Description

Technical Field

[0001] This utility model belongs to the technical field of cyclone separator center cylinder, specifically relating to a cyclone separator center cylinder with air cooling heat exchange. Background Technology

[0002] The cyclone separator's central cylinder is the core internal component of the cyclone separator. It is typically a coaxially mounted cylindrical or conical hollow cylinder, connected to the exhaust port at the top and suspended inside the separator cavity at the bottom. Its core function is to guide the purified gas out and prevent airflow short-circuiting. As a key channel for gas-solid separation, it forms an annular flow channel with the separator cylinder, causing the dust-laden airflow to throw dust against the cylinder wall under the action of centrifugal force. This prevents the separated dust from being re-entrained by the rising airflow. Furthermore, by precisely controlling the insertion depth and inner diameter to optimize the airflow field and reduce eddy current losses, it directly affects the separator's separation efficiency and pressure drop. Widely used in gas-solid separation systems in industries such as chemical, power, metallurgy, and environmental protection, it is a core component ensuring dust separation accuracy and stable equipment operation. The cyclone separator's central cylinder is also used in air cooling heat exchange processes.

[0003] Chinese patent publication number CN106733244A discloses a central cylinder of a cyclone separator with air cooling and heat exchange, comprising a cyclone separator shell and a central cylinder. The central cylinder is placed inside the cyclone separator shell and consists of upper and lower gas collecting chambers and several cooling heat exchange tubes in the middle. The upper and lower gas collecting chambers are closed cavities with annular shapes. The upper gas collecting chamber is fixedly connected to the top of the cylindrical shell of the cyclone separator. The two ends of the several cooling heat exchange tubes are respectively sealed and inserted into the closed cavities of the upper and lower gas collecting chambers to form the cylinder wall of the central cylinder. The closed cavity of the upper gas collecting chamber is divided into an air inlet chamber and an air outlet chamber, which are connected to the lower gas collecting chamber through the cooling heat exchange tubes. This invention introduces air into the air inlet chamber of the upper gas collecting chamber, so that several cooling heat exchange tubes can cool the central cylinder to prevent thermal deformation; at the same time, high-temperature air is obtained from the air outlet chamber of the upper gas collecting chamber and mixed with high-temperature steam and sent into the gasifier to form a gasifying agent, thereby realizing waste heat recovery.

[0004] However, the following problems exist: Most air-cooled heat exchange cyclone separator center cylinders on the market are not very convenient to use, do not provide easy replacement of the internal power supply fan, increase the probability of structural damage due to long-term operation, increase the difficulty of subsequent maintenance and repair, and reduce the overall service life of the structure. Therefore, we propose an air-cooled heat exchange cyclone separator center cylinder. Utility Model Content

A filter screen frame 20 is fixedly connected to one end of the locking spring 19.

[0022] Based on the structure described above.

[0023] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: an inner support frame 7 is fixedly connected inside the top frame 6, an inner bolt 8 is movably connected to the bottom of the inner support frame 7, an inner connecting plate 9 is movably connected to the outer wall of the inner bolt 8, and an inner motor 10 is fixedly connected to the bottom of the inner connecting plate 9.

[0024] In this embodiment, a leak-proof adhesive strip 21 is fixedly connected to the top of the filter frame 20, and the length and width of the leak-proof adhesive strip 21 are equal to the length and width of the filter frame 20. A mounting bolt 22 is movably connected to one side of the filter frame 20, and a pull handle 23 is movably connected to the outer wall of the mounting bolt 22.

[0025] Based on the structure described above.

[0026] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: the output shaft of the internal motor 10 is fixedly connected to the air supply fan blade 11 via a coupling; the top of the top frame 6 is fixedly connected to the air outlet threaded pipe 12; the outer wall of the air outlet threaded pipe 12 is movably connected to the upper threaded lock buckle 13; the outer wall of the upper frame 1 of the central cylinder is fixedly connected to the outer support frame 14; the bottom of the outer support frame 14 is fixedly connected to the bottom plate 15; and the top of the bottom plate 15 is movably connected to the positioning bolt 16. This makes the central cylinder of the cyclone separator for air cooling and heat exchange more convenient to use, provides easy replacement and maintenance for the internal power supply fan, reduces the probability of structural damage due to long-term operation, lowers the difficulty of maintenance and repair during subsequent use, and improves the overall service life of the structure.

[0027] In this embodiment, a lower bearing 24 is fixedly connected to the bottom of the lower frame 17 of the central cylinder, and the bottom of the lower frame 17 of the central cylinder is only fixedly connected to the top of the outer wall of the lower bearing 24. A guide tube 25 is fixedly connected to the inner wall of the lower bearing 24. The top of the inner plate 9 is movably connected to the bottom of the inner support frame 7 through an inner bolt 8.

Finally, the outlet threaded pipe 12 is locked to the external air inlet pipe by rotating the upper threaded latch 13. When gaseous impurities containing particles enter the upper frame 1 of the central cylinder through the inlet threaded pipe 2, the internal motor 10 also operates. The output shaft of the internal motor 10 rotates, causing the supply fan blades 11 to rotate. The rotation of the supply fan blades 11 causes the airflow inside the upper frame 1 of the central cylinder to rise in a spiral pattern. The particulate matter comes into contact with the interior of the upper frame 1 of the central cylinder along with the airflow, and falls downwards due to gravity. The airflow that removes the particles is discharged through the outlet threaded pipe 12. When the particles reach the filter screen 20, they are... Particle impurities are intercepted by the filter frame 20. Small particles of impurities will enter the guide tube 25 through the filter frame 20. By rotating the guide tube 25, large particles of impurities will fall in the appropriate direction. If it is necessary to clean out large particles of impurities inside the filter frame 20, press the locking arc block 18 to compress the locking spring 19, thereby causing the locking arc block 18 to retract into the filter frame 20. At this time, the filter frame 20 can be pulled out and cleaned by pulling the handle 23. If it is necessary to replace or repair the flow fan blade 11, rotate the top frame 6 to unlock the external threaded connecting pipe wall 4 and the internal threaded connecting pipe wall 5, thereby allowing the inner support frame 7 and the flow fan blade 11 to be pulled out upwards together. Then, rotate the inner bolt 8 to unlock the inner connecting plate 9 and the inner support frame 7. Now the flow fan blade 11 can be repaired or replaced.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
