Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a constant temperature grain storage silo that can efficiently control temperature. Background Technology

[0002] When storing grain, existing silos are highly susceptible to external environmental influences due to the thin walls and good thermal conductivity of the metal silos. This is especially true in northern regions where temperature fluctuations are significant. It is difficult to maintain a constant temperature suitable for grain storage inside the silos, leading to frequent occurrences of mold growth (due to large temperature differences between day and night causing the grain to become damp and prone to mold) or dormancy (due to excessively low temperatures causing the grain to become dormant), which greatly affects the effectiveness of grain storage. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a constant-temperature grain storage silo. This silo can not only monitor the temperature inside the silo in real time, but also automatically adjust the temperature inside the silo based on the monitored values.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

The top of the cylindrical body is provided with a grain inlet and an exhaust outlet, and the bottom is a conical structure with a grain outlet. A pair of air ducts extending upwards and adhering to the wall are sealed through the bottom of the cylindrical body from the outside to the inside. An air conditioning system connected to the air ducts is provided outside the cylindrical body, and a controller is communicated with the air conditioning system. A pressurizing fan and a temperature sensing probe are communicated with the controller. The pressurizing fan is located on the air duct between the air conditioning system and the cylindrical body. There are two temperature sensing probes that are sealed through the cylindrical body from top to bottom.

[0006] Furthermore, the upper end of the air duct is the air outlet, and a partition beam mesh cover is provided on it. The partition beam mesh cover can not only ensure that the air duct blows hot or cold air into the cylinder to regulate the temperature, but also effectively prevent grain from falling into the air duct.

[0007] Furthermore, to make the temperature inside the cylinder more uniform, multiple horizontal branch pipes can be installed at intervals along the height direction between the two air ducts located inside the cylinder. The diameter of the horizontal branch pipe is smaller than that of the air duct, and the two ends of the horizontal branch pipe are respectively connected to the two air ducts. Each horizontal branch pipe has multiple downward-facing air outlet holes at intervals along the length direction.

[0008] Furthermore, in order to maintain the temperature inside the cylinder for a long time, a layer of insulating cotton can be placed on the outer wall of the cylinder.

[0009] The utility model discloses a advantage lies in the sealing pipe and temperature sensing probe rod are arranged on the cylinder, so that the temperature in the cylinder can be monitored in real time, and the controller, air conditioning system, pressure fan are cooperated to blow hot air or cold air into the cylinder in time, so that the temperature in the cylinder can be changed easily and quickly, the temperature in the cylinder is always kept at a constant temperature suitable for grain storage, the grain mildewing or dormancy phenomenon is avoided, and good grain storage effect is ensured.

[0013] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0014] As Figures 1-3 shown, the constant-temperature grain storage silo of the utility model, including the cylinder 1, and setting in the cylinder 1 on the support 2 of stable support effect, with cover in the outer wall of cylinder 1 can high-efficiency heat preservation heat preservation cotton layer 3 (heat preservation cotton layer 3 can heat preservation, also can keep cold). The cylinder 1 top is equipped with the grain inlet 4 and exhaust port 5, and the cylinder 1 bottom is the conical structure of big up small, and is equipped with the grain outlet 6 at the conical bottom, and the grain inlet 4 and the grain outlet 6 are all with the sealing cover that can open and close, and the exhaust port 5 is the elbow structure that is bent downward, prevents rain when rainwater from exhaust port 5 falls into the cylinder 1.

[0015] The bottom of cylinder 1 is sealed and penetrates a pair of air pipes 7 from outside to inside, and the two air pipes 7 extend along the inner wall of the cylinder 1 to the top of the inner cavity, and the upper end is the air outlet end of the open structure; The air conditioning system 8 connected with the air pipe 7 is arranged outside the cylinder 1, and the controller 9 is in communication connection with the air conditioning system 8, the pressure fan 10 and the temperature sensing probe 11 in communication connection are arranged on the controller 9, the pressure fan 10 is arranged on the air pipe 7 between the air conditioning system 8 and the cylinder 1, and the temperature sensing probe 11 is two, and is sealed and penetrated into the cylinder 1 from top to bottom.

[0016] The temperature of the stored grain crops in the cylinder 1 is monitored in real time by the temperature sensing probe 11. When the temperature sensing probe 11 detects that the temperature in the cylinder 1 is too high (especially in summer when the temperature is high, the temperature in the cylinder is prone to be too high), it transmits a high-temperature signal to the controller 9. After the controller 9 receives the high-temperature signal, it automatically controls the air conditioning system 8 to start cooling and controls the pressurized fan 10 to work at the same time, so that the cold air generated by the air conditioning system 8 is blown into the cylinder 1 through the air pipe 7, thereby achieving the cooling of the inner cavity of the cylinder 1, avoiding the mold phenomenon of the stored grain crops, and keeping the grain crops at a constant temperature suitable for storage, so as to ensure good grain storage effect. When the temperature sensing probe 11 detects that the temperature in the cylinder 1 is too low (especially in winter in the northeast where the temperature is very low, the temperature in the cylinder is prone to be too low), it transmits a low-temperature signal to the controller 9. After the controller 9 receives the low-temperature signal, it automatically controls the air conditioning system 8 to start heating and controls the pressurized fan 10 to work at the same time, so that the hot air generated by the air conditioning system 8 is blown into the cylinder 1 through the air pipe 7, thereby achieving the heating of the inner cavity of the cylinder 1, avoiding the dormancy phenomenon of the stored grain crops, and keeping the grain crops at a constant temperature suitable for storage, so as to ensure good grain storage effect.

[0017] Further, in order to prevent the grain from falling into the air pipe 7 from the air outlet end of the air pipe 7, a partition beam net cover 12 should also be provided on the air outlet end of the air pipe 7. The mesh number of the partition beam net cover 12 is determined according to the grain crops to be stored in the cylinder 1, as long as the mesh diameter is smaller than the particle diameter of the grain crops, which not only can ensure that the air outlet end of the air pipe 7 blows hot air or cold air to adjust the temperature, but also can effectively prevent the grain from falling into the air pipe 7.

[0018] Further, in order to make the temperature in the cylinder 1 more uniform when it is heated or cooled, a plurality of horizontal branch pipes 13 can be arranged in the height direction between the two air pipes 7 in the cylinder 1. The diameter of the horizontal branch pipe 13 is smaller than that of the air pipe 7, and the two ends are respectively communicated with the two air pipes 7. A plurality of air outlet holes 14 with downward holes are arranged on each horizontal branch pipe 13 along the length direction. The downward hole air outlet hole 14 not only can make the heating or cooling of the air in the cylinder 1 more comprehensive, but also can effectively prevent the grain crops from entering the horizontal branch pipe 13. In addition, the horizontal branch pipe 13 is a thin pipe, so it will not affect the falling of the grain crops when the cylinder 1 stores the grain, and the grain stored in the cylinder 1 will surround the horizontal branch pipe 13 up and down, so the horizontal branch pipe 13 will not be bent by the grain crops.

[0019] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directionality indications also change accordingly.
