Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically a biomass fuel burner. Background Technology

[0002] A biomass burner is a semi-gasification, automatically controlled biomass burner that uses organic biomass such as biomass pellets, wood chips, wood powder, and sawdust as fuel. It is generally divided into two types: air-cooled biomass burners and water-cooled biomass burners.

[0003] An existing patent (publication number: CN222688244U) discloses a biomass fuel industrial burner, including a furnace and a hopper located above the furnace. The hopper has a feeding port at its lower end and a perforation on its lower side wall. A cutter holder, inserted into the perforation, is positioned within the lower end of the hopper. A cutter is mounted on the cutter holder. A stop corresponding to the cutter is located on the inner wall of the lower end of the hopper. A driving device for moving the cutter holder is located outside the hopper. This invention has the following advantages and effects: When the operator observes arching at the lower end of the hopper through the observation window, the driving device is activated to move the cutter closer to the stop, cutting the biomass fuel, effectively solving the problem of biomass fuel arching. The first receiving cavity accommodates the cutter, and the second receiving cavity accommodates the stop, ensuring that normal feeding of the hopper is not disturbed.

[0004] The existing technology has the following problems: 1. When biomass fuel is piled up together for a long time, it will clump together due to some external factors. The existing burners cannot break up the clumps of biomass fuel, which makes it easy for the clumps of biomass fuel to accumulate at the feed inlet and cause blockage, thereby reducing the practicality of the burner; 2. When the existing burners burn biomass fuel, they cannot stir the biomass fuel during combustion, which makes the fuel piled up inside unable to burn effectively, resulting in incomplete combustion of biomass fuel and thus greatly reducing the combustion effect of biomass fuel. Utility Model Content

[0005] The purpose of this invention is to provide a biomass fuel burner to solve the problems mentioned in the background art, namely, that existing burners cannot break up agglomerated biomass fuel, causing agglomerated biomass fuel to easily accumulate at the feed inlet and cause blockage, and that existing burners cannot stir the biomass fuel during combustion, making the fuel accumulated inside unable to burn effectively, resulting in incomplete combustion of biomass fuel and thus significantly reducing the combustion effect of biomass fuel.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a biomass fuel burner, including a shell assembly 1, with connecting shafts 2 arranged on the inner two walls of the shell assembly 1 via bearings, a plurality of stirring seats 3 arranged on the outside of the connecting shafts 2, and four stirring rods 4 arranged on the outside of the plurality of stirring seats 3 respectively, a first gear 5 arranged at one end of the connecting shafts 2, a conveying box 6 arranged at the top of the shell assembly 1, a motor 7 arranged on one side of the conveying box 6, an auger shaft 8 arranged on the inner two walls of the conveying box 6 via bearings, a second gear 9 arranged at one end of the auger shaft 8, a main gear 10 arranged on the output shaft of the motor 7, a crushing box 11 arranged at the top of the conveying box 6, two crushing shafts 12 arranged on the inner two walls of the crushing box 11 via bearings, crushing rollers 13 arranged on the outside of the two crushing shafts 12, a third gear 14 arranged at one end of the two crushing shafts 12, and a secondary gear 15 arranged at one end of the crushing shafts 12.

[0023] In this embodiment, as Figure 1 As shown, the outer shell assembly 1 includes a combustion chamber body 101, a slag discharge port 102 is provided at the bottom center of the combustion chamber body 101, and support legs 103 are provided at the four corners of the bottom of the combustion chamber body 101.

[0024] In this embodiment, as Figure 1 As shown, the bottom of the combustion chamber body 101 is designed as an inclined structure. The inclined combustion chamber body 101 allows the fuel ash after combustion to be discharged smoothly from the ash discharge port 102 by its own gravity, thereby avoiding the accumulation of fuel ash inside the combustion chamber body 101.

[0025] In this embodiment, as Figure 3 As shown, four stirring rods 4 are equidistantly distributed on the outside of the stirring seat 3; they can stir the biomass fuel inside the combustion chamber body 101, so that the biomass fuel accumulated inside the combustion chamber body 101 can burn more completely, thereby greatly improving the combustion effect of biomass fuel.

[0026] In this embodiment, as Figure 2 As shown, the central axis of the motor 7 and the central axis of the auger shaft 8 are aligned; this enables the conveying of crushed biomass fuel, thereby preventing the accumulation and blockage of biomass fuel.

[0027] In this embodiment, as Figure 1 As shown, the first gear 5 and the second gear 9 are connected by a chain, and the main gear 10 and the auxiliary gear 15 are connected by a chain; this greatly improves the convenience of the burner during use, thereby increasing the practicality of the burner.

[0028] In this embodiment, as Figure 4 As shown, the two third gears 14 are meshed together; this enables the biomass fuel in the crushing box 11 to be broken up and crushed, solving the problem that the clumped biomass fuel is easy to accumulate at the feed inlet and cause blockage, thus meeting the requirements of biomass fuel burners.

[0029] The method of use and advantages of this utility model: When using this biomass fuel burner, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the combustion chamber body 101 is first placed in a designated position by the support legs 103. The motor 7 is started by the controller. Then, the biomass fuel is poured into the crushing chamber 11 through the feed inlet. The fuel enters the crushing chamber 11 and falls to the top of the two crushing rollers 13. At this time, the motor 7 drives the main gear 10 to rotate. The main gear 10 drives the secondary gear 15 to rotate through the chain. The secondary gear 15 drives the crushing shaft 12 to rotate. At the same time, the meshing transmission of the two third gears 14 causes the two crushing rollers 13 to rotate in opposite directions, thereby breaking up and crushing the biomass fuel in the crushing chamber 11. This solves the problem that the clumps of biomass fuel are easy to accumulate at the feed inlet and cause blockage.

[0031] The crushed biomass fuel falls into the conveying box 6. Then, the motor 7 drives the auger shaft 8 to rotate, transporting the fuel inside the conveying box 6 and preventing accumulation or blockage. The transported fuel then falls into the combustion chamber 101. The motor 7 then drives the second gear 9 via the auger shaft 8 to rotate. The second gear 9 drives the first gear 5 via a chain, which in turn drives the connecting shaft 2. Simultaneously, the connecting shaft 2 drives the stirring rod 4 via the stirring seat 3 to rotate, thus stirring the biomass fuel inside the combustion chamber 101. This ensures more complete combustion of the biomass fuel, significantly improving its combustion efficiency. The fuel ash from the combustion is discharged smoothly from the ash discharge port 102 by gravity, preventing ash accumulation inside the combustion chamber 101.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
