Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, and in particular to a raw material mixing processing equipment and a 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 the molybdenum concentrate into an internal combustion rotary kiln, and use the heat generated by the ignition of coal to oxidize the molybdenum concentrate in the kiln to emit 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 crushed by a hammer crusher for standby use. The smelting of ferromolybdenum alloy mainly adopts the aluminothermic reduction method. The raw materials mainly include industrial molybdenum oxide, ferrosilicon powder, aluminum powder, sodium nitrate, iron ore powder, steel scraps, heating agent and oxide powder. The raw materials need to be mixed to form furnace charge. When the smelting furnace is smelting, materials are added in batches. Since aluminum powder, heating agent and oxide powder in the raw materials cannot be stacked together, the charge cannot be stored. The charge must be smelted immediately after mixing. Since the charge needs to be added in batches, the raw materials can only be mixed before being added, which makes the smelting process have a long window period, significantly reducing the smelting efficiency. In addition, each time the charge is added, the charge needs to be transported to the feed port at the top of the smelting furnace, which further reduces the smelting efficiency. Therefore, a raw material mixing processing equipment and method for ferromolybdenum production are proposed to solve the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 8, a raw material mixing and processing equipment for ferromolybdenum production, comprising a vibration bottom plate 19 set 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 (two conveyor belts 1 and the support plate are provided and symmetrically arranged, and the conveyor belt 1 is intermittently rotated), the bottom end of the vibration bottom plate 19 is fixedly connected to one end (the conveying initial end of the conveyor belt 1), a plurality of electronic scales 13 are installed on the L-shaped mounting plate, and a pad 21 flush with the vibration bottom plate 19 is provided on the top of the electronic scale 13; It should be noted that the electronic scale 13 is used to weigh various raw materials individually to facilitate the proportioning of the raw materials.

[0020] It should be noted that the L-shaped mounting plate is used to mount the electronic scale 13 , and the pad 21 is flush with the vibration bottom plate 19 , which can ensure that the feed frame 3 pushes the raw materials flat onto the vibration bottom plate 19 , facilitating the transportation of the raw materials.

[0021] The surface of the conveyor belt 1 is evenly provided with a plurality of vibrating slide rails 12, the inner side of the vibrating slide rail 12 is slidably provided with a connecting slide block 16, one end of the connecting slide block 16 is fixedly connected with a feeding frame 3, and the feeding frame 3 is connected to the inner wall of the vibrating slide rail 12 through a resisting spring 17; It should be noted that: the resistance spring 17 is in a compressed state, and cooperates with the connecting slider 16 to make the bottom end of the feed frame 3 close to the vibrating bottom plate 19, ensuring that the feed frame 3 can realize the raw material conveying function during the movement. At the same time, during the vibration of the vibrating bottom plate 19, the feed frame 3 vibrates synchronously with the vibrating bottom plate 19 under the elastic force of the resistance spring 17, ensuring that during the vibration process, the bottom end of the feed frame 3 is always in close contact with the vibrating bottom plate 19 to avoid leakage of raw materials.

[0022] A circular material trough and a square material trough are arranged inside the feeding frame 3, a mixing comb plate 14 is slidably arranged inside the square material trough, an electromagnetic induction coil 15 is arranged inside the feeding frame 3 around the circular material trough, and a plurality of traction alternating magnetic blocks 4 and repulsion alternating magnetic blocks 34 connected to the support plate are alternately arranged on both sides of the conveyor belt 1, and the top ends of the traction alternating magnetic blocks 4 and the repulsion alternating magnetic blocks 34 are fixedly connected with an elastic sealing plate 2; It should be noted that the alternating order of the traction alternating magnetic blocks 4 (which are the magnetic blocks of the magnetic attraction mixing comb plate 14) and the repulsion alternating magnetic blocks 34 (which are the magnetic blocks of the magnetic repulsion mixing comb plate 14) on both sides of the conveyor belt 1 is opposite, that is, the arrangement order of the traction alternating magnetic blocks 4 and the repulsion alternating magnetic blocks 34 on the left side of the conveyor belt 1 is that the traction alternating magnetic blocks 4 and the repulsion alternating magnetic blocks 34 appear alternately, and the appearance order of the two on the right side of the conveyor belt 1 is that the repulsion alternating magnetic blocks 34 and the traction alternating magnetic blocks 4 appear alternately.

[0023] It should be noted that the inside of the circular trough is used to place iron powder, because the iron powder needs to be dried before mixing, and the square 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, provide convenience for the final mixing of subsequent raw materials, and reduce the time for the final mixing of subsequent raw materials.

[0024] A pair of moving vehicles 10 are provided at the conveying end of the conveyor belt 1 (the moving vehicles 10 are electric vehicles, and can be driven by an external controller). The top of the moving vehicles 10 is fixedly connected to a lifting electric control slide rail 5 through a vertical plate, and the inner side of the lifting electric control slide rail 5 is slidably connected to a translation electric control slide rail 8 through a lifting slide seat, and a translation slide seat is slidably provided on the inner side of the translation electric control slide rail 8; It should be noted that the lifting electric-controlled slide rail 5 and the translation electric-controlled slide rail 8 are both existing technologies, and their specific structures and working principles are not described here in detail.

[0025] It should be noted that the lifting electric-controlled slide rail 5 and the translation electric-controlled slide rail 8 cooperate with the mobile vehicle 10 to realize the lifting and translation functions of the aluminum material conveying parts, and can convey all batches of raw materials to the feed port at the top of the smelting furnace at one time, realizing the raw material loading function.

[0026] One end of the translational slide is fixedly connected to a moving shell 7, the top of the moving shell 7 is fixedly connected to a dividing hopper 6, the interior of the dividing hopper 6 is fixedly connected to a material discharge baffle 22 (the material discharge baffle 22 can separate the iron powder and other raw materials to prevent the two from mixing when entering the conveying trough, because the iron powder has just been heated and dried at this time, and its temperature is relatively high, and it needs to be cooled before it can be mixed with other raw materials), the bottom end of the moving shell 7 is fixedly connected to a material discharge nozzle 11, a furnace material conveying member 23 is rotatably provided inside the moving shell 7, and a conveying trough is provided on the inner circumference of the furnace material conveying member 23 (the number of conveying troughs is the same as the number of batches of raw materials, so as to facilitate the separate storage of each batch of raw materials), a conveying baffle 24 is fixedly connected to the interior of the conveying trough (the conveying baffle 24 prevents the iron powder from mixing with other raw materials inside the conveying trough, and gives the iron powder enough cooling time), a transfer groove is provided at the center of the furnace material conveying member 23, and a built-in mixing barrel 27 is rotatably connected to the inner side of the transfer groove.

[0027] Furthermore, a mixing discharge port 1902 adapted to the square trough and an iron powder discharge port 1901 adapted to the circular trough are provided inside the vibration base plate 19 near the conveying end of the conveyor belt 1, and a vibration motor 20 for driving the vibration base plate 19 to vibrate is installed at the bottom end of the vibration base plate 19.

[0028] It should be noted that the setting of the mixing discharge port 1902 facilitates the premixed raw materials in the square trough inside the feeding frame 3 to enter the partition hopper 6, and the setting of the iron powder discharge port 1901 facilitates the iron powder dried in the circular trough to enter the partition hopper 6.

[0029] Furthermore, an intermittent motor 18 is installed on the outer side of the movable housing 7, and the output shaft of the intermittent motor 18 passes through the movable housing 7 and is fixedly connected to the charge conveying member 23 (the intermittent motor 18 drives the charge conveying member 23 to rotate intermittently).

[0030] A feeding port connected to the feeding nozzle 11 is provided at the bottom end of the movable shell 7, a lower opening is provided on the side wall of the movable shell 7, a lower opening is slidably connected to the inner wall of the feeding port with a lower opening and closing plate 31, one end of the lower opening and closing plate 31 is connected to the side wall of the movable shell 7 through a lower return spring 32, further, a lower opening and closing electromagnet 35 that magnetically repels each other is installed on the other side of the movable shell 7 facing the lower opening and closing plate 31, a discharging interface is provided at the bottom end of the built-in mixing barrel 27, an upper opening that is aligned with the discharging interface is provided on the side wall of the movable shell 7, an upper opening is slidably connected to the inner wall of the discharging interface with an upper opening and closing plate 30, one end of the upper opening and closing plate 30 is fixedly connected to one side of the movable shell 7 through an upper return spring, and an upper opening and closing electromagnet 25 that magnetically repels each other is installed on the other side of the movable shell 7 facing the upper opening and closing plate 30.

[0031] It should be noted that: when it is necessary to pour the raw materials in the conveying trough into the smelting furnace, the conveying trough is rotated to the discharge nozzle 11, and then the upper opening and closing electromagnet 25 is turned on first, and the magnetic repulsion between the upper opening and closing electromagnet 25 and the upper opening and closing plate 30 is used to push the upper opening and closing plate 30 to move, so that the discharge interface at the bottom of the built-in mixing barrel 27 is opened, and the exothermic agent and oxide powder in the built-in mixing barrel 27 enter the conveying trough through the discharge interface and the feed interface at the bottom of the conveying trough to contact the premixed raw materials in the conveying trough; Then, the lower opening and closing electromagnet 35 is turned on, and the magnetic repulsion between the lower opening and closing electromagnet 35 and the lower opening and closing plate 31 is used to push the lower opening and closing plate 31 to move, so that the discharge port at the bottom of the movable shell 7 is opened, so that all the raw materials inside the conveying trough enter the discharge nozzle 11.

[0032] Furthermore, a feed interface is provided at the bottom end of the conveying trough, and a flipping motor 28 is installed on the side wall of the movable shell 7. The output shaft of the flipping motor 28 extends to the inside of the built-in mixing barrel 27 and is fixedly connected to the main shaft, and a plurality of flipping plates 29 are fixedly connected to the surface of the main shaft.

[0033] It should be noted that: a hinged door is provided on the side wall of the movable housing 7 at the built-in mixing barrel 27, which is used to pour the heating agent and oxide powder into the built-in mixing barrel 27; The turning motor 28 drives the main shaft to rotate, and then drives the turning plate 29 to rotate, so as to mix the heating agent and the oxide powder.

[0034] Furthermore, the internal rotation of the discharge nozzle 11 is connected to a relatively arranged rotating shaft, the surface of the rotating shaft is fixedly connected to a discharge mixing plate 9, one end of the discharge mixing plates 9 on both sides is fixedly connected to mutually meshing gears 33, and the outer side wall of the discharge nozzle 11 is installed with a mixing motor 26 connected to one of the rotating shafts.

[0035] It should be noted that the mixing motor 26 drives the rotating shaft to rotate, and then drives the unloading mixing plate 9 to rotate, so as to finally mix the raw materials entering the unloading nozzle 11, and the furnace charge formed after mixing enters the smelting furnace, realizing the function of simultaneous unloading and mixing of raw materials, and eliminating the window period in the smelting process.

[0036] Please refer to Fig. 9 , a processing method proposed by a raw material mixing processing equipment for ferromolybdenum production comprises the following steps: S1. Premixing of raw materials: placing the raw materials in batches on the corresponding pads 21, using the electronic scale 13 to accurately weigh the raw materials, and then under the action of the feeding frame 3, the iron powder and other raw materials are separated and the raw materials are transported. During the transportation process, the mixing comb 14 inside the feeding frame 3 is used to premix other raw materials and realize the drying function of the iron powder; S2, raw material transportation: using the translation electric control slide rail 8 and the lifting electric control slide rail 5, the charge conveying member 23 is conveyed to the unloading port at the top of the smelting furnace, so as to realize the one-time conveying function of all batches of raw materials without repeating the conveying process; S3. Final mixing of raw materials: by rotating the conveying trough inside the furnace charge to the discharge nozzle 11, the premixed raw materials in the conveying trough are mixed with the dried iron powder, and the exothermic agent and oxide powder are automatically added at the same time, so as to realize the function of simultaneous discharge and mixing of raw materials, eliminate the window period in the smelting process, and improve the smelting efficiency.

[0037] When the present invention is used, the conveyor belt 1 is used to drive the feeding frame 3 to move intermittently. When the feeding frame 3 moves to the pad 21, the staff will place various raw materials on the pad 21 accordingly, place the iron powder inside the circular material trough, and place the remaining raw materials inside the square material trough. The electronic scale 13 is used to accurately weigh various raw materials to facilitate the proportioning of the raw materials. When the conveyor belt 1 continues to work, the vibrating slide rail 12 cooperates with the connecting slider 16 to drive the feeding frame 3 to move. The feeding frame 3 can push the raw materials on the pad 21 to the vibrating bottom plate 19 to realize the transportation of the raw materials. When the mixing comb plate 14 inside the feeding frame 3 moves to between the repelling alternating magnetic block 34 and the traction alternating magnetic block 4 (the conveyor belt 1 stops moving), under the combined action of the magnetic repulsion between the repelling alternating magnetic block 34 and the mixing comb plate 14 and the magnetic attraction between the traction alternating magnetic block 4 and the mixing comb plate 14, the mixing comb plate 14 moves in the square material trough inside the feeding frame 3. The repelling alternating magnetic blocks 34 and the pulling alternating magnetic blocks 4 on the same side are moved (there is a certain distance between the adjacent repelling alternating magnetic blocks 34 and the pulling alternating magnetic blocks 4 on the same side to avoid interference of the magnetic fields therebetween), and are reset under the action of the next group of repelling alternating magnetic blocks 34 and the pulling alternating magnetic blocks 4, and this is repeated to achieve the pre-mixing of the raw materials inside the square trough, which facilitates the final mixing of the subsequent raw materials and reduces the time for the final mixing of the subsequent raw materials. At the same time, under the action of the vibration motor 20 installed at the bottom end of the vibration bottom plate 19, the vibration bottom plate 19 can be driven to vibrate, so that the raw materials inside the square trough vibrate (under the action of the elastic sealing plate 2, the feeding frame 3 can be sealed to avoid the dispersion of powdered raw materials during the vibration process), thereby improving the adequacy 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; When the feed frame 3 drives the raw materials to move to the mixing discharge port 1902 and the iron powder discharge port 1901, the premixed raw materials inside the square trough enter the separation hopper 6 through the mixing discharge port 1902, and the dried iron powder enters the separation hopper 6 through the iron powder discharge port 1901, and then enters the conveying trough, and then the intermittent motor 18 continues to drive the furnace material conveying member 23 to rotate, so that the conveying trough at the next position rotates to the separation hopper 6, and then the conveyor belt 1 continues to drive, so that the next feed frame 3 moves to the mixing discharge port 1902 and the iron powder discharge port 1901, and the above operation is repeated, so that the raw materials are divided into multiple batches and placed in the conveying trough for temporary storage in sequence; When all batches of raw materials are placed inside the conveying trough, the translation electric control slide rail 8 is first used to drive the mobile housing 7 to move horizontally, so that it moves out from under the vibrating bottom plate 19, and then the lifting electric control slide rail 5 is used to drive the translation electric control slide rail 8 to rise, thereby driving the furnace material conveying member 23 to rise, and then driving the mobile housing 7 to rise, and finally, under the driving action of the mobile vehicle 10, the mobile housing 7 is driven to move, so that the discharge nozzle 11 under the mobile housing 7 is aligned with the feed port at the top of the smelting furnace, so that all batches of raw materials can be transported to the feed port at the top of the smelting furnace at one time, without repeating the feeding operation, and the raw material feeding function is realized; When it is necessary to discharge the material, first turn on the upper opening and closing electromagnet 25, and use the magnetic repulsion 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 discharge interface at the bottom of the built-in mixing barrel 27 is opened (the opening time of the discharge interface is determined by the power-on time of the upper opening and closing electromagnet 25, ensuring that the opening time of each discharge interface is the same, thereby ensuring that the amount of heating agent and oxide powder entering the conveying trough each time is the same, and the inner wall of the built-in mixing barrel 27 is smoothed, and at the same time, under the stirring action of the turning plate 29, when the amount of heating agent and oxide powder in the built-in mixing barrel 27 is small, the heating agent and oxide powder can be prevented from accumulating at the edge), the heating agent and oxide powder in the built-in mixing barrel 27 enter the conveying trough through the discharge interface and the feed interface at the bottom of the conveying trough, and contact with the premixed raw materials in the conveying trough; Then, the lower opening and closing electromagnet 35 is turned on, and the magnetic repulsion between the lower opening and closing electromagnet 35 and the lower opening and closing plate 31 is used to push the lower opening and closing plate 31 to move, so that the discharge port at the bottom end of the movable shell 7 is opened, so that all the raw materials in the conveying trough enter the discharge nozzle 11, and under the action of the mixing motor 26, the rotating shaft drives the discharge mixing plate 9 to rotate, which can break up and mix the raw materials entering the discharge nozzle 11, and realize the function of simultaneous discharge and mixing, thereby eliminating the window period in the smelting process and improving the smelting efficiency.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
