Description

Technical Field

[0001] The present invention relates to the technical field of material transportation and processing, and in particular to a diversion-type self-adaptive bulk cargo high-efficiency water removal device. Background Art

[0002] In mines, bulk cargo conveying systems typically consist of multiple belt conveyors interconnected to form a complete bulk material conveying chain. These conveyors can be connected in a variety of ways, including front-to-back docking on the same centerline, vertical docking, and diagonal docking at specific angles. However, bulk cargo often contains a certain amount of moisture. While a small amount of moisture has little impact on loading, unloading, transportation, and storage, a high moisture content can make reloading difficult, impact equipment performance, and increase maintenance complexity. Furthermore, if the bulk material conveying chain is tilted at a certain angle, the material can slide down the conveyor.

[0003] The existing water removal methods mainly include vibration water removal and filter chute water removal.

[0004] However, there are problems: the vibration dewatering device, i.e., the vibrating screen or dewatering screen, needs to be installed at the bulk cargo transfer point, which takes up a large amount of space; at the same time, the vibration dewatering device has high energy consumption, which increases production costs; and during the strong vibration process, the bulk cargo particles may be damaged due to frequent collisions; finally, the vibration motor and related transmission components are prone to wear during long-term use and require regular maintenance and replacement, which increases the maintenance cost of the equipment. The existing filter chute dewatering equipment cannot divert bulk materials. Bulk materials with high moisture content and bulk materials with low moisture content are dewatered together through the filter chute, resulting in low filter chute dewatering efficiency; at the same time, the existing filter chute dewatering equipment cannot be dynamically adjusted and is difficult to adapt to different bulk cargo flows, which affects the dewatering effect.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figures 1-4 ; The present invention provides a diversion-type adaptive bulk cargo high-efficiency water removal device, comprising: a material distribution structure 1, a water removal structure 2 and a transfer structure 3, the material distribution structure 1 having a first discharge port 11b for discharging high-moisture content materials and a second discharge port 11c for discharging low-moisture content materials, respectively, and the material distribution structure 1 selects the first discharge port 11b or the second discharge port 11c according to the characteristics of the material; the water removal structure 2 is connected to the first discharge port 11b for dewatering high-moisture content materials, and the transfer structure 3 is connected to the second discharge port 11c and the water removal structure 2 for transferring low-moisture content materials and dewatered materials to the next workstation.

[0030] The diversion-type adaptive bulk cargo high-efficiency water removal device provided by the present invention includes a material distribution structure 1, a water removal structure 2 and a transfer structure 3. The material distribution structure 1 has a first discharge port 11b for discharging high-moisture content materials and a second discharge port 11c for low-moisture content materials, respectively. The material distribution structure 1 selects the first discharge port 11b or the second discharge port 11c according to the characteristics of the material; the water removal structure 2 is connected to the first discharge port 11b for dewatering high-moisture content materials, and the transfer structure 3 is connected to the second discharge port 11c and the water removal structure 2 for transferring low-moisture content materials and dewatered materials to the next workstation. When the moisture content of the material is high, the present invention discharges the material from the first discharge port 11b and is dewatered by the water removal structure 2. When the moisture content of the material is low, the material is discharged from the second discharge port 11c for direct transfer. The present invention can adapt to bulk cargo flows with different characteristics and improve processing efficiency.

[0031] In the case that there is no need to move the resin, multiple processes can be achieved to speed up the processing.

[0032] The material dividing structure 1 includes a material dividing shell 11, a material divider 12, a material divider adjustment member 13, and a material guide cylinder 14. The material dividing shell 11 is provided with a feed port 11a, a first material discharge port 11b, and a second material discharge port 11c. The material divider 12 is arranged in the material dividing shell 11, and the material guide cylinder 14 is fixed in the material dividing shell 11 and docked with the second material discharge port 11c. The material divider adjustment member 13 is fixed in the material dividing shell 11 and the movable end of the material divider adjustment member 13 is connected to the material divider 12 to drive the material divider 12 to move back and forth, so that the material divider 12 has at least a low moisture content material dividing state in which the material is guided to the material guide cylinder 14 and a high moisture content material dividing state in which the material is guided to the first material discharge port 11b.

[0033] Specifically, the distributor 12 includes an inclined plate 121 and an arc-shaped plate 122. The inclined plate 121 is inclined relative to the horizontal plane, and the arc-shaped plate 122 is arranged in the vertical direction. The higher end of the arc-shaped plate 122 is fixed to the higher end of the inclined plate 121, and the lower end of the inclined plate 121 is abutted against the end of the guide barrel 14. The lower end of the arc-shaped plate 122 extends to the first discharge port 11b. The divider adjustment member 13 is connected to the arc plate 122, pushing the arc plate 122 and the inclined plate 121 to move relative to the dividing shell 11. When the inclined plate 121 is completely below the feed port 11a, the divider 12 enters a low-moisture content dividing state. After the low-moisture content material enters from the feed port 11a, it falls on the inclined plate 121 and is guided into the material guide cylinder 14, and finally discharged from the second discharge port 11c; when the inclined plate 121 moves to one side and the arc plate 122 is located below the feed port 11a, the divider 12 enters a high-moisture content dividing state. After the high-moisture content material enters from the feed port 11a, it falls on the arc plate 122, is guided to the first discharge port 11b and is discharged.

[0034] Specifically, the divider adjustment member 13 includes a plurality of electric push rods 131, which are fixed in the divider housing 11 and have a retractable movable end. The movable end of the electric push rod 131 is connected to the divider 12. The movable end of the electric push rod 131 is retracted and retracted, thereby driving the divider 12 to move and switch between the low moisture content divider state and the high moisture content divider state.

[0035] Specifically, the material guiding cylinder 14 is cylindrical and is generally arranged in a vertical direction. The lower end of the material guiding cylinder 14 is connected to the second discharge port 11 c.

[0036] Specifically, the water removal structure 2 includes an arc-shaped screen 21, an angle adjustment member 22 and a water collecting funnel 23. The angle adjustment member 22 is fixed to the material distribution structure 1, and the movable end of the angle adjustment member 22 is connected to the arc-shaped screen 21. The arc-shaped screen 21 is arranged below the first discharge port 11b. The water collecting funnel 23 is fixed below the arc-shaped screen 21. The angle adjustment member 22 is used to drive the arc-shaped screen 21 to rotate relative to the first discharge port 11b to adjust the angle of the arc-shaped screen 21 relative to the first discharge port 11b.

[0037] Furthermore, the angle adjustment member 22 includes a pair of rotating motors, which are respectively arranged on both sides of the arc screen 21 and fixed to the arc screen 21 to drive the arc screen 21 to rotate relative to the first discharge port 11b to adjust the angle of the arc screen 21 relative to the first discharge port 11b.

[0038] Furthermore, the dewatering structure 2 includes a material baffle 24, which is positioned at the first discharge port 11b, fixed to the material distribution structure 1, and tilted toward the curved screen 21. The function of the material baffle 24 is to guide the high-moisture material that falls from the first discharge port 11b onto the curved screen 21. The rotary motor adjusts the angle of the curved screen 21 according to the characteristics of the bulk material, better adapting to the flow pattern of the bulk logistics, so that the bulk material fits the curved screen 21 as completely as possible for dewatering. The removed water is discharged through the water collection funnel 23.

[0039] Furthermore, the arc-shaped screen 21 is provided with a plurality of through holes 211, each of which is wedge-shaped. The aperture of the through hole 211 at the end facing away from the water collecting funnel 23 is smaller, while the aperture of the through hole 211 at the end close to the water collecting funnel 23 is larger. Due to the resistance of the material in the wedge-shaped through holes 211, a thin layer of water on the lower side is deflected and passes through between the through holes 211, entering the water collecting funnel 23 and flowing out. Since the size of the particles passing through the arc-shaped screen 21 is always smaller than the opening, the arc-shaped screen 21 has good non-clogging performance. Under typical feeding conditions, when oversized particles pass through the top of the arc-shaped screen 21, the leading edge of the through hole 211 removes water and fine particles until the cutting point size is reached. The arc-shaped screen 21 requires almost no maintenance during operation and only requires a very small head height for operation.

[0040] Specifically, the transfer structure 3 includes a secondary chute 31, a main chute 32, and a transport member 33. One end of the secondary chute 31 is disposed on the material discharge path of the curved screen 21 and is located below the curved screen 21. The other end of the secondary chute 31 extends above the transport member 33. One end of the main chute 32 is fixed to and docked with the second discharge port 11c, and the other end of the main chute 32 extends above the transport member 33. Material passing through the dewatering structure 2 falls onto the transport member 33 through the secondary chute 31 and is transported to the next processing station. Material with a low moisture content falls onto the transport member 33 through the main chute 32 and is transported to the next processing station.

[0041] In order to better understand the present invention, the technical solution of the present invention is described in detail below with reference to the accompanying drawings:

[0042] The first step is the adjustment device stage. According to the characteristics of the transported material, the electric push rod 131 is adjusted to drive the distributor 12 to move and switch it to the appropriate state (if the moisture content of the material is low, it is switched to the low moisture content distribution state, and if the moisture content of the material is high, it is switched to the high moisture content distribution state). The rotating motor rotates the arc screen 21 to the appropriate angle; followed by the second step of the distribution stage. The conveyor belt transports the bulk material into the dewatering chute. The material passes through the distributor 12 and the bulk material with high moisture content enters the dewatering structure 2, and the bulk material with low moisture content enters the guide cylinder 14; then the third step, the material During the material dehydration stage, bulk materials with high moisture content enter through the adjustable distributor, and are blocked by the baffle so that the materials enter the arc screen 21 vertically and are guided tangentially. Due to the resistance of the materials on the wedge-shaped through holes 211, a thin layer of water on the lower side is deflected and passes through between the wedge-shaped through holes 211, enters the water collecting funnel 23 and flows out, thereby achieving the effect of dehydrating the materials. Finally, in the fourth step, the transfer stage, the materials with low moisture content are directly transferred to the transport member 33 through the material guide barrel 14 and the main chute 32, and the dehydrated materials are transferred to the transport member 33 through the auxiliary chute 31.

[0043] Beneficial effects of the present invention: The diversion-type adaptive bulk cargo high-efficiency water removal device provided by the present invention includes a material separation structure, a water removal structure and a transfer structure. The material separation structure has a first discharge port for discharging high-moisture content materials and a second discharge port for low-moisture content materials, and the material separation structure selects the first discharge port or the second discharge port according to the characteristics of the material; the water removal structure is connected to the first discharge port for dewatering high-moisture content materials, and the transfer structure is connected to the second discharge port and the water removal structure for transferring low-moisture content materials and dewatered materials to the next workstation. When the moisture content of the material is high, the present invention discharges the material from the first discharge port and is dewatered by the water removal structure. When the moisture content of the material is low, the material is discharged from the second discharge port and directly transferred. The present invention can adapt to bulk cargo flows with different characteristics and improve processing efficiency.
