Description

Technical Field

[0001] The utility model relates to the technical field of biofuels, in particular to a briquetting device for biomass particles. Background Art

[0002] Biomass pellets are a renewable energy product typically made from organic materials such as wood chips, crop residues (e.g., rice husks, corn stalks), herbs, and other agricultural and forestry waste. After pre-processing steps like drying, crushing, and mixing, these raw materials are extruded through a die under high pressure to form cylindrical pellets with diameters generally between 6 and 10 mm. This form makes them easy to transport and store, and improves combustion efficiency.

[0003] The Chinese invention patent with publication number CN105034432B disclosed a biomass fuel briquette forming machine on March 23, 2018, including a forming device and a power device. The forming device includes a cross shaft, a wolf tooth wheel, and a lower die plate. The power device includes a main shaft, a reducer, and an electric motor. The bottom end of the main shaft is connected to the reducer for transmission, and the upper end passes through the lower die plate and the center of the cross shaft and is rotatably connected to the cross shaft. The wolf tooth wheel is symmetrically mounted on the shaft end of the cross shaft. The upper surface of the lower die plate is provided with a circular mold cavity groove, and the mold cavity groove is provided with multiple circles of circumferentially evenly arranged rolling groove holes. The wolf tooth wheel teeth roll and roll through the rolling groove holes. A plurality of molding discharge holes are evenly distributed in the rolling groove holes, and the molding discharge holes are composed of an upper small-aperture molding hole area and a lower large-aperture discharge hole area. The present invention has low requirements for raw materials. The raw material length of 10-30 cm and the water content of 13-35% meet the production process requirements. The raw materials do not need to go through the previous fine powder crushing, screening and drying processes; and it is adapted to the best driving force - a three-stage planetary reducer. The equipment has an input power of 75 kilowatts, an output speed of 40 r / min, a rated torque of 117000 NM, and an output of 2-3 tons / hour. It has low power and high output, which greatly reduces production costs.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the biomass particles in the prior art are all formed into a cylindrical shape, which is convenient for processing and transportation, but cannot be conveniently used in a quantitative manner during use, and other tools need to be used for measurement. At the same time, they occupy a larger area when stacked. Utility Model Content

At the same time, a larger area is occupied when stacking. A briquetting device for biomass pellets is provided.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] Furthermore, a plurality of raw material boxes are plugged into the support frame.

[0011] Furthermore, a collection box is inserted between the raw material boxes.

[0012] The utility model provides a biomass pellet briquetting device with the following beneficial effects:

[0013] 1. The utility model pours the biomass raw materials into one of the two left and right feeding troughs in three columns, and then pushes the electric push rod once, so that the biomass raw materials are located under the compression unit, and at the same time, the other of the two left and right feeding troughs is filled with biomass raw materials, and then the compression unit works to compress, and then the electric push rod is pushed once again, and the compressed briquettes are suspended in the air for easy removal, and at the same time, the feeding trough filled with biomass raw materials is moved to the bottom of the compression unit, and compressed again to form briquettes. The briquettes after forming are in the shape of a cube, and one side has multiple gaps, which is convenient for bagging and boxing, so that they can be stacked and stored. At the same time, when in use, the number of briquettes can be counted to determine the weight, and the briquettes can also be broken into pieces of briquettes, which can be used flexibly, solving the problem that the existing briquettes cannot be conveniently measured by weight for use;

[0014] 2.
