DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0030] As Figures 1 to 7As shown in the embodiment of the present invention, a grain storage heat exchange tube assembly includes multiple heat exchange tubes 1; a first magnetic block 11 is fixedly connected to the inner wall of both sides of the groove in the middle of each heat exchange tube 1; a sliding plate 12 is slidably connected to the inner wall of each heat exchange tube 1, and multiple air holes are opened on the inner wall of each heat exchange tube 1 near the sliding plate 12; a second magnetic block 13 is fixedly connected to both sides of each sliding plate 12, and the second magnetic block 13 and the first magnetic block 11 are arranged opposite to each other; a flow divider 14 is provided on the outside of the sliding plate 12; the sliding plate... A connecting adjustment assembly is provided on the 12, which is used to connect the air vents of the heat exchange tube 1 to the flow divider plate 14 through the sliding plate 12, and can simultaneously adjust the angle of the flow divider plate 14; a plurality of first-order guide pipes 15 are uniformly fixed to the end of the flow divider plate 14 away from the sliding plate 12, and a plurality of first-order through holes are opened on the first-order guide pipes 15; when using the heat exchange tube assembly to exchange heat with the grain stored in the grain silo, according to the temperature change in the grain silo, if the temperature in the grain silo is low, which is common in cold weather, then the multiple heat exchange tubes The first heat exchanger tube 1 is directly connected to a heating device at one end, and the other end of the last heat exchanger tube 1 is sealed. The heating device generates hot air that blows into the interior of the heat exchanger tube 1. The hot air passes through one of the multiple air holes and enters the interior of the distribution plate 14 through the sliding plate 12. At this time, a second magnetic block 13 on the sliding plate 12 is magnetically attracted to a first magnetic block 11 on one side of the heat exchanger tube 1. The connecting adjustment component adjusts the multiple first guide tubes 15 on the distribution plate 14 to be placed horizontally. 5. Insert the tube into the grain pile. Hot air is discharged from multiple No. 1 through holes of the No. 1 guide pipe 15, which heats the grain silo. When the temperature inside the grain silo exceeds the set value, the grain silo is opened to release heat, so that the grain silo is kept within the set temperature range. If the temperature inside the grain silo is high, which is common in hot weather, the heating equipment can be replaced with a cooling equipment. When the cooling equipment is working, cold air is blown into the heat exchange pipe 1 and guided to the grain silo for heat dissipation. At the beginning of heat dissipation, the grain silo can be opened for rapid ventilation until the grain silo is kept within the set temperature range.

[0045] When the heat exchange in the granary is carried out, according to the size of the stored grain pile, the first extension pipe 3 is adjusted to slide on the first guide pipe 15, so that the first extension pipe 3 cooperates with the first guide pipe 15 to uniformly heat the grain at this position, expands the heat exchange area, and the hot air or cold air entering the first guide pipe 15 can be discharged through the first through hole on the first guide pipe 15 and the first extension pipe 3, thereby achieving uniform heat exchange of different sizes of grain piles;

[0046] When the part of the granary is seriously affected by moisture due to the geological influence, the connecting barrel 4 connected by the flow control assembly is fixed on one side of the middle part of the distribution plate 14, the first corrugated pipe 41 inside the connecting barrel 4 is partially pulled out, the second guide pipe 42 is inserted into the area where the grain is seriously affected by moisture in cooperation with the second extension pipe 43, the flow control assembly is in an open state at this time, then the heating device supplies hot air in the first guide pipe 15 and the first corrugated pipe 41, part of the hot air is used to dry the local area where the moisture is serious through the second guide pipe 42 and the second extension pipe 43, which plays a role in strengthening the drying of the local area; when the local area is strengthened and dried, the threaded barrel 51 is screwed in the inside of the fixed barrel 5 by the connecting barrel 4, so that the end of the threaded barrel 51 away from the first corrugated pipe 41 cancels the blockage of the internal passage of the fixed barrel 5, the hot air passes through the flow-through groove on the side of the fixed barrel 5 and the threaded barrel 51 from the inside of the distribution plate 14, and the hot air enters the first corrugated pipe 41 and is discharged at the second guide pipe 42 and the second extension pipe 43, when the use of the second guide pipe 42 and the second extension pipe 43 is stopped, the second extension pipe 43 is slidably stored on the second guide pipe 42, the second guide pipe 42 is inserted into the inside of the connecting barrel 4 and stored, the connecting barrel 4 is reversely rotated, the threaded barrel 51 is reversely screwed by the connecting barrel 4, the end of the threaded barrel 51 away from the first corrugated pipe 41 is blocked at the internal passage of the fixed barrel 5, which plays a role in controlling and blocking the air inlet passage of the first corrugated pipe 41;

[0047] When the heat-exchanged gas is discharged, the two ends of the channel composed of multiple heat-exchange pipes 1 are located outside the granary, and the middle part of the channel is located inside the granary. The partition plate 6 separates the internal channel of the heat-exchange pipe 1 into two parts, one half of which is the air inlet chamber and the other half is the air outlet chamber. When heating, the air inlet chamber of the heat-exchange pipe 1 at one end of the channel is connected to the heating device, the air inlet chamber of the heat-exchange pipe 1 at the other end of the channel is sealed with a sealing plug 63, the air outlet chamber at the heating device is sealed with another sealing plug 63, and the air outlet chamber at the other end is in an open state. Hot gas enters the internal part of multiple first guide pipes 15 and first extension pipes 3, and the hot gas heats the outer walls of the first return cylinder 61 and the second return cylinder 62. The first return cylinder 61 and the second return cylinder 62 are inserted into the grain pile to exchange heat with the grain. The heat-exchanged gas in the first return cylinder 61 and the second return cylinder 62 is discharged into the air outlet chamber by the ventilation assembly, and is discharged from the air outlet chamber at the end farthest from the heating device. At the same time, when cooling the granary, the heating device is replaced with a refrigeration device to achieve the effect of arranging the return flow channel for heat exchange in the granary. When the first return cylinder 61 and the second return cylinder 62 are heat-exchanged with the granary, the gas is discharged from the guide ring 7 into the internal part of the first return pipe 71, and then the gas is discharged into the air outlet chamber by the second return pipe 72 cooperating with the guide block 73. Finally, the heat-exchanged gas is discharged from the air outlet chamber, which plays a role in returning and sending the heat-exchanged gas. At the same time, when the multiple shunt plates 14 adjust the position, the soft second return pipe 72 can cooperate with the hard first return pipe 71 to ensure that the pipeline is not severely bent, thereby maintaining the effect of gas delivery.

[0048] When multiple heat-exchange pipes 1 form a heat-exchange channel, the second corrugated pipe 8 and the third corrugated pipe 81 are used as connections between two heat-exchange pipes 1. The heat-exchange channel connected by the second corrugated pipe 8 and the third corrugated pipe 81 can be bent according to the height position required by different areas, thereby improving the heat exchange effect in the granary. When assembling the heat-exchange channel, the two heat-exchange pipes 1 are connected by the second corrugated pipe 8 and the third corrugated pipe 81. The second corrugated pipe 8 connects the air inlet chambers of the two heat-exchange pipes 1, and the third corrugated pipe 81 connects the air outlet chambers of the two heat-exchange pipes 1. The second corrugated pipe 8 and the third corrugated pipe 81 are used to connect multiple heat-exchange pipes 1, thereby facilitating adaptive assembly in different granaries.

[0049] When part of the area in the granary is placed with idle objects, multiple 15 can be vertically erected in the empty position by sliding the 12. When there is no need to empty the position and need to stop the heat exchange here, the normally open electromagnetic valve 9 in the sliding plate 12 can be controlled to close, so that multiple first guide pipes 15 do not exchange heat, thereby improving the control effect of heat exchange in part of the area.
