Description

Technical Field

[0001] The invention relates to the technical field of food safety storage equipment, and in particular to an emergency isolation cabin in a gas-controlled granary. Background Art

[0002] A controlled atmosphere granary is a granary that artificially changes the gas composition in the granary to control the ratio of oxygen and carbon dioxide, thereby achieving the purpose of killing insects and inhibiting mildew and delaying changes in grain quality. Specifically, a controlled atmosphere granary uses nitrogen gas conditioning technology to replace the air inside the grain pile with high-purity nitrogen to create a low-oxygen environment, using the principle of natural hypoxia to effectively prevent and kill pests, while delaying changes in grain quality.

[0003] The core of the gas-controlled granary is to achieve grain storage safety by adjusting the gas composition in the granary. Specifically, nitrogen gas-controlled technology uses nitrogen generated by nitrogen-generating equipment and transports it to the granary through a pipeline network, so that the grain pile reaches and maintains a certain nitrogen concentration ratio. When the nitrogen concentration is above 95%, it can effectively inhibit the oxygen utilization of pests, thereby achieving the effect of killing or preventing insects; when the nitrogen concentration is above 98%, it can be used in granaries with serious pest damage.

[0004] However, during the daily maintenance and equipment inspection of the gas-controlled grain silo, due to the special gas environment in the silo, once an accident occurs to the workers, such as fainting due to lack of oxygen or gas poisoning, it is difficult to get effective rescue in a short time. At present, there is a lack of equipment in the gas-controlled grain silo that can quickly provide a safe space for people in distress to wait for further rescue. Summary of the invention

[0005] The purpose of the present invention is to provide an emergency isolation cabin in a controlled atmosphere grain silo to solve the above technical problems.

[0006] The invention provides an emergency isolation cabin in a controlled atmosphere grain silo, comprising a cabin body arranged in the grain silo and placed above the piled grains, the cabin body being connected to an air supply mechanism and provided with a quick-opening door for closing the cabin body.

[0031] Example 1

[0032] like Figure 1-Figure 5 As shown:

[0033] An emergency isolation cabin in a controlled atmosphere grain silo comprises a cabin body 2 arranged in the grain silo 1 and placed above the piled grains, the cabin body 2 is connected to an air supply mechanism, and the cabin body 2 is provided with a quick-opening door for closing the cabin body 2.

[0034] The air supply mechanism is composed of a fan 31 and a gas pipeline 32 . The fan 31 is arranged outside the granary 1 . One end of the gas pipeline 32 is connected to the air outlet of the fan 31 , and the other end is connected to the interior of the cabin 2 .

[0035] An air purification filter 4 is installed on the cabin body 2 , and a purification port located outside the cabin body 2 and an air inlet located inside the cabin body 2 are installed on the air purification filter 4 .

[0036] The air purification filter 4 is composed of a primary filter unit 43, a medium filter unit 44, a high efficiency filter unit 45 and an activated carbon filter unit 46, which are arranged in sequence along the direction of air flow from the purification port to the air inlet.

[0037] In this embodiment, the primary filter unit 43 is a plurality of nylon filter meshes arranged side by side, with nylon mesh as the filter material, and the outer frame material is various, such as plastic, aluminum alloy, etc.; the medium-efficiency filter unit 44 is a bag-type medium-efficiency bag filter, including a metal frame or a cardboard frame, and a filter bag with synthetic fiber filter material sewn inside; the high-efficiency filter unit 45 is a high-efficiency filter with a partition, using special glass fiber paper as the filter material, and separating the filter paper with special aluminum foil or paper spacers; the activated carbon filter unit 46 includes an outer shell, an activated carbon adsorption layer and a supporting structure. The outer shell is mostly made of metal or plastic material, the activated carbon adsorption layer is composed of granular or fibrous activated carbon, and the supporting structure is located below the activated carbon adsorption layer.

[0038] An illumination lamp is arranged on the top surface of the interior of the cabin 2, and an illumination switch electrically connected to the illumination lamp is arranged inside the cabin 2.

[0039] An intercom 51 and an emergency call button 52 are arranged on the inner wall of the cabin 2 , and an alarm 11 electrically connected to the emergency call button 52 is installed outside the granary 1 .

[0040] A storage rack is provided in the cabin 2, on which emergency medicines 53 and emergency oxygen cylinders 54 are placed to cope with possible injuries to personnel.

[0041] The quick-opening door is composed of two door curtain bodies 21 , which are symmetrically arranged, and the adjacent side edges of the two door curtain bodies 21 are magnetically connected.

[0042] The top edge and the side edges away from the door curtain body 21 are fixedly mounted on the cabin body 2 , and the bottom edge of the door curtain body 21 is magnetically connected to the cabin body 2 .

[0043] An infrared sensor 55 for sensing the entry and exit of personnel is provided near the quick-opening door in the cabin 2 , and the infrared sensor 55 is electrically connected to the fan 31 .

[0044] A rechargeable lithium battery pack is installed on the cabin 2 to supply power to the alarm 11, the fan 31, the intercom 51, the emergency call button 52 and the infrared sensor.

[0045] When multiple operators conduct inspections in the gas-controlled grain silo 1, they are usually divided into two groups, one group enters the grain silo 1, and the other group is outside the grain silo 1. The multiple operators entering the grain silo 1 need to wear protective clothing and oxygen supply equipment.

[0046] When an operator entering the granary 1 encounters an emergency (such as damage to the oxygen supply equipment), the operator accompanying him can lead the people in distress into the cabin 2; when passing through the quick-open door, multiple operators can pass through directly, and after the operators pass through, the two door curtain bodies 21 are quickly closed and sealed by the magnetic structure, the infrared sensor 55 sends a signal, the fan 31 is started, and filtered air is filled into the cabin 2, providing safety control and a suitable air environment for the people inside the cabin 2.

[0047] The companions can communicate with outsiders through the intercom 51 to communicate the situation in the cabin, or directly press the emergency call button 52, and the alarm 11 outside the granary 1 starts the alarm mode.

[0048] The outside rescue personnel adjust the environment in the controlled atmosphere granary 1 to the normal outside environment. The rescue personnel can enter the granary 1 without wearing any equipment, quickly open the quick-opening door and enter the cabin 2 to rescue the people in distress.

[0049] Example 2

[0050] like Figure 6-Figure 8 As shown, in this embodiment, a winch 61 is installed on the outside of the granary 1, and a steel wire rope 62 is wound on the winch 61. A plurality of lifting rings 22 are installed on the top of the cabin 2, and the plurality of lifting rings 22 are connected to a connecting seat 65. The steel wire rope 62 on the winch 61 extends into the granary 1 and is connected to the connecting seat 65. The winch 61 is wound and released to adjust the height of the cabin 2.

[0051] The granary 1 is also provided with a bracket 64, on which a guide wheel 63 is provided. The wire rope 62 of the winch 61 passes over the guide wheel 63 and extends into the granary 1 to be connected with the cabin 2. The guide wheel 63 is provided to ensure that the cabin 2 can be lifted and lowered vertically.

[0052] The top surface of the cabin body 2 is provided with a transparent observation window 23, which is convenient for outside personnel to observe the situation inside the cabin.

[0053] The connection seat 65 is located directly above the observation window 23 . A camera 66 with a wireless transmission function is disposed at the bottom of the connection seat 65 . The camera 66 is wirelessly connected to the background monitoring device.

[0054] Rescue personnel can remotely adjust the angle and focal length of the camera 66 by operating the control device in the monitoring room, so as to comprehensively and carefully observe the status of the personnel in the accommodation cabin, whether there are any items that need assistance in taking, and other specific situations.

[0055] An extension plate 24 is installed on the side of the cabin body 2. The outer side surface of the extension plate 24 is arc-shaped, and an arc-shaped chamfer transition is formed between the top surface of the extension plate 24 and the side wall of the cabin body 2.

[0056] When grains settle, they will generate squeezing force and downward pulling force on the surrounding areas. The contact between the curved bottom surface and grains is different from that between the curved bottom surface and the flat bottom surface, which can disperse the force generated by the grains during the settlement process along the curved surface. For example, when grains settle in a certain place and cause a local gap, the force exerted on the cabin 2 by the surrounding grains in the process of filling the gap will be guided to a larger area by the curved bottom surface, avoiding the appearance of concentrated force points, thereby reducing the risk of tilting or displacement of the cabin 2 caused by uneven grain settlement.

[0057] When the grain settles, the curved bottom surface can adapt to this change to a certain extent, reducing the direct effect of the impact force caused by the rapid settlement of the grain on the cabin 2. This helps to maintain the relative stability of the cabin 2 and prevent the cabin 2 from shaking or even being damaged due to the settlement of the grain.

[0058] The bottom surface of the cabin 2 and the bottom surface of the extension plate 24 are both provided with anti-slip bumps to increase the friction between the bottom surface and the grain and reduce the sliding of the cabin 2 on the grain surface; the flexible buffer pad can provide better buffering and shock absorption effect when the grain settles and generates impact, further protecting the cabin 2.

[0059] An air pressure sensor 57, an oxygen content sensor 58 and an exhaust port 59 are also provided in the cabin 2. An exhaust pipe extending to the outside of the granary 1 is provided at the exhaust port 59, and an exhaust valve is provided on the exhaust pipe.

[0060] In the present embodiment, the gas pipeline 32 and the exhaust pipe are both telescopic bellows, which have a certain telescopic range and can be telescopically adjusted during the lifting and lowering of the cabin body 2.

[0061] The air pressure sensor 57 is electrically connected to the exhaust valve and the fan 31 respectively, and the oxygen content is electrically connected to the fan 31 .

[0062] A display screen 56 is also provided in the cabin 2 . The display screen 56 is electrically connected to the air pressure sensor 57 and the oxygen content sensor 58 . The display screen 56 displays the air pressure value and the oxygen content value in the cabin 2 .

[0063] When the air pressure sensor 57 and the oxygen content sensor 58 detect that the air pressure in the cabin 2 is too low and the oxygen content is too low, the fan 31 is started to inject air into the cabin 2; when the air pressure sensor 57 and the oxygen content sensor 58 detect that the air pressure in the cabin 2 is too high and the oxygen content is too low, the fan 31 is first closed and the exhaust valve is started to exhaust the air in the cabin 2 to the outside, and then the exhaust valve is closed and the fan 31 is started to inject air into the cabin 2. The air environment in the cabin 2 is adaptively adjusted by the air pressure sensor 57, the oxygen content sensor 58, the exhaust port 59 and the air supply mechanism to provide an adaptive air environment for people in distress.

[0064] The present invention can quickly provide a safe space for people in distress by setting up a cabin body, provide a suitable air environment for people in the cabin by setting up an air supply mechanism, and facilitate people in distress to quickly enter the cabin and rescue personnel to open the cabin door in an emergency by setting up a quick-opening door, thereby greatly improving the survival rate of people in distress, ensuring the basic survival needs of people in the cabin and contact with the outside world, and improving rescue efficiency.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
