Description

Technical Field

[0001] The utility model relates to the technical field of fermentation devices, in particular to a door panel opening and closing structure of a space capsule. Background Art

[0002] Large anaerobic fermentation tanks often require submersible mixers to promote the flow and mixing of biogas slurry in the fermentation tank. In order to remove the submersible mixer for maintenance and repair without cleaning the tank, we invented a space capsule structure. The submersible mixer can be retreated into the space capsule first, and then the hatch can be closed to cut off the connection between the biogas slurry in the tank and the outside of the tank, and then the submersible mixer can be taken out from the space capsule.

[0003] Existing technical solutions for opening and closing hatches are as follows Figure 1 As shown, a bearing 2 is arranged on the door panel 1 and connected to the space capsule 3. A first steel wire rope 4 is connected to the door panel 1, and the steel wire rope is connected to a sealing rod 6 through a pulley 5. The sealing rod 6 can slide in a sealing mechanism 7 installed on the tank wall, and one end extends out of the tank and is connected to a second steel wire rope 8. The second steel wire rope 8 is retracted and released by a winch 9. By shaking the winch 9 to retract the second steel wire rope 8, the sealing rod 6 can be pulled toward the outside of the tank; the first steel wire rope 4 is driven to make the door panel 1 rotate around the bearing 2, thereby opening the cabin door, and the winch 9 is shaken in the opposite direction to release the second steel wire rope 8. Under the action of the gravity of the door panel 1, the sealing rod 6 slides into the tank, and the cabin door sags around the hinge, thereby closing the space capsule.

[0004] In the above-mentioned space capsule structure, the door panel is opened and closed by tightening or loosening the wire rope. The connection of the wire rope is unreliable and easy to loosen. In addition, the long fiber debris in the biogas slurry in the tank is easy to accumulate on the pulley and other places in the tank, which can easily cause the wire rope to get stuck and the door panel cannot be opened. In addition, there are problems such as loose connection between the wire rope and the door panel causing the door panel to sag, and loosening the wire rope and relying on gravity to close the door panel loosely, resulting in a high failure rate in the use of the device. Utility Model Content

[0005] The purpose of the utility model is to provide a space capsule door panel opening and closing structure for solving the above problems. The technical solutions adopted are as follows:

[0006] A door panel opening and closing structure for a space capsule comprises a fermentation tank, a space capsule, and a door panel, wherein the door panel is rotatably connected to the space capsule via a rotating shaft, and is characterized in that it also comprises a steering reducer and a rotating handle, wherein the steering reducer input shaft is fixedly connected to the rotating handle, one end of the rotating shaft extends out of the fermentation tank and is coaxially fixedly connected to the steering reducer output shaft, and a sealing structure is arranged between the rotating shaft located outside the fermentation tank and the outer wall of the fermentation tank.

[0007] Furthermore, the sealing structure comprises a sleeve, which is sleeved on the outside of the rotating shaft, one end of the sleeve is fixedly connected to the outer wall of the fermentation tank, and a rotating shaft seal is arranged between the other end and the rotating shaft.

[0008] The beneficial effects of the utility model are as follows: the device drives the rotating shaft to rotate through the steering reducer to realize the opening and closing of the space capsule door panel, the structure is simple and reliable, and the fermentation tank can be sealed by the arranged sleeve and the rotating shaft seal to avoid leakage of the biogas slurry in the fermentation tank.
