Description

Quick detach formula access door structure and unit filter segment Technical Field The utility model relates to the technical field of filtering equipment, in particular to a quick-dismantling access door structure and a unit filtering section. Background In the field of industrial production, air treatment equipment is widely applied by virtue of functions of adjusting air parameters, removing harmful substances and the like, and in order to meet the high-efficiency operation requirement of the air treatment equipment, equipment air inlets are often provided with functional components such as a filter device and the like which need to be overhauled, so that an overhauling port is arranged. The traditional access door device with the air port flange with the filtering function generally adopts a single-layer plate structure, and the access door is fixed to the access port by arranging a plurality of bolts around. However, this conventional design exposes a number of drawbacks during actual service. The mode that a large amount of bolts are fixed is adopted, the disassembly and assembly process is time-consuming and labor-consuming, the special tool is relied on for operation, the problem that the loss of the bolts is serious still exists, the condition that the bolts are broken in the bolt holes happens during maintenance, and the access door cannot be normally installed directly. In addition, the flange access hole has large self weight, is inconvenient to place after being taken down, has extremely high operation difficulty in high-altitude or narrow-space operation, and is extremely inconvenient to operate because an access door is required to be integrally disassembled during installation.
