Abstract

The utility model relates to a rolling machine fixed roll side buffer protecting apparatus. The apparatus is arranged between a fixed roll and a rolling machine frame, and comprises a buffer block, and the buffer block is fastened between the fixed roll and the frame through a fastener. In the utility model, the above buffer device is arranged between the fixed roll and the frame, so a buffer band is established between the fixed roll and the frame, thereby the damages of relevant apparatuses during the large pressure bearing of a movable roll and a material are avoided, and the safety, reliability and service life of the rolling machine are improved.

Description

A kind of roll squeezer stationary roll side buffer protection device

Technical field

The utility model relates to the mineral pulverizing and uses roll squeezer, is a kind of buffer protection device of roll squeezer fixed roll.

Background technology

Roll squeezer is a kind of milling equipment of the field extensive uses such as modern cement, coal, metallurgy, chemical industry and mine, have simple in structure, lightweight, energy consumption is low, output is high, and advantages such as dust is few, noise is low, good work environment.

Roll squeezer is a kind of high-tension apparatus, fixedly pressure roller and a movable platen are arranged, two pressure rollers rotate in opposite directions, hydraulic system is pressed to fixedly pressure roller to movable platen by 4 cover hydraulic jacks, the extruding force F that forms between two rollers will be squeezed into by material therebetween more closely knit flat material cake, the mechanical strength of this material cake is very low, and hand is twisted with the fingers namely broken.Contain a large amount of fine powders in the material cake, wherein the finished product fine particle less than 90mm accounts for 20～30%, and coarse grained internal structure is destroyed, produces many micro-cracks, and grindability is very high.That is to say that the material particles less than 2 mm in the material cake that pushed accounts for 60～70%, and many micro-cracks are arranged again.This is because be subject in the pressure area causing up to the roller pressure effect of 120MPa by the material between two rollers.In running, hydraulic means can continue provides a huge pressure, roll squeezer also larger vibration can occur when material is unstable, if the words that buffer capacity is relatively poor, the long-term operation meeting is to frame and roller bearing injury, thereby cause the damage of equipment, even can cause security incident.

Present roll squeezer both domestic and external, the hydraulic system of movable roll side arrange nitrogen accumulator buffer unit, but fixed roll and frame are rigid connections, do not design buffer unit, and be unfavorable to the protection of bearing and roll shaft.

The utility model content

The utility model purpose is the problem that proposes in the technical solution background, and a kind of buffer protection device of roll squeezer fixed roll side of simple in structure, superior performance is provided.

The technical solution adopted in the utility model is for this reason: the utility model is arranged between stationary roll and the roll squeezer frame, includes buffer stopper, and buffer stopper is fastened between stationary roll and the frame by securing member.

Described buffer protection device comprises: contiguous block, buffer stopper, briquetting, pressing plate, set gradually briquetting, buffer stopper and connecting plate along stationary roll to the frame direction, and the three is fastenedly connected by pressing plate, securing member.

Described briquetting, buffer stopper are fastened in the connecting plate, are fastenedly connected by pressing plate, securing member.

The utility model has the advantages that: the utility model adds buffer unit between stationary roll and frame, between has been set up a buffer strip, avoid relevant device when being subject to action roller and material immense pressure, to be damaged, improved security, reliability and the service life of roll squeezer equipment.
