Energy-saving waste scrap iron and waste plastic mixer

Abstract

The invention relates to an energy-saving waste scrap iron and waste plastic mixer. The energy-saving waste scrap iron and waste plastic mixer comprises a rack, a fusion box, a forming device, a spiral conveying device, a discharging and conveying device, a cutting and smashing device and a stirring and mixing device, wherein the discharging and conveying device consists of a discharging hopper, friction wheel sets, belt wheels I, upper belts and a motor A; the friction wheel sets are installed on the upper end of the discharging hopper; the cutting and smashing device consists of a motor B, a transmission, an eccentric wheel, a connecting rod, a cutter bit and a cutting base, wherein two sides of the cutting base are symmetrically provided with chutes; the stirring and mixing device consists of a mixing cavity, a first rotary shaft, a belt wheel II, a lower belt, a dual-output motor and a fixing base, wherein the left end of a first rotary shaft is provided with a stirring blade, and the right end of the first rotary shaft is fixedly connected with a screw rod; the screw rod is provided with a drive base. According to the mixer, the problems of difficulty in preparation of mixed materials of waste scrap iron and waste plastics, low material binding rate, difficulty in forming and the like.

Description

technical field [0001] The invention relates to the technical field of design of production equipment for scrap iron chips and waste plastic mixed materials, in particular to an energy-saving scrap iron scrap and waste plastic mixer. Background technique [0002] The recycling and reuse of scrap iron scraps and waste plastics has always been one of the research contents of green remanufacturing. There are many scrap iron scraps produced in machining workshops, and the shapes of scrap iron scraps produced by workpieces of different materials are also different. Small machinery processing enterprises will choose scrap iron scraps stored in the open air. After the scrap iron scraps get wet, the mixed water and other lubricating grease and oil will pollute the molten metal. Vaporizable materials such as mixed water and other lubricating grease will expand rapidly in the furnace due to the bursting effect, and should not be added to the furnace. Waste plastics are usually dispos...

[0002] The recycling and reuse of scrap iron scraps and waste plastics has always been one of the research contents of green remanufacturing. There are many scrap iron scraps produced in machining workshops, and the shapes of scrap iron scraps produced by workpieces of different materials are also different. Small machinery processing enterprises will choose scrap iron scraps stored in the open air. After the scrap iron scraps get wet, the mixed water and other lubricating grease and oil will pollute the molten metal. Vaporizable materials such as mixed water and other lubricating grease will expand rapidly in the furnace due to the bursting effect, and it is not suitable to add them to the furnace

For waste plastics, they are usually disposed of by landfill or incineration. Incineration will produce a large amount of toxic gases and cause secondary pollution; landfill will take up a large space; plastics will take more than a hundred years to degrade naturally; precipitation of additives will pollute soil and groundwater, etc.

In addition, due to different materials, scrap iron scraps and waste plastics have different shapes. Different types of scrap iron scraps and waste plastics need to be sorted and recycled, and then the recovered waste materials are melted into molten iron or liquid plastics, and then molded and casted, especially for The remelting of scrap iron chips not only requires a large amount of electric energy, but also the quality of recast blanks is low

The existing mixed materials of scrap iron scraps and waste plastics have problems such as difficult preparation, low bonding rate, and difficulty in molding. There is also a lack of devices on the machine that help to realize the function of cutting and crushing scrap iron scraps, and some mixers also lack devices that help to realize the function of rotating the first rotating shaft and performing reciprocating motion, which cannot make scrap iron powder and plastics Therefore, it is necessary to provide an energy-saving scrap iron scrap and waste plastic mixer with simple structure, fast and convenient movement, economical and practical
