An autoclave transition device and its transition method

Abstract

The invention discloses a transition device for a steam-pressing trolley. The transition device comprises a transition trolley and a positioning block. A transition method for the steam-pressing trolley comprises the following steps that when the transition trolley is between any two autoclaves, the position of the transition trolley is an initial position; after an autoclave door of a certain autoclave is opened, an electric signal is sent out to a PLC (programmable logic controller) by a position sensor arranged on the autoclave door, and a motion command is sent to a speed reducer after the electric signal is received by the PLC; when a positioning air cylinder induces that a fourth proximity switch at the maximum stroke stops running, an inductive signal is received by a first electromagnetic valve for controlling a turnover air cylinder; finally, after transition is ended, the transition trolley runs according to a reverse direction described by a program until the transition trolley returns to the initial position and stops. According to the transition device for the steam-pressing trolley and the transition method for the steam-pressing trolley, disclosed by the invention, the defect of manual operation is remedied; transition tracks are provided for the steam-pressing trolley; the accurate butt joint of inner and outer tracks of the autoclaves is realized; the steam-pressing trolley can conveniently enter the autoclaves; the manual labor intensity is reduced; the production efficiency is increased.

Description

technical field [0001] In the field of industrial production of building materials, the invention specifically relates to an autoclave transition device and a transition method thereof, which are applied to the production of aerated concrete aerated bricks. Background technique [0002] Autoclave, also known as steam-cured kettle or autoclave, is a large pressure vessel with bulky volume and heavy weight. Autoclave has a wide range of uses, and is widely used in aerated concrete blocks, concrete pipe piles, lime sand Autoclaved curing of building materials such as bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, high-strength gypsum, etc., completes the hydrothermal reaction of Cao-SiO2-H2O in the kettle. Autoclaved trolley, also known as autoclaved car, is a special transport vehicle in the production process of aerated concrete. It adapts to the high temperature and high pressure autoclaved env...

AI Technical Summary

Problems solved by technology

At present, most manufacturers of aerated concrete and aerated bricks in China are still in the manual operation stage for the transition process of the autoclaved car in the aerated line. The autoclaved car is made to enter the inner track of the autoclave from the outer track of the autoclave by manpower. High strength, low production efficiency, high cost, not conducive to industrial production
