specific Embodiment approach 1

[0019] Specific implementation mode one: combine figure 1 Describe this embodiment, the new grain storage four-in-one technology of this embodiment and two-way ventilation, circulation, air conditioning, ozone grain storage system press-in type to reduce grain temperature, use this mode of ventilation, first need to open the granary window 7 and the ventilation cage cover Plate 8, close the airtight valve 11, start the two-way mixed flow fan 4, realize press-in ventilation, the external air passes through the two-way mixed flow fan 4, passes through the granary ventilation cage 3, passes through the grain pile upwards, and finally discharges into the atmosphere through the granary window 7 , this kind of ventilation mode, the gas touches the bottom of the grain pile first, the grain at the bottom layer cools down first, and the grain at the upper layer cools down and gets water last. high.

specific Embodiment approach 2

[0020] Specific implementation mode two: combination figure 2 Illustrate this embodiment, this embodiment adopts the suction-type ventilation mode for lowering the grain temperature, first open the granary window 7 and the ventilation cage cover 8, close the airtight valve 11, start the two-way mixed-flow fan 4 suction-type ventilation, the outside atmosphere passes through the window, Pass through the grain pile, pass through the ventilation cage 3 of the granary, pass through the two-way mixed flow fan 4, and finally discharge out of the warehouse through the second vent 6; in this ventilation mode, the gas first touches the upper layer of the grain pile, and the grain on the upper layer is first cooled and dehydrated. The grain at the bottom finally cools down and rains. After long-term ventilation, the grain moisture in the upper layer is low, and the grain moisture in the bottom is high.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination image 3 To illustrate this embodiment, the press-in recyclable part of the "tail gas" ventilation mode for lowering the grain temperature is adopted. Using this mode for ventilation, the granary window 7 and the ventilation cage cover 8 are opened, the airtight valve 11 is closed, and the two-way mixed flow fan 4 is started to press in The external air passes through the two-way mixed-flow fan 4, passes through the granary ventilation cage 3, and passes through the grain pile upwards. Part of the gas is discharged into the atmosphere through the granary window 7, and part of the discharged air enters the negative side of the two-way mixed-flow fan through the ventilation circulation pipe 2. The compressor end (that is, the ventilation reserved opening 9) re-enters the grain pile. This ventilation mode can slightly increase the temperature and humidity of the ventilation air, reducing the moisture loss in the ventilation pr...

Abstract

The invention discloses a novel grain storage four-in-one technology and two-way ventilation, circulation, air conditioning and ozone grain storage system, and belongs to the technical field of mechanical ventilation for grain. The system aims at solving the problem that in the existing grain storage process, grain in a barn ages and mildews due to the low circulation ventilation technology level. The system comprises a barn wall, a ventilation circulation pipe, a grain ventilation cage and a two-way mixed flow fan, wherein the ventilation circulation pipe is installed on the inner side wall of the barn wall, the barn ventilation cage is installed on the bottom surface of a barn, the two-way mixed flow fan is installed at the lower end of the ventilation circulation pipe and arranged in the grain ventilation cage, and a first ventilation opening and a second ventilation opening are formed in the upper end and the lower end of the barn wall respectively. The system is compact in structure, control is convenient, ventilation circulation can be effectively achieved to prevent grain from ageing and mildewing, and the effects of killing microorganisms, grain storage pests and worm eggs and purifying grain piles can be achieved.

Description

technical field [0001] The invention relates to a granary ventilation and circulation system, which belongs to the technical field of grain mechanical ventilation. Background technique [0002] After the grain is harvested, it generally needs to be stored for a certain period of time before being put on the market. Therefore, safe storage of grain is an important task in the grain industry. The basic purpose is to delay the aging and deterioration of grain during the grain storage process. [0003] The existing storage methods mainly use two types of warehouses: room-type warehouses and vertical silos. After grain is stored, in order to keep it low temperature and dry, it is usually necessary to use certain ventilation methods to reduce grain temperature and moisture. my country Traditional low-temperature grain storage methods include natural ventilation low temperature, mechanical ventilation low temperature and mechanical refrigeration low temperature. With the development...
