The utility model content
The purpose of this utility model provides a kind of full-automatic warming stove, with the deficiency that overcomes existing warming stove complex structure, cost height and easily break down.
The purpose of this utility model is achieved through the following technical solutions:
A kind of full-automatic warming stove comprises body of heater, and the described upper of furnace body left side is provided with coal store, and the coal store top is provided with coal filling hole; Described upper of furnace body the right is provided with the combustion chamber, and top of combustion chamber is provided with chimney, is provided with inclined grate, horizontal fire grate and lighting-up tuyere in the described combustion chamber, and inclined grate is positioned at the top of horizontal fire grate, and lighting-up tuyere is positioned at the top of inclined grate; The bottom of described body of heater is provided with ash bucket and inlet air plenum, and inlet air plenum one side is provided with the air blast interface, and the air blast interface connects air blast; Described horizontal fire grate is connected with connecting rod, change the inclination angle of coal by reciprocating, realize the motion of coal, horizontal fire grate below entering after the burning on the inclined grate of coal above being positioned at, after the coal on the horizontal fire grate fully burns, survey the temperature of ashes by the temperature sensor that is located at the body of heater rear portion, after the temperature of ashes is lower than the temperature of setting, the proof burning fully, can discharge, by fire grate, reductor drives horizontal stove and is discharged into multiple running, simultaneously, drives inclined grate shake up and down by a small margin, coal ash is pushed away in following ash bucket, after ashes temperature that the temperature sensor at body of heater rear portion is surveyed is higher than the temperature of setting, prove that coal does not also have completing combustion, fire grate shuts down.After ashes were discharged, the coal on top fell within on the horizontal fire grate by deadweight.Running and so forth realizes automatic stoking, ash discharge.
The flow process of water: after water enters body of heater by water inlet, enter in the furnace sandwich through threeway and sparge pipe, the water in the furnace sandwich absorbs heat a back part from the discharge of top delivery port, and a part is absorbed heat after delivery port is discharged through intermediate course.
The control of leaving water temperature: the delivery port place is provided with the leaving water temperature sensor, and after the leaving water temperature of measuring was lower than the leaving water temperature of setting, the temperature controller control air blast that is connected with the leaving water temperature sensor was opened, toward the interior air-supply of stove; After the leaving water temperature of measuring was higher than the leaving water temperature of setting, temperature controller control air blast shut down.So repeatedly, realize the automatic control of leaving water temperature.
The bearing structure of body of heater: on the two panels of furnace sandwich, intermediate course,, be connected with reinforcing bar between nut and the nut by 100 millimeters of spacings WELD NUTS symmetrically.
The utility model beneficial effect is: pressure-bearing height, operating pressure are 0.25MPa, can satisfy the requirement of general industry and civilian heating, and be simple for structure; Ash discharge and leaving water temperature Automatic Control; Manufacturing cost has only the 20-50% of the manufacturing cost of other full-automatic boiler of present market; Sufficient combustion, boiler thermal output can reach more than 80%, and fume emission reaches environmental requirement; At the bottom of the fault rate, be convenient to maintenance.
