Abstract
A kind of silo air circulation device, belongs to granary air conditioning equipment technical field, for gas circulation temperature lowering in silo.Its technical scheme is: the utility model utilizes existing two circulating pipes on silo, small-sized axial flow fan is installed to the inside of circulating pipe, and circulating pipe lower end is connected to dish valve with irony tube connector, dish valve is connected with the ventilating opening of circulating pipe below, make in storehouse and storehouse Outer Tube forms a closed entirety by above connection, make the gas can circular flow in circulating pipe and silo.The utility model utilizes small-sized axial flow fan circulation grain to pile inner low-temperature receiver, and grain heap internal difference in temperature is carried out to balance, has changed grain storage environment, prevents growing of insect and microorganism, guarantees that stored grain safety aestivates, the effect of simultaneously reach energy-saving and cost-reducing, increasing economic efficiency.The utility model is simple in structure, easy to use, and insect-pest is respond well, can save the energy simultaneously, reduces grain storage cost, can in grain depot, apply.
Description
Technical field
The utility model relates to Air Flow equipment in a kind of grain depot silo, belongs to granary air conditioning equipment technical field.
Background technology
Silo is the critical facility of grain depot storage grain, and grain adopts the mode of piling up to store in silo.Winter, silo will ventilate with the external world, reduced temperature in storehouse, and to store better grain under low-temperature condition, after ventilating in the winter time, grain stack temperature reduces, and grain is piled inner grain in low-temperature condition.Entering into the impact that raise by outside air temperature after summer, the storehouse temperature of silo and top layer grain temperature can raise with the rising of ambient temperature, and at this moment the temperature of grain heap surface and grain heap internal layer has produced the comparatively significant temperature difference.The rising of grain heap surface temperature contributes to growing of insect and microorganism, must reduce the temperature of grain heap surface, general method is to adopt the equipment such as ventilation, air-conditioning to lower the temperature of grain heap surface, and uses air-conditioning equipment energy consumption high, has increased the cost storing grain.Due to grain heap inside lower the temperature in the winter time after in low-temperature condition, these low-temperature grains just become low-temperature receiver that can balance grain heap internal-external temperature difference, but are not effectively utilized so far.Therefore be necessary design air flow-through device, make full use of the grain of grain heap inner cryogenic state, reach the object of reducing temperature for preventing insect pest.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of silo air circulation device, the grain that this circulating device can make grain in storehouse pile inner low-temperature condition absorbs the heat of top layer grain, balance grain heap internal difference in temperature, simultaneously with storehouse in high temperature air carry out heat exchange, change grain storage environment, reach the object that prevents insect and microbial growth.The technical scheme solving the problems of the technologies described above is:
A kind of silo air circulation device, it comprises circulating pipe, axial flow blower, damping bellows, the two ends of circulating pipe are connected by tube connector with the upper and lower of silo respectively, axial flow blower is arranged in the bottom tube chamber of circulating pipe, on the circulating pipe of axial flow blower below, connects damping bellows.
Above-mentioned silo air circulation device, the junction of described circulating pipe and silo bottom is provided with butterfly valve, and butterfly valve is connected with ventilating opening.Above-mentioned silo air circulation device, described circulating pipe, axial flow blower, damping bellows, butterfly valve are two covers, are arranged on respectively on the two side that silo is relative, circulating pipe and connecting pipe are all wrapped up with insulation material rubber-plastic sponge.
The beneficial effects of the utility model are:
The utility model utilizes existing two circulating pipes on silo, small-sized axial flow fan is installed to the inside of circulating pipe, and circulating pipe lower end is connected to dish valve with irony tube connector, dish valve is connected with the ventilating opening of circulating pipe below, make in storehouse and storehouse Outer Tube forms a closed entirety by above connection, make the gas can circular flow in circulating pipe and silo.The utility model utilizes small-sized axial flow fan circulation grain to pile inner low-temperature receiver, and grain heap internal difference in temperature is carried out to balance, has changed grain storage environment, prevents growing of insect and microorganism, guarantees that stored grain safety aestivates, the effect of simultaneously reach energy-saving and cost-reducing, increasing economic efficiency.The utility model is simple in structure, easy to use, and insect-pest is respond well, can save the energy simultaneously, reduces grain storage cost, can in grain depot, apply.
