Description
Technical field
The utility model belongs to crushing mechanism technical field, is specifically related to a kind of four-roller crusher being added with baffle plate.
Background technology
Four-roller crusher is, by the extruding of upper and lower two groups of rollers, the material entering four-roller crusher is carried out fragmentation, makes the granularity requirements that the raw material of industry through fragmentation reaches suitable.In process of production, we find because the charging aperture of four-roller crusher is narrower, cause the material entering four rollers concentrate on roller epidermis face central shaft to position, cause four-roller crusher current fluctuation when fragmentation larger, four-roller crusher runs not steady, raw meal particle size after fragmentation is uneven, is difficult to meet the requirement of producing.The wearing and tearing of roller skin all concentrate on center, the roller epidermis face of longer distance in the axial direction there is no the phenomenon occurring wearing and tearing because essentially no material passes through, roller skin is caused to occur the middle phenomenon caved in because of wearing and tearing at short notice, for ensureing the crushing effect of four-roller crusher, we are forced to just carry out turning to the roller skin of four rollers at short notice, by the turning of unworn roller skin to the same flat with the roller skin of wearing and tearing, guarantee the smooth operating rate that just have impact on four-roller crusher like this in roller epidermis face, cause production declining, strengthen the amount of four roller Maintenance and Repair, increase maintenance cost, the life cycle of roller skin is caused to shorten, cost significantly rises.
In addition, in current four-roller crusher, four have very large gap between roller and apparatus casing, and broken grade height can cause material to leak down between gap, both wastes raw material, and affects fragmentation quality again.
Summary of the invention
The technical problems to be solved in the utility model is because the charging aperture of four-roller crusher is narrower, cause the material entering four rollers concentrate on roller epidermis face central shaft to position, cause four-roller crusher current fluctuation when fragmentation larger, four-roller crusher runs not steady, raw meal particle size after fragmentation is uneven, roller skin occurs caving in because of wearing and tearing in centre at short notice, and broken grade height can cause material to leak down between gap, for solving the problem, the utility model provides a kind of four-roller crusher being added with baffle plate.
The purpose of this utility model realizes in the following manner:
A kind of four-roller crusher being added with baffle plate, comprise support, upper part of the frame is provided with a pair top roll, bottom is provided with a pair lower roll, the top of described support is provided with a charging aperture, the length of charging aperture is slightly shorter than the axial length of top roll, and the width of charging aperture equals the diameter of a top roll, or is greater than the radius of a top roll but is less than the diameter of a top roll; Charging aperture is positioned at the center at support top; Baffle plate is fixed on the inwall at support top, is positioned at the top of the termination of top roll, the inner side of end edges.
The left and right sides of described top roll is respectively arranged with baffle plate.
Described baffle plate is arc-shaped baffle.
The roller epidermis surface build-up welding of described top roll and lower roll has wear-resisting alloy electrode.
Relative to prior art, charging aperture extends to suitable with the length of roller along the axial direction of roller by the utility model, the material making to enter four-roller crusher through charging aperture is uniformly distributed along the axial direction of four roller roller skins, four-roller crusher is operated steadily, and ensure that the wearing and tearing of roller skin are more even, thus solve that the fragmentation that four-roller crusher causes because charging is uneven is not good, disintegrating machine run unstable, fault is more, the breakage of roller skin is too fast, the problems such as maintenance cost rising.Add curved baffle in the both sides of roller, block material with baffle plate, avoid material from the slit source between four roller both sides, improve the broken grade of fuel, reducing the impact on producing, having saved raw material.In addition, the four-roller crusher that the utility model provides, the roller epidermis surface build-up welding of top roll and lower roll has wear-resisting alloy electrode, can extend the service life of roller.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
Wherein, 1 is support; 2 is top rolls; 3 is lower rolls; 4 is charging apertures; 5 is baffle plates.
Detailed description of the invention
As shown in accompanying drawing 1-2, a kind of four-roller crusher being added with baffle plate, comprise support 1, support 1 top is provided with a pair top roll 2, and bottom is provided with a pair lower roll 3, and the top of described support 1 is provided with a charging aperture 4, the length of charging aperture 4 is slightly shorter than the axial length of top roll 2, the width of charging aperture 4 equals the diameter of a top roll 2, or is greater than the radius of a top roll 2, is less than the diameter of a top roll 2; Charging aperture 4 is positioned at the center at support 1 top; Baffle plate 5 is fixed on the inwall at support 1 top, is positioned at the top of the termination of top roll 2, the inner side of end edges.The left and right sides of described top roll 2 is respectively arranged with baffle plate 5; Baffle plate 5 is arc-shaped baffle; Arc and two top rolls 2 of baffle plate 5 are tangent, but do not contact with two top rolls 2; The roller epidermis surface build-up welding of top roll 2 and lower roll 3 has wear-resisting alloy electrode.
The course of work of the present utility model is as follows: material to be comminuted enters in four roller pulverizers through charging aperture 4, material is comparatively evenly distributed on the axial direction of top roll 2, material is subject to the extruding force effect that two top rolls 2 rotate relatively, material is squeezed and nibbles mill, due to the barrier effect of baffle plate 5, coarsegrain material directly can not fall down from the two ends of top roll 2; And then enter between relative two lower rolls 3 rotated, utilize two lower rolls 3 to carry out squeezing, shearing and nibble mill, material is broken into the granularity of needs, and is exported by conveying equipment.
Charging aperture extends to suitable with the length of roller along the axial direction of roller by the utility model, the material making to enter four-roller crusher through charging aperture is uniformly distributed along the axial direction of four roller roller skins, four-roller crusher is operated steadily, and ensure that the wearing and tearing of roller skin are more even, thus solve that the fragmentation that four-roller crusher causes because charging is uneven is not good, disintegrating machine run unstable, fault is more, the breakage of roller skin is too fast, the problems such as maintenance cost rising.Add curved baffle in the both sides of roller, block material with baffle plate, avoid material from the slit source between four roller both sides, improve the broken grade of fuel, reducing the impact on producing, having saved raw material.In addition, the four-roller crusher that the utility model provides, the roller epidermis surface build-up welding of top roll and lower roll has wear-resisting alloy electrode, can extend the service life of roller.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for a person skilled in the art, do not departing under the utility model general idea prerequisite; can also make some changes and improvements, these also should be considered as protection domain of the present utility model.
