Problems solved by technology

[0003] However, the production of yak dung fuel in daily life is usually done by herdsmen women directly collecting wet yak dung, stirring fresh yak dung directly by hand, and making cow dung cakes like making dough cakes. The dung cake is loose, the storage time is short, and the production is labor-intensive

Embodiment 1

[0016] A method for preparing mixed fuel is a method for making domestic fuel from yak dung, which is realized through the following steps:

[0017] (1) Collection of cow dung: collect fresh cow dung in pastoral areas in summer and autumn, and store them centrally;

[0018] (2), ingredients: take 70 parts of fresh cow dung, 20 parts of grass chaff, 10 parts of clay, and fully stir them evenly;

[0019] (3), forming: the mixture obtained through (2) step is extruded under the pressure of 60kg-70kg, such as square (side length 20cm * 20cm);

[0020] (4) Drying: place the material obtained through the step (3) on the lawn on the sunny slope of the pasture or on the drying field, and expose it to the sun for 1d-2d to obtain the finished product.

Embodiment 2

[0022] A method for preparing mixed fuel is a method for making domestic fuel from yak dung, which is realized through the following steps:

[0023] (1) Collection of cow dung: collect fresh cow dung in pastoral areas in summer and autumn, and store them centrally;

[0024] (2), ingredients: take 60 parts of fresh cow dung, 30 parts of grass chaff, 10 parts of clay, and fully stir them evenly;

[0025] (3), forming: the mixture obtained through (2) step is extruded under the pressure of 60kg-70kg, such as square (side length 20cm * 20cm);

[0026] (4) Drying: place the material obtained through the step (3) on the lawn on the sunny slope of the pasture or on the drying field, and expose it to the sun for 1d-2d to obtain the finished product.

Embodiment 3

[0028] A method for preparing mixed fuel is a method for making domestic fuel from yak dung, which is realized through the following steps:

[0029] (1) Collection of cow dung: collect fresh cow dung in pastoral areas in winter and spring, and store it centrally;

[0030] (2), sieving: sieve coal cinder with civil sieve, remove the coal cinder of large particle;

[0031] (3), crushing: the cow dung is crushed into particles smaller than 0.1cm;

[0032] (4), batching: take 60 parts of pulverized cow dung, 30 parts of straw bran, 10 parts of cinder, and fully stir evenly;

[0033] (5), forming: the mixture obtained through (4) step is extruded under the pressure of 60kg-70kg, such as square (side length 20cm * 20cm);

[0034] (6) Drying: place the material obtained through the step (5) on the lawn on the sunny slope of the pasture or on the drying field, and expose it to the sun for 1d-2d to obtain the finished product.

Abstract

The invention discloses a preparation method of a mixed fuel. The method comprises the following steps: (1) collecting faeces of yaks, namely collecting faeces of yaks and putting the faeces in a place sheltering from rain; (2) screening, namely screening coal cinders by a sieve and removing large-particle coal cinders; (3) crushing, namely crushing the faeces of yaks collected in spring and winter into particles which are smaller than 0.1cm, and ensuring that the faeces of yaks are not crushed in summer and autumn; (4) proportioning, namely fully and uniformly stirring 50-80% of fresh faeces of yaks, 0-10% of grass bran and an adhesive; (5) forming, namely adding a proper amount of water into the mixture prepared by the four steps and forming at a low pressure of 60-80kg; and (6) insolating the substances obtained by the five steps for 1-2 days to prepare a finished product. The preparation method disclosed by the invention has the characteristics of being energy-saving, environmentally friendly, and convenient and sanitary to prepare, and can be used for solving the problems that the handmade fuel of faeces of yak prepared by herdsmen is sparse, short in storage time and great in preparation labor intensity.

Description

technical field [0001] The invention relates to a method for preparing mixed fuel, in particular to a method for preparing mixed fuel for herdsmen's life based on fresh cow dung. Background technique [0002] The Qinghai-Tibet Plateau is the place with the highest average altitude in the world, with an average altitude of over 4km, and its oxygen concentration is only 75% of that in low-altitude areas. The combustion process of fuel requires oxygen to participate in combustion, and low-concentration oxygen will exist for general fuels Incomplete combustion due to lack of oxygen. Yak dung plays an irreplaceable role in the life of herdsmen on the Qinghai-Tibet Plateau: First, after the viscous components of yak dung are digested and absorbed by yaks in the body, the remaining fibrous material is loose and transparent, which increases the contact area with the air and makes the burning Completely and thoroughly, it is the rare best fuel; secondly, the Qinghai-Tibet Plateau ha...
