Description
Technical Field
The utility model belongs to the technical field of the grain storage and specifically relates to a circulation storage grain system is synthesized to double fan.
Background
Grain is taken as an important strategic reserve material of the country, and is paid more and more attention by storage management departments at all levels, so that granary equipment is more and more applied in the construction of granaries for more than ten years. The current grain storage warehouse is provided with systems such as internal circulation temperature control, circulation fumigation, electronic temperature measurement and the like, most of single equipment is supplied by different manufacturers, each system is an independent system, the equipment deployment is various, and centralized control cannot be realized. The systems can not be effectively matched, the working efficiency is low, and the grain storage effect is poor.
In order to solve the problem, patent No. 2016204857935 discloses an internal circulation temperature control, conditioning and fumigation three-in-one system. However, the system adopts the same fan, and the airflow only has a downward operation mode, so that the system has two problems:
firstly, according to the requirements of technical regulations, the technological parameters of the circulation temperature control process and the circulation fumigation process are different, and one fan cannot meet the requirements of the technical regulations.
For circulation temperature control, the fan power is required to be more than or equal to 1.5kW, the wind pressure is required to be more than or equal to 1000Pa, and the wind quantity is required to be more than or equal to 1000m3The wind speed of the air outlet is controlled below 25 m/s;
for circulation fumigation: the power of the fan is required to be less than or equal to 1kW, the wind pressure is required to be less than or equal to 1000Pa, and the windThe amount is less than or equal to 1000m3The wind speed in the circulation pipeline is preferably controlled to be below 15m/s, and the edge linearity of the fan blade is less than 40 m/s.
Secondly, the circulation temperature control and the circulation fumigation are different in proper airflow direction, and a descending airflow direction is suitable for circulation temperature control, namely, the airflow in the granary flows from top to bottom; for circulation fumigation, an upward airflow direction is suitable, namely, the airflow in the granary flows from bottom to top. The air flow direction in the above patent is from top to bottom only and obviously does not meet the requirement.
In the circulation fumigation process, if the airflow adopts a descending mode, the problems in the following aspects mainly exist:
first, Phosphine (PH)3) The lower limit of the spontaneous combustion explosion concentration is 26mg/L, if descending airflow is adopted, air is discharged from the bottom of the bin, air is introduced into the top of the bin, and due to the blockage of grains, the pressure of the top of the bin is increased, so that the energy of the top of the bin is accumulated, and the bin is easy to explode.
Secondly, the air tightness of the bin top is poor, and if descending airflow is adopted, the medicament is wasted.
Thirdly, the grain loading line is high (the squat silo is generally higher than 20 meters), if the manual silo top grain surface application is adopted, the operation of ascending a height is achieved, and the grain loading line is unsafe in the fumigation medicament environment.
Fourth, special fumigation, such as circulation fumigation under the film, if downward airflow is used, the film of grain will bulge, and the fumigation operation cannot be realized.
