Description

Technical Field

[0001] The utility model relates to the technical field of transfer pipes for grinding stations, in particular to a transfer pipe of a grinding station which is tightly connected. Background Art

[0002] During combustion and power generation, a large amount of fly ash will be generated. The fly ash needs to be transported to the vicinity of the transition bin of the grinding station by an ash storage vehicle. The ash delivery pipe on the fly ash is connected with the transfer pipe on the transition bin. The fly ash is delivered to the transition bin through the ash delivery pipe and the transfer pipe by wind power. The fly ash is temporarily stored in the transition bin to facilitate subsequent grinding of the fly ash.

[0003] The existing transfer pipe and ash delivery pipe are usually connected together by flanges. A flange is fixed at one end of the transfer pipe and the ash delivery pipe, a sealing sheet is fixed between the two flanges, and the two flanges are fixed together by a number of bolts, so that the transfer pipe and the ash delivery pipe are fixed together.

[0004] When the existing transfer pipe and ash delivery pipe are in use, in the process of delivering fly ash into the transition bin by wind, the air pressure inside the transfer pipe and the ash delivery pipe is relatively high, so that the connection between the transfer pipe and the ash delivery pipe will be subjected to a relatively large thrust, thereby causing the two flanges and a number of bolts to be subjected to a relatively large thrust, which can easily cause the bolts to loosen or break, causing the connection between the two flanges to loosen, thereby reducing the sealing of the connection between the transfer pipe and the ash delivery pipe.

[0005] In order to solve the above problems, the present application proposes a transfer pipe of a tightly connected grinding station. Utility Model Content

[0006] To solve the problems raised in the above background technology. The utility model provides a transfer pipe of a grinding station that is tightly connected, and the transfer pipe body and the ash delivery pipe can be fixed together through a sealing seat and a support block. The larger contact area between the sealing seat and the support block can more evenly distribute the pressure to the entire structure, reducing local pressure concentration, thereby reducing the risk of damage to the sealing seat and the support block, so that the connection between the ash delivery pipe and the transfer pipe body is not easy to loosen, thereby improving the sealing characteristics of the connection between the ash delivery pipe and the transfer pipe body.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transfer pipe of a tightly connected grinding station, comprising a sealing seat, a fixing groove is provided on one side of the sealing seat, a transfer pipe body is fixedly provided inside the fixing groove, a fixing ring is fixedly provided inside the fixing groove, a first sealing ring is provided on the side of the fixing ring, a movable groove is provided on the other side of the sealing seat, a movable seat is provided inside the movable groove, four support blocks are fixedly provided on the side of the movable seat, a plurality of bolts are provided inside the sealing seat, a sealing groove is provided inside the movable seat, the inside of the sealing groove is fitted with the side of the first sealing gasket, an ash delivery pipe is provided inside the movable seat, a rotating ring is fixedly provided at one end of the side of the ash delivery pipe, and a second sealing ring is fixedly provided on the side of the rotating ring.

[0008] As a preferred transfer pipe of a tightly connected grinding station of the utility model, a placement groove is opened inside the transfer pipe body, and the inside of the placement groove is respectively fitted with the side surfaces of the four support blocks. The transfer pipe body is convenient for delivering the fly ash into the transition bin.

[0009] As a preferred transfer tube of a tightly connected grinding station of the utility model, a plurality of first limiting holes are opened inside the sealing seat, and the side surfaces of the plurality of bolts are respectively connected to the internal threads of the plurality of first limiting holes, so that the bolts can easily fix the support block and the sealing seat together.

[0010] As a preferred transfer tube of a tightly connected grinding station of the utility model, a plurality of second limiting holes are opened inside the four support blocks, and the interiors of the plurality of second limiting holes are respectively threadedly connected to the side surfaces of a plurality of bolts, so that the support blocks facilitate fixing the movable seat and the sealing seat together.

[0011] As a preferred transfer pipe of a tightly connected grinding station of the utility model, a rotating groove is opened inside the movable seat, and the inside of the rotating groove fits with the side of the second sealing ring, and the movable seat is convenient for fixing the ash delivery pipe and the sealing seat together.

[0012] As a preferred transfer pipe of a tightly connected grinding station of the utility model, four through grooves are opened on the other side of the sealing seat, and the four through grooves are all located on the side of the movable groove, so that the sealing seat can easily limit the support block.

[0013] As a preferred transfer tube of a tightly connected grinding station of the utility model, a positioning groove is opened on the side of the fixed ring, and the interior of the positioning groove is fixedly connected to the inner side of the first sealing ring.
