Description

Technical Field

[0001] This utility model belongs to the technical field of carbon block packing, and particularly relates to a carbon block packing structure for a roasting furnace. Background Technology

[0002] The operation of the carbon block filler in the roasting furnace is a crucial step in the carbon block roasting process. During filler preparation, suitable materials such as metallurgical coke, river sand, petroleum coke, or anthracite are selected based on the roasting process requirements. These fillers can be used individually or in combination. After selection, the filler is processed, such as crushing and screening, to meet specific particle size requirements. Charging involves filling the processed filler into the carbon block hopper, which is the carbon block filler operation in the roasting furnace. Currently, the main problem in this operation is the poor accuracy of the filler, requiring multiple leveling processes to ensure uniform distribution of the filler around each carbon block. Summary of the Invention

[0003] In order to overcome the technical problems described in the background, this utility model provides a charcoal block packing structure for a roasting furnace, which can improve the accuracy of packing and reduce the number of leveling operations. Multiple vertical cylinders are set below the material box, and packing balls are set below the vertical cylinders. One rotation of the packing ball is one packing operation. The amount of packing in a certain area of ​​the roasting furnace depends on the number of rotations of the packing ball.

[0004] The technical solution of this utility model is as follows: a charcoal block packing structure for a roasting furnace, including a material box, vertical cylinders, an electric drive component, a belt drive component, packing balls, a spherical shell constraint component, a side rotating shaft, and a central rotating shaft. The bottom of the material box is provided with multiple vertical cylinders arranged sequentially from left to right. The bottom of each vertical cylinder is provided with a spherical shell constraint component, and a packing ball is provided inside the spherical shell constraint component. Each packing ball has a material receiving cavity for accommodating materials. The opening of the material receiving cavity can, as the packing ball rotates, connect upwards to the vertical cylinders to receive material filling and downwards to discharge material to the charcoal blocks below. A central rotating shaft is provided between the packing balls. A side rotating shaft is provided on the outermost packing ball, away from the other packing balls. The axis of the side rotating shaft, the center of the packing ball, and the axis of the central rotating shaft are on the same straight line. An electric drive component is provided on the side wall of the material box, and an upper drive shaft is provided on the electric drive component to transmit power. A belt drive component is provided between the end of the upper drive shaft and the end of the side rotating shaft.

[0005] Furthermore, the upper end of the packing ball is provided with an upward-opening material receiving cavity, and the left and right ends are respectively provided with shaft embedding holes for embedding the intermediate shaft or the side shaft. The part of the packing ball on the front and rear sides of the shaft embedding hole is provided with a side insertion hole. The side insertion hole is provided with a pin hole that connects to the corresponding shaft embedding hole, so that the embedded intermediate shaft or side shaft can be pin-connected with the packing ball. The pin is inserted from the side insertion hole and passes through the end of the intermediate shaft or the side shaft.

[0006] Furthermore, the spherical shell constraint component includes an upper buckle shell and a lower support shell.

[0009] The beneficial effects of this utility model due to the adoption of the above-mentioned technology are as follows.

[0010] 1. This utility model can improve the accuracy of filling and reduce the number of leveling operations. Multiple vertical cylinders are set below the material box, and filling balls are set below the vertical cylinders. One rotation of the filling ball is one filling operation.

The four corners of the support frame 2 are suspended from the hooks of a gantry crane by steel cables. The material box 1 is arranged above the roasting furnace via the support frame 2, directly above the charcoal blocks 8. The bottom of the material box 1 has multiple vertical cylinders 13 arranged sequentially from left to right. The bottom of the vertical cylinders 13 has a spherical shell constraint component, and the spherical shell constraint component contains packing spheres 17. The packing spheres 17 have a material receiving cavity 18 for accommodating materials. The opening of the material receiving chamber 18 can connect upward to the vertical cylinder 13 to receive material filling and downward to discharge material to the carbon blocks 8 below as the packing balls 17 rotate. An intermediate rotating shaft 16 is provided between the packing balls 17. A side rotating shaft 15 is provided on the part of the outermost packing ball 17 away from the other packing balls 17. The axis of the side rotating shaft 15, the center of the packing ball 17 and the axis of the intermediate rotating shaft 16 are on the same straight line. An electric drive component is provided on the side wall of the material box 1. An upper drive shaft 14 is provided on the electric drive component to transmit power. A belt drive component is provided between the end of the upper drive shaft 14 and the side rotating shaft 15.

[0022] In this way, during use, the electric drive component drives the side rotating shaft 15 to rotate through the upper drive shaft 14 and the belt drive component. The side rotating shaft 15 drives the packing ball 17 to rotate back and forth. The material receiving cavity 18 on the packing ball 17 quantitatively fills the material in the vertical cylinder 13 into the carbon bowl of the carbon block 8 below. One rotation of the packing ball 17 is one filling operation. The amount of packing in a region of the roasting furnace depends on the number of rotations of the packing ball 17.

[0023] The packing ball 17 has an upward-opening material cavity 18 at its upper end and shaft insertion holes 20 at its left and right ends for embedding the intermediate shaft 16 or the side shaft 15.

The upper buckle shell 12 is fastened to the lower support shell 7 and its upper opening is fixed to the vertical cylinder 13 and communicates with the vertical cylinder 13. The lower end of the lower support shell 7 is provided with a notch that exposes the packing ball 17 downwards.

The driven pulley 9 and the driving pulley 11 are respectively mounted on the side rotating shaft 15 and the upper drive shaft 14, and the drive belt 10 is provided between them to form a belt drive. Note that the drive belt 10 is made of a material that has a large friction with the driven pulley 9 and the driving pulley 11, or it is made of a V-shaped drive belt 10 to ensure that the drive belt 10 does not slip as much as possible. Of course, a chain drive can also be used, in which case the driven pulley 9, the driving pulley 11, and the drive belt 10 are replaced by a driven chain, a driving chain, and a drive chain, respectively.

[0026] The electric drive component includes a motor 4, a reducer 5, and a transmission gear 6. The motor 4 is connected to a microcontroller in a microcontroller control box on the inclined box wall 3 via a wire. The motor 4 and the reducer 5 are connected in sequence and respectively bolted to the inclined box wall 3 at the lower end of the material box 1. The output shaft of the reducer 5 is equipped with a transmission gear 6, which meshes with the driven gear in the center of the upper transmission shaft 14, so that the motor 4 drives the upper transmission shaft 14 to rotate in sequence through the reducer 5, the transmission gear 6, and the driven gear.

[0027] The microcontroller control box is bolted to the inclined box wall 3. Inside the microcontroller control box is a microcontroller control board as the control unit, a 4G communication module as the communication unit, and a lithium battery as the backup power supply unit. The power supply line of motor 4 is connected from the overhead crane. The microcontroller control board is electrically connected to motor 4, 4G communication module and lithium battery in sequence. The plant control center can realize the Internet of Things in the plant through the server and multiple microcontroller control boxes. It can send control commands to start and stop motor 4 to the microcontroller control board through the 4G communication module.

[0028] Example 2: Based on Example 1, in order to further improve the accuracy of filling, a speed sensor capable of detecting the rotation speed of the side shaft 15 is provided on the upper casing 12. The speed sensor is connected to the microcontroller in the microcontroller control box on the inclined box wall 3 through wires, and can transmit the signal detected by the speed sensor to the plant control center to facilitate the digital management of the plant.
