Problems solved by technology
[0002] Heat exchangers are mostly used in the chemical industry for heat exchange between hot and cold fluids. The disadvantage of most heat exchangers today is that some heat exchangers used in chemical plants are too high from the ground to protect workers during maintenance. Climbing up to the top of the heat exchanger increases the potential safety hazard. Another common disadvantage is that the maintenance period is long, because the head and the cylinder are mostly connected by bolts and nuts, and because the heat exchanger has high sealing requirements, it takes a lot of maintenance. A large number of bolts and nuts are used to fix the head and the cylinder to ensure the tightness of the heat exchanger, which leads to a long time to disassemble the head, which leads to low work efficiency, the volume of the head is too large, and the head is shut down for maintenance. The problem of inconvenient placement also needs to be solved. During the maintenance process, the liquid remaining in the heat exchange tubes in the heat exchanger is easy to flow out from the heat exchange tubes or the shell, causing injury to workers

The invention discloses a heat exchanger convenient to maintain. The heat exchanger comprises a barrel body, a working space is formed in the barrel body, a folding space is formed in the upper side wall of the working space, an uncovering device facilitating opening and closing of the working space is arranged among the working space, the right side of the barrel body and the upper side of the barrel body, and the uncovering device comprises a rotating lock disk rotatably arranged in the working space. According to the heat exchanger, sealing and opening of a seal head and the barrel body canbe controlled through a pair of gears which rotate relatively, so that the problem about low seal head disassembling efficiency is solved; the seal head is lifted through a connecting rod mechanism to move to a designated position, so that the problem of seal head placing during maintenance is solved; and in the aspect of safety, the function of folding a pedal at the top of the barrel body is achieved through a cam mechanism and the connecting rod mechanism.
