Intelligent control device for concrete product high-pressure autoclave

Abstract

The invention relates to an intelligent control device for a concrete product high-pressure autoclave. The intelligent control device comprises a autoclave door opening and closing unit and a pressurecontrol unit, wherein the autoclave door opening and closing unit comprises a lever part connected with an autoclave door, the lever part is arranged in the vertical direction, the lever part on theautoclave door is hinged to a hinge frame, and the upper end of the lever part is connected with a linear driving mechanism through a connecting piece; and the linear driving mechanism is arranged atthe top of an autoclave body, and is suitable for adjusting the rotating angle of the lever part along the hinge frame through the connecting piece so as to open or close the autoclave door. Accordingto the device, automatic control of opening and closing of the autoclave door is realized, automatic adjustment can be realized according to the steam quantity in the autoclave, the steam inlet quantity is further controlled, in addition, the autoclave door can automatically stay per stages in the opening process, so that the problem that product cracks are caused due to the fact that pressure and temperature inside the autoclave body are suddenly reduced in the case that the autoclave door is directly opened is avoided, the whole curing work of the high-pressure autoclave basically does notneed manual direct participation, so that the labor intensity is greatly reduced, and the curing efficiency and the curing quality of concrete products are improved.

[0002] At present, concrete products need to use autoclave for steam curing. During the curing process, the autoclave door switch mainly relies on manual participation. It is necessary to manually judge whether there is residual steam and residual pressure in the autoclave. The steam delivery in the autoclave generally requires manual rotation. Steam cut-off valve control, the maintenance process of concrete products mainly depends on manually adjusting the steam stop valve according to the data feedback of the steam pressure gauge and temperature gauge of the autoclave, so as to meet the maintenance process of concrete products at different stages, and the experience and professionalism of the operators The requirements are high, but manual operation is prone to errors. Too fast or too slow pressure rise and fall in the autoclave or inaccurate time control will affect the curing effect of concrete products and affect product quality, such as product ring cracks, longitudinal cracks and other problems; in addition, In the actual construction process, due to the insufficient sense of responsibility of the operators, the operation cannot be carried out completely in accordance with the operating specifications. Often, the steam is delivered when the kettle door is not closed properly, or the kettle is opened when there is still residual steam pressure (the pressure gauge has not been reset to zero). The autoclave door is likely to cause an explosion in the autoclave, and the autoclave door and pipe piles will rush out of the autoclave for tens of meters, causing major safety accidents. Such accidents in autoclaves across the country occur from time to time, causing serious consequences

Moreover, most of the existing autoclaves have side-opening doors. The operator rotates the kettle door by shaking the handle to make the kettle door gear ring and the kettle body gear gear stagger, and then manually pulls the kettle door away from the kettle body (pulls out from the gap between the kettle body gear gear and ), and rotated to the outside of the kettle body, but because of the high ambient temperature around the kettle body and the large fog (residual steam, waste heat), the operator's vision is poor, and the kettle door shaft collision problem often occurs when the kettle door is manually pushed and pulled, which is easy to cause a break There is a great potential safety hazard; even if the new autoclave chooses the upper door opening device, the specific position of the kettle door during the opening process mainly depends on manual control, and the opening process of the kettle door will affect the inside of the autoclave. The cooling speed of concrete products, the manual control of the opening position of the kettle door is not accurate enough, which affects the product quality
