Description

Technical Field

[0001] This utility model relates to the field of fuel boiler technology, specifically a biomass fuel boiler with automatic ash removal function. Background Technology

[0002] A biomass fuel boiler is a device used to burn biomass. It can fully utilize wood, straw, wood chips, etc. to burn, and convert the high-temperature heat energy generated by combustion into clean energy. Unlike traditional coal boilers, using biomass fuel boilers can avoid excessive coal resource development and combustion, reduce pollution to the environment, and help reduce environmental damage.

[0003] Publication number CN222352348U discloses a horizontal biomass fuel boiler. This patent uses a pushing mechanism to control two pushing plates to push accumulated ash into a discharge trough. The ash falls into a collection cart for collection. After all the water in the dust removal chamber is drained, the chamber door is opened to clean the sediment. The operation is simple and convenient, and effective cleaning can be achieved without extensive disassembly of the device, reducing manual labor intensity, saving time and effort, and improving work efficiency. However, this patent still has the following problems in actual use:

[0004] The ash is pushed into the discharge chute by two pusher plates controlled by the pushing mechanism. The ash falls into the collection vehicle for collection. However, in actual use, biomass fuel (such as straw, wood chips, etc.) contains a lot of ash and unburned particles. When the fuel accumulates and fails to burn completely, the ash produced after combustion is easy to accumulate in the combustion chamber, making it difficult to discharge the ash after combustion. If the combustion ash cannot be completely discharged, it will easily affect the subsequent combustion efficiency.

[0005] A biomass fuel boiler with automatic ash removal function is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a biomass fuel boiler with automatic ash removal function to solve the problem mentioned in the background art. Currently, the ash is pushed into the discharge chute by two pusher plates controlled by the pusher mechanism, and the ash falls into the collection vehicle for collection. However, in actual use, biomass fuel (such as straw, wood chips, etc.) itself contains a lot of dust and unburned particles. When a lot of fuel is piled up and not fully burned, the ash produced after combustion is easy to accumulate in the combustion chamber, making it difficult to discharge the ash of subsequent combustion. If the combustion ash cannot be completely discharged, it will easily affect the subsequent combustion efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a biomass fuel boiler with automatic ash removal function, comprising a boiler body;

[0008] The boiler body has a combustion chamber fixedly installed inside, and an ash discharge pipe is connected through the bottom of the boiler body. The ash discharge pipe is also connected through the boiler body, and a valve is installed inside the ash discharge pipe.

[0009] Also includes:

[0010] A feed pipe is connected through the top of the boiler body, and a filter screen is fixedly installed inside the lower part of the combustion chamber. A cleaning component is also provided inside the lower part and on one side of the boiler body.

[0011] The cleaning component includes a servo motor fixedly installed on the lower side of the outer side of the boiler body, and a rotating block is fixedly installed on the output end of the servo motor. A movable plate is slidably connected to the lower interior of the boiler body, and the movable plate is slidably connected to the combustion chamber.

[0012] One end of the movable plate is fixedly mounted with an arc-shaped block, and an annular groove is provided on the outer side of the rotating block, and the arc-shaped block is slidably connected to the annular groove.

[0013] Preferably, two sets of fixing blocks are symmetrically installed on the top of the movable plate, and a rotating frame is hinged between the two fixing blocks in each set, and a movable frame is fitted on the outer side of the rotating frame.

[0014] Preferably, the movable frame is slidably connected to the rotating frame, and both outer sides of the two movable frames are rotatably connected to support frames, and the support frames are fixedly connected to the combustion chamber.

[0015] Preferably, a limiting frame is fixedly installed at the lower interior of the combustion chamber, and a movable rod is slidably connected inside the limiting frame.

[0016] Preferably, a V-shaped frame is fixedly installed at the bottom of the movable rod, and the upper two sides of the V-shaped frame are arc-shaped surfaces, while the lower two sides of the V-shaped frame are located on a plane.

[0017] Preferably, a mounting plate is fixedly installed on the top of the movable rod, and mounting brackets are symmetrically installed on the top of the mounting plate, with a column fixedly installed between the two mounting brackets.

[0018] Preferably, a guide block is fixedly installed at the bottom of the movable plate above the mounting plate, and a movable groove is opened through one side of the guide block, and the column rod is slidably connected to the movable groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this biomass fuel boiler with automatic ash removal function allows the filter screen to be tapped when the ash after combustion in the combustion chamber is discharged, so that the ash after combustion can be discharged through the filter screen. It can automatically clean the filter screen to avoid clogging, thus improving its practicality. The specific details are as follows:

[0020] 1. Fuel can be fed into the combustion chamber through the feeding pipe for combustion. The ash produced by combustion can enter the ash discharge pipe through the filter screen. If fuel accumulates on the filter screen, the servo motor can be started to drive the rotating block to rotate. The rotating block can rotate at an offset. While the rotating block rotates, the arc block can slide in the annular groove, which can drive the movable plate to move back and forth. During the movement of the movable plate, the rotating frame can rotate. During the rotation, the rotating frame can slide on the movable frame and drive the movable frame to rotate on the support frame. This allows the two rotating frames to intermittently beat the filter screen, causing the filter screen to vibrate continuously. The ash accumulated on the top of the filter screen is loosened, allowing the accumulated dust to pass through the filter screen. When the ash after combustion in the combustion chamber is discharged, the filter screen can be beaten, allowing the ash after combustion to pass through the filter screen and be discharged. The filter screen can be automatically cleaned to avoid clogging, improving its practicality.

[0021] 2. During ash removal, the ash can be discharged through the ash discharge pipe. The reciprocating movement of the movable plate causes the guide block to move back and forth. The movement of the guide block can drive the column rod to move through the movable slot, which in turn can pull the movable rod to move through the mounting frame. The reciprocating movement of the movable plate can drive the movable rod to move up and down, causing the V-shaped frame to move back and forth in the ash discharge pipe. When the V-shaped frame moves down, the lower plane can push the ash out. When the V-shaped frame moves up, the upper arc surface facilitates the passage of ash, thus preventing the ash from accumulating in the ash discharge pipe and improving practicality.

An arc-shaped block 204 is fixedly installed at one end of the movable plate 202, and an annular groove 205 is opened on the outer side of the rotating block 203. The arc-shaped block 204 is slidably connected to the annular groove 205, so that the ash after combustion can be discharged through the filter screen 104. The filter screen 104 can be automatically cleaned to avoid clogging, thus improving practicality.

[0031] Two sets of fixed blocks 206 are symmetrically installed on the top of the movable plate 202, and a rotating frame 207 is hinged between the two fixed blocks 206 in each set. A movable frame 208 is fitted on the outer side of the rotating frame 207, so that the movement of the movable plate 202 can drive the rotating frame 207 to move. The movable frame 208 is slidably connected to the rotating frame 207, and a support frame 209 is rotatably connected to both outer sides of the two movable frames 208. The support frame 209 is fixedly connected to the combustion chamber 101 to support the rotating frame 207. A limit frame 210 is fixedly installed at the bottom of the combustion chamber 101, and a movable rod 211 is slidably connected inside the limit frame 210 to support the movement of the movable rod 211. The bottom of the movable rod 211 is fixedly installed... The device is equipped with a V-shaped frame 212, with the upper two sides of the V-shaped frame 212 being arc-shaped and the lower two sides of the V-shaped frame 212 being flat, which can be used to unclog the ash discharge pipe 102.

[0032] Working principle: Before using this biomass fuel boiler with automatic ash removal function, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, fuel can be fed into the combustion chamber 101 through the feed pipe 103 for combustion. The ash produced by combustion can enter the ash discharge pipe 102 through the filter screen 104. If fuel accumulates on the filter screen 104, the servo motor 201 can be started to drive the rotating block 203 to rotate. The rotating block 203 can rotate in an offset manner. While the rotating block 203 rotates, the arc-shaped block 204 can slide in the annular groove 205, which can drive the movable plate 202 to move back and forth. During the movement of the movable plate 202, the rotating frame 207 can be driven to rotate. During the rotation of the rotating frame 207, it can... The rotating frame 207 can slide on the movable frame 208 and drive the movable frame 208 to rotate on the support frame 209, so that the two rotating frames 207 can intermittently tap the filter screen 104, causing the filter screen 104 to vibrate continuously. The ash accumulated on the top of the filter screen 104 is loosened, allowing the accumulated dust to pass through the filter screen 104. When the ash after combustion in the combustion chamber 101 is discharged, the filter screen 104 can be tapped, allowing the ash after combustion to pass through the filter screen 104 and be discharged. The filter screen 104 can be automatically cleaned to avoid clogging, thus improving its practicality.

[0033] During ash removal, ash can be discharged through the ash discharge pipe 102. The reciprocating movement of the movable plate 202 causes the guide block 213 to reciprocate. The movement of the guide block 213 can drive the column rod 216 to move through the movable groove 217, which in turn can pull the movable rod 211 to move through the mounting bracket 215. The reciprocating movement of the movable plate 202 can drive the movable rod 211 to move up and down, causing the V-shaped frame 212 to move back and forth in the ash discharge pipe 102. When the V-shaped frame 212 moves down, the lower plane can push the ash out. When the V-shaped frame 212 moves up, the upper arc surface facilitates the passage of ash, thereby preventing the ash from accumulating in the ash discharge pipe 102 and improving practicality.
