TECHNICAL FIELD

[0001] The present application relates to the technical field of pellet lifting, in particular to a pellet lifting device. BACKGROUND

[0002] The bucket elevator is a continuous conveying machine for vertically lifting materials, which uses a series of hoppers uniformly fixed on a endless traction member to vertically lift materials.

[0003] For example, the application number CN202111556270.7 proposes a new type of high-efficiency belt bucket elevator with controllable tension and circulating feeding, wherein the bucket elevator head wheel, the bucket elevator tail wheel and the conveying belt all contain magnetic particles, which can increase the friction between the conveying belt, the bucket elevator head wheel and the bucket elevator tail wheel, thereby improving the carrying capacity. At the same time, the self-adaptive electromagnetic tensioning device can monitor the tension of the conveying belt in real time. Through calculation, the electromagnetic tensioning device adjusts the relative distance between the bucket elevator tail wheel and the bucket elevator head wheel to achieve the purpose of tightening the conveying belt, thereby simultaneously solving the problems of insufficient conveying height and less carrying material in the prior art, reducing the workload of on-site personnel, and greatly improving the lifting and transportation of materials.

[0004] However, during the upward movement of the bucket, a large amount of pellets may fall into the gap between the bucket and the machine body, resulting in a large force between the bucket and the machine body, affecting the stability of the connection between the bucket and the conveying belt. SUMMARY

[0005] Therefore, it is necessary to provide a pellet lifting device to solve the problem that a large amount of pellets may fall into the gap between the bucket and the machine body during the upward movement of the bucket, resulting in a large force between the bucket and the machine body, affecting the stability of the connection between the bucket and the conveying belt.

[0006] The present application provides a pellet lifting device, which comprises a bucket elevator and a material blocking conveying belt. The bucket elevator comprises a machine body, a lifting conveying belt and a plurality of buckets. The lifting conveying belt is built in the machine body and arranged in a vertical direction. The plurality of buckets are arranged in sequence along the conveying direction of the lifting conveying belt. The material blocking conveying belt is built in the side wall of the machine body and arranged vertically. The material blocking conveying belt is arranged on the side wall of the plurality of buckets moving in a vertical upward direction. The conveying direction of the side of the material blocking conveying belt close to the bucket is arranged vertically upward.

[0007] Further, the conveying speed of the material blocking conveying belt is less than the conveying speed of the lifting conveying belt.

[0008] Further, the conveying speed of the material blocking conveyor belt is equal to the conveying speed of the lifting conveyor belt.

[0009] Further, the conveying speed of the material blocking conveyor belt is greater than the conveying speed of the lifting conveyor belt.

[0010] Further, the conveying direction of the material blocking conveyor belt is parallel to the conveying direction of the lifting conveyor belt, and the material blocking conveyor belt is attached to the side of the hopper away from the material blocking conveyor belt.

[0011] Further, the conveying direction of the material blocking conveyor belt is perpendicular to the conveying direction of the lifting conveyor belt, and the material blocking conveyor belt is attached to the side of the hopper directed along the horizontal line of the lifting conveyor belt.

[0012] Further, a plurality of elastic sheets are arranged along the conveying direction of the material blocking conveyor belt, and the movement path of the plurality of elastic sheets partially overlaps the movement path of the hopper.

[0013] Further, the plurality of elastic sheets near the side of the hopper are all inclined downward away from the material blocking conveyor belt.

[0014] Further, the machine body is provided with a feeding port at the bottom of the side directed vertically upward along the lifting conveyor belt, and is provided with a discharging port at the top of the side directed vertically downward along the lifting conveyor belt, and the feeding port is provided with a feeding hopper.

[0016] Compared with the prior art, the plurality of hoppers are rotated with the lifting conveyor belt to send the pellets entering the bottom of the machine body to the position above the machine body, thereby realizing the function of lifting the pellets. During the upward movement of the hopper, the larger diameter pellets fall to the position between the hopper and the machine body. By arranging the material blocking conveyor belt along the vertical direction and attached to the side wall of the hopper, the material blocking conveyor belt replaces the machine body to bear the force of the pellets.

[0020] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1 As shown, the present invention provides a pellet lifting device, including a bucket elevator 100 and a retaining conveyor belt 200. The bucket elevator 100 includes a body 110, a lifting conveyor belt 120 and multiple buckets 130. The lifting conveyor belt 120 is built into the body 110 and is arranged vertically. The multiple buckets 130 are arranged sequentially along the conveying direction of the lifting conveyor belt 120. The retaining conveyor belt 200 is built into the side wall of the body 110 and is arranged vertically. The retaining conveyor belt 200 is arranged against the side wall of the multiple buckets 130 that move in a vertically upward direction. The conveying direction of the retaining conveyor belt 200 is vertically upward on the side of the bucket 130 it is close to.

[0022] During implementation, multiple buckets 130, along with the rotation of the lifting conveyor belt 120, transport the granules entering from the bottom of the machine body 110 to the upper position of the machine body 110, thereby realizing the function of granule lifting. During the upward movement of the buckets 130, some granules with larger diameters fall to the position between the buckets 130 and the machine body 110. By setting a material blocking conveyor belt 200 along the vertical direction and attached to the side wall of the buckets 130, the material blocking conveyor belt 200 replaces the machine body 110 in bearing the force of the granules. Under the elastic deformation of the granules, the force exerted by the granules on the buckets 130 can be reduced, avoiding the buckets 130 from shaking due to the granules and affecting the lifting conveyor belt 120.

[0023] In some embodiments, the conveying speed of the material blocking conveyor belt 200 determines its effectiveness in handling the material falling from the bin 130.

[0024] In the first embodiment, the conveying speed of the blocking conveyor belt 200 is less than the conveying speed of the lifting conveyor belt 120. At this time, the blocking conveyor belt 200 moves downward relative to the lifting conveyor belt 120, which can apply a downward force to the granules located between the two, causing the granules to move downward relative to the bucket 130 that is in contact with it.

[0025] In the second embodiment, the conveying speed of the blocking conveying belt 200 is equal to the conveying speed of the lifting conveying belt 120, at this time, the pellets between the blocking conveying belt 200 and the hopper 130 are clamped and synchronously moved upward until the position where the blocking conveying belt 200 and the hopper 130 are separated, and then the pellets are dropped back into the hopper 130, at this time, the top of the blocking conveying belt 200 should be higher than the height of the maximum position of the hopper 130 moving in the vertical direction.

[0026] In the third embodiment, the conveying speed of the blocking conveying belt 200 is greater than the conveying speed of the lifting conveying belt 120, at this time, the blocking conveying belt 200 moves upward relative to the lifting conveying belt 120, and an upward force can be applied to the pellets between the two to push the pellets clamped between the two back into the hopper 130, thereby achieving the function of preventing the pellets from being clamped.

[0027] It can be understood that no matter which of the above schemes is adopted, the function of cleaning the pellets clamped between the hopper 130 and the machine body 110 can be achieved, thereby avoiding damage to the hopper 130 and the lifting conveying belt 120 when the pellets are clamped.

[0028] The number of the blocking conveying belts 200 in the present embodiment can be multiple, which are arranged according to the positions of the hopper 130 where the pellets are easily clamped.

[0029] In one embodiment, the conveying direction of the blocking conveying belt 200 is parallel to the conveying direction of the lifting conveying belt 120, and the blocking conveying belt 200 is attached to the side of the hopper 130 away from the blocking conveying belt 200.

[0030] In another embodiment, the conveying direction of the blocking conveying belt 200 is perpendicular to the conveying direction of the lifting conveying belt 120, and the blocking conveying belt 200 is attached to the side of the hopper 130 directed by the horizontal line parallel to the lifting conveying belt 120.

[0031] In the present embodiment, three blocking conveying belts 200 are arranged, and the three blocking conveying belts 200 and the lifting conveying belt 120 form a structure surrounding the hopper 130. As shown in FIG. 2, the three blocking conveying belts 200 are arranged in parallel to each other, and the three blocking conveying belts 200 and the lifting conveying belt 120 form a structure surrounding the hopper 130. Figure 3As shown, to facilitate the synchronous operation of the three retaining conveyor belts 200 and the lifting conveyor belt 120, a motor 140 and multiple bevel gears 141 are also included. The motor 140 is mounted on the machine body 110, and its output end is connected to the drive shaft 121 of the lifting conveyor belt 120. The drive shaft 121 of the lifting conveyor belt 120 is connected to the drive shaft 220 of one of the adjacent retaining conveyor belts 200 via the bevel gears 141. The drive shaft 220 of one of the adjacent retaining conveyor belts 200 is connected to the drive shaft 220 of the retaining conveyor belt 200 on the opposite side of the lifting conveyor belt 120 via the bevel gears 141. The drive shaft 220 of the retaining conveyor belt 200 on the opposite side of the lifting conveyor belt 120 is connected to the drive shaft 220 of the other adjacent retaining conveyor belt 200 via the bevel gears 141. The conveying speed of the retaining conveyor belts 200 can be controlled by controlling the meshing ratio between the bevel gears 141.

[0032] like Figure 2 As shown, in order to improve the impact of the granules on the bucket 130 during the process, this embodiment also includes multiple elastic plates 210. The multiple elastic plates 210 are arranged sequentially along the conveying direction of the baffle conveyor belt 200, and the movement paths of the multiple elastic plates 210 partially overlap with the movement path of the bucket 130.

[0033] In one embodiment, multiple elastic sheets 210 near the bin 130 are inclined downwards in a direction away from the blocking conveyor belt 200. In this case, the conveying speed of the blocking conveyor belt 200 can be set to be greater than the conveying speed of the lifting conveyor belt 120. The elastic sheets 210 are configured to move the granules stuck between the bin 130 and the blocking conveyor belt 200 into the bin 130.

[0034] In one embodiment, a feed inlet 111 is provided at the bottom of the side of the machine body 110 facing the vertically upward movement of the lifting conveyor belt 120, and a discharge outlet 112 is provided at the top of the side of the machine body 110 facing the vertically downward movement of the lifting conveyor belt 120. A feed hopper 113 is installed at the feed inlet 111.

[0035] As the pellets in the bin 130 continuously fall and the bin 130 also receives pellets that are not received by the feed inlet 111, the pellets at the bottom of the machine body 110 continue to accumulate, which also causes the problem of material jamming. Therefore, this embodiment also includes a return assembly 300. The return assembly 300 includes a return pipe 310 and a vacuum pump 320. One end of the return pipe 310 is connected to the bottom of the machine body 110, and the other end of the return pipe 310 is connected to the feed inlet 111 via the vacuum pump 320.

[0036] Compared with the prior art, the plurality of hoppers 130 sends the pellets entering the bottom of the fuselage 110 to the position above the fuselage 110 along with the rotation of the lifting conveyor belt 120, thereby achieving the function of lifting the pellets. During the upward movement of the hopper 130, the larger-diameter pellets fall to the position between the hopper 130 and the fuselage 110. By arranging the material blocking conveyor belt 200 along the vertical direction and close to the side wall of the hopper 130, the material blocking conveyor belt 200 replaces the fuselage 110 to bear the force of the pellets. Under the elastic deformation of the pellets, the force applied by the pellets to the hopper 130 can be reduced, and the shaking of the hopper 130 caused by the pellets is avoided, thereby affecting the lifting conveyor belt 120.

[0037] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
