The structure and common type of AAC autoclave


AAC Autoclave is a kind of container which processes aerated concrete, and lime brick, fiyash bricks and so on,and finish the Cao-Sio2-H2o hydrothermal reaction. At the same time, it is widely used in other projects, for example,rubber products, wood drying and preservative treatment, heavy metal smelting, coal oil seepage firebrick invasion, consistent glass steam curing, high pressure treatment chemical products, canned food high pressure processing, pulp cooking, cable vulcanization, fishnet stereotypes as well as chemical, pharmaceutical , aerospace industry, insulation materials, textile workers, military and other support required pressure steam production process of production projects. Meanwhile, autoclave is a very dangerous machine because it works under high pressure, so for the safety’s sake, the user have to grasp the knowledge of the autoclave structure.

The structure and common type of AAC autoclave

An autoclave is composed of the body, the door, the gas distributing and safety valve. The AAC autoclave body is the main parts which is a container to bake the products as well as the carrier of module car, the plate, and the products. The kettle circle functions as an connector between the body and the door, which is also a seal tool. The kettle door can separate the interior part from the outside. The gas distributing pipe equally distribute the high pressure steam from outside in the autoclave. Water scattering machine is used to separate the the steam and discharge the condensate water while the safety valve functions to discharge the steam water in urgent circumstances. The autoclave manufactured by our company are the common ones which include such type as 1.65x21m¢, 2x21m¢、2.68x32m¢、2.85x26m¢ and 2.85x39m¢. Divided by the work pressure, they are 1.2mpa, 1.3mpa and 1.5mpa. By the form of door starting ,they are side-open,bottom-open , hydraulic pressure-open, air pressure driven-open, electric-driven open, hand-driven open.

AAC Autoclave Structure

1. Autoclave body: it is mainly welded cylinder and Autoclave body flange. Rail is laying in the bottom of autoclave, for walking or parking the steam-curing car.Various of pipes arranged on the Autoclave body to exhaust steam and discharge condensed water and install all kinds of valves.
2. Autoclave cover: mainly welded Autoclave cover flange and spherical head.
3. Clamp: clamp is a whole ring forging, flange groove is set inside the clamp ring, on both sides of the flange groove around the circumference in distributes the flange groove-tooth. The tooth of Autoclave body flange and Autoclave cover flange are inside the flange groove. Meshing or demeshing respectively with the Autoclave cover and Autoclave body flange tooth as clamp rotating,  the autoclave will close or open.
4. Swinging device: composed of counterweight box, swinging arm, support plate and other components. So Autoclave cover can swing up and down.
5. Rotary-hoop-gear component: in the opening door system, gear for clamp is manual and spare parts. It does not need to install when normal use.

6. Support: used to bear Autoclave body and made up of intermediate support, movable support, and end support. In addition to the intermediate support, other supports can move along the axial with the aid of roller when thermal expansion and contraction in the autoclave.
7. Insulation: to reduce heat loss when using autoclave (according to the nature and thickness of insulation material, users can control the Autoclave temperature by themselves ).
8. Sealing device: Made up of rubber sealing ring, cut-off valve and steam-inlet valve. The rubber sealing ring is set inside the sealing groove of Autoclave body flange, sealed steam will flow into sealing groove when autoclave operating, sealing ring will close against Autoclave cover and realize air-proofing.
9. Valve instruments: including pressure gauge, safety valve, thermometer or thermal resistance, ball valve, etc., for observing the autoclave operation.
10. Drainage device: including drainage pipe connector, steam trap, drainage valve, etc. Sinking in the pipe connector, condensed water flows out through the trap to avoid solid particle plugging trap; Drainage valve should discharge the condensed water and sludge whether regularly or not.
11. Electrical safety interlock devices: including control cabinet, electric- contact pressure gauges (or called as pressure transmitter), pressure warning unit, etc. all meet the 3rd, 20th requirements of Stationary Pressure Vessel Safety and Technology Supervision Regulation, to ensure security operation of autoclave.
