Description

Technical Field

[0001] This application belongs to the field of belt conveyor technology, specifically relating to a belt conveyor cleaning device. Background Technology

[0002] Belt conveyors are widely used for transporting bulk materials. After the materials have been transported, damp or sticky materials often adhere to the surface of the belt. If not cleaned in time, this can lead to problems such as belt misalignment, accelerated wear, and material spillage along the way, affecting the normal operation of the equipment and increasing maintenance costs.

[0003] Existing belt conveyor cleaning devices mainly rely on mechanical scrapers for removal. However, for highly viscous materials, simple mechanical scraping has the following shortcomings: incomplete cleaning: there are tiny gaps between the scraper and the belt, and some thin layers of sticky material cannot be effectively removed, resulting in "secondary adhesion." Therefore, there is an urgent need for a cleaning device that is more efficient, more belt-friendly, and can effectively handle sticky residues. Summary of the Invention

[0004] To solve the above problems, the technical solution adopted in this application is: A belt conveyor cleaning device includes a belt conveyor, and a cleaning mechanism assembly is provided on the lower side of the belt conveyor. The cleaning mechanism assembly is provided with a drying component, a flushing component and a scraper assembly. The flushing component and the scraper assembly respectively abut against the conveyor belt of the belt conveyor. The drying component is used to spray high-pressure airflow onto the surface of the conveyor belt of the belt conveyor.

[0005] Furthermore, the drying assembly includes several high-pressure airflow nozzles and a distribution pipe. The high-pressure airflow nozzles are disposed on the cylindrical surface of the distribution pipe and are connected to the distribution pipe. The air inlet end of the distribution pipe is connected to a high-pressure air source system. The multiple high-pressure airflow nozzles are arranged along the width direction of the conveyor belt, and their spray trajectories collectively cover the width of the belt conveyor.

[0006] Furthermore, the high-pressure airflow nozzle is directed toward the surface of the belt conveyor and forms an acute angle of 15° to 45° with the surface of the conveyor belt.

[0007] Furthermore, the cleaning mechanism assembly includes a water tank, and the drying assembly, flushing assembly and scraper assembly are respectively disposed in the water tank. The water tank is provided with an inspection door, which is hinged to the water tank. The inspection door is provided with a handle and bolts, which are used to fix the inspection door and the water tank together.

[0008] Furthermore, the high-pressure air source system includes an air compressor, an air tank, a pressure regulating valve, and a moisture filter, for providing a high-pressure airflow with adjustable pressure and dryness.

[0009] Furthermore, the flushing assembly includes a water pump, a brush, a brush groove, a brush rod, and a first spring. The end of the brush abuts against the surface of the conveyor belt of the belt conveyor. Both sides of the brush are respectively engaged with the brush groove. The brush slides up and down in the brush groove. The brush rod is fixed below the brush. The first spring is sleeved on the brush rod. The bottom end of the first spring is fixed to the water tank.

[0010] Furthermore, it also includes an electrical control system, which is electrically connected to the belt conveyor and automatically starts the drying assembly and / or flushing assembly when the belt conveyor starts, and shuts down the drying assembly and / or flushing assembly after a delay when the belt conveyor stops.

[0011] Furthermore, the scraper assembly includes a scraper, a connecting rod, a rail groove, and a second spring. The connecting rod is fixed below the scraper, and the scraper abuts against the conveyor belt of the belt conveyor. The second spring is sleeved on the connecting rod, and the bottom end of the second spring is fixed to the water tank. The scraper moves up and down along the rail groove, and the second spring is used to maintain the upward movement of the scraper.

[0016] The present application will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present application.

[0017] like Figures 1 to 6 As shown, this application provides an embodiment of a belt conveyor cleaning device, including a belt conveyor 1 and a cleaning mechanism assembly 2. The cleaning mechanism assembly 2 is located below the belt conveyor 1, specifically below the return section of the conveyor belt, to perform cleaning when the conveyor belt returns. The cleaning mechanism assembly 2 contains a drying component 3, a flushing component 4, and a scraper assembly 5 arranged sequentially along the conveyor belt's running direction, but their order can be adjusted according to actual needs. The drying component 3 sprays high-pressure airflow onto the surface of the conveyor belt, while the flushing component 4 and the scraper assembly 5 respectively abut against the surface of the conveyor belt to achieve physical cleaning.

[0018] The cleaning mechanism assembly 2 includes a rectangular water tank 21 made of stainless steel, which offers excellent corrosion resistance. The top of the water tank 21 is open for easy installation and maintenance of internal components. An access door 22 is provided on the water tank 21, and is connected to the side wall of the water tank 21 by hinges for easy opening and closing. A handle 23 is installed on the access door 22 for easy operation. Bolts 24 are also provided on the access door 22 to secure it to the water tank 21 when closed, ensuring a tight seal. A drain valve (not shown) is located at the bottom of the water tank 21 for periodic drainage of wastewater. The dimensions of the water tank 21 are customized according to the width of the belt conveyor 1 to ensure coverage of the entire width of the conveyor belt.

[0019] The drying assembly 3 includes several high-pressure airflow nozzles 31 and a distribution pipe 32. The distribution pipe 32 is a horizontally positioned steel pipe, with its inlet end connected to the high-pressure air source system via a hose. The high-pressure air source system includes an air compressor, an air tank, a pressure regulating valve, and a moisture filter. The air compressor provides compressed air, the air tank stabilizes the air pressure, the pressure regulating valve adjusts the output air pressure (typically 0.5-0.8 MPa), and the moisture filter removes moisture from the air to ensure dry airflow. The high-pressure airflow nozzles 31 are evenly distributed on the cylindrical surface of the distribution pipe 32 and are connected to the distribution pipe 32. Multiple high-pressure airflow nozzles 31 are arranged along the width of the conveyor belt, and their spray trajectories collectively cover the entire width of the conveyor belt of the belt conveyor 1, ensuring thorough drying without dead angles. The spray direction of the high-pressure airflow nozzles 31 is towards the surface of the conveyor belt, forming an acute angle of 15° to 45° (preferably 30°) with the surface of the conveyor belt. This angle design enhances the stripping effect of the airflow on residual moisture while preventing airflow rebound. The drying assembly 3 is located inside the water tank 21, between the flushing assembly 4 and the scraper assembly 5, but its position can be adjusted as needed.

[0020] The rinsing assembly 4 includes a water pump 41, a brush 42, a brush groove 43, a brush rod 44, and a first spring 45. The water pump 41 is installed outside the water tank 21 and connected to a water source inside the tank 21 via a pipe to provide a high-pressure water flow. The brush 42 is made of nylon material, and its end abuts against the surface of the conveyor belt to scrub away adhering substances. The brush 42 is engaged on both sides within the brush groove 43, which is fixed to the inner wall of the water tank 21. The brush 42 can slide up and down within the brush groove 43 to adapt to the unevenness of the conveyor belt surface. The brush rod 44 is fixed below the brush 42, and the first spring 45 is sleeved on the brush rod 44, with its bottom end fixed to the bottom of the water tank 21. The first spring 45 provides an upward elastic force, ensuring that the brush 42 always maintains close contact with the conveyor belt surface, ensuring effective scrubbing. The water jet from the water pump 41 is directed through a nozzle (not shown) to the contact area between the brush 42 and the conveyor belt, enhancing the scouring force. Specifically, the water pump 41 delivers the cleaning fluid to the end of the brush 42 through a water pipe. In a more preferred embodiment, a suitable cleaning agent can be added to the cleaning fluid to enhance the cleaning effect of the brush.

[0021] The scraper assembly 5 includes a scraper 51, a connecting rod 52, a guide groove 53, and a second spring 54. The scraper 51 is made of polyurethane material, which is wear-resistant and elastic. Its edge abuts against the surface of the conveyor belt to scrape away stubborn adhering substances. The connecting rod 52 is fixed below the scraper 51, and the second spring 54 is sleeved on the connecting rod 52, with its bottom end fixed to the bottom of the water tank 21. The scraper 51 moves up and down along the guide groove 53 via the connecting rod 52. The guide groove 53 is fixed to the inner wall of the water tank 21, guiding the movement of the scraper 51. The second spring 54 provides an upward elastic force, maintaining the upward movement tendency of the scraper 51, ensuring that the scraper 51 always adheres to the surface of the conveyor belt, maintaining effective scraping even if the conveyor belt vibrates or wears.

[0022] This device also includes an electrical control system (not shown), which is electrically connected to the belt conveyor 1 and uses a PLC controller for automated control. When the belt conveyor 1 starts, the electrical control system automatically starts the drying assembly 3 and / or the flushing assembly 4 (which can be started simultaneously or individually according to settings). When the belt conveyor 1 stops, the electrical control system shuts down the drying assembly 3 and / or the flushing assembly 4 after a delay (the delay time is adjustable, usually 5-10 seconds) to ensure that residual material is thoroughly cleaned. The electrical control system can also be set to a manual mode for easy maintenance and debugging.

[0023] The operation process of the device in this application During the operation of belt conveyor 1, the conveyor belt passes through cleaning mechanism assembly 2: First, the water pump 41 of flushing component 4 starts, spraying high-pressure water and driving brush 42 to scrub the surface of the conveyor belt; then, the high-pressure airflow nozzles 31 of drying component 3 spray drying airflow to blow away moisture and loose materials; finally, the scraper 51 of scraper assembly 5 scrapes away any remaining stubborn adhering substances. Throughout the process, the electrical control system coordinates the operation of each component to ensure continuous and efficient cleaning. After shutdown, drying component 3 and flushing component 4 shut down after a delay to perform final drying and cleaning of the conveyor belt.

[0024] The belt conveyor cleaning device of this application achieves multiple efficient cleaning of the conveyor belt through the synergistic action of the drying component, flushing component, and scraper component. Its beneficial effects are significant: the device uses a combination of flushing, scraping, and high-pressure drying to thoroughly remove adhering materials and moisture from the surface of the conveyor belt, effectively preventing belt misalignment and wear caused by material accumulation; its elastically designed cleaning components can adapt to the surface condition of the belt to ensure continuous and effective contact; at the same time, the automated electrical control system realizes start-stop control linked with the main unit, greatly reducing manual intervention. This not only significantly improves cleaning efficiency and operational reliability but also effectively extends the service life of the belt conveyor, reduces maintenance costs, and has practical advantages of energy saving and environmental protection.

[0025] Of course, the above embodiments are not intended to limit this application, and this application is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this application should also fall within the protection scope of this application.
