Abstract
The utility model discloses an incinerator grate mechanism of a marine incinerator. The incinerator grate mechanism of the marine incinerator comprises an incinerator grate body and an incinerator grate base disc, and further comprises movable incinerator grates and a movable incinerator grate air outlet channel formed below the movable incinerator grates. Transmission assemblies used for transmitting movement of the incinerator grate body are arranged inside the incinerator grate base disc. The three transmission assemblies are connected with a rotary shaft of an external motor through a screw mechanism. Each transmission assembly comprises a cam and a transmission shaft used for transmitting the cam. The number of the movable incinerator grates is four, and the four movable incinerator grates are symmetrically arranged on the surface of the incinerator grate base disc. One end of each movable incinerator grate makes contact with the corresponding cam inside the incinerator grate base disc; the other end of each movable incinerator grate makes contact with the corresponding arc-shaped face of the incinerator grate body. When the incinerator grate mechanism of the marine incinerator works, external air passes through the air outlet channel, enters the incinerator grate mechanism and then enters a furnace along an incinerator grate air outlet to supply enough oxygen for burning of garbage; meanwhile, the external motor drives the cams to rotate, the movable incinerator grates are made to periodically swing at a certain angle, then the garbage on the incinerator grate body is turned over to be heated and burnt completely, and burning efficiency is improved.

Background technology
Foreign-going ship can produce a large amount of rubbish in the process of transporting cargo.In order to process the combustible waste material on ship, most transport by sea boats and ships have all been equipped with incinerator as refuse treatment plant.Ship garbage is carried out to burning disposal, subtract capacity large, can improve the effective rate of utilization in hull space, improve hygienic conditions, and the residue in afterburnt has fewer environmental impacts.The structure of marine incinerator has direct impact to the combustion efficiency of rubbish.Wherein grate body is the key equipment of incinerator, and whether fully combustion effects is larger to rubbish for the level of its mechanism design.
Be subject to the physical dimension restriction of marine incinerator, existing fire grate mechanism of marine incinerator is mainly fixed, and rubbish can not get stirring on fire grate, cannot fully be heated, and bed of material bottom can not get enough ventilations, burn insufficient, slag is more.If use sliding grate, not only fire grate equipment is more, and mechanism is comparatively complicated, and processes and safeguard all comparatively difficult.
Summary of the invention
The purpose of this utility model is that rubbish that marine incinerator fixed type grate causes cannot stir and bed of material bottom can not get enough problems such as ventilation in order to solve, and a kind of fire grate mechanism of marine incinerator is provided.
The utility model is achieved through the following technical solutions:
A fire grate mechanism of marine incinerator, comprises air-out passage, fire grate air outlet, the ash hole of fire grate body, fire grate botton plate, fire grate botton plate;
Also comprise moving fire grate, be arranged on the moving fire grate air-out passage that moves fire grate below; Described fire grate botton plate inside is provided with the transmission component for drive fire grate motion; These 3 groups of transmission components are connected with external motor rotating shaft by a screw mechanism;
Every group of transmission component comprises cam and for the power transmission shaft of driving cam;
Described moving fire grate has 4, is arranged symmetrically in the surface of fire grate botton plate;
One end of moving fire grate contacts with the cam of fire grate botton plate inside, and the other end contacts with the arcwall face of fire grate body;
The width of moving fire grate air-out passage is 2/5～1/3 of fire grate air outlet length.
On the air-out passage of fire grate botton plate, moving fire grate air-out passage, all have and be uniformly-spaced furnished with air outlet, its air outlet width is 2 times～2.5 times of fire grate air outlet width.
The cross section of moving fire grate is folding rule shape.
The Space Cross Section of moving fire grate below is inverted trapezoidal.
The length of fire grate air outlet accounts for 6/50～7/50 of fire grate botton plate diameter, and its width is 2mm～5mm.
Fire grate botton plate is flattened cylindrical body structure.
The utility model has the following advantages compared with prior art:
Moving fire grate swings by transmission component property performance period, and the rubbish on fire grate is stirred fully in combustion process, has solved the problem inhomogeneous, incomplete combustion of being heated.
The burning that is set to rubbish of air-out passage provides sufficient air, has improved combustion conditions, can reduce largely the discharge of pollutant;
Moving fire grate is driven by transmission components such as cam and power transmission shafts, is easy to manufacture maintenance and stable.
This grate body process structure is simple, is easy to manufacture, and is also beneficial to maintenance.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is more specifically described in detail.
Embodiment
As shown in Figure 1, 2, 3.The utility model fire grate mechanism of marine incinerator, comprises air-out passage 4, fire grate air outlet 1, the ash hole 9 of fire grate body 10, fire grate botton plate 3, fire grate botton plate 3;
Also comprise moving fire grate 2, be arranged on the moving fire grate air-out passage 5 that moves fire grate 2 belows; Described fire grate botton plate 3 inside are provided with 3 groups for the transmission component of drive fire grate 2 motions; These 3 groups of transmission components are connected with external motor rotating shaft by a screw mechanism;
Every group of transmission component comprises cam 7 and for the power transmission shaft 6 of driving cam 7;
Described moving fire grate 2 has 4, is arranged symmetrically in the surface of fire grate botton plate 3;
One end of moving fire grate 2 contacts with the cam 7 of fire grate botton plate 3 inside, and the other end contacts with the arcwall face 8 of fire grate body 10;
The width of moving fire grate air-out passage 5 is 2/5～1/3 of fire grate air outlet 1 length, provides wind-force, for enough air are supplied with in the burning of rubbish on fire grate by outside blower fan.
On the air-out passage 4 of fire grate botton plate 3, moving fire grate air-out passage 5, all have and be uniformly-spaced furnished with air outlet, its air outlet width is 2 times～2.5 times of fire grate air outlet 1 width.
