Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solid waste management and waste resource recycling, and specifically relates to a garden waste disposal device. Background Technology
[0002] Currently, while the total amount of urban green space is steadily increasing, the waste generated by landscaping is also increasing. Traditional methods of disposing of green waste through incineration or landfill not only waste biomass resources and occupy land resources, but also increase waste disposal costs. Furthermore, landscaping waste, unlike household or industrial waste, is a valuable resource with significant utilization potential. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a garden waste disposal device that can process garden waste into bio-particles for reuse.
[0004] The purpose of this utility model is achieved through the following technical solution: a garden waste disposal device, characterized in that: it includes a crushing unit, a dryer and a pelletizer, the crushing unit includes a primary crusher and a fine crusher connected in sequence, the discharge end of the fine crusher is connected to the feed end of the dryer, a hot air furnace for providing hot air to the dryer is installed above the feed inlet of the dryer, and the discharge end of the dryer is connected to the feed end of the pelletizer unit.
[0005] A garden waste disposal device further includes dust collectors, with dust collectors installed at the discharge end of the dryer and above the pellet mill, respectively.
[0006] The dust collector includes a cyclone dust collector and a bag filter dust collector. A primary cyclone dust collector is installed at the discharge end of the dryer, and a secondary cyclone dust collector is connected above the feed inlet of the granulator. The output end of the secondary cyclone dust collector is connected to the bag filter dust collector.
[0007] A garden waste disposal device also includes a packaging machine, wherein the discharge end of the pelletizing unit is connected to the packaging machine.
[0008] The beneficial effects of this utility model are:
[0009] 1. This device crushes, pulverizes, dries, and extrudes garden waste into biomass pellet fuel.
[0010] 2. The production line is equipped with cyclone dust collectors and bag filters, which perform two dust removal processes. A primary cyclone dust collector is installed at the discharge end of the dryer to remove water vapor and dust from the exhaust gas of the drum dryer. A secondary cyclone dust collector and bag filter are installed above the feed inlet of the granulator to adsorb and reduce the dust generated in the granulation process. The two sets of dust removal equipment are installed at different dusty process locations to effectively reduce the spread of dust and achieve dust removal on the production line.
[0011] 3. Select appropriate equipment, arrange it reasonably, follow scientific processes, and be environmentally friendly. Attached Figure Description

Detailed Implementation
[0015] Example: As shown in the figure, a garden waste disposal device includes a crushing unit 1, a dryer 2, a dust collector 3, a pelletizer 4, and a packaging machine 5. The crushing unit 1 includes a primary crusher 1-1 and a fine crusher 1-2 connected in sequence. The primary crusher 1-1 is a plate-type integrated crusher. The collected garden waste is placed into the plate-type integrated crusher 1-1 for coarse crushing, which breaks it into primary crushed material with a particle size of less than 3 cm. The particle size of the primary crushed material does not meet the pelletizing requirements and needs to be finely crushed. The material is then conveyed by belt conveyor 7. -1 is fed into the fine crusher 1-2, where it is finely ground into material smaller than 5 mm. Because the initial material has a high moisture content, it needs to be dried to quickly meet granulation requirements. The finely ground material falls from the outlet of the fine crusher 1-2 onto the No. 2 belt conveyor 7-2 below it, which then feeds it into the rotary drum dryer 2. Hot air is introduced into the rotary drum dryer 2 by the hot air furnace 6 installed above the inlet to dry the finely crushed material. After drying, the moisture content of the material is less than 1%. 5%, as the drum dryer 2 rotates, the dried material is conveyed to the discharge end of the drum dryer 2, falling onto the No. 3 belt conveyor 7-3 below the discharge end of the drum dryer 2. The No. 3 belt conveyor 7-3 then feeds the material into the pelletizing unit 4 for extrusion and pelletizing, producing biomass pellets with a diameter of 8 mm. A primary cyclone dust collector 3-1 is installed at the discharge end of the drum dryer 2, and a secondary cyclone dust collector 3-2 is connected above the feed end of the pelletizing unit 4. The discharge end of the secondary cyclone dust collector is connected to a bag filter 3-3. The primary cyclone dust collector 3-1... The rotary drum dryer's discharge end undergoes primary dust removal to remove water vapor and dust from the exhaust gas. Secondary cyclone dust collector 3-2 and baghouse dust collector 3-3 are used to adsorb and reduce dust generated during the pelleting process. These two sets of dust collectors are installed at different dusty process locations, effectively reducing dust diffusion and achieving dust control throughout the production line. A No. 4 belt conveyor 7-4 is installed below the discharge end of the pellet mill unit 4, which feeds the biomass pellets into a ton bag packaging machine 5. After being discharged and packaged by the ton bag packaging machine 5, the packaged biomass pellets become finished fuel. Using this device to process garden waste into biomass fuel meets environmental protection requirements, realizes energy reuse, and has development potential and a broad market prospect.
