The utility model has simple structure and low manufacturing cost, can rapidly extrude the material forming layer, reduces the escape phenomenon of the material during extrusion, improves the processing rate of the material, improves the production capacity and eliminates the material mixing phenomenon; the tungsten carbide studs are embedded on the flange surface in the working area, so that the wear can be prevented, the service life can be prolonged, the service life of the tungsten carbide studs and the service life of the roll surface can be prolonged, and the service life of the whole tungsten carbide stud and the service life of the roll surface can be prolonged.

Description

Material leakage prevention structure for roller press

Technical Field

The utility model relates to a roll squeezer field specifically is a leak protection material structure for roll squeezer.

Background

The high-pressure roller mill is crushing equipment widely used in the cement industry, and the working principle of the high-pressure roller mill is that materials are crushed through the rotation of two high-pressure rollers; the high-pressure roller mill has the advantages of small occupied area, energy conservation, fine crushing granularity, large processing capacity and the like, and is increasingly and widely applied to industries such as mines, chemical engineering, building materials and the like in recent years; when the high-pressure roller mill works, materials falling from the feeding port are extruded by the two high-pressure rollers and are crushed, the materials are likely to scatter around after being crushed, and the materials falling on the edges of the front end and the rear end of the two high-pressure rollers are likely to pop out from the front end and the rear end of the high-pressure rollers and fall into the high-pressure roller mill, so that the work of the whole machine is influenced, and the treatment rate of the materials is reduced; the inner space of the common high-pressure roller mill is compact, almost no space with a new structure is added, if a material leakage preventing device with a complex structure is designed, the material leakage preventing device cannot be installed in the high-pressure roller mill, and the manufacturing cost of the product designed by enterprises generally needs to be considered, so that the device which is simple in structure, low in manufacturing cost and capable of preventing material leakage needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and providing a leak protection material structure for roll squeezer, simple structure, low in manufacturing cost.

The utility model provides a problem, the technical scheme who adopts is:

the utility model provides a leak protection material structure for roll squeezer, includes the fixed roll and moves the roll, and the both ends face of one of them roll surface of fixed roll or moving roll has the flange through bolted connection respectively, and the diameter of flange is greater than the diameter of roll surface to wrap up the high pressure zone material between two roll surfaces, the flange rotates along with roll surface and high pressure zone material synchronization, inlays respectively on the inboard of flange and has the tungsten carbide stud.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:

the utility model has simple structure and low manufacturing cost, the flange is a simple mechanical part, the manufacturing method is mature, and the assembly can be completed only by fixing the bolts; the material forming layer can be extruded quickly, so that the escape phenomenon of the material during extrusion is reduced, the processing rate of the material is improved, the production capacity is improved, and the material mixing phenomenon is eliminated; the pressure of the material can be uniformly dispersed, segregation caused by uneven pressure or abrasion of the middle part of the roller is eliminated, the point load cut on the stud is reduced, and the stud fracture phenomenon is avoided; the tungsten carbide studs are embedded on the flange surface in the working area, so that the wear can be prevented, the service life can be prolonged, the service life of the tungsten carbide studs and the service life of the roll surface can be prolonged, and the service life of the whole tungsten carbide stud and the service life of the roll surface can be prolonged.
