Abstract

The utility model discloses a temperature control device for organic fertilizer fermentation, which is provided with a fermentation tank. A blower fan is arranged below the fermentation tank, and a temperature sensor is arranged in the fermentation tank. The temperature sensor is connected with a data processor which is connected with the switch of the blower fan; simultaneously, the switch of the blower fan is connected in parallel with a time controller. The utility model can replace the heavy pile turning work in the organic fertilizer fermentation production, and has the advantages of simple structure and low running cost. In addition, the utility model can effectively decrease the production cost and realize the industrial production of organic fertilizer.

Description

A kind of automatic temp controller that is used for the fertilizer fermentation

Invention field the utility model relates to organic fertilizer fermenting apparatus, especially refers to a kind of automatic temp controller that is used for the fertilizer fermentation.

Background of invention forced ventilation static compost is to make organic materials mineralization, humification and the innoxious method that becomes the organic commercial fertilizer material by thermophilic fermentation under microbial process.Compost is a biological procedures, the key of composting production fertilizer is the normal procreation of microorganism, carry out smoothly in order to make composting, must build an environment that helps microbial reproduction and it is played one's part to the full, wherein, the regulation and control of temperature and ventilation are two important environmental factors that influence compost.The traditional temperature and the control of ventilation mainly adopt artificial or mechanical turning to realize, or back and forth walk along the fermenter length direction by stirrer, and fertilizer is stirred in rotation, as shown in Figure 1, make them constantly form the space, guarantee that the temperature of composting process is even, the oxygen abundance.The former labour intensity is big, latter's apparatus expensive, maintenance of equipment expense height.

The summary of the invention the purpose of this utility model provides a kind of simple in structure, the organic fertilizer fermenting apparatus of A.T.C.

The utility model is realized in the following manner: organic fertilizer fermenting apparatus is provided with fermenter, and fermenter is provided with blower fan, temperature sensor, and wherein temperature sensor connects data handler, and data handler connects with the switch of blower fan.

Adopt above structure, can replace turning work heavy in the fertilizer fermentative production.This apparatus structure is simple, and working cost is low, can effectively reduce production costs, and can realize the fertilizer suitability for industrialized production.

Description of drawings now is further elaborated the utility model in conjunction with the accompanying drawings.

Fig. 1 is existing organic fertilizer fermenting apparatus synoptic diagram;

Fig. 2 is the utility model structural representation;

Fig. 3 is the utility model temperature control synoptic diagram;

Fig. 4 is the utility model time control synoptic diagram.

Specific embodiment is shown in Fig. 2,3,4, organic fertilizer fermenting apparatus of the present utility model is provided with fermenter 1, and fermenter 1 has blower fan 2, is provided with temperature sensor 3 in the fermenter, temperature sensor 3 connects data handler 4, and data handler 4 connects with the switch 5 of blower fan 2.Temperature rises when 8 fermentations of the heap of the fertilizer in the fermenter 1, and temperature sensor 3 records the temperature of

fermentation heap

8, and 4 pairs of measured temperature of data handler are judged.When the medial temperature that records fertilizer heap 8 when data handler was higher than 60 °, the switch 5 of blower fan 2 started, and (air quantity is per minute 0.25m in the blower fan non-stop run ³), disperse heat by piling 8 air blast to fertilizer, reaching, increase oxygen, reduce the purpose that fertilizer is piled 8 temperature, prevent the restraining effect of high temperature to organism of fermentation; Piling 8 temperature when fertilizer descends, when the average temperature that temperature sensor 3 records fertilizer heap 8 is lower than 60 °, in order to offer fertilizer heap 8 an amount of oxygen, the switch 5 of blower fan 2 is a time controller 6 in parallel simultaneously, and time controller 6 is set per 4 hours startup blower fans, and (air quantity was per minute 0.25m in 20 minutes ³) pile 8 oxygen supplys to fertilizer, promote the purpose of fertilizer fermentation to promote the aerobic fermentation of fertilizer heap 8, to reach to heat up, carry out and so forth finishing until the fertilizer thermophilic fermentation stage.
