Description

Technical Field

[0001] The present application relates to the technical field of grate coolers, and in particular to a snowman pushing device and a grate cooler. Background Art

[0002] Snowman phenomenon is a common phenomenon in most rotary kilns. It is easy to form "snowman" on the fixed grate plate at the feed end of the grate cooler. If it is not handled in time or in an incorrect way, it is easy to cause the "snowman" to grow bigger and bigger, and even block the kiln mouth. At present, the conventional practice is to arrange multiple air cannons at an appropriate height around the front shell of the feed end of the grate cooler, fire them at the right time, clean up the excessive red-hot clinker and early "snowman", and avoid the formation of "snowman" to a certain extent.

[0003] However, in some special cases, such as some parts cannot be equipped with air cannons due to space limitations, and due to untimely cleaning or air cannon failure, the early "snowman" has the conditions to take root in some parts, and the lower part of the "snowman" has hardened, making it difficult to clean with air cannons. In addition, due to the diversity of material components, it is very easy to produce liquid phase melting and accumulation on the fixed grate bed.

[0004] In the related technology, some use mechanical cleaning to remove snowmen, but due to the air-cooled structure of the grate bed, which includes a fixed stepped grate bed structure, in actual use, the bottom of the fixed grate bed is difficult to be cleaned thoroughly. As time goes on, once the snowmen in this area harden and take root, the growth rate of the snowmen in the entire grate cooler will accelerate. Summary of the invention

[0025] The snowman pushing device of the present application is applied to the grate cooler. Since the grate bed of the grate cooler has an air-cooled structure, it is usually a stepped structure. Therefore, even if the method of cleaning the snowman is mechanical, such as using a push plate to push the snowman. However, there is a dead angle between the push plate and the grate plate of the stepped fixed grate bed 82. In order to ensure the sealing between the push plate and the housing 81 of the grate cooler and prevent the leakage of high-temperature materials, the push plate and the housing 81 of the grate cooler are sealed, that is, the push plate can only move in a straight line; therefore, the snowman in this dead angle is difficult to be cleaned, and as time goes on, the snowman in this position takes root, causing the snowman in the entire grate cooler to grow rapidly.

[0026] To this end, the present application embodiment discloses a snowman pushing device. Figure 1 and Figure 2 A snowman pushing device, a grate cooler includes a fixed grate bed 82 in a stepped shape, and the device includes: a bracket 1, a material pushing box body 2, a power component 3 and a cleaning component 4 (see Figure 4 ).

[0027] Reference Figure 1 The support 1 is arranged at one side of the feeding end of the grate cooler, the pusher box 2 is slidably arranged on the support 1, and a support is arranged at the bottom of the support 1. Two or more supports can be overlapped and arranged according to the actual use height. The pusher box 2 is slidably arranged in the front housing 81 of the grate cooler and can extend into the grate cooler.

[0028] Reference Figure 2 and Figure 3The material pushing box body 2 is a box-shaped structure as a whole. The front end of the material pushing box body 2 is a front end plate 23. The front end plate 23 is made of heat-resistant material. In some embodiments, the front end plate 23 can be made of 2520 heat-resistant steel, and the heat-resistant temperature can reach 1350 degrees to ensure that the front end does not deform during operation. In some embodiments, the front end plate 23 can be set vertically, that is, the front end plate 23 is perpendicular to the length direction of the material pushing box body 2; in other embodiments, the front end plate 23 can be set downwardly tilted, and the front end plate 23 can be a flat plate or a curved plate.

[0029] Further, see Figure 3 A first partition plate 21 is provided in the pushing box body 2, and a first heat-insulating cavity 22 is formed between the first partition plate 21 and the front end plate 23. Heat-insulating material is provided in the first heat-insulating cavity 22. A pouring hole for pouring castable is reserved in the front end plate 23. In some embodiments, refractory castable can be poured into the first heat-insulating cavity 22 through the pouring hole to further improve the heat-resistant performance and prevent the pushing box body 2 from deformation.

[0030] Reference Figure 2 There is a gap between the bottom of the push box 2 and the top of the fixed grate bed 82, and the size of the gap is 2-3mm, so that the push box 2 can move smoothly and prevent interference with the fixed grate bed 82 due to deformation. Further, the push box 2 is tilted, and the angle between the push box 2 and the fixed grate bed 82 is 12 0 -16 0 . On the one hand, in the process of cleaning the snowmen inside the grate cooler, the more parallel the pusher box body 2 and the upper cut surface of the fixed grate bed 82 are, the better the effect of cleaning the snowmen at the bottom layer. Because the snowmen at the bottom layer, that is, the snowmen closer to the fixed grate bed 82, are harder, the more difficult it is to clean them. If the pusher box body 2 does not directly contact the snowmen there, it is difficult for the upper snowmen to move and drive the lower snowmen to move. On the other hand, in the process of the forward movement of the inference box body, the farther the movement stroke, the more snowmen are cleaned, so the height of the snowman at the front end of the pusher box body 2 is higher; and in order to control the size of the opening of the grate cooler for the pusher box body 2 to pass through, the height of the pusher box body 2 is limited. Therefore, when the height of the snowman is too high, the snowman is easy to collapse backwards, and it needs to be cleaned back and forth many times, which reduces the cleaning efficiency; and prolongs the working time of the pusher box body 2 inside the grate cooler, and even causes the pusher box body 2 to deform. Therefore, in the present application, the angle between the push box body 2 and the fixed grate bed 82 is set to 120-160, which is the angle between the bottom surface of the push box body 2 and the connecting surface between the multiple fixed grate plates. The push box body 2 and the fixed grate bed 82 tend to be parallel, and the front end of the push box body 2 is as close to the fixed grate plate as possible to improve the cleaning effect of the snowman on the bottom layer; and because of a certain angle, when the push box body 2 moves to the far end, that is, away from the end of the bracket 1, the push box body 2 can be relatively close to the middle position of the snowman, preventing the snowman from collapsing and improving the cleaning efficiency.

[0031] Reference Figure 1 and Figure 2 The power assembly 3 is connected to the material pushing box body 2 and is used to drive the material pushing box body 2 to move. In this embodiment, the power assembly 3 is set as a cylinder. In other embodiments, the power assembly 3 can also be set as a cylinder, an electric cylinder or other linear driving mechanism. In order to ensure the smooth movement of the material pushing box body 2, two cylinders are arranged in parallel. The cylinders are hinged on the bracket 1, and the piston rods of the cylinders are hinged to the material pushing box body 2.

The elastic member 61 is arranged on the moving seat 41 to drive the lifting rod 5 to move downward. In this embodiment, the elastic member 61 is arranged as a compression spring, and a boss 51 is fixedly arranged on the lifting rod 5. The compression spring is sleeved on the lifting rod 5, and one end of the compression spring abuts against the bottom wall of the moving seat 41, and the other end abuts against the top of the boss 51. In other embodiments, the elastic member 61 can also be an elastic rope or a spring sheet. It can be understood that as long as it can provide a downward force for the lifting rod 5. In the process of cleaning the snowman, if a hard raised part is encountered, the lifting rod 5 can move upward to prevent the raised part from interfering with the movement of the cleaning plate 42.
