[0002] As a clean and renewable energy source, the development and utilization of biomass energy has attracted widespread attention. Biomass combustion equipment can convert biomass into thermal energy. However, existing biomass combustion equipment still has many problems in practical application. Traditional biomass combustion equipment relies solely on simple feeding devices and is unable to perform targeted pre-processing operations such as crushing and cutting on biomass raw materials. It is difficult to process the raw materials to a particle size suitable for combustion, which not only leads to low combustion efficiency, but also easily causes coking, blockage and other faults inside the equipment, seriously affecting the stable operation and service life of the equipment.

[0013] The present invention provides a biomass combustion device with a pretreatment mechanism. It has the following beneficial effects: 1. The biomass combustion equipment with a pre-treatment mechanism, through the setting of the pre-treatment mechanism, the motor drives the transmission shaft to rotate, driving the crushing part 1, the cutting part and the feeding part to operate. The biomass raw material enters from the feed hopper, and is first initially crushed by the rotating ring block in the crushing part 1 in cooperation with the crushing part 2. The feed hole on the rotating ring block brings the raw material in, and the crushing blocks 1 and 2 squeeze each other to crush the raw material. Then the cutting blades of the cutting part further cut the initially crushed raw material, and finally the spiral feed piece of the feeding part feeds the processed raw material into the combustion chamber through the discharge pipe. The pre-treatment mechanism crushes and cuts the biomass raw material, processes the raw material into a suitable size, increases the contact area between the raw material and oxygen, enables the raw material to be fully burned in the combustion chamber, improves combustion efficiency, reduces the emission of pollutants caused by incomplete combustion, and ensures smooth raw material transportation to avoid blockage.

[0014] Second, this biomass combustion equipment with a pre-treatment mechanism utilizes a feed mechanism. After the raw materials are poured into the hopper, a guide plate guides them downward, preventing splashing during the crushing process. The annular baffle of the crushing element 2 screens the raw materials, allowing small particles to pass through the sieve holes while larger particles remain on the plate for further crushing. The feed mechanism provides initial guidance for the raw materials entering the pre-treatment mechanism, assisting in the crushing process and improving pre-treatment efficiency.

[0015] 3. The biomass combustion equipment with a pretreatment mechanism is equipped with a stabilizing frame, which connects the combustion chamber and the feed pipe of the pretreatment mechanism. During the operation of the equipment, the stabilizing frame withstands the vibration and force generated by the operation of the pretreatment mechanism and disperses them to the combustion chamber and the base, thereby enhancing the stability of the connection between the combustion chamber and the pretreatment mechanism, preventing the pretreatment mechanism from being displaced or loosened due to vibration, ensuring the stability of the overall structure of the equipment, and extending the service life of the equipment.

[0016] 4. The biomass combustion equipment with a pretreatment mechanism, through the setting of the fan, sends external air into the combustion chamber through the air outlet, continuously replenishes oxygen during the combustion process, provides sufficient oxygen for the combustion of biomass in the combustion chamber, promotes the full combustion of biomass, improves the completeness of combustion, improves combustion efficiency, enables the equipment to output more heat energy, and at the same time reduces the incomplete combustion caused by lack of oxygen, and reduces the generation of pollutants such as black smoke and carbon monoxide.

[0017] 5. The biomass combustion equipment with a pretreatment mechanism, through the setting of the feeding piece, the spiral feeding piece will transport the biomass raw materials that have been crushed and cut downward along the feeding pipe. The guide trough facilitates the transportation of the material, ensuring that the material can smoothly pass through the discharge pipe into the combustion chamber. When the output end of the motor rotates in the opposite direction, the spiral feeding piece rotates in the opposite direction to prevent the material from being transported downward, so that the material continues to be cut in the cutting piece area, thereby improving the subsequent combustion efficiency.

The output end of the motor 32 drives the transmission shaft 33 to rotate at a high speed, thereby driving the crushing part 34, the cutting part 35 and the feeding part 36. The crushing element 34 crushes the biomass raw material during the rotation process, breaking the larger block of raw material into smaller particles for subsequent cutting and combustion. The cutting element 35 rotates at high speed under the drive shaft 33, and further cuts the biomass raw material after the initial crushing by the crushing element 34, cutting the raw material into smaller sizes so that it can fully contact with oxygen during combustion, thereby improving combustion efficiency.

The guide groove 362 facilitates the transportation of the material and ensures that the material can smoothly pass through the discharge pipe 37 into the combustion chamber 2.

[0023] The third embodiment, based on the first and second embodiments, see Figures 8 to 10 As shown, the feeding mechanism 4 includes a feed hopper 41, which is fixedly mounted on the top of the feed pipe 31. The feed hopper 41 is convenient for the operator to pour the raw materials. A material guide 42 and a second crushing member 43 are fixedly mounted on the inner wall of the feed hopper 41. The material guide 42 is arranged just above the first crushing member 34. The material guide 42 can guide the biomass raw materials poured into the feed hopper 41 to the first crushing member 34 for crushing. The second crushing member 43 is arranged just below the first crushing member 34. The first crushing member 34 and the second crushing member 43 cooperate with each other to crush the raw materials. The side of the rotating ring block 344 is pressed and fitted with the inner wall of the hopper 41, and the crushing piece 2 43 is pressed and fitted with the rotating ring block 344 and the crushing piece 1 347; The material guide member 42 includes a second rotating block 421. A material guide plate 422 is fixedly mounted on the outer surface of the second rotating block 421. An arc-shaped fixing plate 423 is fixedly mounted on the other end of the material guide plate 422. The arc-shaped fixing plate 423 is fixedly mounted on the inner wall of the feed hopper 41. A bearing 424 is fixedly mounted on the axis of the bottom of the second rotating block 421. The top end of the transmission shaft 33 is rotatably mounted on the inner side surface of the bearing 424. The bearing 424 ensures that the transmission shaft 33 can rotate stably. There are eight guide plates 422 , and the eight guide plates 422 are evenly distributed along the axis of the second rotating block 421 . The guide plates 422 are inclined and can guide the biomass raw materials poured into the hopper 41 to the crushing area below and prevent the materials from splashing during the crushing process. The second crushing component 43 includes an annular baffle plate 431, which is fixedly installed on the inner wall of the hopper 41. Screening holes 432 are provided on the surface of the annular baffle plate 431. The screening holes 432 are used to screen the biomass raw materials. Smaller particles of raw materials can directly pass through the screening holes 432 and enter the lower part for subsequent processing. Larger particles remain on the annular baffle plate 431 to continue crushing. The annular baffle plate 431 is squeezed and adapted to the bottom of the rotating ring block 344. A conical ring disk 433 is fixedly installed on the inner side of the annular baffle plate 431. A crushing block 2 434 is fixedly installed on the upper surface of the conical ring disk 433. The crushing block 2 434 is squeezed and adapted to the crushing block 1 347.

[0024] During use, the operator pours the biomass raw materials into the hopper 41, and the inclined guide plate 422 guides the raw materials poured into the hopper 41 downward, so that the raw materials can enter the subsequent processing link more smoothly, while preventing the materials from splashing during subsequent crushing; During the falling process of the raw materials, the rotating ring block 344 rotates at a high speed driven by the motor 32, and its side surface is squeezed and adapted to the inner wall of the feed hopper 41. The five feed holes 345 evenly distributed on the surface of the rotating ring block 344 will bring the raw materials into the rotating ring block 344. During the rotation process, the crushing block 1 347 on the lower surface of the rotating ring block 344 and the crushing block 2 434 on the upper surface of the conical ring disk 433 squeeze each other to perform preliminary crushing of the larger particles of raw materials. The screening holes 432 on the surface of the annular baffle plate 431 will screen the raw materials. After crushing, the smaller particles of raw materials fall directly through the screening holes 432, while the larger particles of raw materials remain on the annular baffle plate 431 and continue to be crushed. After the initial crushing and screening, the raw materials continue to fall to the cutting member 35. The five cutting blades 352 evenly distributed on the outer surface of the cone seat 351 rotate at high speed driven by the transmission shaft 33, further cutting the raw materials into smaller sizes for subsequent full combustion. After being crushed and cut, the raw materials are transported by the feeding member 36. The spiral feeding piece 361 rotates along the transmission shaft 33, and the raw materials are transported downward along the feeding pipe 31. The guide groove 362 on the surface of the spiral feeding piece helps to directional convey the raw materials and prevent blockage. The raw materials enter the combustion chamber 2 through the discharge pipe 37. When the raw materials enter the combustion chamber 2, the operator activates the igniter inside the combustion chamber 2 through the control panel 12 to ignite the biomass raw materials. At the same time, the fan 6 starts to work, and its air outlet end blows air into the combustion chamber 2 to provide sufficient oxygen for combustion, so that the raw materials are fully burned. The high-temperature flame generated by the combustion is ejected through the burner 8 to heat other equipment or provide heat energy; During the combustion process, the operator can observe the combustion conditions inside the combustion chamber 2 through the fire viewing port 7, including the color, shape and intensity of the flame, and adjust the parameters such as the speed of the motor 32 and the air volume of the fan 6 through the control panel 12 according to the observation results to ensure that the combustion process is stable and efficient. When the ash produced by the combustion accumulates to a certain extent at the bottom of the combustion chamber 2, the operator can open the sealing door 11 on the outer surface of the ash cleaning port 10 to clean the ash. After cleaning, close the sealing door 11 to maintain the normal working environment of the combustion chamber 2.
