The technical problem is that part of gas and staff leave a workshop together, so that part of gas enters a non-leakage area. According to the technical scheme, the protective airtight door comprises a door frame, an electric sliding door and the like. The two sides of the door frame are each slidably connected with an electric sliding door. After pure gas enters the gas spraying holes, a gas curtain is formed between the two electric sliding doors, so that when workers leave from the two electric sliding doors, the gas curtain plays a role in isolation, chemical gas is prevented from drifting away, meanwhile, due to the fact that the gas spraying holes are inclined, the pure gas can blow the gas drifting to the positions beside the electric sliding doors to the interior of a workshop, and the safety of the workers is improved. Therefore, gas is prevented from floating away from the electric sliding door, and chemical gas can be isolated from leaving from a workshop together with staff while the staff are evacuated.

Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to a protective closed door. Background Art

[0002] During the chemical production process, gas leakage may occur. To ensure the safety of employees, there are usually safe passages for employees to evacuate. After evacuation, the sealed doors are closed to isolate the gas, thereby preventing more leaked gas from entering the workshop or other areas from the leak source, thereby avoiding the leakage from worsening and the increase of leakage risk;

[0003] However, the existing sealed doors can only be closed after all employees have evacuated. During the evacuation period, some gas will leave the workshop with the employees, causing some gas to enter the non-leaking area, thereby expanding the leakage area and easily causing employees in the non-leaking area to inhale part of the gas, thus affecting their life safety. Utility Model Content

[0004] In order to overcome the disadvantage that part of the gas will leave the workshop together with the employees, thereby causing part of the gas to enter the non-leaking area, the utility model provides a protective airtight door.

[0005] The technical solution of the utility model is: a protective closed door, comprising a door frame and an electric sliding door; an electric sliding door is slidably connected to each of the two sides of the door frame; the electric sliding door is connected to an external power supply; it also comprises an electric roller and an air jet plate; each electric sliding door is rotatably connected to an electric roller, and the electric roller is connected to the external power supply; each electric roller is fixedly connected to a air jet plate; the air jet plate is provided with an air inlet hole; the air jet plate is provided with at least three connecting holes; each connecting hole of the air jet plate is provided with a plurality of air jet holes.

[0006] As a preferred technical solution of the utility model, the air jet hole is inclined.

[0007] As a preferred technical solution of the utility model, the closer the air jet hole is to the middle of the door frame, the larger the inclination angle is.

[0008] As a preferred technical solution of the utility model, the jet plate is provided with a water inlet hole; the water inlet hole is communicated with the communication hole closest to the middle of the door frame.

[0009] As a preferred technical solution of the utility model, it also includes an airbag; the airbag is fixedly connected to the left side of the right electric sliding door; the right electric sliding door is provided with a plurality of two ventilation holes; all the ventilation holes are connected to the airbag; and a groove is provided on the right side of the left electric sliding door.

[0010] As a preferred technical solution of the present utility model, the groove of the electric sliding door is made of silicone material.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] When pure gas passes through the jet hole, an air curtain will be formed between the two electric sliding doors. When employees evacuate from the two electric sliding doors, the air curtain will act as an isolation to prevent chemical gases from drifting away. At the same time, since the jet hole is inclined, pure gas will blow the gas that drifts to the electric sliding door into the workshop, thereby preventing the gas from drifting away from the electric sliding door. This allows employees to evacuate while isolating chemical gases from leaving the workshop together with the employees.

[0013] When employees pass through the water curtain, water falls on them and stays on them for a long time, which dilutes the attached chemical gases, thereby reducing the harmfulness of the chemical gases and making the chemical gases, which were originally only slightly harmful, even smaller, so that they will not cause harm to the human body, thereby protecting the personal safety of employees. At the same time, after the water curtain is sprayed out, it can also dilute the chemical gases in the workshop, thereby speeding up the cleaning of leaked chemical gases.

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0020] Example 1

[0021] A protective closed door, such as Figure 1-4 As shown, it includes a door frame 1 and an electric sliding door 2; the left and right sides of the door frame 1 are each slidably connected with an electric sliding door 2; the electric sliding door 2 is connected to an external power supply;

[0022] It also includes an electric roller 3 and a jet plate 4; each electric sliding door 2 is rotatably connected to an electric roller 3, and the electric roller 3 is connected to an external power supply; each electric roller 3 is fixedly connected to a jet plate 4; the jet plate 4 is provided with an air inlet 4a; the jet plate 4 is provided with three connecting holes 4b; each connecting hole 4b of the jet plate 4 has nine jet holes 4c.

[0023] The air jet hole 4 c is inclined, and blows the gas floating to the electric sliding door 2 toward the inside of the workshop, thereby preventing the gas from floating away from the electric sliding door 2 .

[0024] The closer the jet hole 4c is to the middle of the door frame 1, the greater the inclination angle is, so that the interval between each air curtain is increased, thereby preventing two employees from being too close to each other from blocking all the gas ejected from the jet hole 4c and causing gas leakage.

[0025] The jet plate 4 has a water inlet hole 4d, which is connected to the communication hole 4b closest to the middle of the door frame 1, and the jet hole 4c sprays water through the water inlet hole 4d, thereby reducing and diluting the gas attached to the employee.

[0026] It also includes an airbag 111; the airbag 111 is fixedly connected to the left side of the right electric sliding door 2; the right electric sliding door 2 is provided with two vents 2a; all the vents 2a are connected to the airbag 111; the right side of the left electric sliding door 2 is provided with a groove 2b.

[0027] The groove 2 b of the electric sliding door 2 is made of silicone material, thereby enhancing the airtightness between the airbag 111 and the electric sliding door 2 .

[0028] The specific working steps are:

[0029] The air vent 2a and the air inlet 4a are respectively connected to an external air supply device, and the water inlet 4d is connected to an external water supply device;

[0030] When chemical gas leakage occurs, the two electric sliding doors 2 are driven to move toward opposite sides, and the movement is stopped when the distance between the two electric sliding doors 2 allows employees to enter and exit freely, such as Figure 2 The state shown, and then the electric roller 3 drives the jet plate 4 to rotate, so that the jet plate 4 is perpendicular to the electric sliding door 2, as shown in FIG. Figure 2In the state shown, the external air supply equipment will then deliver pure gas to the air inlet 4a, so that the pure gas enters the three connecting holes 4b, and then is ejected from the jet hole 4c. When the pure gas is ejected from the jet hole 4c, an air curtain will be formed between the two electric sliding doors 2, so that when the employees evacuate from the two electric sliding doors 2, the air curtain plays an isolating role to prevent the chemical gas from drifting away. At the same time, since the jet hole 4c is inclined, the pure gas will blow the gas that drifts to the side of the electric sliding door 2 into the interior of the workshop, thereby preventing the gas from drifting away from the electric sliding door 2, so that the chemical gas can be isolated from the employees when they evacuate from the workshop;

[0031] However, when chemical gas leaks, it will adhere to the employees, and the employees evacuate quickly and have a short contact time with pure gas, resulting in the pure gas being unable to completely blow away the attached gas. As a result, after the employees evacuate, they will still inhale chemical gas, which will affect their life safety. Therefore, while the external air supply device delivers pure gas, the external water supply device will deliver water to the water inlet hole 4d, so that the water enters the connecting hole 4b closest to the middle of the door frame 1 through the water inlet hole 4d, and then sprays out from the jet hole 4c closest to the middle of the door frame 1 together with the pure gas, thereby forming a water curtain. When employees pass through the water curtain, water falls on them, and the water will stay on them for a long time, so that the water can dilute the attached chemical gas, thereby reducing the harmfulness of the chemical gas, thus protecting the personal safety of the employees. At the same time, after the water curtain is sprayed, it can also dilute the chemical gas in the workshop, thereby speeding up the cleaning speed of the leaked chemical gas; when the employees have evacuated, the two electric sliding doors 2 are controlled to move toward each other again, so that the two are in contact with each other, thereby sealing, and then isolating the chemical gas from leaking from the workshop to other areas, and then the peripheral air supply and water supply equipment can be turned off;

[0032] Generally, in order to ensure the airtightness of the two electric sliding doors 2 after they are in contact, sealing strips are provided on the opposite sides of the two electric sliding doors 2 to enhance the airtightness. However, the sealing strips will be deformed after long-term use. When deformation occurs and gaps appear, chemical gases will leak. Therefore, when the two electric sliding doors 2 are sealed, an external air supply device will supply air to the vent 2a, so that the gas enters the airbag 111 through the vent 2a, causing the airbag 111 to expand. When the airbag 111 expands, the airbag 111 will enter the groove 2b, thereby expanding into a state of fitting the groove 2b, thereby enhancing the airtightness of the electric sliding doors 2 after they are in contact with each other.

[0033] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
