Description

Three roller helical teeth flat-dies roll the cold forming comminutor

Technical field

The utility model belongs to agricultural crop straw particle cold forming process equipment, particularly relates to a kind of three roller helical teeth flat-dies and rolls stalk particle cold forming comminutor.

Background technology

Bioenergy is a kind of important renewable energy, and the agricultural crop straw particle is than the easier realization intensification of other bioenergy large-scale production.External application is quite general, and the Chinese government also attaches great importance to the development and use of bioenergy, has built up many stalk power stations with considerable scale now.Yet stalk power plant all adopts stalk directly to pulverize combustion system at present, and the transportation of stalk, stacking and storage all exist very big problem, and the wide densified straw of traffic coverage is little, and cost of transportation is improved greatly; The stacking space is big, and land occupation is many; Easily produce in the storage process and go mouldy and spontaneous combustion, therefore make the straw power generation cost greatly improve.

Summary of the invention

For overcome cost of transportation height that agricultural crop straw exists, to stack the space big and easily produce and go mouldy and problem such as spontaneous combustion; the utility model provides a kind of three roller helical teeth flat-dies to roll the cold forming comminutor; this utility model can be made agricultural crop straw density greater than 1.2 particle; be convenient to transportation, store and prevent and go mouldy and accident such as spontaneous combustion, thereby the cost of straw power generation is greatly improved.

The technical solution of the utility model is: the outlet of feed hopper connects granulation chamber, and three roller helical teeth granulation mechanisms are installed in the granulation chamber, and granulation chamber connects forming room; Reductor is installed in forming room, and the output shaft of reductor is connected with motor by shaft coupling, and reductor and motor mounting are on base.Three helical teeth milling rollers are installed on the three hole calendering roller shaft couplings that connect firmly with main shaft, and three helical teeth milling rollers contact with rolling to coil, and the helical angle of helical teeth milling roller is 60 °.The sidewall of forming room has discharging opening, rolls dish and is fixed on the sidewall of granulation chamber, and output shaft passes from the bearing that rolls disk center, rolls between dish and the main shaft bearing is housed.The scale scraper plate is equipped with in the lower end of rolling dish, rolls dish and is processed with the moulding hole, and it is straight hole that the interior outer end in moulding hole all is tapered middle part.

Motor output shaft is connected with the power shaft of reductor by shaft coupling, cone pinion on the reductor power shaft is meshed with large bevel gear on the main shaft, the three hole milling roller shaft couplings that three uniform helical teeth milling rollers are housed are installed on the main shaft, three hole milling roller shaft couplings drive the helical teeth milling rollers and clockwise rotate rolling on the dish, and the helical teeth milling roller also rolls under the frictional force effect clockwise simultaneously.

The beneficial effects of the utility model are: simple in structure, and reliable operation, equipment investment is few, is convenient to maintenance, directly cold moudling.Raw material sources are wide, and are easy to use, and also available agricultural miniature tractor band is power drive, are convenient to use in the field, rural area.Product particle density is big, the ratio of briquetting height, and technology is simple, and cost is low.Little good storage of product floor space, can directly act as a fuel provides the stalk plant generator, can also do livestocks such as feed breeding sheep and milk cow.
