Description

Technical Field

[0001] The utility model relates to the field of brick firing, in particular to a coal slag processing device for brick firing. Background Art

[0002] Firing bricks is a core step in brick and tile production. During this process, the bricks, after mixing and forming, are placed in a kiln. High-temperature hot air, typically generated by burning coal, is introduced into the kiln, causing the temperature inside to rise dramatically. Under the influence of high temperatures, the moisture in the bricks evaporates, and the raw materials undergo physical and chemical reactions, gradually solidifying and forming hard bricks. Coal slag, the solid waste produced by the high-temperature combustion of coal, contains unburned carbon particles, ash, and small amounts of minerals. Its effective treatment is crucial for improving resource utilization and reducing environmental pollution.

[0003] At present, the traditional firing process of small and medium-sized bricks mostly uses coal as the heat source. The firing process requires continuous addition of coal, and the continuous combustion of coal continuously produces coal slag. If this coal slag is not handled in time, it will not only take up a lot of space.

[0004] The hot air pipes are heated directly by coal combustion, and the disposal of the slag after coal combustion has become a major problem. Existing treatment methods mostly involve manual cleaning or simple mechanical collection, which is not only inefficient but also labor-intensive. Utility Model Content

[0005] In order to overcome the disadvantage that coal slag is inconvenient to handle, the utility model provides a coal slag collection and treatment device for brick firing.

[0007] In one embodiment, the discharge assembly includes a guide rail, a return spring, a blanking plate, a receiving box, a wedge plate and a collection box. The receiving box is connected to the air duct, and an opening is opened on the top of the receiving box, and the opening is located directly below the inner wall.

The bottom of the guide rail is slidably connected to the blanking plate, and a return spring is connected between the blanking plate and the guide rail. A wedge plate is connected to the receiving box, and the end of the blanking plate is squeezed and fitted with the wedge plate. The internal groove of the receiving box is inclined, and the collection box is slidably connected to the air duct and is located below the lowest end of the receiving box groove. The wedge plate is an isosceles triangle with the top angle facing upward.

[0008] In one embodiment, it also includes a fixing ring, a connecting rod and a scraper. The fixing ring is connected to the inside of the shell. A plurality of connecting rods are connected below the fixing ring. The bottoms of the plurality of connecting rods are commonly connected to the scraper. The scraper is slidably connected to the inner wall.

[0009] In one embodiment, the device further includes a baffle, which is slidably connected to the receiving box and is used to close the opening.

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Embodiment: A device for treating coal slag for firing bricks, such as Figure 1-Figure 5 As shown, it includes an air duct 1, a heating barrel 101, an outer shell 2, an inner wall 3, a mounting block 4, a servo motor 5, a screw 6, a limit rod 601 and a discharging assembly. The heating barrel 101 is installed in the air duct 1, and the bottom of the heating barrel 101 is layered, with an outer shell 2 and an inner wall 3 respectively provided, and the inner wall 3 is slidably connected to the outer shell 2, the outer shell 2 is connected to the mounting block 4, the mounting block 4 is installed with a servo motor 5, the lower end of the servo motor 5 is connected to the screw 6, and the side symmetrical to the screw 6 is connected to the outer shell 2. The limit rod 601 is connected to the inner wall 3, the inner wall 3 is threadedly connected to the screw 6, and is slidably connected to the limit rod 601, and a discharging assembly for guiding the discharging of coal slag is provided at the bottom of the inner wall 3.

[0023] like Figure 3 and Figure 4 As shown, the discharging assembly includes a guide rail 7, a return spring 8, a blanking plate 9, a receiving box 10, a wedge plate 1001 and a collecting box 12. The receiving box 10 is connected to the air duct 1. An opening 11 is opened on the top of the receiving box 10. The opening 11 is located directly below the inner wall 3. Guide rails 7 are connected to both sides of the bottom of the inner wall 3. The bottom of the guide rail 7 is slidably connected to the blanking plate 9. A return spring 8 is connected between the blanking plate 9 and the guide rail 7. A wedge plate 1001 is connected to the receiving box 10. The end of the blanking plate 9 is squeezed and fitted with the wedge plate 1001. The internal through groove of the receiving box 10 is inclined. The collecting box 12 is slidably connected to the air duct 1 and is located below the lowest end of the through groove of the receiving box 10. The wedge plate 1001 is an isosceles triangle with the top angle facing upward.

[0024] After the coal is added, it burns and then forms slag. When it needs to be cleaned, the servo motor 5 is turned on to drive the screw rod 6 to rotate, thereby pushing the inner wall 3 to move downward. At this time, the blanking plate 9 is squeezed with the wedge plate 1001, pushing the blanking plate 9 to slide to both sides, opening the opening 11 at the bottom of the inner wall 3 and compressing the return spring 8 at the same time. The slag immediately falls through the opening 11 and slides along the inclined through groove of the receiving box 10 into the collecting box 12. The servo motor 5 is reversed, the screw rod 6 rotates, and the inner wall 3 slides along the limit rod 601 and also resets upward. The blanking plate 9 slides along the wedge plate 1001. Under the action of the return spring 8, the bottom through hole of the inner wall 3 is closed, and the collecting box 12 is pulled out to deal with the slag.

[0025] like Figure 2 and Figure 3 As shown, it also includes a baffle 16, which is slidably connected to the receiving box 10 and is used to close the opening 11. When it is necessary to clean the coal slag, the baffle 16 is pulled out so that the coal slag can be discharged through the opening 11. During normal operation, the baffle 16 is pushed in and the airflow will not enter the receiving box 10 along the opening 11.

[0026] like Figure 5 As shown, the invention also includes a fixing ring 13, a connecting rod 14 and a scraper 15. The fixing ring 13 is connected to the inside of the shell 2. A plurality of connecting rods 14 are connected below the fixing ring 13. The bottoms of the plurality of connecting rods 14 are commonly connected to the scraper 15. The scraper 15 is slidably connected to the inner wall 3. When the inner wall 3 moves downward, the inner wall 3 and the scraper 15 slide and rub against each other to scrape off the coal slag stuck on them.

[0027] like Figure 2 and Figure 3 As shown, a handle 17 is also included. The handle 17 is connected to the outer end of the collection box 12. It is more convenient to pull out the collection box 12 through the handle 17.

[0028] like Figure 1 As shown, it also includes a transparent protective cover 18, which is connected to the side of the air duct 1, and the baffle 16 is slidably connected to the transparent protective cover 18. The design of the transparent protective cover 18 ensures the smoothness of the baffle 16 during the sliding process, preventing it from colliding with the edge of the receiving box 10 at the opening 11 when pushed in or pulled out.

[0029] like Figure 2 As shown, it also includes an air guide plate 19, which is connected to the side of the receiving box 10. The air guide plate 19 can effectively guide the airflow to pass smoothly, avoiding the airflow directly colliding with the vertical surface of the receiving box 10, thereby optimizing the flow path of the airflow.

[0030] During the brick-firing process, coal burns in the heating barrel 101, and the resulting high-temperature gas circulates through the air duct 1, providing the necessary heat for the bricks. Simultaneously, the coal slag formed after the coal combustion gradually accumulates at the bottom of the heating barrel 101 and around the inner wall 3. At this point, the coal slag is ready for cleaning, the inner wall 3 is in its initial position, and the blanking plate 9 is pressed against the bottom of the inner wall 3 by the action of the return spring 8. When the coal slag needs to be cleaned, the servo motor 5 is started. The servo motor 5 drives the screw 6 to rotate. Since the inner wall 3 is threadedly connected to the screw 6 and guided by the limiting rod 601, the inner wall 3 begins to slowly descend along the direction of the screw 6. During the descent, the blanking plate 9 at the bottom of the inner wall 3 gradually approaches and squeezes the wedge plate 1001. The inclined design of the wedge plate 1001 causes the blanking plate 9 to slide to both sides, thereby opening the channel at the bottom of the inner wall 3. Under the action of gravity, the coal slag falls into the receiving box 10 through the opening 11 and slides along its inclined through groove into the collection box 12. At the same time, the return spring 8 is compressed. After the coal slag is discharged, the servo motor 5 reverses, and the screw 6 rotates in the opposite direction, pushing the inner wall 3 to slide upward and reset along the limit rod 601. As the inner wall 3 rises, the blanking plate 9 slides back to its original position along the inclined surface of the wedge plate 1001 under the action of the return spring 8, re-sealing the through hole at the bottom of the inner wall 3. When the coal slag in the collection box 12 accumulates to a certain amount, it can be easily pulled out of the air duct 1 through the handle 17 for centralized treatment of the coal slag. In addition, as the inner wall 3 moves up and down, the scraper 15 will slide and rub against the surface of the inner wall 3, effectively scraping off the coal slag stuck on it and keeping the inner wall 3 clean.
