Description

Technical Field

[0001] This utility model belongs to the field of metal particle crushing technology, and in particular relates to a crushing device for ferroalloy particle smelting. Background Technology

[0002] Ferroalloy particle smelting and crushing equipment is a special device for processing ferroalloy particles. It is mainly used to crush large pieces or larger particles of ferroalloy into small particles or powder suitable for smelting, so that the ferroalloy particles can react more fully with flux, reducing agent, etc. during the smelting process, thereby improving smelting efficiency. Moreover, the crushed particles are easy to transport and store, which also facilitates subsequent smelting operations.

[0003] The feed inlet length of existing crushing devices is usually much shorter than the length of the crushing roller. After the raw material is put in, it is easy to concentrate the crushing in a local area, which cannot make full use of the effective working area of ​​the crushing roller, resulting in a decrease in the crushing efficiency of the raw material. In addition, the wear of the crushing roller in the raw material accumulation area is significantly higher than that in other parts, resulting in excessive wear of the crushing roller in a local area, shortening its overall service life and increasing the production cost of the plant.

[0004] To address the aforementioned problems, this application proposes a ferroalloy particle smelting and crushing device. Utility Model Content

[0005] The purpose of this invention is to provide a ferroalloy particle smelting and crushing device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a crushing device for ferroalloy particle smelting, including a crushing box with two crushing rollers rotatably installed inside the crushing box. A feed hopper is provided on the upper left side of the crushing box, including two spreading plates, which are symmetrically arranged inside the crushing box and located above the crushing rollers. The left end of the spreading plate is higher than the right end. Two rotating plates are rotatably installed inside the crushing box. The rotating plates are connected to the spreading plates through connecting plates. After the raw material enters the crushing box, it is spread along the inclined spreading plates. The two spreading plates form a channel for the raw material to fall through through rotation.

[0008] Two cleaning rollers are rotatably installed inside the crushing chamber and have bristles on their outer walls. The bristles contact the surface of the crushing rollers, and the cleaning rollers achieve cleaning by rotating to make the bristles contact the surface of the crushing rollers.

[0009] Furthermore, the right side of the crushing box is provided with an installation plate that is rotatably connected to the rotating shaft. The outer wall of the rotating shaft is provided with two symmetrically distributed bevel gears. The right ends of the two rotating plates are provided with bevel gears, and the two bevel gears are respectively meshed with the two bevel gears. One end of the rotating shaft is connected to the drive shaft of the motor.

[0010] Furthermore, the left side of the crushing box is provided with two motors II with opposite rotation directions of the drive shafts, and the drive shafts of the two motors II are respectively connected to the ends of the two crushing rollers.

[0011] Furthermore, the right ends of the crushing roller and the cleaning roller are connected to pulley two and pulley one respectively via connecting shafts, and pulley one and pulley two are connected by belts.

[0012] Furthermore, the upper surface of the paving plate is provided with evenly distributed receiving grooves.

[0013] Furthermore, a connecting square tube connects the crushing box and the feeding hopper, and a second rotating shaft is installed inside the connecting square tube. Four material distribution plates are distributed around the outer circumference of the second rotating shaft, and the end of the second rotating shaft is connected to the drive shaft of the third motor.

[0014] Furthermore, the rotating plate is tilted to guide the raw material onto the spreading plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses an inclined spreading plate to disperse the raw materials. When the spreading plate rotates, a gap is formed in the middle for the raw materials to pass through, thereby expanding the material falling area and making the raw materials fall evenly on the crushing roller. This allows the effective working area of ​​the crushing roller to be fully utilized, improving the raw material crushing efficiency, shortening the smelting preparation time, and thus improving the overall production efficiency. At the same time, it can also effectively avoid the problem of excessive wear caused by local accumulation of raw materials.

[0017] This invention uses a crushing roller to crush raw materials. A cleaning roller rotates simultaneously with the crushing roller, and the bristles of the cleaning roller sweep across the crushing roller to clean its surface. This effectively removes debris that adheres to or gets stuck between the crushing teeth, preventing debris from accumulating on the crushing roller and preventing residual debris from affecting the crushing effect of the crushing teeth on the raw materials. This improves the crushing rate of the raw materials and further shortens the raw material processing time.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1 As shown in Figure 5, this utility model is a crushing device for ferroalloy particle smelting, including a crushing box 1 with two crushing rollers 2 rotatably installed inside the crushing box 1. A feed hopper is provided on the upper left side of the crushing box 1, including two spreading plates 3, which are symmetrically arranged inside the crushing box 1 and located above the crushing rollers 2. The left end of the spreading plate 3 is higher than the right end. Two rotating plates 4 are rotatably installed inside the crushing box 1. The rotating plates 4 are connected to the spreading plates 3 through connecting plates 401. After the raw material enters the crushing box 1, it is spread along the inclined spreading plates 3. The two spreading plates 3 form a channel for the raw material to fall through by rotation. Two cleaning rollers 8 are rotatably installed inside the crushing box 1 and have bristles on their outer walls. The bristles are in contact with the surface of the crushing rollers 2. The cleaning rollers 8 achieve cleaning by rotating to make the bristles contact the surface of the crushing rollers 2.

[0030] This embodiment provides a smelting and crushing device. The inclined material spreading plate 3 disperses the raw material. When the material spreading plate 3 rotates, a channel is naturally formed between the two material spreading plates 3, allowing the raw material to pass through and widening the material drop range. This ensures that the raw material can be evenly covered on the crushing roller 2, making full and efficient use of the effective working area of ​​the crushing roller 2. This significantly improves the crushing efficiency of the raw material and effectively shortens the preparation time before smelting, thereby accelerating the overall production process. In addition, it can effectively prevent excessive wear of the crushing roller 2 caused by local accumulation of raw material, ensuring the stable operation of the equipment.

[0031] When the crushing roller 2 crushes the raw material, the cleaning roller 8 rotates along with the crushing roller 2. The bristles on the cleaning roller 8 sweep across the surface of the crushing roller 2, effectively removing debris that is attached to or stuck between the crushing teeth. This prevents the accumulation of debris on the crushing roller 2, ensuring that the crushing teeth always maintain a good working condition and are not disturbed by residual debris, thereby increasing the crushing speed of the raw material and further reducing the processing time of the raw material.

[0032] The crushing box 1 has an installation plate on its right side that is rotatably connected to a rotating shaft 701. The outer wall of the rotating shaft 701 has two symmetrically distributed bevel gears 6. The right ends of the two rotating plates 4 are connected by a connecting shaft and have bevel gears 5. The two bevel gears 6 are respectively meshed with the two bevel gears 5. One end of the rotating shaft 701 is connected to the drive shaft of the motor 7. The motor 7 drives the two bevel gears 6 to rotate synchronously. The bevel gears 6 drive the two rotating plates 4 to rotate synchronously in opposite directions through the meshing bevel gears 5. The rotation axis of the rotating plates 4 is parallel to the horizontal plane. The rotating plates 4 drive the material spreading plates 3 to rotate in opposite directions, so that the material spreading plates 3 are pressed together to form a blocking plate or to form a channel between the material spreading plates 3.

[0033] The crushing box 1 has two motors 11 with opposite rotation directions on the left side, and the transmission shafts of the two motors 11 are respectively connected to the ends of the two crushing rollers 2. The two motors 11 drive the two crushing rollers 2 to rotate in opposite directions, so that the crushing rollers 2 crush the raw materials.

[0034] The right ends of the crushing roller 2 and the cleaning roller 8 are connected to pulley 2 10 and pulley 1 9 respectively via connecting shafts. The pulley 1 9 and pulley 2 10 are connected by a belt. When the crushing roller 2 rotates, the cleaning roller 8 is driven to rotate by the action of pulley 1 9, pulley 2 10 and belt, so that the bristles on the cleaning roller 8 clean the surface of the crushing roller 2.

[0035] The upper surface of the spreading plate 3 is provided with evenly distributed receiving grooves 301. The receiving grooves 301 are used to slow down the downward speed of the raw materials and to accommodate some of the falling raw materials, preventing all the raw materials from rolling to the lowest end of the spreading plate 3 and causing the raw materials to accumulate, so that the raw materials can be more evenly distributed on the spreading plate 3.

[0036] The crushing box 1 and the feed hopper are connected by a connecting square tube 12. A rotating shaft 1401 is installed inside the connecting square tube 12. Four material distribution plates 13 are distributed around the outer circumference of the rotating shaft 1401. The end of the rotating shaft 1401 is connected to the drive shaft of the motor 14. After the raw material is put into the feed hopper, the motor 14 drives the material distribution plates 13 to rotate, so that the raw material intermittently enters the crushing box 1 through the connecting square tube 12, avoiding the accumulation of raw material, ensuring that the crushing roller 2 is evenly loaded, and improving the crushing efficiency. When the connecting square tube 12 is closed by the material distribution plates 13, it provides an opportunity for the two material distribution plates 3 to stick together to form a blocking plate.

[0037] The rotating plate 4 is tilted to guide the raw materials to the spreading plate 3, so that the raw materials can fall onto the spreading plate 3.

[0038] It is understood that this utility model can disperse the raw materials so that they fall evenly onto the crushing roller 2, making full use of the effective working area of ​​the crushing roller 2. Secondly, it can clean the crushing roller 2 during crushing to prevent debris from adhering to the surface of the crushing roller 2 and affecting the crushing efficiency of the crushing teeth.

[0039] In a specific application of this embodiment, the raw material enters the connecting square tube 12 through the feed hopper. The motor 3 14 drives the rotating shaft 2 1401 to rotate the distribution plate 13, causing the raw material to pass through the connecting square tube 12 and enter the crushing box 1. Inside the crushing box 1, the raw material falls onto the spreading plate 3. The symmetrically arranged spreading plates 3 are inclined with the left side higher than the right side, and the raw material rolls along the spreading plates 3 to disperse it. The surface of the spreading plate 3 has receiving grooves 301 to slow down the downward speed of the raw material. The two spreading plates 3 are fixedly connected to the rotating plate 4 by the connecting plate 401. Motor 7 drives shaft 701 to rotate, which meshes with bevel gear 5 through bevel gear 6, causing rotating plate 4 to swing, thereby forming a material drop channel between the two material spreading plates 3, so that the raw material falls evenly between the two crushing rollers 2. The crushing rollers 2 are driven by motor 11 to rotate in the opposite direction to crush the raw material. Cleaning roller 8 is linked with crushing roller 2 through pulley 9, pulley 10 and belt. The bristles contact the surface of crushing roller 2 and rotate in the opposite direction to clean the surface of crushing roller 2. The crushed particles are discharged from the bottom of crushing box 1.
