Description
Technical field
The utility model relates to a kind of pressure twin rollers that is used for industries such as building material cement, metallurgical mine, coal, chemical industry.
Background technology
The pressure twin rollers is widely used in fields such as the material fragmentation, grinding, balling-up, granulation of industries such as building material cement, metallurgical mine, coal, chemical industry, in use because the existence of edge effect makes the edge of two pair roller rollers not carry out fragmentation, grinding, balling-up, granulation to material well.With the roll squeezer is example, and roll squeezer belongs to operations involving high pressure to the extruding of material, very easily extrudes at the two ends of two compression rollers or the material at both sides roll gap place.Being extruded this part material can not be squeezed well, so bulky grain is more.Practice shows, in the material of roll squeezer extruding, all is because so-called roller end leaks material causes greater than the particle overwhelming majority of 2mm.This not only makes the mill efficiency of roll squeezer be had a strong impact on, and is especially just even more serious to the influence of narrow roller roll squeezer, and also brings very big difficulty for the normal running of roll squeezer.What have returns this part material to roll squeezer and pushes again, though this can solve the too much problem of bulky grain, has a strong impact on mill efficiency.With the ball press is example, and the material at roller edge can not the compacting balling-up.Because edge effect arranged, some materials not only can not make material that effective function is arranged during by the roller edge, can cause roller edge abrasion aggravation on the contrary, have a strong impact on the roller life-span, and the Increasing Production and Energy Saving effect of pair roller machinery is had a greatly reduced quality.
Past because the influence that edge effect produces is adopted the way that adds side shield at the roller end position, has been obtained effect preferably in order to reduce.In order to guarantee the suitable precompression of side shield, adjusting place is provided with the buffering link, so as to reducing the shock and vibration that produce because of material is inhomogeneous.Since side shield be fix and roller rotates, can not reduce the wearing and tearing of roller end face effectively.
The utility model content
The purpose of this utility model is at above-mentioned situation, and the pressure twin rollers of a kind of effective minimizing edge effect, enhancing material charging ability is provided.
The purpose of this utility model realizes by following technical proposals:
A kind of pressure twin rollers comprises in opposite directions the action roller and the fixed roll of rotation, respectively is provided with 2 blocking material rings in the both ends of the surface of described action roller or fixed roll;
When blocking material ring was arranged on the action roller, the radius of described blocking material ring left the positive-effect gap greater than the action roller radius between feed pipe and action roller, left between feed pipe and the fixed roll to prevent from the gap that rubs to be provided with on action roller blocking material ring is carried out spacing stopping means;
When blocking material ring is arranged on the fixed roll, the radius of described blocking material ring is greater than the fixed roll radius, leave the positive-effect gap between feed pipe and fixed roll, leave between side shield on the feed arrangement and the blocking material ring and prevent from the gap that rubs on fixed roll, to be provided with blocking material ring is carried out spacing stopping means;
Described positive-effect gap is meant the rotation that utilizes blocking material ring, drives material and do the gap that positive work stays.
As optimal way, described positive-effect gap is 0.5-3 a times of roll gap.
As optimal way, when blocking material ring is arranged on the action roller, the radius of described blocking material ring=action roller radius+action roller stroke+5mm.
As optimal way, when blocking material ring is arranged on the fixed roll, the radius of described blocking material ring=fixed roll radius+action roller stroke+5mm.
As optimal way, when blocking material ring was arranged on the action roller, the gap that preventing between described feed pipe and the fixed roll rubbed was 0.5-5mm.
As optimal way, when blocking material ring was arranged on the fixed roll, the gap that preventing between described side shield and the blocking material ring rubbed was 0.5-5mm.
As optimal way, when blocking material ring is arranged on the action roller, leaves between described blocking material ring and the fixed roll and prevent blocking material ring and the fixed roll end face gap of mutual friction mutually.
As optimal way, when blocking material ring is arranged on the fixed roll, leaves between described blocking material ring and the action roller and prevent blocking material ring and the action roller end face gap of mutual friction mutually.
As optimal way, described blocking material ring is carried out spacing stopping means is the limited step that is arranged on action roller or fixed roll two ends or the roll surface.
As optimal way, described blocking material ring is the split-type blocking material ring.
The beneficial effects of the utility model:, material is flowed away as few as possible from the roller edge at the blocking material ring of action roller or fixed roll both ends of the surface; Limited step is in order to supporting blocking material ring, and can prevent that blocking material ring from being strutted by material; The gap that preventing between blocking material ring and fixed roll or action roller rubbed produces when being used for preventing moving owing to action roller and tilts to make blocking material ring to produce with fixed roll or action roller end face to rub; Blocking material ring is arranged to split-type so that dismounting and replacing; The radius of blocking material ring is that action roller or fixed roll radius add the action roller stroke and add 5mm again, and the benefit of She Zhiing is both to have guaranteed that blocking material ring can seal material like this, can make blocking material ring do minimumly again; Positive-effect gap between feed pipe and fixed roll or the action roller utilizes the rotation of blocking material ring to drive material and does positive work, prevents that material from flowing away along fixed roll or action roller; The combination of said structure significantly reduces edge effect, makes material also obtain effective extruding at the roller edge, rim charge can not occur and run thick phenomenon, and the granularity of rim charge is the same with middle material or thinner, and rim charge also can effectively be pushed; The end wear of roller is avoided simultaneously; Blocking material ring the charging ability that has strengthened material is set, produce the material of plugging for charging, solved its putty problem; In order to make blocking material ring that maximum band material effect be arranged, make the edge positive band material effect occur, can make the positive-effect gap between feed pipe and action roller or fixed roll big as far as possible.
