SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a livestock and poultry breeding excrement aerobic humus device solves the stink that current traditional anaerobic fermentation and aerobic fermentation technique exist big, produce marsh gas potential safety hazard, moisture and scatter and disappear fast, the heat loss is big, equipment operation is difficult, technical requirement height problem.

The above technical purpose of the present invention can be achieved by the following technical solutions: the device for the aerobic humification of the livestock and poultry breeding manure is characterized in that: including good oxygen humus jar, heat energy converter, solar energy power conversion device, good oxygen humus jar is close to the bottom position and has seted up the excrement discharge mouth, good oxygen humus jar is connected with the heat energy converter, a electrolysis trough is connected to good oxygen humus tank bottom, solar energy power conversion device is connected with the electrolysis trough, good oxygen humus jar communicates with the electrolysis trough and locates to install the support layer at the intercommunication.

Preferably, the thermal energy converter adopts an air energy heat pump and/or a vacuum tube solar water heater.

Another object of the utility model is to provide a dirty good oxygen humification system of excrement, dirty good oxygen humification system of excrement adopts two beasts and birds to breed the good oxygen humification device of excrement and moves in turn.

To sum up, the utility model discloses following beneficial effect has: (1) the utility model discloses utilize the beasts and birds excrement to dirty carry out high temperature aerobic composting, both solved the dirty processing problem of excrement, can obtain the fertilizer that is applicable to agricultural land production, fruit tree planting and afforestation again, to lightening the farmland environmental pollution that the chemical fertilizer caused of using for a long time, increase soil fertility, improve the agricultural product quality and increase agricultural income, all have good economic benefits, environmental benefit and social.

(2) Compare with the microbial community natural succession process of traditional low temperature aerobic composting in-process, the utility model discloses carry out high temperature aerobic biological humification in aerobic humification device, can provide suitable ambient temperature for the high temperature aerobic microorganism of compost, show the ability of accelerating microorganism growth rate and degradation or conversion organic matter, not only can accelerate compost reaction rate, make the dirty humification time of excrement shorten to 4 days, also can save the compost cost greatly, show to improve sanitary environment.

(3) Compared with aerobic fermentation, the traditional high-temperature anaerobic fermentation technology for the excrement takes longer time, the odor generation amount in the fermentation process is large, and potential safety hazards exist in the generated methane. The technology needs professional operators, is suitable for large-scale breeding enterprises, and has low applicability to a large number of rural small-sized breeding specialized households and free-ranging households in the famous region. The utility model provides a high temperature aerobe humation technique, odorless tasteless no potential safety hazard, equipment easy operation, it is with low costs, big small and big type raiser all can use.

(4) The traditional high-temperature aerobic fermentation technology for the excrement has the defects of large air supply rate, large moisture and heat loss, mechanical stirring, complex equipment, difficult control of the relation between the appropriate moisture and the air supply rate for general farmers, and the excrement water film can obstruct the oxygen mass transfer process of an air supply system to generate short flow. The utility model discloses carry out the in-process of the good oxygen biological humification of high temperature in the good oxygen humification device, need not the ventilation stirring, can control moisture, not only great reduction the operation degree of difficulty, still improved holistic efficiency.

(5) The utility model discloses carry out the in-process of the good oxygen biological humus matter of high temperature in the good oxygen humus matter device, adopted inoculation fungus liquid (high temperature good oxygen fungus liquid) technique, organic matters such as crude protein, crude fat, residual starch and urea in this fungus liquid high efficiency degradation beasts and birds excrement is dirty can accelerate degradation or the conversion rate of above-mentioned organic matter in the compost raw materials greatly like this, promotes the compost process, improves compost efficiency.

(6) The utility model discloses based on high temperature aerobic composting technique and ripe solar energy, air energy heat pump technique, solar energy electrolysis water oxygen suppliment technique, constructed novel beasts and birds and bred the excrement and dirty security, humate and fertilizied new technology of handling, investment cost is lower, safer, change operation and maintenance.
