Accompanying drawing is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
With reference to accompanying drawing, a kind of organic waste aerobic compost testing apparatus comprises fermentor tank 7; There is agitator motor 2 fermentor tank 7 tops, and agitator motor 2 is sling by hanging wheel 1, but free lifting; Make things convenient for the installation and removal of sealing cover 4, the stir shaft 13 in the fermentor tank 7 passes sealing cover 4 and is connected with agitator motor 2, and sealing cover 4 is provided with form 3; Can observe material situation in the fermentor tank 7 through form 3, fermentor tank 7 is installed on the fixed bias circuit 6, can rotate freely front and back; Make things convenient for the material turnover, temperature is by 3 groups of TP 5 The real time measure that are installed in fermentor tank 7 both sides in the fermentor tank 7, and TP 5 all is connected with PLC control module 19 with gas detector 18; PLC control module 19 links to each other with computer 20, is provided with thief hole 12 in the middle and lower part of fermentor tank 7, is communicated with air compressor machine 9, temperature control unit 8 in fermentor tank 7 bottoms and is provided with percolate drain 10; Fermentor tank 7 inner belows are provided with air distribution plate 11, and by the 11 even gas distributions of the air distribution plate below fermentor tank 7 inside, sealing cover 4 is provided with venting port 14 to the air that air compressor machine 9 produces in fermentor tank 7; Venting port 14 is connected with detecting box 16 interior cooling driers 17; Also be communicated with condensate collector 15 on the branch road of venting port 14, the small portion of discharging gas gets into detecting box 16, carries out check and analysis through getting into gas detector 18 again after cooling driers 17 dryings; Deflated is most of outdoor through draining into behind the condensate collector 15; Detect the temperature data and the gas detector 18 that obtain by TP 5 and detect gaseous fraction data process PLC control module 19 demonstration in real time on computer 20 that draws, and release, realized the long-range testing data of checking through network.
Said fermentor tank 7 is cylindrical, and top seal lid 4 is circular, processes by double-layer stainless steel, in the middle of double-layer stainless steel, is filled with perlite as thermal insulation layer.One big latex sealing-ring is arranged on the sealing cover 4,12 fixed orificess are arranged at the periphery of sealing cover 4.The top of fermentor tank 7 is a material import and export, sealing cover 4 is covered sealing after inserting material, and is through fixed orifices that sealing cover 4 sealings are tight with screw again.
After the TP 5 of said fermentor tank 7 both sides inserts fermentor tank 7 inside, add the latex packing ring and screw down, avoid gas leakage.
The air distribution plate 11 of said fermentor tank 7 inner belows is processed by the stainless steel perforation plate; Fermentor tank 7 inside are separated into two zones; Top is the compost material reaction zone, and the bottom is cloth gas area and percolate storage area, regularly through percolate drain 10 percolate is discharged.
Said stir shaft 13 lower ends are placed in the semi-circular recesses of fermentor tank 7 bottom central, and stir shaft 13 upper ends are connected with agitator motor 12 through the circular hole of sealing cover 4 central authorities.Stir shaft 13 can be realized regularly, stepless speed regulation control.
Principle of work of the present invention is:
Agitator motor 2 is sling by hanging wheel 1, but free lifting makes things convenient for the installation and removal of sealing cover 4; Stir shaft 13 is realized regularly, stepless speed regulation control; Fermentor tank 7 tops are material import and export, and fermentor tank 7 medium positions have fixed bias circuit 6, utilize rotation axis 6 that fermentor tank 7 is fixed on the top of the shelf; Fermentor tank 7 rotates before and after can doing through this axle, makes things convenient for material turnover in the fermentor tank 7.Compost material after getting into fermentor tank 7 covers sealing cover 4 completely, can observe a jar interior material situation through form 3, and the gas in the fermentor tank 7 is discharged through this venting port 14.One perforation stainless steel plate is arranged below fermentor tank 7 inside; As air distribution plate 11; Air is evenly distributed in the compost material by air distribution plate 11 after being controlled at design temperature through temperature control unit 8; The leachate collection that material produces during the fermentation and can be discharged by water port below the perforation stainless steel plate.In fermentor tank 7 both sides three TPs 5 are arranged respectively, the temperature data that records can show and release through network in real time.These six TPs 5 are active, and it is inner in composting process, TP 5 to be inserted material, when turning is stirred, can easily TP 5 be extracted.In the middle and lower part of fermentor tank 7 thief hole 12 is arranged, can from fermentor tank 7, take a sample, analyze, detect easily through thief hole 12.After gas in the fermentor tank 7 was discharged by venting port 14, small portion got into detecting box 16 and carries out oxygen and carbon dioxide content analysis, and remaining gas is outdoor through draining into behind the condensate collector 15.Because moisture content is very high in fermentor tank 7 expellant gas, this condensate collector 15 can collect expellant gas water of condensation in pipeline, avoids flowing into fermentor tank 7, reduces moisture content in the compost material.Get into that part of gas of detecting box 16, at first pass through cooling driers 17, the steam coagulation Cheng Shui of gas; Settle down; Get into gas detector 18 again and analyze, oxygen that records and carbon dioxide content data and temperature data are presented on the computer 20 through PLC control module 19 in real time, and release through network; Realize the long-range gaseous fraction in heap temperature and the exhaust of checking, but the detection time through PLC control module 19 design temperatures and gaseous fraction at interval.
Experimental teaching and scientific research that the present invention can be the organic waste aerobic compost provide good testing apparatus, but real-time online detects the content of heap temperature and oxygen and carbonic acid gas, and can long-rangely consult data whenever and wherever possible, and multiple functional, effect is remarkable.
