Problems solved by technology
[0002] The bio-organic fertilizer prepared by fermentation by adding biological beneficial bacteria to the sludge after urban sewage treatment, human and animal manure, food processing residues and organic crushed materials generally has a high water content, reaching 40-50%. Water content, fertilizer granulation is difficult. The traditional dehydration method is converter drying. This drying method is difficult to control the temperature. When the temperature is higher than 75°C during the granulation process, the beneficial microorganisms in the fertilizer will be killed.
Drying consumes a lot of energy, labor and time

The invention discloses a vacuum dehydration device for a granulating machine of biotic organic fertilizer. The device is formed by sequential connection of a vacuum chamber, a vacuum tank, a dehydration tank and a vacuum pump through air ducts. One end of the vacuum chamber is connected with a double-shaft stirring extrusion machine, and the other end of the vacuum chamber is connected with a spiral extrusion machine. The device has the beneficial effects that water in fertilizer can be pumped out by the adoption of a vacuum negative pressure before granulating biotic organic fertilizer, so that the fertilizer is enabled to be suitable for granulating.
Description
technical field [0001] The invention relates to a biological organic fertilizer, in particular to a vacuum dehydration device of a biological organic fertilizer granulator. Background technique [0002] The bio-organic fertilizer prepared by fermentation by adding biological beneficial bacteria to the sludge after urban sewage treatment, human and animal manure, food processing residues and organic crushed materials generally has a high water content, reaching 40-50%. Water content, fertilizer granulation is difficult. The traditional dehydration method is converter drying. This drying method is difficult to control the temperature. When the temperature is higher than 75°C during the granulation process, the beneficial microorganisms in the fertilizer will be killed. Drying consumes a lot of energy, labor and time. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a kind of vacuum dehydrat...
