Abstract
The utility model discloses a novel roller press. The roller press comprises a first press roller and a second press roller which are parallelly arranged; the diameters of the roller surfaces of the first press roller and the second press roller are different; and the shapes of the roller surfaces of the first press roller and the second press roller can be single-section straight lines, multi-section straight lines or arc surfaces. The diameters of the two press rollers on any one of transverse tangent planes are different when the two press rollers which work in a matching mode revolve at the same angle speed, so that the surfaces of the press rollers have different linear speeds; and therefore, the force which is applied to materials by two press rollers which work in a pairing mode is extrusion force, and tearing force against the materials is added; and the materials are easily crushed under an action of the tearing force so as to avoid formation of material cakes, so that the crushing fineness is improved, and the using of a beater is avoided; and moreover, because the contact surface is increased, the yield of the roller press is correspondingly improved.
Description
Technical field
The utility model relates to a kind of roller press, relates in particular to a kind of roll squeezer that cement industry carries out material crushing that is applied to.
Background technology
The employed roll squeezer version of cement industry is two cylindrical roll parallel arranged layouts at present, realize fragmentation to material by the pure thrust between two roll surfaces, two roll surfaces of its pairing work have identical roll surface speed, therefore do not have the role of tear to material, material behind attrition crushing very easily forms the material cake, need configuration beater material cake to break up, increased the energy consumption of material crushing system.
The utility model content
Weak point for existing roll squeezer above-mentioned, the purpose of this utility model provides a kind of novel roll squeezer, can increase the role of tear to material in the crushing material, is conducive to the fragmentation of material, can reduce again the formation of material cake, improve broken fineness.
In order to realize above purpose, the utility model by the following technical solutions: a kind of roller press, comprise the first pressure roller and second pressure roller of parallel placement, the first pressure roller of arbitrary cross-section is different with the roll surface diameter of the second pressure roller.
The roll surface of described the first pressure roller and the second pressure roller is shaped as single hop straight line, multistage straight line or cambered surface.
Roll squeezer equally adopts the parallel version of arranging of two roll shafts with existing roll squeezer, difference is that two roll surfaces of its pairing work have different roll surface diameters at arbitrary horizontal tangent plane place, when two rollers of roll squeezer during with identical angular speed revolution work, then has different linear velocities on two roll surfaces at place, same operating position, therefore it is in the role of tear that realizes having increased again when the conventional roll press is to material attrition crushing function to material, be more conducive to the fragmentation of material, reduced again the formation of material cake, improved broken fineness, can also remove the use of beater to reduce power consumption, simultaneously because the increase of contact-making surface, also improve accordingly the output of roll squeezer, improved the operating efficiency of roll squeezer.
Description of drawings
Fig. 1 is the structural representation of a kind of roller press of the utility model.
Fig. 2 is the linear velocity schematic diagram at two identical cooperation positions of pressure roller of the utility model place.
Reference numeral: 1-the first pressure roller; 2-the second pressure roller.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
A kind of roller press comprises the first pressure roller and second pressure roller of parallel placement, two parallel layouts of pressure roller, and the first pressure roller of arbitrary cross-section is different with the roll surface diameter of the second pressure roller.The first pressure roller of pairing work and the roll surface shape of the second pressure roller are determined as required, can satisfy arbitrarily for single hop straight line, multistage straight line or cambered surface etc. the roll surface form of the different condition of arbitrary cross-section roll surface diameter, the first pressure roller of pairing work and the roll surface diameter difference degree of the second pressure roller also can be determined according to the needs of the material of milling simultaneously, as long as satisfy instructions for use.
When the roll surface of the first pressure roller and the second pressure roller was shaped as shown in Figure 1 concavo-convex arc surface, under the effect of roll surface shape, this roll squeezer also had the effect of automatic aligning, can adapt to the situation of pan feeding wide fluctuations.
As shown in Figure 2, when two pressure rollers during with the revolution of identical angular velocity omega, because of the diameter R of the first pressure roller of its arbitrary cross-section
1Diameter R with the second pressure roller
2Difference has different linear velocity V on the linear velocity V=ω * R, the first pressure roller and the second roller surface
1, V
2Thereby being applied to has extruding and tears two kinds of power on the material, make the easier fragmentation of material, has avoided again the formation of material cake, has improved and has rolled fineness, has alleviated the live load of beater.Owing to the increase of contact-making surface, also improve accordingly the output of roll squeezer simultaneously, improved the operating efficiency of roll squeezer.
This roller press principle is simple, and handling ease both can be used for newly making roll squeezer, also can be used for the transformation of existing roll squeezer, and technical difficulty is little, is easy to promote.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can apparently expect some identical, replacement schemes, all should fall into the scope of the utility model protection.
