Description

Technical Field

[0001] The utility model belongs to the technical field of garbage pretreatment, and in particular relates to a superimposed elastic energy storage roller press. Background Art

[0002] All solid waste treatment industries are facing the problem of pre-treatment of wet garbage generated after the current urban garbage classification. Some wet garbage, such as kitchen waste, catering waste, and waste watermelon, usually contain a large amount of free water and are very slippery. Most treatment processes require the pre-removal of free water from the wet garbage or the pre-treatment of the wet garbage by breaking the wall to meet the requirements of subsequent treatment processes. The plate and frame filter press commonly used in the industry is usually not suitable for materials such as melons, fruits and vegetables, and kitchen waste, and has low continuous production capacity and efficiency; the screw press is easy to clog, and when encountering extremely slippery materials, the pressure in the screen cylinder of the screw press is very likely to be unstable, resulting in difficulty in starting pressure and constant stirring of water; the hammer crusher consumes a lot of energy and makes a lot of noise.
