Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, specifically to a boiler material transport device. Background Technology

[0002] In the operation of thermal power plants, the boiler, as the core equipment for energy conversion, directly affects the economic efficiency and stability of the entire power plant. The boiler's combustion efficiency is inextricably linked to the uniform distribution of fuel. Uniform fuel distribution ensures complete combustion of fuel within the boiler, improving thermal efficiency, reducing unburned losses, and lowering pollutant emissions. Therefore, optimizing the boiler material transport system to achieve precise, efficient, and uniform fuel distribution is of great significance for improving boiler performance and ensuring the safe and economical operation of the power plant.

[0024] The technical solution of this utility model will be further explained and described below with reference to the accompanying drawings and embodiments, but this utility model is not limited to the embodiments described below.

[0025] Reference Figure 1 In existing technology, boiler material conveying devices include a first conveying mechanism 4, a second conveying mechanism 5, an inlet feed pipe 1, an outlet feed pipe 2, and a crusher 3. After being transported from the first conveying mechanism 4 to the inlet feed pipe 1, the material passes sequentially through the crusher 3 and the outlet feed pipe 2, finally reaching the second conveying mechanism 5. However, in order to ensure the normal feeding of the boiler material conveying device, all materials, regardless of whether they require crushing, must pass through the crusher 3. For materials that are dry coal slime or have a suitable particle size, passing the material through the crusher 3 again results in high power consumption for the crusher 3.

[0026] In order to solve the technical problem in the prior art that the material is dry coal slime or the material particle size is qualified, and the material will consume a lot of electricity when it passes through the crusher 3 again, the present invention provides a boiler material transportation device.

[0027] This utility model relates to a boiler material transport device. When the material particle size is unqualified, the material enters the crusher 3 through the inlet pipe 1. The crusher 3 crushes the material and outputs it to the outlet pipe 2. When the material is dry coal slime or has a qualified particle size, the adjusting component 7 is adjusted to connect the inlet pipe 1 to the auxiliary discharge pipe 6, but disconnect the inlet pipe 1 from the crusher 3. The material in the inlet pipe 1 then directly reaches the outlet pipe 2 through the auxiliary discharge pipe 6. The auxiliary discharge pipe 6 and adjusting component 7 allow operators to select the required material transport path based on actual conditions. When the material is dry coal slime or has a qualified particle size, the material does not need to pass through the crusher 3, saving the crusher 3's power consumption.

[0028] Reference Figure 2A boiler material conveying device includes a first conveying mechanism 4, a second conveying mechanism 5, an inlet material pipe 1, an outlet material pipe 2, a crusher 3, a secondary discharge pipe 6, and an adjusting component 7. The first conveying mechanism 4 is connected to the inlet end of the crusher 3 through the inlet material pipe 1; the second conveying mechanism 5 is connected to the output end of the crusher 3 through the outlet material pipe 2; the input end of the secondary discharge pipe 6 is connected to the inlet material pipe 1, and the output end of the secondary discharge pipe 6 is connected to the outlet material pipe 2; the adjusting component 7 is installed at the connection between the secondary discharge pipe 6 and the inlet material pipe 1, and is used to adjust the connection state between the inlet material pipe 1 and the secondary discharge pipe 6.

[0029] Specifically, the material of the outlet pipe 2 is NM500, and the wall thickness of the outlet pipe 2 is 14mm.

[0030] Reference Figure 2 The auxiliary feed pipe 6 includes a first branch pipe 61 and a second branch pipe 62. The input end of the first branch pipe 61 is connected to the inlet feed pipe 1; the input end of the second branch pipe 62 is connected to the output end of the first branch pipe 61, and the output end of the second branch pipe 62 is connected to the outlet feed pipe 2.

[0031] Specifically, an opening with dimensions of 800mm × 700mm is made 60mm from the input end of the inlet pipe 1, and the first branch pipe 61 is connected to the inlet pipe 1. By adjusting the position of the baffle plate 71, the material can enter the crusher 3 directly from the inlet pipe 1 or enter the first branch pipe 61 from the opening of the inlet pipe 1, which makes it convenient for operators to change the material transportation path according to the actual situation.

[0032] More specifically, the first branch pipe 61 is inclined at an angle of 85° to ensure that the material can be smoothly transported from the inlet pipe 1 to the first branch pipe 61, while the second branch pipe 62 is vertically arranged.

[0033] In this invention, the ratio between the input port diameter of the crusher 3 and the diameter of the inlet pipe 1 is in the range of 1:(1-3). Specifically, the ratio between the input port diameter of the crusher 3 and the diameter of the inlet pipe 1 can be 1:1, 1:2, or 1:3. Setting a suitable ratio between the input port diameter of the crusher 3 and the diameter of the inlet pipe 1 ensures that the amount of material entering the crusher 3 from the inlet pipe 1 is appropriate, thus preventing blockage of the crusher 3. Any of these settings are acceptable.

[0034] Reference Figure 2 The auxiliary feed pipe 6 also includes a guide pipe 63. The input end of the guide pipe 63 is connected to the second branch pipe 62, and the output end of the guide pipe 63 is connected to the outlet pipe 2. The guide pipe 63 is inclined from high to low from the side away from the crusher 3 to the side closer to the crusher 3.

[0035] Specifically, the dimensions of the feed pipe 63 are 850mm×750mm. The feed pipe 63 is connected to the second branch pipe 62 through a flange, and the feed pipe 63 is connected to the outlet pipe 2 through a flange.

[0036] In this invention, the inclination angle of the guide pipe 63 ranges from 30° to 60°. Specifically, the inclination angle of the guide pipe 63 can be 30°, 45°, or 60°. Setting a suitable inclination angle of the guide pipe 63 allows the material to be smoothly transported from the second branch pipe 62 to the outlet pipe 2. Any of these settings are acceptable.

[0037] Reference Figure 2 The outlet material pipe 2 includes a vertical section 21 and an inclined section 22. The input end of the vertical section 21 is connected to the output end of the crusher 3, the output end of the vertical section 21 is connected to the inclined section 22, and the vertical section 21 is connected to the output end of the guide pipe 63; the inclined section 22 is connected to the second conveying mechanism 5, and the inclined section 22 is inclined from high to low from the side closer to the crusher 3 to the side farther away from the crusher 3.

[0038] In this invention, the tilt angle of the inclined part 22 is in the range of 30°-60°. Specifically, the tilt angle of the inclined part 22 can be 30°, 45°, or 60°. Setting a suitable tilt angle of the inclined part 22 allows the material to be smoothly transported from the outlet material pipe 2 to the second conveying mechanism 5. Any of these settings are acceptable.

[0039] Reference Figure 2 The adjusting component 7 includes a baffle plate 71, a fixed shaft 72, and a locking component. The fixed shaft 72 is connected to the side of the inlet pipe 1 near the first branch pipe 61; the baffle plate 71 is movably connected to the fixed shaft 72. When the baffle plate 71 rotates to a position where its plane is parallel to the axial direction of the inlet pipe 1, the inlet pipe 1 and the first branch pipe 61 are not connected. When the baffle plate 71 rotates to a position where its plane is parallel to the axial direction of the first branch pipe 61, the inlet pipe 1 and the first branch pipe 61 are connected; the locking component is connected to the baffle plate 71 and is used to fix the position of the baffle plate 71.

[0040] Specifically, the dimensions of the baffle plate 71 are 850mm × 750mm. When the baffle plate 71 is rotated to the point where its plane is parallel to the axial direction of the inlet pipe 1, the baffle plate 71 is in close contact with the wall of the inlet pipe 1 and completely covers the opening on the inlet pipe 1. At this time, the inlet pipe 1 and the first branch pipe 61 are not connected.

[0041] More specifically, the locking element can be a combination of bolts and nuts, a pin, or a spring pin. The locking element is used to fix the position of the baffle plate 71; any of these configurations are acceptable. In this invention, the locking element is a combination of bolts and nuts; a bolt is installed on the baffle plate 71, passing through the baffle plate 71 and the inlet pipe 1, and extending out of the inlet pipe 1. A nut is connected to one end of the bolt extending out of the inlet pipe 1.

[0042] Example 1:

[0043] Reference Figure 2 In this embodiment of the boiler material transport device, the ratio between the input port diameter of the crusher 3 and the diameter of the second branch pipe 62 is 1:1. Specifically, the input port diameter of the crusher 3 and the diameter of the second branch pipe 62 are both 3 meters.

[0044] In this embodiment, the inlet of the crusher 3 and the diameter of the second branch pipe 62 are exactly the same, so the material can maintain a smooth transition when entering the crusher 3 from the second branch pipe 62, reducing the problem of material blockage or poor flow caused by the difference in diameter, thereby improving the working efficiency of the entire boiler material transportation device.

[0045] Example 2:

[0046] Reference Figure 2 In this embodiment of the boiler material transport device, the adjusting component 7 also includes an operating handle 73. The operating handle 73 is connected to the baffle plate 71.

[0047] In this embodiment, an operating handle 73 is provided on the baffle 71, which allows the operator to directly control the position of the baffle 71 by pushing and pulling the operating handle 73, thereby realizing the rapid adjustment of the material transport path.

[0048] Example 3:

[0049] Reference Figure 2 In this embodiment, the boiler material transport device has a first branch pipe 61 that is inclined from high to low from the side closest to the crusher 3 to the side furthest from the crusher 3.

[0050] In this embodiment, the first branch pipe 61 is inclined, so that the material slides down the first branch pipe 61 more smoothly under the action of gravity, reducing the accumulation of material in the first branch pipe 61, improving the material transportation efficiency, and reducing the risk of equipment failure caused by material blockage.

[0051] Example 4:

[0052] Reference Figure 2 In this embodiment, the tilt angle of the guide pipe 63 in the boiler material transport device is 45°.

[0053] In this embodiment, the tilt angle of the guide tube 63 is set to 45° to ensure that the material slides smoothly under the action of gravity, while reducing the collision and friction of the material in the guide tube 63.

[0054] Example 5:

[0055] Reference Figure 2 In this embodiment of the boiler material transport device, the tilt angle range of the tilting part 22 is 45°.

[0056] In this embodiment, the tilt angle of the inclined part 22 is 45°, which ensures that the material slides smoothly under the action of gravity, while reducing the collision and friction of the material in the inclined part 22.

[0057] The working principle of the boiler material transport device of this utility model is as follows: when the particle size of the material is not qualified, the baffle plate 71 is rotated so that the plane of the baffle plate 71 is parallel to the axial direction of the inlet material pipe 1. At this time, the inlet material pipe 1 is connected to the crusher 3, but not connected to the first branch pipe 61. After the material is transported from the first conveying mechanism 4 to the inlet material pipe 1, it passes through the crusher 3 and the outlet material pipe 2 in sequence, and finally is transported to the second conveying mechanism 5 through the outlet material pipe 2.

[0058] When the material is dry coal slime or the material particle size is qualified, the baffle plate 71 is rotated so that the plane of the baffle plate 71 is parallel to the axis of the first branch pipe 61. At this time, the inlet pipe 1 is not connected to the crusher 3, but is connected to the first branch pipe 61. After the material is transported from the first conveying mechanism 4 to the inlet pipe 1, it passes through the first branch pipe 61, the second branch pipe 62, the guide pipe 63, and the outlet pipe 2 in sequence, and finally is transported to the second conveying mechanism 5 through the outlet pipe 2.

[0059] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
