Description

The rotation refuse grinder

Technical field:

The utility model belongs to the treatment of urban garbage technical field, relates to a kind of urban waste disposal equipment, particularly relates to the rotation refuse grinder.

Background technology:

At present, there be more than 600 city in China, and produce quantity of refuse per year and reached 1.5 hundred million tons, and annual with 8%～10% speed increase.The treatment of urban garbage technology of being used widely in China mainly contains sanitary landfills, burning and compost.Because the fund and the technical problem of the middle samll cities and towns of China, it is to adopt traditional sanitary landfills that 83% garbage disposal is arranged, and has 13% garbage disposal to adopt the burning mode, and other has 4%, and what adopt is the processing mode of compost.The industrial treatment technology is adopted in garbage disposal in developed country more than 80%.Incineration treatment of garbage has following some distinguishing feature: (1) is reliable, can round-the-clock running; (2) processing speed is fast, and treating capacity is big; (3) volume reduction rate height after the waste incineration; (4) in the high temperature incineration process, a large amount of pathogen that rubbish carries are eliminated, and have improved the hygienic conditions in city.Along with the expansion of city size, the increase of urban population, China's land resource growing tension, a lot of cities are difficult to find suitable landfill place, thereby the ratio of employing incineration treatment of garbage mode will be more and more higher, has huge development prospect.

In municipal refuse industrial treatment technology, the quality of treatment effect depends on the performance for the treatment of apparatus.And the refuse breaking treatment facility then is one of capital equipment of municipal refuse industrial treatment.Through retrieval, find present open source literature and reported some refuse breaking treatment facilities.The LPF2 type refuse breaking screening integration apparatus of introducing as 2000 the 18th the 4th phases of volume of Chinese patent ZL94236749.9 and " environmental hygiene engineering " etc., the horizontal type structure equipment of forming by drive unit, rotation screen drum, rotor segment, screen drum scraper plate, feed inlet and outlet, rotating shaft and guard shield etc.The 2nd, the refuse breaking treatment facility that produces the LPF type from the SPC type of Japanese import and China is same type a equipment.Before and after two kinds of refuse breaking treatment facilities be both the rotation push-press type, its difference is that rotating shaft and screen drum axis are whether on same horizontal line.Easy obstruction on same horizontal line, the blockage on the not same horizontal line improves.The disintegrating machine type that automatic garbage crushing method and integrated system thereof adopted of Chinese patent CN1322591 is Hubei Province formula, hammer, impact type, shearing or roll-type, and its fragmentation is to liking hard thing admittedly.In existing technology, remain refuse breaking inadequately evenly, after burning not exclusively, work is undesired, stop up easily and the lower technical problem of efficient.

Summary of the invention:

The purpose of this utility model is: improved at the technical disadvantages that above-mentioned refuse breaking equipment exists, a kind of novel rotation refuse grinder is provided, solve the broken technical problem that exists in the rubbish preliminary treatment.

The technical solution of the utility model is such: rubbish is entered by the hopper of rotation refuse grinder top, falls on the wallboard, blade is installed, as required the size of broken granularity control gap between two in the middle of the wallboard.Rotating shaft is connecting drive system, drives blade rotation, rubbish is pulled the composite breaking mode fragmentation of drawing, pushing and cutting by blade.Blade adopts the symmetry principle of Eight Diagrams to make, and inspiration derives from shredder, and the little rear end of blade front end is big, and the point of a knife place can cut.With general crushing cutter relatively, improve all having significantly aspect stressed and the crushing efficiency.Disintegrating machine adopts Motor Drive, and disintegrating machine inside is provided with guiding gutter and dust cover.

The utility model is achieved in that the rotation refuse grinder is provided with one or several crushing chambers, each pulverizing chamber is installed blade, drive by Power Drive Unit, the complex method crushing chamber that form cutting, pushes and pull, the crushing chamber bottom is provided with guiding gutter, and the top is provided with dust cover.The pulverizing chamber bottom is provided with guiding gutter, and the top is provided with dust cover; The little rear end of blade front end is big, and the insertion slot type design is convenient for changing; The blade employing is corrosion-resistant, wear-resisting, heavy alloy is made, by power drive, and the combined type fragmentation of form cutting, pushing and pullling; Adjust the fineness of refuse breaking 1～200mm by the transposing dividing plate; Guiding gutter and dust cover can be collected percolate and dust automatically.Rubbish enters gas-tight silo automatically through after the fragmentation, and drops on conveyer belt, is transported to next operation.The design of the fixing employing of blade and dividing plate insertion slot type, whole mechanical convenient disassembly is convenient to the replacing and the cleaning of parts.

Above-mentioned blade adopts the insertion slot type design, and sunk key is provided with one or several, and the little rear end of blade front end is big, adopts heavy alloy to make, and is inserted and secured in the rotating shaft.

Above-mentioned crushing chamber is made of several dividing plates, and dividing plate is inserted and secured in the dividing plate holder.

Advantage of the present utility model and good effect:

1, prior art adopts single squash type, hammer, scissors, roll-type, Hubei Province formula fragmentation, and the effect of waste incineration is undesirable.Common waste incineration generally just enters incinerator without fragmentation, is unfavorable for the burning fully of rubbish.And refuse grinder of the present utility model can be with the size of refuse breaking to 1～200mm, satisfies the requirement that rubbish enters in the stove rapidly, burns fully.

2, stop up easily at other refuse grinder, the present situation that efficient is lower, the utility model has good crushing effect to soft rubbish, and treating capacity is big, is difficult for stopping up.Be provided with guiding gutter and dust cover simultaneously, can effectively collect percolate and dust, prevented the pollution of percolate that house refuse produces and dust effectively in fragmentation surrounding environment.

3, the blade of the utility model rotation refuse grinder adopts particular design, guarantees that blade is stressed even in shattering process.

4, the fixedly employing insertion slot type design of the blade of the utility model rotation refuse grinder and dividing plate, whole mechanical handling is convenient, is convenient to the replacing and the cleaning of parts.
