Description

Ring die pelleter

Technical field

The utility model relates to the granulator field, a kind of ring die pelleter in bioenergy such as especially a kind of wooden, tangerine bar and feed, the spam application field.

Background technology

At present; The feed granules make-up machine that comparative maturity is arranged on the domestic market; Also ripe without comparison wood substance grain make-up machine, because the hardness of the hardness ratio feed granules raw material of wood substance grain raw material is much bigger, pressure is big during processing wood substance grain pelletizing forming, temperature is high.But the critical piece pressure roller assembly back shaft of existing feed granules make-up machine is all cantilevered axle in the hollow shaft of ring mould homonymy, pressure roller assembly back shaft fracture probability is big, maintenance difficult.Roller bearing is in compression chamber, and its bearing is at high-temperature, high pressure, and high dust atmosphere operation down is easy to break down, and processes wooden particle per ton and needs nearly 80 yuans of loss bearing and butter.The applicant has applied for that on July 9th, 2011 application number is 201120255389.6 utility model patent; This patent is changed into the roller bearing in original compression chamber outside the compression chamber; And this pressure roller can also be regulated through the external eccentric bushing with the gap of ring mould; Equipment failure rate reduces, and prolongs the service life of bearing effectively, but also has certain limitation in practice.

Summary of the invention

The purpose of the utility model is, overcomes the defective of prior art, and a kind of high efficiency is provided, the ring die pelleter that fault rate is low.

For realizing said purpose, the technical scheme that the utility model provides is following: construct a kind of ring die pelleter, comprise support, drive motors, decelerator, be equiped with the ring die holder at the output shaft of decelerator; The ring die holder closely is connected with the ring mould, and the pressure roller assembly is arranged in the ring mould, constitutes compression chamber with the ring mould; The pressure roller of pressure roller assembly is fixed on the pressure roller shaft through roller bearing; The front portion of pressure roller shaft is installed on the roller seat, and the roller seat bottom is installed in the support top, and the roller seat rear end is provided with connecting rod; The pressure roller shaft rear end is connected with connecting plate, and connecting plate is connected the connecting rod rear end; Periphery offers cannelure to pressure roller shaft at the roller bearing place, and cannelure portals and is communicated with axial cooling fluid hand-hole, axial cooling fluid that pressure roller shaft is axially offered.

Axially cooling fluid hand-hole, axial cooling fluid are portalled and are connected with hydraulic jack through hydraulic pump, form pressure roller shaft bearing cooling device.

The forward and backward two end cap of roller bearing is provided with packing, and the screw thread of offering on packing and the pressure roller shaft constitutes sealing dust-proof device.

The pressure roller shaft front end also is provided with the eccentric adjuster of adjustment ring mould and nip.

Ring mould periphery is provided with two or more spring bearings.

The pressure roller assembly is more than two covers or two overlap.

The utility model supports and encircles mould support the same side with original pressure roller assembly and change front and back two sides into through original technology is carried out significant improvement and innovation, has reduced the difficulty of processing of ring mould back shaft, and granulator is simplified the structure, and equipment failure rate reduces; Also increased the Control device of liquid cooling of roller bearing, made the roller bearing temperature be lower than 100 degree, improve service life greatly; Through setting up packing and screw thread the sealing and dustproof performance of bearing is improved, reduce bearing butter use amount.

The specific embodiment

Be further described below in conjunction with accompanying drawing and preferred embodiment concrete technical scheme with regard to the said ring die pelleter of the utility model.

Consult Fig. 1～Fig. 4.A kind of ring die pelleter comprises support 1, drive motors 2, decelerator 3, is equiped with ring die holder 4 at decelerator 3 output shafts; Ring die holder 4 closely is connected with ring mould 5; Pressure roller assembly 6 is arranged in ring mould 5; Constitute compression chamber 7 with ring mould 5, pressure roller assembly 6 comprises symmetrically arranged left pressure roller assembly 60, right pressure roller assembly 61.Left side pressure roller assembly 60 is identical with the structure of right pressure roller assembly 61, and existing is that example describes with left pressure roller assembly 60.The left pressure roller 62 of left side pressure roller assembly 60 is fixed on the left pressure roller shaft 64 through left roller bearing 63; The front portion of left side pressure roller shaft 64 is installed on the roller seat 8; Roller seat 8 bottoms are installed in support 1 top; Roller seat 8 rear ends are provided with connecting rod 81, and left pressure roller shaft 64 rear ends are connected with connecting plate 65, and connecting plate 65 is connected connecting rod 81 rear ends; Left roller bearing 63 place's peripheries of left side pressure roller shaft 64 offer left cannelure 641; Portal and 645 be communicated with in the left side that a left side cannelure 641 and left pressure roller shaft 64 are axially offered axially cooling fluid hand-hole 643, the axial cooling fluid in a left side; A left side axially cooling fluid hand-hole 643, a left side axially cooling fluid portal and 645 be connected with the hydraulic jack (not shown) through the hydraulic pump (not shown), form left pressure roller shaft 64 bearing refrigerating plants.
