Description

Technical Field

[0001] This invention relates to the field of grain storage engineering technology, and in particular to a bamboo-joint storage system. Background Technology

[0002] Grain storage systems, such as shallow circular silos, are equipped with various systems to improve storage conditions, ensure grain quality, and slow down aging. These systems include mechanical ventilation, recirculating fumigation, grain cooling, grain condition monitoring and control, nitrogen controlled atmosphere, and grain surface cooling. Each system involves a wide variety of equipment, complex piping layouts, and high construction and installation costs. Furthermore, maintenance is extensive when problems arise, and true intelligent control is not feasible.

[0003] To reduce costs, new warehouse designs have incorporated merging technologies, such as combining refrigeration and ventilation systems into a single, centrally controlled system. This increases the intelligence of warehousing and reduces costs. However, this two-in-one system is far from meeting the demands of intelligent warehousing development. Summary of the Invention

[0004] In view of this, the purpose of this invention is to address the shortcomings of the prior art by providing a bamboo-joint storage system that integrates mechanical ventilation, circulating fumigation, grain cooling, nitrogen atmosphere conditioning, grain surface ventilation, and grain surface cooling into one system, achieving fully intelligent control, low construction cost, and flexible operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bamboo-joint storage system is installed on a storage body. Air vent 1 and air vent 2 are respectively provided at the bottom and top of the storage body. Air vent 3, air vent 4, and air vent 5 are sequentially arranged on the upper outer periphery of the storage body. Air vent 3 and air vent 5 are located at the grain loading line position of the storage body. The system is characterized by including a refrigeration unit, a fan 1, and a fan 2. Air vent 4 is connected to branch line 1, branch line 1 is connected in parallel to branch line 2 and branch line 3, branch line 3 is sequentially connected to fan 1 and branch line 4, and branch line 4 is connected in parallel to branch line 5 and branch line 6. Branch line 5 is connected to pipe 1 and pipe 2 in parallel. Pipe 1 is connected to vent 1. Pipe 2 is connected to pipe 3 and pipe 4 in parallel. Pipe 3 is connected to pipe 5, pipe 6 and pipe 7 in parallel. Pipe 6 is connected to pipe 8 and pipe 9 in parallel. Pipe 8 is connected to vent 3. Pipe 7 and pipe 9 are respectively connected to the refrigeration unit. Pipe 4 connects sequentially to ventilation fan 2, pipe 10, and the refrigeration unit; Five ducts connected to five ventilation openings.

[0006] Furthermore, the pipeline is connected to the air intake pipeline.

[0007] Furthermore, bidirectional valves are installed on branch line 1, branch line 4, branch line 5, pipeline 2, pipeline 3, pipeline 6, pipeline 7, pipeline 10, air intake pipeline, and pipeline 9.

[0008] Furthermore, branch six is ​​connected to branch seven.

[0009] Furthermore, the branch seven is connected to the nitrogen generation unit.

[0010] Furthermore, the branch two-way connected circulating fumigation drug generator.

[0011] The beneficial effects of this invention are: 1. This application discloses a bamboo-joint storage system that integrates six functions into one: mechanical ventilation of grain piles, circulating fumigation, grain cooling, nitrogen atmosphere conditioning, grain surface ventilation, and grain surface cooling. This forms an intelligent system that can realize grain pile ventilation, grain pile cooling, grain surface ventilation, grain surface cooling, nitrogen atmosphere conditioning, and circulating fumigation, greatly simplifying the operating and construction costs of the storage system.

[0012] 2. During the grain pile cooling and grain surface cooling operations, when the outside temperature is below 20℃, natural ventilation can be increased to reduce energy consumption; when the outside temperature is relatively high, a low-temperature circulation system is used, resulting in low energy consumption and high flexibility for the entire system.

[0013] 3. Nitrogen modified atmosphere fumigation and circulating fumigation use the same system. The difference is that the connected pipeline is either a nitrogen generation pipeline or a circulating fumigation chemical generator. The operation is flexible and the energy consumption is low.

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments. Example 1

[0017] A bamboo-joint storage system, see Figure 1 As shown, the ventilation and fumigation system, installed on the silo body 1, serves as the silo body for grain storage. In this embodiment, it is a 20℃ low-temperature silo, 18*18m in size, with 32 ground ventilation cages installed at the bottom of each silo and 4 ventilation openings at the top of each silo, providing a unit ventilation volume of 5m³. 3 / h·t.

[0018] The bottom and top of the silo body 1 are respectively equipped with air inlet 1 2 (air inlet for ground ventilation cage) and air inlet 2 3 (ventilation opening on the top of the silo). The upper outer perimeter of the silo body 1 is provided with air inlet 3 4, air inlet 4 5 and air inlet 5 9 in sequence, wherein air inlet 3 4 and air inlet 5 9 are located at the grain loading line position inside the silo. The bamboo-joint storage system includes a refrigeration unit 6, a fan 1 7 and a fan 2 8. Air inlet 4 5 is connected to branch 1 51, branch 1 51 is connected in parallel to branch 2 52 and branch 3 53, branch 3 53 is connected in sequence to fan 1 7 and branch 4 54, and branch 4 54 is connected in parallel to branch 5 55 and branch 6 56. Branch 55 is connected in parallel to pipe 1 21 and pipe 2 22. Pipe 1 21 is connected to vent 1 2. Pipe 2 22 is connected in parallel to pipe 3 23 and pipe 4 24. Pipe 3 23 is connected in parallel to pipe 5 25, pipe 6 26 and pipe 7 27. Pipe 6 26 is connected in parallel to pipe 8 41 and pipe 9 29. Pipe 8 41 is connected to vent 3 4. Pipe 7 27 and pipe 9 29 are respectively connected to refrigeration unit 6. Pipe 424 is connected in sequence to ventilation fan 28, pipe 1028 and refrigeration unit 6; Pipeline 5.25 connected to ventilation opening 5.9; Pipeline 28 connects to intake pipe 281.

[0019] Branch road 656 connects to branch road 7561.

[0020] Two-way valves are installed on branch line 1 (51), branch line 4 (54), branch line 5 (55), pipeline 2 (22), pipeline 3 (23), pipeline 6 (26), pipeline 7 (27), pipeline 10 (28), air intake pipeline 281, pipeline 9 (29), and branch line 7 (561).

[0021] For details on the process of using the bamboo-joint storage system of this application for grain pile ventilation, please refer to [link / reference needed]. Figure 2 As shown by the arrows, the natural air input through the intake pipe 281 passes through the fan 28 and enters the pipe 4 24, where it splits into two paths. One path passes through the pipe 22 and the pipe 1 21 and enters the vent 1 2, moving upwards along the grain pile inside the silo 1. The other path passes through the pipe 3 23 and then splits into two paths. One path passes through the pipe 5 25 and enters the vent 5 9, while the other path passes through the pipe 6 26 and the pipe 8 41 and enters the vent 3 4, moving upwards along the grain pile and finally carrying the heat from the grain pile out through the vent 2 3, thus achieving the grain pile ventilation operation. Example 2

[0022] The bamboo-joint storage system described in Example 1 is used to achieve refrigeration of the grain pile. For details, please refer to [link to example]. Figure 3 As shown by the arrows, if the outside temperature is higher than 20℃, the cold air output from the evaporator of the refrigeration unit 6 passes through fan 28, enters pipe 424, pipe 22, and pipe 121, and enters vent 12. It then rises along the grain pile inside the silo 1. The hot air comes out from vent 59 and vent 34, and returns to the air inlet of the refrigeration unit 6 from vent 59 along pipe 525 and pipe 727. The hot air from vent 34 also returns to the air inlet of the refrigeration unit 6 along pipe 841 and pipe 929, thus achieving low-temperature circulating ventilation throughout the grain pile.

[0023] When the outside temperature is below 20℃, the air intake pipe 281 can also be opened to reduce energy consumption. Example 3

[0024] The bamboo-joint storage system of Example 1 is used to achieve surface ventilation of grain. See [link / reference]. Figure 4 As shown by the arrow, the natural air input through the intake pipe 281 passes through pipe 10 28 and fan 2 8, and then enters pipe 4 24 and pipe 3 23, splitting into two paths. One path passes through pipe 5 25 and enters vent 5 9, while the other path passes through pipe 6 26 and pipe 8 41 and enters vent 3 4, driving the hot air from the grain surface to be discharged from vent 2 3, thus achieving ventilation of the grain surface. Example 4

[0025] The bamboo-joint storage system of Example 1 is used to achieve grain surface refrigeration operations. See [link to example]. Figure 5 As shown by the arrow, if the outside temperature is below 20℃, the cold air output from the evaporator of the refrigeration unit 6 and the natural air input from the air inlet pipe 281 pass through pipe 10 28, fan 2 8, pipe 4 24 to pipe 3 23, pipe 5 25 and enter the air outlet 5 9, which drives the hot air on the grain surface. One path is discharged through the air outlet 2 3, and the other path is returned to the air inlet of the evaporator of the refrigeration unit 6 through the air outlet 3 4, pipe 8 41 and pipe 9 29, thus realizing the cooling cycle of the grain surface.

[0026] If the outside temperature is higher than 20°C, the intake pipe 281 needs to be closed and only the refrigeration cycle should be used. Example 5

[0027] Nitrogen operations are implemented using the bamboo-joint storage system of Example 1, see [link to example]. Figure 6 As indicated by the arrow, branch line 7 561 connects to the nitrogen generator. The nitrogen generated by the nitrogen generator is controlled by valve K1002. When valve K1002 is opened, the nitrogen enters branch line 6 56 through branch line 7 561, and then enters vent 1 2 through branch line 5 55 and pipe 1 21. Then it goes up along the grain pile, with one path leading to the exhaust from vent 2 3, and the other path leading to vent 4 5, branch line 1 51, branch line 3 53, blower 1 7, branch line 4 54, and branch line 5 55, forming a nitrogen circulation.

[0028] In addition, the second branch 52 of the bamboo-joint storage system of this application is connected to the circulating fumigation chemical generator. During the circulating fumigation operation, the seventh branch 561 is closed and the second branch 52 is opened to carry out the circulating fumigation operation.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
