collection tank is introduced below. Figure 3 As shown, an arc plate 19 extending outward is installed on one side of the water collecting tank 9, and a scraper 20 is provided on the other side of the water collecting tank 9. The scraper 20 and the two ends of the arc plate 19 are respectively connected to the sealing connecting plate 6. The top of the sealing connecting plate 6 is fixed on the belt conveyor, and a gap is provided between the end of the arc plate 19 and the belt conveyor. Figure 3 The middle arrow B indicates that the conveyor belt 10 and the curved plate 19 will not touch each other, and the conveyor belt can carry the adhered coal to enter above the curved plate 19;

[0023] The scraper is located below the belt conveyor and the two are in clearance fit, that is, there is a small gap between the top of the scraper and the conveyor belt, so that the water on the surface of the conveyor belt can be scraped off and let the water fall into the water collecting tank 9. An elastic rubber sheet can also be connected to the top of the scraper to make the rubber sheet contact the surface of the conveyor belt, so that the rubber sheet can be in elastic contact with the surface of the conveyor belt, which can better scrape water;

[0024] like Figure 1 and Figure 2As shown, a cleaning pipe 13 is provided inside the water collecting tank 9, and both ends of the cleaning pipe 13 are fixed on the side of the sealing connecting plate 6, and a plurality of spray holes 12 are equidistantly opened on the side of the cleaning pipe 13, and the spray holes 12 face the belt conveyor. One end of the cleaning pipe 13 extends outside the water collecting tank 9, and the end of the cleaning pipe 13 extending outside the water collecting tank 9 is connected to a pumping mechanism through a flange joint 7, and the pumping mechanism includes an outlet pipe 5 connected to the end of the cleaning pipe 13 through the flange joint 7, and the other end of the outlet pipe 5 is fixed on the high-pressure water pump 4, and the high-pressure water pump 4 is connected to the frame 1 through the mounting plate 8, and the water inlet pipe 3 is connected to the water inlet of the high-pressure water pump 4. The high-pressure water pump 4 sprays the external water source through the spray hole 12 at a high speed to the ground of the conveyor belt 10, which can wash away the coal slag particles adhered to the conveyor belt 10 without causing wear to the conveyor belt 10, and the mounting plate 8 is arranged on the side of the sealing connecting plate 6.

[0025] like Figure 3 As shown, the bottom of the water collecting tank 9 is detachably connected with a drain pipe 11 through a pipe joint 15, and the detachable connection is a threaded connection or a bolted connection, so that the drain pipe 11 can be easily removed for replacement when it is damaged. The drain pipe 11 is connected to the inside of the water collecting tank 9, and the bottom of the water collecting tank 9 is funnel-shaped, and the funnel-shaped bottom matches the pipe joint 15. In this way, during the flushing process, the cleaning water and coal blocks that fall into the water collecting tank 9 will all flow into the drain pipe 11 along the funnel-shaped bottom of the water collecting tank 9 and be discharged, and will not remain in the water collecting tank 9. The drain pipe 11 is directly placed in the coal washing pool, that is, the coal slag washed off the conveyor belt 10 will be discharged along the drain pipe 11, and the discharged coal blocks will fall into the coal washing pool together with the coal blocks conveyed by the conveyor belt 10 under the action of gravity and inertia, avoiding waste.

[0026] Specifically, when the utility model is in use, the high-pressure water pump 4 is controlled to work, and the high-pressure water pump 4 transports the external water source to the cleaning pipe 13 through the water inlet pipe 3 and the water outlet pipe 5, and makes the water spray at high speed to the bottom surface of the conveyor belt 10 through the spray hole 12, so as to wash away the coal blocks adhering to the bottom surface of the conveyor belt 10, and the washed coal blocks are discharged into the coal washing pool along the drain pipe 11 together with the cleaning water.

[0027] Furthermore, both ends of the top of the water collecting trough 9 are located below the conveyor belt 10 and there is a gap between them and the bottom of the conveyor belt 10. The gap allows the coal blocks adhering to the conveyor belt 10 to pass through, so that during the coal transportation process, the water collecting trough 9 will not be scratched against the conveyor belt 10, and thus will not cause wear to the conveyor belt 10, and the coal blocks adhering to the conveyor belt 10 will not be scraped off by the top of the water collecting trough 9. The coal blocks adhering to the conveyor belt 10 will all be washed away by the cleaning water sprayed from the spray hole 12 and then discharged into the coal washing pool along the drain pipe 11, without causing waste.
