Description

Roller type pills making machine

The utility model belongs to the main frame in the compound fertilizer production technology, particularly a kind of compaction type comminutor.

At present, in the domestic production compound fertilizer technology, what wherein main frame adopted is dribbling balling machine, and the operation principle of this machine is by falling within the deadweight of material in the dish, by the mutual rolling movement of material, and the irregular garden of bonding one-tenth shape spheroid.Because two kinds in the nitrogen potassium in the composite fertilizer in main three elements nitrogen, phosphorus, the potassium is not had viscosity, only depends on the viscosity adhesion of a kind of element of phosphorus, thereby, be difficult to form uniform ingredients, the high-grade compound fertilizer that nitrogenous potassium composition is many.

China spent 220,000 funds to introduce an extruder that is used for production composite fertilizer from Japan in 1984, used in Zigong City chemical plant, Sichuan, and the general structure of this machine is seen Fig. 1.It mainly by main shaft 1 ', motor 2 ', pinch roller 3 ', scraper plate 4 ', eye plate 5 ', sweeping through the material scraper plate 6 ' and housing 7 ' composition, wherein, main shaft 1 ' for being arranged vertically, motor 2 ' be arranged horizontally, between them by one group of belt pulley 8 ' by 110 kilowatts motors 2 ' driving, make the one-level deceleration transmission, by one group of modulus 16, speed this 10, worm gear 9 ' diameter is φ 600, worm screw 10 ' diameter is φ 300, worm screw a 10 ' number is that 3 garden arc worm and gear is paid and done the double reduction transmission, and changes transmission direction, sees Fig. 2.Eye plate 5 ' with housing 6 ' link, be arranged horizontally, eye plate 5 ' on have many holes, the shape in hole is seen Fig. 3.Pinch roller 3 ' be installed in eye plate 5 ' above, with main shaft 1 ' directly link, with the rotating speed identical with main shaft around main shaft 1 ' revolve round the sun, scraper plate 4 ' be installed in pinch roller seat 14 ' on, sweeping through the material scraper plate 6 ' be installed in eye plate 5 ' below, with main shaft 1 ' with axle rotates with speed, see Fig. 4 by scraper circle 12 ' and key 13 ' link.The operation principle of this machine is, after material is come in from the top, falls above the eye plate, extruded many holes from eye plate by pinch roller.Simultaneously, scraper plate scrapes the material of building up on housing 7 ' inwall, and the material that extrudes from eye plate forms the different column pellet of length, falls within the pellet under the eye plate, by the sweeping through the material scraper plate by discharging opening 11 ' release.

This function is produced high-grade composite fertilizer, and the productivity ratio height, but it also has following problems: (1) adopts 110 kilowatt motors, and energy consumption is big.(2) the manufacturing process complexity of worm and gear device, difficulty of processing is big, the production cost height.(3) its eye plate is owing to adopt stainless steel, and its hardness is low, and eyelet is stairstepping, and the cross section is little between adjacent eyelet, influences eyelet zone intensity, and its life-span is reduced, and wearing and tearing are just discarded after half a year, can not be multiplexing, increased production cost.(4) sweeping through the material scraper plate rotating speed is too high, easily granular material is smashed.

The purpose of this utility model is exactly for a kind of shortcoming that promptly overcomes above-mentioned Japanese extruder is provided, and it is little to have volume again, and output height, kernel productivity be more than 98%, compaction type comminutor that can production high-grade composite fertilizer characteristics.

The utility model is with reference to above-mentioned Japanese extruder principle design, it is mainly by the main shaft 1 similar with Japanese extruder, motor 2, pinch roller 3, scraper plate 4, eye plate 5, sweeping through the material scraper plate 6 and housing 7 are formed, wherein, main shaft 1 is for being arranged vertically, motor 2 is arranged horizontally, and connects by deceleration device and reversing arrangement between them, and eye plate 5 is arranged horizontally, link with housing 7, have many holes on it, the shape in each hole is divided into three parts, and the middle part is the garden cylindricality, two parts are taper up and down, the length of garden, top awl is less than 2mm, and in the eye plate upper surface, adjacent two hole Wai Yuan distance the most nearby must not surpass 0.5mm, pinch roller 3 is installed in above the eye plate 5, link by pinch roller seat 15 and wheel pressing shaft 16 with main shaft 1, revolve round the sun around main shaft, pinch roller 3 self also can be done rotation around wheel pressing shaft, scraper plate 4 is installed on the pinch roller seat 15, revolve round the sun together with pinch roller, sweeping through the material scraper plate 6 is installed on the inner gear ring 13 below the eye plate 5, links with main shaft 1.When material after its top feed mouth of the present utility model enters into above the eye plate 5, in the pinch roller 3 that main shaft is done revolution is pressed into material many apertures on the eye plate 5 gradually, simultaneously, scraper plate 4 scrapes the material of building up on pinch roller seat 15 bottoms and housing 7 inwalls, along with pinch roller further rolls, material is extruded into the column pellet of varying length from the aperture of eye plate 5, fall on the base plate 18, pellet is slowly released through discharging opening 12 by sweeping through the material scraper plate 6 again.

Deceleration device and reversing arrangement between the utility model motor 2 and the main shaft 1, be to utilize one group of garden arc helical teeth crop rotation one-level deceleration transmission, in one group of homemade the Yellow River automobile axle tooth bag, modulus is 6, speed ratio is that 6.6 arc hypo gear is done the double reduction transmission, and changes transmission direction.

Sweeping through the material scraper plate 6 of the present utility model is to be driven by the fewer differential teeth planetary deceleration device by main shaft 1, with the rotating speed that is lower than main shaft 1 around main axis rotation.

Eye plate 5 of the present utility model is to adopt the alloy cast steel material of 1Cr18Ni13Mn9Cu3Ti to make; This material corrosion resistant, wear-resisting, back hardness height quenches.

The utility model is compared with Japanese extruder, not only concrete output height (2.5 tons/hour～4 tons/hour), volume is little, can produce high-grade composite fertilizer, it is low also to have energy consumption, easy to manufacture, the eye plate life-span is long, and totle drilling cost is low, sweeping through the material scraper plate rotating speed is slow, be difficult for pellet is smashed, make kernel productivity remain on 98%, be suitable for China production composite fertilizer and use with first-class advantage.
