1. Full Automatic Autoclave Product Description:
The main product is autoclave aerated concrete block, it is the core equipment of production line. Once the failure will cause the embryo out of kettle and equipment can’t operate substandard conditions, so the safe operation is extremely important. Autoclave is the hydration reaction of silicate products, the main equipment to obtain the physical and mechanical properties. The operation used in aerated concrete block production is the main content of relationship between production safety and energy utilization.
2. Autoclave structure
The main parts of autoclave are autoclave door ,body apparatus, tank cover device, the door swing device, hand reducer, safety interlocks, bearings, insulation,,sealing devices, plumbing valves and meters, etc., also attached with drainage and electric control devices. Various structural designs and manufacturing can be safe and reliable, also can ensure the autoclave more stable in performance.
3. The safe operation of steam autoclave details:
Autoclave operation is simple, but very important, the operation process is generally good, both inside and outside the rail bridge connecting kettle, the car pulled into the kettle, kettle and check the ends of parking position properly, the withdrawal of the bridge, close the kettle door (in the pot ring coated with graphite lubricant, inflate the seal, should be closed before then the vacuum, by heating, cooling, air curing temperature, finally open the door to a kettle. Autoclave in operation should pay attention to the following points:
3. 1. The safety valve
The safety valve is in the autoclave pressure exceeds the limit, the automatic unloading components, therefore, as the pressure vessel autoclave should be equipped with more than two safety valves, so that when a failure of the other one still use. Safety valve opening pressure should be rated according to the allowable working pressure autoclave to adjust, should be slightly lower than the allowable pressure value, in order to ensure the good performance of the safety valve must be regular maintenance and daily maintenance work.
3. 2. The kettle door switch
The products into the kettle, should carefully manage the cauldron gate, is in engagement with the kettle kettle door ring, and pull down the safety. In the air before checking kettle door closed. Complete the maintenance, before opening the kettle door must pay attention to whether there is pressure vessel inspection, and the first to open the safe, put the residual gas after open the kettle door, and pay attention to avoid the operator facing the cauldron gate, in order to prevent the high temperature waste heat burns.
3. 3. The sealing ring
Between the door and the kettle kettle ring for sealing ring is a rubber product in each reactor closed door should be in the pot ring doped graphite coating lubricant to reduce friction of the sealing ring of the kettle door, at the same time, also can prolong the service life of the sealing ring, the sealing ring is in use, should be regularly check, timely replacement, to ensure effective sealing kettle door.
3. 4. Keep the water clear
The autoclaved kettle body in addition to bear load caused by the formation of the steam pressure, load and bearing in the bearing rail pivot and the kettle body on the autoclave and the weight of the steam car and the weight of the products formed. The condensed water caused by the top and bottom temperature difference of formation stress, autoclave in the long-term stress of this cycle, easy to form the material fatigue, thus losing strength. At the same time, the corrosion of water and gas also easy to make the decrease of tensile strength. Therefore, we should promptly discharge the condensed water in the use process, especially in the initial stage of heating (30 ~60) a large amount of condensed water in the kettle, if not timely discharge, will be in the bottom to bottom lower aggregation, forming a low temperature region, the temperature difference increases (like a kettle body in 10 DEG C) may reach 60~70 degrees), the formation of the kettle on under too much stress
