Description

Heat exchanger head Technical Field The utility model relates to a heat exchanger seal head, and belongs to the field of heat exchangers. Background The heat exchanger seal head is a key part of a heat exchanger and is positioned at the end part of equipment and mainly plays a role in sealing and connecting, the oval seal head is one of common heat exchanger seal heads, the oval seal head consists of a half oval and a straight edge, can bear higher pressure due to good stress performance and is widely applied to medium-high pressure heat exchangers, and in the equipment such as the heat exchanger, a baffle is welded inside the oval seal head and is used for separating the inner space of the oval seal head, so that medium can flow through two independent spaces in the seal head respectively. The oval head has a greater depth due to its unique structure, which, while contributing to the performance optimization of the device in some respects, also presents challenges for the installation of the internal baffles. When the partition plate is required to be fixed inside the elliptical end socket in a welding mode, the space which can be provided for welding operation is very limited due to the fact that the space inside the end socket is relatively narrow. Under such a limited environment, it is difficult for a welder to flexibly develop a welding tool and an operation method, and the difficulty is increased in precisely controlling the welding angle and the welding position. Moreover, the limited space makes the ventilation condition in the welding process poor, and the smog and the waste gas that welding produced are difficult to discharge rapidly, not only influence the sight of welding personnel, can also cause certain harm to its health. In addition, welding is performed in a narrow space, special requirements are also provided for the size and flexibility of welding equipment, and conventional welding equipment can not meet the operation requirements, so that the welding difficulty is further increased, and various technical difficulties and challenges are faced in the whole welding process. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a heat exchanger seal head so as to solve the problems in the background art, and the utility model avoids complex operation of welding a baffle inside a narrow seal head. In order to achieve the purpose, the heat exchanger seal head is achieved through the following technical scheme that the heat exchanger seal head comprises a barrel, a detachable plug cover is arranged at one end of the barrel, a baffle is welded in the plug cover, one end of the baffle, which is far away from the plug cover, extends into the barrel, a liquid inlet pipe head and a liquid outlet pipe head which are symmetrically arranged relative to the baffle are arranged on the outer surface of the barrel, two U-shaped frames which are symmetrically arranged are arranged on two parallel side surfaces of the baffle, a support bar is arranged at one end of the U-shaped frame, which is far away from the baffle, a sealing strip is arranged at one surface of the support bar, which is far away from the center area of the baffle, four splicing grooves matched with the sealing strip are formed in the inner wall of the barrel, one end of the sealing strip, which is far away from the support bar, is inserted in the splicing grooves, the sealing strip is tightly attached to the inner wall of the splicing grooves, and the length of the U-shaped frame is identical to that of the splicing grooves. Further, one end of the cylinder body, which is close to the blanking cover, is sleeved with a first connecting ring which is fixedly connected with the cylinder body, one side of the first connecting ring is provided with a second connecting ring which is matched with the first connecting ring, the second connecting ring is sleeved on the blanking cover and is fixedly connected with the blanking cover, and the first connecting ring is connected with the second connecting ring through a fastener formed by a plurality of groups of screws and nuts. Further, a sealing ring is arranged between the cylinder body and the blanking cover, the sealing ring is arranged between the first connecting ring and the second connecting ring, and one end of the screw penetrates through the sealing ring. Further, one surface of the sealing strip, which is far away from the supporting strip, is a first arc-shaped surface, one surface of the plugging slot, which faces the supporting strip, is a second arc-shaped surface, and the first arc-shaped surface and the second arc-shaped surface are mutually attached. Further, one end of the cylinder body far away from the blanking cover is sleeved with a flange ring which is fixedly connected with the cylinder body, and a plurality of round holes are formed in one side surface of the flange ring at equal intervals in an annular mode.
