Description

Technical Field

[0001] The present invention relates to the technical field of new energy equipment, and in particular to a buffer filtering device for hydrogen storage equipment. Background Art

[0002] Traditional energy sources are fixed in quantity and have certain pollution. Currently, clean new energy sources are being used more and more widely. Among them, hydrogen is the most widely used. When hydrogen burns, it not only produces high energy, but also only produces water after combustion, which does not cause pollution.

[0003] In actual use, hydrogen is compressed by a hydrogen compressor and then input into the equipment. In order to prevent the high hydrogen pressure from causing impact on the equipment, a hydrogen buffer tank is often installed between the hydrogen compressor and the equipment. The current hydrogen buffer tank only has a buffering function, and the hydrogen will heat up the side wall of the hydrogen buffer tank when it is transported in the hydrogen buffer tank, causing safety hazards. In addition, the hydrogen buffer tank will vibrate after being impacted by hydrogen. Under long-term vibration, it will affect the components inside the hydrogen buffer tank, and ultimately affect the air tightness of the device.

[0018] When hydrogen enters the connecting tube, it will impact the connecting tube, and the connecting tube will vibrate at this time.

A filter plate 21 is movably installed on the side of the lifting plate 5 close to the air inlet 2. The hydrogen passes through the filter plate 21 under the action of pressure, and then the hydrogen passing through the filter plate 21 flows through the opening 31 and continues to flow toward the rear of the connecting tube 1. The way that the hydrogen passes through the filter plate 21 allows the filter plate 21 to filter the hydrogen, preventing solid particles generated during the production and compression of hydrogen from entering the hydrogen storage tank with the hydrogen, causing pollution and damage to the hydrogen storage tank, thereby increasing the ease of use of the device.

[0039] As a technical optimization solution of the present invention, the buffer mechanism includes a baffle plate 22. A plurality of baffle plates 22 are evenly arranged on the inner walls of both sides of the connecting tube 1 near the gas outlet 3. A displacement chute 25 is provided on the inner walls of both sides of the connecting tube 1 near the baffle plate 22. A displacement slider 26 is slidably installed inside the displacement chute 25. The side of the displacement slider 26 near the baffle plate 22 is connected to the baffle plate 22. The baffle plate 22 is driven to move by the movement of the displacement slider 26 in the displacement chute 25. The baffle plate 22 is moved to a preset position in the connecting tube 1, so that the hydrogen can be buffered by the channel formed by the plurality of baffle plates 22 when it circulates inside the connecting tube 1. Then, the hydrogen flows into the interior of the hydrogen storage tank through the gas outlet 3. This operation mode can reduce the impact force of the hydrogen entering the hydrogen storage tank.

[0040] As a technical optimization solution of the present invention, the connecting tube 1 is provided with first slide grooves 8 on both sides of the outer side of one end close to the air inlet 2, and a first electric slider 9 is installed at the bottom of the movable plate 6 close to the first slide groove 8, and the first electric slider 9 is slidably installed inside the first slide groove 8. The sliding of the first electric slider 9 in the first slide groove 8 can drive the movable plate 6 to move according to the use requirements.

[0041] As a technical optimization solution of the present invention, a lifting slot 15 is vertically opened on the side of the movable plate 6 away from the connecting tube 1, and a lifting slider 16 is slidably installed inside the lifting slot 15. A connecting block 14 is installed on the side of the lifting slider 16 away from the movable plate 6, and an adapter 10 is movably installed on the top of the connecting block 14, and a fan 7 is movably installed inside the adapter 10. The fan 7 is started, and the air flow outside the connecting tube 1 can be enhanced by the blowing of the fan 7. Through this operation mode, the outside of the connecting tube 1 can be cooled, so that the heat generated by the hydrogen when buffering inside the connecting tube 1 can be quickly dissipated, and the functional use stability of the device is increased.

[0042] As a technical optimization solution of the present invention, a second rotary motor 18 is embedded and installed on the top of the connecting block 14, the output end of the second rotary motor 18 is upward, and the output end of the second rotary motor 18 is connected to the bottom of the adapter 10, and the first rotary motor 17 is embedded and installed on the top and bottom inner walls of the adapter 10, the output end of the first rotary motor 17 faces the fan 7, and the output end of the first rotary motor 17 is connected to the fan 7. The first rotary motor 17 can adjust the wind direction of the fan 7, so that the fan 7 can be used under different usage requirements.

[0043] As a technical optimization solution of the present invention, the adapter 10 is vertically provided with a second chute 11 on one side close to the air inlet 2, a second electric slider 12 is slidably installed inside the second chute 11, and a cleaning brush 13 is installed on the side of the second electric slider 12 away from the adapter 10. The movement of the second electric slider 12 in the second chute 11 can drive the cleaning brush 13 to move, and the movement of the cleaning brush 13 on the outside of the filter plate 21 can self-clean the filter plate 21.

[0044] As a technical optimization solution of the present invention, the auxiliary mechanism includes a spring 20, and a second slot 19 is provided inside the movable plate 6 on a side close to the connecting cylinder 1. The two ends of the spring 20 are respectively connected to the inner walls of the two ends of the second slot 19, and silicone oil is injected into the second slot 19. The vibration of the connecting cylinder 1 will be transmitted to the movable plate 6, and the spring 20 inside the movable plate 6 will shake. Since silicone oil is injected into the second slot 19, the spring 20 will be subject to resistance from the silicone oil during the shaking process, thereby consuming kinetic energy. Through this operation mode, the shock absorption effect of the connecting cylinder 1 is achieved, and the safety of the device is increased.

[0045] When the present invention is in use, the electric drive devices used in the device are all powered by an external power supply through a wire. The device controls the electrical equipment in the device through an external control system. The air pressure sensor 27 used in the device is an existing mature technology, so it will not be elaborated on in detail. The air inlet 2 and the air outlet 3 are both controlled by an electromagnetic valve, and the connection method between the air inlet 2 and the air outlet 3 is an existing mature technology, so it will not be elaborated on in detail. The filter plate 21 used in the device is an existing mature technology, so it will not be elaborated on in detail. The positioning block 29 can be connected to the threaded groove in the positioning groove 30 by installing bolts to complete the fixed installation of the filter plate 21. By installing a sealing plate 32 on the top of the lifting plate 5, the first slot 4 can be sealed to prevent hydrogen from leaking from the first slot 4 when the device is in use. The sealing plate 32 is detachable, which is convenient for the device to replace and maintain parts.

[0046] When the device is in use, the air inlet 2 is connected to a preset hydrogen compressor outside the device, and the air outlet 3 is connected to a preset hydrogen storage tank outside the device. The solenoid valves at the air inlet 2 and the air outlet 3 are opened, and the hydrogen enters the interior of the connecting tube 1 from the air inlet 2, and then the compressed hydrogen passes through the filter plate 21. The hydrogen passes through the filter plate 21 under the action of pressure, and then the hydrogen that passes through the filter plate 21 flows through the opening 31 and continues to flow toward the rear of the connecting tube 1. The way the hydrogen passes through the filter plate 21 allows the filter plate 21 to filter the hydrogen, thereby preventing solid particles generated during the production and compression of hydrogen from entering the hydrogen storage tank with the hydrogen, causing pollution and damage to the hydrogen storage tank, thereby increasing the convenience of using the device.

[0047] Before use, the device slides the displacement slider 26 in the displacement slot 25 to move the baffle plate 22 up and down inside the connecting tube 1, and the two adjacent baffle plates 22 are adjusted to a state where one baffle plate 22 abuts against the top of the inner wall of the connecting tube 1, and the other baffle plate 22 abuts against the bottom of the inner wall of the connecting tube 1. Through this operation mode, the hydrogen can be buffered by the channel formed by the multiple baffle plates 22 when flowing inside the connecting tube 1, and then the hydrogen flows into the interior of the hydrogen storage tank through the outlet 3. Through this operation mode, the impact force of the hydrogen entering the hydrogen storage tank can be weakened.

[0048] When hydrogen enters the connecting tube 1, it will impact the connecting tube 1, and the connecting tube 1 will vibrate. The long-term vibration of the connecting tube 1 will cause the internal components of the connecting tube 1 to vibrate. In severe cases, the components will become loose, causing problems such as loose sealing. When the connecting tube 1 is vibrated by the impact of hydrogen, the vibration of the connecting tube 1 will be transmitted to the movable plate 6, and the spring 20 inside the movable plate 6 will shake. Because silicone oil is injected into the second groove 19, the spring 20 will be resisted by the silicone oil during the shaking process, thereby consuming kinetic energy. Through this operation method, the shock absorbing effect of the connecting tube 1 is achieved, and the safety of the device is increased.

[0049] When the device is in use, the fan 7 is started, and the air flow outside the connecting tube 1 can be enhanced by the blowing of the fan 7. This operation mode can cool the outside of the connecting tube 1, so that the heat generated by the hydrogen buffering inside the connecting tube 1 can be quickly dissipated, thereby increasing the functional stability of the device.

[0050] After the use of the device is finished, the third electric slider 24 slides in the third slide groove 23 to make the lifting plate 5 move upward. When the lifting plate 5 slides to the preset position, the lifting slider 16 slides upward in the lifting slide groove 15 until the adapter 10 rises to the preset height position, and then the adapter 10 is driven to rotate by the second rotating motor 18 until the cleaning brush 13 rotates to the side facing the lifting plate 5. At this time, the first electric slider 9 slides in the first slide groove 8 to make the movable plate 6 move close to the lifting plate 5. When the movable plate 6 moves to the preset position, the cleaning brush 13 can abut against the outer side of the filter plate 21. The up and down sliding in the groove 11 can make the cleaning brush 13 move up and down on the outside of the filter plate 21. The filter plate 21 can be cleaned by this operation method, which increases the convenience of using the device; when the cleaning brush 13 on one side of the adapter 10 is brushing the filter plate 21, the fan 7 on the other adapter 10 is driven by the first rotating motor 17 to rotate at a preset angle, and then blow air, which can increase the cleaning effect of the cleaning brush 13 on the filter plate 21. The cleaning brush 13 on one adapter 10 can clean the filter plate 21 of one plate, and then the automatic cleaning of the filter plate 21 can be completed according to the above operation method, which increases the convenience of using the device.

[0051] If the filter plate 21 needs to be replaced, after the lifting plate 5 rises to a preset height, the bolts installed at the positioning block 29 are directly removed, and then the filter plate 21 is taken out from the third slot 28 for replacement.

[0052] Close the solenoid valve at the air outlet 3, and then inject hydrogen into the interior of the connecting tube 1 through the air inlet 2. After the preset amount is injected, close the solenoid valve at the air inlet 2. At this time, the air pressure sensor 27 can detect the air pressure inside the connecting tube 1 and transmit it to the background control system, and compare the changes in the air pressure value within the preset time through the background control system. If the air pressure value changes, it means that the air tightness of the connecting tube 1 is unqualified. Through this operation method, the air tightness of the connecting tube 1 can be detected, thereby increasing the safety of the device.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
