Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen production, and more specifically, relates to a hydrogen preparation desulfurization tank. Background Art

[0002] There are many ways to prepare hydrogen. When producing hydrogen from natural gas, the extracted hydrogen needs to be desulfurized. When desulfurizing hydrogen, the hydrogen needs to be discharged into the desulfurization bin inside the desulfurization tank, and then the desulfurizer is added into the desulfurization bin. The desulfurizer desulfurizes the hydrogen, and the hydrogen is discharged after desulfurization is completed. After the desulfurizer inside the desulfurization bin has been used for a period of time, the desulfurizer is discharged into the waste bin, and the desulfurizer inside the waste bin is cleaned regularly.

[0003] According to CN202120269130.0, the utility model discloses a hydrogen preparation desulfurization tank, comprising a box body, a placement plate and a desulfurization bin, a waste bin is provided below the box body, and a scraper is installed on the left side of the waste bin, a cleaning roller is installed above the scraper, and a limiting block is connected to the right side in front of the cleaning roller, a placement plate is installed in the middle of the box body, and a gear is connected to the left side of the placement plate, a limiting plate is installed on the rear side of the placement plate, and an adjusting screw is connected to the middle right side of the limiting plate, a feed port is provided on the upper surface of the box body, and a desulfurization bin is installed above the box body, a gas transmission pipe is provided on the left side of the gas transmission port, and an air suction pump is installed in the middle of the gas transmission pipe. The hydrogen preparation desulfurization tank is provided with a placement plate, a gear, a gear rod, a limiting plate and an adjusting screw, which facilitate the clamping of the placement plate by the limiting plate and ensure the sealing in the desulfurization bin, and the setting of the gear and gear rod makes it easy to flip the placement plate, so that the desulfurizer above it is easy to pour out.

[0004] Based on the above, the desulfurizer is generally placed inside the existing desulfurization tank through the bottom plate structure, and the desulfurizer is discharged into the waste bin by rotating the bottom plate. When discharging the desulfurizer into the waste bin, the staff needs to first control the hydrogen to stop discharging into the desulfurization bin, and then operate the bottom plate to rotate to discharge the desulfurizer into the waste bin. After the discharge is completed, the hydrogen is controlled to continue to be discharged into the desulfurization bin. The operation is relatively cumbersome. Utility Model Content

[0009] Furthermore, the bottom plate opening mechanism also includes: a first bevel gear, a connecting shaft and a second bevel gear; the first bevel gear is coaxially fixedly connected to the right side of a group of opening shafts on the front side; the connecting shaft is rotatably connected to the inside of the right side of the tank body; the second bevel gear is coaxially fixedly connected to the front side of the connecting shaft, and the first bevel gear and the second bevel gear are meshed together to form a bevel gear transmission mechanism.

[0010] Furthermore, the bottom plate opening mechanism also includes: a third bevel gear and a fourth bevel gear; the third bevel gear is coaxially fixedly connected to the rear side of the connecting shaft; the fourth bevel gear is coaxially fixedly connected to the right side of a group of opening shafts on the rear side, and the third bevel gear and the fourth bevel gear are meshed together to form a bevel gear transmission mechanism.

[0011] Furthermore, the cleaning and blocking mechanism includes: a starting pulley, a blocking transmission belt, a blocking shaft and a blocking pulley; the starting pulley is coaxially fixedly connected to the left side of a group of opening shafts on the front side; the blocking shaft is rotatably connected to the upper side of the inner front end face of the tank body; the blocking pulley is coaxially fixedly connected to the left side of the blocking shaft; the blocking transmission belt is transmission-connected to the starting pulley and the outer end face of the blocking pulley.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model adopts a bottom plate opening mechanism to place the desulfurizer on the containing bottom plate. The staff turns the opening turntable to rotate and drives the two groups of containing bottom plates inside the tank body to rotate. After the two groups of containing bottom plates rotate, the desulfurizer falls into the waste bin, ensuring that the desulfurizer falls into the waste bin quickly.

[0015] The utility model adopts a cleaning blocking mechanism, which realizes that when the containing bottom plate rotates, the blocking cover is driven to rotate, and the blocking cover rotates to block the hydrogen feed port, so that hydrogen cannot enter the interior of the tank body, thereby avoiding the problem of staff stopping the delivery of hydrogen before cleaning the desulfurizer, saving the staff's operating steps, and at the same time avoiding the problem of hydrogen leakage inside the tank body due to forgetting to stop the delivery of hydrogen when cleaning the desulfurizer, and ensuring that the delivery of hydrogen is stopped when cleaning the desulfurizer.
