Device capable of continuously drying rod-shaped biomass bales in different shapes and sizes

Abstract

The invention relates to a device capable of continuously drying rod-shaped biomass bales in different shapes and sizes. The device can continuously dry the biomass bales in different shapes and sizes by using waste flue gas or hot air and remove dust from the waste flue gas, and can put the bales in different specifications and sizes onto a slideway (3) of a drying channel (7). The device is provided with a channel (16) with an upward opening, the channel (16) presses the waste flue gas (30) or hot air (41) with pressure into the biomass bales, an air cushion (27) can be formed between the waste flue gas (30) or hot air (41) and the biomass bales and reduces the effective weight of the biomass bales, and the slideway (3) uses a polytetrafluoroethylene plate to reduce the thrust required for pushing the bales. The angle of a bale push shield (2) can be adjusted to facilitate the feeding operation of a forklift. The hot flue gas (37) and fresh air (38) are quickly mixed through a gas mixing tower (36) so as to prevent the re-synthesis of dioxin. The device can also be used for drying round forage bales and the like.

Description

technical field [0001] The invention relates to the design and structure of a device capable of continuously drying rod-shaped biomass bales of different shapes and sizes. It can also be used for dedusting the waste flue gas of drying straw bales, and can also dry protein green plant feed such as animal feed at low cost. Background technique [0002] According to the patent CH202010683508.01, in the fully automatic drying device for drying straw bales using exhaust gas from the tail of the combustion system, only round bales are preferred during drying operations and are carried by chain-driven conveyors through the drying channel. Seen from the side, the tail flue gas from the combustion system blows through the bale horizontally, so a special device must be used to horizontally press the straw round bale on the fixed air supply hole, which requires a large exhaust gas pressure and the process is more complicated, and Operator intervention is also required for large deviat...

AI Technical Summary

Problems solved by technology

Seen from the side, the tail flue gas from the combustion system blows through the bale horizontally, so a special device must be used to press the straw round bales horizontally on the fixed air supply hole, which requires a large exhaust gas pressure and the process is more complicated, and Operator intervention is also required for large deviations in straw bale dimensions

[0003] The chain-driven conveying system contains support tubes, support rollers and bearings that are susceptible to corrosion. Round bales or square bales of different sizes cannot be dried at the same time. The bales pass through without being filtered by the straw round bales, which affects the smoke and dust emission value

[0004] Drying protein-rich green plants to produce animal feed consumes a lot of energy. At present, there is no device or equipment that uses the device used to dry straw bales to dry green plants.
