Description
Technical Field
[0001] This utility model belongs to the technical field of circulating fluidized bed boilers, specifically a heat-conducting grid for circulating fluidized bed boilers that facilitates material flow. Background Technology
[0002] A thermally conductive grid for circulating fluidized bed boilers is a metal structural component installed inside the furnace or in key heat transfer areas. It is typically made of alloy materials with high thermal conductivity, providing excellent thermal conductivity and structural strength. Its main functions are to enhance the heat transfer efficiency between the gas and solid phases, improve fluidization quality, promote uniform distribution of the bed material, increase boiler combustion efficiency and heat exchange capacity, and help prevent localized overheating and coking.
[0003] Currently, existing heat-conducting grilles often require multiple pieces to be spliced together to adapt to different boiler sizes. However, the existing connection methods generally have problems such as complex structure and cumbersome installation. Traditionally, bolts or welding are used for fastening, which not only takes a long time to assemble and is labor-intensive, but also makes on-site adjustment difficult and difficult to adapt to changes in boiler structure. After long-term operation, the grilles are prone to loosening or damage, affecting the overall stability and heat transfer effect of the grilles. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a heat-conducting grid for circulating fluidized bed boilers that facilitates the flow of materials. It solves the problems of complex structure and cumbersome installation in existing connection methods. Traditional methods often use bolt fastening or welding for fixing, which not only takes a long time to assemble and is labor-intensive, but also makes on-site adjustment difficult and difficult to adapt to changes in boiler structure. After long-term operation, the grid is prone to loosening or damage, affecting the overall stability and heat transfer effect of the grid.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-conducting grid for a circulating fluidized bed boiler that facilitates material flow, comprising a heat-conducting grid, a connecting plate and a mounting frame installed on the heat-conducting grid, a positioning groove on the mounting frame, two toothed plates slidably installed in the positioning groove, four moving rods slidably installed through the mounting frame, two moving rods forming a group, a connecting rod installed on the two moving rods, the connecting rods being connected to the toothed plates, two toothed plates being installed on the connecting plate, the toothed plates engaging with the toothed plates, four slots being opened in the mounting frame, two compression springs being installed in the slots, a locking block being connected to the compression spring, and a locking groove being opened on the toothed plates.
[0006] As a further embodiment of this utility model: two telescopic rods are installed inside the mounting frame, the ends of the telescopic rods are connected to the toothed plate, and a connecting spring is sleeved on the telescopic rods.
[0007] As a further embodiment of this utility model: two limiting grooves are provided in the mounting frame, and limiting blocks are slidably installed in the limiting grooves, with the limiting blocks connected to the toothed plate.
[0008] As a further embodiment of this utility model: a plurality of hinges are installed on the heat-conducting grid, two hinges forming a group, and an mounting plate is installed on the hinge.
[0009] As a further embodiment of this utility model: the mounting plate has a plurality of mounting holes, and a pinch plate is connected to the mounting plate.
[0010] As a further embodiment of this utility model: the pinch plate is provided with a number of anti-slip patterns, and a number of guiding plates are fixedly installed on the heat-conducting grid.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This heat-conducting grid for circulating fluidized bed boilers, which facilitates material flow, is equipped with toothed plates one and two, a connecting rod, and a telescopic rod. During operation, when connecting the heat-conducting grids, the operator first aligns the connecting plate with the positioning slot, then pushes the heat-conducting grid. The grid moves the connecting plate and toothed plate one, which in turn presses against toothed plate two, causing it to shift until they engage. During the movement of toothed plate two, it presses against the telescopic rod and the connecting spring. The elastic force generated by the connecting spring ensures that toothed plate two firmly engages with toothed plate one. When disassembling the connected heat-conducting grid, simply pull the connecting rod using the hook. The connecting rod moves the moving rod, which in turn moves toothed plate two, separating it from toothed plate one. The connected heat-conducting grid can then be removed quickly, improving work efficiency. 2. This heat-conducting grid for circulating fluidized bed boilers, which facilitates material flow, is equipped with hinges, mounting plates, pinch plates, and mounting holes. During operation, when the heat-conducting grid needs to be installed inside the boiler, the mounting plate is first rotated around the hinge by pinching the plates until several holes on the mounting plate align with the mounting holes on the inner wall of the boiler. Then, the mounting plate and the heat-conducting grid can be quickly installed inside the boiler using bolts. Disassembly is also possible by simply removing the bolts from the mounting holes, facilitating subsequent work and saving time and effort. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0014] like Figure 1-5 As shown, this utility model provides a technical solution: a heat-conducting grid for a circulating fluidized bed boiler that facilitates material flow, comprising a heat-conducting grid 1, on which several hinges 6 are installed, two hinges 6 forming a group, and an mounting plate 4 is installed on the hinges 6. The mounting plate 4 has several mounting holes 19, and a pinch plate 20 is connected to the mounting plate 4. Because of the mounting holes 19, when the several mounting holes 19 on the mounting plate 4 correspond to the mounting holes 19 on the inner wall of the boiler, the mounting plate 4 together with the heat-conducting grid 1 can be quickly installed in the boiler using bolts. When it needs to be disassembled, only the bolts in the mounting holes 19 need to be removed, which facilitates subsequent work and saves time and effort.
[0015] The pinch plate 20 has several anti-slip patterns 21, and the heat-conducting grid 1 has several guide plates 18 fixedly installed. Because of the installation of several guide plates 18, the guide plates 18 can guide and distribute the falling or flowing solid particles, so that the material can be distributed more evenly and avoid local accumulation or channeling.
[0016] A connecting plate 2 and a mounting bracket 3 are installed on the heat conduction grid 1. Two telescopic rods 16 are installed inside the mounting bracket 3. The ends of the telescopic rods 16 are connected to the toothed plate 7. A connecting spring 17 is sleeved on the telescopic rods 16. Because of the installation of the connecting spring 17, the telescopic rods 16 and the connecting spring 17 will be squeezed during the movement of the toothed plate 13. The elastic force generated by the connecting spring 17 will make the toothed plate 13 firmly mesh with the toothed plate 7, thus improving the stability of the device.
[0017] Two limiting grooves 10 are provided in the mounting bracket 3. Limiting blocks 15 are slidably installed in the limiting grooves 10 and are connected to the toothed plate 7.
[0018] The mounting bracket 3 has a positioning groove 5, in which two toothed plates 13 are slidably installed. Four moving rods 22 are slidably installed through the mounting bracket 3, with two moving rods 22 forming a group. A connecting rod 8 is installed on each of the two moving rods 22, and the connecting rod 8 is connected to the toothed plates 13. Two toothed plates 7 are installed on the connecting plate 2, and the toothed plates 7 mesh with the toothed plates 13. The mounting bracket 3 has four slots 9, in which two compression springs 11 are installed. A locking block 12 is connected to the compression spring 11. A locking groove 14 is provided on the toothed plates 13. Because of the locking block 12, when the moving rod 22 moves the toothed plates 13 to a suitable position, the elastic force generated by the compression spring 11 will cause the locking block 12 to engage in the locking groove 14, thereby preventing the toothed plates 13 from resetting.
[0019] The working principle of this utility model is as follows: When it is necessary to connect the heat conduction grid 1, the worker first aligns the position of the connecting plate 2 with the positioning groove 5, and then pushes the heat conduction grid 1. The heat conduction grid 1 drives the connecting plate 2 and the toothed plate 7 to move. The movement of the toothed plate 7 will squeeze the toothed plate 13 and cause it to shift until the toothed plate 7 and the toothed plate 13 mesh. During the movement of the toothed plate 13, it will squeeze the telescopic rod 16 and the connecting spring 17. The elastic force generated by the connecting spring 17 will make the toothed plate 13 firmly mesh with the toothed plate 7. When it is necessary to disassemble the connected heat conduction grid 1, simply use the hook to pull the connecting rod 8. The connecting rod 8 will drive the moving rod 22 to move. The moving rod 22 will drive the toothed plate 13 to move, thereby separating the toothed plate 13 from the toothed plate 7. Then the connected heat conduction grid 1 can be removed. When the heat conduction grid 1 needs to be installed in the boiler, first use the pinch plate 20 to rotate the mounting plate 4 around the hinge 6 until the several holes on the mounting plate 4 correspond to the mounting holes 19 on the inner wall of the boiler. Then, the mounting plate 4 together with the heat conduction grid 1 can be quickly installed in the boiler using bolts. When it needs to be disassembled, simply remove the bolts in the mounting holes 19.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
