Embodiment 1

[0021] Such as figure 1 , image 3 As shown, an environment-friendly grain drying and deworming system includes a support 1 and a treatment chamber 2 fixed on the support 1. The upper and lower ends of the treatment chamber 2 are respectively provided with a grain inlet pipe 3 and a grain outlet pipe 11. The inlet of the grain inlet pipe 3 is provided with a grain inlet valve 3-1 that can seal the grain inlet pipe 3, and the outlet of the grain outlet pipe 11 is provided with a grain outlet cover 11-1 that can cover the grain outlet pipe 11. 1. Between the grain inlet pipe 3 and the grain outlet pipe 11, there is a grain circulation pipe 7 and a grain lifting pump 7-1 which circulates the grain, and the grain circulation pipe 7 is also provided with a The aspirating pump 9 that gas is extracted, the filter screen 10 that prevents grain from passing is set between the aspirating pump 9 and the grain circulation pipe 7; The air distribution interlayer 2-1 is connected with a d...

Embodiment 2

[0030] Such as figure 2 As shown, further optimization on the basis of Example 1, in order to realize grain diversion, ensure sufficient contact between grain and dry nitrogen and be fully irradiated by ultraviolet lamps, and further improve drying and deworming efficiency, the grain feeding pipe 3 is provided below The first flow divider 4, the second flow divider 5 is provided at the top opening of the treatment chamber 2, the first flow divider 4 and the second flow divider 5 are both rotary structures, the first flow divider 4 and the second flow divider The upper ends of the 5 are in a tapered structure with the tip pointing upwards, and the central axes of the first flow divider 4 and the second flow divider 5 coincide.

[0031] In this embodiment, the setting of the first flow divider 4 and the second flow divider 5 prevents the grain entering the processing chamber 2 from falling concentratedly, thereby ensuring sufficient contact between the grain and the dry nitroge...

Embodiment 3

[0035] Such as Figure 4 As shown, further optimization on the basis of embodiment 1 or embodiment 2, in order to avoid drying and grain entering the grain circulation pipe 7 after the grain is dried, the entrance of the grain circulation pipe 7 is also provided with a grain retaining plate 12, The grain retaining plate 12 is slidingly connected to the inner wall of the grain outlet pipe 11, and the vertical chute 13 matching the grain retaining plate 12 is arranged on the inner wall of the grain outlet pipe 11, and the entrance of the grain circulation pipe 7 is located at In the middle position of the chute 13, the grain retaining plate 12 and the grain output cover 11-1 are connected through a connecting rod 16, and the connecting rod 16 is rotationally connected with the grain retaining plate 12 and the grain output cover 11-1. The side of the grain outlet cover 11 - 1 away from the connecting rod 16 is rotationally connected with the grain outlet pipe 11 .

Abstract

The invention discloses an environment-friendly grain drying and disinsection system. The system comprises a support and a processing chamber fixed to the support, the upper end and the lower end of the processing chamber are provided with a grain feeding pipe and a grain discharging pipe respectively, an inlet of the grain feeding pipe is provided with a grain feeding valve capable of sealing thegrain feeding pipe, and a grain discharging cover capable of covering the grain discharging pipe is arranged at an outlet of the grain discharging pipe; a grain circulating pipe and a grain lifting pump are arranged between the grain feeding pipe and the grain discharging pipe, and the grain circulating pipe and the grain lifting pump are used for circularly processing grains; an air suction pumpfor pumping air in the grain circulating pipe is further arranged on the grain circulating pipe, and a filter screen for preventing the grains from passing through is arranged between the air suctionpump and the grain circulating pipe; a bottom plate of the processing chamber is provided with a gas distribution interlayer for distributing air in the processing chamber; the air distribution interlayer is connected with a dry nitrogen pipe, an electric heating wire is arranged in the dry nitrogen pipe, and a plurality of ultraviolet lamps are uniformly distributed on the side wall of the processing chamber. The system is small in occupied space; no toxic substance is used, so that the damage to the environment is small.

Description

technical field [0001] The invention belongs to the field of grain storage equipment, and in particular relates to an environment-friendly grain drying and deworming system. Background technique [0002] In the long-term grain storage process in China, the pest control process is separated from the drying process, which has the characteristics of a large space occupied by the device and a complex grain transportation structure. Moreover, in the pest control, the circular fumigation device is used to kill the insects by injecting poisonous gas into the grain. After the insecticide is completed, the gas is discharged into the sky, which greatly pollutes the environment; Incidents are likely to affect the health of operators; in addition, if poisonous gas is used for insecticide treatment, there will be more or less trace residues on the food, which will affect food safety. Contents of the invention [0003] The invention provides an environment-friendly grain drying and dew...
