Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a grate for a boiler. Background Art

[0002] A grate is a component in a boiler or industrial furnace that stacks solid fuel and enables its efficient combustion. The entire grate mainly includes a frame and a grate. The grate bars are usually made of cast iron, maintaining necessary ventilation gaps, and often a ventilation chamber is also provided below the grate to allow air to enter the fuel layer through the gaps for combustion.

[0003] In boiler design, as the core component of the combustion chamber, the stable installation of the grate ensures the stability and safety of the combustion process. However, a major challenge in current designs is the lack of an automated and efficient ash removal system. As combustion continues, ash and residues will inevitably accumulate above the grate. Traditional manual cleaning methods are not only time-consuming and laborious but also increase unnecessary labor costs. If these accumulations are not removed in a timely manner, they will gradually block the grate, hinder air circulation, and thus have a serious negative impact on the combustion efficiency of the fuel.

[0004] Therefore, a grate for a boiler is needed to solve the above problems. Summary of the Utility Model

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0029] Referring to Figures 1-5 , for an embodiment of the present utility model, a grate for a boiler is provided, which includes:

[0030] A main body unit 100, the main body unit 100 includes a boiler body 101, a combustion chamber is provided inside the boiler body 101, a mounting frame 104 is fixedly connected to the inner wall of the combustion chamber, a boiler grate 105 is arranged at the upper end of the mounting frame 104, and a ventilation component is fixedly installed on the side wall of the boiler body 101;

[0031] A shaking unit 200, the shaking unit 200 includes a driving motor 201 and two connecting plates 204. The driving motor 201 is fixedly connected to the side wall of the boiler body 101. The output end of the driving motor 201 penetrates through the side wall of the boiler body 101 and is fixedly connected to a rotating rod 202. Two cams 203 are fixedly sleeved on the rotating rod 202. Both connecting plates 204 are fixedly connected to the lower end of the mounting frame 104. Limiting plates 205 are fixedly connected to the opposite sides of the two connecting plates 204. A vertical rod 206 is slidably inserted through the inner wall of each limiting plate 205. A top plate 207 is fixedly connected to the upper end of each vertical rod 206. A rotating wheel assembly 209 is fixedly installed at the lower end of each vertical rod 206. A return spring 208 is sleeved on each vertical rod 206.

[0032] The driving motor 201, the rotating rod 202 and the cam 203 are arranged to drive the rotating wheel assembly 209 to move upward and compress the return spring 208. The return spring 208 can reset the rotating wheel assembly 209. Therefore, the cam 203 and the return spring 208 can drive the rotating wheel assembly 209 to move up and down reciprocally. Due to the gravity of the rotating wheel assembly 209, the vertical rod 206, the top plate 207 and the boiler grate 105, the boiler grate 105 will shake up and down, causing the ashes and residues generated after combustion to fall from the boiler grate 105, removing the accumulations in time, avoiding its blockage of the grate and hindering air circulation, so as to prevent negative impacts on the combustion efficiency of the fuel.

[0033] Each group of the rotating wheel assemblies 209 includes a fixed frame and a rolling wheel. Each fixed frame is fixedly connected to the vertical rod 206. A rotating shaft is fixedly inserted through the center of each rolling wheel. Both ends of each rotating shaft are rotatably connected to the inner side wall of the fixed frame. The lower end of each rolling wheel abuts against the upper end of the cam 203, and the cam 203 is used to push the rotating wheel assembly 209 to move upward.

[0034] The ventilation assembly includes a fixed plate 102, which is fixedly connected to the side wall of the boiler body 101. A blower 103 is fixedly connected to the upper end of the fixed plate 102. The output end of the blower 103 communicates with the inside of the combustion chamber. Through the blower 103, air can be slowly and evenly ventilated into the boiler body 101.

[0035] A controller 106 is fixedly installed on the side wall of the boiler body 101, and a display screen is fixedly connected to the side wall of the controller 106.

[0036] A feed inlet and a discharge outlet are fixedly connected to the side wall of the boiler body 101. Pipe caps are installed at one ends of the feed inlet and the discharge outlet. Solid fuel is added into the boiler body 101 through the feed inlet.

[0037] Both ends of multiple return springs 208 are respectively fixedly connected to a limit plate 205 and one end of the fixed frame. The upper ends of multiple top plates 207 abut against the lower end of the boiler grate 105. The return spring 208 can reset the rotating wheel assembly 209.

[0038] Working principle: When the boiler grate 105 is blocked, the driving motor 201 is started. The output end of the driving motor drives the rotating rod 202 to rotate at a constant speed. The rotating rod 202 drives the cam 203 to rotate. The cam 203 drives the rotating wheel assembly 209 to move upward and compress the return spring 208. The return spring 208 can reset the rotating wheel assembly 209. Therefore, the arrangement of the cam 203 and the return spring 208 drives the rotating wheel assembly 209 to move up and down reciprocally. The rotating wheel assembly 209 drives the vertical rod 206 to move up and down. The vertical rod 206 and the top plate 207 push the boiler grate 105 to move upward. Combining with the gravity of the boiler grate 105 itself, the boiler grate 105 can be made to vibrate up and down, so that the ashes and residues generated after combustion fall from the boiler grate 105, and the accumulations are removed in time to avoid blocking the grate and hindering air circulation, thereby preventing negative impacts on the combustion efficiency of the fuel.
