Description

Technical Field

[0001] The utility model relates to the technical field of steel structure equipment, in particular to a stable steel structure for a boiler steel frame. Background Art

[0002] Industrial boilers are divided into two categories. The first is steam, used for power generation or gas supply. For example, fertilizer plants use steam to vaporize coal to synthesize fertilizer. This is a typical industrial boiler. Coal-fired boilers still account for the majority of industrial boilers, while gas-fired ones are generally waste heat boilers used to recover waste heat. The most common industrial boiler is a circulating fluidized bed boiler. Industrial boilers are important thermal power equipment.

[0003] The application number is CN201821739288.4, which discloses a stable steel structure for a boiler steel frame, and relates to the technical field of boiler installation equipment. It includes a shock-absorbing mechanism, which includes a lower steel plate, a shock-absorbing pad, an upper steel plate and a locking mechanism. The upper surface of the lower steel plate is fixedly fitted with a shock-absorbing pad, and the upper surface of the shock-absorbing pad is fixedly installed with an upper steel plate. The lower steel plate, the shock-absorbing pad and the upper steel plate are fixedly connected by a locking mechanism. The left and right edges of the upper surface of the upper steel plate are fixedly installed with steel beam seats. The steel beam seats are I-shaped structures, and the upper surfaces of the steel beam seats are fixedly installed with mounting plates, and the upper surfaces of the mounting plates are fixedly installed with support legs. The utility model can effectively reduce the vibration of the support legs through the shock-absorbing mechanism, and at the same time reduce the vibration of the boiler body caused by external forces. Then, the support legs, the reinforcing plates and the steel beam seats are formed into a whole through the stabilizing mechanism, so that the strength is high, the force is more uniform, and the boiler installation is more stable and firm.

[0004] The above document discloses a stable steel structure for a boiler steel frame having the following defects: when the boiler is in use, the boiler needs to be fixed to the ground. The structure is set as an integrated structure and cannot be adapted for use with a variety of boilers, thus lacking practicality.

[0005] It can be seen from this that the existing stable steel structure does not have the function of being easily disassembled and assembled to adapt to the use of multiple boilers. It is necessary to improve the existing deficiencies and provide a function that can adapt to the use of multiple boilers. Utility Model Content

[0006] The purpose of the present utility model is to provide a stable steel structure for a boiler steel frame to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a stable steel structure for a boiler steel frame, comprising a cabinet structure and a cabinet door structure, wherein the cabinet door structure is slidably connected to the inner walls on both sides of the cabinet structure, the cabinet structure comprises a shell, and a limiting plate and a clamping block are respectively welded to the inner walls on both sides of the shell, the clamping block is located below the limiting plate, a placement frame is slidably connected between the limiting plate and the clamping block, air vents are opened on the outer walls around the placement frame, and a cabinet door is welded to the opening of the placement frame near the shell. The purpose of this arrangement is that during use of the steel structure, the boiler is placed in the placement frame and pushed by the handle. The handle drives the cabinet door and the placement frame to slide within the limit plate and the clamping block. The placement frame keeps the boiler in the cabinet structure, and the cabinet structure protects the boiler exterior. This structure facilitates boiler replacement and use. Air enters the cabinet structure through the ventilation pipe, and then enters the placement frame through the air vent to dissipate heat from the boiler exterior. The air is then dissipated outward through the ventilation pipe on the other side. The ventilation pipe opening can be sealed by the sealing cover, and the loose hoop reinforces the connection between the sealing cover and the ventilation pipe. When the boiler is not in operation, the boiler exterior is protected from dust. The operation of the boiler will generate vibration. By rotating the rotating block, the rotating block drives the locking ring to move toward the hook body, and the locking ring is put on the hook body. The cabinet door and the shell seal the boiler exterior, preventing the boiler exterior from being damaged by collision. The placement frame is fixed in the shell, allowing the boiler to operate stably inside. The cabinet structure and boiler are supported on the ground by four support blocks. The support height of the support blocks can be adjusted by using slide grooves. The support blocks are fixed to the shell by bolts, which facilitates adjustment and enhances the flexibility of the device.

[0009] Furthermore, four support blocks are provided on the outer walls of both sides of the bottom of the shell. These four support blocks have sliding grooves on their outer walls, and bolts are slidably connected to the inner walls of these grooves. The bottom ends of these bolts extend to the inner walls of the shell. This arrangement allows the cabinet structure and boiler to be supported on the ground by the four support blocks during use. The support blocks can be adjusted in height using the sliding grooves, and the support blocks are fixed to the shell using bolts, making adjustment easy.

[0010] Furthermore, four ventilation pipes are provided on the outer walls of both sides of the housing. Sealing caps are fitted at the openings of the four ventilation pipes, and a flexible collar is provided on the outer wall of the sealing caps. This arrangement ensures that, during use of the steel structure, air flows through the ventilation pipes into the cabinet structure, then into the placement frame through the air vents to dissipate heat to the exterior of the boiler. Air flows outward through the ventilation pipes on the other side. The sealing caps seal the ventilation pipe openings, and the flexible collars reinforce the connection between the sealing caps and the ventilation pipes.

[0011] Furthermore, two fixed blocks are welded to the outer walls of the housing near the cabinet door, and rotating blocks are rotatably connected to the inner walls of the two fixed blocks. The purpose of this arrangement is that when the steel structure is in use, the rotating blocks can drive the lock ring to move toward the hook body by rotating the rotating blocks.

[0012] Furthermore, a locking ring is rotatably connected to the inner wall of the rotating block. Hooks are provided on the outer walls of both sides of the cabinet door, and the locking rings are sleeved onto the inner walls of the hooks. This arrangement allows the cabinet door and the housing to seal the boiler exterior by fitting the locking rings onto the hooks during use.

[0013] Furthermore, a handle is provided on the outer wall of the cabinet door. The purpose of this arrangement is that when the steel structure is in use, the handle is held and pushed, and the handle drives the cabinet door and the placement frame to slide within the limit plate and the clamping block. The placement frame places the boiler within the cabinet structure, and the cabinet structure protects the exterior of the boiler.

[0014] The utility model has the following beneficial effects:

The purpose of such arrangement is that, during the use of the steel structure, the boiler is placed in the placement frame 201, and the handle 205 is held to push it. The handle 205 drives the cabinet door 203 and the placement frame 201 to slide in the limit plate 109 and the clamping block 110. The placement frame 201 places the boiler in the cabinet structure 1, and the cabinet structure 1 protects the outside of the boiler. This structure is convenient for replacing and using the boiler. The airflow enters the cabinet structure 1 through the ventilation pipe 104, and the airflow enters the placement frame 201 through the air vent 202 to dissipate heat to the outside of the boiler. The airflow is emitted outward through the ventilation pipe 104 on the other side. The opening of the ventilation pipe 104 can be sealed by the sealing cover 105, and the hoop 106 connects the sealing cover 105 with the ventilation pipe 104. The connection is reinforced. When the boiler is not in operation, the outside of the boiler is protected from dust. The operation of the boiler will generate vibration. By rotating the rotating block 108, the rotating block 108 drives the locking ring 111 to move toward the hook body 204, and the locking ring 111 is put on the hook body 204. The cabinet door 203 and the shell 101 seal the outside of the boiler to prevent the outside of the boiler from being damaged by collision.
