Abstract
The utility model discloses a vibrating grate, which comprises an air chest and a blowpipe mounted therein, wherein upper part of the air chest is provided connectedly with the grate via a corrugated cover; the air chest has a cylinder within, bottom of which is fixed and piston of which connects with the above grate via a piston rod, the cylinder body at one side of the piston connecting with a high pressure air source and a low pressure cavity via valves. By control the valves for communication of the cylinder body at one side of the piston with the high pressure air source or the low pressure cavity, reciprocating motion of the piston can be realized to drive the grate to vibrate upward and downward. An existent air source in a factory can be used as the high pressure air source can, so no motor or other individual power source is needed for vibration of the grate, thereby lowering both the cost and power consumption. In addition, the grate vibration frequency can be conveniently controlled by adjustment of the communication make-break frequency of the cylinder with the high pressure air source and the low pressure cavity through valve regulation.
Description
Technical field
The utility model relates to the fire grate of boiler, particularly a kind of vibrating-grate stoker.
Background technology
In the boiler, after the right material burning, can produce ashes, these ashes parts are taken away with high-temperature flue gas, and part directly drops on fire grate, the temperature of ashes is very high, fall the ashes on fire grate, drain as untimely, meeting combine with fire grate and corrode fire grate, fire grate is ruptured easily, thereby influence the service life of fire grate.In order to prevent that the high temperature ashes from accumulating on the fire grate and the corrosion fire grate can vibrate by fire grate and realize.Fig. 1 is existing a kind of vibrating-grate stoker, and it rotates by the driven by motor cam, periodically pushes the cam chair that is fixed on the fire grate by the line of apsides of cam, makes the fire grate up-down vibration.It periodically vibrates by fire grate, the ashes on the fire grate is trembled down, thus the protection fire grate.Yet this device needs the motor that the special driving cam rotates, and the fire grate of boiler is heavier, the higher-wattage motor-driven need be arranged, than power consumption.Simultaneously, motor is generally constant-seed motor, and it can not control the vibration frequency of fire grate as required.And if use variable-frequency motor, then it costs an arm and a leg.
Summary of the invention
The purpose of this utility model is to provide a kind of power saving and fire grate vibration frequency vibrating-grate stoker easy to adjust.
Vibrating-grate stoker of the present utility model, bellows are arranged and be loaded on its interior airduct, the top of bellows is connected with fire grate by corrugated cover, it is characterized in that: cylinder is arranged in the bellows, the bottom of cylinder is fixed, its piston links to each other with the fire grate of top by piston rod, and the cylinder block of piston one side connects high-pressure air source and low-pressure gas source by valve respectively.
Vibrating-grate stoker of the present utility model, piston links to each other with fire grate by piston rod, when by-pass valve control makes the cylinder of piston one side be communicated with high-pressure air source, motion drives the fire grate motion thereby high pressure gas is known from experience the promotion piston, and when by-pass valve control makes the cylinder of piston one side be communicated with low-pressure gas source, then owing to the effect of gravity, fire grate can counter motion.Be communicated with high-pressure air source and low-pressure gas source repeatedly by cylinder, can realize the reciprocating motion of piston in cylinder, thus pulling fire grate up-down vibration.High-pressure air source can directly be utilized the existing high-pressure air source of factory, and the vibration of fire grate need not used motor or other independent power sources, and the cost-effective while again can power saving.Simultaneously,, regulate the frequency of the switching of cylinder and high-pressure air source and low-pressure cavity, can realize control the vibration frequency of fire grate by by-pass valve control, very convenient.

The specific embodiment
Embodiment 1, and as Fig. 2, a kind of vibrating-grate stoker has bellows 1, and airduct 2 is housed in the bellows 1, and the top of bellows 1 is connected with fire grate 4 by corrugated cover 3, and corrugated cover 3 can be the ripple canvas shroud and also can be the corrugated metal cover.Cylinder 5 is positioned at bellows 1, and the bottom is fixed, and its piston links to each other with top fire grate 4 by piston rod 6, and the cylinder body of piston below connects high-pressure air source 8 by valve 7, connects low pressure cavity 10 by valve 9.
Piston connects fire grate 4 by piston rod 6, and when opening valve 7, during valve-off 9, when cylinder 5 only was communicated with high-pressure air source 8, cylinder 5 was communicated with a side air pressure with the high pressure origin and raises, and promoted piston and moved to opposite side, thereby move by piston rod pulling fire grate.When opening valve 9, and during valve-off 7, when cylinder communicated with low pressure cavity 10, this lateral pressure of cylinder reduced, and fire grate falls under the effect of gravity.It makes the air pressure change in the cylinder by the switching of by-pass valve control 7 and valve 9, and makes piston rod motion repeatedly in cylinder body, drives the fire grate up-down vibration.The high-pressure air source that is communicated with cylinder can directly be utilized the existing high-pressure air source of factory or workshop, need not use motor or other independent power sources, both cost-saving, power saving again.Simultaneously,, can control the vibration frequency of fire grate, thereby the control of the vibration frequency of fire grate is very convenient by the switching frequency of by-pass valve control 7 and valve 9.
Among the embodiment, valve 9 can not be connected with the low pressure cavity yet, and directly communicates with atmosphere.
Embodiment 2, and as Fig. 3, Fig. 4, a kind of vibrating-grate stoker has bellows 1, and airduct 2 is housed in the bellows 1, and the top of bellows 1 is connected with fire grate 4 by corrugated cover 3, and corrugated cover 3 can be the ripple canvas shroud and also can be the corrugated metal cover.Cylinder 5 is positioned at bellows 1, and the bottom is fixed, and its piston links to each other with top fire grate 4 by piston rod 6, between piston below and cylinder body spring 10 is installed, and the cylinder body of piston top connects high-pressure air source 8 by valve 7, is communicated with atmosphere by valve 9.
In the present embodiment, between piston below and the cylinder spring 13 is installed, more steady when it can make the up-down vibration of fire grate.
