Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, and particularly relates to a cleaning device for a belt conveyor used in fertilizer production. Background Art

[0002] A belt conveyor can form a material conveying process for materials on a certain conveying line from the initial feeding point to the final discharging point. It can convey both fragmented materials and finished items. In addition to pure material conveying, it can also cooperate with the requirements of the technological processes in the production processes of various enterprises to form a rhythmic flow production line.

[0003] In the process of fertilizer production, a belt conveyor is also used for material conveying. For example, a Chinese utility model patent with the publication number CN207580663U discloses an anti-adhesion device for a belt conveyor used in fertilizer production, including a fixed frame. An active roller and a driven roller are respectively fixedly installed at both ends of the fixed frame. A conveyor belt is arranged on the outer sides of the active roller and the driven roller. A feed hopper fixedly installed on the fixed frame through a bracket is arranged above the active roller. A supporting roller arranged on the inner side of the conveyor belt is fixedly installed on the fixed frame. Three supporting legs are fixedly installed at the bottom of the fixed frame. A pressing roller arranged on the inner side of the conveyor belt is fixedly installed in a chute on the supporting leg through a fastening knob. A baffle plate arranged on the conveyor belt is fixedly installed on the fixed frame. A runner connected to the active roller and a runner connected to the transmission shaft of a transmission motor are connected by a belt for belt transmission. A cleaning plate is fixedly installed on a connecting frame connected to the fixed frame. A runner connected to a rotating rod on a cleaning roller arranged below the fixed frame and a runner on the transmission shaft of a cleaning motor are connected by a belt for belt transmission. Uniformly distributed cleaning brushes are fixedly installed on the outer side of the cleaning roller. The beneficial effects of this utility model are as follows: This device can well clean the fertilizer adhered to the conveyor belt, thus well protecting the normal operation of the belt conveyor and effectively improving work efficiency. The design of the cleaning plate can well scrape the ingredients adhered to the conveyor belt and make the materials fall into the lower aggregate cylinder, thus reducing the load on the conveyor belt and enabling the fertilizer to be recycled and reused, effectively avoiding waste of resources. The cleaning roller further cleans the conveyor belt, thus improving the cleaning efficiency and preventing the conveyor belt from adhering to fertilizer, being able to well protect the normal operation of the device and extend its service life. However, there are also certain defects: The cleaning brushes and the cleaning plate in this utility model are in direct contact with the bottom surface of the conveyor belt. During the conveying process of the conveyor belt, the cleaning brushes and the cleaning plate continuously clean the conveyor belt, which is extremely likely to accelerate the wear speed of the conveyor belt surface and reduce the service life of the conveyor belt.

[0018] Embodiment

[0019] As Figures 1 to 3 shown, the present utility model discloses a cleaning device for a belt conveyor used in fertilizer production, including a mounting plate 1. A mounting frame 2 is provided on the top of the mounting plate 1. A conveyor belt 3 is provided inside the mounting frame 2. A cleaning mechanism is provided at the bottom of the conveyor belt 3, and the cleaning mechanism is fixedly arranged on the top surface of the mounting plate 1. The cleaning mechanism includes a cleaning brush 12 and a scraper 13. The scraper 13 is fixedly connected to the top surface of the mounting plate 1 through a scraper seat 14. The cleaning brush 12 is fixedly connected to the top surface of the mounting plate 1 through a cleaning support 15. The cleaning brush 12 is driven by a motor 8, and the cleaning brush 12 is located at the rear end of the scraper 13. By providing the cleaning mechanism, it is beneficial to clean the fertilizer adhered to the conveyor belt 3, thereby reducing the load on the conveyor belt 3 and at the same time being able to recycle the fertilizer. During cleaning, first scrape with the scraper 13 and then perform secondary cleaning with the cleaning brush 12 to ensure the cleaning effect.

[0020] Both sides of the bottom of the mounting frame 2 are provided with guide rods 4. Both of the guide rods 4 penetrate through the mounting plate 1 and extend downward. A guide sleeve 11 is provided at the bottom of the mounting plate 1, and the guide rods 4 are arranged inside the guide sleeve 11. A spring 10 is sleeved outside the guide rods 4. One end of the spring 10 abuts against the mounting frame 2, and the other end abuts against the mounting plate 1. Both lower ends of the guide rods 4 are hinged with a first connecting rod 5. The other ends of both first connecting rods 5 are hinged with a second connecting rod 6. The other ends of both second connecting rods 6 are respectively fixedly connected to two ratchets 7. The two ratchets 7 are respectively driven by motors 8, and the opposite sides of the two ratchets 7 are respectively rotatably connected to two end faces of a concentric disk 9. By arranging two motors 8 to respectively drive the two ratchets 7 to rotate, and then driving the guide rods 4 to move up and down to realize the lifting of the conveyor belt 3. When the conveyor belt 3 descends, the conveyor belt 3 contacts the cleaning mechanism to clean its belt surface. The intermittent cleaning method can extend the service life of the conveyor belt 3, slow down the wear speed of the cleaning mechanism on the conveyor belt 3, and reduce the enterprise cost.

[0021] Working principle: When it is necessary to clean the conveyor belt 3, the two motors 8 rotate clockwise by a certain angle, and then drive the second connecting rod 6, the first connecting rod 5 and the guide rod 4 to move downward, so that the conveyor belt 3 moves downward. At this time, the lower belt surface of the conveyor belt 3 contacts the cleaning brush 12 and the scraper 13 in the cleaning mechanism. During the transmission of the conveyor belt 3, the scraper 13 first cleans the conveyor belt 3, and then the cleaning brush 12 performs secondary cleaning, improving the cleaning effect of the conveyor belt 3. After the cleaning is completed, the two motors 8 rotate counterclockwise by a certain angle, driving the second connecting rod 6, the first connecting rod 5 and the guide rod 4 to move upward, so that the conveyor belt 3 moves upward, and the conveyor belt 3 is separated from the cleaning mechanism, and the material conveying work can be carried out again. The intermittent cleaning method can extend the service life of the conveyor belt 3, slow down the wear speed of the cleaning mechanism on the conveyor belt 3, and reduce the enterprise cost.
