[0002] With the development of industrial technology, especially in high-temperature and high-pressure operating environments such as chemical and metallurgical industries, the thermal management and cooling systems of equipment have become increasingly important. These industries often require the handling of large quantities of high-temperature materials, making efficient and safe cooling crucial.
[0003] Traditional water cooling devices are typically simple in structure and have limited cooling effect, making it difficult to meet the heat dissipation requirements of large material flows under high load conditions. In addition, existing cooling systems suffer from uneven fluid flow and low cooling efficiency during use, resulting in energy waste, high equipment failure rates, and impacting production efficiency and safety.
[0004] To address the aforementioned issues, a large water-cooled jacket structure is proposed that enhances water cooling efficiency and ensures operation in high-temperature, high-pressure working environments. Utility Model Content

[0030] The first sleeve 1 includes a first cylinder 101, a top flange 103 symmetrically provided on one side of the first cylinder 101, a first stiffening plate 102 connected to the bottom of the top flange 103, and a material flow cylinder 5 connected to the bottom of the first cylinder 101.
[0031] The second sleeve 2 includes a second water-cooled cylinder 201. A pair of water outlets 204 are provided on one side of the top of the second water-cooled cylinder 201. The top of the second water-cooled cylinder 201 is sleeved and connected to the bottom of the first cylinder 101. A second spacer water flange 202 is symmetrically provided on the top of the second water-cooled cylinder 201. A second stiffening plate 203 is provided under each pair of second spacer water flanges 202.
[0032] The third sleeve 3 includes a third water-cooled cylinder 301, the top of the third water-cooled cylinder 301 is sleeved and connected to the bottom of the second water-cooled cylinder 201, and a third spacer water flange 302 is provided at the sleeve connection between the top of the third water-cooled cylinder 301 and the bottom of the second water-cooled cylinder 201.
[0033] The fourth sleeve 4 includes a fourth water-cooled cylinder 401, the top of which is sleeved and connected to the bottom of the third water-cooled cylinder 301. A fourth spacer flange 404 is provided at the connection between the top of the fourth water-cooled cylinder 401 and the bottom of the third water-cooled cylinder 301. A pair of water inlets 402 and a pair of drain outlets 403 are sequentially provided on one side of the outer side of the fourth water-cooled cylinder 401.
[0034] The bottom of the fourth water-cooled cylinder 401 is provided with a support column 6, which consists of a column top plate, a column arc plate, a set of column stiffeners and a set of column side plates.
[0035] The outer side of the first cylinder 101 is fitted with reinforcing channel steel.
[0036] The material flow cylinder 5 is sequentially fitted with a first cylinder 101, a second water-cooled cylinder 201, a third water-cooled cylinder 301, and a fourth water-cooled cylinder 401.
[0037] The first cylinder 101, the second water-cooled cylinder 201, the third water-cooled cylinder 301 and the fourth water-cooled cylinder 401 form a through water flow channel interlayer. The water flow channel is provided with a number of vertically and horizontally distributed water-proof strips 7, and a number of water flow holes are evenly distributed on the water-proof strips 7.
[0038] The outlet 204 is connected to a recycling pipe 8, and the other end of the recycling pipe 8 is connected to a recycling system.
[0039] In operation, the heated bulk material enters the material flow cylinder 5 through the first cylinder 101.

A water flow channel interlayer is provided between the second water-cooled cylinder 201, the third water-cooled cylinder 301, and the fourth water-cooled cylinder 401 and the material flow cylinder 5. Water flows into the water flow channel interlayer through the inlet 402. When the water flows through the water flow holes of the supporting column 6, the flow resistance of the water increases, thereby reducing the water flow velocity. This helps to prolong the contact time between the cold water and the material flow cylinder 5, which needs to be cooled, improving the heat exchange effect. The longer the contact time during the cooling process, the higher the heat exchange efficiency is generally. Under the same temperature difference, a longer heat conduction time allows the cold water to more effectively remove heat from the object being cooled, thus cooling the material inside the material flow cylinder 5. The water in the device can be recycled through the recovery pipe 8 after the temperature rises.
