Description

Technical Field

[0001] The invention belongs to the field of conveying machinery, and in particular relates to a rotary vertical hoist for vertically conveying loose materials. Background Art

[0002] According to their structural characteristics, conveying machinery can be divided into conveyors with flexible components (the traction component is a closed system with a reciprocating cycle, such as belt conveyors, chain conveyors, bucket elevators, etc.) and conveyors without flexible components (the rotational motion or vibration of the working components is used to transport materials in a certain direction, and the components do not have a reciprocating form, such as screw conveyors, vibrating conveyors, etc.).

[0003] In traditional sand and gravel aggregate production lines, materials need to be transferred and transported between different crushing equipment, and belt conveyors are currently usually used to complete the above work. Belt conveyors have the characteristics of strong conveying capacity and long conveying distance, but because belt conveyors can only be tilted within an angle of 15°-20°, and crushing equipment is generally arranged on the same plane with a height difference of 4-8 meters, in order to convey materials to the feed port of the crushing equipment at the corresponding height, the distance between the equipment can only be increased. The length and usage of the corresponding belt conveyor will increase significantly, and more land resources will also be occupied, resulting in increased costs and energy consumption. Sometimes the cost of belt conveyors will even account for more than 50% of the cost of the entire production line. Under increasingly stringent environmental protection pressure, the investment and operating energy consumption of the dust removal system have also led to a significant increase in the cost of aggregate preparation, reducing the competitiveness of the product.

[0004] Although there is a bucket elevator that can achieve vertical lifting of materials, this equipment uses an independent bucket and chain drive, with a relatively complex structure, low conveying efficiency, small feed particle size, and limited minimum conveying height, which cannot meet the use requirements of the sand and gravel aggregate production line.

[0005] Some belt conveyors have partitions on the rubber belts, which appropriately increase the conveying angle, but also reduce the conveying capacity and greatly reduce the service life, which still cannot meet the use requirements of the sand and gravel aggregate production line. Summary of the invention

[0006] The purpose of the present invention is to provide a rotary vertical hoist that can continuously transport materials vertically, shorten the material transmission distance between equipment, reduce the floor space of the production line, and reduce investment and use costs.

A cavity for carrying materials is provided in the drum, and the opening direction points to the rotary axis of the drum. A material blocking device is provided in the drum above one side of the rotating material lifting device. A follow-up mechanism is provided on the material blocking device. The material rises with the drum. When it runs to the material blocking device, the follow-up mechanism rotates synchronously with the drum to form a relatively synchronous transmission state between the material in the cavity and the material blocking device.

[0012] The belt forms an angle of 10-30° with the outer side of the arc-shaped side plate between the tensioning roller and the nearest belt-supporting roller.

[0013] The tensioning roller is mounted on the side plate through an adjusting device, and the tensioning roller can slide along the adjusting device.

[0014] The angle α between the partition and the radial radiation line of the drum rotation center along the drum rotation direction is 0-50°.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, the rotary vertical elevator 20 includes a base 1, a frame 2, and a drum 3. The frame 2 is installed on the base 1, and the drum 3 is located in the frame 2. The frame is a frame structure, and the inner width is greater than the outer width of the drum. A cavity for carrying materials is provided in the drum, and the opening direction points to the rotary axis of the drum. A material blocking device 6 is provided in the drum 3 above the side of the rotating material lifting device. The upper end of the material blocking device is connected to the frame through an upper bracket, and the lower end is connected to the frame through a lower bracket. A follow-up mechanism is provided on the material blocking device 6. The material rises with the drum. When it runs to the material blocking device 6, the follow-up mechanism and the drum 3 rotate synchronously so that the material in the cavity and the material blocking device 3 form a relatively synchronous transmission state.

[0045] like Figure 7 As shown, the material blocking device 6 includes two symmetrically arranged arc-shaped side plates 61, the center of the arc coincides with the center of the drum, a plurality of support rods 62 and a plurality of belt-supporting rollers 63 are arranged between the two side plates 61, a guide roller 64 is arranged at the upper end between the two side plates 61, and a tensioning roller 65 is arranged at the lower end, the distance between the tensioning roller 65 and the outer side of the side plate 61 is greater than the distance between the guide roller 64 and the outer side of the side plate 61, an annular belt 66 is sleeved on the outer side of the guide roller 64, the belt-supporting roller 63 and the tensioning roller 65, and the width of the belt 66 is greater than the width of the drum 3, the follow-up mechanism includes a partition 31 arranged in the drum cavity, and a transverse protrusion 67 arranged on the outer surface of the belt of the material blocking device, the interval between adjacent transverse protrusions 67 is equal to the arc length of the adjacent partitions 31 in the drum, and the transverse protrusion 67 is in contact with the partition 31 in the drum, see Fig.17The partitions of the drum may be arranged evenly or unevenly, preferably evenly, so that the balance of the drum is better than that of the partitions arranged unevenly.

[0046] like Figure 8 As shown, chain plates 69 connected end to end are mounted on the outer sides of the guide roller, belt support roller and tensioning roller of the material blocking device, and adjacent chain plates are hinged together by connecting clips 691, and the width of the chain plates 69 is greater than the width of the roller; the follower mechanism includes a partition plate arranged in the cavity, and a transverse protrusion arranged on the outer surface of the chain plate of the material blocking device, the interval between adjacent transverse protrusions is equal to the arc length of adjacent partition plates in the roller, and the transverse protrusions are in contact with the partition plates in the roller.

[0047] The drum is provided with a cavity for carrying materials. The drum may be provided with a partition plate, and the drum and the partition plate form a segmented storage space. It may also be a bucket wheel storage method. A protrusion or hook is provided on the outer surface of the bucket wheel, and a groove or hanging ring matching with the protrusion is provided on the belt or chain plate of the material blocking device. Alternatively, a groove or hanging ring is provided on the bucket wheel, and a protrusion or hook is provided on the belt or chain plate of the material blocking device. The protrusion matches the groove, and the hook matches the hanging ring. Alternatively, other mechanisms enable the bucket wheel and the belt or chain plate to follow, so that the material in the bucket wheel and the material blocking device form a relatively synchronous transmission state without sliding friction. The bucket wheel storage method is a prior art. The bucket wheel is provided with a protrusion, a hanging ring or a hook, and the belt or chain plate is provided with a groove, a hanging ring or a hook matching with it. This is also a prior art, and this application will not describe it in detail.

[0048] like Figure 3 As shown, the angle α between the partition 31 and the radial radiation line of the rotation center of the drum 3 along the rotation direction of the drum is 0-50°, and the optimal angle value is 30°.

[0049] The tensioning roller 65 is mounted on the side plate 61 via an adjusting device 68, along which the tensioning roller can slide. Fig. 9 As shown, the adjustment device is a limit block 681 with a slot or hole fixed on the arc-shaped side plate near the tensioning roller, and a shaft 682 is fixed on the end of the tensioning roller. The shaft slides in the slot of the block, and the part of the shaft extending out of the block has a limit nut 683, so that the tensioning roller can achieve the tensioning function. Of course, other structures can also be used as long as they can achieve the tensioning function of the tensioning roller. This is not to limit the adjustment device, but only a form that can achieve adjustment.

[0050] The distance between the outermost side of the stopper 6 and the innermost side of the drum 3, that is, the distance between the belt and the partition (the partition and the drum side wall are of the same height) is 10-30 mm, preferably 20 mm. The height of the transverse protrusion 67 on the belt 66 is 30-50 mm, and the optimal height of the transverse protrusion is 40 mm. There is a gap between the stopper and the drum to prevent friction. Only the transverse protrusion on the belt contacts the partition in the drum. The drum rotates, driving the belt to realize the follow-up movement of the stopper and the drum.

[0051] like Fig.10 As shown, the belt 66 forms an angle with the outer side of the arc-shaped side plate 61 between the tensioning roller 65 and the nearest belt-supporting roller 63, and the angle β is 10-30°, and the optimal angle value is 20°.

[0052] like Figure 6 As shown, Y-shaped rubber sealing strips 53 are provided on both side walls of the drum 3 to reduce leakage of materials.

[0053] like Figure 1 , Figure 2 , Figure 6 As shown, the rotary vertical hoist 20 also includes a supporting wheel 4. Two supporting wheels 4 are arranged on the horizontally arranged base 1. The supporting wheels 4 are symmetrically arranged on both sides of the base 1, and the rotation axis of the supporting wheel 4 is arranged parallel to the horizontal plane. A raceway 32 is fixedly arranged on the outer surface of the drum. The raceway 32 is concentric with the drum 3, and the raceway 32 is arranged in contact with the supporting wheel 4. The rotation axis of the raceway 32 is arranged parallel to the rotation axis of the supporting wheel 4.

[0054] The outer side of the raceway 32 is fixedly provided with a chain guide groove 33, and the chain guide groove 33 is evenly fixedly provided with a block 34 for blocking the chain 51. Figure 2 The angle between the distance between two adjacent blocks and the center of the roller is 45°-180°, and the optimal angle is 90°, that is, four blocks are evenly arranged on the entire circumference of the chain guide groove.

[0055] like Figure 5 As shown, the supporting wheel 4 includes a bearing seat 41, there are two bearing seats, a support shaft 42 is installed in the middle, two support hubs 43 are arranged on the support shaft 42, and a rim 44 is movably installed on each support hub, and the rim 44 is made of polymer material.

[0056] like Figure 6 As shown, a limiting device 5 is provided at the center of the two supporting wheels of the base, and two limiting wheels 52 are installed on the limiting device 5. The limiting wheels 52 are respectively located on both sides of the raceway 32 on the roller, and are respectively provided in contact with the two end surfaces of the raceway. A limiting device is provided in the middle of the base to restrict the roller from moving along the axial direction of the roller.

[0057] At least two anti-overturning devices 7 are also arranged above the frame 2, and the anti-overturning devices 7 are arranged in contact with the roller raceway 32. Figure 1 As shown, two anti-overturning devices are symmetrically arranged above the frame. In order to improve the anti-overturning effect, two anti-overturning devices can also be symmetrically arranged below the frame.

[0058] like Fig.11 , Fig.12 As shown, the anti-overturning device 7 includes a fixed bracket 71, an adjusting bracket 72, a roller clamping mechanism and a roller clamping mechanism adjusting mechanism. The fixed bracket 71 is fixed on the frame 2, and the lower end of the fixed bracket 71 is movably connected to the adjusting bracket 72, and the other end of the adjusting bracket 72 is connected to the roller clamping mechanism and the roller clamping mechanism adjusting mechanism.

[0059] The roller clamping mechanism adjustment mechanism includes an adjustment rod Ⅰ73 movably connected to the adjustment bracket 72 and the fixed bracket 71, and a compression spring 74 is sleeved on the adjustment rod Ⅰ73, and the compression spring 74 is located between the adjustment bracket 72 and the fixed bracket 71; the roller clamping mechanism includes a pressure wheel 75 installed at the end of the adjustment bracket 72, and there are two pressure wheels, which are symmetrically arranged on both sides of the roller 32, and the axis of the pressure wheel is arranged parallel to the axis of the roller, and the outer edge of the pressure wheel is provided with a rib away from the roller; the two are used in conjunction with each other.

[0060] There is another form of roller clamping mechanism adjustment mechanism, the upper end of the adjustment rod Ⅰ 73 extends out of the fixed bracket 71 and is installed with an adjustment nut 77; the roller clamping mechanism includes a stopper wheel 76 installed at the end of the adjustment bracket 72, the axis of the stopper wheel is perpendicular to the axis of the drum, and the outer diameter of the stopper wheel is in contact with the two end surfaces of the roller. The gap between the stopper wheel and the roller is adjusted by the nut to avoid friction. The adjustment screw is floating during operation. If the drum is displaced, the stopper wheel will be raised with it, and the power is cut off by the limit switch.

[0061] One structure of the anti-overturning device is equipped with a compression spring to ensure that the pressure wheel is always in contact with the roller raceway, applying a preload to offset the overturning moment generated during the operation of the roller and ensure the stable operation of the roller. At the same time, there are ribs on both sides of the pressure wheel to prevent the roller from overturning in extreme situations. Another structure uses a stopper wheel similar to the limit device.

[0062] The anti-overturning device 7 is also provided with a limit switch 78. Fig.11 The limit switch 78 is arranged on the fixed bracket, and the limit switch is electrically connected in series with the reduction motor. The limit switch is arranged, and when the roller deflects or jumps beyond the set value, the limit switch is activated, the power supply of the driving device is cut off, and the roller stops running. The driving device is connected to the backstop, and the backstop can lock the roller in case of reverse rotation.

[0063] like Fig.13 , Fig.14 , Fig.15 As shown, a driving device 9 is provided on one side of the base 1, and the driving device 9 includes a reduction motor 91 and a plurality of pin shafts 95 provided on the drum. The driving device has two forms, one is a pin tooth structure, and the other is a ring chain structure. The pin tooth structure is that a pin tooth sprocket 96 is provided on the reduction motor, and the pin tooth sprocket 96 is provided in contact with the pin shaft 95. The ring chain structure is that a ring chain sprocket 92 is provided on the reduction motor 91, and the ring chain sprocket 92 is provided in contact with the pin shaft 95.

[0064] A tensioning device 8 is arranged above the driving device, and the endless chain 51 surrounds the roller 3, the driving device 9 and the outer side of the tensioning device 8 to form a closed loop structure.

[0065] The tensioning device 8 includes a tensioning wheel 81, a swing frame 82, a swing frame bracket 83, an adjusting rod II 94, and a spring I 93. The tensioning wheel 81 is installed on the swing frame 82, the swing frame 82 is installed on the swing frame bracket 83, the adjusting rod II 94 is installed on the swing frame bracket 83, and the other end is connected to the swing frame 82, and the spring I 93 is installed on the adjusting rod II 94.

[0066] like Fig.13 , Fig.14 As shown, the reduction motor 91 is connected to the backstop 84, the backstop is connected to the chain sprocket 92 through the coupling 97 for transmission, the backstop 84 is connected to the base 1 through the swing frame bracket 83, and the backstop is installed on the swing frame bracket 83 on the tensioning device through the rubber pad 98 and bolts, so that the backstop has a certain degree of freedom of movement on the swing frame bracket. The purpose of this setting is to ensure that even if the coupling moves out of center with the chain sprocket during installation or operation, it can be adjusted through the relative movement of the backstop on the rubber pad, so that the backstop, coupling and chain sprocket always rotate coaxially, thereby improving the use efficiency of the driving device, coupling and backstop. At the same time, it simplifies the structural design and processing accuracy requirements and reduces the manufacturing cost.

[0067] like Figure 4 As shown, when the feed size is large, it will impact the drum and may cause damage. A buffer device can be set on the outside of the partition to reduce the impact of the material on the drum. The buffer device 12 includes a buffer plate 121, a buffer rubber 125, a fixing seat 123, and a rubber pressing plate 122. Square steels 124 are fixedly installed at both ends of the buffer plate. The square steels are symmetrically arranged and extend out of the buffer plate 121. The plane of the square steel close to the buffer plate is set at 45 degrees to the plane of the buffer plate.

[0068] like Figure 1 , Fig.16 , Fig.17As shown, the rotary vertical elevator 20 also includes a feeding belt conveyor 10 and a discharging belt conveyor 11. The discharging port of the feeding belt conveyor 10 is arranged at the lower inner part of the drum 3, and the feeding port of the discharging belt conveyor 11 is arranged at the upper inner part of the drum 3.

[0069] like Fig.16 As shown, a divider 16 is provided below the end of the material blocking device in the drum, and the divider 16 is installed on the frame. A discharge belt conveyor I111 and a discharge belt conveyor II112 are provided at the outlet of the divider. The discharge belt conveyor I111 and the discharge belt conveyor II112 are arranged on both sides of the drum.

[0070] The lifting method of the rotary vertical elevator: the material to be lifted enters the drum from the feeding port of the feeding belt conveyor, and the rotation of the drum drives the material to move upward; the drum continues to rotate, the angle between the partition and the horizontal plane gradually changes, and the material gradually flows toward the drum opening. Before the material flows out, the top of the corresponding partition contacts the horizontal protrusion on the belt or chain plate, driving the belt or chain plate to move synchronously. At this time, the material is confined in the drum under the cover of the belt; the drum continues to rotate, and when the partition passes over the top of the belt or chain plate, the material loses the cover of the belt and falls by its own weight, enters the feeding port of the discharging belt conveyor, and is transported out.

[0071] The present invention provides a rotatable drum, and a cavity for carrying materials is provided in the drum, a material blocking device is provided in the drum above one side of the rotating and lifting material, and a follower mechanism is provided on the material blocking device. When the material rises with the drum and runs to the material blocking device, the follower mechanism rotates synchronously with the drum to make the material in the cavity and the material blocking device form a relatively synchronous transmission state, thereby realizing vertical lifting of the material. During the working process, the various components of the material blocking device have basically no sliding friction with the material, and have a long service life, low energy consumption, short downtime and low maintenance cost.

[0072] The backstop is installed on the swing frame bracket on the tensioning device through rubber pads and bolts, so that the backstop has a certain degree of freedom of movement on the swing frame bracket. The purpose of this setting is that even if the coupling moves out of center with the chain sprocket during installation or operation, it can be adjusted through the relative movement of the backstop on the rubber pad, so that the backstop, coupling and chain sprocket always rotate coaxially, improving the use efficiency of the drive device, coupling and backstop. At the same time, it simplifies the structural design and processing accuracy requirements and reduces the manufacturing cost.

[0073] The use of a rotary vertical elevator can shorten the connection distance between adjacent crushing equipment in the sand and gravel aggregate production line by at least 65%, reduce the floor space by more than 5 times, significantly reduce the investment in the production line, and make it easier to carry out closed dust removal treatment in the production line. The energy consumption of dust removal is significantly reduced, which provides favorable conditions for improving dust pollution and adapting to the development concept of green environmental protection. At the same time, it also greatly reduces the use of belt conveyors and reduces the investment cost of the production line. In the traditional sand and gravel aggregate production line, the materials are transported between crusher I 17 and crusher II 18 through a belt conveyor 19, which occupies a large space. Fig.18 As shown, in the present application, the crusher I 17 and the crusher II 18 are lifted and transported by a rotary vertical elevator 20, which occupies a small area. Fig.19 As shown, through Fig.18 and Fig.19 By comparison, it can be seen that the use of the present invention can greatly save space resources.

[0074] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.
