Description

Technical Field

[0001] The invention relates to the technical field of hydrogen purification, and in particular to a hydrogen purification device with an explosion-proof mechanism. Background Art

[0002] It is a device used to remove impurities from hydrogen, mainly used for the demand for high-purity hydrogen in industrial production. Through the purification device, impurities such as moisture, oxygen, hydrogen sulfide, etc. in hydrogen can be removed to obtain high-purity hydrogen. Hydrogen purification devices are widely used in many fields, including: electronics industry, metallurgy industry, machinery industry, powder metallurgy industry and glass industry. Through these applications, hydrogen purification devices play an important role in various industrial fields and ensure the supply of high-purity hydrogen.

[0003] During the use of the hydrogen purification device in the prior art, after the hydrogen purification device is heated during operation, the pipe joint gasket will easily cause hydrogen leakage due to thermal expansion and contraction. Since hydrogen is a highly flammable gas, its explosion limit range is relatively wide and its explosion energy is large. Once it accumulates to a certain concentration in a confined space, it may cause an explosion when encountering an ignition source. Therefore, the hydrogen purification device must take relevant explosion-proof measures when handling hydrogen to ensure production safety. However, the hydrogen purification device in the prior art only has relevant explosion-proof or automatic alarm mechanisms set within its working area, and no relevant mechanisms are set at the hydrogen inlet and outlet joints of the hydrogen purification device. It is impossible to monitor and handle the hydrogen leakage generated by the inlet and outlet joints in the first time, and thus it is impossible to effectively protect the explosion risk of the hydrogen purification device. Summary of the invention

[0035] As a technical optimization solution of the present invention, the blocking mechanism includes a movable sleeve 12 arranged outside the air outlet 5 and the air inlet 9, and multiple electric telescopic rods 13 are installed on the outer walls of both sides of the device body 1, and the telescopic ends of the multiple electric telescopic rods 13 are connected to the movable sleeves 12 close to them. During the telescopic process, the telescopic ends of the multiple electric telescopic rods 13 can respectively drive the two movable sleeves 12 to move and adjust on the surface of the air outlet 5 and the air inlet 9.

[0036] As a technical optimization solution of the present invention, the inner walls of the two movable sleeves 12 are provided with grooves, the insides of the two grooves are provided with air bags 15, and the outer walls of the two movable sleeves 12 are provided with first connection ends 14 for connecting to external preset air pipes. During the use of the device body 1, the external air outlet pipe and air inlet pipe are respectively connected to the air outlet end 5 and the air inlet end 9. If there is a leak at the air outlet end 5 and the air inlet end 9, the telescopic ends of the multiple electric telescopic rods 13 can be controlled to drive the corresponding movable sleeves 12 to move to the position where the leak occurs, and the external preset inflation device can be controlled to transport the gas to the inside of the air bag 15 through the air pipe, so that after the air bag 15 is inflated, it squeezes the leaking part, which can have a temporary blocking effect on the leaking part, and prevent the air outlet end 5 and the air inlet end 9 from continuing to leak.

[0037] As a technical optimization solution of the present invention, the protection mechanism includes two first slide grooves 4 opened on the outer walls of both sides of the device body 1, and the two first slide grooves 4 are both rotatably installed with screw rods 16, and the outer walls of the two screw rods 16 are commonly threadedly installed with a moving rod 6. A plurality of first drive motors are preset inside the device body 1, and the output ends of the plurality of first drive motors are respectively connected to one end of the corresponding screw rods 16, so that the plurality of screw rods 16 can be driven to rotate inside the corresponding first slide grooves 4, so that when the two screw rods 16 rotate, they can drive a moving rod 6 to move up and down on one side of the device body 1; when the rotation speeds of the plurality of screw rods 16 are the same and the directions are the same, the two moving rods 6 can be driven to move up and down synchronously.

[0038] As a technical optimization solution of the present invention, the ends of the two moving rods 6 close to the front of the device body 1 are both rotatably mounted with a rotating rod 7, and the outer walls of the two rotating rods 7 close to each other are both provided with a second slide groove 17, and the second sliders 19 are both installed inside the two second slide grooves 17. A second driving motor is preset on the outer wall of one side of the two moving rods 6, and the output ends of the two second driving motors are respectively connected to the rotating parts of the two rotating rods 7, so as to drive the two rotating rods 7 to rotate and adjust at one end of the moving rod 6; a linear motor is preset inside the two second slide grooves 17, and the two linear motors can drive the two second sliders 19 to move and adjust inside the corresponding second slide grooves 17.

[0039] As a technical optimization solution of the present invention, a protective plate 8 is installed between two second sliders 19 for common rotation, a notch 11 is provided on the top of the device body 1 to match the end of the protective plate 8 away from the rotating part, a third slide groove 24 is provided at the bottom of the protective plate 8, and two third sliders 25 are installed inside the third slide groove 24. A third driving motor is preset inside one of the second sliders 19, and the output end of the third driving motor is connected to the rotating part of the protective plate 8, so that the protective plate 8 can be driven to rotate and adjust between the two rotating rods 7; a double-headed screw is preset inside the third slide groove 24, and the two third sliders 25 are respectively matched with the outer wall threads of the double-headed screw, and one end of the double-headed screw is connected to the preset output end of the driving device, so that the double-headed screw can be driven to rotate inside the third slide groove 24, and then the two third sliders 25 can be driven to move and adjust in the third slide groove 24 in the direction of approaching or moving away from each other.

[0040] As a technical optimization solution of the present invention, the ends of the two third sliders 25 away from the third slide slot 24 are both equipped with moving blocks 20, and the bottom ends of the two moving blocks 20 are both equipped with soft brushes 21. During the movement and adjustment process, the two third sliders 25 can also synchronously drive the two moving blocks 20 to move back and forth together.

[0041] As a technical optimization solution of the present invention, the interiors of the two moving blocks 20 are both hollow, and a plurality of atomizing nozzles 26 are installed on the outer walls of the two moving blocks 20 on one side close to the soft brush 21 .

[0042] As a technical optimization solution of the present invention, a second connection end 22 is installed on one side outer wall of the two moving blocks 20, and the two second connection ends 22 are connected to an external preset liquid spraying device through a hose. A liquid spraying device is preset outside the device body 1, and the output end of the liquid spraying device transports the detergent or water to the inside of the two moving blocks 20 through a hose, and sprays it outward through a plurality of atomizing nozzles 26.

[0043] As a technical optimization solution of the present invention, a clamping block 23 is installed at the ends of the two moving blocks 20 that are away from each other, and a clamping groove 18 that is adapted to the clamping block 23 is opened on the outer wall of the side where the two rotating rods 7 are close to each other. When the two moving blocks 20 move in the direction away from each other, the two clamping blocks 23 can be driven to be inserted into the corresponding clamping grooves 18, which has a limiting and fixing effect on the protective plate 8, preventing the protective plate 8 from continuing to rotate up and down.

[0044] In the present invention, when the user uses the device, the outlet pipe and the inlet pipe are connected to the outlet end 5 and the inlet end 9 respectively, so that the hydrogen to be purified can enter the interior of the device body 1 through the inlet pipe and the inlet end 9 for purification treatment, and the purified hydrogen can be discharged to the outside through the outlet pipe and the outlet end 5 into a preset collection container.

[0045] During the use of the device body 1, at the portion where the air outlet end 5 or the air inlet end 9 is connected to the air outlet pipe and the air inlet pipe, hydrogen leakage may easily occur due to thermal expansion and contraction of the pipe joint gasket after the device body 1 is heated during operation. At this time, after the gas alarm controller 10 near the air outlet end 5 or the air inlet end 9 detects that the surrounding hydrogen concentration exceeds a preset value, the gas alarm controller 10 emits an audible and visual alarm and links a preset relay to operate, so that it can drive the solenoid valves arranged inside the air outlet end 5 and the air inlet end 9 of the device body 1 to close, thereby preventing hydrogen from continuing to leak and causing the device body 1 to be at risk of explosion, thereby improving the protection effect of the device body 1.

[0046] Furthermore, at this time, the telescopic ends of the multiple electric telescopic rods 13 can be controlled to drive the corresponding movable sleeves 12 to move to the position where the gas leaks, and the external preset inflation device can be controlled to transport the gas to the inside of the airbag 15 through the air pipe, so that after the airbag 15 is inflated, it squeezes the leaking part, which can have a temporary blocking effect on the leaking part, avoiding continuous leakage at the outlet end 5 and the inlet end 9, and reducing the probability of explosion of the device body 1.

[0047] When the device body 1 is in normal use, the two movable sleeves 12 located at the air outlet end 5 and the air inlet end 9 can control the telescopic ends of multiple electric telescopic rods 13 to extend together, pushing the two movable sleeves 12 to move in a direction away from the device body 1, and providing auxiliary support for the air outlet pipe and the air inlet pipe, thereby avoiding the air outlet pipe and the air inlet pipe from vibrating significantly when the internal hydrogen output and input flow rates are large, thereby affecting the connection stability of the air outlet pipe and the air inlet pipe.

[0048] When there is a gas leakage problem at the gas outlet 5 or the gas inlet 9, after the leaking part is temporarily blocked by the blocking mechanism, there will still be leaked hydrogen around the device body 1. At this time, the protective plate 8 between the two second sliders 19 can be controlled to rotate downward. Figure 4 The state shown is shown, and multiple screw rods 16 are controlled to rotate to drive multiple components such as two moving rods 6 to move downward together, and the protective plate 8 which is in a downward vertical state at this time is driven to move to the specified position, and the two third sliders 25 are controlled to move in opposite directions, driving the two moving blocks 20 to move from the front of the device body 1 to both sides, and atomized water is sprayed toward both sides of the device body 1 by means of multiple atomizing nozzles 26, and the flow rate of the multiple atomizing nozzles 26 is controlled to avoid static electricity generated by too high a flow rate, so that the atomized water droplets sprayed by the multiple atomizing nozzles 26 can dilute the leaked hydrogen, avoid excessive hydrogen concentration in the room, and improve the protection effect of the device body 1.

[0049] When the device body 1 is in normal use, Figure 1-Figure 3 As shown, the two rotating rods 7 are controlled to rotate downward 90 degrees to a downward vertical state, so as to prevent the two rotating rods 7 from occupying a large space during the use of the device body 1 and affecting the use of the device body 1; then the protective plate 8 between the two second sliders 19 is controlled to rotate upward 180 degrees to an upward vertical state, and the multiple screw rods 16 are controlled to drive the two moving rods 6 and other multiple components to move upward together, thereby driving the protective plate 8 in a vertical state at this time to block and protect the control panel 2, thereby preventing other unrelated personnel from touching the control panel 2 and pressing related buttons during the use of the device body 1, affecting the normal operation of the device body 1, and indirectly reducing the risk of accidents occurring in the device body 1.

[0050] Furthermore, during the use of the device body 1, in order to prevent dust and other impurities from adhering to the surfaces of the control panel 2 and the multiple instruments 3 and affecting the subsequent use by the staff, Figure 1 and Figure 4As shown, after the control protection plate 8 is rotated downward to a vertical state, the two soft brushes 21 set at the bottom of the protection plate 8 are driven to contact the front of the device body 1. As the multiple screw rods 16 rotate forward and backward, the two moving rods 6 are driven to move up and down, and the protection plate 8 and the two soft brushes 21 are driven to move up and down synchronously on the front of the device body 1, so that the two soft brushes 21 can automatically clean dust and other impurities on the surface of the control panel 2 and multiple instruments 3, which is convenient for subsequent staff to use.

[0051] After cleaning the front of the device body 1, the external preset spray equipment can be controlled to transport the volatile disinfectant to the inside of the two moving blocks 20, and spray it on the front of the device body 1 with the help of multiple atomizing nozzles 26. As the two moving rods 6 move up and down, the multiple atomizing nozzles 26 can be driven to evenly spray the disinfectant on the front of the device body 1, which is convenient for automatic disinfection and maintenance of the front of the device body 1, and is conducive to maintaining the normal operation of the device body 1.

[0052] like Figure 1-Figure 2 As shown, when the protective plate 8 is located between the two rotating rods 7 and is in a horizontal state, when the staff debugs the device body 1 again, they control the two third sliders 25 to move in the direction away from each other, driving the card blocks 23 at the ends of the two moving blocks 20 that are away from each other to be inserted into the corresponding card slots 18, and the protective plate 8 in a horizontal state is auxiliary limited and fixed to improve the stability of the protective plate 8. The staff can place related equipment or computers on the top of the protective plate 8 for use, which is convenient for the staff to debug the device body 1, avoid the staff repeatedly bending over to pick up the equipment, and reduce the staff's fatigue in the process of debugging the device body 1.

[0053] At the same time, when the staff needs to inspect and repair the relevant equipment on the top of the device body 1, they can also repeat the above steps to ensure that the horizontal protective plate 8 is relatively stable, and then control the two moving rods 6 to drive the protective plate 8 to move downward to a lower position. The staff can stand on the top of the protective plate 8 and use multiple screw rods 16 to drive the two moving rods 6 to move slowly upward, and move upward to a higher position, which is convenient for the inspection and repair of the relevant equipment on the top of the device body 1, improves the applicability of the protective mechanism, and provides greater convenience for the staff.

[0054] During the use of the device body 1, if there is water leakage from the top, the shell of the device body 1 itself has a certain waterproof effect, but there will be gaps between the multiple instruments 3 and the control panel 2 and the device body 1, so that the water leakage from the top can easily enter the control panel 2 and the instruments 3 as well as the inside of the device body 1 through the gaps. At this time, the two second sliders 19 can be controlled to move in a direction away from the device body 1, and the protective plate 8 is driven to move to a position away from the device body 1. Then, the two moving rods 6 are controlled to move upward, and the protective plate 8 and other components are driven to move upward to a specified height. Then, the protective plate 8 is controlled to flip upward between the two second sliders 19, so that the end of the protective plate 8 away from the rotating part is in contact with the notch 11 opened at the top of the front face of the device body 1. At this time, the protective plate 8 located at the top of the front face of the device body 1 in an inclined state can block and protect the water droplets dripping from the top, so as to prevent water droplets from continuously dripping on the front face of the device body 1, so that the device body 1 and the control panel 2 and other components are at risk of water leakage and erosion, thereby further improving the protective effect of the protective plate 8 on the device body 1.

[0055] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
