[0002] In production workshops such as thermal power plants, steel plants, and chemical plants, conveyor belts are often used to transport bulk materials such as coal. During the transportation of bulk materials, the material flow often contains debris such as packaging bags. If not removed in time, the debris may entangle and block the equipment, or even stop the equipment. In serious cases, the equipment may be damaged, requiring frequent manual cleaning, which is time-consuming and labor-intensive. Therefore, a debris removal device is needed to remove the debris.

When a feature is referred to as being "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0021] See also Figure 1-5 The present application provides the following technical solutions: a self-cleaning debris removal device, comprising an outer shell 1, wherein both front and rear ends of the outer side surface of the outer shell 1 are provided with a slide groove 18; the inner side surface of the slide groove 18 is slidably connected with a slider 15, and the outer side surface of the outer shell 1 is provided with a positioning plate 17 near the upper and lower ends of the slide groove 18, and the two positioning plates 17 are respectively connected to the upper and lower surfaces of the slider 15 through springs 16, and the slider 15 is rotatably connected with a rotating shaft 13 through a bearing, and a roller 7 is provided between the two rotating shafts 13, and the roller 7 is arranged on the upper left end of the inner side surface of the outer shell 1, and the inner side surface of the outer shell 1 is provided with a roller 7. A guide groove 2 is provided on the upper side of the end, the outer shell 1 is connected to a motor mounting seat through a support frame 5 arranged on the outer side thereof, a variable frequency motor 3 is installed on the motor mounting seat, and the output shaft of the variable frequency motor 3 is connected to the end of the rotating shaft 13 through a flexible connecting belt 14, and the outer side surface of the drum 7 is spirally evenly distributed with filter holes 11 and hooks 12, and the lower surface of the outer shell 1 is installed with a waste discharge port 6 and a discharge port 4, and an inclined guide plate 8 is provided on the inner side of the outer shell 1 near the drum 7, and a filter screen plate 9 is provided at the uppermost end of the discharge port 4, and the filter screen plate 9 is arranged below the guide plate 8.

[0022] Specifically, after the bulk material falls into the upper surface of the guide groove 2, it falls into the upper surface of the drum 7 through the guidance of the guide groove 2, and the drum 7 is driven to rotate by the variable frequency motor 3. The scattered material is discharged into the discharge port 4 through the filter hole 11 arranged on the outer side of the drum 7, and the hook 12 arranged on the outer side of the drum 7 brings the debris to the waste discharge port 6 and throws it down.

[0023] More specifically, during the unloading process, the material impacts the drum 7, causing the drum 7 to vibrate up and down, which can prevent the filter hole 11 from being blocked and facilitate the debris hung on the hook 12 to quickly fall off and fall into the waste discharge port 6.

[0024] Furthermore, the filtering hole 11 and the hook 12 are arranged at intervals.

[0025] Specifically, the hook 12 can be a straight rod or a curved hook.

[0026] Furthermore, the hook 12 disposed on the right end of the outer side surface of the drum 7 is disposed close to the discharge port of the guide groove 2 .

[0027] Specifically, the hook 12 can fully screen the material, thereby removing the debris in the material.

[0028] Furthermore, the filter screen plate 9 is provided with filter holes.

[0029] Specifically, the filter screen plate 9 can filter out debris, thereby reducing the loss of material spillage.

[0030] Furthermore, one end of the filter screen plate 9 is hinged to the upper end of the inner side surface of the discharge port 4, and the other end of the discharge port 4 is connected to the inner side surface of the discharge port 4 through an elastic bracket.

[0031] Specifically, when the debris falls, it can impact the filter screen plate 9, causing the filter screen plate 9 to vibrate up and down, thereby accelerating the filtering efficiency of the material.

[0032] When in use: This application is applicable to materials such as coal, coke, ore, limestone, etc., and is widely used in bulk material conveying systems of large and medium-sized thermal power plants, steel mills, and chemical plants. After the bulk material falls into the upper surface of the guide groove 2, it falls into the upper surface of the drum 7 through the diversion of the guide groove 2, and the drum 7 is driven to rotate by the variable frequency motor 3. The scattered material is discharged into the discharge port 4 through the filter hole 11 arranged on the outer side of the drum 7, and the hook 12 arranged on the outer side of the drum 7 brings the debris to the waste discharge port 6 and throws it down.

[0033] During the unloading process, the material impacts the drum 7, causing the drum 7 to vibrate up and down, which can prevent the filter hole 11 from being blocked and facilitate the debris hung on the hook 12 to quickly fall off and fall into the waste discharge port 6.

[0034] After the debris containing a small amount of material falls onto the upper surface of the filter screen plate 9, a small amount of material enters the discharge port 4 through the mesh holes of the filter screen plate 9. The debris can impact the filter screen plate 9 when falling, causing the filter screen plate 9 to vibrate up and down, which not only accelerates the discharge of the material, but also prevents the mesh holes from being blocked.

[0035] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
