Autoclave for maintenance

Abstract

The invention relates to the field of forming product processing equipment, particularly discloses an autoclave for curing. The autoclave comprises an autoclave body and a support, wherein exhaust pipes are arranged on the support, and nozzles are arranged on the exhaust pipes; a gas storage tank is arranged on the support, an air inlet is formed in the gas storage tank, and a one-way valve is installed on the air inlet; the exhaust pipes are connected with the gas storage tank, wherein slow-release mechanisms are arranged at joints between the exhaust pipes and the gas storage tank; the slow-release mechanisms comprise air cylinders made of flexible material, one ends of the air cylinders are installed on the air storage tank, air outlets are formed in the air storage tank, and the air outlets communicates with the air cylinders; open rings are arranged at the ends of the air cylinders, multiple connecting rods are uniformly distributed in the circumferential direction of the openingrings, one ends of the connecting rods are hinged to the open rings, free ends of all the connecting rods are jointly hinged to pull rods, and the pull rods are parallel to the axes of the air cylinders; and baffles are connected to the ends, away from the connecting rods, of the pull rods. The autoclave has the advantages that cracks of aerated concrete during autoclaved curing are avoided, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of molding product processing equipment. Background technique [0002] "Autoclaved aerated concrete block" is made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) Aerated concrete is made by adding water and stirring, and then the pores are formed by chemical reaction, and the porous silicate product is made through pouring molding, pre-curing cutting, autoclaving curing and other processes. Autoclaved aerated concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, can be nailed, sawed, planed, and has a certain earthquake resistance. It is a new type of wall that turns waste into treasure. body material. [0003] Autoclave curing, that is, put the aerated concrete into the autoclave, and then inject high-temperature and high-pressure steam, and perform high-temperature and high-pressure curing on the product according to t...

AI Technical Summary

Problems solved by technology

[0004] The existing autoclaved curing process has the following defects or deficiencies: at the end of the autoclaved curing, the temperature in the kettle is about 100°C, and there is a large amount of water vapor. If the kettle door is opened immediately to quickly discharge the heat in the kettle, the cement in the kettle will The temperature of the product will also drop sharply, and the temperature is very uneven

At the same time, it will cause the edge and surface moisture of cement products to volatilize rapidly. Under the joint action of temperature stress and dry shrinkage stress, cement products are prone to produce small cracks or cracks, which will affect the strength and performance of the products, and even cause a large amount of waste products; and if Taking the method of slowly opening the kettle door to gradually reduce the temperature in the kettle or closing the kettle door to cool down naturally will greatly prolong the operation cycle of the autoclave and reduce production efficiency. Moreover, if the temperature and humidity in the autoclave are not properly controlled, the cement Products still have the possibility of cracking
