Description
Technical field
The utility model belongs to livestock environment engineering field, is related to a kind of closed animal house with underground and scrapes excrement and automatic manure-cleaning
System.
Background technique
Cleaning up excrement is a main contents of Animal husbandry production management and the weight of waste comprehensive treatment and livestock environment regulation
Want one of link.Current animal husbandry mostly uses that water rushes excrement, three kinds of modes of bubble excrement and dry cleaning up excrement carry out cleaning up excrement, and water rushes the labour of excrement
Intensity is small, and cleannes are high, but water consumption is huge, and sewage yield is high；Bubble excrement rushes excrement compared to water and reduces water consumption, but easy to ferment
Pernicious gas is generated, and immersion causes nutriment to be lost to excrement for a long time in urine and water, reduces dung recovery exploitation value
Value；Dry cleaning up excrement has manually dry cleaning up excrement and two kinds of mechanical dry cleaning up excrement, and manually dry cleaning up excrement production efficiency is low, great work intensity, mechanical dry
Cleaning up excrement has many advantages, such as that sewage yield is few, nutrient loss is small and it is artificial to save, and is China's scale herding future cleaning up excrement technology
Prior development direction, this place are illustrated by taking pig breeding industry as an example.
The current most widely used most mature mechanical dry cleaning up excrement mode of China's large-scale pig farm is that underground type machinery scrapes excrement mould
The altitude in pig house that is mainly characterized by of formula, the mode is laid with slatted floor, and it is deep that 0.8-1.6m is built under slatted floor
Scrape dropping pit, scrape the V-shaped slope surface in dropping pit bottom surface, be equipped with sewage pipe scraping the decentralization of dropping pit bottom surface center, it is piggery feces, urine, clear
The dirts such as wash water are fallen on by slatted floor to be scraped in dropping pit, and the liquid dirts such as urine and ejected wash water pass through the gradient of V-type slope surface certainly
Sewage pipe so is flowed to, the solid state dirts such as excrement, which stay in, scrapes dropping pit bottom surface, and collects and please manage to pig house by mechanical scraper
Waste is connected by giving up outer dropping pit in the house that end, more pig houses or a plurality of dropping pit are collected, and is united using fortune dung-cart or conveyer belt
One transports to piggery waste integrated treatment region.
Pig house underground type machinery scrapes excrement mode, realizes timely cleaning and the fecaluria source separation of pig house waste, is conducive to
Pig house sanitation and hygiene are kept, the nutrient in solid manure had both been saved, and had been conducive to the recycling cropland application of excrement, also reduces
The indexs such as COD, ammonia nitrogen in sewage are conducive to the harmless treatment of sewage, are the masters of current and future China large-scale pig farm
Want one of cleaning up excrement mode.
Existing underground type machinery, which scrapes excrement pig house usually, will clear up the waste of inside pig house to outside house, therefore, in order to protect
Card scrapes operation of the excrement system in dropping pit, and She Nei is actually connected to by underground dropping pit with house external environment, however, this
Although connection meets the requirement of cleaning up excrement, there are following critical defects: 1. the closed pig house currently generallyd use being come
It says, the connection of dropping pit adversely affects environment control strip in giving up, and especially brings a negative impact to ventilating system in pig house, air-flow
Pig house should be entered by specific air inlet, but the connection of dropping pit in a disguised form increases an air inlet, very disruptive gives up interior gas
Flow distribution is unfavorable for the regulation of pig house control environment, simultaneously because the insufficient defect of pig house underground dropping pit airtightness, pig house is logical
Energy consumption needed for wind, heat preservation, heat-insulated etc. will greatly increase, expense needed for increasing pig house environment regulation；2. pig house dropping pit is usual
It is the pollutants such as the source, including foul gas, airborne microorganism, dust of pig farm pollution, dropping pit is by the connection inside and outside pig house, no
Conducive to the control of pig house outside atmosphere, environmental requirement is not met；3. connection inside and outside the house of pig house dropping pit is easy to propagate air
Pathogenic microorganism, cause between different pig houses, between pig and people, the cross infection of disease between different breeding field and epidemic disease propagate,
There are serious control and prevention of disease security risks.
Utility model content
Excrement and automatic manure-cleaning system are scraped with underground in view of this, the purpose of this utility model is to provide a kind of closed animal houses
System, fills up pig house underground type and scrapes technological gap of the excrement system in terms of environment airtightness, scrapes excrement system normal operation ensureing
On the basis of, it improves pig house environment regulation efficiency and reduces energy consumption, reduce pig farm to the air pollution degree of surrounding enviroment, control
The infection of disease price differential and diffusive transport, provide comfortable growing environment for pig, are to provide pure and fresh air environment around pig farm,
Realize the energy-saving and environmental protection and safety of pig production.
In order to achieve the above objectives, the utility model provides the following technical solutions:
A kind of closed animal house scrapes excrement and automatic dung cleaning system with underground, comprising: herding house, the herding house by ceiling,
