Description

Technical Field

[0001] The invention belongs to the technical field of aluminum smelting equipment, and in particular relates to a burner for improving the performance of an anode carbon block baking furnace. Background Art

[0002] Anode carbon blocks refer to carbon blocks produced with petroleum coke and asphalt coke as aggregates and coal tar as binder. They can be used as anode materials for pre-baked aluminum electrolytic cells. During the processing of anode carbon blocks, they usually need to be calcined. In the existing technology, a calcination furnace is usually used for calcination, which can not only significantly reduce the sintering temperature, but also greatly reduce energy consumption.

[0003] However, the existing roasting furnaces usually have the following problems when calcining anode carbon blocks:

[0004] 1. When calcining the anode carbon block, the raw materials are usually transported to the inside of the roasting furnace and calcined by the internal burner. However, the internal burner is often fixed in one position, so that the calcination effect of the anode carbon block close to the burner is often better, and the calcination effect of the side away from the burner is often worse, which makes the calcination of the anode carbon block uneven, greatly reducing the calcination performance of the roasting furnace;

[0005] 2. Since the anode carbon blocks are often piled together for calcination in the roasting furnace, the raw materials at the bottom of the pile are easily adhered to the placement plate during the calcination process, which not only causes inconvenience for the staff to take out and clean up the materials after the calcination is completed, but also makes the anode carbon blocks above the pile insufficiently calcined and the anode carbon blocks below the pile over-calcined, reducing the production quality of the anode carbon blocks. Summary of the invention

[0006] The purpose of the present invention is to provide a burner that can greatly improve the calcination performance of the roasting furnace and avoid the raw materials from sticking to the placing plate, so as to address the problems raised in the above background technology that the calcination performance of the roasting furnace is low and the raw materials are easy to stick to the placing plate when the anode carbon blocks are calcined in the roasting furnace.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A burner for improving the performance of an anode carbon block baking furnace, comprising:

[0009] A device body, wherein a feed inlet is provided above the device body, a placement cavity is provided below the feed inlet, a placement plate is provided in the placement cavity, and a motor is provided at the bottom of the device body;

[0012] A first transmission assembly, the first transmission assembly comprises three transmission wheels and a transmission belt, the rotating rod and the two reciprocating threaded rods are in the same horizontal line and are interference-fitted with transmission wheels, and the three transmission wheels are sleeved with transmission belts;

[0013] A second transmission assembly is also provided inside the device body, and the rotating rod is controlled by the motor through the second transmission assembly.

[0014] Preferably, the second transmission assembly includes a third gear, a fourth gear and a rotating shaft. The bottom wall of the device body is rotatably connected to a rotating shaft below the first transmission assembly. The output shaft of the motor is fixedly connected to the rotating shaft. The top of the rotating shaft is interference fit with the third gear. The rotating rod is interference fit with the fourth gear at a position on the same horizontal line as the third gear, and the third gear and the fourth gear are meshed with each other.

[0015] Preferably, the radius of the third gear is one quarter of the radius of the fourth gear, so as to reduce the load of the motor.

[0016] Preferably, the side walls at the feed inlet are all inclined to facilitate the raw materials of the anode carbon blocks to enter the interior of the device body.

[0017] Preferably, a circular limiting groove is formed on the lower wall of the circular cavity, a limiting block is fixed to the bottom of the second gear, and the limiting block is slidably connected to the inner wall of the circular limiting groove to prevent the second gear from being displaced.

[0018] Preferably, the tops of the two burners are both provided with flame holes.

[0019] Preferably, sliding grooves are provided on both side walls of the device body, and the two fixed rods extend to the interior of the placement cavity through the two sliding grooves respectively, and are fixedly connected to the two sides of the placement plate, and the two fixed rods are respectively slidably connected to the inner walls of the two sliding grooves, thereby limiting the two reciprocating threaded sleeves.

[0020] Preferably, a heat dissipation shell is provided on the motor.

[0021] Compared with the existing technology, the burner for improving the performance of anode carbon block baking furnace has the following advantages:

[0022] 1. The present invention sets a roasting assembly. When the anode carbon block is calcined, the rotation of the first gear is used to drive a burner to make a circular motion. The rotation of the first gear drives the second gear to make a circular motion around the first gear, so that the second gear drives another burner to make a circular motion with a larger radius, so that the raw materials on the placement plate are evenly calcined by the two burners, which greatly improves the calcination performance of the roasting furnace.

[0023] 2. The present invention sets a first transmission component and a vibration component, so that the rotating rod drives the first gear to rotate, and at the same time drives the two reciprocating threaded rods to rotate through the first transmission component, so that the two reciprocating threaded sleeves perform reciprocating vertical displacement, and the placement plate is pulled by two fixed rods to perform reciprocating vertical displacement, so that the placement plate vibrates, thereby avoiding the raw materials on the placement plate from sticking to the placement plate. It is not only convenient for the staff to take out and clean the materials after the calcination is completed, but also the anode carbon blocks on the placement plate are evenly calcined, thereby improving the production quality of the anode carbon blocks.

[0024] 3. The present invention sets a second transmission assembly. Since the roasting assembly and the two vibration assemblies in the device body are driven by the rotating rod, it is easy to cause a huge load on the motor. The radius of the third gear fixed to the motor output shaft in the second transmission assembly is only one-fourth of the radius of the fourth gear fixed to the rotating rod. When the third gear rotates sixteen times, the rotating rod only rotates one circle, which greatly reduces the load on the motor and extends the service life of the motor.

DETAILED DESCRIPTION

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0031] like Figure 1-4 As shown, a burner for improving the performance of an anode carbon block baking furnace comprises:

[0032] The device body 1 is provided with a feed port 11 on the top of the device body 1, and the side walls at the feed port 11 are all inclined, so that the raw materials of the anode carbon block can enter the device body 1 easily, so that the raw materials can automatically slide into the device body 1 when they fall on the upper wall of the feed port 11, and a placement cavity 12 is provided below the feed port 11, and a placement plate 13 is provided in the placement cavity 12, and a motor 14 is provided at the bottom of the device body 1, and a heat dissipation shell 141 is provided on the motor 14, so as to avoid damage to the motor 14 due to excessive temperature when calcining the anode carbon block;

[0033] The roasting assembly 2 comprises a circular cavity 21, a rotating rod 22, a first gear 23, a second gear 24, a tooth groove 25 and two burners 26. The rotating rod 22 is rotatably connected inside the device body 1. The bottom wall of the placement cavity 12 is provided with a circular cavity 21. The top of the rotating rod 22 extends into the circular cavity 21 and is interference-fitted with the first gear 23. The circular cavity 21 is also provided with a second gear 24. The first gear 23 and the second gear 24 are meshed with each other. The side wall of the circular cavity 21 is provided with a tooth groove 25 that is meshed with the second gear 24. The upper walls of the first gear 23 and the second gear 24 are fixedly connected with the burners 26. The tops of the two burners 26 are provided with flame holes 261.

[0034] It is worth mentioning that when the anode carbon block is calcined, the rotating rod 22 is used to drive the rotation of the first gear 23, and then drive a burner 26 to make a circular motion. Since the two sides of the second gear 24 are meshed with the first gear 23 and the tooth groove 25, the first gear 23 will drive the second gear 24 to make a circular motion around the first gear 23 in the circular cavity 21 while rotating, so that the second gear 24 drives another burner 26 to make a circular motion with a larger radius, so that the raw materials on the placement plate 13 are evenly calcined by the two burners 26, which greatly improves the calcination performance of the roasting furnace. A circular limit groove 211 is provided on the lower wall of the circular cavity 21, and a limit block 212 is fixed at the bottom of the second gear 24. The limit block 212 is slidably connected to the inner wall of the circular limit groove 211 to prevent the second gear 24 from moving upward and causing the first gear 23 to no longer mesh with the second gear 24.

[0035] Two vibration components 3, each vibration component 3 includes a reciprocating threaded rod 31, a reciprocating threaded sleeve 32 and a fixed rod 33, the reciprocating threaded rod 31 is rotatably connected in the side wall of the device body 1, the reciprocating threaded sleeve 32 is threadedly matched on the reciprocating threaded rod 31, the reciprocating threaded sleeve 32 is fixedly connected to the fixed rod 33 on one side of the reciprocating threaded sleeve 32 close to the placement cavity 12, and the fixed rod 33 extends into the placement cavity 12 and is fixedly connected to one side of the placement plate 13;

[0036] The first transmission assembly 4 includes three transmission wheels 41 and a transmission belt 42. The rotating rod 22 and the two reciprocating threaded rods 31 are in the same horizontal line and are interference-fitted with the transmission wheels 41. The transmission belts 42 are sleeved on the three transmission wheels 41.

[0037] It should be noted that, while the rotating rod 22 rotates, the two reciprocating threaded rods 31 will be driven to rotate through the three transmission wheels 41 and the transmission belt 42, so that the two reciprocating threaded sleeves 32 perform reciprocating vertical displacement, and the two fixed rods 33 will pull the two sides of the placement plate 13, so that the placement plate 13 performs reciprocating vertical displacement, thereby causing the placement plate 13 to vibrate, thereby avoiding the raw materials on the placement plate 13 from adhering to the placement plate 13, which is not only convenient for the staff to take out and clean the materials after the calcination is completed, but also enables the anode carbon blocks on the placement plate 13 to be uniformly calcined, thereby improving the production quality of the anode carbon blocks. Slide grooves 331 are provided on the two side walls of the device body 1, and the two fixed rods 33 extend to the interior of the placement cavity 12 through the two slide grooves 331 respectively, and are fixedly connected to the two sides of the placement plate 13, and the two fixed rods 33 are slidably connected to the inner walls of the two slide grooves 331 respectively, which limit the two reciprocating threaded sleeves 32, so that the two reciprocating threaded sleeves 32 always perform vertical displacement to prevent them from rotating.

[0038] A second transmission assembly 5 is also provided inside the device body 1, and the rotating rod 22 is controlled by the motor 14 through the second transmission assembly 5. The second transmission assembly 5 includes a third gear 51, a fourth gear 52 and a rotating shaft 53. The rotating shaft 53 is rotatably connected to the bottom wall of the device body 1 below the first transmission assembly 4. The output shaft of the motor 14 is fixedly connected to the rotating shaft 53. The third gear 51 is interference fit at the top of the rotating shaft 53. The rotating rod 22 and the third gear 51 are interference fit at a position on the same horizontal line with the fourth gear 52, and the third gear 51 and the fourth gear 52 are meshed with each other.

[0039] It should be noted that since the roasting component 2 and the two vibration components 3 in the device body 1 are all driven by the rotating rod 22, it is easy to cause a huge load on the motor 14. The third gear 51 in the second transmission component 5, which is fixed to the output shaft of the motor 14, has a radius of only one-fourth of the radius of the fourth gear 52 fixed to the rotating rod 22. When the third gear 51 rotates sixteen times, the rotating rod 22 only rotates one circle, which greatly reduces the load on the motor 14 and extends the service life of the motor 14.

[0040] The present invention can be explained by the following operation mode:

[0041] S1: When in use, the device body 1 is fixed inside the roasting furnace, raw materials are transported into the device body 1, and the motor 14 and the two burners 26 are turned on.

[0042] S2: The motor 14 will drive the rotating shaft 53 to rotate, and drive the rotating rod 22 to rotate through the third gear 51 and the fourth gear 52, which greatly reduces the load of the motor 14. When the rotating rod 22 rotates, it will drive the first gear 23 to rotate, so that a burner 26 on the first gear 23 performs a circular motion. When the first gear 23 rotates, the second gear 24 performs a circular motion around the first gear 23, so that another burner 26 on the second gear 24 performs a circular motion, thereby uniformly calcining the raw materials on the placement plate 13, greatly improving the calcination performance of the roasting furnace.

[0043] S3: When the rotating rod 22 rotates, the two reciprocating threaded rods 31 will be driven to rotate through the three transmission wheels 41 and the transmission belt 42, so that the two reciprocating threaded sleeves 32 will reciprocate vertically, and the placement plate 13 will be driven to reciprocate vertically through the two fixed rods 33 to generate vibration, thereby preventing the raw materials on the placement plate 13 from sticking to the placement plate 13, which not only facilitates material removal and cleaning, but also improves the production quality of anode carbon blocks.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
