Description

Technical Field

[0001] This utility model relates to auxiliary equipment for grain storage in grain warehouses, specifically to a local circulation cooling system for grain warehouses. Background Technology

[0002] Existing grain silo ventilation systems primarily use floor-mounted ventilation systems, which employ centrifugal fans to regulate airflow through galvanized steel or polymer-based ductwork laid on the ground. However, floor-mounted ventilation is ineffective at ventilating the inner walls of the grain silo. When storing raw grain, the edges of the grain pile (the inner walls) are more prone to dampness and mold growth. Molds (such as Aspergillus and Penicillium) multiply rapidly, and the decomposition of organic matter releases heat, causing overheating. Furthermore, condensation easily forms on the inner walls of the grain silo due to the temperature difference with the outside environment. Overheating and condensation problems can easily lead to mold growth, pests, and even grain loss. Utility Model Content

[0003] This application provides a localized circulation cooling system for grain storage, which can solve the problem that the existing grain storage ventilation structure has poor ventilation effect on the inner wall of the grain storage, which easily leads to heat generation and condensation at the edge of the grain pile (inner wall of the grain storage).

[0004] To solve the above technical problems, a local circulation cooling system for grain silos is provided, including a circulation ventilation duct. The circulation ventilation duct is arranged in a ring around the inner wall of the grain silo. A lifting mechanism is provided on the inner wall of the grain silo to drive the circulation ventilation duct to move vertically up and down. The circulation ventilation duct is provided with multiple exhaust holes. The circulation ventilation duct is connected to a temperature control system through a corrugated flexible hose. The temperature control system includes a fan and a refrigeration unit.

[0005] In one embodiment, the lifting mechanism includes a sliding part that slides linearly in the horizontal direction and is provided with a hydraulic cylinder for driving its sliding. A connecting rod is hinged between the sliding part and the circulating ventilation duct. A guide rod is provided vertically in the grain silo, and the circulating ventilation duct is slidably connected to the guide rod in the vertical direction.

[0006] In one embodiment, a slide rail is provided on the inner wall of the grain silo along the sliding direction of the sliding part, and the sliding part is slidably connected to the slide rail.

[0007] In one embodiment, multiple lifting mechanisms are provided.

[0008] In one embodiment, the sliding part is rod-shaped, and multiple connecting rods are hinged between the sliding part and the circulating ventilation duct.

[0009] In one embodiment, a support rod is fixedly provided on the circulating ventilation duct along its installation direction.

[0010] In one embodiment, the circulating ventilation duct is a triangular duct with its pointed corners pointing downwards.

[0011] In summary, the localized circulating cooling system for grain silos disclosed in this application has the following advantages compared to existing technologies: the circulating ventilation duct is located at the edge of the grain pile (on the inner wall of the grain silo) and moves up and down below the grain surface under the drive of the lifting mechanism. Cool air is delivered to the circulating ventilation duct through the corrugated hose via the temperature control system and discharged from the exhaust port, forming a micro-airflow that enhances ventilation, reduces grain temperature, and controls humidity, thereby preventing and addressing the problems of heat generation and condensation on the inner wall of the grain silo.

Detailed Implementation

[0020] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0022] Please see Figure 1 , Figure 2 A localized circulating cooling system for a grain silo includes a circulating ventilation duct 3, which is arranged in a ring around the inner wall of the grain silo 1. In one embodiment, the circulating ventilation duct 3 is horizontally rectangular.

[0023] Please see Figure 2 , Figure 3 A lifting mechanism is installed on the inner wall of the grain silo 1, located above the grain surface, to drive the circulating ventilation duct 3 to move vertically up and down below the grain surface. In one embodiment, the lifting mechanism includes a sliding part 7, which slides linearly along the inner wall of the grain silo 1 in a horizontal direction, and is equipped with a hydraulic cylinder 8 for driving its sliding. The hydraulic cylinder 8 is fixedly installed on the inner wall of the grain silo 1 along the sliding direction of the sliding part 7, and its telescopic rod end is fixedly connected to the sliding part 7 by welding. A connecting rod 9 is hinged between the sliding part 7 and the circulating ventilation duct 3. The upper end of the connecting rod 9 is hinged to the sliding part 7, and the lower end is hinged to the circulating ventilation duct 3. The hinge axis of the connecting rod 9 is located in the horizontal plane and perpendicular to the sliding direction of the sliding part 7. A guide rod 10 is fixed vertically in the grain silo 1, and a through hole is opened vertically on the circulating ventilation duct 3, which is slidably connected to the guide rod 10 through the through hole. This configuration allows the circulating ventilation duct 3 to move up and down via the horizontal sliding of the sliding part 7, resulting in a relatively stable structure. Furthermore, four guide rods 10 are positioned at the four corners of the circulating ventilation duct 3, further enhancing structural stability.

[0024] Please see Figure 3In one embodiment, the sliding part 7 is a square rod, and multiple parallel connecting rods 9 are hinged between the sliding part 7 and the circulating ventilation duct 3. In another embodiment, four lifting mechanisms are provided, each located above one of the four sides of the circulating ventilation duct 3, for synchronously driving the four sides of the circulating ventilation duct 3 to rise and fall. This arrangement results in a more stable structure.

[0025] Please see Figure 3 , Figure 4 , Figure 5 In one embodiment, a slide rail 2 is fixedly installed on the inner wall of the grain silo 1 along the sliding direction of the sliding part 7, and the sliding part 7 is slidably connected to the slide rail 2. This arrangement makes the sliding effect of the sliding part 7 more stable.

[0026] Please see Figure 2 , Figure 3 The circulating ventilation duct 3 is evenly provided with multiple exhaust holes 4, and the size of the exhaust holes 4 is smaller than the size of the raw grain. The circulating ventilation duct 3 is connected to a temperature control system 11 via a corrugated hose 5. The temperature control system 11 is fixedly installed on the grain silo 1. One end of the corrugated hose 5 is fixedly connected to the air outlet of the temperature control system 11, and the other end is fixedly connected to the circulating ventilation duct 3. The corrugated hose 5 can be relatively long to facilitate the raising and lowering of the circulating ventilation duct 3. The temperature control system 11 includes a fan and a refrigeration unit, which is used to deliver cold air from the corrugated hose 5 into the circulating ventilation duct 3 and discharge it from the exhaust holes 4 to form a micro-airflow, thereby enhancing the ventilation effect, reducing the grain temperature, and controlling humidity. The specific structure and principle of the temperature control system 11 are existing technologies and will not be described in detail here.

[0027] Please see Figure 3 In one embodiment, support rods 6 are fixed to the circulating ventilation duct 3 by welding along its setting direction. Furthermore, to accommodate the rectangular shape of the circulating ventilation duct 3, four support rods 6 are provided, located on the four sides of the rectangle and connected by welding. This arrangement allows the support rods 6 to provide support for the circulating ventilation duct 3, making its structure more stable and its load-bearing capacity stronger.

[0028] Please see Figure 6 In one embodiment, the circulating ventilation duct 3 is a triangular duct with its pointed corners pointing downwards, and its cross-section is triangular ring-shaped. With this configuration, when the circulating ventilation duct 3 moves downwards in the grain pile, its pointed corners can more easily push the grain to both sides, making it easier.
