Description

Small-sized Composter

Technical field

The utility model relates to a kind of small-sized Composter that carries out the organic waste aerobic compost, also is applicable to the Composter of laboratory study composting process controlled variable.

Background technology

Aerobic compost is to utilize microorganism to decompose the method that organic waste is produced fertilizer under aerobic conditions.Because action of microorganisms is closely related with the temperature and humidity condition, therefore, the temperature and humidity of control composting process is the key that compost is carried out smoothly.At present, generally be no more than the top temperature of setting by the Ventilation Control heap temperature, but because composting material and pile the different of body, compositing system is not the high temperature requirement that can both reach aerobic compost.Particularly small-sized composting arrangement, because specific surface area is big, heat scatters and disappears fast, and simple heat-retaining condition is difficult to guarantee that the heat of its generation keeps normally carrying out of compost, and especially under the envrionment conditions of cold, composting process is difficult for keeping.Existing small-sized composting arrangement is not generally considered the backflow and the collection of moisture in the composting process simultaneously; And equipment component is by being used to catchment the working method that these structures need be special, operation inconvenience at its insulation can inwall or reactor wall welding cannelure.

Summary of the invention

The purpose of this utility model is to provide a kind of small-sized Composter, and this Composter can not only keep heap temperature between the bound of setting, and can realize that moisture refluxes and collection.

Comprise in order to reach the technical scheme that the purpose of this utility model takes: insulation can 2, be positioned at the reactor 6 of insulation can 2, it is characterized in that the bottom of reactor 6 is provided with well heater 1, water collector 4 is equipped with in the inside of reactor 6.

In the above-mentioned small-sized Composter, reactor 6 comprises reactor seat 3, reactor cap 5, and the outer rim of water collector 4 is provided with fin 12, and fin 12 is provided with sealing-ring 11, and water collector 4 is connected with reactor seat 3 with reactor cap 5 by its fin 12 sealing-rings.

In the above-mentioned small-sized Composter, be connected with a temperature controller 15 with the power supply of well heater 1, temperature controller 15 is connected with thermopair 8 again, forms enabling and disconnecting of Temperature Feedback Controlling System control heater 1.

In the above-mentioned small-sized Composter, fin 12 is to be welded on the outer rim of water collector 4.

In the above-mentioned small-sized Composter, two up and down of sealing-rings 11 minutes are installed in the upper and lower surface of fin 12 respectively.

It is as follows to possess the advantage that the small-sized Composter of above constitutional features has:

Since the heating system that has adopted insulation can and controlled automatically, high insulating effect, and material adaptability is strong, all can realize the high temperature high-rate composting under various envrionment conditionss; Water collector passes through the effect of welding fin, the intensity height, and only adopt the rubber ring of national standard just can reach good sealing function, water conservation is effective, can realize the collection and the backflow of moisture as required.

Fig. 2 is the sectional view of Fig. 1 water collector 4.

Fig. 3 is that the I of Fig. 1 is to partial view.

Specific embodiments

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

As shown in Figure 1, 2, 3,1 is well heater, and 2 is insulation can, and 3 is the reactor seat, 4 is water collector, and 5 is reactor cap, and 6 is reactor, and 7 is vapor pipe, 8 is thermopair, and 9 is vent-pipe, and 10 is aid distributing pipe, 11 is sealing-ring, and 12 is fin, in the present embodiment, it is the outer rim that is welded in water collector 4 by the mode of welding, and 13 be stopper, and 14 is refluxing opening, 15 is temperature controller, and 16 is under meter, and 17 is pneumatic pump.Compost material is packed in the reactor seat 3, and thermopair 8 inserts its centres, and the top and bottom of the fin 12 of water collector 4 put sealing-ring 11, and stopper 13 is filled in refluxing opening 14, cover reactor cap 5, have so just formed reactor 6; Reactor 6 is put into the insulation can 2 that has well heater 1; Be linked in sequence pneumatic pump 17, under meter 16, vent-pipe 9 and aid distributing pipe 10, and with vent-pipe 9 insertion reaction devices 6 bottoms.When envrionment temperature is low, enable well heater 1, set the bound of heap body core temperature, and pass through the feedback control signal of the core temperature of thermopair 8 mensuration as input by temperature controller 15, when temperature surpasses going up in limited time of setting, just disconnect heater power source and stop heating; Prescribe a time limit when temperature is lower than the following of setting, connect heater power source and heat; Higher when envrionment temperature, the compost self-heating causes temperature to surpass in limited time, can adopt artificial or automatic control system adjusting under meter 16 as required, increases the ventilation of pneumatic pump 17, takes away unnecessary heat.The water vapor that produces in the compost reaction process rises when touching the wall of reactor cap 5, is cooled and is back to water collector 4 rapidly along wall, can realize that by the refluxing opening 14 of opening or clog water collector 4 moisture refluxes and collects.

It should be noted last that, above embodiment only is used for the technical solution of the utility model is described and is unrestricted, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
