Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone technology, and more specifically, to a gas-solid separator device for the conical part of a cyclone. Background Technology
[0002] In the pre-decomposition system of cement production, the conical section of the cyclone separator is a crucial component. Its main function is to guide the raw material-containing airflow into the cyclone separator, where it moves downwards along the inner wall. Upon reaching the cone, the constricting of the cone causes the airflow to converge towards the center. Under centrifugal force, the raw material particles are thrown against the inner wall and slide down to the bottom of the cone, achieving gas-solid separation. However, existing conical sections are generally designed as 60-degree pointed cones, with a relatively simple structure. When the gas rises, it easily carries away particulate solids. Therefore, we propose a gas-solid separator device for the conical section of a cyclone separator. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a gas-solid separator device for the cone section of a cyclone to solve the current technical problem of poor gas-solid separation effect.
[0004] To solve the above technical problems, this utility model provides the following technical solution: a gas-solid separator device for a cyclone cone section, comprising a cone body, the cone body being a hollow cone tip structure, the cone angle of the cone body being 40°, a plurality of spiral guide vanes uniformly installed along the circumferential direction on the inner wall of the cone body, an extension straight handle extending from the connection end of the cone body to the external cyclone, a plurality of central guide vanes arranged inside the extension straight handle, the plurality of central guide vanes being arc fan-shaped structures, the plurality of central guide vanes closely surrounding each other forming a guide cylinder, and the guide cylinder having a cross section with decreasing diameter in the direction of airflow return, compensation plates being provided between adjacent central guide vanes, an inner diameter adjustment structure being provided on one side of the central guide vane, the inner diameter adjustment structure including a hydraulic rod, the driving end of the hydraulic rod being hinged to the central area of one end of the central guide vane, and a plurality of protruding blocking protrusions being provided on the inner wall of the central guide vane.
[0005] Preferably, the helix angle of the helical guide vane is 15°-30°.
[0006] Preferably, the central guide vane has grooves on both sides, the compensation plate is made of a soft material, and the two sides of the compensation plate are inserted into the inner circumference of two adjacent grooves.
[0007] Preferably, multiple elastic connecting posts are connected between the two sides of the compensation piece that it penetrates and the inner wall of the groove, and the elastic connecting posts have the elastic force to tighten the compensation piece.
[0008] Preferably, the inner diameter adjustment structure includes a rod and a tube, which are mutually restrained by tenon joints. The rod and the tube are respectively hinged to the end of the central guide plate away from the hydraulic rod and to the inner wall of the extended straight handle.
[0009] Preferably, the blocking protrusion includes a hemispherical blocking block, and two symmetrical curved slopes are formed on both sides of the bottom of the blocking block. The two curved slopes are arc surfaces that guide the gas to rise, and the middle area of the two curved slopes forms a pointed cone structure from bottom to top.
[0010] Preferably, the airflow guiding direction of the curved slope is tangent to the center of another curved surface on the upper side of the adjacent side.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model uses a guide cylinder composed of central guide vanes to guide the rising airflow to concentrate and pass through the central area, reducing airflow turbulence, making the airflow distribution uniform, avoiding abnormal local airflow velocity, and improving the stability of gas-solid separation. At the same time, through the inner diameter adjustment structure, the diameter of the central guide vanes can be finely adjusted according to the airflow state, optimizing the airflow distribution in the cyclone, improving rotational stability, reducing flow deviation, further enhancing the separation effect, and solving the problem of poor gas-solid separation effect.
[0013] 2. This utility model also uses a unique design of blocking blocks and curved slopes to make solid particles come into contact with and collide with the blocking blocks multiple times during the upward process until they lose power and slide down the inclined surface of the guide cylinder. This effectively prevents solid particles from rising with the airflow. Moreover, this design has little obstruction to the airflow and does not affect the gas recovery, thus improving the purity of gas-solid separation and further solving the problem of poor gas-solid separation effect.
[0014] 3. This utility model also uses a hydraulic rod to drive the central guide vane to move, thereby achieving inner diameter adjustment. This can cope with different working conditions such as uneven airflow or unstable rotation, improving the equipment's adaptability to complex working environments. In addition, the compensation plates set between multiple adjacent central guide vanes can automatically compensate for gaps when the inner diameter of the central guide vane is adjusted, preventing side leakage and ensuring that the equipment can operate stably under different inner diameter conditions, further solving the problem of poor gas-solid separation effect.
[0015] 4. This utility model also adopts a 40° conical angle for the main body of the cone and installs spiral guide vanes on its inner wall with a spiral angle of 15°-30°. Combined with the design of the central guide vane in the extended straight handle, it conforms to the centrifugal force principle of gas-solid separation, which makes the separated solid particles slide down the cylinder wall more smoothly, reduces the possibility of particles being re-entrained by the airflow, improves the efficiency of gas-solid separation, and further solves the problem of poor gas-solid separation effect.

[0023] like Figures 1 to 4 As shown, the present invention relates to a gas-solid separator device for a cyclone cone section, comprising a cone body 1, which is a hollow cone tip structure with a cone angle of 40°. Multiple spiral guide vanes 2 are evenly installed on the inner wall of the cone body 1 along the circumferential direction, with a spiral angle of 15°-30°. An extension straight handle 3 is provided at the connection end between the cone body 1 and the external cyclone. Multiple central guide vanes 4 are arranged inside the extension straight handle 3. The multiple central guide vanes 4 are arc fan-shaped structures. After the multiple central guide vanes 4 are tightly surrounded, they form a guide cylinder, and the guide cylinder has a cross section with decreasing diameter in the direction of airflow return.
[0024] Working principle: By using the flow guide cylinder, the rising airflow can be guided to pass through the central area more concentratedly, reducing airflow turbulence and making the airflow distribution more uniform. This helps to avoid local airflow velocities that are too high or too low, improving the stability and effect of gas-solid separation. This structure also allows the separated solid particles to slide down the cylinder wall more smoothly, reducing the possibility of particles being re-entrained by the airflow.
[0025] To achieve inner diameter adjustment, an inner diameter adjustment structure 6 is also provided on one side of the central guide vane 4. The inner diameter adjustment structure 6 includes a hydraulic rod 601. The driving end of the hydraulic rod 601 is hinged to the central area of one end of the central guide vane 4. The inner diameter adjustment structure 6 also includes a rod body 602 and a tube body 603. The rod body 602 and the tube body 603 are mutually restrained by tenon joints. The rod body 602 and the tube body 603 are respectively hinged to the end of the central guide vane 4 away from the hydraulic rod 601 and the inner wall of the extended straight handle 3. The operation of the hydraulic rod 601 can drive the central guide vane 4 to move, thereby further realizing the adjustment of the inner diameter.
[0026] It is worth mentioning that by reasonably adjusting the diameter, the flow pattern and distribution of airflow can be changed. When local unevenness or unstable rotation of airflow is found, the diameter can be finely adjusted to guide the airflow to be more evenly distributed in the cyclone, making the rotation of airflow more stable. For example, in some cases, the airflow may deviate on one side of the cyclone, resulting in a decrease in separation effect. At this time, by adjusting the diameter of the central structure, the airflow can be redistributed, reducing the deviation phenomenon and improving the stability of gas-solid separation.
[0027] To accommodate the adjustment of the inner diameter, a compensation plate 5 is provided between each of the multiple central guide vanes 4. The central guide vanes 4 have grooves on both sides. The compensation plate 5 is made of soft material. The two sides of the compensation plate 5 are inserted into the inner circumference of two adjacent grooves. Multiple elastic connecting posts 8 are connected between the two sides of the compensation plate 5 and the inner wall of the groove. The elastic connecting posts 8 have the elastic force to tighten the compensation plate 5.
[0028] Working principle: By using the soft material of the compensation plate 5 and the tension of the elastic connecting column 8, the gap between multiple central guide plates 4 can be compensated when the inner diameter is enlarged, thus avoiding side leakage. When the inner diameter is reduced, the compensation plate 5 can be automatically pulled into the inside of the groove by the tensioning force, thus avoiding excess on the outer periphery.
[0029] To further prevent solid particles from rising back, the inner wall of the central guide vane 4 is also provided with multiple protruding blocking protrusions 7. The blocking protrusions 7 include a hemispherical blocking block 701. Two symmetrical curved slopes 702 are opened on both sides of the bottom of the blocking block 701. The two curved slopes 702 are curved surfaces that guide the gas to rise. The middle area of the two curved slopes 702 forms a pointed cone structure from bottom to top. The airflow guiding direction of the curved slope 702 is tangent to the center of the other curved surface on the upper side of the adjacent side. Through the tangent relationship, the particles can contact and collide with the blocking block 701 in turn during the rising process.
[0030] Working principle: When the airflow rises, solid particles can flow upwards in a meandering manner within the gaps of the guide cylinder. Under the action of centrifugal force and gravity, the solid particles encounter the blocking block 701. Following the airflow guidance design, the solid particles can sequentially contact and collide with the blocking block 701 until they lose power and slide down along the inclined surface of the guide cylinder, effectively preventing the solid particles from rising with the airflow. At the same time, the smooth spherical surface, rising arc surface, and the formed pointed cone structure design of the blocking block 701 minimize the obstruction to the airflow, so as not to affect the gas's return.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
