The annular liquid channel inner ring plate 44 and the annular liquid groove outer ring plate 45 are disposed between the inner groove plate 42 of the liquid tank and the outer ring plate 43 of the liquid tank.

The annular liquid tank 4 is in the non-cooling zone, and includes a liquid tank bottom plate 41, and a liquid tank inner ring plate 42 and a liquid tank outer ring plate 43 fixedly disposed on the liquid tank bottom plate 41. The annular liquid tank 4 is not provided with an annular liquid tank inner ring plate 44 and an annular liquid channel outer ring plate 45 in the non-cooling zone. Referring to Fig. 2, an annular duct end seal 1 is provided at both ends of the non-cooling zone.

Since the annular air passage is specifically a passage between the annular liquid groove 4 and the door type sealing device 3 which are continuously arranged in a full circle; and the movement of the door type sealing device 3 includes both a circumferential movement and a radial direction R (relative ring) Cold machine center) Reciprocating swing of the direction. Therefore, it is difficult to ensure the uniformity of the distance between the inner ring plate 44 of the annular liquid channel and the inner ring plate 31 of the door type air duct, and the outer ring plate of the annular liquid channel The consistency of the distance between the 45 and the door type outer ring plate 32.

Since the distance between the door type inner ring plate 31 of the door type seal device and the outer type outer ring plate 32 of the door type air passage is determined, as long as it is in the radial direction (relative to the center of the ring cooler), the ring plate in the door type air duct 31 between the door-type air duct outer ring plate 32, in the height direction between the liquid level of the annular liquid tank 4 and the door type seal cover 33, sealing is performed, and the air between the cooling zone and the non-cooling zone can be satisfied. Or the requirement for a small amount of air leakage.

Therefore, the annular liquid tank 4 includes only the liquid tank bottom plate 41 in the non-cooling zone, and the liquid tank inner ring plate 42 and the liquid tank outer ring plate 43 fixedly disposed on the liquid tank bottom plate 41 without the annular liquid groove wind. The inner ring plate 44 and the annular liquid groove outer ring plate 45 are such that the liquid in the annular liquid tank 4 is between the inner groove ring plate 42 and the outer groove plate 43 of the liquid tank.

Since there are moving door seals in both the cooling zone and the non-cooling zone, and the door seal cover 33 has a through hole 34 to the trolley, it is required to be provided at both ends of the non-cooling zone for The annular duct end seal 1 of the annular duct is sealed. This ensures that there will be no air leakage or low air leakage in the non-cooling zone.

The width of the annular duct end seal 1 is equal to the distance between the door type inner ring plate 31 of the door type sealing device 3 and the door type outer ring plate 32.

The space enclosed by the door type outer ring plate 32 and the annular liquid groove bottom plate 41 performs a single air leakage prevention seal. The sealing of the cooling zone and the non-cooling zone of the annular duct according to the embodiment of the invention can be sealed by the annular duct end seal.

In order to facilitate the understanding of those skilled in the art, the structure of the annular air duct end seal body according to the embodiment of the present invention will be specifically described below with reference to FIGS. 5 and 6.

5 and FIG. 6, FIG. 5 is a plan view of the annular air passage end seal body according to the embodiment of the present invention; and FIG. 6 is a cross-sectional view taken along line C-C of FIG.

The annular duct end seal body 1 according to the embodiment of the present invention includes a seal body 11 disposed at the bottom of the annular liquid tank 4, and a seal member 12 fixed to the seal body 11 and having the same height as the seal body 11.

The sealing body 11 is located between the door type inner ring plate 31 and the door type outer ring plate 32. Seal The main body 11 includes a main body top plate and four side panels. In order to ensure that the door-type sealing device 3 passes through the annular duct end seal body 1, the cold air in the annular duct does not flow into the non-cooling zone on the side of the annular duct end seal body 1, and the radial dimension of the main body top plate The lateral dimensions and the lateral dimensions are required to be greater than the radial and lateral dimensions of the through-holes 34 of the gate seal cover 33, respectively.

In order to ensure that the top plate of the sealing body 11 is rotated clockwise or counterclockwise in the center of the ring-type sealing device 3 (not shown), it can be well sealed with the door-type sealing device cover 33. Further ensuring that the cold air entering the annular duct does not enter the non-cooling zone on the side of the annular duct end seal 1 along the gap between the gate seal cover 33 and the top plate of the seal body 11 The upper plane of the top plate of the sealing body 11 needs to be in the same plane as the lower plane of the door seal cover 33, so that the four side plates are required to be equal in height.

When the sash seal cover 33 is moved above the annular duct end seal 1, the top plate of the seal body 11 is in contact with the door seal cover 33 and has relative movement, the seal 12 and the door The air duct inner ring plate 31 and the door air duct outer ring plate 32 are in contact with each other and have relative motion.

In order to further improve the sealing effect of the annular duct end seal 1 according to the embodiment of the present invention, it is required that the seal body 11 itself has a good seal. The sealing body 11 can be directly sealed and welded by four side plates and one main body top plate, or welded or connected by a member such as angle steel to form a hollow rectangular box without a bottom. And it is necessary to ensure a good sealing effect between the four side panels and one of the main panels. Since the sealing body 11 is constructed by four side plates and a main body top plate, the sealing body 11 is made of less material, and the quality of the sealing body 11 is alleviated.

Of course, the sealing body 11 can also be a solid or solid rectangular box, and the entire sealing body 11 can be regarded as a main body top plate, which realizes dynamic sealing during the relative movement with the door type sealing device cover 33.

The space between the annular air passage end seal body 1 and the door type inner ring plate 31 and the door type outer ring plate 32 flows into the non-cooling zone, and the seal 12 includes at least two groups respectively disposed at the same Both sides of the sealing body 11 adjacent to the door type inner ring plate 31 and the door type outer ring plate 32 On the board.

Each of the sets of the seal members 12 has a "several" shape of a projection 121 having a height equal to that of the sealing body 11. The projection 121 may be a "several" shaped projection extending through the height of the entire sealing body 11. When the gantry seal 3 is moved together with the trolley to the position of the annular duct end seal body according to the embodiment of the present invention, the "several" shaped protrusion 121 can prevent the cold air in the annular duct from the annular duct end seal 1 and The space between the door type inner ring plate 31 and the door type outer ring plate 32 enters the non-cooling zone. Of course, when the ring cooler trolley is eccentric due to problems such as the installation of the ring cooler, the gate seal device 3 may have a certain amount of radial displacement at the position of the annular air duct end seal body 1 (relative to the center of the ring cooler) The "several" shaped projections 121 may have a small amount of convex axial deformation, i.e., a radial displacement relative to the center of the ring cooler, thereby ensuring a dynamic seal therein.

Each of the sets of seals 12 may also include at least two connected and integral "several" shaped projections 121, and each of the "several" shaped projections 121 is of equal height to the sealing body 11.

Of course, in order to better ensure the dynamic sealing effect between the annular air passage end seal body 1 and the door type inner ring plate 31 and the door type outer ring plate 32, the adjacent two protrusions 121 have A predetermined size of the connecting portion 122, the sealing member 12 is provided with a spacer 123 below each connecting portion 122, and the sealing member 12 is fixedly mounted to the spacer 123 and the sealing body 11 by mechanical mounting.

Each of the sets of the sealing members 12 is a unitary body, that is, the connecting portion 122 between the two adjacent protrusions 121 is integral with the adjacent protrusions 121. Since the spacer 123 is disposed below each of the connecting portions 122, and the sealing member 12 and the spacer 123 and the sealing body 11 are fixed to each other, each of the projections 121 has a radial displacement space (relative to the center of the ring cooler) .

The size of the connecting portion 122 between the two adjacent projections 121 and the thickness and strength of the spacer 123 can be set in accordance with the size and mounting accuracy of the ring cooler. As long as the maximum radial displacement of the door type sealing device 3 is satisfied, the dynamic sealing between the annular air passage end seal body 1 and the door type inner ring plate 31 and the door type outer ring plate 32 can be ensured.

In order to further improve the dynamic sealing effect between the sealing body and the door type inner ring plate 31 and the door type outer ring plate 32, the annular air channel end sealing body 1 according to the preferred embodiment of the present invention The sealing member 12 is respectively disposed at the left and right ends of the side plates of the sealing body 11 adjacent to the door type inner ring plate 31 and the door type outer ring plate 32. Each set of the sealing member 12 may also completely cover the two side plates of the sealing body 11 adjacent to the door type inner ring plate 31 and the door type outer ring plate 32 to improve The dynamic sealing effect between the annular air passage end seal body 1 and the door type inner ring plate 31 and the door type outer ring plate 32.
