Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln turnover structure. Background Art

[0002] A rotary kiln is a type of equipment used to produce cement and other ore materials. It is usually a long, round, cylindrical structure that rotates to process raw materials at high temperatures. A rotary kiln is usually made of steel and lined with refractory materials to withstand high temperatures and chemical corrosion. Raw materials enter through a port in the rotary kiln and are then processed by rotation at high temperatures to produce cement or other ore products. The rotary kiln plays a vital role in cement production, processing raw materials efficiently and ensuring the quality and stability of the final product.

[0003] Usually, there are many spirally arranged lining plates inside the rotary kiln to avoid the situation that the material is not calcined thoroughly when it is too thick. However, most traditional lining plates are welded to the inner wall of the rotary kiln cylinder. If damaged, it is very inconvenient to repair. Moreover, if some small particle materials are processed, it is easy to cause adhesion on the lining plate and the inner wall of the cylinder after long-term use, and it is very inconvenient to clean, which can easily affect the normal operation of the rotary kiln. Utility Model Content

[0004] The present application provides a rotary kiln turnover structure, which can solve the problem that the liner in the existing rotary kiln is inconvenient to repair and the problem that the liner and the inner wall of the cylinder are difficult to clean due to adhesion.

[0005] In the present application, a rotary kiln flip structure is provided, comprising a cylinder, on which an external gear is arranged, and characterized in that: the cylinder is split into two half cylinders along its axial surface, and the external gear is also split into two half gears, one end of the two half cylinders is hinged, and the other end is detachably connected, when the two half cylinders are connected together, the two half cylinders are combined into the cylinder, and the two half gears are combined into the external gear; a plurality of lining plates, each of which is fixedly provided with a mounting plate at the lower end, and the mounting plate is detachably connected to the inner wall of the cylinder by a threaded connection.

[0006] In one embodiment, a first connecting plate is provided at one end of the two half-cylinders opposite to the hinge, and the first connecting plate on one of the half-cylinders is detachably connected to the first connecting plate on the other half-cylinder by means of a threaded connection.

[0007] In one embodiment, a plurality of the first connecting plates are provided on each of the half cylinders.

[0008] In one embodiment, it further includes a second connecting plate, which is detachably connected between the two half-cylinders by means of a threaded connection.

[0009] In one embodiment, both upper and lower side surfaces of the mounting plate are inclined to the radial direction of the cylinder.

[0010] In one embodiment, the first connecting plate and the second connecting plate are both made of steel.

[0011] In summary, in the present application, a rotary kiln flipping structure has the following beneficial effects compared with the prior art: during normal operation, the two half-cylinders and the two half-gears are combined together; when adhesion occurs on the lining plate and the inner wall of the cylinder, the two half-cylinders and the two half-gears can be opened to clean the lining plate or the inner wall of the cylinder, which is relatively simple and convenient; when the lining plate is damaged, it can be removed through the mounting plate for repair, or directly replaced with a new one, which is simple and convenient, can avoid long-term adhesion as much as possible, and improves the production and processing quality.

[0019] See also Figure 1 In one embodiment, a rotary kiln flip structure includes a cylinder 1 and a plurality of lining plates 5. The cylinder 1 is split into two half cylinders 2 along its axial surface. A circle of external gears 7 is arranged in the middle of the cylinder 1. The external gear 7 is also split into two half gears 8. One end of the two half cylinders 2 is hinged and the other end is detachably connected. When the two half cylinders 2 are connected together, the two half cylinders 2 are combined into the cylinder 1, and the two half gears 8 are combined into the external gear 7.

[0020] See also Figure 1 , Figure 3 In one embodiment, the ends of the two half-tubes 2 opposite to the hinged joint are both extended outwards and fixed with a first connecting plate 3, and the first connecting plate 3 on one of the half-tubes 2 and the first connecting plate 3 on the other half-tube 2 are detachably connected by threaded connection, specifically: a first through hole is provided on one of the half-tubes 2, and a first threaded hole is provided on the other half-tube 2, and the position of each first through hole corresponds to a first threaded hole, and a first bolt 9 and a first nut 10 are provided, and the first bolt 9 can pass through the first through hole and the first threaded hole to connect with the first nut 10. With this arrangement, the structure is easy to implement and the operation is relatively simple.

[0021] See also Figure 1 In one embodiment, a plurality of the first connecting plates 3 are fixedly arranged in a transverse direction on each of the half cylinders 2, except for the outer gear 7. This arrangement provides a better connection effect and higher stability.

[0022] See also Figure 1In one embodiment, it further includes a second connecting plate 4, which is detachably connected between the two half-cylinders 2 by means of a threaded connection. The second connecting plate 4 can be covered in a place between the two half-cylinders 2 where the first connecting plate 3 is not provided. When the second connecting plate 4 is connected between the two half-cylinders 2, it fits with the outer walls of the two half-cylinders 2. Furthermore, each of the half-cylinders 2 is provided with a second threaded hole, and the second connecting plate 4 is provided with a second through hole, and a second screw 11 is provided which can pass through the second through hole and be screwed into the second threaded hole. This arrangement further improves the stability of the working connection between the two half-cylinders 2. In one embodiment, preferably, the first connecting plate 3 and the second connecting plate 4 are both made of steel. This arrangement is because the structural strength of steel is relatively high and relatively stable.

[0023] See also Figure 2 , Figure 3 , a mounting plate 6 is fixedly provided at the lower end of each liner 5 by welding or integral molding, and the mounting plate 6 is detachably connected to the inner wall of the cylinder 1 by threaded connection, so as to realize the detachability of the liner 5 on the cylinder 1. A third through hole is provided on the mounting plate 6, a third threaded hole is provided on the inner wall of the cylinder 1, and a third screw 12 is provided which can pass through the third through hole and be screwed into the third threaded hole. Preferably, four third screws 12 are provided on each mounting plate 6. In one embodiment, the upper and lower side surfaces of the mounting plate 6 are inclined to the radial direction of the cylinder 1. Such a configuration can minimize the possibility that the material is stuck on the side of the liner 5 when rolling on the inner wall of the cylinder 1 during operation.

[0024] Working principle: During normal operation, the two half-cylinders 2 and the two half-gears 8 are put together; when adhesion occurs on the lining plate 5 and the inner wall of the cylinder 1, the two half-cylinders 2 and the two half-gears 8 can be opened, and the lining plate 5 or the inner wall of the cylinder 1 can be cleaned, which is relatively simple and convenient; when the lining plate 5 is damaged, it can be removed through the mounting plate 6 for repair, or directly replaced with a new one.
