The specific embodiment
The invention provides a kind of backbar of circular cooler trolley, be used to improve backbar top mineral aggregate cooling effect, and effectively protect the chassis static seal device.
Structure and operation principle in order to be illustrated more clearly in circular cooler trolley backbar of the present invention specify below in conjunction with accompanying drawing.
Referring to Fig. 2 and Fig. 3, Fig. 2 is the circular cooler trolley backbar first example structure figure of the present invention; Fig. 3 is an I part enlarged drawing shown in Figure 2.
The described circular cooler trolley backbar of the embodiment of the invention is used for the support ring cold machine trolley.Described circular cooler trolley backbar comprises rectangular beam 1 and three cantilevered corner beams 2 that are positioned on the described rectangular beam 1.
The upper flange of described rectangular beam 1 extends to both sides and widens the described three cantilevered corner beam base plates 21 of formation, and the upper flange of described rectangular beam 1 is provided with air vent 21a to both sides extension widened section.Three cantilevered corner beam base plates, 21 both sides and grate plate 3 are adjacent.Grate plate 3 is used for ventilating.Described grate plate 3 is a chassis upper strata grate plate.
Extend widened section in the upper flange both sides of rectangular beam a plurality of air vent 21a can be set, can be separate between each air vent 21a or be connected.The cross section of each described air vent 21a can be circle or ellipse or triangle or rectangular opening or other polygons.
Can directly offer a plurality of, intensive small bore through hole 22a on the adjacent two three cantilevered corner beam side plates 22 of described three cantilevered corner beam base plates 21.The size that the shape of cross section of small bore through hole 22a and area are set according to circular cooler trolley upper strata grate plate is determined.Generally be preset as 8～12mm.
Small bore through hole 22a can realize ventilation function.
The shape of small bore through hole 22a can be circle, ellipse or polygon.When small bore through hole 22a be shaped as circle the time, diameter generally is preset as 8～12mm.Because the through hole on the three cantilevered corner beam side plates 22 has increased the draught area of three cantilevered corner beam side plates 22, just expanded the film-cooled heat of whole central cooler, so the minimizing of unit are air quantity, mean wind speed decreases.The reduction that the resistance of mineral aggregate layer is directly proportional by 1.67 powers of wind speed, i.e. (P=kv
1.67).Provide (being that the total head value is constant) under the constant situation of cold wind ability at cold air duct, resistance reduces, and the air quantity that blower fan provides will correspondingly increase.Because the increase of air quantity, mineral aggregate will be cooled off better.
Because grate plate 3 and backbar all have cold wind to pass through, and make the wind speed of mineral aggregate layer inside and mineral aggregate laminar surface become more even, so the also correspondingly minimizing of dust phenomenon, surrounding enviroment improved.In order to be illustrated more clearly in the position relation of described circular cooler trolley backbar of the embodiment of the invention and whole circular cooler trolley, be specifically described below in conjunction with Fig. 4 to Fig. 6.
Referring to Fig. 4 to Fig. 6, Fig. 4 is the circular cooler trolley backbar second embodiment vertical view of the present invention; Fig. 5 is that A-A shown in Figure 4 is to cutaway view; Fig. 6 is that C-C shown in Figure 5 is to cutaway view.
Central cooler comprises a plurality of circular cooler trolleys 100, above-mentioned a plurality of circular cooler trolleys 100 successively, equidistantly and arranged concentric, together along (Figure 4 shows that clockwise direction rotates) clockwise or rotating with speed counterclockwise.
Specify the process of chassis discharging below in conjunction with Fig. 6.
The wheel 100a of chassis moves along default circular orbit (not shown), when certain trolley movement when needing the position of discharging, the wheel 100a of this chassis moves downward along track, chassis is under the drive of wheel 100a, along the rotating shaft 300 or the hinge through that are fixed on the backbar, move downward thereby drive this trolley grating plate 3, realize discharging.Because it is three cantilevered corner beams 2 that backbar supports the part of material, because the existence of two side plates 22 of three cantilevered corner beams, therefore, material on preposition three cantilevered corner beams (with respect to the trolley movement direction) can be along side plate 22 landings in preposition three cantilevered corner beams left side, material on rearmounted three cantilevered corner beams can be realized discharging along side plate 22 landings on rearmounted three cantilevered corner beam right sides.
When adjacent next chassis runs to discharge position, repeat above-mentioned discharge process.The difference of relative first embodiment of circular cooler trolley backbar second embodiment of the present invention is that the through hole on the described three cantilevered corner beam side plates 22 is the rectangle that is parallel to each other.
In order to guarantee that backbar top mineral aggregate has better cooling effect, directly offer three groups of sets of vias on the three cantilevered corner beam side plates 22 of the described circular cooler trolley backbar of second embodiment of the invention, every group of sets of vias comprises a plurality of being parallel to each other or approximately parallel rectangular through-hole 22b, and the length dimension of each rectangular through-hole 22b can be identical.
The long limit of the rectangle of rectangular through-hole 22b can be parallel to the line at backbar place circular cooler trolley 100 and described central cooler center, also can certain included angle be arranged with described line.
In order to guarantee the cooling effect of mineral aggregate better, the long limit of each rectangle can be much larger than minor face, and the length of minor face equals the size that grate plate 3 is set.
The upper flange of the rectangular beam 1 of the described circular cooler trolley backbar of second embodiment of the invention extends to both sides and widens the described three cantilevered corner beam base plates 21 of formation, and the upper flange of rectangular beam 1 is provided with air vent 21a to both sides extension widened section.The cold wind part that the cold air duct (not shown) is sent into enters mineral aggregate by grate plate 3, and another part enters into three cantilevered corner beams, 2 inside by air vent 21a.Because two the three cantilevered corner beam side plates 22 adjacent with three cantilevered corner beam base plates 21 are provided with three groups of sets of vias, each sets of vias comprises a plurality of rectangular through-hole 22b that are parallel to each other again, the cold wind that enters this moment in three cantilevered corner beams 2 just can cool off mineral aggregate by the mineral aggregate that these are parallel to each other or approximately parallel rectangular through-hole 22b enters into above the backbar, increase ventilative area effectively, thereby improved the cooling effect of backbar top mineral aggregate.
After increasing the ventilating surface of three cantilevered corner beam side plates 22, the unit are air quantity reduces, and mean wind speed decreases, because the reduction that the resistance of mineral aggregate layer is directly proportional by 1.67 powers of wind speed, i.e. (P=kv
1.67).Provide (being that the total head value is constant) under the constant situation of cold wind ability at cold air duct, resistance reduces, and the air quantity that blower fan provides will correspondingly increase.Because the increase of air quantity, mineral aggregate will better be cooled off.
Because grate plate 3 and backbar all have cold wind to pass through, and make the wind speed of mineral aggregate layer inside and mineral aggregate laminar surface become more even, so the dust phenomenon also correspondingly reduces.
Certainly, the described three cantilevered corner beam side plates 22 of the embodiment of the invention also comprise two groups or organize sets of vias more, the rectangular through-hole 22b that each sets of vias also can comprise equidistantly or not be equally spaced, and also the size of each through hole can be the same or different.
For the ease of the processing of three cantilevered corner beam side plates 22, a plurality of daughter boards can also be set on the through hole of three cantilevered corner beam side plates 22, install successively and constitute three cantilevered corner beam side plates 22 with gap or through hole.Described daughter board is grate plate device or grid section device or plate hole device.
Can offer several large-scale through holes on the described three cantilevered corner beam biside plates 22, then removable grate plate device, grid section device or plate hole device can be installed in each large-scale through hole.
The grate plate of described grate plate device can be bar steel plate, and with chassis backbar parallel longitudinal, thereby effective support is than the mineral aggregate of coarsegrain.Grate plate gap in the described grate plate device can be used as air vent and uses.Grate plate gap length in the grate plate device can be set by the routine of circular cooler trolley upper strata grate plate 3, generally is preset as 8～12mm.
The size of described grate plate device can with the large-scale through hole phase configuration of offering of described three cantilevered corner beam side plates 22, for convenience detach, maintenance and install.
The grid section of described grid section device specifically can adopt round steel, can be with the grid section horizontal positioned, with chassis backbar parallel longitudinal during installation.Gap between the grid section of grid section device can be used as air vent and uses.The big I in the gap between the grid section is identical with the gap in the above-mentioned grate plate device, also can be slightly less than the gap in the grate plate device, and general predeterminable is 8～12mm.
The large-scale through hole phase configuration that the size of described grid section device and described three cantilevered corner beam side plates 22 are offered, for convenience detach, maintenance and install.
Described plate hole device can be a steel plate of offering a plurality of intensive small through hole, and the shape of small through hole can be circular, oval, rectangle and other polygon.The small through hole of described plate hole device can be used as air vent and uses.
The large-scale through hole phase configuration of the size of described plate hole device and described three cantilevered corner beam side plates 22 can be dismantled, overhauls and be installed.
Because described three cantilevered corner beams have grate plate or grid section or the plate hole or the small bore through hole 22a that can ventilate, and can guarantee that the cold wind that enters three cantilevered corner beams enters the mineral aggregate layer smoothly, the cooling mineral aggregate.
But owing to exist part bulk cargo and powder in the mineral aggregate, these bulk cargos and powder just may drop into the inside of three cantilevered corner beams by described three cantilevered corner beam grate plate gaps or grid section gap or plate hole or through hole.Enter the bulk cargo of three cantilevered corner beam inside and a powder part and fall on the chassis lower floor flat board through the air vent 21a of three cantilevered corner beam base plates, some can accumulate down in the place that three cantilevered corner beam base plates are not held air vent.Generally speaking, these bulk cargo and powders that accumulate on the three cantilevered corner beam base plates 21 can not hang down, because the bulk cargo and the powder that accumulate have constant weight, for a long time with the central cooler running, have increased the burden of central cooler operation.These bulk cargo and powders that accumulate on the three cantilevered corner beam base plates 21 are understood the phenomenon that spreading takes place in chassis discharging and reseting procedure, when after the chassis discharging, resetting, the mineral aggregate that scatters is fallen on the chassis lower floor flat board through the air vent 21a of three cantilevered corner beam base plates, make material folding between the sealing surface of chassis static seal device and chassis lower floor flat board, damage static seal device even damage chassis.
Therefore, can be provided with interior three cantilevered corner beams 5 on the upper flange of described rectangular beam 1, described interior three cantilevered corner beams 5 comprise two solid slabs 51,52 that connect.The limit that described two solid slabs 51,52 connect and the upper flange of described rectangular beam 1 or and described three cantilevered corner beam base plates 21 between have certain distance.In order to guarantee that chassis is in the whole service process, in bulk cargo on three cantilevered corner beams 5 and powder can be slipped to chassis lower floor flat board smoothly along the inclined-plane of two solid slabs 51,52 of interior three cantilevered corner beams 5, two solid slabs 51,52 of interior three cantilevered corner beams 5 and the angle of horizontal plane can be preset as the angle of repose that is greater than or equal to the mineral aggregate that circular cooler trolley cools off.
Like this, part bulk cargo in the mineral aggregate and powder are on interior three cantilevered corner beams 5 that drop into three cantilevered corner beam inside by described three cantilevered corner beam grate plates or grid section or plate hole or small bore through hole 22a the time, will directly glide along two solid slabs 51,52, and drop to through the air vent 21a that offers on the three cantilevered corner beam base plates 21 on lower floor's flat board of chassis.Trolley grating plate 3 also has part spreading and powder to fall into lower floor's flat board of chassis from the grate plate slit simultaneously.When chassis carries out discharging, on chassis lower floor flat board and the trolley grating plate 3 and the cooling mineral aggregate on three cantilevered corner beams together be discharged to (not shown) in the chute of discharge zone.Interior three cantilevered corner beams 5 can effectively prevent to accumulate mineral aggregate in three cantilevered corner beams 2.Because the bulk cargo and the powder that fell from the grate plate of three cantilevered corner beam side plates 22 or grid section or plate hole or small bore through hole 22a before chassis carries out discharging just enter into chassis lower floor flat board along the guiding of interior three cantilevered corner beams 5, therefore at the reseting period of chassis, just not having buildup scatters chassis lower floor flat board, the static seal that has guaranteed chassis can material folding between the sealing surface of seal and seal holder and chassis lower floor flat board in the chassis reseting procedure, prevented that effectively the chassis static seal from being destroyed because of material folding, prevented that also chassis from damaging chassis and having an accident because of the material folding that resets causes.
In order to prevent to accumulate mineral aggregate in three cantilevered corner beams 2 better, interior three cantilevered corner beams 5 can have identical length with three cantilevered corner beams 2.Two solid slabs and described three cantilevered corner beams, 2 side plates of interior three cantilevered corner beams 5 are isometric.
When the long-term use of chassis, percussion because of the when filling with substance mineral aggregate, may cause the through hole on three cantilevered corner beams 2 to become big, fall with regard to the material that has than coarsegrain so, because two solid slabs 51,52 of interior three cantilevered corner beams 5 and the angle of horizontal plane are greater than or equal to the angle of repose of material, therefore, also can fall chassis lower floor flat board smoothly, damage static seal device even damage chassis in the time of can after the chassis discharging, not resetting and have an accident from the mineral aggregate that three cantilevered corner beams 2 fall than coarsegrain.
Certainly, two solid slabs 51,52 of interior three cantilevered corner beams 5 can equate with the angle of horizontal plane, also can be unequal.As long as two solid slabs 51,52 of interior three cantilevered corner beams 5 and the angle of horizontal plane can both satisfy the angle of repose that is greater than or equal to material, because of buildup scatters material folding between the sealing surface of lower floor's chassis flat board and chassis static seal device, prevent to damage static seal device in the time of just can avoiding after the chassis discharging, resetting.
The floor projection of two solid slabs 51,52 of interior three cantilevered corner beams 5 and the distance between the described air vent 21a need be preset as zero, to guarantee passing through air vent 21a landing smoothly to chassis lower floor flat board from the material that three cantilevered corner beams scatter.
In order to guarantee favorable cooling effect, the cross-sectional area of each air vent 21a is more than or equal to the cross-sectional area of each described through hole 22a equally.And the gross area of air vent 21a cross section is greater than the gross area of through hole 22a cross-sectional area.
In order to guarantee cooling effect, between lower floor's flat board of rectangular beam 1 and circular cooler trolley, can be provided with static seal device 6.
Static seal device 6 is specifically as follows the seal holder 62 that is fixedly mounted on rectangular beam 1 base plate, and with seal holder 62 hard-wired sealing strips 61.In order to guarantee sealing effectiveness, sealing strip 61 can run through whole rectangular beam 1, and sealing strip 61 length equal the length of rectangular beam 1 default seal section.
Circular cooler trolley backbar of the present invention comprises rectangular beam 1 and three cantilevered corner beams 2 that are positioned on the described rectangular beam 1.The upper flange of described rectangular beam 1 extends to both sides and widens the described three cantilevered corner beam base plates 21 of formation, and the upper flange of described rectangular beam 1 extends widened section to both sides and is provided with air vent 21a, when cold wind enters mineral aggregate by grate plate 3, also can enter into three cantilevered corner beams, 2 inside by air vent 21a.Because two the three cantilevered corner beam side plates 22 adjacent with described three cantilevered corner beams, 2 base plates are provided with some through hole 22a, enter the B district that three cantilevered corner beams, 2 interior cold wind just can enter into Fig. 2 by these through holes 22a this moment, cool off the mineral aggregate in B district, thereby improved the cooling effect of backbar top mineral aggregate.It is the B district that circular cooler trolley backbar of the present invention can be eliminated the cooling dead band.And when chassis charging, cooling operations, the bulk cargo and the powder that scatter on interior three cantilevered corner beams 5 can be slipped to chassis lower floor flat board smoothly along the inclined-plane of interior three cantilevered corner beams 5.
The above only is a preferred implementation of the present invention, does not constitute the qualification to protection domain of the present invention.Any any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
