Description

Technical Field

[0001] The utility model relates to the technical field of concrete slab production, in particular to an autoclave for producing autoclaved aerated concrete slabs. Background Art

[0002] Autoclave, also known as steam curing autoclave or pressure autoclave, is a large pressure vessel with a large volume and heavy weight. Autoclave has a wide range of uses and is widely used in the autoclave curing process of building materials such as aerated concrete blocks, concrete pipe piles, lime sand bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, and high-strength gypsum.

[0003] The patent application number CN219618111U discloses an autoclave for producing autoclaved aerated concrete blocks. The threaded rod is driven by a servo motor to drive the sealing plate to move on the inner wall of the water tank, so that the sealing plate squeezes the water source inside the water tank to the inner wall of the water pipe, and the water source inside the water pipe is discharged by the nozzle. The valve is moved by the rotation of the threaded rod, so that the nozzle sprays the concrete blocks on the placement plate during the removal process, thereby achieving the effect of cooling and removing the concrete blocks more conveniently.

[0004] However, in actual use, the following problems still exist: the water sprayed out for cooling is not easy to be recovered, which will cause great waste of water resources and is not environmentally friendly. In addition, the internal placement plate is still of the traditional structure and lacks an isolation structure. The plates are still stacked together when placed, with almost no gaps between them. As a result, the autoclaving effect of the bonding part is not good during the subsequent autoclaving work. Moreover, after the subsequent autoclaving is completed, the cooling effect of the bonding end is also slow. After the external cooling, the temperature of the bonding end is still high. At this time, when carrying it out of the kettle, it is easy to scald the operator, causing a dangerous situation. Utility Model Content

[0005] The utility model aims to solve the problems in the above background technology that the spraying heat dissipation causes water waste, and the plate body lacks an isolation structure when placed, which affects the autoclaving effect and the subsequent heat dissipation effect is not good.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an autoclave for producing autoclaved aerated concrete panels, comprising an autoclave body, a support base plate being bolted to the lower end of the autoclave body, track supports being slidably installed on the front and rear sides of the upper end of the support base plate, a support assembly being slidably installed inside the autoclave body, an air inlet pipe being connected to the front side of the upper end of the autoclave body, an arc-shaped pipe being welded and installed on the right side of the outer end of the autoclave body, a sleeve being installed on the front end flange of the arc-shaped pipe, a connecting pipe being threadedly installed on the front end of the sleeve, a heat exchange pipe being welded and installed on the right side of the outer end of the sleeve, a collecting pipe being welded and installed on the lower end of the connecting pipe, an exhaust pipe being welded and installed on the upper middle part of the connecting pipe, and a water collecting tank being connected to the lower end of the collecting pipe.

[0008] Preferably, a track is provided at the lower end of the interior of the autoclave body, and spray plates are symmetrically provided inside the autoclave body, and nozzles are provided on the inner sides of the spray plates.

[0009] Preferably, the front and rear ends of the support base plate are both provided with slide grooves, and the inner diameter of the slide grooves is matched with the outer diameter of the lower end of the track support.

[0010] Preferably, a threaded rod is threadedly installed in the middle of the lower end of the track support, and two feed tracks are welded and installed on the left and right sides of the upper end of the track support. The spacing between the feed tracks is the same as the height and spacing of the tracks inside the autoclave body.
