Description

Technical Field

[0001] This utility model belongs to the field of feeder technology, specifically relating to a novel rod-type feeder. Background Technology

[0002] In aluminum electrolysis plants, the feeder, vertically installed above the aluminum electrolysis cell, is the main equipment for supplying raw materials for aluminum electrolysis production, primarily responsible for supplying production materials. The feeder's structure includes a cylinder, cylinder seat, column tie rod, upper bell jar, feed cylinder, fork joint, and lower bell jar. Its principle is that the piston rod of the cylinder drives the lower bell jar to open and close intermittently. When the lower bell jar seals the feed cylinder and the feed cylinder is in a closed state, alumina material from the external material box automatically falls into the feed cylinder. When the upper bell jar seals the feed cylinder and the feed cylinder is in an open state, the alumina material in the feed cylinder automatically falls into the electrolysis cell, ensuring the supply of raw materials during the aluminum electrolysis production process. The authorized document with publication number CN220079216U discloses a brushless constant-volume feeder for aluminum electrolysis; the structure and principle of the constant-volume feeder are existing technologies.

[0003] The feeder stores alumina material in its feed cylinder. When the alumina material particles are too fine or absorb moisture and clump together, they will block the cavity of the feed cylinder or adhere to the inner wall of the feed cylinder. They will accumulate and bridge in the cavity or outlet of the feed cylinder, thus affecting the flowability of the material. The feeder does not have a design to vibrate the material in the feed cylinder, which is a shortcoming.

[0004] Existing feeders have a design flaw where the feeder does not vibrate the material inside the feeder when storing alumina material. To address this issue, this application proposes a novel rod-type feeder. Utility Model Content

[0005] The purpose of this utility model is to provide a novel rod-type feeder to solve the problem mentioned in the background art of the design of the feeder without vibrating the material in the feed cylinder.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5This utility model provides a technical solution: a novel rod-type feeder, comprising a feeder body, including a cylinder seat 11, an adjusting cylinder 12, an upper fork joint 13, a column pull rod 14, an upper bell housing 15, a lower fork joint 18, a lower bell housing 17, a guide rod 2, and a material cylinder 16. The adjusting cylinder 12 is fixed to the cylinder seat 11 by bolts, and the piston rod of the adjusting cylinder 12 is fixed to the upper fork joint 13 by bolts. The column pull rod 14 is fixed to the upper fork joint 13 and the lower fork joint 18 by pins. The lower fork joint 18 is fixed to the lower bell housing 17 by pins. The upper bell housing 15 is welded to the column pull rod 14. The guide rod 2 is connected to the cylinder... The seat 11 and the material cylinder 16 are fixed with screws; the guide cylinder 8 is installed inside the material cylinder 16 and is fixed to the material cylinder 16 with glue. The inner surface of the guide cylinder 8 is an inclined slope surface. The material entering the material cylinder 16 is guided by the inclined surface of the guide cylinder 8 to flow towards the axial position of the material cylinder 16, so that the flowing material flows towards the surface of the sealing disc 44; the vibrating assembly includes the sealing disc 44 installed on the lower fork joint 18, the flow-aiding air disc 43 fixedly connected to the sealing disc 44, the internally connected air pipe 41 and the diversion ring pipe 42. The sealing disc 44 and the lower bell jar 17 are designed as a double-layer sealing design to avoid material leakage. Furthermore, the sealing disc 44 receives material. During material feeding, driven by the piston rod of the adjusting cylinder 12, the column pull rod 14, the lower fork joint 18, and the lower bell jar 17 move vertically downwards, opening the bottom of the material cylinder 16. The material inside the material cylinder 16 flows down. When material adheres to and accumulates on the surface of the sealing disc 44, the flow-aiding air disc 43 vibrates and blows air under the action of external compressed air, causing the sealing disc 44 to vibrate, thus breaking the arch and facilitating the flow of material. The blowing volume of the flow-aiding air disc 43 is related to factors such as working pressure and air consumption, and can be set according to specific conditions during actual use. The airflow-assisted disc 43 is adjusted to meet usage requirements, preventing material from escaping over a large area due to airflow. The deformation component includes a fixed pull rod 5, whose top end is fixedly connected to the upper bell jar 15, and a spring steel wire 9 connected to the bottom end of the fixed pull rod 5. The other end of the spring steel wire 9 is fixedly connected to the guide cylinder 8. A flow-dividing ring 6 is fixed on the fixed pull rod 5. When the column pull rod 14 moves down under the action of the piston rod of the adjusting cylinder 12, the fixed pull rod 5 acts on the spring steel wire 9, causing the spring steel wire 9 to deform and twist under force. The twisted spring steel wire 9 disturbs the material inside the material cylinder 16, causing the material to move and facilitating material flow.

[0028] In this embodiment, a guide plate 3 is fixed on the outer side of the guide rod 2, and the column tie rod 14 passes through the guide plate 3. The guide plate 3 plays a limiting role, preventing the column tie rod 14 from tilting and allowing the column tie rod 14 to slide in a predetermined direction.

[0029] In this embodiment, the top surface of the material cylinder 16 is provided with a feed inlet that cooperates with the upper bell jar 15, and the bottom surface of the material cylinder 16 is provided with a discharge outlet that corresponds to the lower bell jar 17. When the feed inlet of the material cylinder 16 is open and the discharge outlet is closed, it is convenient for the material to enter the interior of the material cylinder 16. When the feed inlet of the material cylinder 16 is closed and the discharge outlet is open, it is convenient for the material inside the material cylinder 16 to fall. The guide cylinder 8 is fixed to the inner surface of the material cylinder 16 by screws, and the guide cylinder 8 plays the role of guiding the direction of the material.

[0030] In this embodiment, the guide cylinder 8 includes an upper conical cylinder c and a lower conical cylinder d. The top end of the upper conical cylinder c has a wide diameter and the bottom end has a narrow diameter. The top end of the lower conical cylinder d has a wide diameter and the bottom end has a narrow diameter. The edge of the sealing disk 44 fits against the wide diameter surface of the lower conical cylinder d. The surface of the guide cylinder 8 has a slope. The material falls along the slope, causing the material to concentrate and fall onto the surface of the sealing disk 44.

[0031] In this embodiment, the spring steel wire 9 includes a bent part and a wavy part. One end of the bent part is a ball. The bottom end of the fixed pull rod 5 is fixedly connected to the ball end of the bent part by welding. One end of the wavy part is fixedly connected to the inner surface of the upper conical cylinder c. The spring steel wire 9 has the functions of elasticity and reset. When the spring steel wire 9 is subjected to force, it will twist. The twisting of the spring steel wire 9 will disturb the material, which is conducive to the falling movement of the material.

[0032] In this embodiment, the sealing disc 44 is umbrella-shaped, and the surface of the sealing disc 44 is provided with uniformly distributed flow grooves 441, which concentrate the material in the flow grooves 441 and facilitate the concentrated falling of the material. The surface of the lower bell jar 17 is embedded with uniformly distributed metal spring plates 171. A tension spring 7 is fixed between the sealing disc 44 and the metal spring plates 171. The metal spring plates 171 and the lower bell jar 17 are glued together. The two ends of the tension spring 7 are respectively embedded in the interior of the sealing disc 44 and the metal spring plates 171. When the sealing disc 44 vibrates under the action of the flow-aiding air disc 43, the tension spring 7 and the metal spring plates 171 vibrate at a micro level, which facilitates the flow of material.

[0033] Working principle and usage process of this utility model:

[0034] The operation of the regulating cylinder 12 causes the piston rod of the regulating cylinder 12 to drive the upper fork joint 13, the column pull rod 14, the upper bell jar 15, the lower fork joint 18, and the lower bell jar 17 to open and close intermittently. When the lower bell jar 17 blocks the material cylinder 16 and the material cylinder 16 is in a closed state, the alumina material in the external material box is automatically released into the material cylinder 16. When the upper bell jar 15 blocks the material cylinder 16 and the material cylinder 16 is in an open state, the alumina material in the material cylinder 16 is automatically released into the electrolytic cell, ensuring the supply of raw materials during the electrolytic aluminum production process.

[0035] During the feeding process of the above-mentioned material cylinder 16, the material entering the material cylinder 16 is guided by the guide cylinder 8. The surface of the guide cylinder 8 has a slope, and the material falls down along the slope, causing the material to concentrate and fall onto the surface of the sealing plate 44.

[0036] When material adheres to and accumulates bridging inside the material cylinder 16 and on the surface of the sealing plate 44, the flow-assisting air disc 43 vibrates and blows air under the action of external compressed air, causing the sealing plate 44 to vibrate, which has the effect of breaking the arch, facilitating the flow of material and avoiding material accumulation and blockage.

[0037] When the sealing disc 44 vibrates under the action of the flow-aiding disc 43, it pulls the spring 7 and the metal spring plate 171 to vibrate at a small level, which is conducive to material flow.

[0038] When the bottom of the material cylinder 16 is open and the lower bell jar 17 moves down, the material on the surface of the sealing plate 44 falls.

[0039] Driven by the piston rod of the regulating cylinder 12, when the column tie rod 14 moves down, the fixed tie rod 5 acts on the spring steel wire 9. The spring steel wire 9 is deformed and twisted under force. The twisted spring steel wire 9 disturbs the material inside the material cylinder 16, causing the material to move and facilitating the flow of the material.

[0040] In summary: The feeder is designed with a vibrating cylinder 16 for the material inside. The air-assisted disc 43 vibrates and blows air, causing the sealing disc 44 to vibrate, which has the effect of breaking the arch. The spring steel wire 9 is deformed and twisted under force. The twisted spring steel wire 9 disturbs the material inside the cylinder 16, which is conducive to the material flowing down and avoids the accumulation and blockage of material.

[0041] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
