Description

Technical Field

[0001] This utility model relates to the field of biomass processing equipment technology, specifically a biomass fuel thermal energy conversion device. Background Technology

[0002] Biomass fuel refers to the combustion of biomass materials as fuel, mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice husks, etc.). It is mainly different from fossil fuels. Straw is a type of biomass fuel. After the straw is gasified, it undergoes pyrolysis and reduction reactions to produce combustible gas, which is the thermal energy conversion of biomass fuel. This requires the use of a biomass fuel thermal energy conversion device.

[0003] Patent publication number "CN221117360U", entitled "A Thermal Energy Conversion Device for Biomass Fuel", includes a housing. A door is installed on the outer wall of the front of the housing near the bottom. A crushing mechanism is located at the center of the outer wall of the top of the housing, and the bottom end of the crushing mechanism is connected to the interior of the housing. An air supply mechanism is installed on one outer wall of the housing near the bottom. A cleaning box is fixedly installed on the outer wall of the housing away from the air supply mechanism. The above-mentioned utility model removes dust by adsorbing it with an activated carbon adsorption net, purifies it by spraying it with an atomizing nozzle, and after completion, the liquid is separated by a second air supply machine and the clean gas is discharged through an exhaust pipe. The gas is cleaned through the above series of processes.

[0004] When the aforementioned patent chops straw, the continuous input of different amounts of biomass fuel (such as straw) can easily lead to uneven and unstable feeding. Uneven and unstable feeding can result in uneven distribution of straw in the chopping component, which in turn leads to poor straw chopping effect. Poor chopping effect will directly affect the sufficiency and efficiency of the subsequent combustion process. Therefore, a biomass fuel thermal energy conversion device is proposed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a biomass fuel thermal energy conversion device, including a box 1, a chopping component 2 fixedly connected to the top of the box 1, a clamping feeding component 3 installed at the feeding end of the chopping component 2, and a cleaning component 5 installed at the discharge end of the box 1.

[0024] The shredding assembly 2 includes a tank 201, which is fixedly installed on the top of the box 1, and a cutting device is installed inside the tank 201.

[0025] The clamping and feeding assembly 3 includes a feeding component 301, which is fixedly installed at the feeding end of the tank 201. A rolling cylinder 302 is rotatably connected inside the feeding component 301. A motor 303 for controlling the rotation of the rolling cylinder 302 is fixedly connected outside the feeding component 301. A moving frame 304 is slidably connected inside the feeding component 301. A moving cylinder 305 is rotatably connected inside the moving frame 304. A moving component 306 is slidably connected inside the feeding component 301. A spring damping device 307 is fixedly connected between the moving component 306 and the moving frame 304. An adjustment assembly 4 for adjusting the position of the moving component 306 is installed between the moving component 306 and the feeding component 301.

[0026] The adjustment assembly 4 includes a first threaded rod 401, the outer wall of the first threaded rod 401 is threadedly connected to the inner wall of the feed member 301, and one end of the first threaded rod 401 is rotatably connected to one side of the moving member 306.

[0027] The cutting device includes a second motor 202, which is fixedly installed at the top of the tank 201. The output end of the second motor 202 passes through the top of the tank 201 and is fixedly connected to a transmission rod. A rotating blade 203 is fixedly connected to the top of the transmission rod, and a cutting blade 204 is fixedly connected to the outer wall of the transmission rod.

[0028] The cleaning component 5 includes a frame 501, which is fixedly installed at the discharge end of the box 1. A first filter plate 502 is fixedly connected inside the frame 501. A second filter plate 503 is fixedly connected to both sides of the first filter plate 502. Collection boxes 504 are installed on both sides of the box 1. A spray water device is fixedly connected to the top inside the frame 501.

[0029] The feed component 301 has a sliding groove inside, and the bottom end of the moving frame 304 is slidably connected to the inside of the feed component 301 through the sliding groove.

[0030] The inner wall of the feed component 301 is provided with a threaded hole, and the outer wall of the first threaded rod 401 is threadedly connected to the inner wall of the feed component 301 through the threaded hole.

[0031] The straw is moved into the tank 201 through the feeder 301. The initial elastic force of the first spring damper 307 is controlled based on the amount of straw in the tank, ensuring stable straw entry. The first threaded rod 401 rotates and moves, controlling the position of the moving part 306 within the feeder 301. The moving part 306 moves within the chute, while the moving frame 304 also moves along the chute on the feeder 301. The movement of the moving part 306 adjusts the initial elastic force of the first spring damper 307, effectively clamping straw of varying input amounts. The output of the first motor 303 rotates, and the rolling drum 302 rotates synchronously. The rolling drum 302 and the moving drum 305 clamp the straw, ensuring stable input into the tank 201. The chute does not... Only a sliding connection is achieved between the moving frame 304 and the feeding component 301, while limiting the moving distance of the moving frame 304. Under the action of the first spring damper 307, the moving frame 304 will not move when the moving component 306 moves, but the elastic force at both ends of the first spring damper 307 will change. By changing the elastic force of the first spring damper 307, the straw can be clamped. Through the cooperation of the first spring damper 307 and the adjustment component 4, the initial elastic force of the first spring damper 307 can be dynamically adjusted according to the straw inventory, thereby achieving effective clamping and stable input of straw with different input amounts, solving the problem of unstable feeding. Based on the continuous and stable input of biomass, the chopping component 2 can be guaranteed to chop the biomass, thereby ensuring the efficiency of the subsequent heat energy conversion operation inside the box 1.

[0032] After the straw enters the tank 201, the output end of the second motor 202 rotates, and through the transmission rod, the rotating blade 203 and the cutting blade 204 rotate synchronously. During the rotation, the rotating blade 203 cuts the straw at the feed port of the tank 201, and the cutting blade 204 can further reduce the size of the cut straw to ensure complete combustion. The chopped straw enters the box 1, where it undergoes thermal energy conversion, and gas is generated in the process.

[0033] Gas is discharged into frame 501. The gas outlet of frame 501 is at the bottom, while the gas is at the top of frame 501 when it is discharged. Therefore, as the gas is continuously discharged and sprayed by the spray water device, the gas is cooled and passes through filter plate 502 and filter plate 503. The gas particles are blocked by filter plate 502 and filter plate 503. The spray water device switches to water spray mode. In water spray mode, the particles on filter plate 502 and filter plate 503 reach the collection box 504 under the action of water flow, realizing the collection of particles. The cleaning component 5 sprays and cools the gas discharged into frame 501 through the spray water device. Then, when the gas passes through filter plate 502 and filter plate 503, the particles are effectively blocked. The spray device then switches to water spray mode, using water flow to collect particulate matter into collection box 504, achieving thorough collection of particulate matter and significantly improving the gas cleaning effect.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended embodiments and their equivalents.
