Description

Trolley support beam with dry ring cooler

This application claims priority to Chinese Patent Application No. 200910005655.7, entitled "A Supporting Beam for a Ring Cooling Trolley", filed on February 10, 2009, the entire contents of which are hereby incorporated by reference. Combined in this application.

Technical field

The invention relates to a ring cooler, in particular to a support beam for a ring cooler trolley.

Background technique

Referring to Figure 1, the structural diagram of the support beam of the existing ring cooler trolley. The ring cooler trolley support beam is used to support the trolley. The trolley support beam is arranged radially along the ring cooler, and its cross section (relative to the circumferential direction of the ring cooler) is triangular. The trolley support beams and rafts 103 are used to support the minerals cooled and transported by the trolley. In order to prevent the trolley from unloading after the trolley is unloaded, the mineral material is still accumulated on the upper part of the support beam of the ring cooler, and the support beam of the existing ring cooler trolley adopts a triangular beam structure.

The existing ring-cooling machine performs a circular motion of the hook speed. When passing through the loading area (including several trolley areas), the material is hooked on the trolley through the feed chute. The loaded trolley passes through the blast cooling zone, and the cold air is blown up from the lower bellows, passes through the raft 103, exchanges heat with the hot sinter mineral on the raft 103, and is discharged to the atmosphere through the chimney or directly. After about 1 hour, after the hot sinter is basically cooled, the trolley passes through the discharge area.

(including several trolley areas), the trolley wheel 104 moves along the unloading curved rail (not shown), so that the trolley body 105 is tilted around the ball hinge 106, and the seesaw 103 is tilted downward. The ore material on the seesaw 103 is discharged into a discharge chute (not shown). At the same time, due to the presence of the two side plates 102b of the triangular beam 102, the mineral material on the triangular beam 102 can slide down along the side plate 102b, so that the sinter material can be discharged into the discharge chute to complete the cooling process. Then, the trolley wheel 104 is along the reset track (not shown)

(The unloading track and the reset track form a continuous curved track) rise, and the body 105 is reset and then enters the loading area for loading, and the cycle begins again.

The triangular beam of the existing ring-cooling trolley support beam includes two side plates 102b and a bottom plate. In order to ensure a good supporting effect of the ring-cooling trolley support beam, the two side plates 102b and the bottom plate of the ring-cooling trolley support beam use blind plates.

When the ring cooler trolley is working, the slab ₁₀ 3 and the two side plates 102b of the support beam are filled with hot sinter minerals, and the cold air is forcibly blasted into the mineral layer from the slab 103 to be heated with the hot sinter Exchange, thus playing the role of cooling minerals. Because the wind will always pass along the least resistance, the shortest distance is passed. cold The wind is forced into the mineral layer from the raft 103, and most of the cold air passes from the A area above the raft 103 (see area A shown in Figure 1), after heat exchange with the mineral material, from the top of the mineral layer. Pass through the chimney or directly into the atmosphere. Since the three plates constituting the triangular beam are all blind plates, the upper B area of the bottom side of the triangular beam (see the B area shown in Fig. 1) has only a small amount or even no cold air entering, forming a cooling dead zone of the mineral material.

Therefore, how to provide a ring-cooling trolley support beam can solve the problem of poor cooling effect of the mineral material above the support beam of the ring-cooling machine trolley, which is a technical problem that a person skilled in the art needs to solve.

detailed description

The invention provides a support beam for a ring cooler trolley, which is used for improving the cooling effect of the mineral material above the support beam of the ring cooler trolley and effectively protecting the static sealing device of the trolley.

In order to more clearly illustrate the structure and working principle of the support beam of the ring cooler trolley of the present invention, the following detailed description will be made with reference to the accompanying drawings.

2 and FIG. 3, FIG. 2 is a structural view of a first embodiment of a support beam for a ring cooler of the present invention; FIG. 3 is an enlarged view of a portion I of FIG.

The support frame of the ring cooler trolley of the embodiment of the invention is used for supporting the ring cooler trolley. The ring cooler carriage support beam includes a rectangular beam 1 and a triangular beam 2 on the rectangular beam 1.

The upper wing of the rectangular beam 1 is extended to both sides to form the triangular beam bottom plate 21, and the widened portion of the upper wing of the rectangular beam 1 extending toward both sides is provided with a vent hole 21a. The sides of the triangular beam bottom plate 21 are adjacent to the raft plate 3. The seesaw 3 is used for ventilation. The seesaw 3 is an upper deck of the trolley.

A plurality of vent holes 21a may be provided in the widened portion extending on both sides of the upper wing of the rectangular beam, and the respective vent holes 21a may be independent or in communication with each other. Each of the vent holes 21a may have a circular cross section, or an elliptical shape, or a triangular shape, or a rectangular hole, or other polygonal shape.

On the two triangular beam side plates 22 adjacent to the triangular beam bottom plate 21, a plurality of dense small-section through holes 22a can be directly opened. The cross-sectional shape and area of the small-section through hole 22a are determined according to the size set by the upper deck of the ring cooler trolley. The size of the small-section through hole 22a is generally preset to be 8 to 12 mm.

The small section through hole 22a allows for ventilation.

The shape of the small-section through hole 22a may be a circle, an ellipse or a polygon. When the shape of the small-section through hole 22a is circular, the diameter is generally preset to be 8 to 12 mm.

When the ring cooler trolley is working, the slab 3 and the triangular beam side plate 22 are filled with the hot sinter mineral 4, and the cold air is forcibly blasted into the ore from the slab 3 and the small section through hole 22a on the triangular beam side plate 22. The layer 4 is heat-exchanged with the hot-sintered mineral material 4 to serve to cool the mineral material 4.

Since the small-section through hole 22a is provided on the triangular beam side plate 22, the ventilation area of the triangular beam side plate 22 is increased, and the cooling area of the entire ring cooler is expanded, so that the air volume per unit area of the ring cooler is reduced, and the average The wind speed has decreased. Since the resistance of the mineral material 4 decreases in proportion to the wind speed of 1.67, I.e., the case where P kv ^1. ^61), the ability to provide cooling air passage cold constant (i.e., the total pressure constant value), the ring cooler resistance is reduced, the amount of air supplied is increased for the fan. As the air volume increases, the mineral material 4 will get better cooling.

Since both the slab 3 and the triangular beam side plate 22 pass cold air, the wind speed inside the mineral layer and the surface of the mineral layer becomes more uniform, thus correspondingly reducing the occurrence of ash and improving the surrounding environment.

However, due to the presence of some of the bulk material and the powder in the mineral material, the bulk material and the powder material may fall into the interior of the triangular beam through the gusset gap or the crevice gap or the plate hole or the through hole. Part of the bulk material and powder entering the inside of the triangular beam is passed through the vent hole 21a of the triangular beam floor to the lower deck of the trolley, and a part of it is accumulated in the place where the triangular beam bottom plate is not open. In general, the bulk material and the powder accumulated on the bottom plate 21 of the triangular beam will not be scattered. Since the accumulated bulk material and the powder have a certain weight, the long-term operation with the ring cooler increases the load of the ring cooler operation. . The bulk material and the powder accumulated on the bottom plate 21 of the triangular beam may be thrown during the unloading and resetting process of the trolley. When the trolley is reset after unloading, the scattered mineral material is ventilated through the bottom plate of the triangular beam. The hole 21a falls onto the lower deck of the trolley, causing a jam between the static sealing device of the trolley and the sealing surface of the lower deck of the trolley, damaging the static sealing device and even damaging the trolley.

Therefore, the upper wing plate of the rectangular beam 1 may be provided with an inner triangular beam 5, and the inner triangular beam 5 includes two solid plates 51, 52 which are opposite to each other. The opposite sides of the two solid plates 51, 52 have a certain distance from the triangular beam bottom plate 21. In order to ensure that the trolley and the powder on the inner triangular beam 5 can smoothly slide down the inclined surface of the two solid plates 51, 52 of the inner triangular beam 5 to the lower plate of the trolley, the inner triangular beam 5 The angle between the two solid plates 51, 52 and the horizontal plane may be preset to be greater than or equal to the angle of repose of the mineral material cooled by the ring cooler trolley.

Thus, part of the bulk material and powder in the mineral material will fall directly along the two solid plates 51, 52 and pass through the triangular beam when they fall into the inner triangular beam 5 inside the triangular beam through the small-section through hole 22a. The vent hole 21a opened in the bottom plate 21 is dropped onto the lower plate of the trolley. At the same time, the trolley sill 3 also has a part of the material and the powder falling from the sill gap into the lower slab of the trolley. When the trolley is unloading, the lower deck of the trolley and the cooled ore on the trolley deck 3 and the triangular beam side panel 22 are discharged together into the discharge chute of the discharge zone (not shown). The inner triangular beam 5 can effectively prevent the accumulation of mineral material in the triangular beam 2. Bulk material and powder falling from the small-section through hole 22a of the triangular beam side plate 22 before the trolley is unloaded It has entered the lower deck of the trolley along the guide of the inner triangular beam 5, so during the reset of the trolley, there will be no accumulation of material falling onto the lower deck of the trolley, ensuring that the static seal of the trolley is reset in the trolley. During the process, no material is caught between the seal and the seal bracket and the sealing surface of the lower deck of the trolley, which effectively prevents the static seal of the trolley from being damaged due to the clamping, and prevents the trolley from being reset due to the clamping. It caused damage to the trolley and an accident.

In order to better prevent the accumulation of mineral material in the triangular beam 2, the inner triangular beam 5 and the triangular beam 2 may have the same length. The two solid plates of the inner triangular beam 5 are equal in length to the side plates of the triangular beam 2.

When the trolley is used for a long time, the impact of the mineral material during charging may cause the through hole on the triangular beam side plate 22 to become larger, and then the material having a larger granularity falls, due to the inner triangular beam 5 The angle between the two solid plates 51, 52 and the horizontal plane is greater than or equal to the angle of repose of the mineral material. Therefore, the larger-sized mineral material falling from the triangular beam 2 will also fall smoothly to the lower deck of the trolley, not in the trolley. Damage to the static seal or even damage to the trolley and accidents during resetting after unloading.

Of course, the angle between the two solid plates 51, 52 of the inner triangular beam 5 and the horizontal plane may be equal or unequal. As long as the angle between the two solid plates 51, 52 of the inner triangular beam 5 and the horizontal plane can satisfy the angle of repose of greater than or equal to the mineral material, it can be avoided that the accumulation material is scattered on the lower layer trolley when the trolley is reset after unloading. The sealing surface of the flat plate is sandwiched between the static sealing device of the trolley to prevent damage to the static sealing device.

The distance between the horizontal projection of the two solid plates 51, 52 of the inner triangular beam 5 and the vent hole 21a is preset to be zero to ensure that the ore material scattered from the triangular beam smoothly slides through the vent hole 21a to the trolley. Lower slab.

In order to more clearly explain the positional relationship between the support beam of the ring cooler and the entire ring cooler of the embodiment of the present invention, a detailed description will be given below with reference to Figs.

4 to FIG. 6, FIG. 4 is a plan view showing a second embodiment of the support beam of the ring cooler of the present invention; FIG. 5 is a cross-sectional view taken along line A-A of FIG. 4; and FIG. 6 is a cross-sectional view taken along line C-C of FIG.

The ring cooler includes a plurality of ring cooler trolleys 100, and the plurality of ring cooler trolleys 100 are arranged equidistantly and concentrically, and rotate together clockwise (clockwise in FIG. 4) or counterclockwise at the same speed. .

The process of unloading the trolley will be specifically described below with reference to FIG.

The wheel 100a of the trolley moves along a preset circular track (not shown). When a certain trolley moves to the discharge area, the wheel 100a of the trolley follows the unloading track (not shown) Moving downward, the trolley rotates along the rotating shaft 300 fixed on the supporting beam by the wheel 100a, and the rotating shaft 300 Specifically, it can be realized by a hinge, thereby driving the trolley sill 3 to be inclined downward to realize unloading. Since the portion of the support beam supporting the mineral material is the triangular beam 2, due to the presence of the two side plates 22 of the triangular beam, the mineral material on the side plate 22 on the left side of the front triangular beam (relative to the direction of motion of the trolley) can be along The trolley sill 3 that has been tilted downward is slid down, and the ore material on the side panel 22 on the right side of the rear triangular beam is simultaneously slid down along the aforementioned sloping trolley sill 3 to realize unloading. The above discharge process is repeated when the next adjacent trolley is moved to the discharge position.

The second embodiment of the ring cooler trolley support beam of the present invention differs from the first embodiment in that the through holes in the triangular beam side plates 22 are rectangular parallel to each other. Rectangular through-holes parallel to each other can be understood as three sets of through-hole groups directly formed on the triangular beam side plates 22 of the support beam (ie, the frame includes three sets of through-hole groups), and each set of through-hole groups is provided with a plurality of parallel or The approximately parallel elongated rectangular through holes 22b, and each of the elongated rectangular through holes 22b may have the same length dimension.

The rectangular long side of the rectangular through hole 22b may be parallel to the connection between the ring cooler trolley 100 where the support beam is located and the center of the ring cooler, or may have a certain angle with the connection.

In order to better ensure the cooling effect of the mineral material, the long side of each elongated rectangular through hole 22b may be much larger than the short side, and the length of the short side is equal to the size set by the seesaw 3.

The upper wing plate of the rectangular beam 1 of the ring-cooling trolley support beam according to the second embodiment of the present invention is extended to extend on both sides to form the triangular beam bottom plate 21, and the upper wing plate of the rectangular beam 1 extends to both sides to widen the portion A vent hole 21a is provided. A part of the cold air fed through the cold air passage (not shown) enters the mineral layer through the seesaw 3, and the other portion enters the inside of the triangular beam 2 through the vent hole 21a. Since the two triangular beam side plates 22 adjacent to the triangular beam bottom plate 21 are respectively provided with three sets of through hole groups, each through hole group further includes a plurality of elongated rectangular through holes 22b which are parallel to each other, and enters the triangular beam at this time. The cold air in 2 can enter the mineral layer above the support beam to cool the mineral material through the mutually parallel or nearly parallel elongated rectangular through holes 22b, thereby effectively increasing the air permeability area, thereby improving the mineral material above the support beam. Cooling effect.

After increasing the ventilation surface of the triangular beam side panel 22, the air volume per unit area is reduced, and the average wind speed is reduced, because the resistance of the mineral layer decreases proportionally to the wind speed of 1.67, ie (P = kv ^{1 6} , ) _o In the case where the cold air channel provides the same cold air capacity (ie, the total pressure value does not change), the ring cooler resistance decreases, and the air volume provided by the fan increases accordingly. As the air volume increases, the mineral material gets better cooling.

Since both the raft 3 and the triangular beam side panels 22 pass through the cold air, the wind speed inside the mineral layer and the surface of the mineral layer becomes more uniform, so the ash phenomenon is correspondingly reduced. Of course, the triangular beam side plate 22 of the embodiment of the present invention also includes two or more sets of through holes (ie, the frame of the triangular beam side plate 22 includes two or more sets of through holes), and each set of through holes The elongated rectangular through holes 22b may be included in an equidistant or non-equal distance distribution, and the size of each of the elongated rectangular through holes 22b may be the same or different.

In order to facilitate the processing of the triangular beam side plate 22, a plurality of sub-boards may be disposed on the frame of the triangular beam side plate 22, and the triangular beam side plates 22 having the gaps or through holes, that is, the triangular beam side plates 22, are sequentially assembled and assembled. A plurality of sub-boards are sequentially mounted on the frame to form a triangular beam side plate 22 having a gap or a through hole. The daughterboard may be a seesaw device, or a stringer device, or a plate hole device.

The seesaw of the seesaw device may be a strip-shaped steel plate parallel to the longitudinal direction of the trolley support beam to effectively support the larger particle size of the mineral material. The seesaw gap in the seesaw device can be used as a vent. The size of the jaw gap in the 板 plate device can be set according to the general setting of the upper raft plate 3 of the ring cooler trolley, generally preset to 8 ~ 12mm.

The rocker device may be sized to be aligned with the set of through holes (i.e., the frame) of the triangular beam side panel 22 for ease of disassembly, service, and installation.

The purlin of the purlin device can be specifically made of round steel, and the purlin can be placed horizontally in parallel with the longitudinal direction of the support beam of the trolley. The gap between the purlins of the purlin device can be used as a vent. The gap between the beams may be the same as the gap in the above-mentioned seesaw device, or may be slightly smaller than the gap in the seesaw device, and may be preset to be 8 to 12 mm.

The purlin device is sized to be aligned with the set of through holes (i.e., the frame) of the triangular beam side panel 22 for ease of disassembly, overhaul, and installation.

The plate hole device may be a steel plate having a plurality of dense small through holes, and the shape of the small through holes may be circular, elliptical, rectangular and other polygonal shapes. The small through hole of the plate hole device can be used as a vent hole.

The size of the plate hole device is arranged with the through hole group (i.e., the frame) of the triangular beam side plate 22 to facilitate disassembly, inspection, and installation.

Since the triangular beam side plate 22 has a ventilating raft or a purlin or a plate hole or a small cross-sectional rectangular through hole 22b, the cold wind entering the triangular beam can be smoothly entered into the mineral layer to cool the mineral material.

Also in order to ensure a good cooling effect, the cross-sectional area of each of the vent holes 21a needs to be greater than or equal to the cross-sectional area of each of the rectangular through holes 22b. And the total area of the cross section of the ventilation hole 21a is larger than the rectangular passage The total area of the cross-sectional area of the holes 22b.

The ring cooler trolley support beam of the present invention comprises a rectangular beam 1 and a triangular beam 2 on the rectangular beam 1. The upper wing plate of the rectangular beam 1 is extended to extend on both sides to form the triangular beam bottom plate 21, and the upper wing plate of the rectangular beam 1 is provided with a vent hole 21a extending toward the two sides, and the cold air enters through the raft plate 3 At the same time as the mineral layer, it is also possible to enter the inside of the triangular beam 2 through the vent hole 21a. Since the two triangular beam side plates 22 adjacent to the bottom plate of the triangular beam 2 are provided with a plurality of through holes 22a (first embodiment) or rectangular through holes 22b (second embodiment), entering the triangular beam 2 at this time The cold air can enter the B area as shown in FIG. 2 through the through holes 22a or the rectangular through holes 22b, and cool the mineral material in the B area, thereby improving the cooling effect of the mineral material above the support beam. The ring-cooling trolley support beam of the present invention can eliminate the cooling dead zone, that is, the B zone. Moreover, when the trolley is being charged and cooled, the bulk material and the powder scattered on the inner triangular beam 5 can smoothly slide down the inclined surface of the inner triangular beam 5 onto the lower deck of the trolley to prevent the upper wing of the rectangular beam 1. The accumulation of mineral materials on the board increases the operating load of the ring cooler; and it can avoid the damage of the static sealing device due to the accumulation of material when the trolley is reset after the discharge of the trolley, and even the phenomenon of damage to the trolley.

The above description is only a preferred embodiment of the present invention and does not constitute a limitation of the scope of the present invention. Any modifications, equivalents, and improvements made within the spirit and scope of the present invention are intended to be included within the scope of the appended claims.
