[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7As shown, a heat exchange tube assembly for granary storage according to an embodiment of the present invention comprises a plurality of heat exchange tubes 1; a first magnetic block 11 is fixedly connected to the inner walls on both sides of the middle groove of the heat exchange tube 1; a sliding plate 12 is slidably connected to the inner wall of the heat exchange tube 1, and a plurality of air holes are opened on the inner wall of the heat exchange tube 1 near the sliding plate 12; a second magnetic block 13 is fixedly connected to both sides of the sliding plate 12, and the second magnetic block 13 and the first magnetic block 11 are arranged oppositely; a diverter plate 14 is arranged outside the sliding plate 12; the sliding plate A connection adjustment component is provided on 12, and the connection adjustment component is used to connect the air hole of the heat exchange tube 1 with the diverter plate 14 through the sliding plate 12, and at the same time can adjust the angle of the diverter plate 14; the diverter plate 14 is evenly fixed with a plurality of No. 1 guide tubes 15 at one end away from the sliding plate 12, and the No. 1 guide tube 15 is provided with a plurality of No. 1 through holes; when the heat exchange tube assembly is used to heat the grain stored in the granary, according to the temperature change in the granary, if the temperature in the granary is low, which is common in cold weather, the plurality of heat exchange tubes 1 are directly connected, one end of the first heat exchange tube 1 is externally connected to the heating equipment, and the other end of the last heat exchange tube 1 is blocked. The heating equipment generates hot air that is blown into the interior of the heat exchange tube 1, and the hot air passes through one of the multiple air holes through the sliding plate 12 and enters the interior of the diverter plate 14. At this time, a No. 2 magnetic block 13 on the sliding plate 12 is magnetically attracted to the No. 1 magnetic block 11 on one side of the heat exchange tube 1, and the connection adjustment component adjusts the multiple No. 1 guide tubes 15 on the diverter plate 14 to be placed horizontally, and the multiple No. 1 guide tubes 1 5 is inserted into the grain pile, and the hot air is discharged from the multiple No. 1 through holes of the No. 1 guide pipe 15 to increase the temperature in the granary. When the temperature in the granary exceeds the set value, the granary is opened to release heat, so that the temperature in the granary is maintained within the set temperature range; if the temperature in the granary is high, which is common in hot weather, the heating equipment can be replaced with a refrigeration equipment. The refrigeration equipment blows cold air into the interior of the heat exchange pipe 1 and guides it to the granary for heat dissipation. When the heat dissipation starts, the granary can be opened for rapid ventilation until the temperature in the granary is maintained within the set temperature range; When faced with a situation where some areas inside the granary are short of food and do not need heat exchange, the sliding plate 12 in the food-shortage area is manually adjusted to slide toward the top of the heat exchange tube 1. At this time, another No. 2 magnetic block 13 on the sliding plate 12 is magnetically attracted to the No. 1 magnetic block 11 on the top of the heat exchange tube 1, limiting the position of the sliding plate 12, and multiple No. 1 guide tubes 15 are also erected on the top of the heat exchange tube 1. The air holes of the heat exchange tube 1 are misaligned and blocked because the sliding plate 12 slides to the top of the heat exchange tube 1. The inside of the heat exchange tube 1 here can only be used for air intake from one end and air outlet from the other end. If it is necessary to use multiple No. 1 guide tubes 15 here, the sliding plate 12 can be slid in the opposite direction and reset, which plays a role in adjusting and controlling the closing state of the sliding plate 12 in the food-shortage area; When different grains are placed in different areas, with one type of grain occupying a larger area and the other type of grain occupying a smaller area, the sliding plate 12 can be manually adjusted to slide left or right, and multiple No. 1 flow guide pipes 15 can also slide accordingly. One of the multiple air holes on the heat exchange tube 1 can be connected to the sliding plate 12, so that the distance between the No. 1 flow guide pipes 15 on the multiple heat exchange tubes 1 increases or decreases, thereby facilitating heat exchange of grains in different areas, improving the heat exchange effect of the heat exchange tube assembly on grains, and being able to adaptably adjust the position of the heat exchange tube assembly according to different situations.

[0024] The connection adjustment assembly includes a connection block 2, a limit plate 21 and an elastic member 22; the connection block 2 is fixedly connected to the outer wall of the sliding plate 12, and the diverter plate 14 is inserted into the interior of the connection block 2; the limit plate 21 is slidably connected to the inner wall of the connection block 2, and one end of the limit plate 21 is arranged in an arc shape; the elastic member 22 is fixedly connected between the inner wall of the connection block 2 and the limit plate 21; a plurality of limit grooves 23 are provided on the outer wall of the protruding portion of the diverter plate 14, and the limit grooves 23 correspond to the arc-shaped end of the limit plate 21; when the partially deformed part in the granary is adjusted, the limit plate 21 is adjusted to the inner wall of the connection block 2 and the limit plate 21; the limit grooves 23 are arranged ... When heat is exchanged in a deformed area, in order to improve the heat exchange effect on the grain stored in the granary, the diverter plate 14 is rotated according to the size of the storage space, and the limit groove 23 opened on the diverter plate 14 squeezes the limit plate 21 to slide up, and the limit plate 21 squeezes and contracts the elastic member 22. Then, another limit groove 23 on the diverter plate 14 corresponds to the limit plate 21, and the elastic force of the elastic member 22 is reset to squeeze the limit plate 21 into another limit groove 23, thereby realizing the angle adjustment of multiple No. 1 guide pipes 15 on the diverter plate 14, which is suitable for heat exchange in deformed areas.

[0025] like Figures 1 to 4 As shown, the outer wall of the No. 1 guide pipe 15 is slidably connected to the No. 1 extension pipe 3; the No. 1 extension pipe 3 is provided with a plurality of No. 1 through holes corresponding to the No. 1 guide pipe 15; when exchanging heat in the granary, according to the size of the stored grain pile, the No. 1 extension pipe 3 is adjusted to slide on the No. 1 guide pipe 15, so that the No. 1 extension pipe 3 cooperates with the No. 1 guide pipe 15 to evenly exchange heat with the grain here, expand the heat exchange area, and the hot air or cold air entering the No. 1 guide pipe 15 can be discharged along the No. 1 through holes on the No. 1 guide pipe 15 and the No. 1 extension pipe 3, thereby achieving uniform heat exchange for grain piles of different sizes.

[0026] like Figures 1 to 5 , Figure 7As shown, a connecting tube 4 is provided on the outside of the diverter plate 14; a No. 1 bellows 41 is fixedly connected to the inside of the connecting tube 4, and the end of the No. 1 bellows 41 close to the diverter plate 14 is fixedly connected to the inner wall of the connecting tube 4, and the end of the No. 1 bellows 41 away from the diverter plate 14 is slidably connected to the inner wall of the connecting tube 4; a No. 2 guide tube 42 is fixedly connected to the end of the No. 1 bellows 41 away from the diverter plate 14; a No. 2 extension tube 43 is slidably connected to the outer wall of the No. 2 guide tube 42, and a plurality of No. 2 through holes are provided on the outer walls of the No. 2 guide tube 42 and the No. 2 extension tube 43; a flow control component is provided between the diverter plate 14 and the connecting tube 4, and the flow control component is used to Control the connectivity between the diverter plate 14 and the connecting tube 4; when some areas in the granary are severely damp due to geological influences, the connecting tube 4 connected to the flow control component is fixed on the middle side of the diverter plate 14, and the No. 1 bellows 41 inside the connecting tube 4 is partially pulled out, and the No. 2 guide tube 42 cooperates with the No. 2 extension tube 43 to be inserted into the area where the grain is severely damp. The flow control component is in the open state at this time, and then the heating equipment supplies hot air to multiple No. 1 guide tubes 15 and No. 1 bellows 41. Part of the hot air dries the local severely damp areas from the multiple No. 2 through holes on the No. 2 guide tube 42 and the No. 2 extension tube 43, thereby enhancing the drying of the local areas.

[0027] The flow control assembly includes a fixed cylinder 5 and a threaded cylinder 51; the fixed cylinder 5 is fixedly connected to the central outer wall of the side of the diverter plate 14 away from the heat exchange tube 1; the threaded cylinder 51 is fixedly connected to the outer wall of the end of the connecting cylinder 4 away from the first bellows 41, and a flow groove is opened on the side of the threaded cylinder 51, and the threaded cylinder 51 is threadedly connected to the inner wall of the fixed cylinder 5; when the local area is dried intensively, the connecting cylinder 4 is used to drive the threaded cylinder 51 to rotate inside the fixed cylinder 5, so that the end of the threaded cylinder 51 away from the first bellows 41 cancels the blockage of the internal channel of the fixed cylinder 5, and the hot air passes through the fixed cylinder 5 and The hot air enters the circulation groove on the side of the threaded tube 51 and is sent to the No. 1 bellows 41 and the No. 2 guide tube 42 and the No. 2 extension tube 43 for external discharge. When the use of the No. 2 guide tube 42 and the No. 2 extension tube 43 is stopped, the No. 2 extension tube 43 is slid and stored on the No. 2 guide tube 42, and the No. 1 bellows 41 is inserted into the interior of the connecting tube 4 for storage, and the connecting tube 4 is rotated in the reverse direction. The connecting tube 4 drives the threaded tube 51 to rotate in the reverse direction, and the end of the threaded tube 51 away from the No. 1 bellows 41 is pressed against the internal channel of the fixed tube 5 to block it, thereby controlling and blocking the air inlet channel of the No. 1 bellows 41.

[0028] like Figures 1 to 4 , Figure 7As shown, a partition plate 6 is fixedly connected to the interior of the heat exchange tube 1, and the partition plate 6 can divide the interior of the heat exchange tube 1 into an air inlet chamber and an air outlet chamber, and a plurality of air holes are opened in the air inlet chamber; a No. 1 return tube 61 is fixedly connected to the outer wall of the diverter plate 14, and a No. 1 guide tube 15 is located inside the No. 1 return tube 61; a No. 2 return tube 62 is slidably connected to the outer wall of the No. 1 return tube 61, a No. 1 extension tube 3 is located inside the No. 2 return tube 62, and an end of the No. 1 extension tube 3 away from the No. 1 guide tube 15 is fixedly connected to the inner wall of the No. 2 return tube 62; a ventilation component is provided on the heat exchange tube 1, and the ventilation component is used to connect the air outlet chamber with the No. 1 return tube 61; a sealing plug 63 is inserted at one end of the heat exchange tube 1, and the sealing plug 63 is used to block one end of the air inlet chamber; when the gas after heat exchange is discharged, the two ends of the channel composed of multiple heat exchange tubes 1 are respectively located outside the granary, and the middle part of the channel is located inside the granary, and the gas is discharged. The partition 6 divides the internal channel of the heat exchange tube 1 into two parts, one half of the air inlet chamber and the other half of the air outlet chamber. When the temperature rises, the air inlet chamber of the heat exchange tube 1 at one end of the external channel of the heating equipment and the air inlet chamber of the heat exchange tube 1 at the other end of the channel are blocked with a sealing plug 63, and the air outlet chamber at the heating equipment is blocked with another sealing plug 63, while the air outlet chamber at the other end is in an open state, and the hot air passes into the interior of multiple No. 1 guide pipes 15 and No. 1 extension pipes 3 and is discharged. The hot air heats up the outer walls of the No. 1 return tube 61 and the No. 2 return tube 62, and the No. 1 return tube 61 and the No. 2 return tube 62 are inserted into the grain pile to exchange heat with the temperature of the grain. The gas after heat exchange in the No. 1 return tube 61 and the No. 2 return tube 62 is discharged into the air outlet chamber by the ventilation component, and is discharged from the air outlet chamber far away from the heating equipment. At the same time, when cooling the granary, the heating equipment can be replaced with a refrigeration equipment to achieve the effect of heat exchange of the return channel arranged in the granary.

[0029] The ventilation assembly includes a guide ring 7, a No. 1 return pipe 71, a No. 2 return pipe 72 and a guide block 73; the plurality of guide rings 7 are respectively sleeved on the plurality of No. 1 return tubes 61; the No. 1 return pipe 71 is fixedly connected to the two guide rings 7, and the material of the No. 1 return pipe 71 is a hard material; the No. 2 return pipe 72 is fixedly connected to the No. 1 return pipe 71, and the material of the No. 2 return pipe 72 is a soft material; the guide block 73 is fixedly connected to the air outlet cavity of the heat exchange tube 1, and one end of the No. 2 return pipe 72 away from the No. 1 return pipe 71 is fixedly connected to the guide block 73, and the No. 1 return tube 61 can pass through the guide ring 7, The No. 1 return pipe 71, the No. 2 return pipe 72 and the guide block 73 are connected to the air outlet chamber; after the No. 1 return tube 61 and the No. 2 return tube 62 exchange heat with the granary, the gas is discharged from the guide ring 7 into the interior of the No. 1 return pipe 71, and then the No. 2 return pipe 72 cooperates with the guide block 73 to discharge the gas into the air outlet chamber, and finally the air outlet chamber discharges the heat-exchanged gas to the outside, which plays the role of returning and sending the heat-exchanged gas. At the same time, when the positions of multiple diverter plates 14 are adjusted, the No. 2 return pipe 72 made of soft material can cooperate with the No. 1 return pipe 71 made of hard material to ensure that the pipeline is not severely bent, thereby maintaining the effect of gas delivery.

[0031] like Figures 1 to 6 As shown, a solenoid valve 9 is fixedly connected to the interior of the sliding plate 12; the solenoid valve 9 is located at the wind hole of the middle inner wall of the sliding plate 12 close to the heat exchange tube 1; when idle objects are placed in a part of the area in the granary, the multiple No. 1 guide tubes 15 here can be slid up and upright to vacate the position; when there is no need to vacate the position and the heat exchange here needs to be stopped, the solenoid valve 9 in the normally open state in the sliding plate 12 can be controlled to close, so that the multiple No. 1 guide tubes 15 here do not exchange heat, thereby improving the control effect of heat exchange in some areas.

[0032] like Figure 1 and Figure 2As shown, both sides of the heat exchange tube 1 can be fixedly connected with a No. 2 bellows 8 and a No. 3 bellows 81, and a No. 2 bellows 8 and a No. 3 bellows 81 are fixedly connected between the two heat exchange tubes 1. The No. 2 bellows 8 and the No. 3 bellows 81 are used to respectively connect the air inlet cavity and the air outlet cavity between the two heat exchange tubes 1; when the heat exchange channel is assembled, the two heat exchange tubes 1 are connected through the No. 2 bellows 8 and the No. 3 bellows 81, the No. 2 bellows 8 connects the air inlet cavities of the two heat exchange tubes 1, and the No. 3 bellows 81 connects the air outlet cavities of the two heat exchange tubes 1, and the multiple heat exchange tubes 1 are connected by the No. 2 bellows 8 and the No. 3 bellows 81, so as to facilitate adaptive assembly in different granaries.

[0033] Working process: When using the heat exchange tube assembly to exchange heat for grain stored in the granary, according to the temperature change in the granary, if the temperature in the granary is low, which is common in cold weather, multiple heat exchange tubes 1 are directly connected, one end of the first heat exchange tube 1 is externally connected to the heating equipment, and the other end of the last heat exchange tube 1 is blocked. The heating equipment generates hot air that blows into the interior of the heat exchange tube 1, and the hot air flows through one of the multiple air holes through the sliding plate 12 into the interior of the diverter plate 14. At this time, a No. 2 magnetic block 13 on the sliding plate 12 is magnetically attracted to the No. 1 magnetic block 11 on one side of the heat exchange tube 1, and the connection adjustment assembly is connected to the diverter plate 14. The multiple No. 1 guide pipes 15 on the plate 14 are adjusted to be placed horizontally, and the multiple No. 1 guide pipes 15 are inserted into the grain pile. The hot air is discharged from the multiple No. 1 through holes of the No. 1 guide pipe 15 to increase the temperature in the granary. When the temperature in the granary exceeds the set value, the granary is opened to release heat, so that the temperature in the granary is maintained within the set temperature range; if the temperature in the granary is high, which is common in hot weather, the heating equipment can be replaced with a refrigeration equipment. The refrigeration equipment blows cold air into the interior of the heat exchange tube 1 and guides it into the granary for heat dissipation. When the heat dissipation starts, the granary can be opened for rapid ventilation until the granary maintains the set temperature range; When faced with a situation where some areas inside the granary are short of food and do not need heat exchange, the sliding plate 12 in the food-shortage area is manually adjusted to slide toward the top of the heat exchange tube 1. At this time, another No. 2 magnetic block 13 on the sliding plate 12 is magnetically attracted to the No. 1 magnetic block 11 on the top of the heat exchange tube 1, limiting the position of the sliding plate 12, and multiple No. 1 guide tubes 15 are also erected on the top of the heat exchange tube 1. The air holes of the heat exchange tube 1 are misaligned and blocked because the sliding plate 12 slides to the top of the heat exchange tube 1. The inside of the heat exchange tube 1 here can only be used for air intake from one end and air outlet from the other end. If it is necessary to use multiple No. 1 guide tubes 15 here, the sliding plate 12 can be slid in the opposite direction and reset, which plays a role in adjusting and controlling the closing state of the sliding plate 12 in the food-shortage area; When facing different grain partitions, one grain occupies a large area while the other grain occupies a small area, the sliding plate 12 can be manually adjusted to slide left or right, and the multiple No. 1 guide tubes 15 also slide accordingly, and one of the multiple air holes on the heat exchange tube 1 is connected to the sliding plate 12, so that the distance between the No. 1 guide tubes 15 on the multiple heat exchange tubes 1 increases or decreases, thereby facilitating heat exchange of grain in different areas and improving the heat exchange effect of the heat exchange tube assembly on grain; when exchanging heat for some deformed areas in the granary, in order to improve The heat exchange effect of grain stored in the granary is improved. According to the size of the storage space, the diverter plate 14 is rotated, and the limit groove 23 provided on the diverter plate 14 squeezes the limit plate 21 to slide up, and the limit plate 21 squeezes and contracts the elastic member 22. Then, another limit groove 23 on the diverter plate 14 corresponds to the limit plate 21, and the elastic force of the elastic member 22 is reset to squeeze the limit plate 21 into another limit groove 23, so as to adjust the angle of multiple No. 1 guide pipes 15 on the diverter plate 14, which is suitable for heat exchange in deformed areas. When exchanging heat in the granary, according to the size of the stored grain pile, the No. 1 extension pipe 3 is adjusted to slide on the No. 1 guide pipe 15, so that the No. 1 extension pipe 3 cooperates with the No. 1 guide pipe 15 to evenly exchange heat for the grain there, expand the heat exchange area, and the hot air or cold air entering the No. 1 guide pipe 15 can be discharged along the No. 1 through hole on the No. 1 guide pipe 15 and the No. 1 extension pipe 3, thereby achieving even heat exchange for grain piles of different sizes; When some areas in the granary are seriously damp due to geological influences, the connecting tube 4 connected to the flow control component is fixed on one side of the middle part of the diverter plate 14, and the No. 1 bellows 41 inside the connecting tube 4 is partially pulled out, and the No. 2 guide tube 42 cooperates with the No. 2 extension tube 43 to be inserted into the area where the grain is seriously damp. The flow control component is in the open state at this time, and then the heating equipment supplies hot air to multiple No. 1 guide tubes 15 and No. 1 bellows 41. Part of the hot air dries the local area that is seriously damp from the multiple No. 2 through holes on the No. 2 guide tube 42 and the No. 2 extension tube 43, which plays a role in strengthening the drying of the local area; when strengthening the drying of the local area, the connecting tube 4 is used to drive the threaded tube 51 to rotate in the interior of the fixed tube 5, so that the threaded tube 51 is away from One end of the No. 1 bellows 41 cancels the blockage of the internal channel of the fixed tube 5, and the hot air passes through the flow grooves on the side of the fixed tube 5 and the threaded tube 51 from the inside of the diverter plate 14, and the hot air enters the No. 1 bellows 41 and is sent to the No. 2 guide tube 42 and the No. 2 extension tube 43 for external discharge. When the No. 2 guide tube 42 and the No. 2 extension tube 43 are stopped from being used, the No. 2 extension tube 43 is slid and stored on the No. 2 guide tube 42, and the No. 2 guide tube 42 inserts the pulled No. 1 bellows 41 into the interior of the connecting tube 4 for storage, and the connecting tube 4 is rotated in the reverse direction, and the connecting tube 4 drives the threaded tube 51 to rotate in the reverse direction, and the end of the threaded tube 51 away from the No. 1 bellows 41 is pressed against the internal channel of the fixed tube 5 to block it, thereby playing the role of controlling and blocking the air inlet channel of the No. 1 bellows 41; When the gas after heat exchange is discharged, the two ends of the channel composed of multiple heat exchange tubes 1 are respectively located outside the granary, and the middle part of the channel is located inside the granary. The partition plate 6 divides the internal channel of the heat exchange tube 1 into two parts, one half of the air inlet chamber and the other half of the air outlet chamber. When the temperature is increased, the air inlet chamber of the heat exchange tube 1 at one end of the channel externally connected to the heating device and the air inlet chamber of the heat exchange tube 1 at the other end of the channel are blocked with a sealing plug 63, and the air outlet chamber at the heating device is blocked with another sealing plug 63, while the air outlet chamber at the other end is opened, and the hot air is passed into the interior of multiple No. 1 guide pipes 15 and No. 1 extension pipe 3 for discharge, and the hot air heats up the outer walls of the No. 1 reflux tube 61 and the No. 2 reflux tube 62, and the No. 1 reflux tube 61 and the No. 2 reflux tube 62 are inserted into the grain pile to exchange heat with the temperature of the grain. The gas after heat exchange in the tube 62 is discharged into the air outlet cavity by the cooperation of the ventilation component, and is discharged from the air outlet cavity far away from the end of the heating equipment. At the same time, when cooling the granary, the heating equipment can be replaced with a refrigeration equipment to achieve the effect of heat exchange of the return channel arranged in the granary; after the No. 1 return tube 61 and the No. 2 return tube 62 exchange heat with the granary, the gas is discharged from the guide ring 7 into the interior of the No. 1 return pipe 71, and then the No. 2 return pipe 72 cooperates with the guide block 73 to discharge the gas into the air outlet cavity, and finally the air outlet cavity discharges the heat-exchanged gas to the outside, which plays the role of reflux and external delivery of the heat-exchanged gas. At the same time, when the positions of multiple diverter plates 14 are adjusted, the No. 2 return pipe 72 made of soft material can cooperate with the No. 1 return pipe 71 made of hard material to ensure that the pipeline is not severely bent, thereby maintaining the effect of gas external delivery; When multiple heat exchange tubes 1 form a heat exchange channel, the second bellows 8 and the third bellows 81 are respectively fixed between two heat exchange tubes 1 as a connection. The heat exchange channel connected by the second bellows 8 and the third bellows 81 can realize the bending assembly of the heat exchange channel according to the height requirements of different areas, thereby improving the heat exchange effect in the granary; when assembling the heat exchange channel, the two heat exchange tubes 1 are connected by the second bellows 8 and the third bellows 81, the second bellows 8 connects the air inlet chambers of the two heat exchange tubes 1, and the third bellows 81 connects the air outlet chambers of the two heat exchange tubes 1. The multiple heat exchange tubes 1 are connected by the second bellows 8 and the third bellows 81, so as to facilitate adaptive assembly in different granaries; When there is vacant material placed in some areas of the granary, multiple 15 here can be slid up and stood upright with 12 to make room; when there is no need to make room and the heat exchange here needs to be stopped, the solenoid valve 9 in the normally open state in the sliding plate 12 can be controlled to be closed, so that the multiple No. 1 flow guide pipes 15 here do not exchange heat, thereby improving the control effect of heat exchange in some areas.
