Description

Technical Field

[0001] The invention belongs to the technical field of machine-made charcoal preparation, and specifically refers to a process for producing machine-made charcoal by drying manure and fermented mattress materials in a breeding farm. Background Art

[0002] Mechanism charcoal is also known as firewood stick, artificial charcoal, smokeless charcoal, and clean charcoal. Due to its many advantages such as being flammable, smokeless, odorless, non-toxic, and non-explosive, it has been widely used for home heating and barbecue food. In contrast, charcoal prepared by general processes has a short burning time and low calorific value, which does not meet the requirements of energy conservation and environmental protection. Mechanism charcoal has a high calorific value, long burning time, low ash content, and is smokeless, and is deeply loved by people. Traditional mechanism charcoal production uses resources such as forests and bamboo forests as raw materials, and has a high demand for wood. When the output increases, on the one hand, the supply of raw materials will be insufficient. On the other hand, the large-scale use of wood will also cause a large consumption of the ecological environment, which does not meet the requirements of environmental protection; and the traditional process of making mechanism charcoal requires a large amount of heating equipment, which not only consumes a lot of energy, but is also not conducive to environmental protection. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a process for producing charcoal by drying manure and fermented mattress materials in farms, which changes the traditional way of producing charcoal, broadens the source of raw materials for producing charcoal, realizes waste utilization, and effectively reduces energy consumption. It uses animal manure supplemented with fermented mattress materials in farms for fermentation, solves the manure problem in pig (poultry) farms, and at the same time reduces the use of wood, effectively reduces energy consumption, and achieves the purpose of energy saving and emission reduction.

[0004] On the one hand, the present invention provides a process for producing charcoal by drying manure and fermented mattress materials in farms, which includes fermentation raw materials, including the following components: 3 to 5 parts of sawdust, 3 to 5 parts of rice husks, and 3 to 5 parts of straw.

[0005] In another aspect, the present invention provides a method for producing charcoal by drying manure and fermented mattress materials in a farm, comprising the following steps:

[0006] S1. Take the fermentation raw materials of the above components, screen and remove impurities, and crush the raw materials;

[0007] S2, using the raw material as a fermentation mattress material, assisting with the fermentation bed special strains to ferment and absorb the protein and crude fiber in the animal feces, the strains have the characteristics of heating and digesting protein, after 90-360 days of decomposition and fermentation, the protein in the animal feces is basically digested, and there is no obvious irritating odor, the bacteria generate heat during digestion, and the effect of drying the bedding is achieved, the protein in the raw material is greatly reduced, and the lignin in materials such as sawdust is not lost during this period. During the process, the moisture content of the bedding is significantly reduced by the continuous operation of the rake turning machine in the fermentation bed, and the moisture content is reduced to 40%-60%. At this time, the effect of controlling water and eliminating eggs (protein) is achieved, and the material basically has the conditions for carbon production;

[0008] S3. In order to improve production efficiency and reduce production costs, the fermented bedding and sawdust are mixed, the two are combined in a certain ratio, and sent to a rod making machine to make hollow firewood sticks, and then the firewood sticks are placed to cool naturally;

[0009] S4, putting the firewood into the carbonization furnace for heating, under anaerobic conditions, first controlling the temperature at 120-150°C to dry the firewood for 20-30 hours; then controlling the temperature at 200-300°C to perform preliminary carbonization on the firewood, maintaining for 60-70 hours; then under anaerobic conditions, controlling the temperature at 750-850°C to calcine the firewood, maintaining for 8-12 hours, and then naturally cooling to room temperature under anaerobic conditions to obtain machine-made charcoal;

[0010] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a process for producing charcoal by drying the fermented bedding material in a farm, and uses fermentation to replace the traditional technology of drying the bedding material through drying equipment. The heat generated by the bacteria during digestion during the fermentation process dries the bedding material, which greatly reduces the protein in the raw materials. At the same time, the lignin in materials such as sawdust is not lost during this period, so that the bedding material has the basis for making charcoal, and charcoal can be made in combination with sawdust. This solution utilizes the animal manure fermentation process, which can solve the problem of farm manure treatment on the one hand, and simplify the process of making charcoal on the other hand, reducing energy consumption, and achieving a dual environmental protection and energy-saving effect. DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0012] Example

[0013] The present invention provides a charcoal production process by combining manure with fermented mattress material in a breeding farm and drying the fermented mattress material. The fermented raw materials include the following components: 5 parts of sawdust, 3 parts of rice husks, and 3 parts of straws. The main components are combustible materials such as sawdust, rice husks, and straws. Each breeding farm can make flexible adjustments based on the current market price of the raw materials for the fermented mattress material so as to reduce production costs and improve economic benefits.

[0014] This embodiment provides a method for producing charcoal by drying manure and fermented mattress materials in a farm, comprising the following steps:

[0015] S1. Take the fermentation raw materials of the above components, screen and remove impurities, and crush the raw materials;

[0016] S2, using the raw material as a fermentation mattress material, assisting with the fermentation bed special strains to ferment and absorb the protein and crude fiber in the animal feces, the strains have the characteristics of heating and digesting protein, after 90-360 days of decomposition and fermentation, the protein in the animal feces is basically digested, the bacteria generate heat during digestion, and the effect of drying the bedding is achieved, the protein in the raw material is greatly reduced, and the lignin in materials such as sawdust is not lost during this period. During the process, the moisture content of the bedding is significantly reduced by the continuous operation of the rake turning machine in the fermentation bed, and the moisture content is 40%-60%. At this time, the effect of controlling water and eliminating eggs (protein) is achieved, and the material basically has the conditions for carbon production;

[0017] S3, mixing the fermented bedding and sawdust, combining the two in a certain ratio, and sending them to a rod making machine to make hollow firewood sticks, and then placing the firewood sticks to cool naturally;

[0018] S4, putting the firewood into the carbonization furnace for heating, under anaerobic conditions, first controlling the temperature at 120-150°C to dry the firewood for 20-30 hours; then controlling the temperature at 200-300°C to perform preliminary carbonization on the firewood, maintaining for 60-70 hours; then under anaerobic conditions, controlling the temperature at 750-850°C to calcine the firewood, maintaining for 8-12 hours, and then naturally cooling to room temperature in anoxic conditions to obtain machine-made charcoal;

[0019] In the embodiment, in S3, the sawdust may be fresh sawdust, old sawdust, or other materials rich in lignin.

[0020] Among them, in step s3, in the process of mixing the padding and sawdust, the two are combined in ten groups according to the following proportions, namely: 100% padding, 90% padding and 10% sawdust, 80% padding and 20% sawdust, 70% padding and 30% sawdust, 60% padding and 40% sawdust, 50% padding and 50% sawdust, 40% padding and 60% sawdust, 30% padding and 70% sawdust, 20% padding and 80% sawdust, and 10% padding and 90% sawdust.

[0021] At present, the industry mainly uses two indicators to determine the quality of machine-made charcoal: caloric content and ash content. After testing, as shown in Table 1.

[0022] Table 1

[0023]

[0024] analyze:

[0025] In the first group, the litter was 100%, the experimental effect was poor, it was difficult to ignite, the combustion was not complete, and the combustion value did not meet the qualified requirements of the charcoal industry;

[0026] In the fourth group, the bedding material is 70% sawdust and the other is 30%. When the machine-made charcoal is made with the ratio of 70% bedding material and 30% sawdust, the finished product has better combustion effect and burns more completely than the first group. The heat is obviously changed and basically reaches the qualified level of the machine-made charcoal industry. However, considering factors such as the quality of the finished product, market economic benefits, and environmental protection, enterprises or individuals can appropriately adjust the proportion of sawdust according to their own production needs, improve the market competitiveness of products, and thus effectively increase economic benefits.

[0027] In the sixth group, the litter was 50% sawdust and 50% sawdust. The experimental effect was significantly improved. It was easier to ignite than the experimental example 3, the combustion value was significantly improved, and all indicators could reach the industry's medium standards.

[0028] in conclusion:

[0029] Through 10 groups of comparative experiments, it is concluded that when the base material is 70% sawdust and 30% sawdust, as the sawdust ratio continues to increase, the effect of the produced charcoal will become better and better. Considering the economics and relieving the pressure on the environment, supplemented by the experimental results, we conclude that when the sawdust ratio is between 30% and 50%, it is the most economical ratio for making charcoal, and it can also bring better environmental treatment efficiency.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0031] The present invention and its implementation methods are described above, but such description is not restrictive, and what is shown is only one of the implementation methods of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
