Description

Technical Field

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

[0002] Biomass boiler is a type of boiler with a higher utilization rate. It is a boiler that uses biomass pellets as fuel. Biomass pellet fuel is a granular fuel made from discarded crops such as straw, rice stalks, wood chips and peanut shells through processes such as crushing, mixing, extrusion and drying. It is divided into several types and its function is to directly obtain heat energy or convert heat energy into electrical energy.

[0003] When the existing biomass boiler is burning, it is necessary to put the biomass fuel into the boiler, and it is very important to ensure the uniform distribution and complete combustion of the fuel. Biomass fuels, such as wood chips, straw, rice husks, etc., are easy to accumulate due to their natural properties, resulting in a significant decrease in the combustion efficiency of the biomass fuel. The problem of the internal biomass fuel not being able to be fully burned may also increase the emission of carbon monoxide, unburned carbon particles and other pollutants in the flue gas, affecting the environmental quality.

[0004] In view of this, a biomass boiler capable of keeping the accumulated biomass in a loose state is designed to solve the above problems. Utility Model Content

[0007] Furthermore, it also includes an electric slide rail, a protective cover plate, a fixed rod and a connecting plate. The electric slide rail is installed on the support base, and the fixed rod is fixedly connected to the combustion chamber. A plurality of connecting plates are slidingly arranged on the electric slide rail and the fixed rod, and the connecting plates are all fixedly connected with protective covers, and the protective covers are directly opposite to the material opening.

[0008] Furthermore, it also includes a second support frame, a support platform and filter cotton. The second support frame is sleeved on the air outlet, the support platform is fixedly connected to the second support frame, and the filter cotton is arranged on the support platform.

[0011] Furthermore, it also includes a protective shell, which is fixedly connected to one side of the combustion chamber close to the motor, and the protective shell is located on the periphery of the motor.

[0012] Compared with the prior art, the utility model has the following advantages: 1.

DETAILED DESCRIPTION

[0023] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0024] Example 1: A biomass boiler, see Figure 1-Figure 5As shown, it includes a support base 1, a combustion bin 2, a placement table 3, an igniter 4, a heat exchange bin 5, a first support frame 6, a support frame 7, a heat exchange tube 8 and a vibration component. The combustion bin 2 is installed on the support base 1, and a material port 201 is opened on one side of the combustion bin 2. The heat exchange bin 5 is installed on the top of the combustion bin 2. An air outlet 501 is opened on the top of the heat exchange bin 5. An isolation net 2301 is fixedly connected to the top of the air outlet 501 by welding. The first support frame 6 is fixedly connected to the first support frame 6 by welding. Heat exchange tubes 8 are installed on the support frame 7, and the heat exchange tubes 8 are connected and communicated with the heat exchange bin 5. Multiple igniters 4 are fixedly connected to the lower part of the combustion bin 2 by welding. The lower part of the combustion bin 2 is slidably connected to the placement table 3. It also includes the placement table 3, a fluctuation plate 301, and a fluctuation rod 302, a first connecting rod 303, a motor 304, a cam 305, a first guide rod 306, a first elastic member 307 and a protective shell 24, a motor 304 is installed on one side of the combustion chamber 2, a cam 305 is fixedly connected to the output shaft of the motor 304 by welding, a protective shell 24 is fixedly connected to the side of the combustion chamber 2 close to the motor 304 by welding, and the protective shell 24 is located at the periphery of the motor 304, a first connecting rod 303 is slidably provided on the same side of the combustion chamber 2 as the motor 304, a fluctuating plate 301 is provided on the first connecting rod 303, a first guide rod 306 is slidably provided on the fluctuating plate 301, a first elastic member 307 is sleeved between the first guide rod 306 and the fluctuating plate 301, a placing table 3 is fixedly connected to the fluctuating plate 301 by welding, and the fluctuating plate 301 is in contact with the fluctuating rod 302.

[0025] See also Figure 7 As shown, it also includes a second support frame 13 , a support platform 14 and filter cotton 15 . The second support frame 13 is sleeved on the air outlet 501 . The support platform 14 is fixedly connected to the second support frame 13 . The filter cotton 15 is arranged on the support platform 14 .

[0026] When the device is needed, add biomass fuel into the combustion chamber 2, and ignite the biomass fuel by spraying flames through the igniter 4. When the heat generated by the biomass combustion passes through the heat exchange chamber 5, it contacts the heat exchange tube 8, and the heat is extracted through the heat exchange tube 8. The extracted heat is directly used to boil water or used elsewhere, while other gases are discharged through the gas outlet 501. When the gas is discharged, the filter cotton 15 filters the gas, filtering the irritating gas and the tiny particles carried in the gas. At the same time, the motor 304 can be started to make the cam 305 contact the first connecting rod 303, thereby pushing the first connecting rod 303 to move the fluctuating plate 301 to one side. When the cam 30 When the first connecting rod 303 is no longer in contact with the first connecting rod 303, the first elastic member 307 causes the fluctuating plate 301 and the placing platform 3 to reset, so that the placing platform 3 and the fluctuating plate 301 are in contact with each other and vibrate continuously. After the first connecting rod 303 is reset, the first connecting rod 303 and the placing platform 3 are reset under the gravity of the biomass fuel, so that the biomass fuel on the placing platform 3 remains in a loose state, ensuring that the fuel layer is evenly distributed, preventing the biomass fuel from piling up, ensuring the uniformity and air permeability of the fuel layer, thereby improving the combustion efficiency, reducing the incompletely burned residues, and reducing the pollutant emissions. When the biomass fuel is burned, the residues after the biomass is burned in the combustion chamber 2 are cleaned out.

[0027] Example 2: See Figure 6 As shown, it also includes an electric slide rail 9, a protective cover plate 11, a fixed rod 10 and a connecting plate 12. The electric slide rail 9 is installed on the support base 1, and the fixed rod 10 is fixedly connected to the combustion chamber 2 by welding. A plurality of connecting plates 12 are slidably arranged on the electric slide rail 9 and the fixed rod 10, and the protective cover plates 11 are fixedly connected to the connecting plates 12 by welding, and the protective cover plates 11 are directly opposite to the material port 201.

[0028] In order to prevent the flame generated by biomass combustion from spraying to the outside, the electric slide rail 9 is first started, and then the connecting plate 12 on the electric slide rail 9 moves to drive the protective cover plate 11 to move to both sides, the material port 201 is opened, and biomass fuel is added. When the biomass fuel is burned, the protective cover plate 11 is closed to isolate the flame generated by the biomass combustion.

[0029] See also Figure 8As shown, it also includes a mounting frame 16, a screw 17, a second guide rod 18, a pushing frame 19, a limiting frame 20, a second connecting rod 21, a limiting disk 22 and a second elastic member 23. The mounting frame 16 is fixedly connected to the side of the combustion bin 2 away from the material port 201, and the mounting frame 16 is rotatably connected to the screw 17. The mounting frame 16 is also fixedly connected to the second guide rod 18. The pushing frame 19 is threadedly connected to the screw 17, and the pushing frame 19 is slidably arranged on the second guide rod 18. The limiting frames 20 are fixedly connected to both sides of the combustion bin 2, and the second connecting rod 21 is slidably arranged on the combustion bin 2 and the limiting frame 20. The limiting disk 22 is fixedly connected between the second connecting rods 21 on both sides, and a second elastic member 23 is sleeved between the limiting frame 20 and the second connecting rod 21.

[0030] When it is necessary to limit the height of the biomass, the biomass fuel is added into the combustion chamber 2, and after the protective cover 11 is closed, the screw 17 is rotated, and the push frame 19 moves accordingly. When the push frame 19 moves, the second connecting rod 21 is squeezed to make the limit plate 22 move downward, and the limit frame 20 plays a guiding role, and the second elastic member 23 is deformed, and the limit plate 22 moves downward to press down the excessively high biomass fuel. After pressing down, the screw 17 is rotated in the opposite direction so that the push frame 19 no longer squeezes the second connecting rod 21, and the second elastic member 23 returns to its original state, so that the second connecting rod 21 is reset and drives the limit plate 22 to reset, thereby achieving the effect of limiting the height of the biomass fuel.

[0031] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention.
