Description

Technical Field

[0001] This utility model relates to the field of fuel feeding technology, and in particular to a biomass boiler feeder. Background Technology

[0002] Biomass boiler feeders are mainly used to transport biomass fuels (such as wood chips, straw, rice husks, etc.) into the biomass boiler for combustion, ensuring a continuous and stable supply of biomass fuel to the boiler to maintain normal combustion operation and generate heat energy for power generation, heating or other industrial production purposes.

[0003] In the field of biomass boiler feeding technology, traditional feeders have many shortcomings due to their simple structural design and lack of flexibility. They are difficult to accurately adapt to the diverse feeding needs of different biomass boilers. Their limited angle adjustment capability makes it difficult to connect to the feed inlet in complex installation environments, affecting production efficiency. Furthermore, the height adjustment lacks a precise and stable control mechanism, which cannot meet different height requirements. This can easily lead to inaccurate material conveying height, causing problems such as material spillage and accumulation, wasting resources and interfering with the normal operation of the boiler.

[0004] This utility model uses a power source to drive the core conveying component to rotate, allowing materials to enter a closed channel from a specific inlet, and enabling multi-angle adjustment of the core conveying component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biomass boiler feeder, comprising a working base, two rotating seats symmetrically fixedly connected to the top of the working base, a first rotating shaft fixedly inserted into the opposite sides of the two rotating seats, a fixed seat rotatably connected to the outer surface of the first rotating shaft, two first fixed discs symmetrically fixedly connected to the top of the working base, a sleeve fixedly connected to the top of each first fixed disc, a toothed column movably inserted inside each sleeve, a first gear meshing on the outer wall of each toothed column, a third rotating shaft fixedly connected inside the first gear, a second gear fixedly connected to the outer surface of the third rotating shaft, a rack meshing on the outer wall of the second gear, an electric push rod fixedly connected to the top of the working base, and the output end of the electric push rod fixedly connected to one end of a motor, a second fixed disc fixedly connected to the top of the working base, a sliding groove fixedly connected to the top of the second fixed disc, and the outer surface of the rack slidingly fitting against the inner wall of the sliding groove.

[0008] Preferably, one end of the transmission auger is rotatably connected to a dust cover, and the outer surface of the dust cover is fixedly connected to one end of the conveying chamber.

[0009] Preferably, the outer surface of the conveying chamber is fixedly connected to a discharge port, and the interior of each of the two toothed columns is rotatably connected to a second rotating shaft.

[0010] Preferably, the opposite sides of the two second rotating shafts are fixedly connected to the lifting pallet, and the top of the lifting pallet is fixedly connected to the outer wall of the conveying chamber.

[0011] Preferably, the top of the working base is stacked and fixedly connected with two support columns, and the outer surface of the third rotating shaft is movably inserted into the interior of the support columns.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during equipment operation, the power source drives the core conveying component to rotate, causing materials to enter the enclosed channel from a specific inlet.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] As attached Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: a biomass boiler feeder structure, including a working base 1, two rotating seats 11 symmetrically fixedly connected to the top of the working base 1, a first rotating shaft 13 fixedly inserted into the opposite side of the two rotating seats 11, a fixed seat 12 rotatably connected to the outer surface of the first rotating shaft 13, two first fixed discs 14 symmetrically fixedly connected to the top of the working base 1, a sleeve 15 fixedly connected to the top of each first fixed disc 14, a toothed column 23 movably inserted inside each sleeve 15, a first gear 25 meshing with the outer wall of each toothed column 23, a third rotating shaft 26 fixedly connected inside the first gear 25, a second gear 27 fixedly connected to the outer surface of the third rotating shaft 26, and a rack 22 meshing with the outer wall of the second gear 27. An electric push rod 21 is fixedly connected to the top of the working base 1, and the output end of the electric push rod 21 is fixedly connected to one end of the motor 2. A second fixed plate 16 is fixedly connected to the top of the working base 1, and a sliding groove 18 is fixedly connected to the top of the second fixed plate 16. The outer surface of the rack 22 slides against the inner wall of the sliding groove 18. The working base provides stable support and installation foundation for the feeder. All components work together to achieve angle adjustment, height adjustment and material conveying. The motor drives the transmission auger to push the material, the conveying bin ensures material conveying, the feed pipe ensures convenient feeding, and the dust cover protects the environment and equipment. This makes the feeder operate efficiently, stably, safely and universally, and adaptably. It can feed accurately, reduce failures and losses, extend equipment life, and improve the level of intelligence and ease of operation.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a motor 2 is fixedly connected to the top of the fixed base 12, and a transmission auger 28 is fixedly connected to the output end of the motor 2. A conveying chamber 3 is fitted on the outer surface of the transmission auger 28. Driven by the motor, the transmission auger 28 conveys materials in the conveying chamber 3 using the principle of spiral propulsion. Its spiral structure can push materials evenly, avoid blockage, adapt to a variety of biomass materials, and has strong versatility. It also fits tightly with the conveying chamber, reducing material leakage, improving feeding accuracy and efficiency, and ensuring that materials can be accurately conveyed into the biomass boiler. At the same time, the conveying chamber 3 provides a closed channel for materials, preventing scattering, keeping the environment clean, and also buffering material collisions, reducing breakage and loss, reducing safety hazards, and making the feeding operation safe and efficient.

[0024] like Figure 1 and Figure 2 As shown, the outer surface of the conveying chamber 3 is connected to the feed pipe 31, which provides a convenient entrance for materials to enter the conveying chamber 3 and facilitates connection with the upstream material supply system. The shape, length and position can be flexibly designed according to the actual production layout and material supply method to ensure that materials can enter the conveying chamber 3 at a suitable angle and speed.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a dust cover 32 is rotatably connected to one end of the transmission auger 28, and the outer surface of the dust cover 32 is fixedly connected to one end of the conveying chamber 3. The dust cover 32 effectively prevents the dust generated during the conveying process of the transmission auger 28 from being blown out, protects the cleanliness of the working environment, reduces the harm of dust to the health of operators, and at the same time prevents dust from accumulating around the equipment, reducing the safety hazards caused by dust accumulation (such as dust explosions).

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a discharge port 33 is fixedly connected to the outer surface of the conveying chamber 3. The two toothed columns 23 are rotatably connected to a second rotating shaft 24. The discharge port 33 serves as the final outlet for material conveying. Its position and shape can be precisely designed according to the feed port requirements of the biomass boiler. This ensures that the material falls accurately into the boiler, reduces material spillage and waste, and improves the accuracy and efficiency of feeding.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the opposite sides of the two second rotating shafts 24 are fixedly connected to the lifting tray 29, and the top of the lifting tray 29 is fixedly connected to the outer wall of the conveying chamber 3. This fixed connection ensures a tight fit between the lifting tray 29 and the conveying chamber 3, enabling the lifting tray 29 to effectively transmit the lifting force from the toothed column 23 to the conveying chamber 3, thereby achieving precise height adjustment of the conveying chamber 3. The stability of the fixed connection can prevent loosening or displacement during the lifting of the conveying chamber 3, ensuring the normal operation of the feeder, improving the reliability and safety of the equipment, and enabling materials to be smoothly conveyed and fed in a stable environment of the conveying chamber 3.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the top of the working base 1 is fixedly connected to two support columns 17. The outer surface of the third rotating shaft 26 is movably inserted into the interior of the support columns 17. The support columns 17 provide stable support and guidance for the third rotating shaft 26, ensuring the straightness and stability of the third rotating shaft 26 during rotation. It can withstand the various forces generated by the third rotating shaft 26 and its connected gears during operation, preventing the third rotating shaft 26 from bending or deviating due to uneven force, thereby ensuring the normal operation of the entire gear transmission system. The presence of the support columns 17 enhances the rigidity and stability of the equipment structure, reduces failures caused by component shaking or displacement, improves the overall reliability and durability of the feeder, and enables the equipment to maintain good working performance during long-term operation.

[0029] Working principle: Material enters the conveying chamber 3 through the feed pipe 31. The conveying chamber 3 serves as the material conveying channel, preparing for the subsequent delivery of material to a designated location. The motor 2, fixedly connected to the fixed base 12, starts, and the output end of the motor 2 drives the transmission auger 28 to rotate. The transmission auger 28 rotates inside the conveying chamber 3, using the principle of spiral propulsion to push the material entering the conveying chamber 3 to move along the conveying chamber 3 in a specific direction, thereby realizing the material conveying function. The electric push rod 21, fixedly connected to the top of the working base 1, works. The output end of the electric push rod 21 is fixedly connected to one end of the motor 2. Its extension and retraction can drive the motor 2 and the entire conveying structure (including the conveying chamber 3 and other components) connected to it to move up and down within a certain range, realizing height adjustment. When the electric push rod 21 moves, it drives the motor 2 to move and also affects the relevant transmission components. Specifically, the toothed column 23 is inserted into the sleeve 15 and can move. The toothed column 23 meshes with the first gear 25. The first gear 25 is connected to the second gear through the third rotating shaft 26. Gear 27 is fixedly connected, and the second gear 27 meshes with rack 22. The outer surface of rack 22 slides against the inner wall of sliding groove 18 on the second fixed plate 16. Driven by electric actuator 21, this series of gears, pinions, racks and other components work together to realize the transmission and conversion of force, ensuring that the conveying chamber 3 can be smoothly adjusted in height. At the same time, the second rotating shaft 24, which is rotatably connected inside the two pinions 23, is fixedly connected to the lifting tray 29 on its opposite side. The lifting tray 29 is fixedly connected to the outer wall of the conveying chamber 3, further assisting and stabilizing the height adjustment action of the conveying chamber 3, ensuring that the entire conveying structure can stably change its height position to adapt to different biomass boiler feeding height requirements. A section of the transmission auger 28 is rotatably connected to a dust cover 32, and the outer surface of the dust cover 32 is fixedly connected to one end of the conveying chamber 3. During the material conveying process, the dust cover 32 can prevent dust generated during the conveying process from being blown out, playing a dust prevention role and making the working environment relatively clean.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
