Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the temperature uniformity of the ultra-high grain pile has not been effectively solved at present. The whole warehouse is cooled by using fresh air, and ventilators are installed around the roof of the warehouse, and the wind can be ventilated from multiple outlets. Effectively improve the uniformity of the temperature of the grain pile, but the disadvantage of fresh air operation is that part of the cooling capacity will be wasted into the environment with the exhaust air, and the energy consumption is high. The purpose is to provide a cold recovery equipment for ultra-high grain storage , to solve the above problem

Embodiment 1

[0031] Such as figure 1 As shown, a kind of cold recovery equipment for ultra-high grain depots includes a housing 12, and the housing 12 is provided with a return air chamber 13, an air outlet chamber 14, an air supply chamber 15 and a condensation air chamber 16, and the return air chamber 13 is An evaporating fan 1 is provided, a heat exchanger 2 is provided between the return air chamber 13 and the air outlet chamber 14, a refrigeration system and a condensing fan 8 are provided in the condensing air chamber 16, and a condenser is provided between the refrigerating system and the condensing fan 8 7. An air chamber on-off mechanism 11 is set between the air outlet chamber 14 and the air supply chamber 15. The return air chamber 13 communicates with the air supply chamber 15 and the surface space of the grain pile, while the condensation air chamber 16 communicates with the external environment.

[0032] The air chamber on-off mechanism 11 has two working states. In the firs...

Embodiment 2

[0035] This embodiment is based on Embodiment 1 to further illustrate the present invention.

[0036] Such as figure 1 , image 3 As shown, in the temperature control mode, the air chamber on-off mechanism 11 disconnects the air outlet chamber 14 from the condensation air chamber 16, and the air outlet chamber 14 communicates with the air supply chamber 15; the high-temperature and high-pressure gaseous refrigerant is discharged by the compressor 10 Finally, it enters port D of the four-way reversing valve 9 and is connected to port C. Due to the action of the one-way valve 6, the refrigerant flows to the condenser 7. In the condenser 7, it exchanges heat with the condensed air and continues to flow to The throttling element 3 flows to the heat exchanger 2. In the heat exchanger 2, it exchanges heat with the evaporative return air A1, the temperature of the evaporative return air decreases, and becomes the low-temperature evaporative outlet air A2, which is sent in by the eva...

Embodiment 3

[0039] This embodiment is based on Embodiment 1 to further illustrate the present invention.

[0040] Such as figure 2 , Figure 4 As shown, in the cold recovery mode, the air chamber on-off mechanism 11 connects the air outlet chamber 14 with the condensation air chamber 16, the outlet air chamber 14 is disconnected from the air supply chamber 15, and the cold recovery air of the return air chamber 13 passes through The heat exchanger 2, after being heated by the heat exchanger 2, passes through the air outlet chamber 14, reaches the condensation air chamber 16, and is discharged into the external environment;

[0041] After the high-temperature and high-pressure gaseous refrigerant is discharged by the compressor 10, it enters the D port of the four-way reversing valve 9 and is connected to the E port. The recovered inlet air C1 is heated into cold recovered outlet air C2, and discharged into the external environment, while the refrigerant is cooled into a high-pressure l...

Abstract

The invention discloses cold recycling equipment for a ultrahigh grain depot and a grain storage system provided with the equipment. The cold recycling equipment comprises a shell, wherein an air return cavity, an air outlet cavity, an air feeding cavity and a condensation air cavity are formed in the shell; an evaporation blower is arranged in the air return cavity; a heat exchanger is arranged between the air return cavity and the air outlet cavity; a refrigeration system and a condensation blower are arranged in the condensation air cavity; a condenser is arranged between the refrigerationsystem and the condensation blower; an air cavity connection/disconnection mechanism is arranged between the air outlet cavity and the air feeding cavity; the air return cavity communicates with the air feeding cavity and a surface layer space of a grain stack; and the condensation air cavity communicates with an external environment. According to the cold recycling equipment for the ultrahigh grain depot disclosed by the invention, temperature control can be realized, and cooling capacity recovery also can be carried out, so that energy consumption of an all fresh air whole warehouse during cooling is effectively reduced.

Description

technical field [0001] The invention relates to the field of grain storage, in particular to a cold recovery device for an ultra-high grain depot and a grain storage system equipped with the device. Background technique [0002] The ultra-high grain depot represented by the shallow round warehouse is one of the important grain storage warehouse types. Its advantages are high degree of mechanization and small footprint. It is widely used in large-scale port grain depots and transitional grain depots. Used as short-term storage for turnover. Due to its small footprint, in the era when the land value is getting higher and higher, this feature has attracted many customers when building new warehouses. In addition, the labor cost is high now, and mechanization is getting more and more attention. Therefore, the shallow round warehouse has become a lot of The preferred warehouse type for new grain depots. In the process of use, the shortcoming that the shallow round warehouse is ...
