Description

TECHNICAL FIELD [0001] The present invention relates to a solid fuel producing apparatus using a livestock excrement,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid fuel producing apparatus, and more particularly, to an apparatus for producing a solid fuel using excretions of cattle such as cattle, chickens, and pigs.

Livestock excreta refers to poop and urine excreted by livestock such as cows, pigs, and chickens. As the demand for livestock products grows along with the economic growth, the number of cattle that have been raised in single livestock facilities is gradually increasing,

Since the livestock feces contains various organic compounds and fertilizer components such as nitrogen, phosphoric acid and potassium, it is used as fertilizer in crops and fruit trees. However, since the amount of fertilizer is too much, It is becoming a source of development. If you leave the animal excrement still, it will cause bad smell and become a habitat for various insects such as flies and mosquitoes, which will make the living environment worse. If it is released with rainwater or water cleaned, it becomes livestock wastewater.

In Korea, the amount of livestock excreta was about 60kg per day (40kg of poison, 20㎏ of poison), 22.5kg of poisonous herb (15kg of poison, 7.5㎏ of poison), 7.7㎏ of domestic pig (2.7kg of poison, 5 kg of urine) and 0.15 kg of edible chicken. The rate of incidence of cattle manure is 60.3%, pig manure is 32.6%, and weights are about 8.15%. Of these, 90% or more of the flora is used for dry or rotten manure, but it is estimated that cow and pig shit are recycled to less than 15%.

In order to minimize composting of excrement and to minimize the inflow of water into the river by rainwater to reduce the amount of pollution load, the pollutant load of the water system due to livestock wastewater mixed with water is equivalent to about 20% However, it is known that efficiency is low in terms of space utilization and cost input. Therefore, it is necessary to study more effectively the livestock excrement.

The hopper 100 may be formed in various shapes. However, the hopper 100 may be provided with a crushing blade portion 210 and a slurry moving screw portion 220, and may be formed into a generally rectangular shape so as to receive as much slurry as possible And it is preferable that the upper part is formed in a narrow shape (see FIG. 7) so that the excretion can be easily discharged through the discharge port 110 of the hopper 110. Therefore, the hopper 100 of the present embodiment is formed such that the opened upper surface is wide and the lower surface is narrowed as shown in FIG.

The excrement moving screw portion 220 is disposed below the crushing blade portion 210 so as to move the excrement stirred by the crushing blade portion 210 to the discharge port 110.

In the lower part of the hopper 100, a fuel generating unit 300 for solidifying the excrement moved through the discharge port 110 to solidify the excrement is installed.

Therefore, the excrement contained in the hopper 100 is stirred by the crushing blade part 210, and the moisture contained in the excrement is uniformly maintained in the direction of the excrement moving screw 220, And the discharged fecal matter is compressed and solidified in the fuel generating unit 300, thereby forming a solid fuel.

It is preferable that the pulverizing blade 210 is configured to occupy a large area inside the hopper 100 so as to effectively stir the excrement contained in the hopper 100. Therefore, As shown in FIGS. 1 and 2, the pulverizing blade shaft 210 includes a pulverizing blade shaft 211 rotatably disposed on opposite sides of the hopper 100, And a plurality of crushing blades 213 so as to occupy a large area inside the hopper 100 across the mutually facing side surfaces in the hopper 100.
