Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone cone with a cylindrical section. Background Art

[0002] Currently, the cyclone cone consists of a cylindrical section and a conical section. Due to the large size of the cyclone cone, the cylindrical and conical sections are primarily secured together by welding. When slurry swirls at high speed within the cyclone cone, the flowing slurry causes erosion and wear on the welds. Long-term erosion and wear on the welds can affect the reliability of the connection between the cylindrical and conical sections, thereby shortening the service life of the cyclone cone. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a cyclone cone with a cylindrical section. The cyclone cone with the cylindrical section is fixed by a wear-resistant bushing through sleeve connection, which can completely cover the weld between the cylindrical section and the conical section. When the slurry swirls at high speed in the cyclone cone, the scouring and wear of the slurry on the joint is avoided, thereby greatly extending the service life of the cyclone cone.

[0004] In order to solve the above technical problems, the technical solution of the utility model is achieved as follows:

[0005] A cyclone cone with a cylindrical section comprises a cyclone cone, wherein the upper portion of the cyclone cone is a cylindrical section, and the lower portion is a conical section, wherein the cylindrical section and the conical section are welded to each other; a top flange and a bottom flange are welded to the outer sides of the top and bottom of the cyclone cone, respectively; the top flange has a plurality of top positioning holes distributed in a circumferential array, and the bottom flange has a plurality of bottom positioning holes distributed in a circumferential array;

[0006] The cyclone cone is internally fixed with a detachable sleeve having multiple wear-resistant bushings distributed in a circumferential array. All the wear-resistant bushings together constitute a complete annular wear-resistant bushing, which is completely in contact with the inner wall of the cyclone cone and can completely cover the weld between the cylindrical section and the conical section. A first flange is welded and fixed to the top of the wear-resistant bushing, and the first flange is provided with first positioning holes corresponding to the position and number of the top positioning holes.

[0007] By adopting the above solution, the cyclone cone with a cylindrical section is fixed with a wear-resistant bushing by sleeve connection, which can completely cover the weld between the cylindrical section and the conical section. When the slurry swirls at high speed in the cyclone cone, the scouring and wear of the slurry on the joint is avoided, thereby greatly extending the service life of the cyclone cone.

[0008] As a preferred embodiment of the cyclone cone with a cylindrical section, the wall thickness of the wear-resistant bushing is half the wall thickness of the cyclone cone.

[0009] In order to achieve lightweight wear-resistant bushings, the wall thickness of the wear-resistant bushings is designed to be half the wall thickness of the cyclone cone. While ensuring wear resistance, the weight of the wear-resistant bushings is also controlled at a low level.

[0010] As a preferred embodiment of the cyclone cone with a cylindrical section, the wear-resistant bushing is integrally punched through a mold.

[0011] By adopting the above solution, in order to improve the reliability of the overall structure of the wear-resistant bushing, it is formed by integrated stamping, and the overall structure has higher strength and better wear resistance.

[0012] As a preferred embodiment of a cyclone cone with a cylindrical section, the wear-resistant bushing completely covers only the weld between the cylindrical section and the conical section, and the distance between the bottom edge of the wear-resistant bushing and the weld is 30-50 mm.

[0013] With the above solution, if the wear-resistant bushing is only used to prevent erosion and wear of the joint by slurry, the wear-resistant bushing can be made smaller as a whole to only prevent erosion and wear of the joint by slurry, thereby controlling the initial investment cost.

[0014] As a preferred embodiment of a cyclone cone with a cylindrical section, the wear-resistant bushing completely covers the entire inner wall of the cyclone cone; wherein, a second flange is welded and fixed to the bottom of the wear-resistant bushing, and the second flange is provided with second positioning holes corresponding to the position and number of the bottom positioning holes.

[0015] By adopting the above scheme, if the wear-resistant bushing is used to prevent the slurry from scouring and wearing the entire inner wall of the cyclone cone, the wear-resistant bushing can be enlarged as a whole. When the wear-resistant bushing can no longer be used due to scouring and wear, it is only necessary to replace the wear-resistant bushing, which effectively reduces the subsequent maintenance cost; in order to further improve the stability of the wear-resistant bushing, a second flange is used to reinforce the fixation of the bottom of the wear-resistant bushing.

[0016] As a preferred embodiment of a cyclone cone with a cylindrical section, a vertically downward limit pin is welded and fixed to the bottom of the first flange, and a limit hole corresponding to the position and number of the limit pins is opened on the top flange, and the limit pins can be docked and assembled in the limit holes; when the limit pins are docked and assembled in the limit holes, all the first positioning holes correspond to the top positioning holes one by one.

[0017] In the above solution, in order to facilitate the fixation between the wear-resistant bushing and the cyclone cone, the first flange is first limited by the limit pin during installation, thereby facilitating the subsequent fixation of the first flange.

[0018] After adopting the above technical solution, the beneficial effects of the utility model are:

[0019] 1. The cyclone cone with a cylindrical section is fixed with a wear-resistant bushing by sleeve connection, which can completely cover the weld between the cylindrical section and the conical section. When the slurry swirls at high speed in the cyclone cone, the erosion and wear of the slurry on the joint is avoided, thereby greatly extending the service life of the cyclone cone.

[0020] 2. In order to achieve lightweight wear-resistant bushings, the wall thickness of the wear-resistant bushings is designed to be half the wall thickness of the cyclone cone. While ensuring wear resistance, the weight of the wear-resistant bushings is also controlled at a low level.

[0021] 3. In order to improve the reliability of the overall structure of the wear-resistant bushing, it is stamped into an integrated form, which has higher overall structure strength and better wear resistance;

[0022] 4. If the wear-resistant bushing is only used to prevent erosion and wear of the joint by slurry, the wear-resistant bushing can be made smaller as a whole to only prevent erosion and wear of the joint by slurry, thereby controlling the initial investment cost;

[0023] 5. If the wear-resistant bushing is used to prevent slurry from eroding and wearing the entire inner wall of the cyclone cone, the wear-resistant bushing can be made larger. When the wear-resistant bushing cannot be used anymore due to erosion and wear, only the wear-resistant bushing needs to be replaced, which effectively reduces the subsequent maintenance cost. In order to further improve the stability of the wear-resistant bushing, a second flange is used to reinforce the fixation of the bottom of the wear-resistant bushing.

[0024] 6. In order to facilitate the fixation between the wear-resistant bushing and the cyclone cone, the first flange is first limited by a limit pin during installation, thereby facilitating the subsequent fixation of the first flange. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1, as Figures 1 to 7A cyclone cone with a cylindrical section, used in a cyclone, comprises a cyclone cone 1, with a cylindrical section above and a conical section below, the cylindrical section and the conical section being welded to each other. A top flange 2 and a bottom flange 3 are welded to the outer sides of the top and bottom of the cyclone cone 1, respectively. The top flange 2 has a plurality of top locating holes 4 distributed in a circumferential array, and the bottom flange 3 has a plurality of bottom locating holes 5 distributed in a circumferential array. Four wear-resistant bushings 6 are detachably fastened to the interior of the cyclone cone 1 in a circumferential array. Together, these wear-resistant bushings 6 form a complete annular wear-resistant bushing 6, which is fully in contact with the inner wall of the cyclone cone 1 and completely conceals the weld between the cylindrical section and the conical section. A first flange 7 is welded to the top of the wear-resistant bushing 6, which has first locating holes 8 corresponding in position and number to the top locating holes 4. The cyclone cone with a cylindrical section is fixed with a wear-resistant bushing 6 by sleeve connection, which can completely cover the weld between the cylindrical section and the conical section. When the slurry swirls at high speed in the cyclone cone 1, the scouring and wear of the slurry on the joint is avoided, thereby greatly extending the service life of the cyclone cone 1.

[0041] like Figure 6 As shown, the wall thickness of the wear-resistant bushing 6 is half the wall thickness of the cyclone cone 1. In order to achieve lightweight wear-resistant bushing 6, the wall thickness of the wear-resistant bushing 6 is designed to be half the wall thickness of the cyclone cone 1. While ensuring wear resistance, the weight of the wear-resistant bushing 6 is also controlled at a low level.

[0042] like Figures 4 and 5 As shown, the wear-resistant bushing 6 is formed by integral stamping of a mold. In order to improve the reliability of the overall structure of the wear-resistant bushing 6, it is formed by integral stamping, and the overall structure has higher strength and better wear resistance.

[0043] like Figure 6 As shown, the wear-resistant bushing 6 completely blocks only the weld between the cylindrical and conical sections, with the bottom edge of the bushing 6 30-50 mm away from the weld. If the bushing 6 is only used to prevent erosion and wear of the joint by slurry, the bushing 6 can be made smaller to only prevent erosion and wear of the joint by slurry, thereby reducing initial investment costs.

[0044] like Figure 5 、 Figure 7As shown, a vertically downward-pointing stop pin 9 is welded to the bottom of the first flange 7. Stop holes 10 corresponding in position and number to the stop pins 9 are formed on the top flange 2. The stop pins 9 can be butted into the stop holes 10. When the stop pins 9 are butt-fitted into the stop holes 10, all first locating holes 8 correspond vertically with the top locating holes 4. To facilitate the fixation between the wear-resistant bushing 6 and the cyclone cone 1, the first flange 7 is first fixed in position by the stop pins 9 during installation, thereby facilitating subsequent fixation of the first flange 7.

[0045] The working principle of this embodiment is as follows:

[0046] The wear-resistant bushing 6 is only used to prevent erosion and wear at the joints caused by slurry. During use, the wear-resistant bushing 6 is first inserted from the top of the cyclone cone 1 into the interior of the cyclone cone 1. When the stop pin 9 is docked and assembled in the stop hole 10, all the first positioning holes 8 correspond to the top positioning holes 4 one by one. The first flange 7 and the top flange 2 are then fixed together using bolts and nuts, completing the fixed installation of the wear-resistant bushing 6.

[0047] Embodiment 2: The difference between this embodiment and embodiment 1 is that the wear-resistant bushing 6 is used to prevent the slurry from eroding and wearing the entire inner wall of the cyclone cone 1. Figures 8 to 12 As shown, the wear-resistant bushing 6 completely covers the entire inner wall of the cyclone cone 1. A second flange 11 is welded to the bottom of the wear-resistant bushing 6. This second flange 11 is provided with second locating holes 12 corresponding in position and number to the bottom locating holes 5. When the wear-resistant bushing 6 becomes unusable due to erosion and wear, only the wear-resistant bushing 6 needs to be replaced, effectively reducing subsequent maintenance costs. To further enhance the stability of the wear-resistant bushing 6, the second flange 11 is used to reinforce the bottom of the wear-resistant bushing 6.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
