Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and in particular relates to a vibrating bucket feeder for preventing alumina agglomeration. Background Technology

[0002] Bucket feeders, also known as bucket elevators, are a widely used continuous conveying equipment for vertical or steeply inclined conveying of powdery, granular, and small lump materials.

[0003] In the operation of a traditional bucket elevator, material enters the bottom of the casing through the feed pipe, and is then scooped up and conveyed upwards by a conveyor belt or chain. However, this method can easily lead to some material accumulating at the bottom of the casing for a long time, especially for materials that are prone to caking (such as alumina), posing a high risk of caking.

[0004] Therefore, we proposed a vibrating bucket feeder to prevent alumina agglomeration. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vibrating bucket feeder for preventing alumina agglomeration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vibrating bucket feeder for preventing alumina agglomeration includes:

[0008] The base has a housing fixedly mounted on its top end, a feed pipe fixedly connected to one side of the bottom end of the housing, and a discharge pipe fixedly connected to one side of the top end of the housing.

[0009] Two rotating shafts rotatably pass through the inner walls of both sides of the housing, and a conveyor belt is driven between the two rotating shafts. Multiple evenly distributed hoppers are fixed on the outer wall of the conveyor belt, and an infrared sensor is fixed on one inner wall of the housing.

[0010] The second cylinder is fixed to the inner wall of one side of the housing. One end of the piston rod of the second cylinder slides through the housing and is fixed with a mounting plate. Multiple through holes are opened on one side of the mounting plate.

[0011] The drive mechanism, located on one side of the top of the housing, is used to provide drive for the rotating shaft.

[0012] In one possible design, the drive mechanism includes a servo motor and a protective cover fixed to one side of the top of the housing. One end of the output shaft of the servo motor and one end of one of the rotating shafts are connected by a chain and a sprocket drive, with both the chain and the sprocket located inside the protective cover.

[0013] In one possible design, a vibration motor is fixed to one outer wall of the feed pipe, and a first mounting bracket is fixed to the inner wall of the feed pipe. The first mounting bracket includes a fixing frame, and multiple vertically staggered connecting rods are welded to the inner side of the fixing frame.

[0014] In one possible design, the bottom end of the discharge pipe is fixed to a connecting pipe by bolts, and at least one second mounting bracket is fixed to the inner wall of the connecting pipe.

[0015] In one possible design, a first cylinder is fixedly mounted on one outer wall of the housing, and an adjusting plate is slidably connected to one inner wall of the feed pipe. One end of the piston rod of the first cylinder is fixed to the top of the adjusting plate.

[0016] In one possible design, the bottom of the housing is fixedly connected to a discharge pipe, the bottom end of the discharge pipe is threaded with a sealing cap, and the outer wall of the housing has multiple inspection ports, one side of which is fixed with a baffle by bolts.

[0017] In this application, during use, a servo motor is started to drive the rotating shaft to rotate, which in turn drives the conveyor belt to rotate, thereby moving the hopper. According to the operating power of the servo motor (i.e., the moving speed of the hopper), the first cylinder is started to drive the adjusting plate to move, adjusting the flow rate of material from the feed pipe into the housing. Then, the vibration motor is started. When the material is put into the feed pipe, the vibration motor drives the feed pipe and the first mounting frame to vibrate, thereby initially breaking up the material. The material passes through the first mounting frame and flows into the bottom of the housing along the feed pipe. Under the real-time monitoring of the infrared sensor, the second cylinder drives the mounting plate to pass back and forth through the space between the two hoppers. The mounting plate moves the material, and at the same time, under the action of the through hole, some material passes through the through hole, thus playing a role in breaking up the material accumulated at the bottom. The moving hopper scoops up some material and moves it upward. When the material reaches the top, under the action of centrifugal force and inertia, the material is thrown into the discharge pipe. Under the further breaking up by the second mounting frame, the material is discharged from the connecting pipe. The material is broken up three times in total, effectively reducing the possibility of material agglomeration.

[0018] Beneficial effects: In this utility model, the vibrating bucket feeder for preventing alumina agglomeration can monitor the position of the bucket in real time through the setting of the second cylinder, mounting plate and other structures, and control the mounting plate to shuttle back and forth in the space between two adjacent buckets, to stir and disperse the material at the bottom of the shell, to avoid the material accumulating at the bottom and agglomerating, to ensure the accuracy of the movement of the mounting plate, and to avoid collisions between structures.

[0019] In this invention, the vibrating bucket feeder for preventing alumina agglomeration, through the arrangement of a first mounting frame, a vibrating motor, and a second mounting frame, allows for initial dispersion of materials when they enter the feed pipe, and further dispersion of materials when they are discharged from the discharge pipe using the second mounting frame, thereby further reducing the possibility of material agglomeration.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] In one embodiment: Refer to Figures 1-5 The bucket elevator includes: a base 1, which is placed horizontally on a flat working surface, with a housing 2 fixedly installed at its top. The housing 2 is a hollow cuboid structure, providing installation space and protection for the internal moving parts. One side of the bottom of the housing 2 is fixedly connected to the feed pipe 3 for easy material feeding; one side of the top of the housing 2 is fixedly connected to the discharge pipe 4, which extends at an angle away from the housing 2 to ensure smooth material discharge. A vibration motor is fixedly installed on one side of the outer wall of the feed pipe 3 by bolts. The output end of the vibration motor is tightly fitted to the outer wall of the feed pipe 3, and can drive the feed pipe 3 to generate high-frequency vibration after startup. A first mounting frame 5 is fixedly installed on the inner wall of the feed pipe 3. The first mounting frame 5 consists of a fixed frame and multiple connecting rods. The fixed frame is fixed to the inner wall of the feed pipe 3 by welding, and the connecting rods are vertically and alternately welded to the inner side of the fixed frame to form a grid structure. The size of the mesh is adapted to the particle size of the alumina material to be processed, which does not affect the normal passage of the material and can play a role in initially breaking up agglomerates. The first cylinder 7 is fixedly installed on one side of the outer wall of the housing 2, and the adjusting plate 6 is slidably connected to one side of the inner wall of the feed pipe 3. The top of the adjusting plate 6 is fixed to one end of the piston rod of the first cylinder 7 by bolts. The size of the adjusting plate 6 matches the cross-section of the inner wall of the feed pipe 3, and it can slide up and down along the inner wall of the feed pipe 3 under the drive of the first cylinder 7, thereby changing the flow cross-sectional area inside the feed pipe 3 and realizing the adjustment of the material flow rate.

[0031] Two rotating shafts 8 rotatably pass between the inner walls of both sides of the housing 2. The two shafts 8 are horizontally parallel and located at the upper and lower ends of the housing 2, respectively. The two ends of the shafts 8 are rotatably connected to the inner walls of the housing 2 via bearings, ensuring flexible rotation. A conveyor belt 9, made of wear-resistant rubber, is tightly wrapped around the outer walls of the two shafts 8, driving the conveyor belt 9 in a cyclical motion through the rotation of the shafts 8. Multiple evenly distributed hoppers 10 are bolted to the outer wall of the conveyor belt 9. The hoppers 10 have an open structure, with a fixed gap between adjacent hoppers 10 to ensure smooth passage of the mounting plate 13. An infrared sensor 11 is fixedly installed on one inner wall of the housing 2, with its detection direction facing the hoppers 10 on the conveyor belt 9. This sensor can monitor the position and movement of the hoppers 10 in real time and transmit the detection signal to the control terminal, facilitating control of the second cylinder 12.

[0032] The second cylinder 12 is fixedly installed on the inner wall of one side of the housing 2, and is located below the infrared sensor 11. One end of the piston rod of the second cylinder 12 slides through the side wall of the housing 2 and extends into the interior of the housing 2. The extended end of the piston rod is fixedly installed with a mounting plate 13 by bolts. Multiple through holes are evenly distributed on one side of the mounting plate 13, which can allow some material to pass through and can also break up clumps of material by the action of the mounting plate 13. The bottom of the housing 2 is fixedly connected to the discharge pipe 14, which is set vertically downward. Its bottom end is connected to the sealing cap 15 by threads. When the equipment is stopped or when it is necessary to clean the residual material inside the housing 2, the sealing cap 15 can be unscrewed to discharge the residual material through the discharge pipe 14. Multiple inspection ports 20 are opened on the outer wall of the housing 2. The positions of the inspection ports 20 correspond to the key components inside the housing 2. A baffle is fixedly installed on one side of the inspection port 20 by bolts. The baffle can seal the inspection port 20 to prevent material leakage and dust from entering. When it is necessary to repair the internal components, the baffle can be removed for operation.

[0033] This application can be used in the field of material conveying, or in other fields applicable to this application.

[0034] In another embodiment: a vibrating bucket feeder for preventing alumina agglomeration, which is applied to the field of material conveying. The structure of this embodiment is basically the same as the aforementioned embodiment, except that:

[0035] In one aspect of this embodiment, a drive mechanism is disposed on one side of the top of the housing 2 to provide driving power to the rotating shaft 8. The drive mechanism includes a servo motor 16 and a protective cover 17. Both the servo motor 16 and the protective cover 17 are fixedly mounted on one side of the top of the housing 2 by bolts. The output shaft of the servo motor 16 faces the rotating shaft 8. A sprocket is fixedly mounted on one end of the output shaft of the servo motor 16 and one end of one of the rotating shafts 8. A chain is connected between the two sprockets. The chain and the sprockets are located inside the protective cover 17. The protective cover 17 can prevent dust and debris from entering the transmission structure and avoid safety hazards caused by operators contacting moving parts. The bottom end of the discharge pipe 4 is fixedly connected to the connecting pipe 18 by bolts. The connecting pipe 18 is coaxially arranged with the discharge pipe 4. At least one second mounting bracket 19 is fixedly mounted on the inner wall of the connecting pipe 18. The structure of the second mounting bracket 19 is similar to that of the first mounting bracket 5, consisting of a fixed frame and vertically intersecting connecting rods. It is fixed to the inner wall of the connecting pipe 18 by welding to further disperse the passing material.

[0036] During operation: First, the servo motor 16 is started. The output shaft of the servo motor 16 drives the corresponding sprocket to rotate, which in turn drives one of the rotating shafts 8 to rotate via chain transmission. This rotating shaft 8 drives another rotating shaft 8 to rotate synchronously via the conveyor belt 9, thereby realizing the cyclical movement of the conveyor belt 9. The conveyor belt 9 drives the hopper 10 on the outer wall to move continuously. The moving speed of the hopper 10 is determined according to the operating power of the servo motor 16. The first cylinder 7 is started by the control terminal. The piston rod of the first cylinder 7 extends and retracts, causing the adjusting plate 6 to slide up and down along the inner wall of the feed pipe 3, adjusting the flow cross-sectional area inside the feed pipe 3, thereby controlling the flow rate of material from the feed pipe 3 into the housing 2, ensuring that the material supply matches the conveying capacity of the hopper 10, and avoiding excessive material accumulation or insufficient supply.

[0037] The vibration motor is then started, generating high-frequency vibrations that are transmitted to the feed pipe 3 and the first mounting frame 5. When alumina material is fed from the top of the feed pipe 3, it flows downwards under gravity. As it passes the first mounting frame 5, the vibrating connecting rod initially breaks up any clumps in the material. Simultaneously, the mesh structure blocks and breaks up larger clumps. The pre-processed material passes through the mesh of the first mounting frame 5 and flows down the inner wall of the feed pipe 3 into the bottom of the housing 2. During the movement of the hopper 10, the infrared sensor 11 monitors the position of the hopper 10 in real time and sends a signal to the control terminal. The control terminal controls the piston rod of the second cylinder 12 to extend and retract, causing the mounting plate 13 to move back and forth within the space between the two hoppers 10. During the movement, the mounting plate 13 contacts and agitates the material accumulated at the bottom of the housing 2, dispersing the accumulated material. At the same time, some material passes through the through holes on the mounting plate 13 under gravity, further dispersing the material and effectively preventing it from accumulating and clumping at the bottom of the housing 2 for a long time.

[0038] As the conveyor belt 9 continues to move, the moving hopper 10 scoops up some of the dispersed material at the bottom of the housing 2 and moves upward with the conveyor belt 9. When the hopper 10 reaches the top of the conveyor belt 9, its direction of movement changes, and the material is thrown out of the hopper 10 under the combined action of centrifugal force and inertia, falling into the discharge pipe 4 on one side of the top of the housing 2. The material flows downward in the discharge pipe 4, and when it passes through the connecting pipe 18, the second mounting bracket 19 on the inner wall of the connecting pipe 18 disperses the material again, completely dispersing any small pieces of material that may re-aggregate during the conveying process. Finally, the material is discharged from the connecting pipe 18, completing the entire feeding and anti-caking process.
