Embodiment Construction

[0010] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , the present invention comprises the fire grate surface 6 that is made of 3-10 drums 1, and general situation is advisable with 4-6, and the included angle of fire grate surface 6 and horizontal plane is 10-60 °, and the practical example selects 30 ° Included angle, each drum 1 is provided with an air outlet, and between adjacent drums 1, there is a slag stopper 2 for "shoveling" the garbage to the next drum 1. The slag stopper 2 is a hollow structure, and the middle is opened Cooling media such as air or water, the lower end of the slag stopper 2 is provided with a partition 7, which divides the space below each drum 1 into individual chambers, and each chamber is provided with a grate plate 4 for cleaning after rotation. Out of the funnel-shaped container 8 of the ash.

Abstract

The invention discloses a scale-type fire bar of a garbage burning roller; a fire bar surface with an inclined angle of 10 to 60 degrees is built by a plurality of rollers; besides, certain fire bar sheets which are axially arranged and rotatable are arranged on the rollers; the fire bar sheets are crossed into scale type. In order to prevent blocking and plugging caused by the deformation of each fire bar sheet due to being heated, the two sides of the fire bar surface are provided with blocking-proof salients. Dirt traps are arranged among the rollers for preventing leakage and leading transportation to be more spontaneous.

Description

technical field [0001] The invention belongs to the technical field of combustion, and in particular relates to a scale-type rubbish incineration drum grate. Background technique [0002] Waste incineration technology can reduce the weight of domestic waste by 80% and volume by more than 90%. Therefore, waste incineration is a promising and economical treatment method, and mechanical grate combustion is generally used. Most of the traditional fire grates are composed of a plurality of plate grates arranged on the grate. Under the action of external traction or thrust, the grate slides on the grate to continuously send fuel into the furnace. The problems of this kind of grate are: the frictional resistance of the grate movement is large, the load of the traction or pushing device is large, and the grate made of solid steel bars is easy to deform and fuse, so failures often occur during operation, making the grate The boiler does not operate normally, is less reliable and is ...
