Description

Technical Field

[0001] This utility model belongs to the field of metallurgical engineering technology, and specifically relates to a device for adjusting the uniformity of material distribution in a sintering machine. Background Technology

[0002] In sintering processes in industries such as metallurgy and steel, the sintering machine plays a crucial role. It is used to process powdery or granular materials into lumpy forms at high temperatures, typically for sintering raw materials such as iron ore, coal, and coke. To improve sintering efficiency and ensure uniformity, the uniformity of material distribution must be effectively controlled. This uniformity directly affects the airflow distribution, heat transfer efficiency, and final quality of the material within the sintering furnace.

[0003] Most existing sintering machines use fixed scrapers or rely solely on a single vibration device to process materials, making it impossible to precisely control the thickness and uniformity of the material during sintering. Many machines lack flexible height adjustment functions, resulting in uneven material distribution and poor sintering effects. Some traditional machines experience slow material discharge or are prone to blockages, especially when processing viscous materials with poor flowability and obstructed discharge. Therefore, a material distribution uniformity adjustment device for sintering machines is proposed to address these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sintering machine material distribution uniformity adjustment device, which aims to improve the problems of the scraper not being able to adjust its height and the material being slow or even blocked during discharge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sintering machine material distribution uniformity adjustment device, comprising a sintering furnace, a hollow column fixedly connected to the outside of the sintering furnace, an adjusting column slidably connected inside the hollow column, a scraper fixedly connected to the bottom of the adjusting column, an outer shell fixedly connected to the outside of the hollow column, an inner shell fixedly connected inside the outer shell, a pin slidably connected inside the inner shell, a spring sleeved on the outside of the pin, a locking component provided on the outside of the pin, a transport component provided in the middle of the sintering furnace, and a stirring component provided on the outside of the sintering furnace.

[0006] Preferably, the mixing assembly includes a mixer, at least two supports are fixedly connected to the outside of the mixer, a discharge pipe is fixedly connected to the bottom of the mixer, a support block is fixedly connected to the bottom of the mixer by at least two fixed brackets, a drive assembly is provided inside the support block, a rotating shaft is rotatably connected to the output end of the drive assembly, a slide rail is fixedly connected to the top of the support block, a slider is slidably connected to the top of the slide rail, one end of the rotating shaft is rotatably connected to the outside of the slider, and a rubber plate is fixedly connected to the outside of the slider by a connecting rod.

[0007] Preferably, the locking assembly includes a pad, which is fixedly connected to the outside of the pin, and a locking block is fixedly connected to the outside of the pad. A U-shaped slot is provided on the outside of the inner shell, and the locking block is slidably connected inside the U-shaped slot.

[0008] Preferably, the transport assembly includes more than one sintering trolley, which is located in the middle of the sintering furnace and directly below the discharge pipe.

[0009] Preferably, the driving component includes a motor, the output end of which is fixedly connected to a disk, the top of which is fixedly connected to an eccentric shaft, and the end of the rotating shaft away from the slider is rotatably connected to the outside of the eccentric shaft.

[0010] Preferably, the adjusting column has multiple circular holes on its outer side, and the pin is inserted into one of the circular holes.

[0011] Preferably, one end of the spring is fixedly connected to one side of the pad, and the other end of the spring abuts against the inner wall of the inner shell.

[0012] Preferably, the rubber plate abuts against the surface of the discharge pipe, and a handle is fixedly connected to the top of the adjusting column.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, the height of the scraper is adjusted by inserting a pin into different circular holes on the adjusting column, thus achieving precise control over the material thickness. Compared to the existing technology that only fixes the scraper position, this adjustment method not only improves the uniformity of the material but also makes the material thickness more controllable during the sintering process, thereby improving the sintering effect.

[0015] 2. In this invention, a motor drives a disc to rotate, and under the action of the eccentric shaft and the rotating shaft, the slider drives the rubber plate to strike the discharge pipe back and forth, thereby accelerating the material flow and preventing material blockage. Compared with existing technologies that rely solely on gravity or mechanical vibration to drive material flow, this design greatly improves the efficiency of material flow, avoids material accumulation in the discharge pipe, and thus improves work efficiency and system stability.

[0023] 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.

[0024] Reference Figure 1 - Figure 3This utility model provides an embodiment of a sintering machine material uniformity adjustment device, comprising a sintering furnace 1, a hollow column 3 fixedly connected to the outside of the sintering furnace 1, an adjusting column 2 slidably connected inside the hollow column 3, a scraper 4 fixedly connected to the bottom of the adjusting column 2, a shell 10 fixedly connected to the outside of the hollow column 3, an inner shell 12 fixedly connected inside the shell 10, a pin 13 slidably connected inside the inner shell 12, a spring 14 sleeved on the outside of the pin 13, a locking component provided on the outside of the pin 13, a transport component provided in the middle of the sintering furnace 1, a stirring component provided on the outside of the sintering furnace 1, and multiple circular holes 16 opened on the outside of the adjusting column 2, with the pin 13 inserted into one of the circular holes 16. The sintering furnace 1 is used to process materials that need to be sintered. The hollow column 3 serves as a sliding passage for the adjusting column 2, facilitating the adjustment of the scraper 4, thereby making the material more uniform during sintering and also adjusting the thickness of the material during sintering. The scraper 4 is used to directly contact the material and ensure that the material is evenly fed into the sintering furnace 1 during sintering. The outer shell 10 supports the various internal components, ensuring their normal operation. The inner shell 12 provides a sliding space for the pin 13, allowing it to smoothly insert into the circular hole 16 on the adjusting column 2. The pin 13 is used to fix the adjusting column 2 to the hollow column 3. By inserting the pin 13 into different circular holes 16, the height of the scraper 4 can be adjusted. The spring 14 prevents the pin 13 from moving without external force. The locking assembly locks the pin 13 after it is pulled out, eliminating the need to continuously pull on the pin 13.

[0025] Reference Figure 1 - Figure 5The mixing assembly includes a mixer 5, with at least two supports 6 fixedly connected to the outside of the mixer 5. A discharge pipe 17 is fixedly connected to the bottom of the mixer 5. A support block 21 is fixedly connected to the bottom of the mixer 5 via at least two fixed brackets 19. A drive assembly is installed inside the support block 21. A rotating shaft 25 is rotatably connected to the output end of the drive assembly. A slide rail 27 is fixedly connected to the top of the support block 21. A slider 20 is slidably connected to the top of the slide rail 27. One end of the rotating shaft 25 is rotatably connected to the outside of the slider 20. A rubber plate 18 is fixedly connected to the outside of the slider 20 via a connecting rod 26. The rubber plate 18 abuts against the surface of the discharge pipe 17. A handle 8 is fixedly connected to the top of the adjusting column 2. The drive assembly includes a motor 22. A disc 23 is fixedly connected to the output end of the motor 22. An eccentric shaft 24 is fixedly connected to the top of the disc 23. The end of the rotating shaft 25 away from the slider 20 is rotatably connected to the outside of the eccentric shaft 24. The mixer 5 is used to thoroughly mix various materials, which are then placed on the sintering trolley 7 and finally sent into the sintering furnace 1. The bracket 6 supports the entire mixer 5. The fixing bracket 19 fixes the support block 21 to the bottom of the mixer 5. The support block 21 supports the various parts, enabling them to operate normally. The motor 22 drives the disc 23 to rotate, which in turn rotates the eccentric shaft 24. During rotation, the eccentric shaft 24 is rotatably connected to the slider 20 via the rotating shaft 25. Therefore, the slider 20 repeatedly reciprocates on the slide rail 27, causing the rubber plate 18 to repeatedly impact the discharge pipe 17. Due to the rubber material of the rubber plate 18, it does not damage the discharge pipe 17 upon impact. The connecting rod 26 fixes the rubber plate 18 to the slider 20. The handle 8 facilitates the sliding of the adjusting column 2 inside the hollow column 3. The discharge pipe 17 is used to open the valve after the material is uniformly mixed, allowing the material to fall onto the sintering trolley 7.

[0026] Reference Figure 2 and Figure 3 The locking assembly includes a pad 15, which is fixedly connected to the outside of the pin 13. A locking block 9 is fixedly connected to the outside of the pad 15. A U-shaped groove 11 is provided on the outside of the inner shell 12. The locking block 9 is slidably connected inside the U-shaped groove 11. One end of the spring 14 is fixedly connected to one side of the pad 15, and the other end of the spring 14 abuts against the inner wall of the inner shell 12. The pad 15 is used to fix the locking block 9 and transmit the elastic force of the spring 14 to the pin 13. The locking block 9 is used to cooperate with the U-shaped groove 11. When the pin 13 is pulled out from the circular hole 16, the locking block 9 can be locked inside the U-shaped groove 11 by rotating the pin 13, thereby temporarily locking the pin 13 without having to pull the pin 13 continuously, which facilitates the adjustment of the adjusting column 2.

[0027] Reference Figure 1 - Figure 5The transport components include more than one sintering trolley 7, which is located in the middle of the sintering furnace 1 and directly below the discharge pipe 17. The sintering trolley 7 is used to feed materials into the sintering furnace 1 for sintering.

[0028] Working principle: When sintering materials, first pull the pin 13 to pull it out of the circular hole 16 on the adjusting column 2. Then rotate the pin 13 to make the locking block 9 lock inside the U-shaped groove 11, thus temporarily locking the pin 13. It is not necessary to pull the pin 13 with force all the time. At this time, the adjusting column 2 can slide freely inside the hollow column 3, so the height of the scraper 4 can be adjusted. When the adjusting column 2 is slid to the appropriate position, pull the pin 13 slightly to make the pin 13 rotate. Then rotate the pin 13 in the opposite direction to make the locking block 9 slide inside the U-shaped groove 11. Finally, release the pin 13. Under the action of the spring 14, the pin 13 will be inserted into the corresponding circular hole 16 in the adjusting column 2. At this time, when the material on the sintering trolley 7 is about to enter the sintering furnace 1, the scraper 4 will contact the material and spread the material evenly on the sintering trolley 7.

[0029] Before the materials are fed into the sintering trolley 7, various materials are first put into the mixer 5 for uniform mixing. When the mixing is completed, the valve on the discharge pipe 17 is opened. At the same time, the motor 22 starts to work, driving the disc 23 to rotate. Under the action of the eccentric shaft 24 and the rotating shaft 25, as the disc 23 rotates, the slider 20 will slide back and forth on the slide rail 27. Therefore, the rubber plate 18 fixed on the slider 20 will repeatedly hit the discharge pipe 17, thereby speeding up the flow of materials and preventing materials from being blocked inside the discharge pipe 17.

[0030] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
