Description

Technical Field

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

[0002] Biomass pellets are a type of clean fuel made from agricultural and forestry waste (such as straw, sawdust, rice husks, etc.) through processes such as crushing, drying, and extrusion.

[0003] Biomass pellets need to be cooled to transition them from a thermoplastic state to a stable state, thereby ensuring their physical strength, storage safety, and combustion performance.

[0004] However, when existing biomass pellet cooling devices are used for cooling, the biomass pellets entering the cooling device are mostly in a stacked state. The inner layer of the stacked biomass pellets is difficult to cool, which can easily lead to moisture absorption and reduced combustion efficiency in the future. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a biomass pellet cooling device that can disperse and cool biomass pellets.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A biomass pellet cooling device includes a shell, a breathable baffle, a dispersion section, a feed hopper, a discharge pipe, an air inlet pipe, an air outlet pipe, and an exhaust fan;

[0008] The outer shell is divided into an air inlet chamber, a material discharge chamber, and an air outlet chamber by two vertically placed ventilated partitions. An air inlet pipe is connected to the air inlet chamber. An air outlet pipe is connected to the air outlet chamber. An exhaust fan is installed on the air outlet pipe. The dispersing part is fixed to the upper end of the outer shell, and its lower part is located in the material discharge chamber. The feeding hopper is connected to the outer shell and extends into the outer shell, with its lower end located above the lower part of the dispersing part. Several ventilation holes are opened on the ventilated partitions.

[0009] Furthermore, the dispersing unit includes a motor detachably connected to the upper end of the housing, a rotating shaft fixed to the motor and extending into the housing, and a dispersing disc detachably connected to the lower end of the rotating shaft.

[0010] Furthermore, the dispersing disc includes a cylinder and an arc-shaped segment integrally formed with the lower end of the cylinder; the upper end of the arc-shaped segment matches the shape of the lower end of the cylinder, and the lower end is rectangular with a strip-shaped hole.

[0011] Furthermore, a circular block is integrally formed at the lower center of the arc-shaped segment, located at the strip-shaped hole, which facilitates detachable connection to the rotating shaft.

[0012] Furthermore, the feed hopper includes a conical section and a connecting pipe section fixedly connected to the conical section; the connecting pipe section extends into the discharge chamber and is located above the dispersing disc.

[0013] Furthermore, a valve is provided on the discharge pipe; a bracket is fixedly connected to the lower part of the outer casing.

[0014] The beneficial effects of this utility model are:

[0015] (1) By setting up a dispersion section, the motor on the dispersion section drives the rotating shaft to rotate and drive the dispersion disk to rotate, so that the biomass particles falling into the dispersion disk can be evenly dispersed as they rotate, leaving space for the cold airflow to pass through;

[0016] (2) The installation of air inlet pipe, air outlet pipe and exhaust fan can enable the cold airflow to flow laterally to cool the biomass pellets;

[0017] (3) This application enables the stacked biomass pellets to disperse out of the space where cold air flows, and cools the biomass pellets through the lateral airflow, thus ensuring the quality of the biomass pellets. Attached Figure Description

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figure 1-4 As shown, a biomass pellet cooling device includes an outer shell 1, a breathable partition 2, a dispersion section 3, a feed hopper 4, a discharge pipe 5, an air inlet pipe 6, an air outlet pipe 7, and an exhaust fan 8. The outer shell 1 is divided into an air inlet chamber 11, a material discharge chamber 12, and an air outlet chamber 13 by two vertically placed breathable partitions 2. The air inlet chamber 11 is connected to the air inlet pipe 6. The air outlet chamber 13 is connected to the air outlet pipe 7. An exhaust fan 8 is installed on the air outlet pipe 7. The dispersion section 3 is fixed to the upper end of the outer shell 1, and its lower part is located in the material discharge chamber 12. The feed hopper 4 is connected to the outer shell 1 and extends into the outer shell 1, and its lower end is located above the lower part of the dispersion section 3. A plurality of ventilation holes 21 are opened on the breathable partition 2.

[0032] It should be noted that the outer shell 1 provides space for air intake, air exhaust, and biomass pellet drop; the permeable baffle 2 serves as both airflow and isolation; the vent hole 21 of this application has a diameter smaller than the size of the produced biomass pellets to prevent biomass pellets from entering the air intake chamber 11 and the air outlet chamber 13; the dispersion section 3 can rotate to evenly disperse the biomass pellets into the dropping chamber 12; the feed hopper 4 is used for the entry of biomass pellets; the discharge pipe 5 can collect the cooled biomass pellets; the arrangement of the air intake pipe 6, the air outlet pipe 7, and the exhaust fan 8 allows the cold airflow to flow laterally to cool the biomass pellets; the air intake pipe 6 can be extended to the outside to draw in cold airflow, the air outlet pipe 7 is used for the airflow to exit, and the exhaust fan 8 can increase the airflow velocity; the vent hole 21 can better disperse the airflow.

[0033] Specifically, the dispersing section 3 includes a motor 31 detachably connected to the upper end of the outer casing 1, a rotating shaft 32 fixed to the motor 31 and extending into the interior of the outer casing 1, and a dispersing disc 33 detachably connected to the lower end of the rotating shaft 32. The motor 31 can drive the rotating shaft 32 to rotate, thereby causing the dispersing disc 33 to rotate, so that the material falling from the feed hopper 4 is evenly dispersed and facilitates cooling.

[0034] The dispersing disc 33 includes a cylinder 331 and an arc-shaped segment 332 integrally formed with the lower end of the cylinder 331; the upper end of the arc-shaped segment 332 matches the shape of the lower end of the cylinder 331, and the lower end is rectangular with a strip-shaped hole 333. The cylinder 331 serves as a containment; the arc-shaped segment 332 facilitates the collection of materials and their flow out through the strip-shaped hole 333.

[0035] To facilitate the connection of the rotating shaft 32, a circular block 334 is integrally formed at the lower middle part of the arc-shaped segment 332, located at the strip hole 333, which is convenient for detachable connection of the rotating shaft 32.

[0036] In order to facilitate the production of biomass pellets that need to be cooled and enter the cooling device, the feed hopper 4 includes a conical section 41 and a connecting pipe section 42 fixedly connected to the conical section 41; the connecting pipe section 42 extends into the discharge chamber 12 and is located above the dispersing disc 33.

[0037] In order to control the output of biomass pellets and reserve discharge space below the biomass pellet cooling device, a valve 51 is provided on the discharge pipe 5; a bracket 9 is fixedly connected to the bottom of the outer shell 1.

[0038] The working principle of this utility model:

[0039] During operation, freshly prepared biomass pellets enter the dispersion disc 33 located inside the outer shell 1 through the feed hopper 4. The motor 31 drives the rotating shaft 32 to rotate, causing the dispersion disc 33 to rotate, so that the biomass pellets falling into the dispersion disc 33 can be evenly dispersed as they rotate. The arrangement of the air inlet pipe 6, the air outlet pipe 7, and the exhaust fan 8 allows the cold airflow to flow laterally to cool the biomass pellets. The air inlet pipe 6 can extend to the outside to draw in cold airflow, the air outlet pipe 7 is used for the airflow to flow out, and the exhaust fan 8 can increase the airflow speed. The ventilation hole 21 can better disperse the airflow, and the cooled biomass pellets are collected through the discharge pipe 5.
