Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, specifically relating to a ladle casting residue tailings pellet dryer. Background Technology

[0002] Steel ladle casting residue is a spherical material made from steel ladle casting residue. In the steel production process, after the steel ladle is finished casting, a certain amount of molten steel and slag will remain. These residual molten steel and slag are called steel ladle casting residue. It not only helps with resource recycling and environmental protection, but also plays an important role in steel production.

[0003] In the process of preparing ladle casting residue tailings pellets, the ladle casting residue tailings fine powder, bauxite powder, aluminum powder and pellet binder are first mixed evenly in a certain proportion; then, pellets are made using a pelletizing machine and other equipment; the pellets are then dried to remove excess moisture; finally, the pellets are screened using screening equipment to remove unqualified products.

[0004] However, during the drying process, if the drying temperature is too low, the moisture in the pellets will not evaporate completely; but if the drying temperature is too high, the moisture inside the pellets will evaporate rapidly, causing an increase in internal pressure, which in turn will lead to the pellets breaking. Therefore, a steel ladle casting residue tailings pellet dryer is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ladle casting residue tailings pellet dryer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ladle casting residue tailings pellet dryer, comprising:

[0007] The main body of the equipment includes an outer shell, mounting plates, a loading cylinder, and partitions. The outer shell has a rectangular cross-section. Multiple mounting plates are installed inside the outer shell, with each mounting plate having the same distance from the inner walls of the outer shell. The loading cylinder is slidably mounted on the side wall of the mounting plate away from the outer shell. Multiple partitions are fixedly mounted on the inner wall of the loading cylinder, with each partition having the same distance from the inner wall of the loading cylinder. Both the mounting plates and the loading cylinder are made of thermally conductive material.

[0008] A drying assembly includes heating wires, which are corrugated and arranged in multiple groups. Each group of heating wires is installed between each mounting plate and the outer casing, and the length of each group of heating wires gradually increases.

[0009] As a preferred embodiment, the main body of the equipment further includes a mounting frame, and the drying assembly further includes a turntable and a rotating motor. Two turntables are provided, and the two turntables are respectively installed at both ends of the outer casing. The turntables are rotatably installed on the mounting frame, and the rotating motor is installed on the mounting frame, with the output shaft of the rotating motor connected to the turntable.

[0010] As a preferred embodiment, the main body of the equipment further includes a connecting plate, a sealing plate, and a connecting column. The connecting plate is vertically installed near the opening of the partition. The sealing plate is placed at the opening of the loading cylinder. One end face of the connecting plate has a connecting cylinder. One end face of the sealing plate has a mounting hole adapted to the connecting column. The connecting column is threaded to the connecting cylinder. The sealing plate has a mounting groove on one end face near the connecting plate. One end of the partition is inserted into the mounting groove.

[0011] As a preferred embodiment, the mounting plate has a first heat dissipation hole, the partition has a second heat dissipation hole, and multiple first heat dissipation holes and multiple second heat dissipation holes are provided, with the multiple first heat dissipation holes and multiple second heat dissipation holes distributed at intervals.

[0012] As a preferred embodiment, the device body further includes a handle, which is mounted on the end of the connecting column away from the connecting cylinder, and the handle is located outside the partition.

[0013] As a preferred embodiment, one of the turntables has a discharge port that is adapted to the loading cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a drying assembly comprising heating wires arranged in a corrugated shape. Multiple sets of heating wires are arranged, each set installed between a mounting plate and a housing, with the length of each set gradually increasing. Initially, the shortest heating wire is located at the bottom. Under gravity, the pellets adhere to the bottommost partition, and the heat generated by the heating wires is transferred to the pellets via the mounting plate and the loading cylinder. After the shortest heating wire is energized for a predetermined time, a rotating motor drives a turntable to rotate until a slightly longer heating wire is located at the bottom. Under gravity, the pellets roll above this heating wire. This process continues, with the pellets being successively heated and dried by multiple heating wires of gradually increasing length. This gradual increase in the drying temperature of the pellets prevents sudden excessive temperature rises that could cause rapid evaporation of moisture inside the pellets, reducing the probability of pellet breakage.

[0016] This invention comprises a connecting plate, a sealing plate, and a connecting column. The connecting plate is vertically installed near the opening of the partition, and the sealing plate is placed at the opening of the loading cylinder. One end face of the connecting plate has a connecting cylinder, and one end face of the sealing plate has an installation hole adapted to the connecting column. The connecting column and the connecting cylinder are threaded together. The sealing plate has an installation groove on the end face near the connecting plate, and one end of the partition is inserted into the installation groove. After the drying process is completed, the user pulls the handle, which in turn pulls the loading cylinder, the partition, and the pellets out through the discharge port. Then, the handle is rotated to disconnect the threaded connection between the connecting column and the connecting cylinder connected to the handle. The dried pellets can then be removed by taking out the connecting plate. The operation is simple. Attached Figure Description

[0028] The drying assembly 2 includes a heating wire 21, which is corrugated and has multiple sets. Each set of heating wires 21 is installed between each mounting plate 12 and the outer casing 11, and the length of each set of heating wires 21 gradually increases.

There are two turntables 22, which are respectively installed at both ends of the outer shell 11. The turntables 22 are rotatably installed on the mounting frame 15. The rotating motor 23 is installed on the mounting frame 15, and the output shaft of the rotating motor 23 is connected to the turntable 22.

[0030] The main body of the equipment 1 also includes a connecting plate 16, a sealing plate 17, and a connecting column 18. The connecting plate 16 is vertically installed near the opening of the partition 14. The sealing plate 17 is placed in the opening of the loading cylinder 13. One end face of the connecting plate 16 has a connecting cylinder 161. One end face of the sealing plate 17 has a mounting hole 171 that matches the connecting column 18. The connecting column 18 is threadedly connected to the connecting cylinder 161. The sealing plate 17 has a mounting groove 172 on one end face near the connecting plate 16. One end of the partition 14 is inserted into the mounting groove 172.

[0031] The mounting plate 12 has a first heat dissipation hole 121, and the partition plate 14 has a second heat dissipation hole 141. Multiple first heat dissipation holes 121 and multiple second heat dissipation holes 141 are provided, and the multiple first heat dissipation holes 121 and multiple second heat dissipation holes 141 are distributed at intervals.

[0032] The main body of the equipment 1 also includes a handle 19, which is installed at the end of the connecting column 18 away from the connecting cylinder 161, and the handle 19 is located outside the partition 14;

[0033] One of the turntables 22 has a discharge port 221, which is adapted to the loading cylinder 13.

[0034] Working principle and usage process of this utility model:

[0035] In the initial state, the steel ladle casting residue tailings pellets to be dried are placed between the charging cylinder 13 and the partition 14, with the shortest heating wire 21 located at the bottom. Under the action of gravity, the pellets adhere to the bottom partition 14. At this time, the heat generated by the heating wire 21 is transferred to the pellets through the mounting plate 12 and the charging cylinder 13, thereby realizing the drying function of the pellets.

[0036] After the shortest heating wire 21 is energized for a predetermined time, the starting rotary motor 23 drives one of the turntables 22 to rotate, which in turn drives the main body of the equipment 1 to rotate until the slightly longer heating wire 21 is at the bottom. Similarly, under the action of gravity, the pellets roll to the top of the heating wire 21. The heat generated by the energized heating wire 21 is transferred to the pellets through the mounting plate 12 and the loading cylinder 13. In this way, the pellets are heated and dried by multiple heating wires 21 of gradually increasing length. In this way, the drying temperature of the pellets gradually increases to prevent the temperature from suddenly becoming too high and causing the moisture inside the pellets to evaporate too quickly, thus reducing the probability of pellet breakage.

[0037] After the drying process is completed, the user pulls the handle 19, which in turn pulls the loading cylinder 13, the partition plate 14 and the pellets out through the discharge port 221; then rotate the handle 19 to disconnect the threaded connection between the connecting column 18 connected to the handle 19 and the connecting cylinder 161, and then take out the connecting plate 16 to take out the dried pellets. The operation is simple.

[0038] Although embodiments of the present invention have been shown and described, 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.
