Dehumidification device for granary security and protection

Abstract

The invention belongs to the technical field of granary security and protection, and particularly relates to a dehumidification device for granary security and protection. The following scheme is provided currently in order to solve the problems that an existing dehumidification device can only dehumidify the surfaces of grains and is limited in dehumidification depth, the dehumidification devicecomprises a hanging rail erected at the top end of a granary and a hanging box which is internally provided with a cavity and is integrally of a cuboid structure; a hoop matched with the hanging railis fixed to the top end of the hanging box, two rectangular pipes are embedded into the bottom end of the hanging box, extension plates are slidably connected to the two ends of the two rectangular pipes, and driving boxes of cuboid structures are embedded into the opposite ends of the two extension plates; and sliding bearings which are coaxially distributed are embedded into the top ends and thebottom ends of the driving boxes correspondingly, the same jacking pipe is slidably connected between two sliding bearings, cutting shoulders are formed in the outer walls of the jacking pipes, and tooth surfaces are arranged on the surfaces of the cutting shoulders. The dehumidification device is simple in structure and good in dehumidification effect, can dehumidify places with different depths, and can turn over in time.

Description

technical field [0001] The invention relates to the technical field of granary security, in particular to a dehumidification device for granary security. Background technique [0002] Grain reserves are to ensure the food consumption needs of the non-agricultural population; the existence of high-moisture grains puts great pressure on the food quality and safety of reserve enterprises. Due to its high moisture content, high-moisture grains provide a better environment for the reproduction of insect pests and grain-borne bacteria. The activity is accelerated, and the biological activity and microbial activity cannot be effectively inhibited, which makes the food easy to heat up. If the heat dissipation is not smooth, it is easy to cause the food to age and turn yellow, and then mold and deteriorate. In order to ensure the safe storage of grain, it is necessary to ensure that the grain is below the safe moisture level, and reduce the air humidity in the grain storage silo, so...

Problems solved by technology

At present, there are various air dehumidification devices on the market, but the dehumidification effect is not ideal.

[0003] After retrieval, the Chinese patent number is CN201821678285.4, which discloses a dehumidification device for a grain storage silo, including a dehumidification pipe, a first compressor, a second compressor, a third compressor, a first evaporator, a second evaporator, a third The evaporator, the first condenser, the second condenser and the third condenser, the air outlet of the dehumidification pipe is provided with an induced draft fan, the middle part of the dehumidification pipe is provided with the dehumidification heat exchanger, and the bottom of the dehumidification heat exchanger is provided with a water storage tank, The first evaporator is provided upstream of the air flow of the dehumidification heat exchanger; however, this device can only dehumidify the surface of the grain, and the dehumidification depth is limited, so it is not suitable for the use of large storage-shaped granaries
