Description

Technical Field

[0001] The invention relates to the technical field of granaries, and in particular to a granary ventilation and cooling device for use in Loess Plateau areas. Background Art

[0002] Granaries are special buildings for storing grain, which are used to store large quantities of grain. Since the humidity and temperature of grain should be paid special attention to during storage, in the field of grain storage, maintaining a suitable temperature and humidity environment in the granary is crucial to ensure the quality and safety of grain.

[0003] Most of the ventilation and cooling devices used in granaries have many limitations and are difficult to meet the needs of modern grain storage. On the one hand, some granaries rely on natural ventilation, and its effect is easily restricted by external climatic conditions. For example, in hot and humid seasons or periods of changeable climate, the temperature and humidity of natural wind are unstable, and the internal environment of the granary cannot be accurately controlled. This often causes problems such as mildew and pest breeding due to temperature and humidity fluctuations in grain, which seriously threatens the quality and safety of grain storage. On the other hand, although some simple mechanical ventilation systems can improve ventilation conditions to a certain extent, they have the disadvantage of uneven ventilation. Usually, only local air supply can be achieved, which easily forms ventilation dead corners, resulting in significant differences in temperature and humidity gradients inside the grain pile. In some areas, grain is in a high temperature and high humidity state for a long time due to poor ventilation, which accelerates grain aging and deterioration, causing huge economic losses. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and to propose a granary ventilation and cooling device for use in the Loess Plateau region.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 11 As shown, a granary ventilation and cooling device for the Loess Plateau region comprises a granary body 1 and a silo door 2 arranged on one side of the granary body 1. The top of the granary body 1 is a double-layer structure, including an inner top and an outer top. Both the inner top and the outer top are color steel plates with a central arch. The outer top and the inner top are spaced apart from each other. The staff can open the silo door 2 to enter and exit the granary body 1, and at the same time, the grain inside the granary body 1 can be transported by a cart. A mounting shell 3 is fixedly provided on the other side of the granary body 1. The mounting shell 3 is fixed to the outer side of the granary body 1 by bolts or welding. A refrigerator 11 is arranged inside the mounting shell 3. The input end of the refrigerator 11 is connected to the inside of the mounting shell 3. An air inlet is arranged on the side wall of the mounting shell 3. Two air supply components that cooperate with the output end of the refrigerator 11 are symmetrically rotated inside the granary body 1. When the refrigerator 11 is working, cold air is generated and circulated through the air supply components to supplement the cold and cool the inside of the granary body 1. A driving component for driving the two air supply components to rotate is arranged inside the mounting shell 3. The air supply assembly includes a connecting pipe 7, an outer air supply pipe 5, an inner air supply pipe 22, a connecting outer pipe 6 and a connecting inner pipe 23. The two ends of the outer air supply pipe 5 respectively pass through the outside of the granary body 1 and are rotatably connected to the granary body 1 through a bearing 12. One end of the inner air supply pipe 22 passes through the inside of the outer air supply pipe 5, and the other end of the inner air supply pipe 22 is connected to the connecting pipe 7 through a rotating joint 10. There are multiple connecting outer pipes 6 and they are respectively connected to the inside of the outer air supply pipe 5. There are multiple connecting inner pipes 23. One end of the multiple connecting inner pipes 23 is connected to the inside of the inner air supply pipe 22, and the other end extends into the inside of the connecting outer pipe 6. The output end of the refrigerator 11 is connected with a three-way pipe 9 through a pipeline. The connecting pipe 7 is connected to the three-way pipe 9. The cold air generated by the refrigerator 11 passes through the three The air is transported to the connecting pipe 7 by the through pipe 9 respectively, and transported to the inside of the air supply inner pipe 22 along the connecting pipe 7, and then transported to the connecting inner pipe 23 through the air supply inner pipe 22, and then transported to the connecting outer pipe 6 from the end of the connecting inner pipe 23, and then transported to the air supply outer pipe 5 through the connecting outer pipe 6, and then discharged from the other end of the air supply outer pipe 5. During the whole process, the air supply outer pipe 5 rotates under the action of the driving component, and the driving component drives the air supply outer pipe 5 to rotate reciprocatingly, thereby driving the air supply inner pipe 22, the connecting outer pipe 6 and the connecting inner pipe 23 to rotate as a whole. In this process, the connecting outer pipe 6 and the connecting inner pipe 23 will swing back and forth, that is, stir the grain stacked in the granary body 1, thereby improving the effect of supplementing cooling and cooling the stacked grain.

[0019] Further, the driving assembly includes a bidirectional screw rod 17 rotatably arranged inside the mounting shell 3 and a guide rod 8 fixedly arranged inside the mounting shell 3. A motor 13 for driving the bidirectional screw rod 17 to rotate is fixedly arranged on the outside of the mounting shell 3. Two moving seats 18 are symmetrically slidingly sleeved on the outside of the guide rod 8. The two moving seats 18 are respectively threadedly connected and matched with the bidirectional screw rod 17. One end of the outer surface of the two air supply outer pipes 5 is provided with a fixing plate 19. The surface of the fixing plate 19 is provided with a guide groove 21. One side of the two moving seats 18 is respectively rotatably provided with a guide column 20 matched with the guide groove 21. When in use, the staff starts the motor 13, and the motor 13 drives the bidirectional screw rod 17 to reciprocate. When the bidirectional screw rod 17 rotates clockwise, it drives the two moving seats 18 to move relative to each other (the moving seats 18 are guided by the guide rod 8). , stable horizontal movement), the relative movement of the two moving seats 18 drives the two guide columns 20 to move relative to each other, and under the cooperation of the guide columns 20 and the guide grooves 21, the two fixed plates 19 are relatively rotated, thereby driving the air supply outer tubes 5 to rotate relative to each other. The relative rotation of the two air supply outer tubes 5 will cause the connecting outer tube 6 and the connecting inner tube 23 to swing downward, and conversely, when the two-way screw rod 17 rotates counterclockwise, the two moving seats 18 will move away from each other, and then the two air supply outer tubes 5 will rotate away from each other, causing the connecting outer tube 6 and the connecting inner tube 23 to swing upward, thereby improving the effect of supplementing cooling and cooling the grain stacked in the granary body 1. During the whole process, there is no need to blow air inside the granary body 1, which effectively avoids the flying of dust in the granary under the action of the blowing, causing dust to enter the ventilation duct.

[0020] Furthermore, two return air ducts 4 are symmetrically fixed on the outside of the granary body 1, one end of the two return air ducts 4 is connected with one end of the air supply outer pipe 5 through a rotating joint 10, and the other end of the two return air ducts 4 is connected with the inside of the mounting shell 3 through the air inlet. During use, the air discharged through the air supply outer pipe 5 will enter the return air duct 4, and flow back to the mounting shell 3 through the return air duct 4, thereby achieving the effect of gas circulation and preventing dust and impurities in the external environment from easily gathering inside the refrigerator 11 through the refrigerator 11, thereby affecting the service life of the refrigerator 11.

[0021] Furthermore, a plurality of heat conducting plates 24 are fixedly sleeved on the outer surface of the connecting inner tube 23, and the outer surfaces of the plurality of heat conducting plates 24 are in close contact with the inner wall of the connecting outer tube 6. Through holes 25 are opened on the surfaces of the plurality of heat conducting plates 24, and the number of through holes 25 is multiple and distributed in a circular array. Under the action of the heat conducting plates 24, heat is effectively absorbed, that is, the heat in the stacked grains is absorbed, and when the wind flows in the connecting outer tube 6, it will pass through the through holes 25 on the surface of the heat conducting plates 24 in turn, thereby increasing the contact area between the wind and the heat conducting plates 24, so that the heat on the heat conducting plates 24 can be taken away during the wind circulation process, thereby improving the cooling effect.

[0022] Furthermore, the upper end of the mounting shell 3 is open and a top cover 16 is hingedly provided on one side of the upper end through a hinge 15. A handle 14 is fixedly provided on the outer surface of the top cover 16. The handle 14 is fixed to the surface of the top cover 16 by screws, which is convenient for the staff to open or close the top cover 16. A sealing gasket is provided between the top cover 16 and the mounting shell 3. The sealing gasket ensures the sealing effect inside the mounting shell 3 after the top cover 16 is closed. The staff can open the top cover 16 to inspect the components inside the mounting shell 3, such as inspecting the sealing of the pipeline connection and lubricating the rotating connection of the two-way screw 17, which effectively improves the service life of the entire device.

[0023] Furthermore, a heat dissipation coating is provided on the outer surfaces of the two return air ducts 4, and the two ends of the two return air ducts 4 are formed in a curved shape. By providing the heat dissipation coating, the air exchanges heat with the external environment during the return process through the return air ducts 4, which facilitates the initial heat dissipation and cooling of the return air.

[0024] Furthermore, one end of the connecting inner tube 23 is threadedly connected and fixed to the surface of the air supply inner tube 22, and one end of the connecting outer tube 6 is threadedly connected and fixed to the surface of the air supply outer tube 5. The staff first threadably connects and fixes the connecting inner tube 23 to the surface of the air supply inner tube 22 in sequence, and then respectively puts the connecting outer tube 6 on the outside of the connecting inner tube 23 and then threadably connects and fixes it to the surface of the air supply outer tube 5. The threads of the connecting inner tube 23 and the connecting outer tube 6 are tightened in the same direction, so that the connecting outer tube 6 will not cause the connecting inner tube 23 to loosen during the subsequent installation process.
