Description

Particle machine

Technical Field

The utility model relates to a particle machine technical field, specifically say, relate to one kind and can be effectively handle the agriculture and forestry waste material that humidity is great, fibre content is higher for the particle machine of tiny granule.

Background

The environmental protection problem is one of the important problems for constructing ecological civilization. On one hand, the method controls through relevant policies, on the other hand, the method carries out industrial major tuning, promotes scientific and technological innovation, and solves a plurality of problems in environmental protection by utilizing new technology application. Among them, the prohibition of burning agricultural and forestry wastes is an important aspect of reducing environmental air pollution, and although relevant policies are implemented for many years, relevant departments also spend great manpower and financial resources, the effect is difficult to be ideal, and the situation is likely to continue.

Agricultural waste includes crop stalks, straw, etc., and forestry waste includes old fruit trees, twigs, barks, leftover bits, etc., and eradicated weeds, shrubs, etc. Most of the plants are directly cut or collected, the plant fiber content is high, the humidity is high under the condition that the plants are not dried after cut or collection, the plants are generally treated as waste garbage, the subsequent treatment cost is very high, and the plants are large in quantity, wide in dispersion area, low in value, difficult to treat and narrow in available range. The existing treatment mode is that the agriculture and forestry waste materials distributed in a large range are collected and then simply cut into small pieces for treatment, but the waste materials are still waste materials, have no market economic value and no treatment enthusiasm, and the corresponding environmental protection policy can only be forcibly promoted by strengthening supervision and issuing subsidies by relevant departments, so that a large amount of manpower and financial resources are consumed, the effect is still unsatisfactory, and the environmental protection problem is difficult to solve fundamentally.

After investigation, the inventor finds that, for the directly felled/collected agricultural and forestry waste materials such as branches, crops, shrubs and the like which are not dried, have large humidity and high fiber content, because the waste materials belong to plant materials, if the waste materials can be treated to a small degree in certain specific fields, the waste materials can play a role, generate a utilization value, exert a market economic value, reversely promote the enthusiasm of people for treating the materials, and promote the execution of an environmental protection policy by utilizing the market economic characteristic. Such as organic fertilizer production, mushroom planting, machine-made charcoal production, breeding industry, straw returning and the like. However, in the production of fertilizers, if the granularity of materials is not small enough, the time of fermentation treatment procedures can be obviously increased, the production effect and the production process can be influenced, and organic fertilizer manufacturers can naturally not consider recovering the plant wastes; in mushroom planting, if the material can not reach the level of the conventional sawdust material, the material is difficult to apply; in the production of mechanical carbon, the plant raw materials have specific requirements, and the granularity must be less than 3-5 mm; in the breeding industry, plant materials which are fine enough can be used as feed fillers; in the field returning of the straws, if the granularity of the plant materials such as the straws returned to the field is not small enough, the process of forming humus in the field is greatly increased, the original effect of the soil can be influenced before the humus is formed, the soil fertility cannot be increased, the subsequent agricultural production activity can be seriously influenced, and the like.

Taking the organic fertilizer industry as an example: at present, the aspects of building plants, purchasing equipment, collecting and treating raw materials and the like are subsidized, but the viability of organic fertilizer plants is still a problem, and the main reason is that the existing production cost is high. Organic fertilizers have a wide market, but need to compete with other fertilizers for the market, and the cost performance is critical. Only by reducing the cost can the wide market be occupied. But the cost is difficult to reduce due to the existing treatment process. The current treatment process comprises the following steps: collecting, storing, drying, crushing, mixing additives and fermenting. The difficulty lies in the links of collection, storage, drying and pulverization. And (3) a collection link: because the plant substances are loose and widely distributed, the collection needs to cost a lot of labor cost and transportation cost. A storage-drying link: because the materials are loose, a large area of field is needed for storage, and the drying time is long (generally, a natural air drying mode is adopted, and if a drying device is adopted, high equipment purchasing cost and high energy consumption are needed), so that high storage cost is generated and the risk of fire is high. And (3) a crushing link: because the prior art can only crush and process dry materials, the power demand is high, the energy consumption is high, the noise in a production workshop and dust are very large, serious problems exist in safe and environment-friendly production, the fire risk and the explosion risk exist, the occupational disease risk of staff also exists, and the environmental air pollution is serious. Therefore, the direct cost, the indirect cost and the potential cost of the organic fertilizer production are high, even if subsidies are added, the competitive advantages are still not achieved, and the organic fertilizer industry is still difficult to develop and develop. In addition, theoretically, the wide organic fertilizer market can enable the production of organic fertilizers to become the main power for eliminating agricultural and forestry wastes, and the development of the organic fertilizers cannot be realized, so that the environmental protection policy of prohibiting incineration is difficult to implement.

The existing industrial equipment for processing materials into small volume mainly comprises a crusher and a chipper. The crusher mainly uses a hammer structure which continuously rotates to hammer materials, and then discharges the materials through a screen, but only dry materials can be processed, and the crusher has poor effect on the materials which are not dried, have high humidity and high fiber content and basically cannot achieve the required crushing granularity; when materials with high humidity are actually treated, a drying process is added before treatment, the natural drying time is long, the equipment drying energy consumption is high, and the integral treatment cost is very high. The chipper generally aims at plant raw materials such as bamboo and wood, and the continuously fed materials are cut into small pieces and discharged through a rotating fly cutter structure, but the particle size of the sheet materials obtained by conventional structure treatment is limited (the thickness is generally 3-5mm, and the length is 15-20mm), the required particle size cannot be met, and the sheet materials with high humidity and high fiber content are difficult to treat. The failure to effectively treat plant waste materials with heavy water and heavy fiber is also a pain point and difficulty in the industry.

Therefore, it is necessary to develop a device for crushing and processing the directly felled/collected branches/crops/shrubs which are not dried, have high humidity and high fiber content and other forestry and agricultural residues which are conventionally treated as garbage into particles with practical utilization value, and the particles can meet the requirements of further production and processing in some specific fields by using the particles as raw materials.

The fine particles referred to in the art are regular or irregular fine particles each having a maximum dimension of 5mm or less.
