Abstract

The utility model discloses a flotation slime crusher. The flotation slime crusher adopts the structure that two rotating shafts are parallelly arranged in a slime feeding barrel body; bearing supports are arranged at the two ends of the rotating shafts; a plurality of cutters are uniformly distributed on the two rotating shafts, and are arranged in a mutually cross manner. After entering the crusher, materials to be crushed is crushed under the impact effect of the cutters with high rotating speed, the crushed materials obtain velocity energy from the cutters to move up reversely, the impact among materials is generated, the impact process is performed repeatedly until the materials are crushed to be in required grain size, and the crushed materials are discharged from the lower part of the crusher; fine particles and powdery materials subjected to repeatedly crushing fall into a discharge opening through fine gaps among crushing cutters and then are discharged outside the crusher.

Description

The coal slurry flotation disintegrating machine

Technical field

The utility model relates to disintegrating machine, relates in particular to coal slime breaker.

Background technology

At present, in the coal flotation, known machinery to the block coal slime of high-moisture, cleaned coal fragmentation has two kinds, wherein a kind of breaking capacity and strong adaptability to material, but complex structure, bulky, need in use to add dehydrating agent, very easily product is polluted, production and maintenance cost are higher.Another kind of simple in structure, consisted of by several groups of driving blades, do not need to add dehydrating agent, but to breaking capacity and the bad adaptability of material.

Summary of the invention

In order to overcome the deficiency of existing coal slime breaking device, the utility model provides a kind of novel coal slurry flotation disintegrating machine that utilizes the impact energy broken material.

The technical scheme that its technical problem that solves the utility model adopts is,

A kind of coal slurry flotation disintegrating machine, it comprises coal slime feed staving, it is characterized in that, parallel in the feed staving two rotating shafts are installed, the two ends of two rotating shafts are respectively equipped with bearing block, be evenly arranged on two rotating shafts and be fixed with some cutting knifes, the mutual arranged crosswise of cutting knife on two rotating shafts.

This coal slurry flotation disintegrating machine adopts two frequency converter motor-driven, and rotating speed is according to material and broken situation capable of regulating.

This coal slurry flotation disintegrating machine mainly is to come broken material by percussion, entered in the disintegrating machine by broken material, under the percussion of High Rotation Speed cutting knife and broken, broken material obtains kinetic energy from cutter, oppositely move up, mutually clash between material and the material, this process repeats, until material is crushed to desired particle size, till the discharge of machine bottom; Falling into discharging opening through the fine particle after the fragmentation repeatedly and granular material by the slight gap in the broken cutting knife like this is discharged from outside the machine.

Can reach the purpose that changes raw meal particle size and material shapes by changing the cutting knife size with the disintegrating machine rotating speed.

The beneficial effects of the utility model are:

1, this disintegrating machine is easy to install, and takes up room less, can directly carry out improvement and installation at equipment such as existing blanking groove, the grooves that connects material.

2, the ratio of reduction is large, discharging-material size is little, to breaking capacity and the strong adaptability of material, and does not need to add dehydrating agent.3, breaker is simple in structure, is easy to safeguard.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the top view of the utility model embodiment.

Fig. 2 is the cutter structure figure that is welded on the rotating shaft.

Fig. 3 is that the use securing member is fastened on the cutter structure figure on the rotating shaft.

Among the figure, 1-feed staving, 2-the first rotating shaft, 3-the second rotating shaft, 4-clutch shaft bearing seat, 5-the second bearing block, 6-the first cutting knife, 7-the second cutting knife, 8-circular hole.

The specific embodiment

A kind of novel coal slurry flotation disintegrating machine, it comprises coal slime feed staving 1, feed staving 1 interior parallel two rotating shafts that are equipped with, i.e. the first rotating shaft 2 and the second rotating shaft 3, the two ends that the two ends of the first rotating shaft 2 are respectively equipped with clutch shaft bearing seat 4, the second rotating shafts 3 are respectively equipped with the second bearing block 5; The first rotating shaft 2 has been evenly arranged some the first cutting knife 6, the second rotating shafts 3 and has been evenly arranged some the second cutting knifes 7; The first cutting knife 6 and the second cutting knife 7 fixed forms have two kinds, and the one, cutting knife as shown in Figure 2 will be welded on the rotating shaft; The 2nd, cutter structure form as described in Figure 3, the cutting knife afterbody is provided with circular hole 8, installs on the rotating shaft by circular hole, tightens up with securing member to get final product; The first cutting knife 6 and the second cutting knife 7 mutual arranged crosswise.

Claims

1. coal slurry flotation disintegrating machine, it comprises coal slime feed staving, it is characterized in that, parallel in the feed staving two rotating shafts are installed, the two ends of two rotating shafts are respectively equipped with bearing block, be evenly arranged on two rotating shafts and be fixed with some cutting knifes, the mutual arranged crosswise of cutting knife on two rotating shafts.
