Description

Technical Field

[0001] The utility model belongs to the technical field of sintering equipment, and particularly relates to a belt redirecting roller scraping device. Background Art

[0002] The belt conveyor is an important material transportation system in the sintering system and also an important part of the production line. Any problem with a belt during production will cause the interruption of production operation. Therefore, the daily maintenance of the belt conveyor is particularly important. The belt conveyor also has many components, and only when all components can work properly can the safe operation be ensured. In sintering production, the materials transported by the belts in each system are different, and the impact on the belt facilities is also different. In the sintering mixing system, the transported materials are wet materials after being added with water and steam by the mixer. Equipment such as idlers and redirecting rollers in the belt facilities are also very prone to sticking materials. When there is too much sticking material, due to the uneven surface, it will affect the operation of the belt, easily cause the belt to deviate and slip, resulting in shutdown. At the same time, it will also affect the service life of the belt and the roller. It is only possible to regularly stop the machine to clean the rollers with more sticking materials, thus affecting the sintering output. Summary of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides a belt redirecting roller scraping device, which can quickly and efficiently clean the sticking materials on the roller without stopping the machine and can ensure the safety of the operators, and has good effects in terms of output, safety, equipment and other aspects.

[0004] The utility model is realized as follows.

[0005] A belt redirecting roller scraping device is arranged between the upper and lower rollers of the redirecting roller. It includes a strip-shaped scraping plate with an L-shaped cross-section composed of two vertical plate bodies. Connecting plates are welded on both the left and right sides of the scraping plate. Supports on both sides of the upper and lower rollers are welded with supports for connecting the scraping plate. Fixed plates parallel to the connecting plates are welded on one side of the two supports facing each other. The connecting plate and the fixed plate are detachably connected as a whole, so that the scraping plate is arranged on the support between the upper and lower rollers along the width direction of the roller. A handle perpendicular to one of the plate bodies is welded on the outer surface of one of the plate bodies of the scraping plate. A hole for the handle to pass through is opened on the belt conveyor guard net.

[0006] Before scraping, the scraping parts of the two plate bodies of the scraping plate are at a certain distance from the surfaces of the upper and lower rollers respectively.

[0007] When scraping, one of the plate bodies of the scraping plate contacts the surface of the sticking material roller corresponding to it.

[0008] Further, a first connection hole is provided on the connecting plate; a second connection hole corresponding to the first connection hole is provided on the fixing plate, and a connecting bolt is provided between the first connection hole and the second connection hole.

[0009] Further, both the first connection hole and the second connection hole are strip-shaped holes.

[0010] Further, any one of the plate bodies of the connecting plate and the scraping plate is fixed.

[0011] Further, the L-shaped cross-section of the entire scraping plate is fixed on the connecting plate.

[0012] Further, the handle is provided on one side of the plate body to which it is connected.

[0013] Further, a support rod extends towards the guard net on the support seat near the handle, and a stop rod for supporting the handle is vertically fixed at the end of the support rod.

[0014] Advantages and technical effects of the present utility model:

[0015] The belt redirecting roller scraping device of the present utility model has a simple structure, can be operated by one person, and can be used while ensuring safety without stopping the machine. It can not only quickly and efficiently clean the sticky material on the roller but also ensure the safety of the operators, and has good effects in terms of output, safety, equipment, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Such as Figures 1-3As shown in the figure, the utility model discloses a scraping device for a belt redirecting roller. The device is arranged between the upper and lower rollers of the redirecting roller and includes a strip-shaped scraping plate 1 with an L-shaped cross-section. Connecting plates 2 are welded on both the left and right sides of the scraping plate 1, and first connection holes are provided on the connecting plates 2. On the two side brackets 11 of the redirecting roller, supports 3 for connecting the scraping plate 1 are welded. On the opposite sides of the two supports 3, fixing plates 4 parallel to the connecting plates 2 are welded. Second connection holes corresponding to the first connection holes are provided on the fixing plates 4. A connecting bolt 5 is arranged between the first connection hole and the second connection hole, so that the scraping plate 1 is detachably connected to the roller bracket between the upper and lower rollers along the width direction of the roller.

[0022] After connection, the two mutually perpendicular end parts of the scraping plate 1 are at a certain distance from the surfaces of the upper and lower rollers respectively. Preferably, both the first connection hole and the second connection hole are strip-shaped holes, so that the distance between the scraping plate 1 and the surfaces of the upper and lower rollers can be adjusted.

[0023] The connecting plate 2 can be fixedly connected to any one of the plate bodies of the scraping plate 1, or for firm connection, the L-shaped cross-section of the whole scraping plate 1 can be welded to the connecting plate 2.

[0024] The scraping plate 1 includes two mutually perpendicular plate bodies. In order to enable the staff to clean the scraping plate 1 without stopping the machine when the surface of the roller is sticky, a handle 6 perpendicular to the plate body is welded on the outer surface of one of the plate bodies of the scraping plate 1. A hole for the handle 6 to pass through is provided on the belt conveyor guard net, so that the staff can stand outside the guard net and drive the whole scraping plate 1 to rotate towards the sticky roller side by lifting the handle 6. When the scraping plate 1 contacts the redirecting roller, the sticky material on the roller can be easily cleaned by using the principle of the self-rotation of the roller.

[0025] Preferably, when the scraping plate 1 is not in use, the handle 6 will rotate and fall due to the action of gravity and affect the normal operation of the lower roller. Therefore, a support rod 7 extends towards the guard net side on the support 3 close to the handle 6, and a stop rod 8 for supporting the handle 6 is vertically fixed at the end of the support rod 7. In order to minimize the length of the two support rods 7 as much as possible, the handle 6 is arranged on one side of the plate body connected to it rather than in the middle position.

[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
