Heating boiler for uniform heating based on programmable logic controller (PLC) control

Abstract

The invention discloses a heating boiler for uniform heating based on programmable logic controller (PLC) control. The heating boiler for uniform heating based on PLC control comprises a boiler body,a heating water tank, a combustion groove, a heat exchange chamber, an ash collecting tank, a combustor, a mixing blade and a PLC controller, wherein the heat exchange chamber is arranged on the bottom part of the boiler body; the ash collecting tank is placed under the heat exchange cavity; a heat exchange pipe is arranged above the ash collecting tank; a tap water inlet is formed in one end of the heat exchange pipe and stretches out of the outer side of the boiler body; the other end of the heat exchange pipe penetrates through a shell of the boiler body and communicates with a water inletpipe; the water inlet pipe is connected to one side of the heating water tank; a water outlet pipe is connected to the other side of the heating water tank; a first temperature sensor is arranged on the water outlet pipe; a second temperature sensor is inlaid to the upper end of the inner wall of the heating water tank; and by utilizing a temperature difference between the first temperature sensorand the second temperature sensor, the PLC controller controls a stirring motor to start, so that a water solution can be timely stirred uniformly, water is uniformly heated, automatic control is realized, and the manpower is saved.

Description

technical field [0001] The invention relates to a heating boiler, in particular to a PLC-based uniform heating heating boiler. Background technique [0002] A boiler is a mechanical device that uses heat from fuel or other energy sources to heat water into hot water or steam. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power plant, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred t...
