Description

Technical Field

[0001] This utility model relates to the field of stepped grates, and more specifically, to a stepped grate structure with anti-clogging function. Background Technology

[0002] The stepped grate is a key component in cement production. It consists of multiple grate units with different heights arranged in a stepped manner. They are mostly made of heat-resistant steel by casting or welding. Its stepped structure can guide the clinker to flow evenly, enhance ventilation and heat exchange, and improve conveying efficiency.

[0003] In the prior art, since the ventilation holes are generally located below the grate, and there is a gap between the two grates, the airflow direction can easily be changed, which can cause the clinker to roll. The gaps on the grate are usually fixed, which makes it difficult to adapt to different clinkers. At the same time, the fixed gaps can easily get stuck in the gaps when the clinker falls, which can cause blockage and make it difficult for air to circulate. In view of this, we propose a stepped grate structure with anti-blockage function. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the current gap is usually fixed and difficult to adapt to different clinker.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a stepped grate structure with anti-clogging function, comprising a mounting box. A grate is fixedly connected to the inner wall of the mounting box, and multiple sets of grate are provided. Each grate has a through groove, and the multiple sets of grate are arranged in a stepped manner. An electric push rod is fixedly connected to the rear inner wall of the mounting box, and a push plate is fixedly connected to the output end of the electric push rod. Two mounting plates are slidably connected to the inner wall of the mounting box, and the push plate is fixedly connected between the two mounting plates. A first guide plate is fixedly connected between the two mounting plates, and the first guide plate is obliquely arranged. The lower surface of the first guide plate is fixedly connected to the upper surface of the push plate. An adjusting plate is fixedly connected between the two mounting plates, and the adjusting plate is stepped. An adjusting groove is provided on the upper surface of the adjusting plate, and the adjusting groove communicates with the through groove on the grate. An auxiliary component is provided on the mounting box.

[0006] As a preferred technical solution of this application, the auxiliary component includes two air outlet plates, which are respectively fixedly connected to the inner walls of the left and right sides of the mounting box.

[0007] As a preferred technical solution of this application, sliding grooves are provided on the inner walls of both the left and right sides of the mounting box, and two vertical plates are fixedly connected to the lower surface of the adjusting plate.

[0008] As a preferred technical solution of this application, sliding blocks are fixedly connected to the surfaces of the two vertical plates that are far apart from each other, and the sliding blocks extend into the interior of the sliding groove.

[0009] As a preferred technical solution of this application, the sliding block is slidably connected to the sliding groove, and anti-blocking plates are fixedly connected to the inner walls of the left and right sides of the mounting box.

[0010] As a preferred technical solution of this application, the anti-blocking plate is inclined.

[0011] As a preferred technical solution of this application, a high-pressure air outlet is fixedly connected to the lower inclined surface of the anti-blocking plate, and a second guide plate is fixedly connected to the inner wall of the mounting box, with the lower surface of the second guide plate in contact with the upper surface of the final measuring grate plate.

[0012] As a preferred technical solution of this application, the right side surface of the adjusting plate vertical plate is provided with a relief groove extending out of its left side surface, and an extension plate is fixedly connected to the upper side surface of the grate plate, the extension plate being adapted to the relief groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. By setting the adjustment plate and adjustment groove, the spacing of the through grooves on the grate can be adjusted at any time to adapt to clinker of the same size. The stepped adjustment plate can also close the gap between multiple sets of grates to prevent the clinker from rolling forward due to wind blowing out through the gap.

[0016] 2. The extension plate can compensate for the gap between the adjusting plate and the grate after the adjustment plate moves, preventing clinker from entering the gap and causing blockage during subsequent reset. At the same time, when the air outlet plate is blocked, the high-pressure air outlet can be used to clean the air outlet plate. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A stepped grate structure with anti-clogging function includes a mounting box 1. A grate 2 is fixedly connected to the inner wall of the mounting box 1. Multiple sets of grate 2 are provided, and through slots 16 are formed on each grate 2. The multiple sets of grate 2 are arranged in a stepped manner. An electric push rod 3 is fixedly connected to the rear inner wall of the mounting box 1. A push plate 4 is fixedly connected to the output end of the electric push rod 3. Two mounting plates 5 are slidably connected to the inner wall of the mounting box 1. The push plate 4 is fixedly connected between the two mounting plates 5. A first guide plate 6 is fixedly connected between the two mounting plates 5. The first guide plate 6 is obliquely arranged, and the lower side of the first guide plate 6... The surface is fixedly connected to the upper surface of the push plate 4, and an adjustment plate 7 is fixedly connected between the two mounting plates 5. The adjustment plate 7 is set in a stepped shape, and an adjustment groove 8 is opened on the upper surface of the adjustment plate 7. The adjustment groove 8 communicates with the through groove 16 on the grate plate 2. An auxiliary component is set on the mounting box 1. Through the setting of the adjustment plate 7 and the adjustment groove 8, the spacing of the through groove 16 on the grate plate 2 can be adjusted at any time to adapt to clinker of the same size. The stepped adjustment plate 7 can also close the gap between multiple sets of grate plates 2 to prevent the clinker from rolling forward due to the wind blowing out through the gap.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the auxiliary components include two air outlet plates 9, which are fixedly connected to the inner walls of the left and right sides of the mounting box 1. Sliding grooves 10 are provided on the inner walls of both sides of the mounting box 1. Two vertical plates 11 are fixedly connected to the lower surface of the adjusting plate 7. Sliding blocks 12 are fixedly connected to the surfaces of the two vertical plates 11 that are far apart from each other. The sliding blocks 12 extend into the interior of the sliding grooves 10 and are slidably connected to the sliding grooves 10. Anti-blocking plates 13 are fixedly connected to the inner walls of both sides of the mounting box 1. The anti-blocking plates 13 are inclined, and a high-pressure air outlet 1 is fixedly connected to the inclined surface of the lower side of the anti-blocking plate 13. 4. A second guide plate 15 is fixedly connected to the inner wall of the mounting box 1. The lower surface of the second guide plate 15 contacts the upper surface of the last grate plate 2. A clearance groove 17 extending from the left surface of the right side of the vertical plate of the adjusting plate 7 is provided. An extension plate 18 is fixedly connected to the upper surface of the grate plate 2. The extension plate 18 is adapted to the clearance groove 17. The extension plate 18 can make up the gap between the adjusting plate 7 and the grate plate 2 after the movement, so as to avoid the clinker entering the gap and causing blockage during subsequent reset. At the same time, when the air outlet plate 9 is blocked, the high-pressure air outlet head 14 can be used to clean the air outlet plate 9.

[0030] The length of the sliding block 12 only occupies a part of the sliding groove 10. If the clinker enters the interior of the sliding groove 10, it will not affect the movement of the sliding block 12. The clinker will be pushed away by the sliding block 12 and will not get stuck.

[0031] The usage process of the stepped grate structure with anti-clogging function provided by this utility model is as follows:

[0032] When adjusting the width of the through groove 16 of the grate plate 2, the push plate 4 can be moved by the electric push rod 3. When the push plate 4 moves, it will drive the mounting plate 5 and the first guide plate 6 to move simultaneously. After the first guide plate 6 moves, it will move out of the lower side of the second guide plate 15, thereby extending the guide length of the clinker. Since the grate plate 2 is fixedly connected to the inner wall of the mounting box 1, when the mounting plate 5 moves, it will drive the adjusting plate 7 to move simultaneously. When the adjusting plate 7 moves, the adjusting groove 8 and the through groove 16 will be staggered, thereby reducing the width through which the through groove 16 can pass and completing the angle adjustment of the through groove 16. At the same time, the extension plate 18 is used to fill the gap between the adjusting plate 7 and the grate plate 2 after the movement, so as to prevent the clinker from entering the gap and causing blockage during subsequent reset. The stepped adjusting plate 7 can fill the gap between multiple sets of grate plates 2, preventing the air from blowing out through the gap between the grate plates 2 and causing the clinker to roll forward. At the same time, when the air outlet plate 9 is blocked, the high-pressure air outlet head 14 can be used to clean the air outlet plate 9.
