The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0041] In order to solve the problem of how to keep the inside of a sealed workshop isolated from the outside atmosphere at a low cost, a sealed workshop is proposed in this application. Figure 1 Schematic diagram of the structure of the sealing workshop in the embodiment of the utility model, as shown in FIG. Figure 1 As shown, the sealed workshop may include: a sealed workshop body 1, the interior of the workshop body 1 is sealed from the outside world by a sealing structure 2 so that convection between the first preset gas in the workshop body 1 and the gas outside is prevented; the sealing structure 2 includes a U-shaped channel 21, one end of the channel 21 is connected to the interior of the workshop, and the other end of the channel 21 is connected to the outside world, and the U-shaped channel 21 contains a liquid 3 that isolates the interior of the workshop body from the outside world.

[0042] The workshop body 1 in the present application is sealed from the outside by a sealing structure 2 having a channel 21 for liquid 3 so that the gas inside the workshop body 1 and the gas outside cannot convect, and the two can always be kept isolated. This sealing structure 2 not only has the advantages of low cost, good sealing effect, and a large sealing range, but also can take into account the transportation of materials 12 products 13 between the workshop body 1 and the outside. During this transportation, the gas inside the workshop body 1 will not convect with the gas outside, which can have a huge advantage of low energy consumption.

[0043] Among them, the workshop body 1 can be used to produce and process products 13 that react with certain gases or to carry out some production processes that cannot be exposed to certain gases, for example, these gases can be oxidizing gases. The interior of the workshop can be sealed with the outside atmosphere through the sealing structure 2 so that the gas in the workshop body 1 and the outside gas cannot convect, so that the outside gas cannot enter the workshop body 1, and the workshop body 1 can be filled with the gas required for its own processing and production to ensure the continuity of production and processing in the workshop body 1. As feasible, when the workshop body 1 can be used to produce and process products 13 that react with oxidizing gases or to carry out some production processes that cannot be exposed to oxidizing gases, the workshop body is filled with a first preset gas, and the first preset gas can be some non-oxidizing gases. Specifically, the first preset gas filled in the workshop body 1 can be a non-oxidizing gas such as an inert gas, nitrogen, carbon dioxide, etc., of course, the cost, safety and other factors of the gas must also be considered at the same time, so generally inert gases, nitrogen or, carbon dioxide, or a mixture of the above gases are selected.

[0044] Since there is no oxidizing gas in the workshop body 1, unmanned fully automatic equipment can be used for production and processing in the workshop body 1. In other feasible implementations, remotely operated mechanical equipment can be used for production and processing in the workshop body 1. The operator can remotely control the production and processing equipment or maintenance equipment in the workshop body 1 in the control room 11 outside the workshop body 1 in conjunction with the video monitoring equipment installed in the workshop body 1, thereby ensuring the smooth progress of production and processing in the workshop body 1. In this way, possible combustion, explosion, poisoning, oxidative corrosion, and safety accidents involving human contact and environmental leakage can be prevented.

[0045] The sealing structure 2 may include a U-shaped channel 21, the opening of which faces upward. Of course, the U-shaped channel 21 may be approximately U-shaped, for example, an arc shape is also approximately U-shaped. The sealing structure 2 may be located at the lower end of the side wall of the workshop body 1. One end of the channel 21 is connected to the interior of the workshop, and the other end of the channel 21 is connected to the outside world. In order to seal the channel 21, a liquid 3 is provided in the channel 21 so that the gas inside the workshop and the outside world cannot be connected and convected, and the interior of the workshop body 1 is isolated from the outside world, thereby ensuring that the workshop body 1 is always filled with the gas required for processing and production, and the outside oxygen or the gas in the buffer workshop 10 cannot enter the workshop body 1. The above-mentioned sealing structure 2 has the advantages of low cost, good sealing effect and large sealing range. The interior of the workshop body 1 can be sealed from the outside world through the multi-stage sealing structure 2, thereby ensuring the reliability of the sealing between the interior of the workshop body 1 and the outside world.

[0046] In order to prevent external gas from actively flowing into the workshop body 1, the pressure in the workshop can be kept greater than or equal to the pressure of the external gas, for example, the pressure in the workshop can be slightly greater than the pressure of the external gas, that is, the atmospheric pressure. In this way, it is possible to prevent the workshop body 1 from leaking into the external oxygen or other oxidizing gases due to negative pressure.

[0047] Generally speaking, the liquid 3 can be selected as water, which has the advantage of low cost. In fact, the liquid 3 can be replenished at any time when needed.

[0048] When in some special working conditions, for example, when the workshop body 1 is producing and processing products 13 that react with water or performing some production processes that cannot be exposed to water, the liquid 3 can be selected from other liquids with low volatility, which can reduce the volatility of the liquid 3 and reduce the amount of liquid 3 replenished to the channel 21 as much as possible; secondly, the concentration of the liquid 3 substance in the first preset gas in the workshop body 1 can be greatly reduced to avoid its precipitation. The low-volatility liquid can be alkane oils such as kerosene and diesel, or it can be a low-temperature resistant antifreeze solvent.

[0049] In the present application, the sealing structure 2 can not only be used to achieve the sealing of the interior of the workshop body 1 with the outside world so that the first preset gas in the workshop body 1 cannot convect with the outside gas, but also can be used to transport materials 12, products 13 and tool parts in and out of the workshop body 1. The sealed workshop may include: a transport box 4. The transport box 4 can be opened to put materials 12 or products 13 or tool parts into the transport box 4 or take out materials 12 or products 13 from the transport box 4. When the transport box 4 is in a closed state, the interior of the transport box 4 is kept sealed from the outside world. As feasible, the transport box 4 can have a gas inlet and outlet interface that can be opened and closed, and the gas inlet and outlet interface can be opened and sealed to extract the gas in the transport box 4 and fill it with the first preset gas, thereby ensuring that the transport box 4 cannot bring an unacceptable dose of oxidizing gas into the workshop. When it is necessary to transport the material 12 into the workshop body 1, the material 12 is loaded into the transport box 4, and the oxidizing gas in the transport box 4 is discharged through the gas inlet and outlet interface of the transport box 4, so that the transport box 4 is filled with non-oxidizing gas, for example, the first preset gas. Afterwards, the transport box 4 is transported between the workshop body 1 and the outside through the channel 21 and through the liquid 3. When the processed product 13 needs to be transported out of the workshop body 1, a similar method as described above can also be used.

[0050] In other feasible embodiments, the transport box 4 may contain materials capable of absorbing or consuming oxidizing gases, thereby ensuring that the transport box 4 cannot bring unacceptable amounts of oxidizing gases into the workshop. The type of material corresponds to the specific oxidizing gas.

[0051] When the transport box 4 passes through the channel 21 and through the liquid 3 to be transported between the workshop body 1 and the outside world, the liquid 3 can not only allow the transport box 4 to pass through the channel 21, but also keep the inside of the workshop body 1 sealed from the outside world. Compared with the prior art, after opening the sealing valve, the inside of the workshop body 1 needs to be evacuated again and the first preset gas needs to be added. This method requires a lot of time and requires additional costs. In addition, the sealing valve needs to remain sealed, and its own cost is also very high, and the maintenance cost is also high during repeated use. Finally, in the prior art, the pressure inside the workshop body 1 will change with the change of temperature by using the sealing valve method, which makes the pressure load of the workshop body 1 have higher requirements. However, since the present application adopts a liquid-sealed sealing structure 2, it can automatically compensate for the pressure difference between the inside of the workshop body 1 and the outside world, and there is no need to worry about the problem of too high or too low pressure in the workshop body 1.

[0052] Of course, the transport box 4 can also be used to transport the materials 12 or products 13 that have been processed in the workshop body 1 out of the workshop body 1 through the passage 21 to the outside in the same manner.

[0053] In a feasible embodiment, the lower end surface of the U-shaped channel 21 can be in an arc shape with a small slope, so that a power device and wheels driven by the power device can be installed on the transport box 4, so that the transport box 4 can actively walk into the channel 21 and reach the other end of the channel 21 after passing through the liquid 3. In other feasible embodiments, a conveying mechanism extending along the extension direction of the channel 21 can also be installed in the channel 21, and the conveying mechanism can actively move along the extension direction of the channel 21 to transport the transport box 4 installed on the conveying mechanism from one end of the channel 21 to the other end. For example, the conveying mechanism can include a track extending along the extension direction of the channel 21, and a driven chain installed on the track. The chain can be in a closed loop, one end of the chain extends to one end of the channel 21, and the other end of the chain extends to the other end of the channel 21. The chain is continuously rotated, so as to transport the transport box 4 installed on the chain from one end of the channel 21 to the other end, and the track can be used to limit or support the transport box 4.

[0054] In order to control the temperature in the workshop body 1, as a feasible method, the sealed workshop may include: a cooling system with a heat exchange function arranged in the workshop body. For example, the cooling system includes: a first spray mechanism 5 installed in the workshop body 1. The first spray mechanism 5 may include: a first spray component that can disperse and spray the liquid; a first collection component 6 for receiving and collecting the liquid sprayed by the spray component. After the liquid is dispersed and sprayed, it can fully exchange heat with the first preset gas in the workshop body 1 to absorb the heat generated during the production process in the workshop body 1 and reduce the temperature of the first preset gas in the workshop body 1. When the liquid 3 is the same as the liquid in the channel 21, the first collection component 6 is used to discharge the collected liquid into the channel 21, so as to recycle the sprayed liquid. Further, the inlet of the first spray mechanism 5 can be connected to the liquid in the channel 21, so as to suck out the liquid in the channel 21 for dispersed spraying, so that the liquid in the channel 21 that plays a sealing role can be recycled.

[0055] When the liquid in the channel 21 is continuously used to cool down the workshop body 1, the temperature of the liquid in the channel 21 will rise. In order to ensure the effect of using the liquid in the channel 21 to cool down the workshop body 1, the sealed workshop may include: a second spray mechanism 7 installed outside the workshop body 1. The second spray mechanism 7 may include: a second spray component that can disperse and spray the liquid, the inlet of the second spray component is connected to the channel 21; a second collection component 8 for receiving and collecting the liquid sprayed by the spray component, and the second collection component 8 is used to discharge the collected liquid into the channel 21. The second spray mechanism 7 sucks out the liquid in the channel 21 for dispersed spraying, and exchanges heat with the outside air, so that the dispersed sprayed liquid is greatly cooled. The cooled liquid is collected by the second collection component 8 and discharged into the channel 21. In this cycle, the liquid in the channel 21 can achieve the purpose of cooling.

[0056] As a feasible method, the sealed workshop may include: a gas generating device 9 arranged outside the workshop body 1. The gas generating device 9 is capable of replenishing the first preset gas into the workshop body 1. The gas generating device 9 may store the first preset gas to replenish the first preset gas into the workshop body 1. The gas generating device 9 may also separate the first preset gas from the external air and replenish the first preset gas into the workshop body 1. An air pressure detection device may be arranged in the workshop body 1, and the air pressure detection device is used to detect the pressure of the first preset gas in the workshop body 1. When the pressure of the first preset gas is lower than the preset value, the gas generating device 9 may start to replenish the first preset gas into the workshop body 1.

[0057] As a feasible method, the oxygen-free workshop may include: an air pressure and air temperature balance control system. The air pressure and air temperature balance control system may control the air pressure balance between the workshop body and the outside world by heating and cooling the temperature of the first preset gas in the workshop body 1. The air pressure and air temperature balance control system may also replenish the gas in the workshop body 1 or release the gas in the workshop body 1 through air pressure detection to ensure the air pressure balance between the workshop body 1 and the outside world. For example, the air pressure and air temperature balance control system may include a gas generating device 9 and a gas releasing device, and the gas releasing device is used to release the gas in the workshop body 1. The air pressure and air temperature balance control system may also include an air pressure detection device, which controls the gas generating device 9 and the gas releasing device according to the pressure of the first preset gas in the workshop body 1 detected by the air pressure detection device, or controls the heating and cooling of the temperature of the first preset gas.

[0058] The sealed workshop may include: a first oxidizing gas removal device, which is used to remove the oxidizing gas in the workshop body 1. Generally speaking, the first oxidizing gas removal device is arranged in the workshop body 1. The first oxidizing gas removal device can ensure that the oxidizing gas contained in the gas in the workshop body 1 is lower than the preset concentration value. For example, the first oxidizing gas removal device can be a pressure swing adsorption oxygen separation device, a molecular sieve membrane oxygen separation device, etc., or a catalyst material carrying precious metals such as palladium and platinum, an oxygen absorbing material with a sacrificial reducing agent such as iron powder, aluminum powder, carbon powder, etc.

[0059] The sealed workshop may include: a first oxidizing gas concentration detection device disposed in the workshop body 1, which is used to detect the concentration of the oxidizing gas in the workshop body 1. When the concentration of the oxidizing gas in the workshop body 1 detected by the first oxidizing gas concentration detection device exceeds the standard, the oxidizing gas in the workshop body 1 is removed by the first oxidizing gas removal device.

[0060] The sealed workshop may include: a buffer workshop 10. The buffer workshop 10 is sealed with the workshop body 1 through a sealing structure 2 so that the first preset gas in the workshop body 1 and the gas in the buffer workshop 10 cannot convect. The buffer workshop 10 is sealed with the outside world through a sealing structure 2 so that the gas in the buffer workshop 10 and the gas outside cannot convect. The buffer workshop 10 can ensure that the oxidizing gas does not enter the workshop body 1 during the process of materials 12 and products 13 entering and leaving the workshop body 1.

[0061] The sealed workshop may include: a second oxidizing gas removal device, which is used to remove the oxidizing gas in the buffer workshop 10. Generally speaking, the second oxidizing gas removal device is arranged in the buffer workshop 10. The second oxidizing gas removal device is used to remove the oxidizing gas in the buffer workshop 10.

[0062] The external materials 12 can be first transported to the buffer workshop 10 for storage through the transport box 4. When the materials 12 are needed for processing in the workshop body 1, the materials 12 in the buffer workshop 10 are transported to the workshop body 1 through the transport box 4. The materials 12 can be taken out of the transport box 4 in the buffer workshop 10, so that the oxidizing gas remaining in the materials 12 or the transport box 4 is released in the buffer workshop 10, and these oxidizing gases can be removed by the second oxidizing gas removal device. When the materials 12 in the buffer workshop 10 are transported to the workshop body 1 through the transport box 4, the transport box 4 and the materials 12 will basically not carry any oxidizing gas into the workshop body 1.

[0063] The sealed workshop may include: a second oxidizing gas concentration detection device disposed in the buffer workshop 10, which is used to detect the concentration of the oxidizing gas in the buffer workshop 10. When the concentration of the oxidizing gas in the buffer workshop 10 detected by the second oxidizing gas concentration detection device exceeds the standard, the oxidizing gas in the buffer workshop 10 is removed by the second oxidizing gas removal device.

[0064] In a feasible implementation, a plurality of sealed workshops may cooperate with each other to form a connection in the process of processing a certain product 13, thereby forming an anaerobic production system to process or generate a product 13 with complex processing steps.
