Description

Technical Field

[0001] This utility model belongs to the field of controlled atmosphere guiding technology for grain warehouses, and particularly relates to a controlled atmosphere guiding skid device for grain warehouses. Background Technology

[0002] Controlled atmosphere storage (CAS) is currently the only green grain storage technology that can replace chemical fumigation and is being widely promoted and applied. When applying CAS technology, gas supply pipelines must be installed on the grain silo. There are two methods: one is to install a new gas circulation pipeline on the silo wall, and the other is to modify the existing circulation fumigation pipeline on the grain silo to meet the requirements of CAS multi-directional gas filling technology. Both of these methods of CAS pipeline installation and modification are not only large-scale projects but also costly, with a single silo costing 20,000-30,000 yuan. During the pipeline installation process, there is also significant damage to the silo walls, which also affects the overall airtightness and aesthetics of the grain silo.

[0003] The specific reason is that the existing piping systems in grain silos include fixed circulating fumigation piping systems, mobile circulating fumigation piping systems (used for fumigating and killing insects on grain), and circulating temperature-controlled piping systems (used for temperature control within the grain silos). These different piping systems (i.e., fixed circulating fumigation piping systems, mobile circulating fumigation piping systems, and circulating temperature-controlled piping systems) cannot be integrated with the controlled atmosphere system. Therefore, in actual operation, the only way to meet the controlled atmosphere requirements is to re-lay out and install gas supply pipelines within the grain silos using the methods described above.

[0004] Obviously, since it is impossible to provide a universal controlled atmosphere device that can be used with different pipeline systems, in actual operation, grain silos, especially multiple grain silos, need to modify their pipeline systems to meet the controlled atmosphere requirements. Therefore, the cost of modifying the pipeline system to meet the controlled atmosphere requirements is high, and the amount of work involved in the modification is large.

[0005] Therefore, if a controlled atmosphere device can be integrated with a fixed circulating fumigation pipeline system, a mobile circulating fumigation pipeline system, and a circulating temperature control pipeline system on a grain silo, the modified controlled atmosphere pipeline project can be avoided, greatly saving costs.

[0051] Example 1

[0052] like Figure 1-16 As shown, a controlled atmosphere guide skid device for grain silos includes a controlled atmosphere guide skid mechanism, which is used to connect to the piping system inside the grain silo 7 for controlled atmosphere installation. Specifically, this utility model discloses an improved controlled atmosphere guide skid mechanism that is compatible with existing fixed circulating fumigation piping systems, mobile circulating fumigation piping systems, and circulating temperature control piping systems on the grain silo 7. The advantage of this method is that during the controlled atmosphere process in the grain silo 7, a single controlled atmosphere guide skid device can be used in conjunction with the above three piping systems within the grain silo 7. Therefore, in actual operation, no modifications to the piping system of the grain silo 7 are required to accommodate controlled atmosphere installation.

[0053] Specifically, the modified atmosphere guide skid mechanism includes a fan 5 (the fan 5 is an existing conventional modified atmosphere fan), and the fan 5 is connected to a modified atmosphere guide pipe structure.

[0054] Specifically, the controlled atmosphere guide pipe structure is connected to the controlled atmosphere box 3, and the controlled atmosphere box 3 is connected to a plurality of controlled atmosphere connecting pipes 4 connected to the pipeline system on the grain silo 7; the controlled atmosphere guide pipe structure includes a first controlled atmosphere pipe 21 connected to the first air outlet position on the fan 5 (connected to the front end of the fan 5).

[0055] The second air outlet on the fan 5 is connected to the second controlled atmosphere duct 22 (connected to the center of the left side of the fan 5), and the second controlled atmosphere duct 22 is connected to the controlled atmosphere housing 3 (the controlled atmosphere housing 3 has a cavity inside). The specific connection method is as follows: the controlled atmosphere housing 3 is connected to the duct that connects to the second controlled atmosphere duct 22, and the duct and the second controlled atmosphere duct 22 are connected by a flange.

[0056] The first modified atmosphere duct 21 is connected to the third modified atmosphere duct 24; the third modified atmosphere duct 24 is connected to the first modified atmosphere duct 21; the second modified atmosphere duct 22 is connected to the first connecting pipe 27 and the second connecting pipe 28 (set at intervals on the left and right); the third modified atmosphere duct 24 is connected to the third connecting pipe 25.

[0057] The modified atmosphere box 3 is equipped with four modified atmosphere connecting pipes 4, namely the first modified atmosphere connecting pipe 4, the second modified atmosphere connecting pipe 4, the third modified atmosphere connecting pipe 4 and the fourth modified atmosphere connecting pipe 4.

[0058] Meanwhile, ball valves 41 are respectively installed and connected to the first, second, third, and fourth modified atmosphere connecting pipes 4.

[0059] A control valve 211 is installed and connected to the air outlet end of the first controlled atmosphere duct 21 (the control valve 211 only controls the air outlet of the first controlled atmosphere duct 21). At the same time, a first gate valve 221 and a second gate valve 23 are respectively installed and connected to the second controlled atmosphere duct 22 and the third controlled atmosphere duct 24; the first gate valve 221 is located between the first connecting pipe 27 and the second connecting pipe 28.

[0060] The second gate valve 23 is located on the left side of the third connecting pipe 25.

[0061] Meanwhile, the first connecting pipe 27, the second connecting pipe 28, and the third connecting pipe 25 are respectively equipped with the first valve 271, the second valve 281, and the third valve 26.

[0062] The aforementioned controlled atmosphere skid device for grain silo 7 also includes a mobile trolley 1; the controlled atmosphere skid mechanism is mounted on the mobile trolley. The mobile trolley 1 includes a seat and several rollers mounted on the bottom of the seat; a push rod is mounted on the seat. During operation, the operator moves the mobile trolley by pushing it.

[0063] Similar to the existing fan 5 control operation, an electrical control box 6 for controlling the operation of the fan 5 is installed on the mobile trolley, and the operation of the motor on the fan 5 is controlled by the control circuit inside the electrical control box 6.

[0064] Those skilled in the art can understand how the fan 5 disclosed in this utility model is controlled by consulting technical manuals and dictionaries.

[0065] Example 2

[0066] like Figure 1-16 As shown in the figure, this embodiment discloses the controlled atmosphere operation mode of the grain silo 7 controlled atmosphere guide skid device in conjunction with the circulating temperature control pipeline system, as detailed below:

[0067] like Figure 2 As shown, each controlled atmosphere connecting pipe 4 (specifically, the first controlled atmosphere connecting pipe 4 to the fourth controlled atmosphere connecting pipe 4) is connected to the air vent 711 of the grain silo via hose A (specifically, connected to the air vent 711 at the lower end of the grain silo 7). The carbon dioxide tank is connected to the first connecting pipe 27, and the second connecting pipe 28 is connected to the air inlet 713 at the upper end of the grain silo via hose B.

[0068] The first gate valve 221 and the second gate valve 23 on the gas-controlled flow guide skid mechanism are closed, the third valve 26 on the third pipe 25 is closed, and the remaining valves are in the open state.

[0069] During the controlled atmosphere process, carbon dioxide is connected through the first pipe 27, passes through the controlled atmosphere box 3, and enters the ventilation port 711 through the controlled atmosphere connecting pipe 4 and the hose A (carbon dioxide enters the ventilation network at the bottom of the grain pile in the grain silo from the ventilation port 711) and is discharged into the grain silo 7.

[0070] Turn on the fan 5, and the fan 5 will exhaust the air (the exhaust gas will be discharged from the first controlled atmosphere pipe 21). Specifically, the fan 5 will exhaust the air, and the exhaust gas in the grain silo 7 will be discharged from the air inlet at the top of the grain silo 7 and through the hose B, the fan 5, and the first controlled atmosphere pipe 21.

[0071] The above method achieves the modified atmosphere mode of carbon dioxide charging from the bottom and discharging from the top.

[0072] like Figure 3 As shown, a flexible hose C is connected to the air inlet 713, and the air inlet end of the flexible hose C is connected to the output port of the nitrogen generator to achieve nitrogen charging. Similarly, when the fan 5 is turned on, the exhaust gas in the grain silo 7 is discharged from the vent 711, through the flexible hose A, the second controlled atmosphere pipe 22, and the first controlled atmosphere pipe 21 (the corresponding valves are opened and closed accordingly).

[0073] The above method achieves nitrogen or carbon dioxide top-filling and bottom-exhausting gas regulation.

[0074] like Figure 4 As shown, a flexible hose D is connected to the third connecting pipe 25. The flexible hose D is connected to the air inlet 713. The fan 5 is turned on to draw air. The airflow in the grain silo 7 enters the fan 5 through the ventilation port 711, the flexible hose A, the controlled atmosphere box 3, and the second controlled atmosphere pipe 22. The airflow then passes through the third connecting pipe 25 and the flexible hose D from the air outlet of the fan 5 and returns to the air inlet 713 of the circulating temperature control pipe system 71, thus realizing the circulating mode of the grain silo 7.

[0075] like Figure 5 As shown, the toxic gas at the grain surface in the grain silo 7 is directly extracted by the exhaust fan 5. Specifically, a flexible hose E is connected to the second connecting pipe 28, and the other end of the hose E is connected to the air inlet 713. When the fan 5 is turned on, the toxic gas is extracted from the air inlet 713 and discharged directly from the first gas regulation pipe 21 through the fan 5. This achieves the grain surface detoxification mode.

[0076] like Figure 6 As shown, the toxic gas at the bottom of the grain silo 7 is directly extracted by the blower 5, and discharged through the vent 711, hose A, second controlled atmosphere pipe 22, blower 5, and first controlled atmosphere pipe 21. This achieves a toxic gas exhaust mode at the bottom of the grain pile.

[0077] Example 3

[0078] like Figure 1-16 As shown in the figure, this embodiment discloses the controlled atmosphere guide skid device of grain warehouse 7 working in conjunction with the mobile circulating fumigation pipeline system, as follows:

[0079] like Figure 7 As shown, a flexible hose F is connected to the second connecting pipe 28 and the mobile circulating fumigation pipeline system 9 (the vent 711 of the grain silo 7 is also connected to the controlled atmosphere pipe via flexible hose A). The first gate valve 221 and the second gate valve 23 are closed. The first connecting pipe 27 is connected to the carbon dioxide tank, allowing for bottom-filling of carbon dioxide. The blower 5 is turned on to exhaust the waste gas from the grain silo 7 through the mobile circulating fumigation pipeline system and the first controlled atmosphere pipe 21. During this process, the first valve 271, the second valve 281, and the control valve 211 are open, while the remaining valves are closed. This achieves the bottom-filling and top-exhausting mode of carbon dioxide.

[0080] like Figure 8 As shown, one end of a flexible hose G is connected to the mobile circulating fumigation pipeline system 9, and the other end is connected to the carbon dioxide tank or nitrogen tank to achieve the nitrogen or carbon dioxide top-filling and bottom-discharging mode.

[0081] Turn on the fan 5. Similarly, the exhaust gas in the chamber is discharged through the vent 711, through the hose A, through the second controlled atmosphere pipe 22, and through the first controlled atmosphere pipe 21 (the corresponding valves are opened and closed accordingly).

[0082] like Figure 9 As shown, one end of a flexible hose H is connected to the third connecting pipe 25, and the other end is connected to the mobile circulating fumigation pipeline system 9. When the blower 5 is turned on, the exhaust airflow passes through the flexible hose H and recirculates back into the mobile circulating fumigation pipeline system 9 before entering the grain silo 7, thus achieving a downward circulating mode.

[0083] like Figure 10 As shown, a flexible hose I is connected to the mobile circulating fumigation pipeline system 9, the blower 5 is turned on, and the corresponding valve is closed, so that the mobile circulating fumigation pipeline system 9 can be used to exhaust and detoxify the upper part of the grain surface of the grain silo 7.

[0084] like Figure 11 As shown, turn on the fan 5 to exhaust air from the bottom of the grain bin 7, thereby achieving air extraction and detoxification of the bottom surface of the grain pile.

[0085] Example 4

[0086] like Figure 1-16 As shown in the figure, this embodiment discloses the controlled atmosphere guide skid device of grain warehouse 7 working in conjunction with the fixed circulating fumigation pipeline system 10, as follows:

[0087] like Figure 12 As shown, a flexible hose K is connected to the second connecting pipe 28 and the circulating fan 8 of the grain silo 7 (specifically on the air inlet pipe of the circulating fan 8); similarly, four flexible hoses A are connected to the first to the fourth regulating air pipes and the ventilation opening 711 of the grain silo 7.

[0088] Connect the carbon dioxide tank to the first connecting pipe 27. During the controlled atmosphere process, carbon dioxide is charged into the grain silo 7 from the bottom through the first connecting pipe 27 (same principle as above). Turn on the blower 5, and the exhaust gas in the grain silo 7 is discharged through the hose K and blower 5 into the first controlled atmosphere pipe 21. This realizes the carbon dioxide charging and discharging mode.

[0089] like Figure 13 As shown, a flexible hose L is connected to the circulating fan 8, and the flexible hose L is connected to the output port of a nitrogen generator or carbon dioxide tank, so that the grain silo 7 is filled with air from the top.

[0090] Similarly, after turning on fan 5, the exhaust gas inside the chamber is drawn out through vent 711 and hose A, achieving an upward charging and downward exhaust mode.

[0091] like Figure 14 As shown, after turning on the fan 5, the bottom of the grain silo 7 can be vented. Specifically, the toxic gas at the bottom of the grain surface in the grain silo 7 is discharged from the vent 711, the hose A, the fan 5, and the first controlled atmosphere pipe 21.

[0092] like Figure 15 As shown, a flexible hose M is connected to the third connecting pipe 25 and the air inlet pipe of the circulating fan 8, so that when the fan 5 is turned on, the airflow under the grain surface of the grain bin 7 is drawn out by the fan 5 and sent to the upper part of the grain surface of the grain bin 7 via the fan 8, realizing the downward circulation mode of the grain bin 7.

[0093] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
