Description

Roll squeezer

Technical field

The present invention relates to a roll squeezer, particularly high pressure roll press, it has two roller and the pay-offs that are arranged in anti-phase rotation in the frame, and wherein, fixed panel is axial arranged along roll gap.

Roll squeezer is used for briquetting, pulverizing and compaction treatment.The material that needs to handle send between two rollers by pay-off.Roller forces together these materials or these materials is pulverized or compacting.Handle through these, changed the reset condition of material, as forming briquetting or dust.

Background technology

Before using roll squeezer, need preestablish one with reference to roll gap, roll gap is set by hydraulic pressure in actual the use.In recent years, about sending into the material of roll squeezer, proved that the extruding spacing with two fixed panel restriction extruded products on axially is practicable.

Traditionally, these fixed panels are forever to be connected with frame, like this roll gap along with roll squeezer in use roller surfaces wearing and tearing and enlarge adjustment roller in the horizontal direction.In known press, the conveying of material is permanently connected to by one that feeding funnel on the frame realizes.The sidewall of feeding funnel can be regarded as and moves tongue piece and supply with materials flow.

In known design, the adjustment of roller uses bigger and less dividing plate to carry out discontinuously.Bigger baffle arrangement is between bearing bore that moves horizontally on the frame and vertical frames parts, and move in the space of less dividing plate between two bearing bores.In order to prevent that roller from no longer mating the appearance of this problem with the conveying of material after operation a period of time, the corresponding dividing plate that must take off the roller both sides keeps in repair.

In use, roll squeezer stands bigger wearing and tearing, therefore, must keep in repair or replace in the regular period.In practice, high pressure roll press generally drives by planetary gear, wherein the planetary gear suspension strut on the roll shaft pin and support interact and to interact by moment of torsion conversion bearing in other words.Because the wearing and tearing in the use if must replace roller, at first will be removed planetary gear before tearing roller open.Period for removal will cause the shut-down of roll squeezer when maintenance and inspection.

Generally speaking, there are many defectives in existing roll squeezer, particularly pushes some corrosion products, and this can cause the higher wear rate of roller.In this case, be necessary to use economic means to reduce the wearing and tearing of roller, prolong the life-span of roller.Because wearing and tearing, the horizontal adjustment of pair of rollers or fixed panel are constantly in use arranged.In the adjustment of roll gap, need to interrupt the use of roller, the turned letter feeding funnel, thus cause corresponding shut-down.Adjustment work is time-consuming very, also needs other auxiliary equipment sometimes, and this has just increased the cost of downtime.Because the roller adjustment, move with respect to pay-off at the center of roll gap.As a result, optimization utilizes mobile tongue piece to carry needs pressing materials destroyed, so often need adjustment pay-off again.

Describe as the front, these only relate to adjustment work, also do not relate to the thing of replacing roller.But if must replace roller, this has just brought problem and extra charge again.Like this, the planetary gear of press must be pulled down, and also needs lifting equipment, and as crane, this can spend higher expense and time.If the frame of roll squeezer can be opened from a side, when replacement was positioned at the rear side roller on opening opposite, two planetary gears at first needed to pull down, and the front side roller will be removed.Except tongue piece, fixed panel and connected fixture and gauge member must be removed, and at this moment the rear side roller just can take out.
