The marine seawater heat exchanger mainly comprises a left end cover, a right end cover, a tube plate, a gasket, a frame, a bolt, a nut and other structures, and leakage is likely to occur in the long-term use of the heat exchanger, and the marine seawater heat exchanger mainly comprises the following aspects:
(1) The sealing ring is aged and failed, or is crushed during installation, and the installation position is not in accordance with the requirement;
(2) The expansion joint of the copper pipe and the pipe plate does not meet the requirement, so that leakage is formed;
(3) The copper pipe is corroded and leaked by seawater, the inner part of the copper pipe is scratched to form pitting corrosion to cause perforation leakage, or the inner part is blocked to cause seawater to excessively speed to form leakage;
(4) Copper tubes are unreasonably installed, stress concentration is formed, and the copper tubes are broken.
The end cover and the tube plate of the seawater heat exchanger are mainly connected by bolts, hexagonal nuts and gaskets, the outer hexagonal nuts are characterized by larger fastening force, firm installation and difficult looseness, the defect is that enough space is needed during installation and disassembly, and common tools such as an adjustable spanner and an open spanner all need large operation space, so that the end cover and the tube plate are required to be removed when the seawater heat exchanger is leaked or cleaned.
The both sides of current circulation ventilation unit's sea water heat exchanger are steam heater and air-out static pressure case, if sea water heat exchanger need maintain and when inspection, lean on to twist the outside bolt of end cover and can't directly loosen the nut of inside alone, need only dismantle the steam heater and the air inlet case of heat exchanger both sides after just can leaving sufficient space and dismantle work, the maintenance task volume is big and inefficiency. Therefore, under the condition that the space of the ship is limited, the significance is particularly important how to repair the ship without dismantling the box body structures at the two sides on the basis of not changing the original structure.
Disclosure of Invention
The utility model aims to solve the problem that an end cover and a tube plate of a marine seawater heat exchanger are not easy to detach, and provides an easily-detached end cover structure of the seawater heat exchanger, which can efficiently detach and repair on the premise of not detaching a steam heater and an air outlet static pressure box, and solves the problems of small maintenance space, high maintenance difficulty and the like of a ship.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: an easily-detachable seawater heat exchanger end cover structure is arranged on two sides of a seawater heat exchanger end cover, and left and right tube plates are fixedly and detachably connected with a seawater heat exchanger body through a detachable fixing piece and an end cover mounting bolt group.
Further, bolt and nut fixing holes are formed in the upper end and the lower end of the body of the detachable fixing piece, so that the detachable fixing piece and the upper cover plate and the lower cover plate of the seawater heat exchanger are conveniently connected, and the firmness of the fixing piece is improved.
Further, the detachable fixing piece body is provided with bolt holes corresponding to the bolts of the external end cover one by one, and nuts are welded on the bolt holes.
The beneficial effects of the utility model are as follows:
compared with the prior art, the utility model has the main improvement that the easily detachable fixing piece is added in the seawater heat exchanger. The current air conditioner in the ship field mostly adopts a combined air conditioner design mode, and the structure forms of an air outlet static pressure box, a fan motor, a steam heater, a seawater heat exchanger, an air outlet box body and the like are adopted, if the seawater heat exchanger leaks or needs cleaning work, the current structure needs to be dismantled by the steam heater or the connecting box body on the left side and the right side.
The fixing piece is additionally arranged, and the end cover and the tube plate can be detached only by removing bolts outside the end cover on the premise that the connecting box bodies on two sides are not required to be removed, so that the maintenance efficiency is greatly improved. The heat exchanger has the advantages of simple and compact structure, easy processing, no change of the windward area of the heat exchanger and no influence on the heat exchange performance.
The utility model solves the problems of limited space and small maintenance space of the ship, is more suitable for special space requirements of ship maintenance, and provides conditions for efficiently solving the maintenance of the ship air conditioner.
Drawings
FIG. 1 is a schematic diagram of a seawater heat exchanger;
fig. 2 is a removable fastener structure of the present utility model.
Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1, the seawater heat exchanger mainly comprises an end cover mounting bolt group 1, a left end cover 2, a left tube plate 3, an upper cover plate 4, a right end cover 5 and a detachable fixing piece 6. The bolt is fixed by the quick and easy-to-detach fixing piece of the end cover, and the bolt group is detached by a wrench at the front side of the end cover when the seawater heat exchanger is overhauled. The conventional seawater heat exchanger is provided with a quick and easy-to-detach fixing piece without an end cover, and the seawater heat exchanger is required to be separated from the box body and the left and right end covers are required to be detached after the seawater heat exchanger is extracted during maintenance.
As shown in figures 1 and 2, the end cover structure of the easily-detachable seawater heat exchanger is arranged on two sides of the end cover of the seawater heat exchanger, and bolt and nut fixing holes are formed in the upper end and the lower end of the detachable fixing piece 6, so that the detachable fixing piece 6 can be conveniently connected with the upper cover plate and the lower cover plate, and the firmness of the fixing piece is improved. The nut 6-2 is fixed on the detachable fixing piece body 6-2 through welding, and when the heat exchanger needs to be maintained, the purpose of disassembling the seawater heat exchanger can be achieved only by screwing the bolt outside the end cover. The structure can be used for the air conditioner of the same type and has wide adaptability.
As shown in fig. 1 and 2, the utility model provides a detachable fixing piece, which has the following characteristics compared with the existing detachable structure:
(1) The left and right tube plates 2,3 are provided with detachable fixing pieces 6 on both sides, 4 in total.
(2) Bolt and nut fixing holes are formed in the upper end and the lower end of the detachable fixing piece body 6-1, so that the detachable fixing piece 6 and the upper cover plate and the lower cover plate are conveniently connected, and the firmness of the detachable fixing piece 6 is improved.
(3) The detachable fixing member body 6-1 is provided with bolt holes corresponding to the bolts of the outer end cover one by one, and the nuts 6-2 are welded on the bolt holes of the detachable fixing member body 6-1.
Therefore, the end cover structure of the easily detachable seawater heat exchanger has the following advantages:
(1) The detachable fixing piece has simple structure, easy processing and forming, compact structure, no change of windward area of the heat exchanger and no influence on the performance of the heat exchanger;
(2) The steam heater and the air outlet static pressure box on two sides of the heat exchanger do not need to be removed, so that the maintenance efficiency is improved;
(3) Because the upper end and the lower end of the detachable fixing piece are fixed with the cover plate, and the nut and the fixing piece adopt an integrated welding structure, the end cover can be detached only by loosening the external bolt of the end cover;
(4) The problems of small maintenance space, high maintenance difficulty and the like of the ship are solved.
