Municipal waste recycling pretreatment device

Abstract

The invention discloses a municipal waste recycling pretreatment device, which comprises a pretreatment device, wherein the pretreatment device comprises a scattering box, the scattering box is internally provided with a sliding table in mirror image distribution, two ends of the scattering box are provided with first bearing holes distributed in an array mode, one side of the scattering box is provided with a scattering box supporting plate, the other side of the scattering box is provided with a scattering box supporting frame in mirror image distribution, the scattering box is internally provided with scattering rollers distributed in an array mode, one side of the scattering box is provided with a first servo motor for driving the scattering rollers to rotate, a uniform spreading box is further arranged below the scattering box, uniform spreading box supports distributed in an array mode are arranged below the uniform spreading box, a first conveying belt is arranged below the uniform spreading box supports, a cleaning treatment frame is arranged on the first conveying belt, and a second conveying belt is arranged below a briquetting mechanism. The municipal waste recycling pretreatment device is simple in structure, high in waste treatment efficiency, capable of effectively sorting useful iron metal in waste, beneficial to environmental protection, and capable of reducingsmoke dust generated by waste treatment, reducing harmful substances in the later period of waste treatment and reducing the labor intensity of operators at the same time.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a recycling pretreatment device for urban garbage. Background technique [0002] Municipal waste is a mixture of solid waste in cities, including industrial waste, construction waste and domestic waste. The quantity, nature and degree of environmental pollution of industrial wastes vary greatly, so they should be managed in a unified manner. According to different situations, each factory will place them in designated areas directly or after treatment to meet the discharge standards. Construction wastes are generally non-polluting solids. , can be disposed of by landfill. Household garbage is the solid waste produced by people in daily life. There are many types, including organic and inorganic substances, which should be classified, collected, transported and treated. Urban garbage includes: Garbage generated in the process of growing food. This kind of garbage is highly corr...

Problems solved by technology

This kind of garbage is generally disposed of by the construction unit itself, but there are also a considerable amount of construction waste entering the urban garbage, cleaning garbage: including waste in public garbage bins, cleaning materials in public places, waste after road damage, etc. , there are many ferrous metals that can be recycled. The existing method is manual selection and sorting. This method is not only inefficient, but also labor-intensive. Harmful gases in the garbage also threaten the health of the workers. In view of this situation, Now propose a kind of urban waste recycling pretreatment device
