Description

Technical Field

[0001] This utility model relates to the field of fluidized bed boiler construction technology, and in particular to a support device for fixing the cone of a cyclone separator. Background Technology

[0002] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. The main function of a cyclone separator is to remove as many solid particles and droplets as possible from the conveyed gas, thereby achieving gas-solid-liquid separation and ensuring the normal operation of pipelines and equipment.

[0003] Improper installation of a cyclone separator can lead to wear on the separator's outer shell and sealing parts, causing gas or solid leakage; it can also reduce the separator's separation efficiency, thereby affecting the overall system's operating efficiency; incorrect installation may cause excessive stress concentration in a certain area, which could damage the structural integrity of the equipment over time.

[0004] During on-site assembly of cyclone separators, the upper cylindrical and lower conical cylinders need to be vertically lifted using lifting equipment, and their end faces are then fitted together. After fitting, circumferential welding is performed along the outer edge of the mating surfaces to secure the connection. Existing cyclone separators cannot precisely control the position and verticality of the upper cylindrical and lower conical cylinders during assembly, which hinders accurate docking and affects the assembly precision and efficiency of the cyclone separator.

[0041] Example: Figures 1-15 As shown, a support device for fixing the conical cylinder of a cyclone separator includes a bracket 1, a horizontal arc-shaped plate 2, a trapezoidal reinforcing plate 3, an arc-shaped support plate 4, an arc-shaped inclined plate 5, a vertical support plate 6, a stop block 7, a pad plate 8, a sliding support 9, and a bottom fixing steel plate 10. The bracket 1 is a trapezoidal bracket composed of multiple steel plates, including a top plate 11, a bottom plate 12, and two side plates 13. The top plate and bottom plate are fixed to the upper and lower ends of the side plates, and a middle reinforcing plate 14 is provided between the top plate and the bottom plate of the side plates. Eight brackets are evenly distributed along the circumference at a 45° angle. The stop block 7 is divided into eight groups of two blocks each, which are placed on the support. The support structure is designed to limit displacement on both sides. The pad 8, made of flat steel, is used to adjust the levelness of the support and is placed underneath it. Multiple horizontal arc-shaped plates 2, trapezoidal reinforcing plates 3, arc-shaped support plates 4, arc-shaped inclined plates 5, and vertical support plates 6 are interconnected with the support to form a circular support structure. The sliding support 9 ensures the expansion position of the cyclone separator during operation, allowing for smooth sliding with a displacement greater than 15mm, and is located below the support. The bottom fixing steel plate, 30mm thick, is fixed to the beam, and the assembled circular support structure is fixed to the bottom fixing steel plate. An arc-shaped groove 21 is provided on one side of the horizontal arc-shaped plate to accommodate the installation of the arc-shaped inclined plate.

[0042] The on-site construction process for the support device of the fixed cyclone separator cone includes the following installation steps:

[0043] S1. Distribute 8 bottom-fixed steel plates evenly at a 45° angle along the circumference and weld them onto the beam.

[0044] S2. Install the pad and sliding support at the bottom fixed steel plate that has been welded to the beam, located below the bracket;

[0045] S3. On the ground, weld the bracket to multiple horizontal arc-shaped plates, multiple arc-shaped support plates, multiple arc-shaped inclined plates, and multiple trapezoidal reinforcing plates to form a circular ring support structure.

[0046] S4. Before hoisting, the level of the circular support structure should be pre-corrected to ensure that it is at the same height as the support frame;

[0047] S5. The corrected circular support structure is hoisted onto the steel plate using a crane for rough positioning;

[0048] S6. After hoisting, check and adjust the support frame;

[0049] S7. After adjustment, hoist the conical cylinder. Before installing the wear-resistant material, install stops on both sides of the support to limit the displacement of the support.

[0050] This invention solves four key problems in the construction of cyclone separator cones:

[0051] 1) Ensure that the cone of the cyclone separator has reliable support at the same height;

[0052] 2) The sliding support under the bracket ensures that the cyclone separator can move freely during thermal expansion;

[0053] 3) Ensure the verticality of the cyclone separator;

[0054] 4) Reduce the installation workload for construction units.
