A biomass pellet combustion device

Abstract

This utility model discloses a biomass pellet combustion device, including a base, a storage bin, a combustion chamber, a first motor, an auger, a rolling drum, a first gear, a second gear, a second motor, and a driven wheel. The advantages of this utility model are: by incorporating the rolling drum, which serves as the combustion chamber for the biomass pellets, the second motor drives the second gear to rotate, which in turn drives the first gear, causing the rolling drum to rotate. Simultaneously with combustion, the ash from the combustion process is discharged through a discharge hole into an ash collection trough located below the combustion chamber, effectively ensuring complete combustion of the biomass pellets without interfering with the combustion of newly entering biomass pellets, resulting in higher combustion efficiency.

Description

Technical Field

[0001] This utility model relates to the field of biomass pellet combustion technology, and in particular to a biomass pellet combustion device. Background Technology

[0002] A biomass pellet combustion device is a highly efficient and environmentally friendly device that specifically burns biomass pellet fuel made from compressed agricultural and forestry waste to generate heat or electricity. However, in existing biomass pellet combustion devices, the ash left after combustion always remains in the combustion chamber, which is not conducive to the combustion of newly entered biomass pellets, resulting in incomplete combustion. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a biomass pellet combustion device.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

The combustion chamber is fixedly connected to the upper end of the base. The base is fixedly connected to the side of the storage bin. The first motor is fixedly connected to the base and located between the storage bin and the combustion chamber. One end of the auger is fixedly connected to the combustion chamber and extends into the combustion chamber. The first motor drives the auger via a belt. The rolling drum is located in the combustion chamber, with one end sleeved within the combustion chamber and extending into it. Part of the outer side extends out of the combustion chamber, and the other end extends out of the combustion chamber body; the end of the roller drum near the auger has a gap with the combustion chamber body and a first gear is fixedly connected thereto; a second motor is fixedly connected to the outer side of the combustion chamber body near the combustion chamber body; the output end of the second motor extends into the combustion chamber body and is fixedly connected to the second gear; the second gear meshes with the first gear for transmission; two symmetrically arranged driven wheels for supporting the roller drum are rotatably connected to the lower side of the combustion chamber body away from the first gear; a number of material leakage holes are opened in the part of the combustion chamber body located in the combustion chamber body.

[0006] Furthermore, a hopper for receiving materials is provided above the auger.

[0007] Furthermore, the storage bin is provided with a discharge pipe on the side near the hopper; the outlet of the discharge pipe is located above the hopper.

[0008] Furthermore, a valve is installed on the discharge pipe.

[0009] Furthermore, the second motor is fixed by a support frame installed on the combustion chamber.

[0010] Furthermore, a fan is connected to the combustion chamber below the two driven wheels via a pipe.

[0011] Furthermore, the end of the roller cylinder near the auger is provided with an annular protrusion; there is a gap between the annular protrusion and the auger.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a rolling drum, which is the place where biomass pellet fuel is placed for combustion, the second motor can drive the second gear to rotate, which in turn drives the first gear to rotate, thereby causing the rolling drum to rotate. While burning, the ash after combustion can also be discharged from the leakage hole through the rotation into the ash collection trough set below the combustion chamber. This effectively ensures that the biomass pellets burn completely and does not interfere with the combustion of newly entered biomass pellets, resulting in higher combustion efficiency.

The combustion chamber 3 is fixedly connected to the upper end of the base 1. The base 1 is fixedly connected to the side of the storage bin 2. The first motor 4 is fixedly connected to the base 1 and located between the storage bin 2 and the combustion chamber 3. One end of the auger 5 is fixedly connected to the combustion chamber 3 and extends into the combustion chamber 3. The first motor 4 drives the auger 5 through a belt 7. The roller drum 6 is located in the combustion chamber 3, with one end sleeved and extending into the combustion chamber 3. The outer side of part of the cavity 3 extends out of the combustion cavity 3 at the other end; the end of the roller 6 near the auger 5 has a gap with the combustion cavity 3 and a first gear 8 is fixedly connected thereto; a second motor 10 is fixedly connected to the outer side of the combustion cavity 3 near the combustion cavity 3; the output end of the second motor 10 extends into the combustion cavity 3 and is fixedly connected to a second gear 9; the second gear 9 meshes with the first gear 8 for transmission; two symmetrically arranged driven wheels 11 for supporting the roller 6 are rotatably connected to the lower side of the combustion cavity 3 away from the first gear 8; a number of material leakage holes 61 are opened in the part of the combustion cavity 3 located in the combustion cavity 3.

[0026] It should be noted that the base 1 facilitates the installation of other components; the storage bin 2 is used to hold biomass pellet fuel; the combustion chamber 3 is the main space for biomass fuel combustion; the first motor 4 can drive the auger 5 to rotate via the belt 7 to feed the biomass pellet fuel into the combustion chamber 3; the roller drum 6 is the place where the biomass pellet fuel is burned; the second motor 10 can drive the second gear 9 to rotate, thereby driving the first gear 8 to rotate, which in turn causes the roller drum 6 to rotate. While burning, the ash after combustion can also be discharged from the leakage hole 61 through the rotation into the ash collection trough located below the combustion chamber 3, which effectively ensures the full combustion of biomass pellets and does not interfere with the combustion of newly entered biomass pellets in the roller drum 6, resulting in higher combustion efficiency; the ash collection trough 12 is designed to be removable for easy ash removal.

[0027] To facilitate material feeding, a hopper 51 for receiving materials is provided above the auger 5.

[0028] To facilitate the outflow of materials from the storage bin 2 and control the flow rate of materials, a discharge pipe 21 is provided on the side of the storage bin 2 near the hopper 51; the outlet of the discharge pipe 21 is located above the hopper 51, and a valve 22 is provided on the discharge pipe 21.

[0032] To prevent biomass pellets from flowing out from the junction of the auger 5 and the roller drum 6, the end of the roller drum 6 near the auger 5 is provided with an annular protrusion 62; there is a gap between the annular protrusion 62 and the auger 5, and the gap is provided by the annular protrusion 62 to ensure that the biomass pellets are effectively prevented from flowing out.

[0033] The working principle of this utility model:

[0034] During operation, biomass pellets flow from the discharge pipe 21 located on the side of the storage bin 2 near the hopper 51 into the hopper 51, and are transported to the roller drum 6 by the auger 5. The roller drum 6 is the place where biomass pellet fuel is burned. The second motor 10 can drive the second gear 9 to rotate, which in turn drives the first gear 8 to rotate, thereby causing the roller drum 6 to rotate. While burning, the ash after combustion can also be discharged from the leakage hole 61 through the rotation into the ash collection trough located below the combustion chamber 3, which effectively ensures that the biomass pellets burn completely and does not interfere with the combustion of newly entered biomass pellets in the roller drum 6, resulting in higher combustion efficiency.
