Automatic control system for steam curing of concrete precast pile

Abstract

The invention discloses an automatic control system for the steam curing of concrete precast piles, which comprises a group of steam curing tanks, a pipeline system, an induced draft fan, a steam distribution cylinder, an inverted steam distribution cylinder and a PLC (Programmable Logic Controller) control system, wherein the steam distribution cylinder and the inverted steam distribution cylinder are both connected with the group of the steam curing tanks through a group of opening control valves; the induced draft fan is connected with the group of steam curing tanks through a pneumatic butterfly valve; an electro connecting pressure gauge is arranged between the inverted steam distribution cylinder and an inverted steam electric gate valve; a temperature measuring unit is arranged in each steam curing tank; and the electro connecting pressure gauge, the temperature measuring unit, the pneumatic butterfly valve, the inverted steam electric gate valve, the opening control valves and the induced draft fan are all connected with the PLC control system. Through the invention, one or more steam curing tanks can be controlled independently and accurately, the quality of the concrete precast piles and the working efficiency of the steam curing tanks are improved, and meanwhile, steam generated by a boiler is reasonably and effectively used, so that the steam waste is avoided, residual steam exhausted from a still kettle is fully utilized, and a remarkable energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the field of steam curing for producing concrete prefabricated piles, in particular to an automatic control system for steam curing of concrete prefabricated piles. Background technique [0002] The steam curing process is an indispensable part of the production of concrete prefabricated piles. The gas supply system of the existing steam curing pools is all manually operated. The operators need to constantly observe the data displayed by the temperature gauge, pressure gauge, etc. Manually adjust the air supply status of the steam curing pool. This steam curing method for concrete prefabricated piles is labor-intensive for operators. The gas supply in the existing steam curing tank has no automatic adjustment function, and the steam curing process requires that the temperature in the steam curing tank needs to change with time. Therefore, the temperature in the steam curing tank cannot be adjusted accurately, which affects the ...
