Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature material cooling devices, and in particular to a stepped material fluidization cooling device. Background Technology

[0002] Cooling high-temperature materials is a crucial step in industrial production. Traditional cooling devices typically employ a single cooling method, such as natural cooling, air cooling, or water cooling. However, these methods suffer from low cooling efficiency, high energy consumption, and large footprint. Furthermore, when handling high-temperature materials, traditional cooling devices are prone to localized overheating, leading to material performance degradation or equipment damage. Therefore, developing a highly efficient, energy-saving, and reliable cooling device is of great significance. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model designs a stepped material fluidization cooling device, which improves cooling efficiency, reduces energy consumption, and ensures uniform cooling of materials through multi-stage fluidization cooling.

[0004] The present invention adopts the following technical solution:

[0005] A stepped material fluidized bed cooling device includes a main body with a cooling material inlet and a cooling material outlet. The main body contains multiple cavities arranged sequentially, each cavity housing a primary cooling unit. These multiple cooling units are distributed in a stepped manner. Each cooling unit consists of a fluidizing device, a fluidizing air channel, a material conveying system, and a weir wall. The weir walls of several cooling units include fixed and movable weir walls. A sling traction device is correspondingly installed above the movable weir wall on the main body, controlling the raising and lowering of the movable weir wall. Cooling air enters through the bottom of the fluidized bed in the fluidizing device, ensuring full contact with the material and achieving efficient cooling. The material then tumbles over the weir wall to enter the next stage or flows out.

[0006] Preferably, the fluidization device includes a fluidized bed with a porous distribution plate design and a slag discharge port in the middle. This ensures uniform distribution of the cooling medium, avoids localized overcooling or overheating, and simultaneously removes agglomerated particles formed during the cooling process.

[0007] Preferably, an air outlet is provided on the main body above the outlet end of the cooling material.

[0008] Preferably, each cavity is equipped with a temperature gauge and a pressure gauge. The temperature and flow rate of the cooling medium in each cooling unit can be adjusted according to the material temperature to ensure the uniformity and efficiency of the cooling process.

[0009] Preferably, each cavity is provided with an inspection door.

[0010] Preferably, there are four cavities, namely a primary cavity, a secondary cavity, a tertiary cavity, and a quaternary cavity. The fluidizing devices and fluidizing air channels in the cavities are respectively the primary cavity fluidizing device and fluidizing air channel, the secondary cavity fluidizing device and fluidizing air channel, the tertiary cavity fluidizing device and fluidizing air channel, and the quaternary cavity fluidizing device and fluidizing air channel. The fan of each fluidizing device is set separately.

[0011] The beneficial effects of this utility model are: (1) In this utility model, a fluidized bed is used for material fluidization, which has a good cooling effect; the stepped fluidized bed distribution results in a uniform temperature drop, avoiding large temperature differences that could damage the equipment; (2) In this utility model, the secondary and tertiary cavities can participate in fluidization and cooling as needed, providing flexibility for adjustment and enhancing the applicability of materials; (3) In this utility model, the movable weir wall is tractioned by a sling, making it easy to move and sensitive to adjustment.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0018] Example: Figures 1-4As shown, a stepped material fluidization cooling device includes a body 1, which contains four chambers arranged in sequence: a primary chamber 4-1, a secondary chamber 4-2, a tertiary chamber 4-3, and a quaternary chamber 4-4. The body 1 is provided with a material inlet 5, a material outlet 6, and an air outlet 9. Each chamber is provided with a primary cooling unit, an inspection door 10, a thermometer 11, and a pressure gauge 12. Each cooling unit consists of a fluidizing device, a fluidizing air channel, a material conveying system, and a weir. The fluidizing devices and fluidizing air channels in each chamber are respectively: primary chamber fluidizing device and fluidizing air channel 7-1, secondary chamber fluidizing device and fluidizing air channel 7-2, tertiary chamber fluidizing device and fluidizing air channel 7-3, and quaternary chamber fluidizing device and fluidizing air channel 7-4.

[0019] The weirs are classified into four stages: primary cavity weir 2-1, secondary cavity weir 2-2, tertiary cavity weir 2-3, and quaternary cavity weir 2-4. The secondary cavity weir 2-2 includes a fixed secondary cavity weir and a movable secondary cavity weir 3-1, and the tertiary cavity weir 2-3 includes a fixed tertiary cavity weir and a movable tertiary cavity weir 3-2.

[0020] This stepped material fluidization cooling device can be used in the following three ways:

[0021] Method 1: The material enters the primary chamber 4-1 through material inlet 5. The particles are fluidized and cooled by the fluidizing device and fluidizing air channel 7-1 in the primary chamber. After fluidization, the particles overcome the primary chamber weir wall 2-1. The particles enter the secondary chamber 4-2, where they are fluidized and cooled by the fluidizing device and fluidizing air channel 7-2. At this time, the secondary chamber moving weir wall 3-1 is not working. After fluidization, the particles overcome the secondary chamber moving weir wall 3-1. The particles enter the tertiary chamber 4-3, where they are fluidized and cooled by the fluidizing device and fluidizing air channel 7-3. The tertiary chamber moving weir wall 3-2 is not working. After fluidization, the particles overcome the tertiary chamber moving weir wall 3-2. The particles enter the quaternary chamber 4-4, where they are fluidized and cooled by the fluidizing device and fluidizing air channel 7-4. After fluidization, the particles overcome the quaternary chamber weir wall 2-4 and enter the material outlet 6, where the fluidization and cooling process ends.

[0022] In this method, each cavity of the main body 1 is equipped with a temperature gauge 11-1 and a pressure gauge 11-2 to monitor the state of particles in the cooling device and to determine the running status of particles and the cooling effect by pressure and temperature.

[0023] In this method, the secondary cavity fluidization device and fluidizing air channel 7-2 and the tertiary cavity fluidization device and fluidizing air channel 7-3 participate in the particle fluidization cooling work; the secondary cavity moving weir wall 3-1 and the secondary cavity moving weir wall sling traction device 8-1 and the tertiary cavity moving weir wall 3-2 and the tertiary cavity moving weir wall sling traction device 8-2 do not work; the weir wall does not move upward, there is no channel between the secondary cavity moving weir wall 3-1 and the secondary cavity fixed weir wall, and there is no channel between the tertiary cavity moving weir wall 3-2 and the tertiary cavity fixed weir wall;

[0024] Method 2: The material enters the primary chamber 4-1 through material inlet 5. The particles undergo fluidization and cooling via the fluidizing device and fluidizing air channel 7-1. After fluidization, the particles overcome the primary chamber weir wall 2-1. The particles then enter the secondary chamber 4-2. There, the particles do not undergo fluidization and cooling via the secondary chamber fluidizing device and fluidizing air channel 7-2. At this time, the secondary chamber moving weir wall 3-1 operates, and the particles flow through the particle flow channel between the secondary chamber moving weir wall 3-1 and the secondary chamber fixed weir wall. The particles enter the third-stage cavity 4-3, where they undergo fluidization and cooling without fluidization through the fluidization device and fluidizing air channel 7-3. The moving weir wall 3-2 of the third-stage cavity is in operation, and the particles flow through the particle flow channel between the moving weir wall 3-2 and the fixed weir wall of the third-stage cavity. The particles then enter the fourth-stage cavity 4-4, where they undergo fluidization and cooling through the fluidization device and fluidizing air channel 7-4. After fluidization, the particles cross the fourth-stage cavity weir wall 2-4 and enter the material outlet 6, thus ending the fluidization and cooling process.

[0025] In this method, each cavity of the main body 1 is equipped with a temperature gauge 11-1 and a pressure gauge 11-2 to monitor the state of particles in the cooling device and to determine the running status of particles and the cooling effect by pressure and temperature.

[0026] In this method, the secondary cavity fluidization device and fluidizing air channel 7-2 and the tertiary cavity fluidization device and fluidizing air channel 7-3 do not participate in the particle fluidization cooling operation; the secondary cavity moving weir wall 3-1 and the secondary cavity moving weir wall suspension cable traction device 8-1 and the tertiary cavity moving weir wall 3-2 and the tertiary cavity moving weir wall suspension cable traction device 8-2 are in operation; the weir wall moves upward, there is a channel between the secondary cavity moving weir wall 3-1 and the secondary cavity fixed weir wall, and there is a channel between the tertiary cavity moving weir wall 3-2 and the tertiary cavity fixed weir wall;

[0027] Method 3: The material enters the primary chamber 4-1 through material inlet 5. The particles undergo fluidization and cooling via the fluidizing device and fluidizing air channel 7-1. After fluidization, the particles overcome the primary chamber weir wall 2-1. The particles then enter the secondary chamber 4-2, where they undergo fluidization and cooling via the secondary chamber fluidizing device and fluidizing air channel 7-2. At this time, the secondary chamber moving weir wall 3-1 is not in operation. After fluidization, the particles overcome the secondary chamber moving weir wall 3-1. The particles then enter the tertiary chamber 4. -3, the particles do not undergo fluidization and cooling when passing through the three-stage cavity fluidization device and fluidizing air channel 7-3. The three-stage cavity moving weir 3-2 is in operation, and the particles flow through the particle flow channel between the three-stage cavity moving weir 3-2 and the three-stage cavity fixed weir. The particles enter the four-stage cavity 4-4, where they undergo fluidization and cooling through the four-stage cavity fluidization device and fluidizing air channel 7-4. After fluidization, the particles cross the four-stage cavity weir 2-4 and enter the material outlet 6, at which point the fluidization and cooling process ends.

[0028] In this method, each cavity of the main body 1 is equipped with a temperature gauge 11-1 and a pressure gauge 11-2 to monitor the state of particles in the cooling device and to determine the running status of particles and the cooling effect by pressure and temperature.

[0029] In this method, the secondary cavity fluidization device and fluidizing air channel 7-2 participate in the particle fluidization and cooling work, while the tertiary cavity fluidization device and fluidizing air channel 7-3 do not participate in the particle fluidization and cooling work; the secondary cavity moving weir wall 3-1 and the secondary cavity moving weir wall traction device 8-1 are not working, while the tertiary cavity moving weir wall 3-2 and the tertiary cavity moving weir wall traction device 8-2 are working; the tertiary cavity moving weir wall moves upward, there is no channel between the secondary cavity moving weir wall 3-1 and the secondary cavity fixed weir wall, and there is a channel between the tertiary cavity moving weir wall 3-2 and the tertiary cavity fixed weir wall.
