Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, and in particular to a raw material mixing and processing equipment and method for ferromolybdenum production. Background Art

[0002] The production process of ferromolybdenum is divided into two steps: one is the roasting of molybdenum concentrate; the other is the smelting of ferromolybdenum alloy. The roasting production process is to put molybdenum concentrate into an internal combustion rotary kiln, and use the heat generated by igniting coal to oxidize the molybdenum concentrate in the kiln to generate heat, thereby completing the oxidation reaction in the kiln. The generated molybdenum oxide is transported to the molybdenum oxide warehouse by a closed chain plate, and is broken by a hammer crusher and reserved. The smelting of ferromolybdenum alloy mainly uses the aluminothermic reduction method for smelting. The raw materials mainly include industrial molybdenum oxide, ferrosilicon powder, aluminum powder, sodium nitrate, iron ore powder, steel chips, heating agent and oxide powder. The raw materials need to be mixed to form furnace charge. When smelting in a smelting furnace, the charging is carried out in batches. Since aluminum powder cannot be stacked together with the heating agent and oxide powder in the raw materials, this makes it impossible to store the furnace charge. The furnace charge must be immediately melted after being mixed and cannot be stored. Since the furnace charge needs to be put in batches, the raw materials can only be mixed before being put in, resulting in a long idle period in the smelting process and significantly reducing the smelting efficiency. In addition, each time of feeding requires transporting the furnace charge to the feed inlet at the top of the smelting furnace, which further reduces the smelting efficiency. Therefore, a raw material mixing and processing equipment and method for ferromolybdenum production are proposed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art that the raw materials can only be mixed before being put in, resulting in a long idle period in the smelting process and significantly reducing the smelting efficiency. In addition, each time of feeding requires transporting the furnace charge to the feed inlet at the top of the smelting furnace, which further reduces the smelting efficiency, and to propose a raw material mixing and processing equipment and method for ferromolybdenum production.

A blanking port communicating with the blanking nozzle is opened at the bottom end of the mobile housing. A lower opening is opened on the side wall of the mobile housing. A lower opening plate is slidably connected to the inner wall of the blanking port. One end of the lower opening plate is connected to the side wall of the mobile housing through a lower return spring.

A mixing motor connected to one of the rotating shafts is installed on the outer side wall of the feeding nozzle.

[0012] A processing method proposed for a raw material mixing and processing device for ferromolybdenum production includes the following steps:

[0013] S1. Preliminary mixing of raw materials: Place the raw materials in batches on the corresponding backing plates, accurately weigh the raw materials using an electronic scale, and then, under the action of the material conveying frame, achieve the function of separating the iron powder from other raw materials and the function of conveying the raw materials. During the conveying process, pre-mix other raw materials using the mixing comb plates inside the material conveying frame, and at the same time achieve the drying function of the iron powder.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, refer to Figures 1 to 8 , a raw material mixing and processing device for ferromolybdenum production, including a vibrating bottom plate 19 arranged on the ground through a support plate and a conveyor belt 1 connected to the side wall of the support plate through a V-shaped frame (both the conveyor belt 1 and the support plate are provided with two and are symmetrically arranged, and the conveyor belt 1 is arranged to rotate intermittently). At one end near the bottom of the vibrating bottom plate 19 (the initial conveying end of the conveyor belt 1), an L-shaped mounting plate is fixedly connected. A plurality of electronic scales 13 are installed on the L-shaped mounting plate, and a cushion plate 21 flush with the vibrating bottom plate 19 is arranged at the top of the electronic scales 13;

[0034] It should be noted that: the electronic scales 13 are used to weigh various raw materials separately to facilitate the proportioning of raw materials.

[0035] It should be noted that: the L-shaped mounting plate is used to install the electronic scales 13, and the cushion plate 21 is arranged flush with the vibrating bottom plate 19, which can ensure that the material conveying frame 3 pushes the raw materials flat onto the vibrating bottom plate 19 to facilitate the conveying of raw materials.

[0036] A plurality of vibrating slide rails 12 are uniformly arranged on the surface of the conveyor belt 1. A connecting slider 16 is slidably arranged inside the vibrating slide rails 12. One end of the connecting slider 16 is fixedly connected with a material conveying frame 3, and the material conveying frame 3 is connected to the inner wall of the vibrating slide rails 12 through a resisting spring 17;

[0037] It should be noted that: the resisting spring 17 is in a compressed state. Cooperating with the connecting slider 16, the bottom end of the material conveying frame 3 is tightly attached to the vibrating bottom plate 19, ensuring that during the movement of the material conveying frame 3, the function of conveying raw materials can be realized. At the same time, during the vibration of the vibrating bottom plate 19, the material conveying frame 3 vibrates synchronously with the vibrating bottom plate 19 under the elastic force of the resisting spring 17, ensuring that during the vibration process, the bottom end of the material conveying frame 3 is always in close contact with the vibrating bottom plate 19, avoiding the phenomenon of raw material leakage.

[0038] Inside the feeding frame 3, there are a circular material trough and a square material trough. A mixing comb plate 14 is slidably arranged inside the square material trough. Inside the feeding frame 3, an electromagnetic induction coil 15 is arranged around the circular material trough. On both sides of the conveyor belt 1, a plurality of traction alternating magnets 4 connected to the support plate and repulsion alternating magnets 34 are alternately arranged. The tops of the traction alternating magnets 4 and the repulsion alternating magnets 34 are fixedly connected to an elastic sealing plate 2 together.

[0039] It should be noted that: the alternating order of the traction alternating magnets 4 (the magnets for magnetically attracting the mixing comb plate 14) and the repulsion alternating magnets 34 (the magnets for magnetically repelling the mixing comb plate 14) on both sides of the conveyor belt 1 is opposite. That is, the arrangement order of the traction alternating magnets 4 and the repulsion alternating magnets 34 on the left side of the conveyor belt 1 is that the traction alternating magnet 4 and the repulsion alternating magnet 34 appear alternately, and the appearance order of the two on the right side of the conveyor belt 1 is that the repulsion alternating magnet 34 and the traction alternating magnet 4 appear alternately.

[0040] It should be noted that: the circular material trough is used to place iron powder. Since the iron powder needs to be dried before mixing, the square material trough is used to place other raw materials except iron powder. During the conveying process, the mixing comb plate 14 moves back and forth left and right, which can pre-mix other raw materials, facilitating the final mixing of subsequent raw materials and reducing the time for the final mixing of subsequent raw materials.

[0041] At the conveying end of the conveyor belt 1, there is a pair of mobile vehicles 10 (the mobile vehicles 10 are electric vehicles and can be driven by an external controller). The top of the mobile vehicle 10 is fixedly connected to a lifting electric control slide rail 5 through a vertical plate. Inside the lifting electric control slide rail 5, a translation electric control slide rail 8 is slidably connected through a lifting slide seat. Inside the translation electric control slide rail 8, a translation slide seat is slidably arranged.

[0042] It should be noted that: both the lifting electric control slide rail 5 and the translation electric control slide rail 8 are prior arts, and their specific structures and working principles will not be elaborated here.

[0043] It should be noted that: the lifting electric control slide rail 5 and the translation electric control slide rail 8 cooperate with the mobile vehicle 10, which can realize the functions of raising and translating the aluminum material conveying part, and can convey all batches of raw materials to the feeding port at the top of the smelting furnace at one time, realizing the feeding function of the raw materials.

[0044] One end of the translation slider is fixedly connected to a moving housing 7. A separating hopper 6 is fixedly connected to the top end of the moving housing 7. A blanking partition plate 22 is fixedly connected inside the separating hopper 6 (the blanking partition plate 22 can separate iron powder and other raw materials to prevent them from being mixed when entering the inside of the conveying groove. At this time, the iron powder has just been heated and dried and has a relatively high temperature, and it needs to be cooled before being mixed with other raw materials). A blanking nozzle 11 is fixedly connected to the bottom end of the moving housing 7. A furnace charge conveying member 23 is rotatably arranged inside the moving housing 7. A conveying groove is arranged on the inner circumference of the furnace charge conveying member 23 (the number of conveying grooves is the same as the number of batches of raw materials, which is convenient for storing each batch of raw materials separately). A conveying partition plate 24 is fixedly connected inside the conveying groove (the conveying partition plate 24 prevents the iron powder from being mixed with other raw materials inside the conveying groove and gives the iron powder enough cooling time). A transfer groove is opened at the center of the furnace charge conveying member 23, and an internal mixing cylinder 27 is rotatably connected inside the transfer groove.

[0045] Further, a mixing blanking port 1902 adapted to the square material groove and an iron powder blanking port 1901 adapted to the circular material groove are opened inside the vibration bottom plate 19 near the conveying end of the conveyor belt 1. A vibration motor 20 for driving the vibration of the vibration bottom plate 19 is installed at the bottom end of the vibration bottom plate 19.

[0046] It should be noted that: the setting of the mixing blanking port 1902 facilitates the pre-mixed raw materials in the square material groove inside the material conveying frame 3 to enter the inside of the separating hopper 6. The setting of the iron powder blanking port 1901 facilitates the dried iron powder inside the circular material groove to enter the inside of the separating hopper 6.

[0047] Further, an intermittent motor 18 is installed on the outer side of the moving housing 7. The output shaft of the intermittent motor 18 penetrates the moving housing 7 and is fixedly connected to the furnace charge conveying member 23 (the intermittent motor 18 drives the furnace charge conveying member 23 to rotate intermittently).

[0048] A blanking port communicating with the blanking nozzle 11 is opened at the bottom end of the moving housing 7. A lower opening is opened on the side wall of the moving housing 7. A lower opening plate 31 is slidably connected to the inner wall of the blanking port. One end of the lower opening plate 31 is connected to the side wall of the moving housing 7 through a lower return spring 32. Further, a lower opening electromagnet 35 that is mutually magnetically repulsive to the lower opening plate 31 is installed on the other side of the moving housing 7 facing the lower opening plate 31. An outlet interface is opened at the bottom end of the internal mixing cylinder 27. An upper opening aligned with the outlet interface is opened on the side wall of the moving housing 7. An upper opening plate 30 is slidably connected to the inner wall of the outlet interface. One end of the upper opening plate 30 is fixedly connected to one side of the moving housing 7 through an upper return spring. An upper opening electromagnet 25 that is mutually magnetically repulsive to the upper opening plate 30 is installed on the other side of the moving housing 7 facing the upper opening plate 30.

[0049] It should be noted that when the raw materials inside the conveying trough need to be poured into the smelting furnace, the conveying trough is rotated to the material discharge nozzle 11, and then the upper opening and closing electromagnet 25 is first turned on. By using the magnetic repulsion force between the upper opening and closing electromagnet 25 and the upper opening and closing plate 30, the upper opening and closing plate 30 is pushed to move, so that the discharge interface at the bottom of the built-in mixing cylinder 27 is opened. The heating agent and oxide powder inside the built-in mixing cylinder 27 enter the inside of the conveying trough through the discharge interface and the feed interface at the bottom of the conveying trough and come into contact with the pre-mixed raw materials inside the conveying trough;

[0050] After that, the lower opening and closing electromagnet 35 is turned on. By using the magnetic repulsion force between the lower opening and closing electromagnet 35 and the lower opening and closing plate 31, the lower opening and closing plate 31 is pushed to move, so that the material discharge port at the bottom of the moving housing 7 is opened, and all the raw materials inside the conveying trough enter the inside of the material discharge nozzle 11.

[0051] Furthermore, a feed interface is provided at the bottom of the conveying trough. A turning motor 28 is installed on the side wall of the moving housing 7. The output shaft of the turning motor 28 extends into the inside of the built-in mixing cylinder 27 and is fixedly connected to a main shaft. A plurality of turning plates 29 are fixedly connected to the surface of the main shaft.

[0052] It should be noted that a hinged door is provided on the side wall of the moving housing 7 at the position of the built-in mixing cylinder 27 for pouring the heating agent and oxide powder into the inside of the built-in mixing cylinder 27;

[0053] The turning motor 28 drives the main shaft to rotate, and then drives the turning plates 29 to rotate, so as to mix the heating agent and oxide powder.

[0054] Furthermore, relatively arranged rotating shafts are rotatably connected inside the material discharge nozzle 11. The surface of the rotating shafts is fixedly connected with material discharge mixing plates 9. One ends of the two material discharge mixing plates 9 are fixedly connected with meshing gears 33 that mesh with each other. A mixing motor 26 connected to one of the rotating shafts is installed on the outer side wall of the material discharge nozzle 11.

[0055] It should be noted that the mixing motor 26 drives the rotating shafts to rotate, and then drives the material discharge mixing plates 9 to rotate, so as to finally mix the raw materials entering the material discharge nozzle 11. The formed furnace charge enters the smelting furnace, realizing the function of synchronously carrying out raw material discharging and mixing, and eliminating the blank period during the smelting process.

[0056] Please refer to Figure 9 , a processing method proposed for a raw material mixing and processing device for ferromolybdenum production, including the following steps:

[0057] S1. Pre - mixing of raw materials: Place the raw materials in batches on the corresponding backing plates 21, accurately weigh the raw materials using the electronic scale 13, and then, under the action of the material - conveying frame 3, achieve the function of separating the iron powder from other raw materials and the function of conveying the raw materials. During the conveying process, use the mixing comb plates 14 inside the material - conveying frame 3 to perform pre - mixing treatment on other raw materials, and at the same time achieve the drying function of the iron powder;

[0058] S2. Conveying of raw materials: Use the translational electric control slide rail 8 and the lifting electric control slide rail 5 to convey the furnace charge conveying member 23 to the feeding port at the top of the smelting furnace, achieving the function of one - time conveying of all batches of raw materials, and there is no need to repeat the conveying process;

[0059] S3. Final mixing of raw materials: By rotating the conveying groove inside the furnace charge to the feeding nozzle 11, the pre - mixed raw materials inside the conveying groove are mixed with the dried iron powder, and at the same time, the heating agent and oxide powder are automatically added, achieving the function of simultaneous feeding and mixing of raw materials, eliminating the blank period in the smelting process, and improving the smelting efficiency.

[0060] When the present invention is in use, the conveyor belt 1 drives the material - conveying frame 3 to move intermittently. When the material - conveying frame 3 moves to the position of the backing plate 21, the staff place various raw materials on the backing plate 21 correspondingly, place the iron powder inside the circular trough, and place the remaining raw materials inside the square trough. Use the electronic scale 13 to accurately weigh various raw materials to facilitate the ratio of raw materials. When the conveyor belt 1 continues to work, the vibration slide rail 12 cooperates with the connecting slider 16 to drive the material - conveying frame 3 to move. The material - conveying frame 3 can push the raw materials on the backing plate 21 flat onto the vibrating bottom plate 19 to achieve the conveying of raw materials. When the mixing comb plate 14 inside the material - conveying frame 3 moves between the repulsive alternating magnetic block 34 and the traction alternating magnetic block 4 (the conveyor belt 1 stops moving), under the combined action of the magnetic repulsive force between the repulsive alternating magnetic block 34 and the mixing comb plate 14 and the magnetic attractive force between the traction alternating magnetic block 4 and the mixing comb plate 14, the mixing comb plate 14 moves in the square trough inside the material - conveying frame 3 (there is a certain distance between the adjacent repulsive alternating magnetic block 34 and the traction alternating magnetic block 4 on the same side to avoid interference between their magnetic fields), and resets under the action of the next group of repulsive alternating magnetic block 34 and traction alternating magnetic block 4. Repeating this process realizes the pre - mixing of the raw materials inside the square trough, provides convenience for the final mixing of subsequent raw materials, reduces the time for the final mixing of subsequent raw materials. At the same time, under the action of the vibration motor 20 installed at the bottom of the vibrating bottom plate 19, the vibrating bottom plate 19 can be driven to vibrate, causing the raw materials inside the square trough to vibrate accordingly (under the action of the elastic sealing plate 2, the material - conveying frame 3 can be sealed to prevent the powdered raw materials from dispersing during the vibration process), improving the sufficiency of the pre - mixing of the raw materials inside the square trough (when the conveyor belt 1 is working, the vibration motor 20 stops working). During the conveying process, the iron powder inside the circular trough is dried under the heating action of the electromagnetic induction coil 15;

[0061] When the material feeding frame 3 drives the raw materials to move to the mixing and discharging port 1902 and the iron powder discharging port 1901, the pre-mixed raw materials inside the square material tank enter the separating hopper 6 through the mixing and discharging port 1902, and the dried iron powder enters the separating hopper 6 through the iron powder discharging port 1901, and then enters the conveying trough. After that, the intermittent motor 18 continues to drive the charge conveying member 23 to rotate, so that the conveying trough at the next position rotates to the separating hopper 6. Then, the conveyor belt 1 continues to drive, so that the next material feeding frame 3 moves to the mixing and discharging port 1902 and the iron powder discharging port 1901, and the above operations are repeated, so that the raw materials are divided into multiple batches and sequentially placed inside the conveying trough for temporary storage;

[0062] When all batches of raw materials are placed inside the conveying trough, first use the translation electric control slide rail 8 to drive the moving housing 7 to move horizontally, so that it moves out from under the vibrating bottom plate 19, and then use the lifting electric control slide rail 5 to drive the translation electric control slide rail 8 to rise, thereby driving the charge conveying member 23 to rise, and then driving the moving housing 7 to rise. Finally, under the driving action of the moving vehicle 10, drive the moving housing 7 to move, so that the discharging nozzle 11 under the moving housing 7 is aligned with the feeding port at the top of the smelting furnace, and all batches of raw materials can be conveyed to the feeding port at the top of the smelting furnace at one time, without repeating the feeding operation, realizing the feeding function of the raw materials;

[0063] When discharging is required, first turn on the upper opening and closing electromagnet 25, and use the magnetic repulsion force between the upper opening and closing electromagnet 25 and the upper opening and closing plate 30 to push the upper opening and closing plate 30 to move, so that the discharging interface at the bottom end of the built-in mixing cylinder 27 is opened (the opening time of the discharging interface is determined by the energization time of the upper opening and closing electromagnet 25, ensuring that the opening time of the discharging interface is the same each time, and thus ensuring that the amount of the heating agent and the oxide powder entering the conveying trough each time is the same. The inner wall of the built-in mixing cylinder 27 is smooth, and at the same time, under the stirring action of the turning plate 29, when the amount of the heating agent and the oxide powder in the built-in mixing cylinder 27 is small, it can prevent the heating agent and the oxide powder from accumulating at the edge), and the heating agent and the oxide powder inside the built-in mixing cylinder 27 enter the conveying trough through the discharging interface and the feeding interface at the bottom end of the conveying trough, and come into contact with the pre-mixed raw materials inside the conveying trough;

[0064] Then turn on the lower opening and closing electromagnet 35, and use the magnetic repulsion force between the lower opening and closing electromagnet 35 and the lower opening and closing plate 31 to push the lower opening and closing plate 31 to move, so that the discharging port at the bottom end of the moving housing 7 is opened, so that all the raw materials inside the conveying trough enter the discharging nozzle 11.
