Abstract
Description
Technical Field
[0001] The present application relates to the technical field of grain storage, and in particular to a low-temperature grain storage for rice storage. Background Art
[0002] Among the existing rice storage technologies, low-temperature grain storage is widely used to ensure the quality of rice during storage and extend the storage period.
[0003] However, in actual use, the cooling mechanism of some existing low-temperature grain storages simply sends cold air into the interior of the grain storage. This cold air can often only contact the surface of the rice and cannot effectively penetrate into the interior of the rice.
[0004] Specifically, existing cooling mechanisms typically consist of a refrigeration system and simple cold air delivery pipes. The cold air generated by the refrigeration system is blown directly onto the rice grains within the grain storage via the delivery pipes. However, this cooling method has a significant problem: the distribution of the cold air within the grain storage is extremely uneven. Because the cold air is primarily concentrated on the surface of the rice grains, the temperature inside the grains drops slowly, resulting in uneven heat dissipation across the grains and reducing the cooling effect.
[0005] In view of the above problems, a low-temperature grain warehouse for rice storage is now designed. Utility Model Content
[0006] The embodiment of the present application provides a low-temperature grain storage for rice storage to solve the problem in the related art that some existing low-temperature grain storages simply send cold air into the interior of the grain storage, and the cold air can often only contact the surface of the rice, resulting in uneven heat dissipation effect on the overall rice.
[0007] In a first aspect, a low-temperature grain warehouse for storing rice is provided, comprising:
[0008] A grain depot and a support base arranged at the bottom of the grain depot, wherein a cooling mechanism is provided on the grain depot for performing low-temperature cooling on the grain depot;
[0009] The cooling mechanism includes a refrigeration system, an annular delivery pipe and a plurality of diverter pipes. The cold air outlet of the refrigeration system is connected to the annular delivery pipe for delivering cold air into the annular delivery pipe. The annular delivery pipe is arranged inside the low-temperature grain storage, and the plurality of diverter pipes are distributed in an annular shape on the annular delivery pipe.
[0010] A plurality of exhaust holes are provided on the diverter pipe.
[0011] In some embodiments, the refrigeration system includes a refrigerator, a cold air delivery pipe and a gas return pipe. The cold air outlet of the refrigerator is connected to the cold air delivery pipe, the other end of the cold air delivery pipe is connected to the annular delivery pipe, one end of the gas return pipe is connected to the grain storage, and the other end of the gas return pipe is connected to the return air port of the refrigerator.
[0012] In some embodiments, the annular delivery pipe includes three annular pipes nested in sequence and a plurality of transition pipes, the diameters of the three annular pipes decrease in sequence, and the three annular pipes are connected via a plurality of transition pipes;
[0013] The plurality of diversion pipes are respectively distributed in an annular shape on the tops of three annular pipes nested in sequence.
[0014] In some embodiments, the diversion pipe includes vertical pipes and inclined pipes that are connected to each other, and adjacent vertical pipes and inclined pipes are connected to each other and adapted to the shape of the grain storage.
[0015] In some embodiments, the bottom of the grain storage is conical, a feeding port is provided above the grain storage, and a discharge valve is provided at the bottom.
[0016] In some embodiments, a grain unloading trough is provided inside the support seat, and a conveying channel connected to the discharge valve is provided above the grain unloading trough;

[0018] In some embodiments, a support frame is provided on the outside of the grain storage, and a ladder is provided on one side of the support frame.
[0019] The present invention provides a low-temperature grain storage facility for rice storage. Through a refrigeration system, an annular delivery pipe, and a diversion pipe, cold air is evenly distributed throughout the facility, ensuring that both the interior and surface of the rice are adequately cooled. This significantly improves cooling efficiency and reduces the degradation of rice quality caused by uneven temperature.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0028] An embodiment of the present application provides a low-temperature grain storage for rice storage, which can solve the problem in the related art that some existing low-temperature grain storages simply send cold air into the interior of the grain storage, and the cold air can often only contact the surface of the rice, resulting in uneven heat dissipation effect on the overall rice.
[0029] See also Figure 1-Figure 3 A low-temperature grain storage for rice storage includes: a grain storage 1, and a support base 2 arranged at the bottom of the grain storage 1, the grain storage 1 is provided with a cooling mechanism 3, the cooling mechanism 3 is used to low-temperature cool the grain storage 1; the cooling mechanism 3 includes a refrigeration system 31, an annular conveying pipe 32 and a plurality of diversion pipes 33, the cold air outlet of the refrigeration system 31 is connected to the annular conveying pipe 32, and is used to send cold air into the annular conveying pipe 32, the annular conveying pipe 32 is arranged inside the low-temperature grain storage 1, and the plurality of diversion pipes 33 are distributed in an annular shape on the annular conveying pipe 32; the diversion pipe 33 is provided with a plurality of exhaust holes 4.
[0030] First, the refrigeration system 31 starts working, generating cold air. This cold air is sent into the annular conveying pipe 32 through the cold air outlet. The annular conveying pipe 32 is arranged inside the grain depot 1, and its design allows the cold air to form a circulating cold air belt inside the grain depot along the pipe.
[0031] Next, as the cold air flows through the annular conveying pipe 32, it is diverted into a number of diversion pipes 33. These diversion pipes 33 are distributed in a circular pattern around the annular conveying pipe 32, ensuring that the cold air is evenly distributed to every corner of the grain storage 1. The diversion pipes 33 allow the cold air to penetrate deeper into the rice grains, rather than just remaining on the surface.
[0032] Finally, the exhaust holes 4 on the diversion pipe 33 release the cold air into the grain storage 1, ensuring that the cold air can be released into the rice evenly and stably, achieving a low-temperature cooling effect.
[0033] Through the annular conveying pipe 32 and the diverter pipe 33, the cold air can be evenly distributed to every corner of the grain storage 1, ensuring that both the interior and the surface of the rice are fully cooled. This greatly improves the cooling efficiency and reduces the problem of rice quality degradation caused by uneven temperature.
[0034] The exhaust holes 4 on the shunt pipe 33 allow the cold air to penetrate deeper into the rice, achieving all-round cooling from the surface to the inside. This helps to maintain the freshness and quality of the rice during storage.
[0035] Because the cool air is evenly distributed and penetrates deeply into the rice, the refrigeration system does not need to work continuously at high intensity to maintain a low temperature environment. This reduces energy consumption and improves energy efficiency.
[0036] Specifically, the refrigeration system 31 in this embodiment includes a refrigerator, a cold air delivery pipe and a gas return pipe. The cold air outlet of the refrigerator is connected to the cold air delivery pipe, the other end of the cold air delivery pipe is connected to the annular delivery pipe 32, one end of the gas return pipe is connected to the grain warehouse 1, and the other end of the gas return pipe is connected to the return air port of the refrigerator.
[0037] Refrigeration system 31 consists of a refrigerator, a cold air delivery pipe, and a gas return pipe. The refrigerator generates cold air through its internal refrigeration cycle, which is then delivered to the cold air delivery pipe through the cold air outlet. The other end of the cold air delivery pipe is connected to the annular delivery pipe 32, which transports the cold air generated by the refrigerator into the grain warehouse 1.
[0038] To maintain a low temperature inside the granary, one end of a gas return pipe connects to the interior of granary 1 and the other end connects to the return air port of the refrigerator. Through this pipe, hot air and underutilized cold air from the granary are recovered and sent back to the refrigerator. After further cooling, they are then sent back into the granary, completing a complete cold air cycle.
[0039] The refrigeration system achieves efficient circulation of cold air through cold air delivery pipes and gas return pipes. This not only improves refrigeration efficiency but also ensures uniformity and stability of the temperature inside the grain warehouse.
[0040] By recycling and reusing the hot air and underutilized cold air inside the grain warehouse, this implementation scheme effectively reduces energy waste and improves resource utilization efficiency.
[0041] The refrigeration system utilizes a closed-loop system, preventing cold air leakage and environmental pollution. Furthermore, because the cold air creates a stable, low-temperature environment inside the grain warehouse, it helps reduce quality degradation and mildew during rice storage, thereby extending the rice's shelf life.
[0042] Furthermore, the annular conveying pipe 32 includes three annular pipes 321 nested in sequence and several transfer pipes 322. The diameters of the three annular pipes 321 decrease in sequence, and the three annular pipes 321 are connected through several transfer pipes 322; the several diversion pipes 33 are respectively distributed in an annular shape on the top of the three annular pipes 321 nested in sequence.
[0043] The annular delivery pipe 32 is composed of three annular pipes 321 nested in sequence and a plurality of transfer pipes 322, forming a multi-level, multi-channel cold air delivery network.
[0044] The diameters of the three annular tubes 321 decrease sequentially, forming a structure that gradually expands from the inside out. This allows for smoother flow of cold air within the annular tubes and more even distribution to every corner of the grain depot 1. Cold air enters the outermost annular tube 321 from the cold air outlet of the refrigeration system 31, then flows through the transfer tube 322 into the middle and innermost annular tubes 321, in sequence.
[0045] The transfer tube 322 serves as a bridge connecting different annular tubes 321, ensuring smooth circulation of cold air between different layers. It is arranged between the annular tubes 321 to minimize resistance to cold air flow and maximize uniformity of cold air distribution.
[0046] The diverter tubes 33 are arranged in a circular pattern on top of the three nested annular tubes 321, allowing the cold air to more directly reach the rice inside the grain storage 1, improving cooling efficiency. Furthermore, because the diverter tubes 33 are evenly distributed across the three different layers of annular tubes 321, the cold air can penetrate deeper into the rice, achieving all-round cooling from the surface to the interior.
[0047] Through the three nested annular tubes 321 and the plurality of transfer tubes 322, the cold air is distributed more evenly inside the grain depot 1, avoiding the accumulation of cold air in certain areas of the grain depot and the loss of cold air in certain areas, thereby improving the cooling effect.
[0048] The diversion pipes 33 are evenly distributed on the three different layers of the annular pipes 321, so that the cold air can contact the rice more directly and penetrate deeper into the rice, which greatly shortens the cooling time and improves the cooling efficiency.
[0049] Compared with the traditional single-layer annular conveying pipe design, the multi-layer annular conveying pipe design in this embodiment is more compact, which not only saves space, but also reduces the energy loss of cold air during the conveying process, thereby improving the overall efficiency of the system.
[0050] It should be noted that the diversion pipe 33 includes vertical pipes and inclined pipes that are connected to each other. Adjacent vertical pipes and inclined pipes are connected to each other and are adapted to the shape of the grain depot 1.
[0051] The inclined tubes allow the cold air to come into more direct contact with the rice in the grain warehouse and penetrate along the direction of rice stacking, thereby improving the utilization rate of the cold air.
[0052] The bottom of the grain depot 1 in this embodiment is conical, a feeding port is provided on the top of the grain depot 1, and a discharge valve is provided at the bottom.
[0053] The conical bottom facilitates smooth grain discharge. When grain needs to be discharged, the conical bottom guides the grain down the slope, preventing grain from accumulating and clogging at the bottom.
[0054] The feeding port is located above the grain depot 1 and is the main channel for grain to enter the depot.
[0055] The discharge valve is located at the bottom of the grain depot 1 and is a key component for controlling grain discharge. The design of the discharge valve makes the grain discharge process more flexible and controllable.
[0056] In one embodiment, a grain unloading trough 5 is provided inside the support base 2, and a conveying channel connected to the discharge valve is provided above the grain unloading trough 5;
[0057] A screw conveyor 6 is further provided inside the grain unloading trough 5 , and the screw conveyor 6 is used to transport the rice inside the grain unloading trough 5 to the outside.
[0058] A conveying channel connected to the discharge valve is provided above the grain unloading chute 5. When the discharge valve is opened, rice can smoothly enter the grain unloading chute 5 from the bottom of the grain depot 1 through the conveying channel.
[0059] To further improve the efficiency of rice discharge, a screw conveyor 6 is installed inside the grain unloading chute 5. This is a commonly used conveying device that uses the rotation of spiral blades to propel the material forward. Within the grain unloading chute 5, the spiral blades of the screw conveyor 6 are arranged along the bottom of the chute 5. When the screw conveyor 6 is activated, it effectively transports the rice inside the chute 5 to the outside.
[0060] The use of the grain unloading trough 5 and the conveying channel makes it possible for the rice to be discharged smoothly from the bottom of the grain depot 1, avoiding the problems of blockage and accumulation. At the same time, the addition of the screw conveyor 6 further improves the discharge efficiency of the rice.
[0061] In one embodiment, a support frame 7 is provided on the outside of the grain storage 1 , and a ladder 8 is provided on one side of the support frame 7 .
[0062] The support frame 7 enhances the structural stability of the grain storage 1 and also provides convenience for subsequent maintenance and repair work.
[0063] The combined use of support frame 7 and ladder 8 greatly facilitates subsequent maintenance and repair work. Workers can easily climb to the top or side of grain storage 1 using ladder 8 to perform necessary inspections and repairs on grain storage 1 and its ancillary equipment. This not only improves work efficiency but also reduces safety risks.
