Description

A kind of novel ring mode granulator

Technical field

The utility model relates to a kind of novel ring mode granulator, specifically uses the ring mode granulator that powder-materials such as poultry-dung after municipal refuse, ight soil mud, sewage sludge, the fermentation process, papermaking mud, feed, lime are granulated.

Background technology

At present, the existing ring mold pressing roll-type granulator that can granulate to the powder-materials such as mixture that add binding agent in pulverizing fines, feed, lime and the rice skin carbide of the poultry-dung after municipal refuse, ight soil mud, sewage sludge, the fermentation process, papermaking mud, fish guts, fishbone, pineapple peel, bark, sawdust, culled wood.Its structural design is to adopt raw material through pressure roller and ring mould, and raw material is squeezed to the outside from ring mould inwall and forms graininess.The raw material that pressure roller and pressing mold were asked when the granulator of this kind structure was worked forms solid easily, piles up easily, easily causes and cause the machine stall by the moulding hole plug, damages; Product is when granulating, and owing to high temperature, high pressure, composition easily changes, and is difficult for melting, and effectively bacterium easily is killed; Owing to the higher pressure of employing, with respect to the power of granulator, output is low, and fast (rotating speed the is 200-400 rev/min) noise of rotation is big, granulation cost height; Because high temperature production needs large-scale cooling device after the granulation; Granulation for the many compost of inorganic matters such as the compost that the rice skin is arranged, lime, fermentation sewage sludge etc. is just relatively more difficult; Need add grease things such as rice bran when start, when shutting down, otherwise can cause the moulding hole plug, part is changed, is adjusted and safeguard relatively difficulty in addition.

Summary of the invention

In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of simple in structure, compact, reasonable; Can prevent that temperature from rising; granulate at low temperatures; can guarantee that raw material is squeezed into graininess; suppress the rising of pressure, the production efficiency height, grain shape can be made into multiple difformity; the ring mould rotates slowly, noise is little; foreign matter in the raw material can be discharged by the gap of ring between the mould, and the ring mode granulator of fragile machine not.

For achieving the above object, technical solutions of the utility model are:

A kind of novel ring mode granulator, described granulator comprise reductor, shaft coupling, transmission mechanism gear-box, support, be installed in motor on the support, revolve the sieve that shakes, be installed in and revolve the vibrating motor on the sieve that shakes and be contained in feed hopper on the body; Described reductor is connected with motor, speed reducer output shaft is connected with shaft coupling one end, the other end of shaft coupling is connected with the power shaft of transmission mechanism gear-box, that described transmission mechanism gear case body is provided with is main, by two moving axis, and be connected with a pair of active and passive gear of transmission mechanism gear case body respectively, be equipped with a ring mould on described driving shaft and the driven axle, form pressure angle between the two ring moulds.

Described two ring moulds are provided with the moulding hole.

The section of pass in moulding hole is circle or semilune or pentalpha or triangle or ellipse or dumbbell shape on the described two ring moulds.

Also be provided with an eccentric wheel on the described driven axle.

The usefulness of technique scheme is:

1) this new structure, temperature rises in the time of effectively preventing work, makes when requiring that (below 50 ℃) granulate under low temperature environment, need not to set up large-scale cooling device, has saved production cost greatly; Can guarantee that raw material is squeezed into graininess, suppress the rising of body internal pressure.

2) this novelly is provided with two ring moulds, discharging simultaneously, and the efficient height has improved 1.8-2 doubly than original greatly, and the ring mould speed slow (40-120 rev/min) of rotating, and noise is little, below 75 decibels.

3) two rings form pressure angle between the moulds, make the moulding hole of ring mould be difficult for stopping up, and are not fragile during the machine stall, and machine changes, easy to maintenance, and simultaneously, the foreign matter in the raw material also can be discharged not fragile machine by the gap between the ring mould.

4) this novel granulator, applied range, for many compost of inorganic matter such as the compost of rice skin, lime, the assorted raw materials such as municipal refuse of the mud of fermentation sewer, composition all can conveniently be granulated.

Below in conjunction with the drawings and specific embodiments the utility model is further described.
