Cleaning device and method for fragments with grease

Abstract

The invention discloses a cleaning device and a cleaning method for fragments with grease. The cleaning device comprises a rinsing tank, wherein a grease removing mechanism is arranged on the upper part of the rinsing tank; the grease removing mechanism comprises a plurality of tensioning wheels, an oil absorbing belt encircling the tensioning wheels, a power mechanism connected with the tensioning wheels, a fragment scraping plate and an oil absorbing tank; the oil absorbing belt consists of a stress layer and an oil absorbing layer; the oil absorbing belt is provided with an oil absorbing part which stretches below the level of the rinsing tank; at least one of the tensioning wheels comprises a group of oil extrusion tensioning wheels; each group of oil extrusion tensioning wheels comprises two oil extrusion tensioning wheels; an oil extrusion gap which is smaller than the thickness of the oil absorbing belt is formed between the two oil extrusion tensioning wheels; the oil absorbing belt passes the oil extrusion gap to form an oil extrusion part; and the fragment scraping plate is arranged on the outer side of the oil absorbing belt. The grease in the fragments can be effectively removed by the cleaning device for fragments with grease. The cleaning device has the advantages that the production efficiency is high; the grease separating effect is good; the shapes of the fragments are maintained as much as possible in the cleaning process; the degree of automation is high and the like.

Description

technical field [0001] The invention relates to a material cleaning device and method, in particular to a cleaning device and method with grease fragments. Background technique [0002] In many occasions, it is necessary to separate the grease attached to the debris material; for example, in the field of plastic recycling and recycling, the recycling of plastic with grease occupies a large part. Common materials to be cleaned with grease include disposable lunch boxes, used oil tanks, oil pots, etc. The recovery process of oily materials often includes crushing and cleaning. Among them, the cleaning of broken oily pieces is a technical difficulty in production. The reason is that, on the one hand, many materials are lipophilic and difficult to separate. On the other hand, the density of many materials is lower than that of water like grease, so the debris to be cleaned and the grease float on the water surface during the cleaning process, making it difficult to separate the...

The recovery process of oily materials often includes crushing and cleaning. Among them, the cleaning of broken oily pieces is a technical difficulty in production. The reason is that, on the one hand, many materials are lipophilic and difficult to separate. On the other hand, the density of many materials is lower than that of water like grease, so the debris to be cleaned and the grease float on the water surface during the cleaning process, making it difficult to separate the two

[0003] The cleaning method with greasy debris in the prior art is by: (1) adopt additive (such as detergent, alkali, surfactant etc.) machine type to clean, and the deficiency that it exists is that cost rises, and brings to the sewage treatment after cleaning simultaneously (2) cleaning by various functional rubbing machines, for example, the "multifunctional rubbing and separating device for cleaning waste plastics" disclosed by the invention patent of CN103112102B with the authorized announcement number, but this method is not suitable for some fragile materials ( For example, foamed lunch boxes, beverage cups, etc.) when the cleaning materials pass through the rubbing machine, the shape of the fragments will be destroyed, and the fragments will be broken into fine pieces, which will bring difficulties to the next step of separation.

[0004] In addition, the utility model patent with the authorized notification number CN2097827U discloses an "oil slick recovery and separation device", which can remove slick oil in wastewater, but this oil slick recovery and separation device is not suitable for cleaning with grease debris, because The cleaning of oily debris not only requires the removal of oil slicks, but also the separation of debris from oil slicks and other impurities
