Garbage feeding, prewarming and drying arrangement

Abstract

The present invention relates to a garbage feeding and pre-heating drying device, and belongs to the field of the biomass and renewable energy utilization devices, and comprises a garbage funnel, a material pushing device and a drying bed; wherein, the material pushing device is arranged above the drying bed. The garbage feeding and pre-heating drying device is distributed in one level or two levels; when the device is distributed in two levels, a stage-typed arrangement is formed between the front level and the back level; each level of the device comprises a material pushing device and a drying bed, and the drying bed is of a fixed type; each level of the material pushing device consists of a sliding-block guide-rail reciprocating mechanism, a connection box and a material pushing rod; the material pushing rod is hinged with the sliding block, and the material pushing rod is provided with a reversed-triangle fin. When the flat size of the drying bed is too large, two or more material pushing material devices can be arranged in parallelism. The drying device of the present invention has the advantages that with the material pushing rod, the garbage can be smoothly proceeded on the drying bed, thereby being uneasy to cause the squeezing; the height different exists between the drying bed and the material pushing device, so that the garbage falls down during the proceeding process, thereby realizing the effect of loosening the garbage, therefore, the garbage is dried more uniformly.

Description

technical field [0001] The invention relates to a garbage feeding and preheating drying device, which belongs to the field of biomass energy and renewable energy utilization equipment. Background technique [0002] In the process of waste incineration, especially the incineration process of circulating fluidized bed waste incinerator, the stable feeding of waste and the moisture content of waste have an important impact on its incineration stability and burnout, which also affects the performance of waste incineration. Cleanliness. [0003] Existing waste incinerators have a variety of waste feeding methods, such as belt feeding, drum feeding, chain plate feeding, water-cooled jacket feeding, etc. These feeding methods are usually used to transport waste from the waste pool to incineration Furnaces have their pros and cons. For high-moisture waste, most waste incineration plants do not have a separate pre-drying device. On the one hand, the leachate is partially separated ...

Problems solved by technology

However, in the application, it is found that the device still needs further improvement. For example, relying only on the advancement of the slider may cause the agglomeration or extrusion of garbage at a certain feeding point; the setting of the primary feeding and drying device, When the garbage feeding process is long, the uniformity of drying inside the garbage is not enough
