Description

A kind of pressure breaking machine of broken raw coal

Technical field

The utility model relates to a kind of crushers, particularly relate to a kind of pressure breaking machine to be crushed raw coal.

Background technique

Coal washing is an indispensable process of coal deep processing, and directly mined coal is original from mine Coal, raw coal has been mixed into many impurity in recovery process, and the quality of coal is also different, and fixed ash is small and fixed ash is big Coal it is mixed in together.Coal washing is exactly to reject the impurity in raw coal, or fat coal and low-grade coal are carried out disaggregatedly A kind of industrial technology.Generated product has been generally divided into spoil, middle coal, second class cleaned coal, first class cleaned coal after coal washing process, passes through Readymade coal after coal washing process is usually cleaned coal, by coal washing, can reduce Coal Transport cost, improve the utilization rate of coal, Cleaned coal is the energy that can generally do fuel, and the cleaned coal of bituminous coal is generally mainly used for coking, it wants desulfuration, the industry mistake such as decontamination Journey, to reach the standard of coking.To raw coal carry out it is broken be coal washing previous step, it is traditional that broken set is carried out to raw coal Standby is typically all to be carried out by the way of rolling, rolling, can be same to raw coal and stone class impurity during broken Shi Jinhang is broken, although broken movement can be completed, is detrimental to the screening to raw coal category, is unfavorable for subsequent sieve Work is selected, and this is the major defect for traditional technology.

Utility model content

The utility model provides a kind of pressure breaking machine of broken raw coal, can be carried out according to the size of raw coal block hardness Classifying crushing, thus facilitate the work of subsequent screening raw coal, and this is the main purpose for the utility model.

The technology employed by the present utility model is a kind of pressure breaking machine of broken raw coal comprising equal flitch, bullet Power plate and rolling wheel, the equal integral inclined setting of flitch, which, which has, one enters material path, if entering material path maincenter and being connected at this Dry thumb wheel, each thumb wheel are pivotally connected on which floor plate, the integral inclined setting of the elastic plate, which has one to roll Slot, the rolling groove enter material path with this and dock and be connected to, which is arranged right above the rolling groove, and in the outer of the rolling wheel Surface and this roll and form one between the top surface of bottom plate and roll gap, this, which is rolled, is provided with several springs on the bottom surface of bottom plate, if Doing the spring and being compressed makes this roll bottom plate sinking, so as to change the size for rolling gap.

The equal flitch includes bottom plate and two side plates, and two side plates are fixed at the bottom plate two sides, by the bottom Plate and two side plates enter material path around forming this.The elastic plate includes rolling bottom plate and two side baffles, two sides Baffle is fixedly connected on this and rolls bottom plate two sides, rolls bottom plate by this and two side baffles surround and form the rolling groove.

This rolls setting on the bottom surface of bottom plate, and, there are six the spring, three springs therein, which are triangularly arranged, to be arranged at this The side of bottom plate bottom surface is rolled, the other three spring, which is also triangularly arranged, is arranged in the other side for rolling bottom plate bottom surface.

The utility model has the following beneficial effects: raw coal initially enters when the pressure breaking machine work of the broken raw coal Enter in material path to this, then slided by the effect of gravity and uniformly enters in the rolling groove, this moment, rolling rotation It is dynamic, when raw coal, which passes sequentially through this, rolls gap, by the rolling wheel and this roll roll effect of the bottom plate to raw coal Power is crushed raw coal, and due to containing the bulks impurity such as stone, spoil in raw coal, and its density hardness is higher, when such miscellaneous When matter rolls gap by this, the impurity block of the big hardness of high density will not be grinded up, at this point, impurity block, which pushes this, rolls bottom Plate makes several spring contractions, and expands this and roll the size in gap, so that impurity block be enable to roll gap by this, is having When body is implemented, the size Control for rolling gap can be preset and pulverize the size of raw coal block, while can also be passed through The coefficient of elasticity for setting spring, controls the dynamics rolled.

Detailed description of the invention

Fig. 2 is the overlooking structure diagram of the utility model.

Fig. 3 is the position view that the utility model rolls several springs on bottom plate.

Specific embodiment

As shown in Figures 1 to 3, a kind of pressure breaking machine 20 of broken raw coal comprising equal flitch 40, elastic plate 50 and rolling Pinch roller 60.

The integral inclined setting of equal flitch 40, the equal flitch 40 include bottom plate 41 and two side plates 42, two side plates 42 are fixed at 41 two sides of bottom plate, enter material path 43 around forming one by the bottom plate 41 and two side plates 42.

Enter to be articulated with several thumb wheels 44 in material path 43 at this, each thumb wheel 44 is articulated on the bottom plate 41.

When raw coal enters material path 43 by this, raw coal can be made uniformly to pass through this by several thumb wheels 44 and enter material path 43。

The integral inclined setting of elastic plate 50, the elastic plate 50 include rolling bottom plate 51 and two side baffles 52, and two The side baffle 52 is fixedly connected on this and rolls 51 two sides of bottom plate, rolls bottom plate 51 and two side baffles 52 around shape by this At a rolling groove 53.

The rolling groove 53 enters the docking of material path 43 with this and is connected to.

The rolling wheel 60 setting rolls bottom plate 51 with this in the outer surface of the rolling wheel 60 right above the rolling groove 53 Top surface between formed and one roll gap 54.

When specific implementation, the shaft of the rolling wheel 60 can be driven to rotate by belt or gear, thus band Move the rolling wheel 60 rotation.

This rolls and is provided with several springs 55 on the bottom surface of bottom plate 51, and several springs 55 make this roll bottom plate 51 by compression Sink, so as to change the size for rolling gap 54.

As shown in figure 3, this, which is rolled, is arranged there are six the spring 55 on the bottom surface of bottom plate 51 when specific implementation, In three springs be triangularly arranged the side for rolling 51 bottom surface of bottom plate be set, the other three spring also row triangular in shape The other side for rolling 51 bottom surface of bottom plate is arranged in column, increases the whole pushing stability for rolling bottom plate 51 with this.

When the pressure breaking machine 20 of the broken raw coal works, raw coal is first into this and enters in material path 43, then borrows The effect of gravity is helped to slide and uniformly enter in the rolling groove 53, this moment, the rolling wheel 60 rotation, when raw coal passes sequentially through When this rolls gap 54, by the rolling wheel 60 and this roll bottom plate 51 to raw coal roll active force to raw coal carry out It is broken.

Due to containing the bulks impurity such as stone, spoil in raw coal, and its density hardness is higher, when such impurity passes through the stone roller When pressing gap 54, the impurity block of the big hardness of high density will not be grinded up, if at this point, impurity block pushes this rolls bottom plate 51 and make The spring 55 contraction is done, and expands this and rolls the size in gap 54, so that impurity block be enable to roll gap 54 by this.

When specific implementation, the size that the size Control for rolling gap 54 pulverizes raw coal block can be preset, The dynamics rolled can also be controlled by the coefficient of elasticity of setting spring 55 simultaneously.
