The specific embodiment
The disintegrating machine relating to regard to an embodiment of the invention below with reference to Fig. 1 to Fig. 5 C describes.
Fig. 1 is the front view that represents disintegrating machine 10.Have again, figure 1 illustrates in the case of using with the axial vertical face of the rotor of disintegrating machine 10 and dissect the cross section disintegrating machine 10.Disintegrating machine 10 applies impact to the material in the broken space 14 of dropping into housing 18 inside in the input port 11 of housing 18 formation, thus by material fragmentation.Breaked material is discharged from outlet 12.
Disintegrating machine 10 possesses rotor 15 and is arranged on the multiple impact parts 16 on rotor 15 in the broken space 14 of housing 18 inside.Each impact part 16 is circumferentially arranged on rotor 15 at certain intervals along rotor 15.Use for example hammer as impact part 16.As shown in Figure 1, each impact part 16 also can be installed on rotor 15 via axle 16a, and impact part 16 is being hinged on this axle 16a around the mode of this axle 16a rotation.Therefore, each impact part 16 can swing centered by axle 16a.In addition,, although not shown, each impact part 16 also can be fixing not produce this swing with respect to rotor 15.
In addition, disintegrating machine 10 also possesses the impingement plate 20 of configuration around rotor 15 and the interior lining panel 30 arranging at the inner surface 21 of impingement plate 20.The inner surface 21 of impingement plate 20 is configured to has substantially circular-arc profile.Impingement plate 20 and interior lining panel 30 are made up of for example ferrous materials.In addition, also can have can be according to the requirement of the wear condition of interior lining panel 30 and/or product granularity adjustment and structure that gap between top ends rotary track and the interior lining panel 30 of impact parts 16 is suitably adjusted for impingement plate 20.
As shown in Figure 1, interior lining panel 30 also can be divided into multiple interior lining panel parts along the rotating rotary track of the top ends of impact part 16 (top ends rotary track).For example, interior lining panel 30 comprises the first interior lining panel parts 30A, the second interior lining panel parts 30B and the 3rd interior lining panel parts 30C that are arranged in order along top ends rotary track to outlet 12 from input port 11.By as described above interior lining panel 30 being divided into multiple interior lining panel parts, thereby can make the setting of disintegrating machine 10 and maintenance become easy.
In addition, at least two interior lining panel parts in multiple interior lining panel parts also can have same shape.For example, in the example shown in Fig. 1, the second interior lining panel parts 30B and the 3rd interior lining panel parts 30C have same shape., any of interior lining panel parts 30B, 30C all has same length and has along similarly bending shape of the top ends rotary track of impact part 16.Jointly change by a part that makes as described above multiple interior lining panel parts, thereby can improve the supply easness of parts and use easness.
In addition, as shown in Figure 1, near input port 11, the first interior lining panel parts 30A of configuration also can have the shape that linearity extends.Thus, have along compared with the situation of the shape of the rotary track bending of impact part 16 with the first interior lining panel parts 30A, can guarantee that the area of input port 11 is larger.Have, in the situation that the first interior lining panel parts 30A has rectilinear form, the first interior lining panel parts 30A also can have and other interior lining panel parts 30B, length that 30C is different again.
In addition, in disintegrating machine 10, be provided with the temperature guiding mechanism 40 that the temperature of the inner surface 31 to interior lining panel 30 is adjusted.Below, temperature guiding mechanism 40 is described.
First, the background of set temperature guiding mechanism 40 is described.As mentioned above, the moisture content in the low-order coal such as brown coal is very up to 50～60%.The in the situation that of in low order coal is dropped into disintegrating machine 10, low-order coal can be attached on the inner surface 31 of impact part 16 and/or interior lining panel 30 sometimes.In this situation, in the low-order coal that is attached to impact part 16, act on centrifugal force and/or the impulsive force with the material handling of new supply, therefore can expect that low-order coal can peel off from impact part 16.On the other hand, interior lining panel 30 is normally fixed.Therefore, the tendency that the washy low-order coal of adhering at the inner surface 31 of interior lining panel 30 is piled up is strong, substantially can not expect that it can peel off naturally.If it is not consider the situation that the low-order coal of adhering at the inner surface 31 of interior lining panel 30 increases cumulatively broken Efficiency Decreasing when low-order coal bumps against interior lining panel 30 and/or even broken space 14 sealed etc., therefore preferred.Therefore, expect the low-order coal of adhering on the inner surface at interior lining panel 30 31 to remove.
Can think that low-order coal is mainly to be caused by the contained a large amount of moisture of low-order coal with respect to the tack of the inner surface 31 of interior lining panel 30.Therefore, if reduce in the low-order coal of adhering at the inner surface 31 of interior lining panel 30, be at least the amount of moisture of the part that contacts with inner surface 31, can expect that low-order coal can reduce with respect to the tack of inner surface 31.Said temperature guiding mechanism 40 is to consider this point and the mechanism that arranges., temperature guiding mechanism 40 heats to reduce the amount of moisture of low-order coal, thereby easily low-order coal is peeled off from the inner surface 31 of interior lining panel 30 for the low-order coal that the inner surface at interior lining panel 30 31 is adhered to.
Below, describe with regard to the concrete formation of temperature guiding mechanism 40 referring to figs. 1 through Fig. 4 B.Fig. 2 is the front view of the interior lining panel of the disintegrating machine of Watch with magnifier diagram 1.Fig. 3 A represents to observe the side view in the situation of the first interior lining panel parts 30A of the interior lining panel 30 of Fig. 1 along the normal direction of the outer surface of the first interior lining panel parts 30A.Fig. 3 B is the cutaway view that represents to observe from IIIB-IIIB direction the situation of the first interior lining panel parts 30A of Fig. 3 A.In addition, Fig. 4 A represents to observe the side view in the second interior lining panel parts 30B of interior lining panel 30 or the situation of the 3rd interior lining panel parts 30C of Fig. 1 along the normal direction of the outer surface of interior lining panel parts 30B, 30C.Fig. 4 B is the cutaway view that represents to observe from IVB-IVB direction the second interior lining panel parts 30B of Fig. 4 A or the situation of the 3rd interior lining panel parts 30C.
As shown in Figures 1 and 2, temperature guiding mechanism 40 has: temperature from medium 42 to interior lining panel 30 supplying temperatures that adjust is adjusted medium supply unit 41; Feed to the temperature that interior lining panel 30 supplies with and adjust the supply pipe 43 that medium 42 passes through; Adjust with the temperature for discharging from interior lining panel 30 discharge pipe 44 that medium 42 passes through.Supply pipe 43 and discharge pipe 44 can be both metal tubes, and can be also flexible hose and rubber hose etc. has patience and flexible pipe arrangement for the replacing of interior lining panel 30 and the displacement of impingement plate 20 with impacting.To adjusting medium 42 at stream 33 supplying temperatures of locating in the inner part configuration than the inner surface of impingement plate 20 21.The temperature that the temperature of supplying with to stream 33 is adjusted medium 42 is higher than the temperature that is put to the low-order coal in disintegrating machine 10.For example, the temperature of the low-order coal of supplying with to disintegrating machine 10 is generally atmospheric temperature left and right, and with respect to this, the temperature that temperature is adjusted medium 42 is 100 ℃ of left and right.Have, if temperature is adjusted the excess Temperature of medium 42, interior lining panel 30 and low-order coal are by superheated again, and therefore low-order coal probably can be on fire.Therefore, make it can not become excessive high temperature to the temperature adjustment of temperature adjustment medium 42.Although this temperature is adjusted the kind of medium 42 and can at random be adopted,, can use the low pressure saturated vapor generating at such as steam boiler etc.
As shown in Fig. 2 to Fig. 4 B, stream 33 also can be formed on each interior lining panel parts 30A of interior lining panel 30, the inside of 30B, 30C.In Fig. 3 A and Fig. 4 A, dot respectively the stream 33 forming in the inside of each interior lining panel parts 30A, 30B, 30C.In Fig. 3 A and Fig. 4 A, Reference numeral 35a represents the inlet 35a for adjust medium 42 to stream 33 implantation temperatures, and Reference numeral 35b represents the outlet 35b for adjust medium 42 from stream 33 discharge temperatures.Have again, adjust medium 42 be saturated vapor in the situation that in temperature, during the stream 33 by interior lining panel 30 saturated vapor and interior lining panel 30 and low-order coal between carry out heat exchange, its result, saturated vapor condenses into water sometimes.Therefore, can think temperature adjust medium 42 discharge from outlet 35b with the state of liquid.Consider this point, outlet 35b also can be formed on the below of inlet 35a.In addition the shape of inlet and outlet and configuration and can adopt arbitrarily as design item with the connected mode of supply pipe 43 and discharge pipe 44.
Be not particularly limited the temperature of having passed through at supply pipe 43 being adjusted to the method that medium 42 supplies with to the stream 33 of interior lining panel 30.For example, supply pipe 43 and discharge pipe 44 also can link with inlet 35a and the outlet 35b of interior lining panel 30 respectively.In this situation, also can on impingement plate 20, form for the through hole by supply pipe 43, discharge pipe 44 and/or otch.Or as shown in Figure 2, supply pipe 43, discharge pipe 44 and inlet 35a, outlet 35b also can be connected through the stream 23 of the inside formation at impingement plate 20.
According to present embodiment, to adjusting medium 42 at stream 33 supplying temperatures of locating in the inner part configuration than the inner surface of impingement plate 20 21., the temperature of temperature guiding mechanism 40 is adjusted medium 42 and is directly contacted with interior lining panel 30 locating in the inner part than the inner surface of impingement plate 20.Therefore, can locate in the inner part the temperature of interior lining panel 30 to adjust than the inner surface of impingement plate 20.Therefore,, with clip as in the past the situation of the structure member for interior lining panel is installed between temperature adjustment medium and interior lining panel compared with, the heat that temperature can be adjusted to medium 42 is transmitted to interior lining panel 30 with low loss.Therefore, can efficiently the inner surface of interior lining panel 30 31 be heated.
Preferably, as shown in Fig. 3 B and Fig. 4 B, be formed between the stream 33 of interior lining panel 30 inside and the inner surface 21 of impingement plate 20, clipping the heat insulating member 36 that the heat for preventing temperature adjustment medium 42 is conducted to impingement plate 20 sides.Thus, the heat that temperature can be adjusted to medium 42 is transmitted to interior lining panel 30 with lower loss.As for example sticking adiabatic material on the back veneer 37 that stream 33 is sealed of heat insulating member 36.In this situation, use for example iron plate as back veneer 37.In addition the back veneer 37, stream 33 being sealed self also can be made up of the material with thermal insulation.Have again, in Fig. 1, although be only provided with temperature guiding mechanism 40 with respect to the interior lining panel 30 that is positioned at left side, also can be with respect to the similarly set temperature guiding mechanism 40 of interior lining panel 30 that is positioned at right side.
In addition, as in Fig. 3 A and Fig. 4 A by as shown in Reference numeral 34, on the outer surface 32 of interior lining panel parts 30A, 30B, 30C, also can be formed for fastener hole 34 fastening with respect to impingement plate 20 interior lining panel 30.
Then, with reference to Fig. 5 A to Fig. 5 C, the effect when using above-mentioned disintegrating machine 10 that the material such as brown coal is broken describes.
First, brown coal 13 materials such as grade are dropped into from input port 11.Input brown coal 13 collide with the impact part 16 of rotation, then knock the inner surface 31 of interior lining panel 30.The brown coal 13 that bump against inner surface 31 and be attached to the brown coal 13 on inner surface 31 and disperse to inner surface 13 have been shown in Fig. 5 A.
Because brown coal 13 continuously disperse to inner surface 31, so as shown in Figure 5 B, the brown coal 13 that are attached on inner surface 31 can increase.On the other hand, as mentioned above, in the stream 33 of inside that is formed at interior lining panel 30, stream has the temperature that temperature is higher than brown coal 13 to adjust medium 42.Therefore, adjusting medium 42 by temperature heats brown coal 13.This heating produces by the heat of conducting from temperature adjustment medium 42 through interior lining panel 30, and therefore the part contacting with inner surface 31 in brown coal 13 is preferentially heated.Therefore, the water content of the part contacting with inner surface 31 in brown coal 31 is because of lower than the water content of other parts of brown coal 13 owing to heating caused evaporation of water and/or movement.Its result, as shown in Figure 5 B, the part contacting with inner surface 13 in brown coal 13 becomes the drying nest 13a that water content has reduced.
As mentioned above, can think that low-order coal is mainly to be caused by the contained large quantity of moisture of low-order coal with respect to the tack of the inner surface 31 of interior lining panel 30.Here according to present embodiment, by making the part contacting with inner surface 31 in brown coal 13 dry, thereby can reduce the tack of brown coal 13 with respect to inner surface 31.In this situation, as shown in Figure 5 C, can expect, the suffered power of brown coal 13 of coming take the suffered power of the eddy current from producing because of the rotation of rotor 15 and impact part 16 and/or from dispersing to inner surface 31 etc., as opportunity, make the brown coal 13 that adhere at inner surface 31 peel off from inner surface 31.
As mentioned above, according to present embodiment, thereby by being heated, brown coal 13 can be peeled off from the inner surface 31 of interior lining panel 30 in brown coal 13.In addition,, according to present embodiment, in brown coal 13, be mainly that the part that contacts with inner surface 31 is dry by making, thereby brown coal 13 can be peeled off from inner surface 31.Therefore,, compared with for example whole broken space 14 being heated to the situation of the whole dry tack free that makes brown coal 13, can reduce for brown coal 13 are peeled off to required heat energy.In addition, can reduce brown coal 13 danger on fire.In addition,, according to present embodiment, temperature guiding mechanism 40 is configured to and contacts with interior lining panel 30 locating in the inner part than the inner surface of impingement plate 20 21.Therefore, can realize the heat conduction between interior lining panel 30 with low loss.Therefore, can efficiently the inner surface of interior lining panel 30 31 be heated.Like this, according to present embodiment, by the Overlay of these features, can remove efficiently the brown coal 13 that adhere at the inner surface 31 of interior lining panel 30 with heat energy still less.
Have again, can apply various changes to above-mentioned embodiment.One example of being just out of shape with reference to accompanying drawing below, describes.In the following description and in the accompanying drawing using in the following description, for the part that can form in the same manner with above-mentioned embodiment, use the Reference numeral identical with the Reference numeral that the corresponding part in above-mentioned embodiment is used, and the repetitive description thereof will be omitted.
In above-mentioned present embodiment, the temperature that shows temperature adjustment medium 42 is adjusted to the example of approximately 100 ℃.But the temperature that temperature is adjusted medium 42 needn't be adjusted into identical temperature without exception, also can change according to the position of interior lining panel 30 temperature of temperature adjustment medium 42.For example, in the situation that as described above interior lining panel being divided into multiple interior lining panel parts 30A, 30B, 30C, temperature guiding mechanism 40 also can be configured to the temperature of the inner surface 31 at least two interior lining panel parts in multiple interior lining panel parts 30A, 30B, 30C independently and adjust.Below the effect of this variation is described.
As the driving force that the brown coal that adhere on the inner surface at interior lining panel 30 31 13 are peeled off from inner surface 31, except the collision of the handled thing from being broken and/or from the suffered power of the eddy current that produces by the rotation of rotor 15 and impact part 16 etc., it is also conceivable that the gravity of effect on the brown coal 13 that are attached to inner surface 31.On the other hand, gravity depends on the direction of the inner surface 31 of interior lining panel 30 at the serviceability aspect brown coal 13 are peeled off from the inner surface 31 of interior lining panel 30.For example, in the disintegrating machine 10 shown in Fig. 1, can think that the brown coal 13 that adhere to are compared with the brown coal 13 that adhere on the first interior lining panel parts 30A on the second interior lining panel parts 30B and/or the 3rd interior lining panel parts 30C, more easily because the impact of gravity is peeled off.Like this, brown coal 13 peel off easness because of the position of the accompanying interior lining panel 30 of brown coal 13 different.Here,, according to this variation, temperature guiding mechanism 40 can be adjusted the temperature of each interior lining panel parts 30A, 30B, 30C independently.For example, can implement the first interior lining panel parts 30A supplying temperature not to be adjusted medium 42 and only the second interior lining panel parts 30B and the 3rd interior lining panel parts 30C supplying temperature adjusted to medium 42 these controls.Thus, the second interior lining panel parts 30B and the 3rd interior lining panel parts 30C that the brown coal 13 of can emphasis pair comparing with the first interior lining panel parts 30A are difficult to peel off heat.Thus, can when being peeled off this purpose by realization, the brown coal 13 that are attached to interior lining panel 30 reduce overall heat energy.
In addition, brown coal 13 with respect to the adhesion amount of interior lining panel 30 because of position different.In this situation, according to present embodiment, by independently the temperature of each interior lining panel parts 30A, 30B, 30C being adjusted, thereby the interior lining panel parts that can selectively brown coal 13 easily be adhered to heating can be peeled off brown coal 13 thus efficiently.In this situation, also can reduce overall heat energy by being attached in brown coal 13 on interior lining panel 30 are peeled off this purpose realizing.
Concrete formation for the temperature guiding mechanism 40 for independently the temperature of each interior lining panel parts 30A, 30B, 30C being adjusted is not particularly limited, and can adopt various formations.For example, as shown in Figure 1, also can on the supply pipe 43 for adjust medium 42 to each interior lining panel parts 30A, 30B, 30C supplying temperature each, be provided for temperature to adjust the adjustment valve 45 that the flow of medium 42 is adjusted.
