Description

Trash dehydrator

The present invention compresses water containing waste such as sludge, livestock waste, papermaking waste, primary scum of a sewage treatment plant, vegetable and the like, generated in various wastewater or sewage treatment processes, And to a waste dewatering device capable of easily reducing incineration and burial treatment of waste, simplifying handling, and maintaining a hygienic state satisfactorily.

Generally, there are a method of disposing the collected garbage in a specific place and an incineration method of disposing the garbage.

However, in the case of the landfill method, there are considerable restrictions on the selection of the landfill site and the landfill site because it causes a bad odor in the vicinity and causes pollution of the atmosphere and water due to leachate. In the case of the incineration method, There is a technical difficulty due to the selection and incineration of incineration sites.

Also, in the case of the landfill method, the recycling of the waste is not possible at all. In the case of the incineration method, the pretreatment process of drying the waste before the incineration is performed, and the soot generated in the combustion causes the air pollution.

In order to solve the above-mentioned problems, recently, prior to filling and incineration of water-containing waste, it has been proposed to use a method such as sedimentation concentration, belt press, filter press, The dehydration of the contained water reduces the volume and weight of the garbage so that landfill and incineration treatments are available.

However, such a method is disadvantageous in that the mechanical structure is complicated, causing a rise in cost at the time of manufacture, a dehydration effect is less than the scale, and the operation is frequently stopped due to frequent failures.

In addition, since the breakage of the belt as the filter cloth is frequent, it often fails to exhibit its function, and there is a problem that excessive manpower required for the operation of the machine and excessive cost of the facility management are incurred.
