Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor bulk material conveying equipment, and in particular to an automatic cleaning device for leaking material from a belt conveyor. Background Technology

[0002] During the conveyor belt transport of bulk materials, the belt may become sticky and cause the bulk materials to fall below the conveyor belt during the return trip. It is necessary to clean it manually or use a chain scraper cleaning device. However, both of these cleaning methods have shortcomings: I. Manual cleaning: (1) Low work efficiency, high labor intensity for workers, limited space and high risk factor of operation; (2) Manual cleaning requires stopping the line for cleaning, which reduces the operating efficiency of the equipment and affects the output value of the conveyor belt transport of bulk materials; II. Chain scraper cleaning device: (1) The chain and sprocket are easily jammed due to the accumulation of bulk materials, which requires regular maintenance and cleaning; (2) The scraper height is limited and the cleaning efficiency is low; (3) The lubricating medium of the sprocket and chain will contaminate the bulk materials; (4) The driving mechanism is powered by an electric motor, which poses a risk of leakage. The scraper may generate sparks when scraping against the bottom plate, which is not suitable for use scenarios with requirements for leakage prevention and explosion prevention; (5) The bottom plate and scraper are both made of metal, which is easy to wear after contact with bulk materials and has a short service life. Utility Model Content

[0003] The purpose of this invention is to provide an automatic cleaning device for leaking material from belt conveyors, which can solve the problems of low efficiency and poor safety of existing cleaning methods.

The upper part of the scraper is hinged to the movable frame, and the movable frame has a back plate on the side of the scraper facing away from the material discharge port.

[0005] A more specific technical solution in the above technical solution is that each of the guide support rails includes two circular steel pipes arranged vertically, and the middle part of the guide wheel is concave inward in an arc shape, so that it can be stuck between the two circular steel pipes and roll.

[0019] like Figures 1 to 9The automatic material leakage cleaning device for the conveyor belt shown includes a box with a material discharge port 1 at one end. The box includes a bottom plate 2, side plates 3 on both sides of the bottom plate 2, and end plates 4 on both ends of the bottom plate 2. The width of the end plates 4 is greater than the width of the bottom of the bottom plate 2, and the height of the end plates 4 is greater than the height of the side plates 3. Guide support rails 5 are provided on opposite sides of the box. The two ends of the guide support rails 5 are fixedly connected to the end plates 4. A movable frame is provided between the two guide support rails 5. Multiple guide wheels 6 are provided on both sides of the movable frame and are tactilely connected to the guide support rails 5. The movable frame is driven by a power cylinder 7 to move along the guide support rails 5. Multiple sets of scrapers 8 are provided inside the box. The multiple sets of scrapers 8 are arranged sequentially along the length of the movable frame. The upper part of the scraper 8 is hinged to the movable frame. A back plate 9 is provided on the side of the movable frame opposite to the material discharge port 1.

[0020] Each guide support rail 5 includes two circular steel pipes arranged vertically. The guide wheel 6 has an inwardly concave arc shape in the middle, allowing it to roll between the two circular steel pipes.

[0021] The movable frame includes two long rods 10, with multiple crossbars 11 equidistantly arranged between the two long rods 10. Reinforcing plates 12 are provided between the two ends of each crossbar 11 and the long rod 10. The upper part of a scraper 8 is hinged to the crossbar 11 via a hinge 13. The number of sets of scrapers 8 corresponds to the number of crossbars 11, with each set of scrapers 8 hinged to one crossbar 11. A back plate 9 is installed below the crossbars 11. In this embodiment, three scrapers 8 form a set. Guide wheels 6 are mounted on the outside of the long rods 10 via connecting shafts. The number of guide wheels 6 on both sides of the movable frame is the same, and their positions correspond to each other, so that the movable frame remains stable during movement.

[0022] There are two power cylinders 7, which are respectively located above the connection between the two long rods 10 and the crossbar 11. The cylinder body of the power cylinder 7 is fixed on the end plate 4 at the end away from the material drop port 1. The extended end of the power cylinder 7 is connected to the ear plate 14 located on the top of the moving frame.

[0023] The housing is equipped with a dust cover (not shown in the figure) around the power cylinder 7, and a steel base support 15 is provided below the bottom plate 2. The steel base support 15 is bent towards the side plate 3 on both sides.

[0024] The base plate 2, side plate 3 and scraper 8 are all made of ultra-high molecular weight materials, with ultra-high molecular weight polyethylene sheet being the preferred material.

[0025] The power cylinder 7 is connected to the air tank 17 via the air source triplet 16. The control valves of the power cylinder 7, the air source triplet 16, and the air tank 17 are electrically connected to the PLC control cabinet 18 with a touch screen.

[0026] This utility model is installed below the belt conveyor. During the return trip, loose material on the belt will fall into the housing. The power cylinder 7 is activated, and the power cylinder 7 drives multiple sets of scrapers 8 to move back and forth in the housing through the moving frame, sweeping the loose material out of the discharge port 1. The multiple sets of scrapers 8 use a unidirectional progressive pushing method during cleaning. The specific working principle is as follows: with one end of the housing with the discharge port 1 as the front and the other end as the rear, when the moving frame moves towards the discharge port 1, each set of scrapers 8 pushes the loose material a certain distance towards the discharge port 1. Under the action of the back plate 9, the scrapers 8 have sufficient pushing force when they encounter the loose material. Then the moving frame moves backward and then forward again, and the previous set of scrapers 8 pushes the loose material pushed by the next set of scrapers 8 towards the discharge port 1 again. In this layer-by-layer pushing, the loose material is pushed out of the discharge port 1. When the moving frame moves backward, the scrapers 8 encounter the loose material and are subjected to force. Under the action of the hinge, they will flip upward, allowing the scrapers 8 to move past the loose material and backward.

[0027] The power cylinder 7 uses compressed air as its power source, ensuring safety, environmental friendliness, and pollution-free operation, while avoiding the risk of electric leakage. A dust cover protects the power cylinder 7 from material leakage, extending its service life. A steel base support 15 is installed below the base plate 2 to ensure the strength of the main structure and meet the strength requirements for material leakage accumulation.

[0028] Using ultra-high molecular weight polymer materials for scraper 8, bottom plate 2, and side plate 3 increases wear resistance and extends service life. It also avoids sparks flying due to metal scraping, thus mitigating the risk of fire and explosion from a design perspective. It is especially suitable for explosive and flammable working conditions such as coal mines, resulting in higher product safety. The height and width of scraper 8 can be set according to the specific conditions of the bulk material.

[0029] Using a PLC control cabinet with a touch screen, automatic control functions such as timed start / stop operation, fixed number of actions per unit time, and fixed interval can be realized, achieving full automation, eliminating the need for manual cleaning and operation, and providing an unmanned cleaning solution.

[0030] It should be noted that the control methods and software methods involved in the PLC control cabinet of the cleaning device provided by this utility model are all common methods in the prior art, and do not involve any improvements in control methods and software. As for the connection methods between the various functional devices, they can all be implemented by those skilled in the art using existing technology, and will not be described in detail here.
