Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to a particle steel slag impact crushing device. Background Technology

[0002] In the field of industrial solid waste resource utilization, particulate steel slag, as a major byproduct of steelmaking, has high recycling value due to its content of metallic iron and usable non-metallic minerals. Crushing particulate steel slag is a key step in realizing its resource utilization. Crushing breaks down particulate steel slag into materials of different particle sizes, facilitating subsequent separation of metallic iron and reprocessing of non-metallic minerals.

[0003] Currently, most devices used for crushing granular steel slag employ the principle of impact crushing. Their core structure typically includes a feed channel, impact hammers, a crushing chamber, and a discharge port. During operation, granular steel slag enters the crushing chamber through the feed channel and is crushed by collision and impact under the action of the high-speed rotating impact hammers. The crushed material is then discharged from the discharge port.

[0004] However, existing particle steel slag impact crushing devices have a significant drawback: the feed channel is usually a fixed structure. This fixed structure results in the particle steel slag falling at a relatively fixed point when entering the crushing chamber, mostly concentrated in a specific area within the crushing chamber.

[0005] This problem of concentrated material impact points can lead to a series of adverse consequences: First, because the material is concentrated in the same area of ​​the crushing chamber for a long time, the wear rate of the impact hammer and the inner wall of the crushing chamber in that area will be accelerated, which will seriously shorten the service life of the equipment and increase the maintenance cost and downtime. Second, the uneven distribution of the concentrated material in the crushing chamber will result in insufficient contact between the impact hammer and the material. Some materials may not be crushed effectively due to insufficient impact, resulting in uneven particle size of the crushed material, which will affect the subsequent sorting and processing quality.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] The purpose of this invention is to provide a particle steel slag impact crushing device to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a particle steel slag impact crushing device, including a housing with a crushing chamber inside. A feed inlet communicating with the crushing chamber is provided at the upper part of the housing, and a discharge outlet communicating with the crushing chamber is provided at the lower part. A crushing component is provided inside the crushing chamber. The device is characterized in that: a feed shell is installed at the port of the feed inlet; a movable groove extending along its length is recessed on the inner wall of the feed shell; a sliding seat is slidably installed inside the movable groove; a guide plate adapted to the size of the groove opening is rotatably installed at the opening of the movable groove; a connecting rod is hinged to the sliding seat; the other end of the connecting rod is hinged to the guide plate; and a driving component is provided inside the movable groove to drive the sliding seat to slide along the inner wall of the movable groove to adjust the pitch angle of the guide plate.

[0009] Furthermore, the crushing assembly includes a drive shaft, a crushing roller, and an impact liner. The drive shaft is rotatably mounted inside the housing. Both ends of the crushing roller are rotatably connected to the housing via bearing seats. The crushing roller is mounted on the drive shaft. Hammers are detachably mounted on the outer periphery of the crushing roller. The impact liner is fixed to the inner wall of the crushing chamber, and a crushing gap is formed between the impact liner and the hammers on the outer periphery of the crushing roller.

[0010] Furthermore, it also includes a transmission assembly disposed on the outer wall of the housing to drive the drive shaft to rotate. The transmission assembly includes a driven wheel, a drive motor, a driving wheel and a synchronous belt. The driven wheel is coaxially and fixedly connected to the drive motor. The driving end of the drive motor is connected to the driving wheel. The driven wheel and the driving wheel are driven by the synchronous belt.

[0011] Furthermore, the impact liner includes at least two arc-shaped liners, each of which is distributed circumferentially along the crushing chamber, and a material return channel is formed between two adjacent arc-shaped liners.

[0012] Furthermore, it also includes an adjusting component for adjusting the crushing gap. The adjusting component includes a mounting screw, one end of which is rotatably connected to the impact liner via a rotating sleeve. An mounting shell is installed on the outer wall of the housing, and the mounting screw is threadedly connected inside the mounting shell. A limit plate is also threadedly connected to the outer wall of the mounting screw.

[0013] Furthermore, the driving component includes a servo motor installed inside the movable slot, the driving end of the servo motor is rotatably connected to an adjusting screw, the other end of the adjusting screw is connected to the inner wall of the movable slot through a bearing, and the sliding seat is threadedly connected to the adjusting screw.

[0014] Furthermore, it also includes an airbag located at the edge of the top surface of the guide plate, and an air pump installed on the bottom surface of the guide plate for inflating / contracting the airbag by filling it with gas.

[0015] Furthermore, a protective shell is installed on the bottom surface of the guide plate, and the protective shell is installed inside the air pump.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the guide plate inside the feed shell is angle-adjustable through a drive component. Combined with the buffering effect of the airbag, the feeding trajectory can be dynamically adjusted according to the particle size, hardness, and other characteristics of the steel slag particles. At the same time, the gap between the impact liner and the hammer in the crushing component can be flexibly adjusted through the installation screw, so that the feed rate, the drop position and the crushing intensity are precisely matched. This can not only process steel slag raw materials of different specifications, but also stably control the output particle size, greatly improving the equipment's adaptability to complex working conditions.

[0018] 2. When processing steel slag with larger particle size and harder texture, this utility model can increase the inflation height of the airbag to form a higher protrusion. By changing the contact point and force direction between the steel slag and the guide plate, the feeding projection angle can be increased, allowing the steel slag to more forcefully impact the impact liner inside the crushing chamber, thus enhancing the initial crushing force. For steel slag with smaller particle size and more fragile texture, the inflation height of the airbag can be reduced, and the feeding projection angle can be decreased, allowing the steel slag to enter the action area of ​​the crushing roller and hammer more smoothly, avoiding energy waste caused by excessive impact and improving crushing efficiency.

[0024] 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a particle steel slag impact crushing device, including a housing 1, which has a crushing chamber inside. A feed inlet 2 communicating with the crushing chamber is provided at the upper part of the housing, and a discharge outlet 3 communicating with the crushing chamber is provided at the lower part of the housing. A crushing component is provided inside the crushing chamber. A feed shell 4 is installed at the port of the feed inlet 2. A movable groove 16 extending along its length is recessed in the inner wall of the feed shell 4. A sliding seat 19 is slidably installed inside the movable groove 16. A guide plate 21 adapted to the size of the groove opening is rotatably installed at the opening of the movable groove 16. A connecting rod 20 is hinged to the sliding seat 19. The other end of the connecting rod 20 is hinged to the guide plate 21. A driving component is provided inside the movable groove 16 to drive the sliding seat 19 to slide along the inner wall of the movable groove 16 to adjust the pitch angle of the guide plate 21.

[0026] Specifically, when the granular steel slag enters from the feed inlet 2, the driving component drives the sliding seat 19 to slide along the movable groove 16, and drives the guide plate 21 to rotate through the connecting rod 20, adjusting the pitch angle to change the falling trajectory.

[0027] As a technical optimization of this utility model, the crushing assembly includes a drive shaft 5, a crushing roller 6, and an impact liner 11. The drive shaft 5 is rotatably installed inside the housing 1. The two ends of the crushing roller 6 are rotatably connected to the housing 1 through bearing seats. The crushing roller 6 is mounted on the drive shaft 5. Hammers are detachably installed on the outer periphery of the crushing roller 6. The impact liner 11 is fixed to the inner side wall of the crushing chamber, and a crushing gap is formed between the impact liner 11 and the hammers on the outer periphery of the crushing roller 6.

[0028] Specifically, the drive shaft 5 drives the crushing roller 6 to rotate, and the outer peripheral hammer impacts the steel slag at high speed. The steel slag is repeatedly crushed by collision within the crushing gap between the hammer and the impact liner 11.

[0029] As a technical optimization of this utility model, it also includes a transmission assembly disposed on the outer wall of the housing 1 to drive the drive shaft 5 to rotate. The transmission assembly includes a driven wheel 7, a drive motor 8, a drive wheel 9 and a synchronous belt 10. The driven wheel 7 and the drive motor 8 are coaxially fixedly connected. The drive end of the drive motor 8 is connected to the drive wheel 9. The driven wheel 7 and the drive wheel 9 are transmitted through the synchronous belt 10.

[0030] Specifically, the drive motor 8 transmits power to the drive shaft 5 through the drive wheel 9, the synchronous belt 10, and the driven wheel 7, thereby achieving stable high-speed rotation of the crushing roller 6.

[0031] As a technical optimization of this utility model, the impact liner 11 includes at least two arc-shaped liners, each arc-shaped liner is distributed circumferentially along the crushing chamber, and a material return channel is formed between two adjacent arc-shaped liners.

[0032] Specifically, the arc-shaped impact liner 11 guides the steel slag to rebound and form a cyclic impact, and the return channel of the adjacent liner allows the substandard material to re-enter the crushing area.

[0033] As a technical optimization of this utility model, it also includes an adjusting component for adjusting the crushing gap. The adjusting component includes a mounting screw 13. One end of the mounting screw 13 is rotatably connected to the impact liner 11 through a rotating sleeve 14. An mounting shell 12 is installed on the outer wall of the housing 1. The mounting screw 13 is threadedly connected to the mounting shell 12. A limit plate 15 is also threadedly connected to the outer wall of the mounting screw 13.

[0034] Specifically, rotating the mounting screw 13 can push the impact liner 11 to move through the rotating sleeve 14, adjusting the crushing gap with the hammer, and fixing the position of the limiting plate 15 to prevent displacement.

[0035] As a technical optimization of this utility model, the driving component includes a servo motor 17 installed inside the movable slot 16. The driving end of the servo motor 17 is rotatably connected to an adjusting screw 18. The other end of the adjusting screw 18 is connected to the inner wall of the movable slot 16 through a bearing. The sliding seat 19 is threadedly connected to the adjusting screw 18.

[0036] Specifically, the servo motor 17 drives the adjusting screw 18 to rotate, precisely controlling the displacement of the sliding seat 19, thereby achieving precise adjustment of the angle of the guide plate 21.

[0037] As a technical optimization of this utility model, it also includes an airbag 22 disposed at the edge of the top surface of the guide plate 21, and an air pump 24 installed on the bottom surface of the guide plate 21 for filling the airbag 22 with gas to inflate / contract the airbag 22.

[0038] Specifically, the air pump 24 inflates and deflates the air bag 22, causing it to expand / contract and conform to the surface of the steel slag, preventing material from splashing during feeding. This can increase the inflation height of the air bag, making it form a higher protrusion. By changing the contact point and force direction between the steel slag and the guide plate, the feeding projection angle is increased, allowing the steel slag to more powerfully impact the impact liner inside the crushing chamber, thus enhancing the initial crushing force.

[0039] As a technical optimization of this utility model, a protective shell 23 is installed on the bottom surface of the guide plate 21, and the protective shell 23 covers the inside of the air pump 24.

[0040] Specifically, the protective shell 23 covers the air pump 24, isolating it from the impact of steel slag and dust pollution, extending the service life of the air pump 24, reducing the frequency of equipment maintenance, and ensuring the stable operation of the feeding adjustment system.

[0041] Working principle: Particle steel slag enters the device through inlet 2 and first contacts the guide plate 21 inside the feed shell 4. The driving component drives the adjusting screw 18 to rotate, causing the sliding seat 19 to slide along the movable groove 16. Through the connecting rod 20, the guide plate 21 is pulled to rotate around the groove opening, realizing the pitch angle adjustment. The angle range can be controlled by the stroke of the driving component. This process can adjust the falling trajectory according to the steel slag particle size and feed rate to avoid material concentrating and impacting a certain area of ​​the crushing chamber. At the same time, the air bag 22 can be inflated / deflated by the air pump 24 to conform to materials of different particle sizes and prevent steel slag from splashing during feeding. The protective shell 23 protects the air pump 24 from material impact.

[0042] After the steel slag guided by the guide plate 21 enters the crushing chamber, the transmission assembly is activated: the drive motor 8 drives the driven wheel 7 to rotate via the drive wheel 9 and the synchronous belt 10, which in turn drives the drive shaft 5 to rotate, causing the crushing roller 6 to rotate at a set speed. The hammers on the outer periphery of the crushing roller 6 rotate with it, and the linear velocity generated creates a violent impact on the steel slag. The impacted steel slag bounces off the impact liner 11 and collides again with subsequent steel slag or hammers, repeatedly crushing within the crushing gap formed by the crushing roller 6 and the impact liner 11. The arc-shaped liner design and the return channel between adjacent liners can extend the residence time of the material in the crushing chamber, ensuring thorough crushing.

[0043] If the discharge particle size needs to be adjusted, it can be done through the adjusting mechanism: rotate the mounting screw 13 to move it axially along the mounting shell 12, and push the impact liner 11 closer to or further away from the crushing roller 6 through the rotating sleeve 14, thus changing the crushing gap. The limiting plate 15 can fix the adjusted position to prevent the gap from shifting due to vibration during operation. Steel slag that meets the particle size requirements is discharged through the discharge port 3, completing the crushing process.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
