Description

Technical Field

[0001] This utility model belongs to the field of cooling block electrode paste prepared from carbon raw materials, and relates to a device for cooling electrode paste. Background Technology

[0002] Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode. It is baked by the heat in the submerged arc furnace. The current is input into the furnace through the electrode to generate an electric arc for smelting. The electrode plays an extremely important role in the entire electric furnace. Without it, the electric furnace cannot function. In order for the electrode to work normally at the temperature generated by the electric arc, it must have high oxidation resistance and conductivity. Only electrodes made of carbon materials have these properties, because carbon electrodes can withstand electric arc temperatures of up to 3500℃ and only slowly oxidize.

[0003] The electrode paste height refers to the height from the top of the electrode clamp to the top of the electrode paste. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to stratification, or the electrode cylinder may be damaged due to excessive paste column pressure. If the electrode paste column is too low, the filling performance will be poor due to insufficient paste column pressure, making it difficult to obtain a dense electrode. A suitable electrode paste column height is beneficial to improving the quality of electrode calcination and reducing consumption. If the particle size is too large, electrode paste suspension failure is likely to occur; if the particle size is too small, paste spraying is likely to occur. In order to ensure the quality of the electrode paste, strict control is required during the preparation process. Existing electrode paste preparation processes require cooling treatment. Natural cooling is too slow, while water cooling is too fast. Both too fast and too slow cooling methods can easily affect the quality of the electrode paste. Therefore, in order to solve the above technical problems, the technical solution of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a device for cooling electrode paste, thereby solving the aforementioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A device for cooling electrode paste includes horizontally arranged support frames, with horizontally arranged roller conveyors connected between the support frames. Airflow gaps are provided between adjacent rollers on the roller conveyor. Block-shaped electrode paste is conveyed from the feed end to the discharge end of the roller conveyor along the upper surface of the rollers. A first cooling structure is connected to the top of the support frames, with cooling ends on both sides of the first cooling structure inclined downwards and facing the electrode paste on both sides of the roller conveyor. A second cooling structure is connected to the bottom of the support frames, with cooling ends on both sides of the second cooling structure inclined upwards and facing the electrode paste on both sides of the roller conveyor. Several third cooling structures are also connected to the top of the support frames, arranged sequentially along the roller conveyor, with the cooling ends of the third cooling structures facing the top of the electrode paste.

[0007] The working principle of this invention is as follows: When cooling is required during the preparation of the electrode paste, the electrode paste is placed on a roller conveyor. The gaps between the rollers facilitate natural heat dissipation of the electrode paste. Simultaneously, the roller conveyor moves the electrode paste, and during this movement, a first, second, and third cooling structure works in conjunction to lower the temperature. All three structures employ air-cooling, which allows for gradual cooling of the electrode paste, faster than natural cooling and avoiding the rapid cooling problem associated with water cooling. Furthermore, the combined use of these three cooling structures ensures even cooling of all surfaces of the electrode paste, achieving thorough and uniform cooling. This solves the problem of difficulty in cooling the electrode paste at a moderate speed and also addresses the challenge of maintaining electrode paste quality during the cooling process.

[0008] Furthermore: the first cooling structure includes a vertically arranged first support plate, the two sides of the first support plate are respectively connected to the top of the two sides of the support frame, the first support plate is provided with an opening groove for electrode paste to pass through, the two sides of the first support plate are respectively provided with a first drive motor, the first drive motor is internally connected to a first drive shaft, and the front end of the first drive shaft is connected to a first blade group.

[0009] Furthermore: the first drive motor is connected to the first support plate by a number of first support rods, there is a gap between the heat dissipation end of the first drive motor and the first support plate, and the number of first support rods are arranged around the outer wall of the first drive motor in sequence.

[0010] Furthermore: the height of the top of both sides of the support frame is greater than the height of the top of the roller.

[0011] Furthermore: the second cooling structure includes a vertically arranged second support plate, the two sides of the second support plate are respectively connected to the bottom of the two sides of the support frame, the two sides of the second support plate are respectively provided with a second drive motor, the interior of the second drive motor is connected to a second drive shaft, and the front end of the second drive shaft is connected to a second blade group.

[0012] Furthermore: the second drive motor is connected to the second support plate by a number of second support rods, there is a gap between the heat dissipation end of the second drive motor and the second support plate, and the number of second support rods are arranged around the outer wall of the second drive motor in sequence.

[0013] Furthermore: the third cooling structure includes an inverted U-shaped frame, with the bottom sides of the U-shaped frame connected to the top of the two sides of the support frame respectively, and a blower connected to the top of the inner wall of the U-shaped frame, with the air outlet of the blower facing the top surface of the electrode paste.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. A device for cooling electrode paste, wherein a first cooling structure, a second cooling structure, and a third cooling structure are combined to facilitate air-blowing cooling of all surfaces of the electrode paste, so that the entire electrode paste achieves sufficient and uniform cooling, thereby ensuring the quality of the electrode paste during the cooling process.

[0016] 2. In this utility model, a roller conveyor is used to drive the electrode paste to move. During the movement, the gaps between the rollers facilitate the natural heat dissipation of the electrode paste. At the same time, during the movement, the electrode paste gradually comes into contact with the first cooling structure, the second cooling structure, and the third cooling structure, so that the electrode paste can achieve the purpose of cooling at a moderate speed.

[0023] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0024] Example 1

[0025] This utility model discloses a device for cooling electrode paste, such as... Figure 1As shown, the system includes a horizontally arranged support frame 1, with horizontally arranged roller conveyors 2 connected between the support frames 1. Airflow gaps are provided between adjacent rollers 3 on the roller conveyor 2. Block-shaped electrode paste is conveyed along the feed end to the discharge end of the roller conveyor 2 from the upper surface of the rollers 3. A first cooling structure is connected to the top of the support frame 1, with cooling ends on both sides of the first cooling structure inclined downwards and facing the electrode paste on both sides of the roller conveyor 2. A second cooling structure is connected to the bottom of the support frame 1, with cooling ends on both sides of the second cooling structure inclined upwards and facing the electrode paste on both sides of the roller conveyor 2. Several third cooling structures are also connected to the top of the support frame 1, arranged sequentially along the roller conveyor 2, with the cooling ends of the third cooling structures facing the top of the electrode paste.

[0026] The specific implementation method of this embodiment is as follows: When cooling treatment is required during the preparation of electrode paste, the electrode paste is placed on a roller conveyor. The gap between the rollers facilitates the natural heat dissipation of the electrode paste. At the same time, the roller conveyor facilitates the movement of the electrode paste. During the movement, the first, second, and third cooling structures work together to cool the electrode paste. The first, second, and third cooling structures all adopt air-cooling treatment. Air cooling facilitates the gradual cooling of the electrode paste, which is faster than the natural cooling of the electrode paste and avoids the problem of rapid cooling of the entire electrode paste caused by water cooling. The cooperation of the first, second, and third cooling structures facilitates air-blowing cooling of all surfaces of the electrode paste, so that the entire electrode paste achieves sufficient and uniform cooling.

[0027] Example 2

[0028] This utility model discloses a device for cooling electrode paste, such as... Figure 1 As shown, the first cooling structure includes a vertically arranged first support plate 4.

The first drive motor 5 is internally connected to a first drive shaft 6. The front end of the first drive shaft 6 is connected to a first blade group 7.

[0029] The first drive motor 5 and the first support plate 4 are connected by several first support rods 8. There is a gap between the heat dissipation end of the first drive motor 5 and the first support plate 4. Several first support rods 8 are arranged around the outer wall of the first drive motor 5 in sequence.

[0030] The height of the top of both sides of the support frame 1 is greater than the height of the top of the roller 3.

[0031] The specific implementation method of this embodiment is as follows: the two sides of the first support plate are convenient to connect to the top of the support frame, and an opening slot is provided on the support plate to avoid affecting the movement of the electrode paste along the roller. During the movement, the electrode paste works by starting the first drive motor. The first drive motor drives the first drive shaft to rotate. During the rotation of the first drive shaft, it is convenient to drive the first blade group to rotate. The rotation of the first blade group is convenient to blow the generated wind towards the electrode paste.

[0032] Preferably, the two first drive motors are located on both sides of the first support plate and are inclined downwards, so that the wind force generated by the first blade group is mainly blown to the left and right sides and the top surface of the electrode paste.

[0033] The first support rods facilitate the fixing of the first drive motor and create a gap between the heat dissipation end of the first drive motor and the first support plate, thereby facilitating heat dissipation during the operation of the first drive motor.

[0034] Preferably, by setting the height of the top two sides of the support frame to be greater than the height of the top of the roller, it is convenient to limit the electrode paste as it moves along the roller, thus preventing the electrode paste from detaching from the roller during its movement.

[0037] The second drive motor 10 is connected to the second support plate 9 by a number of second support rods 13. There is a gap between the heat dissipation end of the second drive motor 10 and the second support plate 9. The number of second support rods 13 are arranged around the outer wall of the second drive motor 10 in sequence.

[0038] The third cooling structure includes an inverted U-shaped frame 14. The bottom sides of the U-shaped frame 14 are connected to the top of the two sides of the support frame 1, respectively. A blower 15 is connected to the top of the inner wall of the U-shaped frame 14, and the air outlet of the blower 15 is facing the top surface of the electrode paste.

[0039] The specific implementation method of this embodiment is as follows: the two sides of the second support plate are connected to the two sides of the bottom of the support frame. At the same time, the two sides of the second support plate are used to connect the second drive motor. The second drive motor is used to drive the second drive shaft to rotate. During the rotation of the second drive shaft, it is convenient to drive the second blade group to rotate. During the rotation of the second blade group, the wind force generated will blow towards the electrode paste. The wind force generated by the second blade group mainly blows towards the left and right sides and the bottom surface of the electrode paste.

[0040] The second drive motor is easily fixed by several second support rods, while also creating a gap between the heat dissipation end of the second drive motor and the second support plate, thereby facilitating heat dissipation during the operation of the second drive motor.

[0041] The two sides of the bottom of the U-shaped frame are easy to connect to the two sides of the top of the support frame, and the top of the inner wall of the U-shaped frame is easy to connect to the blower.
