Description

Technical Field

[0001] The utility model relates to a sealing door. Background Art

[0002] The furnace body is an energy conversion device. The energy input into the furnace body includes chemical energy and electrical energy in the fuel. The furnace body outputs steam, high-temperature water or organic heat carrier with a certain thermal energy, which is converted into mechanical energy through a steam power device, or the mechanical energy is converted into electrical energy through a generator. The furnace body that provides hot water is called a hot water furnace body, which is mainly used in life and also has a small number of applications in industrial production. The furnace body that produces steam is called a steam furnace body.

[0003] When an existing boiler is in use, it is necessary to seal the end face of the boiler. When a traditional sealed door is in use, it is generally to directly close and seal the hinged sealed door, which will cause air leakage at the hinge connection, resulting in a decrease in internal pressure and temperature, increasing energy loss, and squeezing the sealed door under high pressure, posing certain safety hazards.

[0028] The utility model provides a sealing door.

[0029] like Figure 1-2As shown, the sealed door provided by the embodiment of the utility model comprises a door frame 10 having a door opening 11, a door body 20 rotatably mounted on the door frame 10, a first locking structure 30 is provided on the door body 20, and a second locking structure 40 is provided on the door frame 10. The first locking structure 30 and the second locking structure 40 can be switched between connection and disconnection, so that the door body 20 can be switched between the following two states:

[0030] When the first locking structure 30 and the second locking structure 40 are connected, the door body 20 covers the door frame 10 and can block the door opening 11;

[0031] When the first locking structure 30 and the second locking structure 40 are disconnected, an inclined angle is formed between the door body 20 and the door frame 10 and the door opening 11 is exposed.

[0032] In this embodiment, the door body 20 is rotatably mounted on the door frame 10 via the second hinge shaft 14, so that the door body 20 can be locked to the door frame 10 through the cooperation of the first locking structure 30 and the second locking structure 40, thereby improving the sealing performance when closed. The door body 20 is loosened under the action of internal pressure, thereby improving the firmness of the door body 20. Among them, by arranging a sealing ring 16 around the door opening 11, when the door body 20 is pressed against the door frame 10, the sealing performance can be improved by the sealing ring 16.

[0033] Specifically, the first locking structure 30 is a locking arm provided on the door body 20, and the locking arm has a locking hole 34. The second locking structure 40 is a locking positioning shaft provided on the side of the door frame 10. That is to say, in the present application, the locking hole 34 is clamped on the locking positioning shaft to achieve the cooperation between the two.

[0034] The locking arm includes a connecting arm 31 and a holding arm 32 disposed at both ends of the connecting arm 31. The holding arm 32 is rotatably connected to the side wall of the door body 20 via a first hinge shaft 33. The locking hole 34 is disposed on the holding arm 32, and the locking positioning shaft can be held in the locking hole 34. In this embodiment, an external force can be applied to the connecting arm 31 to rotate the holding arm 32 outward around the first hinge shaft 33, and then the connecting arm 31 is pushed to cover the door body 20 on the door frame 10, and then the holding arm 32 is rotated inward to hold the locking hole 34 on the locking positioning shaft, thereby completing the cooperation between the two.

[0035] At the same time, the clamping arm 32 is provided with a first connection hole 35, and the door frame 10 is provided with a second connection hole 12. The first connection hole 35 and the second connection hole 12 can be aligned when the locking and positioning shaft is clamped in the locking hole 34. Therefore, when the locking and positioning shaft and the locking hole 34 are matched, the first connection hole 35 and the second connection hole 12 can be sequentially penetrated by a pin shaft to limit them, so as to improve stability and sealing ability. In addition, when opening, since the clamping arm 32 is provided with a bolt hanging rope hole 36, the pin shaft can be inserted to the bolt hanging rope hole 36. Alternatively, a rope is used to penetrate the bolt hanging rope hole 36 and the bolt is installed on the rope to prevent the bolt from falling off and being lost.

[0036] In the above embodiment, the door body 20 is provided with a locking shaft 50, and the door frame 10 is provided with a fastening hole 13, and the locking shaft 50 can be extended into the fastening hole 13 in a rotating manner when the door body 20 is covered on the door frame 10. In this embodiment, after the above operation is completed, the locking shaft 50 is aligned with the fastening hole 13, so that the locking shaft 50 can be extended into the fastening hole 13 by rotating the locking shaft 50 (the outer wall surface of the locking shaft 50 and the inner wall surface of the fastening hole 13 are threadedly matched), so as to further strengthen the connection performance between the door body 20 and the door frame 10.

[0037] The end of the locking shaft 50 is connected to a hand wheel 60 which can drive the locking shaft 50 to rotate, so the locking shaft 50 can be rotated by rotating the hand wheel 60 .

[0038] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
