Description

Technical Field

[0001] This invention relates to the field of cyclone separation technology, and in particular to a cyclone separator for a circulating fluidized bed boiler. Background Technology

[0002] A cyclone separator, also known as a cyclone extruder, is a device used for separating gas-solid or liquid-solid systems. The main working principle of a cyclone separator is based on centrifugal force. When gas containing impurities such as dust and droplets enters the cyclone tangentially, the rotation generates a large inertial centrifugal force, causing solid particles or droplets to be thrown against the outer wall and separated. A cyclone separator mainly consists of an air inlet, a cyclone tube, and cyclone blades. Its internal structure helps accelerate gas rotation, thus more effectively separating solid particles. Cyclone separators are widely used in industries such as chemical, pharmaceutical, building materials, and food, effectively purifying gases and reducing environmental pollution.

[0003] When the cyclone separator is separating particles, the falling particles may cause blockages in the discharge pipes. Furthermore, since the cyclone separator is a single unit, it needs to be disassembled to clear the internal blockages, which will affect work efficiency and increase working time.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1 to 8 This is the first embodiment of the present invention, which provides a circulating fluidized bed boiler cyclone separator capable of separating solid-liquid systems and reducing environmental pollution. It includes a separation assembly 100, comprising an inlet 101, a separation element 102 disposed below the inlet 101, an outlet pipe 103 disposed below the separation element 102, and a sliding cylinder 103a disposed inside the outlet pipe 103; and...

[0033] The filter assembly 200 includes a filter frame 201 disposed inside the sliding cylinder 103a; and,

[0034] The self-locking assembly 300 includes a fixed cylinder 301 disposed inside the sliding cylinder 103a and a sliding cover 302 disposed outside the fixed cylinder 301; and,

[0035] The striking component 600 includes a connecting plate 601 disposed inside the sliding cylinder 103a and a protrusion 602 disposed between the connecting plate 601.

[0036] The separation assembly 100 also includes a first elastic member 103a-1 disposed inside the output tube 103 and a connecting tube 104 disposed below the output tube 103, with a storage compartment 105 provided at one end of the connecting tube 104.

[0037] Specifically, the cyclone separator is first started. Workers place the material to be separated into the separator 102 through the inlet 101. The cyclone separator separates the material into gas and solid. After separation, the solid particles fall along the side of the separator 102. When the material falls frequently, the outlet pipe 103 becomes blocked. Due to the gravity of the material accumulated in the blockage, the filter assembly 200 moves downward. When the filter assembly 200 moves to the boundary of the sliding cylinder 103a, the filter assembly 200 drives the sliding cylinder 103a to descend. The sliding cylinder 103a drives the self-locking component 300 to knock on the filter assembly 200. The vibration generated by knocking on it resolves the blockage in the cyclone separator.

[0038] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. This embodiment provides a circulating fluidized bed boiler cyclone tube, which can achieve the effect of clearing blockages in pipelines. It includes a filter assembly 200 and T-shaped blocks 202 disposed on both sides of the filter frame 201. A second elastic member 203 is provided below the T-shaped blocks 202.

[0039] The striking assembly 600 also includes an arc-shaped gear 603 disposed between the connecting plates 601, a protrusion 602 connected to the arc-shaped gear 603, and a toothed plate 604 disposed inside the output tube 103, with the arc-shaped gear 603 meshing with the toothed plate 604.

[0040] Specifically, when blockage occurs in the output pipe 103, the weight of the material piled on top of the filter frame 201 causes the filter frame 201 to move downwards. When the filter frame 201 moves to the bottom edge of the sliding cylinder 103a, the filter frame 201 drives the sliding cylinder 103a to move downwards. During the downward movement of the sliding cylinder 103a, the arc gear 603 meshes with the toothed plate 604, thereby driving the arc gear 603 to rotate. The arc gear 603 drives the protrusion 602 to rotate. When the protrusion 602 rotates, it knocks on the filter frame 201, causing the filter frame 201 to vibrate. The vibration shakes off the blockage particles, thus solving the problem of cyclone blockage.

[0041] Example 3, referring to Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a cyclone separator for a circulating fluidized bed boiler, which can achieve the effect of dispersing high-temperature sticky particles. It includes a self-locking assembly 300 and a connecting protrusion 301a disposed on the outside of a fixed cylinder 301. A self-locking rod 301b is provided inside the connecting protrusion 301a. A curved block 301c is provided at one end of the self-locking rod 301b. A third elastic element 303 is provided inside the fixed cylinder 301. A telescopic rod 304 is provided inside the third elastic element 303. A first connecting rod 305 is provided at one end of the telescopic rod 304. A √-shaped groove 305a is provided on the outside of the first connecting rod 305. The curved block 301c is connected to the √-shaped groove 305a. A second connecting rod 306 is provided at one end of the first connecting rod 305. A rotating plate 307 is provided at one end of the second connecting rod 306. A limiting rod 308 is provided at one end of the rotating plate 307.

[0042] The sliding cylinder 103a is provided with a dispersing component 400. The dispersing component 400 includes a connecting block 401 located inside the sliding cylinder 103a. The connecting block 401 is provided with an output rod 402 located inside the connecting block 401. A coil spring 402a is provided on the outside of the output rod 402. A dispersing blade 403 is provided on the outside of the connecting block 401.

[0043] The output rod 402 has a limiting groove 308a inside, and the limiting rod 308 is set in the limiting groove 308a.

[0044] The sliding cylinder 103a is equipped with a reset assembly 500. The reset assembly 500 includes an inclined arc block 501 disposed inside the sliding cylinder 103a. The inclined arc block 501 has a first arc plate 501a inside. The sliding cylinder 103a is equipped with a fixed arc block 502. The fixed arc block 502 has a rotating arc plate 502a inside. The fixed arc block 502 has a second arc plate 502a-1 inside. A fourth elastic element 502a-2 is provided between the first arc plate 501a and the second arc plate 502a-1. A reset rod 503 is provided between the rotating arc plate 502a and the output rod 402. The filter frame 201 has inclined blocks 504 on both sides. When the filter frame 201 rises, the inclined blocks 504 on both sides of the filter frame 201 press against the inclined surface of the inclined arc block 501, causing the inclined arc block 501 to move towards the fixed arc block 502 and press against the rotating arc plate 502a inside the fixed arc block 502, causing the rotating arc plate 502a to rotate. During the rotation of the rotating arc plate 502a, the reset rod 503 is driven to rotate. The reset rod 503 drives the output rod 402 to rotate. The output rod 402 drives the connecting block 401 and the disintegrating blade 403 to reset.

[0045] Specifically, when the filter frame 201 moves downward, it presses against the sliding cover 302, causing the sliding cover 302 to move inward. The sliding cover 302 then drives the telescopic rod 304, the first connecting rod 305, the second connecting rod 306, and the limiting rod 308 to move inward. During the movement of the first connecting rod 305, the curved block 301c drives the first connecting rod 305 to rotate one revolution through the √-shaped groove 305a. The √-shaped groove 305a drives the second connecting rod 306, the rotating plate 307, and the limiting rod 308 to rotate one revolution. At this time, the limiting rod 308 is removed from the limiting groove 308a, thereby releasing the limitation on the output rod 402. Then, the coil spring 402a in the output rod 402 drives the dispersing blade 403 to swing. Thus, the multiple dispersing blades 403 in the sliding cylinder 103a swing, thereby dispersing the material that is stuck together due to high temperature and filtering it out.
