Description

Technical Field

[0001] The utility model relates to the field of agricultural storage, in particular to an emergency isolation cabin for a controlled atmosphere warehouse. Background Art

[0002] With the development of agricultural production technology, grain production continues to increase. Controlled atmosphere emergency isolation chambers, as important units of grain storage, currently serve only as storage spaces for accumulated grain. The status, inventory, and storage management of the grain contained within these emergency isolation chambers remain largely under human control, requiring the chamber door to be opened to inspect the grain's condition. Because these emergency isolation chambers are sealed using controlled atmosphere storage technology, they require an ultra-low oxygen controlled atmosphere (oxygen content ≤ 1%) and high nitrogen (nitrogen content ≥ 99%) to effectively control the growth of pests and mold and reduce grain quality losses.

[0003] However, existing controlled atmosphere emergency isolation chamber doors are typically sealed doors. This can lead to significant nitrogen loss during procedures such as opening the door for grain inspection. Furthermore, the door lock requires a strong seal, making opening and closing the door cumbersome and labor-intensive, making it inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a controlled atmosphere emergency isolation cabin, aiming to improve the problem that the sealing door of the existing controlled atmosphere emergency isolation cabin is relatively cumbersome to use.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a controlled atmosphere emergency isolation chamber, comprising:

[0006] A controlled atmosphere chamber, wherein a sealed door is provided on the side of the top thereof, the sealed door comprising a door frame provided on the side of the controlled atmosphere chamber, a door panel sealed on the door frame, and a magnetic unit, the magnetic unit comprising at least one electromagnetic component provided on the door frame, a magnetic component connected to the electromagnetic component provided on the door panel, a mechanical lock provided on the door panel, and a lock slot provided on the door frame for inserting and locking with or separating from a latch of the mechanical lock; and

[0007] The isolation room is connected to the sealed door, and a ladder is provided at the entrance of the isolation room; a blower is provided at the top of the isolation room.

[0008] Preferably, the edge of the door panel is provided with a sealing baffle which abuts against the end face of the door frame for sealing, or the edge of the door frame is provided with a contour baffle which abuts against the door panel for sealing.

[0009] Preferably, a sealing gasket is provided on the contact surface between the sealing baffle and the door frame, or a sealing gasket is provided on the contact surface between the contour baffle and the door panel.

[0010] Preferably, the door panel is further provided with an identity identifier and a controller electrically connected to an output end of the identifier, and the output end of the controller is electrically connected to the magnetic member.

[0011] Preferably, an oxygen content detector and an alarm electrically connected to the oxygen content detector are provided in the isolation chamber, the blower is electrically connected to the detector, and the oxygen content detector is communicatively connected to the controller.

[0012] Preferably, it also includes a regulating pump, a gas source tank for supplying gas to the regulating pump, and a nitrogen detector for detecting the nitrogen content in the gas-regulated warehouse. The regulating pump and the gas source tank are arranged in the isolation room, and the nitrogen detector is communicatively connected to the controller.

[0013] Preferably, the isolation chamber is further provided with a display screen electrically connected to the controller.

[0014] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0015] 1. An isolation chamber is set up at the sealed door of the controlled atmosphere chamber, forming a preparation room for entering and exiting the emergency isolation chamber (oxygen masks and other equipment are required to enter the controlled atmosphere chamber). At the same time, it can form a buffer zone to prevent the sealed door from directly connecting to the outside, preventing the rapid flow of external gas and reducing nitrogen loss within the controlled atmosphere chamber. Furthermore, the door panel uses a magnetic door structure for locking, which can be opened and closed quickly after the mechanical lock is released, ensuring smooth and convenient entry and exit, while also reducing nitrogen loss within the controlled atmosphere chamber, which has excellent practicality.

[0029] Embodiment

[0030] Please refer to Figure 1 and Figure 2As shown, the present embodiment provides an emergency isolation cabin for a controlled atmosphere warehouse, comprising a controlled atmosphere warehouse 10 and an isolation chamber 20, a sealed door 11 is provided on the side of the top of the controlled atmosphere warehouse 10, the sealed door 11 comprises a door frame 111 provided on the side of the controlled atmosphere warehouse 10, a door panel 112 sealed on the door frame 111 and a magnetic unit 113, the magnetic unit 113 comprises at least one electromagnetic component 1111 provided on the door frame 111, a magnetic component 1121 connected to the electromagnetic component 1111 is provided on the door panel 112, a mechanical lock 1122 is provided on the door panel 112, and a lock slot for locking or separating the latch of the mechanical lock 1122 is provided on the door frame 111; the isolation chamber 20 is connected to the sealed door 11, and a ladder 201 is provided at the entrance of the isolation chamber 20; a blower 202 is provided on the top of the isolation chamber 20.

[0031] Specifically, after the grain is stored and sealed in the controlled atmosphere warehouse 10, it is necessary to carry out an ultra-low oxygen controlled atmosphere state with low oxygen (oxygen content ≤ 1%) and high nitrogen (nitrogen content ≥ 99%) in the emergency isolation cabin of the controlled atmosphere warehouse to effectively control the reproduction of pests and molds and reduce the loss of grain quality.

[0032] Furthermore, when entering and exiting the controlled atmosphere chamber 10 (an oxygen mask or other equipment is required to enter the controlled atmosphere chamber 10), the isolation chamber 20 is designed to provide a relatively small air flow environment at the sealed door 11, thereby reducing nitrogen loss within the controlled atmosphere chamber 10. At the same time, a buffer zone is formed to prevent the sealed door 11 from being directly connected to the outside, preventing the rapid flow of external air, and reducing nitrogen loss within the controlled atmosphere chamber 10.

[0033] Furthermore, the door panel 112 is locked with a magnetic door structure, which can quickly open and close after releasing the mechanical lock 1122, ensuring smooth and convenient entry and exit, while also reducing the loss of nitrogen in the gas-controlled chamber 10, and having good practicality. Specifically, an electromagnetic component 1111 (which can be a permanent magnetic door suction or a magnetic seat for electromagnetic door suction) is installed on the door frame 111, and is attracted by the electromagnetic component 1111 (magnetic clamp) on the door panel 112 using the electromagnetic principle, so that it can be opened and closed immediately, and can be sealed after being attracted, avoiding the situation where the door panel 112 is not completely closed after entry and exit, thereby improving practicality. At the same time, in order to ensure the sealing of the sealed door 11, the door panel 112 is also provided with a mechanical lock 1122 for locking to prevent the magnetic unit 113 from failing in the event of a power outage, thereby ensuring the sealing performance of the sealed door 11.

[0034] Furthermore, the isolation room 20 is designed to be a relatively sealed space. In order to ensure that there is sufficient oxygen in the isolation room 20, the air flow in the isolation room 20 will be exchanged through the blower 202 to ensure the normal use of the isolation room 20.

[0035] Furthermore, the edge of the door panel 112 is provided with a sealing baffle 1123 that abuts against the end face of the door frame 111 for sealing, or the edge of the door frame 111 is provided with a contour baffle that abuts against the door panel 112 for sealing. By designing the baffle structure at the edge of the door panel 112 or the edge of the door frame 111, an effective sealing area can be formed, so that the door panel 112 can be contact-sealed after closing, and the force required to open or close the door panel 112 can be reduced. That is, a gap can be provided between the side surface of the door panel 112 and the inner side surface of the door frame 111, eliminating the structure of the sealing ring on the side surface and improving practicality.

[0036] like Figure 2 As shown, in this embodiment, a sealing gasket 1125 is provided on the contact surface between the sealing baffle 1123 and the door frame 111, or a sealing gasket 1125 is provided on the contact surface between the contour baffle and the door panel 112. The sealing gasket 1125 can be a silicone gasket or a rubber gasket to ensure the sealing of the door panel 112 after closing.

[0037] like Figure 2 As shown, in this embodiment, the door panel 112 is also provided with an identity identifier 1124 and a controller electrically connected to the output of the identifier. The output of the controller is electrically connected to the magnetic element 1121. The identity identifier 1124 can be a fingerprint reader or a facial recognition camera, etc., so as to identify and record the identity information of people entering the controlled atmosphere chamber 10. The controller can be a 51 series single-chip microcomputer, and the magnetic element 1121 can be an electromagnetic door seat. Based on the feedback from the controller, the magnetic attraction unit 113 can be opened or closed. Only after the identity is confirmed can the person enter the controlled atmosphere chamber 10.

[0038] like Figure 1 As shown, in this embodiment, an oxygen content detector and an alarm 203 electrically connected to the oxygen content detector, such as a buzzer, are provided in the isolation chamber 20. A blower 202 is electrically connected to the detector, and the oxygen content detector is in communication with the controller. The oxygen content detector can be a ZH500-02 oxygen detector that can monitor the oxygen content in the isolation chamber 20. If the oxygen content exceeds a dangerous value, the alarm 203 can sound an alarm to remind people entering the isolation chamber 20 that the air needs to be exchanged to ensure safety within the isolation chamber 20.

[0039] like Figure 1As shown, this embodiment also includes a regulating pump 30, an air source tank 31 for supplying air to the regulating pump 30, and a nitrogen detector (not shown in the figure) for detecting the nitrogen content in the gas-controlled warehouse 10, such as a nitrogen concentration sensor with the model number HD-T700X-N2. The regulating pump 30 and the air source tank 31 are arranged in the isolation chamber 20, and the nitrogen detector is communicatively connected to the controller. The air source tank 31 can be a nitrogen tank. The nitrogen concentration in the gas-controlled warehouse 10 is known through the nitrogen detector. If it is low, the nitrogen in the air source tank 31 can be extracted by the regulating pump 30 for replenishment to ensure the nitrogen concentration in the gas-controlled warehouse 10, thereby effectively controlling the reproduction of pests and molds and reducing the loss of grain quality.

[0040] like Figure 2 As shown, in this embodiment, a display screen 204 electrically connected to the controller is further provided in the isolation chamber 20. The display screen 204 can display information such as the nitrogen and oxygen concentration values ​​in the gas-controlled chamber 10, the oxygen concentration value in the isolation chamber 20, and the personnel record sheet entering and leaving the gas-controlled chamber 10 for management personnel to view, thereby improving practicality.

[0041] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
