Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting technology, specifically to a cylindrical mixer liner and the cylindrical mixer thereof. Background Technology

[0002] Sinter is a man-made rich ore with lower costs. Using man-made rich ores (sinter and pellets) in blast furnaces can increase output, reduce fuel consumption, make rational use of resources, and save production costs. With the continuous increase in the clinker ratio in blast furnaces of ironmaking plants, the demand for sinter output is also increasing. Therefore, improving sintering operation rate and reducing accidents has become increasingly important.

[0003] The importance of the cylindrical mixer as the main equipment for sintering, mixing, and granulation is self-evident. Liner detachment accidents in cylindrical mixers are one of the main reasons affecting sintering efficiency. Improper selection or fixing methods of the liners may cause the following problems:

[0004] 1. Poor material discharge, sometimes even material is poured out from the feed inlet.

[0005] 2. The mixer has serious material sticking inside, resulting in high load and vibration, and a large amount of work for maintenance and material removal.

[0006] 3. Wear and corrosion of fixing bolts and insecure fixing of liner plates. If not detected and dealt with in time, large pieces of liner plates or channel steel used to fix the liner plates may fall off, which will block the funnel, scratch the belt, and cause serious production accidents.

[0007] 4. The liners of the cylindrical mixer are prone to wear, requiring frequent replacement and incurring high costs.

[0008] In view of the current state of the technology, there is an urgent need to design a new liner suitable for cylindrical mixers to solve the above-mentioned defects. Utility Model Content

[0009] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a cylindrical mixer liner and a cylindrical mixer thereof.

[0010] According to the present invention, a cylindrical mixer liner includes multiple liner assemblies, which are evenly spaced along the circumferential direction of the inner surface of the cylindrical mixer.

[0011] Each of the liner assemblies includes multiple plates, and the multiple plates in each liner assembly are arranged sequentially at intervals along the axial direction of the cylindrical mixer;

[0012] Each of the plates extends along the axial direction of the cylindrical mixer, and the plates are perpendicular to the inner surface of the cylindrical mixer;

[0013] The plate is made of flat steel and welded to the inner surface of the cylindrical mixer.

[0014] Preferably, the length of the plate is 0.3 to 0.6 m.

[0015] Preferably, the spacing between any two adjacent liner assemblies is 20 to 40 cm.

[0016] Preferably, the plate has a rectangular structure.

[0017] Preferably, reinforcing ribs are provided on one or both sides of the plate.

[0018] Preferably, the reinforcing rib has a triangular structure.

[0019] Preferably, the reinforcing ribs are welded to the inner surfaces of the plate and the cylindrical mixer.

[0020] Preferably, the plate body and the inner surface of the cylindrical mixer have multiple spaced welding areas.

[0021] Preferably, each of the welding areas has a plurality of weld points arranged at intervals.

[0022] According to the present invention, a cylindrical mixer is provided, and the cylindrical mixer liner is used.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This invention eliminates the nylon or polymer liner structures used in the middle and rear sections of existing mixers, instead employing a simple mixer liner made of flat steel. Flat steel and other raw materials are low-cost and cost-effective. The welding method ensures a more secure fixation, and the replacement and maintenance of the flat steel liner after wear is simpler. The vertically arranged plates inside the cylinder reduce material adhesion inside the mixer, ensure smooth discharge, reduce the mixer load, and minimize maintenance and material removal work. Furthermore, the liner in this invention has no large structural components, reducing the risk of material blockage and belt scratches, making it suitable for widespread use.

[0026] Figure 1 This is a schematic diagram of the structure of the plate body in this utility model;

[0031] Welding area 12

[0032] Feed end 2

[0033] Discharge end 3 Detailed Implementation

[0034] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0035] This utility model provides a cylindrical mixer liner, including multiple liner assemblies. The multiple liner assemblies are evenly spaced along the circumference of the inner surface of the cylindrical mixer. The distance between each two adjacent liner assemblies is 20 to 40 cm. The specific distance value is reasonably arranged according to the outer diameter of the cylindrical mixer.

[0036] Each liner assembly includes multiple plates 1, which are arranged sequentially at intervals along a straight line. There are gaps between adjacent plates 1. Connecting plates 1 ensures that if one plate 1 falls, it will cause other plates 1 to fall as well. This arrangement also prevents stress concentration and thermal deformation. Figure 2 As shown, the cylindrical mixer has a feed end 2 and a discharge end 3. Each plate 1 extends along the axial direction of the cylindrical mixer, that is, the length direction of the plate 1 is the same as the direction of material movement.

[0037] Specifically, plate 1 is made of flat steel and has a rectangular structure. Plate 1 is arranged perpendicular to the inner surface of the cylindrical mixer inside the cylindrical mixer. To increase the firmness of plate 1, plate 1 is welded to the inner surface of the cylindrical mixer. Welding is more reliable than fixing with bolts.

[0038] Furthermore, the flat steel inside the cylinder of the cylindrical mixer will stick to the material during the production process, which serves to protect the cylinder. Since the flat steel is relatively narrow, it will not cause serious material sticking, and there is less material sticking than with traditional liners.

[0039] Specifically, the length of plate 1 is 0.3–0.6 m, for example, 0.4 m or 0.5 m. The flat steel inside the cylinder is cut to a length of about 0.4 meters, which is relatively short. During production, the flat steel will wear down and become narrower, and it is also easily bent and deformed. Even if it falls off during production, it is unlikely to cause blockage in the funnel or damage the conveyor belt. Furthermore, most mixing systems have metal picks in multiple locations, which can easily remove metal parts such as flat steel. However, the nylon and polymer liners used in existing technologies cannot remove these parts, which can easily cause many problems in subsequent processes.

[0040] like Figure 1 As shown, reinforcing ribs 11 are provided on one or both sides of the plate 1. The reinforcing ribs 11 are preferably triangular in structure. The reinforcing ribs 11 are preferably welded to the inner surface of the plate 1 and the cylindrical mixer, so that the plate 1 is more firmly fixed.

[0041] Flat steel lining plates are welded inside the cylinder. The flat steel is perpendicular to the inner surface of the cylinder. The lower side of the flat steel is fixed to the cylinder by intermittent welding. Specifically, there are multiple welded areas 12 arranged at intervals between the plate 1 and the inner surface of the cylindrical mixer. Each welded area 12 has multiple weld points arranged at intervals to avoid stress concentration caused by full welding.

[0042] This utility model also provides a cylindrical mixer, which uses the cylindrical mixer liner plate described above in this utility model.

[0043] This utility model uses a mixer liner made of flat steel, which has the following advantages:

[0044] 1. The raw materials such as flat steel have low cost, the lining plate has low cost, and the cost performance is high.

[0045] 2. The mixer has less material sticking inside, smooth discharge, low load, and requires less maintenance and material removal work.

[0046] 3. Wear was found on the flat steel liner, and replacement and maintenance are simple.

[0047] 4. The liner plate has no large structural components, minimizing the risk of material blockage and belt scratches. It can be widely used.

[0048] This invention can be made from locally available materials, using flat steel, is easy to install, has a low failure rate, is highly portable, requires no special tools or auxiliary equipment, and is suitable for sintering mixers under different working conditions.
