Description

Technical Field

[0001] The present application relates to the technical field of material screening and processing, and in particular to a screen roller cleaning device and a material screening system. Background Art

[0002] The screening machine has strict requirements on the moisture content of the screened materials. If the moisture content is too high, it will cause material sticking to the screen roller of the screening machine, that is, the material is easily stuck in the gap of the screen roller. Therefore, in order to ensure the normal operation of the screening machine and not cause the equipment to be unusable due to sticking, the screening machine needs to be equipped with a screen roller cleaning device.

[0003] The cleaning device mainly breaks up the materials stuck in the gap of the screen roller to make the materials fall. The cleaning device and the materials will wear each other in the process of cleaning the screen roller. After a long period of operation, unnecessary gaps will be generated between the cleaning device and the screen roller due to wear, that is, in the radial direction of the screen roller, the cleaning depth of the cleaning device is reduced, thereby reducing the cleaning effect. At present, to address this problem, the screen roller cleaning device configured as a grate plate is usually arranged into a structure that can be adjusted up and down. When the cleaning device is worn and a gap is generated with the screen roller, the screen roller cleaning device can be adjusted up and down to eliminate the gap between the cleaning component and the screen roller in the radial direction of the screen roller. However, when adjusting and maintaining the grate plate, maintenance personnel are required to enter the screen roller for adjustment and maintenance. The maintenance process is relatively cumbersome and has certain safety risks. Utility Model Content

[0039] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0040] First, as Figure 1-Figure 4 As shown, the embodiment of the present application provides a screen roller cleaning device, which includes a carrier body 1, a carrier 2, a cleaning member 3 and an adjustment assembly 4; the carrier body 1 is used to be fixedly installed on the ground or other fixed facilities; the carrier 2 is rotatably connected to the carrier body 1, so that the carrier 2 can rotate freely on the carrier body 1. In actual implementation, the rotation center axis of the carrier 2 is parallel to the axis of the screen roller 5; the cleaning member 3 is connected to the carrier 2, and the cleaning member 3 is used to extend into the screen roller 5 from the outside to clean the screen roller 5, that is, the cleaning member 3 has a certain length, and the shape and size of the cleaning member 3 are The adjusting component 4 is configured to be able to extend into the gap of the screen roller 5 to contact the material stuck in the gap of the screen roller 5. During the rotation of the screen roller 5, the material stuck in the screen roller 5 can be broken up and fall by the cleaning member 3; the adjusting component 4 cooperates with the bearing member 2 to drive the bearing member 2 to rotate on the bearing frame 1, that is, the bearing member 2 is controlled by the adjusting component 4 to rotate. After the adjusting component 4 drives the bearing member 2 to rotate, the bearing member 2 synchronously drives the cleaning member 3 thereon to rotate. The relative position of the cleaning member 3 with the screen roller 5 will change during the rotation, thereby realizing the adjustment of the distance between the cleaning member 3 and the screen roller 5.

[0041] It should be noted that, in the initial installation state, the length direction of the cleaning member 3 does not coincide with the radial direction of the screen roller 5 .

[0042] The screen roller cleaning device provided in the embodiment of the present application, after fixing the supporting frame 1, drives the supporting member 2 to rotate on the supporting frame 1 by operating the adjusting component 4, and the supporting frame 1 can drive the cleaning member 3 to move, thereby changing the radial distance between the cleaning member 3 and the screen roller 5, thereby eliminating the gap between the screen roller 5 and the cleaning member 3 caused by wear, ensuring that the cleaning member 3 can contact the sticky material to break it up, thereby cleaning the screen roller 5.

[0043] The screen roller cleaning device provided in the embodiment of the present application does not need to enter the screen roller 5 for adjustment and maintenance. It only needs to adjust the cleaning device outside the screen roller 5. The maintenance process is relatively simple and convenient, and the safety risk is relatively low.

[0044] In some optional embodiments, the number of cleaning elements 3 is configured to be multiple and arranged linearly at intervals on the carrier 2, that is, the multiple cleaning elements 3 and the carrier 2 together constitute a comb-like structure, so that the multiple cleaning elements 3 can clean multiple gaps on the screen roller 5. In actual implementation, each cleaning element 3 corresponds to each gap on the screen roller 5, that is, the number of cleaning elements 3 can be adaptively set according to the gaps on the screen roller 5, wherein the arrangement direction of the cleaning elements 3 is parallel to the rotation center axis of the carrier 2.

[0045] In the embodiment of the present application, the screening roller 5 is driven by the rotating shaft to rotate the screening protrusions thereon to achieve material screening, and the gap mentioned above refers to the gap between adjacent screening protrusions.

[0046] In some optional embodiments, the support member 2 is configured as an axis body. In actual implementation, the support member 2 can be configured as an optical axis, so that the mass distribution of the support member 2 in the circumferential direction is uniform, the rotation adjustment is smoother, and the rotation angle is easier to control. The number of support frame bodies 1 is configured to be at least two, wherein the two support frame bodies 1 are respectively rotatably connected to the axial ends of the support member 2. In actual implementation, the support member 2 can be rotatably connected to the support frame body 1 through a bearing to ensure the smoothness of the rotation of the support member 2 and improve the convenience during the rotation adjustment process.

[0047] In some optional embodiments, the cleaning member 3 is detachably connected to the carrier 2. In this way, when the wear of the cleaning member 3 exceeds the maximum wear limit, the cleaning member 3 can be replaced separately without replacing the entire cleaning device, and the maintenance cost is relatively low.

[0048] In some optional embodiments, a first slot is configured on the carrier 2, and the cleaning member 3 is connected to the carrier 2 through the first slot. In actual implementation, the first slot can be configured as a dovetail slot, and the cleaning member 3 can slide in the first slot after being matched with the first slot to adjust the spacing between adjacent cleaning members 3, so as to adapt to screen rollers 5 of different specifications and sizes. Among them, a set screw can be configured on the cleaning member 3, and when the cleaning member 3 is adjusted into place, the cleaning member 3 can be relatively fixed to the carrier 2 through the set screw to prevent the cleaning member 3 from accidentally sliding and affecting the cleaning effect.

[0049] In some optional embodiments, the adjustment component 4 includes an adjustment mounting seat 41, an adjustment member 42 and an action member 43; the adjustment mounting seat 41 is relatively fixed to the support frame body 1. In actual implementation, the adjustment mounting seat 41 can be fixed to the ground or fixedly connected to the support frame body 1; the adjustment member 42 is movably connected to the adjustment mounting seat 41; the action member 43 is connected to the support member 2 and cooperates with the adjustment member 42 in transmission; wherein, when the action member 43 is driven by the adjustment member 42, the action member 43 can drive the support member 2 to rotate on the support frame body 1.

[0050] In the embodiment of the present application, the actuating member 43 can be driven by the adjusting member 42 to rotate on its own, the rotation center axis of the actuating member 43 is colinear with the rotation center axis of the supporting member 2, and the actuating member 43 can be located at one axial end of the supporting member 2 to drive the supporting member 2 to rotate; the actuating member 43 can also be driven by the adjusting member 42 to rotate circumferentially around the supporting member 2, and the actuating member 43 can be located on the axial section of the supporting member 2 to drive the supporting member 2 to rotate.

[0051] In some optional embodiments, the adjusting member 42 is configured as a bolt and the number of the adjusting members 42 is configured as two, the number of the action members 43 is configured as two and they are respectively connected to the two sides of the rotation center axis of the carrier 2, that is, the action member 43 is connected to the shaft section of the carrier 2 and the two action members 43 are arranged in a central symmetry about the rotation center axis of the carrier 2, the adjusting member 42 is threadedly matched with the adjusting mounting seat 41 and is slidably matched with the action member 43, wherein the head of the adjusting member 42 can form a contact and sliding match with the action member 43; for example, the action member 43 can be constructed as a square block with a certain length, the two adjusting bolts are respectively located below the two square blocks and are respectively in contact with the two square blocks to form a sliding match, and the action member 43 can drive the carrier 2 to rotate by adjusting one of the adjusting bolts to rise and adjusting the other adjusting bolt to fall. Compared with the setting method of the action member 43 rotating by itself, the method of rotating the action member 43 around the carrier 2 has lower assembly accuracy requirements and a more convenient implementation process.

[0052] In some optional embodiments, the action member 43 is detachably connected to the bearing member 2. The contact precision may decrease after the action member 43 and the adjusting bolt slide for a long time, so the action member 43 can be replaced to ensure the contact precision and facilitate maintenance.

[0053] In some optional embodiments, a second slot is configured on the carrier 2, and the action member 43 is engaged with the carrier 2 through the second slot. This arrangement can facilitate the replacement of the action member 43 and improve the convenience of the maintenance process; the second slot can also be configured as a dovetail slot, and the action member 43 can be relatively fixed to the carrier 2 through a set screw.

[0054] Second, as Figure 5As shown, an embodiment of the present application provides a material screening system, which includes a screen roller 5 and any one of the screen roller cleaning devices described in the first aspect; wherein, the cleaning member 3 in the screen roller cleaning device extends into the screen roller 5, and the length direction of the cleaning member 3 forms an angle with the radial direction of the screen roller 5, and the cleaning member 3 has a maximum cleaning depth in the initial installation state. When the end of the cleaning member 3 is worn, the distance between the end of the cleaning member 3 and the axis of the screen roller 5 becomes larger. At this time, the cleaning member 3 is rotated to reduce the radial angle between the cleaning member 3 and the screen roller 5, and the distance between the cleaning member 3 and the axis of the screen roller 5 becomes smaller accordingly so that the cleaning member 3 has a maximum cleaning depth.

[0055] The radial direction described in the embodiment of the present application can be understood as the direction of the perpendicular line between the axis of the screen roller 5 and the rotation center axis of the supporting member 2.
