Description

Technical Field

[0001] This utility model relates to the field of pellet production equipment technology, and in particular to a novel partition wall for a pellet ring cooler. Background Technology

[0002] In the pelletizing process, the ring cooler is one of the three main components in the chain grate-rotary kiln pellet production. Its main function is to cool the high-temperature pellets discharged from the rotary kiln for safe transportation and storage, while recovering heat from the high-temperature pellets for use in the preceding processes. The operating status of the ring cooler not only directly affects the production capacity of the "chain-rotary-ring" system and the quality of the pellets, but also has a significant impact on the energy consumption and operating costs of the entire system.

[0003] The cooling system of annular coolers is typically divided into four sections, each separated by a partition wall. The original partition walls were air-cooled, box-shaped structures with welded anchors on the surface and a castable refractory outer layer. Because the cooling method relied solely on air cooling, the anchors were prone to oxidation and burning under high temperatures, leading to refractory material detachment, partition wall failure, and reduced cooling efficiency, thus affecting pellet production and quality. Chinese patent (authorization announcement number CN204987893U) discloses an "improved partition wall for a pellet annular cooler," which involves installing multiple baffles on the upper and lower inner walls of the air box. These baffles divide the internal cavity of the air box into several zigzag-shaped air ducts, one end of which connects to the air inlet and the other end to the air outlet. This allows for sufficient heat exchange between the partition wall air box plates and the cooling air, enhancing the cooling effect. However, this cooling method still relies solely on air as the cooling medium, and its cooling effect is not fundamentally improved. Another patent (authorization announcement number CN21016577U) discloses a partition wall for an annular chiller that combines air cooling and water cooling. However, this method, which combines air cooling and water cooling, results in a complex structure, longer maintenance time, and its safety and reliability can be further improved.

[0004] To address the aforementioned challenges, this invention proposes a circulating water cooling device to replace the air cooling device, which can significantly improve the cooling effect, ensure safe production, and enhance product quality. Utility Model Content

[0005] This invention provides a novel partition wall for a pellet ring cooler, which solves the problems of insufficient cooling effect and complex structure of existing ring cooler cooling methods.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A novel partition wall for a pelletizing ring cooler includes a refractory brick partition wall, the exterior of which is provided with refractory castable. The ring cooler partition wall also includes a load-bearing water-cooled partition beam. The load-bearing water-cooled partition beam is a box-shaped wall structure, with one end of the load-bearing water-cooled partition beam connected to an inlet pipe and the other end connected to an outlet pipe.

[0008] Furthermore, the refractory brick partition wall is made of high-alumina monetite brick.

[0009] Furthermore, the load-bearing water-cooled partition beam is located at the lower part of the refractory brick partition wall.

[0010] Furthermore, the box-shaped wall structure is surrounded by welded water-cooled walls, and the refractory brick partition wall is located at the top of the water-cooled walls.

[0011] Furthermore, the load-bearing water-cooled partition beam uses a dual-circuit water-cooled square tube, which is connected to the inlet pipe and the outlet pipe respectively.

[0012] Furthermore, the inlet pipe of the load-bearing water-cooled partition beam is located near the bottom of the load-bearing water-cooled partition beam, and the outlet pipe of the load-bearing water-cooled partition beam is located near the top of the load-bearing water-cooled partition beam.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, all the air-cooled beams in the partition wall of the existing pellet ring cooler are replaced with water-cooled beams. The wall is moved down to replace the partition plate, and the upper part of the bottom load-bearing water-cooled beam is constructed with refractory material. The two ends of the entire water-cooled beam pass through a rotating double-circuit water-cooled square tube for external cooling water circulation, avoiding the water beam's weak points from being burned by high temperature, which could lead to water leakage accidents and affect normal production. This design has a long service life, simple and reliable structure, and can completely solve the risks of partition wall detachment.

[0015] This invention can effectively solve the problem that anchors are easily oxidized and burned in high-temperature environments, leading to the detachment of partitions and the failure of partition walls.

[0016] This invention completely solves the shutdown accident caused by the detachment of the partition wall of the ring-cooled fan, improves the efficiency of the main hot air circulation, and correspondingly improves product output and quality. Attached Figure Description

[0028] This utility model provides a technical solution: a novel partition wall for a pellet ring cooler, such as... Figure 1 As shown, the structure includes a refractory brick partition wall 1, with a height of 1.5 meters, made of high-alumina monetite bricks. The exterior of the wall is constructed of refractory castable 2, with a thickness of 400mm. A load-bearing water-cooled partition beam 5 comprises the entire box-shaped wall. One end of the load-bearing water-cooled partition beam 5 is connected to a water inlet pipe 4, and the other end is connected to a water outlet pipe 3. Water-cooled walls 6 are welded around the entire box-shaped wall. The interior of the load-bearing water-cooled partition beam 5 adopts a dual-circuit water-cooled square tube structure 7.

[0029] Two sets of water-cooled square tubes 7 are arranged vertically, with water-cooled walls 6 welded around them. One end of the square tubes is connected, and cooling water circulates from the lower water pipe to the upper water pipe to cool the internal water-cooled walls. Refractory bricks are laid on top of the water-cooled walls to isolate the first and second high-temperature zones. The cooling water is circulated after being cooled by a cooling water tank.

[0030] In this invention, the load-bearing water-cooled partition beam 5 not only supports the refractory brick partition wall 1 but also rapidly and effectively cools the high-alumina brick layer. This extends the service life of the annular cooler partition wall and effectively prevents localized burn-out caused by insufficient cooling of the partition wall.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
