Problems solved by technology

The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry manure will also cause soil environmental problems such as soil acidification and heavy metal residues
[0003] At present, there are several methods for the treatment of aquaculture manure, such as anaerobic fermentation method (digester), composting method or direct application as fertilizer, but the existing treatment methods all have large investment, large land occupation, secondary pollution and technical problems. Control complex and other defects
Taking the anaerobic fermentation method and composting method as examples, the required area and investment are relatively large, and the temperature and humidity need to be well controlled during the treatment. Not only is the process control difficult, the process steps are cumbersome, and the treatment time is very long (15~ 60 days), it is difficult for ordinary farmers to form a scale
On the other hand, cultured manure itself is a kind of good farmyard manure, and it is a high-quality organic fertilizer resource for fertilizing and improving the soil. However, if the manure is directly applied, it will inevitably have negative effects such as crop root damage, disease, and weed damage.
Due to the limitations of many factors, most of the farmers in our country cannot make good resource utilization of the breeding manure.
[0004] In order to simplify the operation procedure for the treatment of breeding manure and improve the process efficiency of the treatment of breeding manure, a variety of treatment equipment for breeding manure is disclosed in the prior art, but most of the existing treatment equipment is static fermentation equipment, and the structure is relatively complicated , the feed and discharge are not smooth, the fermentation time is long, and the fermentation effect is not ideal, it is difficult to meet the needs of farmers for large-scale treatment of breeding manure

Embodiment

[0031] a kind of like Figure 1 to Figure 5 The drum-type fermentation device of the present invention shown includes a feed port 1 (also serving as an air inlet), a discharge port 6, an air introduction port 4 and a fermentation device body. from figure 1It can be seen that the body of the fermentation device is cylindrical, and the exterior is a horizontal cylindrical container as a whole. There are hatches at both ends of the body of the fermentation device to facilitate inspection and maintenance. The feed port 1 is a circular interface, which is located on the upper left side of the fermentation device, and the lower part of the feed port 1 leads to the inner cavity of the fermentation device body through an inclined feed pipe 5 . The discharge port 6 is a circular interface, located on the lower right side of the fermentation device, and the discharge port 6 is provided with a block plate that can be opened and closed. The air introduction port 4 is also a circular int...

Abstract

The invention discloses a drum-type fermentation device which comprises a material inlet, a material outlet and a fermentation device body, wherein the fermentation device body comprises a first fermentation tank and a second fermentation tank which are butted mutually; at least one of the first fermentation tank and the second fermentation tank is rotatable; the butted interface part of the first fermentation tank and the second fermentation tank is arranged to be in an oppositely-rotating connection mode; the first fermentation tank and the second fermentation tank are internally provided with a first fermentation containing cavity and a second fermentation containing cavity respectively; the inner walls of the first fermentation containing cavity and the second fermentation containing cavity are both provided with spiral cutters; and the matched rotation of the first fermentation tank and the second fermentation tank enables cultivation excrement which enters the fermentation device to move from the material inlet to the material outlet or enables cultivation excrement which enters the fermentation device to be extruded from two ends to the middle part of the fermentation device. The fermentation device provided by the invention is simple in structure, convenient to operate, high in treatment efficiency, small in occupied area, short in time consumption, high in adaptability, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a fermenting device, in particular to a fermenting device which can be used for the treatment of breeding excrement. Background technique [0002] In recent years, the mode of raising pigs has changed from rural free-range breeding to intensive farming, and the food of pigs has also changed from the leftover hogwash to unified feed. Following this, the amount of pig manure is huge, and the excrement is harmful to the environment. pollution is becoming increasingly serious. The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry manure will also cause soil environmental problems such as soil acidification...
