Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, specifically relating to a mixed feeding device for metallurgical mines. Background Technology

[0002] In the material conveying and mixing process in industries such as metallurgy, mining, and building materials, mineral powders, furnace materials, additives, etc. of different particle sizes, specific gravities, or types must be mixed evenly in proportion before entering the subsequent sintering, smelting, or granulation processes.

[0003] Chinese utility model patent CN222389136U discloses a metallurgical mining mixing and feeding device. It "transfers materials stored in two storage bins to a mixing bin via two material conveyor belts. The materials are mixed in the mixing bin and then sent out by the mixed material conveyor belt. This device optimizes and integrates the mixing and feeding processes, which effectively solves the problem of difficult mixing and feeding in the metallurgical mining production environment and improves production efficiency." However, it lacks the function of adjusting the conveying rate of the two materials, and the discharge rhythm is uncontrollable. Therefore, it is impossible to ensure that the two materials are uniformly mixed in proportion during the conveying process. It is easy for one material to be conveyed completely while the other material still needs to be conveyed for a long time. The remaining material cannot be mixed with the other material synchronously during the conveying process. In addition, the mixing bin is only equipped with immovable mixing tooth blocks, which has a limited effect on the mixing of materials. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a metallurgical mining mixing and feeding device that can adjust the ratio of the output speed of the first and second storage bins as needed to meet the feeding and mixing requirements of different materials, improve the uniformity of material mixing, completely eliminate the need for subsequent mixing steps, and significantly improve production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metallurgical mining mixing and feeding device, comprising a first storage bin and a second storage bin, the bottoms of which are connected to a feeding mechanism. The feeding mechanism includes a feeding cylinder installed below the first and second storage bins. A feeding roller is rotatably mounted on the inner side of the feeding cylinder, and multiple feeding grooves are arranged in a ring on the outer side of the feeding roller. One end of the feeding roller is connected to a connecting shaft, and one end of the connecting shaft is provided with a slot. The slot is inserted and connected to a replaceable pulley. The bottom of the feeding cylinder is connected to a transfer channel. A motor mounting bracket is installed on the side of the transfer channel. A first motor is installed on one side of the motor mounting bracket. The output end of the first motor is connected to a first pulley, and one end of the first pulley is connected to a second pulley. The bottom of the transfer channel is connected to a mixing enhancement device, and a conveyor belt is provided below the mixing enhancement device.

[0006] The beneficial effects of this utility model are as follows: The bottom of the first and second storage bins is equipped with a feeding mechanism. A feeding roller is rotatably mounted inside the feeding cylinder of this mechanism. Multiple annular feeding grooves are evenly distributed on the surface of the roller, enabling it to feed materials out in batches during rotation. When the device is running, the output of the first motor drives the first pulley and the second pulley to rotate. The first and second pulleys drive a replaceable pulley to rotate via a belt, thereby driving the feeding roller to rotate, achieving controllable discharge rhythm. The feeding roller is connected to the replaceable pulley via a connecting shaft at one end. One end of the connecting shaft has a slot, which is fixed to the insert block on the back of the replaceable pulley by a locking bolt. Replaceable pulleys of different diameters can be flexibly replaced according to different speed requirements to adjust the feeding speed of the feeding mechanism at the bottom of the first and second storage bins. The speed ratio of the feeding rollers in the two feeding mechanisms is determined by the ratio between the circumferences of the replaceable pulleys connected to the two feeding mechanisms, thereby determining the ratio of the speed at which the first and second storage bins output material, meeting the feeding ratio requirements of different materials.

[0007] Material in the transfer channel falls into the enhanced mixing chamber for further mixing. A second motor drives the first rotating shaft to rotate, and a bevel gear meshes between the first and second rotating shafts. The first rotating shaft drives the second rotating shaft to rotate, and a paddle mounted on top of the second rotating shaft rotates and agitates the material, causing it to move back and forth in the enhanced mixing chamber, enhancing the agitation and fusion of the material inside. An umbrella-shaped plate is set above the paddle to effectively guide the falling material to disperse evenly. At the same time, multiple falling delay plates are set on the inner wall of the mixing chamber. Some of the material agitated by the paddle can move to the top of the falling delay plates and then slide down the inclined surface of the falling delay plates, slowing down the falling speed of the material due to gravity, extending the mixing time, and improving the uniformity of material mixing. The further mixing of the material is completed on the way to the conveyor belt, eliminating the need for subsequent mixing steps and significantly improving production efficiency.

[0008] As a further improvement to the above technical solution: threaded holes are provided between the outer side of the connecting shaft and the slot, and between the two sides of the part of the replaceable pulley inserted into the slot, and the connection is made by locking bolts.

[0009] For storage of replaceable pulleys and belts:

[0010] As a further improvement to the above technical solution: a pulley storage box is provided on the side of the transfer channel.

[0011] The beneficial effects of this improvement are: the pulley storage box is used to store replaceable pulleys of different circumferences and matching belts.

[0012] To prevent material from splashing:

[0013] As a further improvement to the above technical solution, a splash guard is provided on the top of the conveyor belt.

[0014] The beneficial effect of this improvement is that a splash guard is installed on the top of the conveyor belt to prevent material from splashing.

[0015] As a further improvement to the above technical solution: the first pulley and the replaceable pulley, and the second pulley and the replaceable pulley are both connected by belts.

[0016] The first and second pulleys drive the replaceable pulleys to rotate.

[0017] In order to mix the materials:

[0018] As a further improvement to the above technical solution: the enhanced mixing device includes an enhanced mixing chamber, a hollow cantilever is installed on the inner side of the enhanced mixing chamber, a second motor is installed at one end of the hollow cantilever, a first rotating shaft and a second rotating shaft are rotatably installed on the inner side of the hollow cantilever, bevel gears are fixedly installed on the outer side of the first rotating shaft and the bottom of the second rotating shaft, a paddle is connected to the top of the second rotating shaft, and an umbrella-shaped plate and a falling delay plate are installed on the inner side of the enhanced mixing chamber.

[0019] The beneficial effects of this improvement are as follows: the material in the transfer channel falls into the enhanced mixing chamber for further mixing. The first rotating shaft is driven to rotate by the second motor. The first and second rotating shafts are meshed and transmitted through bevel gears. The first rotating shaft drives the second rotating shaft to rotate. A paddle is installed on the top of the second rotating shaft, which rotates and stirs continuously, patting the material and causing it to move back and forth in the enhanced mixing chamber, thus enhancing the disturbance and fusion of the material inside the mixing chamber. An umbrella-shaped plate is set above the paddle to effectively guide the falling material to be evenly dispersed. At the same time, multiple falling delay plates are set on the inner wall of the mixing chamber. Some of the material patted by the paddle can move to the top of the falling delay plates and then slide down along the inclined surface of the falling delay plates, slowing down the falling speed of the material due to gravity, extending the mixing time, and improving the uniformity of material mixing.

[0020] As a further improvement to the above technical solution: the umbrella-shaped plate is located above the paddle, and multiple descent delay ring plates are provided.

[0021] To drive the paddle to rotate:

[0022] As a further improvement to the above technical solution: the bevel gear on the first rotating shaft meshes with the bevel gear on the second rotating shaft.

[0023] The beneficial effects of this improvement are: when the first rotating shaft is driven to rotate by the second motor, the second rotating shaft is driven to rotate synchronously through the bevel gear transmission, thereby driving the paddle to rotate.

The bottoms of both the first storage bin 1 and the second storage bin 2 are connected to a feeding mechanism 3. The feeding mechanism 3 includes a feeding cylinder 4 installed below the first storage bin 1 and the second storage bin 2. A feeding roller 5 is rotatably installed on the inner side of the feeding cylinder 4. A plurality of feeding grooves 6 are arranged in a ring on the outer side of the feeding roller 5. One end of the feeding roller 5 is connected to a connecting shaft 7. One end of the connecting shaft 7 is provided with a slot 8. The slot 8 is inserted and connected to a replaceable pulley 9. The bottom of the feeding cylinder 4 is connected to a transfer channel 17. A motor mounting bracket 11 is installed on the side of the transfer channel 17. A first motor 12 is installed on one side of the motor mounting bracket 11. The output end of the first motor 12 is connected to a first pulley 13. One end of the first pulley 13 is connected to a second pulley 14. The bottom of the transfer channel 17 is connected to a mixing enhancement device. A conveyor belt 27 is provided below the mixing enhancement device.

[0034] The bottom of the first storage bin 1 and the second storage bin 2 are equipped with a feeding mechanism 3. A feeding roller 5 is rotatably mounted inside the feeding cylinder 4 of this mechanism. Multiple annular feeding grooves 6 are evenly distributed on the surface of the roller, enabling it to feed materials out in batches during rotation. When the device is running, the output end of the first motor 12 drives the first pulley 13 and the second pulley 14 to rotate. The first pulley 13 and the second pulley 14 drive the replaceable pulley 9 to rotate via a belt 15, thereby driving the feeding roller 5 to rotate, achieving controllable material discharge rhythm. The feeding roller 5 is connected to the replaceable pulley 9 via a connecting shaft 7 at one end. The connection shaft 7 has a slot 8 at one end, which is fixed to the insert on the back of the replaceable pulley 9 by a locking bolt 10. The replaceable pulley 9 of different diameters can be flexibly replaced according to different speed requirements to adjust the feeding speed of the feeding mechanism 3 at the bottom of the first storage box 1 and the second storage box 2. The speed ratio of the feeding roller 5 in the two feeding mechanisms 3 is determined by the ratio between the circumferences of the replaceable pulleys 9 connected by the two feeding mechanisms 3, thereby determining the ratio of the speed at which the first storage box 1 and the second storage box 2 output materials, so as to meet the feeding ratio requirements of different materials.

[0035] The material in the transfer channel 17 falls into the enhanced mixing chamber 18 for further mixing. The first rotating shaft 21 is driven to rotate by the second motor 20. The first rotating shaft 21 and the second rotating shaft 22 are meshed and transmitted through the bevel gear 23. The first rotating shaft 21 drives the second rotating shaft 22 to rotate. The top of the second rotating shaft 22 is equipped with a stirring paddle 24, which rotates and stirs continuously, patting the material and making it move back and forth in the enhanced mixing chamber 18, enhancing the disturbance and fusion of the material inside the mixing chamber. An umbrella-shaped plate 25 is set above the stirring paddle to effectively guide the falling material to be evenly dispersed. At the same time, multiple falling delay ring plates 26 are set on the inner wall of the mixing chamber. Some of the material patted by the stirring paddle 24 can move to the top of the falling delay ring plates 26 and then slide down along the inclined surface of the falling delay ring plates 26, slowing down the falling speed of the material due to gravity, extending the mixing time, and improving the mixing uniformity of the material. The further mixing of the material is completed on the way to the conveyor belt, without the need for subsequent mixing steps, which significantly improves production efficiency.

[0036] The outer side of the connecting shaft 7 and the slot 8, as well as the two sides of the part of the replaceable pulley 9 inserted into the slot 8, are provided with threaded holes and connected by locking bolts 10.

[0040] The top of the conveyor belt 27 is equipped with a splash guard 28 to prevent material from splashing.

[0041] The first pulley 13 and the replaceable pulley 9, and the second pulley 14 and the replaceable pulley 9 are both connected by belts 15.

[0042] The enhanced mixing device includes an enhanced mixing chamber 18, a hollow cantilever 19 is installed on the inner side of the enhanced mixing chamber 18, a second motor 20 is installed at one end of the hollow cantilever 19, a first rotating shaft 21 and a second rotating shaft 22 are rotatably installed on the inner side of the hollow cantilever 19, bevel gears 23 are fixedly installed on the outer side of the first rotating shaft 21 and the bottom of the second rotating shaft 22, a paddle 24 is connected to the top of the second rotating shaft 22, and an umbrella-shaped plate 25 and a falling delay plate 26 are installed on the inner side of the enhanced mixing chamber 18.

[0043] The material in the transfer channel 17 falls into the enhanced mixing chamber 18 for further mixing. The first rotating shaft 21 is driven to rotate by the second motor 20. The first rotating shaft 21 and the second rotating shaft 22 are meshed and transmitted through the bevel gear 23. The first rotating shaft 21 drives the second rotating shaft 22 to rotate. The top of the second rotating shaft 22 is equipped with a stirring paddle 24, which rotates and stirs continuously, patting the material and making it move back and forth in the enhanced mixing chamber 18, enhancing the disturbance and fusion of the material inside the mixing chamber. An umbrella-shaped plate 25 is set above the stirring paddle to effectively guide the falling material to be evenly dispersed. At the same time, multiple falling delay ring plates 26 are set on the inner wall of the mixing chamber. Some of the material patted by the stirring paddle 24 can move to the top of the falling delay ring plate 26 and then slide down along the inclined surface of the falling delay ring plate 26, slowing down the falling speed of the material due to gravity, prolonging the mixing time, and improving the uniformity of the material mixing.

[0046] When the first rotating shaft 21 is driven to rotate by the second motor 20, it drives the second rotating shaft 22 to rotate synchronously through the bevel gear 23, thereby driving the paddle 24 to rotate.

[0047] The working principle and usage process of this utility model are as follows: When using this metallurgical mining mixed feeding device, different types of materials are respectively loaded into the first storage box 1 and the second storage box 2. The bottom of the first storage box 1 and the second storage box 2 are provided with a feeding mechanism 3. A feeding roller 5 is rotatably installed inside the feeding cylinder 4 of this mechanism. Multiple annular feeding grooves 6 are evenly distributed on the surface of the roller, which can feed out the material in batches during rotation, so as to achieve controllable discharge rhythm. The feeding roller 5 is connected to a replaceable pulley 9 through a connecting shaft 7 at one end. One end of the connecting shaft 7 is provided with a slot 8, which is fixed to the insert on the back of the replaceable pulley 9 by a locking bolt 10, and can be adjusted according to... The replaceable pulleys 9 of different diameters can be flexibly replaced according to different speed requirements to adjust the feeding speed of the feeding mechanism 3 at the bottom of the first storage bin 1 and the second storage bin 2. The speed ratio of the feeding rollers 5 in the two feeding mechanisms 3 is determined by the ratio between the circumferences of the replaceable pulleys 9 connected to the two feeding mechanisms 3, thereby determining the ratio of the output speed of the material from the first storage bin 1 and the second storage bin 2 to meet the feeding ratio requirements of different materials. When the device is running, the output end of the first motor 12 drives the first pulley 13 and the second pulley 14 to rotate. The first pulley 13 and the second pulley 14 drive the replaceable pulleys 9 at the bottom of the first storage bin 1 and the second storage bin 2 through the belt 15. The rotation of pulley 9 drives the material feeding roller 5, establishing a stable power transmission system. The bottom of the feeding cylinder 4 is connected to the transfer channel 17. Different materials are fed out from the feeding groove 6 and fall into the transfer channel 17 to converge. At the same time, the side of the transfer channel 17 is equipped with a pulley storage box 16 for storing replaceable pulleys 9 of different circumferences and matching belts 15. The bottom of the transfer channel 17 is connected to the enhanced mixing device. The materials in the transfer channel 17 fall into the enhanced mixing chamber 18 for further mixing. The first rotating shaft 21 is driven to rotate by the second motor 20. The first rotating shaft 21 and the second rotating shaft 22 are connected by a bevel gear 23. The meshing transmission drives the second shaft 22 to rotate via the first shaft 21. The top of the second shaft 22 is equipped with a paddle 24, which rotates and stirs continuously, patting the material and causing it to move back and forth in the mixing chamber 18, thus enhancing the agitation and fusion of the material inside the mixing chamber. An umbrella-shaped plate 25 is set above the paddle to effectively guide the falling material to disperse evenly. At the same time, multiple falling delay ring plates 26 are set on the inner wall of the mixing chamber. Some of the material patted by the paddle 24 can move to the top of the falling delay ring plates 26 and then slide down along the inclined surface of the falling delay ring plates 26, slowing down the falling speed of the material due to gravity, extending the mixing time, and improving the uniformity of material mixing.The final mixed material is discharged from the bottom and falls onto the conveyor belt 27 below. The top of the conveyor belt 27 is equipped with a splash guard 28 to prevent material from splashing. The material is then transported to the production line via the conveyor belt 27. In summary, this device can adjust the supply rate of different materials according to the mixing ratio, meeting the need for simultaneous feeding of different materials. This ensures that different materials are evenly distributed throughout the overall material, and further mixing is completed during the feeding process onto the conveyor belt, eliminating the need for subsequent mixing steps and significantly improving production efficiency.
