Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for biomass boilers, and in particular to a biomass bulk material feeding and cutting device. Background Technology

[0002] Biomass is characterized by its renewable organic matter derived from living organisms, such as agricultural and forestry waste (straw, rice husks, sawdust, branches, fruit shells), energy crops (swallowtail millet, miscanthus, sweet sorghum), organic waste (kitchen waste, livestock and poultry manure, sludge), and processing residues (oil pressing residue, sugarcane bagasse, wood processing scraps). These raw materials can often be used as energy sources in boilers. Compared to traditional coal, these materials are renewable, energy-saving, and environmentally friendly, making them an important part of my country's new energy strategy.

[0003] Biomass materials generally need to be processed into shapes to facilitate subsequent storage and improve combustion efficiency. Taking agricultural and forestry waste or energy crop processing as an example, when used as fuel, cutting is often required during processing. This not only facilitates cutting longer or larger materials into shorter pieces for subsequent crushing and shaping processes, but also allows for direct combustion after cutting. Cutting increases the surface area of ​​the biomass material, improving the oxygen contact area and thus increasing the combustion rate. While existing technologies exist for cutting or slicing biomass materials, traditional cutting equipment often uses rotary blades or guillotines because some biomass materials (straw, branches, etc.) have long structures and contain fibers. Rotary blades may produce fiber strips. While fiber entanglement is less likely to occur with guillotine cutters, the latter often requires additional equipment to secure the biomass material during cutting to prevent material splattering. For example, Chinese utility model patents CN218170643U and CN210210542U, both employing open-type cutting methods, not only wasteful but also posing safety hazards to equipment and surrounding personnel. Furthermore, existing cutting equipment often uses traditional conveyor belt structures, making it difficult to guide and centrally process materials, resulting in low processing efficiency and difficulty in recycling and reusing the cut waste, easily leading to resource waste.

[0004] Therefore, existing technologies need further improvement and enhancement. Utility Model Content

[0005] The purpose of this invention is to propose a biomass bulk material feeding and cutting device to solve the problems of poor cutting effect, low efficiency, low reliability, and difficulty in resource recycling in the existing cutting devices.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This application provides a biomass bulk material feeding and cutting device, which includes a conveying plate, an adjusting component, a cutting component, and a return component. The conveying plate has numerical sidewalls on its edge. The adjusting component and the cutting component are disposed on the conveying plate. The cutting component includes a frame-shaped cutter, a push plate, and an opening and closing gate. The push plate and the opening and closing gate are disposed opposite to each other. The adjusting component is disposed in front of the cutting component and includes a centrally located adjusting plate disposed on the left and right sides of the conveying plate. The return component is disposed at the opening and closing gate to recycle the cut waste material.

[0008] In a preferred embodiment of this application, the cutting assembly further includes a positioning frame, which includes a frame body and a mounting platform. A frame-shaped cutter is provided at the bottom of the mounting platform, the frame body is placed on both sides of the conveyor plate, and the mounting platform is movable based on the top of the frame body.

[0009] In a preferred embodiment of this application, a telescopic rod is provided between the frame-shaped cutter and the mounting platform, and a connecting plate is provided on the bottom wall of the mounting platform. The connecting plate is connected to the telescopic rod and is slidably connected to the bottom wall of the mounting platform.

[0010] In a preferred embodiment of this application, the reflux assembly includes a reflux channel and a recycling box disposed at the bottom of the reflux channel, with the reflux channel inlet connected to an opening and closing door.

[0011] In a preferred embodiment of this application, a mounting frame is provided at the position of the opening and closing door of the conveyor plate, the mounting frame is connected to the opening and closing door, and the opening and closing door moves vertically along the mounting frame.

[0012] In a preferred embodiment of this application, a telescopic rod is provided between the centering adjustment plate and the side wall of the conveying plate.

[0013] In a preferred embodiment of this application, the cutting assembly further includes a vibrating element disposed on the top of the frame-shaped cutter.

[0014] In a preferred embodiment of this application, the surface of the frame cutter is coated with a polytetrafluoroethylene anti-stick coating.

[0015] In a preferred embodiment of this application, a concentrator is provided on the surface of the conveyor plate. The concentrator is located behind the cutting assembly. There are two concentrators arranged opposite each other. The concentrator includes a guide belt and guide rollers disposed at both ends of the guide belt. The guide rollers and the guide belt are arranged vertically.

[0016] In a preferred embodiment of this application, the concentrator is further provided with a guide ramp, one end of which is connected to the side wall of the conveyor plate, and the other end is inclined toward the guide rollers, with a gap between the guide rollers and the side wall of the conveyor plate.

[0017] The technical solution provided by this utility model can include the following beneficial effects:

[0018] This invention provides a biomass bulk material feeding and cutting device. By setting an adjustment component before the cutting component, the transported raw materials are concentrated and gathered, improving cutting efficiency and facilitating subsequent cutting operations. The cutting component adopts a frame-type cutter structure. Compared with traditional rotary cutters or sheet-like vertical cutters, the frame-type cutter can enclose the material during cutting, which not only improves cutting efficiency but also avoids material splashing during the cutting process. Furthermore, for materials such as straw and branches, which are prone to fiber breakage after cutting, the vertical cutting process of the frame-type cutter in this application results in instantaneous fiber breakage rather than tensile tearing, reducing fiber adhesion. In addition, the return component in this application, in conjunction with a push plate and an opening and closing door, can collect waste generated during the cutting process, which can be recycled and reused as raw materials or for other uses, saving resources and reducing costs.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following is combined Figure 1 and Figure 2 This application provides a biomass bulk material feeding and cutting device, which includes a conveying plate 1, an adjusting component 2, a cutting component 3, and a return component 4. The conveying plate 1 has numerical sidewalls on its edge. The adjusting component 2 and the cutting component 3 are disposed on the conveying plate 1. The cutting component 3 includes a frame-shaped cutter 31, a push plate 32, and an opening and closing gate 33. The push plate 32 and the opening and closing gate 33 are disposed opposite to each other. The adjusting component 2 is disposed in front of the cutting component 3 and includes a central adjusting plate 21 disposed on the left and right sides of the conveying plate 1. The return component 4 is disposed at the opening and closing gate 33 to recycle the cut waste material.

[0028] Among them, such as Figure 1 As shown, the conveyor plate 1 has a common track or conveyor belt structure, with side walls on both sides to prevent transported materials from falling off. The return component 4 has a similar structure, also using a track or conveyor belt structure, to recycle the remaining waste material after cutting. The return component 4 can be guided to the recycling box 42 on one side for recycling, or it can be guided to the head of the conveyor plate 1 for direct mixing and re-transportation, thereby improving the recycling effect of raw materials and saving resources.

[0029] As a preferred embodiment of this application, such as Figure 2As shown, the cutting assembly 3 also includes a positioning frame, which includes a frame body 34 and a mounting platform 35. A frame-shaped cutter 31 is provided at the bottom of the mounting platform 35. The frame body 34 is placed on both sides of the conveyor plate 1, and the mounting platform 35 is movable based on the top of the frame body 34.

[0030] It is understandable that the frame 34 can adopt a vertical support structure, which makes it easy to designate the placement platform 35, thereby facilitating the driving of the frame-type cutter 31 to perform vertical cutting. A telescopic rod is provided between the frame-type cutter 31 and the placement platform 35. A connecting plate 36 is provided on the bottom wall of the placement platform 35. The connecting plate 36 is connected to the telescopic rod and is slidably connected to the bottom wall of the placement platform 35.

[0031] The telescopic rod can be an electric telescopic rod or a hydraulic telescopic rod structure to drive the frame-type cutter 31 to move. The side wall of the connecting plate 36 can be equipped with a drive motor. The top of the connecting plate 36 is embedded in the slide at the bottom of the mounting platform 35. The connecting plate 36 can be driven by the drive motor to move, thereby driving the telescopic rod to move laterally, which is convenient for adjusting the position.

[0032] The frame-type cutter 31 can be a square frame with a blade at the bottom for cutting biomass materials. Its width is no greater than the width of the conveyor plate 1, and its surface area can be adjusted by replacing different frame-type cutters 31 as needed. During cutting, the frame-type cutter 31 can cut the material in a closed manner as much as possible, avoiding the material splashing that occurs during direct cutting in existing technologies. This makes it more convenient to use and results in a more compact fuel mixture.

[0033] As a preferred embodiment of this application, such as Figure 2 As shown, the reflux assembly 4 includes a reflux channel 41 and a recycling box 42 disposed at the bottom of the reflux channel 41. The inlet of the reflux channel 41 is connected to the opening and closing door 33.

[0034] The conveyor plate 1 is positioned at the location of the opening and closing door 33 and is equipped with an installation frame 37. The installation frame 37 is connected to the opening and closing door 33, and the opening and closing door 33 moves vertically along the installation frame 37. The installation frame 37 has a sliding channel inside and a mounting position on its top. The mounting position is used to mount an electric pull rod, which can be connected to the opening and closing door 33 to drive the opening and closing door 33 to perform a vertical square movement.

[0035] Furthermore, a telescopic rod is provided between the centering adjustment plate 21 and the side wall of the conveying plate 1. The telescopic rod can be an electric telescopic rod, which drives the centering adjustment plate to push the biomass material towards the center of the conveying plate, so that the subsequent frame cutter 31 can frame the material as much as possible and cut it.

[0036] In a preferred embodiment, the cutting assembly 3 further includes a vibrating element 38, which can be an electric vibrating element 38 structure. The vibrating element 38 is disposed on the top of the frame-shaped cutter 31. After the cutting operation has been carried out for a period of time, the vibrating element 38 can drive the frame-shaped cutter 31 to resonate, thereby vibrating and dislodging the raw materials adhering to the inside of the frame-shaped cutter 31, which facilitates subsequent cutting operations and further recycling of resources.

[0037] Optionally, the surface of the frame cutter 31 is coated with a polytetrafluoroethylene non-stick coating, which can further reduce material adhesion and improve the performance.

[0038] As a preferred embodiment of this application, such as Figure 1 As shown, a concentrator 5 is provided on the surface of the conveyor plate 1. The concentrator 5 is located behind the cutting assembly 3. There are two concentrators 5 arranged opposite each other. The concentrator 5 includes a guide belt 52 and guide rollers 51 arranged at both ends of the guide belt 52. The guide rollers 51 and the guide belt 52 are arranged vertically.

[0039] The concentrator 5 is also equipped with a guide ramp 53. One end of the guide ramp 53 is connected to the side wall of the conveyor plate 1, and the other end is inclined towards the guide rollers 51. There is a gap between the guide rollers 51 and the side wall of the conveyor plate 1. It can be understood that after the material is concentrated by the adjustment component 2, it is cut by the frame cutter 31. After cutting, the material moves towards the guide belt 52 under the guidance of the guide ramp 53. Under the limit and drive of the guide belt 52, it is further conveyed to the rear. The double centering positioning ensures that the material moves smoothly.

[0040] Specifically, during use, the material moves along the conveyor plate 1 and is centered under the pushing limit of the adjusting component 2, continuously transported to the cutting component 3 at the rear. The frame-shaped cutter 31 moves from top to bottom to cut the material. After that, the material continues to be transported to the rear and is repositioned and centered again under the action of the concentrator 5 at the rear, ensuring the smooth operation of the material. The material remaining on the frame-shaped cutter 31 can be pushed to the opening and closing door 33 under the action of the push plate 32 and enter the return component 4 for recycling. This recycling process can be carried out after each cut or after working for a period of time, ensuring the recycling of resources.

[0041] Of course, this application should also include a control box structure to start, stop, and control the entire equipment. For the control section, a PLC or microcontroller program can be used to achieve automated operation and improve the level of intelligence. Regarding the selection of the program, similar control modules from the prior art can be used, and this application will not provide specific details.

[0042] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
