Description

Technical Field

[0001] The utility model relates to a modular assembled cooling kiln, belonging to the technical field of cooling kilns. Background Art

[0002] In the non-ferrous metal smelting and metallized pellet cooling process links of enterprises such as chemical plants and steel plants that require material cooling, after the ore powder and ore raw materials extract the required ore elements by burning in a rotary kiln furnace, there will be a large amount of remaining ore slag and other materials that need to be cooled. Generally, it is necessary to configure a chemical plant coke cooler, a non-ferrous metal smelting kiln slag cooling kiln, a steel plant steel slag cooling kiln, a steel plant pellet cooling kiln, etc.

[0003] The existing cooling kiln is an external spray cylinder structure. High-temperature materials at about 1100 °C are loaded into the cylinder, and cooling water is sprayed on the surface of the cylinder. The temperature of the high-temperature materials inside the cylinder is reduced through the heat exchange between the cold water and the cylinder. This kind of cooling kiln is simple and easy to operate. However, during the cooling process, most of the water forms water vapor and is directly discharged into the atmosphere without organization, resulting in white pollution and having an adverse impact on the environment. At the same time, the heat carried away by the evaporated water and the high-temperature pellets is also wasted, and the equipment is severely corroded by oxidation due to long-term water erosion.

[0004] Chinese Patent with publication number CN217818293U discloses a drum cooling kiln. By setting a three-layer heat exchange tube structure, the indirect contact area between the high-temperature gasification furnace slag and the cooling water is greatly increased, and the indirect contact time between the material and the cooling water is extended. However, for some cooling kilns in the prior art, the size is very large, the maximum length can reach 50 - 60 meters, and the maximum diameter is 7 - 8 meters. They cannot be transported over long distances, and need to be replaced as a whole after being damaged, resulting in relatively high maintenance costs.

[0005] In summary, it is obvious that there are inconveniences and defects in the prior art in actual use, so it is necessary to make improvements. Content of the Utility Model

[0006] Aiming at the deficiencies in the background art, the utility model provides a modular assembled cooling kiln, which is assembled by multiple modules, facilitating disassembly and assembly, and also facilitating long-distance transportation.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A modular assembled cooling kiln includes a plurality of arc-shaped water-cooled wall modules, and the plurality of water-cooled wall modules enclose a water-cooled wall cylinder;

[0009] A plurality of water-cooled wall cylinders are horizontally connected to form a cooling kiln, and cooling water pipes are provided on the water-cooled wall modules to cool the materials in the cooling kiln.

[0010] Further, a water wall cylinder comprises six water wall modules.

[0011] Further, multiple cooling water pipes are arranged horizontally on the outer side of the water wall module.

[0012] Further, the cross-section of the cooling water pipe is semi-circular, and the semi-circular side wall of the cooling water pipe faces the outer side of the water wall module.

[0013] Further, a horizontal reinforcing rib plate is arranged horizontally at the middle position of the outer wall of the water wall module.

[0014] Further, the water wall module includes end water pipes arranged at both ends thereof, and the end water pipes are communicated with multiple cooling water pipes.

[0015] Further, end water inlets are arranged at both ends of the end water pipe; side water inlets are arranged on the outer side surface of the end water pipe.

[0016] Further, a plurality of longitudinal bolt connection pairs are respectively arranged on both side surfaces of the water wall module, and multiple water wall modules are spliced into a water wall cylinder through the longitudinal bolt connection pairs.

[0017] Further, a plurality of horizontal bolt connection pairs are respectively arranged on both end surfaces of the water wall module, and multiple water wall cylinders are spliced into a cooling kiln through the horizontal bolt connection pairs.

[0018] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0019] The cooling kiln is assembled in a split modular manner and includes a plurality of arc-shaped water wall modules. The plurality of water wall modules enclose a water wall cylinder, and the plurality of water wall cylinders are horizontally connected to form a cooling kiln. Cooling water pipes are arranged on the water wall modules to cool the materials in the cooling kiln; when the size of the cooling kiln is large, the scattered water wall modules can be transported to the site for on-site assembly, so it is convenient for long-distance transportation. When a certain module is damaged, it can be replaced separately, so it is convenient for disassembly and maintenance.

[0028] As Figure 1 shown, the present utility model provides a modular - assembled cooling kiln, which includes a plurality of arc - shaped water - cooled wall modules A. A plurality of water - cooled wall modules A enclose a water - cooled wall cylinder. According to the size of the diameter of the cooling kiln, a water - cooled wall cylinder can be composed of 2 to 8 water - cooled wall modules A (preferably six).

[0034] The water - cooled wall module A includes end water delivery pipes 4 arranged at both ends thereof, as Figure 3 and Figure 4 shown. The end water delivery pipes 4 are communicated with a plurality of cooling water pipes 5. Cooling water enters the cooling water pipes 5 from the end water delivery pipe 4 at one end, and then flows out from the end water delivery pipe 4 at the other end to form a water circulation loop.

[0035] On both sides of the water wall module A, a plurality of longitudinal bolt connection pairs 2 are respectively provided. Through the longitudinal bolt connection pairs 2, a plurality of water wall modules A are spliced into a water wall cylinder; on both end faces of the water wall module A, a plurality of transverse bolt connection pairs 3 are respectively provided.
