[0036] See also Figures 1 to 4 The present invention provides a circulating fluidized bed cyclone separator, and the technical solution is as follows:

[0037] A circulating fluidized bed cyclone separator, comprising:

[0038] A separator body 1, on the wall of which a first annular screen 2 and a second annular screen 3 are respectively provided;

[0039] A first annular box 4, the first annular box 4 is connected to the first annular screen 2, and the first annular box 4 is fixedly installed outside the separator body 1;

[0040] A second annular box 5, the second annular box 5 is connected to the second annular screen 3, and the second annular box 5 is fixedly installed outside the separator body 1;

[0041] The collecting box 6 is fixedly installed at the bottom of the separator body 1. The top wall of the collecting box 6 is fixedly connected with two first vertical pipes 7 and two second vertical pipes 8. The two first vertical pipes 7 are connected to the bottom wall of the first annular box 4, and the two second vertical pipes 8 are connected to the bottom wall of the second annular box 5.

[0042] An atomizer body 31, the atomizer body 31 is fixedly mounted on the top of the separator body 1, and the atomizer body 31 acts on the inside of the air inlet of the separator body 1;

[0043] A heating mechanism 9 for heating the inner wall of the separator body 1 is provided inside the separator body 1 .

[0044] When the airflow enters the separator body 1 tangentially, the airflow rotates in the separator body 1, and the particles in the airflow are thrown out due to the influence of centrifugal force. Particles of different sizes slide along the inner wall of the separator body 1, and the particles of different sizes are collected into the first annular box 4 and the second annular box 5 respectively through the first annular screen 2 and the second annular screen 3. The particles in the first annular box 4 and the second annular box 5 are then collected into the collection box 6 through the first vertical pipe 7 and the second vertical pipe 8. The atomizer body 31 can spray water on the passing airflow to increase the weight of the particles themselves, increase the effect of centrifugal force, and prevent smaller particles from being separated.

[0045] As an embodiment of the present invention, refer to Figure 2 The inner walls of both sides of the air outlet pipe of the separator body 1 are fixedly connected with the same rectangular plate 10, the top center of the rectangular plate 10 is rotatably connected with a transmission rod 11, and the outer side of the transmission rod 11 is fixedly connected with two fan blades 12.

[0046] When the airflow enters the separator body 1, the airflow drives the fan blades 12 to rotate, and the fan blades 12 can further drive the transmission rod 11 to rotate, thereby realizing the utilization of wind energy.

[0047] As an embodiment of the present invention, refer to Figure 2 , the width of the rectangular plate 10 is smaller than the width of the air outlet pipe of the separator body 1.

[0048] The width of the rectangular plate 10 is smaller than the width of the air outlet pipe, thereby preventing the air outlet pipe from being affected in gas discharge due to the excessive width of the rectangular plate 10 .

[0049] As an embodiment of the present invention, refer to Figure 2 The heating mechanism 9 includes a long tube 13, the top end of the long tube 13 is fixedly connected to the bottom end of the transmission rod 11, and a plurality of heating heads 14 are symmetrically rotatably mounted on both sides of the long tube 13.

[0050] The transmission rod 11 drives the long tube 13 to rotate, and the long tube 13 drives the heating head 14 to rotate. The rotation of the heating head 14 can effectively heat the inner wall of the separator body 1, so that the moisture on the surface of the particles attached to the inner wall of the separator body 1 can be evaporated to reduce the adhesion.

[0051] As an embodiment of the present invention, refer to Figure 2A power-carrying spring 15 is fixedly connected to the inner wall of the top side of the long tube 13, and a long rod 16 is fixedly connected to the bottom end of the power-carrying spring 15. Multiple heating heads 14 are rotatably connected to the long rod 16. An induction coil is fixedly installed inside one of the two fan blades 12. A strong magnet 17 is fixedly installed on the inner wall of the top right side of the separator body 1, and the induction coil is electrically connected to the power-carrying spring 15.

[0052] When the fan blade 12 rotates, the induction coil on the fan blade 12 intermittently cuts the magnetic flux lines generated by the strong magnet 17, thereby intermittently generating current. The intermittent current is transmitted to the energized spring 15, thereby causing the energized spring 15 to contract. The contraction of the energized spring 15 drives the long rod 16 to move up and down (in order to ensure that the long rod 16 does not get stuck when driving the heating head 14 to move, the long rod 16 and the heating head 14 can also be connected by a wire rope. The wire rope is made of high temperature resistant material, such as tungsten wire, so as to ensure that the long rod 16 can drive the heating head 14 to move). The long rod 16 drives multiple heating heads 14 to swing. The heating heads 14 swing while rotating, thereby effectively improving the heating efficiency.

[0053] As an embodiment of the present invention, refer to Figure 2 The bottom end of the long tube 13 is fixedly connected with a push rod 18, and the push rod 18 is located at the center of the lower part of the separator body 1.

[0054] The long tube 13 drives the push rod 18 to rotate, and the rotation of the push rod 18 can prevent a large amount of particles from being accumulated and unable to be discharged in time.

[0055] As an embodiment of the present invention, refer to Figure 2 A square plate 19 is fixedly sleeved on the outside of the push rod 18, and scraper rods 20 are fixedly connected on both sides of the left and right sides of the square plate 19 (in order to ensure that the rectangular plate 10 is better stressed, the staff can also rotate the sleeve to connect the support part on the smooth part of the push rod 18, and the support part is connected to the inner wall of 1;).

[0056] The push rod 18 rotates to drive the square plate 19 to rotate, and the square plate 19 rotates to drive the scraper rod 20 to rotate. The rotation of the scraper rod 20 can effectively scrape off the particles on the inner wall of the separator body 1, and can also clear the surface of the first annular screen 2 and the second annular screen 3 to prevent blockage. There are dense scraping hairs on one side of the scraper rod 20.

[0057] As an embodiment of the present invention, refer to Figure 1 and Figure 4 A first collecting box 21 is slidably installed on the inner wall of the collecting box 6, a second collecting box 22 is fixedly connected to one side of the first collecting box 21, a fixing plate 23 is fixedly connected to one side of the collecting box 6, an electric telescopic rod 24 is fixedly installed on the top side of the fixing plate 23, and the output shaft of the electric telescopic rod 24 is fixedly connected to one side of the second collecting box 22.

[0058] The first collecting box 21 and the second collecting box 22 cooperate with each other and are driven by the electric telescopic rod 24, so that the automatic replacement and collection of the particulate matter can be effectively realized.

[0059] As an embodiment of the present invention, refer to Figure 4 A first support plate 25 is slidably connected to the inner wall of the first collection box 21, and four first springs 26 are fixedly connected to the bottom of the first support plate 25. The four first springs 26 are all fixedly connected to the bottom inner wall of the first collection box 21, and a first switch 27 is installed on the bottom inner wall of the first collection box 21.

[0060] The particles in the first collecting box 21 are continuously accumulated and the weight is continuously increased, so that the first supporting plate 25 moves downward. When the first supporting plate 25 moves downward, it squeezes the first switch 27, so that the first switch 27 is turned on. The first switch 27 controls the output shaft of the electric telescopic rod 24 to extend, so that the first collecting box 21 full of particles is pushed out, and the second collecting box 22 takes over the first collecting box 21 to continue collecting the particles.

[0061] As an embodiment of the present invention, refer to Figure 4 A second support plate 28 is slidably connected to the inner wall of the second collection box 22, and four second springs 29 are fixedly connected to the bottom of the second support plate 28. The four second springs 29 are all fixedly connected to the bottom inner wall of the second collection box 22, and a second switch 30 is installed on the bottom inner wall of the second collection box 22.

[0062] The particles in the second collecting box 22 are continuously accumulated and the weight is continuously increased, so that the second support plate 28 moves downward. When the second support plate 28 moves downward, it squeezes the second switch 30, so that the second switch 30 is opened, and the second switch 30 controls the output shaft of the electric telescopic rod 24 to retract, so that the second collecting box 22 full of particles is pulled out, and the first collecting box 21 takes over from the second collecting box 22 to continue collecting the particles, thereby realizing automation. At the same time, partition plates are installed on the inner walls of the first collecting box 21 and the second collecting box 22, and the partition plates can be used to distinguish and collect particles of different sizes.

[0063] Working principle: When the airflow enters the separator body 1 tangentially, the airflow will rotate in the separator body 1, and the particles in the airflow will be thrown out due to the influence of centrifugal force, and particles of different sizes will slide along the inner wall of the separator body 1, and the particles of different sizes will be collected into the first annular box 4 and the second annular box 5 respectively through the first annular screen 2 and the second annular screen 3. The particles in the first annular box 4 and the second annular box 5 are then collected into the collection box 6 through the first vertical pipe 7 and the second vertical pipe 8. The atomizer body 31 can spray water on the passing airflow to increase the weight of the particles themselves, increase the effect of centrifugal force, and avoid that smaller particles cannot be separated. When the airflow enters the separator body 1, the airflow drives the fan blade 12 to rotate, and the fan blade 1 2 can then drive the transmission rod 11 to rotate, realizing the utilization of wind energy. The width of the rectangular plate 10 is smaller than the width of the air outlet pipe, thereby preventing the air outlet pipe from being affected by the excessive width of the rectangular plate 10 and affecting the gas discharge. The transmission rod 11 drives the long tube 13 to rotate, and the long tube 13 drives the heating head 14 to rotate. The rotation of the heating head 14 can effectively heat the inner wall of the separator body 1, thereby evaporating the moisture on the surface of the particles attached to the inner wall of the separator body 1, reducing the adhesion. When the fan blade 12 rotates, the induction coil on the fan blade 12 intermittently cuts the magnetic flux generated by the strong magnet 17, thereby intermittently generating current, and the intermittent current is transmitted to the energized spring 15, thereby causing the energized spring 15 to contract, and the energized spring 15 contracts and drives the long rod 1 6 moves up and down, the long rod 16 drives the multiple heating heads 14 to swing, and the heating heads 14 swing while rotating, so as to effectively improve the heating efficiency, the long tube 13 drives the push rod 18 to rotate, and the rotation of the push rod 18 can prevent a large amount of particles from accumulating and being unable to be discharged in time, the rotation of the push rod 18 drives the square plate 19 to rotate, and the rotation of the square plate 19 drives the scraper rod 20 to rotate, and the rotation of the scraper rod 20 can effectively scrape off the particles on the inner wall of the separator body 1, and at the same time, the surface of the first annular screen 2 and the second annular screen 3 can be dredged to prevent blockage, one side of the scraper rod 20 has dense scraping hairs, the first collection box 21 and the second collection box 22 cooperate with each other, and then cooperate with the electric telescopic rod 24 to drive, so as to effectively realize the automatic replacement of particles. The particles in the first collecting box 21 are continuously accumulated, and the weight is continuously increased, so that the first support plate 25 moves downward. When the first support plate 25 moves downward, it squeezes the first switch 27 to open the first switch 27. The first switch 27 controls the output shaft of the electric telescopic rod 24 to extend, so that the first collecting box 21 full of particles is pushed out. The second collecting box 22 replaces the first collecting box 21 to continue collecting the particles. The particles in the second collecting box 22 are continuously accumulated, and the weight is continuously increased, so that the second support plate 28 moves downward. When the second support plate 28 moves downward, it squeezes the second switch 30 to open the second switch 30. The second switch 30 controls the output shaft of the electric telescopic rod 24 to retract, so that the second collecting box 22 full of particles is pulled out.The first collection box 21 continues to collect the particles instead of the second collection box 22, so that automation can be achieved. At the same time, a partition plate is installed on the inner wall of the first collection box 21 and the second collection box 22, and the partition plate can be used to distinguish and collect particles of different sizes.
