Abstract

The utility model relates to a chain type boiler capable of burning chaffs after improved, which is a boiler for fuels to burn on a rotary chain type fire grate. One side of a viewing window revolving door is provided with an inserting plate in the feed hopper of the boiler. The upper side of the inserting plate hooks the edge of the inlet of the feed hopper and the lower section stretches out of the outlet of the feed hopper and directly butts the fire grate. The extension line of the inserting plate intersects a supporting plate to cut off the passage for chaffs to enter a void between a chain wheel and the supporting plate. Through the improvement, when chaffs fall on the fire grate from the feed hopper, the chaffs can only get to the fire grate above the supporting plate through the guiding and the limitation of the inserting plate. The chaffs leaking from the gaps of the fire grate only can fall on the supporting plate and the temperature of the position is high and the oxygen is adequate. Thereby, the chaffs quickly burn into ashes. Thus, the phenomenon that the chain is propped to be broken off because of the carbonized and coked blocks due to sulky burning because the chaffs leak to the void between the chain wheel and the supporting plate. The utility model causes the chain type boilers burning coals to be changed into the chain type boilers capable of burning chaffs.

Description

A kind of through transforming the chain type boiler that can burn the chaff shell

Technical field:

The utility model relates to the boiler that fuel burns on the chain type fire grate of rotation.

Background technology:

Along with the utilization that replaces waste agronomic crop owing to tightly disappearing of coal resource, increasing coal-burning boiler changes burning chaff shell.Yet directly the chain type boiler with fire coal changes burning chaff shell, the problem that the frequent chain that the walking of drive fire grate takes place ruptures.This be because, referring to Fig. 1, there is the revolving door 6 of an observation window (being commonly called as the lunar crust door) lower end of the feed hopper 1 of this boiler, the setting of revolving door makes the outlet of feed hopper vertically elongated along body of heater; Under the outlet of feed hopper 1, have a space 4 between sprocket wheel 2 and the supporting plate 3, be installed between each the piece fire grate 5 on the chain and have the air intake gap.When the chaff shell when feed hopper 1 drops on the fire grate 5, have some gap locations between fire grate and drain to the described space 4, because this locates relative cold and oxygen deficient, the chaff shell of plug in the space smoulders gradually that the carbonization coking becomes piece, increasing coke button finally makes it fracture gradually with chain jack-up.And when burning coal, because coal coking temperature is much higher, the coal grain that leaks in the space can coking not become piece, so space 4 does not form obstruction.Therefore, if coal-fired chain type boiler is not added transformation, directly change with this boiler and burn the chaff shell, production just is difficult to normal.

Summary of the invention:

The purpose of this utility model, be that coal-fired chain type boiler is transformed, make through the chaff shell that hopper enters and avoid space between hopper outlet lower sprocket and the supporting plate, make the chain fracture, thereby still can normally use after coal-burning boiler being changed burn the chaff shell in order to avoid form coke button at this place.

Realize that the above-mentioned purpose technical scheme is, in revolving door one side one plate is set in the feed hopper of boiler, the edge of feed hopper import is caught in the top of plate, and fire grate is directed reach in the outlet that hypomere stretches out feed hopper, its extended line and supporting plate intersect, and will block towards the passage in space between sprocket wheel and supporting plate.

By above-mentioned transformation, when the chaff shell descends to fire grate by feed hopper, under the guiding and restriction of plate, the chaff shell can only arrive on the fire grate above the supporting plate, the chaff shell that leaks down from the fire grate gap only can be fallen on the supporting plate, and temperature high oxygen abundance herein, the chaff shell immediately burns into ashes, after running up to certain thickness, the fire grate of being walked is shifted furnace bottom onto, the space of so just having avoided the chaff shell to drain between sprocket wheel and supporting plate takes place because of the carbonization coking of smouldering becomes piece to make chain be pushed up disconnected situation, the chain type boiler that burns coal can be changed burn the chaff shell.Because plate is not to be fixedly connected on feed hopper, so still can use observation window.

Description of drawings:

Fig. 1 is the partial sectional view of the boiler before transforming;

Fig. 2 is the partial sectional view of improved boiler.

The specific embodiment:

Referring to Fig. 2, improved chain type boiler comprises feed hopper 1, feed hopper is installed in each the piece fire grate 5 on the chain for 1 time, the sprocket wheel 2 of chain drive-belt, the supporting plate of under near the upper grate sprocket wheel 2, fixing 3, there is an observation window in the exit, lower end of described feed hopper 1, window is equipped with a revolving door 6, it is characterized in that, in feed hopper 1 in revolving door 6 one sides be provided with one with feed hopper 1 with wide plate 7, the last Edge Bend of this plate, collude edge in feed hopper 1 import, hypomere stretches out the outlet of feed hopper 1, perhaps hypomere is done bending slightly, sees double dot dash line.Stretch out the outlet of feed hopper 1, direct reach fire grate 5, the extended line that colludes the plate 7 on feed hopper 1 inlet edge should intersect with supporting plate 3, the process bending, the extended line of dogleg section will intersect with supporting plate 3, and the passage that the chaff shell is entered the space 4 between sprocket wheel 2 and the supporting plate 3 blocks.Consider beating of fire grate when walking,, should reserve the gap of about 10mm between plate 7 and the fire grate 5 for avoiding interfering, because of the direct of travel of fire grate towards Lu Tang, so this gap can not make the chaff shell enter space 4.

Claims
