Screen mounting system

Abstract

The mobile mineral processing plant (100) is connected to the screen module (110) using a connection base (120). The connection base has first and second adapters (124, 127) for removably attaching the screen module (110) and exit conveyors (130, 132) to the mineral processing plant. When the mineral processing plant is moved laterally to engage the first connection portion (125) of the first adapter (124), the first adapter pivotally connects to the mineral processing plant. The second adapter (127) enables an actuator to lift the screen module along with the connection base, causing the screen module to pivot about the pivotal connection portion to a tilting operating configuration relative to the ground. The connection base is angled to horizontally position the reject conveyor (130) in the tilting operating configuration.

Description

Technical Field

[0001] The disclosure of this specification generally relates to a screen mounting system. Without limitation, the disclosure of this specification particularly relates to a screen mounting system for a mobile mineral processing plant. Background

[0002] This section describes useful background information, but note that it is not admitted that the techniques described herein represent the state of the art.

[0003] Various models of screens are provided for use in various mobile mineral processing plants. Attaching a certain model of screen to a certain mineral processing plant may require special attachment work. Therefore, attaching a desired model of screen to the model of the currently used mineral processing plant may require a lot of time and labor.

[0004] US2003 / 0146315A1 discloses a screen assembly, and WO2006 / 051165A1 discloses a frame of a mobile mineral processing device and a multi-purpose fixing device. Summary

[0005] It is desired to facilitate the introduction of various screens into mineral processing plants.

[0006] The appended claims define the scope of protection. Matters not covered by the claims among the examples and technical descriptions of devices, products and / or methods in this specification and / or drawings are presented as background art or examples useful for understanding the present invention, rather than as embodiments of the present invention.

[0007] According to a first exemplary approach, a system for equipping a mobile mineral processing plant with a screen module is provided. This system includes a connection base having a longitudinal direction and a transverse direction, the connection base having a first end and a second end in the longitudinal direction, the connection base At the first end, a first adapter is provided which is detachably attached to the screen module and which is configured to detachably attach the connecting base together with the rotating mounting portion to the installed state of the mobile mineral processing plant, A second adapter, spaced apart from the first end, is detachably attached to the screen module and is configured to be detachably attached to the connecting base, and is configured to form an actuator attachment portion for the mobile mineral processing plant for raising the screen module to a working state around the rotating attachment portion. A second conveyor base extending longitudinally from the first conveyor base, the second conveyor base supporting the second exit conveyor, It has, The first conveyor base and the second conveyor base each define planes that differ only by vertical angles, The first adapter has a first connecting portion for connecting to the first main body side connecting portion of the mineral processing plant, The first connecting portion is configured such that the screen module can be connected to the mineral processing plant by moving the mineral processing plant laterally so that it engages with the first connecting portion by the first main body side connecting portion.

[0008] Attaching the screen module to the mineral processing plant can be simplified by enabling connection of the screen module to the mineral processing plant by moving the mineral processing plant laterally so as to engage with the screen module.

[0009] The system may include different or adaptable first adapters for two or more different screen modules of different sizes or shapes. The first adapters may be configured to be attached to a standard beam of the screen module frame by shape lock and / or friction lock.

[0010] The system may include different or adaptable second adapters for two or more different screen modules of different sizes or shapes. The second adapters may be configured to be attached to a standard beam of the screen module frame by shape lock and / or friction lock.

[0011] The different or adaptable first and / or second adapters enable the system to facilitate the installation of different models of screen modules into the mineral processing plant.

[0012] The shape of the first and / or second adapters and / or friction locks allow the screen module to be attached to the frames of screen modules from various manufacturers, for example by welding or drilling, without compromising the frame's strength.

[0013] The second adapter may have a second connecting portion. The frame of the mobile mineral processing plant may have a second frame-side connecting portion. The second connecting portion may be configured to lock the connection when the second frame-side connecting portion engages with the second connecting portion. The second connecting portion may be configured to automatically lock the connection when the second frame-side connecting portion engages with the second connecting portion.

[0014] Locking the connections protects the screen modules from being accidentally or maliciously disconnected from the mineral processing plant. Automatically locking the connections makes the locking more reliable and / or reduces manual operation.

[0015] The screen module may have a first end. The first adapter may be configured to support the first end. The second adapter may be configured to allow the second end of the screen module to be lifted. The second end of the screen module may be located on the opposite side from the first end of the screen module.

[0016] The first adapter may have a first coupling portion configured to connect to a first frame-side coupling portion of the frame of the mineral processing plant. The first coupling portion may be configured to enable a guided coupling. The first coupling portion itself may have a guiding coupling portion. The guiding coupling portion may have a slide-in connector. The slide-in connector may have an outward-opening guide configured to receive a connector receptacle. Alternatively, the slide-in connector may have a connector receptacle for entering into an outward-opening guide. The outward-opening guide may open vertically. Alternatively or additionally, the outward-opening guide may open horizontally.

[0017] The outward-opening guide facilitates alignment between the guide and the receptacle, making it easier to install the screen module in a mineral material processing plant.

[0018] The system may further include the screen module ground support. The screen module ground support may allow the screen module to be freely positioned on the ground without the need to prepare a platform for the screen module.

[0019] The screen module ground support may be configured to be attached to the frame of the screen module.

[0020] The screen module ground support may be configured to align the position of the first connecting portion with the first main body side connecting portion of the mineral processing plant. In this case, the screen module can be connected by moving the mineral processing plant. Thanks to the alignment, the first connecting portion can be connected to the first main body side connecting portion while the screen module is resting on the ground by the screen module ground support. The need for jacks or lifting devices, or the use of ramps or other temporary structures can be avoided. The connection can be performed by one person.

[0021] By simplifying the connection between screen modules and mobile mineral processing plants, it may be possible to switch screen modules on-site. For example, the sieving process can be adapted more efficiently to changes in the minerals being fed in or to fluctuations in the required screen product.

[0022] The frame of the screen module may have a first subframe configured to support a screen and a second subframe configured to support a second conveyor below the screen. The frame of the screen module may have one or more interlinks configured to detachably connect the first subframe and the second subframe. The one or more interlinks may have actuator holders configured to be attached to the first subframe and to the second subframe. The interlinks alone may be sufficient to prevent separation of the first subframe and the second subframe.

[0023] The screen module ground support may have a link member attached to the first subframe or the second subframe. The screen module ground support may have a detachable portion that is detachably attached to the link member. The link member may be formed as a cylindrical portion.

[0024] The separable part may have one or more first grounding members for placing the first section of the screen module so as not to move relative to the ground. The first grounding member may have a first body configured to support the frame relative to the ground. The first body may have a tubular member such as a pipe. The first section may be located closer to the first end of the screen module than to the second end of the screen module.

[0025] The separable part may have one or more second grounding members for placing the second section of the screen module so as not to move relative to the ground. The second grounding member may have a second body configured to support the frame relative to the ground. The second body may have a tubular member such as a pipe. The second section may be located closer to the second end of the screen module than to the first end of the screen module.

[0026] The first grounding member and the second grounding member may be detachably attached to the connection base. The ability to be detachably attached to the connection base may enable the first grounding member and the second member to be detachably attached at various intervals to screen modules of various sizes. The first and second grounding members may be configured to show a footprint surrounding the center of mass of the screen module so as to stabilize the ground support of the screen module when not connected to a mineral processing plant.

[0027] The separable part may have a grounding plate configured to contact the ground. The grounding plate may be integrally formed with the first grounding member and the second grounding member, or may be assembled as a permanent part of the first grounding member and the second grounding member. The grounding plate may include a slot-in member configured to connect to the first body or a slot-in member configured to connect to the second body.

[0028] The slot-in member can enable quick and easy attachment of the ground plate to the screen module ground support. The system may have a moving bracket including a slot-in member configured to be fitted into the first body and the second body. The moving bracket may be configured to function as a mounting rail for mounting the screen on a moving platform. The moving platform may be mounted on a lorry or a truck.

[0029] According to a second exemplary approach, a mobile mineral processing plant is provided that includes the system of the first exemplary approach for equipping a mobile mineral processing plant with a screen module.

[0030] According to a third exemplary approach, a coupling system is provided. This system comprises a coupling base having longitudinal and transverse directions, the coupling base having a first adapter and a second adapter respectively detachably attached together to a screen module, and having one or more outlet conveyors, detachably attaching the screen module and the one or more outlet conveyors to a mobile mineral processing plant, when moving the mineral processing plant laterally to engage a first connection portion of the first adapter, the first adapter is configured to be rotatably connected to the mineral processing plant, the second adapter enables an actuator to lift the screen module together with the coupling base so that the screen module rotates into an inclined movement configuration relative to the ground about the rotatable connection portion.

[0031] The coupling base may be angled to horizontally position a reject conveyor in an inclined movement configuration.

[0034] In the following description, similar symbols indicate similar elements or steps.

[0035] We have presented various embodiments. The words "to have," "to possess," and "to include" should be interpreted in an open-ended manner and do not exclude the existence of other elements.

[0036] The above description provides a complete and useful explanation of the best mode for carrying out the present invention as currently envisioned by the inventors, using specific implementations and non-limiting examples of embodiments. However, as will be apparent to those skilled in the art, the details of the embodiments described above are not limiting to the present invention and can be implemented in other embodiments using equivalent means or various combinations of embodiments without departing from the features of the present invention.

[0037] Furthermore, the features of the exemplary embodiments disclosed above may be used without the use of other corresponding features. However, the above description should be understood as merely an example to illustrate the principles of the present invention and not as a limiting reference. The scope of the present invention is limited only by the appended claims.

[0038] Figure 1 shows a system comprising a mobile mineral processing plant 100, a screen module 110, and a connecting base 120. The connecting base 120 supports the screen module and connects the screen module to the mobile mineral processing plant. The connecting base 120 also supports and connects outlet conveyors, such as a first outlet conveyor 130 and a second outlet conveyor 132.

[0039] The mobile mineral processing plant 100 comprises a frame 102, a self-propelled truck 104, a main body arm 106 formed by the frame, a first main body-side connecting portion 108, and a second main body-side connecting portion 109. The first main body-side connecting portion 108 is, for example, a shaft attached to the frame 102. The second main body-side connecting portion 109 is, for example, a recess or vertical groove formed on the upper surface of the main body arm 106. The main body arm 106 may be configured to suspend a screen module 110 by the second main body-side connecting portion 109. In this case, the screen module 110 is suspended at a lateral distance from the first main body-side connecting portion 108.

[0040] The screen module 110 has multiple screens 112.

[0041] The connecting base 120 includes a first conveyor base 121 extending over a first length from a first end, and a second conveyor base 122 whose longitudinal direction is continuous with the first conveyor base 121. The first conveyor base 121 supports a first exit conveyor 130, and the second conveyor base 122 supports a second exit conveyor 132. The connecting base 120 further includes a first adapter 124. The first adapter 124 is provided with a first connecting portion 125 for connecting to a first main body side connecting portion 108. The first adapter 124 is detachably attached to the first conveyor base 121. In an alternative embodiment, the first adapter partially or entirely forms the first conveyor base 121.

[0042] The connecting base 120 further includes a second adapter 127 having a second connecting portion 128 for connecting to a second main body side connecting portion 109. In some embodiments, the connecting base 120 further includes a plurality of legs 129 for supporting the screen module 110. Thus, the screen module 110 is self-supporting on the ground by the connecting base 120 in the first section S1 and second section S2 near the first end of the screen module 110.

[0043] In Figure 1, the dashed lines indicate two screen decks, each consisting of two screens. In other embodiments, there may be only one screen deck formed from one or more screens, or there may be more screen decks.

[0044] Figure 2 is an enlarged view of a portion of Figure 1. Figure 3 is a detailed view of a portion of Figure 1 when the mobile mineral processing plant 100 and the screen module 110 are connected using the connecting base 120. Figures 2 and 3 illustrate how the first connecting portion 125 and the first body-side connecting portion 108 engage with each other when the mobile mineral processing plant 100 is moved (e.g., driven or towed). Figures 2 and 3 also show that the first connecting portion 125 has a tapered opening that opens outward to facilitate connection. It should be understood that the implementation of the connection is freely modifiable. For example, one of the two connecting portions may have a ball or barrel surface. Similarly, the guide shape for facilitating connection may consist of only one of the connecting portions or both. Also, there may be two or more first connecting portions 125 and first body-side connecting portions 108. In some embodiments, there is only one first connecting portion and one first body-side connecting portion 108 so that the screen module can be suspended from three points.

[0045] Figure 4 is a side view of the mobile mineral processing plant and the screen module when connected. In this configuration, the first main body side connecting part 108 is pivotally connected, and the screen module 110 can be lifted upward by pivoting around the first connecting part 125.

[0046] The system in Figure 4 further comprises an actuator 410 having a first end 412 for coupling with a second adapter 127 and a second end 414 for coupling with the frame 102 (more precisely, the main arm 106) of the mobile mineral processing plant 100. The actuator 410 is, for example, a hydraulic actuator. The actuator 410 may receive its power from the screen module 110 or from the mobile mineral processing plant 100. In some embodiments, the actuator 140 is maintained in a pivotally connected state to which the actuator 410 receives its power, from the mineral material processing plant 100 or the screen module 110. The screen module 110 is flexibly supported on a connecting base 120, for example, via springs (not shown), thereby preventing excessive energy from being used to vibrate the screen of the screen module 110. It also allows the second conveyor 132 to be vibrated without fatigue. The connecting base 120, the first adapter 124, and the second adapter 127 together form a suspension structure that suspends the screen module 110 from the mobile mineral processing plant 100. Figure 4 further shows the first conveyor 130, which is composed of the screen module 110. In Figure 4, the first conveyor 130 is supported by the connecting base 120 between the screen module 110 and the mobile mineral processing plant 100.

[0047] In some embodiments, the mineral material processing plant 100 and the screen module 110 are configured to be installed in a fixed state. Advantageously, the legs 129, the first and second connecting parts 125, 128, and the main body connecting parts 108, 109 are arranged such that this fixed state occurs when the screen module 110 is stationary on level ground by the connecting base 120. In some embodiments, the first main body connecting part 108 is configured to connect the screen module 110 to the mineral material processing plant 100 by driving or towing the mobile mineral material processing plant 100 so as to engage with the first connecting part 125 of the screen module 110.

[0048] Figure 5 shows the mobile mineral processing plant 100 and the screen module 110 in use. At this time, the screen module 110 is connected to the mobile mineral processing plant 100 using a connecting base, rotated upward around the first connecting part 125 by the actuator 410, and locked in a predetermined position by the second connecting part 128.

[0049] The first conveyor base 121 and the second conveyor base 122 define planes that differ by a vertical angle α. The vertical angle α may be such that the first conveyor base 121 is horizontal when viewed in the longitudinal direction of the connecting base 120 when the mineral processing plant 100 is processing minerals in the screen module 110.

[0050] Figure 6 is a detailed view of a portion of Figure 5. The second end of the actuator 410 is configured to engage with a receiver 610 located on the frame 102 or main arm 106 of the mineral processing plant 100. A connecting pin or bushing 620 is inserted through the loop of the second end 414 of the actuator 410, forming an actuator mounting portion with the receiver 610. This mounting portion allows the actuator 410 to lift the screen module 110 around the rotating mounting portion by the connecting base into the operating state shown in Figure 5.

[0051] In Figure 6, the components for mounting the actuator 410 and the components for connecting the screen module 110 to the second connector 128 are arranged separately and at intervals. However, in other embodiments, these functions are integrated, either entirely or partially. For example, the receiver 610 in Figure 6 can not only receive the second end 414 of the actuator 410 but also serve as a second body-side connector 109 to receive the second connector 128. With an appropriate guide shape, the second connector 128 may be secured to the receiver 610.

[0052] In some embodiments, the second connecting portion 128 is configured to lock the connection. For this purpose, for example, a locking pin or a padlock can be used. If the receiving portion 610 is also used as the second main body side connecting portion, the lock may be implemented by forming a self-locking mechanism that prevents it from moving backward. In this case, the actuator may be reoperated to move the second connecting portion 128 upward away from the receiving portion 610 and release the lock. The lock may be bypassed by an automatic mechanism or manually. For example, the receiving portion may be blocked by a bypass component of appropriate shape that guides the connecting portion to pass through the receiving portion. Such a bypass component may be hinged or slidably connected to the screen module to avoid loss of the bypass component and to improve safety. The bypass component may be operated by the operation of the actuator 410 or manually. The lock is configured to secure the connection to prevent the screen module 110, or more precisely, the connecting base 120 supporting the screen module 110, from being accidentally or maliciously disconnected from the mineral processing plant 100. By automatically locking the connection, the lock can be made more reliable and / or manual operation can be reduced.

[0053] Figure 7 shows a portion of the connecting base 120 and the second conveyor 132 of Figure 1. The connecting base 120 has two pairs of link members 710 attached, for example, by welding or bolting. The link members 710 are made up of, for example, relatively short pipe pieces or loops. The link members 710 are configured to receive slot members 920 of the moving platform 900 shown in Figure 9 or the leg portion 129 shown in Figure 13. Each of these slot members 920 is formed corresponding to a link member 710. The link members also form the first conveyor base 121, either entirely or partially.

[0054] Figure 8 shows a portion of the screen module assembly and the connecting base 120 of an exemplary embodiment. The connecting base 120 comprises a first adapter 124 having a winding or pulling loop 810 and a first connecting portion 125. Figure 8 shows how the second adapter 127 mounts the screen module 410 and the connecting base 120 together and supports the actuator 410. Figure 8 further shows how the second adapter 127 functions as an actuator holder. In some embodiments, the actuator holder has a slot between two plates forming a body for the second adapter 127. This slot may be formed to have an opening aligned with the loop present at the end of the actuator 410.

[0055] Figure 9 shows a movable bracket 900 of an exemplary embodiment, as described in relation to Figure 7. The movable bracket has a movable beam 910 in addition to the aforementioned slot member 920. The movable beam 910 allows the supported screen module to slide back and forth on the movable platform. A winch is used to pull a hoisting or towing loop 810 to slide the screen module on the movable beam 910. The loop 810 can also be used to tow the screening module in the field, with the movable beam 910 acting as a sled. The movable bracket further comprises a transverse structure for supporting the beam in place, which is formed in this case by two crossbars 930. The movable bracket 900 can be attached to the link member 710 by simply lifting the screen module and then lowering the link member 710 so that it aligns and connects with the slot member 920. In some embodiments, this lifting is conveniently performed using actuators 410 (preferably at least one on each side). If space is limited, the space below can be increased by operating or towing the mineral processing equipment over a small pile of sand or a small mound of earth. The movable bracket 900 may be locked in place on the screening module, for example, using pins inserted into aligned holes in the link member 710 and the slot member 920.

[0056] Figure 10 shows a portion of the screen module assembly from Figure 8, combined with the movable bracket from Figure 9 so that it can be moved.

[0057] Figure 11 shows first adapters 124, 124' of two different exemplary embodiments for fitting together different screen modules and mobile mineral processing plants. By forming appropriate vertical and horizontal offsets for the first coupling portion 125 (shown in Figure 8), the desired alignment can be provided for the first end of the screen module.

[0058] Figure 12 shows second adapters 127, 127' of two different exemplary embodiments. Similar to the first adapters 124, 124' which adapt different screen modules and mobile mineral processing plants by suitably aligning the first end of the screen module, the second adapters 127, 127' allow for suitably aligning the second end by supporting the screen module 110 at a desired height relative to the second conveyor 132.

[0059] Figure 13 shows the legs 129 of the mobile mineral processing plant shown in Figure 1. Figure 13 further shows the slot member 920 and the ground plate 1310.
