Description

Technical Field

[0001] This application relates to the field of fuel stove equipment, specifically a biomass fuel stove. Background Technology

[0002] Biomass fuels mainly come from agricultural and forestry waste, organic household waste, etc. As a key piece of equipment for the efficient utilization of biomass energy, the research and development and improvement of biomass fuel stoves are of great significance.

[0003] For example, the patent application number CN214468789U specifically discloses a biomass stove that facilitates feeding, including a box, motor, cylinder, rotary blades, a first vertical plate and a baffle, which can prevent waste from polluting the environment and endangering the health of users.

[0004] While the aforementioned patented biomass stove uses a baffle to push waste towards the opening and then into the cylinder through the feed pipe, relying on spiral blades to transport the waste, in actual use, there are several issues. First, gaps exist between the bottom of the baffle and the top of the partition, resulting in dust remaining on the surface of the partition and incomplete dust removal. Second, the ash scraping process relies on the coordinated operation of a motor, a geared motor, multiple sets of gears, and a complex linkage structure. If any component malfunctions, such as a motor failure or abnormal gear meshing, the entire ash scraping operation will be affected, and repairing these components is complex. Third, during the process of adding biomass fuel, the operator opens the first and second chamber doors and pours the biomass fuel into the chamber from a considerable height, which can easily damage the biomass fuel during the pouring process, causing it to loosen and affecting the combustion efficiency. Therefore, a biomass fuel stove needs to be designed to solve these problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a biomass fuel stove that solves the problem in the above-mentioned patent that there is a gap between the bottom of the baffle and the top of the partition, and thus some dust still exists on the surface of the partition, resulting in incomplete dust cleaning. At the same time, it solves the problem that biomass fuel is easily damaged during the feeding process, which affects the combustion efficiency.

[0007] The technical solution adopted by this application to solve its technical problem is: a biomass fuel stove. It mainly includes: A combustion assembly, comprising a combustion chamber connected to a frame; A feeding assembly is mounted on a combustion chamber, the feeding assembly including a feeding box slidably connected to the combustion chamber, suitable for storing biomass fuel during the combustion process; Waste scraping assembly, which is connected to the upper part of the combustion box, includes an assembly plate located inside the combustion box and adapted to move linearly, and a scraper connected below the assembly plate, adapted to scrape off the waste residue on the feed box; A cleaning assembly, which is attached to the lower part of the assembly plate, includes a cleaning brush roller adapted to clean the feed box.

[0008] Furthermore, the combustion assembly also includes a waste residue guide plate installed on the combustion chamber, a collection box connected to the combustion chamber, the waste residue guide plate being located above the collection box, and a cleaning door hinged to the combustion chamber.

[0009] Furthermore, the combustion chamber is connected to an exhaust pipe.

[0010] Furthermore, the feeding assembly also includes two sets of slide rails mounted on the combustion chamber, with a sliding plate mounted on the slide rails and the sliding plate being fixedly connected to the feeding box.

[0011] Furthermore, the waste scraping assembly also includes a bracket installed on the combustion chamber, a one-way screw rotatably connected to the bracket, a one-way slider sleeved on the one-way screw, intermediate plates connected to both sides of the one-way slider, and an irregularly shaped connecting rod connected to one end of the intermediate plate away from the one-way slider. The irregularly shaped connecting rod extends into the combustion chamber and connects to the assembly plate, and the scraper is located inside the feed box.

[0012] Furthermore, an adjustment disc is installed on the unidirectional lead screw.

[0013] Furthermore, the cleaning assembly also includes a rotating rod rotatably connected to the lower part of the assembly plate, a cleaning brush roller connected to the rotating rod, gears connected to both ends of the rotating rod, and a rack installed on the feeding box, with the gears meshing with the rack.

[0014] The beneficial effects of this application are as follows: The biomass fuel stove provided by this application, through the coordinated work of the waste scraping component and the cleaning component, the scraper can scrape off the waste residue at the bottom of the feeding box, reducing waste residue residue, while the cleaning brush roller cleans the feeding box during the pulling process of the feeding box, effectively reducing the attached waste residue and dust, thereby improving the cleaning effect of the device.

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] like Figures 1-5As shown, this application provides a biomass fuel stove, mainly including: a combustion assembly 1, which includes a combustion box 102 connected to a frame 101; a feeding assembly 2, which is installed on the combustion box 102 and includes a feeding box 201 slidably connected to the combustion box 102 for storing biomass fuel during combustion; a waste scraping assembly 3, which is connected to the upper part of the combustion box 102 and includes an assembly plate 307 located inside the combustion box 102 and adapted to linear movement; a scraper 308 is connected below the assembly plate 307 for scraping off waste from the feeding box 201; and a cleaning assembly 4, which is connected to the lower part of the assembly plate 307 and includes a cleaning brush roller 402 adapted to clean the feeding box 201. In the feeding assembly 2, the feeding box 201 is slidably connected to the combustion chamber 102, allowing workers to easily push the feeding box 201 containing biomass fuel into the combustion chamber 102 along the slide rail 202. The operation is simple and, compared to the traditional method of dumping fuel from a height, it avoids damage to the fuel during the falling process, ensuring combustion efficiency. The scraper 308 in the waste scraping assembly 3 cleans the feeding box 201 as it moves, effectively scraping off the waste residue on the feeding box 201. The cleaning brush roller 402 in the cleaning assembly 4 rotates synchronously as the feeding box 201 moves, further removing residual waste residue and dust from the feeding box 201, improving cleaning efficiency.

[0020] like Figure 2 and Figure 3 As shown, the frame 101 serves as the basic support structure and is securely connected to the combustion chamber 102 via welding. Combustion occurs inside the combustion chamber 102. The waste guide plate 104 is welded to a specific position inside the combustion chamber 102, corresponding to the top of the collection box 105. When combustion produces waste, the waste slides down the guide plate under gravity and falls precisely into the collection box 105, achieving orderly collection of waste. The exhaust pipe 103 is bolted to the combustion chamber 102. This connection method not only ensures a stable connection between the two but also effectively prevents smoke generated during combustion through a sealing design. Leakage is prevented, allowing smoke to be discharged directionally through the exhaust pipe 103, ensuring a safe and clean working environment. The cleaning door 106 is hinged to the combustion chamber 102 by stainless steel hinges. The stainless steel hinges have good corrosion resistance and durability, and are not easily damaged during long-term use, ensuring that the cleaning door 106 can be opened and closed flexibly. When it is necessary to clean and maintain the inside of the combustion chamber 102 or to treat the waste residue in the collection box 105, the cleaning door 106 can be opened conveniently to perform the corresponding operations. After the operation is completed, the cleaning door 106 can be closed, and the equipment can continue to be put into use. The feeding box 201 and the sliding plate 203 are fixed by welding. This connection method ensures that the two maintain a stable joint state during long-term push-pull operation and will not separate. The sliding plate 203 is slidably connected to two sets of stainless steel slide rails 202 installed on the combustion chamber 102. After polishing, the slide rails 202 have a smooth surface and a significantly reduced coefficient of friction, allowing the sliding plate 203 to slide smoothly back and forth on the slide rails 202. When it is necessary to add material to the combustion chamber 102, the operator only needs to push and pull the feeding box 201. With the sliding cooperation between the sliding plate 203 and the slide rails 202, the feeding box 201 can easily and accurately deliver the material to the designated position inside the combustion chamber 102 to complete the feeding operation. After feeding is completed, the feeding box 201 is pushed and pulled in the opposite direction to remove it from the combustion chamber 102, which facilitates subsequent material replenishment or cleaning and maintenance operations.

[0021] like Figure 4 As shown, the bracket 301 is bolted to the combustion chamber 102, providing stable support for the one-way lead screw 302. The one-way lead screw 302 is rotatably connected to the bracket 301 through a bearing, ensuring flexible rotation of the lead screw. The one-way slider 304 is threadedly connected to the one-way lead screw 302, enabling the slider to move up and down along the lead screw. The intermediate plate 305 is welded to both sides of the one-way slider 304. One end of the irregular connecting rod 306 is welded to the intermediate plate 305, and the other end is bolted to the assembly plate 307 for easy installation and disassembly. The scraper 308 is welded to the bottom of the assembly plate 307 to ensure the stability of the scraper 308 during the slag scraping process.

[0022] like Figure 5 As shown, when the feeding box 201 is pushed and pulled by the cooperation of the slide plate 203 and the slide rail 202, the rack 404 on the feeding box 201 moves accordingly. Based on the transmission principle of the gear 403 and rack 404, the gear 403 meshing with the rack 404 starts to rotate, which in turn drives the rotating rod 401 to rotate. At the same time as the rotating rod 401 rotates, the cleaning brush roller 402 rotates synchronously to clean the combustion box 102 and remove residual waste residue, dust and other impurities. This cleaning mechanism cleverly uses the movement of the feeding box 201 as a power source, without the need for an additional drive device, and realizes the automatic operation of the cleaning brush roller 402, effectively saving energy.

[0023] Working principle: The operator places biomass fuel into the feeding box 201. Since the feeding box 201 is slidably connected to the slide rail 202 installed on the combustion box 102 via the sliding plate 203, the feeding box 201 can be easily pushed into the combustion box 102 along the slide rail 202 to complete the feeding operation of biomass fuel. During this process, the waste scraping component 3 and the cleaning component 4 are located at the upper end of the feeding box 201, so they will not affect the normal feeding of biomass fuel. The combustion box 102 is installed on the frame 101. The biomass fuel is burned in the combustion box 102, and the generated smoke is discharged through the exhaust pipe 103 connected to the combustion box 102. When the biomass fuel has finished burning and it is necessary to clean the waste residue on the feed box 201, the adjusting disc 303 on the one-way screw 302 is rotated. The rotation of the one-way screw 302 drives the one-way slider 304 sleeved on it to move downward along the one-way screw 302. The intermediate plates 305 connected to both sides of the one-way slider 304 will drive the irregular connecting rod 306 to move downward with the one-way slider 304. At the same time, the irregular connecting rod 306 drives the assembly plate 307 to move downward in a straight line within the combustion chamber 102 until the one-way slider 304 reaches the one-way... At the lowest position of the lead screw 302, the scraper 308 moves to the bottom of the feed box 201 under the action of the assembly plate 307 and remains stationary. Then, the feed box 201 is pulled outward by the handle. As the feed box 201 is pulled outward, the scraper 308 can scrape off the waste residue at the bottom of the feed box 201. Under the action of gravity, the scraped waste residue slides down the waste residue guide plate 104 installed inside the combustion box 102 and finally falls into the collection box 105 located below, realizing the centralized collection of waste residue. Since gear 403 meshes with rack 404, the movement of feed box 201 will drive gear 403 to rotate through rack 404, which in turn drives rotating rod 401 to rotate synchronously. Cleaning brush roller 402 connected to rotating rod 401 also rotates accordingly, cleaning the bottom of feed box 201, greatly reducing the amount of waste residue and dust attached to the bottom of feed box 201. When feed box 201 is completely pulled out of combustion chamber 102, the cleaning work of the bottom of feed box 201 is basically completed. Next, the adjusting disc 303 on the one-way screw 302 is rotated in the opposite direction. The one-way screw 302 rotates in the opposite direction, driving the one-way slider 304 to move upward along the one-way screw 302. The one-way slider 304 drives the intermediate plate 305, and the intermediate plate 305 then drives the assembly plate 307 to move upward through the irregular connecting rod 306, so that the scraper 308 and the cleaning brush roller 402 return to the initial high position. At this time, the biomass raw material to be burned is placed inside the feeding box 201 and then pushed into the combustion box 102. In daily use, when the waste residue in the collection box 105 accumulates to a certain extent, open the cleaning door 106 hinged on the combustion box 102, take out the collection box 105 for cleaning, and after cleaning, put the collection box 105 back in its original position and close the cleaning door 106. This cycle is repeated so that the biomass fuel stove can operate continuously and stably, and realize convenient cleaning of biomass fuel waste residue.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
