Abstract
The utility model provides a device for ventilating, circulating fumigating grain stacks for barns. The utility model comprises a blower and an air pipe which is connected with the blower. The air pipe is a stereo air-net pipeline which is composed of a main air pipe 7 that is connected with the blower, a plurality of branch air pipes 5 that are respectively connected with the main air pipe 7 in parallel, soft connecting pipes 2 that are respectively connected with the branch air pipes 5 in parallel, and an air outlet pipe 1 which is connected with the soft connecting pipes 2. The pipe wall of the air outlet pipe 1 is provided with a plurality of air outlet ports 16. A pipe segment which is arranged between the main air pipe and the blower is provided with an out air current accessing port 17. An air inlet port of the blower is connected with an air return pipe 14, an air suction port 13 of which is arranged above the air-net pipeline.
Description
The utility model relates to and silo is carried out ventilation drying, the device of stifling deinsectization in the storage of a kind of grain.
The ventilation of existing silo adopt mostly geosyncline, the facility of cage and so on, it is stifling that what take is fixed recirculation fumigation system.Its shortcoming is that these ventilations and fumigation apparatus all are fixed, once installation, can not move again, and air-flow is carried to the grain face from bottom to top by silo bottom, air-flow the path length of process, resistance is big, maldistribution in the grain heap is easy to generate " dead angle "; In addition, the number of times that silo is ventilated, fumigates is very limited, so the standby time of these ventilating fumigation equipment that fixedly install is many, and availability is very low.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing silo ventilation, fumigation apparatus, and a kind of ventilation is provided, and the steam stifling distributions is adjustable, and complete equipment can move soft stereoscopic ventilation of the silo of installing and using in the storehouse and device for fumigation.
Soft stereoscopic ventilation of silo and the recirculation fumigation device of realizing the utility model purpose comprise blower fan and the airduct that joins with blower fan, the air main 7 that described airduct is served as reasons and is connected to blower fan, some branch wind pipes 5 that are connected to air main 7, the three-dimensional wind webmaster road that discharge pipe 1 constitutes that is connected to the hose connector 2 of branch wind pipe 5 and is connected in hose connector 2, on the tube wall of described discharge pipe 1, have some exhaust vents 16, air main and blower fan between pipeline section on offer air-flow access port 17 outside, the air inlet of blower fan is connected to a backwind tube 14, and the inlet scoop 13 of backwind tube 14 is arranged on the top on wind webmaster road.During use discharge pipe is squeezed into from grain heap top, because the effect of hose connector, discharge pipe can be optionally and be distributed in the grain heap in modes such as vertical, oblique cuttings, branch wind pipe and air main are laid on the grain face and pick out outside the storehouse, the inlet scoop of backwind tube is located at the top of grain heap, and blower fan and outer air-flow access port are arranged in outside the storehouse.When desiring to fumigate operation, with stifling source outside the storehouse (as adopting PH
3/ CO
2Mix steel cylinder gas, PH
3/ CO
2Mixed fumigation machine dispensing or the like outside the storehouse) inserts air main from outer air-flow access port, under the effect of blower fan, should enter the discharge pipe that respectively is embedded in the grain heap through each branch wind pipe by stifling air-flow, some exhaust vents of offering from the discharge pipe tube wall come out and act on grain to pile, upper surface from the grain heap overflows then, constituted circulation cycle by the inlet scoop inspiration backwind tube of return air duct again, thereby finish recirculation fumigation operation grain.When desiring to carry out drying operation, heat air source can be inserted from outer air-flow access port, the same the same, hot blast imported in the grain heap grain is carried out drying processing.Then can discharge from the moisture that grain heap upper surface comes out by the exhaust outlet of silo.Also can be by inlet scoop inspiration backwind tube, draw outside the storehouse and leave in addition mouthful and be thrown in the atmosphere by backwind tube.As a same reason, introduce cold air and then can pile the cooling processing of lowering the temperature, repeat no more here grain.
Described discharge pipe can be made of the airduct serial connection that plurality of sections has different percent openings, does like this except being convenient to squeeze into the airduct, also can utilize the pipeline section of different percent openings to realize adjusting to the throughput that acts on grain.Can realize that moisture content, temperature, difference mould, the insect pest degree according to each position grain in the silo impose corresponding different throughput.
Join with an air distributor between described air main and each branch wind pipe, can make ventilating fumigation more air-flow be evenly distributed, fully, better effects if.
The utility model compared with prior art has the following advantages:
1, the whole wind net adopts three-dimensional form, lays flexibly with the discharge pipe of flexible pipe connection, and it is more reasonable that the air channel is arranged, air-flow is evenly distributed, but ventilates, fumigates the position regulated at will;
2, air main, branch wind pipe can be laid on the grain heap face, and blower fan, outer air-flow intake are arranged on outside the storehouse, have avoided being provided with problems such as underground ventilation, the stifling required hole capital after selling all securities of pipe network, destruction building structure;
3, package unit convenient disassembly, many storehouses wheel usefulness, the utilization rate of equipment and installations height;
4, multiple functional, operating flexibility, can be according to the operation of silo job requirements: as finish whole storehouse ventilation, local ventilation, connect the cereal electric calorifier and finish drying generator, connect grain cooling machine and finish, connect and mix steel cylinder gas and finish and fumigate etc. in the storehouse outside with regard to the storehouse cooling.
Provide embodiment below in conjunction with accompanying drawing.
The structural representation of Fig. 1 embodiment 1
The structural representation of Fig. 2 discharge pipe
The structural representation of Fig. 3 embodiment 2
Embodiment 1:
Referring to Fig. 1, formation of the present utility model comprises blower fan 8, be connected to the air main 7 of blower fan 8, three branch wind pipes 5,15,25 that are connected to air main by an air distributor 6, some by 2 discharge pipes 1 that are connected to each branch wind pipe that are flexible coupling, on the tube wall of discharge pipe 1, have some exhaust vents 16, (referring to Fig. 2) can be made of the pipeline section serial connection of the different percent openings of plurality of sections.Offer air-flow access port 17 outside on the pipeline section between air main 7 and blower fan 8, the air inlet of blower fan 8 is connected to a backwind tube 14, and the inlet scoop 13 of backwind tube is arranged on the place, top position on wind webmaster road.18 for being connected on the air stream outlet that communicates with atmosphere on the backwind tube among the figure, when carrying out ventilating, can open the air-flow that this air stream outlet will act on behind the grain heap and put into atmosphere.When fumigating operation, close this air stream outlet and close to form recirculation fumigation.Dotted line is a grain heap outline line among the figure.Haircut is the air flow direction signal.
