Embodiment Construction

[0037] Attached below figure 1 The present invention is further described.

[0038] Such as figure 1 As shown, the device for preparing fertilizers provided by the present invention using Hyacinth hyacinthus comprises a feed inlet 1, a front fermentation tank body 2, a stirring rod 3, a stirring blade 4, a temperature sensor 5, an air collecting port 6, a frequency conversion fan 7, a first A valve 8, a second valve 9, a solar collector 10, a discharge port 11, a first-stage conveyor belt 12, an electric screening machine 13, a second-stage conveyor belt 14, a post-fermentation tank body 15, a solar panel 16 and an inverter and energy storage system 17 .

[0039] Among them, after the material passes through the main fermentation stage in the pre-fermentation tank body 2, it is sent into the electric screening machine 13 through the first conveyor belt 12 through the discharge port 11, and the completely reacted material in the main fermentation stage enters the post-ferment...

Abstract

The invention relates to a device and a method for preparing fertilizer by using eichhornia crassipes. The device comprises a solar power supply system, an air-blast system, a pre-fermentation tank body, an electric sieving machine and a post-fermentation tank body, wherein a feeding port and a gas collecting port are formed at the top of the pre-fermentation tank body; a discharging port is formed at the bottom of the pre-fermentation tank body; a stirring device is arranged in the pre-fermentation tank body; a first-stage conveying belt is arranged between the discharging port of the pre-fermentation tank body and the inlet of the electric sieving machine; a second-stage conveying belt is arranged between the outlet of the electric sieving machine and the inlet of the post-fermentation tank body; and the air-blast system is used for providing air with adjustable wind quantity for the pre-fermentation tank body. According to the method, aerobic composting of the eichhornia crassipes is completed through aerobic main fermentation and after-ripening stages, the adding ratio of the eichhornia crassipes to composite culture to nitrogen-retaining agent to wood dust is 1:(0.005-0.015):0.8:(0.04-0.1), and the problems of long one-time composting cycle and low efficiency are effectively solved. By the device and the method, the fertilizer, which is completely degraded, has rich nutrition and can effectively improve soil, can be obtained under the conditions of short time, low cost and easy operation.

Description

technical field [0001] The invention belongs to the technical field of ecological control of water pollution and resource utilization of floating water plants, and in particular relates to a device and method for preparing fertilizer by using water hyacinth lotus. Background technique [0002] Water hyacinth is a kind of floating herbaceous plant, native to Brazil, scattered in water bodies as an ornamental population, after it was introduced into my country as a flower, it was widely planted as an ornamental and water purification plant, but due to its extremely high reproductive ability Strong, it grows wildly in lakes and rivers, and has many negative effects, such as blocking rivers, affecting shipping, affecting water flow, breeding mosquitoes and flies, destroying drinking water resources, and restricting the growth of other aquatic animals and plants. [0003] Water hyacinth has a well-developed root and hair system, which has a strong enrichment effect on nitrogen, ph...
