Description
Technical Field
The invention belongs to the technical field of livestock breeding, and particularly relates to a dung leaking plate and a preparation method thereof.
Background
At present, the animal husbandry in China is in the key period from the traditional animal husbandry to the accelerated transformation of the modern animal husbandry, and various contradictions and problems are highlighted: the potential safety hazard of the quality of animal products is prominent, the prevention and control situation of epidemic diseases is severe, the market fluctuation of animal products is aggravated, and the overall production technology level is laggard. The contradiction and the problems are mainly low in organization, scale and standardization level, poor in improved variety breeding system and mechanism, not firm in animal husbandry development foundation and incapable of meeting the requirements of modern animal husbandry development. Therefore, a key link must be grasped, the acceleration of the standardized scale cultivation and the establishment of an improved variety breeding system of the livestock and poultry is taken as an entry point for dissolving the development bottleneck of the modern animal husbandry, which is also a long-term and arduous task and has very important significance for promoting the continuous and healthy development of the animal husbandry.
Promotes the standardized scale cultivation of livestock and poultry and the construction of an improved variety breeding system, and is an important guarantee for stabilizing the supply of livestock products. Solves the consumption problem of meat, eggs and milk of more than 13 hundred million people, ensures stable supply, and is the first major development of animal husbandry. The standardized large-scale livestock farm has large investment and strong market risk resistance, improves the large-scale breeding proportion, and is an important basis for enhancing the comprehensive production capacity of the animal husbandry and ensuring the stable supply of animal products. Meanwhile, the construction of an improved variety breeding system is enhanced, an improved variety breeding mechanism is perfected, the dependence on foreign excellent variety import is reduced, the stable supply of excellent seed sources is ensured, and the stable supply of animal products can be effectively promoted.
In 2019, due to the influence of factors such as 'pig cycle' descending, impact of African swine fever epidemic situation, improper feeding and limited breeding in some places and the like, the yield of nationwide live pigs in 2019 is reduced more, and the price of the pigs is increased greatly. According to the data of the national statistical bureau, the number of stored pigs in 2019 is 31041 ten thousand, which is reduced by 27.5% compared with the number of stored pigs in the last year, and the number of discharged pigs in all years is 54419 ten thousand, which is reduced by 21.6% compared with the number of stored pigs in the last year. Sichuan province is a big province for pig breeding, and the yield of pigs in 2019 is 4852.6 ten thousand, which is reduced by 26.9% compared with the last year. The 6000 million live pigs in 2020 of Sichuan province have serious target for marketing, and the new construction of a large centralized pig farm is urgent.
The dung leaking plate is an important building device of a centralized farm, and is a most used type of waste nutrient separating device in a sewage circulating system of each farm. The materials of the dung leaking plate are mainly four types of wood, PC plastic, metal and reinforced cement in the market. The quality of the excrement leaking plate made of wood materials is the worst, the service life is about 3 years under the corrosion of long-term corrosive solid-liquid excrement, and the plate is basically eliminated by the market at present. The PC plastic dropping board has advantages in manufacturing process and processing speed, but has disadvantages in upper bearing capacity and aging resistance, so that the PC plastic dropping board has high utilization rate in the breeding process of small livestock (such as chicken, duck, goose and the like), and has very low utilization rate in the breeding process of large livestock (such as pig, cow and the like). The metal excrement leaking plate has obvious disadvantages in corrosion resistance, cost and dead weight. Most of the metal materials commonly used in the market are alloy steel materials, for example, special alloy steel can counteract part of the manure corrosion, but the cost is high, and the acid corrosion of the manure and the liquid electrolysis can gradually develop the crystal structure in the alloy in the long-term use process, so that iron rust is generated, and the poultry on the manure leaking plate is scratched; if the common alloy steel is adopted for manufacturing, the corrosion resistance of the excrement leakage plate can not reach the standard. And steel deadweight is great, and is very big to the load of major structure when the plant builds multilayer swinery, and the construction unit has to adopt more cost to strengthen the bearing capacity of major structure. Therefore, the reinforced cement excrement leaking plate becomes the final choice of most concentrated pig farms. In the manufacturing process of the reinforced cement leak board, the use of raw and auxiliary materials adopts GB175-2007 general portland cement, JGJ52-2006 sand and stone requirements and GB1499.2-20071 deformed steel bar requirements; the manufacturing process adopts the manufacturing requirements of GB1499.2-2007 reinforced concrete, thereby achieving a plurality of indexes on the structure and the structure of the dung leaking plate.
The reinforced cement dropping board is mainly adopted in the large-scale pig breeding in China, and can be used as a main building material and equipment of a centralized pig farm to occupy the market in a very long period of time in the future. The existing reinforced concrete excrement leaking plate has the advantages of low cost, simple manufacture, good corrosion resistance and the like, but the defects of low surface flatness and poor compactness of cement concrete exist all the time. The flatness of the cement excrement leaking plate directly influences the effect of excrement leaking discharge, the compactness of cement concrete influences the cleaning and disinfecting effect, if the air in the cement excrement leaking plate is not exhausted during pressing, a honeycomb is easily formed on the surface of the excrement leaking plate, the honeycomb is called as a honeycomb plate in the industry, the strength of the honeycomb plate is greatly reduced, excrement residues can be remained, the cleaning and disinfection are incomplete, and the breeding risk is brought. When the discharge and the disinfection effect of the African swine fever germs are poor, a large amount of breeding is most easily carried out on residual excrement and urine, once epidemic outbreaks occur in a closed concentrated pig farm, the social and economic losses are unpredictable.
