Description
Technical field
The present invention relates to garbage disposal machinery, be specifically related to a kind of blanking block that is installed in the garbage pulverator.
Background technology
The rubbish that produces in human being's production and the life, it promptly is a kind of pollution sources, and it is a kind of available energy.China is second largest energy-consuming state in the world today, and according to development of Chinese economy speed over the past two decades, before 2015, China estimates the demand of the energy will be with annual 4%～5% speed increment.With this speed, by 2025, China will become maximum in the world energy-consuming and greenhouse gas emission country.There is exhausted crisis in the conventional energy resource (coal, oil, natural gas) of China, and resultant problem of environmental pollution also is badly in need of controlled.It is predicted that China's domestic waste in 2010 has reached 2.2 hundred million tons, if calculate with Lower heat value 800Kcal/kg, amount to calorific value and be 2,154 ten thousand tons of the standard coals of 7000Kcal/kg,, generating equipment 466MW can be installed as all calculating in order to generating and by 20% generating efficiency.At present China's domestic waste every year is just with 10% speed increase, and the municipal refuse of implementing simple and easy processing only accounts for 2.3% of total amount, because China can use the soil to be less than 3.85% of the U.S. per capita, China's rubbish heap storage over the years is up to 6,000,000,000 tons at present, occupy cultivated land 500,000,000 square metres, direct economic loss reaches 8,000,000,000 yuans.National urban has now developed into 660, and wherein existing 200 cities are absorbed among the rubbish encirclement.With urban population 2.6 hundred million, produce 440 kilograms of rubbish for each person every year and calculate, producing quantity of refuse is 1.14 hundred million tons, can make the city of 1,000,000 populations cover 1 meter.And also increasing progressively with 8～10% every year.China has become the heaviest country of rubbish burden in the world, municipal refuse innoxious, subtract appearanceization and recycling treatment is extremely urgent.But then, if with its whole utilizations, then be equivalent to the energy of 1,340 ten thousand tons of oil.
The energy process of quickening garbage disposal is the focus that countries in the world are paid close attention to, garbage derivatived fuel manufacturing technology (RDF technology) is ripe relatively abroad, in developed countries such as Japan, Germany, the U.S. the special company that is engaged in the operation of RDF fuel production is arranged, effectiveness of operation is good.What but they handled all is the stable sorting rubbish of component.For Chinese refuse moisture big (moisture reaching about 30%. in the rubbish), refuse thermal value is low, complicated component (contains in the rubbish: porcelain, brick, rubble, hard foreign material such as glass) characteristics, in the technology that the burning electricity generation of existing China rubbish is handled, at first be that rubbish is pulverized, increase the fuel that combustion adjuvant is made into certain specification and shape, because the characteristics of China's rubbish, the pulverizing problem of the composting of complicated component, be technical barrier anxious to be solved in the technology handled of the burning electricity generation of China's rubbish, the rubbish that the various pulverizing that prior art is used all can't be satisfied in the waste incineration and generating electricity treatment process is pulverized problem.Biological straws etc. are very easy to blocked in pulverizer, and the material after the pulverizing can't be excreted out smoothly, therefore are necessary prior biological straw kind garbage pulverator is carried out necessary improvement.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, structure to the blanking block in the existing stalk class volley pulverizer is improved, make pulverizer behind the blanking block of having installed after improving, can be swimmingly with unfinished the excreting out after pulverizing, and this blanking block is simple in structure, processing and fabricating is easy, and Installation and Debugging are easy.
For achieving the above object, technical scheme of the present invention is the blanking block that adopts in a kind of pulverizer, blanking block is the strip metal derby, be installed in the both sides of pulverizing cutting tool in the pulverizer, described strip metal derby comprises the cuboid part and is positioned at the A prismatoid part at the triangle body part of cuboid one upper lateral part, middle part and the B prismatoid part of bottom that the one side in described triangle body, A prismatoid and the B prismatoid coincides with the one side of described cuboid.
Wherein, described triangle body is the square triangle body, described A prismatoid and B prismatoid are the prismatoid that five mutual vertical planes and inclined-plane constitute, and the one side in the described triangle body coincides with one side in the A prismatoid, and the one side in described A prismatoid and the B prismatoid coincides.
Wherein, the inclined-plane of described A prismatoid is an arc surface; Described arc surface is used for matching with described pulverizing cutting tool, and described pulverizing cutting tool is installed on the circular drum.
Wherein, in described B prismatoid and described A the prismatoid one side and the angle between the described inclined-plane that coincide be 40 °～80 °.
Wherein, in described B prismatoid and described A the prismatoid one side and the angle between the described inclined-plane that coincide be 60 °.
Wherein, in described A prismatoid and the angle between the profound line of the one side that coincides of described B prismatoid and described arc surface be 40 °～80 °.
Wherein, in described A prismatoid and the angle between the profound line of the one side that coincides of described B prismatoid and described arc surface be 60 °.
Wherein, smooth excessiveness is connected between the inclined-plane in the arc surface of described A prismatoid and the described triangle body.
Wherein, described metal derby is a hard alloy steel.
Wherein, the thickness of described metal derby is 3cm～6cm.
Advantage of the present invention and beneficial effect are, the blanking block after improving in the pulverizer can make the material after pulverizer is pulverized excrete out from the discharge gate of pulverizer swimmingly, can not appear at the boring accumulation phenomenon of blocking in top of pulverizer.And this blanking block is simple in structure, and processing and fabricating is easy, and Installation and Debugging are easy, produce with use with low cost.
